[0016] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0017] Example

[0018] In order to solve the above technical problems, this embodiment provides a large-size touch screen bonding fixture, such as Figure 1-2 As shown, it includes a base 10, a placement groove 11 is opened on the upper surface of the base 10, and the placement groove 11 is used to accommodate the liquid crystal module. A number of support blocks 20 are symmetrically arranged on the outer periphery of the base 10 located at the placement groove 11. The support blocks 20 are connected to the base 10 through elastic components 40. The touch screen is placed on the support blocks 20. The support blocks 20 and the touch screen are supported so that the touch screen is suspended above the liquid crystal module. Then, by pressing down the support blocks 20 and the touch screen, the touch screen is fitted with the liquid crystal module on the placement groove 11. Each support block 20 is connected to the base 10 through an elastic component 40, and the elastic component 40 plays a buffering role during the fitting process. At the same time, a guide rod 30 is fixed on one side of the support block 20, and a guide sleeve 31 is embedded on the base 10. The guide rod 30 is inserted into the guide sleeve 31. The guide rod 30 and the guide sleeve 31 are guided and cooperated so that the support block 20 and the touch screen descend smoothly during the fitting process, ensuring that the large-size touch screen is evenly and fully fitted with the liquid crystal module, reducing the problem of poor display after fitting, and improving the fitting quality.

[0019] Further, such as Figure 3 As shown, the support block 20 has an L-shaped positioning groove 21 on one side facing the placement slot 11. The L-shaped positioning groove 21 is used to limit the four sides of the touch screen, and multiple support blocks 20 are distributed around the placement slot 11. For example, four support blocks 20 are distributed at the four corners of the placement slot 11 to limit the four corners of the touch screen. Alternatively, four support blocks 20 can be distributed along the long and short sides of the placement slot 11 to further limit the four sides of the touch screen. This ensures the accurate positioning of the touch screen and the LCD module, improving the accuracy of the fit.

[0020] Furthermore, a receiving groove 12 is provided on the base 10 at a position corresponding to the support block 20. The elastic component 40 includes a support column 41 movably provided in the receiving groove 12, and an elastic member 42 sleeved on the outer periphery of the support column 41. The support column 41 is provided on the bottom surface of the support block 20, and one end of the elastic member 42 abuts against the bottom surface of the support block 20, and the other end abuts against the bottom of the receiving groove 12. The elastic member 42 cushions the movement of the support block 20 and the touch screen to prevent the touch screen from colliding with the liquid crystal module due to excessive downward pressure and thus being damaged. It should be noted that the bonding jig of this embodiment can be placed in a bonding device for automatic bonding, or the bonding jig can be used as an auxiliary tool and the bonding process can be performed by manual pressing. This embodiment does not limit the bonding method.

[0021] Specifically, a through slot 13 is formed in the base 10, and a guide sleeve 31 is inserted into the through slot 13. The guide sleeve 31 is detachably connected to the base 10 via a locking member. For example, the locking member can be a screw. The guide rod 30 slides with the guide sleeve 31. The guide rod 30 is fixed to one side of the support block 20. During the bonding process, the support block 20 descends, driving the guide rod 30 downward. The guide rod 30 then slides within the guide sleeve 31. The guide sleeve 31 guides the rise and fall of the guide rod 30, ensuring balanced rise and fall of each support block 20. This prevents tilting of the touch screen during bonding of a large touch screen, which could affect bonding quality and thus prevent poor display after bonding the touch screen to the LCD module.

[0022] Furthermore, sink grooves 14 are provided on opposite sides of the placement groove 11. When placing or removing the liquid crystal module by hand or a robot, the sink grooves 14 serve as a space avoidance, making it convenient for the hand or the robot to place or remove the liquid crystal module on the placement groove 11.

[0023] Furthermore, after the liquid crystal module is placed in the placement groove 11, in order to ensure the position of the liquid crystal module is stable during the bonding process, in some embodiments, such as Figure 4 As shown, a plurality of adsorption holes 15 are evenly provided on the bottom surface of the placement groove 11, and ventilation holes 16 connected to the adsorption holes 15 are provided on the side of the base 10. By connecting the ventilation holes 16 to the negative pressure generator, and then generating appropriate negative pressure, the liquid crystal module is fixed in the placement groove 11, ensuring that the liquid crystal module will not be displaced during the bonding process, thereby improving the bonding accuracy.

[0024] Furthermore, the bonding jig of this embodiment can be placed in a bonding device for automatic bonding. In some embodiments, a mounting plate 17 is formed on one side of the base 10, and the mounting plate 17 can be used for positioning and mounting so that the base 10 is fixed in the bonding device.

[0025] To summarize, the present application scheme is to provide a placement groove on the upper surface of the base, the placement groove is used to accommodate the liquid crystal module, and a number of support blocks are symmetrically arranged on the outer periphery of the base located at the placement groove, the support blocks are connected to the base through elastic components, the touch screen is placed on the support blocks, and the touch screen is supported by the support blocks so that the touch screen is suspended above the liquid crystal module, and then the support blocks and the touch screen are pressed down so that the touch screen is fitted with the liquid crystal module on the placement groove, each support block is connected to the base through an elastic component, and then the elastic component plays a buffering role during the fitting process, and at the same time, a guide rod is fixed on one side of the support block, and a guide sleeve is embedded on the base, the guide rod is inserted into the guide sleeve, and the guide rod and the guide sleeve are guided and cooperated so that the support block and the touch screen descend smoothly during the fitting process, ensuring that the large-size touch screen and the liquid crystal module are evenly and fully fitted, reducing the problem of poor display after fitting, and improving the fitting quality.
