In the whole flow transfer process of the battery piece, after the first carrier or the second carrier completes the loading of the previous batch of battery pieces, the first carrier or the second carrier is backflowed through the transfer device, the conveying device and the feeding device or through the transfer device and the discharging device, and the backflowed first carrier or second carrier can start to participate in the loading of the next batch of battery pieces. In this way, the first carrier or the second carrier does not need to participate in the whole flow transfer process of a single batch of battery pieces, the operation time and the transfer time of the battery pieces between process steps are reduced, and the production efficiency is improved.

Description

Technical Field

[0001] This application relates to the field of battery cell processing technology, and in particular to a battery cell passivation process system. Background Technology

[0002] In the production of solar cells, to improve the electrical performance of the structure and reduce costs while increasing efficiency, it is usually necessary to dicing and cutting the sheet material into multiple pieces, and then performing ALD (Atomic Layer Deposition) passivation coating on the cut surfaces of the sheet material. The ALD passivation process can form a passivation film on the cut surfaces of the sheet material through deposition, thereby improving the quality and efficiency of the cell surface and reducing carrier corrosion problems.

[0003] In related technologies, the passivation process of solar cells involves multiple processing steps, and the solar cells need to be transferred in an orderly manner between each processing step. However, due to unreasonable equipment layout and excessively long transfer length in the solar cell passivation process system, there may be instances where solar cells stay for a long time in certain processing steps, which increases the overall production cycle and production cost, and affects production efficiency. Summary of the Invention

[0004] In view of the above, it is necessary to provide a cell passivation process system that can improve production efficiency.

[0005] This application provides a passivation process system for solar cells, including a loading device, a transport device, a boat placement platform, a boat transfer device, a processing device, a transport device, a transfer device, and a unloading device. The loading device is used to load unprocessed solar cells into an empty first carrier. The transport device is used to transport the first carrier loaded with unprocessed solar cells from the loading device to a process boat located on the boat placement platform. The boat transfer device is used to transfer the process boat loaded with the first carrier between the boat placement platform and the processing device. The transport device is also used to transport the first carrier loaded with processed solar cells from the process boat located on the boat placement platform to a transfer device. The transfer device is used to transport the processed solar cells from the first carrier to a second carrier. The transport device is also used to transport the empty first carrier from the transfer device to the loading device. The transfer device is used to transport the second carrier loaded with processed solar cells from the transfer device to the unloading device. The unloading device is used to remove the processed solar cells from the second carrier. The transfer device is also used to transport the empty second carrier from the unloading device to the transfer device.

[0006] The cell passivation process system provided in this application allows for the return of the first or second carrier after loading the previous batch of cells into the cell circulation process. This is achieved through a transfer device, a handling device, and a loading device, or through a transfer device and a unloading device. The returned first or second carrier can then participate in loading the next batch of cells. This eliminates the need for the first or second carrier to participate in the entire circulation process of a single batch of cells, reducing operation time and the transfer time between process steps, thus improving production efficiency.

[0019] like Figures 1 to 4 As shown, the cell passivation process system is used to achieve automatic loading and unloading of materials and automated processing. In the example of this application, the processing technology of the cell passivation process system can be ALD (Atomic Layer Deposition). The material can be a cell 10, which is sheet-shaped and can also be called sheet material. In the material transportation scenario, the cell 10 can be loaded in a carrier, which carries, limits, and protects the cell 10. In the embodiments of this application, the carrier is exemplified by a first carrier 20 and a second carrier 30. In the material processing scenario, the first carrier 20 can be loaded in a process boat 40, which is used to enter the process environment to perform passivation processing on the cell 10 in the first carrier 20.

[0020] In the example of this application, the cell passivation process system includes a feeding device 100, a handling device 200, a boat placement platform 300, a boat moving device 400, a processing device 500, a transfer device 700, a circulation device 800, and a unloading device 900.

[0021] The solar cell passivation process system has a loading transfer area, a process transfer area, and an unloading transfer area, with the process transfer area located between the loading and unloading transfer areas. A loading device 100, a handling device 200, a boat placement platform 300, and a transfer device 700 are located in the loading transfer area. A processing device 500 is located in the process transfer area. An unloading device 900 is located in the unloading transfer area. A transfer device 800 spans the loading, process, and unloading transfer areas, and a boat handling device 400 spans the loading and process transfer areas.

[0022] The loading device 100 is used to load unprocessed solar cells 10 into an empty first carrier 20. Specifically, the loading device 100 can store the first carrier 20, which can be an empty first carrier 20 or a fully loaded first carrier 20 containing unprocessed solar cells 10. It can be understood that an empty first carrier 20 refers to a first carrier 20 that is not loaded with solar cells 10, and a fully loaded first carrier 20 refers to a first carrier 20 that is loaded with a specified number of unprocessed solar cells 10.

[0023] The feeding device 100 is capable of receiving unprocessed solar cells 10 from the upstream processing equipment, and then loading the unprocessed solar cells 10 into an empty first carrier 20, thereby obtaining a fully loaded first carrier 20 of unprocessed solar cells 10. The upstream processing equipment can be a conveyor line that transports solar cells 10 that need to be processed.

[0024] The boat placement platform 300 is used to store the process boats 40. Specifically, the process boats 40 stored on the boat placement platform 300 can be empty, fully loaded with unprocessed process boats 40, or fully loaded with processed process boats 40. It can be understood that an empty process boat 40 refers to a process boat 40 that is not loaded with the first carrier 20, a fully loaded unprocessed process boat 40 refers to a process boat 40 loaded with unprocessed first carriers 20, and a fully loaded processed process boat 40 refers to a process boat 40 loaded with a specified number of processed first carriers 20. A processed first carrier 20 refers to a first carrier 20 loaded with a specified number of processed battery cells 10.

[0025] The transport device 200 is used to transfer the first carrier 20 between the boat placement platform 300 and the loading device 100. Specifically, the transport device 200 is capable of transporting the first carrier 20 loaded with unprocessed battery cells 10 from the loading device 100 to the process boat 40 stored on the boat placement platform 300. It can be understood that the transport device 200 is capable of loading the unprocessed first carrier 20 onto the process boat 40, and after the process boat 40 is loaded with a specified number of unprocessed first carriers 20, the boat placement platform 300 can obtain a fully loaded unprocessed process boat 40.

[0026] The processing device 500 is used to passivate the battery cells 10 in the process boat 40.

[0027] The boat-moving device 400 is used to transfer the process boat 40 loaded with the first carrier 20 between the boat placement platform 300 and the processing device 500. Specifically, the boat-moving device 400 can transport a fully loaded, unprocessed process boat 40 to the processing device 500 for passivation processing. It can be understood that after the process boat 40 has completed processing, the boat-moving device 400 can obtain a fully loaded, processed process boat 40, in which the processed first carrier 20 is loaded.

[0028] The handling device 200 is also capable of transporting the first carrier 20 loaded with processed battery cells 10 from the process boat 40 located on the boat placement platform 300 to the transfer device 700. It can be understood that after the first carrier 20 in the fully loaded processed process boat 40 is removed, the boat placement platform 300 can obtain a fully loaded unprocessed process boat 40.

[0029] The conveying device 200 can also transport the empty first carrier 20 from the transfer device 700 to the loading device 100. In this way, the empty first carrier 20 is returned from the transfer device 700 to the loading device 100, and the loading device 100 can obtain the empty first carrier 20.

[0030] The transfer device 700 can store the first carrier 20 and the second carrier 30. The second carrier 30 and the first carrier 20 are different carriers, belonging to two separate independent entities, and can independently complete the loading and transport of the battery cells 10. It is worth noting that the first carrier 20 and the second carrier 30 can be different types of carriers, or they can be the same type of carrier.

[0031] The first carrier 20 stored in the transfer device 700 can be an empty first carrier 20 or a fully loaded processed first carrier 20.

[0032] The second carrier 30 stored in the transfer device 700 can be an empty second carrier 30 or a fully loaded processed second carrier 30. It can be understood that an empty second carrier 30 refers to a second carrier 30 that is not loaded with battery cells 10, and a fully loaded processed second carrier 30 refers to a second carrier 30 loaded with a specified number of processed battery cells 10.

[0033] The transfer device 700 is used to transfer the battery cells 10 between the first carrier 20 and the second carrier 30. Specifically, the transfer device 700 is capable of transporting the processed battery cells 10 from the first carrier 20 to the second carrier 30. It can be understood that after the fully loaded processed battery cells 10 in the first carrier 20 are removed, the transfer device 700 can obtain an empty first carrier 20, and after the processed battery cells 10 are transported to the second carrier 30, the transfer device 700 can obtain a fully loaded processed second carrier 30.

[0034] The transfer device 800 is used to transfer the second carrier 30 between the transfer device 700 and the unloading device 900. Specifically, the transfer device 800 is capable of transporting the second carrier 30 loaded with the processed battery cells 10 from the transfer device 700 to the unloading device 900.

[0035] The transfer device 800 can also transport the empty second carrier 30 from the unloading device 900 to the transfer device 700. In this way, the empty second carrier 30 is returned from the unloading device 900 to the transfer device 700, and the transfer device 700 can obtain the empty second carrier 30.

[0036] The unloading device 900 is used to remove the processed solar cells 10 from the second carrier 30 and to provide the empty second carrier 30 to the transfer device 800. Specifically, after the processed solar cells 10 are removed from the second carrier 30, the processed solar cells 10 can proceed to the next process, and after the fully loaded processed solar cells 10 in the second carrier 30 are removed, the unloading device 900 can obtain an empty second carrier 30.

[0037] For ease of understanding, the flow process of the solar cell 10 will be described as an example below. The flow process of the solar cell 10 includes the following steps.

[0038] S1. The feeding device 100 loads the unprocessed battery cells 10 into the empty first carrier 20.

[0039] S2. The transport device 200 transports the first carrier 20 from the loading device 100 to the empty process boat 40 of the boat placement platform 300.

[0040] S3, the boat-moving device 400 puts the process boat 40 into the processing device 500.

[0041] S4. After the processing is completed, the boat moving device 400 moves the process boat 40 to the boat placement platform 300.

[0042] S5. The handling device 200 removes the first carrier 20 from the process boat 40 of the boat placement platform 300 and transports it to the transfer device 700.

[0043] S6. The transfer device 700 removes the battery cell 10 from the first carrier 20 and transfers it to the empty second carrier 30.

[0044] S7. Transfer device 800 moves the second carrier 30 from transfer device 700 to unloading device 900.

[0045] S8. The unloading device 900 removes the processed battery cell 10 from the second carrier 30.

[0046] In step S5, the boat placement platform 300 can obtain an empty process boat 40 again, realizing the return flow of the process boat 40.

[0047] After step S6, the transfer device 700 can obtain an empty first carrier 20, and can execute step S01: the handling device 200 transports the empty first carrier 20 to the loading device 100. In this way, the loading device 100 can obtain an empty first carrier 20 again, realizing the return flow of the first carrier 20.

[0048] After step S8, the unloading device 900 obtains an empty second carrier 30, and step S02 can be executed: the transfer device 800 transports the empty second carrier 30 to the transfer device 700. The transfer device 700 can obtain an empty second carrier 30 again, realizing the return flow of the second carrier 30.

[0049] In the example of this application, the first carrier 20 and the second carrier 30 can be different types of material boxes. The differences between the two material boxes include at least the following: the first carrier 20 has a relatively strong limiting effect on the battery cell 10, while the second carrier 30 has a relatively weak limiting effect on the battery cell 10.

[0050] For example, the first carrier 20 and the second carrier 30 each have an inner cavity for accommodating the battery cell 10, and a limiting structure for limiting the battery cell 10 is provided in the inner cavity.

[0051] The inner cavity of the first carrier 20 is better suited to the stacked volume of the battery cells 10, resulting in a smaller gap between the inner side of the first carrier 20 and the periphery of the battery cells 10. Furthermore, the limiting structure employs a structure with relatively high mechanical strength. When the battery cells 10 are loaded onto the first carrier 20, they are less prone to displacement or have minimal displacement space during the transfer process, exhibiting strong positioning performance. This makes them suitable for process steps requiring high positioning accuracy for the battery cells 10.

[0052] That is, in steps S1 to S5, that is, before and during the processing of the battery cell 10, the battery cell 10 can be accurately positioned, ensuring the stability and precise control of process parameters, reducing product quality problems caused by human factors and equipment fluctuations, and improving the consistency and stability of product quality.

[0053] The inner cavity of the second carrier 30 is relatively spacious relative to the stacked volume of the battery cells 10, allowing for a larger gap between the inner side of the second carrier 30 and the periphery of the battery cells 10. Furthermore, the limiting structure employs a relatively low mechanical strength or an elastic structure. When the battery cells 10 are mounted on the second carrier 30, they are relatively easy to shift or have a large shift space during transport, thus providing a buffering effect. This design is suitable for process steps where the safety requirements of the battery cells 10 are high.

[0054] That is, during steps S6 to S8, after the battery cell 10 has been processed, the requirements for the positioning accuracy of the battery cell 10 can be appropriately relaxed to reduce the probability of the battery cell 10 breaking during subsequent transportation.

[0055] Thus, by using the first carrier 20 for loading the battery cell 10 from unprocessed to finished, and by using the second carrier 30 for loading the battery cell 10 from finished to unloaded, different carriers can be configured to meet the needs of different process stages, thereby satisfying different production requirements and improving the overall production efficiency of the production line while meeting the processing quality conditions of the battery cell 10.

[0056] It is worth noting that the types of the first carrier 20 and the second carrier 30 mentioned above are merely illustrative examples. In practical applications, the types of carriers can be configured according to the needs of the process, and the loading method of the battery cells 10 can also be adapted according to the types of carriers. This application does not impose any restrictions on this.

[0057] It is understandable that during the entire flow of the solar cells 10, after the first carrier 20 completes loading the previous batch of solar cells 10 from unprocessed to processed, it is returned to its original location via the transfer device 700, the handling device 200, and the loading device 100. After returning, the first carrier 20 can then participate in loading the next batch of solar cells 10 from unprocessed to processed. In this way, the first carrier 20 does not need to participate in the entire flow of a single batch of solar cells 10, shortening the waiting time between loading the previous and next batches of solar cells 10, reducing operation time and the transfer time of the solar cells 10 between various process steps, and improving production efficiency.

[0058] Similarly, after the second carrier 30 completes the loading of the previous batch of solar cells 10 from processing to unloading, the second carrier 30 is returned via the transfer device 700 and the unloading device 900. The returned second carrier 30 can then participate in the loading of the next batch of solar cells 10 from processing to unloading. In this way, the second carrier 30 does not need to participate in the entire flow process of a single batch of solar cells 10, shortening the waiting time between loading the previous and next batches of solar cells 10, reducing operation time and the transfer time of solar cells 10 between various process steps, and improving production efficiency.

[0059] In some embodiments, the cell passivation process system further includes a boat cooling platform 1000, which is disposed in the process flow area and located on one side of the processing apparatus 500.

[0060] The boat cooling platform 1000 is used to store the process boats 40. Specifically, the process boats 40 stored in the boat cooling platform 1000 can be either fully loaded with unprocessed process boats 40 or fully loaded with processed process boats 40.

[0061] The boat-moving device 400 is also used to transfer the process boat 40 between the boat placement platform 300, the boat cooling platform 1000, and the processing device 500. Specifically, before the process boat 40 is put into the processing device 500 for processing, the boat-moving device 400 can move the process boat 40 to the boat cooling platform 1000 for transfer and waiting. After the corresponding conditions are met, the boat-moving device 400 then moves the process boat 40 to the processing device 500. In this way, the space occupied by the process boat 40 on the boat placement platform 300 can be reduced, facilitating the movement of the first carrier 20.

[0062] After the process boat 40 completes processing in the processing device 500, the boat-moving device 400 can transport the process boat 40 to the boat cooling platform 1000 for cooling. After cooling, the boat-moving device 400 then transports the process boat 40 to the boat placement platform 300. Since the process boat 40 needs to be in a high-temperature environment during processing, the boat cooling platform 1000 can reduce the impact of the high temperature of the process boat 40 on the devices or battery cells 10 in the upstream transfer area.

[0063] In some embodiments, the transfer device 800 includes a loading transfer mechanism 1100, a unloading transfer mechanism 1200, and a transition transfer mechanism 1300. The loading transfer mechanism 1100 extends along a first direction and is used to transport the second carrier 30 along the first direction. The unloading transfer mechanism 1200 extends along the first direction and is spaced apart from the loading transfer mechanism 1100 along a second direction. The unloading transfer mechanism 1200 is used to transport the second carrier 30 along the first direction, and there is an angle between the first and second directions. The transition transfer mechanism 1300 is disposed between the loading transfer mechanism 1100 and the unloading transfer mechanism 1200 and is used to transport the second carrier 30 along the second direction. Exemplarily, the first direction is the X-axis direction shown in the figure, and the second direction is the Y-axis direction shown in the figure.

[0064] In the example of this application, a process transfer area is formed between the loading transfer mechanism 1100, the unloading transfer mechanism 1200, and the transition transfer mechanism 1300. The loading transfer area is formed on the side of the loading transfer mechanism 1100 away from the process transfer area, and the unloading transfer area is formed on the side of the unloading transfer mechanism 1200 away from the process transfer area. Thus, the loading transfer area, the process transfer area, and the unloading transfer area are distributed sequentially along the second direction.

[0065] When it is necessary to transport the second carrier 30 from the transfer device 700 to the unloading device 900, firstly, the loading transfer mechanism 1100 obtains the second carrier 30 from the transfer device 700 and transports the second carrier 30 to the transition transfer mechanism 1300 along the first direction; then, the transition transfer mechanism 1300 transports the second carrier 30 to the unloading transfer mechanism 1200 along the second direction; then, the unloading transfer mechanism 1200 transports the second carrier 30 to the unloading device 900 along the first direction.

[0066] When it is necessary to transfer the second carrier 30 from the unloading device 900 to the transfer device 700, firstly, the unloading transfer mechanism 1200 obtains the second carrier 30 from the unloading device 900 and transfers the second carrier 30 to the transition transfer mechanism 1300 along the first direction; then, the transition transfer mechanism 1300 transfers the second carrier 30 to the loading transfer mechanism 1100 along the second direction; then, the loading transfer mechanism 1100 transfers the second carrier 30 to the transfer device 700 along the first direction.

[0067] Figure 5 This is a schematic diagram of the layout of the material loading and transfer area provided in this application.

[0068] Please refer to the following: Figure 5 In some embodiments, the loading device 100, the transfer device 700, the handling device 200, and the boat placement platform 300 constitute a loading unit. Within the same loading unit, the loading device 100, transfer device 700, and boat placement platform 300 are distributed at intervals around the handling device 200. This shortens the distance between the handling device 200 and the loading device 100, transfer device 700, and boat placement platform 300, improving the turnover efficiency of the first carrier 20.

[0069] Specifically, the feeding unit comprises multiple sets, which are spaced apart along a first direction. Multiple transfer devices 700 within the multiple feeding units are all located on one side of the feeding transfer mechanism 1100 and are spaced apart along the first direction. Thus, the feeding transfer mechanism 1100 can acquire the first carrier 20 of each of the multiple transfer devices 700 along the first direction, or provide the first carrier 20 to each of the multiple transfer devices 700 along the first direction.

[0070] For example, there are two feeding units, arranged side-by-side in the feeding transfer area along a first direction. Each feeding unit includes two feeding devices 100, one transfer device 700, one handling device 200, and one boat placement platform 300. The handling device 200 is located on the side of the feeding transfer area closest to the feeding transfer mechanism 1100. The boat placement platform 300 is located on the side of the handling device 200 closest to the center of the feeding transfer area. The transfer device 700 is located on the side of the handling device 200 away from the boat placement platform 300. The two feeding devices 100 are spaced apart along the first direction, and both feeding devices 100 are located on the side of the handling device 200 away from the feeding transfer mechanism 1100.

[0071] It is understood that each feeding unit is constructed around the handling device 200, enabling the handling device 200 to acquire or place the first carrier 20 from other surrounding devices. In this way, multiple feeding units can simultaneously transfer the battery cells 10 and the first carrier 20, improving production efficiency. Furthermore, the optimized arrangement of each feeding unit improves the equipment layout, making the positions of related devices more compact, shortening the transfer distance between devices, and reducing the equipment's footprint.

[0072] It is worth noting that in other embodiments, the type or number of devices in each feeding unit can be adjusted according to actual needs, as long as the flow of the battery cell 10 and the first carrier 20 can be met. This application does not impose any restrictions on this.

[0073] In some embodiments, the feeding device 100 includes a feeding conveyor line 101, a wafer picking and placing mechanism 102, and a carrier positioning mechanism 103. The feeding conveyor line 101 is used to transport unprocessed battery cells 10. The carrier positioning mechanism 103 is used to place a first carrier 20. The wafer picking and placing mechanism 102 is disposed between the feeding conveyor line 101 and the carrier positioning mechanism 103, and is used to pick up battery cells 10 from the feeding conveyor line 101 and transport them to the first carrier 20 of the carrier positioning mechanism 103.

[0074] In the example of this application, the battery cells 10 are loaded onto the first carrier 20 by stacking, that is, multiple battery cells 10 can be stacked vertically within the first carrier 20. In other embodiments, the battery cells 10 can also be loaded into the first carrier 20 in other ways, specifically according to the shape and material of the battery cells 10, or according to the type of carrier.

[0075] For example, the loading conveyor line 101 is a conveyor belt mechanism. The solar cells 10 conveyed by the upstream process equipment can be transported to the loading conveyor line 101 individually or in stacks, and then transported by the loading conveyor line 101 to a designated position for the cell pick-and-place mechanism 102 to pick up the solar cells 10.

[0076] For example, the pick-and-place mechanism 102 includes a pick-and-place component and a pick-and-place drive component, with the drive component connected to the pick-and-place component. The pick-and-place component grips the battery cell 10, and the drive component moves the pick-and-place component to a designated position to grip the battery cell 10, or places the gripped battery cell 10 at a designated position. The drive component can be a multi-axis robotic arm, with the pick-and-place component located at the movable end of the multi-axis robotic arm, enabling high-precision displacement of the pick-and-place component. The pick-and-place component can be a suction cup or gripper, or other structure suitable for picking up and placing the battery cell 10, and can be configured according to the shape and material of the battery cell 10, or according to the type of carrier.

[0077] For example, the carrier positioning mechanism 103 is also used to position the first carrier 20 so that the first carrier 20 is less likely to deviate in position when loading the battery cells 10, thereby improving the accuracy of the stacking of the battery cells 10.

[0078] For example, the carrier positioning mechanism 103 is provided with a first positioning area and a second positioning area. The first positioning area is used to place the first carrier 20, and the second positioning area is used to place the waste carrier. The waste carrier is used to load waste cells that do not participate in subsequent processing stages; the waste cells can be defective or have substandard parameters. If there are waste cells among the battery cells 10 being conveyed by the feeding conveyor line 101, the cell picking and placing mechanism 102 picks up the waste cells from the feeding conveyor line 101 and transports them to the waste carrier of the carrier positioning mechanism 103 for recycling.

[0079] In some embodiments, the handling device 200 includes a carrier placement platform 201, a handling gripping mechanism 202, and a handling drive mechanism 203. The carrier placement platform 201 is disposed between the loading device 100, the boat placement platform 300, and the transfer device 700, and is used to place a first carrier 20. The handling gripping mechanism 202 is used to grip the first carrier 20. The handling drive mechanism 203 is connected to the handling gripping mechanism 202. The handling drive mechanism 203 is used to drive the handling gripping mechanism 202 to move, thereby transferring the first carrier 20 between the loading device 100, the boat placement platform 300, and the transfer device 700.

[0080] For example, the handling and gripping mechanism 202 can be a gripper mechanism, which is suitable for gripping the first carrier 20. The handling drive mechanism 203 can be a multi-axis robotic arm, and the handling and gripping mechanism 202 is located at the active end of the multi-axis robotic arm, and the active range of the multi-axis robotic arm spans the area where the loading device 100, the boat placement platform 300 and the transfer device 700 are located.

[0081] During the process of the conveying device 200 moving the first carrier 20 from the loading device 100 to the empty process boat 40 of the boat placement platform 300, the actions of the conveying device 200 may include: first, the conveying drive mechanism 203 drives the conveying gripping mechanism 202 to move to the carrier positioning mechanism 103, and the conveying gripping mechanism 202 grips the first carrier 20 in the carrier positioning mechanism 103; then, the conveying drive mechanism 203 drives the conveying gripping mechanism 202 to move to the boat placement platform 300, and drives the conveying gripping mechanism 202 to insert the first carrier 20 into the process boat 40 in the boat placement platform 300.

[0082] During the process of the handling device 200 removing the first carrier 20 from the process boat 40 of the boat placement platform 300 and transporting it to the transfer device 700, the actions of the handling device 200 may include: first, the handling drive mechanism 203 drives the handling gripping mechanism 202 to move to the boat placement platform 300, and the handling gripping mechanism 202 grips the first carrier 20 in the process boat 40 of the boat placement platform 300; then, the handling drive mechanism 203 drives the handling gripping mechanism 202 to move to the transfer device 700, and the handling gripping mechanism 202 places the first carrier 20 in the transfer device 700.

[0083] It is understood that during the process of transferring the first carrier 20 between the loading device 100, the boat placement platform 300 and the transfer device 700, the operation of the handling device 200 can be adjusted according to the process requirements. For example, the handling device 200 can also be used to put on and take off the cover of the first carrier 20. This application does not limit this.

[0084] In some embodiments, the transfer device 700 includes a separation mechanism 701, a carrier buffer mechanism 702, and a transfer conveying mechanism 703. The separation mechanism 701 is disposed on one side of the handling device 200 and is used to place the first carrier 20 and separate the processed battery cell 10 from the first carrier 20. The carrier buffer mechanism 702 is disposed on one side of the transfer device 800 and is used to place the second carrier 30. The transfer conveying mechanism 703 is connected to the carrier buffer mechanism 702 and the separation mechanism 701, and is used to transport the separated battery cell 10 from the separation mechanism 701 to the second carrier 30 located in the carrier buffer mechanism 702.

[0085] For example, the separation mechanism 701 is a lifting structure. When the first carrier 20 loaded with battery cells 10 is placed on the separation mechanism 701, the separation mechanism 701 can lift the battery cells 10 out of the first carrier 20 so that the transfer and conveying mechanism 703 can take them away.

[0086] Specifically, the inner cavity of the first carrier 20 extends through its top to form an opening, and the bottom of the first carrier 20 has an opening. The area of ​​the cavity opening of the first carrier 20 is larger than the area of ​​the battery cell 10, and the area of ​​the opening of the first carrier 20 is smaller than the area of ​​the cavity opening. Thus, the battery cell 10 can enter and exit the inner cavity through the cavity opening of the first carrier 20, the opening of the first carrier 20 allows the separation mechanism 701 to extend into the bottom of the inner cavity, and the battery cell 10 cannot be completely detached from the inner cavity through the opening of the first carrier 20.

[0087] The separation mechanism 701 includes a placement platform, a lifting member, and a lifting drive member. The lifting member is disposed on the placement platform, and its position corresponds to the opening of the first carrier 20. The lifting drive member is connected to the lifting member and is used to drive the lifting member to move up and down relative to the placement platform.

[0088] When it is necessary to separate the processed battery cell 10 from the first carrier 20, firstly, the lifting member is lowered to or maintained at a lower height; then, the first carrier 20 is placed on the placement platform, aligning the opening of the first carrier 20 with the lifting member; then, the lifting drive member drives the lifting member to rise to a higher height. During the rising process of the lifting member, the lifting member lifts the battery cell 10 and exposes it from the cavity of the first carrier 20 to the top of the first carrier 20, thereby achieving the separation of the battery cell 10 from the first carrier 20.

[0089] It is worth noting that the separation mechanism 701 in this embodiment uses a lifting method to separate the battery cell 10 from the first carrier 20. In other embodiments, the separation mechanism 701 can also use other methods, such as using a gripper structure to extend into the first carrier 20 to grab the battery cell 10. The specific configuration can be based on the shape, material, stacking method of the battery cell 10, or the type of carrier. This application does not limit this.

[0090] For example, the transfer and conveying mechanism 703 includes a cell-grabbing component and a transfer drive component. The cell-grabbing component is used to grip the battery cell 10, and the transfer drive component is connected to the cell-grabbing component. The transfer drive component is used to drive the cell-grabbing component to move to a designated position to grip the battery cell 10, or to place the gripped battery cell 10 at a designated position. The transfer drive component can be a gantry-type three-dimensional translation mechanism, which can drive the cell-grabbing component to move back and forth in the horizontal and vertical directions, wherein the horizontal direction includes a first direction and a second direction. The cell-grabbing component can be a gripper or other structure suitable for picking up and placing the battery cell 10, and can be configured according to the shape and material of the battery cell 10, or according to the type of carrier.

[0091] After the battery cell 10 has been separated from the first carrier 20, the transfer drive causes the cell picking member to move to the separation mechanism 701, where the cell picking member picks up the separated battery cell 10. Then, the transfer drive causes the cell picking member to move to the carrier buffer mechanism 702 and causes the cell picking member to insert the battery cell 10 into the second carrier 30 located in the carrier buffer mechanism 702, thereby realizing the transfer of the battery cell 10 from the first carrier 20 to the second carrier 30.

[0092] In some embodiments, the boat cooling platform 1000 is disposed on the side of the loading and transfer mechanism 1100 away from the boat placement platform 300, and the boat placement platform 300 and the boat cooling platform 1000 are sequentially distributed in the second direction. In this way, the distance between the boat cooling platform 1000 and the boat placement platform 300 can be shortened, and the boat handling device 400 can directly transfer the process boat 40 between the boat placement platform 300 and the boat cooling platform 1000 along the second direction.

[0093] Multiple boat cooling platforms 1000 are distributed at intervals along a first direction. Thus, multiple boat cooling platforms 1000 respectively hold multiple process boats 40, facilitating the transfer and cooling of the process boats 40. A boat-moving device 400 is capable of transporting the process boats 40 from the multiple boat cooling platforms 1000 along the first direction. For example, the number of boat cooling platforms 1000 is four, and the four boat cooling platforms 1000 are arranged side-by-side along the first direction.

[0094] It is worth noting that in other embodiments, the number of boat cooling platforms 1000 can also be adjusted according to actual needs, as long as the flow of the process boat 40 can be met, and this application does not impose any restrictions on this.

[0095] In some embodiments, the processing apparatus 500 is an ALD passivation process host. The processing apparatus 500 is disposed on the side of the boat cooling platform 1000 away from the loading and transfer mechanism 1100, and the boat placement platform 300, the boat cooling platform 1000, and the processing apparatus 500 are sequentially distributed in the second direction. In this way, the distance between the boat cooling platform 1000 and the processing apparatus 500 can be shortened, and the boat handling device 400 can directly transfer the process boat 40 between the boat cooling platform 1000 and the processing apparatus 500 along the second direction.

[0096] In some embodiments, the boat handling device 400 includes a boat gripping mechanism 401 and a boat handling drive mechanism 402. The boat gripping mechanism 401 grips the process boat 40. The boat handling drive mechanism 402 is connected to the boat gripping mechanism 401. The boat handling drive mechanism 402 drives the boat gripping mechanism 401 to move, thereby transferring the process boat 40 between the loading transfer area and the process transfer area.

[0097] For example, the boat gripping mechanism 401 can be a gripper assembly or other structure suitable for picking up and placing the process boat 40, and can be configured according to the shape and size of the process boat 40. The boat moving drive mechanism 402 can be a gantry-type three-dimensional translation mechanism, which can drive the boat gripping mechanism 401 to move back and forth in the horizontal and vertical directions, wherein the horizontal direction includes a first direction and a second direction.

[0098] The boat-handling mechanism 401 is driven by the boat-moving drive mechanism 402 to move along the second direction, so that the boat-handling mechanism 401 can span the boat placement platform 300, the boat cooling platform 1000 and the processing device 500, so as to realize the transfer of the process boat 40 between the boat placement platform 300, the boat cooling platform 1000 and the processing device 500.

[0099] The boat-handling mechanism 402 drives the boat-grabbing mechanism 401 to move along the first direction, allowing the boat-grabbing mechanism 401 to span multiple boat placement platforms 300 or multiple boat cooling platforms 1000, thus placing the process boat 40 on different boat placement platforms 300 or different boat cooling platforms 1000. This makes the flow and placement of the process boat 40 more rational, improving not only space utilization but also the flow efficiency of the process boat 40.

[0100] In some embodiments, the loading transfer mechanism 1100 includes a loading docking assembly 1101 and a loading translation assembly 1102. The loading docking assembly 1101 is used to dock with the transfer device 700 to obtain a fully loaded, processed second carrier 30 from the transfer device 700, or to provide an empty second carrier 30 to the transfer device 700. The loading docking assembly 1101 is also used to dock with the transition transfer mechanism 1300 to obtain an empty second carrier 30 from the transition transfer mechanism 1300, or to provide a fully loaded second carrier 30 to the transition transfer mechanism 1300. The loading translation assembly 1102 extends along a first direction and is connected to the loading docking assembly 1101. The loading translation assembly 1102 is used to drive the loading docking assembly 1101 to move along the first direction.

[0101] For example, the loading translation component 1102 can be a gantry-type transverse mechanism, and the loading translation component 1102 can drive the loading docking component 1101 to reciprocate in a first direction.

[0102] For example, the loading docking component 1101 can be docked with the carrier buffer mechanism 702 via a conveyor belt to transfer the second carrier 30. Specifically, the carrier buffer mechanism 702 is a buffer conveyor belt, which is used to carry the second carrier 30 and also to transport the second carrier 30 along a second direction.

[0103] The loading docking assembly 1101 is a loading docking conveyor belt, which is used to carry the second carrier 30 and also to transport the second carrier 30 along the second direction. The surface height of the loading docking conveyor belt is flush with the surface height of the buffer conveyor belt.

[0104] When the loading transfer mechanism 1100 needs to obtain the second carrier 30 from the transfer device 700, firstly, the loading translation component 1102 drives the loading docking component 1101 to move along the first direction so that the loading docking conveyor belt of the loading docking component 1101 docks with the buffer conveyor belt of the carrier buffer mechanism 702; then, the buffer conveyor belt transports the second carrier 30 to the loading docking conveyor belt along the second direction.

[0105] When the feeding transfer mechanism 1100 needs to provide the second carrier 30 to the transfer device 700, firstly, the feeding translation component 1102 drives the feeding docking component 1101 to move along the first direction so that the feeding docking conveyor belt of the feeding docking component 1101 docks with the buffer conveyor belt of the carrier buffer mechanism 702; then, the feeding docking conveyor belt transports the second carrier 30 to the buffer conveyor belt along the second direction.

[0106] It is worth noting that in this embodiment, the loading docking component 1101 and the carrier buffer mechanism 702 adopt a smooth grounding method for the transition of the second carrier 30. In other embodiments, the loading docking component 1101 may also adopt other methods, such as using a gripper structure to grab the second carrier 30 and take it out from the carrier buffer mechanism 702. The specific configuration can be made according to the type of carrier, and this application does not limit it.

[0107] Figure 6 This is a schematic diagram showing the connection between the feeding mechanism, transition mechanism, unloading mechanism, and unloading device of this application.

[0108] Please refer to the following: Figure 6 In some embodiments, the transition transfer mechanism 1300 includes a docking conveying component 1301 and a docking switching component 1302. The docking switching component 1302 is disposed on the side of the feeding transfer mechanism 1100 away from the transfer device 700. The docking switching component 1302 is disposed on the side of the feeding transfer mechanism 1100 away from the feeding transfer mechanism 1100. Thus, the docking switching component 1302 is disposed between the docking conveying component 1301 and the feeding transfer mechanism 1100.

[0109] The docking switching component 1302 is used to transfer the second carrier 30 between the docking conveying component 1301 and the feeding transfer mechanism 1100, and the docking conveying component 1301 is used to transfer the second carrier 30 between the docking switching component 1302 and the unloading transfer mechanism 1200.

[0110] When it is necessary to transport the fully loaded second carrier 30 of the loading transfer mechanism 1100 to the unloading transfer mechanism 1200, the loading transfer mechanism 1100 transports the second carrier 30 to the docking conveyor 1301 through the docking switching component 1302, and the docking conveyor 1301 transports the second carrier 30 to the unloading transfer mechanism 1200.

[0111] When it is necessary to transport the empty second carrier 30 of the unloading transfer mechanism 1200 to the loading transfer mechanism 1100, the unloading transfer mechanism 1200 transports the empty second carrier 30 to the docking conveyor assembly 1301, and the docking conveyor assembly 1301 transports the second carrier 30 to the loading transfer mechanism 1100 through the docking switching assembly 1302.

[0112] Specifically, the docking switching component 1302 is disposed at one end of the docking conveyor component 1301 near the loading transfer mechanism 1100. The docking conveyor component 1301 includes a first transition conveyor line 1301A and a second transition conveyor line 1301B. Both the first transition conveyor line 1301A and the second transition conveyor line 1301B are conveyor belt mechanisms, and the first transition conveyor line 1301A and the second transition conveyor line 1301B are arranged side by side with intervals. In this way, the first transition conveyor line 1301A and the second transition conveyor line 1301B are staggered and can independently convey the second carrier 30.

[0113] The docking switching assembly 1302 has a first state and a second state. When the docking switching assembly 1302 is in the first state, it docks with the first transition conveyor line 1301A, and conveys the second carrier 30 to the first transition conveyor line 1301A so that the first transition conveyor line 1301A can convey the second carrier 30 to the unloading transfer mechanism 1200. When the docking switching assembly 1302 is in the second state, it docks with the second transition conveyor line 1301B, and the second transition conveyor line 1301B conveys the second carrier 30 from the unloading transfer mechanism 1200 to the docking switching assembly 1302.

[0114] It is understood that the first transition conveyor line 1301A and the second transition conveyor line 1301B can respectively realize the conveying of the second carrier 30. That is, while the first transition conveyor line 1301A conveys the fully loaded second carrier 30 to the downward material transfer mechanism 1200, the second transition conveyor line 1301B can also convey the empty second carrier 30 to the upward material transfer mechanism 1100. In this way, the forward conveying and reverse return of the second carrier 30 can be realized simultaneously, improving the turnover efficiency.

[0115] For example, the docking switching component 1302 switches between the first and second states by lifting. Specifically, the first transition conveyor line 1301A and the second transition conveyor line 1301B are arranged in a double-layered configuration, both extending along a second direction and spaced apart vertically. The first transition conveyor line 1301A and the second transition conveyor line 1301B can transport the second carrier 30 in opposite directions. In the example of this application, the first transition conveyor line 1301A is located above the second transition conveyor line 1301B.

[0116] The docking switching assembly 1302 includes a switching conveyor belt 1302A and a switching drive unit 1302B. The switching conveyor belt 1302A is used to carry the second carrier 30 and to transport the second carrier 30 along a second direction. The switching drive unit 1302B is connected to the switching conveyor belt 1302A and is used to drive the switching conveyor belt 1302A to move up and down.

[0117] When the switching drive unit 1302B drives the switching conveyor belt 1302A to rise and fall to the first height, the surface height of the switching conveyor belt 1302A is flush with the surface height of the first transition conveyor line 1301A. At this time, the docking switching assembly 1302 is in the first state, and the switching conveyor belt 1302A can dock with the first transition conveyor line 1301A.

[0118] When the switching drive unit 1302B drives the switching conveyor belt 1302A to rise and fall to the second height, the surface height of the switching conveyor belt 1302A is flush with the surface height of the second transition conveyor line 1301B. At this time, the docking switching assembly 1302 is in the second state, and the switching conveyor belt 1302A can dock with the second transition conveyor line 1301B.

[0119] When the switching drive unit 1302B drives the switching conveyor belt 1302A to rise and fall to the third height, the surface height of the switching conveyor belt 1302A is flush with the surface height of the loading docking assembly 1101. At this time, the switching conveyor belt 1302A can dock with the loading docking assembly 1101. The third height can be configured to be equal to the first height or equal to the second height.

[0120] When it is necessary to transport the fully loaded second carrier 30 to the first transition conveyor line 1301A, firstly, the loading translation component 1102 drives the loading docking component 1101 carrying the fully loaded second carrier 30 to move to one side of the docking switching component 1302, and the switching drive component 1302B drives the switching conveyor belt 1302A to rise and fall to the third height; then, the loading docking conveyor belt of the loading docking component 1101 transports the second carrier 30 to the switching conveyor belt 1302A; then, the switching drive component 1302B drives the switching conveyor belt 1302A to rise and fall to the first height, and the switching conveyor belt 1302A transports the second carrier 30 to the first transition conveyor line 1301A.

[0121] When it is necessary to transport the empty second carrier 30 to the loading docking assembly 1101, firstly, the switching drive unit 1302B drives the switching conveyor belt 1302A to rise and fall to the second height, and the second transition conveyor line 1301B transports the second carrier 30 to the switching conveyor belt 1302A; then, the loading translation assembly 1102 drives the loading docking assembly 1101 carrying the fully loaded second carrier 30 to move to one side of the docking switching assembly 1302, and the switching drive unit 1302B drives the switching conveyor belt 1302A to rise and fall to the third height; then, the switching conveyor belt 1302A transports the second carrier 30 to the loading docking conveyor belt of the loading docking assembly 1101.

[0122] It is worth noting that the docking conveyor assembly 1301 in this embodiment adopts a double-layer conveyor belt to realize the simultaneous conveying of two conveyor lines in different directions. In other embodiments, the docking conveyor assembly 1301 can also adopt other structures, such as adopting a double-rail conveyor line arranged in parallel in the horizontal direction. The specific configuration can be made according to actual needs, and this application does not limit it.

[0123] In some embodiments, the unloading transfer mechanism 1200 includes an unloading conveyor line 1201 and an unloading translation component 1202. The unloading conveyor line 1201 is used to dock with a transition transfer mechanism 1300 to obtain a fully loaded, processed second carrier 30 from the transition transfer mechanism 1300, or to provide an empty second carrier 30 to the transition transfer mechanism 1300. The unloading docking is also used to dock with an unloading device 900 to obtain an empty second carrier 30 from the unloading device 900, or to provide a fully loaded second carrier 30 to the unloading device 900. The unloading translation component 1202 extends along a first direction and is connected to the unloading conveyor line 1201. The unloading translation component 1202 is used to drive the unloading conveyor line 1201 to move along the first direction.

[0124] For example, the unloading translation component 1202 can be a gantry-type transverse mechanism, which can drive the unloading conveyor line 1201 to reciprocate in a first direction.

[0125] For example, the height of the unloading conveyor line 1201 is set to correspond to the height of the transition transfer mechanism 1300. The unloading conveyor line 1201 can transport the second carrier 30 to the transition transfer mechanism 1300 in the horizontal direction to realize the docking between the unloading conveyor line 1201 and the transition transfer mechanism 1300.

[0126] In some embodiments, the unloading transfer mechanism 1200 has two sets, each set of which includes an unloading conveyor line 1201 and an unloading translation component 1202. The two sets of unloading transfer mechanisms 1200 are respectively used to dock with the first transition conveyor line 1301A and the second transition conveyor line 1301B.

[0127] For example, the two sets of feeding and transfer mechanisms 1200 are distributed vertically at intervals. One set of feeding and transfer mechanisms 1200 is defined as the first feeding and transfer mechanism 1200A, and the other set of feeding and transfer mechanisms 1200 is defined as the second feeding and transfer mechanism 1200B.

[0128] The surface height of the feeding conveyor line 1201 of the first feeding transfer mechanism 1200A is flush with the surface height of the first transition conveyor line 1301A. The surface height of the feeding conveyor line 1201 of the second feeding transfer mechanism 1200B is flush with the surface height of the second transition conveyor line 1301B.

[0129] Specifically, when the feeding conveyor line 1201 of the first feeding transfer mechanism 1200A moves to one side of the first transition conveyor line 1301A, the first feeding transfer mechanism 1200A docks with the first transition conveyor line 1301A, and the first transition conveyor line 1301A can transport the fully loaded second carrier 30 to the first feeding transfer mechanism 1200A along the second direction; then, the first feeding transfer mechanism 1200A can transport the fully loaded second carrier 30 to the feeding device 900.

[0130] After the second unloading transfer mechanism 1200B obtains an empty second carrier 30 from the unloading device 900, the unloading conveyor line 1201 of the second unloading transfer mechanism 1200B can be moved to one side of the second transition conveyor line 1301B so that the second unloading transfer mechanism 1200B docks with the second transition conveyor line 1301B; then, the second unloading transfer mechanism 1200B can transport the empty second carrier 30 to the second transition conveyor line 1301B along the second direction.

[0131] It is worth noting that the unloading transfer mechanism 1200 in this embodiment adopts a double-layer conveyor belt, so that the unloading transfer mechanism 1200 can directly connect with the first transition conveyor line 1301A and the second transition conveyor line 1301B, thereby improving the transfer efficiency of the second carrier 30. Furthermore, the conveying method of the unloading transfer mechanism 1200 can be adjusted according to the conveying method of the transition transfer mechanism 1300. That is, if the transition transfer mechanism 1300 can adopt other structures, such as using a double-track conveyor line arranged in parallel in the horizontal direction, the unloading transfer mechanism 1200 can also adaptably adopt a corresponding double-track conveyor line. This application does not impose any limitations on this.

[0132] like Figure 1As shown, in some embodiments, the unloading device 900 includes an integrated receiving mechanism 1400 and / or a guide receiving mechanism 1500. The integrated receiving mechanism 1400 is used to remove multiple processed battery cells 10 from the second carrier 30 and transport the removed battery cells 10 together to a designated position; the empty second carrier 30 can be returned to the unloading transfer mechanism 1200. The guide receiving mechanism 1500 is used to remove multiple processed battery cells 10 from the second carrier 30 and transport the removed battery cells 10 individually to a designated position; the empty second carrier 30 can be returned to the unloading transfer mechanism 1200.

[0133] It is understood that the integrated receiving mechanism 1400 can unload multiple solar cells 10 in a whole stack, and the stacked solar cells 10 can be directly stored or put into the next process as a whole; the guiding receiving mechanism 1500 can support multiple solar cells 10 being divided into multiple individual solar cells 10 for sequential unloading, and the multiple solar cells 10 can be put into the next process individually. In this way, the unloading device 900 can support different unloading modes to suit different application scenarios and facilitate operation and management.

[0134] It is worth noting that the above-described working modes of the integrated receiving mechanism 1400 and the guide plate receiving mechanism 1500 are merely illustrative examples of the optional working modes of the unloading device 900. In other embodiments, the unloading device 900 may also support other unloading modes, and this application does not impose any limitations on this.

[0135] In the example of this application, the unloading device 900 includes an integrated receiving mechanism 1400 and a guide piece receiving mechanism 1500. Both the integrated receiving mechanism 1400 and the guide piece receiving mechanism 1500 are located on the side of the unloading transfer mechanism 1200 away from the transition transfer mechanism 1300, and are spaced apart along a first direction. Specifically, there are two guide piece receiving mechanisms 1500, and the two sets of guide piece receiving mechanisms 1500 are spaced apart along the first direction. Thus, the unloading transfer mechanism 1200 can transfer the second carrier 30 to the integrated receiving mechanism 1400 and the guide piece receiving mechanism 1500 respectively along the first direction.

[0136] For example, the integrated receiving mechanism 1400 passes through a designated operating station. When the fully loaded second carrier 30 is transported to the operating station, the battery cells 10 in the second carrier 30 can be removed by automated equipment or manually, thereby obtaining an empty second carrier 30.

[0137] Specifically, the integrated receiving mechanism 1400 can be connected to the unloading and transfer mechanism 1200 via a conveyor belt to transfer the second carrier 30. The integrated receiving mechanism 1400 adopts a double-layer conveyor belt and includes a first integrated conveyor line and a second integrated conveyor line distributed vertically.

[0138] The first integrated conveyor line carries the second carrier 30 and also conveys the second carrier 30 along a second direction. The surface height of the first integrated conveyor line is flush with the surface height of the unloading conveyor line 1201 of the first unloading transfer mechanism 1200A. The second integrated conveyor line carries the second carrier 30 and also conveys the second carrier 30 along a second direction. The surface height of the second integrated conveyor line is flush with the surface height of the unloading conveyor line 1201 of the second unloading transfer mechanism 1200B. The first and second integrated conveyor lines can convey the second carrier 30 in opposite directions.

[0139] When the first unloading translation component 1202 drives the first integrated receiving mechanism 1400 to move to one end of the integrated receiving mechanism 1400, the integrated receiving mechanism 1400 docks with the first unloading mechanism 1200A. The first unloading mechanism 1200A can transport the fully loaded second carrier 30 to the first integrated conveyor line along the second direction. Then, the first integrated conveyor line transports the fully loaded second carrier 30 to the operating station. The battery cells 10 in the second carrier 30 can be removed by automated equipment or manual means, and the empty second carrier 30 is transported to the second integrated conveyor line. Then, the second integrated conveyor line can transport the empty second carrier 30 to the second unloading mechanism 1200B along the second direction.

[0140] It is worth noting that the integrated receiving mechanism 1400 in this embodiment adopts a double-layer conveyor belt, so that the integrated receiving mechanism 1400 can directly dock with the first unloading mechanism 1200A and the second unloading mechanism 1200B, thereby improving the transfer efficiency of the second carrier 30. Furthermore, the conveying method of the integrated receiving mechanism 1400 can be adjusted according to the conveying method of the unloading transfer mechanism 1200. That is, if the unloading transfer mechanism 1200 can adopt other structures, such as a double-track conveyor line arranged in parallel in the horizontal direction, the integrated receiving mechanism 1400 can also adaptably adopt a corresponding double-track conveyor line. This application does not impose any limitations on this.

[0141] Figure 7 This is a schematic diagram of the material feeding and transfer mechanism and the guide plate receiving mechanism provided in this application.

[0142] Please refer to the following: Figure 7In some embodiments, the sheet receiving mechanism 1500 includes a carrier transmission assembly 1600, a sheet transmission assembly 1700, and a sheet transfer assembly 1800. The carrier transmission assembly 1600 is disposed on one side of the unloading transfer mechanism 1200, with one end capable of docking with the unloading transfer mechanism 1200. The carrier transmission assembly 1600 carries the second carrier 30 and transports the second carrier 30 along a second direction. The sheet transmission assembly 1700 is disposed on one side of the carrier transmission assembly 1600, carrying the battery cell 10 and transporting the battery cell 10 along a second direction. The sheet transfer assembly 1800 is disposed between the carrier transmission assembly 1600 and the sheet transmission assembly 1700. The sheet transfer assembly 1800 grips the battery cell 10 from the fully loaded second carrier 30 of the carrier transmission assembly 1600 and transfers the battery cell 10 to the sheet transmission assembly 1700.

[0143] Specifically, the working method of the sheet receiving mechanism 1500 is as follows: First, the unloading transfer mechanism 1200 transports the fully loaded second carrier 30 to the carrier transfer assembly 1600, and the carrier transfer assembly 1600 transports the fully loaded second carrier 30 to the designated position; then, the sheet transfer assembly 1800 grabs the battery cell 10 from the fully loaded second carrier 30 and transports the battery cell 10 to the sheet transfer assembly 1700; then, the sheet transfer assembly 1700 transports the battery cell 10 to the next process, and the carrier transfer assembly 1600 transports the empty second carrier 30 back to the unloading transfer mechanism 1200.

[0144] For example, the sheet conveying assembly 1700 is a conveyor belt mechanism, on which multiple solar cells 10 can be laid flat and placed on the sheet conveying assembly 1700. The sheet conveying assembly 1700 transports the multiple solar cells 10 to the outside of the equipment so that a single solar cell 10 can be directly put into the next process.

[0145] For example, the wafer transfer assembly 1800 includes a wafer gripper 1801 and a transfer drive 1802, with the transfer drive 1802 connected to the wafer gripper 1801. The wafer gripper 1801 grips the battery wafer 10, and the transfer drive 1802 drives the wafer gripper 1801 to move to a designated position to grip the battery wafer 10, or to place the gripped battery wafer 10 at a designated position. The transfer drive 1802 can be a gantry-type three-dimensional translation mechanism, which can drive the wafer-grabbing component to reciprocate horizontally and vertically. The wafer gripper 1801 can be a suction cup or gripper, or other structure suitable for gripping the battery wafer 10, and can be configured according to the shape and material of the battery wafer 10, or according to the type of carrier.

[0146] In some embodiments, the carrier transfer assembly 1600 includes a carrier conveyor belt 1601 and a carrier return unit 1602. The carrier conveyor belt 1601 is disposed on one side of the unloading transfer mechanism 1200 and is used to dock with the unloading transfer mechanism 1200 to transfer the second carrier 30. The carrier return unit 1602 is disposed at the end of the carrier conveyor belt 1601 away from the unloading transfer mechanism 1200 and is used to switch the conveying direction of the second carrier 30 on the carrier conveyor belt 1601.

[0147] Specifically, the carrier conveyor belts 1601 are arranged in multiple sets, and these sets are spaced apart along a first direction. A guide plate transfer assembly 1700 is disposed between the multiple sets of carrier conveyor belts 1601. A carrier return unit 1602 is used to transfer the second carrier 30 between the multiple sets of carrier return units 1602. A guide plate transfer assembly 1800 is used to transfer the battery cell 10 between the multiple sets of carrier return units 1602 and the adjacent guide plate transfer assembly 1700. This improves the transfer efficiency of the battery cell 10 and the second carrier 30. In the example of this application, each carrier transfer assembly 1600 has two sets of carrier conveyor belts 1601, which are distributed on both sides of the guide plate transfer assembly 1700.

[0148] For example, the carrier conveyor belt 1601 includes a first carrier conveyor line 1601A and a second carrier conveyor line 1601B, wherein the first carrier conveyor line 1601A and the second carrier conveyor line 1601B are arranged side by side with intervals. The first carrier conveyor line 1601A is used to dock with the first unloading mechanism 1200A and is used to carry the second carrier 30 and convey the second carrier 30 along the second direction. The surface height of the first carrier conveyor line 1601A is flush with the surface height of the unloading conveyor line 1201 of the first unloading transfer mechanism 1200A.

[0149] The second carrier conveyor line 1601B is used to dock with the second unloading mechanism 1200B. The second carrier conveyor line 1601B is used to carry the second carrier 30 and transport the second carrier 30 along the second direction. The surface height of the second carrier conveyor line 1601B is flush with the surface height of the unloading conveyor line 1201 of the second unloading transfer mechanism 1200B. The first carrier conveyor line 1601A and the second carrier conveyor line 1601B can transport the second carrier 30 in opposite directions.

[0150] For example, the vehicle return unit 1602 includes a vehicle buffer 1603 and a return drive 1604, wherein the vehicle buffer 1603 is used to grab the second vehicle 30, and the return drive 1604 is connected to the vehicle buffer 1603 and is used to drive the vehicle buffer 1603 to move.

[0151] The carrier transfer assembly 1600 operates as follows: First, the first carrier conveyor line 1601A receives a fully loaded second carrier 30 from the first unloading mechanism 1200A and conveys the fully loaded second carrier 30 towards the carrier return unit 1602; then, the sheet transfer assembly 1800 removes the battery cells 10 from the second carrier 30 to obtain an empty second carrier 30; then, the first carrier conveyor line 1601A conveys the empty second carrier 30 to the carrier return unit 1602; then, the return drive 1604 drives... The carrier buffer 1603 is moved to the first carrier conveyor line 1601A, where it acquires an empty second carrier 30. Then, the return drive 1604 drives the carrier buffer 1603 to move to the second carrier conveyor line 1601B, where it feeds the empty second carrier 30 into the first carrier conveyor line 1601A. Then, the second carrier conveyor line 1601B conveys the empty second carrier 30 to the unloading transfer mechanism 1200, so that the unloading transfer mechanism 1200 acquires the empty second carrier 30.

[0152] For example, the first carrier conveyor line 1601A and the second carrier conveyor line 1601B are arranged in a double layer, one above the other. The first transition conveyor line 1301A and the second transition conveyor line 1301B both extend along the second direction, and the first transition conveyor line 1301A and the second transition conveyor line 1301B are distributed at intervals in the vertical direction. The first transition conveyor line 1301A is located above the second transition conveyor line 1301B.

[0153] The vehicle buffer 1603 can be a conveyor belt mechanism. The vehicle buffer 1603 can move to a first position or a second position under the drive of the return drive 1604.

[0154] When the vehicle buffer 1603 is in the first position, its surface height is flush with the surface height of the first vehicle conveyor line 1601A, and it can dock with the first vehicle conveyor line 1601A. When the vehicle buffer 1603 is in the second position, its surface height is flush with the surface height of the second vehicle conveyor line 1601B, and it can dock with the second vehicle conveyor line 1601B.

[0155] It is worth noting that the carrier transfer assembly 1600 in this embodiment adopts a double-layer conveyor belt, so that the carrier transfer assembly 1600 can directly dock with the first unloading mechanism 1200A and the second unloading mechanism 1200B, thereby improving the transfer efficiency of the second carrier 30. Furthermore, the conveying method of the carrier transfer assembly 1600 can be adjusted according to the conveying method of the unloading transfer mechanism 1200. That is, if the unloading transfer mechanism 1200 can adopt other structures, such as a double-rail conveyor line arranged in parallel in the horizontal direction, the carrier transfer assembly 1600 can also adaptably adopt a corresponding double-rail conveyor line. This application does not impose any limitations on this.

Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
