Technical Field

[0002] In today's energy field, solar energy, as a clean and renewable energy source, has received extensive attention and application. Solar cells are the core components that convert solar energy into electrical energy, and their performance and quality directly determine the efficiency and reliability of solar power generation systems.

[0003] In the prior art, when the cell is cut by splitting, the cell must be cut before splitting. However, when the cell is cut by a laser cutter, high temperature will be generated, which will cause the performance of the cell material to degrade. At the same time, after the cell is split, the uneven split area will cause the appearance quality of the split area to be substandard and the electrical performance will be lost. Therefore, to solve the above problems, we provide a cell and a production device thereof. Summary of the invention

[0031] Furthermore, the length of the first rack is twice the distance between the center of the first gear and the center of the second gear.

[0032] By setting the length of the first rack to twice the distance between the center of the first gear and the center of the second gear, when the first rack leaves the first gear, the first rack only drives the second gear to rotate 90°, thereby better cooperating with the splinter grinding device.

[0039] By setting up an air bag and several spray heads, when the laser cutter is cutting the gap in the battery cell, the several spray heads can spray liquid onto the bottom surface of the battery cell, thereby preventing the temperature of the battery cell from rising due to cutting by the laser cutter, thereby causing a decrease in material properties and damage to mechanical properties.

[0040] Furthermore, the liquid in the liquid storage box is deionized water.

[0050] The grinding belt is sleeved on the rotating roller and the rotating shaft of the grinding motor, and the grinding surface of the grinding belt faces the inner top surface of the shell.

[0051] By setting a third gear, a second rack, a base plate, a grinding motor, a rotating bracket, a rotating roller, a grinding belt, and a vertical sliding groove, when the retained cut area of ​​the battery cell contacts the grinding belt, the grinding belt can grind the split cut area of ​​the battery cell, thereby removing cracks and damaged parts, reducing surface roughness, enhancing the mechanical properties of the battery cell and optimizing the electrical properties of the battery cell.

[0052] Furthermore, the grinding belt is a rubber grinding belt.

[0053] By making the grinding belt out of rubber, the grinding belt has excellent elasticity and resilience, and can provide a good buffering effect when rising. When the grinding belt contacts the cell crack area, the elasticity of the rubber can make the contact between the grinding belt and the crack area softer, disperse the impact force, and avoid direct impact on the crack.

The cutting device will cut a folding gap in the battery cell, and when the cutting device is started, it will drive the cooling device to operate, so as to cool the cut battery cell. When the user controls the cutting device to restore, the cutting device will drive the automatic splitting device to operate, and split and break the battery cell with the folding gap cut out. At the same time, it will drive the splitting grinding device to approach the retained part of the broken battery cell, and grind the cut area of ​​the retained part of the battery cell to complete the processing of the battery cell.

[0056] This working method achieves the following technical effects: when the device is performing folding slit cutting on the battery cell, the device will automatically cool down the battery cell. After the cutting is completed, the device will automatically break the battery cell into pieces and polish the cut area of ​​the battery cell after the splitting is completed.

By arranging the first rack, the first gear, the second gear, the first pulley, the second pulley, the transverse sliding groove, the tension spring, the rotating rod, the first rack and the first gear, the first carrier plate can break the cut battery cells into pieces at a uniform speed when the driving motor is reversed, thereby avoiding manual breaking of the battery cells, which may cause the battery cells to break.

[0111] A battery cell, which is a conventional crystalline silicon battery cell.

[0112] Working process: When the user wants to cut the battery cell into pieces, the user first places several battery cells on the first carrier plate 205 and the second carrier plate 206, wherein the retained part of the battery cell is placed on the first carrier plate 205, and the discarded part of the battery cell is placed on the second carrier plate 206, and the space between the first carrier plate 205 and the second carrier plate 206 is the cutting area of ​​the battery cell. Then the user activates the electromagnetic suction cups on the first carrier plate 205 and the second carrier plate 206 through the controller to fix the battery cell. After the battery cell is fixed, the grinding motor 504 and the laser cutter 201 are activated through the controller, and the drive motor 202 is activated to rotate forward. After the drive motor 202 is activated to rotate forward, the drive motor 202 drives the threaded rod 203 to rotate forward, and the threaded rod 203 rotates forward to drive the connecting sleeve 204 to move forward, and drives the first pulley 304 to rotate. The movement of the connecting sleeve 204 drives the laser cutter 201 to move until the laser cutter 201 moves above the cutting area of ​​the battery cell. When the laser cutter 201 is started and moves above the cutting area of ​​the battery cell, the laser cutter 201 cuts the surface of the battery cell, thereby cutting out a folded gap, until the laser cutter 201 leaves the area where the battery cell is located.

[0113] When the first pulley 304 rotates, the first pulley 304 rotates through the belt to drive the second pulley 305 to rotate, the second pulley 305 rotates to drive the second connecting rod 208 to rotate, the second connecting rod 208 rotates to drive the second gear 303 to rotate and drive the cam 404 to rotate, and the rotation of the cam 404 can continuously contact and move away from the airbag 401. When the cam 404 contacts the airbag 401, the airbag 401 is squeezed to transport the plasma water inside the airbag 401 to the delivery pipe 403, and then sprayed to the bottom surface of the cutting area of ​​the battery cell through a plurality of spray heads 402, so as to cool down the cutting area of ​​the battery cell being cut, avoid damaging the performance of the battery cell material, and at the same time damage its working performance. When the cam 404 leaves the airbag 401, the airbag 401 stops being squeezed and recovers, and the airbag 401 will transport the plasma water inside the storage tank to the inside of the airbag 401 again, waiting for the next contraction of the airbag 401.

[0114] When the second gear 303 rotates forward, the second gear 303 rotates forward and drives the first rack 301 to move along the transverse sliding groove 306 in a direction away from the first gear 302. When the first rack 301 moves, it compresses the tension spring 307. After the tension spring 307 is shortened, it accumulates pressure and waits for release. When the first rack 301 moves under the drive of the second gear 303 and stops meshing with the second gear 303, the first rack 301 stops applying pressure to the tension spring 307. When the tension spring 307 stops being subjected to pressure, it releases the elastic force. The tension spring 307 drives the first rack 301 to move in a direction close to the first gear 302 until it meshes with the second gear 303 again. At this time, the second gear 303 rotates forward and still drives the first rack 301 to move along the transverse sliding groove 306 in a direction away from the first gear 302.

[0115] When the folding gap cutting of the battery cell is completed and the laser cutter 201 leaves the area where the battery cell is located, the user can control the laser cutter 201 to close and control the drive motor 202 to reverse through the controller. The drive motor 202 reverses to drive the threaded rod 203 to reverse, and the threaded rod 203 reverses to drive the connecting sleeve 204 to move backward, and drives the first pulley 304 to reverse. The connecting sleeve 204 moves backward and drives the laser cutter 201 to move backward until the connecting sleeve 204 moves to the initial position, and then stops the drive motor 202 from rotating.

[0116] When the first pulley 304 reverses, the first pulley 304 reverses and drives the second pulley 305 to reverse through the belt, and the second pulley 305 reverses and drives the second connecting rod 208 to reverse, and the second connecting rod 208 reverses and drives the second gear 303 to reverse and drives the cam 404 to rotate. When the second gear 303 reverses and the tension spring 307 releases the elastic force to drive the first rack 301 to mesh with the second gear 303 again, the second gear 303 reverses and drives the first rack 301 to move along the transverse sliding groove 306 toward the direction close to the first gear 302, and at the same time, the first rack 301 moves and pulls the tension spring 307 to lengthen, and drives the first gear 302 to reverse when it contacts the first gear 302, and the first gear 302 reverses and drives the first connecting rod 207 to rotate, and the first connecting rod 207 rotates and drives the first carrier plate 205 to rotate 90 degrees and drives the third gear 501 to rotate, so that the cutting area of ​​the retained part of the battery cell is facing the top surface of the grinding belt 507.

[0117] When the tension spring 307 is stretched and the first rack 301 stops meshing with the second gear 303, the tension spring 307 will retract and drive the first rack 301 to move toward the direction close to the second gear 303 and mesh with the second gear 303 again. The rotation of the second gear 303 will drive the first rack 301 to move toward the direction close to the first gear 302 again.

[0118] The cam 404 rotates to continuously contact and move away from the airbag 401. When the cam 404 contacts the airbag 401, the airbag 401 is squeezed to transport the plasma water inside the airbag 401 to the delivery pipe 403, and then sprayed to the bottom surface of the cutting area of ​​the battery cell through a plurality of spray heads 402, so as to cool down the cutting area of ​​the battery cell being cut, avoid damaging the performance of the battery cell material, and at the same time damage its working performance. When the cam 404 leaves the airbag 401, the airbag 401 stops being squeezed and recovers, and the airbag 401 will transport the plasma water inside the liquid storage box to the inside of the airbag 401 again, waiting for the next contraction of the airbag 401.

[0119] When the third gear 501 rotates, the third gear 501 rotates and drives the second rack 502 to move upward, the third rack moves upward and drives the base plate 503 to move upward, the base plate 503 moves upward and drives the grinding motor 504 and the rotating bracket 505 to move upward, the rotating bracket 505 and the grinding motor 504 move upward and drive the grinding belt 507 to move upward until the grinding belt 507 moves and contacts the cutting area of ​​the retained part of the battery cell, and grinds the cutting area of ​​the retained part of the battery cell, so that the cutting area of ​​the retained part of the battery cell can be smooth, thereby optimizing the electrical performance of the battery cell and improving the appearance quality.

[0120] When the cutting area of ​​the reserved part of the battery cell is polished and collected, and the connecting sleeve 204 is restored to its original position under the drive of the threaded rod 203, the user can stop the driving motor 202. After the driving motor 202 stops, the threaded rod 203 stops rotating and stops the first pulley 304, which stops the second pulley 305, which stops the second pulley 305, which stops the second connecting rod 208, and the second gear 303 stops rotating after the second connecting rod 208 stops rotating. When the second gear 303 stops rotating, and the tension spring 307 drives the first rack 301 to move toward the direction of the second gear 303 and meshes with the second gear 303 again, the first rack 301 will drive the second gear 303 to rotate until the first rack 301 returns to its original position. At this time, the user can place the second batch of battery cells on the first carrier plate 205 and the second carrier plate 206, waiting for the next processing.
