[0022] Referring to Figure 1 , the cover plate and display screen special-shaped fitting jig 1 in an embodiment of the present utility model includes a display screen groove 10, a cover plate groove 20, a clearance groove 21, and a pick-and-place groove 30. The display screen groove 10 is provided with a display screen FPC groove 11 and a handle tearing clearance groove 12 to avoid the display screen FPC 41 bound to the special-shaped display screen 40 to be fitted stored in the display screen groove 10 and the handle 42 for tearing the protective film on the back of the special-shaped display screen 1. The display screen groove 10 is further provided with a suction groove 13, and the suction groove 13 is provided with a suction hole 131. The suction hole 131 is connected to an air intake hole 132 to connect an external air pipe. The cover plate groove 20 stores the special-shaped cover plate 50 with OCA already fitted, and multiple elastic columns 22 are provided in the cover plate groove 20.

[0023] In this way, in the process of fitting the special-shaped cover plate 50 and the special-shaped display screen 40, first clean the jig, connect the external air pipe, place the special-shaped display screen 40 face down in the display screen groove 10, and align the display screen 40 with the display screen FPC 41 in the display screen FPC groove 11. Start the suction hole 131 to suck air, adsorb and position the special-shaped display screen 40. Then, peel off the release film in the OCA of the special-shaped cover plate 50 with OCA already fitted, and at the same time peel off the front protective film of the special-shaped display screen 40 stored in the jig. Then place the special-shaped cover plate 50 with the OCA side already fitted face down on the top of the elastic column 22. After the special-shaped cover plate 50 is balanced on the top of the elastic column 22, press the cover plate 50 down to complete the entire fitting process.

[0024] In this embodiment, the above-mentioned jig 1 is preferably made of red padauk by CNC machining.

[0025] Referring to Figure 2 , in this embodiment, the suction groove 13 is preferably a circular groove, and there is 1 suction hole 131. When the suction hole 131 sucks air, the gas in the suction groove 13 is discharged, thereby adsorbing the display screen 40. Using the circular suction groove 13 can ensure that the suction force is evenly distributed on the entire contact surface, and the uniform suction force distribution helps to improve the stability of the workpiece on the jig 1.

[0026] In this embodiment, the air intake hole 132 is provided on the side of the jig.

[0027] It should be noted that the above setting position of the air intake hole 132 does not limit the present utility model.

[0028] In this embodiment, there are three clearance slots 21 for avoiding the corners of the cover plate 50 during fitting, reducing the contact and collision between the corners of the cover plate 50 and the jig 1 when the cover plate 50 is fitted to the display screen 40.

[0029] Referring to Figure 3 , in another embodiment, the elastic columns 22 are made of PVC spring columns and there are 3 of them, evenly distributed in a triangle in the cover plate groove 20. The heights of these 3 PVC elastic columns are the same, and the height of each elastic column is half of the depth of the cover plate groove 20. With this design, the cover plate 50 with OCA glue already attached is placed on top of the PVC spring columns 22 when not fitted, so that the OCA glue on the cover plate does not come into contact with the display screen 40 first. After the cover plate 50 is successfully positioned on top of the three PVC spring columns 22, the cover plate 50 is then pressed down to complete the fitting.

[0030] During use, after the special-shaped display screen 40 is adsorbed and positioned, the cover plate 50 with OCA glue attached is peeled off the release film in the OCA glue, and at the same time, the front protective film of the display screen stored in the jig is peeled off. Then, the cover plate 50 with the OCA surface attached is placed face down in the cover plate groove 20 and on top of the three PVC spring columns 22. After the cover plate 50 is balanced on top of the three columns, the cover plate is pressed down to complete the entire fitting process.

[0031] In this embodiment, there are 2 pick-and-place slots 30 for manually picking and placing the display screen 40 and the cover plate 50 before and after fitting. The two pick-and-place slots 30 can be used to store the display screen 40 and the cover plate 50 to be fitted, as well as the finished products to be taken out after fitting respectively. Such a design makes the pick-and-place process more orderly, avoids confusion and errors, helps to optimize the production process, and improves product quality and production efficiency.

[0032] As described above, through the design of the suction slots 13 in the display screen groove 10 of the jig, the adsorption and positioning of the display screen are realized when the suction holes 131 in the suction slots 13 are activated to suck air. By arranging multiple elastic columns 22 in the cover plate groove 20, the OCA glue on the cover plate 50 is prevented from coming into contact with the display screen 40 first. The cover plate 50 with the OCA glue attached is first positioned and balanced on the elastic columns 22 and then fitted to the display screen 40, which can better avoid the occurrence of misalignment.

[0033] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
