Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, specifically to a flower basket conveying mechanism and loading / unloading system. Background Technology

[0002] As photovoltaic product technology continues to iterate and update, the requirements for the capacity of loading and unloading systems are becoming increasingly higher. In the process of cell production, multiple process steps are required. Typically, the cells are placed in baskets and transported by AGVs (Automated Guided Vehicles). Each step has different requirements for the baskets. For example, in the cell production process, processes such as texturing before coating require the use of liquid to treat the cells. Therefore, in the coating process, the baskets used to transport the cells into the boat are wet baskets. In the processes after coating, such as screen printing and sintering, the baskets cannot contain liquid. Therefore, the baskets used to transport the cells out of the boat after coating are dry baskets.

[0003] In the coating process, multiple loading and unloading operations are required to change the carrier of the solar cells. The solar cells are guided between the basket and the boat through the guiding device. Solar cells that have not undergone coating or other processes are guided from the wet basket into the boat, and solar cells that have undergone coating or other processes are exported from the boat into the dry basket.

[0004] AGV carts can be used to transport flower baskets. The flower basket conveying mechanism transports the flower baskets between the AGV cart and the guide device. However, due to reasons such as upstream and downstream process equipment, the load capacity of dry and wet flower baskets may be different. During the guide and transportation process, the flower basket transporting device and the guide device may wait, resulting in low overall production efficiency. Utility Model Content

The first motor drives the first lead screw to rotate relative to the first base. One end of the first lead screw is located at the handling station, and the other end is located at the guide plate station. The second conveying unit includes a second motor, a second base, a second lead screw, a second slider, and a second platform. The second platform is connected to the second slider and is used to carry the second flower basket. The second slider has a threaded hole that mates with the second lead screw. The second motor drives the second lead screw to rotate relative to the second base. One end of the second lead screw is located at the handling station, and the other end is located at the guide plate station.

[0009] Optionally, the first conveying unit further includes a first slide rail disposed on the first base, the first slide rail being parallel to the first lead screw, and the first slider being slidably disposed on the first slide rail; the second conveying unit further includes a second slide rail disposed on the second base, the second slide rail being parallel to the second lead screw, and the second slider being slidably disposed on the second slide rail.

[0014] Optionally, the guide device includes a suction cup robot, which is provided with a suction cup part for adsorbing the battery cells.

[0015] The flower basket conveying mechanism and loading / unloading system provided in this application have the following technical advantages compared to the prior art:

[0028] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] As photovoltaic product technology continues to iterate and update, the requirements for the capacity of loading and unloading systems are becoming increasingly higher. In the process of cell production, multiple process steps are required. Typically, the cells are placed in baskets and transported by AGVs (Automated Guided Vehicles). Each step has different requirements for the baskets. For example, in the cell production process, processes such as texturing before coating require the use of liquid to treat the cells. Therefore, in the coating process, the baskets used to transport the cells into the boat are wet baskets. In the processes after coating, such as screen printing and sintering, the baskets cannot contain liquid. Therefore, the baskets used to transport the cells out of the boat after coating are dry baskets.

[0030] In the coating process, multiple loading and unloading operations are required to change the carrier of the solar cells. The solar cells are guided between the basket and the boat through the guiding device. Solar cells that have not undergone coating or other processes are guided from the wet basket into the boat, and solar cells that have undergone coating or other processes are exported from the boat into the dry basket.

[0031] This application provides a flower basket conveying mechanism and a loading / unloading system. The loading / unloading system includes an AGV trolley, dry flower baskets, wet flower baskets, a flower basket conveying mechanism, and a guide device 6. The AGV trolley is used to transport flower baskets, including wet flower baskets carrying wafers, empty wet flower baskets, dry flower baskets carrying wafers, and empty dry flower baskets. The flower basket conveying mechanism is used to transport dry flower baskets and wet flower baskets between the AGV trolley and the guide device 6. The guide device 6 is used to remove battery cells from the wet flower baskets carrying wafers and insert them into a boat, and also to remove the processed battery cells from the boat and place them into the empty dry flower baskets.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the flower basket conveying mechanism includes a flower basket moving device 1 and a first conveying section 2 and a second conveying section 3 arranged in parallel. The flower basket conveying mechanism includes a handling station 4 and a guide plate station 5. The flower basket moving device 1 is located on one side of the handling station 4 and is used to handle the first flower basket and the second flower basket. The guide plate device 6 is located on one side of the guide plate station 5.

[0033] The first conveying unit 2 is used to convey a first flower basket, including a first flower basket with a sheet and an empty first flower basket, between the conveying station 4 and the guide sheet station 5. The second conveying unit 3 is used to convey a second flower basket, including a second flower basket with a sheet and an empty second flower basket, between the conveying station 4 and the guide sheet station 5.

[0034] In the first and second flower baskets, one is a dried flower basket and the other is a wet flower basket. Either the first flower basket can be dried and the second wet, or vice versa. The following explanation will use the example of the first flower basket being dried and the second wet.

[0035] The conveying process of the wet flower basket is as follows: the flower basket moving device 1 moves the wet flower basket carrying the cells in the AGV trolley to the conveying station 4. The second conveying unit 3 conveys the wet flower basket to the guiding station 5. The guiding device 6 takes out the battery cells from the wet flower basket and inserts them into the boat. After the wet flower basket at the guiding station 5 is empty, the second conveying unit 3 conveys the empty wet flower basket to the conveying station 4, and the flower basket moving device 1 moves the empty wet flower basket to the AGV trolley. Then the wet flower basket carrying the cells in the AGV trolley is moved to the conveying station 4, and so on.

[0036] The process of transporting dried flower baskets is as follows: the flower basket moving device 1 transports the empty dried flower baskets of the AGV trolley to the transport station 4, the first conveying unit 2 transports the empty dried flower baskets to the sheet guiding station 5, the sheet guiding device 6 takes out the processed battery cells from the boat and puts them into the empty dried flower baskets, after the dried flower baskets are full of battery cells, the first conveying unit 2 transports the dried flower baskets carrying the cells to the transport station 4, and the flower basket moving device 1 transports the dried flower baskets carrying the cells to the AGV trolley, and then transports the empty dried flower baskets of the AGV trolley to the transport station 4, and so on.

[0037] Due to reasons such as upstream and downstream process equipment, the amount of cells carried in dry and wet baskets may be different, that is, the amount of cells carried in the first basket and the second basket may be different, with the amount of cells carried in the first basket being greater than that in the second basket. In order to achieve a balance of cell quantity, the number of first baskets transported by the first conveying unit 2 is less than the number of second baskets transported by the second conveying unit 3. If the basket conveying mechanism is only equipped with one first conveying unit 2 and one second conveying unit 3, it will cause a certain waiting time for the basket handling device 1 and the cell guiding device 6, resulting in low overall production efficiency.

[0038] In this embodiment, the number of second conveying units 3 is greater than the number of first conveying units 2. That is, the number of sheets carried in the first basket is greater than the number of sheets carried in the second basket. The number of first conveying units 2 is at least one, and the number of second conveying units 3 is at least two. Furthermore, the sum of the number of sheets carried in the second baskets conveyed by each second conveying unit 3 is equal to the sum of the number of sheets carried in the first baskets conveyed by the first conveying unit 2. In this way, the quantity balance of the solar cells can be guaranteed, and the system can operate stably.

[0039] The first conveying section 2 and the second conveying section 3 each independently convey flower baskets. Each second conveying section 3 also independently conveys its own second flower basket. Taking one first conveying section 2 and two second conveying sections 3 as an example... Figure 1 In the state shown, the first flower basket conveyed by the first conveyor 2 is located at the guide plate station 5, and the second flower baskets conveyed by the two second conveyor 3s are both located at the handling station 4; as shown Figure 2 In the state shown, the first flower basket conveyed by the first conveyor 2 is located at the handling station 4, and the second flower baskets conveyed by the two second conveyor 3s are both located at the guide plate station 5; as shown Figure 3 In the state shown, the first flower basket conveyed by the first conveying unit 2 is located at the handling station 4, the second flower basket conveyed by one second conveying unit 3 is located at the handling station 4, and the second flower basket conveyed by another second conveying unit 3 is located at the guide plate station 5. In each state, there are flower baskets at the handling station 4 and the guide plate station 5. This ensures that the flower basket handling device 1 and the guide plate device 6 are always in working condition, avoiding time waste due to waiting, thereby effectively improving production efficiency and achieving high capacity for automated insertion and unloading.

[0040] The first basket carries twice the number of solar cells as the second basket, and the number of second conveying units 3 is twice the number of first conveying units 2. For example, if the first basket carries 120 solar cells and the second basket carries 0, there is one first conveying unit 2 and two second conveying units 3. This arrangement simplifies the overall structure while ensuring a balanced transport of solar cells. Of course, in this embodiment, there is no limitation on the number of solar cells carried in the first and second baskets; the number of first conveying units 2 and second conveying units 3 can be set according to the number of solar cells carried in the first and second baskets.

[0041] In this embodiment, the first conveying unit 2 includes a first motor, a first base 21, a first lead screw 22, a first slider, and a first platform 23. The first slider is connected to the first platform 23, which is used to support the first flower basket. The first slider has a threaded hole, and the first lead screw 22 passes through the threaded hole and is threadedly engaged with the first slider. One end of the first lead screw 22 is located at the transport station 4, and the other end is located at the guide plate station 5. The first motor is used to drive the first lead screw 22 to rotate relative to the first base 21. Through the threaded engagement of the first lead screw 22 with the threaded hole, the first slider can drive the first flower basket to move along the axial direction of the first lead screw 22 to the transport station 4 and the guide plate station 5 via the first platform 23.

[0042] The second conveying unit 3 includes a second motor, a second base 31, a second lead screw 32, a second slider, and a second platform 33. The second slider is connected to the second platform 33, which carries the second flower basket. The second slider has a threaded hole, through which the second lead screw 32 passes and is threadedly engaged with the second slider. One end of the second lead screw 32 is located at the transport station 4, and the other end is located at the guide plate station 5. The second motor drives the second lead screw 32 to rotate relative to the second base 31. Through the threaded engagement of the second lead screw 32 with the threaded hole, the second slider can move the second flower basket along the axial direction of the second lead screw 32 to the transport station 4 and the guide plate station 5 via the second platform 33. There are two second lead screws 32, which can be of the same length or one longer than the other.

[0043] Each conveyor section can have its own base, or some conveyor sections can share a base, such as... Figure 1 , Figure 2 and Figure 3 In the embodiment shown, the two second conveying units 3 share a second base 31 to simplify the overall structure.

[0044] Of course, in this embodiment, the specific structure of the first conveying unit 2 and the second conveying unit 3 is not limited. For example, the conveying unit can also be configured to include a drive cylinder and a platform, with the piston rod of the drive cylinder connected to the platform, and the platform used to carry the flower basket. The flower basket can be moved by driving the drive cylinder. When the conveying unit is configured to include a motor lead screw assembly, the driving force can be kept stable, and the conveying position of the flower basket can be accurately controlled.

[0045] To further ensure the stability of the flower basket during transport, the first conveying unit 2 also includes a first slide rail located on the first base 21. The first slide rail is parallel to the first lead screw 22, and a first slider is slidably fitted onto the first slide rail. The first slide rail guides the movement of the first slider. While the first motor drives the first lead screw 22 to rotate, causing the first slider to move along the axial direction of the lead screw, the first slider also slides along the first slide rail, preventing it from rotating around the first lead screw 22. This ensures the stability of the first flower basket as it moves via the first platform 23. Similarly, the second conveying unit 3 also includes a second slide rail located on the second base 31. The second slide rail is parallel to the second lead screw 32, and a second slider is slidably mounted on the second slide rail. The guiding function of the second slide rail ensures the stability of the second flower basket during transport.

[0046] In this embodiment, there are no restrictions on the specific structure of the first slide and the second slide. Taking the first slide as an example, the first slide can be a slide rail, a slide groove, or a slide rod. In this case, the first slider is also provided with a through hole and is sleeved on the outside of the slide rod, and can move along the axial direction of the slide rod.

[0047] The flower basket moving device 1 is equipped with at least two fixing members 11, which are used to fix to the first or second flower basket. This arrangement allows the flower basket moving device 1 to move at least two flower baskets at a time, effectively improving the efficiency of flower basket handling and thus increasing production efficiency. The number of fixing members 11 in the flower basket moving device 1 can be set according to actual needs, such as... Figure 1 , Figure 2 and Figure 3 In the embodiment shown, there is one first conveying unit 2 and two second conveying units 3. The flower basket conveying mechanism can carry up to three flower baskets at the same time. The flower basket moving device 1 only needs two fixing parts 11 to meet the handling efficiency requirements, and the overall structure is simple.

[0048] Furthermore, in this embodiment, there are no restrictions on the specific structure of the fixing member 11. The fixing member 11 can be the fixing claw of the flower basket moving robot, and can be fixed to the flower basket by means of clamping, suction cup, etc.

[0049] Each conveying unit is independent of the others. Therefore, each conveying unit transports the flower basket to different positions of the handling station 4 and the guide plate station 5. The flower basket moving device 1 includes a flower basket moving robot, a frame and a drive unit. The flower basket moving robot is movably mounted on the frame. The drive unit is used to drive the flower basket moving robot to move along the frame to the side of each conveying unit facing the handling station 4. The flower basket moving robot can move the flower basket between the handling station 4 and the AGV trolley.

[0050] The frame can also be equipped with guide rails to guide the flower basket moving robot, enabling it to accurately move flower baskets between the four sides of the transport stations in each conveying section and between the AGV trolley. There are no restrictions on the specific structure of the drive unit; it can be a motor screw assembly or a drive cylinder (such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder), etc.

[0051] Of course, in this embodiment, the flower basket moving device 1 may not be equipped with a drive unit and a frame. Instead, a robot arm is set up through the flower basket moving robot, and the movement of the robot arm drives the fixed part 11 to move to the transport station 4 side of each conveying unit.

[0052] The basket conveying mechanism may further include a tooth-shaping device located at the guide plate station 5. This tooth-shaping device is used to arrange the position of the battery cells in the basket located at the guide plate station 5. During the guiding operation of the guide plate device 6 on the battery cells in the basket located at the guide plate station 5, the tooth-shaping device can arrange the position of the battery cells in the basket. The arrangement process does not require additional time, thereby improving production efficiency while arranging the battery cells. In this embodiment, the specific structure of the tooth-shaping device is not limited, and an existing tooth-shaping device can be used to arrange the position of the battery cells in the basket.

[0053] The guide device 6 includes a suction cup robot equipped with a suction cup for adsorbing battery cells. The battery cells are placed and removed by adsorbing them through the suction cup. Of course, in this embodiment, the specific structure of the guide device 6 is not limited. For example, grippers or similar devices can be used to pick up and place the battery cells. However, using the suction cup to adsorb the battery cells simplifies the overall structure and avoids damage to the battery cells during the process.

[0054] Furthermore, the guide plate device 6 may also include a drive component, which drives the suction cup robot to move between the guide plate station 5 of each conveying section and the boat.
