Description

Technical Field

[0001] This utility model relates to the field of battery cell transportation technology, and in particular to a battery cell transportation device. Background Technology

[0002] When photovoltaic module cells are produced in strings, the cells need to be loaded first and transported to the required location. Then, the solder ribbon is positioned on the cells so that the solder ribbon coincides with the grid lines on the surface of the cells.

[0003] Before transporting the solar cells to the cell-to-strip bonding station, a precise positioning process is required to ensure the accuracy of the cell's position. After precise positioning, the cells are then moved to the bonding station. Current technology typically positions two-piece solar cells (comprising two quarter-piece cells), but this method can only position one quarter-piece cell at a time, resulting in low processing efficiency, slower production cycle, and increased production costs for solar cell strings. Utility Model Content

[0004] The purpose of this invention is to provide a battery cell transport device that can simultaneously align two battery cells, thereby accelerating the positioning efficiency of the battery cells, speeding up the production cycle, and reducing the production cost of battery strings.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A battery cell transport device includes a positioning mechanism. The positioning mechanism includes a first driving component, a first alignment component, and two sets of second alignment components. The first alignment component can abut against one side of each battery cell along a first direction. The second alignment components can abut against one side of the battery cell along a second direction. The two sets of second alignment components can abut against the two opposite sides of two battery cells respectively. The second direction is perpendicular to the first direction. The first driving component is used to drive the first alignment component and the two sets of second alignment components to synchronously abut against the corresponding two battery cells.

[0007] In some possible implementations, the cell transport device further includes a conveying mechanism comprising a second drive assembly and a conveyor belt. The second drive assembly drives the conveyor belt to move, thereby moving the cell along the first direction. A first alignment assembly is disposed opposite to the conveyor belt and abuts against a first position of the cell. Two sets of the first alignment assemblies are located on opposite sides of the conveyor belt along a second direction. The second alignment assembly abuts against a second position of the cell. The first position is located on the side of the axis of symmetry of the cell extending along the first direction away from the second position.

[0008] In some possible implementations, the first driving component includes a first driving member and two inclined slide rails arranged in a mirror image. The first driving member is used to drive the first correction component to move along the first direction. The two inclined slide rails are arranged in a one-to-one correspondence with the two second correction components. Each second correction component is slidably connected to the corresponding inclined slide rail and is movably disposed on the first correction component. When the first correction component moves along the first direction, the first correction component can drive the two sets of second correction components to slide on the corresponding inclined slide rails.

[0009] In some possible implementations, the first correction component includes a synchronizing element fixed to the output end of the first drive component. The synchronizing element has two slide grooves arranged in a mirror image. The two slide grooves are arranged one-to-one with the two second correction components and one-to-one with the two inclined slide rails. Each second correction component is slidably connected to the corresponding slide groove, and the extension direction of each slide groove is mirrored with the extension direction of the corresponding inclined slide rail relative to the second direction.

[0010] In some possible implementations, both the first and second correction components include a correction hand, which includes a first connector and a rotating member. The rotating member is rotatable relative to the first connector and can abut against the battery cell.

[0011] In some possible implementations, the corrector may further include a second connector and a micrometer, the micrometer being disposed on the second connector and the measuring end of the micrometer being connected to the first connector.

[0012] In some possible implementations, the battery cell transport device further includes a handling mechanism for gripping the battery cell at the positioning mechanism and moving the battery cell along the second direction.

[0013] In some possible implementations, the conveying mechanism includes a second drive, an adjustment assembly, and two grippers. The output end of the second drive is connected to the adjustment assembly, and the two grippers are spaced apart along the second direction and are both connected to the output end of the adjustment assembly. The output end of the adjustment assembly is used to adjust the relative position of the two grippers.

[0014] In some possible implementations, the pitch adjustment assembly includes a third drive member and a lead screw, the threads at both ends of the lead screw having opposite directions, and the two gripper hands being threadedly connected to the two ends of the lead screw respectively; the output end of the third drive member is drivenly connected to the lead screw, and is used to drive the two gripper hands to move in a direction closer to or further away from each other.

[0015] In some possible implementations, the cell transport device further includes a detection mechanism and a waste cell recycling frame. The detection mechanism is used to detect whether the cells at the positioning mechanism are defective, and the transport mechanism can move the defective cells to the waste cell recycling frame and release them into the waste cell recycling frame.

[0016] The beneficial effects of this utility model are:

[0017] The battery cell transport device provided by this utility model includes a positioning mechanism, which comprises a first driving component, a first alignment component, and two sets of second alignment components. When the first driving component drives the first alignment component and the two sets of second alignment components to move, the first alignment component abuts against the opposite side of each battery cell along a first direction, and the second alignment component abuts against the opposite side of each battery cell along a second direction. The two sets of second alignment components abut against the opposite sides of the two battery cells respectively. During this process, the first alignment component and the two sets of second alignment components can achieve the alignment of the two battery cells. Furthermore, the first driving component can drive the first alignment component and the two sets of second alignment components to simultaneously abut against the corresponding two battery cells. This configuration enables simultaneous alignment of the two battery cells, accelerating the positioning efficiency of the battery cells, thereby speeding up the production cycle and reducing the production cost of the battery string.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] like Figures 1 to 6 As shown, this utility model provides a battery cell transport device, including a positioning mechanism 1. The positioning mechanism 1 includes a first driving component 11, a first alignment component 12, and two sets of second alignment components 13. The first alignment component 12 can abut against the opposite side of each battery cell 100 along a first direction. The second alignment component 13 can abut against the opposite side of the battery cell 100 along a second direction, and the two sets of second alignment components 13 can respectively abut against the mutually distant sides of two battery cells 100. The second direction is perpendicular to the first direction. Specifically, the first direction is... Figures 1 to 3 In the diagram, the X direction is the length direction of the battery cell 100, and the Y direction is the width direction of the battery cell 100. The first driving component 11 is used to drive the first alignment component 12 and the two sets of second alignment components 13 to synchronously abut against the corresponding two battery cells 100. When the first driving component 11 drives the first alignment component 12 and the two sets of second alignment components 13 to move, the first alignment component 12 abuts against the side of each battery cell 100 opposite to the first direction, and the second alignment component 13 abuts against the side of the battery cell 100 opposite to the second direction. The two sets of second alignment components 13 abut against the two sides of the two battery cells 100 that are far apart from each other, respectively. In this process, the alignment of the two battery cells 100 can be achieved through the first alignment component 12 and the two sets of second alignment components 13. Based on this, the first drive component 11 can drive the first alignment component 12 and two sets of second alignment components 13 to synchronously contact the corresponding two battery cells 100. With this configuration, the two battery cells 100 can be aligned at the same time, which speeds up the positioning efficiency of the battery cells 100, thereby speeding up the production cycle and reducing the production cost of the battery string.

[0035] Optionally, in this embodiment, as Figure 1 and Figure 2As shown, the battery cell transport device also includes a conveying mechanism 2, which includes a second drive assembly and a conveyor belt 21. The second drive assembly drives the conveyor belt 21 to move, thereby moving the battery cell 100 along the conveyor belt 21 in a first direction. A first alignment assembly 12 is arranged opposite to the conveyor belt 21 and abuts against a first position of the battery cell 100. Two sets of first alignment assemblies 12 are located on opposite sides of the conveyor belt 21 along a second direction. A second alignment assembly 13 abuts against a second position of the battery cell 100. The first position is located on the side of the axis of symmetry of the battery cell 100 extending along the first direction away from the second position. Arranging the first alignment assembly 12 opposite to the conveyor belt 21 allows the battery cell 100 to move along the first direction until it abuts against the first alignment assembly 12. In this embodiment, the axis of symmetry of the battery cell 100 extending along the first direction is the axis of symmetry of the battery cell 100 extending along its length direction, such as... Figure 2 As shown, the first position is located to the right of the axis of symmetry extending along the length of the battery cell 100, so that when the battery cell 100 comes into contact with the first alignment component 12, it will shift towards the direction of the second alignment component 13 under the combined action of the friction force of the conveyor belt 21 and the contact force of the first alignment component 12. This facilitates the joint action of the first alignment component 12 and the second alignment component 13 to align the battery cell 100, resulting in a better alignment effect.

[0036] Optionally, in this embodiment, as Figure 3 As shown, the first driving assembly 11 includes a first driving member 111 and two mirror-arranged inclined slide rails 112. The first driving member 111 drives the first alignment assembly 12 to move along a first direction. The two inclined slide rails 112 are correspondingly arranged with two second alignment assemblies 13. Each second alignment assembly 13 is slidably connected to its corresponding inclined slide rail 112 and is movably disposed on the first alignment assembly 12. When the first alignment assembly 12 moves along the first direction, it can drive the two sets of second alignment assemblies 13 to slide on their respective inclined slide rails 112. This arrangement is simple in structure and convenient in operation, and can achieve synchronous contact between the first alignment assembly 12 and the two sets of second alignment assemblies 13 and the corresponding two battery cells 100. When the first driving member 111 moves the first alignment component 12 toward the conveyor belt 21, it causes the two sets of second alignment components 13 to move closer to each other, positioning the battery cell 100; when the first driving member 111 moves the first alignment component 12 away from the conveyor belt 21, it causes the two sets of second alignment components 13 to move further apart. Optionally, the first driving member 111 is a linear motor or a hydraulic cylinder, or the first driving member 111 is a rotary motor, which drives the first alignment component 12 to move along the first direction through a connecting screw and nut mechanism.

[0037] Optionally, in this embodiment, as Figure 3 and Figure 4As shown, the first alignment component 12 includes a synchronizing element 121, which is fixed to the output end of the first driving element 111. The synchronizing element 121 has two mirror-shaped sliding grooves 1211, which correspond one-to-one with the two second alignment components 13 and one-to-one with the two inclined slide rails 112. Each second alignment component 13 is slidably connected to its corresponding sliding groove 1211, and the extension direction of each sliding groove 1211 is mirror-image of the extension direction of the corresponding inclined slide rail 112 relative to a second direction. With this configuration, the synchronizing element 121 drives the two second alignment components 13 to move synchronously through the two sliding grooves 1211, while preventing interference between the second alignment components 13 and the synchronizing element 121 when sliding on the inclined slide rails 112. The mirror-image of the extension direction of each sliding groove 1211 and the extension direction of the corresponding inclined slide rail 112 relative to a second direction makes the sliding of the second alignment components 13 on the inclined slide rails 112 more flexible and improves work efficiency. Furthermore, in this embodiment, the first drive assembly 11 also includes at least one positive slide rail 113, which extends along a first direction, and the synchronizing member 121 is slidably connected to the positive slide rail 113. This arrangement ensures the smooth movement of the synchronizing member 121.

[0038] Optionally, in this embodiment, as Figure 2 As shown, both the first alignment component 12 and the second alignment component 13 include an alignment handle 14. The alignment handle 14 includes a first connecting member 141 and a rotating member 142. The rotating member 142 can rotate relative to the first connecting member 141 and can abut against the battery cell 100. This configuration allows the rotating member 142 to rotate relative to the first connecting member 141, preventing damage to the battery cell 100 when the alignment handle 14 abuts against it. Optionally, the rotating member 142 can be a bearing for more flexible rotation.

[0039] Optionally, in this embodiment, the alignment tool 14 further includes a second connector 143 and a micrometer 144. The micrometer 144 is disposed on the second connector 143, and the measuring end of the micrometer 144 is connected to the first connector 141. Specifically, one end of the first connector 141 is threadedly fixedly connected to the measuring end of the micrometer 144. Before positioning and aligning the two battery cells 100, the position of the rotating member 142 can be initially adjusted using the micrometer 144 to ensure positioning accuracy.

[0040] Optionally, in this embodiment, the first alignment component 12 includes two alignment handles 14, which respectively abut against two battery cells 100. The two second connecting members 143 corresponding to the two alignment handles 14 are fixed to a first base 122, which is connected to a synchronization member 121. The two second connecting members 143 corresponding to the two alignment handles 14 are integrally formed. Furthermore, each second alignment component 13 includes two alignment handles 14, which abut against the same battery cell 100. The two second connecting members 143 corresponding to the two alignment handles 14 are fixed to a second base 131, which is slidably connected to an inclined slide rail 112. The two second connecting members 143 corresponding to the two alignment handles 14 are integrally formed.

[0041] Optionally, in this embodiment, the battery cell transport device further includes a transport mechanism 3, which is used to grasp the battery cell 100 at the positioning mechanism 1 and move the battery cell 100 along the second direction. By setting the transport mechanism 3, the positioned and corrected battery cell 100 can be moved along the second direction to the battery cell and welding strip bonding station.

[0042] Furthermore, the conveying mechanism 3 includes a second drive unit, a spacing adjustment assembly, and two grippers 31. The output end of the second drive unit is connected to the spacing adjustment assembly and is used to move the spacing adjustment assembly along a second direction. The two grippers 31 are spaced apart along the second direction and are both connected to the output end of the spacing adjustment assembly. The output end of the spacing adjustment assembly is used to adjust the relative position of the two grippers 31. The two grippers 31 are used to grip two battery cells 100 respectively. This arrangement separates the two battery cells 100 during transport, thereby making the spacing between the battery cells 100 more closely match the placement position of the battery cells 100 in the battery cell and welding strip bonding station. Specifically, the second drive unit is a linear motor. In addition, the conveying mechanism 3 also includes a guide 33, and the spacing adjustment assembly is slidably connected to the guide 33. Specifically, the guide 33 is a slide rail. In this embodiment, the bottom end of the gripper 31 is provided with a vacuum nozzle 311 for adsorbing or releasing the battery cells 100.

[0043] Optionally, in this embodiment, the pitch adjustment assembly includes a third drive member and a lead screw 32. The threads at both ends of the lead screw 32 are in opposite directions, and two gripper hands 31 are respectively threaded to both ends of the lead screw 32. The output end of the third drive member is connected to the lead screw 32 for driving the two gripper hands 31 to move closer to or further away from each other. This configuration facilitates adjustment of the distance between the two gripper hands 31 with high precision. Specifically, the third drive member is a rotary motor.

[0044] Optionally, in this embodiment, the battery cell transport device further includes a detection mechanism 4 and a waste cell recycling frame 5. The detection mechanism 4 is used to detect whether there are defects in the battery cells 100 at the positioning mechanism 1. The transport mechanism 3 can move the defective battery cells 100 to the waste cell recycling frame 5 and release them into the waste cell recycling frame 5. This configuration facilitates the recycling of defective battery cells 100. Specifically, the detection mechanism 4 is a vision inspection module, which can achieve high-precision detection.

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.
