Abstract
Description
Technical Field
[0001] This utility model relates to the field of polarizer processing technology, specifically to an automatic film receiving device for a polarizer die punching machine. Background Technology
[0002] Polarizing films have a wide range of applications, primarily functioning to filter out stray light, enhance visual acuity, improve color contrast, and maximize visual comfort, allowing the eyes to see objects clearly. Polarizing film punching machines use a die to cut polarizing films of the required size through upper and lower punching. However, during the punching process, because the surface of the polarizing film is very smooth, under the pressure of the die, the polarizing film easily adheres to the bottom wall of the die cavity, making it difficult to automatically collect the polarizing film and requiring manual intervention to remove it. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic film receiving device for a polarizer die punching machine, thereby solving the deficiencies of the prior art.
[0004] The purpose of this utility model is achieved through the following technical solution: an automatic film receiving device for a polarizing film die punching machine, comprising a stamping platform, a stamping groove on the top surface of the stamping platform, a stamping die above the stamping platform, the stamping die having a degree of freedom to move along the height direction of the stamping platform, a cavity inside the stamping platform, the stamping groove communicating with the cavity, a support plate slidably disposed inside the cavity, the support plate having a degree of freedom to move along the horizontal direction, an air cavity inside the support plate, and multiple air blowing holes on the top surface of the support plate communicating with the air cavity.
[0005] Furthermore, the support plate is connected to an air pump via an air pipe, and the air pipe is connected to the air chamber.
[0006] Furthermore, a push cylinder is horizontally installed at one end of the stamping platform, and the telescopic shaft of the push cylinder moves into the cavity to connect to the support plate.
[0007] Furthermore, the bottom of the stamping platform is provided with a feeding port, which is connected to the cavity.
[0008] Furthermore, a support platform is provided below the stamping platform, a limiting cone is fixed at the top of the support platform, a limiting hole is opened at the bottom of the receiving box, the limiting cone is adapted to the limiting hole, and the unloading port is located directly above the top opening of the receiving box.
[0009] Furthermore, the bottom of the stamping platform is fixed with multiple support columns, and the bottom of each support column is fixed with a flange, which is connected to the support platform by bolts.
[0010] Furthermore, a stamping frame is provided on one side of the stamping platform, and a stamping cylinder is vertically mounted on the stamping frame. The telescopic shaft of the stamping cylinder is connected to a stamping shaft, and the flange at the end of the stamping shaft away from the stamping cylinder is connected to the stamping die.
[0011] Furthermore, the stamping die has an air hole in the middle, and the top of the stamping die has an air inlet that communicates with the air hole. The air inlet is connected to the air pump through a pipe.
[0012] The beneficial effects of this utility model are:
[0013] The polarizer is placed in the stamping groove and supported by the support plate. The stamping die presses the polarizer onto the support plate to complete the stamping and forming of the polarizer. Gas is blown out through the air hole of the support plate to break the negative pressure environment between the support plate and the polarizer, so that the polarizer is detached from the support plate. This ensures that the polarizer can be automatically collected without being obstructed. Attached Figure Description

Detailed Implementation
[0018] Example 1
[0019] like Figures 1 to 3As shown, an automatic film receiving device for a polarizing film die punching machine includes a punching platform 1, a punching groove 2 on the top surface of the punching platform 1, a punching die 3 above the punching platform 1, the punching die 3 having a degree of freedom to move along the height direction of the punching platform 1, a cavity 4 inside the punching platform 1, the punching groove 2 communicating with the cavity 4, a support plate 5 slidably disposed inside the cavity 4, the support plate 5 having a degree of freedom to move along the horizontal direction, an air chamber 6 inside the support plate 5, and multiple air blowing holes 7 on the top surface of the support plate 5. The air blowing hole 7 is connected to the air chamber 6. The support plate 5 is connected to the air pump through the air pipe. The air pipe is connected to the air chamber 6. The polarizer is placed in the stamping groove 2 and supported by the support plate 5. The stamping die 3 stamps on the support plate 5 to complete the stamping of the polarizer. Air is introduced into the air chamber 6 through the air pump. The air is blown out through the air blowing hole 7 on the support plate 5. The air breaks the negative pressure environment between the support plate 5 and the polarizer, causing the polarizer to detach from the support plate 5. This ensures that the polarizer's retraction action is not hindered and achieves the effect of automatic retraction.
[0020] Example 2
[0021] Based on Example 1, such as Figure 1 and Figure 3 As shown, a stamping frame 16 is provided on one side of the stamping platform 1. A stamping cylinder 17 is vertically installed on the stamping frame 16. The telescopic shaft of the stamping cylinder 17 is connected to a stamping shaft 18. The flange of the end of the stamping shaft 18 away from the stamping cylinder 17 is connected to the stamping die 3. The extension and retraction of the stamping cylinder 17 drives the stamping die 3 to move up and down, thereby completing the stamping and forming of the polarizer. An air hole 19 is provided in the middle of the stamping die 3. An air inlet 20 is provided at the top of the stamping die 3, which is connected to the air hole 19. The air inlet 20 is connected to an air pump through a pipe. In order to prevent the polarizer from sticking to the stamping die 3, before the stamping die 3 is removed from the stamping groove 2 after stamping, air is blown out through the air hole 19 to blow off the polarizer sticking to the stamping die 3, so that the polarizer does not stick to the stamping die 3 and the support plate 5, which facilitates the subsequent automatic film collection operation of the polarizer.
[0022] Example 3
[0023] Based on Example 2, such as Figure 1 and Figure 2As shown, a push cylinder 8 is horizontally installed at one end of the stamping platform 1. The telescopic shaft of the push cylinder 8 moves into the cavity 4 and connects to the support plate 5. A feeding port 9 is opened at the bottom of the stamping platform 1, which is connected to the cavity 4. A support platform 10 is set below the stamping platform 1. A limiting cone 11 is fixed at the top of the support platform 10. A limiting hole 13 is opened at the bottom of the take-up box 12, and the limiting cone 11 is adapted to the limiting hole 13. The feeding port 9 is located directly above the top opening of the take-up box 12. The support plate 5 is slidably set to facilitate the automatic feeding of polarizing film to complete the take-up operation. Specifically, the wound polarizing film is released through... The stamping groove 2 of the stamping platform 1 uses a stamping die 3 to stamp and form a polarizing film. After stamping out a polarizing film, the cylinder 8 is pushed to move the support plate 5, so that the support plate 5 moves to one side of the stamping groove 2, causing the polarizing film to separate from the support plate 5. This allows the polarizing film to fall from the stamping groove 2 into the unloading port 9, and finally from the unloading port 9 into the receiving box 12, achieving automatic film collection. Then, the support plate 5 returns to its original position and contacts the bottom of the stamping groove 2, and the polarizing material continues to be conveyed. The above process is repeated to stamp again, thereby achieving continuous stamping and forming. Each polarizing film formed can be automatically collected, improving stamping efficiency.
[0024] Example 4
[0025] Based on Embodiment 3, multiple support columns 14 are fixed to the bottom of the stamping platform 1, and a flange 15 is fixed to the bottom of the support column 14. The flange 15 is connected to the support platform 10 by bolts, so that the stamping platform 1 can be replaced. When it is necessary to stamp polarizers of different sizes and shapes, the corresponding stamping platform 1 is replaced. The stamping groove 2 on the stamping platform 1 matches the size and shape of the polarizer. At the same time, the stamping die 3 of the corresponding size and shape is replaced, so that polarizers of various sizes and shapes can be stamped.
