Description

Method and device for correcting automatic insertion path

Technical field

The invention relates to an automatic insertion machine for the automatic insertion of electronic components into a printed circuit board (PCB). In particular, the invention relates to a method for the automatic insertion-to-path correction necessary for the insertion of electronic components into a PCB, and to a device for performing the method.

Background technique

In an automatic insertion machine for automatically inserting electronic components into a PCB, it is necessary to generate work preparation hours and instruction sheets in order to increase the efficiency of the automatic insertion machine. In order to effectively utilize the automatic insertion machine, the staff generates an automatic insertion path in advance, so that the automatic insertion machine can insert electronic components into the corresponding position of the PCB along the automatic insertion path. However, since the model for automatic insertion of the PCB is variable, the worker must create a new automatic insertion path whenever the PCB model is changed.

When resistive elements are automatically inserted into PCBs, various devices are required according to various electronic components. Also, the automatic insertion path and sequence are adjusted to the characteristics of the automatic insertion device and the inserted elements. In order to use the automatic insertion machine, the staff in this area determine the automatic insertion path in advance, and they compile the NC program and work instruction table. The above operation requires a skilled person with more experience and knowledge of the equipment. It takes a lot of time even for staff who have been working at this for a long time and find it exhausting to do everything by hand. Furthermore, because the paths and work instruction tables determined in this way do not improve the machine operation ratio, and the development of software for generating rational operating scenarios by means of the required computers.

However, the auto-inserted paths generated as described above are not as efficient as those generated directly by workers. Therefore, the worker partially modifies and stores the route, compares the stored route with the previously automatically generated route, and decides the most efficient route based on the comparison result. At this time, work instruction sheets and NC programs should be generated for the determined paths. However, when the automatic insertion route generated as described above is not the route required by the worker, the automatic insertion route should be corrected to the route required by the worker.

Hereinafter, operations of the apparatus and method for correcting an automatic insertion path according to the present invention will be described with reference to FIG. 10 . Fig. 10 shows a method for correcting an automatic insertion path according to an embodiment of the present invention.

In step S101, the control section 106 controls the automatic insertion path generation section 102 to generate a file about the initial automatic insertion path of the electronic components A, B, C, D, E, and F to be inserted into the printed circuit board 201a, as shown in FIG. 4 shown.

In step S102, the control section 106 controls the memory 108 to store therein the initial automatic insertion route generated by the automatic insertion route generation section 102.

In step S103 , the control section 106 reads out the initial automatic insertion path file stored in the memory 108 .

In step S104, the control section 106 constructs a connection state matrix about the initial automatic insertion route of the electronic component according to the automatic insertion route file read from the memory 108 (as shown in FIG. 4 ).

In step S105, the control section 106 controls the monitor 106 to display the initial automatic insertion path 201, the pattern 202, and the menu 203, as shown in FIG.

In step S106, the user controls the mouse 104a to correct the initial automatic insertion path, so as to obtain the corrected path.

The operation of correcting the initial automatic insertion path to the correction path is as follows. After the user controls the mouse 104a to place on the first path between the first element A and the second element B for deletion, when the user clicks the mouse 108a, the first path P1 is deleted from FIG. 4 . In the same way, the third and fourth paths P3 and P4 are also deleted. As shown in Figure 6, the first, third and fourth intermediate states have been deleted.

Thereafter, the user controls the mouse 104a, moves the cursor displayed on the monitor 110 to the first element A, and clicks the mouse 104a. After the user moves the cursor to the fourth element D through the operation of the mouse 104a, when the user clicks the mouse 104a, a sixth path P6 is constructed between the first element A and the fourth element D. In the same way, the seventh path P7 between the second element B and the fifth element E is constructed, and the eighth path P8 between the third element C and the fifth element E is constructed.

Therefore, the first, third, and fourth paths P1, P3, and P4 are deleted from the automatic insertion path of FIG. 4, so that an intermediate automatic insertion path as shown in FIG. 6 is constructed. Then, the sixth, seventh and eighth paths P6, P7 and P8 are generated from the intermediate automatic interpolation path shown in FIG. 6, so that the corrected automatic interpolation path as shown in FIG. 8 is constructed.

In step S107, the control section 106 controls the memory 108 to store therein the corrected automatic insertion path required to insert the electronic component into the PCB 201a.

In step S108 , the control section 106 reads out the correction path stored in the memory 110 .

In step S109, the control section 106 judges whether or not all paths of the corrected paths are connected based on the read corrected automatic insertion paths. At this time, referring to FIG. 9 , when a value other than "-1" is assigned to the left or right of each element, it is determined that all paths of the correction paths are connected. Alternatively, when "-1" is assigned to the left and right sides of each element, it is determined that any of the corrected automatic insertion paths are not connected to each other.

As a result of the judgment in step S109, when it is judged that any of the corrected automatically inserted paths is not connected, the control section 106 controls the monitor 110 to display an "error" message on the monitor (step S110). And, the procedure returns to step S106. Or, when it is judged in step S109 that all the paths of the correction path are connected, the user selects the path judgment button on the menu 203 by the operation of the mouse 108a or the keyboard 104b, so as to add the path judgment selection signal to the control section 106 (step S111 ).

Therefore, the control section 106 determines that the correction path is a desired automatic insertion path in response to the path decision selection signal from the mouse 104a or the keyboard 104b, and controls the monitor 110 to display a "path decision message" thereon (step S112) .

When the user inputs the file name for storing the desired automatic insertion path through the operation of the keyboard 104b, the control section 106 receives the file name for storing the desired automatic insertion path from the keyboard 104b (step S113).

In step S114, the control section 106 generates a numerical control (NC) program in accordance with the data format of each automatic insertion route device so as to process a desired automatic insertion route. The numerical control program is supplied to the memory 108 .

In step S115, the control section 106 controls the memory 108 to store the numerical control program in the received file name of the desired automatic insertion path, and the entire program is completed.

As described above, according to the present invention, the automatic insertion route regarding the electronic components to be inserted into the printed circuit board can be corrected to a desired automatic insertion route intended by the user.

While the invention has been particularly shown and described with reference to particular embodiments thereof, it will be understood that various changes in form and details may be made by persons skilled in the art without departing from the spirit and spirit of the invention as defined by the appended claims. scope.
