[0027] In modern electronic devices, liquid crystal displays (LCDs) are widely used due to their characteristics such as being thin, light, and low power consumption. The core part of an LCD is a liquid crystal module (LCM), and the flexible printed circuit board (FPC) is one of the key components connecting the LCM and the main board. In traditional FPC assembly processes, multiple FPCs are often pre - assembled on a large board, that is, multiple FPCs are connected to the large board, and the FPCs and the large board are connected by point connections. Then, during the LCM assembly stage, workers manually peel off the FPCs and then connect them to the LCM. However, the manual peeling speed is slow, not only with a high labor cost but also unable to meet the requirements of automated production.
[0028] The present utility model proposes a tearing mechanism.
[0029] Please refer to Figure 1 、 Figure 2 and Figure 3 In an embodiment of the present utility model, the tearing mechanism includes:
[0030] A carrier table 200 for carrying a product 110, and a film body 111 is provided on the surface of the product 110;
[0031] A blowing assembly 400 for blowing air towards the film body 111;
[0032] A driving structure 300; and
[0033] A clamping assembly 500, and the driving structure 300 is drivingly connected to the clamping assembly 500 to enable the clamping assembly 500 to clamp the film body 111.
[0034] In some embodiments, the tearing mechanism further includes a base 100, and the carrier table 200 is disposed on the base 100.
[0035] In the technical solution of the present utility model, a carrier 200 is placed on a base 100. The carrier 200 is used to carry a product 110. A driving structure 300 drives a blowing assembly 400 and a clamping assembly 500 to move, adjusts the blowing direction of the blowing port of the blowing assembly 400, so that the blowing direction faces the film body 111 to be torn off on the product 110. The film body 111 on the product 110 is point-connected to the product 110, that is, the unconnected part of the film body 111 is a warping angle. By adjusting the blowing direction of the blowing assembly 400 to make it blow towards the warping angle position, under the action of the air flow, the film body 111 warps up, breaks away from the plane of the product 110, and reaches the height of the output end of the clamping assembly 500. The clamping assembly 500 clamps the warping angle that warps up, serves as a leverage point for tearing off the film body 111, and the driving structure 300 drives the clamping assembly 500 to move to peel off the film body 111 on the product 110. At this time, the torn-off film body 111 is used for the next process, and the driving structure 300 drives the blowing assembly 400 and the clamping assembly 500 to move to the position of the next film body 111 to be torn off for tearing. Compared with manual peeling of the film body 111, the manual participation is reduced, the automation ability of the operation station is improved, and the processing efficiency is increased.
[0036] Specifically, the carrier 200 serves as a carrying main body and is used to place the product 110. The carrier 200 can be in a plate-like structure or a table-like structure, and the shape is not limited as long as the upper part of the carrier 200 is a horizontal plane for placing the product 110. A plurality of film bodies 111 are installed on the product 110 at intervals. A plurality of through holes having the same shape as the film bodies 111 are provided on the product 110. The film bodies 111 are in the through holes and are point-connected to the product 110 at the edges. The unconnected part of the film bodies 111 and the product 110 is used as the warping angle. The direction of the blowing assembly 400 is adjusted, and the blowing port corresponds to the warping angle. The warping angle is warped up by the air flow to facilitate clamping by the clamping assembly 500.
[0037] Please refer to Figure 3, in the embodiment of the present utility model, the clamping assembly 500 includes a first driving member 510 and two clamping members 520. The first driving member 510 drives the two clamping members 520 to approach each other to clamp the film body 111 or drives the two clamping members 520 to move away from each other. The first driving member 510 of the clamping assembly 500 is connected to the driving structure 300. The first driving member 510 uses a cylinder, and the cylinder drives the two clamping members 520 to approach each other or move away from each other. After the blowing assembly 400 blows up the warping angle of the film body 111, the first driving member 510 drives the two clamping members 520 to approach each other until the warping angle is clamped. The driving structure 300 drives the first driving member 510 of the clamping assembly 500 to move until the film body 111 is torn off by using the clamped warping angle as a leverage point. After reaching the next process, the first driving member 510 drives the two clamping members 520 to move away from each other to release the film body 111. When the film body 111 needs to be torn off again, the driving structure 300 drives the clamping assembly 500 and the blowing assembly 400 to move to the next film body 111 and repeat the above actions to complete the tearing of the film body 111.
[0038] Please refer to Figure 3 , in the embodiment of the present utility model, a buffer portion 530 is provided at one end of the clamping member 520 close to the product 110.
[0039] Specifically, a buffer portion 530 is provided on the opposite side of the two clamping members 520. When the film body 111 is clamped by the clamping members 520, it can be buffered to prevent damage to the film body 111 during the clamping process and affect the processing quality. The buffer portion 530 can use buffer rubber, which has certain wear resistance and high elasticity, so that it deforms to a certain extent during the clamping process to prevent the film body 111 from being clamped.
[0040] Please refer to Figure 3 , in the embodiment of the present utility model, the tearing mechanism further includes a detection sensor 600, and the detection sensor 600 is arranged on the clamping assembly 500.
[0041] Specifically, the detection sensor 600 is installed on one of the clamping members 520, and the sensing end of the detection sensor 600 is located on the side of the clamping member 520 for contacting the film body 111. The driving structure 300 drives the clamping assembly 500 to move above the film body 111. When the blowing assembly 400 blows up the warping angle, the warping angle just warps up between the two clamping members 520. At this time, the detection sensor 600 detects the warping angle. By setting the controller to receive the signal of the detection sensor 600 and transmit the signal to the driving structure 300 and the first driving member 510 of the clamping assembly 500, the first driving member 510 drives the two clamping members 520 to approach each other to clamp the film body 111, and the driving structure 300 drives the clamping assembly 500 to move to tear the film body 111 from the product 110. The detection sensor 600 can adopt an optical fiber sensing head. When the warping angle warps up between the two clamping members 520, the optical fiber sensing head detects the change of the optical signal, converts it into an electrical signal, and controls the clamping assembly 500 through the controller to realize the automatic judgment of the clamping process.
[0042] Please refer to Figure 3 , in the embodiment of the present utility model, the blowing assembly 400 is rotatably connected to the driving structure 300 so as to adjust the blowing direction of the blowing assembly 400 and facilitate blowing up the warping angle.
[0043] In another embodiment, the blowing assembly 400 includes a blow pipe 410 and a gas source. One end of the blow pipe 410 is connected to the gas source, and the other end faces the film body 111. The blow pipe 410 is rotatably connected to the driving structure 300.
[0044] Specifically, the blow pipe 410 is rotatably installed on the driving structure 300 through a clamping block 420. When the driving structure 300 drives the clamping assembly 500 and the blowing assembly 400 to move to the position of the film body 111 to be torn, by manually rotating the blow pipe 410 and adjusting the blowing direction of the blow pipe 410 to make it correspond to the position of the warping angle, the gas source is connected, and the air flow passes through the blow pipe 410 to blow up the warping angle, facilitating the tearing of the film body 111.

[0046] Specifically, the pressing assembly 700 is arranged on the bearing table 200 to press the product 110 onto the bearing table 200.

[0050] Specifically, the pressing plate 710 is arranged on the bearing platform 200, and the second driving member 720 drives the pressing plate 710 to move in the first direction, that is, the vertical direction, which means lifting and lowering relative to the bearing platform 200, so as to press both sides of the product 110 on the bearing platform 200, preventing the product 110 from moving during the tearing process and damaging the film body 111. Among them, the second driving member 720 is driven by a linear driving member such as a cylinder, a hydraulic cylinder or an electric telescopic rod.

Among them, the pressure bar 730 can be made of rubber but is not limited to rubber and other structures with certain elasticity.
[0053] In another embodiment, the pressing assembly 700 further includes a guide shaft 740 and a sleeve 750.

[0054] Specifically, please refer to Figure 4 , the guide shaft 740 is arranged at the bottom of the pressing plate 710 and passes through the bearing platform 200. When the second driving member 720 drives the pressing plate 710 to lift and lower, the pressing plate 710 moves along the guide shaft 740 through the sleeve 750, ensuring that the moving process does not deviate and improving the stability of the movement.
