Description

Technical Field

[0001] The utility model relates to a fixture for attaching a protective film to a TP, in particular to a fixture for attaching double-sided protective films to a vehicle-mounted TP. Background Technique

[0002] For vehicle-mounted TP models with a small quantity, the attachment of the protective film requires machine adjustment, and the machine adjustment time is generally 2 - 4 hours. The machine adjustment process will cause some defective losses of the adjusted products. Therefore, fixtures are mostly used to complete the attachment of the protective film, which helps to reduce the machine adjustment time. Moreover, the use of fixtures makes the attachment process more standardized and streamlined. This optimization helps to reduce the chaos and errors that may occur during the machine adjustment process, thereby further shortening the machine adjustment time and improving the product yield and attachment efficiency.

[0003] When attaching double-sided protective films to a vehicle-mounted TP, since the TP-FPC is not centered and bonded to the TP, two fixtures are required to complete the attachment. When the batch size is small, it increases the mold development cost, and the double-fixture fitting operation has relatively low fitting yield and efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a fixture that can simultaneously attach double-sided protective films to a vehicle-mounted TP within the same fixture, further shortening the machine adjustment time and improving the fitting yield and efficiency.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A fixture for attaching double-sided protective films to a vehicle-mounted TP. TP blocks are arranged around the fixture to position the TP. The fixture is provided with a protective film groove for storing the front and back protective films for positioning the TP. The inner edge of the protective film groove is recessed to form a material taking and placing groove and a second clearance groove. The material taking and placing groove is used for taking and placing the TP, and the second clearance groove is used for taking and placing the TP and for the TP to avoid the FPC bonded to the TP when attaching the back protective film. The fixture is also provided with a first clearance groove on the same side surface as the second clearance groove. The first clearance groove is used for the TP to avoid the FPC bonded to the TP when attaching the front protective film. The protective film groove is also provided with a protective film tearing handle groove and a suction hole. An air connection port is arranged on one side surface of the fixture, which is connected to the suction hole and externally connected to an air path. Thus, the TP can attach the front protective film in the protective film groove and then attach the back protective film, completing the attachment of the front and back protective films on one fixture simultaneously.

[0007] Further, 2 pieces of the TP blocks are arranged on each of the long side and the wide side of the fixture.

[0008] Further, the height of the TP block is three times the thickness of the TP, and a flexible pad is covered on the contact surface between the TP block and the TP.

[0009] Further, the sides of the pick-and-place slot and the second clearance slot close to the protective film slot are recessed inward by 3 mm. The second clearance slot not only clears the FPC of the TP binding but also serves the function of picking and placing the TP. Therefore, when the sides close to the protective film slot are recessed inward, when taking out the TP, the finger can touch the TP first and is not blocked by the fixture.

[0010] Further, there are multiple suction holes, which are gathered and linked to the air connection port.

[0011] Further, the suction hole matrix is arranged evenly in the protective film slot and the protective film tearing handle slot.

[0012] Further, when the back protective film is placed in the protective slot, the protective film clearance opening of the back protective film corresponds to and is close to the second clearance slot.

[0013] Further, the fixture is made of red padwood, and the peripheral projection of the fixture is a rectangle with rounded corners.

[0014] The fixture of the present utility model performs double-sided attachment of the front and back protective films of the TP through a protective film slot, reducing the number of molds used and further reducing the machine adjustment time; the suction holes in the same protective film slot suck and adsorb the front and back protective films, reducing the positioning difficulty and operation difficulty of attaching the front and back protective films. At the same time, the first and second clearance slots for attaching the front and back protective films are opened on the fixture, enabling the FPC of the TP binding to be effectively cleared within one fixture during the front and back attachment of the TP, thereby improving the attachment efficiency and the attachment yield rate.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] To solve the operational deficiencies caused by the fact that when attaching double-sided protective films to in-vehicle TP, since the FPC bound to the TP is not centered on the TP and two jigs are required to complete the attachment, refer to Figure 1 In the embodiment of the in-vehicle TP double-sided protective film jig of , a total of 8 TP clamping blocks 10 are arranged around the jig 1 for positioning the TP4. The jig is provided with a protective film groove 20 for storing and positioning the front and back protective films 2 and 3 of the TP. The inner edge of the protective film groove 20 is recessed to form a loading and unloading slot 11 for loading and unloading the TP and a second clearance slot 12 for taking and placing the TP and avoiding the FPC bound to the TP when attaching the back protective film. On the same side surface of the jig 1 as the second clearance slot 12, there is also a first clearance slot 13 for the TP4 to avoid the FPC5 bound to the TP4 when attaching the front protective film 2. The protective film groove 20 also has a protective film tearing handle groove 201 and a suction hole 202. One side surface of the jig 1 is provided with an air connection port 14, which is connected to the suction hole 202 and externally connected to an air circuit. Thus, the TP4 can attach the front protective film 2 in the protective film groove 20 and then attach the back protective film 3, and the attachment of the front and back protective films 2 and 3 of the TP4 can be completed simultaneously on one jig.

[0025] In one implementation of this embodiment, two TP clamping blocks 10 are provided on each of the long side and the wide side of the fixture 1. The height of the TP clamping blocks 10 is three times the thickness of the TP4, so that the TP4 to be attached can be clamped more stably. The TP clamping blocks 10 can be sleeved with flexible cushion sleeves or covered with flexible pads on the contact surface of the TP4 to protect the TP4.

[0026] In one implementation of this embodiment, the edges of the material loading and unloading groove 11 and the second clearance groove 12 close to the protective film groove 20 are each retracted inward by 3 mm. The second clearance groove 12 not only clears the FPC5 bound to the TP4 but also serves the function of loading and unloading the TP4. Therefore, when the edges close to the protective film groove 20 are retracted inward, when taking out the TP4, the finger can touch the TP4 first and is not blocked by the fixture.

[0027] In one implementation of this embodiment, there are multiple air suction holes 202, which are arranged in a matrix and evenly distributed in the protective film groove 20 and the protective film tearing handle groove 201, and are gathered and linked to the air connection port 14. In this way, when the front and back protective films 2 and 3 are placed in the protective film groove 20 and the air suction is started, the protective films 2 and 3 can be positioned and evenly adsorbed.

[0028] The fixture 1 of this embodiment is preferably made of red padwood, and the peripheral projection of the fixture 1 is a rectangle with rounded corners.

[0029] The process of using the fixture 1 of this embodiment for attachment is described as follows: Refer to Figure 2 , clean the fixture 1, connect the external trachea to the air connection port 14 of the fixture 1. Then, put the front protective film 2 into the protective film groove 20 in the fixture 1, and the tearing handle on the front protective film 2 corresponds to the protective film tearing handle groove 201 of the fixture.

And the FPC5 bound to the TP4 is placed corresponding to the first clearance groove 13 of the fixture and attached to the front protective film 2. After attachment, turn off the air suction. Refer to Figure 4 , after turning off the air suction, take out the TP semi-finished product with the front protective film 2 attached from the fixture 1, put the back protective film 3 into the protective film groove 20 in the fixture 1, the protective film tearing handle is docked with the protective film tearing handle groove 201 of the fixture, and the protective film clearance opening 31 of the back protective film 3 is close to the second clearance groove 12. Start the air suction to position and adsorb the back protective film 3. Refer to Figure 5 , peel off the back protective film of the TP semi-finished product with the front protective film 2 attached, and then place the TP semi-finished product with the non-protective film side down in the eight TP clamping blocks 10 of the fixture. And the FPC5 bound to the TP4 is placed corresponding to the second clearance groove 13 of the fixture 1 and attached to the back protective film 3. After attachment, turn off the air suction and take out the TP with the double-sided protective film attached.

[0030] In summary, the fixture of the present utility model performs double-sided attachment of the front and back protective films 2 and 3 of the TP through a protective film groove 20, reducing the number of molds used and further reducing the machine adjustment time; the suction holes 202 in the same protective film groove 20 suck and adsorb the front and back protective films 2 and 3, reducing the positioning difficulty and operation difficulty of attaching the front and back protective films 2 and 3. At the same time, the fixture 1 is provided with the first 14 and second clearance grooves 13 for attaching the front and back protective films, so that the FPC 5 bound to the TP 4 can be effectively cleared within a fixture during the attachment of the front and back of the TP, thereby improving the attachment efficiency and the attachment yield rate.
