Description

Technical Field

[0001] This utility model belongs to the field of lithium battery production technology, and more specifically, it relates to a device for dust removal treatment of lithium batteries. Background Technology

[0002] Lithium-ion batteries are a type of rechargeable battery. They are commonly used in portable electronic products and electric vehicles, and are increasingly popular in military and aerospace applications. Existing dust removal devices for lithium batteries use clamps to hold the battery in place, and then use high-pressure gas to clean the dust from the outside of the battery. However, the high-pressure gas cannot reach the contact area between the clamp and the battery, creating blind spots in the cleaning process. Therefore, a new device for dust removal from lithium batteries is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a device for dust removal from lithium batteries. After cleaning the battery, the other two sides are clamped first, and then the clamped sides are released, so that areas blocked by the clamps can also be cleaned. This solves the problem of existing dust removal devices for lithium batteries mentioned in the background art, which use clamps to fix the battery and then use high-pressure gas to clean the dust on the outside of the lithium battery. However, the high-pressure gas cannot reach the contact area between the clamps and the battery, resulting in blind spots in the cleaning process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for dust removal from lithium batteries, comprising a housing, multiple spray pipes fixed inside the housing, and multiple nozzles on the outer sides of each spray pipe. Two fixing plates are fixed to the bottom inner side of the housing, and a mounting bracket is fixed between the two fixing plates. Four sliding grooves are formed on the outer side of the mounting bracket, and connecting plates are slidably connected between opposite sliding grooves. A baffle is fixed to the top surface of the connecting plate, and two guide rods are slidably connected inside the baffle. A clamping plate is fixed to one end of each guide rod, and a spring is fixed between the clamping plate and the baffle. A mounting base is fixed to the outer side of the mounting frame, and a motor is fixed to the outer side of the mounting base. The output end of the motor passes through the interior of the mounting base and is coaxially fixed to a turntable. A limit ring is fixed to one side of the turntable, and a groove is formed on one side of the limit ring. Multiple gear teeth are formed on the inner side of the groove. A first gear, a second gear, and a third gear are rotatably connected to the inner side of the mounting base. One end of the shaft of the first gear and the third gear passes through the interior of the mounting base and is coaxially fixed to a roller. Two annular grooves are formed on the outer side of the rollers, and a slider is slidably connected to the inner side of the annular grooves. One end of the slider is fixedly connected to one end of a connecting plate.

[0005] As a preferred embodiment of this utility model, the mounting frame consists of four mounting plates arranged in a rectangular pattern.

[0006] As a preferred technical solution of this utility model, the outer circumference of the first gear slides in contact with the outer circumference of the limiting ring, and the outer circumference of the first gear also meshes with the outer circumference of the gear teeth for transmission.

[0007] As a preferred embodiment of this utility model, the outer circumference of the second gear slides in contact with the outer circumference of the limiting ring, and the outer circumference of the second gear also meshes with the outer circumference of the gear teeth for transmission.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a device for dust removal from lithium batteries, including a housing 1. Multiple spray pipes 2 are fixed inside the housing 1, and multiple nozzles 3 are provided on the outer sides of each spray pipe 2. Two fixing plates 4 are fixed to the bottom inner side of the housing 1, and a mounting bracket 5 is fixed between the two fixing plates 4. Four sliding grooves 6 are opened on the outer side of the mounting bracket 5, and connecting plates 7 are slidably connected between opposite sliding grooves 6. A baffle 8 is fixed to the top surface of the connecting plate 7, and two guide rods 9 are slidably connected inside the baffle 8. A clamping plate 10 is fixed to one end of each guide rod 9, and a spring 11 is fixed between the clamping plate 10 and the baffle 8. A mounting base 12 is also fixed to the outer side of the mounting bracket 5, and a motor 13 is fixed to the outer side of the mounting base 12. The output end of the motor 13 passes through the interior of the mounting base 12 and is coaxially fixed to a turntable 14. A limit ring 15 is fixed to one side of the turntable 14, and a groove is opened on one side of the limit ring 15. Multiple gear teeth 16 are provided inside the groove. The mounting base 12... The inner side of the mounting bracket 5 is rotatably connected to a first gear 17, a second gear 18, and a third gear 19. One end of the shaft of the first gear 17 and the third gear 19 passes through the interior of the mounting base 12 and is coaxially fixed to a roller 20. Two annular grooves 21 are opened on the outer side of the roller 20. A slider 22 is slidably connected to the inner side of the annular groove 21. One end of the slider 22 is fixedly connected to one end of the connecting plate 7. The mounting bracket 5 consists of four mounting plates arranged in a rectangular shape. The outer circumference of the first gear 17 slides in contact with the outer side of the limiting ring 15. The outer circumference of the first gear 17 also meshes with the outer side of the gear tooth 16. The outer circumference of the second gear 18 slides in contact with the outer side of the limiting ring 15. The outer circumference of the second gear 18 also meshes with the outer side of the gear tooth 16. The annular groove 21 has an inclined structure. The second gear 18 and the third gear 19 are meshed together. Two fixed seats are rotatably connected to the outer side of the shaft of the roller 20. One end of the fixed seat is fixedly connected to the outer side of the mounting bracket 5.

[0023] Motor 13 drives turntable 14 to rotate, which in turn drives limit ring 15 and gear teeth 16 to rotate. During this process, because the distance between the center of limit ring 15 and the center of the first gear 17 and the second gear 18 is less than the radius of the first gear 17 and the second gear 18, when the gear teeth 16 come into contact with the limit ring 15, the gap between the two teeth of the first gear 17 and the second gear 18 gets stuck on the limit ring 15, preventing the first gear 17 and the second gear 18 from rotating. When gear teeth 16 come into contact with the first gear 17 and the second gear 18, the teeth on the first gear 17 and the second gear 18 are just aligned. The battery falls into the groove, providing sufficient space for movement. Driven by the gear teeth 16, the battery rotates. The gear teeth 16 sequentially drive the first gear 17 and the second gear 18 to rotate half a turn intermittently, thereby driving the two rollers 20 to rotate half a turn intermittently. During this process, the annular groove 21 on the rollers 20 drives the slider 22 and the connecting plate 7 to move relative to or in opposite directions, so that the clamping plate 10 fixes or releases the battery. This allows the battery to be cleaned by first clamping the other two sides and then releasing the two sides that were originally clamped, so that the areas blocked by the clamps can also be cleaned, thus avoiding the phenomenon of dead corners.

[0024] The specific usage and function of this embodiment: This utility model uses a motor 13 to drive a turntable 14 to rotate, and the turntable 14 drives a limiting ring 15 and gear teeth 16 to rotate. During this process, because the distance between the limiting ring 15 and the center of the first gear 17 and the second gear 18 is less than the radius of the first gear 17 and the second gear 18, when the gear 16 contacts the limiting ring 15, the gap between the two teeth of the first gear 17 and the second gear 18 gets stuck on the limiting ring 15, preventing the first gear 17 and the second gear 18 from rotating. When the gear teeth 16 contact the first gear 17 and the second gear 18, the first gear 17 and the second gear 18... The teeth on gear 17 and the second gear 18 fall into the groove, providing sufficient room for movement. Driven by the gear tooth 16, they rotate. The gear tooth 16 sequentially drives the first gear 17 and the second gear 18 to rotate half a turn intermittently, thereby driving the two rollers 20 to rotate half a turn intermittently. During this process, the annular groove 21 on the roller 20 drives the slider 22 and the connecting plate 7 to move relative to or in opposite directions, so that the clamping plate 10 fixes or releases the battery. This allows the other two sides to be clamped first after the battery is cleaned, and then the two sides that were originally clamped to be released, so that the areas blocked by the clamp can also be cleaned.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
