The processing table 1 is equipped with a limit frame 14, a vertical feeding component, a rotating roller 2, a first drive component 201, a support roller 3, and a second drive component 301. (Specifically, both the first drive component 201 and the second drive component 301 are driven by gears. The gear transmission is shown in the figure but is not specifically labeled. Its driving principle is prior art and will not be described.)

[0032] The vertical feeding component is positioned between two opposing limiting frames 14 so that several photovoltaic cells stacked together can move upward at equal intervals under the limiting of the limiting frames 14.

[0033] The rotating roller 2 is rotatably connected to the processing table 1 and is connected to the first drive assembly 201. One end of the rotating roller 2 is connected to the mounting frame 21, and the mounting frame 21 is symmetrically provided with feeding adsorption and transfer assemblies.

[0034] The support roller 3 is rotatably connected to the turntable 31 via a bearing, and the turntable 31 is connected to the second drive assembly 301. Several cutting tables 32 are arranged on the circumference of the turntable 31.

[0035] Two sets of feeding, adsorption and transfer components are positioned directly above the vertical feeding component and one of the cutting tables 32, respectively, so that a single photovoltaic cell is automatically transferred from the vertical feeding component to the cutting table 32 of the feeding station;

[0036] The cutting table 32 has several adsorption holes 33, and the adsorption holes 33 are connected to the positioning adsorption components set inside the cutting table 32.

[0037] The upper end of the support roller 3 extends to the upper side of the turntable 31 and is equipped with a pushing and unloading component. The pushing and unloading component cooperates with several cutting tables 32 in sequence to automatically unload the photovoltaic cells after laser cutting.

[0038] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the vertical feeding assembly includes an electric push rod 12 and a support plate 13. The processing table 1 has an installation groove 11, in which the electric push rod 12 is installed. The electric push rod 12 is connected to the support plate 13, which is located between two limit frames 14 and is spaced apart from the limit frames 14.

[0039] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the feeding adsorption and transfer assembly includes an electric cylinder 22 and an electric suction cup 23. The electric cylinder 22 is symmetrically arranged on the mounting frame 21. The electric cylinder 22 is connected to the electric suction cup 23. The two electric suction cups 23 are respectively located directly above the support plate 13 and the cutting table 32 of the feeding station.

[0040] Further refinements of the embodiments of this utility model, such as... Figure 3As shown, the positioning adsorption assembly includes an adsorption box 34 and an air pump 35. The cutting table 32 has an installation cavity inside. The top of the installation cavity is fixed with the hollow adsorption box 34. The adsorption box 34 has several suction holes that correspond one-to-one with the adsorption holes 33. The adsorption box 34 is connected to the air pump 35 fixed in the installation cavity. The input end of the air pump 35 is connected to the outside. The suction holes are not shown in the figure.

[0041] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 4 As shown, the push-out component includes a cylinder 41 and a push plate 42. The support roller 3 is provided with a cylinder 41 at the end away from the processing table 1. The cylinder 41 is connected to a push plate 42 that is flush with the upper surface of the cutting table 32.

[0042] A further optimization of the embodiment of this utility model is that a conveyor belt is provided on one side of the processing table 1, which is lower in height than the cutting table 32 at the unloading station and is distributed directly opposite to it at intervals. This embodiment is not shown in the figure.

[0043] It should be noted that the electric push rod 12, the first drive assembly 201, the second drive assembly 301, the electric cylinder 22, the electric suction cup 23, the air pump 35, and the air cylinder 41 are all electrically connected to the controller, which is not shown in the figure.

[0044] The working process of this utility model:

[0045] First, the photovoltaic cells are neatly stacked in batches between two limiting frames 14 (the limiting frames 14 can limit the position of the photovoltaic cells). After stacking, the cells can be automatically loaded, laser-cut and unloaded on the processing table 1.

[0046] In the initial state, the two electric suction cups 23 are respectively located above the support plate 13 and the cutting table 32 of the loading station. Then, the controller controls the electric cylinder 22 located above the support plate 13 to work and drive the electric suction cup 23 connected to it to move down to a preset height. When the electric suction cup 23 has finished descending, it comes into contact with the photovoltaic cell at the top and can then be adsorbed. After adsorption, the cell is driven to move up to the initial height.

[0047] Then the controller controls the first drive component 201 to work, thereby causing the two electric suction cups 23 to exchange positions (i.e., the mounting bracket 21 rotates 180 degrees). At the same time, the controller controls the electric push rod 12 to move up a pre-set distance so that the next photovoltaic cell moves to the initial height of the previous photovoltaic cell. Then the above process can be repeated to adsorb another photovoltaic cell using another electric suction cup 23.

[0048] During the adsorption of the second photovoltaic cell, the electric suction cup 23 above the cutting table 32 is driven by the electric cylinder 22 to move down to a pre-set height (the descent height of the same electric suction cup 23 is different before and after changing positions and is pre-set in the controller). When the bottom surface of the first photovoltaic cell comes into contact with the cutting table 32, the controller can immediately control the electric suction cup 23 on that side to be de-energized (the other electric suction cup 23 continues to maintain adsorption without being affected). Then the first photovoltaic cell is detached from the electric suction cup 23 and automatically transferred to the cutting table 32 without offset.

[0049] After the first photovoltaic cell is transferred onto the cutting table 32 at the loading station, the controller immediately activates the air pump 35 inside the cutting table 32 to ensure a firm grip on the photovoltaic cell. Then, the controller activates the second drive assembly 301, causing the next cutting table 32 without a photovoltaic cell to move to that position (the turntable 31 rotates counter-clockwise). At this point, the cutting table 32 with the photovoltaic cell already placed and gripped moves directly below the laser cutter at the laser cutting station and pauses. The drive assembly then drives the laser cutter to cut the photovoltaic cell (neither the drive assembly nor the laser cutter is shown in the figure; the drive assembly is specifically a three-axis device, specifically mounted on the processing table 1).

[0050] As the first photovoltaic cell begins laser cutting, the second photovoltaic cell can be transferred to the cutting table 32 at the loading station through the process described above. By repeating the above process, the automatic loading of photovoltaic cells onto several cutting tables 32 and the laser cutting process can be realized.

[0051] Since there are four cutting stations 32 on the turntable 31, three of which are for loading, laser cutting and unloading, the photovoltaic cell will automatically move to the unloading station after the first photovoltaic cell is cut. At this time, the controller first controls the air pump 35 inside the cutting station 32 to stop, and then the cylinder 41 works to drive the push plate 42 to push the photovoltaic cell away from the conveyor belt so as not to affect the loading process of the subsequent new photovoltaic cells. In summary, the accurate loading, laser cutting and automatic unloading process of photovoltaic cells can be automatically completed on the processing platform.

[0052] Compared to existing technologies, this processing platform can automatically load photovoltaic cells onto the cutting table 32. After loading, there is no need to adjust the orientation of the photovoltaic cells. The placement of the photovoltaic cells onto the cutting table 32 is uniform and accurate. After placement, the platform can automatically and firmly adhere to the photovoltaic cells. Then, the cutting table 32 moves to the laser cutting station and the unloading station to complete the processing and unloading process. At the same time, this processing platform can realize the assembly line processing of photovoltaic cells, thereby significantly reducing the labor intensity of manual operation. The alternating operation of the two sets of loading, adsorption and transfer components can significantly improve work efficiency.

[0053] In some embodiments, such as Figure 2 As shown, a lightweight flexible material 15 is provided on the inner side of the limiting frame 14, and a chamfer 16 adapted to the photovoltaic cell is provided on the lightweight flexible material 15.

[0054] In a further refinement of the above embodiment, a lightweight flexible material 15 is provided at the bottom of the push plate 42;

[0055] Furthermore, the cutting table 32 is also provided with a lightweight flexible material 15, and the lightweight flexible material 15 has through holes that connect to the adsorption holes 33; the above embodiment can reduce the wear on the surface of the photovoltaic cells during the loading and unloading process by contacting the lightweight flexible material 15, and automatically complete the loading and unloading while providing good protection for the photovoltaic cells.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
