[0030] In order to solve the technical problems existing in the manual lamination of touch panels, that is, product defects such as tilting and uneven edge spacing will be caused, which seriously affect the quality of the product. The present invention proposes a touch panel lamination assembly device, which can realize the following three functions: ① alignment calibration and suction locking of the keyboard frame, ② alignment calibration of the touch panel, and ③ promotion lamination of the touch panel.

[0031] See also Figure 1 and 2As shown, the touch panel assembly equipment is mainly composed of a distribution box 10 and a positioning panel 11. The positioning panel 11 is placed on the top plane of the distribution box 10, and is hollowed out with a vacuum suction cup assembly 13, a touch panel positioning cavity 14 and other working areas. At the same time, in order to facilitate the alignment of the assembly carrier (the keyboard frame 20 of the laptop computer is taken as an example in this embodiment), a set of limit blocks 12 are designed on a group of adjacent edges on the positioning panel 11, and a set of alignment components are designed on another group of adjacent edges. Through the work of the two sets of alignment components, the keyboard frame 20 can be temporarily fixed and limited on the positioning panel 11, and at the same time, it is ensured that the touch module 21 on the keyboard frame 20 is placed directly above the touch panel positioning cavity 14, which is convenient for the subsequent touch panel assembly. Since the touch panel has an instantaneous upward lifting force on the touch module 21 when the touch panel is assembled, in order to prevent the keyboard frame 20 from leaving its limit area, it is sucked and fixed by the vacuum suction cup assembly 13 to prevent it from moving, which is convenient for the assembly of the touch panel. The vacuum suction cup assembly 13 is connected to the vacuum generating device outside the distribution box 10 through a pipeline.

[0032] See also Figure 3 As shown, the alignment assembly is mainly composed of a positioning cylinder 31, a cylinder guide rod 32, a push plate 30 and a connecting plate 33. The positioning cylinder 31 is installed inside the distribution box 10. The cylinder guide rod 32 of the positioning cylinder 31 is connected to the push plate 30 through the connecting plate 33, so that the push plate 30 is placed above the positioning panel 11. At the same time, the positioning panel 11 is hollowed out with a preset avoidance groove 16 for the connection plate 33 to move. Since the push plate 30 is above the positioning panel 11, a protective cover 15 is provided on the positioning panel 11 above the push plate 30. The protective cover 15 is closed on three sides and opened on one side to facilitate the push plate 30 to enter and exit. The protective cover 15 is used to protect the push plate 30 in a non-working state to prevent it from being hit and damaging the positioning cylinder, guide rod and other components of the alignment assembly.

[0033] Please also read Figure 4 As shown, in order to achieve the alignment, calibration and pushing-fitting functions of the touchpad, a touchpad alignment and calibration component 100 and a pushing-fitting component 200 are provided inside the distribution box 10 and directly below the touchpad positioning cavity 14 on the positioning panel 11. The two functional components are integrated on an assembly support plate 46, and the assembly support plate 46 is fixedly mounted on the bottom plate inside the distribution box 10 by bolts.

[0034] The upper part of the assembly support plate 46 is provided with an alignment calibration component 100 and a push-fit component 200 in sequence, and the touch panel is placed flat on the push-fit component 200. The lower part of the assembly support plate 46 is fixedly connected with an alignment jacking cylinder 60 and a push-fitting cylinder 61.

[0035] The guide rod of the alignment lifting cylinder 60 passes through the assembly support plate 46 and is connected to the alignment calibration assembly 100. The alignment of the touch panel is achieved by the alignment lifting cylinder 60, and the gap between the edge of the touch panel and the touch module 21 after assembly is adjusted and controlled. The guide rod of the push lifting cylinder 61 passes through the assembly support plate 46 and is connected to the push fitting assembly 200. The push lifting cylinder 61 is operated to smoothly fit the touch panel onto the touch module 21.

[0036] The push-fit assembly 200 is composed of a placement platform 40 and a first positioning column 41 placed at the bottom of the placement platform 40. The alignment and calibration assembly 100 is mainly composed of a loading plate 42 and a linkage assembly 45. The loading plate 42 is integrated with the linkage assembly 45. A rectangular or square recessed groove 44 is designed in the middle of the loading plate 42. The placement platform 40 of the push-fit assembly 200 is in the recessed groove 44, and the placement platform 40 and the bottom plane of the recessed groove 44 do not contact each other.

[0037] The first positioning column 41 at the bottom of the placement platform 40 and the guide rod connected to the push-up cylinder 61 at the bottom of the placement platform 40 all pass through the recessed groove 44 and the holes at the corresponding positions on the assembly support plate 46. The guide rod connected to the alignment lift cylinder 60 at the bottom of the loading plate 42 passes through the holes at the corresponding positions on the assembly support plate 46. At the same time, in order to improve the stability of the loading plate 42 moving up and down, positioning holes 43 are set around the loading plate 42, and second positioning columns 47 are set at corresponding positions on the assembly support plate 46. When the loading plate 42 is assembled with the assembly support plate 46, the second positioning column 47 is inserted into the positioning hole 43, thereby improving the stability of the loading plate 42 moving up and down.

[0038] As the core component of the present invention, the main working purpose of the linkage component 45 is to realize the horizontal positioning calibration of the touch panel, so as to control the gap between the edge of the touch panel and the surrounding of the touch module after assembly, so as to meet the quality requirements of production control. Figure 5 In this embodiment, there are 8 groups of linkage components 45, and every two groups are arranged on one side of the recessed groove 44. Each group of linkage components 45 is composed of linkage guide pillars 49, L-shaped plugs 52, plug pressure plates 50, sliders 54, guide rails 55, springs 56 and spring seats 53. The guide rails 55 and spring seats 53 are installed on the loading plate 42. The L-shaped plugs 52 are assembled on the sliders 54 through the plug pressure plates 50. The sliders 54 are embedded on the guide rails 55 and connected to the spring seats 53 through the springs 56. The expansion and contraction direction of the springs 56 is consistent with the length direction of the guide rails 55. After the assembly is completed, the 8 L-shaped plugs 52 are enclosed together to form a rectangle or a square. In the initial state, the area of ​​the plug enclosed area is slightly larger than the area size of the touch panel. As the slider 54 moves on the guide rails 55, it drives the L-shaped plugs 52 to approach the edge of the touch panel until it abuts.

[0039] The movement of the slider 54 on the guide rail 55 is achieved by the cooperation between the linkage guide column 49, the plug plate 50 and the spring 56 when the loading plate 42 moves up and down. The bottom of the linkage guide column 49 is installed on the assembly support plate 46, and the middle part is cylindrical and passes through the hole at the corresponding position on the loading plate 42, and the top is a truncated cone with a small top and a large bottom. Correspondingly, the plug plate 50 has an abutting end. In the initial state, the abutting end of the plug plate 50 abuts against the bottom of the truncated cone position on the linkage guide column 49.

[0040] As the guide rod of the alignment lifting cylinder 60 drives the loading plate 42 to move upward a certain distance, the contact position of the abutting end of the plug plate 50 and the linkage guide column 49 gradually moves from the bottom of the truncated table to the top. Since the spring 56 is always in a compressed state, the spring 56 will push the slider 54 forward and drive the L-shaped plug plate 52 to close to the middle until the four sides of the touch panel are clamped, thereby realizing the horizontal positioning and calibration of the touch panel. At this time, the placement platform 40 and the bottom plane of the concave groove 44 are still not in contact with each other.

[0041] Next, the placement platform 40 is driven to move upward by a certain distance by pushing the guide rod of the lifting cylinder 61, so that the touch pad that has been positioned and calibrated on the placement platform 40 is pushed to fit on the touch module 21 of the keyboard frame 20, and maintained for several seconds until it fits tightly. It is worth noting that the touch pad is always clamped by the L-shaped plug during the upward movement process to avoid failure of horizontal positioning and calibration during the upward movement.

[0042] Then, as the guide rod of the alignment lifting cylinder 60 drives the loading plate 42 to move downward, the abutting position of the plug pressing plate 50 and the linkage guide column 49 gradually moves from the top of the truncated table to the bottom, driving the slider 54 to compress the spring 56, so that the L-shaped plug 52 returns to the initial position. At the same time, the guide rod of the lifting cylinder 61 drives the placement platform 40 to move downward, so that the placement platform 40 returns to the initial position.

[0043] Finally, the vacuum suction cup assembly 13 stops working, and at the same time, the push plate 30 of the alignment assembly returns to its initial position, and the assembled keyboard frame ( Figure 1 To complete an assembly operation.

[0044] By replacing the linkage guide pillars 49 of different sizes, changing the size of the truncated cone on the linkage guide pillars 49 and controlling the displacement of the L-shaped plug 52 , the processing requirements of touch panels of different sizes can be met.

[0045] The above contents are merely examples and explanations of the concept of the present invention. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
