Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1

[0030] As Figure 1As shown in the figure, this embodiment provides a module integrated cover plate assembly device, which includes an ear straightening mechanism 1, a module conveying mechanism 2, and an integrated cover plate handling mechanism (not shown in the figure).

[0031] As Figure 1 , Figure 2 shown, the ear straightening mechanism 1 is placed mirror-symmetrically before and after the module conveying mechanism 2. The ear straightening mechanism 1 can synchronously straighten and level multiple ears 41 of the module 4 on the module conveying mechanism 2. The integrated cover plate handling mechanism can place multiple holes on the integrated cover plate corresponding to the multiple ears 41 to complete the assembly of the module 4 and the integrated cover plate.

[0032] As Figure 1 , Figure 2 , Figure 3 shown, the ear straightening mechanism 1 includes a support base 11, a three-axis assembly 12, a mounting base 13, and an ear straightening assembly 14. The support base 11 is fixed with a three-axis assembly 12. The three-axis assembly 12 is fixed with a mounting base 13. The mounting base 13 is fixed with multiple ear straightening assemblies 14. The three-axis assembly 12 can drive the ear straightening assemblies 14 to move in three directions of X, Y, and Z. The three-axis assembly 12 includes a Y-axis lead screw module 121, an X-axis lead screw module 122, and a Z-axis lead screw module 123. One Y-axis lead screw module 121 is fixed on each side of the support base 11. The X-axis lead screw module 122 is slidably connected between the Y-axis lead screw modules 121. The Z-axis lead screw module 123 is slidably connected to the X-axis lead screw module 122. The free side of the Z-axis lead screw module 123 is slidably connected to the mounting base 13. The vertical section of the mounting base 13 is L-shaped. The vertical plate of the mounting base 13 is slidably connected to the Z-axis lead screw module 123. Multiple ear straightening assemblies 14 are fixed at intervals along the X-axis on the top wall of the horizontal plate of the mounting base 13. The Y-axis lead screw module 121, the X-axis lead screw module 122, and the Z-axis lead screw module 123 are all prior arts. The ear straightening assembly 14 includes a finger cylinder 141 and a comb tooth claw 142. The finger cylinder 141 is fixed on the top wall of the horizontal plate of the mounting base 13. The output end of the finger cylinder 141 is fixed with a comb tooth claw 142. The finger cylinder 141 can drive the comb tooth claw 142 to open and close. A size and pressure sensor (not shown in the figure) is fixed on the finger cylinder 141. By monitoring the pressure and opening and closing angle of the finger cylinder 141, the monitoring of pressure and size is completed.

[0033] As Figure 1 , Figure 2As shown, the module conveying mechanism 2 includes a logistics conveyor line 21, a stopping component 22, and a tray 23. A stopping component 22 is fixed on the logistics conveyor line 21 near the ear straightening mechanism 1. In this embodiment, the stopping component 22 is a cylinder. A tray 23 is placed on the logistics conveyor line 21, and a module 4 is placed on the tray 23. When the module 4 reaches the specified position, the output end of the cylinder extends to stop the tray 23. After the module 4 is assembled with the integrated cover plate, the output end of the cylinder retracts to release the tray 23.

[0034] As Figure 2 shown, the integrated cover plate handling mechanism includes a manipulator (not shown in the figure) and a vision positioning system (not shown in the figure). A vision positioning system is installed on the manipulator (which is a prior art). The vision positioning system can position the position of the ear 41.

[0035] During use, first, the logistics conveyor line 21 conveys the tray 23 with the module 4 to the stopping component 22. The stopping component 22 is a cylinder. When the tray 23 is conveyed in place, the output end of the cylinder extends to stop the tray 23, completing the logistics conveyance. Then, the finger cylinder 141 opens the comb tooth claw 142 to the required opening. Driven by the three-axis component 12, the comb tooth claw 142 accurately reaches any one of the ears 41 of the module 4. Driven by the finger cylinder 141, the comb tooth claw 142 closes by a certain distance to clamp the root of the ear 41, and then is driven by the three-axis component 12 to move along the Y-axis to complete the straightening and shaping of the ear 41. Finally, the comb tooth claw 142 moves upward along the Z-axis direction driven by the three-axis component 12. When the three-axis component 12 reaches a certain position, the manipulator grabs the integrated cover plate, and the holes on it penetrate into the corresponding ears 41. At the same time, the three-axis component 12 drives the comb tooth claw 142 to slowly move downward along the Z-axis to maintain a certain safe distance from the bottom of the integrated cover plate. When the ears 41 completely penetrate into the holes of the integrated cover plate, the three-axis component 12 moves along the Y-axis direction and leaves the module 4, that is, the assembly of the integrated cover plate and the module is completed.
