[0024] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below in conjunction with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0026] Reference will now be made to the following Figures 1 to 3 to describe a stacked grid battery welding press according to some embodiments of the present application.

[0027] As shown in Figures 1 to 3 , the embodiments of the present application provide a stacked grid battery welding press, which comprises a press body 1 and a magnetic suction assembly.

[0028] Specifically, the magnetic suction assembly is arranged at both ends of the press body 1.

[0029] The device is suitable for a drum with a polygonal shape. Taking a dodecagonal drum as an example, since the dodecagonal drum has twelve sides with the same shape, one pressing body 1 is installed on each side, and the shape and size of the pressing body 1 are adapted to the shape and size of the side of the drum. During installation of the pressing body 1, the pressing body 1 is placed on the upper surface of the carrying table 7, and then the battery piece is placed on the upper surface of the pressing body 1. Then, the carrying table 7 is pushed to the lower side of the dodecagonal drum, and the dodecagonal drum is rotated so that one of the sides is aligned with the battery piece. Since the two ends of the pressing body 1 are provided with magnetic attraction assemblies, the magnetic attraction assemblies can be adsorbed on the side of the drum. During adsorption of the magnetic attraction assemblies on the side of the drum, the battery piece can be subjected to pressure, so that the battery piece can not fall off during welding. In addition, the shape of the pressing body 1 is flat and does not bend, so that when the battery piece contacts the side of the drum, two flat surfaces are in contact, so that the welding position can be better located, and deviation of the welding position can be avoided.

[0030] As shown in Figures 1 to 3 , in an embodiment of the present application, the pressing body 1 comprises a base 101 and an adsorption platform 102, and the adsorption platform 102 is arranged at the middle of one side of the base 101.

[0031] By arranging the adsorption platform 102 at the middle of one side of the base 101, the installation position of the battery piece can be easily located. In addition, the adsorption platform 102 has a shape of an upwardly convex arc surface. Since the surface of the battery piece is not completely flat, in order to ensure that the battery piece can be in close contact with the conductive wire, the adsorption platform 102 is arranged as an arc surface. The thickness of the adsorption platform 102 is 2-3 mm, and the radius of the arc surface is 400-600 mm. Therefore, the top of the arc surface corresponds to the position of the concave part on the side of the battery piece close to the conductive wire, so that the adsorption platform can generate a force on the protruding part of the battery piece, so that the concave part is in contact with the conductive wire as much as possible, and the welding effect is further improved. The adsorption platform 102 and the base 101 are integrally formed, so that the processing difficulty of the pressing body 1 can be reduced, and the structural strength of the pressing body 1 can be increased. The pressing body 1 is made of high-strength alloy material (such as aviation aluminum, titanium alloy, etc.). Aviation aluminum is preferred in terms of cost.

[0032] As shown in Figures 1 to 3 , in an embodiment of the present application, the magnetic attraction assembly comprises a mounting hole 2 arranged at the two ends of the base 101, and an adsorption member 3 arranged in the mounting hole 2.

[0036] As shown in the drawings, Figures 1 to 3 In one embodiment of the present application, the adsorption platform 102 is provided with grooves 6 at intervals.

[0037] The grooves 6 are arranged on the side of the adsorption platform 102 away from the base 101, the distance between the adjacent two grooves 6 is 2-4mm, so as to reduce the contact area of the battery piece and the adsorption platform 102, and further reduce the heat loss.
