Description

A stamping die for FPC panel splitting Technical Field

[0001] This application relates to the field of mold technology, and more specifically, to a stamping die for FPC panel splitting. Background Technology

[0002] FPC is a printed circuit board made of flexible insulating substrate (mainly polyimide or polyester film), which has the characteristics of high wiring density, light weight, thin thickness and good flexibility.

[0003] In the production process of FPC products, the FPC product is usually placed on the lower platen of the stamping die. After the FPC product and the scrap are separated by the die, the FPC product is picked up by a suction cup and placed into the tray that carries the separated products. However, the above production method requires time to install and debug the suction cup every time the line is changed, which is time-consuming and labor-intensive, increases labor costs, and affects production efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a stamping die for FPC depaneling, which can complete the loading and unloading of FPC products after the stamping of the FPC products is completed, so that only the die needs to be installed each time the line is changed, and there is no need to install and debug the suction cup, thereby improving the work efficiency.

[0005] This application provides a stamping die for FPC splitting, adopting the following technical solution:

[0006] A stamping die for FPC separation includes an upper die base and a lower die base. The upper die base is provided with a female die and a receiving groove. An inner stripper is provided in the receiving groove. The lower die base is provided with a male die and a stripper plate. The stripper plate is disposed on the male die and a carrier is disposed on the stripper plate. The carrier is located below the inner stripper.

[0007] Preferably, the lower die base is provided with a punch holder, the punch holder is located below the stripper plate, a plurality of elastic elements are provided between the punch holder and the stripper plate, a punch is provided on the punch holder, the punch penetrates the stripper plate and extends above the stripper plate, and a guide groove is provided on the female die.

[0008] Preferably, there are two of each of the punch and the guide groove, and they are arranged in a one-to-one correspondence.

[0009] Preferably, the elastic element is a spring.

[0010] Preferably, the inner peeler is a suction cup.

[0011] Preferably, the punch holder is fixed to the lower die base by bolts.

[0012] Preferably, the carrier is fixed to the stripper plate by bolts.

[0013] Preferably, the female mold is fixed to the upper mold base by bolts.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] This application incorporates an internal peeler on the female mold. After the FPC product is stamped, the female mold leaves the male mold, and the internal peeler picks up the FPC product. The female mold moves to a set position and stops, moving the tray under the FPC product. The internal peeler then places the FPC product inside the tray, thus enabling the picking and placing of FPC products. This eliminates the need to install the mold each time the production line is changed, instead of installing and adjusting the suction cup, thereby improving operational efficiency.

[0027] Example

[0028] As shown in Figures 1 and 2, the FPC separation stamping die described in this application includes an upper die base 1 and a lower die base 2. The upper die base 1 is provided with a female die 3, and the female die 3 is provided with a receiving groove 4. An inner stripper 5 is provided in the receiving groove 4. The lower die base 2 is provided with a male die 6 and a stripper plate 7. The stripper plate 7 is provided on the male die 6, and a carrier 8 is provided on the stripper plate 7. The carrier 8 is located below the inner stripper 5.

[0029] In use, the FPC product 13 is placed on the carrier 8 and stamped to separate the FPC product 13 from the waste material. After the FPC product 13 is stamped, the female mold 3 leaves the male mold 6, and the inner peeler 5 picks up the FPC product 13. The female mold 3 moves to the set position and stops, and moves the tray under the FPC product 13. The inner peeler 5 places the FPC product 13 into the inside of the tray, realizing the picking and placing of the FPC product 13. Thus, only the mold needs to be installed each time the line is changed, and there is no need to install and adjust the suction cup, which improves the work efficiency.

[0030] In this embodiment, a punch holder 9 is provided on the lower die base 2. The punch holder 9 is located below the stripper plate 7. Multiple elastic elements 12 are provided between the punch holder 9 and the stripper plate 7. When the FPC product 13 is stamped, the elastic elements 12 are compressed. As the female die 3 moves away from the male die 6, the elastic elements 12 rebound, which facilitates the stripper plate 7 to return to its initial position. A punch 10 is provided on the punch holder 9. The punch 10 penetrates the stripper plate 7 and extends above the stripper plate 7. A guide groove 11 is provided on the female die 3. By setting the punch 10 and the guide groove 11, the female die 3 and the male die 6 can be accurately aligned to ensure the effect of use.

[0031] In this embodiment, there are two punches 10 and two guide grooves 11, and they are arranged in a one-to-one correspondence. The arrangement of punches 10 and guide grooves 11 can ensure the stamping effect.

[0032] In this embodiment, the elastic element 12 is a spring, which has the advantages of simple and reliable structure, low cost and high adaptability.

[0033] In this embodiment, the inner peeler 5 is a suction cup. The suction cup can achieve efficient adsorption through a simple principle and will not damage the product surface.

[0034] In this embodiment, the punch holder 9 is fixed to the lower die base 2 by bolts. The bolt fixing method facilitates the assembly and disassembly of the punch holder 9 and the lower die base 2.

[0035] In this embodiment, the carrier 8 is fixed to the stripper plate 7 by bolts, and the bolt fixing method facilitates the replacement of the carrier 8.

[0036] In this embodiment, the female mold 3 is fixed to the upper mold base 1 by bolts. The bolt fixing method facilitates the assembly and disassembly of the female mold 3 and the upper mold base 1.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
