Description

Technical Field

[0001] This invention belongs to the field of battery cell packaging line technology, and more specifically, relates to an automatic battery cell packaging line. Background Technology

[0002] Solar cells are generally classified into monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Monocrystalline silicon solar cells are currently the fastest-developing type of solar cell. Their structure and manufacturing process are well-established, and the products are widely used in space and on the ground. These solar cells use high-purity monocrystalline silicon rods as raw materials. To reduce production costs, ground-based solar cells use solar-grade monocrystalline silicon rods, with relaxed material performance specifications. Some may also use end-products and waste monocrystalline silicon materials from semiconductor device processing, which are then re-drawn into monocrystalline silicon rods specifically for solar cells.

[0003] Currently, equipment automation is a key indicator for measuring the level of automation in a production line and a crucial guarantee of product quality and performance. With the development of the electronics industry and the rapid growth of the solar energy industry in recent years, there is a significant need for fully automated production equipment. In existing technologies, after the solar cells are manufactured and packaged, the material boxes are typically collected manually from the sorting machine onto the packaging line. This method requires a large workforce, is labor-intensive, inefficient, and easily results in breakage.

[0004] For example, CN108372962A describes a fully automated battery cell packaging line and method. The fully automated packaging line is located after a sorting machine. The sorting machine includes a full-pack conveyor mechanism for conveying full packs and an empty-pack conveyor mechanism for conveying empty packs. The fully automated packaging line includes a full-pack conveyor platform for conveying full packs, a packaging platform, an empty-pack conveyor platform for conveying empty packs, and AGVs (Automated Guided Vehicles) for automatically conveying full packs from the full-pack conveyor mechanism to the full-pack conveyor platform and automatically conveying empty packs from the empty-pack conveyor platform to the empty-pack conveyor mechanism. This fully automated packaging line eliminates human intervention throughout the entire process, from loading and unloading at the sorting machine to the delivery of the battery cells to the packaging platform. This reduces the breakage rate during battery cell production, improves the overall efficiency of the equipment, and simultaneously reduces labor intensity and saves manpower.

[0005] However, in actual use, the sorting device cannot be used when most of the battery cells are of different lengths. The packaging line needs to be stopped to replace the sorting device, which requires a lot of manpower, is labor-intensive, and affects the packaging efficiency of the packaging line. Summary of the Invention

[0023] The technical effects achieved by this invention are as follows:

[0024] (1) By setting up a sorting mechanism, when the length of the battery cell to be packaged changes, the number of sorting plates protruding from the side wall of the sorting roller is adjusted by the extension and retraction of the sorting plate driven by the first electric push rod. This allows for the sorting of battery cells of different lengths without the need to replace the sorting device. This enables the sorting device to match more specifications of battery cells, making the packaging line more convenient to use and the packaging efficiency higher.

[0025] (2) By setting an alignment mechanism, the rotating shaft can drive the fixed ring and the movable cylinder to rotate together. By setting the movable cylinder, the two sides of the battery cell can be squeezed so that the battery cell is transported in the center of the conveying device, preventing the battery cell from shifting during detection.

[0026] (3) By setting up a detection mechanism, the detection device can detect the battery cells that have passed through the detection device. When the battery cells are found to be without problems, they will move to the next step via the support shaft. If the detected battery cells are defective, the second electric push rod will drive the movable frame to move downwards, so that the guide plate is located on one side of the battery cells, allowing the battery cells in the conveying process to enter the storage box for storage. By pulling out the storage box, the defective battery cells can be collected and processed. After that, the second electric push rod will rise so that the support shaft is flush with the conveying device inside the mounting frame.

[0027] (4) The first servo motor can drive the first conveying device to transport the lowest battery cells. By setting baffles and the first spring, multiple battery cells can be prevented from slipping out during the transport process. By setting rollers, the battery cells can be transported more smoothly. Attached Figure Description

[0041] 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.

[0042] Please see Figure 1-10 This invention provides an automated battery cell packaging line, including a fifth conveying device 7 for conveying packaging boxes disposed inside a mounting frame 8. A wireless controller is installed inside the mounting frame 8. The packaging line includes:

[0043] In some embodiments, see Figure 2 , Figure 3A storage and conveying mechanism, located on one side of the mounting frame 8, is used for storing and conveying battery cells. It includes a storage bin 1, a first servo motor 101, a baffle 102, and a roller 104. The storage bin 1 is fixedly installed on one side of the sorting bin 2. The first servo motor 101 is fixedly installed on the side wall of the storage bin 1. A first conveying device 106 is fixedly installed at the output end of the first servo motor 101. The first conveying device 106 is located inside the storage bin 1. An outlet 103 corresponding to the inlet 204 is opened on one side of the storage bin 1. A first spring 105 is fixedly installed inside the storage bin 1. The baffle 102 is connected to the first spring 105. The storage box 1 is slidably connected inside the storage box 1. The baffle 102 is located inside the discharge port 103. The roller 104 is rotatably connected to one side of the baffle 102. The storage box 1 can store the battery cells that need to be packaged. The first servo motor 101 can drive the first conveying device 106 to transport the battery cells at the bottom. The baffle 102 and the first spring 105 can prevent multiple battery cells from slipping out during the conveying process. The roller 104 can make the battery cell conveying smoother.

[0044] A sorting mechanism, located between the mounting frame 8 and the material conveying mechanism, is used to sort the solar cells, allowing them to be conveyed in a regular manner. It includes a sorting bin 2, a sorting roller 202, a sorting plate 203, and a first electric push rod 208. The sorting bin 2 is fixedly installed on one side of the mounting frame 8, with a feed inlet 204 on one side. A conveying chamber 206 is formed inside the sorting bin 2, and the feed inlet 204 is located at the feed position of the conveying chamber 206. Solar cells are conveyed into the conveying chamber 206 through the feed inlet 204. The sorting roller 202 is rotatably connected inside the conveying chamber 206, and several movable cavities 207 are formed inside the sorting roller 202. The first electric push rod... The first electric push rod 208 is fixedly installed inside the movable cavity 207, and the sorting plate 203 is fixedly installed at the output end of the first electric push rod 208. The sorting plate 203 is movably connected to the movable cavity 207 through the first electric push rod 208. By setting the first electric push rod 208 to extend and retract, the sorting plate 203 can be driven to move up and down inside the sorting roller 202. Each set of movable cavities 207 is provided with a set of sorting plates 203, so that the sorting plates 203 can extend and retract synchronously with the lifting and lowering of the first electric push rod 208 at the opening position on the outer arc surface of the sorting roller 202. A mounting cavity 210 is opened on one side of the movable cavity 207, so that the mounting cavity 210 can lift and lower the sorting plate 203. The bottom of the opening of the sorting roller 202 forms a cross. A sealing plate 211 is movably connected inside the mounting cavity 210. The sealing plate 211 is movably connected inside the mounting cavity 210 by a second spring 212. By setting the second spring 212, when the sorting plate 203 is retracted into the movable cavity 207, the sealing plate 211 will pop out under the force of the second spring 212 to seal the top of the movable cavity 207, preventing the battery cell from being inserted into the movable cavity 207 and causing the sorting roller 202 to get stuck. A second servo motor 201 is fixedly installed on one side of the sorting chamber 2. The sorting roller 202 is fixedly installed on the output end of the second servo motor 201. Several rotatable connections are made inside the conveying cavity 206. The pulley shafts 205 form an inclined surface, allowing the battery cells to slide more smoothly inside the conveying chamber 206. A second servo motor 201 drives the sorting roller 202 to rotate. When the length of the battery cells to be packaged changes, the first electric push rod 208 extends or retracts the sorting plate 203, adjusting the number of protruding sorting plates 203 on the side wall of the sorting roller 202. This allows for the sorting of battery cells of different lengths without requiring replacement of the sorting device, enabling it to accommodate more battery cell specifications and making the packaging line more convenient and efficient.

[0045] In some embodiments, see Figure 3 , Figure 5 , Figure 6An arc-shaped plate 209 is fixedly installed on the top of the sorting plate 203. The bottom of the sealing plate 211 has a rounded corner that matches the arc-shaped plate 209. By setting the arc-shaped plate 209 on the top of the sorting plate 203, when the sealing plate 211 blocks the top of the movable cavity 207, if the sorting plate 203 needs to be raised, the arc-shaped plate 209 on the top of the sorting plate 203 can be used in conjunction with the rounded corner at the bottom of the sealing plate 211 to push the sealing plate 211 into the installation cavity 210, so that the sorting plate 203 can extend out.

[0046] In some embodiments, see Figure 1 , Figure 6 The mounting frame 8 is equipped with a second conveying device 213. The second conveying device 213 has a groove 214 that matches the sorting plate 203. By setting the groove 214, the battery cells conveyed by the sorting device can be conveyed, and the second conveying device 213 can reciprocate along the extension direction of the groove 214.

[0047] See Figure 7 , Figure 8 An alignment mechanism, located inside the mounting frame 8, is used to center the battery cells during the cell transport process. It includes a fixed plate 3, a third servo motor 301, a rotating shaft 302, a fixed ring 303, and a movable cylinder 305. The fixed plate 3 is fixedly mounted on the inner wall of the mounting frame 8. The third servo motor 301 is fixedly mounted on the top of the fixed plate 3. The rotating shaft 302 is fixedly mounted on the output end of the third servo motor 301 and rotatably connected to the bottom of the fixed plate 3. The fixed ring 303 is fixedly mounted on the side wall of the rotating shaft 302, and a third spring 304 is fixedly mounted on the side wall of the fixed ring 303. The movable cylinder 305 is fixedly mounted on one end of the third spring 304. The third servo motor 301 drives the rotating shaft 302 to rotate, which in turn drives the fixed ring 303 and the movable cylinder 305 to rotate together. The movable cylinder 305 can squeeze the sides of the battery cells, thus centering them in the transport device and preventing them from shifting during inspection.

[0048] See Figure 7 , Figure 9The inspection mechanism, located at the top of the mounting frame 8, is used to inspect the solar cells and centrally store defective solar cells. It includes an inspection device 4, a movable frame 5, a support shaft 502, a fixed frame 503, and a guide plate 506. A third conveying device 401 is installed inside the mounting frame 8. The inspection device 4 is fixedly installed on the top of the mounting frame 8, which is located on top of the third conveying device 401. A second electric push rod 501 is fixedly installed inside the mounting frame 8. The movable frame 5 is fixedly installed on top of the second electric push rod 501 and is located on one side of the third conveying device 401. The support shaft 502 is rotatably connected inside the movable frame 5. The fixed frame 503 is fixedly installed inside the movable frame 5, and a movable column 504 is slidably connected inside the fixed frame 503. The guide plate 506 is fixedly installed at one end of the movable column 504, and its top is connected to... A fourth spring 505 is directly fixedly installed at the bottom of the fixed frame 503. The fourth spring 505 is located on the side wall of the movable column 504. A storage box 507 is slidably connected inside the mounting frame 8. The storage box 507 is located on one side of the movable frame 5. The battery cells that have passed through the detection device 4 can be detected by setting a detection device 4. When the battery cell is found to be without problems, it will move to the next step via the support shaft 502. If the detected battery cell is defective, the second electric push rod 501 will drive the movable frame 5 to move downward, so that the guide plate 506 is located on one side of the battery cell, so that the battery cell in the process of conveying can enter the storage box 507 for storage. By pulling out the storage box 507, the defective battery cells can be collected and processed. After that, the second electric push rod 501 will rise so that the support shaft 502 is flush with the conveying device inside the mounting frame 8.

[0049] In some embodiments, see Figure 7 , Figure 10The mounting mechanism, located inside the mounting frame 8, is used to place the tested battery cells inside the packaging box. It includes a fourth conveying device 6, a roller 601, a fourth servo motor 602, a third electric push rod 604, a pressure plate 605, and a pressure sensor 606. The fourth conveying device 6 is installed inside the mounting frame 8 and is located on one side of the movable frame 5. The fourth servo motor 602 is fixedly installed on one side of the mounting frame 8. The roller 601 is fixedly installed at the output end of the fourth servo motor 602 and is rotatably connected inside the mounting frame 8. The roller 601 has several clamping slots 603 inside. The third electric push rod 604 is fixedly installed inside the roller 601, and its output end is located in one of the clamping slots 603. Inside, a pressure plate 605 is fixedly installed at the output end of the third electric push rod 604, and a pressure sensor 606 is fixedly installed inside the clamping groove 603. Several pressure sensors 606 are provided. The roller 601 is located at the top of the fifth conveying device 7. When the battery cell is conveyed to the clamping groove 603 inside the roller 601 through the fourth conveying device 6, the battery cell will come into contact with the pressure sensor 606. At this time, the third electric push rod 604 extends and drives the pressure plate 605 at the output end to clamp the battery cell. Then, the fourth servo motor 602 drives the roller 601 to rotate, so that the battery cell is located on the top of the packaging box conveyed by the fifth conveying device 7. Then, the third electric push rod 604 retracts, so that the battery cell falls into the packaging box, completing the packaging of the battery cell.

[0050] like Figure 1 and Figure 7 As shown, a drive device 9 is fixedly mounted on the side wall of the mounting bracket 8. The output end of the drive device 9 is connected to the second conveying device 213, the third conveying device 401, and the fourth conveying device 6 respectively, and serves as the drive output. The drive device 9 is a drive mechanism with a transmission mechanism, and its connecting end is connected to the second conveying device 213, the third conveying device 401, and the fourth conveying device 6 respectively. These description methods can be flexibly applied according to specific needs.

[0051] In this embodiment, the first servo motor 101, the second servo motor 201, the third servo motor 301, the fourth servo motor 602, the first conveying device 106, the second conveying device 213, the third conveying device 401, the fourth conveying device 6, the fifth conveying device 7, the first electric push rod 208, the second electric push rod 501, the third electric push rod 604, and the wireless controller involved can be freely configured according to actual application scenarios. The wireless controller controls the operation of the first servo motor 101, the second servo motor 201, the third servo motor 301, the fourth servo motor 602, the first conveying device 106, the second conveying device 213, the third conveying device 401, the fourth conveying device 6, the first electric push rod 208, the second electric push rod 501, and the third electric push rod 604 using methods commonly used in the prior art.

[0052] The working process and principle of the present invention: When in use, the battery cells to be packaged are placed inside the storage box 1. The first servo motor 101 drives the first conveying device 106 to move, thereby conveying the battery cells at the bottom. By setting baffle 102 and first spring 105, multiple battery cells can be prevented from slipping out during the conveying process. By setting roller 104, the conveying of battery cells can be made smoother.

[0053] The battery cells then enter the sorting chamber 2. By setting the pulley shaft 205, the battery cells can slide more smoothly inside the conveying chamber 206. By setting the second servo motor 201, the operation of the second servo motor 201 can drive the sorting roller 202 to rotate, thereby driving the sorting plate 203 to rotate and sort the battery cells. By setting the groove 214, the battery cells conveyed by the sorting device can be transported.

[0054] The detection device 4 can be used to inspect the battery cells that have passed through it. If the battery cell passes inspection without issues, it will move to the next step via the support shaft 502. If a defective battery cell is detected, the second electric push rod 501 will move the movable frame 5 downwards, positioning the guide plate 506 on one side of the battery cell. This allows the battery cells to enter the storage box 507 for storage. By pulling out the storage box 507, defective battery cells can be collected and processed. Afterwards, the second electric push rod 501 will rise to support the battery cell. The support shaft 502 is flush with the conveying device inside the mounting frame 8. When the battery cell is conveyed to the clamping groove 603 inside the roller 601 by the fourth conveying device 6, the battery cell will come into contact with the pressure sensor 606. At this time, the third electric push rod 604 extends and drives the pressure plate 605 at the output end to clamp the battery cell. Then, the fourth servo motor 602 drives the roller 601 to rotate, so that the battery cell is located on top of the packaging box conveyed by the fifth conveying device 7. Then, the third electric push rod 604 retracts, so that the battery cell falls into the packaging box, completing the packaging of the battery cell.

[0055] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
