Description

Technical Field

[0001] This utility model relates to the field of industrial automation, and in particular to a high-power wireless charging coil automatic alignment robotic arm. Background Technology

[0002] The high-power wireless charging coil automatic alignment robotic arm is a device used to automatically align the transmitting coil and receiving coil during the wireless charging process of AGVs. It is now widely used in AGV systems with high-power wireless charging technology, such as in industrial automated production workshops and intelligent warehousing and logistics centers.

[0003] Existing high-power wireless charging coil-aligning robotic arms cannot be applied to multiple planes. During charging, the AGV often needs to make adjustments in multiple directions, which is time-consuming and laborious, and will also increase the charging time, thereby reducing efficiency. Utility Model Content

[0004] To overcome the shortcomings of existing technologies that cannot be applied to multiple planes, the technical problem is to provide a high-power wireless charging coil that can automatically adjust its angle and align with the robotic arm.

[0005] The technical solution is as follows: A high-power wireless charging coil automatic alignment robotic arm includes a control box. A support block and an electric push rod A are fixedly connected on the left side of the control box. Fixed plates are slidably connected to the upper and lower sides of the support block. The telescopic rod of the electric push rod A is fixedly connected to the fixed plates. A driving block is rotatably connected between the two fixed plates. The driving block can rotate between the fixed plates to change the angle and at the same time support the wireless charging module. The front-facing side of the driving block is fixedly connected to the wireless charging module.

[0006] In one embodiment, a positioning frame is also included. The left side of the control box is fixedly connected to the positioning frame and slidably connected to the rack. The right end of the rack is located inside the positioning frame. An electric push rod B is fixedly connected to the top inner side of the positioning frame. Its telescopic rod is fixedly connected to the rack. The top of the driving block is fixedly connected to a gear and meshes with the rack. When the electric push rod B is working, it pushes the rack to slide on the left side of the control box. Through the meshing transmission of the gear and the rack, the driving block is driven to rotate, thereby adjusting the angle of the wireless charging module and realizing automatic coil alignment.

[0007] In one embodiment, a dust cover is also included. The support block is provided with a dust cover, one end of which is fixed to the control box and the other end of which is fixed to the fixing plate, which can effectively prevent dust and debris from entering the robotic arm.

[0008] In one embodiment, a foot is also included, which is fixedly connected to the bottom surface of the control box to increase the contact area and friction with the placement surface.

[0009] In one embodiment, a rubber sleeve is also included, with a rubber sleeve for increasing friction provided between the driving block and the two fixed plates.

[0010] In one embodiment, a protective cover is also included, which is fitted onto the wireless charging module to prevent interference with adjacent devices.

[0011] The beneficial effects of this utility model are as follows: 1. By controlling the extension and retraction of the electric push rod A through the box, the fixed plate slides on the support block, thereby driving the moving block to adjust its position. The moving block can rotate, and the wireless charging module fixed on it moves and changes its angle accordingly, so as to achieve precise alignment with the charging device. The support block provides a sliding track for the fixed plate. All components work closely together, so that the robotic arm can flexibly adapt to different planes and positions, ensuring that wireless charging is efficient and accurate.

[0012] 2. The rack slides vertically on the left side of the control box via telescopic movement. The gear at the top of the drive block meshes with the rack. When the rack moves, the gear rotates under its drive, thereby adjusting the angle of the drive block and the wireless charging module fixed on it. The positioning frame provides guidance and limits for the rack's movement, ensuring precise transmission and enabling the robotic arm to adapt to charging needs at different tilt angles, thus improving the device's adaptability.

Detailed Implementation

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] Example: A high-power wireless charging coil automatically aligns with a robotic arm, such as... Figure 1-3As shown, the system includes a control box 1, a wireless charging module 101, a support block 2, a fixing plate 3, an electric push rod A4, and a drive block 5. The support block 2 and the electric push rod A4 are fixedly connected to the left side of the control box 1. The fixing plate 3 is slidably connected to the upper and lower sides of the support block 2. The telescopic rod of the electric push rod A4 is fixedly connected to the fixing plate 3. The drive block 5 is rotatably connected between the two fixing plates 3. The drive block 5 can rotate between the fixing plates 3 to change its angle. The front-facing side of the drive block 5 is fixedly connected to the wireless charging module 101. The system also includes a positioning frame 6, a rack 7, an electric push rod B8, and a gear 9. The positioning frame 6 is fixedly connected to the left side of the control box 1, and the rack 7 is slidably connected thereto. The right end of the rack 7 is located inside the positioning frame 6. The electric push rod B8 is fixedly connected to the top inner surface of the positioning frame 6, and its telescopic rod is fixedly connected to the rack 7. The gear 9 is fixedly connected to the top of the drive block 5 and meshes with the rack 7. It also includes a dust cover 10, which is mounted on the support block 2. One end of the dust cover 10 is fixed to the control box 1, and the other end is fixed to the fixing plate 3. It also includes feet 11, which are fixedly connected to the bottom surface of the control box 1. It also includes rubber sleeves 12, which are respectively provided between the driving block 5 and the two fixing plates 3. Finally, it includes a protective cover 13, which is fitted onto the wireless charging module 101.

[0019] When the robotic arm detects a horizontal shift in the device requiring charging, the electric push rod A4 activates. The extension and retraction of its telescopic rod causes the fixed plate 3 to move left and right on both sides of the support block 2. The fixed plate 3 then adjusts the position of the rotating block 5, ensuring that the wireless charging module 101, fixed to the front end of the rotating block 5, is precisely aligned horizontally with the device to be charged, achieving automatic alignment and effectively improving the device's response accuracy and usability to changes in device position. If the device requiring charging is detected to be tilted or positioned on a non-standard plane such as the side, the electric push rod B8 activates first. Its telescopic rod pushes the rack 7 downwards until the rack 7 fully engages with the gear 9 at the top of the rotating block 5. At this time, the electric push rod A4 activates again, pulling the fixed plate 3 back, which in turn moves the rotating block 5. Since the right end of the rack 7 is connected to the control box 1, it can only move in the vertical direction. During the movement of the drive block 5 driven by the fixed plate 3, the gear 9 meshes with the rack 7, causing the gear 9 to drive the drive block 5 to rotate, thereby adjusting the angle of the wireless charging module 101. In this way, the robotic arm can adapt to charging needs at different angles and positions, significantly improving the adaptability and application range of the device. During the operation of the robotic arm, the dust cover 10 on the support block 2 encloses key components such as the control box 1, the electric push rod A4, and the fixed plate 3, effectively preventing external dust, particles, and other debris from entering. This avoids dust accumulation affecting the extension and retraction performance of the electric push rod and the normal operation of other components, thereby extending the overall service life of the equipment. The feet 11 on the bottom of the control box 1 increase the contact area and friction between the robotic arm and the placement surface. Whether during equipment handling or working in different planar environments, this ensures the robotic arm remains stable, preventing alignment deviations of the wireless charging module 101 caused by shaking, and enhancing the operational stability of the equipment. The rubber sleeve 12 between the driving block 5 and the fixed plate 3 increases the friction at their contact points, making the driving block 5 more stable when rotating to adjust the angle, avoiding slippage or loss of angle control, and further ensuring the accuracy and stability of the angle adjustment of the wireless charging module 101. The protective cover 13 outside the wireless charging module 101 shields the electromagnetic interference generated during wireless charging, preventing it from affecting the normal operation of surrounding equipment, ensuring stable operation of the robotic arm in complex equipment environments, and improving the overall reliability of the equipment.
