Description

Technical Field

[0001] This utility model relates to the field of battery cell processing technology, specifically to a deburring fixture for processing lithium battery cells. Background Technology

[0002] During the production of lithium batteries, burrs may be generated on the electrode sheets of the battery cells during die-cutting and slitting. If these burrs are not effectively removed, they may puncture the separator used to separate the positive and negative electrode sheets, leading to an internal short circuit in the battery. This can cause battery leakage, affecting battery performance and lifespan; in severe cases, it may trigger a battery explosion, posing a serious threat to personnel and property safety. Therefore, deburring the battery cells is a crucial step in ensuring the safe and reliable operation of lithium batteries.

[0003] During the manufacturing process of cylindrical battery cells, burrs may be generated on the electrode sheets during processes such as punching and winding. These burrs not only affect the appearance quality of the battery cell, but more importantly, they may cause internal short circuits, leading to safety issues such as decreased battery performance, leakage, or even explosion.

[0004] Utility model application CN202220465676.8 relates to the field of lithium battery production equipment technology, and particularly to a deburring device for the skirt of a lithium battery cell. The device includes a clamping assembly for clamping the cell, at least one grinding assembly, and a driving assembly for moving the grinding assembly along the skirt of the cell. It also includes a detection assembly facing the cell and used to detect burrs on the skirt. The grinding assembly grinds the burrs on the cell skirt, ensuring they are within acceptable limits. The detection assembly measures and positions the burrs on the clamping assembly, and the driving assembly then drives the grinding assembly to grind the burrs. This improves the accuracy of burr removal, ensuring the quality of subsequent cell production. Furthermore, it achieves efficient deburring, increasing production efficiency. Compared to manual deburring with sandpaper or brushes, the combination of the grinding assembly and the detection assembly achieves high precision and efficiency, resulting in excellent burr removal.

[0005] The aforementioned patent detects the battery cell during the grinding process, but it cannot adaptively clamp the battery cell. As a result, the battery cell cannot be completely ground to the clamping position during the deburring process, leading to incomplete grinding of the battery cell.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0027] like Figures 1 to 7 As shown, a deburring fixture for processing lithium battery cells includes: a housing 1, a moving component 2, a grinder 4, and a transmission component 5.

[0028] During the manufacturing process of cylindrical battery cells, burrs may be generated on the electrode sheets during processes such as punching and winding. These burrs not only affect the appearance quality of the battery cell, but more importantly, they may cause internal short circuits, leading to safety issues such as decreased battery performance, leakage, or even explosion.

[0029] The moving component 2 includes a moving guide rail 21, a fixed disk 54, a limiting frame 23, a first gear 24, and a pulley 25. The moving guide rail 21 is fixedly connected to the fixed disk 54, and the fixed disk 54 is rotatably connected to the first gear 24. The limiting frame 23 is fixedly connected to the moving guide rail 21. The first gear 24 has two sets, and the two sets of first gears 24 are connected by the pulley 25. A drive source is also fixedly connected to the side of the first gear 24. The first gear 24 can rotate freely on the fixed disk 54 without changing its position. The limiting frame 23 is used to ensure that the moving component does not exceed the predetermined range of motion. The drive source (such as a motor, reducer, etc.) is also fixedly connected to the side of the first gear 24. This means that the power generated by the drive source is directly transmitted to the first gear 24, and then transmitted to the other set of gears through the pulley 25. This is used to adjust the position of the deburring device to fine-tune the deburring position of the battery cell.

[0030] The movable guide rail 21 is also slidably connected to a mounting bracket 3, which is fixedly connected to the grinding head 45. When the movable guide rail 21 is driven (e.g., by a motor, cylinder or other drive mechanism), it moves along its designed path. Since a sliding connection is established between the mounting bracket 3 and the movable guide rail 21, the mounting bracket 3 (and the grinding head 45 fixedly connected to it) also moves with the movable guide rail 21, so that the grinding head 45 can move precisely and controllably on the surface to be ground, thereby achieving efficient positioning and deburring of the battery cell.

[0031] The grinder 4 consists of a first spring 41, a fixed block 42, a transmission rod 43, a second spring 44, a grinding head 45, and a grinding disc 46. The first spring 41 is fixedly connected to the transmission rod 43, the transmission rod 43 is slidably connected to the fixed block 42, the transmission rod 43 is fixedly connected to the second spring 44, the other end of the second spring 44 is fixedly connected to the grinding head 45, and the grinding head 45 is fixedly connected to the grinding disc 46. When the grinder 4 is subjected to external force (e.g., by manual pressing or mechanical drive), the first spring 41 and the second spring 44 will be compressed or stretched. This deformation of the springs will cause the transmission rod 43 to slide within the fixed block 42. The sliding of the transmission rod 43 will further cause the second spring 44 to extend or retract, thereby transmitting force or motion to the grinding head 45. The grinding head 45 moves accordingly and drives the grinding disc 46 to grind the target surface.

[0032] The transmission assembly 5 includes a drive cylinder 51, a mounting plate 52, a rotary motor 53, a fixed disk 54, a transmission wheel 55, a second gear 56, a clamp 57, and a limiter 58. The drive cylinder 51 is fixedly connected to the mounting plate 52, the mounting plate 52 is connected to the fixed disk 54 via a pin, the fixed disk 54 is fixedly connected to the rotary motor 53, the output shaft of the rotary motor 53 is fixedly connected to the transmission wheel 55, the second gear 56 has a cylinder extending from its bottom, and the transmission wheel 55 is connected to the cylinder extending from the bottom of the second gear 56 via a belt. The second gear 56 is provided with... There are multiple sets of gears that mesh with each other. The limiter 58 is fixedly connected to the output end of the drive cylinder 51. The piston rod movement of the cylinder is directly transmitted to the mounting plate 52, allowing the mounting plate 52 to rotate or swing relative to the fixed plate 54 to a certain extent. The rotational movement of the motor is directly transmitted to the transmission wheel 55. This belt drive allows a certain distance between the transmission wheel 55 and the second gear 56, while realizing the transmission of power. Multiple sets of second gears 56 mesh with each other to form a gear transmission system for transmitting and converting rotational movement. The limiter 58 ensures that the cylinder stops moving when it reaches the predetermined position.

[0033] The clamp 57 consists of a chuck 571, a third spring 572, and a clamping plate 573. The chuck 571 is fixedly connected to the third spring 572, and the third spring 572 is fixedly connected to the clamping plate 573. When an external force is applied to the chuck 571 or the clamping plate 573, the third spring 572 will deform and store energy. When the external force disappears, the spring will release energy, causing the chuck 571 and the clamping plate 573 to return to their original positions. When the third spring 572 deforms, the clamping plate 573 will move accordingly, thereby clamping or releasing the battery cell to perform deburring operations on the battery cell.

[0034] Working principle:

[0035] The first gear 24 can rotate freely on the fixed plate 54 without changing its position. The limit bracket 23 is used to ensure that the moving parts do not exceed the predetermined range of motion. The first gear 24 is also fixedly connected to a drive source (such as a motor, reducer, etc.), which means that the power generated by the drive source is directly transmitted to the first gear 24, and then transmitted to another set of gears through the pulley 25. When the grinder 4 is subjected to external force (e.g., by manual pressing or mechanical drive), the first spring 41 and the second spring 44 will be compressed or stretched. This deformation of the springs will cause the transmission rod 43 to slide in the fixed block 42. The piston rod movement of the cylinder will be directly transmitted to the mounting plate 52, allowing the mounting plate 52 to rotate or swing relative to the fixed plate 54 to a certain extent. The rotational movement of the motor will be directly transmitted to the transmission wheel 55. This belt drive method allows a certain distance between the transmission wheel 55 and the second gear 56, while realizing the transmission of power. Multiple sets of second gears 56 mesh with each other to form a gear transmission system for transmitting and converting rotational motion. The limit bracket 58 ensures that the cylinder stops moving when it reaches the predetermined position.
