Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile production, and in particular to a method for rapidly converting signals of automobile part molds based on machine tool interface electrical boxes. BACKGROUND

[0002] Automobile stamping line production automation and informatization have been widely used in major vehicle manufacturers, and the demand for automobile product individualization is also increasing. The diversity of part states, such as electronic rearview mirrors and ordinary rearview mirrors on front doors, requires quick production switching during the production process to ensure accurate automatic identification of mold information by the production line.

[0003] 1) Stamping part mold replacement: a set of molds or a mechanism needs to be switched to change the state of the part.

[0004] 2) Full sequence mold preparation: two or more sets of electrical box interfaces are needed to replace the corresponding electrical box interfaces (such as the existing mold and machine tool interface electrical box shown in FIG. Figure 1 ).

[0005] As can be seen, the electrical box interface of the full sequence mold has the disadvantages of multiple line connections, high cost, and high failure rate. In particular, when replacing the part state, the corresponding electrical box interface needs to be replaced by plugging and unplugging, which is time-consuming and labor-intensive. SUMMARY

[0006] In view of the above, the present application aims to provide a method for rapidly converting signals of automobile part molds based on machine tool interface electrical boxes to solve the aforementioned technical problems.

[0007] The technical solution adopted by the present application is as follows:

[0008] The present application provides a method for rapidly converting signals of automobile part molds based on machine tool interface electrical boxes, which includes:

[0009] Numbering the wiring holes of the electrical box and setting the wiring definitions corresponding to the wiring holes of different serial numbers;

[0010] According to the wiring definitions, the corresponding relationship between the wiring holes and the molds is established, and one end of the part cable is connected in the corresponding wiring hole based on the corresponding relationship;

[0011] The other end of the part cable is connected to the original machine main circuit through a rotary switch, wherein the rotary switch has a common end and a plurality of selection ends;

[0012] When the part mold needs to be switched, the rotary switch is operated to select the corresponding required mold.

[0013] In at least one possible implementation, the establishment of the corresponding relationship between the wiring holes and the molds includes:

[0014] Associate the part mold ID number with the part code;

[0015] Associate the part code with the serial number of the corresponding wiring hole of the part cable.

[0016] In at least one possible implementation, one end of the component cable connected based on the correspondence includes: connecting one end of multiple component cables with mold conversion requirements to adjacent wiring holes respectively.

[0017] In at least one possible implementation, the other end of the component cable is connected to the original main circuit via a rotary switch, comprising: multiple ends of the component cable leading out from the wiring hole are respectively connected to the selection terminal of the rotary switch, and the common terminal of the rotary switch is connected to the original main circuit.

[0018] In at least one possible implementation, numbering the wiring holes of the electrical box and defining the wiring definitions corresponding to the different serial numbers of the wiring holes includes:

[0019] Set the serial numbers of all the wiring holes in the electrical box in sequence, and define them sequentially according to different wiring function types by grouping adjacent wiring holes together.

[0020] In at least one of the possible implementations, the wiring function types include: power line, mold storage sensing line, part arrival sensing line, CAM arrival sensing line, part line, process line, and spare line.

[0021] Compared with existing technologies, the main design concept of this invention lies in addressing the diverse needs of different automotive product types by adding a set of rotary switches and redefining the wiring method to achieve rapid signal conversion in the electrical box. Specifically, the wiring holes of the electrical box are numbered, and wiring definitions are set for different serial numbers of the wiring holes. Based on the wiring definitions, a correspondence between the wiring holes and the molds is established, and one end of the component cable is connected to the corresponding wiring hole based on the correspondence.

[0027] This invention proposes an embodiment of a method for rapid signal conversion of automotive part molds based on a machine tool interface electrical box, specifically including:

[0028] Step S1: Number the wiring holes of the electrical box and set the wiring definitions corresponding to the wiring holes with different serial numbers;

[0029] by Figure 2 In the illustrated 32-hole electrical box embodiment, the wiring holes are numbered sequentially and grouped together by adjacent holes, and defined in an orderly manner according to different wiring function types. The wiring function types mentioned here include: power lines, mold storage sensor lines, part arrival sensor lines, CAM arrival sensor lines, part lines, process lines, and spare lines. Combined with... Figure 2 Example:

[0030] Pins 1 and 2 are used to connect the power cord: pin 1 is for 24V DC (input), pin 2 is for 0V DC (input);

[0031] Holes 3-6 are used to connect the induction wire for storing the mold;

[0032] Holes 7-10 are used to connect the part positioning sensing wire;

[0033] Holes 11 and 12 are used to connect the CAM positioning sensor line;

[0034] Holes 13-21 are used to connect part wires: corresponding to part codes 1-9;

[0035] Holes 22-24 are used to connect process lines: corresponding to process codes 1-3;

[0036] Holes 25-32 are used to connect spare cables.

[0037] Here, to facilitate the explanation later on how to achieve rapid signal conversion in the electrical box when the mold is changed, the correspondence between holes 13-21 and part codes in the previous example is illustrated in the following table for reference:

[0038] Step S2: Based on the wiring definition, establish the correspondence between the wiring holes and the mold, and connect one end of the part cable to the corresponding wiring hole based on the correspondence; in the production site, the mold ID number and the part code have a corresponding relationship, as shown below:

[0039] Based on the above description, the front cover outer panel can exist in three states. During the production process, there is a need to switch the molds corresponding to the three states (the mold ID number also needs to be switched accordingly).

[0040] Step S3: The other end of the component cable is connected to the original main circuit via a rotary switch; wherein the rotary switch has a common terminal and several selection terminals;

[0041] For the front cover outer panel mold in the above example, the wiring operation is as follows:

[0042] Holes 13, 14, and 15 are used to lead connecting wires to the rotary switch (box). The rotary switch has a common terminal connected to the main circuit and several select terminals. The aforementioned connecting wires are then connected to the select terminals respectively. Figure 3 And the following table:

[0043]

[0044] Step S4: When it is necessary to switch part molds, operate the rotary switch to select the corresponding required mold.

[0045] As described in the above embodiments, when there is a need to change the mold during the production process, a quick switching operation can be achieved simply by operating the knob switch to select the corresponding required part. This can save on spare parts costs and reduce downtime during the production process.

[0046] In summary, the main design concept of this invention lies in achieving rapid signal conversion of the electrical box by adding a set of rotary switches and redefining the wiring method to address the differences in requirements among various automotive product types. Specifically, the wiring holes of the electrical box are numbered, and wiring definitions are set for different serial numbers of the wiring holes. Based on the wiring definitions, a correspondence between the wiring holes and the molds is established, and one end of the component cable is connected to the corresponding wiring hole based on the correspondence. The other end of the component cable is connected to the original main circuit through the rotary switch. The rotary switch has a common terminal and several selection terminals. When it is necessary to switch component molds, the rotary switch is operated to select the corresponding mold. The electrical box wiring scheme proposed in this invention can significantly reduce the number of molds and electrical boxes used, thereby effectively reducing costs, improving mold conversion efficiency, and also reducing the failure rate.
