Technical Field

[0001] This utility model belongs to the field of solar cell processing technology, specifically relating to a cutting device that can adapt to the thickness of solar cells. Background Technology

[0002] Solar cells are classified into crystalline silicon and amorphous silicon. Crystalline silicon cells can be further divided into monocrystalline cells and polycrystalline cells. The efficiency of monocrystalline silicon cells also differs from that of polycrystalline silicon cells.

[0003] During the production process of solar cells, it is usually necessary to scribe the entire cell into scribe lines, and then cut the entire cell into several cell units along the scribe lines. Laser cutting equipment can be used in the cutting process of solar cells.

[0004] Existing cutting devices require fixing the position of solar cells during the cutting process. When fixing the position of solar cells of different thicknesses, manual adjustment is required, which is time-consuming and labor-intensive, thus affecting the processing efficiency of solar cells. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device that can adapt to the thickness of solar cells, in order to solve the problem that existing cutting devices require manual adjustment when fixing the position of solar cells of different thicknesses, which is time-consuming and labor-intensive and thus affects the processing efficiency of solar cells.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for adaptive solar cell thickness, comprising a cutting machine table, a laser cutter, an XY-axis moving platform and a fixed base, wherein the laser cutter is mounted on the upper surface of the cutting machine table, the XY-axis moving platform is mounted on the upper surface of the cutting machine table, and the fixed base is mounted on the upper surface of the XY-axis moving platform;

[0007] A first telescopic rod is installed on the side surface of the fixed base. A connecting plate is connected to the telescopic end of the first telescopic rod. A positioning post is connected to the lower surface of the connecting plate. A pressure sensor is installed at the bottom of the positioning post. A rubber seat is connected to the bottom of the pressure sensor. A wire is connected between the positioning post and the first telescopic rod. A control switch is installed in the middle of the wire.

[0008] To facilitate control of the rubber seat position, in a preferred embodiment of the cutting device for adapting to the thickness of solar cells according to this utility model, the first telescopic rod and the connecting plate are symmetrically arranged on both sides of the fixed seat, and the connecting plate and the first telescopic rod form a lifting structure.

[0009] To facilitate the control of the operation of the first telescopic rod via a pressure sensor, in the preferred embodiment of this invention, a cutting device for adapting to the thickness of solar cells, the pressure sensor and the first telescopic rod are electrically connected via wires.

[0010] To facilitate the placement of solar cells, as a preferred embodiment of the cutting device of this invention that can adapt to the thickness of solar cells, a feeding base is installed on the upper surface of the cutting machine table, and a feeding rack is connected to the upper surface of the feeding base.

[0011] To facilitate automatic feeding of solar cells, as a preferred embodiment of the cutting device of this utility model that can adapt to the thickness of solar cells, a second telescopic rod is installed on the side surface of the cutting machine table, the telescopic end of the second telescopic rod is connected to a mounting frame, a third telescopic rod is installed on the upper surface of the mounting frame, and the telescopic end of the third telescopic rod is connected to a pusher plate.

[0012] In a preferred embodiment of the cutting device for adaptive solar cell thickness according to this utility model, the mounting frame and the second telescopic rod form a telescopic structure, the pusher plate is L-shaped, and the pusher plate and the third telescopic rod form a telescopic structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the first telescopic rod can drive the connecting plate to move downwards during operation. The downward movement of the connecting plate can drive the rubber seat to move downwards through the positioning column and pressure sensor. When the pressure value of the pressure sensor reaches the set value, the first telescopic rod can be stopped by the control switch. This can accommodate solar cells of different thicknesses for fixed position, and at the same time avoid excessive squeezing force that could damage the solar cells.

[0015] In this invention, solar cells are first stacked sequentially on the upper surface of the feeding base inside the feeding rack. When the third telescopic rod is in motion, it can drive the pusher plate to move upward. Then, when the second telescopic rod is in motion, it can drive the mounting frame to move laterally. When the mounting frame moves laterally, it can drive the pusher plate to move laterally through the third telescopic rod. The lateral movement of the pusher plate can squeeze the solar cells to move laterally. When the solar cells are squeezed, they can move laterally to the upper surface of the fixed base, thereby realizing the automatic feeding of solar cells. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a cutting device for adapting to the thickness of solar cells, including a cutting machine table 1, a laser cutter 2, an XY axis moving platform 3 and a fixed base 4. The laser cutter 2 is installed on the upper surface of the cutting machine table 1, the XY axis moving platform 3 is installed on the upper surface of the cutting machine table 1, and the fixed base 4 is installed on the upper surface of the XY axis moving platform 3.

[0025] A first telescopic rod 5 is installed on the side surface of the fixed base 4. A connecting plate 6 is connected to the telescopic end of the first telescopic rod 5. A positioning post 7 is connected to the lower surface of the connecting plate 6. A pressure sensor 8 is installed at the bottom of the positioning post 7. A rubber seat 9 is connected to the bottom of the pressure sensor 8. A wire 10 is connected between the positioning post 7 and the first telescopic rod 5. A control switch 17 is installed in the middle of the wire 10.

[0026] Preferably, the first telescopic rod 5 and the connecting plate 6 are symmetrically arranged on both sides of the fixed base 4, and the connecting plate 6 and the first telescopic rod 5 form a lifting structure.

[0027] In practical use, when the first telescopic rod 5 is running, it can drive the connecting plate 6 to move downward. The downward movement of the connecting plate 6 can drive the rubber seat 9 to move downward through the positioning column 7 and the pressure sensor 8, thereby facilitating the fixation of the solar cell position.

[0028] Preferably, the pressure sensor 8 and the first telescopic rod 5 are electrically connected by a wire 10.

[0029] In practical use, when the downward pressure value of the pressure sensor 8 reaches the set value, the pressure sensor 8 can control the first telescopic rod 5 to stop operating through the control switch 17.

[0030] Preferably, a feeding base 11 is installed on the upper surface of the cutting machine table 1, and a feeding rack 12 is connected to the upper surface of the feeding base 11.

[0031] In practical use, solar cells can be stacked sequentially on the upper surface of the feeding base 11 inside the feeding rack 12.

[0032] Preferably, a second telescopic rod 13 is installed on the side surface of the cutting machine table 1, the telescopic end of the second telescopic rod 13 is connected to a mounting frame 14, a third telescopic rod 15 is installed on the upper surface of the mounting frame 14, and the telescopic end of the third telescopic rod 15 is connected to a pusher plate 16.

[0033] In practical use, the third telescopic rod 15 can be extended during operation. The extension of the third telescopic rod 15 can drive the pusher plate 16 to move upward. At this time, the vertical plate of the pusher plate 16 is located on the side of the bottom solar cell. At this time, the horizontal movement of the pusher plate 16 can drive the solar cell to move horizontally.

[0034] Preferably, the mounting bracket 14 and the second telescopic rod 13 form a telescopic structure, the pusher plate 16 is L-shaped, and the pusher plate 16 and the third telescopic rod 15 form a telescopic structure.

[0035] In practical use, the second telescopic rod 13 can drive the mounting frame 14 to move laterally when it runs. When the mounting frame 14 moves laterally, it can squeeze the solar cell to move laterally through the third telescopic rod 15 and the pusher plate 16, thereby realizing the automatic feeding of solar cell.

[0036] Working principle: When using this cutting device that can adapt to the thickness of solar cells, the solar cells are first stacked on the upper surface of the feeding base 11 in the feeding rack 12. When feeding, the third telescopic rod 15 is activated first. The third telescopic rod 15 can extend when it runs. The extension of the third telescopic rod 15 can drive the pusher plate 16 to move upward. At this time, the vertical plate of the pusher plate 16 is located on the side of the bottom solar cell. Then the second telescopic rod 13 is run. When the second telescopic rod 13 runs, it can drive the mounting frame 14 to move laterally. When the mounting frame 14 moves laterally, it can drive the pusher plate 16 to move laterally through the third telescopic rod 15. The lateral movement of the pusher plate 16 can squeeze the solar cells to move laterally. The solar cells are squeezed and can move laterally to the upper surface of the fixed base 4.

[0037] When the solar cell is fully moved to the upper surface of the fixed base 4, the first telescopic rod 5 can be activated. When the first telescopic rod 5 retracts, it can drive the connecting plate 6 to move downward. The downward movement of the connecting plate 6 can drive the positioning column 7 to move downward. The downward movement of the positioning column 7 can drive the pressure sensor 8 to move downward. The downward movement of the pressure sensor 8 can drive the rubber seat 9 to move downward. When the downward pressure value of the pressure sensor 8 reaches the set value, the pressure sensor 8 can control the first telescopic rod 5 to stop running through the control switch 17. This can fix the position of the solar cell and avoid damage to the solar cell due to excessive squeezing force.

[0038] Then, the position of the solar cell can be controlled by the XY axis moving platform 3, and the solar cell can be cut by the laser cutter 2. After the solar cell is cut, the individual solar cell is removed. Then, the third telescopic rod 15 retracts. When the third telescopic rod 15 retracts, it can drive the pusher plate 16 to move downward. Then, the second telescopic rod 13 drives the mounting frame 14 to retract. When the mounting frame 14 retracts, it can drive the third telescopic rod 15 and the pusher plate 16 to move to the original position and reload.
