[0002] Composite current collector coating equipment is specifically designed to apply a metal film layer to composite current collector materials. These layers are typically used to improve the current collector's conductivity and mechanical strength. Composite current collectors, composed of polymer materials and metal layers, are widely used in fields such as lithium-ion batteries. Coating technology is crucial to improving the performance of composite current collectors.

[0003] Composite current collector is a new type of lithium battery current collector material. It is composed of a composite of polymer materials and metals. It has the advantages of improving battery safety and enhancing battery performance. However, when it is coated, the coating often fails due to stains adhering to its surface, thus affecting the processing yield. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a coating device for a composite current collector.

[0005] The utility model is implemented by the following technical solutions: a coating device for a composite current collector, comprising a cleaning mechanism for cleaning a material; an adjustment mechanism for adjusting the position of the material during rewinding; a main body mechanism for mounting and fixing the cleaning mechanism and the adjustment mechanism; the cleaning mechanism is located on the upper surface of the main body mechanism, and the adjustment mechanism is located on the upper surface of the main body mechanism;

[0006] The cleaning mechanism comprises a cleaning box, the inner wall of the cleaning box is fixedly connected with a water spray pipe, the inner wall of the cleaning box is rotatably connected with a transmission roller, and the inner wall of the cleaning box is fixedly connected with an ultrasonic vibration sheet.

[0007] Through the above technical solution, the cleaning box is fixedly connected to the water spray pipe. When the film body enters the cleaning box, cleaning liquid is sprayed through the water spray pipe to rinse the outer wall of the film body, thereby washing away the stains on the surface of the film body. The cleaning box is fixedly connected to an ultrasonic vibration plate. After the film body is rinsed by the water spray pipe, high-frequency vibration is emitted through the ultrasonic vibration plate, which can deeply clean the film body, thereby maintaining good cleanliness during subsequent processing, preventing the coating effect from being affected by stains on the outer wall of the film body.

[0008] As a further improvement of the above solution, the lower surface of the cleaning box is fixedly connected to the main body shell, the upper surface of the main body shell is fixedly connected to the air drying box, and the inner wall of the air drying box is fixedly connected to a fan.

[0009] Through the above technical solution, the air drying box is fixedly connected to the fan. When the film body is cleaned, it will move backward through the transmission roller. When the film body enters the air drying box, the high-speed rotation of the fan inside it can quickly dry the water stains on the surface of the film body, so that the surface of the film body has good dryness and neatness during coating, thereby increasing the success rate of the overall coating of the equipment.

[0011] Through the above technical solution, the fixed bracket is rotatably connected to the film body, and the film body is fixedly connected to the power motor. Two power motors are set to control the retraction and extension of the film body. When the first power motor controls the film body to release, the film body enters the equipment for processing. A second power motor and a fixed bracket are set at the end of the equipment to control the film body to be rolled up, thereby increasing the degree of automation of the overall equipment.

[0012] As a further improvement of the above solution, the adjustment mechanism includes an adjustment steel roller, the outer wall of the adjustment steel roller is rotatably connected to an L bracket, the lower surface of the L bracket is fixedly connected to a slider, and the inner wall of the slider is slidably connected to a slide rod.

[0013] Through the above technical solution, the adjustment steel roller is fixedly rotatably connected to the L bracket, and the L bracket is fixedly connected to the slider. When the film body passes through the surface of the adjustment steel roller, the two sliders slide against each other to control the adjustment steel roller for fine-tuning, and adjust its position in real time when the film body is rolled up, thereby preventing the film body from being misaligned when being rolled up, affecting subsequent processing and use, and setting the slider to slide and connect the slide rod. By setting the slider to slide on the outer surface of the slide rod, it can provide guidance for the slider when sliding, thereby preventing the slider from deviating when sliding.

[0015] Through the above technical solution, the cylinder is fixedly connected to the fixed base, and the fixed base is fixedly connected to the cylinder, so that the stability of the mechanical equipment can be increased. The cylinder is fixedly connected to the pneumatic connecting rod, and the pneumatic connecting rod is fixedly connected to the slider. The pneumatic connecting rod is controlled by the cylinder to extend and retract and drive the slider to slide, so that the position of the steel roller can be directly adjusted by controlling the cylinder, thereby increasing the automation of the mechanical equipment and achieving the effect of reducing manpower.

[0017] Through the above technical solution, the main body shell is fixedly connected to the base, and the stability of the entire mechanical equipment can be increased by fixing the base on the lower surface of the main body shell.

[0018] As a further improvement of the above solution, a coating box is fixedly connected to the upper surface of the main body shell, and a supporting steel roller is fixedly connected to the upper surface of the main body shell.

[0019] Through the above technical solution, the main shell is fixedly connected to the coating box and the supporting steel roller. By arranging the supporting steel roller on the upper surface of the main shell, the supporting steel roller can provide supporting force to the film body, thereby increasing the smoothness of the overall equipment operation.

[0020] Compared with the prior art, the beneficial effects of the present invention are:
