Description

Technical Field

[0001] The utility model belongs to the field of solar cell processing, and more specifically, relates to a battery string grasping and deviation correction mechanism. Background Art

[0002] A crystalline solar panel is a device that converts solar energy into electrical energy using the photovoltaic effect. Crystalline solar panels, also known as photovoltaic solar panels, are usually composed of multiple photovoltaic cells that absorb sunlight and convert it into direct current electrical energy. These panels can be installed on the roofs, grounds or other suitable areas of buildings for power generation or power supply. As an important means of clean energy power generation, photovoltaic solar panels are receiving increasing attention and widespread application. Globally, governments and enterprises are investing in photovoltaic power generation projects to reduce dependence on traditional fossil fuels, reduce environmental pollution and promote sustainable development.

[0003] During the processing of crystalline solar cells, it is usually necessary to align the bus bar and the battery string before welding. In the process of automated production, this usually involves the transfer of the battery string between processes, that is, in the process of aligning and welding the bus bar and the battery string in the previous process, it is usually necessary to grasp and transfer the battery string. The prior art usually uses a manipulator to drive a suction cup to adsorb and transfer the battery string. During the transfer process, since the position of the battery string will change, it is usually necessary to correct the position, that is, the transfer and deviation correction need to be completed in two processes, which prolongs the processing time and affects the work efficiency; in addition, the existing manipulator suction cups have poor versatility, and it is necessary to stop the machine to replace the suction cup template when transferring battery strings of different specifications, which is inconvenient to use. In view of this, the utility model provides a battery string grasping and deviation correction mechanism. Summary of the Utility Model

[0012] Beneficial effects:

[0013] In the present utility model, the left side, the middle part and the right side of the battery string group on both sides adsorbed by the suction cup module are simultaneously photographed and compared by the CCD camera and then fed back. Then, the position of the battery string group is corrected by the XYZU four-axis displacement module, and at the same time of correction, displacement transfer is carried out by the XYZU four-axis displacement module.

[0022] Example:

[0023] Please refer to Figures 1 to 3, the utility model provides a battery string grasping and rectifying mechanism, which includes a CCD camera 1 for photographing and comparison, an XYZU four-axis displacement module 2 for displacement and rectification, and a suction cup module 3 for grasping the battery string. The CCD camera 1 is arranged at the front end of the XYZU four-axis displacement module 2, and the suction cup module 3 is arranged on the XYZU four-axis displacement module 2.

[0024] During operation, the battery string transported by the previous process is grasped on the transfer platform through the suction cup module 3. Then, after photographing and comparison by the CCD camera 1, it is fed back to the PLC, and the PLC issues an instruction to control the XYZU four-axis displacement module 2 to rectify the position of the battery string. While rectifying, the battery string can be transferred to the lower end of the battery string layout module through the XYZU four-axis displacement module 2, preparing for the alignment and welding process of the battery string and the bus bar.

[0025] In this embodiment, please refer to the appendix Figure 1 , three groups of the CCD cameras 1 are provided. The three groups of CCD cameras 1 are arranged in parallel at the front end of the XYZU four-axis displacement module 2. The three groups of the CCD cameras 1 include a left front CCD camera 11, a middle CCD camera 12, and a right front CCD camera 13. As shown by the arrow in the appendix Figure 1 , the left side of the battery string is photographed and compared through the left front CCD camera 11, the middle part of two groups of battery strings is photographed and compared through the middle CCD camera 12, and the right side of the battery string is photographed and compared through the right front CCD camera 13. The three groups of CCD cameras 1 work simultaneously, which can ensure accurate rectification of the battery string during the rectification process.

[0026] After photographing and comparing the left side, middle part, and right side of the battery string groups adsorbed by the suction cup module 3 through the CCD camera 1 and feeding back, the position of the battery string groups is rectified through the XYZU four-axis displacement module 2, and displacement transfer is carried out through the XYZU four-axis displacement module 2 while rectifying. In this way, it can be realized that the position rectification is carried out while the battery string is grasped and transferred between two processes, and the position can be corrected during the grasping and transfer process of the battery string, reducing the processes.

[0027] In this embodiment, please follow the appendix Figure 3The suction cup module 3 includes a suction cup bracket 31, a fixed suction cup 32 and an adjustable suction cup 33.

The fixed suction cup 32 is fixed to the middle part of the bottom surface of the suction cup bracket 31. The adjustable suction cup 33 is slidably connected with the slide groove 34 and is locked and fixed by screws 35. When the battery string is changed, the screws 35 can be loosened to adjust the adjustable suction cup 33 in the slide groove 34, and then locked by screws 35. In this way, the adjustable suction cups 33 on both sides of the suction cup bracket 31 can be slidably adjusted to adapt to battery strings of different sizes, which is convenient for rapid adjustment of the size of the battery string when changing the type, and has the advantage of being integrated and multifunctional.

The Y-axis displacement module 22 is arranged on the X-axis displacement module 21, the Z-axis displacement module 23 is arranged on the Y-axis displacement module 22, and the U-axis displacement module 24 is arranged on the Z-axis displacement module 23. The XYZU four-axis displacement adjustment can be realized by the X-axis displacement module 21, the Y-axis displacement module 22, the Z-axis displacement module 23 and the U-axis displacement module 24, and the position of the battery string can be corrected in cooperation with the suction cup module 3.

[0029] In this embodiment, the Y-axis displacement module 22 includes a Y-axis motor 221, a screw rod 222, a slide rail 223 and a slider 224. The Y-axis motor 221 is transmission-connected to the screw rod 222, the slider 224 is slidingly connected to the slide rail 223 and is threadedly connected to the screw rod 222, and the Z-axis displacement module 23 is arranged on the slider 224. The Y-axis motor 221 can drive the screw rod 222 to rotate, thereby driving the slider 224 to move back and forth in the Y direction along the slide rail 223.
