Description

Technical Field

[0001] The utility model relates to the field of conveyor belts, in particular to a conveyor belt for battery cell production. Background Art

[0002] A conveyor belt is an important conveying device. It is the load-bearing medium of the conveying system and consists of one or more endless belts. These belts are usually made of materials such as rubber, plastic, and metal. They are installed between two or more rollers to form a continuous conveying line. According to different materials and uses, conveyor belts can be divided into various types, such as rubber conveyor belts, plastic conveyor belts, metal conveyor belts, etc. Different types of conveyor belts have different characteristics. For example, rubber conveyor belts are wear-resistant and corrosion-resistant, plastic conveyor belts are lightweight and easy to clean, and metal conveyor belts have high strength and strong load-bearing capacity. In addition, according to different application scenarios, conveyor belts can also be customized with different patterns and thicknesses to meet different conveying requirements and safety requirements. A conveyor belt usually consists of one or more layers of materials. The tensile force is usually provided by industrial polyester cloth, and the coating may be composed of materials such as PVC, PU, PE, SIR, etc. to ensure the stability and mechanical properties of the conveyor belt. The application range of conveyor belts is very wide, covering almost all industries that require material transportation. In industrial production, conveyor belts are used for the transportation of raw materials, semi-finished products and finished products during the production process, and the discharge of waste.

[0003] The working principle of the conveyor belt is based on principles such as power transmission, motion control, and object handling. It mainly consists of a conveyor belt, a driving device, a tensioning device, idlers, a support frame, and a safety protection device, etc. The driving device usually consists of a motor, a reducer, and bearings, and is used to provide power for the conveyor belt. The tensioning device can adjust the tightness of the conveyor belt to ensure its normal operation. The idlers are used to support and guide the conveyor belt, and the support frame plays a role in fixing the conveyor belt. The safety protection device is used to ensure safety during the transportation process.

[0004] During the production and conveying process of the battery cell, the friction between the battery cell and the surface of the conveyor belt or the insulating skin of the production working surface will generate a large amount of static electricity, which will accumulate on the surface of the battery cell and is likely to cause damage to the electrodes of the battery cell. The accumulation of static electricity during the conveying process will cause breakdown during the conveying process or static breakdown when entering the next process, such as packaging inspection. For the existing conveyor belts used in battery cell production, when the position of the battery cell is offset and the side wall contacts the inner wall of the conveyor belt, it will continuously rub against the inner wall of the conveyor belt during the moving process, and friction is likely to generate static electricity.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Next, in conjunction with Figures 1 - 3 a detailed description will be given to a conveyor belt for battery cell production of the present utility model:

[0020] A conveyor belt for battery cell 16 production includes a frame 1 and a plurality of transmission rollers 2. The plurality of transmission rollers 2 are arranged in parallel in the frame 1. A plurality of driving rollers 3 are further arranged in the frame 1. The plurality of driving rollers 3 are arranged in parallel. Three transmission rollers 2 are arranged between adjacent driving rollers 3. A protective layer is provided on the surface of the driving roller 3. The protective layer is made of polyurethane. The transmission roller 2 is made of stainless steel. A wear-resistant layer is provided on the surface of the transmission roller 2. The wear-resistant layer is made of polyimide film. The polyimide film covers the surface of the transmission roller 2 to improve the wear resistance of the driving roller 3 and the transmission roller 2. At the same time, polyurethane and polyimide film can reduce the generation of static electricity. Adjustable support feet are provided at the bottom end of the frame 1, and a spirit level is provided on the side wall of the frame 1 to facilitate the leveling of the frame 1 and prevent the battery cell 16 from running off track during transportation due to the inclination of the frame 1.

[0021] One end of the driving roller 3 extends to the outside of the frame 1, and a pulley 4 is coaxially arranged. Several pulleys 4 are connected to each other through belts 5. One end of the several driving rollers 3 away from the pulley 4 extends out of the outside of the frame 1 and is connected to the driving motor 6. An ion fan 15 is arranged above the frame 1. The ion fan 15 is connected to the frame 1 through a support frame. The air outlet of the ion fan 15 is aligned with any one of the several transmission rollers 2. A cross arm 8 and several electrostatic probes 7 are arranged in the frame 1. The electrostatic probe 7 is fixedly connected to the frame 1 through the cross arm 8. One end of the probe extends between two adjacent transmission rollers 2. A grounding pin 9 that can contact the bottom surface is arranged on the cross arm 8. Limiting cones 14 are arranged at both ends of the transmission roller 2. The inclined surfaces of the limiting cones 14 are arranged opposite to each other. A control box 10 is arranged on the frame 1. The control box 10 is electrically connected to the driving motor 6.

[0022] The cross arm 8 is provided with a light emitting diode 13, and the two ends of the light emitting diode 13 are electrically connected to the ground pin 9 and the electrostatic probe 7 respectively. When the static electricity on the battery cell 16 is led to the electrostatic probe 7, the static electricity passes through the light emitting diode 13, causing the light emitting diode 13 to generate light, thereby reminding the staff that static electricity is generated. When the static electricity diode generates light frequently, it indicates that the equipment may be faulty.

[0023] A conveyor belt for producing battery cells 16 of the present embodiment is provided with an ion blower 15 and an electrostatic probe 7. When the battery cells 16 are transported on the conveying roller 2 and the driving roller 3, the ion blower 15 can generate a large amount of airflow with positive and negative charges. The driving motor 6 drives the driving roller 3 to rotate, thereby driving the battery cells 16 to move. When the battery cells 16 pass through the ion blower 15, the airflow flows over the surface of the battery cells 16, and reacts with the charges on the battery cells 16 to neutralize the charges, thereby achieving the purpose of eliminating static electricity. The electrostatic probe 7 can lead away the static electricity accumulated in the battery cells 16 and release it to the bottom surface through the grounding pin 9 of the cross arm 8. At the same time, the limiting cone 14 can prevent the direction of the battery cells 16 from deviating during transportation, avoid the side wall of the battery cells 16 from rubbing against the frame 1, further avoid the generation of static electricity, and effectively protect the battery cells 16.
