Description

Method and system for detecting splicing of material strips, checking material and managing remainder

Technical Field

The invention belongs to the technical field of material belt feeding, and particularly relates to a method and a system for material belt splicing detection, material checking and remainder management.

Background

Along with the development of industries such as electronics, 5G communication and the like, SMT chip mounters are also rapidly developed. In SMT component mounting production, in order to avoid using wrong materials, improve production stability, often need accurately detect the time point that component material area spliced to check the material after the concatenation, manage the material remainder simultaneously.

To achieve the above object, a photoelectric sensor is generally used to detect whether a splicing event of a material tape occurs by sensing light projection/shielding of the splicing tape. After the material belt splicing is detected, an operator is informed to carry out material check and material remainder management by manually scanning the information on the material tray. Due to the difference of colors, materials and the like of the splicing tapes or the difference of splicing methods, the sensing effect of the optical signals is different, so that the success rate of detecting the splicing event of the material tapes by the photoelectric sensor is too low or false detection occurs (the material tapes are not spliced actually, but the material tapes are spliced by false identification). Therefore, the splice of the discharging belt cannot be detected in time without checking the material, and thus, wrong components are attached. Unnecessary shutdown can occur during false detection, and production efficiency is affected. In addition, even if a material strip splicing event is correctly detected, the material needs to be manually scanned to perform checking and remainder management, so that the efficiency is low, and operation errors are easy to occur. The present invention has been made to solve the above-mentioned problems.

A bar code (not shown) is also provided on the tray of the splice tape 80 on each supply rack 52, with material information (including material name, type and quantity) recorded on the bar code.

It should be noted that, in the embodiment of the present invention, a communication connection such as a wireless signal connection (wifi wireless router 60) is provided between the product line management system 10 and the chip mounter 50 in the product line, an internal communication module is built in the chip mounter 50 (for convenience of description and distinction, the internal communication module in the chip mounter 50 is described as a second internal communication module 54), and the chip mounter 50 is in communication connection with the corresponding product line management system 10 through the second internal communication module 54.

More specifically, as shown in fig. 4, for any production line management system 10, the system includes five functional modules, i.e., a first internal communication module 11, an external communication module 12, a material strip 80 splicing management module 13, a material checking management module 14, and a remainder management module 15. The data communication between the external communication module 12, the material strip 80 splice management module 13, the material strip 80 splice management module 14 and the remainder management module 15 is implemented by the first internal communication module 11, and meanwhile, the data communication between the four modules and the chip mounter 50 in the production line is also implemented by the first internal communication module 11, that is, the first internal communication module 11 performs the data communication between the other functional modules (that is, the above-mentioned external communication module 12, the material strip 80 splice management module 13, the material strip check management module 14 and the remainder management module 15) and the chip mounter 50 in the production line. The external communication module 12 performs data communication with other functional modules (the first internal communication module 11, the tape 80 splice management module 13, the material collation management module 14, the remainder management module 15) and the manufacturing execution system 20 outside the production line. The specific structure and operation principle of the first internal communication module 11, the external communication module 12 and the second internal communication module 54 are all conventional wireless communication modules, and are not described and limited.

The tape 80 splice management module 13 may parse the information acquired from the first internal communication module 11 and manage the parsed tape splice event information (including, for example, the splice event occurrence time, the equipment pass number, the trolley 51 pass number, and the feeder station, that is, when, which chip mounter 50, which trolley 51, and which feeder, although the tape splice event information may alternatively include, for example, which mounting head, which table, the supply rack serial number, the splice material ID, the substrate ID, the material remainder, and the like). Meanwhile, the first internal communication module 11 notifies the material check management module 14, that is, issues a material check notification, when it is determined that the check material tape 80 has a splice event.

The material verification management module 14 obtains the material verification information (preferably, including the target device, that is, the mounter 50, the trolley 51, the feeder address, the material information before and after the splicing, that is, which device, which trolley 51, which feeder, and the material name and quantity information of the spliced material tape 80, of course, may also include, for example, a production lot ID, etc., a material ID, a remainder, a substitute, etc.), after receiving the event notification of the splicing of the detected material tape 80, and sends the information to the manufacturing execution system 20 through the external communication module 12 to perform the material verification, the manufacturing execution system 20 performs the material verification after receiving the material verification information, and feeds back the verification result to the product line management system 10, and the material verification management module 14 controls the next operation of the target device according to the fed-back material verification result. The material checking result has two cases, namely, the checking OK is successful, and the checking NG is unsuccessful, and the information is inconsistent, namely, the spliced material belt 80 is inconsistent with the components to be mounted. When the checkup is OK, the production proceeds, and the material checkup management module 14 sends a checkup success notification to the remainder management module 15 through the first internal communication module 11. And when NG is checked, the material checking management module 14 sends a notification to the corresponding chip mounter 50 through the first internal communication module 11, so that the chip mounter 50 stops production and alarms to display wrong or unsuccessful information, so that an operator can know the specific reason of stopping production.

The remainder management module 15 receives the verification success notification sent by the material verification management module 14 after the verification OK, acquires information for material remainder management (including the object device, the dolly 51, the feeder address, the name and number of the spliced materials, and may also include, for example, a work table, a production lot ID, a spliced material ID, and the like), and sends the information for material remainder management to the manufacturing execution system 20 through the external communication module 12 to notify the material remainder update management. That is, the remainder management module 15, after receiving the notification of successful material check, obtains the number of the die attach machine 50, the number of the die attach truck 51, the station of the feeder, and the name and number of the spliced material tape 80 corresponding to the splicing of the material tape 80, and then sends this information to the manufacturing execution system 20 to notify the management of material remainder update, that is, sends the notification of material remainder update to the manufacturing execution system 20.

As shown in fig. 4, the manufacturing execution system 20 includes two functional blocks, one is a material checking functional block 21 and one is a remainder management functional block 22.

The material checking function module 21 performs a check comparison between the received information and the material information of the object production program managed in the system after receiving the material checking notification sent by the production line management system 10, and feeds back the check result to the production line management system 10, and the material checking management module 14 of the production line management system 10 performs a next action of the object device, that is, continuous production or stop production, according to the feedback result.

After receiving the material remainder update notification sent by the material remainder management function module, the remainder management function module 22 queries the remainder information of the existing object material according to the key information (such as product batch, equipment number, trolley 51 number, station position of the feeding frame 52 and material name) capable of positioning the unique object in the received information, and adds the remainder information with the received quantity information of the spliced material to obtain material remainder information, and then updates the material remainder information of the object material managed in the system, so that an operator can timely supplement the material when the material remainder is close to zero even grasping the material remainder in production, thereby ensuring the continuity of production and reducing shutdown in production.

For the electronic tag 71 system 70, which includes the electronic tag 71 and the tag reader 72, the tag reader 72 may read information stored in the electronic tag 71 and transmit the read tag information to the product management system 10 through the second internal communication module 54 in the chip mounter 50, so that the material strip 80 splicing management module 13 of the product management system 10 analyzes the information to analyze and manage splicing event information of the material strip 80. In some preferred embodiments of the present invention, the electronic tag 71 is an NFC or RFID tag, and may store the specified information. Correspondingly, the tag reader 72 is an NFC or RFID reader. As shown in fig. 2, as a top view structure consciousness diagram of a chip mounter 50, a trolley 51 is respectively disposed at the upper and lower ends of the chip mounter 50, each trolley 51 corresponds to one or more feeders, eight feeding frames 52 are disposed on each feeder at intervals side by side along the left-right direction, a splicing material belt 80 is disposed on each feeding frame 52, a mounting head 53 is movably disposed on the chip mounter 50 along the XY axis direction and above the feeder, a tag reader 72 such as NFC or RFID tag reader 72 is disposed on the mounting head 53, that is, above the feeding frames 52, when the splicing material belt 80 on any feeding frame 52 gradually approaches the tag reader 72 along with feeding of the feeder, that is, the electronic tag 71 on the splicing material belt 80 enters into the readable distance of the tag reader 72, and the tag reader 72 automatically reads the tag information stored therein. As an alternative embodiment, the tag reader 72 may be disposed at other positions of the chip mounter 50, so long as it is capable of reading information of the electronic tag 71 on the splicing tape 80 in the feeding process at a suitable position, and the specific position is selected and designed according to actual requirements, for example, the housing of the chip mounter 50 above the feeding frame 52 facing the splicing tape 80 on the feeder as shown in fig. 3.

The label printing system includes a PDA 30 (Personal DIGITAL ASSISTANT) for the label information reading module 31 and the label information editing module 32, and a label printing apparatus 40. It should be noted that the embodiment of the present invention is directed to the manual splicing operation of the tape 80. When the splicing material strip 80 is automatically spliced by a robot such as an industrial manipulator, the functions corresponding to the PDA 30 may be integrated into the control system of the robot. More specifically, the operator uses the PDA 30 to scan the bar codes on the feeders and trays (each having a bar code specific to distinguish between them, such as which mounter 50 the feeder corresponds to, which trolley 51 and which station the feeder frame 52 is located in, in particular), and then the tag information reading module 31 can obtain the address information of the feeder to be spliced (i.e., the number of the die mounter 50, the number of the die carrier 51 and the station of the feeder) and the material information (the material name, the type and the number) in the tray to be spliced from the bar code information. The tag information editing module 32 is used for an operator to automatically edit the information acquired by the information reading module 31 according to rules defined by the own needs (the different users need not be consistent, so that detailed description is omitted here, and the method is exemplified, the sequence of each information item is set up, the identification information of the identification factory and the product is added), and the edited information is transmitted to the tag printing device 40 after the editing is completed.

The label printing apparatus 40 has an electronic label 71 printing module 41 (NFC/RFID label printing module 41) therein, and automatically prints out an electronic label 71 (NFC/RFID label) containing label information of a unique locatable object to be attached to the splicing tape 80 upon receiving the information transmitted from the PDA 30.

The method for splicing and detecting the material strip 80, checking the material and managing the remainder according to the embodiment of the invention, referring to fig. 5 and 6, comprises the following steps:

After the material strips 80 are spliced, an electronic tag 71 is stuck on the spliced material strips 80, and the electronic tag 71 comprises address information of a feeder corresponding to the spliced material strips 80, a station position of a feeding frame 52, material information and quantity information of the spliced material strips 80;

The information of the electronic tag 71 is read by the tag reader 72 during the feeding process of the feeder, and the read information (the information includes the tag information on the electronic tag 71 and also includes the reading time, and the reading time corresponds to the splicing occurrence time of the material strip 80) is sent to the line management system 10 of the corresponding line;

the line production management system 10 judges whether an event of splicing the raw material belt 80 occurs according to the received information, and if the event of splicing the raw material belt 80 occurs, the line production management system 10 sends the information to the manufacturing execution system 20 outside the line production to inform the material checking;

after receiving the material checking notification, the manufacturing execution system 20 performs checking comparison on the received information and the material information of the object production program, and feeds back the checking result to the corresponding production line management system 10;

the line management system 10 controls the operation of the target equipment according to the material checking result fed back by the manufacturing execution system 20, if the checking is OK, the production is continued, and meanwhile, related information is sent to the manufacturing execution system 20 to inform the updated material remainder;

upon receiving the material remainder update notification, the manufacturing execution system 20 updates the remaining amount information of the target material managed in the system.

More specifically, the operation flow of the material strip 80 splice detection and material check and remainder management system according to the embodiment of the present invention is as follows:

After the operator or robot splices the material tape 80, the electronic tag 71 capable of uniquely positioning the tag information of the object is printed after the bar code on the tray is spliced by the scanned object feeder and the material tape 80, and is attached to the spliced material tape 80, referring to fig. 5. It should be noted that, the scanning order does not affect the label information of the finally obtained electronic label 71 attached to the splicing tape 80, that is, the scanning order is irrelevant, whether the barcode on the feeder is scanned first or the barcode on the splicing tray of the tape 80 is scanned first, the label information of the finally obtained electronic label 71 attached to the splicing tape 80 is unchanged.

In the process of mounting components, the chip mounter 50 continuously feeds the feeder, the electronic tag 71 at the splicing position of the material belt 80 approaches and reaches within the readable distance of the tag reader 72, and the tag reader 72 automatically triggers the reading of the tag information on the electronic tag 71 and transmits the tag information to the corresponding product management system 10.

The material strip 80 splicing management module 13 of the product line management system 10 analyzes the received information and determines whether a material strip 80 splicing event occurs, and the tag reader 72 can determine that the material strip splicing occurs as long as the tag reader 72 reads the electronic tag 71 attached to the spliced material strip 80, because the electronic tag 71 is attached to the spliced material strip. When a splice event of the detected web 80 occurs, the relevant information is sent to the manufacturing execution system 20 to notify the material check. When the splice event of the undetected tape 80 occurs, as shown in fig. 6, the feeder feeds, and the mounting head 53 sucks the component mounting without performing the subsequent tape splice management, material collation, and remainder update management.

Upon receiving the material verification notification, the manufacturing execution system 20 performs a verification comparison between the received information and the material information of the object production process managed in the system, and feeds back a verification result (verification OK or verification NG) to the corresponding production line management system 10.

The production line management system 10 controls the operation of the target equipment based on the material verification result fed back from the manufacturing execution system 20. Specifically, when checking OK, the production is continued, and the remainder management module 15 sends related information to the manufacturing execution system 20 to notify the updated material remainder, and when checking NG, the chip mounter 50 in the corresponding production line is notified to stop production and alarm to display corresponding information, so that an operator or a robot can know the production problem in time and make countermeasures in time.

After receiving the material remainder update notification, the manufacturing execution system 20 queries the remainder information of the existing object material according to the key information (for example, product lot, equipment serial number, station of the feeding rack 52, material name) capable of locating the unique object in the received information, and adds the remainder information with the received quantity information of the spliced material to update the residual information of the object material managed in the system.

It should be noted that the material in the embodiment of the present invention refers to the elements in the tray for splicing the material tape 80.

By adopting the system and the method provided by the embodiment of the invention, the splicing event of the discharging belt can be accurately detected in the production process, and meanwhile, the automatic check of the material information and the automatic update management of the material remainder are realized. The problem of false detection caused by splicing and detecting the material strips by adopting the photoelectric sensor in the prior art is reduced, and the efficiency is greatly improved.
