Description

Technical Field

[0001] This invention relates to the field of new energy lithium battery technology, specifically a cleaning device for new energy lithium battery production and its usage method. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode material and a non-aqueous electrolyte solution. Lithium-ion batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, the lithium metal battery, was developed in 1996, and its safety, specific capacity, self-discharge rate, and performance-price ratio are all superior to lithium-ion batteries. Due to its high technical requirements, only companies in a few countries produce this type of lithium metal battery.

[0003] The specific steps in the battery manufacturing process include positive electrode slurry drawing, negative electrode slurry drawing, positive electrode sheet, negative electrode sheet, steel shell assembly, electrolyte injection and testing, and packaging. Before packaging, lithium batteries need to go through multiple processes. During this process, dust may adhere to the lithium battery electrodes and need to be cleaned. When in use, lithium batteries need to be arranged neatly in multiple groups, and then the corresponding electrodes are connected in sequence. The dimensional error of lithium batteries is relatively large, which will affect the neatness when multiple groups are arranged, and it is not convenient to connect the electrodes. The separate testing of lithium batteries before assembly increases the complexity of the process. Summary of the Invention

A support spring is sleeved on the outer wall of the scale rod. One end of the support spring is fixedly connected to the upper surface of the cleaning box, and the other end of the support spring is fixedly connected to the outer wall of the scale rod.

[0011] Specifically, a rotating box is fixedly connected to the outer wall of the rotating shaft. The rotating box is spoon-shaped and includes an arc-shaped concave bottom and a protruding guide plate. A groove is formed at the connection between the arc-shaped concave bottom and the protruding guide plate.

[0012] Specifically, an upper arc-shaped cover is fixedly connected to the outer wall of the rotating shaft, and a gap is left between the end of the upper arc-shaped cover away from the rotating shaft and the protruding guide plate.

[0013] Specifically, an arc-shaped spring is fixedly connected to the side of the rotating box near the inner wall of the cleaning box, and the end of the arc-shaped spring away from the rotating box is fixedly connected to the inner wall of the cleaning box.

[0014] Specifically, side guide plates are fixedly connected to the inner walls of both side mounting plates, and sliding grooves are opened on the opposite sides of the two side guide plates on the same side. A guide protrusion is provided at the end of the cleaning box, and the guide protrusion is slidably connected in the sliding groove. An electrically controlled push rod is fixedly connected to the top of the mounting frame, and the telescopic end of the electrically controlled push rod is fixedly connected to the top of the cleaning box.

[0015] Specifically, a support ring is fixedly connected to the top of the cleaning box, and a rotating ball is rotatably connected to the middle of the support ring. A nozzle is fixedly connected to one end of the rotating ball inside the cleaning box. The nozzle is made of a soft material.

[0016] Specifically, a high-pressure air pump is fixedly connected to the top of the cleaning box, and an air guide pipe is fixedly connected to the output end of the high-pressure air pump. The air guide pipe is fixedly connected to the rotating ball, away from the high-pressure air pump.

[0017] Specifically, a drive motor is fixedly connected to the top center of the cleaning box, and an arc-shaped rod is fixedly connected to the output end of the drive motor.

[0018] Specifically, each of the two air guide tubes has a connecting sleeve fitted at one end of the rotating ball, and a connecting block is fixedly connected to the opposite side of the two connecting sleeves. A connecting groove is opened on the side of the connecting block away from the connecting sleeve. A transmission rod is rotatably connected between the two connecting grooves. A threaded limiting shaft is rotatably provided at one end of the transmission rod placed inside the connecting groove. A rotating disk is fixedly connected to the middle of the transmission rod. An eccentric hole is opened on the surface of the rotating disk, and the arc-shaped rod is inserted into the eccentric hole.

[0019] A method for using a cleaning device for new energy lithium battery production includes the following steps:

[0020] S1: First, place the lithium battery to be cleaned onto the conveyor belt. As the conveyor belt moves, it will bring the lithium battery to the bottom of the cleaning box. The inner wall of the side mounting plate is equipped with a position sensor. When the lithium battery moves to the bottom of the cleaning box, the conveyor belt stops moving. The telescopic end of the electric control push rod begins to extend and push the cleaning box downward. During the downward movement of the cleaning box, the high-pressure air pump starts to work. The high-pressure gas enters the rotating ball through the air guide pipe and is then sprayed out through the nozzle set at the bottom of the rotating ball.

[0021] S2: Turn on the drive motor. The output end of the drive motor drives the arc rod to rotate. During the rotation of the arc rod, the rotating disk shakes regularly. The rotating disk also drives the connected transmission rod to shake. The connecting block connected to the end of the transmission rod drives the connecting sleeve to shake. The connecting sleeve pulls the rotating ball to rotate, so that it can rotate along the inner wall of the support ring.

[0022] S3: Under the action of the top of the lithium battery, both sets of rotating boxes will rotate at a certain angle along the rotating shaft. When the rotating shaft rotates, it can wind up the pull rope, and the upper end of the pull rope pulls the bottom of the scale rod downward.

[0023] S4: After the lithium battery is cleaned, the electronically controlled push rod moves upward to the initial position. The conveyor belt continues to drive the cleaned lithium battery to the next station. At this time, the cleaning brush at the bottom of the cleaning box will clean the surface of the lithium battery again.

[0024] The beneficial effects of this invention are:

[0025] (1) The cleaning device for the production of new energy lithium batteries and its usage method described in this invention, wherein the rotating shaft can wind up the pull rope when rotating, and the upper end of the pull rope pulls the bottom of the scale rod downward, and the length and width error of the lithium battery is judged by the distance the scale rod moves downward.

[0026] (2) The cleaning device and its usage method for the production of new energy lithium batteries described in this invention use high-pressure gas to blow the dirt on the surface of the lithium battery to both sides, where it falls onto the upper surface of the upper arc-shaped cover or the protruding guide plate, and then slides into the interior of the arc-shaped concave bottom for collection. The upper arc-shaped cover facilitates the concentration of dirt and also prevents dirt that has entered the protruding guide plate from being blown out by the gas.

[0027] (3) The cleaning device and its usage method for the production of new energy lithium batteries described in this invention rotates the ball so that it can rotate along the inner wall of the support ring, so that the gas sprayed from the nozzle covers a wider range, which is more conducive to cleaning the top of the lithium battery and the motor connecting column. The nozzle is made of soft material and can deform when it comes into contact with the electrode connecting column of the lithium battery, thus avoiding scratching the electrode connecting column.

[0028] (4) The cleaning device and its usage method for the production of new energy lithium batteries described in this invention, wherein the connecting sleeve pulls the rotating ball to rotate, thereby rotating along the inner wall of the support ring, so that the gas sprayed from the nozzle covers a wider range, which is more conducive to cleaning the top of the lithium battery and the motor connecting column.

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0043] like Figures 1-8 As shown, the cleaning device for new energy lithium battery production according to the present invention includes a side mounting plate 1.

[0044] Mounting bracket 11, the side mounting plate 1 is fixedly mounted on the top of the side mounting plate 1;

[0045] Guide rail 13, the guide rail 13 is fixedly installed on the bottom inner side of the mounting bracket 11;

[0046] Limiting rotating wheels 14, and multiple limiting rotating wheels 14 are rotatably connected to opposite sides of two guide rails 13;

[0047] Conveyor belt 12, which is disposed below guide rail 13, and lithium battery 7 is placed on the upper surface of conveyor belt 12;

[0048] A cleaning assembly 2 is slidably disposed between the two side mounting plates 1. The cleaning assembly 2 includes a cleaning box 21, and a soft cleaning brush 211 is installed at the bottom of each cleaning box 21. A side collection member 26 is rotatably connected to the inner wall of the cleaning box 21. The side collection member 26 includes a rotating shaft 261, and a pull rope 231 is wound around the end of the rotating shaft 261. Multiple scale rods 23 are slidably disposed through the top of the cleaning box 21. The bottom of the scale rods 23 is fixedly connected to the upper end of the pull rope 231. A support spring 24 is sleeved on the outer wall of the scale rods 23. One end of the support spring 24 is fixedly connected to the upper surface of the cleaning box 21, and the other end of the support spring 24 is fixedly connected to the outer wall of the scale rods 23.

[0049] The side mounting plate 1 serves as a limit, the conveyor belt 12 can intermittently transport the lithium battery 7, the cleaning box 21 can clean the lithium battery 7 and collect dirt, and the size of the lithium battery 7 can be measured in time during the cleaning process to ensure that the size error of the lithium battery 7 is within the preset range.

[0050] Under the action of the top of the lithium battery 7, both sets of rotating boxes 262 will rotate at a certain angle along the rotating shaft 261. When the rotating shaft 261 rotates, it can wind up the pull rope 231. The upper end of the pull rope 231 pulls the bottom of the scale rod 23 downward. The length and width error of the lithium battery 7 is judged by the distance the scale rod 23 moves downward. For example, if the size of the lithium battery 7 is too large, it will push the rotating box 262 to rotate at an increased angle, and the distance the scale rod 23 moves downward will be greater than the preset distance.

[0051] Specifically, a rotating box 262 is fixedly connected to the outer wall of the rotating shaft 261. The rotating box 262 is spoon-shaped and includes an arc-shaped concave bottom 2621 and a protruding guide plate 2622. A groove is formed at the connection between the arc-shaped concave bottom 2621 and the protruding guide plate 2622.

[0052] As the cleaning box 21 moves downward, the rotating box 262 placed inside the cleaning box 21 moves downward synchronously. The end of the protruding guide plate 2622 of the rotating box 262 will contact the side wall of the lithium battery 7. As the protruding guide plate 2622 slides down along the outer wall of the lithium battery 7, it can clean the outer wall of the lithium battery 7 and scrape off the dirt attached to the outer wall of the lithium battery 7.

[0053] Specifically, an upper arc-shaped cover 263 is fixedly connected to the outer wall of the rotating shaft 261, and a gap is left between the end of the upper arc-shaped cover 263 away from the rotating shaft 261 and the protruding guide plate 2622.

[0054] High-pressure gas blows dirt from the surface of the lithium battery 7 to both sides, where it falls onto the upper surface of the upper arc-shaped cover 263 or the protruding guide plate 2622, and then slides into the interior of the arc-shaped concave bottom 2621 for collection. The upper arc-shaped cover 263 facilitates the collection of dirt and also prevents dirt that has entered the protruding guide plate 2622 from being blown out by the gas.

[0055] Specifically, an arc-shaped spring 264 is fixedly connected to the side of the rotating box 262 near the inner wall of the cleaning box 21, and the end of the arc-shaped spring 264 away from the rotating box 262 is fixedly connected to the inner wall of the cleaning box 21.

[0056] As the rotating box 262 rotates upward, the arc spring 264 will be stretched. After the rotating box 262 separates from the outer wall of the lithium battery 7, the rotating box 262 will rotate back to the initial position under the push of the arc spring 264.

[0057] Specifically, the inner walls of the two side mounting plates 1 are fixedly connected with side guide plates 15, and the opposite sides of the two side guide plates 15 on the same side are provided with sliding grooves. The end of the cleaning box 21 is provided with a guide protrusion 22, which is slidably connected in the sliding groove. The top of the mounting bracket 11 is fixedly connected with an electric push rod 4, and the telescopic end of the electric push rod 4 is fixedly connected to the top of the cleaning box 21.

[0058] The guide protrusion 22 and the sliding groove are designed to make the cleaning box 21 move more smoothly and steadily. At the same time, the movement of the cleaning box 21 can be controlled by the electric push rod 4.

[0059] Specifically, a support ring 25 is fixedly connected to the top of the cleaning box 21, and a rotating ball 64 is rotatably connected to the middle of the support ring 25. A nozzle 65 is fixedly connected to one end of the rotating ball 64 inside the cleaning box 21. The nozzle 65 is made of soft material.

[0060] The rotating ball 64 rotates along the inner wall of the support ring 25, allowing the gas sprayed from the nozzle 65 to cover a wider area, which further facilitates the cleaning of the top of the lithium battery 7 and the motor connecting post. The nozzle 65 is made of soft material and can deform when it comes into contact with the electrode connecting post of the lithium battery 7, thus avoiding scratching the electrode connecting post.

[0061] Specifically, a high-pressure air pump 6 is fixedly connected to the top of the cleaning box 21, and an air guide pipe 61 is fixedly connected to the output end of the high-pressure air pump 6. The air guide pipe 61 is fixedly connected to the rotating ball 64 away from the high-pressure air pump 6.

[0062] As the cleaning box 21 moves downwards, the high-pressure air pump 6 starts to work. High-pressure gas enters the rotating ball 64 through the air guide pipe 61, and then is sprayed out through the nozzle 65 set at the bottom of the rotating ball 64 to clean the top of the lithium battery 7 and the top electrode connection post, ensuring the cleanliness of the lithium battery 7 during packaging.

[0063] Specifically, a drive motor 31 is fixedly connected to the top center of the cleaning box 21, and an arc-shaped rod 32 is fixedly connected to the output end of the drive motor 31.

[0064] Each of the two air guide tubes 61 has a connecting sleeve 36 fitted at one end of the rotating ball 64. A connecting block 35 is fixedly connected to the opposite side of each of the two connecting sleeves 36. A connecting groove 351 is opened on the side of the connecting block 35 away from the connecting sleeve 36. A transmission rod 34 is rotatably connected between the two connecting grooves 351. A threaded limiting shaft 352 is rotatably provided at one end of the transmission rod 34 placed inside the connecting groove 351. A rotating disk 33 is fixedly connected to the middle of the transmission rod 34. An eccentric hole 331 is opened on the surface of the rotating disk 33. The arc-shaped rod 32 is inserted into the eccentric hole 331.

[0065] When the drive motor 31 is turned on, its output drives the arc-shaped rod 32 to rotate. During this rotation, the arc-shaped rod 32 drives the rotating disk 33 to oscillate regularly. Simultaneously, the rotating disk 33 drives the connected transmission rod 34 to oscillate. Through the connecting block 35 connected to the end of the transmission rod 34, the connecting sleeve 36 oscillates. The connecting sleeve 36 pulls the rotating ball 64 to rotate, allowing it to rotate along the inner wall of the support ring 25. This makes the gas sprayed from the nozzle 65 cover a wider area, further facilitating the cleaning of the top of the lithium battery 7 and the motor connecting column.

[0066] A method for using a cleaning device for new energy lithium battery production, characterized by comprising the following steps:

[0067] S1: First, place the lithium battery 7 to be cleaned onto the conveyor belt 12. As the conveyor belt 12 moves, it will bring the lithium battery 7 to the bottom of the cleaning box 21. The inner wall of the side mounting plate 1 is equipped with a position sensor. When the lithium battery 7 moves to the bottom of the cleaning box 21, the conveyor belt 12 stops moving. The telescopic end of the electric control push rod 4 begins to extend and push the cleaning box 21 downward. As the cleaning box 21 moves downward, the high-pressure air pump 6 starts to work. The high-pressure gas enters the rotating ball 64 through the air guide pipe 61 and is then sprayed out through the nozzle 65 set at the bottom of the rotating ball 64.

[0068] S2: Turn on the drive motor 31. The output end of the drive motor 31 drives the arc rod 32 to rotate. During the rotation, the arc rod 32 drives the rotating disk 33 to shake regularly. The rotating disk 33 simultaneously drives the connected transmission rod 34 to shake. The connecting block 35 connected to the end of the transmission rod 34 drives the connecting sleeve 36 to shake. The connecting sleeve 36 pulls the rotating ball 64 to rotate, so that it can rotate along the inner wall of the support ring 25.

[0069] S3: Under the action of the top of the lithium battery 7, both sets of rotating boxes 262 will rotate at a certain angle along the rotating shaft 261. When the rotating shaft 261 rotates, it can wind up the pull rope 231. The upper end of the pull rope 231 pulls the bottom of the scale rod 23 downward.

[0070] S4: After the lithium battery 7 is cleaned, the electronically controlled push rod 4 moves upward. Once the initial position is reached, the conveyor belt 12 continues to drive the cleaned lithium battery 7 to the next station. At this time, the cleaning brush 211 at the bottom of the cleaning box 21 will clean the surface of the lithium battery 7 again.

[0071] Working principle: The lithium battery 7 to be cleaned is placed on the conveyor belt 12. As the conveyor belt 12 moves, it will bring the lithium battery 7 to the bottom of the cleaning box 21. The inner wall of the side mounting plate 1 is equipped with a position sensor (existing technology). When the lithium battery 7 moves to the bottom of the cleaning box 21, the conveyor belt 12 stops moving. At the same time, the telescopic end of the electric control push rod 4 begins to extend and push the cleaning box 21 downward. During the downward movement of the cleaning box 21, the high-pressure air pump 6 starts to work. The high-pressure gas enters the rotating ball 64 through the air guide pipe 61 and is then sprayed out through the nozzle 65 set at the bottom of the rotating ball 64. The top of the lithium battery 7 and the top electrode connection post are cleaned to ensure the cleanliness of the lithium battery 7 during packaging.

[0072] When the drive motor 31 is turned on, its output drives the arc-shaped rod 32 to rotate. During this rotation, the arc-shaped rod 32 drives the rotating disk 33 to oscillate regularly. Simultaneously, the rotating disk 33 drives the connected transmission rod 34 to oscillate. Through the connecting block 35 connected to the end of the transmission rod 34, the connecting sleeve 36 oscillates. The connecting sleeve 36 pulls the rotating ball 64 to rotate, allowing it to rotate along the inner wall of the support ring 25. This makes the gas sprayed from the nozzle 65 cover a wider area, further facilitating the cleaning of the top of the lithium battery 7 and the motor connecting column.

[0073] As the cleaning box 21 moves downward, the rotating box 262 placed inside the cleaning box 21 moves downward synchronously. The end of the protruding guide plate 2622 of the rotating box 262 will contact the side wall of the lithium battery 7. As the protruding guide plate 2622 slides down along the outer wall of the lithium battery 7, it can clean the outer wall of the lithium battery and scrape off the dirt attached to the outer wall of the lithium battery 7.

[0074] Under the action of the top of the lithium battery 7, both sets of rotating boxes 262 will rotate at a certain angle along the rotating shaft 261. When the rotating shaft 261 rotates, it can wind up the pull rope 231. The upper end of the pull rope 231 pulls the bottom of the scale rod 23 downward. The length and width error of the lithium battery 7 is judged by the distance the scale rod 23 moves downward. For example, if the size of the lithium battery 7 is too large, it will push the rotating box 262 to rotate at an increased angle, and the distance the scale rod 23 moves downward will be greater than the preset distance.

[0075] High-pressure gas blows dirt from the surface of the lithium battery 7 to both sides, where it falls onto the upper surface of the upper arc-shaped cover 263 or the protruding guide plate 2622, and then slides into the interior of the arc-shaped concave bottom 2621 for collection. The upper arc-shaped cover 263 facilitates the collection of dirt and also prevents dirt that has entered the protruding guide plate 2622 from being blown out by the gas.

[0076] After the lithium battery 7 is cleaned, the electronically controlled push rod 4 moves upward. Once it reaches the initial position, the conveyor belt 12 continues to drive the cleaned lithium battery 7 to the next station. At this time, the cleaning brush 211 at the bottom of the cleaning box 21 will clean the surface of the lithium battery 7 again to ensure that the electrode connection posts of the lithium battery 7 are clean before packaging.

[0077] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.

9. A cleaning device for new energy lithium battery production and its method of use according to claim 8, characterized in that: One end of the rotating ball (64) close to the two air pipes (61) is fitted with a connecting sleeve (36). The opposite sides of the two connecting sleeves (36) are fixedly connected with connecting blocks (35). The side of the connecting block (35) away from the connecting sleeve (36) is provided with a connecting groove (351). A transmission rod (34) is rotatably connected between the two connecting grooves (351). One end of the transmission rod (34) placed inside the connecting groove (351) is rotatably provided with a threaded limiting shaft (352). A rotating disk (33) is fixedly connected to the middle of the transmission rod (34). An eccentric hole (331) is provided on the surface of the rotating disk (33). The arc rod (32) is inserted into the eccentric hole (331).

10. The method of using the cleaning device for new energy lithium battery production according to claim 9, characterized in that: Includes the following steps: S1: First, place the lithium battery (7) to be cleaned on the conveyor belt (12). During the movement of the conveyor belt (12), the lithium battery (7) will be brought to the bottom of the cleaning box (21). The inner wall of the side mounting plate (1) is equipped with a position sensor. When the lithium battery (7) moves to the bottom of the cleaning box (21), the conveyor belt (12) stops moving. The telescopic end of the electric control push rod (4) begins to extend and push the cleaning box (21) downward. During the downward movement of the cleaning box (21), the high-pressure air pump (6) starts to work. The high-pressure gas enters the rotating ball (64) through the air guide pipe (61) and then sprays out through the nozzle (65) set at the bottom of the rotating ball (64). S2: Turn on the drive motor (31). The output end of the drive motor (31) drives the arc rod (32) to rotate. During the rotation, the arc rod (32) drives the rotating disk (33) to shake regularly. The rotating disk (33) simultaneously drives the connected transmission rod (34) to shake. The connecting block (35) connected to the end of the transmission rod (34) drives the connecting sleeve (36) to shake. The connecting sleeve (36) pulls the rotating ball (64) to rotate, so that it can rotate along the inner wall of the support ring (25). S3: Under the action of the top of the lithium battery (7), both sets of rotating boxes (262) will rotate at a certain angle along the rotating shaft (261). When the rotating shaft (261) rotates, it can wind up the pull rope (231). The upper end of the pull rope (231) pulls the bottom of the scale rod (23) downward. S4: After the lithium battery (7) is cleaned, the electric control push rod (4) moves upward. Once the initial position is reached, the conveyor belt (12) continues to drive the cleaned lithium battery (7) to the next station. At this time, the cleaning brush (211) at the bottom of the cleaning box (21) will clean the surface of the lithium battery (7) again.
