Description

Technical Field

[0001] The present invention relates to the technical field of cell sheet cutting, and in particular to a device for cutting a cell sheet of a photovoltaic panel. Background Art

[0002] Photovoltaic panel cells, as the core components of photovoltaic power generation systems, play a key role in converting solar energy into electrical energy. They are usually made of semiconductor materials such as silicon, and use the principle of photoelectric effect to convert light energy into electrical energy under sunlight. Cells have positive and negative electrodes, and through the design of specific structures, such as aluminum back field cells, passivated emitters and back contact cells, efficient photoelectric conversion is achieved. In the production and manufacturing process of photovoltaic panel cells, cutting is an indispensable link. This step is precise and critical, and usually depends on the application of cell dicing machines. At present, cell dicing machines face many challenges in actual operation, such as the diversity of cell sizes and shapes. Factors such as diversity and slight fluctuations in the focus of the laser beam pose a considerable obstacle to achieving precise cutting. In view of this, in order to ensure the integrity and performance stability of the cell after cutting, the industry generally adopts a compromise strategy - incomplete cutting method, and relies on manual operation to complete the final separation step. In this process, workers need to use their hand strength to directly act on the cell to promote it to break along the preset dicing cutting line. However, this operation method is highly dependent on the worker's power control, operating skills and rich experience, so it is inevitable to encounter problems such as poor cutting consistency and low operating efficiency. For this reason, we propose a cutting device for photovoltaic panel cells. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: a photovoltaic panel cell cutting device, comprising a cutting device body 1, a laser head 2 and a cutting table 3, and also comprising a negative pressure suction cup 4, wherein the negative pressure suction cup 4 is located on the cutting table 3, and the negative pressure suction cup 4 is provided in plurality, and the cell is adsorbed and fixed by using the plurality of negative pressure suction cups 4.

[0036] The fixing component 5 is arranged on the cutting table 3 and is used to drive the negative pressure suction cup 4 to adsorb and fix the battery sheet.

[0037] The advantage of the fixing component 5 is that the battery cell can be adsorbed and fixed by the negative pressure suction cup 4 when the battery cell is cut. The negative pressure suction cup 4 can firmly adsorb the battery cell to prevent displacement caused by vibration or external force interference during the cutting process, thereby improving the cutting accuracy. When fixing the battery cell, the negative pressure suction cup 4 will not cause scratches or indentations on the surface of the battery cell, thereby 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, thereby improving the versatility and adaptability of the equipment. Not only that, 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 to meet the needs of different application scenarios.

[0038] The separation component 9 is arranged on the fixing component 5, and the separation component 9 is used to drive the negative pressure suction cup 4 to drive the battery cell after laser cutting to deflect, so as to control the incompletely cut battery cell to be separated along the 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 accurately controlled to realize automated operation, reduce manual intervention, and improve cutting efficiency. Moreover, through the deflection control of the negative pressure suction cup 4, the battery cell can be separated smoothly and without damage, thus avoiding the breakage of the battery cell or performance degradation caused by improper cutting.

[0040] The fixing assembly 5 includes an adjusting member 6 arranged on the cutting table 3, and the adjusting member 6 is used to adjust the distance between the negative pressure suction cups 4. The adjusting member 6 is provided with a mounting member 7, and the negative pressure suction cups 4 are installed and fixed by the mounting member 7. The mounting member 7 is provided with a balancing member 8, and the balancing member 8 is used to control the negative pressure suction cups 4 to remain horizontal.

[0041] The adjusting member 6 comprises a fixed bin 61 arranged on the cutting table 3, wherein sliding grooves 62 are provided on both sides of the fixed bin 61, wherein a plurality of adjusting rods 63 are slidably provided in the sliding grooves 62, wherein an adjusting groove 64 is provided on the adjusting rod 63, wherein a plurality of sliding blocks 65 are slidably provided in the adjusting grooves 64.

[0042] The advantage of setting the adjustment part 6 is that the negative pressure suction cup 4 can be flexibly adjusted according to different battery cell sizes and cutting requirements, thereby 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 to meet the needs of different application scenarios.

[0043] The mounting member 7 comprises a circular plate 71 arranged on the sliding block 65, the circular plate 71 is provided with a vertical rod 72, the vertical rod 72 is provided with a universal joint 73, the universal joint 73 is connected to the negative pressure suction cup 4, the negative pressure suction cup 4 is provided with an air pipe 74, and the air pipe 74 is externally connected to an air suction device.

[0044] The balancing member 8 includes a positioning rod 81 arranged on the circular plate 71, and a support rod 82 is arranged on the positioning rod 81. The top of the support rod 82 is made of rubber material, and the support rod 82 is threadedly connected to the positioning rod 81. A fixing plate 83 is arranged on the vertical rod 72, and the fixing plate 83 is movably connected to the support rod 82. A plurality of recovery tubes 84 are arranged on the fixing plate 83, and a support rod 86 is slidably arranged in the recovery tube 84. A support spring 85 is arranged in the recovery tube 84, and the support spring 85 is connected to the support rod 86.

[0045] The advantage of setting up the balance member 8 is that it can always keep the negative pressure suction cup 4 in a horizontal state, and when separating the battery cells, the negative pressure suction cup 4 can be deflected in multiple directions. 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 replace the negative pressure suction cup 4 or adjust the position of the equipment, and can complete the separation task by simply controlling the deflection of the negative pressure suction cup 4.

[0046] Before cutting the battery cell, adjust the positions of the adjusting rod 63 and the sliding block 65 according to the cutting needs, so that the negative pressure suction cup 4 can match the battery cell after cutting. The adjusting rod 63 and the sliding block 65 need to be pushed manually 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 the existing technology, so it will not be elaborated here. The initial heights of the support rod 1 82 and the support rod 2 86 are consistent, so the horizontality of the negative pressure suction cup 4 can be ensured by pushing the plate 101.

[0047] The separation assembly 9 includes a separation member 10 arranged on a circular plate 71, and the separation member 10 is used to drive the negative pressure suction cup 4 to deflect. A switching member 11 is arranged on the fixed bin 61, and the deflection direction of the negative pressure suction cup 4 is adjusted by the switching member 11. A driving member 12 is arranged on the fixed bin 61, and the driving member 12 is used to drive the switching member 11 to work.

[0048] The separator 10 includes a push plate 101 arranged on the universal joint 73, a plurality of limit grooves 102 are arranged on the vertical rod 72, a limit rod 103 is arranged on the support rod 82, the limit rod 103 is slidably connected with the limit groove 102, a separation gear 104 is arranged at the bottom of the positioning rod 81, an annular plate 105 is rotatably arranged on the circular plate 71, and a plurality of groups of rotating latch teeth 106 are arranged in the annular plate 105.

[0049] The advantage of setting up the separator 10 is that when separating incompletely cut battery cells, manual separation is not required, but the battery cells are separated by deflecting the negative pressure suction cup 4. The deflection of the negative pressure suction cup 4 to drive the separation of the battery cells can achieve fast and continuous separation actions, greatly improving production efficiency. In comparison, manual separation requires more time and manpower, and the separation speed is affected by human factors, and it is 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, due to improper operation or inaccurate force control, the battery cell is easily damaged, affecting the quality and performance of the battery cell.

[0050] The switching member 11 includes a mounting plate 111 disposed at both ends of the adjusting rod 63, the mounting plate 111 is provided with a moving groove 112, a plurality of moving blocks 113 are slidably disposed in the moving groove 112, a plurality of worms 114 are rotatably disposed on the moving blocks 113, a worm wheel 115 engaged with the worm 114 is disposed on the annular plate 105, a moving screw 116 is rotatably disposed in the moving groove 112, the moving screw 116 penetrates the plurality of moving blocks 113 and is threadedly connected to the moving blocks 113, and the moving screw 116 is provided with a plurality of moving blocks 113. A switching gear 117 is provided, and a switching rod 118 is slidably provided in the movable groove 112. The switching rod 118 is provided with a plurality of switching teeth 119 that engage with the switching gear 117. A plurality of positioning blocks 1111 are provided on the fixed bin 61. A synchronization rod 1110 is rotatably provided on the positioning blocks 1111. The synchronization rod 1110 passes through a plurality of mounting plates 111 and a movable screw rod 116. The synchronization rod 1110 is movably connected to the mounting plates 111, and the synchronization rod 1110 is slidably connected to the movable screw rod 116.

[0051] The advantage of setting up the switching member 11 is that it can allow the negative pressure suction cup 4 to deflect in multiple directions when separating battery cells. The negative pressure suction cup 4 can deflect in multiple directions, which means that it can adapt to the separation requirements of battery cells in different directions and angles. This design enables 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. The multi-directional deflection design simplifies the operating steps of battery cell separation. Workers do not need to frequently replace the negative pressure suction cup 4 or adjust the equipment position. They only need to control the deflection of the negative pressure suction cup 4 to complete the separation task.

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

[0053] When separating the battery cells, first push the driving handle 121 on one side to drive the driving handle 121 to slide on one side of the worm 114, and simultaneously push the rotating plate 122 to move. The movement of the rotating plate 122 drives the switching rod 118 connected thereto to move in the moving groove 112. The movement of the switching rod 118 drives the switching tooth 119 to move. The movement of the switching tooth 119 drives the moving screw rod 116 to rotate. The rotation of the moving screw rod 116 drives the moving block 113 to slide in the moving groove 112, so that the worm 114 on one side is close to the worm wheel 115, while the worm 114 on the other side is away from the worm wheel 115, so as to avoid affecting the normal rotation of the worm wheel 115. The rotation of the annular plate 105 drives the rotation of the annular plate 105, and the rotation of the annular plate 105 drives the rotation of the rotating tooth 106 set on its inner ring to move. During the displacement process, the rotating tooth 106 drives the separation gear 104 engaged therewith to rotate, and the rotation of the separation gear 104 drives the positioning rod 81 to rotate. The positioning rod 81 rotates to push the support rod 82 threadedly connected therewith to extend, and pushes the pushing 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. When the separation on one side is completed, the control switch rod 118 and the negative pressure suction cup 4 are reset, and then the driving handle 121 on the other side is rotated to drive the suction cup 4 to rotate in the other direction.

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

[0055] A wedge block 13 is provided in the fixed bin 61, and a discharge port 14 is provided on the fixed bin 61. After the battery cells are separated, the negative pressure suction cup 4 is controlled by the controller to stop working, and the fixation of the battery cells is released, so that the separated battery cells fall into the fixed bin 61 and slide out through the discharge port 14 under the action of the wedge block 13.

[0056] When in use, before cutting the battery cell, adjust the positions of the adjusting rod 63 and the sliding block 65 according to the cutting needs, so that the negative pressure suction cup 4 can match the battery cell after cutting. The adjusting rod 63 and the sliding block 65 need to be pushed manually 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 the existing technology, so it will not be elaborated here. The initial heights of the support rod 1 82 and the support rod 2 86 are the same, so the horizontality of the negative pressure suction cup 4 can be ensured by pushing the plate 101, and then start laser cutting.

[0057] After the laser cutting is completed, the battery cells are separated. First, the driving handle 121 on one side is pushed to drive the driving handle 121 to slide on one side of the worm 114, and the rotating plate 122 is pushed to move synchronously. The rotating plate 122 moves to drive the switching rod 118 connected thereto to move in the moving groove 112. The switching rod 118 moves to drive the switching tooth 119 to move. The switching tooth 119 moves to drive the moving screw 116 to rotate. The moving screw 116 rotates to drive the moving block 113 to slide in the moving groove 112, so that the worm 114 on one side is close to the worm wheel 115, while the worm 114 on the other side is away from the worm wheel 115, so as to avoid affecting the normal rotation of the worm wheel 115. The rotation of the worm gear 115 drives the annular plate 105 to rotate, and the rotation of the annular plate 105 drives the rotating latch 106 set on its inner ring to move. During the displacement process, the rotating latch 106 drives the separation gear 104 engaged with it to rotate, and the rotation of the separation gear 104 drives the positioning rod 81 to rotate. The positioning rod 81 rotates to push the support rod 82 threadedly connected to it to extend, and pushes the pushing 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. When the separation on one side is completed, the control switch rod 118 and the negative pressure suction cup 4 are reset, and then the driving handle 121 on the other side is rotated to drive the suction cup 4 to rotate in the other direction.

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

[0059] After the battery cells are separated, the controller controls the negative pressure suction cup 4 to stop working, releases the fixation of the battery cells, and allows the separated battery cells to fall into the fixing bin 61 and slide out through the discharge port 14 under the action of the wedge block 13 .

[0060] Example 2: Please refer to Fig.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 colliding with the wedge block 13 when it falls and causing damage to the battery cell.
