[0030] like Figures 1-2 As shown, one embodiment of the present invention is that the energy storage battery welding device includes a laser galvanometer 1, a cylinder 2 and a clamping assembly 3. The cylinder 2 is disposed on one side of the laser galvanometer 1, and the clamping assembly 3 is disposed on the working end of the cylinder 2. The clamping assembly 3 includes a base 30 disposed on the working end of the cylinder 2.

[0031] The first slider 31 is slidably disposed in the base 30 along the first direction, and its first end is provided with a first inclined surface 36 and its second end is provided with a second inclined surface 37.

[0032] The second slider 32 is slidably disposed in the base 30 along the second direction, and its first end is provided with a third inclined surface 38, which is slidably connected to the first inclined surface 36;

[0033] The third slider 33 is parallel to the second slider 32 and is slidably disposed in the base 30. Its first end is provided with a fourth inclined surface 39, which is slidably connected to the second inclined surface 37.

[0034] The first clamping rod 34 is disposed at the second end of the second slider 32 and extends to the outside of the base 30;

[0035] The second clamping rod 35 is disposed at the second end of the third slider 33 and extends to the outside of the base 30.

[0036] In this embodiment, the laser galvanometer 1 is vertically arranged, with the first direction being horizontal and the second direction being vertical. The cylinder 2 is vertically arranged behind the laser galvanometer 1, and the clamping assembly 3 is arranged at the working end of the cylinder 2. The base 30 is vertically arranged at the working end of the cylinder 2. The first slider 31 is horizontally slidably arranged inside the upper side of the base 30, with a first inclined surface 36 at its left end and a second inclined surface 37 at its right end. The second slider 32 is vertically slidably arranged inside the left side of the base 30, with a third inclined surface 38 at its top. The third inclined surface 38 and the first inclined surface 36 are slidably connected. The third slider 33 is vertically slidably arranged inside the right side of the base 30, with a fourth inclined surface 39 at its top.

The bottom ends of the first clamping rod 34 and the second clamping rod 35 are both located outside the base 30.

[0037] When welding the electrode post and the connecting piece, the cylinder 2 drives the base 30 to move downward. If the left electrode post is higher than the right electrode post, the bottom end of the first pressing rod 34 first contacts the left end of the connecting piece. When the base 30 continues to move downward, the second sliding block 32 slides upward, the third inclined surface 38 pushes the first sliding block 31 to move rightward through the first inclined surface 36, and the second inclined surface 37 pushes the third sliding block 33 to move downward through the fourth inclined surface 39, so that the second pressing rod 35 moves downward to press the right end of the connecting piece. The laser galvanometer 1 starts to weld. If the right electrode post is higher than the left electrode post, the first sliding block 31, the second sliding block 32 and the third sliding block 33 move in the opposite direction, so that the two ends of the connecting piece are tightly attached to the two electrode posts respectively, thereby avoiding the case of false welding due to uneven connecting piece or inconsistent height of the electrode posts. The cylinder is selected to be a cylinder with buffer, and the speed is slow at the end of the stroke, so that the pressing assembly has adjustment time and space.

[0038] The application drives the base 30 to move downward through the cylinder 2, so that one pressing rod first contacts one end of the connecting piece with high height. The extension length of the other pressing rod is adjusted through the first sliding block 31, the second sliding block 32 and the third sliding block 33, so that the two pressing rods press the two ends of the connecting piece respectively, thereby facilitating the laser galvanometer welding and avoiding the case of false welding due to uneven connecting piece or inconsistent height of the electrode posts.
