Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a roller structure for manufacturing pole pieces of lithium ion batteries. Background Art

[0002] In the current lithium-ion battery manufacturing process, the pole piece needs to go through the unwinding-rewinding process, and during this process, a roller is needed to carry the pole piece. The roller is used in large quantities. During long-term use, the continuous movement of the pole piece will cause the roller surface to wear. In order to ensure product quality, the worn roller needs to be replaced regularly. The replacement process is to remove the worn roller and the roller mother frame from the equipment, then remove the worn roller from the roller mother frame, and install the new roller on the roller mother frame. This method requires subsequent horizontal calibration, which often takes about 6-8 hours, and all the worn rollers are scrapped, which increases costs. Utility Model Content

[0003] The utility model aims to solve the above technical problems and provides a roller structure for manufacturing pole pieces of lithium ion batteries.

[0004] According to the first aspect of the utility model, a roller structure for manufacturing pole pieces of a lithium-ion battery includes a roller mother component and a roller component, both of which are circular, and at least two limit blocks. The roller mother component is provided with a plurality of first slots, and the roller component is provided with a penetrating circular hole and a plurality of blocks. The roller component is sleeved on the roller mother component through the circular hole, the first slot is matched with the block, and the limit block is threadedly connected to the end of the roller mother component.

[0005] According to the roller structure for manufacturing pole pieces of lithium-ion batteries of the utility model, through the cooperation of the roller mother component and the roller child component, only the roller child component needs to be replaced after the roller child component is damaged, and there is no need to remove the roller mother component from the roller mother frame, thus saving replacement time, and the roller mother component can be reused, saving costs.

[0006] In a possible implementation of the first aspect, the limit block is provided with a screw rod, and the screw rod is threadedly connected to the end of the roller mother component. Specifically, the end of the roller mother component is provided with a threaded hole adapted to the screw rod.

[0007] In a possible implementation of the first aspect, the limit block is provided with a second slot that penetrates through it, and at least one block is provided at each end of the roller mother component. When the roller component needs to be replaced, the limit block is rotated counterclockwise so that the bottom of one side abuts against the block, and the limit block is in a vertical limit block state. Since the block is adapted to the first slot and there are multiple blocks, it is difficult to install it during installation. One end of a block on the roller component is placed in the second slot, and the limit block supports the roller component. When the block is placed in the second slot, the block can be quickly installed in the first slot.

[0008] In a possible implementation manner of the first aspect, both side edges of one end of the second card slot are beveled edges, so as to facilitate placement of one end of the card block in the second card slot.

[0009] In a possible implementation manner of the first aspect, the number of the first card slots and the number of the card blocks are both four. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] See also Figures 1 to 4As shown, this embodiment provides a roller structure for manufacturing pole pieces of lithium-ion batteries, which includes a roller mother component 10 and a roller component 2, both of which are circular, and at least two limit blocks 3. The roller mother component 10 is provided with a plurality of first slots 101, and the roller component 2 is provided with a through circular hole 201 and a plurality of blocks 202. The roller component 2 is sleeved on the roller mother component 10 through the circular hole 201, and the first slot 101 is matched with the block 202. The limit block 3 is threadedly connected to the end of the roller mother component 10.

[0021] The roller structure for manufacturing pole pieces of lithium-ion batteries according to the utility model is cooperated with the first slot 101 so that the roller component 2 and the roller mother component 10 will not rotate relative to each other when used in combination. After the surface of the roller component 2 is worn out after long-term use, the equipment is shut down, the entire roller structure is removed, the limit block 3 is rotated counterclockwise to keep it away from the roller component 2, and the roller component 2 is removed from the roller mother component 10. Then a new roller component 2 is installed, and the limit block 3 is rotated clockwise to limit the end of the roller component 2 to prevent it from moving. Through the cooperation of the roller mother component 10 and the roller component 2, after the roller component 2 is damaged, only the roller component 2 needs to be replaced, and there is no need to remove the roller mother component 10 from the roller mother frame, which saves replacement time, and the roller mother component 10 can be reused, saving costs.

[0022] It should be noted that the limit block 3 is provided with a screw rod 301 , and the screw rod 301 is threadedly connected to the end of the roller mother component 10 . Specifically, the end of the roller mother component 10 is provided with a threaded hole adapted to the screw rod 301 .

[0023] It should be noted that the limit block 3 is provided with a second slot 302 that penetrates through it, and at least one stop block 102 is provided at each end of the roller mother component 10. When the roller component 2 needs to be replaced, the limit block 3 is rotated counterclockwise so that the bottom of one side thereof abuts against the stop block 102, and the limit block 3 is in a vertical limit block 3 state. Since the block 202 is compatible with the first slot 101 and there are multiple blocks, it is difficult to install them during installation. One end of a block 202 on the roller component 2 is placed in the second slot 302, and the limit block 3 supports the roller component 2, and the block 202 is placed in the second slot 302, so that the block 202 can be quickly installed in the first slot 101.

[0024] It should be noted that both sides of one end of the second card slot 302 are beveled edges, so as to facilitate one end of the card block 202 to be placed in the second card slot 302 .

[0025] It should be noted that the number of the first card slots 101 and the number of the card blocks 202 are both four.

[0026] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
