Its theoretical photoelectric conversion efficiency is over 25%, and the actual efficiency has reached over 22%. Therefore, a solar cell edge coating passivation device is needed.

[0003] The current solar cell edge coating passivation equipment on the market has the following problems when used:

[0004] 1. When using traditional solar cell edge coating and passivation equipment, workers need to manually fix the solar cells during processing, and then the coating and passivation equipment will coat and passivate the solar cells. The workers will get tired from manually fixing the solar cells for a long time, which will affect the coating and passivation efficiency.

[0005] 2. In most solar cell edge coating and passivation equipment applications, prolonged use of the equipment can lead to a continuous increase in internal heat, affecting the operation of the coating and passivation equipment. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0007] Therefore, one objective of this utility model is to provide a solar cell edge coating passivation device. The device quickly fixes the solar cell using a fixing mechanism, which facilitates the coating and passivation process, reduces the workload of workers, and improves the efficiency of the coating and passivation process. At the same time, the device uses a heat dissipation mechanism to facilitate heat dissipation during use and reduce the internal temperature of the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a solar cell edge coating passivation device, comprising a coating passivation device housing, wherein a fixing mechanism is provided inside the coating passivation device housing, and a heat dissipation mechanism is provided on the outer wall of the coating passivation device housing;

[0009] The fixing mechanism includes a protective shell, a driving component, a spiral rod, a pressure plate, a slide groove, and a cover plate.

The mechanism is connected by the protective shell 201, driving component 202, screw rod 203, pressure plate 204, slide groove 205, and cover plate 206. In the configuration of 6, when fixing the solar cell, the drive component 202 is first activated, which drives the screw rod 203 to rotate. At this time, the rotation of the screw rod 203 causes the pressure plate 204 to move inward, thereby clamping the solar cell inside the coating passivation equipment shell 1. The slide groove 205 limits the pressure plate 204, while the protective shell 201 protects the drive component 202 and the screw rod 203. The cover plate 206 prevents damage to the drive component 202 and the screw rod 203, thereby fixing the solar cell. In this embodiment of the utility model, the drive component 202 is a motor.

An air outlet 307 is formed on the outer wall of the coating and passivation equipment shell 1. A second dustproof net 308 is fixed to the outer wall of the air outlet 307. The heat dissipation is achieved through the connecting plate 301, the heat dissipation vent 302, the first dustproof net 303, and the fan 304. The fan 304, heat dissipation housing 305, air inlet 306, air outlet 307, and second dustproof net 308 are configured so that, during use, when heat dissipation is required inside the coating and passivation equipment housing 1, cold air enters the heat dissipation housing 305 through the air inlet 306, and the fan 304 blows the cold air from the heat dissipation housing 305 into the coating and passivation equipment housing 1 for heat dissipation. Then, the heat dissipation vent 302 on the outer wall of the connecting plate 301 is equipped with a first dustproof net 303, which prevents dust from entering the coating and passivation equipment housing 1 and causing damage to it. The hot air inside the coating and passivation equipment housing 1 is discharged through the air outlet 307, while the second dustproof net 308 prevents dust from entering the coating and passivation equipment housing 1, thereby dissipating heat inside the coating and passivation equipment housing 1.

[0027] Furthermore, the drive components 202 are evenly distributed inside the protective shell 201. The rotation shaft of the drive component 202 passes through the protective shell 201 and is connected to the screw rod 203.

[0028] Furthermore, the pressure plates 204 are evenly distributed on the outer wall of the spiral rod 203, and the slide grooves 205 are evenly opened on the outer wall of the protective shell 201. With the setting of the pressure plates 204, the rotation of the spiral rod 203 causes the pressure plates 204 to move inward, so that the pressure plates 204 clamp the solar cells inside the shell 1 of the coating passivation equipment.

[0029] Furthermore, the slide groove 205 and the pressure plate 204 form a sliding structure, and the pressure plate 204 and the screw rod 203 form a sliding structure.

The hot air inside the coating and passivation equipment housing 1 is discharged through the air outlet 307. The second dustproof net 308 prevents dust from entering the coating and passivation equipment housing 1, thereby dissipating heat inside the coating and passivation equipment housing 1.

[0032] Working principle: During use, when fixing the solar cells, the drive unit 202 is activated, causing the screw rod 203 to rotate. This rotation of the screw rod 203 moves the pressure plate 204 inwards, clamping the solar cells inside the coating and passivation equipment housing 1. The sliding groove 205 limits the pressure plate 204, while the protective shell 201 protects the drive unit 202 and screw rod 203. The cover plate 206 prevents damage to the drive unit 202 and screw rod 203, thus fixing the solar cells. In this embodiment, the drive unit 202 is a motor. When it is necessary to coat... When heat is dissipated inside the passivation equipment housing 1, cold air enters the heat dissipation housing 305 through the air inlet 306. The fan 304 blows the cold air inside the heat dissipation housing 305 towards the inside of the coating and passivation equipment housing 1 for heat dissipation. Then, a first dustproof net 303 is installed on the heat dissipation port 302 on the outer wall of the connecting plate 301.
