Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to battery loading into a cabinet, specifically to a pack loading AGV adjustment and rotation mechanism. Background Technology

[0002] A battery pack (PACK) refers to a finished battery assembly made by combining multiple individual battery cells in a specific series-parallel configuration, adding protection circuit modules, a battery management system (BMS), and other necessary supporting equipment, and finally packaging, encapsulating, and assembling them. It is a crucial process in the production of power batteries and the energy source for electric vehicles and other devices.

[0003] There are three traditional methods for installing battery packs in storage cabinets: One method involves manually lifting the batteries with a forklift and pushing them into the cabinet. This is time-consuming and labor-intensive, and the small gap between the battery and the battery compartment makes forklift adjustments insensitive and difficult to align, resulting in low efficiency. Another method uses a robotic arm and a battery loading platform. However, the robotic arm is limited to lightweight batteries and requires fixing to a platform with guide rails, limiting its application to certain areas. While the third method, AGV loading, offers some flexibility and can adapt to production changes, existing AGVs lack precision in adjusting the battery pack's angle, significantly increasing the time required for AGV rotation and positioning, thus reducing loading efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pack-in-cabinet AGV adjustment and rotation mechanism, which overcomes the deficiencies of existing technologies, is reasonably designed, and can effectively save the time of AGV body rotation and positioning, thereby improving the efficiency of AGV automatic cabinet entry.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pack-in-cabinet AGV adjustment and rotation mechanism includes a rotary base plate and a servo motor. The rotary base plate is fixedly installed on the lower surface of the adjustment platform, and the servo motor is fixedly installed on the vehicle body. A rotary bearing is provided below the rotary base plate, and a hollow ring is provided in the middle of the rotary base plate. The inner ring of the rotary bearing is fixedly connected to the hollow ring, and an internal gear ring is fixedly installed on the inner surface of the inner ring of the rotary bearing. The output end of the servo motor is connected to the input end of a planetary reducer, and a pinion is fixedly installed on the output end of the planetary reducer. The pinion meshes with the internal gear ring, and the upper part of the planetary reducer is connected to the outer ring of the rotary bearing.

[0007] Preferably, a limit block is fixedly installed on the inner ring of the slewing bearing, and a proximity switch is fixedly installed on the end face of the pinion, the proximity switch being in contact with the limit block.

[0008] Preferably, the lower surface of the outer ring of the slewing bearing is provided with a plurality of threaded holes evenly distributed, and a connecting plate is installed on the top of the end cover of the planetary reducer. The connecting plate is connected to the threaded holes by bolts.

[0009] Preferably, a right-angle plate is fixedly installed on the side of the planetary reducer, and the right-angle plate is fixedly installed on the vehicle body.

[0010] This invention provides a pack-loading AGV adjustment and rotation mechanism. It offers the following advantages: By controlling the output shaft of a servo motor to rotate, a pinion gear is driven to rotate. Through the meshing of the pinion gear and the internal gear ring, the rotating base plate is driven to rotate, thus achieving a 0-180° rotation of the entire adjustment platform in the horizontal plane. Furthermore, the servo motor allows for precise control of the platform's rotation angle. This significantly reduces the time spent on AGV body rotation and positioning, thereby improving the efficiency of AGV automated loading. The entire process is completely manual, greatly reducing labor intensity. It is not limited by the carrying capacity or area of ​​the robotic arm and is suitable for various types and weights of battery packs. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] Example 1, as Figure 1-3 As shown, a pack-in-cabinet AGV adjustment and rotation mechanism includes a rotary base plate 1 and a servo motor 2. The rotary base plate 1 is fixedly installed on the lower surface of the adjustment platform, and the servo motor 2 is fixedly installed on the body of the AGV trolley. A rotary bearing 3 is provided below the rotary base plate 1, and a hollow ring is provided in the middle of the rotary base plate 1. The inner ring of the rotary bearing 3 is fixedly connected to the inner wall of the hollow ring, and an internal gear ring 4 is fixedly installed on the inner surface of the inner ring of the rotary bearing 3. The output end of the servo motor 2 is connected to the input end of a planetary reducer 5. A pinion 6 is fixedly installed on the output end of the planetary reducer 5, and the pinion 6 meshes with the internal gear ring 4. Multiple threaded holes 9 are evenly provided on the lower surface of the outer ring of the rotary bearing 3. A connecting plate 10 is installed on the top of the end cover of the planetary reducer 5, and the connecting plate 10 is connected to the threaded holes 9 of the outer ring of the rotary bearing 3 by bolts.

[0019] Working principle:

[0020] In operation, the AGV vehicle body is first moved to the corresponding position. Then, the output shaft of the servo motor 2 is rotated, which drives the small gear 6 to rotate through the planetary reducer 5. The meshing between the small gear 6 and the internal gear ring 4 causes the internal gear ring 4 to rotate. Since the planetary reducer 5 and the rotary base plate 1 are respectively connected to the outer and inner rings of the rotary bearing 3, the meshing between the small gear 6 and the internal gear ring 4 causes the outer and inner rings of the rotary bearing 3 to rotate relative to each other. This, in turn, causes the rotary base plate 1 to rotate. The rotation of the rotary base plate 1 then causes the adjustment platform to rotate, aligning the input end of the adjustment platform with the output direction of the battery pack. Thus, the vehicle body itself does not need to rotate to achieve the task of receiving battery packs at different angles.

[0021] Similarly, when it is necessary to put the battery pack into the cabinet, the AGV can be moved to the corresponding position again, and the output shaft of the servo motor 2 can be rotated to drive the pinion 6 to rotate. Through the meshing between the pinion 6 and the internal gear ring 4, the rotary base plate 1 can be rotated, which in turn drives the adjustment platform to rotate, so that the entrance end of the adjustment platform corresponds to the direction of the battery pack PACK entering the cabinet; thus realizing the rapid cabinet entry of the battery pack PACK.

[0022] The entire process only requires controlling the output shaft of servo motor 2 to rotate, thereby achieving a 0-180° rotation of the entire adjustment platform in the horizontal plane. The servo motor 2 also enables precise control of the platform's rotation angle. This significantly reduces the time spent on AGV body rotation and positioning, improving AGV automated cabinet entry efficiency. Furthermore, the entire process is completely human-operated, greatly reducing manual labor intensity. It is not limited by the robotic arm's load-bearing capacity or area constraints, and is suitable for various types and weights of battery packs.

[0023] In Example 2, as a further preferred embodiment of Example 1, a limit block 7 is fixedly installed on the inner ring of the slewing bearing 3, and a proximity switch 8 is fixedly installed on the end face of the pinion 6. The sensing end of the proximity switch 8 cooperates with the limit block 7. In this embodiment, the signal output end of the proximity switch 8 is connected to the signal input end of the servo motor 2 through a control circuit. Thus, when the limit block 7 of the inner ring of the slewing bearing 3 rotates to a position close to the proximity switch 8, a signal can be transmitted to the control circuit through the signal output end of the proximity switch 8. The control circuit then controls the servo motor 2 to reverse or stop operating. Thus, through the cooperation of the proximity switch 8 and the limit block 7, the rotation angle and position of the slewing base plate 1 are effectively limited, thereby ensuring the accuracy of the rotation of the slewing base plate 1.

[0024] In embodiment three, as a further preferred embodiment one, a right-angle plate 11 is fixedly mounted on the side of the planetary reducer 5, and the right-angle plate 11 is fixedly mounted on the vehicle body. The right-angle plate 11 ensures the stability of the entire servo motor 2 and planetary reducer 5 installation.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
