[0001] This utility model relates to the field of heavy-duty truck AGV battery swapping technology, and in particular to an automatic battery-loading device for new energy truck AGVs. Background Technology

[0002] With the popularization of new energy batteries, the number of electric trucks is gradually increasing. The power battery of new energy trucks is installed at the bottom of the longitudinal beam of the frame, between the front axle and the middle axle. It consists of 3 batteries and a battery frame assembly. The battery cell weighs 1.2T. Tools are needed to insert the battery into the frame and then lift or assemble it. It also needs to meet the current production cycle of new energy battery swapping models.

[0003] In existing technologies, forklifts are commonly used to lift batteries. Specifically, a forklift is used to lift a pallet containing a battery, align the battery with the battery mounting slot, make small adjustments, lift the battery upwards and insert it into the slot, and then a person uses an electric drill to reach the bottom of the battery and tighten the screws. This method is inefficient, labor-intensive, and carries significant safety risks. To improve material flow efficiency, there is an urgent need for new battery swapping devices to assist in battery installation. Utility Model Content

[0004] In view of this, the present invention provides an automatic battery installation device for new energy truck AGVs to solve the technical problem of low battery installation efficiency in the prior art.

[0005] An embodiment of this utility model provides an automatic battery installation device for new energy truck AGVs, used for power battery installation, comprising:

[0006] An AGV stacking platform with grooves on its upper surface;

[0007] A floating plate, which is floatingly disposed within the groove;

[0008] Multiple positioning mechanisms are disposed within the groove. Each positioning mechanism includes an electric cylinder, a horizontal wedge block, and a vertical wedge block. The movable end of the electric cylinder is connected to the horizontal wedge block. The horizontal wedge block abuts against one wedge surface of the vertical wedge block, and the other wedge surface of the vertical wedge block can abut against the edge of the floating plate. The vertical wedge block can slide vertically within the groove.

[0009] The system includes multiple electric wrenches, which are vertically movable and positioned below the AGV stacking platform. Each electric wrench can extend upward into the groove. The AGV stacking platform itself lifts the power battery placed on the floating plate. The floating plate is levitally connected to the AGV stacking platform, allowing the non-removable hexagonal screws placed around the power battery to flexibly contact the truck mounting holes. The multiple electric wrenches extend upward beyond the floating plate to contact the corresponding hexagonal screws and drive them to rotate and tighten, thus completing the installation of the power battery.

[0010] Furthermore, the AGV stacking platform is provided with multiple rolling grooves, and a ball is rotatably disposed in each rolling groove. The floating plate contacts the multiple balls to float and connect to the AGV stacking platform.

[0011] Furthermore, the inner wall of the groove is provided with multiple mounting slots for the positioning mechanism and through slots for the movement of multiple electric wrenches, and a vertical wedge block is vertically slidably connected to a mounting slot.

[0012] Furthermore, each of the through slots is provided with a linear module via a bracket, and each of the electric wrenches is connected to the movable end of one of the linear modules.

[0013] Furthermore, it also includes a hidden AGV, a lifting forklift device, and a towing AGV. The towing AGV is movably connected to the lifting forklift device for towing new energy trucks, and the hidden AGV is located at the bottom of the AGV stacking platform.

[0014] Furthermore, the AGV stacking platform is equipped with at least two vision cameras, which are distributed diagonally along the AGV stacking platform.

[0015] Furthermore, the edge of the AGV stacking platform is provided with multiple guide blocks, and the side of the guide block facing the center of the AGV stacking platform is an inclined surface facing downward.

[0016] Furthermore, the height of the guide block is greater than the height of the vision camera to prevent the power battery from contacting the vision camera.

[0017] Furthermore, the plurality of rolling grooves and the plurality of balls are arranged in a rectangular array within the groove, and the rolling grooves give way to the through groove and the mounting groove.

[0018] Furthermore, the area of ​​the floating plate is smaller than the bottom area of ​​the power battery, so that the electric wrench can contact the internal hex screws of the power battery.

[0019] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The automatic battery installation device for new energy trucks using AGVs of this utility model effectively improves the automation level of power battery installation by adopting the coordinated work of an AGV stacking platform, a floating plate, a positioning mechanism, and an electric wrench, reducing manual operation, significantly improving work efficiency, and reducing labor intensity; the electric cylinder drives the horizontal wedge block and the vertical wedge block to cooperate, which can accurately position the power battery and ensure that the installation position is accurate, greatly improving the installation accuracy and reliability; the design of the floating plate allows the power battery to be finely adjusted during contact installation, avoiding hard contact of screws, increasing the versatility and flexibility of the device; in addition, the electric wrench, through the precise control of the linear module, can stably tighten the internal hex screws, ensuring the firmness of the installation, while avoiding the problem of uneven tightening torque that may be caused by traditional manual tools.

The content protected by this utility model does not involve any improvement to the internal structure and method.

[0032] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components.

[0033] Please refer to Figure 2 The present invention provides an automatic battery loading device for a new energy truck AGV, including an AGV stacking platform 5, a floating plate 8, multiple positioning mechanisms 13 and multiple electric wrenches 10.

[0034] Example 1: Please refer to Figure 3 and Figure 4 The AGV stacking platform 5 is the supporting foundation of the entire device. A groove 51 is provided on its upper surface. The floating plate 8 is floatingly set in the groove 51 and is connected to the AGV stacking platform 5 by multiple balls 7.

[0035] Specifically, the AGV stacking platform 5 is provided with multiple rolling grooves 52, and a ball bearing 7 is provided in each rolling groove 52. The floating plate 8 contacts multiple balls bearing 7, so that it can float horizontally within the groove 51 to adapt to the slight positional deviation when the power battery 6 is placed, thereby improving the flexibility and accuracy of installation.

[0036] In this embodiment, multiple positioning mechanisms 13 are disposed in the groove 51. Each positioning mechanism 13 includes an electric cylinder 131, a horizontal wedge block 132, and a vertical wedge block 133. The movable end of the electric cylinder 131 is connected to the horizontal wedge block 132. The horizontal wedge block 132 abuts against one wedge surface of the vertical wedge block 133. The other wedge surface of the vertical wedge block 133 can abut against the edge of the floating plate 8. The vertical wedge block 133 can slide vertically in the groove 51.

[0037] Furthermore, the inner wall of the groove 51 is provided with a plurality of mounting slots 54 for the positioning mechanism 13 to be installed. Each vertical wedge block 133 is vertically slidably connected to the corresponding mounting slot 54. The mounting slot 54 is L-shaped, extending from the bottom wall of the groove 51 to the side wall of the groove 51. The electric cylinder 131 and the horizontal wedge block 132 are housed in the horizontal part of the mounting slot 54. The horizontal wedge block 132 can slide in the horizontal section of the mounting slot 54, while the vertical wedge block 133 is slidably connected to the vertical section of the mounting slot 54 so as to be able to move in the vertical direction.

[0038] In the specific implementation process, since the floating plate 8 is supported in the groove 51 by multiple balls 7, the vertical wedge block 133 will contact the floating plate 8 during its upward movement. The upper end of the vertical wedge block 133 is a wedge-shaped surface. Through the contact between the wedge-shaped surfaces of multiple vertical wedge blocks 133 and the edge of the floating plate 8, the floating plate 8 can achieve automatic centering. At this time, the floating plate 8 is stably supported by multiple vertical wedge blocks 133, so that the relative position of the power battery 6 and the floating plate 8 can be more determined when the power battery 6 is placed on the floating plate 8.

[0039] By controlling the extension and retraction of the electric cylinder 131, the horizontal wedge block 132 can be driven to move, thereby squeezing the vertical wedge block 133 to move up and down, thereby positioning and clamping the edge of the floating plate 8, ensuring the stability and accuracy of the power battery 6 during placement.

[0040] Example 2: Please refer to Figure 3 and Figure 4Multiple electric wrenches 10 are vertically movable and can be installed under the AGV stacking platform 5. They can all extend upward into the groove 51. A through groove 53 is provided on the inner wall of the groove 51 to allow the electric wrenches 10 to move. A linear module 9 is provided in each through groove 53 through a bracket. Each electric wrench 10 is connected to the movable end of the corresponding linear module 9. The linear module 9 can drive the electric wrench 10 to move up and down precisely so that it can accurately contact the hexagonal screws on the power battery 6 and perform the tightening operation.

[0041] Please see Figure 1 The device also includes a hidden AGV4, a lifting forklift device 1, and a traction AGV2. The traction AGV2 is movably connected to the lifting forklift device 1 and is used to tow the new energy truck 3 to the designated installation position. The hidden AGV4 is set at the bottom of the AGV stacking platform 5 and can drive the AGV stacking platform 5 to move, realizing the flexible transfer of the entire device between different work stations and improving work efficiency.

[0042] To improve positioning accuracy and automation during installation, at least two vision cameras 11 are installed on the AGV stacking platform 5, and the two vision cameras 11 are distributed diagonally along the AGV stacking platform 5.

[0043] The vision camera 11 can identify and locate the positions of the power battery 6 and the truck mounting holes, providing accurate coordinate information for subsequent installation operations. Meanwhile, multiple guide blocks 12 are provided at the edge of the AGV stacking platform 5. The side of the guide block 12 facing the center of the AGV stacking platform 5 is a downward-facing slope, which can guide the power battery 6 to be accurately placed on the floating plate 8 and prevent it from shifting during placement.

[0044] It should be noted that the height of the guide block 12 is greater than the height of the vision camera 11, which can effectively prevent the power battery 6 from contacting the vision camera 11 and protect the vision camera 11 from damage.

[0045] In this embodiment, multiple rolling grooves 52 and multiple balls 7 are arranged in a rectangular array within the groove 51, and the rolling grooves 52 give way to the through groove 53 and the mounting groove 54, ensuring that the components are reasonably arranged and do not interfere with each other, while ensuring the stability and flexibility of the floating plate 8.

[0046] The area of ​​the floating plate 8 is smaller than the bottom area of ​​the power battery 6. This design is intended to allow the electric wrench 10 to smoothly contact the internal hex screws on the power battery 6, ensuring a smooth installation operation.

[0047] In actual use, the new energy truck 3 is first towed onto the lifting forklift device 1 by the traction AGV2. Then, the lifting forklift device 1 lifts the new energy truck 3 to a suitable height. The lurking AGV4 drives the AGV stacking platform 5 to move to the designated installation position. At this time, the control cylinder 131 works, driving the horizontal wedge block 132 to move, which in turn drives the vertical wedge block 133 to move up and down, centering and clamping the edge of the floating plate 8 to ensure the stability of the floating plate 8. The power battery 6 is then placed on the floating plate 8 by hoisting. Guided by the guide block 12, the power battery 6 is accurately placed. Then, the vision camera 11 monitors the power battery 6 and the truck. The mounting hole positions are identified and located, and the electric cylinder 131 is stopped again. At this time, the floating plate 8 falls down to contact multiple ball bearings 7 and floats to connect with the AGV stacking platform 5. The power battery 6 can be placed on the floating plate 8 and move slightly left and right. At the same time, the AGV stacking platform 5 lifts itself, causing the power battery 6 on the floating plate 8 to move upward, so that the hexagonal screws around the power battery 6 are aligned with the mounting holes on the truck and make flexible contact. Then, the linear module 9 drives the electric wrench 10 to move upward, pass through the corresponding position on the floating plate 8, and contact the hexagonal screws on the power battery 6. The electric wrench 10 drives the hexagonal screws to rotate and tighten, completing the installation of the power battery 6.

[0048] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0049] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
