Technical Field

The present invention relates to the technical field of lithium battery processing, in particular to multi-station processing equipment for a single lithium battery.

Background Art

Lithium batteries are batteries that use lithium metal or lithium alloy as anode materials and non-aqueous electrolyte solutions. When processing lithium batteries, it is usually necessary to bend the battery's pole pieces (nickel sheets) so that the battery's pole pieces fit the positive and negative electrodes of the battery. In order to improve the bending efficiency of the battery pole pieces, most of the corresponding multi-station processing equipment will be used.

For example, a battery tab bending device with publication number CN116251870A includes a base and a processing platform, the processing platform is rotatably arranged above the base, and a rotating mechanism is arranged between the processing platform and the base; a number of processing boxes are fixedly installed around the top surface of the processing platform, each processing box has a bending mechanism on the top, each processing box has a fixing mechanism on both sides, and each processing box has a push-out mechanism on one side close to the center of the processing platform. By rotatably arranging the processing platform on the base, and providing a rotating mechanism for driving the processing platform to complete the rotation, and providing a processing box on the processing platform, and providing a bending mechanism, a fixing mechanism, and a push-out mechanism on the processing box, only two workers are needed to place the unprocessed workpiece and take out the processed workpiece respectively;

Among them, the above-mentioned prior art has the following technical problems: when the existing bending device bends the battery tabs, it is not convenient to clean the impurities attached to the positive and negative electrodes of the battery.

The attachment of impurities will also affect the welding quality between the two. At the same time, after the tabs are bent, it is not convenient to flatten the bent tabs, resulting in stress rebound in the battery pole pieces after bending, thereby affecting the bending quality and production efficiency.

Therefore, we propose a multi-station processing equipment for single-cell lithium batteries to solve the above problems.

In order to further solve this technical problem, this embodiment discloses the following technical content, as shown in Figures 5 to 9;

The two ends of the cleaning column 156 are sleeved with a leveling sleeve 158 on the outside, and the inner side of the leveling sleeve 158 is fixedly connected with a slide bar 159, and the end of the slide bar 159 away from the leveling sleeve 158 is inserted into the center rod 155, and the slide bar 159 is connected to the center rod 155 through the booster spring 1510, and the side of the slide bar 159 is fixedly connected with a vibration rod 1511, and the vibration rod 1511 is inserted into the inside of the cleaning column 156, and the outer ends of the two leveling sleeves 158 are fixedly connected with a magnetic ring 1512, and the side of the magnetic ring 1512 is provided with a movable ring 1513, which is installed on the fixed frame 154, and the movable ring 1513 is fixedly connected to the side of the magnetic ring 1512. The electromagnet 1514 is fixedly connected to the movable ring 1513 facing the magnetic ring 1512. The leveling sleeve 158 is symmetrically arranged with respect to the cleaning column 156, and the slide bar 159 fixedly connected to the inner side of the leveling sleeve 158 can slide on the center rod 155. There are multiple slide bars 159 evenly distributed at equal angles on the inner side of the leveling sleeve 158, and each slide bar 159 is fixedly connected to a vibration bar 1511, and one end of the vibration bar 1511 extending into the interior of the cleaning column 156 is initially in contact with the interior of the cleaning column 156. The movable ring 1513 can rotate on the fixed frame 154, and the electromagnet 1514 on the movable ring 1513 can generate a repulsive magnetic force on the magnetic ring 1512 on the leveling sleeve 158 after being energized.

After the electrode sheet is bent, the electromagnet 1514 on the movable ring 1513 is energized. After the electromagnet 1514 is energized, a repulsive magnetic force is generated on the magnetic ring 1512 on the leveling sleeve 158, so that the two leveling sleeves 158 move toward the center direction of the cleaning column 156 until the inner ends of the two leveling sleeves 158 contact each other. After the leveling sleeve 158 moves, the cleaning bristles 157 on the cleaning column 156 can be bent and deformed, so as to be stored in the inner side of the leveling sleeve 158. Thereafter, the horizontal plate 153 and the fixing frame 154 are controlled to move downward by adjusting the cylinder 152. After the fixing frame 154 moves downward, the flattening sleeve 158 can be pressed against the surface of the bent electrode sheet for rolling. When the rolling is completed, the electromagnet 1514 is de-energized. At this time, the flattening sleeve 15 8 is reset under the action of the assist spring 1510 interconnected between the slide bar 159 and the center rod 155. After the leveling sleeve 158 is reset, the cleaning bristles 157 inside it are also reset by their own elastic force. The impurities attached to the cleaning bristles 157 are shaken off by the shaking after the leveling sleeve 158 is reset. At the same time, when the leveling sleeve 158 moves toward the center direction of the center rod 155, the movement of the slide bar 159 can drive the vibration rod 1511 to move synchronously. When the leveling sleeve 158 and the slide bar 159 are reset, the vibration rod 1511 on the side of the slide bar 159 is also reset. Therefore, the vibration generated by the reciprocating movement of the vibration rod 1511 on the cleaning column 156 can further shake off the dust attached to the cleaning bristles 157, thereby ensuring the cleanliness of the cleaning bristles 157 itself.

The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
