[0026] Figure 1 It is a perspective view showing the structure of the battery lead pressing device of the present invention. Figure 2 It is a perspective view showing a partial structure of the battery lead pressing device of the present invention. Figure 3 This is one of the side views showing the structure of the battery lead pressing device of the present invention. Figure 4 This is a second side view showing the structure of the battery lead pressing device of the present invention.

[0027] like Figure 1 and Figure 2 As shown, the battery lead pressing device 100 comprises a pressing block 1, a cam mechanism 2 and a buffer mechanism 3. The pressing block 1 can move on a horizontal plane to press the battery lead. The cam mechanism 2 comprises a cam 21 and a cam follower 22. The cam 21 is arranged on a rotating shaft, and the rotating shaft can drive the cam 21 to rotate. Figure 3 and Figure 4 As shown, the cam follower 22 includes a connecting rod 221 and a sliding groove connecting rod 222. The connecting rod 221 reciprocates in the up and down directions under the action of the cam 21. The sliding groove connecting rod 222 is formed into a V-shaped bending shape, and is configured to be able to swing up and down with the bending point as the center. The end of the sliding groove connecting rod 222 located on one side of the bending point is connected to the connecting rod 221, and the sliding groove is formed on the other side of the bending point. The slider is embedded in the sliding groove of the sliding groove connecting rod 222, and the connecting rod 221 drives the sliding groove connecting rod 222 to swing up and down, thereby causing the slider to drive the push block 1 to reciprocate horizontally.

[0028] like Figure 2As shown, the battery lead pushing device 100 also has a buffer mechanism 3. In the present embodiment, a cylinder is used as the buffer mechanism 3. The buffer mechanism 3 is connected to the pushing block 1. When the pushing force applied by the pushing block 1 exceeds a certain threshold, the buffer mechanism 3 plays a buffering role, that is, the piston rod of the cylinder contracts, thereby reducing the pressure applied by the pushing block 1 on the battery lead.

[0029] According to the battery lead pressing device as described above, the cam 21 rotates and drives the pressing block 1 and the buffer mechanism 3 to perform intermittent horizontal reciprocating motion via the cam follower 22. Since the pressing block is driven by the cam mechanism, the battery lead pressing device has a stable working cycle and high pressing accuracy. In addition, since the buffer mechanism is provided, a larger tolerance can be allowed for the pressing stroke of the pressing block, which can avoid quality problems caused by insufficient or excessive pressing stroke during pushing, and the pushing block can be easily fine-tuned through the buffer mechanism.

[0030] In addition, if Figure 2 as well as Figure 3 , Figure 4 As shown, the battery lead pressing device of the present invention is also provided with a mechanical limit mechanism 4 for limiting the maximum moving position of the pressing block, and the mechanical limit mechanism is composed of a fixed stopper and a protrusion provided on the stopper, and the protrusion protrudes toward one side of the pressing block relative to the stopper and the protrusion amount can be adjusted. Due to the mechanical limit mechanism, the maximum stroke of the pressing block 1 can be reliably limited to prevent the battery lead and the sealing plate from being damaged due to excessive stroke of the pressing block. In addition, since the protrusion amount of the protrusion can be adjusted, the limited position can be fine-tuned.

[0031] In addition, if Figure 2 As shown, the battery lead pushing device of the present invention is also equipped with a position sensor 5 for detecting the position of the pushing block and an alarm device not shown in the figure, so that the position of the pushing block can be monitored in real time. When the position sensor detects that the position of the pushing block is abnormal, the alarm device sends a reminder to the operator to prevent quality problems.

[0032] The battery lead pressing device of the present invention has been described above, but the present invention is not limited to the above-mentioned embodiments, and various changes can be made within the scope of the main purpose of the present invention. For those skilled in the art, it is obvious that various omissions, changes and deformations can be made to the present invention without departing from the spirit or scope of the present invention. Therefore, it should be understood that the present invention includes changes and deformations within the scope of the attached claims and their equivalents. In particular, it should be understood that when any part or all of any two or more of the above-mentioned embodiments and their deformations are combined, it can be understood that it is within the scope of the present invention.
