Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing, and more specifically to a battery lead pressing device for pressing battery leads onto the sealing plate of a battery. Background Technology

[0002] In the battery manufacturing process, a battery lead pressing device is needed to press the battery leads onto the battery sealing plate, thus bonding the two together. Previous battery lead pressing devices used a cylinder to push a pressure block to press the battery leads onto the sealing plate. This method had the following problems: the cylinder's extension and retraction cycle was unstable, leading to inconsistent production rhythm and low production efficiency; it required high accuracy in the cylinder's stroke, down to the millimeter level. Insufficient cylinder stroke would prevent the battery leads from being firmly pressed onto the sealing plate, while excessive stroke would damage both the battery leads and the sealing plate. Therefore, the cylinder was expensive, difficult to manufacture, and prone to quality problems due to insufficient or excessive stroke; to ensure the cylinder's stroke accuracy, other parts of the battery lead pressing device also required high machining accuracy, resulting in high costs; and the battery lead pressing device required continuous fine-tuning after installation, which was difficult. Utility Model Content

This battery lead pushing device has a stable working cycle, high pushing accuracy, can avoid quality problems caused by insufficient or excessive pushing stroke during pushing, and does not require frequent fine-tuning.

[0004] The battery lead pushing device of the first embodiment of this utility model includes: a pushing block for pushing the battery lead; a buffer mechanism connected to the pushing block, which buffers the push when the pushing force applied by the pushing block exceeds a certain threshold; and a cam mechanism including a cam and a cam follower, wherein the cam rotates and drives the pushing block and the buffer mechanism to perform intermittent horizontal reciprocating motion via the cam follower.

[0005] According to the battery lead pushing device of the first embodiment of the present invention, the pushing block is driven by a cam mechanism, so the working cycle is stable and the pushing accuracy is high.

It can also avoid quality problems caused by insufficient or excessive pushing stroke during pushing.

[0006] The second embodiment of the battery lead pushing device of this utility model is as follows: In the first embodiment of the battery lead pushing device, the buffer mechanism is a cylinder, and the cam mechanism drives the cylinder and the pushing block to perform intermittent horizontal reciprocating motion.

A slider is fitted into the sliding groove of the sliding groove connecting rod. The connecting rod drives the sliding groove connecting rod to swing up and down, thereby causing the pushing block and the buffer mechanism to move horizontally reciprocally via the slider.

[0009] According to the present invention, a third-party battery lead pushing device can reliably construct a cam follower that can convert the rotational motion of the cam into the horizontal reciprocating motion of the pushing block and the buffer mechanism.

[0011] According to the fourth embodiment of the present invention, the battery lead pushing device can reliably convert the up-and-down movement of the connecting rod into the horizontal reciprocating movement of the slider.

[0012] The fifth embodiment of the battery lead pushing device of this utility model is an embodiment of the battery lead pushing device of the first and second embodiments, which further includes a mechanical limiting mechanism for limiting the maximum movement position of the pushing block.

[0013] According to the fifth embodiment of the present invention, the battery lead pushing device can reliably limit the maximum stroke of the pushing block, preventing excessive stroke of the pushing block from damaging the battery lead and the sealing plate.

[0014] The sixth embodiment of the battery lead pushing device of this utility model is as follows: In the fifth embodiment of the battery lead pushing device, the mechanical limiting mechanism consists of a fixed stop and a protrusion provided on the stop. The protrusion protrudes relative to the stop towards the pushing block and the amount of protrusion can be adjusted.

[0015] According to the sixth embodiment of the present invention, the battery lead pushing device can adjust the defined position.

[0016] The seventh embodiment of the battery lead pushing device of this utility model is an embodiment that, in the first and second embodiments of the battery lead pushing device, further includes a position sensor for detecting the position of the pushing block.

[0017] The battery lead pushing device according to the seventh embodiment of this utility model can monitor the position of the pushing block in real time.

Figure 2 This is a perspective view showing a partial structure of the battery lead pushing device of this utility model. Figure 3 This is one of the side views showing the structure of the battery lead pushing device of this utility model. Figure 4 This is the second side view showing the structure of the battery lead pushing device of this utility model.

[0027] like Figure 1 and Figure 2 As shown, the battery lead pushing device 100 includes a pushing block 1, a cam mechanism 2, and a buffer mechanism 3. The pushing block 1 can move on a horizontal plane to push the battery lead. The cam mechanism 2 includes a cam 21 and a cam follower 22. The cam 21 is mounted on a rotating shaft, which drives the cam 21 to rotate. Figure 3 and Figure 4 As shown, the cam follower 22 includes a connecting rod 221 and a sliding connecting rod 222. The connecting rod 221 reciprocates in the vertical direction under the action of the cam 21. The sliding connecting rod 222 is formed into a V-shaped bend and is configured to swing up and down around the bend point. The end of the sliding connecting rod 222 located on one side of the bend point is connected to the connecting rod 221, and a groove is formed on the other side of the bend point. The slider is fitted into the groove of the sliding connecting rod 222. The connecting rod 221 drives the sliding connecting rod 222 to swing up and down, thereby causing the slider to drive the push block 1 to move horizontally back and forth.

[0028] like Figure 2As shown, the battery lead pushing device 100 also has a buffer mechanism 3. In this 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 retracts, thereby reducing the pressure applied by the pushing block 1 to the battery lead.

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

[0030] In addition, such as Figure 2 as well as Figure 3 , Figure 4 As shown, the battery lead pushing device of this utility model also includes a mechanical limiting mechanism 4 that limits the maximum movement position of the pushing block. The mechanical limiting mechanism consists of a fixed stop and a protrusion provided on the stop. The protrusion protrudes towards one side of the pushing block relative to the stop, and the amount of protrusion can be adjusted. Because of the mechanical limiting mechanism, the maximum stroke of the pushing block 1 can be reliably limited, preventing damage to the battery lead and sealing plate caused by excessive stroke of the pushing block. In addition, since the amount of protrusion of the protrusion can be adjusted, the limited position can be finely adjusted.

[0031] In addition, such as Figure 2 As shown, the battery lead pushing device of this utility model also has a position sensor 5 for detecting the position of the pushing block and an alarm device (not shown), so that the position of the pushing block can be monitored in real time. When the position sensor detects an abnormality in the position of the pushing block, the alarm device will remind the operator to prevent quality problems.

[0032] The battery lead pushing device of this utility model has been described above. However, this utility model is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit and scope of this utility model. It will be apparent to those skilled in the art that various omissions, modifications, and variations can be made to this utility model without departing from its spirit or scope. Therefore, it should be understood that this utility model includes changes and variations within the scope of the appended claims and their equivalents. In particular, it should be understood that any combination of any part or all of any two or more of the above-described embodiments and their variations is within the scope of this utility model.
