Description

Technical Field

[0001] This utility model relates to the field of solar panel processing technology, and in particular to a heat dissipation device for solar panel processing. Background Technology

[0002] The core process in photovoltaic module manufacturing is lamination. This process uses a laminator to bond materials such as glass, encapsulating film (EVA or POE), series-connected solar cells, and backsheet together under vacuum, high temperature, and pressure. During this process, the laminator's heating stage typically heats the laminated materials to a high temperature of 140-150°C to melt, flow, and complete the cross-linking and curing reaction of the encapsulating film, thereby forming a stable and reliable encapsulation structure.

[0003] The cooling process of existing laminators on production lines relies on simple natural cooling or basic air-cooling systems, making it difficult to precisely and programmatically control the heat dissipation rate and temperature. This crude cooling method is prone to problems such as excessively rapid cooling and uneven temperature drop. The thermal stress generated by rapid cooling is the main cause of microcracks inside the solar cells. Therefore, a heat dissipation device for solar panel processing is proposed. Utility Model Content

[0004] To address at least one of the aforementioned technical shortcomings, this utility model provides a heat dissipation device for solar panel processing, comprising: a heat dissipation box, sprockets, a linkage shaft, a synchronous motor, a chain, receiving blocks, and a conveyor belt. The heat dissipation box is vertically arranged, with its top and bottom ends extending through it. Sprockets are provided at each of the eight corners of the heat dissipation box, and a linkage shaft is provided between two sprockets on the same side. The linkage shaft is fixedly connected to the outer wall of the heat dissipation box via a rotating seat. A chain is provided between two sprockets in the same vertical position, and receiving blocks are uniformly fixedly connected to the chain. A synchronous motor for driving the chains on both sides to rotate synchronously is fixedly connected to the outer wall of the heat dissipation box.

[0005] Furthermore, the top of the heat sink is equipped with a robotic arm for gripping the solar panels.

[0006] Furthermore, a conveyor belt is fixedly connected to the bottom of the heat sink.

[0007] Furthermore, a temperature sensor is installed at the bottom outlet of the heat sink.

[0008] Furthermore, the receiving block is made of ceramic fiber insulation material and has anti-slip rubber pads on its surface to avoid scratching the solar panel and reduce heat conduction.

[0009] Furthermore, the receiving blocks are arranged in the chain in a way that forms a multi-layered, parallel conveying path within the heat dissipation box.

[0010] Furthermore, the synchronous motor is a synchronous stepper motor. Beneficial effects

[0011] When dissipating heat from the solar panel, the solar panel is placed on the receiving block on the same layer. Driven by a synchronous motor, the chains on both sides rotate synchronously, causing the receiving block with the solar panel to move slowly downwards. There are four chains in total, located vertically at the four corners of the heat dissipation box. The two chains on the same side are driven synchronously through a linkage shaft. As the solar panel moves slowly downwards, it dissipates heat naturally, and the temperature gradually decreases. At the same time, the interior of the heat dissipation box forms a heat dissipation channel with a gradually decreasing temperature from top to bottom, allowing the solar panel to dissipate heat slowly and preventing the formation of micro-cracks.

[0012] During heat dissipation temperature monitoring, a temperature sensor located at the bottom outlet of the heat dissipation box monitors the temperature of the solar panels about to leave the box in real time. When the solar panel temperature drops below the set threshold required by the process, the system determines that heat dissipation is complete and the process proceeds normally. If the temperature of a solar panel is abnormally high, the system can issue an alarm or automatically reduce the chain speed to extend the heat dissipation time of that panel inside the box, ensuring that every solar panel leaving the factory meets the qualified cooling standards, thus playing a strict quality control role.

[0013] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

[0017] Please refer to Figures 1 to 2 ; This embodiment provides a heat dissipation device for solar panel processing, including: a heat dissipation box 1, sprockets 2, a linkage shaft 3, a synchronous motor 4, a chain 5, a receiving block 6, and a conveyor belt 7. The heat dissipation box 1 is vertically arranged, with its top and bottom ends connected through each other. Each of the eight corners of the heat dissipation box 1 is provided with a sprocket 2. A linkage shaft 3 is provided between two sprockets 2 located on the same side. The linkage shaft 3 is fixedly connected to the outer wall of the heat dissipation box 1 through a rotating seat. A chain 5 is provided between two sprockets 2 located in the same vertical position. A receiving block 6 is evenly fixedly connected to the chain 5. A synchronous motor 4 for driving the chains 5 on both sides to rotate synchronously is fixedly connected to the outer wall of the heat dissipation box 1.

[0018] In practical implementation, when dissipating heat from the solar panel, the solar panel is placed on the receiving block 6 on the same layer. The synchronous motor 4 drives the chains 5 on both sides to rotate synchronously, causing the receiving block 6 on which the solar panel is placed to move slowly downwards. There are four chains 5 in total, located vertically at the four corners of the heat dissipation box 1. The two chains 5 on the same side are driven synchronously through the linkage shaft 3. As the solar panel moves slowly downwards, it dissipates heat naturally, and the temperature decreases slowly. At the same time, the interior of the heat dissipation box 1 forms a heat dissipation channel with the temperature gradually decreasing from top to bottom, allowing the solar panel to dissipate heat slowly and avoiding the formation of micro-cracks.

[0019] The heat sink 1 is very long, creating sufficient channels for heat dissipation.

[0020] Furthermore, the top of the heat sink 1 is equipped with a robotic arm for gripping the solar panels.

[0021] In practice, during the loading process, the equipment at the front end of the production line transfers the pre-processed, high-temperature solar panels to the feeding station at the top of the heat sink 1. At this point, a robotic arm located at the top of the heat sink 1 activates, its actuator precisely gripping the edge of the solar panel and placing it stably on two receiving blocks 6 at the same horizontal level. This automated loading by the robotic arm achieves continuous and precise feeding operations, effectively avoiding panel damage or inefficiency that could occur with manual operation, and ensuring the automation and safety of the production process.

[0022] Furthermore, a conveyor belt 7 is fixedly connected to the bottom of the heat sink 1.

[0023] In practical implementation, during material unloading, when the receiving block 6 carrying the solar panel moves with the chain 5 to the bottom of the heat dissipation box 1, the solar panel, which has completed heat dissipation and cooling, is released by the receiving block 6 and naturally placed on the conveyor belt 7 located below it. The conveyor belt 7 then starts, smoothly transporting the cooled solar panel to the next processing step or collection area. This design achieves seamless integration of heat dissipation and transportation, forming a complete production line and improving overall operational efficiency.

[0024] Furthermore, a temperature sensor is installed at the bottom outlet of the heat sink 1.

[0025] In practical implementation, during heat dissipation temperature monitoring, a temperature sensor installed at the bottom outlet of the heat dissipation box 1 monitors the temperature of the solar panels about to leave the heat dissipation box in real time. When the temperature of the solar panel is detected to have dropped below the set threshold required by the process, the system determines that heat dissipation is complete and the process proceeds normally. If the temperature of a solar panel is abnormally high, the system can issue an alarm or automatically reduce the running speed of chain 5 to extend the heat dissipation time of that panel in the box, ensuring that each solar panel leaving the factory meets the qualified cooling standards, thus playing a strict quality control role.

[0026] Furthermore, the receiving block 6 is made of ceramic fiber insulation material and has anti-slip rubber pads on its surface to avoid scratching the solar panel and reduce heat conduction.

[0027] In practical implementation, the receiving block 6 is made of heat-insulating materials such as ceramic fiber. This design can effectively block the heat from the solar panel from being transferred to the chain 5 and sprocket 2 and other transmission components, avoiding micro-cracks caused by excessive local heat dissipation.

[0028] Furthermore, the receiving block 6 is arranged in the chain 5 in such a way that it forms a multi-layered conveying path that is parallel to each other in the heat dissipation box 1.

[0029] In practice, the cooperation between chain 5 and sprocket 2 creates a multi-layered, circulating conveyor path for the receiving block 6 within the heat dissipation box 1. After the solar panel is carried down the upper half of the box to complete its heat dissipation, the empty receiving block 6 returns to the top in the lower half of the box, forming a continuous closed loop. This compact layout significantly increases the effective heat dissipation path length within the limited equipment height, ensuring that the solar panel has sufficient time to cool slowly, while also significantly improving the space utilization efficiency of the equipment.

[0030] Furthermore, synchronous motor 4 is a synchronous stepper motor.

[0031] In practical implementation, a synchronous stepper motor is used as the power source, possessing precise speed and position control characteristics. By precisely programming the synchronous stepper motor through the control system, the moving speed and start-stop interval of the chain 5 can be accurately controlled, thereby achieving precise adjustment of the falling speed of the solar panels within the heat dissipation box 1. This ensures that solar panels of different specifications or with different initial temperatures can obtain the most suitable heat dissipation time, optimizing the adaptability and controllability of the heat dissipation process.
