Description

Technical Field

[0001] The utility model relates to the field of battery production, and in particular to a flip assembly and a battery sheet flipping mechanism. Background Art

[0002] In the production process of solar cells, flipping of cells is a key link, especially after the cells are coated with doping layers and before TCO coating, the cells that have completed the doping layer coating need to be transferred from the PECVD equipment to the PVD equipment for TCO coating. However, the traditional cell flipping mechanism mainly uses claws or grooves to clamp the cells. The clamping effect of this method is not ideal. The cells are prone to position displacement during the flipping process, which not only affects production efficiency, but also poses a potential threat to product quality. Although there are related structures that use suction cups to absorb cells, the existing suction cup structures are prone to leave "suction cup marks" on the cells, affecting the surface quality of the cells. Therefore, it has become crucial to improve the existing cell flipping mechanism. Utility Model Content

[0003] In view of this, the utility model provides a flipping assembly and a battery cell flipping mechanism, which innovatively adopts a suction cup to suck the battery cell. The suction cup can accurately locate and absorb the battery cell, ensuring that the position of the battery cell is not easily shifted during the flipping process. Moreover, since the suction cup also includes a pad, the pad is arranged on the battery cell contact surface of the suction cup, so that a buffer is provided between the battery cell and the negative pressure hole, avoiding the "suction cup mark" problem caused by direct contact with the battery cell, thereby ensuring the surface quality of the battery cell.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A flipping assembly includes a flipping unit and a suction cup arranged on the flipping unit and used to adsorb products. The suction cup includes a main body, a negative pressure hole, and a pad. The pad is arranged on the surface of the main body facing the product to be flipped, and the negative pressure hole is arranged in an area on the surface of the main body that is not covered by the pad.

[0006] This flip assembly innovatively uses a suction cup to hold the battery cell. The suction cup can accurately locate and absorb the battery cell, ensuring that the position of the battery cell is not easily displaced during the flipping process, and can effectively avoid damage to the battery cell due to friction or collision during the flipping process, thereby improving the reliability of the entire flip assembly and reducing production errors caused by position deviation. Compared with the traditional mechanical grasping method, the suction cup has a simple structure and low maintenance cost, which reduces the downtime of the production line. In addition, since the suction cup also includes a pad, the pad is arranged on the battery cell contact surface of the suction cup, so that there is a buffer between the battery cell and the negative pressure hole, avoiding the "suction cup mark" problem caused by direct contact with the battery cell, thereby ensuring the surface quality of the battery cell. Due to the combination of the pad and the negative pressure hole, the flip assembly can adapt to battery cells of different sizes and shapes, increasing its wide application.

[0007] Preferably, the flipping unit comprises a rotating shaft and a driver, the driver drives the rotating shaft to rotate, and the suction cup is fixed on the rotating shaft, sucks the product to be flipped and rotates synchronously with the rotating shaft.

[0008] After the suction cup absorbs the product to be flipped, the product can be flipped under the drive of the driver. The flipping angle of the product can be precisely controlled by controlling the driver, making the flipping action accurate and reliable.

[0009] Preferably, a plurality of the suction cups may be provided, and the plurality of suction cups are arranged at equal intervals along the circumference of the rotating shaft to form a suction cup rotating wheel.

[0010] By arranging multiple suction cups and forming a suction cup rotating wheel, the efficiency of flipping the battery cell can be improved. Multiple suction cups are arranged at equal intervals along the rotating shaft to ensure stable transmission of the battery cell during the flipping process.

[0011] Preferably, an air slip ring connected to the suction cup is provided on the rotating shaft, and the air slip ring is connected to an external air source.

[0012] The air slip ring on the rotating shaft is connected to the external air source to provide a stable airflow to the suction cup, which not only ensures the stability of the suction force of the suction cup, but also effectively avoids the problems of airway entanglement and knotting, thereby improving the reliability and durability of the equipment.

[0013] Preferably, the suction cup comprises a body, a negative pressure hole, and a pad, wherein the pad is arranged on the surface of the body facing the battery cell, and the negative pressure hole is arranged in an area on the surface of the body that is not covered by the pad.

[0014] Preferably, the negative pressure holes are arranged along the edges of the long sides of the body, the pads are arranged in the middle of the body, and / or are arranged at intervals along the extension direction of the long sides.

[0015] This is the first negative pressure hole layout scheme. In order to adapt to battery cells of different sizes and shapes and ensure effective adsorption of the battery cells, the negative pressure holes are evenly arranged along the long side edges of the main body, and a pad is arranged in the middle of the main body, which is also an effective suction cup structure. In addition, multiple pads can also be provided, and multiple pads are arranged at intervals along the extension direction of the long side. The negative pressure holes located between two adjacent pads can also ensure effective adsorption of the battery cells.

[0016] Preferably, the negative pressure holes are arranged along the edges of the short sides of the body, the pads are arranged in the middle of the body, and / or are arranged at intervals along the extension direction of the long sides.

[0017] This is the second negative pressure hole layout scheme. Compared with the negative pressure hole layout scheme, this scheme evenly arranges the negative pressure holes along the short side edges of the main body, and arranges a pad in the middle of the main body, which is also an effective suction cup structure. In addition, multiple pads can also be provided, and multiple pads are arranged at intervals along the extension direction of the short side. By using the negative pressure holes located between two adjacent pads, effective adsorption of the battery cells can also be ensured.

[0018] Preferably, the negative pressure holes are arranged along the long and short edges of the main body, and the pad is arranged in the middle of the main body and / or is arranged at intervals along the extension direction of the long and short sides.

[0019] This is the third negative pressure hole layout scheme. The negative pressure holes can be set along the long and short edges of the main body at the same time, forming a complete circle around the edge of the main body, adapting to battery cells of different sizes and shapes, and ensuring effective adsorption of the battery cells.

[0020] Preferably, the negative pressure holes are arranged along the diagonal lines of the main body, and the pads are arranged symmetrically about the center of the main body.

[0021] This is the fourth negative pressure hole layout scheme. The negative pressure holes are arranged along the diagonal lines of the main body, which is also a negative pressure hole layout scheme with good adsorption effect. This layout scheme can also be combined with the aforementioned three layout schemes to form more negative pressure hole layouts to adapt to battery cells of different sizes and shapes to ensure effective adsorption of battery cells.

[0022] Preferably, the suction cup wheels may be provided in plurality, and the plurality of suction cup wheels are connected to the rotating shaft.

[0023] By setting up multiple suction cup wheels and working simultaneously, the processing speed of battery cells can be significantly improved, and the battery cells can be quickly sucked, flipped and transferred, thereby improving the overall throughput of the production line, ensuring the continuous operation of the production line, reducing downtime, and further improving production efficiency.

[0024] Preferably, two suction cup wheels may be provided.

When rotating, the suction cup 30 can be inserted into the hollow part of the conveying runway and the output runway, and the suction cup 30 is used to absorb the battery cell and transfer the battery cell from the conveying runway to the output runway. The rotating shaft 10 and the driver 20 are arranged on the bracket 50. The conveying runway and the output runway are both conventional transmission structures, which can be purchased on the market and are prior art. They are not the invention and innovation of this embodiment, so they are not drawn in the drawings for detailed description.

[0051] The battery cell flipping mechanism innovatively uses a suction cup 30 to hold the battery cell. The suction cup 30 can accurately locate and absorb the battery cell, ensuring that the position of the battery cell is not easily displaced during the flipping process, and can effectively avoid damage to the battery cell due to friction or collision during the flipping process, stably transferring the battery cell from the conveying runway to the output runway, improving the reliability of the entire battery cell flipping mechanism, and reducing production errors caused by position deviation. Compared with the traditional mechanical grasping method, the suction cup 30 has a simple structure, low maintenance cost, and reduces the downtime of the production line.

[0055] The air slip ring 11 on the rotating shaft 10 is connected to the external air source to provide a stable airflow to the suction cup 30, which not only ensures the stability of the adsorption force of the suction cup 30, but also effectively avoids the problems of airway entanglement and knotting, thereby improving the reliability and durability of the equipment.

[0056] In this embodiment, two suction cup wheels 40 are provided.

[0057] By setting two suction cup wheels 40, the two suction cup wheels 40 work at the same time, which can significantly improve the processing speed of the battery cell, and can quickly absorb, flip and transfer the battery cell, thereby improving the overall throughput of the production line, ensuring the continuous operation of the production line, reducing downtime, and further improving production efficiency.

[0059] The pad 33 is arranged on the cell contact surface of the suction cup 30, so that a buffer is provided between the cell and the negative pressure hole 32, avoiding the "suction cup mark" problem caused by direct contact of the cell, thereby ensuring the surface quality of the cell. Due to the combination of the pad 33 and the negative pressure hole 32, the cell flipping mechanism can adapt to cells of different sizes and shapes, increasing its wide application.
