[0038] In this embodiment, a battery box cleaning device mainly includes an ultrasonic cleaning chamber 100, a conveying mechanism 130, a box opening cleaning mechanism 140, and a feeding mechanism 180.

[0039] The ultrasonic cleaning chamber 100 is used to clean the battery box. The ultrasonic cleaning chamber 100 has an inlet 110 and an outlet 120 on opposite sides.

[0040] The conveying mechanism 130 passes through the inlet 110 and the outlet 120. The conveying mechanism 130 is used to convey the battery box with the opening facing down through the ultrasonic cleaning chamber 100.

[0041] In this embodiment, by having the conveying mechanism 130 convey the battery box with its opening facing downwards through the ultrasonic cleaning chamber 100, the cleaning fluid can be prevented from entering the battery box from the opening and remaining inside the battery box, which is beneficial for subsequent drying operations.

[0042] In some specific embodiments, the conveying mechanism 130 includes two conveying chains 230 arranged side by side, a plurality of support plates 240 arranged along the conveying direction of the conveying mechanism 130, and a limiting component 250 disposed on the support plate 240. The two ends of the support plate 240 are respectively connected to the two conveying chains 230. The support plate 240 is used to support the battery box, and the limiting component 250 is used to insert into the opening of the battery box to limit the battery box. Thus, fixing the opening downwards can prevent the cleaning fluid from flowing back, and the limiting component 250 can prevent the battery box from moving and falling under force during the cleaning process. In this way, the conveying of the battery box during the cleaning process is more stable.

[0043] Specifically, the limiting component 250 includes four pins, which limit the inner walls of the four corners of the battery box respectively. Thus, the four corner pins limit the risk of the battery box torsion. At the same time, the multi-point contact can disperse stress and prevent the thin-walled battery box from deforming.

[0044] Furthermore, the top of the pin has a guide cone 260, which enables the pin to self-align with the box opening, reducing positioning time. At the same time, the cone angle design of the guide cone 260 can prevent scratching the inner wall of the box opening.

It can be understood that ultrasonic cleaning and box opening brushing are carried out in steps to prevent aluminum shavings from adhering again and improve cleanliness.

[0048] In addition, this embodiment uses a linkage design between the translation frame 160 and the turntable 170, so that the brush head 150 can rotate and move simultaneously when brushing the box opening, achieving all-round cleaning of the box opening, which helps to improve the cleaning effect and effectively clean the residual aluminum shavings in the corners of the box opening.

[0049] In some specific embodiments, a plurality of turntables 170 are rotatably arranged on the translation frame 160, and the plurality of turntables 170 are arranged sequentially along the translation direction of the translation frame 160, and a plurality of brush heads 150 are correspondingly provided.

[0050] Understandably, multiple brush heads operating simultaneously at 150mm can cover different positions of the battery box opening at the bottom, effectively improving the efficiency of a single processing cycle. At the same time, it can adapt to the distribution of multiple openings of the same or different specifications, avoiding frequent tooling changes.

[0051] In some specific embodiments, a first motor 190 is also provided on the translation frame 160. The first motor 190 is used to drive the turntable 170 to rotate, thereby using the motor to drive the brush head 150 to rotate to enhance friction and effectively remove the stubborn aluminum shavings.

[0052] Specifically, the translation frame 160 includes an upper plate, a lower plate, and a vertical rod connecting the upper plate and the lower plate. The turntable 170 is mounted on the upper plate, and the first motor 190 is mounted below the upper plate.

[0053] In some specific embodiments, a first slide rail 200 is provided on the outside of the ultrasonic cleaning chamber 100, and a translation frame 160 is slidably mounted on the first slide rail 200. A second motor 210 is also provided outside the ultrasonic cleaning chamber 100, and a first screw 220 is provided at the output end of the second motor 210. The first screw 220 is threadedly connected to the translation frame 160. Thus, the first screw 220 drives the translation frame 160 to move, which can improve the translation accuracy of the translation frame 160 and ensure the consistency of the brushing trajectory. At the same time, the first slide rail 200 guides and reduces vibration interference, extending the service life of the equipment.

[0054] In some specific embodiments, multiple battery boxes are arranged on the conveying mechanism 130 in a direction that is horizontal and perpendicular to the conveying direction of the conveying mechanism 130. The length direction of the first slide rail 200 is horizontal and perpendicular to the conveying direction of the conveying mechanism 130. Thus, the direction of the first slide rail 200 is perpendicular to the conveying direction, enabling multiple battery boxes to be processed in parallel, effectively improving production capacity.

[0055] The unloading mechanism 180 is used to transfer the battery box on the conveying mechanism 130 to the brush head 150 for brushing and then unload the battery box.

[0056] Specifically, the unloading mechanism 180 is configured as a robotic arm, thereby making the unloading and conveying action of the battery box by the unloading mechanism 180 more flexible.
