Description

Technical Field

[0001] This utility model relates to the field of solar cell testing technology, and in particular to a component for testing the quality of solar cells. Background Technology

[0002] Solar cell quality testing is a critical step in ensuring module performance and reliability. Common tests include visual inspection, electrical performance testing, mechanical strength testing, and environmental durability testing. Visual inspection identifies cracks and defects; electrical performance testing measures open-circuit voltage, short-circuit current, and conversion efficiency; mechanical strength testing assesses impact and load resistance; and environmental testing verifies resistance to damp heat and UV aging, ensuring that the cells meet industry standards and improving the overall efficiency and lifespan of the photovoltaic system.

[0003] In the electrical performance testing of solar cells, metal probes are typically used to connect the cell electrodes to a circuit testing device to ensure circuit continuity before subsequent testing. However, traditional circuit testing devices use fixed metal probe arrays. This design is prone to damage from prolonged contact and friction after high-frequency testing. Fixed probe arrays are inconvenient to maintain; once damaged, they often require complete replacement, increasing maintenance costs and wasting resources. Furthermore, the fixed structure has poor adaptability and cannot meet the testing requirements of solar cells of different specifications. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional probe arrays, which are fixedly connected to the testing device, are inconvenient to maintain efficiently after wear or damage, requiring complete replacement and increasing maintenance costs.

[0006] As a further improvement of this utility model, a plurality of evenly spaced grooves are provided on the inner wall of the frame, and protrusions that are inserted into the grooves are fixedly provided at the bottom and top of the substrate.

[0007] As a further improvement of this utility model, a vertical guide slider is fixedly connected to one side of the substrate, and a guide groove matching the guide slider is opened on the other side of the substrate.

[0008] As a further improvement of this utility model, a plurality of contact grooves are provided on one side of the circuit connection board, the contact grooves are fitted with the tail end of the contact rod, and a data line is electrically connected to the other side of the circuit connection board.

[0009] As a further improvement of this utility model, side plates are fixedly provided on both sides of the frame, and splicing columns are fixedly provided on the other side of the side plates. Ear plates that are fastened and inserted into the splicing columns are provided on both sides of the circuit connection plate.

[0010] As a further improvement of this utility model, the bottom sides of the cover are fixedly provided with encapsulation protrusions, the top sides of the frame are provided with encapsulation grooves that engage with the encapsulation protrusions, and the bottom side of the cover is provided with recessed holes that engage with multiple protrusions at the top of the substrate.

[0011] The beneficial effects of this utility model are as follows: This utility model sets up multiple detachable and combinable contact test units between the frames.

Through the circuit connection board and data cable, a loop test is performed on the test contact point of the current battery cell to ensure the quality test of the local board surface. In addition, because the base plate of the contact test unit is slidably assembled with each other, and is stably limited with the frame and the cover through multiple protrusions, grooves and recesses, it not only ensures the reliability of the connection, but also facilitates direct replacement or replacement when the local contact rod is damaged, oxidized or has poor contact.

[0020] This utility model provides a component for testing the quality of solar cells, including a frame 1;

[0021] As attached Figure 1 , 3 As shown in Figure 4, the frame 1 is a horizontally placed C-shaped frame. A cover 2 is fastened to the top of the frame 1. Multiple contact test units are fastened between the frame 1 and the cover 2. Each contact test unit includes a substrate 3. Multiple evenly spaced grooves 7 are formed on the inner wall of the frame 1. The bottom and top of the substrate 3 are fixedly provided with protrusions 8 that engage with the grooves 7. Through the protrusions 8 and the grooves 7, the substrate 3 can be vertically inserted and distributed between the frames 1. Encapsulation protrusions are fixedly provided on both sides of the bottom of the cover 2. Encapsulation grooves 13 that engage with the encapsulation protrusions are formed on both sides of the top of the frame 1. The bottom side of the cover 2 is provided with recesses that engage with the multiple protrusions 8 at the top of the substrate 3. Through the recesses, protrusions 8, encapsulation grooves 13 and encapsulation protrusions, the substrate 3 is stably limited between the frame 1 and the cover 2.

[0022] As attached Figure 1-4As shown, multiple contact test units are slidably connected to each other. A vertical guide slider is fixedly connected to one side of the base plate 3 of the contact test unit, and a guide groove 9 matching the guide slider is opened on the other side of the base plate 3; this facilitates the sliding assembly between multiple base plates 3. A connecting cylinder 4 is fixedly installed on one side of the base plate 3. Two connecting cylinders 4 are configured. A spring is fixedly installed on the inner wall of the connecting cylinder 4. The other end of the spring is fixedly connected to a contact rod 5 that is slidably connected to the connecting cylinder 4. One end of the contact rod 5 is used to contact the battery cell for electrical connection to facilitate quality inspection. A circuit connection plate 6 that fits into multiple contact rods 5 is fastened to the other side of the frame 1. Side plates are fixedly installed on both sides of the frame 1. A splicing post 11 is fixedly installed on the other side of the side plate. Ear plates 12 that are fastened to the splicing post 11 are opened on both sides of the circuit connection plate 6; this makes the frame 1 and the circuit connection plate 6 fastened together. The circuit connection board 6 has multiple contact grooves 10 on one side, which fit into the tail end of the contact rod 5. The other side of the circuit connection board 6 is electrically connected to a data line, which can transmit measurement data to a computer control terminal.

[0023] Working principle: In specific implementation, firstly, the substrates 3 of multiple contact test units are sequentially and securely inserted into the grooves 7 of the frame 1 according to the bottom protrusions 8. Then, the encapsulation protrusions on both sides of the bottom of the cover 2 are inserted and fixed into the encapsulation grooves 13 on both sides of the top of the frame 1, while ensuring that the concave holes on the bottom side of the cover 2 are fitted and connected to the protrusions 8 on the top of the substrate 3. The splicing posts 11 and ear plates 12 ensure a secure assembly between the frame 1 and the circuit connection board 6.

[0024] The battery cell to be tested is attached to one side of the frame 1, with one side abutting against multiple contact rods 5. The contact rods 5 are displaced towards the circuit connection plate 6, and the springs are compressed and deformed, inserting the contact rods 5 into the contact grooves 10. The power-on information of the battery cell at this location is transmitted to the computer via the circuit connection plate 6 and connecting wires for quality testing and analysis. When a contact rod 5 is oxidized or has poor contact, the substrate 3 of the contact test unit is moved upward along the guide slides 9 on both sides, separating the damaged contact test unit from the frame 1. After replacing the contact test unit, the power-on test can be performed again.
