The tooth plate 122 is installed inside the guide rod 121, and the guide gear 123 is arranged on the outer side of the tooth plate 122. The positioning side plate 124 is fixedly installed on the rotating shaft connected by the key in the middle of the guide gear 123. The outer wall of the tooth plate 122 and the inner wall of the guide rod 121 fit each other, and tooth blocks are arranged on both sides of the tooth plate 122. One side of the tooth plate 122 is meshed with the guide gear 123 in the initial state. The adjusting component 13 includes a driving motor 131 and an adjusting screw 132, and the driving motor 131 is fixed inside the guide rod 121. The output end of the driving motor 131 is equipped with an adjusting screw 132, and the adjusting screw 132 is installed through the end of the tooth plate 122. The adjusting screw 132 and the tooth plate 122 are threadedly connected, and the tooth plate 122 can slide inside the guide rod 121. The negative pressure adsorption component 14 includes a linkage gear 141, a center screw 142, a piston block 143, a receiving block 144 and a gas delivery hose 145, and the linkage gear 141 is located on the side of the guide rod 121, and the center screw 142 is fixedly installed in the middle of the linkage gear 141.The lower end of the central screw 142 is connected with a piston block 143, which is installed inside the receiving block 144, and the receiving block 144 is connected to the support block 2 through the gas hose 145. The central screw 142 and the piston block 143 are threadedly connected, and the lower cross-section of the piston block 143 is set to be rectangular. The lower edge of the piston block 143 is wrapped with a sealing ring. The piston block 143 and the receiving block 144 are slidably connected. The interior of the receiving block 144 is connected to the interior of the support block 2 through the gas hose 145, and the interior of the support block 2 is set to be a hollow structure.

[0041] When it is necessary to limit the battery module with a smaller width, the battery module is placed on the support block 2, and then the servo motor 4 and the cylinder 10 are turned on. After the servo motor 4 is turned on, the transmission screw 5 can be rotated. After the transmission screw 5 is rotated, the threaded movable seat 6 can drive the first limit plate 9 to move toward the center of the bottom plate 1. After the cylinder 10 is turned on, the second limit plate 11 can also move synchronously toward the center of the bottom plate 1. Through the movement of the first limit plate 9 and the second limit plate 11, the guide rod 121 on them can contact the battery module. At this time, the guide rod 121 is forced to move in the direction away from the battery module, guiding After the rod 121 moves, it can drive the toothed plate 122 inside it to move synchronously, and the toothed plate 122 and the guide gear 123 are meshed with each other. After the toothed plate 122 moves, the guide gear 123 can be rotated, and the rotation of the guide gear 123 can drive the positioning side plate 124 to rotate synchronously. The two guide rods 121 can be used to clamp the battery module in the horizontal direction, and the rotation of the positioning side plate 124 can clamp the battery module in the width direction, thereby ensuring the stability of the battery module during the transfer process. When it is necessary to limit the width of a battery module, the drive motor 131 is turned on, and the drive motor 131 is turned on. After the first limit plate 9 and the second limit plate 11 are moved, one side of the toothed plate 122 is disengaged from the guide gear 123, while the other side is meshed with the linkage gear 141. After the first limit plate 9 and the second limit plate 11 are moved, the guide rod 121 thereon is used to clamp the battery module laterally. After the guide rod 121 moves, the inner toothed plate 122 drives the meshing linkage gear 141 to rotate. After the linkage gear 141 rotates, the center screw 142 in the middle is driven by the guide rod 121. 2 rotates synchronously, and the central screw 142 rotates to enable the piston block 143 with the threaded connection at the lower end to move upward to the receiving block 144. After the piston block 143 moves in the receiving block 144, the receiving block 144 can extract the air flow inside the support block 2 through the air delivery hose 145. At this time, negative pressure is formed inside the support block 2, so that the bottom of the battery module with a larger width can be adsorbed and fixed through the through hole 3 on the support block 2. By switching the two clamping modes of bottom adsorption and side clamping, the battery modules of different widths can be replaced to avoid the formation of a larger width direction and affecting the normal operation of other stations.
