Description

Technical Field

[0001] This utility model relates to the field of battery cell testing technology, specifically a testing device for solar cells. Background Technology

[0002] In the solar energy industry, solar cells are a core component, and their performance directly determines the overall efficiency and stability of a solar power generation system. Solar cells are the key element in converting solar energy into electrical energy, achieving this conversion through the photoelectric effect. With the continuous increase in global demand for clean energy, solar energy, as a clean and renewable energy source, has received much attention. To ensure that solar cells can operate efficiently and stably in practical applications, comprehensive and accurate performance testing is crucial. Only through rigorous testing and selection of high-performance cells can the reliability of solar power generation systems be guaranteed, power generation efficiency improved, maintenance costs reduced, and thus the healthy development of the solar energy industry promoted. Traditional solar cell testing technologies suffer from numerous drawbacks. On the one hand, traditional testing equipment has a low degree of automation, relying heavily on manual operation. This not only results in low testing efficiency but also makes it difficult to avoid errors caused by human intervention, significantly reducing the accuracy of test results and failing to provide precise data support for production and application. On the other hand, traditional testing devices have relatively limited functions, often only able to test some performance indicators of the cells, failing to achieve comprehensive testing and evaluation. This makes it difficult to detect potential quality problems in a timely manner, affecting the overall quality and market competitiveness of solar cells. Furthermore, traditional testing technologies are inadequate in waste disposal. Waste generated during the testing process cannot be properly collected and treated, leading to resource waste and potential environmental pollution. All of these factors severely restrict the sustainable development of the solar cell industry. Therefore, we propose a testing device for solar cells. Utility Model Content

Multiple sets of equidistantly linearly distributed electrically controlled adsorption plates 6 are fixedly installed at the bottom of the connecting plate 5. A detector 7 is fixedly installed between adjacent electrically controlled adsorption plates 6 at the bottom of the connecting plate 5. During the operation of the detection structure, the telescopic cylinder 4, in addition to adjusting the detection height according to the thickness of the solar cell, also features rapid response. It adopts advanced pneumatic control technology, and the time from receiving the control command to completing the telescopic action is extremely short, ensuring efficient detection. For example, when detecting different batches of solar cells... The device can quickly adjust its height, reducing waiting time. The electrically controlled adsorption plate 6 is made of special magnetic material, providing stable and adjustable adsorption force. When adsorbing solar cells, it can adjust the adsorption force by controlling the current based on the material and surface characteristics of the solar cells, avoiding damage to the solar cells due to excessive adsorption force or displacement due to insufficient adsorption force. The detector 7 integrates a variety of advanced detection technologies, such as spectral analysis and resistance measurement.

[0018] Furthermore, the transmission structure includes a material inlet 8, a guide plate 9, and rollers 11. A through material inlet 8 is provided on the side of the detection frame 2. A guide plate 9 is fixedly installed on the side of the detection frame 2 corresponding to the bottom edge of the material inlet 8. Multiple sets of equidistant, linearly distributed rollers 11 are rotatably installed between the two sides inside the detection frame 2. A driven wheel 12 is fixedly installed at the end of one end of the base 1. The driven wheels 12 mesh with each other. The material inlet 8 can accommodate various specifications of solar cells, allowing both standard and special-sized cells to pass smoothly. The surface of the guide plate 9 is made of a smooth material, such as polytetrafluoroethylene (PTFE), which effectively reduces friction during cell transmission. To prevent scratches on the surface of the battery cells, the guide plate 9 also has a certain degree of elasticity, which can buffer and correct slight deviations in the battery cells. The roller 11 is made of high-strength, wear-resistant material to ensure stable operation over a long period of time. Its surface has been specially treated to increase the friction between it and the battery cells, making the battery cells move more smoothly during transmission.

The fixing plate 14 not only serves to fix the motor 15. It also has good shock absorption performance. The fixing plate 14 is made of rubber and metal composite material, which can effectively reduce the vibration generated by the motor 15 during operation and transmit it to the detection frame 2, preventing the vibration from affecting the accuracy of the detection results. The tooth profile of the driving wheel 13 and the driven wheel 12 has been optimized and adopts a special involute tooth profile, which can improve the transmission efficiency and reduce noise. During the meshing process, the contact between the tooth surfaces is more uniform, reducing wear and extending service life. At the same time, the driving wheel 13 and the driven wheel 12 are also equipped with sealing protection devices to prevent dust and impurities from entering the meshing parts and affecting the transmission performance.

[0020] Furthermore, the waste collection structure includes a waste outlet 16 and a waste bin 17. The waste outlet 16 is located on the side of the detection frame 2, and the waste bin 17 is slidably installed inside the waste outlet 16. The bottom of the waste bin 17 is slidably connected to the top of the base 1. The opening size of the waste outlet 16 can be adjusted according to the size of the battery cells to ensure that the waste can fall smoothly into the waste bin 17. An automatic sensing device is installed inside the waste outlet 16. When the detection structure determines that the battery cells are waste and sends a signal, the waste outlet 16 can open quickly and simultaneously activate the positioning device of the waste bin 17 to ensure that the waste falls accurately into the waste bin 17. The waste bin 17 adopts a foldable design. When the amount of waste collected is small, it can be folded up to save space. When there is a lot of waste, it can be unfolded to increase the capacity.

Furthermore, the transparent window on the side of the control structure allows operators to directly observe the testing of the battery cells within the testing frame, enabling timely detection of abnormalities such as poor battery cell adhesion or other unusual phenomena during testing. This allows for prompt equipment adjustments or problem-solving. Before testing begins, the operator activates the device using the control panel and buttons. The control panel receives the operating command and transmits the signal to the motor structure. Supported by the fixed plate 14, motor 15 begins to operate. Its output shaft drives the drive wheel 13 to rotate. Since the drive wheel 13 meshes with the driven wheel 12, the driven wheel 12 rotates accordingly, which in turn drives the roller 11 to rotate synchronously. The transmission structure begins to work. The solar cell to be tested is put into the feed port 8 on the side of the detection frame 2. The guide plate 9 guides the cell to fall smoothly onto the roller 11. The rotation of the roller 11 pushes the cell to move within the detection frame 2, achieving smooth and fast transmission and improving the continuity of the test. When the cell is transmitted to the area directly below the detection area, motor 15 stops running, and the cell is accurately positioned. At this time, the detection structure begins to work. After receiving the command from the control structure, the telescopic cylinder 4 at the bottom of the top cover 3... Based on parameters such as the thickness of the solar cells, the telescopic length is precisely adjusted, causing the connecting plate 5 to descend. After the electrically controlled adsorption plates 6, equidistantly distributed linearly at the bottom of the connecting plate 5, contact the solar cells, they generate an adsorption force when energized, firmly adsorbing the solar cells and ensuring their fixed position during testing. This avoids displacement affecting the test results. Detectors 7, fixedly installed between adjacent electrically controlled adsorption plates 6, begin performance testing of the solar cells. The detectors 7 are evenly distributed on the solar cells, enabling comprehensive and detailed testing of the performance of different areas of the solar cells, significantly improving testing accuracy and obtaining more precise test data. During the testing process, the operator can directly observe the testing status of the solar cells within the testing frame 2 through a transparent window next to the control structure. Furthermore, if problems such as poor adhesion of the battery cells or abnormal phenomena are found during the testing process, instructions can be immediately sent to the control structure through the operation buttons to adjust the equipment or handle the problem in a timely manner. The operation screen displays test data, equipment operating status and other information in real time, allowing operators to understand the testing progress at any time. After the test is completed, if the battery cells are determined to be waste, the waste outlet 16 on the side of the test frame 2 opens, and the battery cells slide into the waste bin 17 below through the waste outlet 16. The waste bin 17 is fixedly connected to the top of the base 1 and slides within the waste outlet 16, which facilitates the timely collection of waste generated during the testing process, avoids waste accumulation affecting the normal operation of the testing work, and also facilitates subsequent unified treatment, reducing environmental pollution.
