Description

Technical Field

[0001] This utility model relates to the field of solar cell testing technology, and in particular to a solar cell probe testing device that is easy to calibrate. Background Technology

[0002] A solar panel is a thin film of photovoltaic semiconductors that generates electricity directly using sunlight. It is also known as a "solar chip" or "photovoltaic cell". As long as the illuminance conditions are met, it can instantly output voltage and generate current when there is a circuit.

[0003] The manufacturing process of solar panels involves several key steps, including silicon wafer cleaning, diffusion junction formation, etching, coating, screen printing, and sintering. Each step is crucial, and if problems arise and are not addressed in time, it can lead to a waste of human, material, and financial resources. Therefore, the inspection of solar panels during the production process is of paramount importance.

[0004] Existing solar cell probe testing equipment requires manually loosening the mounting plate with the probe and adjusting its position to align the grid lines when calibrating the grid lines on the solar panel. However, this alignment method suffers from low calibration efficiency. Utility Model Content

[0028] Please see Figures 1 to 4 As shown, this embodiment provides a solar cell probe 32 testing device that is easy to calibrate, which includes a base 10, a lifting assembly 20, a testing assembly 30, and an adjustment assembly 40. A testing platform 50 is provided on the base 10, and the testing platform 50 is configured to place the solar cell to be tested. The adjustment assembly 40 includes a first adjustment member 41 and a second adjustment member 42. The first adjustment member 41 is provided at the driving end of the lifting assembly 20, and the testing assembly 30 is adjustablely mounted on the first adjustment member 41 through the second adjustment member 42. The first adjustment member 41 is configured to coarsely position the testing assembly 30, and the second adjustment member 42 is configured to finely position the testing assembly 30. The lifting assembly 20 is provided on the base 10 and is configured to drive the first adjustment member 41 to reciprocate in the vertical direction to move the testing assembly 30, thereby bringing the testing end of the testing assembly 30 closer to or further away from the grid lines on the solar cell to be tested.

[0029] As can be seen, the first adjusting member 41 achieves coarse positioning of the detection component 30, and the second adjusting member 42 achieves fine positioning. When the grid line deviation distance is not large, there is no need to adjust the position of the first adjusting member 41, which improves the calibration efficiency and accuracy.

[0030] In one embodiment, the lifting assembly 20 includes two driving members 21, a lifting plate 22, and multiple guide columns 23. The multiple guide columns 23 are symmetrically arranged on both sides of the detection platform 50. The lifting plate 22 is located at the moving end of the multiple guide columns 23. The two driving members 21 are symmetrically arranged on both sides of the lifting plate 22. The driving members 21 are configured to drive the lifting plate 22 to reciprocate in the vertical direction. An avoidance groove is provided in the middle position of the lifting plate 22. The avoidance groove is configured to avoid the detection assembly 30.

[0031] Specifically, the driving component 21 is a cylinder.

[0032] As can be seen, by symmetrically setting two drive components 21 and cooperating with multiple guide columns 23, the horizontality and stability of the lifting plate 22 during lifting are ensured, the detection component 30 is prevented from tilting, and the vertical alignment accuracy between the detection end and the grid line is guaranteed.

[0033] In one embodiment, the first adjusting member 41 includes a first slide rail 410, a second slide rail 411, and a plurality of first sliders 412. The first slide rail 410 and the second slide rail 411 are symmetrically arranged on the lifting plate 22 along a first direction and located within a clearance groove. The plurality of first sliders 412 are movably installed within the first slide rail 410 and the second slide rail 411. Each first slider 412 has a screw 413 at its bottom, and the screw 413 is configured to fix or loosen the first slider 412 to adjust the position of the first slider 412 in a second direction. Figure 1 (middle x direction) and second direction ( Figure 1 The y-direction and the y-direction are perpendicular to each other.

[0034] As can be seen, the first slide rail 410 and the second slide rail 411 are arranged in parallel. By adjusting the position of the first slider 412 in the slide rail, the detection component 30 can be coarsely positioned on the horizontal plane to adapt to the differences in grid layout of different specifications of battery cells and improve equipment compatibility.

[0035] In one embodiment, the second adjusting member 42 includes a first guide rail 420, a second guide rail 421, an adjusting rod 422, an adjusting block 423, and a connecting plate 424. The first guide rail 420 is vertically disposed on the first slider 412. The adjusting block 423 is reciprocally disposed on the first guide rail 420 in the vertical direction. The adjusting rod 422 is vertically downward connected to the adjusting block 423 and is configured to adjust the position of the adjusting block 423 in the vertical direction. The second guide rail 421 is disposed in the first slider 412 in a first direction. A second slider is disposed inside the second guide rail 411 and is connected to the connecting plate 424. The second guide rail 411 is configured to guide the connecting plate 424 to move in a second direction. A roller 425 is disposed on the connecting plate 424 and abuts against the adjusting surface of the adjusting block 423. The roller is configured to drive the connecting plate 424 to move in the second direction according to the vertical movement of the adjusting block 423.

[0036] As can be seen, the adjusting rod 422 drives the adjusting block 423 to move in the vertical direction, and its inclined surface pushes the roller 425 to make the connecting plate 424 move in the second direction, converting the vertical displacement into the horizontal displacement for fine adjustment, which is convenient for operation and improves the calibration accuracy.

[0037] In one implementation, the adjustment surface of the adjustment block 423 is set as an inclined surface.

[0038] As can be seen, the inclined surface design of the adjusting block 423 can convert vertical displacement into horizontal displacement, making it easy to achieve precise positioning through small-amplitude adjustments.

[0039] In one embodiment, the detection component 30 includes a plurality of mounting plates 31 and a plurality of probes 32, with one mounting plate 31 corresponding to one connecting plate 424, and the plurality of probes 32 being arranged at equal intervals along the length direction of the mounting plate 31.

[0040] As can be seen, multiple probes 32 are equidistantly arranged, which can simultaneously detect multiple grid lines on the solar cell, thus improving detection efficiency; each mounting plate 31 corresponds to a connecting plate 424, and the position of each group of probes 32 can be independently adjusted to adapt to solar cells with different grid line spacing.

[0041] In one embodiment, the testing platform 50 includes a support platform 51 and a shelf 52. The support platform 51 is located in the middle of the base 10, and the shelf 52 is located on the support platform 51. A receiving groove is provided in the middle of the top of the shelf 52, and the receiving groove is configured to place the battery cell to be tested.

[0042] As can be seen, the receiving slot of the placement plate 52 limits the position of the battery cell, preventing the battery cell from shifting during testing, ensuring that the relative position of the grid line and the detection component 30 is fixed, and improving the stability of the test.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0044] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples.
