[0040] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0041] The present embodiment relates to a battery cell cleaning device, which is beneficial to improving the efficiency of battery cell cleaning operations and ensuring the stability of battery cells after gluing before module stacking. At the same time, it can reduce the number of plasma cleaning heads 22 installed, achieve cost-saving design, and thus have a better use effect.

[0042] In terms of overall structure, Figures 1 to 8 As shown, the battery cell cleaning device of this embodiment includes a battery cell conveying line and a battery cell cleaning mechanism. The battery cell conveying line is used to convey the battery cells along a preset conveying path.

[0043] In addition, battery cell cleaning mechanisms are respectively provided on both sides of the preset conveying path, and the battery cell cleaning mechanisms on each side include a first driving unit 3, and a plasma cleaning unit 2 connected to the driving end of the first driving unit 3, and the first driving unit 3 can drive the plasma cleaning unit 2 to rise and fall, and the plasma cleaning unit 2 is used to clean the battery cells.

[0044] In specific implementation, the battery cell cleaning device of this embodiment also includes a workbench 1, and a frame 11 supported on the bottom of the workbench 1. The above-mentioned battery cell conveying line and battery cell cleaning mechanism are both arranged on the top of the workbench 1, and the related structural parts not mentioned in the battery cell cleaning device of this embodiment can all refer to the battery cell cleaning equipment familiar to technical personnel in this field. For example, a plurality of battery cell trays are provided on the battery cell conveying line, and the battery cells to be cleaned are vertically placed on the battery cell trays.

[0045] Also, see Figure 3 As shown, the directional words used in the embodiment, such as "up, down, left, right, front, and back", are defined based on the up and down direction (also called the height direction, or the Z direction of the workbench 1), the left and right direction (also called the width direction, or the Y direction of the workbench 1), and the front and back direction (also called the length direction, or the X direction of the workbench 1) of the workbench 1. In this embodiment, the lifting and lowering of the plasma cleaning part 2 is the lifting and lowering along the height direction of the workbench 1. In addition, as a preferred implementation form, the preset conveying path of this embodiment is arranged along the width direction of the workbench 1.

[0046] Based on the above overall introduction, in this embodiment, as a preferred implementation form, Figure 4 As shown, the battery cell cleaning mechanism on each side includes a second driving part 4 and a first mounting seat 5 driven to move by the second driving part 4 , and the first driving part 3 and the plasma cleaning part 2 are arranged on the first mounting seat 5 .

[0047] Thus, the distance between the plasma cleaning section 2 and the battery cell to be cleaned can be adjusted, thereby increasing the cleaning range of the plasma cleaning section 2 and being suitable for cleaning operations of battery cells of different models. At the same time, it is beneficial to reduce the number of plasma cleaning heads 22 arranged in the plasma cleaning section 2, thereby achieving cost-saving design.

[0048] Specifically, in this embodiment, as a preferred implementation form, a base plate 81 is provided on the first mounting seat 5, the first driving part 3 is fixed on the base plate 81, the plasma cleaning part 2 is slidably provided on the base plate 81, and the plasma cleaning part 2 is connected to the driving end of the first driving part 3. The advantage of such a setting is that it is conducive to realizing the lifting design of the plasma cleaning part 2.

[0049] At the same time, in the specific implementation, as a preferred implementation form, in this embodiment, combined with Figure 2 and Figure 5 As shown in , the first mounting seat 5 is provided with a second mounting seat 8 and a third driving unit 7 for driving the second mounting seat 8 to move. The substrate 81 is provided on the second mounting seat 8, and the moving direction of the second mounting seat 8 is perpendicular to the moving direction of the first mounting seat 5.

[0050] It can be understood that the coordination between the third driving unit 7 and the second mounting seat 8 can not only cooperate with the second driving unit 4 and the first mounting seat 5, but can further increase the cleaning range of the plasma cleaning unit 2, which is suitable for cleaning operations of different types of battery cells and is conducive to cost reduction design. At the same time, the second mounting seat 8 is arranged vertically to the moving direction of the first mounting seat 5, which can also make the plasma cleaning unit 2 close to or away from the battery cell, thereby realizing the plasma cleaning unit 2 entering or exiting the cleaning position 14, which is conducive to equipment maintenance and replacement of parts.

[0051] In this embodiment, if necessary, the second mounting seat 8 may further be provided with a reinforcing plate 82 for reinforcing the mounting strength of the base plate 81, for example Figure 6 As shown, reinforcing plates 82 are respectively provided on both sides of the substrate 81 in the width direction to ensure the structural stability between the substrate 81 and the second mounting seat 8 .

[0052] Moreover, during specific implementation, the moving direction of the second mounting seat 8 of this embodiment is preferably the width direction of the workbench 1, and the moving direction of the first mounting seat 5 is preferably the length direction of the workbench 1. At the same time, the third driving unit 7 of this embodiment can adopt a linear guide rail well known to those skilled in the art. This can improve the accuracy of driving the plasma cleaning unit 2 to move left and right during battery cell cleaning, thereby ensuring the quality of cleaning.

[0053] For example, the third driving unit 7 can adopt a servo motor, and a guide rail extending along the width direction of the workbench 1 is set on the first mounting seat 5, the second mounting seat 8 slides on the guide rail, and the servo motor is connected to the second mounting seat 8 through a ball screw, etc.

[0054] Secondly, the second driving part 4 of this embodiment can preferably adopt a cylinder, and the first mounting seat 5 is slidably arranged on the workbench 1 along the length direction of the workbench 1, and the cylinder rod of the cylinder is connected to the first mounting seat 5 to drive the first mounting seat 5.

[0055] At this time combined Figure 3 As shown, the workbench 1 of this embodiment is provided with a cleaning position 14 located in the middle of the length direction of the workbench 1, and installation positions 13 arranged on both sides of the cleaning position 14, the installation position 13 is used to install the battery cell cleaning mechanism, and during specific implementation, the battery cell conveying line body conveys the battery cell tray with the battery cells to be cleaned to the cleaning position 14, and the battery cell cleaning mechanisms on both sides can drive the plasma cleaning part 2 to approach the cleaning position 14 through the cooperation of the second driving part 4 and the third driving part 7 (the second driving part 4 drives the plasma cleaning part 2 to move along the length direction of the workbench 1, and the third driving part 7 drives the plasma cleaning part 2 to move along the width direction of the workbench 1), and clean both sides of the battery cell with the cooperation of the first driving part 3 (driving the plasma cleaning part 2 along the height direction of the workbench 1).

[0056] In addition, in this embodiment, as a preferred implementation form, Figure 5 As shown, the plasma cleaning part 2 includes a plasma cleaning head 22 slidably disposed on a substrate 81, and a dust cover 23 for covering at least a portion of the plasma cleaning head 22. With such a configuration, an operation mode of cleaning and removing dust from the battery cell can be realized, so as to improve the battery cell cleaning quality and ensure the overall cleanliness of the battery cell cleaning device.

[0057] It is worth mentioning that the dust removal components related to the dust hood 23 not mentioned in this embodiment can refer to the relevant dust removal equipment known to technical personnel in this field. For example, the dust hood 23 is preferably connected to an external dust collection host through a dust removal pipe 231, and the dust collection host can be, for example, a fan.

[0058] At the same time, the part of the dust removal duct 231 of this embodiment close to the dust removal cover 23 can be set on one of the reinforcing plates 82 through a support rod 84, and the support rod 84 is preferably arranged along the height direction of the workbench 1 to prevent the dust removal duct 231 from shaking during the battery cell cleaning operation, and even affecting the normal progress of the cleaning operation, thereby improving the stability of the device.

[0059] In specific implementation, as a preferred implementation form, in this embodiment, combined with Figure 5 and Figure 8 As shown, the plasma cleaning head 22 is slidably disposed on the base plate 81 through the bottom plate 21 , and an adjustment plate 24 with adjustable position is disposed on the bottom plate 21 , and the plasma cleaning head 22 is disposed on the adjustment plate 24 .

[0060] By adjusting the position of the adjustment plate 24 relative to the base plate 21, the relative position of the plasma cleaning head 22 and the base plate 21 can be fine-tuned on the basis of lifting and lowering, thereby facilitating the adjustment of the cleaning position of the plasma cleaning head 22 and facilitating the development and implementation of the battery cell cleaning operation.

[0061] Among them, in order to realize the implementation form in which the position of the adjustment plate 24 and the base plate 21 is adjustable, a long hole can be set on the adjustment plate 24, and the extension direction of the long hole is set according to the actual fine-tuning requirements. Then, the bolt is passed through the long hole and screwed into the screw hole on the base plate 21. When adjusting, first loosen the bolt, then adjust the position of the adjustment plate 24, and finally tighten the bolt to realize the position adjustment of the adjustment plate 24 and the base plate 21.

[0062] Furthermore, refer to Figure 8 As shown, in order to improve the convenience of adjustment, a scale 211 can be set on the base plate 21, and a pointer 241 can be set on the adjustment plate 24. The advantage of such a setting is that the accuracy and efficiency of fine-tuning can be improved. However, it should be noted that the extension direction of the above-mentioned long holes is set to be the same as the extension direction of the scale 211. For example, the scale 211 is set on the top edge of the base plate 21, and the long holes are parallel to the top edge of the base plate 21.

[0063] At the same time, in this embodiment, as a preferred implementation form, the plasma cleaning heads 22 are arranged in sequence along the lifting direction of the plasma cleaning part 2. Therefore, the efficiency of the battery cell cleaning operation can be improved by combining the lifting design thereof.

[0064] In specific implementation, the lifting direction of the plasma cleaning part 2 of this embodiment is the height direction of the workbench 1, and the plasma cleaning head 22 is preferably set to two that are lifted and lowered along the height direction of the workbench 1, so as to ensure the cleaning efficiency of the battery cells while reducing the number of plasma cleaning heads 22 used, thereby reducing the overall manufacturing cost of the device.

[0065] In addition, in this embodiment, as a preferred implementation form, Figure 6 and Figure 7 As shown, the first driving part 3 includes a lifting cylinder arranged on a base plate 81 , a cylinder rod of the lifting cylinder is connected to the bottom plate 21 through a connecting member 31 , and an avoidance hole 811 for avoiding the connecting member 31 is provided on the base plate 81 .

[0066] In detail, the lifting cylinder and the base plate 21 are arranged on both sides of the base plate 81. The lifting cylinder is installed on the base plate 81 through the mounting plate 83. The base plate 21 is slidably set on the base plate 81 through the lifting slider 813 on the lifting slide rail 812, and the cylinder rod of the lifting cylinder is connected to the connecting part 31 through the floating joint 32 to achieve a better linkage effect and reduce the chance of damage to the lifting cylinder.

[0067] Secondly, to facilitate the connection of the connecting member 31 to the base plate 21 and the cylinder rod, the connecting member 31 may preferably be L-shaped, so as to have a first portion parallel to and connected to the base plate 21 , and a second portion connected to the cylinder rod via a floating joint 32 .

[0068] Of course, the number and arrangement of the mounting plates 83, lifting rails 812 and lifting sliders 813 can be set and adjusted according to the actual installation requirements of the lifting cylinder and the actual sliding requirements of the base plate 21. For example, there are two mounting plates 83 arranged at intervals along the height direction of the workbench 1, and there are two lifting rails 812 arranged on both sides of the avoidance hole 811 (both extending along the height direction of the workbench 1), and there are two lifting sliders 813 sliding on each lifting rail 812, etc.

[0069] Furthermore, in this embodiment, as a preferred implementation form, Figure 7 As shown, a buffer 6 is provided on the base plate 81, and the buffer 6 is used to buffer the impact force at the connecting member 31. At the same time, as a preferred implementation form, a limiter 25 is provided on the base plate 81, and the limiter 25 is used to limit the rising height of the connecting member 31.

[0070] The advantage of such a setting is that it can cooperate with the lifting cylinder to achieve accurate positioning of the plasma cleaning head 22 when cleaning the battery cell. In the specific structure, the buffer 6 and the limiter 25 can be installed on the base plate 81 through the mounting block 85, and the limiter 25 can be bolted to facilitate the adjustment of the limit position, thereby cooperating with the buffer 6 to achieve a better limit effect.

[0071] In addition, in this embodiment, as a preferred implementation form, Figure 1 As shown, it also includes a protective cover 12 covering the workbench 1, and the battery cell conveying line body and each battery cell cleaning mechanism are located in the protective cover 12, thereby realizing protection of the battery cell cleaning device.

[0072] Furthermore, in this embodiment, as a preferred implementation form, the protective cover 12 is made of a transparent plate, which is convenient for the staff to observe the overall movement of the device, thereby facilitating the normal operation of the device and ensuring the quality of battery cell cleaning.

[0073] Specifically, the transparent plate of this embodiment can be an acrylic plate. At the same time, in order to ensure the structural strength of the protective cover 12, the protective cover 12 also includes a main frame made of sheet metal, and the transparent plate is arranged on the main frame. In this way, the purpose of safety protection can be achieved while intuitively seeing the movement of the device.

[0074] The battery cell cleaning device of the present embodiment can realize that both sides of the battery cell can be cleaned simultaneously by respectively arranging battery cell cleaning mechanisms on both sides of the preset conveying path, which is beneficial to improving the cleaning operation efficiency and ensuring the stability of the battery cell after gluing before module stacking. At the same time, by arranging the first driving part 3 to drive the plasma cleaning part 2 to rise and fall, it is also possible to achieve full coverage of the large surface of the battery cell during battery cell cleaning, reduce the number of installed plasma cleaning heads 22, and be beneficial to realizing cost reduction design, thereby helping to meet the production design requirements of module products.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
