When loading the panels, the panels to be cut are placed into the feed chute 301 and positioned using the clamping plates 32. The feed head 34 then completes the loading process. The feed frame 31 is equipped with two symmetrically arranged CCD lenses 36, corresponding to the output end of the feed chute 301. These CCD lenses 36 are used to detect the location of the cell cut at the output end of the feed chute 301, ensuring accurate placement of the panels and cutting precision.

[0048] The clamping device 40 is arranged on the feeding device 30 and is located directly above the output end of the feeding device 30. The clamping device 40 is connected to the control cabinet 20. In this embodiment, the clamping device 40 includes a pressing frame 41, a pressing plate 42 and a first pressing drive mechanism 43.

One preheating device 50 is mounted on the feeder 30 and located below the output end of the feeder 30, while the other preheating device 50 is mounted on the pressing device 40 and located above the output end of the feeder 30. The two preheating devices 50 allow for simultaneous preheating of both the top and bottom sides of the panels, resulting in a more effective preheating effect.

[0050] The cutting device 60 is provided in two configurations, one on the left and the other on the right side of the feeder 30. The movable ends of the two cutting devices 60 are respectively movable on the upper and lower sides of the output end of the feeder 30. The cutting device 60 is connected to the control cabinet 20. The two cutting devices 60 can sequentially cut from the upper and lower sides of the solar panel, ensuring the cutting effect and avoiding adhesion. In this embodiment, each cutting device 60 includes a mounting base 61, a robotic arm 62, a cutter 63, and a detection head 64. The mounting base 61 is provided on the side of the feeder 30.

The cutter 63 is provided on the output end of the robotic arm 62 and moves back and forth with the robotic arm 62. The detection head 64 is provided on the output end of the robotic arm 62 and is located on the side of the cutter 63. The detection head 64 is used not only to detect the cutting position of the cutter 63 but also to monitor the cutting process in real time.

[0051] The receiving device 70 is arranged on the frame 10 and is located beside the output end of the feeding device 30. The receiving device 70 is connected to the control cabinet 20. In this embodiment, the receiving device 70 includes a receiving frame 71, a movable seat 72, a first receiving drive mechanism 73, a movable plate 74, a second receiving drive mechanism 75, a hinged plate 76, a third receiving drive mechanism 77, a clamping head 78 and a fourth receiving drive mechanism 79; the receiving frame 71 is arranged on the frame 10 and is located beside the output end of the feeding device 30; the movable seat 72 is arranged on the receiving frame 71 so as to be movable back and forth laterally; the first receiving drive mechanism 73 is arranged on the receiving frame 71 and drives the movable seat 72 back and forth movement; the movable plate 74 can be movably arranged on the movable seat 72 up and down; the second material receiving drive mechanism 75 is arranged on the movable seat 72 and drives the movable plate 74 to move up and down back and forth; one end of the hinged plate 76 can be rotatably arranged on the movable plate 74 back and forth; the third material receiving drive mechanism 77 is arranged on the movable plate 74 and drives the hinged plate 76 to rotate; the clamping head 78 can be opened and closed and is arranged at the other end of the hinged plate 76, and the fourth material receiving drive mechanism 79 is arranged on the hinged plate 76 and drives the clamping head 78 to open and close. The receiving device 70 also includes a conveyor assembly 80, which includes a conveyor frame 81, a conveyor belt 82, and a second drive mechanism 83. The conveyor frame 81 is mounted on the frame 10 and located below the receiving frame 71. The conveyor belt 82 is mounted on the conveyor frame 81 so that it can be driven back and forth. The other end of the hinged plate 76 moves back and forth between the output end of the feeding device 30 and the conveyor belt 82. The second drive mechanism 83 is mounted on the conveyor frame 81 and drives the conveyor belt 82 back and forth. When the clamping head 78 removes the cut solar panel, it is placed on the conveyor belt 82 and transported outward.

[0052] The working principle of this embodiment is described in detail as follows:

[0053] During processing, the equipment is first connected to an external power source. The panels to be processed are then fed into the feed chute 301 via an external loading device and positioned using the clamping plate 32. The feed head 34 then drives the panels toward the output end of the feed device 30. Once in position, the CCD lens 36 detects the position of the outermost panel. If the outermost panel deviates toward the output end of the feed device 30, the second pressing drive mechanism 45 drives the correction head 46 to the outside of the outermost panel. The third pressing drive mechanism 47 then drives the correction head 46 downward. The second pressing drive mechanism 45 then drives the correction head 46 toward the inside of the feed device 30, thereby correcting the panel position and ensuring the accuracy of the outermost panel. The correction head 46 then resets and, via the pressing plate 42, presses the panel downward, securing the panel position. The preheating device 50 then preheats the panels from both the top and bottom sides. The cutting device 60 then sequentially cuts the outermost panels from the top and bottom. While cutting, the clamping head 78 clamps the outermost panel. Once cutting is complete, the clamping head 78 places the outermost panel on the conveyor belt 82, which then transports it outward. After cutting a panel, the press plate 42 moves upward and resets, and the above steps are repeated.

[0054] The design focus of the utility model is that: through the arrangement of the feeding device, the pressing device, the cutting device and the receiving device, the cutting and separating process of the battery panel can be realized in an automated manner, which effectively reduces the labor intensity. In addition, the preheating device is arranged on the frame and is located next to the output end of the feeding device, so that the battery panel to be cut is preheated by the preheating device before cutting, thereby reducing the strength of the glue between the two battery panels, thereby facilitating the subsequent cutting process, making the cutting process more convenient and effectively ensuring the cutting efficiency.

[0055] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
