[0036] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] refer to Figures 1 to 4 The cleaning device provided by the utility model integrates detection, positioning and cleaning functions, including a turntable mechanism 1, a feeding mechanism 2, a cleaning mechanism 3 and a first unloading mechanism 4 are arranged in sequence on the periphery of the turntable mechanism 1, and a detection and positioning mechanism 5 is provided on the feeding path of the feeding mechanism 2. In the process of the feeding mechanism 2 clamping the battery cell from the previous station to the turntable mechanism 1, the detection and positioning mechanism 5 detects and positions the battery cell. After the battery cell is placed on the turntable mechanism 1, the cleaning and unloading of the battery cell are completed in sequence as the turntable mechanism 1 rotates.

[0040] Specifically, the detection and positioning mechanism 5 includes a visual detection unit 51, which is used to perform appearance detection and position calculation on the battery cell. In some embodiments, the visual detection unit 51 can be a CCD industrial camera, the lens of the CCD industrial camera faces upward, and performs appearance detection on the lower surface of the battery cell, for example, detecting the position or size of the L-shaped glue attached to the lower surface of the battery cell. A ring light can be set around the lens of the CCD industrial camera for fill light to improve the quality and efficiency of visual detection.

[0041] During the process of the feeding mechanism 2 feeding the battery cell, the visual inspection unit 51 first performs an appearance inspection on the battery cell, then calculates the position of the battery cell and sends a signal to the feeding mechanism 2. After receiving the signal, the feeding mechanism 2 adjusts the position of the battery cell so that the battery cell can be placed on the turntable mechanism 1 with an accurate position, thereby achieving accurate alignment and cleaning of the subsequent battery cell, and ensuring the quality and efficiency of the cleaning operation. The positioning of the battery cell is achieved through the cooperation of the visual inspection unit 51 and the feeding mechanism 2, which not only has higher positioning accuracy, but also high positioning efficiency. The visual inspection unit 51 can simultaneously realize the detection and positioning functions, effectively improving the operating efficiency of the battery cell production, while achieving quality control of the battery cell production link, and high production quality.

[0042] As a further optimization, the feeding mechanism 2 includes a feeding manipulator 21 and a feeding unit 22 connected to the driving end of the feeding manipulator 21. In some embodiments, the feeding manipulator 21 may be a four-axis robot, which can adjust the position of the battery cell through its own rotating axis, and the feeding unit 22 may be provided with an adsorption component to absorb and fix the battery cell.

[0043] As a further optimization, the turntable mechanism 1 includes a rotary drive unit 11 and a rotary disk 12 connected to the driving end of the rotary drive unit 11, and the rotary disk 12 is provided with a plurality of battery cell fixing platforms 13 at equal intervals along the circumference direction. As one embodiment, the number of battery cell fixing platforms 13 is three, and when the first battery cell fixing platform 13 is located at the loading station, the second battery cell fixing platform 13 is just located at the cleaning station, and the third battery cell fixing platform 13 is located at the unloading station, so that loading, cleaning, and unloading operations can be carried out simultaneously, and the battery cell production efficiency is high.

[0044] In some embodiments, the cell fixing platform 13 may be provided with multiple cell fixing positions, preferably two, each of which is provided with a cell, and the cell fixing position may be provided with an adsorption component to fix the cell, and a glue layer may be provided on the contact surface between the cell fixing position and the cell to avoid scratching the cell and protect the cell. Providing multiple cell fixing positions can realize cleaning and unloading operations on two cells at the same time, further improving the efficiency of cell production operations.

[0045] Example 2

[0046] As a further optimization of Example 1, refer to Figures 5 and 6 The cleaning mechanism 3 includes a moving module 31 and a plasma cleaning unit 32 connected to the driving end of the moving module 31. The moving module 31 is used to drive the plasma cleaning unit 32 to move back and forth in the horizontal direction. The plasma cleaning unit 32 is located above the rotating disk 12. In some embodiments, the number of the plasma cleaning unit 32 is one. The plasma cleaning unit 32 moves horizontally under the drive of the moving module 31, and cleans the upper surface of the battery cell during the horizontal movement.

[0047] In some embodiments, the plasma cleaning unit 32 may need to clean two battery cells at the same time. During the one-way movement of the plasma cleaning unit 32, it will pass over the two battery cells in sequence, thereby cleaning the two battery cells, eliminating the need to set up a plasma cleaning unit 32 and reducing production costs.

[0048] Furthermore, the cleaning mechanism 3 also includes a purge unit 33, which is located below the plasma cleaning unit 32 and is used to purge the position to be cleaned on the surface of the battery cell. In some embodiments, the purge unit 33 includes an air blow pipe, and when the battery cell is located at the cleaning station, the air blow pipe is located above the side of the battery cell, and the debris or foreign matter at the position to be cleaned of the battery cell is removed by the purge action of the air blow pipe, and then the plasma cleaning unit 32 cleans the upper surface of the battery cell. The pre-cleaning purge of the purge unit 33 is conducive to improving the cleanliness and cleaning efficiency of the subsequent plasma cleaning operation, thereby improving the quality and efficiency of the cleaning operation.

[0049] Furthermore, the cleaning mechanism 3 also includes a cleaning protective member 34, which is located below the purge unit 33 and is used to isolate the protective plate on the battery cell from the plasma cleaning unit 32. In some embodiments, the cleaning protective member 34 is fixed in position. When the battery cell reaches the cleaning station under the rotation of the turntable mechanism 1, the cleaning protective member 34 is just located above the battery cell protective plate and completely covers the battery cell protective plate, thereby isolating the battery cell protective plate from the plasma cleaning unit 32. Since plasma cleaning operations are not suitable for battery cell protective plates, the provision of the cleaning protective member 34 can well isolate the battery cell protective plate from the plasma cleaning unit 32, thereby preventing the battery cell protective plate from being interfered with or damaged, and ensuring the normal performance of the battery cell.

[0050] Furthermore, the cleaning mechanism 3 also includes a pushing and clamping unit 35, which is located below the cleaning protection member 34. The pushing and clamping unit 35 includes a driving member 351 and a pushing and clamping block 352 connected to the driving end of the driving member 351, and the pushing and clamping block 352 is used to push and clamp the tail soft board of the protection plate. In some embodiments, the driving member 351 includes a front and rear driving cylinder and a left and right driving cylinder. The front and rear driving cylinders are used to drive the pushing and clamping block 352 to move toward the direction of the tail soft board of the protection plate, and the left and right driving cylinders are used to drive the pushing and clamping block 352 to push and clamp the tail soft board of the protection plate. A buffer spring can be provided between the pushing and clamping block 352 and the driving ends of the left and right driving cylinders. The buffer spring can play a buffering role in the process of the pushing and clamping block 352 pushing and clamping the tail soft board of the protection plate, so as to avoid excessive pushing and clamping of the pushing and clamping block 352 and causing damage to the battery cell or the protection plate.

[0051] Since the tail soft board of the protection board is open in a natural state, the push-clamp unit 35 can confine the tail soft board of the protection board to a fixed area to avoid interference with the cleaning operation by the tail soft board of the protection board, while also achieving the unification of the position of the tail soft board of the protection board of each battery cell.

[0052] Example 3

[0053] As a further optimization of Example 1, refer to Figures 7 to 10 , a code scanning mechanism 6 is also provided between the cleaning mechanism 3 and the first unloading mechanism 4. It should be noted that the code scanning mechanism 6 and the first unloading mechanism 4 are both located at the unloading station. When the battery cell reaches the unloading station under the rotation of the turntable mechanism 1, the code scanning mechanism 6 first scans and binds the battery cell, and then the first unloading mechanism 4 unloads the battery cell. Since the code scanning mechanism 6 and the first unloading mechanism 4 are located at the same station, the movement of the battery cell between the code scanning mechanism 6 and the first unloading mechanism 4 is omitted, thereby improving the production efficiency of the battery cell.

[0054] In some embodiments, the cleaning device integrating detection, positioning and cleaning functions further includes a second unloading mechanism 7 and a transfer platform 8, and the transfer platform 8 is located between the first unloading mechanism 4 and the second unloading mechanism 7. As one embodiment, the first unloading mechanism 4 includes a first horizontal moving module and a first unloading unit connected to the driving end of the first horizontal moving module, and the first unloading unit is provided with a rotating cylinder, which can realize the azimuth conversion of the unloading battery cell; the second unloading mechanism 7 includes a second horizontal moving module and a second unloading unit connected to the driving end of the second horizontal moving module, and the driving direction of the first horizontal moving module is perpendicular to the driving direction of the second horizontal moving module, and the transfer platform 8 is located at the junction of the first unloading mechanism 4 and the second unloading mechanism 7. The specific implementation process is that the first unloading unit picks up the battery cell from the turntable mechanism 1 and rotates the battery cell 90 degrees. The first unloading unit moves to the position of the transfer platform 8 under the drive of the first horizontal movable module and places the battery cell on the transfer platform 8. The second unloading unit picks up the battery cell from the transfer platform 8 and unloads the battery cell to the next workstation under the drive of the second horizontal movable module.

[0055] As a further optimization, the cleaning device integrating detection, positioning and cleaning functions also includes a flip mechanism 9, which is located on one side of the feeding mechanism 2. In some embodiments, the flip mechanism 9 includes a flip drive unit and a flip plate, one end of the flip plate is connected to the driving end of the flip drive unit, and the other end is provided with a battery core suction block, which can be used to absorb the battery core. The flip mechanism 9 can absorb the battery core of the previous station and flip it 180 degrees for the feeding mechanism 2 to load.

[0056] The utility model integrates detection, positioning and cleaning functions into one cleaning device. By setting a visual detection unit, it realizes the detection of battery cells before cleaning operations, ensures production quality and high operating efficiency. The visual detection unit has detection and positioning functions at the same time, which not only improves the operating efficiency, but also has high positioning accuracy, ensuring the quality of subsequent cleaning operations. By setting a number of battery cell fixing platforms, loading, cleaning and unloading operations can be carried out simultaneously, and the operating efficiency is high. The provision of a purge unit is conducive to further improving the cleaning quality and efficiency. The provision of a cleaning protective piece can protect the battery cell protection board during the cleaning operation to ensure the normal performance of the battery cell. The provision of a push-clamp unit can realize the fixation and unification of the position of the soft board at the tail of the protection board.
