Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery cell transportation technology, and in particular to a battery cell loading module. Background Technology
[0002] In the production of photovoltaic module cells, the cells need to be loaded first and transported to the required location. Then, the solder ribbon is positioned onto the cells so that it aligns with the grid lines on the cell surface. Current cell loading technologies include basket loading, robotic arm loading, and manual loading.
[0003] When using robotic arms to handle battery cells, the arms typically need to switch between two or more workstations to move cells from one workstation to another. When the robotic arm rotates and moves a battery cell from one workstation to another, the change in rotation angle causes the angle of the moved cell to shift, which is detrimental to subsequent processing. Utility Model Content
[0004] The purpose of this utility model is to provide a battery cell loading module that is less likely to cause the angle of the battery cells to shift after transportation, which is beneficial to the subsequent processing of the battery cells.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A battery cell loading module, comprising:
[0007] frame;
[0008] A feeding mechanism is installed on the frame and is used to transport battery cells;
[0009] A straightening mechanism is provided on the frame. The straightening mechanism includes a placement frame and a straightening component. The placement frame is used to attach the battery cell, and the straightening component is used to adjust the position of the battery cell relative to the placement frame.
[0010] A conveying mechanism is disposed on the frame and located between the feeding mechanism and the alignment mechanism. The conveying mechanism includes a first drive assembly and a cell gripping assembly. The cell gripping assembly includes a connector and a cell gripper. The cell gripper is disposed on the connector and can grip the battery cell of the feeding mechanism or release the battery cell to the placement rack. The first drive assembly is used to drive the connector to rotate and can also drive the cell gripper to rotate relative to the connector.
[0011] In some possible implementations, the first drive assembly includes a first drive member, an output shaft, a gear, and a timing belt. The first drive member is disposed on the frame. The two ends of the output shaft are fixedly connected to the output end of the first drive member and the connector, respectively. The first drive member is used to drive the output shaft to rotate, thereby driving the connector to rotate. The gear is sleeved and fixed outside the output shaft. The gripper is rotatably connected to the connector. The timing belt surrounds the gear and the gripper. The timing belt meshes with the gear and the gripper.
[0012] In some possible implementations, the alignment component includes a second drive component, a fixing member, and an alignment wheel. The second drive component is used to drive the fixing member to move. The alignment wheel is disposed on the fixing member and is rotatable relative to the fixing member and can abut against the edge of the battery cell.
[0013] In some possible implementations, the battery cell loading module further includes a transport mechanism that can lift the battery cell to disengage it from the placement rack, and the transport mechanism can move the lifted battery cell along the length of the placement rack.
[0014] In some possible implementations, the placement rack includes two frames spaced apart, with the two ends of the battery cell respectively able to overlap the two frames, and the transport mechanism located in the gap between the two frames.
[0015] In some possible implementations, the feeding mechanism includes a placement component and a transfer component. The placement component is fixed to the frame, and the transfer component is used to move the battery cell and move the battery cell to the placement component. The gripper can grip the battery cell on the placement component.
[0016] In some possible implementations, the transfer assembly includes a transfer drive, a transmission component, and at least two stacking components. The transfer drive is fixed to the frame, and all the stacking components are fixed to the transmission component at intervals in the vertical direction. The transfer drive is tractively connected to the transmission component. The transfer drive enables the stacking components to move vertically on the transmission component and selectively aligns the stacking components with the placement assembly. The stacking components are used to place the battery cells and can move the battery cells to the placement assembly.
[0017] In some possible implementations, the feeding mechanism further includes a detection component that is communicatively connected to the transmission drive and is used to detect whether the stacking component and the placement assembly are aligned.
[0018] In some possible implementations, the placement assembly includes a fourth drive member and a first conveyor belt, the fourth drive member being tractively connected to the first conveyor belt, the first conveyor belt being capable of moving the battery cells.
[0019] In some possible implementations, there are two feeding mechanisms, which are arranged opposite to each other on the frame, and both feeding mechanisms can move the battery cells to the transport mechanism.
[0020] The beneficial effects of this utility model are:
[0021] This utility model provides a battery cell loading module, including a frame, a loading mechanism, a centering mechanism, and a transport mechanism. When transporting battery cells, the transport mechanism uses a gripper to pick up the cells from the loading mechanism. Then, a first drive assembly drives a connecting member to rotate, moving the gripper above the placement rack. During this rotation, the angle of the battery cell on the gripper changes. The first drive assembly then drives the gripper to rotate relative to the connecting member, resetting the angle of the battery cell on the gripper so that the angle of the battery cell released onto the placement rack is the same as the angle of the battery cell on the loading mechanism. This design prevents the angle of the battery cell from shifting after transport, which is beneficial for subsequent processing. Furthermore, the centering mechanism adjusts the position of the battery cell relative to the placement rack, further ensuring the accuracy of the battery cell angle after transport and ensuring that the angle of the battery cell is the same before and after transport.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0036] like Figures 1 to 4As shown, this utility model provides a battery cell loading module, including a frame, a loading mechanism 1, a straightening mechanism 2, and a conveying mechanism 3. The loading mechanism 1 is disposed on the frame and is used to transport battery cells 100. The straightening mechanism 2 is disposed on the frame and includes a placement frame 21 and a straightening component. The placement frame 21 is used to overlap the battery cells 100, and the straightening component is used to adjust the position of the battery cells 100 relative to the placement frame 21. The conveying mechanism 3 is disposed on the frame and located between the loading mechanism 1 and the straightening mechanism 2. The conveying mechanism 3 includes a first driving component and a cell gripping component. The cell gripping component includes a connector 31 and a cell gripper 32. The cell gripper 32 is disposed on the connector 31 and can grip the battery cells 100 of the loading mechanism 1 or release the battery cells 100 to the placement frame 21. The first driving component is used to drive the connector 31 to rotate and can also drive the cell gripper 32 to rotate relative to the connector 31. When the conveying mechanism 3 conveys the battery cell 100, the gripper 32 picks up the battery cell 100 from the loading mechanism 1, and then drives the connecting member 31 to rotate via the first drive assembly, rotating the gripper 32 above the placement rack 21. During the rotation, the angle of the battery cell 100 on the gripper 32 changes. Then, the first drive assembly drives the gripper 32 to rotate relative to the connecting member 31, restoring the angle of the battery cell 100 on the gripper 32 so that the angle of the battery cell 100 released on the placement rack 21 is the same as the angle of the battery cell 100 on the loading mechanism 1. This setting makes it less likely for the angle of the battery cell 100 to shift after conveying, which is beneficial for subsequent processing of the battery cell 100. On this basis, the alignment mechanism 2 adjusts the position of the battery cell 100 relative to the placement rack 21 to further ensure the accuracy of the angle of the battery cell 100 after conveying, making the angle of the battery cell 100 the same before and after conveying.
[0037] Optionally, the first drive assembly includes a first drive member 33, an output shaft 34, a gear 35, and a timing belt 36. The first drive member 33 is mounted on the frame. The two ends of the output shaft 34 are fixedly connected to the output end of the first drive member 33 and the connector 31, respectively. The first drive member 33 is used to drive the output shaft 34 to rotate, thereby driving the connector 31 to rotate. The gear 35 is sleeved and fixed outside the output shaft 34. The gripper 32 is rotatably connected to the connector 31. The timing belt 36 surrounds the gear 35 and the gripper 32. The timing belt 36 meshes with the gear 35 and the gripper 32. When the first driving member 33 drives the output shaft 34 to rotate, the connecting member 31 rotates to change the position of the gripper 32, thereby changing the angle of the battery cell 100. At the same time, the gear 35 rotates, driving the synchronous belt 36 to move, which in turn causes the gripper 32 to rotate relative to the connecting member 31, resetting the angle of the battery cell 100. This ensures that the angle of the battery cell 100 released on the placement rack 21 is the same as the angle of the battery cell 100 on the feeding mechanism 1. This configuration allows for synchronous resetting while changing the angle of the battery cell 100, improving work efficiency. Specifically, a transmission wheel 321 is provided at the top of the gripper 32, and the other end of the synchronous belt 36 meshes with the transmission wheel 321. Optionally, the first driving member 33 is a rotary motor. Specifically, one gripper 32 can be provided, or two grippers 32 can be provided. If only one gripper 32 is provided, one end of the synchronous belt 36 meshes with the gear 35, and the other end of the synchronous belt 36 meshes with the gripper 32.
[0038] In other embodiments, the first driving assembly includes a second driving member and a third driving member. The second driving member is disposed on the frame and is used to drive the connector 31 to rotate. The third driving member is fixed to the connector 31 and is used to drive the gripper 32 to rotate relative to the connector 31. When the second driving member drives the connector 31 to rotate, it changes the position of the gripper 32 and thus changes the angle of the battery cell 100. When the gripper 32 rotates above the placement rack 21, the third driving member drives the gripper 32 to rotate relative to the connector 31, so that the angle of the battery cell 100 is reset, thereby making the angle of the battery cell 100 released on the placement rack 21 the same as the angle of the battery cell 100 on the feeding mechanism 1. Optionally, both the second driving member and the third driving member are rotary motors.
[0039] Specifically, the bottom end of the gripper 32 is connected to several vacuum suction cups 322, each connected to a cylinder, and the vacuum suction cups 322 have both suction and desiccation states. By gripping the battery cell 100 using the vacuum suction cups 322, damage to the battery cell 100 can be avoided.
[0040] Optionally, such as Figure 3As shown, the alignment assembly includes a second drive assembly, a fixing member 22, and an alignment wheel 23. The second drive assembly drives the fixing member 22 to move. The alignment wheel 23 is disposed on the fixing member 22 and can rotate relative to the fixing member 22, and can abut against the edge of the battery cell 100. Specifically, multiple alignment wheels 23 are spaced apart on the fixing member 22. When adjusting the position of the battery cell 100 relative to the placement frame 21, the second drive assembly drives the fixing member 22 to move, causing the alignment wheel 23 to approach the edge of the battery cell 100. Then, the fixing member 22 continues to move, and while the alignment wheel 23 abuts against the edge of the battery cell 100, it pushes the battery cell 100 to move, thereby achieving position adjustment. The alignment wheel 23 rotates relative to the fixing member 22 to avoid damage to the battery cell 100 by the alignment assembly.
[0041] Optionally, the battery cell loading module also includes a transport mechanism 4. The transport mechanism 4 can lift the battery cell 100 to disengage it from the placement rack 21, and can move the lifted battery cell 100 along the length of the placement rack 21. By lifting and moving the lifted battery cell 100, the battery cell 100 is transported and then placed on the placement rack 21, positioning it at a designated workstation. This allows for the transport of the battery cell 100 to different workstations, facilitating subsequent processing at different workstations. Furthermore, the battery cell 100 can be transported according to actual work requirements, and the transport to each workstation does not interfere with each other. Specifically, the battery cell 100 can be moved from the battery cell 100 alignment workstation on the placement rack 21 to the battery cell 100 dicing workstation, and then from the battery cell 100 dicing workstation to the battery cell 100 reversing workstation, realizing step-by-step transport between workstations. Optionally, the transport mechanism 4 includes a first moving component, a second moving component, and a lifting member 41. The output end of the first moving component is used to drive the second moving component to move along the length direction of the placement frame 21, and the output end of the second moving component is used to drive the lifting member 41 to move in the vertical direction. The first moving component and the second moving component are mature technologies in related fields, and will not be described in detail in this embodiment.
[0042] Optionally, such as Figure 1 and Figure 3As shown, the placement rack 21 includes two frame bodies 211, which are spaced apart. The two ends of the battery cell 100 can overlap the two frame bodies 211 respectively. The transport mechanism 4 is located within the gap between the two frame bodies 211. This arrangement simplifies the structure of the placement rack 21, allowing the transport mechanism 4 to be placed within it, saving space and not hindering the movement of the battery cell 100 by the transport mechanism 4. Furthermore, the placement rack 21 also includes at least one support member 212, located between the two frame bodies 211. The support member 212 is fixed to the frame body 211 by a connecting plate. The battery cell 100 can overlap the two frame bodies 211 and the support member 212. Through-gap gaps 213 are formed between the support member 212 and the frame body 211, as well as between adjacent support members 212. The lifting member 41 can pass through the through-gap gap 213 and lift the battery cell 100. By setting the support member 212, the support of the placement rack 21 for the battery cell 100 is made more reliable.
[0043] Optionally, in this embodiment, there are two feeding mechanisms 1, which are arranged opposite to each other on the frame. Both feeding mechanisms 1 can move the battery cells 100 to the conveying mechanism 3. Specifically, one feeding mechanism 1 can move the battery cells 100 along the length of the placement frame 21, and the other feeding mechanism 1 can move the battery cells 100 in the opposite direction to the other feeding mechanism 1. With this arrangement, after the battery cells 100 on one feeding mechanism 1 are transported, the conveying mechanism 3 can transport the battery cells 100 on the other feeding mechanism 1, which can realize continuous transport of the battery cells 100, improve work efficiency, and has a simple and compact structure.
[0044] Optionally, in this embodiment, the feeding mechanism 1 includes a placement component 11 and a transfer component 12. The placement component 11 is fixed to the frame, and the transfer component 12 is used to move the battery cell 100 and move the battery cell 100 to the placement component 11. The gripper 32 can grip the battery cell 100 on the placement component 11. The transfer component 12 and the placement component 11 are set separately and do not affect each other. When the conveying mechanism 3 grips the battery cell 100, it does not affect the operation of the transfer component 12.
[0045] Furthermore, in this embodiment, the transmission assembly 12 includes a transmission drive, a transmission component, and at least two stacking components 121. The transmission drive is fixed to the frame, and all stacking components 121 are fixed to the transmission component at intervals along the vertical direction. The transmission drive is connected to the transmission component, enabling the stacking components 121 to move vertically on the transmission component and selectively aligning them with the placement assembly 11. The stacking components 121 are used to place the battery cells 100 and can move the battery cells 100 to the placement assembly 11. This arrangement saves lateral space. In addition, after the battery cells 100 on the stacking components 121 have been transported, they can be replenished in a timely manner. The replenishment process does not affect the transport mechanism 3's transport of the battery cells 100 on the placement assembly 11, enabling continuous transport of the battery cells 100 by the transport mechanism 3 and improving work efficiency.
[0046] Specifically, the transmission drive is a rotary motor, and the transmission components include a mounting frame 122 and a conveyor belt. The rotary motor is connected to the conveyor belt for transmission. All stacking components 121 are fixed to the mounting frame 122 at intervals along the vertical direction. The mounting frame 122 is fixed to the conveyor belt, and the rotary motor enables the mounting frame 122 to move vertically on the conveyor belt. This configuration is simple and allows for long-distance transmission. Of course, the conveyor belt can be replaced with a chain.
[0047] Optionally, in this embodiment, the feeding mechanism 1 further includes a detection component 13. The detection component 13 is communicatively connected to the transmission drive and is used to detect whether the stacking component 121 and the placement assembly 11 are aligned. During the transmission of the stacking component 121, when the detection component 13 detects that any stacking component 121 is aligned with the placement assembly 11, the detection component 13 can stop the transmission drive, facilitating the stacking component 121 to move the battery cell 100 to the placement assembly 11. Specifically, the detection component 13 is a vision detection component, capable of high-precision detection.
[0048] Optionally, in this embodiment, as Figure 4As shown, the placement component 11 includes a fourth drive member and a first conveyor belt 111. The fourth drive member is tractively connected to the first conveyor belt 111, and the first conveyor belt 111 can drive the battery cells 100 to move. This configuration allows adjustment of the position of the battery cells 100 to meet the handling requirements of the conveying mechanism 3. Further, in this embodiment, the stacking component 121 includes a fifth drive member 1211 and a second conveyor belt 1212. The fifth drive member 1211 is tractively connected to the second conveyor belt 1212, and the second conveyor belt 1212 can drive the battery cells 100 to move. This configuration ensures that the conveying component 12 and the placement component 11 do not interfere with each other, while maintaining a simple structure and convenient transmission. Optionally, both the fourth drive member and the fifth drive member 1211 are rotary motors. Specifically, in this embodiment, the loading mechanism 1 also includes a positioning frame 14, on which four battery cells 100 are located. The first conveyor belt 111 and the second conveyor belt 1212 move the four battery cells 100 by moving the positioning frame 14.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
