According to the structure described above, the first clamping mechanism 32 and the lifting mechanism 33 are integrated on the first support member 31, with higher integration degree and space saving, and the first clamping mechanism 32 is formed with an installation cavity, which plays a role in avoiding the lifting mechanism 33.

[0063] Further, preferably, the first support member 31 includes a box body and a first support flat plate connected to the box body; a first opening is formed at the top of the box body, and the first support flat plate is located above this first opening.

[0065] According to the structure described above, the first driving device 323 can drive the first clamping member 321 to move towards the second clamping member 322, so as to clamp the battery module group, and the second clamping member 322 can be used as a reference to improve the positioning accuracy.

[0066] In this embodiment, preferably, as Figure 4 and Figure 5As shown, the first clamping mechanism 32 also includes a first transmission assembly 34. Along the lifting direction of the battery module, the first driving device 323 is arranged on one side of the first supporting member 31, and the first clamping member 321 is arranged on the other side of the first supporting member 31. The driving end of the first driving device 323 is connected to the first clamping member 321 through the first transmission assembly 34. The first transmission assembly 34 plays a role of transmission, and then the first driving device 323 can be arranged below the first supporting plate, and the first clamping member 321 is connected and arranged above the first supporting plate. That is to say, along the direction perpendicular to the direction of clamping the battery module, that is, along the vertical direction, the second driving device 224 is arranged on one side of the first supporting plate, and the third clamping member 222 is arranged on the other side of the first supporting plate, so as to reasonably arrange the space. Of course, it is not limited to this, and the first transmission assembly 34 may not be arranged, and it is selected according to actual needs.

It should be noted that since both the first clamping mechanism 32 and the second clamping mechanism 22 described below are used to clamp the battery module, it is only necessary to be provided with a third pressure sensor 25 on the second clamping mechanism 22 described below. When the strokes of the two clamps are the same, the clamping forces are the same. Therefore, the first clamping mechanism 32 does not need to be provided with a pressure sensor. Of course, not limited to this, a pressure sensor can also be provided for the first clamping mechanism 32, and the structure of the first clamping member 321 can also be designed according to the third clamping member 222, including the design position of the pressure sensor, which can refer to the second clamping mechanism 22.

According to the structure described above, the lifting drive device 331 drives the bearing member 332 to push the battery module to rise along the vertical direction until the battery module enters the upper case and is installed in place, that is, the operation of loading the battery module into the case is completed.

[0072] Further, preferably, the lifting drive device 331 is an electric push cylinder. Of course, it is not limited thereto, and it can also be a linear motor, etc.; further, preferably, the bearing member 332 includes a rectangular flat plate 3322 and two T-shaped support platforms 3323 connected to the rectangular flat plate 3322.

According to the structure described above, the positioning drive device 372 drives the positioning member 373 to move and abut against the side of the battery module, shapes and positions its side, improves the assembly accuracy, and enables more accurate casing.

[0074] Further, preferably, the positioning mechanism 37 is arranged on one side of the battery module along its width direction; further, preferably, the number of the positioning mechanisms 37 is multiple, and they are all arranged on the same side of the first clamping mechanism 32, and when the battery module is clamped on the first clamping mechanism 32, the multiple positioning mechanisms 37 are sequentially arranged at intervals along the length direction of the battery module.

[0075] In this embodiment, preferably, as Figures 6 to 11 shown, the clamping device 2 includes a general support member 21 and a second clamping mechanism 22 and a third clamping mechanism 23 arranged on the general support member 21; wherein, the second clamping mechanism 22 is used to clamp the battery module, and the third clamping mechanism 23 is used to clamp the casing.

[0076] According to the structure described above, in this application, the second clamping mechanism 22 and the third clamping mechanism 23 are integrated. Then, only by rotating the direction of the robot 1, different clamping mechanisms can be used to clamp different objects.

And preferably, in the initial state, the second support member 221 is arranged along the horizontal direction, and the total support member 21 is arranged along the vertical direction; further, preferably, a connecting seat 26 is fixed on the upper surface of the second support member 221, and this connecting seat 26 is connected to the mounting seat of the robot 1.

[0118] The lateral translation mechanism 48 drives the lifting mechanism together with the clamping and flipping mechanism 46 and the longitudinal lateral translation mechanism 48 to synchronously move horizontally along the horizontal X direction to the working position. Then the longitudinal translation driving device 44 drives the two clamping and flipping mechanisms 46 to move away from each other and open through the longitudinal translation transmission assembly 45. After that, the lifting driving device 42 drives the two clamping and flipping mechanisms 46 together with the aforementioned longitudinal translation driving device 44 and the longitudinal translation transmission assembly 45 to descend to both sides of the general assembly, and makes the longitudinal translation driving device 44 drive the two clamping and flipping mechanisms 46 to move to a position where they can clamp the general assembly.

Then the clamping and flipping mechanism 46 drives the general assembly to flip until the opening of its casing is upward. Then, using the lateral translation mechanism 48, the general assembly is driven to move horizontally above the working position.
