[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] The present application embodiment provides a high-precision foam lamination jig, see Figure 1 , including a plate 10, the upper surface of which is recessed with a foam groove 11, which is in a closed frame shape. The foam groove 11 fixes the foam so that it does not shift, thereby improving the fitting accuracy and yield rate, and release films are provided on the upper and lower surfaces of the foam. The foam groove 11 is provided with an air suction hole 12, which is connected to an external suction device to form a negative pressure to suck the foam placed in the foam groove 11, further fix the foam, and facilitate tearing off the release film.

[0025] It should be noted that: a film tearing handle is provided on the release film on the surface of the foam. When the staff starts the suction device, the suction hole 12 sucks the foam, and the staff tears off the release film by tearing off the film tearing handle, so that the foam with the torn release film is adhered to the back of the cover plate, and the suction device sucks the foam through the suction hole 12. When removing the cover plate and the foam, the release film on the lower surface is torn off to improve the assembly efficiency of the cover plate and the casing.

[0026] For further information, see Figure 1 The air pipe port 20 is arranged on the side of the plate 10. This design can place the plate 10 flat, and then facilitate the cover plate to be close to the plate 10 and to be pasted with the foam. The air suction hole 12 is connected to the air pipe port 20, and the air pipe port 20 is connected to the external suction device.

[0027] In addition, the plate 10 has a foam limiting block 30 extending upward from the frame-shaped inner side of the foam groove 11, and the foam limiting block 30 further limits the foam in the foam groove 11, and then accurately adheres to the cover plate, thereby further improving the adhesion accuracy.

[0028] In one of the embodiments, a cover plate limiting assembly 40 is provided on the upper surface of the plate 10. The cover plate limiting assembly 40 includes a plurality of cover plate clamps. The cover plate clamps are evenly arranged around the upper surface of the plate 10. When the cover plate abuts against the foam in the plate 10, the cover plate clamps limit the position of the cover plate, so that the fitting position of the cover plate is accurately adhered to the foam, thereby further improving the fitting accuracy.

[0029] See also Figure 1 In order to facilitate loading and unloading, a first material taking groove 50 is provided on the upper surface of one side of the plate 10 along its lower surface, which makes it easy for the staff to unload or load the bonded cover plate from the jig. In addition, a second material taking groove 60 is provided on the upper surface of the plate 10 on the opposite side of the first material taking groove 50 along its lower surface, which makes the loading and unloading process more stable.

[0030] In order to facilitate the removal of the cover plate after the cover plate and the foam are bonded, a counterweight assembly is provided on the plate 10, so that the cover plate and the plate 10 can be easily separated during the blanking process. Specifically, the counterweight assembly includes two weight blocks, which are respectively clamped with the two sides of the plate 10, and the weight blocks are provided with limiting grooves. Both sides of the plate 10 are provided with limiting ribs, which are sleeved in the limiting grooves to connect the plate 10 and the weight blocks. This design enables the weight blocks and the plate 10 to be detachably connected, and when the plate 10 is damaged, there is no need to scrap the weight blocks at the same time.

[0031] In one embodiment, a handle is provided on the side of the plate 10 to facilitate the staff to move or carry the jig.

[0032] Also, see Figure 1The upper surface of the plate 10 is provided with an avoidance groove 70 along its lower surface to avoid the position of the film tearing handle, thereby facilitating the tearing off of the release film and improving the assembly efficiency.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
