The lifting plate 9 is located at... A second bearing 10 is fixedly connected to the upper end face of one end of the telescopic cylinder 8. The inner side wall of the inner ring of the second bearing 10 is fixedly connected to the bottom end of the spline shaft 7. A top plate 11 is fixedly connected to the top end of the spline shaft 7. A clamping structure 12 is provided on the lower side of the top plate 11. A battery clip 13 is installed on the upper end face of the positioning table 1. Placing the main board in the main board placement slot 2 can ensure the stability of the main board during the welding process. The lifting plate 9 is driven to move up and down by the telescopic cylinder 8, thereby adjusting the second bearing 10, the spline shaft 7 and the top plate 11 to lift and lower, so as to facilitate the clamping and release of the battery, and thus facilitate the positioning and installation of the battery.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the smoke blowing structure 3 further includes a mounting frame 301 fixed to the left end of the upper surface of the positioning table 1. Two vortex fans 302 are symmetrically and fixedly connected inside the mounting frame 301. Filter screens 303 are fixedly connected to both the left and right ends of the mounting frame 301. The vortex fans 302 can blow air to remove the smoke, preventing the smoke from affecting the eyes of the welding personnel, and can also cool the motherboard.

[0030] like Figure 2 and Figure 3 As shown in the preferred embodiment, based on the above method, the rotating structure 6 further includes a driven gear 601 fixed on the rotating tube 5, a support frame 602 fixedly connected to the lower end face of the positioning table 1, a first servo motor 603 fixedly connected to the support frame 602, and a drive gear 604 meshing with the driven gear 601 through the drive end of the first servo motor 603. The first servo motor 603 can drive the drive gear 604 to rotate, the rotation of the drive gear 604 drives the driven gear 601 and the rotating tube 5 to rotate, the rotation of the rotating tube 5 drives the spline shaft 7 to rotate, thereby rotating the top plate 11, and thus positioning and installing the clamped battery.

[0031] like Figure 1 , Figure 2 and Figure 4As shown, in a preferred embodiment, based on the above method, the clamping structure 12 further includes an assembly frame 1201 fixed to the right end of the lower end face of the top plate 11. A connecting plate 1202 is fixedly connected to the bottom end of the assembly frame 1201. A threaded rod 1203 is rotatably connected between the assembly frame 1201 and the connecting plate 1202. A second servo motor 1204 is fixedly connected inside the assembly frame 1201. The drive end of the second servo motor 1204 is fixedly connected to the top end of the threaded rod 1203. Two symmetrical movable openings 1205 are opened on the connecting plate 1202. A slider 1206 is slidably connected to each of the two movable openings 1205.

Two connecting rods 1209 are symmetrically and rotatably connected to the movable block 1208. The bottom ends of the two connecting rods 1209 are rotatably connected to the sliders 1206 respectively. Rubber pads 1210 are fixedly connected to the inner sidewalls of the clamping plates 1207. The threaded rod 1203 is driven to rotate by the second servo motor 1204. The rotation of the threaded rod 1203 causes the movable block 1208 to move. The movement of the movable block 1208 drives the connecting rods 1209 to move, so that the two sliders 1206 move inward or outward at the same time. This realizes the opposite or opposite movement of the clamping plates 1207, thereby accurately clamping the battery and ensuring stability during the transfer process. The rubber pads 1210 can protect the battery.

[0032] like Figure 1 As shown, in a preferred embodiment, based on the above method, the lower end face of the positioning stage 1 is further fixedly connected to the frame 14; the frame 14 can support the positioning stage 1.

[0034] Specifically, when using this battery and motherboard PCB welding positioning device: the motherboard is placed in the motherboard placement slot 2, and then the battery is placed in the battery holder 13. The telescopic cylinder 8 is driven to lower the lifting plate 9, thereby driving the second bearing 10, spline shaft 7, and top plate 11 to descend, so that the clamping plate 1207 descends to the target height. Then, the second servo motor 1204 drives the threaded rod 1203 to rotate. The rotation of the threaded rod 1203 causes the moving block 1208 to move. The movement of the moving block 1208 drives the connecting rod 1209 to move, thereby causing the two sliders 1206 to move. Simultaneously, the clamping plate 1207 moves inward to precisely clamp the battery. Then, the telescopic cylinder 8 drives the clamped battery to rise to the target height. Then, the first servo motor 603 drives the drive gear 604 to rotate. The rotation of the drive gear 604 drives the driven gear 601 and the rotating tube 5 to rotate. The rotation of the rotating tube 5 drives the spline shaft 7 to rotate, thereby rotating the battery 180 degrees to be directly above the motherboard welding position. Then, the telescopic cylinder 8 drives the battery to descend into the welding position for welding. The vortex fan 302 blows air to blow away the smoke generated during welding.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
