Description

Technical Field

[0001] This invention relates to the field of solar cell cutting technology, specifically to a cutting device for photovoltaic solar cells. Background Technology

[0002] Photovoltaic (PV) solar cells, as the core component of photovoltaic (PV) power generation systems, play a crucial role in converting solar energy into electrical energy. They are typically made of semiconductor materials such as silicon and utilize the photoelectric effect to convert light energy into electrical energy under sunlight. Each cell has positive and negative electrodes, and through specific structural designs, such as aluminum back-field cells, passivated emitters, and back-contact cells, efficient photoelectric conversion is achieved. Cutting is an indispensable step in the manufacturing process of PV cells. This precise and critical step usually relies on the application of a cell dicing machine. Currently, cell dicing machines face many challenges in actual operation, such as the varying sizes and shapes of the cells. The diversity of materials and subtle fluctuations in the laser beam's focal point pose significant obstacles to achieving precise cutting. Therefore, to ensure the integrity and performance stability of the cut solar cells, the industry generally adopts a compromise strategy—incomplete cutting—relying on manual operation to complete the final separation step. In this process, workers must directly apply force to the solar cells with their hands, causing them to break along the pre-set dicing lines. However, this method is highly dependent on the worker's strength control, operating skills, and extensive experience, inevitably leading to problems such as poor cutting consistency and low work efficiency. To address this, we propose a cutting device for photovoltaic solar cells. Summary of the Invention

[0034] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-11 The present invention provides a technical solution: a cutting device for photovoltaic cell, including a cutting device body 1, a laser head 2 and a cutting table 3, and also includes a negative pressure suction cup 4, wherein the negative pressure suction cup 4 is located on the cutting table 3, and multiple negative pressure suction cups 4 are provided, and the cell is adsorbed and fixed by the multiple negative pressure suction cups 4.

[0036] Fixing component 5 is set on the cutting table 3, and the fixing component 5 is used to drive the negative pressure suction cup 4 to adsorb and fix the battery cell.

[0037] The advantage of the fixing component 5 is that it can adsorb and fix the battery cells during the cutting process using the negative pressure suction cup 4. The negative pressure suction cup 4 can firmly hold the battery cells, preventing displacement caused by vibration or external interference during the cutting process, thereby improving the cutting accuracy. When fixing the battery cells, the negative pressure suction cup 4 will not cause scratches or indentations on the surface of the battery cells, thus avoiding the mechanical damage that may be caused by traditional clamps. At the same time, the design of the negative pressure suction cup 4 allows it to be flexibly adjusted according to different battery cell sizes and cutting requirements, improving the versatility and adaptability of the equipment. Moreover, by precisely controlling the deflection angle and force of the negative pressure suction cup 4, the battery cells can be accurately separated along the preset cutting line, meeting the needs of different application scenarios.

[0038] Separation component 9 is mounted on fixed component 5. The separation component 9 drives negative pressure suction cup 4 to deflect the laser-cut battery cell, thereby controlling the incompletely cut battery cell to separate along a preset cutting line.

[0039] The advantage of setting up the separation component 9 is that after the laser head 2 completes the cutting of the battery cell, the incompletely cut battery cell can be separated along the preset cutting line by controlling the deflection of the negative pressure suction cup 4. By controlling the deflection of the negative pressure suction cup 4, the separation process of the battery cell can be precisely controlled, realizing automated operation, reducing manual intervention, and improving cutting efficiency. Moreover, by controlling the deflection of the negative pressure suction cup 4, the battery cell can be separated smoothly and without damage, avoiding the breakage or performance degradation of the battery cell caused by improper cutting.

[0040] The fixing component 5 includes an adjusting member 6 disposed on the cutting table 3, which is used to adjust the spacing between the negative pressure suction cups 4. The adjusting member 6 is provided with an mounting member 7, which is used to install and fix the negative pressure suction cups 4. The mounting member 7 is provided with a balancing member 8, which is used to control the negative pressure suction cups 4 to remain horizontal.

[0041] The adjusting component 6 includes a fixed chamber 61 disposed on the cutting table 3. The fixed chamber 61 has sliding grooves 62 on both sides. Multiple adjusting rods 63 are slidably disposed in the sliding grooves 62. Adjusting grooves 64 are disposed on the adjusting rods 63. Multiple sliding blocks 65 are slidably disposed in the adjusting grooves 64.

[0042] The advantage of setting the adjustment component 6 is that it allows the negative pressure suction cup 4 to be flexibly adjusted according to different battery cell sizes and cutting requirements, improving the versatility and adaptability of the equipment. Moreover, by precisely controlling the deflection angle and force of the negative pressure suction cup 4, the battery cells can be accurately separated along the preset cutting line, meeting the needs of different application scenarios.

[0043] Mounting component 7 includes a circular plate 71 mounted on a sliding block 65, a vertical rod 72 mounted on the circular plate 71, a universal joint 73 mounted on the vertical rod 72, the universal joint 73 being connected to a negative pressure suction cup 4, and an air pipe 74 mounted on the negative pressure suction cup 4, with an external suction device connected to the air pipe 74.

[0044] The balancing component 8 includes a positioning rod 81 mounted on a circular plate 71. A support rod 82 is mounted on the positioning rod 81. The top end of the support rod 82 is made of rubber. The support rod 82 is threadedly connected to the positioning rod 81. A fixing plate 83 is mounted on the upright 72. The fixing plate 83 is movably connected to the support rod 82. Multiple recovery tubes 84 are mounted on the fixing plate 83. A support rod 86 is slidably mounted inside each recovery tube 84. A support spring 85 is mounted inside each recovery tube 84 and is connected to the support rod 86.

[0045] The advantage of the balancing component 8 is that it can keep the negative pressure suction cup 4 in a horizontal position at all times, and can deflect the negative pressure suction cup 4 in multiple directions when separating the battery cells. This design allows the negative pressure suction cup 4 to adjust its posture more flexibly during the separation process, ensuring that the battery cells can be accurately separated along the preset cutting line or separation path. Workers do not need to frequently change the negative pressure suction cup 4 or adjust the position of the equipment. They can complete the separation task simply by controlling the deflection of the negative pressure suction cup 4.

[0046] Before cutting the battery cells, adjust the positions of the adjusting rod 63 and the sliding block 65 according to the cutting requirements so that the negative pressure suction cup 4 can match the cut battery cells. The adjusting rod 63 and the sliding block 65 need to be manually pushed to slide in the sliding groove 62 and the adjusting groove 64, which will not affect the stability of the negative pressure suction cup 4. After the adjustment is completed, place the battery cell on the negative pressure suction cup 4, start the controller to drive the negative pressure suction cup 4 to work, and firmly adsorb the battery cell. The working principle of the negative pressure suction cup 4 is existing technology, so it will not be described in detail here. The initial height of the support rod 1 82 and the support rod 2 86 is the same, so the level of the negative pressure suction cup 4 can be ensured by the push plate 101.

[0047] The separation component 9 includes a separation element 10 disposed on the circular plate 71, which drives the negative pressure suction cup 4 to deflect. A switching element 11 is disposed on the fixed chamber 61, which adjusts the deflection direction of the negative pressure suction cup 4. A driving element 12 is disposed on the fixed chamber 61, which drives the switching element 11 to work.

[0048] The separating component 10 includes a push plate 101 mounted on a universal joint 73, a plurality of limiting grooves 102 provided on the upright 72, a limiting rod 103 provided on the support rod 82, the limiting rod 103 being slidably connected to the limiting grooves 102, a separating gear 104 provided at the bottom of the positioning rod 81, and an annular plate 105 rotatably mounted on the circular plate 71, with a plurality of sets of rotating retaining teeth 106 provided inside the annular plate 105.

[0049] The advantage of the separator 10 is that when separating incompletely cut battery cells, manual separation is not required. Instead, the negative pressure suction cup 4 is used to deflect and separate the battery cells. The deflection of the negative pressure suction cup 4 to separate the battery cells can achieve fast and continuous separation, which greatly improves production efficiency. In contrast, manual separation requires more time and manpower, and the separation speed is affected by human factors, making it difficult to ensure consistency. At the same time, the deflection separation method of the negative pressure suction cup 4 can handle the battery cells more gently, reducing the risk of battery cell damage caused by physical impact or improper operation. During manual separation, improper operation or inaccurate force control can easily damage the battery cells, affecting their quality and performance.

[0050] The switching component 11 includes mounting plates 111 disposed at both ends of the adjusting rod 63. The mounting plates 111 have movable grooves 112, and multiple movable blocks 113 are slidably disposed within the movable grooves 112. Multiple worm gears 114 are rotatably disposed on the movable blocks 113. A worm wheel 115, engaging with the worm gears 114, is disposed on the annular plate 105. A movable lead screw 116 is rotatably disposed within the movable grooves 112. The movable lead screw 116 passes through the multiple movable blocks 113 and is threadedly connected to the movable blocks 113. The movable lead screw 116... A switching gear 117 is provided, and a switching rod 118 is slidably disposed in the moving groove 112. The switching rod 118 is provided with a plurality of switching teeth 119 that mesh with the switching gear 117. A plurality of positioning blocks 1111 are provided on the fixed chamber 61. A synchronizing rod 1110 is rotatably disposed on the positioning block 1111. The synchronizing rod 1110 passes through a plurality of mounting plates 111 and a moving lead screw 116. The synchronizing rod 1110 is movably connected to the mounting plate 111 and slidably connected to the moving lead screw 116.

[0051] The advantage of the switching component 11 is that it allows the negative pressure suction cup 4 to deflect in multiple directions during cell separation. The ability of the negative pressure suction cup 4 to deflect in multiple directions means that it can adapt to the cell separation requirements of different directions and angles. This design allows the negative pressure suction cup 4 to adjust its posture more flexibly during the separation process, ensuring that the cells can be accurately separated along the preset cutting line or separation path. The multi-directional deflection design simplifies the operation steps of cell separation. Workers do not need to frequently change the negative pressure suction cup 4 or adjust the equipment position; they can complete the separation task simply by controlling the deflection of the negative pressure suction cup 4.

[0052] The driving component 12 includes a driving handle 121 slidably mounted on a plurality of worm gears 114, a rotating plate 122 mounted on the switching rod 118, the rotating plate 122 being movably connected to the worm gears 114 and rotatably connected to the driving handle 121, a driving gear 123 mounted on the worm gears 114, a sliding rod 124 slidably mounted on the fixed chamber 61, a multi-stage telescopic rod 125 mounted on the sliding rod 124, a bearing rod 126 mounted on the multi-stage telescopic rod 125, a buffer spring 127 sleeved on the multi-stage telescopic rod 125, and a driving rack 128 on the bearing rod 126 that meshes with the driving gear 123.

[0053] When separating the battery cells, first push the drive handle 121 on one side, causing it to slide on the side of the worm gear 114. Simultaneously, push the rotating plate 122 to move. The movement of the rotating plate 122 causes the switching rod 118 connected to it to move within the moving groove 112. The movement of the switching rod 118 causes the switching tooth 119 to move, which in turn causes the moving screw 116 to rotate. The rotation of the moving screw 116 causes the moving block 113 to slide within the moving groove 112, so that one side of the worm gear 114 is closer to the worm wheel 115, while the other side is further away from the worm wheel 115, thus avoiding affecting the normal rotation of the worm wheel 115. The rotation of the ring plate 105 causes the ring plate 105 to rotate, which in turn causes the rotating tooth 106 located on its inner ring to move. During the displacement, the rotating tooth 106 drives the separation gear 104 that meshes with it to rotate. The rotation of the separation gear 104 drives the positioning rod 81 to rotate. The rotation of the positioning rod 81 pushes the support rod 82, which is threaded to it, to extend and push the push plate 101 and the universal joint 73 to deflect, thereby pushing the negative pressure suction cup 4 to deflect to separate the incompletely cut battery cells. After the separation on one side is completed, the control switching rod 118 and the negative pressure suction cup 4 are reset. Then, the drive handle 121 on the other side is rotated to drive the suction cup 4 to rotate in the other direction.

[0054] As the worm gear 114 rotates, it drives the drive gear 123 mounted on it to rotate synchronously. The rotation of the drive gear 123 drives the drive rack 128 meshing with it to move. The movement of the drive rack 128 drives the bearing rod 126 and the sliding rod 124 to move synchronously on the fixed chamber 61, thereby driving multiple drive racks 128 to move synchronously. The movement of the drive racks 128 drives multiple drive gears 123 to rotate synchronously, thereby driving multiple negative pressure suction cups 4 to deflect synchronously.

[0055] A wedge block 13 is provided inside the fixed chamber 61, and a discharge port 14 is provided on the fixed chamber 61. After the separation of the battery cells is completed, the negative pressure suction cup 4 is stopped by the controller to release the battery cells, so that the separated battery cells fall into the fixed chamber 61 and slide out through the discharge port 14 under the action of the wedge block 13.

[0056] Before cutting the battery cells, adjust the positions of the adjusting rod 63 and the sliding block 65 according to the cutting requirements so that the negative pressure suction cup 4 can match the cut battery cells. Both the adjusting rod 63 and the sliding block 65 need to be manually pushed to slide in the sliding groove 62 and the adjusting groove 64, which will not affect the stability of the negative pressure suction cup 4. After the adjustment is completed, place the battery cells on the negative pressure suction cup 4, start the controller to drive the negative pressure suction cup 4 to work, and firmly adsorb the battery cells. The working principle of the negative pressure suction cup 4 is existing technology, so it will not be described in detail here. The initial heights of the support rod 1 82 and the support rod 2 86 are the same, so the level of the negative pressure suction cup 4 can be ensured by the push plate 101. Then the laser cutting begins.

[0057] After laser cutting is completed, the separation of the battery cells begins. First, the drive handle 121 on one side is pushed, causing it to slide on one side of the worm gear 114. Simultaneously, the rotating plate 122 is moved. The movement of the rotating plate 122 causes the switching rod 118 connected to it to move within the moving groove 112. The movement of the switching rod 118 causes the switching tooth 119 to move, which in turn causes the moving screw 116 to rotate. The rotation of the moving screw 116 causes the moving block 113 to slide within the moving groove 112, so that one side of the worm gear 114 is closer to the worm wheel 115, while the other side is further away from the worm wheel 115, thus avoiding interference with the normal rotation of the worm wheel 115. The rotation of the worm gear 115 drives the annular plate 105 to rotate. The rotation of the annular plate 105 drives the rotating tooth 106 located on its inner ring to move. During the displacement, the rotating tooth 106 drives the separation gear 104 meshing with it to rotate. The rotation of the separation gear 104 drives the positioning rod 81 to rotate. The rotation of the positioning rod 81 pushes the support rod 82 threadedly connected to it to extend, and pushes the push plate 101 and universal joint 73 to deflect, thereby pushing the negative pressure suction cup 4 to deflect to separate the incompletely cut battery cells. After the separation on one side is completed, the control switching rod 118 and the negative pressure suction cup 4 are reset. Then, the drive handle 121 on the other side is rotated to drive the suction cup 4 to rotate in the other direction.

[0058] As the worm gear 114 rotates, it drives the drive gear 123 mounted on it to rotate synchronously. The rotation of the drive gear 123 drives the drive rack 128 meshing with it to move. The movement of the drive rack 128 drives the bearing rod 126 and the sliding rod 124 to move synchronously on the fixed chamber 61, thereby driving multiple drive racks 128 to move synchronously. The movement of the drive racks 128 drives multiple drive gears 123 to rotate synchronously, thereby driving multiple negative pressure suction cups 4 to deflect synchronously.

[0059] After the separation of the battery cells is completed, the negative pressure suction cup 4 is stopped by the controller, the battery cells are released from the fixation, and the separated battery cells fall into the fixed chamber 61 and slide out through the discharge port 14 under the action of the wedge block 13.

[0060] Example 2: Please refer to Figure 12 The present invention provides a technical solution: the wedge block 13 is made of rubber and has a smooth surface. The advantage of this design is that it can prevent the battery cell from being damaged when it falls and collides with the wedge block 13.
