[0002] Shingle cells are a special solar cell technology that stacks multiple structural units of photovoltaic cells together to form a design similar to tile stacking. In traditional photovoltaic cells, light can only pass through the surface layer to reach the cell chip, and the rest of the light will be reflected. In shingled cells, due to the multi-layer structure, light can be absorbed and converted into electrical energy at all levels, thereby improving the conversion efficiency of the cell. After production, shingled cells need to be tested using testing instruments to test their performance. During the test process, the probe row on the testing instrument is in direct contact with the shingled cell.

[0022] Reference Figures 1-4 As shown, a probe row assembly for measuring shingled battery cells includes two probe racks 1, a slide groove 2 is provided through the upper end of the probe rack 1, and a fixed groove 3 is provided at the front and rear sides of the upper end of the probe rack 1 near the slide groove 2. The interior of the slide groove 2 is slidably connected with a number of evenly distributed fixed blocks 4, and the front and rear ends of the fixed block 4 are fixedly connected with two symmetrically distributed guide blocks 5, and the lower end of the guide block 5 is slidably connected to the inner bottom end of the fixed groove 3. A detection probe 6 is provided on the inner side of the fixed block 4, and a conductive terminal 12 is provided at the front end of the fixed block 4, and the conductive terminal 12 is electrically connected to the detection probe 6. A bus bar 11 is provided at the corresponding position of the front inner wall of the slide groove 2 and the conductive terminal 12, and a wiring port 13 is provided on the front side of the probe rack 1, and the wiring port 13 is electrically connected to the bus bar 11.

[0023] Furthermore, the position of each detection probe 6 can be adjusted by sliding the fixed block 4 along the slide groove 2. At the same time, by inserting or withdrawing the fixed block 4 along the slide groove 2, the number of detection probes 6 can be adjusted, which can flexibly adapt to battery cells of different sizes and meet diverse testing needs.

[0024] Furthermore, the wiring port 13 is connected to the measuring equipment through a connecting wire. During the test, each conductive terminal 12 is in contact with the bus bar 11. The conductive terminal 12 is used to collect the current on the detection probe 6 to the bus bar 11. The bus bar 11 will integrate the current of multiple conductive terminals 12 and transmit it to the measuring equipment through the wiring port 13 and the connecting wire. The performance of the battery cell can be analyzed through the measuring equipment.

[0025] Furthermore, the upper end of the probe frame 1 is fixedly connected to two symmetrically distributed adjusting screws 7, the outer surface of the adjusting screw 7 is threadedly connected to an adjusting sleeve 8, the lower end of the adjusting sleeve 8 is rotatably connected to a movable plate 9, and the lower end of the movable plate 9 is fixedly connected to two symmetrically distributed fixed plates 10, and the lower end of the fixed plate 10 abuts against the upper end of the guide block 5.

[0026] Furthermore, a through groove having the same size as the slide groove 2 is formed through the upper end of the movable plate 9 .

[0027] Furthermore, after the detection probe 6 is moved to a suitable position, the fixing plate 10 is pushed downward by rotating the adjusting sleeve 8 to abut against the guide block 5, so as to limit and fix the guide block 5 to prevent it from moving during the test and affecting the accuracy of the measurement.

[0028] Furthermore, the busbar 11 and the conductive terminal 12 are both made of silver-plated material, which can maintain good conductivity while having low cost.

[0029] Furthermore, two groups of symmetrically distributed mounting holes 14 are provided on the front side of the probe holder 1, with each group of mounting holes 14 having two holes. The probe holder 1 can be installed on the shingled cell test device by aligning the mounting holes 14 with the reserved holes on the shingled cell test device and fixing them with screws.

[0030] Furthermore, the probe holder 1 , the fixing block 4 and the guide block 5 are all made of insulating materials, which can prevent current leakage, reduce the risk of electric shock, and ensure the safety of operators.

[0031] Working principle: When in use, the probe holder 1 is fixed to the shingled cell test equipment through the mounting hole 14 and the screw part to ensure its stability and insert the connecting wire on the test equipment into the wiring port 13. Then, according to the size of the shingled cell to be tested, a certain number of fixing blocks 4 are inserted into the slide groove 2, and the fixed block 4 is slid along the slide groove 2 to adjust the position of the detection probe 6. After adjusting the detection probe 6 to the appropriate position, the adjusting sleeve 8 is rotated to push the movable plate 9 downward so that the fixing plate 10 abuts against the guide block 5, thereby fixing the guide block 5 to prevent the position of the detection probe 6 from changing during the test. Then, the shingled cell to be tested is placed on the test equipment, and the upper and lower sets of detection probes 6 are driven by the test equipment to contact the positive and negative poles of the shingled cell. After power is turned on, the current on the detection probe 6 is collected to the bus bar 11 through the conductive terminal 12. The bus bar 11 integrates the currents of multiple conductive terminals 12 and transmits them to the measuring equipment through the wiring port 13 and the connecting wire. After receiving the current signal from the bus bar 11, the measuring equipment will analyze the performance of the shingled cell according to the current signal and generate test results.
