[0033] With the above arrangement, the first lead 210 and the second lead 220 are welded on the same side of the battery body 100 of the button battery. Therefore, in the process of welding the leads to the button battery, all the leads can be clamped on the same side of the battery body 100, and then all the leads can be welded simultaneously on the same side of the battery body 100 without flipping the battery body 100 of the button battery.

In addition, in the welding process, the battery bodies 100 of more than two button batteries can be clamped on the battery lead welding device with the cover plate 120 facing upward, thereby enabling more than two button batteries and multiple leads to be welded simultaneously, with high welding efficiency.

[0034] In the button battery provided by the utility model, the first welding plate 211 is also attached to the insulating pad 150.

With the above arrangement, the connection block 610a can be adjusted forward and backward, and the mounting block 610c can be adjusted left and right. In addition, the mounting block 610c can also be adjusted in the forward and backward direction.

[0050] It should be noted that the above-mentioned first position adjustment structure can also be set up in other ways. For example, the first position adjustment structure can include front and rear adjustment cylinders, which are connected to the connecting block 610a. The second position adjustment structure can include left and right adjustment cylinders, which are connected to the mounting block 610c, and the left and right adjustment cylinders are installed on the connecting block 610a.

[0051] It is conceivable that in other embodiments, the welding mechanism may also adopt other settings.

The first wire hole 422 and the second wire hole 424 are arranged at one end of the positioning plate 420 close to the clamping groove 411. Thus, by rotating the flip frame 430, the positioning plate 420 can be switched between the first position and the second position, which is convenient for operation. After the lead welding of the button battery is completed, it is only necessary to rotate the flip frame 430 to rotate the positioning plate 420 from the second position to the first position, so that the first welding plate 211 and the second welding plate 221 can be separated from the positioning plate 420, and at the same time, the first lead 210 can pass through the corresponding first wire hole 422, and the second lead 220 can pass through the corresponding second wire hole 424, and the unloading is completed.
