Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In the process of inspecting the appearance of battery cells, rotation is usually required to comprehensively inspect the cells, which relies on inspection fixtures with rollers. However, with increased use, the rollers of the inspection fixture accumulate dirt due to contact with substances on the cell surface and dust from the factory environment. This dirt may transfer to the cell surface during subsequent inspections, causing secondary contamination, which in turn affects the quality of the cells, impacts the inspection results, and leads to inaccurate or incomplete results. Therefore, cleaning and maintaining the rollers becomes a key factor in ensuring inspection quality and accuracy.

[0036] To address the cleanliness issue in the current battery cell testing process, the following section, in conjunction with the attached... Figure 1-2 The cleaning device of this application will be described in detail.

[0037] The cleaning device of this application is used for cleaning roller 91. The cleaning device of this application includes a roller brush 10 and an exhaust hood 20. The exhaust hood 20 includes an inlet 21 and an outlet 22. The roller brush 10 is disposed at the inlet 21. The roller brush 10 is axially rotatably fixed to the exhaust hood 20.

[0038] Specifically, when the roller 91 rotates, its movement drives the roller brush 10 to rotate, thereby cleaning the surface of the roller 91. During the cleaning process, the roller brush 10 effectively removes dust, dirt, or loose particles from the surface of the roller 91, while reducing the adhesion of more stubborn contaminants. The dust or particulate matter brushed off enters the exhaust hood 20 through the inlet 21, is discharged from the outlet 22 by the exhaust system, and is finally transported to the dust collection mechanism for centralized processing.

[0039] Through the synergistic action of the roller brush 10 and the extraction hood 20, continuous cleaning of the surface of the roller 91 can be achieved, avoiding the accumulation of dirt and secondary contamination of the battery cell by the roller 91. At the same time, the cleaning effect is further improved through the synergistic action of the roller brush 10 and the extraction hood 20.

[0040] In the above technical solution, the active cleaning of the roller brush 10 and the dust collection function of the exhaust hood 20 are combined to achieve dynamic cleaning and maintenance of the roller 91. This not only significantly improves the cleanliness of the roller 91 during the inspection process, but also effectively ensures the accuracy and stability of the cell appearance inspection. By reducing the risk of secondary contamination caused by surface contamination of the roller 91, this cleaning device can extend the equipment's operating cycle and reduce maintenance costs.

[0041] In addition, this cleaning device has a simple and compact structure, is easy to integrate into the battery cell appearance inspection system, and is suitable for cleaning needs of various roller diameters and surface materials, providing a reliable guarantee for the efficient operation of the equipment.

[0042] In some embodiments, the cleaning device of this application further includes a lifting mechanism 30. The lifting mechanism 30 is fixed to the suction hood 20 and is used to drive the suction hood 20 closer to or further away from the roller 91.

[0043] Specifically, the addition of the lifting mechanism 30 allows the height or position of the extraction hood 20 to be flexibly adjusted according to the diameter, surface condition, or degree of contamination of the roller 91. For example, when the surface of the roller 91 is heavily soiled, the lifting mechanism 30 can drive the extraction hood 20 closer to the roller to increase the cleaning pressure of the roller brush 10, thereby improving the cleaning effect. When the surface of the roller 91 is lightly soiled or the cleaning and maintenance cycle is short, the extraction hood 20 can be adjusted to an appropriate distance by the lifting mechanism 30 to reduce contact wear on the roller and extend the service life of the equipment. Of course, when cleaning is not being performed, the lifting mechanism 30 can raise the height of the extraction hood 20 so that the cleaning device does not affect the operation of the roller 91.

[0044] The lifting mechanism 30 can take several forms. For example, it can employ an electric screw design, where a motor drives the screw to rotate, thus achieving precise up-and-down movement of the extraction hood 20. This design offers advantages in high precision and automation, making it suitable for demanding clean environments. Alternatively, the lifting mechanism 30 can utilize a pneumatic device, such as a cylinder, to control the position of the extraction hood 20 using compressed air. This form offers fast response and a simple structure, making it suitable for scenarios requiring frequent adjustments. Another option is that the lifting mechanism 30 can consist of a slide rail and a slider, with the slider moved along the slide rail manually or electrically to achieve precise positioning of the extraction hood 20. This design is less expensive and suitable for small to medium-sized equipment. For scenarios requiring heavy loads or precise positioning, the lifting mechanism 30 can be hydraulically driven, using hydraulic oil pressure to control the lifting and lowering of the extraction hood 20. This form offers smooth operation and is suitable for high-load applications.

[0045] In this embodiment, the design of the lifting mechanism 30 significantly improves the flexibility and adaptability of the cleaning device. This technical solution can adjust the cleaning parameters according to the specific usage conditions of the roller 91, ensuring cleaning effectiveness while effectively reducing equipment wear. Simultaneously, the lifting mechanism can remain away from the roller when cleaning is not required, without affecting the roller's operation. Furthermore, the modular design of the lifting mechanism facilitates equipment maintenance and upgrades.

[0046] Therefore, the application of the lifting mechanism 30 not only enhances the flexibility of adjusting the distance between the exhaust hood 20 and the roller 91, but also broadens the application scope of the cleaning device, providing technical support for achieving multi-scenario and efficient roller cleaning.

[0047] In some embodiments, the lifting mechanism 30 is a cylinder.

[0048] Specifically, the lifting mechanism 30 is cylinder-driven, and its working principle is based on the control of compressed air. The lifting and lowering movement of the extraction hood 20 is achieved by adjusting the air pressure in the cylinder. Specifically, when compressed air is input into the working chamber of the cylinder, the cylinder piston rod will extend or retract under the action of air pressure, thereby driving the extraction hood 20 fixed on the cylinder to move closer to or away from the roller 91 in the vertical direction. This process is precisely adjusted through the cylinder control valve or air circuit system to meet different cleaning needs.

[0049] In the above technical solution, the cylinder is used as the lifting mechanism 30. The cleaning device of this application not only achieves efficient and precise lifting control, but also has the advantages of simple structure, easy maintenance and strong environmental adaptability. It provides stable and efficient power for the lifting of the exhaust hood 20 and the roller brush 10, ensuring the stability and operability of the cleaning device.

[0050] In some embodiments, the cleaning device of this application further includes a baffle 40, which is disposed inside the suction hood 20 and is parallel to the rotating shaft of the roller brush 10. The distance from the baffle 40 to the rotating shaft of the roller brush 10 is less than the outer radius of the roller brush 10. The angle α between the line connecting the baffle 40 and the rotating shaft of the roller brush 10 and the inlet 21 is greater than or equal to 45°. Figure 2 As shown.

[0051] Specifically, during operation, the cleaning device of this application rotates the roller 91, causing the roller brush 10 to rotate. As the roller brush 10 rotates, it contacts the baffle 40. Through physical friction and obstruction, the dust, dirt, or loose particles brushed off the roller brush 10 from the roller 91 are effectively removed. Thus, the dirt detached from the roller brush 10 is guided by the baffle 40 into the exhaust hood 20 and, through the negative pressure of the exhaust system, is sucked into the dust collection mechanism from the outlet 22 for centralized processing. The unique position and structural design of the baffle 40 prevents dust particles from falling back onto the surface of the roller 91, thereby reducing the risk of secondary pollution.

[0052] The angle α between the line connecting the baffle 40 and the rotating shaft of the roller brush 10 and the inlet 21 is greater than or equal to 45°. This design ensures that when dirt is subjected to suction force, it can smoothly detach from the surface of the roller brush 10 and enter the suction hood 20, without falling back onto the surface of the roller 91 due to rebound or gravity. By optimizing the angle α, the cleaning efficiency and suction effect are further improved.

[0053] Preferably, the contact surface between the roller brush 10 and the baffle 40 faces the outlet 22. This ensures that dirt is directly guided into the suction path by the baffle 40. This design reduces the risk of particles remaining or rebounding inside the suction hood, improving the smoothness of the cleaning process.

[0054] In the aforementioned technical solution, this application, through the ingenious design of the baffle 40, enhances the cleaning ability of the roller brush 10 while ensuring that dust particles smoothly enter the exhaust hood and are quickly discharged. This technical solution provides a reliable guarantee for the efficient cleaning of the roller 91 and further optimizes the overall operating performance of the equipment.

[0055] In some embodiments, there are two baffles 40, symmetrically distributed about the roller brush 10.

[0056] Specifically, during the operation of the cleaning device of this application, the roller 91 rotates to drive the roller brush 10 to rotate. When the roller brush 10 rotates, the dirt on its surface is effectively removed during the alternating contact with the two baffles 40. The symmetrically distributed baffles 40 can clean both sides of the roller brush 10 while it rotates, making the removal of dirt from the surface of the roller brush 10 more comprehensive and efficient.

[0057] Meanwhile, the symmetrically distributed baffles 40 can handle the roller brush 10 in different rotation directions, so that the roller brush 10 can be effectively cleaned whether it rotates clockwise or counterclockwise.

[0058] In the above technical solution, the symmetrical distribution of the baffles 40 makes the cleaning device more stable and improves the cleaning effect of the roller brush 10.

[0059] In some embodiments, the fume extractor 20 has a movable groove 23. The stop bar 40 can move along the movable groove 23. The distance from the distal end of the movable groove 23 to the axis of rotation of the roller brush 10 is greater than the outer radius of the roller brush 10.

[0060] The above technical solution provides greater flexibility, allowing the position of the baffle 40 to be changed according to the movement trajectory of the roller brush 10, adapting to different cleaning needs.

[0061] In some embodiments, the bristles of the roller brush 10 are radially distributed around the axis of rotation of the roller brush 10.

[0062] In the above technical solution, the radially distributed bristle design allows the bristles to act evenly on the surface of the roller 91, ensuring that each area is thoroughly cleaned.

[0063] This application provides a testing device, including a testing fixture 90 and the aforementioned cleaning device. The testing fixture 90 is provided with a rotatable roller 91, such as... Figure 3 As shown.

[0064] When the detection device of this application is in use, the rotation of the roller 91 drives the rotation of the roller brush 10, thereby cleaning the surface of the roller 91. During the cleaning process, the roller brush 10 can effectively remove dust, dirt, or loose particles from the surface of the roller 91, while reducing the adhesion of more stubborn contaminants. The dust or particulate matter brushed off enters the interior of the extraction hood 20 through the inlet 21, and is discharged from the outlet 22 by the action of the extraction system, and is finally transported to the dust collection mechanism for centralized treatment.

[0065] In the above technical solution, the testing device of this application can ensure the cleanliness of the testing fixture 90 during the testing process, thereby improving the stability of the battery cell testing effect.

[0066] In some embodiments, a movable track is also included, on which the detection fixture 90 is movably disposed. The number of rollers 91 is two or more.

[0067] Specifically, by sliding the testing fixture 90 on the moving track, the roller brush 10 cleans the rollers 91 on the testing fixture 90 in sequence.

[0068] In the above technical solution, multiple rollers 91 can be cleaned in turn, without increasing the number of cleaning devices.

[0069] This application provides a battery cell appearance inspection system, including an image acquisition device and the aforementioned inspection device. The inspection fixture 90 also includes a drive device for driving the roller 91 to rotate.

[0070] In the above technical solution, the battery cell appearance inspection system of this application ensures the cleanliness of the equipment during the inspection process through a self-cleaning inspection device, thereby improving the accuracy of the inspection.

[0071] The above technical solutions are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
