[0040] A battery filling hole cleaning device includes a blowing assembly 1, which includes a first fixed rod 11, a first connecting block 13 is provided on the first fixed rod 11, a second fixed rod 12 is provided on the first connecting block 13, the second fixed rod 12 is perpendicular to the first fixed rod 11 and is staggered with the first fixed rod 11, a second connecting block is slidably provided on the first fixed rod 11, an air supply pipe 15 is provided on the second connecting block, the air supply pipe 15 has a cavity with one end open inside, the air supply pipe 15 is perpendicular to the second fixed rod 12 and is staggered with the second fixed rod 12, an air blowing nozzle 16 is provided at the end of the air supply pipe 15, the air blowing nozzle 16 is perpendicular to the air supply pipe 15, and the air blowing nozzle 16 has a blowing port 17, the air blowing port 17 is connected to the cavity, and an external air supply device is connected to the cavity.

[0041] Specifically, after the battery 5 has gone through the injection process, the residual electrolyte is placed in the injection hole of the battery 5. The battery 5 is placed under the blowing assembly 1, and the external air supply assembly blows high-pressure air to the injection hole of the battery 5 through the air supply pipe 15, the blowing nozzle 16 and the blowing port 17, so as to remove the residual electrolyte in the injection hole and prevent welding spatter and welds from being generated during welding. The air supply pipe 15 can be moved in the extension direction of the first fixed rod 11 through the first connecting block 13, and the height of the air supply pipe 15 can be changed. The blowing nozzle 16 is adjusted to an appropriate height to improve the efficiency of removing the electrolyte. The air supply pipe 15 can be adjusted in the width direction of the battery 5 through the second connecting block, and the height and width directions can be adjusted through the first fixed rod 11, the second fixed rod 12, the first connecting block 13 and the second connecting block, so that the present application can be used for batteries 5 of more sizes.

[0042] In this embodiment, a first through hole 131 and a second through hole 132 are provided on the first connection block 13. The first fixing rod 11 passes through the first through hole 131, and the first connection block 13 moves along the extending direction of the first fixing rod 11 through the first through hole 131. The second fixing rod 12 passes through the second through hole 132, and the second fixing rod 12 moves within the second through hole 132;

[0043] A third through hole 1 and a fourth through hole 2 are provided on the second connection block. The second connection block moves along the extending direction of the second fixing rod 12 through the third through hole 1. The air supply pipe 15 is slidably arranged within the fourth through hole 2, and the air supply pipe 15 moves within the fourth through hole 2.

[0044] Specifically, the first through hole 131 and the second through hole 132 on the first connection block 13 are perpendicular and non-intersecting, and the first connection block 13 is an integral body. The first through hole 131 on the first connection block 13 is used to connect the first connection block 13 with the first fixing rod 11. The first connection block 13 is sleeved on the first fixing rod 11 through the first through hole 131. A limiting hole is provided on one side of the first through hole 131, and the limiting hole communicates with the first through hole 131. A limiting member is arranged within the limiting hole. In this application, the limiting member is a screw (the limiting hole and the limiting member are conventional structures and will not be elaborated too much in this application). After the first fixing rod 11 is placed within the first through hole 131, the limiting member is tightened to position and fix the first connection block 13 to prevent the first connection block 13 from moving.

[0045] The bottom of the first fixing rod 11 is fixedly connected to the ground. In this application, the first fixing rod 11 supports the entire air blowing assembly 1.

[0046] The second fixing rod 12 passes through the second through hole 132. Different from the first fixing rod 11, the first fixing rod 11 itself cannot move, and the first connection block 13 moves along the extending direction of the first fixing rod 11. After the first connection block 13 is adjusted to a suitable height, the first connection block 13 is locked to prevent it from moving. The second fixing rod 12 can perform a circular motion with the first fixing rod 11 as the center. After the direction of the second fixing rod 12 is adjusted, the second fixing rod 12 is fixed by a limiting member in the same way as above.

[0047] After the second connection block is connected to the second fixing rod 12, the second connection block and the second fixing rod 12 are fixed through the third through hole 1 (the specific fixing method is the same as above and will not be elaborated too much here). The fourth through hole 2 is provided to accommodate the air supply pipe 15. The air supply pipe 15 can move within the fourth through hole 2. After the air supply pipe 15 is adjusted to a suitable position, it is fixed so that the air blowing nozzle 16 is directly opposite to the liquid injection hole of the battery 5.

[0048] The blowing component 1 can be adjusted in height, thickness, and angular direction through the first connecting block 13 and the second connecting block, further expanding the scope of use of the blowing component 1 and enabling operations on batteries 5 of multiple sizes.

[0049] In this embodiment, it includes a limiting component 2. The limiting component 2 includes a limiting plate 21 and limiting rollers 22. At least two limiting plates 21 are provided, and the two limiting plates 21 are arranged oppositely. The limiting rollers 22 are arranged on the inner sides of the two opposite limiting plates 21, and the limiting rollers 22 are movably connected to the limiting plates 21.

[0050] Specifically, the two limiting plates 21 are respectively arranged on both sides of the battery 5 in the thickness direction. The position of the battery 5 is fixed by the limiting plates 21 to prevent the battery 5 from running off course, which may cause the blowing nozzle 16 to miss the liquid injection hole of the battery 5. The residual electrolyte in the liquid injection hole can be better removed through the limiting plates 21.

[0051] When the limiting plate 21 limits the battery 5, the hard contact between the limiting plate 21 and the battery 5 may damage the outer shell of the battery 5. Therefore, limiting rollers 22 are arranged on the side of the limiting plate 21 opposite to the battery 5. A number of limiting rollers 22 are arranged along the length direction of the limiting plate 21, and the limiting rollers 22 can roll. The contact with the battery 5 is reduced through the limiting rollers 22, and at the same time, it is convenient for the battery 5 to move between the limiting plates 21.

[0052] In this embodiment, adjustment units 23 are arranged on one side of each of the two limiting plates 21. The adjustment unit 23 includes a first adjustment rod 231 and a second adjustment rod 232. The first adjustment rod 231 and the second adjustment rod 232 are connected through an adjustment block 233. The first adjustment rod 231 and the second adjustment rod 232 are perpendicular and staggered. The bottom end of the first adjustment rod 231 is fixedly arranged on the ground, and one end of the second adjustment rod 232 is fixedly connected to the limiting plate 21.

[0053] Specifically, the adjustment block 233 moves along the extension direction of the first adjustment rod 231, that is, the height of the limiting plate 21 is adjusted. The second adjustment rod 232 moves parallelly in the adjustment block 233, that is, the width of the limiting plate 21 is adjusted. One end of the second adjustment rod 232 is fixedly connected to the limiting plate 21. The limiting plate 21 is driven to move by moving the adjustment block 233 and the second adjustment rod 232.

[0054] Two adjustment units 23 are arranged at both ends of each limiting plate 21. The two adjustment units 23 are respectively arranged at both ends of the limiting plate 21 to support the limiting plate 21.

[0055] In this embodiment, a first adjustment hole 234 and a second adjustment hole 235 are provided on the adjustment block 233. The first adjustment rod 231 passes through the first adjustment hole 234, and the second adjustment rod 232 is disposed in the second adjustment hole 235. The first adjustment rod 231 and the second adjustment rod 232 move through the first adjustment and the second adjustment hole 235 respectively.

[0056] Specifically, the adjustment block 233 moves along the extending direction of the first adjustment rod 231 through the first adjustment hole 234, while the second adjustment rod 232 moves within the second adjustment hole 235. After the position is adjusted, the adjustment block 233 and the second adjustment rod 232 are fixed by the fixing method on the blowing assembly 1 to prevent them from moving. By adjusting the distance and height between the limiting plates 21, the limiting assembly 2 can limit and fix batteries 5 of different sizes, and more precisely remove the residual electrolyte.

[0057] In this embodiment, a wiping assembly 3 is further included. The wiping assembly 3 includes a fixing plate 31, a winding roller 32, a winding roller 33 and an abutting member 34 provided on the fixing plate 31. The abutting member 34 is disposed between the winding roller 32 and the winding roller 33. A wiping cotton towel 35 is sleeved between the winding roller 33 and the winding roller 32. The wiping cotton towel 35 is in a roll shape. The body of the wiping cotton towel 35 is placed on the winding roller 32, and the used wiping cotton towel 35 is wound onto the winding roller 33. The abutting member 34 abuts against the position of the wiping cotton towel 35 between the winding roller 32 and the winding roller 33.

[0058] Specifically, the wiping assembly 3 is disposed above the limiting assembly 2. When the blowing assembly 1 removes the electrolyte in the liquid injection hole of the battery 5, the residual electrolyte will be blown onto the surface of the battery 5. The wiping assembly 3 wipes the electrolyte on the upper surface of the battery 5. The specific working principle is as follows: After the battery 5 is blown, it moves to the lower part of the wiping assembly 3. Then, the abutting member 34 abuts against the wiping cotton towel 35 and moves towards the surface of the battery 5. The wiping cotton towel 35 contacts the surface of the battery 5. Then, the winding roller 33 winds up, and the wiping cotton towel 35 moves to wipe the residual electrolyte on the surface of the battery 5 clean. After the operation is completed, the abutting member 34 resets for the next operation.

[0059] In this embodiment, the abutting member 34 includes an abutting block 342 and an abutting cylinder 341. The abutting block 342 is fixedly arranged at the output end of the abutting cylinder 341. The abutting cylinder 341 is fixedly arranged on the fixing plate 31. The output end of the abutting cylinder 341 faces the battery 5, and the abutting block 342 is driven by the abutting cylinder 341 to move towards the battery 5.

[0060] Specifically, the structure of the cylinder is relatively simple and easy to maintain. The fixing plate 31 drives the abutting plate to move towards the battery 5 through the telescopic movement of the abutting cylinder 341, so as to realize the wiping function.

[0061] In this embodiment, the wiping assembly 3 includes a lifting unit 36. The lifting unit 36 is movably connected to the fixing plate 31. The lifting unit 36 includes a lifting rod 351 and a sliding block 352. The lifting rod 351 passes through the sliding block 352. The sliding block 352 is fixedly arranged on one side of the fixing plate 31. The lifting and lowering of the fixing plate 31 is realized by the sliding of the sliding block 352 and the lifting rod 351.

[0062] Specifically, in this application, operations are sometimes performed on batteries 5 with excessive or insufficient heights. In such cases, the wiping assembly 3 cannot wipe the surface of the battery 5. Therefore, the lifting unit 36 is provided. The fixing plate 31 is driven by the lifting unit 36 to move up and down, so that this application can operate on batteries 5 of multiple sizes. The specific working principle is as follows: When facing a battery 5 with a lower height, first place the battery 5 under the fixing plate 31 during machine adjustment. Adjust the lifting unit 36 to drive the fixing plate 31 to move downward. At the same time, control the abutting cylinder 341 to extend the output end of the abutting cylinder 341. When the abutting block 342 contacts the battery 5, stop descending and fix the lifting unit 36. At this time, the adjustment is completed. When facing a battery 5 with a higher height, first adjust the height of the fixing plate 31 as high as possible. Then control the output end of the abutting cylinder 341 to extend. Place the battery 5 under the fixing plate 31 and slowly lower the height of the fixing plate 31 until the abutting block 342 contacts the surface of the battery 5 and fix the lifting unit 36 to complete the adjustment.

[0063] Lifting units 36 are provided at both ends of the lifting unit 36. The fixing plate 31 is supported by the two lifting units 36, and the balance of the fixing plate 31 can also be adjusted.

[0064] In this embodiment, a driving member 37 is further provided on the fixing plate 31. The output end of the driving member 37 is in transmission connection with the winding roller 33, and the driving member 37 drives the winding roller 33 to rotate.

[0065] Specifically, the driving member 37 is arranged on the side of the fixing plate 31 facing away from the winding roller 33 and is fixedly connected to the fixing plate 31. Then the output end of the driving member 37 passes through the fixing plate 31 and is in transmission connection with the winding roller 33. The driving member 37 drives the winding roller 33 to perform a winding operation to wind up the used wiping cotton towel 35.

[0066] The driving member 37 can be a stepping motor, a servo motor or other driving members 37 that can perform driving.

[0067] In this embodiment, a conveying assembly 4 is further included. The conveying assembly 4 is arranged between the two limiting plates 21.

[0068] Specifically, the conveying component 4 includes a conveyor belt and a stepper motor. The stepper motor drives the conveyor belt 41 to move, and the distance of each movement of the conveyor belt 41 is the same. Through adjustment, the position of the battery 5 is accurately located below the blowing nozzle 16 and the wiping component 3.
