Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module processing, and specifically to an automatic flipping tooling for laser engraving in photovoltaic module production. Background Art

[0002] In the field of new energy, photovoltaic modules are the core units of solar power generation. The processing accuracy of photovoltaic panels directly affects the power generation efficiency and product reliability. With the increasing demand for high-efficiency and intelligent production in the photovoltaic industry, the double-sided engraving process of photovoltaic panels has become an important link in optimizing performance - fine engraving (such as circuit design, structural optimization, etc.) on both the front and back sides of photovoltaic panels can effectively improve the photoelectric conversion efficiency, enhance the mechanical strength, or achieve specific function integration.

[0003] However, traditional double-sided engraving equipment for photovoltaic panels has significant deficiencies: on the one hand, in the single-station processing mode, it is necessary to manually disassemble the photovoltaic panel frequently for turning over, which not only consumes time and effort and has a high labor intensity, but also may cause damage to the photovoltaic panel or the risk of equipment collision due to improper operation; on the other hand, after each single engraving is completed, it is necessary to wait for manual loading and unloading, and the laser engraving machine has a lot of idle time, resulting in low processing efficiency. Summary of the Invention

The driving blocks II are slidably connected in the limit sliding groove.

[0009] Further, linkage seats I and II are respectively fixedly connected and sleeved on the outer sides of the first linkage rod and the second linkage rod. The inner side wall of the second support frame is movably connected to a rotating shaft through a bearing. A first motor for driving the rotating shaft to rotate is fixedly installed on the outer side of the second support frame. A first runner and a second runner are fixedly connected and sleeved on the outer side of the rotating shaft. A first sliding groove and a second sliding groove are respectively provided on both side walls of the first runner and the second runner. The linkage seats I and II are respectively slidably connected to the corresponding first sliding groove and second sliding groove through positioning blocks fixedly connected to their inner side walls.

[0010] Further, a third driving rail is fixedly connected to the side wall of one of the sliding plates. The deflection frame is slidably connected in the third driving rail through the driving block I.

[0011] Further, two second motors and two second fixed cylinders are fixedly installed on the top of one of the sliding plates, and two first fixed cylinders are fixedly installed on the top of the other sliding plate. A first driving shaft is movably connected to the first fixed cylinder through a bearing, and a second driving shaft is movably connected to the second fixed cylinder through a bearing. The first driving shaft and the second driving shaft are respectively fixedly connected to the side wall of the material loading frame. The output end of the second motor is fixedly connected to the end of the second driving shaft.

[0012] Further, through grooves are respectively provided in the top and bottom of the first fixed cylinder, and a sliding frame is slidably connected in the through grooves.

[0013] Further, lifting grooves are respectively provided at the four corners of the top of the frame body. Connecting rods are slidably connected in the lifting grooves. The two ends of the connecting rods are respectively fixedly connected to the bottom of the guide rail group and the top of the lifting seat. The connection parts of the first linkage rod and the second linkage rod with the bearing rod are movably connected through bearings. A laser engraving machine is fixedly installed on the top of the base.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The efficient and automated positioning engraving and alternating processing mechanism is to fix several photovoltaic panels flatly on the loading frame and connect them to the linkage system of the guide rail group. Motor 1 drives the rotating shaft to drive the rotating wheel 1 and the rotating wheel 2 to rotate synchronously, so that the linkage seat 1 and the linkage seat 2 slide along the track in the slide groove through the positioning block, thereby realizing the synchronous lifting and lowering of the guide rail group and the reciprocating sliding of the slide plate.

[0016] When the photovoltaic panel moves with the loading frame to the midpoint of the guide rail group (directly below the laser engraving machine), the guide rail group rises to bring the photovoltaic panel close to the engraving area, and the laser engraving machine starts working immediately after motor one stops; after the single-panel engraving is completed, motor one restarts to drive the unprocessed photovoltaic panel two to the engraving position, and the processed photovoltaic panel one moves out and descends synchronously.

[0017] This mechanism achieves continuous processing of two photovoltaic panels by the laser engraving machine through precise positioning and alternating movement of the dual photovoltaic panels on the guide rail group, avoiding idle waiting of the equipment, upgrading the traditional single-station engraving to a double-station alternating operation mode, and significantly improving the engraving efficiency per unit time.

[0018] 2. Safe and reliable automatic flipping and anti-collision protection design. When the photovoltaic panel moves to both sides of the guide rail group for flipping, the electric push rod drives the sliding frame to disengage the plug-in rod from the first and second plug-in slots, releasing the rotation restriction of the drive shaft one. The motor two drives the loading frame to flip 180 degrees and then re-fix it through the plug-in rod. Combined with the barrier-free design of the flip slot at the bottom of the guide rail group, it ensures that the loading frame does not collide with the laser engraving machine during the flipping process.

[0019] During this process, the photovoltaic panel is lowered to a low position along with the loading frame and turned over. It uses the mechanical structure linkage to achieve automatic turning over without manual disassembly, and uses the dual protection of lifting and position offset to avoid the risk of component interference that may occur when traditional equipment is turned over.

[0020] The "midpoint rise for engraving - both sides drop and flip" circulation mechanism of the dual photovoltaic panels on the guide rail group not only eliminates the tedious process of manual loading and unloading and manual flipping, but also ensures the safety and continuity of the engraving process through the precise coordination of the mechanical structure, significantly improving the degree of automation and processing stability.

[0043] Combining Embodiment 1 and Embodiment 2, the working principle of the present invention is as follows:

[0044] Installation of Photovoltaic Panels and Start of Initial Drive Structure: Name the two photovoltaic panels as Photovoltaic Panel 1 and Photovoltaic Panel 2 respectively. Place Photovoltaic Panel 1 and Photovoltaic Panel 2 horizontally and plug them into the installation slots on the side wall of the loading frame 7. Then, use the knobs at the four corners of the top of the loading frame 7 to quickly fix the photovoltaic panels. Subsequently, start Motor 1 to drive the rotation of the rotating shaft 19. The rotating shaft 19 drives the first runner 20 and the second runner 21 to rotate synchronously. The first linkage seat 181 and the second linkage seat 182 slide in the corresponding first chute and second chute respectively by means of the positioning blocks fixedly connected to their inner side walls.

[0045] Drive Mechanism for Synchronous Lifting of Photovoltaic Panels: The first linkage seat 181 moves along a specific trajectory in the first chute through the positioning block. The first linkage seat 181 drives the first linkage rod 10 and the first drive rail 12 to reciprocally deflect around the bearing rod 9 under the mutual cooperation of the positioning block and the first chute. The lifting seat 5 further drives the guide rail group 4 to lift synchronously through the reciprocating lifting of the connecting rod in the lifting chute under the mutual cooperation of the first linkage block 8 and the first drive rail 12. The guide rail group 4 drives the two photovoltaic panels to lift synchronously.

[0046] Reciprocating Linkage between the Deflection Frame 17 and the Slide Plate 6: The second linkage seat 182 moves along a specific trajectory in the second chute through the positioning block. The second linkage seat 182 drives the second linkage rod 11 and the second drive rail 13 to reciprocally deflect around the bearing rod 9 under the mutual cooperation of the positioning block and the second chute. The lifting rod 15 reciprocally lifts in the limiting cylinder 14 under the mutual cooperation of the second linkage block 16 at its bottom end and the second drive rail 13. The lifting rod 15 further drives the deflection frame 17 to reciprocally deflect through the mutual cooperation of the second drive block at its top and the limiting chute. During the process of the deflection frame 17 reciprocally deflecting, it further drives the slide plate 6 to reciprocally slide in the I-shaped track through the mutual cooperation of the first drive block at the other end and the third drive rail 28.

[0047] First Positioning and Engraving Process of Photovoltaic Panels: When the deflection process of the deflection frame 17 reaches half, at this time, one of the loading frames 7 moves to directly below the laser engraving machine 29. Meanwhile, the guide rail group 4 is further driven to rise synchronously under the mutual cooperation of structures such as the first linkage seat 181, the positioning block, the first chute, the first linkage rod 10, the first drive rail 12, and the lifting seat 5, that is, Photovoltaic Panel 1 and Photovoltaic Panel 2 rise synchronously. At this time, Motor 1 stops, and the laser engraving machine 29 engraves Photovoltaic Panel 1.

[0048] Specific operation of turning over the photovoltaic panel: After the laser engraving of the first photovoltaic panel is completed, the first motor restarts, and the deflecting frame 17 continues to deflect, prompting another unprocessed second photovoltaic panel to move to directly below the laser engraving machine 29, while the first photovoltaic panel that has been processed on only one side moves out from directly below the laser engraving machine 29 and descends. The processed first photovoltaic panel or the photovoltaic panel moves out from directly below the laser engraving machine 29 and makes a descending movement to avoid collision with the laser engraving machine 29 during the flipping process of the loading frame 7 on one side of the guide rail group 4. The electric push rod 26 corresponding to the position of the first photovoltaic panel is activated, and the electric push rod 26 drives the sliding frame 24 to slide in the through groove, and the sliding frame 24 rises relative to the first photovoltaic panel;

[0049] At the same time, the insertion rod 25 disengages from the first insertion slot 27 and the second insertion slot, and at this time, the restricted rotation of the first drive shaft 221 in the first fixed cylinder 22 is released. The second motor drives the first drive shaft 221 to rotate in the first fixed cylinder 22, and further drives the loading frame 7 with the first photovoltaic panel placed thereon to flip 180 degrees until the other second insertion slot of the first drive shaft 221 communicates with the first insertion slot 27 of the first fixed cylinder 22. Subsequently, the electric push rod 26 drives the sliding frame 24 to move in the reverse direction until the insertion rod 25 is inserted into the first insertion slot 27 and the second insertion slot again. At this time, the loading frame 7 drives the first photovoltaic panel to complete a 180-degree flip, and at the same time, it also prompts the loading frame 7 to be re-fixed to prevent self-flipping. It should be explained here that, as Figure 3 shown, flipping grooves are provided on both sides of the bottom of the guide rail group 4 to ensure that the loading frame 7 can flip 180 degrees without interference;

[0050] Efficient cycle of alternating engraving and flipping of double photovoltaic panels: As the first runner 20 and the second runner 21 continue to rotate, the deflecting frame 17 flips to one side and then flips in the opposite direction. At this time, the flipped first photovoltaic panel moves from one side of the guide rail group 4 back to directly below the laser engraving machine 29, while the photovoltaic panel that has been processed on one side moves out from the laser engraving machine 29 and moves to the other side of the guide rail group 4 for flipping. This process repeats until both sides are engraved, and then the first photovoltaic panel and the second photovoltaic panel are disassembled and replaced in sequence, thereby realizing the alternating engraving, alternating flipping, and alternating material replacement of the two photovoltaic panels, reducing the waiting time of the laser engraving machine 29, and improving the engraving efficiency of the photovoltaic module.
