[0002] Photovoltaic silicon wafers are the core and most valuable component of a solar power system. Their function is to convert solar energy into electrical energy, which is then stored in batteries or used directly as a power source. In BC cells (back-contact cells, which can be combined with various circuits), after the silicon wafers are stringed together, they need to undergo power-on testing and visual inspection to determine if they meet requirements. Manual inspection is inefficient, as conventional visual inspection cannot observe the sides of the cell strings, affecting batch quality. Utility Model Content

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 6 As shown, in this embodiment, a battery string power-on testing machine includes a power-on input track 1, a detection horizontal module 2, a good product output rack 3, and a defective product output rack 4. The power-on input track 1 is located below the middle of the detection horizontal module 2. The driving end of the detection horizontal module 2 is connected to a detection flipping component 5. Power-on clamps 6 are installed on both sides of the detection flipping component 5. A power-on detection camera 7 is arranged below one side of the power-on input track 1. Two sets of good product storage frames 8 move laterally on the good product output rack 3. A first paper separator frame 9 is fixed on the good product output rack 3. A defective slide rail 10 is arranged below the defective slide rail 4. A second paper separator frame 11 slides on the defective slide rail 10. The second paper separator frame 11 is located above the defective product output rack 4.

[0023] The power input rail 1 connects to the front string welding structure to receive the string of batteries that have been wired together. After the power clamp 6 clamps a set of battery strings, it is flipped 90 degrees by the detection flipping component 5. Under the action of the power detection camera 7, the battery strings are photographed and formed. Qualified good products are moved into the good product storage box 8. For each row of battery strings, a paper divider is taken out from the first paper divider box 9 and placed on the good battery strings so that the upper and lower battery strings will not directly contact and be damaged. If it is a defective product, it will be placed on the defective output rack 4. The defective slide rail 10 moves the second paper divider box 11 and places the paper divider in the second paper divider box 11 between the upper and lower battery strings.

[0024] The power input track 1 has several input adsorption holes 12 distributed on it. An input air pipe 13 is installed on the side of the power input track 1. The input air pipe 13 is connected to the input adsorption holes 12. Under the control of the input air pipe 13, the negative pressure of the input adsorption holes 12 adsorbs and transports the battery string.

[0025] The detection longitudinal module 14 is connected to the drive end of the detection transverse module 2. The detection flipping assembly 5 includes a detection flipping motor 15, which is located on the drive end of the detection longitudinal module 14. A flipping shaft 16 is connected to the drive end of the detection longitudinal module 14 via a bearing. Both the drive end of the detection flipping motor 15 and one end of the flipping shaft 16 are connected to detection flipping pulleys 17. A detection flipping belt 18 is connected between the pulleys. Detection clamping cylinders 19 are installed at both ends of the flipping shaft 16. An energized clamp 6 is located on the drive end of the detection clamping cylinder 19.

[0026] During testing, the longitudinal detection module 14 controls the power-on clamp 6 to move down onto the power-on input track 1. Under the action of the detection clamping cylinder 19, the front and rear power-on clamps 6 clamp the battery string. After the longitudinal detection module 14 raises the battery string, the detection flipping motor 15 controls the flipping shaft 16 to rotate 90° through the detection flipping pulley 17 and the detection flipping belt 18. The power-on clamp 6 drives the battery string to flip 90 degrees, so that the side of the battery string faces down. The transverse detection module 2 brings the battery string above the power-on detection camera 7 for visual inspection.

[0027] A first lifting module 20 is provided on one side of the detection horizontal module 2. Several first paper-separating suction nozzles 21 are distributed on the drive end of the first lifting module 20. A second lifting module 22 is provided on the other side of the detection horizontal module 2. Several second paper-separating suction nozzles 23 are distributed on the drive end of the second lifting module 22. A horizontal cylinder 24 is provided on both sides of the good product output rack 3. A side stop block 25 is connected to the horizontal cylinder 24. The good product storage frame 8 is located inside the side stop block 25. A storage frame lifting electric cylinder 26 and a guide sleeve 27 are provided below the good product storage frame 8. A lifting square tube 28 is connected to the drive end of the storage frame lifting electric cylinder 26. A lifting guide rod 29 is connected to the bottom of the lifting square tube 28. The lifting guide sleeve 27 slides in the guide sleeve 27. The lifting square tube 28 lifts the good product storage frame 8.

[0028] Qualified battery strings are carried to the good product conveyor by the inspection horizontal module 2. The storage frame lifting cylinder 26 controls the lifting square tube 28 to rise along the lifting guide rods 29 on both sides, lifting the lower good product storage frame 8 to facilitate the reception of battery strings. The first lifting module 20 controls the first paper separator suction nozzle 21 to move down into the first paper separator frame 9 to absorb a paper separator and place it on the battery string of the good product storage frame 8, so that the battery string and the paper separator are placed alternately. When the current good product storage frame 8 is full, the storage frame lifting cylinder 26 controls the good product storage frame 8 to return to the side block 25. The horizontal cylinder 24 moves the full good product storage frame 8 outward to facilitate external reception. At the same time, the empty good product storage frame 8 enters to continuously receive battery strings.

[0029] The defective battery string is moved to the defective output rack 4. The defective slide rail 10 controls the second paper separator frame 11 to move to the second lifting module 22. The second lifting module 22 drives the second paper separator suction nozzle 23 to absorb the paper separator and place it on the battery string of the defective output rack 4. Similarly, the battery string and the paper separator are placed alternately to complete the power-on detection of the battery string.

[0030] All modules involved in this application are linear modules.
