The rotating device 400 can be arranged on the support frame 200 and directly drive the gripping device 300 to rotate, or the rotating device 400 can be arranged on the gripping device 300 and drive the connection support frame 200. The reaction force during driving enables the gripping device 300 to rotate relative to the support frame 200, thereby adjusting the angle of the gripping device 300. On the one hand, when the gripping device 300 grasps the battery module, the gripping device 300 can be aligned with the battery module, reducing the angular deviation between the gripping device 300 and the battery module, thereby improving the accuracy of grasping the battery module and the stability after grasping; on the other hand, the transfer equipment is used in the process of assembling the battery module into the battery casing. When the gripper device 300 places the battery module into the battery housing, adjusting the angle of the gripper device 300 can align the gripped battery module with the battery housing, reduce the angular deviation between the battery module and the battery housing, thereby improving the accuracy of battery module assembly and reducing the possibility of collision between the battery module and the battery housing; on the other hand, specifically in this embodiment, two battery modules in opposite directions need to be loaded into a battery housing. After the gripper device 300 grabs the battery modules in the same direction on the conveyor line, the gripper device 300 is rotated by the rotating device 400, so that it is easy to make the front and rear battery modules grabbed in opposite directions and then load them into the battery housing.

The limit assembly 420 includes a detection member 421 and a photoelectric switch 422. When the detection member 421 triggers the photoelectric switch 422, the rotary drive assembly 410 stops driving the gripper device 300 to rotate. The detection member 421 can be set on the gripper device 300, and the photoelectric switch 422 can be set on the support frame 200, so that the detection member 421 rotates with the gripper device 300; the photoelectric switch 422 can also be set on the gripper device 300, and the detection member 421 can be set on the support frame 200, so that the photoelectric switch 422 rotates with the gripper device 300.

The first linear drive mechanism 140 includes a second rack 141, a second gear 142, a second motor 143 and a transmission assembly. The second rack 141 is fixed on the truss assembly 110, and the second motor 143 is arranged on the first slide 120. The second motor 143 drives and connects to the transmission assembly, and the transmission assembly transmits and connects to the second gear 142. The second gear 142 meshes with the second rack 141 and moves along the second rack 141, so that the first slide 120 moves linearly relative to the truss assembly 110. Specifically in this embodiment, a rotatable auxiliary gear is provided on one side of the second gear 142, and the auxiliary gear also meshes with the second rack 141. The auxiliary gear provides a certain guiding effect, improves the stability of the meshing of the second gear 142 and the second rack 141, and reduces the possibility of the second gear 142 and the second rack 141 being separated.

[0104] In one embodiment, the transmission assembly comprises:

[0105] A first reducer 144 is disposed on the first carriage 120 , and the second motor 143 is driven and connected to the first reducer 144 ;

[0106] A second speed reducer 146 is disposed on the first carriage 120 and drivingly connected to the second gear 142; and

[0107] The transmission shaft 145 is transmission-connected to the first reducer 144 and the second reducer 146 .

[0108] Reference Fig. 9In the embodiment of the utility model, the transmission assembly includes a first reducer 144, a second reducer 146 and a transmission shaft 145. The first reducer 144 and the second reducer 146 play the role of adjusting the rotation speed and changing the transmission direction, so that the structure of the entire first linear drive mechanism 140 is more compact and occupies less space. Specifically in this embodiment, two slide rails are arranged between the first slide 120 and the truss assembly 110, and a second rack 141 is fixed on each slide rail. A transmission shaft 145 is arranged on both sides of the first reducer 144, and each transmission shaft 145 is correspondingly provided with a second reducer 146. Each second reducer 146 is correspondingly provided with a second gear 142. The two second gears 142 are respectively meshed with the two second racks 141, which improves the stability of the first slide 120 moving along the X direction on the truss assembly 110. The second motor 143 arranged in the middle drives the two gear rack mechanisms on both sides to move, thereby improving the synchronization of movement, simplifying the structure, and reducing the manufacturing cost.

[0109] In one embodiment, the second linear drive mechanism 150 includes a third motor 151, a screw rod 152 and a nut structure 153. One of the third motor 151 and the nut structure 153 is disposed on the first slide 120, and the other of the third motor 151 and the nut structure 153 is disposed on the second slide 130. The third motor 151 drives the connecting screw rod 152, and the screw rod 152 is passed through the nut structure 153 and is threadedly connected to the nut structure 153.

[0110] Reference Figure 11 to Figure 12 In an embodiment of the utility model, the second linear drive mechanism 150 includes a third motor 151, a screw rod 152 and a nut structure 153. The third motor 151 can be arranged on the first slide 120, and the nut structure 153 can be arranged on the second slide 130. Alternatively, the nut structure 153 can be arranged on the first slide 120, and the third motor 151 can be arranged on the second slide 130. The screw rod 152 is rotated by the third motor 151, so that the nut structure 153 on the screw rod 152 moves along the thread, thereby realizing the relative sliding of the first slide 120 and the second slide 130. The second linear drive mechanism 150 uses a lead screw and nut mechanism to achieve linear drive, and has high positioning accuracy, which is beneficial to improving the positioning accuracy of the second slide 130 in the Y direction, thereby improving the positioning accuracy of the battery module in the Y direction, ensuring the accuracy of picking and placing the battery module, and reducing the possibility of collision between the battery module and the battery module during transportation; on the other hand, the distance moved by the battery module in the Y direction is generally short, and the use of a lead screw and nut mechanism is beneficial to reducing the space occupied by the second linear drive mechanism 150, thereby making the structure of the entire transfer device 100 more compact, thereby making the transfer device 100 easy to arrange and reducing the possibility of collision between the transfer device 100 and other components.
