Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present application, it should be noted that, unless explicitly stated and limited otherwise, the terms "connected," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected. The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art. In addition, when describing a pipeline, the terms "connected" and "connected" as used herein have the meaning of conducting. The specific meaning is to be understood in conjunction with the context.

In embodiments of the application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

Currently, in a manufacturing factory of a manufacturing enterprise, when the operation time of a certain operation station (a manual operation station or a process equipment operation station) in a part assembly system far exceeds the planning operation takt time of a production line, the operation station is a bottleneck station in the part assembly system. The reasons for this may be that the work content of the station is relatively large, special assembly processes/special assembly modes/special materials are required to be carried out at the station, etc., resulting in a relatively long working time of the station. Thereby affecting the overall operational tact of the component mounting system.

In solving such bottleneck station problems, the main methods of the related art include the following:

1. The task of the bottleneck station or process is transferred to other stations or processes in a cancelled or combined form. Because of a certain sequence of working contents of a plurality of stations in the assembly process of the parts, the workload of the bottleneck station can be transferred to the stations close to the bottleneck station. This approach may cause the stations to become new bottleneck stations, and therefore, in practical applications, it is often necessary to redistribute the working content of each station in the entire assembly system, which not only consumes more time, but also may not be balanced, and may generate new bottleneck stations.

2. The production line is mainly in the form of roller lines, plate chain lines, slide plate lines and the like, the bottleneck station operators or equipment are increased, the bottleneck station operators or equipment are required to readjust the production line, the required workload is large, the personnel or equipment are increased to require sufficient working space, and the sufficient working space may not exist in a factory.

3. The beat of the whole production line is reduced, and a production line is planned and arranged, so that the production beat of the whole factory is balanced. And more operators and equipment are needed to be newly added in planning and arranging a production line, the occupied working space is larger, and the working efficiency of each production line cannot be improved.

Based on the above, the embodiment of the application provides a component assembly method, which is applied to a component assembly system, wherein the component assembly system comprises a plurality of working stations and a plurality of conveying equipment, and the conveying equipment is used for conveying components to be assembled. That is, the method for assembling the parts provided by the embodiment of the application replaces the production line in the forms of roller lines, plate links, slide plate lines and the like by a plurality of conveying devices, the parts to be assembled are conveyed by adopting the conveying devices, and the running lines of the conveying devices can be flexibly configured and adjusted according to actual assembly requirements so as to meet the requirements of different production scenes, so that the assembly efficiency of the part assembly system can be improved.

The method for assembling the part comprises the steps of after identifying an initial bottleneck station in a plurality of operation stations, decomposing based on the operation content of the initial bottleneck station to generate a plurality of target stations, determining the operation station before the initial bottleneck station as a split operation station, determining the operation station after the initial bottleneck station as a converging operation station, planning a plurality of parallel operation sub-circuits between the split operation station and the converging operation station, and setting one or a plurality of target stations in each operation sub-circuit. In this way, when the target carrying equipment moves to the diversion operation station, the target operation sub-circuit corresponding to the target carrying equipment can be determined in the plurality of operation sub-circuits after the diversion operation station, and the target carrying equipment is controlled to move according to the target operation sub-circuit so as to enable the to-be-assembled part carried by the target carrying equipment to move to the target station in the target operation sub-circuit for assembly.

It can be seen that, in the component assembling method provided by the embodiment of the application, a plurality of carrying devices are adopted to replace a production line, so that after an initial bottleneck station is identified, a plurality of parallel operation sub-circuits can be directly planned between a diversion operation station and a confluence operation station, so that the plurality of carrying devices can move in the planned plurality of operation sub-circuits, a plurality of target stations in the plurality of operation sub-circuits can complete the work of the initial bottleneck station at the same time, and the working efficiency of the whole component assembling system is further improved. The method for assembling the parts, provided by the embodiment of the application, has the advantages that the plurality of target stations are determined based on the operation content of the initial bottleneck station, the excessive influence on the assembling rhythm of the operation content of one station is avoided, the assembling efficiency of the whole part assembling system can be further ensured, meanwhile, the parts are transported by adopting a plurality of transporting equipment, only the transportation line of the transporting equipment is planned again when the bottleneck station is adjusted, complicated equipment position adjustment or other large-scale changes are not needed, the labor and material cost can be obviously reduced, and the potential loss caused by production interruption during the rearrangement can be avoided.

For ease of description, embodiments of the present application will be described with reference to the accompanying drawings. Referring to fig. 1, a component mounting system according to an embodiment of the present application includes a plurality of work stations 101, a plurality of handling devices 102, and a component mounting device 103 (not shown in fig. 1).

The carrying device 102 is used for carrying a part to be assembled and is in wired or wireless communication connection with the part assembling device 103, so that the part assembling device can send a planned operation line to the carrying device 102, and control the carrying device 102 to sequentially move to the plurality of working stations 101 according to the planned operation line, so that a worker or process equipment located at each working station can assemble the part to be assembled.

In some embodiments, a robotic scheduling system is installed in the part assembly apparatus 103, by which the plurality of handling apparatuses 102 are controlled.

In some embodiments, a materials management system is also installed in the parts assembly apparatus 103 for managing the materials inventory in each of the work stations.

As a feasible implementation manner, the component assembling device 103 may determine the assembling condition of the component to be assembled according to the position of the handling device, further determine the material consumption information or the material inventory information in each working station, and update the material inventory condition in the material management system, so that after a certain condition is met, the material management system may automatically supplement the material in the working station to complete the material supplement.

As a feasible implementation manner, the part assembling device 103 moves the materials which are not needed to be used temporarily away from the operation station to the temporary storage area according to the queue condition of the parts to be assembled in the part assembling system, so as to reduce the occupation of the material area at the edge of the production line.

For example, the operation line shown in fig. 1 is an operation line of the handling device, and the handling device may be moved according to a planned operation line sequence to complete the assembly of the parts to be assembled.

It should be understood that the embodiment of the application does not limit the specific form of the to-be-assembled part, and in the practical application process, the to-be-assembled part can be set according to the assembly requirement of the part, and the working content of each working station can be set according to the specific form of the to-be-assembled part. As an example, as a viable implementation, the part to be assembled may be an automobile.

It should be understood that the handling device in the embodiments of the present application may be any type of automatic handling device such as an autonomous mobile robot (Automatic Mobile Robot, AMR), an automatic guided vehicle (Automated Guided Vehicle, AGV), an industrial robot, or an unmanned aerial vehicle, and the embodiments of the present application do not limit the specific form of the robot.

The component mounting apparatus 103 in the embodiment of the present application may be a terminal apparatus, for example, a personal computer (personal computer, PC), a notebook computer, a mobile apparatus, a tablet computer, a laptop computer, or the like, and the embodiment of the present application is not limited to the specific form of the electronic apparatus. Or the component assembling device 103 may be a single server or may be a server cluster formed by a plurality of servers, and in some implementations, the server cluster may be a distributed cluster server, which does not limit the specific form of the model training device in the embodiment of the present application.

It should be noted that fig. 1 is merely an exemplary structure of a component assembly system, and the component assembly system may include more or fewer devices, such as process devices capable of assembling a component to be assembled, etc., in a practical application, and the embodiment of the present application is not limited thereto.

The component assembly method provided by the embodiment of the application can be applied to the component assembly equipment 103 in a component assembly system. Referring to fig. 2, the method for assembling a part provided by the embodiment of the application includes the following steps:

S201, identifying an initial bottleneck station in the plurality of operation stations, and determining a plurality of target stations based on the operation content of the initial bottleneck station.

Bottleneck stations refer to a process in a production flow where the processing speed of the station is lower than that of other stations due to certain limitations (such as equipment capacity, manpower deficiency, process complexity, etc.), thereby limiting the throughput speed of the whole production line. Identifying and optimizing bottleneck stations is a key step in improving overall production efficiency.

When the initial bottleneck station is identified, the initial bottleneck station can be identified from two aspects of the assembly time and the assembly content of each operation station, if one operation station has longer assembly time for one part to be assembled, the reason may be that the assembly content of the operation station is more, or a special assembly process and a special assembly mode are needed for assembly, or some special materials for assembly exist, so that the processing speed of the operation station is lower than that of other stations.

It should be appreciated that as a feasible implementation, the job content of the initial bottleneck station may be decomposed, and all job steps of the bottleneck station may be recorded in detail first, including time consumption of each step, required resources, and the like. Further analysis of which steps are the longest in time consumption or the greatest in resource requirement, these steps are often the main contributors to the bottleneck. The job content of the initial bottleneck station is further divided into a plurality of simpler subtasks, one or more target stations are set for each subtask, and each target station is used for processing a part of the job content of the initial bottleneck station.

As another possible implementation manner, the assembly steps corresponding to each part to be assembled in the part assembly system are not identical, that is, the operation steps for each part to be assembled in the initial bottleneck station are different, so that the operation content of the special assembly process, the special assembly mode or the special material assembly can be determined in the operation content of the initial bottleneck station, and one operation station is correspondingly arranged for the operation content. That is, a target station is defined for handling the parts to be assembled having the specific operating steps.

S202, planning a plurality of parallel operation sub-circuits between the diversion operation station and the confluence operation station, and setting one or a plurality of target stations in each operation sub-circuit.

The splitting operation stations are operation stations positioned before the initial bottleneck station in the plurality of operation stations, and the converging operation stations are operation stations positioned after the initial bottleneck station in the plurality of operation stations.

Because the part assembly system has the part circulation sequence, the operation station before the initial bottleneck station is used as a diversion operation station and the operation station after the initial bottleneck station is used as a confluence operation station according to the part circulation sequence. And a plurality of parallel operation sub-circuits are planned between the diversion operation station and the confluence operation station.

It should be understood that the multiple operation sub-circuits described in the embodiments of the present application are located between the splitting operation station and the converging operation station, and only indicate the operation timing sequence of the handling device when the cargo assembly is performed, and the operation timing sequence reaches the splitting operation station first and then reaches the converging operation station through any operation sub-circuit. In practical applications, the specific merging position and splitting position of the multiple operation sub-circuits may be determined according to the layout in the working space or according to the actual requirements, which is not limited in the embodiments of the present application.

It should be noted that, the embodiment of the present application does not limit the specific forms of the parallel multiple operation sub-circuits, and the parallel multiple operation sub-circuits may be configured in multiple layout manners. For example, referring to fig. 3 and 4, fig. 3 and 4 schematically illustrate two parallel layouts of multiple operation sub-circuits, in which the arrow indicates the advancing direction of the handling device, and in practical application, specific adjustments may be made according to the layout situation in the factory.

After planning a plurality of parallel operation sub-circuits, one or more target stations can be arranged in each operation sub-circuit, so that when the carrying equipment operates through any operation sub-circuit, the parts to be assembled carried by the carrying equipment can be assembled in the target stations in the operation sub-circuit.

S203, determining a target operation sub-line corresponding to the target carrying equipment from a plurality of operation sub-lines after the diversion operation station when the target carrying equipment moves to the diversion operation station.

Wherein the target handling device is any one of a plurality of handling devices.

In the case where the target handling apparatus moves to the branching operation station, it is necessary to determine a target operation sub-line among a plurality of operation sub-lines after the branching operation station, so as to perform the assembly through a target station among the target operation sub-lines.

It will be appreciated that in order to avoid that the workload of a certain target station is much greater than that of other stations, i.e. to avoid that a certain target station becomes a new bottleneck station, a plurality of handling devices may be equally distributed into a plurality of operational sub-lines.

Thus, as a feasible implementation, among the plurality of operation sub-lines, the operation sub-line having the smallest number of handling devices may be determined as the target operation sub-line.

It will be appreciated that a minimum number of handling devices indicates a smaller number of parts to be assembled in the run sub-line, and thus may be determined as a target run sub-line to ensure that the assembly times of the individual run sub-lines are substantially consistent.

As a feasibility implementation manner, an operation sub-line different from an operation sub-line of a preceding handling apparatus of the target handling apparatus may be selected as the target operation sub-line from among the plurality of operation sub-lines.

As a feasible implementation manner, among a plurality of operation sub-circuits, an operation sub-circuit corresponding to an assembly order of a part to be assembled, which is carried by a target carrying device, in a cargo assembly system may be used as the target operation sub-circuit.

That is, the correspondence between the assembly order and the operation sub-line may be preset in the component loading system, and may be distributed evenly according to the operation sub-line, or may be distributed evenly according to the number of the target stations in the operation sub-line, for example, the operation sub-line a may correspond to the assembly order 1, 3,5, 7, etc., and the operation sub-line B corresponds to the assembly order 2, 4, 6, 8, etc., which is not limited in the embodiment of the present application.

As a feasibility implementation manner, an operation sub-line where a target station matched with a part to be assembled carried by a target carrying device is located may be selected from a plurality of operation sub-lines as a target operation sub-line.

It will be appreciated that there are some parts to be assembled which differ from other parts, such as precision machinery, optical instruments, etc., and which require very high precision in assembly. These parts require special assembly processes such as fine tuning, precise positioning, error compensation, etc. Or there may be some special assembly materials, etc., that may not be available at every target assembly station. Therefore, for such components to be assembled, it is necessary to select, from a plurality of operation sub-circuits, an operation sub-circuit in which a target station matching with the components to be assembled carried by the target carrying apparatus is located as a target operation sub-circuit.

As a feasible implementation, the target operational sub-line may be determined according to the material preparation of each operational sub-line of the plurality of operational sub-lines.

For example, the component assembling device may record material information in each operation sub-line, and if the material in one operation sub-line is less than the material required to be assembled by the component to be assembled, the operation sub-line may be removed, and the target operation sub-line may be selected from other operation sub-lines.

S204, controlling the target carrying equipment to move according to the target operation sub-line so that the to-be-assembled parts carried by the target carrying equipment can move to a target station in the target operation sub-line for assembly.

After the assembly of the target carrying equipment in the split assembly station is completed, the target carrying equipment can be controlled to move according to the target operation sub-circuit, so that the to-be-assembled part carried by the target carrying equipment moves to the target station in the target operation sub-circuit for assembly.

It can be seen that, in the component assembling method provided by the embodiment of the application, a plurality of carrying devices are adopted to replace a production line, so that after an initial bottleneck station is identified, a plurality of parallel operation sub-circuits can be directly planned between a diversion operation station and a confluence operation station, so that the plurality of carrying devices can move in the planned plurality of operation sub-circuits, a plurality of target stations in the plurality of operation sub-circuits can complete the work of the initial bottleneck station at the same time, and the working efficiency of the whole component assembling system is further improved. The method for assembling the parts, provided by the embodiment of the application, has the advantages that the operation content of the initial bottleneck station is decomposed into a plurality of target stations, the excessive influence on the assembling rhythm of the operation content of one station is avoided, so that the assembling efficiency of the whole part assembling system is ensured, meanwhile, a plurality of conveying equipment is adopted for carrying the parts, only the conveying line of the conveying equipment is planned again when the bottleneck station is adjusted, complicated equipment position adjustment or other large-scale changes are not needed, the labor and material cost can be obviously reduced, and the potential loss caused by production interruption during the rearrangement can be avoided.

In some embodiments, the materials and processes required to assemble the plurality of parts to be assembled may not be the same, the assembly steps of each work station in assembling the plurality of parts to be assembled may not be the same, and the material supplies in each assembly station are supplied in the assembly order. Therefore, a certain moving sequence is required to be ensured when a plurality of parts to be assembled in the part assembly system move, so that an operator or process equipment at each working station can determine assembly steps or assembly instructions of the parts to be assembled according to the moving sequence, and assembly is performed based on materials fed according to the assembly sequence, so that assembly is accurately completed.

Based on this, as a feasible implementation, please refer to fig. 5, s204 may be specifically implemented as:

S501, acquiring an assembly sequence of the parts to be assembled, which are carried by the target carrying equipment.

In a part assembly system, a plurality of parts to be assembled typically enter the system in a certain order, and the system also determines the order in which each work station assembles the parts according to the order in which the parts enter.

Since the plurality of handling apparatuses have only one operation line before the branching operation station, the situation that the sequence is changed does not occur, and after any handling apparatus enters the operation sub-line, the moving speed of the handling apparatus in each operation sub-line and the assembling speed of the target station are not necessarily the same, so that the situation that the assembling sequence is disordered may occur.

Based on this, the solution provided in this embodiment needs to determine the assembly order of each of the handling apparatuses according to the order of the handling apparatuses in the component assembly system, that is, the assembly order of the components to be assembled that are handled by the target handling apparatus.

S502, controlling the moving speed of the target carrying equipment in the target operation sub-line based on the assembly sequence, so that the sequence of the target carrying equipment reaching the confluence working stations is the same as the assembly sequence.

In order to ensure that the subsequent assembly is performed in the initial assembly order after the confluence work stations, the operation of the target handling equipment can be controlled based on the assembly order, so that the plurality of target handling equipment arrive at the confluence work stations in the order of the target handling equipment, that is, the order in which the target handling equipment arrives at the confluence work stations is the same as the assembly order.

In order to ensure that the parts can arrive at the confluence work station in the order of assembly, the system may dynamically adjust the speed of movement of the handling apparatus. If a part is expected to arrive at the confluence station in advance, the system may reduce the speed of its handling equipment, and conversely, if it is expected to arrive later, the speed may be increased, which is not limited by the embodiments of the present application.

Illustratively, "001", "002", "003", "004" in fig. 6 are the assembly order of the parts to be assembled, as shown in fig. 6. The assembly sequence of the parts to be assembled can be obtained before the split assembly station, and then the moving speed of the plurality of conveying equipment is controlled, so that the sequence of the parts to be assembled after the split assembly station is the same as the sequence before the split assembly station.

It can be seen that, according to the scheme provided by the embodiment, through obtaining the assembly order of the to-be-assembled parts carried by the target carrying equipment, and then controlling the moving speed of the target carrying equipment in the target operation sub-circuit based on the assembly order, so that the order of the target carrying equipment reaching the converging operation stations is the same as the assembly order, the order of the to-be-assembled parts in the whole part assembly system can be ensured to be unchanged, and then a plurality of operation stations can directly assemble a plurality of to-be-assembled parts based on the predetermined order, each procedure can be performed more smoothly, and waiting time, adjusting time and reworking time caused by disordered part order are reduced.

In some embodiments, when assembling the parts to be assembled, an abnormal situation such as an assembly error or an assembly failure may inevitably occur, and at this time, subsequent assembly work may not be continued, and subsequent assembly work needs to be performed after the abnormal situation is handled.

As a feasible implementation manner, referring to fig. 7, the method for assembling a part provided by the embodiment of the application further includes the following steps:

s701, identifying abnormal parts in the part assembly system, and determining the assembly sequence of the abnormal parts.

As a feasible implementation manner, when an operator and process equipment in the operation station determine that a part to be assembled is abnormal in assembly, the part to be assembled can be marked as an abnormal assembly, and then the part assembly equipment can identify the abnormal assembly for subsequent processing.

The assembly sequence of the abnormal assembly can be determined according to the assembly sequence of all the parts to be assembled in the part assembly system, and the embodiments of the present application are not described herein.

S702, controlling an abnormal conveying device for conveying the abnormal assembly products to move to an abnormal processing position so as to process the abnormal assembly products.

It should be understood that the exception handling bit may be a preset job station for handling exception conditions, or may be a specific location in a factory, which is not limited in this embodiment of the present application.

S703, after the abnormal part assembly processing is completed, controlling the abnormal conveying equipment to be inserted into other conveying equipment according to the assembly sequence of the abnormal part assembly.

It should be noted that, when the abnormal assembly is inserted into other handling devices, the assembly process before the insertion point is determined is completed, so as to avoid the situation of assembly omission.

For example, as shown in fig. 8, the "003" in fig. 8 indicates the assembly order of the abnormal assembly, and when the abnormal assembly is identified, the abnormal assembly can be moved to the abnormal processing position for processing, and then the abnormal assembly is inserted into other handling equipment (indicated by the white arrow in fig. 8) according to the assembly order of the abnormal assembly, so that the assembly order of the plurality of parts to be assembled is kept unchanged.

It should be appreciated that the exception handling bit may be one of a plurality of target stations, or may be a job station disposed outside of the run sub-line, which is not a limitation of embodiments of the present application.

It can be seen that, according to the component assembling method provided by the embodiment, the abnormal component is processed by setting the abnormal processing position in the component sorting system, so that the problem that the subsequent component to be assembled cannot be timely installed due to long processing time of the abnormal component is avoided, and the assembling efficiency of the component assembling system is further ensured.

Based on the above, the method for assembling the parts provided by the embodiment of the application further comprises the steps of determining the temporarily unnecessary materials in the operation station according to the cargo assembling sequence in the part assembling system, wherein the temporarily unnecessary materials possibly are the materials which are not required to be assembled in the subsequent parts to be assembled in the operation station, and moving the temporarily unnecessary materials away from the operation station so as to avoid occupying the operation space in the operation station.

It should be understood that the parameter information may include information about the size of the part to be assembled, the material to be assembled, the assembly step, etc., which the present application is not limited to.

It can be understood that the shunting display screen is arranged at the shunting operation station to display shunting information, so that a worker can know the running direction of a part to be assembled conveniently, and can make a decision rapidly, and invalid waiting or resource idling is avoided. By means of real-time data analysis, manpower, material resources and time resources can be allocated more accurately, smooth operation of each diversion link is ensured, and therefore overall operation efficiency is improved.
