Description

Technical Field

[0001] This invention relates to the technical field of solar cell production, specifically to a laser cutting machine for solar cells. Background Technology

[0002] Solar cells are a key component of solar power generation devices. They need to be cut during the production process. Currently, most technologies involve manually placing the cells under a laser cutting machine, which then cuts them using a laser. This manual positioning not only wastes time but also reduces cutting efficiency.

[0003] To overcome the above-mentioned defects, existing technology 1 (Chinese Patent Publication No. CN220161533U, Publication Date: December 12, 2023) discloses a laser cutting machine for solar cells, which includes a frame assembly and a laser cutting assembly disposed on the table of the frame assembly. The laser cutting assembly includes an X-axis drive mechanism, a Y-axis drive mechanism, and a laser cutting head. The Y-axis drive mechanism is fixedly mounted on a first movable seat of the X-axis drive mechanism, and the laser cutting head is fixedly mounted on a second movable seat of the Y-axis drive mechanism. A positioning fixture assembly is provided below the Y-axis drive mechanism. The positioning fixture assembly includes a support frame, a fixture plate assembly, a fixture seat, and a clamping mechanism for fixing the fixture seat. The fixture plate assembly is mounted on the fixture seat and includes a positioning frame and a core plate. The core plate is installed in the inner cavity of the positioning frame. The positioning frame is provided with a positioning insert and a positioning push block. This utility model can be applied to the laser cutting of solar cells of different specifications. This invention has broad applicability. Existing technology two (Chinese patent publication number CN118513681A, publication date August 20, 2024) describes a laser cutting machine for solar cells, including a protective shell. Inside the protective shell is a support plate, and inside the support plate are multiple circumferentially distributed slide tracks. Positioning blocks are slidably connected inside each slide track, penetrating the top and bottom of the support plate. Each slide track has a buffer mechanism, and the bottom of the support plate has a traction mechanism. When cutting solar cells, this invention uses the support plate to feed the solar cells into the protective shell, allowing the entire cutting process to take place inside the protective shell. This effectively avoids injury to workers caused by the laser cutting device. Furthermore, the circumferentially distributed positioning blocks position the solar cells, ensuring cutting accuracy and eliminating the need for manual positioning, thus effectively improving the cutting efficiency of solar cells.

[0004] While existing technologies employ multi-axis drive for cutting control to improve overall cutting efficiency, the multi-axis drive increases the complexity of the overall structure and raises production and testing time costs. Furthermore, the protective casing not only causes heat buildup, affecting the quality of cell cutting, but also makes the overall structure difficult to observe, thus affecting cutting accuracy.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on existing laser cutting machines used for solar cells. Therefore, we propose a laser cutting machine for solar cells that can effectively solve these problems. Summary of the Invention

[0013] Preferably, the output end of the gas cylinder is connected to the inner cavity of the temporary storage box through a second pipe, the inner cavity of the temporary storage box is provided with a baffle, the other side of the temporary storage box is connected to the inner cavity of the cleaning box through a third pipe, the cleaning box is installed inside the base, and the cleaning box is connected to the external environment through a pipe.

[0014] Preferably, a gas supply hood is installed at the bottom of the temporary storage box. The gas supply hood is connected to two inner cavities of the temporary storage box via pipes, and electrically controlled valves are installed on the pipes. An auxiliary component is installed at the bottom of the temporary storage box. The auxiliary component includes a second telescopic rod installed at the bottom of the temporary storage box. The inner cavity of the second telescopic rod is connected to an external air pump via an intermittent pipe. A third spring is installed on the outer side of the second telescopic rod.

[0015] Preferably, the machine base is provided with a suction hood, which is located outside the workbench and is connected to the inner cavity of the cleaning box through a negative pressure pipe.

[0016] Compared with the prior art, the beneficial effects of this invention are: the laser cutting machine for solar cells uses a robotic arm on the base to quickly move the laser cutter to the required cutting position, improving overall efficiency; the monitoring device solves the problem of the protective cover affecting cutting accuracy in existing devices; air cooling and liquid cooling maintain the temperature of the solar cells, improving cutting quality; and the overall structure is simple, solving the problem of increased cost caused by the complexity of existing structures. The specific details are as follows: (1) By driving the turntable and rotating parts through the drive motor, the moving block drives the clamping seat to clamp the battery cell evenly from the side wall. At the same time, the moving block is linked with the first conveying cylinder and the telescopic rod, so that the electromagnetic block and the ordinary magnetic block attract each other to form a negative pressure adsorption, thereby achieving dual fixation of side wall clamping and negative pressure adsorption, which improves the overall cutting quality.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: In this example, the cooling medium in the temporary storage box 5 flows through a pipe into the heat dissipation sleeve 7 on the outside of the laser cutter 6, providing heat dissipation for the laser cutter 6 and the monitoring component, effectively maintaining the stable operating temperature of the laser cutter 6 and the monitoring component. Figures 1-7The technical solution shown includes a base 1, a worktable 2 on the base 1, a support 3 for limiting the position of solar cells mounted on the worktable 2, a laser cutting assembly on the base 1, a robotic arm 4 mounted on the base 1, a temporary storage box 5 on the robotic arm 4, a laser cutter 6 and a monitoring device mounted below the temporary storage box 5, a dual-axis motor 8 and a cooling box 11 installed inside the base 1, a delivery pump 9 connected to the first output end of the dual-axis motor 8, an input end of the delivery pump 9 connected to the inside of the cooling box 11 via a delivery pipe 10, an output end of the delivery pump 9 connected to the inner cavity of the support 3 via the delivery pipe 10, and the inner cavity of the support 3 connected to the inside of the cooling box 11 via a return pipe 12. A clamping device is mounted on the worktable 2. The laser cutter 6 has a heat dissipation sleeve 7 on its outer side, which is connected to the inner cavity of the temporary storage box 5 via a pipe, and an electrically controlled valve is installed on the pipe. The clamping assembly includes a drive motor 13 installed in the worktable 2. The output end of the drive motor 13 is connected to a turntable 14. A moving block 16 is connected to the turntable 14 via a rotating component 15. The rotating component 15 is set at equal angles. A limit groove 17 is opened on the worktable 2, and the moving block 16 is movably connected inside the limit groove 17. A clamping seat 18 for limiting the sidewall of the solar cell is installed on the moving block 16. The solar cell to be cut is placed on the support base 3 of the worktable 2. At this time, the drive motor 13 starts and drives the turntable 14 to rotate. Since the rotating component 15 on the turntable 14 is hinged to the moving block 16, the solar cell is rotated. The rotating component 15, set at equal angles, pulls the moving block 16 along the limiting groove 17, causing the clamping seat 18 to clamp the battery cell from the side wall, thereby limiting the battery cell. The overall clamping force is uniform and stable, effectively preventing damage or displacement of the battery cell due to uneven force, ensuring subsequent cutting accuracy. The mechanical arm 4 on the machine base 1 drives the temporary storage box 5 to move. The mechanical arm 4 allows the laser cutter 6 to move quickly to the required cutting position, improving overall efficiency. The laser cutter 6 aligns with the battery cell to perform cutting. The monitoring component monitors the cutting status in real time, which can promptly detect cutting deviations and breakpoints, facilitating quick adjustments by the operator, reducing the defect rate, and solving the problem of the existing device's protective cover affecting cutting accuracy. The dual-axis motor 8 is turned on. One output terminal drives the delivery pump 9, which delivers the coolant in the cooling tank 11 to the inner cavity of the support base 3 through the delivery pipe 10. This cools the bottom of the battery cell, preventing damage caused by the high temperature during cutting and ensuring a smooth cut surface. The coolant returns to the cooling tank 11 via the return pipe 12 for recycling, reducing resource waste and production costs. The cooling medium in the temporary storage box 5 flows through a pipe into the heat dissipation sleeve 7 on the outside of the laser cutter 6, providing heat dissipation for the laser cutter 6 and the monitoring components. This effectively maintains the stable operating temperature of the laser cutter 6 and the monitoring components, preventing performance degradation or shortened lifespan due to high temperatures. Furthermore, the through holes on the outside of the heat dissipation sleeve 7 facilitate air blowing for cleaning, promptly removing dust from the cutting area.To avoid dust accumulation affecting cutting quality and monitoring clarity, the overall structure is simple, solving the problem of increased costs caused by the complexity of existing structures.

[0025] Example 2: In this example, the rubber gasket at the end of the negative pressure cylinder 24 enhances the fixing effect with the surface of the battery cell. In addition to the sidewall clamping, negative pressure adsorption is added to achieve double fixing, further improving the positioning stability of the battery cell. Specifically, as follows... Figures 5-8 As shown, the following is disclosed: a first conveying cylinder 19 is installed inside the workbench 2, and a piston is connected through the first conveying cylinder 19. The bottom side of the moving block 16 is connected to the piston. A first telescopic rod 21 is installed inside the clamping seat 18. The cavity of the first conveying cylinder 19 located on the other side of the piston is connected to the inner cavity of the first telescopic rod 21 through a first pipe 20. A first spring 22 for rebound is provided on the outer side of the first telescopic rod 21. An electromagnetic block 23 is connected to the end of the first telescopic rod 21. Adsorption components are provided on opposite sides of the clamping seat 18. The adsorption components include components installed on opposite sides of the clamping seat 18. The negative pressure cylinder 24 has a piston connected through it, and a common magnetic block 25 is installed at the end of the piston. A second spring 26 is set on the outside of the piston. The common magnetic block 25 is magnetically attracted to the electromagnetic block 23. A contact piece 27 is installed on the side of the moving block 16. A contact seat 28 is installed inside the limiting groove 17. The contact piece 27 is located on the side of the contact seat 28. The contact seat 28 is electrically connected to the electromagnetic block 23 through a wire 29. When the moving block 16 moves, the bottom of the moving block 16 drives the piston in the first conveying cylinder 19 to move. The gas inside the first conveying cylinder 19 is directed to the first pipe 20. The first telescopic rod 21 applies pressure, causing the first telescopic rod 21 to extend through the first spring 22, bringing the electromagnetic block 23 closer to the ordinary magnetic block 25. When the moving block 16 moves, the contact piece 27 at its side end touches the contact seat 28 in the limiting groove 17. The electromagnetic block 23 is energized through the wire 29, attracting the ordinary magnetic block 25 at the side end of the negative pressure cylinder 24. This pulls the piston inside the negative pressure cylinder 24, creating negative pressure. This enhances the fixing effect between the rubber gasket at the end of the negative pressure cylinder 24 and the surface of the battery cell. In addition to the side wall clamping, negative pressure adsorption is added, achieving double fixing and further improving the positioning of the battery cell. For stability, the second spring 26 on the outside of the piston inside the negative pressure cylinder 24 is used for subsequent reset, improving the continuity of operation. After the moving block 16 completes the clamping of the battery cell, it moves to all sides, the contact piece 27 moves out of the surface of the contact seat 28, and the overall electrical connection is disconnected. At the same time, the piston inside the first conveying cylinder 19 moves in the opposite direction, drawing the gas back into the first pipe 20 through the first telescopic rod 21, causing the first telescopic rod 21 to shorten. The electromagnetic block 23 is disconnected from the ordinary magnetic block 25, and the negative pressure in the negative pressure cylinder 24 is released. The overall response is rapid, which not only ensures the reliability of the fixation, but also avoids the negative pressure residue affecting the picking and placing of the battery cell.

[0026] Example 3: In this example, the cooling tank 11 is simultaneously supplied with external cold gas. This provides a stable gas source for cold gas delivery, and the flow of cold gas through the cooling tank 11 helps to lower the coolant temperature and improve the cooling effect. Specifically, as follows... Figure 2 and Figures 9-12As shown, the following is disclosed: a crankshaft 30 is connected to the second output end of the dual-shaft motor 8; an air supply cylinder 31 is installed inside the base 1; a piston connected to the crankshaft 30 passes through the air supply cylinder 31; the input end of the air supply cylinder 31 is connected to the top of the cooling box 11 via a pipe; the top of the cooling box 11 is connected to external cold gas via a pipe; the output end of the air supply cylinder 31 is connected to the inner cavity of the temporary storage box 5 via a second pipe 32; a baffle is provided inside the temporary storage box 5; the other side of the temporary storage box 5 is connected to the inner cavity of the cleaning box 34 via a third pipe 33; the cleaning box 34 is installed inside the base 1; the cleaning box 34 is connected to the external environment via a pipe; an air supply hood 35 is installed at the bottom of the temporary storage box 5; the air supply hood 35 is connected to the two inner cavities of the temporary storage box 5 via pipes, and the pipes are connected to the air supply cylinder 34. An electrically controlled valve is installed. An auxiliary component is mounted at the bottom of the temporary storage box 5. This auxiliary component includes a second telescopic rod 36 installed at the bottom of the temporary storage box 5. The inner cavity of the second telescopic rod 36 is connected to an external air pump via an intermittent pipe 37. A third spring 38 is installed on the outer side of the second telescopic rod 36. A compression plate 39 is installed at the end of the second telescopic rod 36, located on the side of the air supply hood 35. A rotating shaft passes through the air supply hood 35, and a torsion spring 40 is sleeved on the outer side of the rotating shaft. An air suction hood 42 is installed on the base 1, located outside the workbench 2. The air suction hood 42 is connected to the inner cavity of the cleaning box 34 via a negative pressure pipe 41. When the dual-axis motor 8 is in use, its second output end drives the crankshaft 30 to rotate, driving the piston inside the air supply cylinder 31 to reciprocate, from the top of the cooling box 11. Cold gas is drawn in, and the cooling box 11 is simultaneously supplied with external cold gas. This provides a stable gas source for cold gas delivery and helps reduce the coolant temperature by flowing through the cooling box 11, thus improving the cooling effect. The cold gas is then delivered to one side of the temporary storage box 5 through the second pipe 32. This facilitates heat dissipation inside the heat sink 7, enhancing the heat dissipation efficiency of the laser cutter 6 and monitoring components. Furthermore, the gas can be blown towards the cutting area through the gas delivery hood 35, removing dust generated during cutting and providing secondary cooling to the cutting area, further ensuring the quality of the battery cells. When dust needs to be removed, the valve on one side of the pipe is closed and a negative pressure pipe structure is connected. The gas delivery hood 35 can then switch to adsorption mode, adsorbing the dust from the cutting area to the other side of the temporary storage box 5. The dust is then further cooled by the second pipe 32. The three pipes 33 introduce the cleaning box 34 for filtration. The cleaning box 34 is connected to the external environment to discharge clean gas, realizing centralized dust collection and treatment, avoiding dust pollution of the environment and equipment. At the same time, the suction hood 42 on the outside of the workbench 2 adsorbs the surrounding diffused dust through the negative pressure pipe 41, and also introduces it into the cleaning box 34 for treatment, expanding the dust collection range and improving the dust removal effect. The external air pump is started, and pressure is delivered to the second telescopic rod 36 through the intermittent pipe 37. With the help of the third spring 38, the extrusion plate 39 is pushed to squeeze the air conveying hood 35, causing the air conveying hood 35 to rotate through the rotating shaft. The torsion spring 40 on the outside of the rotating shaft assists the air conveying hood 35 to rotate at multiple angles, increasing the blowing and suction range, improving the comprehensiveness of dust cleaning and area cooling, and improving the overall work efficiency and practicality.
