Battery pack carrying bracket and transportation device

Abstract

The application discloses a battery pack bearing bracket and a conveying device. The battery pack bearing bracket comprises a lower layer rack and an upper layer rack. The lower layer rack comprises a lower rack main body and a first positioning plug. The upper layer rack comprises an upper rack main body and a first positioning hole. When one positioning is performed at a work station, the AGV drives the lower layer rack and the upper layer rack to ascend, so that the upper rack main body is supported on a work position of the work station. The AGV drives the lower layer rack to descend, so that the upper rack main body is separated from the lower rack main body in the vertical direction. The first positioning plug moves in the axial direction in the first positioning hole and is located in the first positioning hole. When secondary positioning is performed at the work station, the upper rack main body is offset relative to the lower rack main body under the driving of a secondary positioning driving element of the work position. The first positioning plug moves in the radial direction in the first positioning hole and is located in the first positioning hole. In this way, the AGV does not need to search for the docking position again, and the production efficiency is improved.

Description

Technical Field

[0001] This application relates to the field of automated battery pack production technology, and in particular to a battery pack support bracket and transport device. Background Technology

[0002] Currently, in the assembly of new energy battery packs, the industry generally uses AGVs to drive the battery pack carriers for process flow. The AGV roughly places the battery pack carrier at the workstation after a first positioning and then detaches. Subsequently, the secondary positioning drive at the workstation performs a secondary positioning calibration of the battery pack carrier. After the secondary positioning, the battery pack carrier will be offset relative to the AGV. The AGV needs to rescan the QR code and search for the position multiple times before it can be reconnected to the battery pack carrier, resulting in a significant decrease in production efficiency.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0030] The terms “length”, “width”, “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer”, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0031] Please refer to the following: Figures 1 to 3This embodiment discloses a transportation device, which includes a battery pack support bracket 100 and an AGV 200. The battery pack support bracket 100 includes a lower frame 10 and an upper frame 20. The lower frame 10 includes a lower frame body 11 and a first positioning pin 12. The lower frame body 11 can be used to support the AGV 200, and the first positioning pin 12 is disposed in the lower frame body 11. The upper frame 20 includes an upper frame body 21 and a first positioning insertion hole 22. The first positioning insertion hole 22 is disposed in the upper frame body 21, and the diameter of the first positioning insertion hole 22 is larger than the outer diameter of the first positioning pin 12. The length of the first positioning pin 12 is larger than the depth of the first positioning insertion hole 22. During transfer, the lower frame body 11 supports the AGV 200, the upper frame body 21 supports the lower frame body 11, and the first positioning pin 12 is inserted into the lower frame body 200. Insertion hole 22; During the first positioning at the workstation, the AGV200 drives the lower frame 10 and the upper frame 20 to rise, so that the upper frame body 21 is supported on the workstation position. The AGV200 drives the lower frame 10 to fall, so that the upper frame body 21 and the lower frame body 11 are separated in the vertical direction. The first positioning pin 12 moves axially in the first positioning insertion hole 22 and is located in the first positioning insertion hole 22. During the second positioning at the workstation, the upper frame body 21 is offset relative to the lower frame body 11 under the drive of the secondary positioning drive unit at the workstation (equivalent to the upper frame 20 performing secondary positioning alone). The first positioning pin 12 moves radially in the first positioning insertion hole 22 and is located in the first positioning insertion hole 22. With this design, when the AGV200 needs to transfer the battery pack carrier 100 and the battery pack for the next time, since the AGV200 remains connected to the lower frame 10, it does not need to find a new docking position. Furthermore, the lower frame 10 and the upper frame 20 are positioned via the first positioning pin 12 and the first positioning hole 22, eliminating the need for re-alignment. In other words, when the AGV200 needs to transfer the battery pack carrier 100 and the battery pack for the next time, the AGV200 rises... This allows the upper frame body 21 to be supported by the lower frame body 11 (equivalent to the battery pack support bracket 100 being offset relative to the AGV during secondary positioning at the workstation, which is converted into the upper frame 20 being offset relative to the lower frame 10; and due to the positioning effect of the first positioning pin 12 and the first positioning hole 22, the upper frame 20 and the lower frame 10 do not need to be re-aligned), avoiding the problem of the integral bracket AGV 200 needing to find a new docking position, thereby effectively improving production efficiency.

[0032] In addition, compared to the traditional method where the entire support bracket supports the workstation, the support bracket in this solution only supports the upper frame of the workstation, which can reduce the stress on the secondary positioning pins and extend their service life.

[0033] The primary and secondary positioning can be any positioning method available on the market, and are not specifically limited here. Specifically, the upper rack body 21 is also provided with a third positioning socket 23, and the secondary positioning drive is a third positioning pin, which is inserted into the third positioning socket 23 to perform secondary positioning on the upper rack 20.

[0034] In some embodiments, the projection of the outer periphery of the upper frame body 21 in the vertical direction is located outside the lower frame body 11, and the outer periphery of the upper frame body 21 is used to support the workstation. With this design, the outer periphery of the upper frame body 21 extends outward to form a supporting cantilever, allowing the workstation to directly support the upper frame 20, while the lower frame 10 does not contact the workstation, achieving true separation between the upper frame body 21 and the lower frame body 11, and ensuring that secondary positioning only acts on the upper frame 20.

[0035] It is understood that in other embodiments, embedded load-bearing, hook-type load-bearing, or slide rail-type load-bearing designs may be used instead of peripheral load-bearing designs, and these are not limited here.

[0036] In some embodiments, the lower frame body 11 is further provided with a first docking brush block 13 and a second docking brush block 14 electrically connected to each other, and the upper frame body 21 is further provided with a third docking brush block and an emergency stop button electrically connected to each other. When the lower frame body 11 is supported by the AGV 200, the first docking brush block 13 and the fourth docking brush block of the AGV 200 are in contact to achieve electrical connection. When the upper frame body 21 is supported by the lower frame body 11, the second docking brush block 14 and the third docking brush block are in contact to achieve electrical connection. When the emergency stop button is pressed, it sends a stop signal to the AGV 200. With this design, the docking brush blocks achieve layered electrical connection. The lower frame 10 is electrically connected to the AGV 200, and the upper frame 20 is electrically connected to the AGV 200 through the lower frame 10. The emergency stop button can cut off the circuit in time to ensure safety. The layered design of the overall electrical system facilitates maintenance.

[0037] It is understood that in other embodiments, plug-in connectors, wireless transmission, or slip ring connections may be used instead of the design of docking brush blocks, and this is not limited to these methods.

[0038] In some embodiments, the lower frame body 11 is also provided with a second positioning socket 15, which is adapted to the second positioning pin of the AGV200. With this design, the second positioning socket 15 cooperates with the second positioning pin of the AGV200 to achieve precise positioning of the lower frame body 11 and the AGV200, ensuring accurate and stable positioning of the AGV200 during lifting and transfer.

[0039] It is understood that in other embodiments, a positioning groove, a positioning pin, or a visual positioning method may be used instead of the design of the second positioning socket 15, and this is not limited here.

[0040] In addition, the lower frame body 11 is also equipped with a guide bar 16, which is adapted to the guide wheel of the workstation. The guide bar 16 and the guide wheel cooperate with each other to guide the secondary positioning. With this design, the guide bar 16 and the guide wheel cooperate to provide guidance for the upper frame body 21 to enter the workstation, reduce the positional deviation during secondary positioning, and improve positioning accuracy and efficiency.

[0041] It is understood that in other embodiments, tapered guides, inclined guides, or roller guides may be used instead of the design of guide bar 16, and this is not limited here.

[0042] In some embodiments, the upper frame body 21 is also provided with a support block 24 whose shape is adapted to the battery pack 300. The support block 24 is used to support the battery pack 300. With this design, the shape of the support block 24 matches the bottom of the battery pack 300, providing stable support, distributing the weight of the battery pack 300, and preventing damage caused by excessive local stress.

[0043] It is understood that in other embodiments, a support plate, support frame, or elastic support may be used instead of the support block 24, and this is not limited here.

[0044] Furthermore, the upper frame body 21 is also provided with a positioning block 25, which is located on the outer periphery of the support block 24 and is used to position the battery pack 300. With this design, the positioning block 25 forms a limit on the outer periphery of the support block 24, preventing the battery pack 300 from shifting or shaking during the transfer process, and ensuring the stability of the battery pack 300 position.

[0045] It is understood that in other embodiments, a positioning pin, a retaining edge, or a clamping mechanism may be used instead of the positioning block 25, and this is not limited here.

[0046] Furthermore, the upper frame body 21 is also provided with a fourth positioning pin 26, which is located on the outer periphery of the support block 24 and is used to insert into the fourth positioning socket of the battery pack 300. With this design, the fourth positioning pin 26 cooperates with the fourth positioning socket of the battery pack 300 to achieve precise positioning of the battery pack 300 and the upper frame body 21, ensuring that the battery pack 300 is installed in an accurate position.

[0047] It is understood that in other embodiments, positioning protrusions, snaps, or magnetic adsorption may be used instead of the design of the fourth positioning pin 26, and this is not limited here.

[0048] In some embodiments, the bottom of the lower frame body 11 is provided with casters 17. With this design, the casters 17 facilitate the movement and adjustment of the lower frame body 11 on the ground or on the AGV200, improving the flexibility and operability of the equipment.

[0049] It is understood that in other embodiments, directional wheels, casters, or sliders may be used instead of the universal wheel 17, and this is not limited here.

[0050] The transportation device provided in this application includes a battery pack support bracket 100 comprising a lower frame 10 and an upper frame 20. The lower frame 10 includes a lower frame body 11 and a first positioning pin 12. The lower frame body 11 can be used to support an AGV 200, and the first positioning pin 12 is disposed on the lower frame body 11. The upper frame 20 includes an upper frame body 21 and a first positioning hole 22 adapted to the first positioning pin 12. During transfer, the lower frame body 11 supports the AGV 200, the upper frame body 21 supports the lower frame body 11, and the first positioning pin 12 is inserted into the first positioning hole 22. At the workstation, the lower frame body 11 supports the AGV 200, the upper frame body 21 is separated from the lower frame body 11 in the vertical direction, and the first positioning pin 12 is inserted into the first positioning hole 22. The upper frame body 21 supports the workstation position. With this design, the upper frame 20 and the lower frame 10 can be partially separated in the vertical direction, so that the AGV200 is always connected to the lower frame 10 and does not detach. The lower frame 10 and the upper frame 20 are maintained in a positioning connection state through the first positioning pin 12 and the first positioning hole 22. The upper frame 20 is positioned separately, avoiding the problem that the AGV200 needs to find a docking position again after the integral bearing bracket is positioned twice, thus improving production efficiency.
