Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a manual pole cap removal mechanism. Background Art

[0002] In order to improve the volumetric energy density of the battery, the current practice is to increase the utilization rate of the interior of the battery casing, that is, the bus in each single cell of the battery adopts a direct connection structure, and the bus is immersed in a glue tank for sealing, and the pole connected to the outside is directly connected to the bus. During the assembly process, the pole needs to be sealed with glue at the same time, and the middle cover on the pole is covered with a cap. After the glue dries, the cap on the pole needs to be unscrewed with a special tool.

[0003] As for the mechanism for manually removing the pole cap, it is necessary to first put it on the pole cap, and then apply an oblique force to the pole cap to remove the pole cap. However, this method has a disadvantage. Since the pole cap is subjected to an oblique force, the pole cap is easily stuck in the mechanism for putting the pole cap on. When this happens, the personnel can only use their hands to directly apply force to the stuck pole cap to remove it, which is difficult and takes a long time. Utility Model Content

[0004] The main purpose of the utility model is to provide a manual pole cap removal mechanism. When the push rod moves downward, it can be inserted into the quick release head, so as to push out the pole cap in the quick release head, thereby preventing the pole cap from being stuck in the quick release head, so as to facilitate continuous use by personnel.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Furthermore, the quick-release head includes a connecting portion threadedly connected to the second socket, a sleeve matching the pole cap is fixedly connected to the bottom of the connecting portion, a through hole matching the second socket is opened on the top surface of the connecting portion, and the bottom of the push rod passes through the through hole and extends into the sleeve.

[0008] Furthermore, the first socket is located above the second socket and the aperture of the first socket is smaller than that of the second socket, an elastic member is sleeved around the outer periphery of the push rod located in the second socket, a limiting ring is also fixed around the outer periphery of the push rod, the top surface of the limiting ring contacts the inner top of the second socket, the top of the elastic member contacts the limiting ring, and the bottom of the elastic member contacts the top of the connecting part.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-4 As shown, a manual pole cap removal mechanism includes a pipe column 1, in which a first socket 10 and a second socket 4 are arranged in communication, the first socket 10 is located above the second socket 4 and the aperture of the first socket 10 is smaller than the aperture of the second socket 4, a push rod 5 is inserted into the first socket 10, and the bottom of the push rod 5 extends into the second socket 4, a quick-release head 2 sleeved on the periphery of the pole cap is detachably fixed at the bottom of the pipe column 1, and the bottom of the push rod 5 passes through the quick-release head 2 to push out the pole cap in the quick-release head 2.

[0024] In this embodiment, if Figure 3 As shown, the quick-release head 2 includes a connecting portion 201 threadedly connected to the second socket 4, a sleeve 202 matching the pole cap is fixedly connected to the bottom of the connecting portion 201, a through hole 203 matching the second socket 4 is opened on the top surface of the connecting portion 201, the bottom of the push rod 5 passes through the through hole 203 and extends into the sleeve 202, the sleeve 202 is sleeved on the outside of the pole cap, and then force is applied to the pipe column 1. At this time, the pole cap is subjected to force, thereby separating from the pole to realize the removal of the pole cap, and the removed pole cap is usually engaged in the sleeve 202. Therefore, the personnel should manually drive the push rod 5 to slide downward, so that the push rod 5 pushes the pole cap in the sleeve 202 out.

[0025] The quick-release head can be replaced, so that by replacing the removal heads of different specifications, the device can be applied to the removal of pole caps of different poles on multiple groups of batteries.

[0026] Among them, Figure 1 As shown, the first socket 10 is located above the second socket 4 and the aperture of the first socket 10 is smaller than that of the second socket 4. An elastic member 3 is sleeved on the outer periphery of the push rod 5 located in the second socket 4. A limiting ring 11 is also fixed on the outer periphery of the push rod 5. The top surface of the limiting ring 11 contacts the inner top of the second socket 4, the top of the elastic member 3 contacts the limiting ring 11 and the bottom of the elastic member 3 contacts the top of the connecting portion 201. The elastic member 3 is a cylindrical spring. The limiting ring 11 cannot pass through the first socket 10 and is fixedly connected to the push rod 5. Therefore, when the push rod 5 descends, the limiting ring 11 will compress the elastic member 3. Therefore, when the personnel do not apply downward force to the push rod 5, the push rod 5 will be reset under the action of the elastic member 3, waiting for subsequent use by the personnel.

[0027] Among them, Figure 1 and Figure 4The figure also includes a base assembly, which includes a storage box body 6 with an open top, a positioning ring 7 is provided at the top of the storage box body 6, the outer side of the positioning ring 7 is fixedly connected to the inner wall of the storage box body 6 by at least one group of connecting rods 8, the sleeve 202 is inserted into the positioning ring 7 and the positioning ring 7 is in contact with the bottom surface of the connecting part 201, and the position where the connecting part 201 and the sleeve 202 are connected is expanded outward to form a step. After the sleeve 202 is inserted into the positioning ring 7, the step surface will contact the positioning ring 7, so that the quick-release head 2 will be aligned with the storage box body 6 and have good stability. At this time, when the push rod 5 pushes the pole cap out of the sleeve 202, the pole cap will fall into the storage box body 6, which is convenient for collection and prevents the pole cap from flying around due to the large force applied when it is pushed out of the sleeve 202.

[0028] The working principle is to align the quick-release head 2 at the bottom of the pipe column 1 with the pole cap, so that the sleeve 202 is sleeved on the periphery of the pole cap. At this time, force is applied to the pipe column 1, so that the pole cap is subjected to force and detached from the pole to realize the removal of the pole cap. When the removed pole cap is engaged in the sleeve 202, the personnel should manually drive the push rod 5 to slide downward, so that the push rod 5 pushes the pole cap in the sleeve 202 out. During this process, the limit ring 11 will press down the elastic member 3. Therefore, when the personnel stop applying force to the push rod 5, the push rod 5 will be reset under the action of the elastic member 3, waiting for the personnel to use this mechanism later. Moreover, when the pole cap is pushed out of the sleeve 202, the sleeve 202 can be inserted into the positioning ring 7. Therefore, when the push rod 5 pushes the pole cap out of the sleeve 202, the pole cap will fall into the storage box 6, which is convenient for collection.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
