Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a laser-isolated passivation multi-camera compatible vision device for crystalline silicon solar cells. Background Technology

[0002] Most existing laser processing devices for crystalline silicon cells use dual cameras to calculate angles from two points in the X direction, failing to detect offsets in the Y direction. Furthermore, they suffer from blind spots; the two cameras are typically positioned one in front of the other, with the rear camera's field of view potentially very close to the material edge. Material vibrations can easily cause feature points to move out of the field of view, leading to image capture failure. Calibration and synchronization of the two cameras require precise spatial relationship calibration, and the timing synchronization of image capture is critical. In summary, the existing vision devices in laser processing devices for crystalline silicon cells have the following shortcomings:

[0003] 1. The detection components cannot be adjusted in multiple directions, limiting the positioning and detection of crystalline silicon cells;

Similarly, the top of the adjusting frame 11 is provided with a vertically extending and curved second slot 15. The bottom of the adjusting plate 12 is detachably connected to the second slot 15 via a second connector 16, thereby adjusting the vertical height of the adjusting plate 12. The bottom center of the adjusting plate 12 can be pivotally or hinged to the top center of the adjusting frame 11 via a movable part, allowing the adjusting plate 12 to swing left and right. Finally, the tilt position is fixed by the second connector 16. Both the first connector 14 and the second connector 16 can be detachable connectors such as bolts. The guide plate 19 guides the backlight plate 18 to be fitted onto the adjustment plate 12. The clamping plate 20 can be T-shaped or stepped. The clamping plate 20 is detachably connected to the guide plate 19. The clamping plate 20 can press the backlight plate 18 or adjust the position of the backlight plate 18 to facilitate its positioning. In this embodiment, the output ends of the four camera units 3 are arranged downwards, opposite to the backlight plate 18. The backlight plate 18 supplements the light source, ensuring accurate detection and positioning of the camera units 3 and avoiding detection and positioning deviations. The backlight plate 18 can be adjusted according to the position structure of the positioning component. The backlight plate 18 can provide light sources at different angles to the camera units 3, providing richer and more accurate visual information. It can control the positional accuracy of laser processing to the micrometer level (e.g., within ±10μm), significantly improving process consistency and cell efficiency. The four camera units 3 system can be integrated with technologies such as 3D vision (e.g., 3D line laser camera), thermal imaging, and multispectral imaging to provide multi-dimensional information such as depth, temperature, and material in addition to appearance images, for more complex process monitoring and quality judgment.

The turntable 21 drives the swing arm 22 to rotate, and the crystalline silicon battery can be placed on the placement tray 23. The placement tray 23 is provided with multiple through slots 24, and the light source of the backlight panel 18 can pass through the multiple through slots 24 to avoid the placement tray 23 blocking the light. The placement tray 23 rotates with the rotation of the swing arm 22. The placement tray 23 is located between the vision component and the positioning component in vertical height. When the swing arm 22 rotates, the placement trays 23 corresponding to different swing arms 22 pass through the area between the vision component and the positioning component in sequence, and the batteries on the multiple placement trays 23 are detected or positioned in sequence. Further, the laser isolation passivation device or the laser processing device can be set on one side of the vision component, and can be set in a clockwise direction or a counterclockwise direction along the swing arm 22 to facilitate laser isolation passivation or processing of the detected and positioned batteries. In this embodiment, four swing arms 22 are provided. When the turntable 21 drives the swing arms 22 to rotate 90 degrees, the next tray 23 will rotate to the processing position of the previous tray 23.
