[0042] like Figure 1 As shown, the grasping mechanism includes a transfer module, a first clamp 32 and a limit switch 33. The battery assembly 1 equipped with the power-collecting device 2 can be transported to the grasping mechanism. The transfer module is arranged on the side of the battery assembly 1 equipped with the power-collecting device 2. The first clamp 32 and the limit switch 33 are both arranged at the driving end of the transfer module, so that the first clamp 32 and the limit switch 33 can move under the drive of the transfer module, and the power-collecting device 2 on the battery assembly 1 is located within the moving range of the first clamp 32 and the limit switch 33, that is, the limit switch 33 can be moved to a position in contact with the power-collecting device 2 under the drive of the transfer module, so that the limit switch 33 can position the power-collecting device 2, and the first clamp 32 can be moved to a position where the power-collecting device 2 can be grasped under the drive of the transfer module, so that the first clamp 32 can grasp the power-collecting device 2 and drive the power-collecting device 2 to move, so as to separate the power-collecting device 2 and the battery assembly 1.
[0043] In the actual process of separating the battery assembly 1 and the power-collecting fixture 2, the position of the limit switch 33 is first adjusted by using the transfer module until the limit switch 33 contacts the power-collecting fixture 2, so as to detect the power-collecting fixture 2 through the limit switch 33; then, according to the acquired position information of the power-collecting fixture 2, the position of the first clamp 32 is adjusted by using the transfer module, so that the first clamp 32 is opposite to the power-collecting fixture 2, so that the power-collecting fixture 2 can be grasped by the first clamp 32 and driven away from the battery assembly 1, thereby completing the separation of the power-collecting fixture 2 from the battery assembly 1.
[0044] The gripping mechanism of the present application directly sets a limit switch 33 on the transfer module to use the limit switch 33 to locate the position of the power-taking tool 2 on the battery assembly 1. It can not only achieve accurate positioning of the power-taking tool 2, so that the first clamp 32 can accurately grip the power-taking tool 2, but also has a simple structure, greatly reducing the equipment cost.
[0045] In one embodiment of the present application, preferably, Figure 1 As shown, the power-collecting tool 2 is located on one side of the first direction a of the battery assembly 1, and the battery assembly 1 can be placed horizontally on the grasping mechanism to separate the power-collecting tool 2.

The first drive device 3 is connected to the drive end of the second drive device 4, so that the first drive device 3 can move along the second direction b under the drive of the second drive device 4. The second direction b is perpendicular to the first direction a, that is, the first direction a is along the horizontal direction, and the second direction b is perpendicular to the length direction of the power extraction tooling 2.

[0048] After the position of the power-collecting fixture 2 is determined by the limit switch 33, the first driving device 3 and the second driving device 4 are used to adjust the position of the first clamp 32 on the support beam 31 along the first direction a and the second direction b, so as to grasp the power-collecting fixture 2 through the first clamp 32 and drive the power-collecting fixture 2 away from the battery assembly 1, so as to achieve the separation of the battery assembly 1 and the power-collecting fixture 2.

In the initial position, the rocker hangs vertically, and the ball at the lower end of the rocker is lower than the first clamp 32, so that the first clamp 32 does not affect the contact between the ball and the power extraction fixture 2; when the first clamp 32 needs to move down to grab the power extraction fixture 2, the ball can contact the battery assembly 1 and swing upward under the push of the battery assembly 1, so as not to affect the downward movement of the first clamp 32.
[0051] In one embodiment of the present application, preferably, the number of the limit switches 33 is multiple, and the multiple limit switches 33 are arranged at intervals along the length direction of the support beam 31.
