Description

Technical Field

[0001] The utility model relates to the technical field of a wire routing mechanism of a manipulator, in particular to a wire routing mechanism of a multi-axis manipulator. Background Art

[0002] At present, multi-axis manipulators are products with a relatively high utilization rate in industrial automation. They are usually used for handling workpieces. When combined with pneumatic grippers, electric grippers, vacuum suction cups, etc., horizontal movement, height adjustment, and angle adjustment of workpieces can be achieved.

[0003] If a multi-axis manipulator is to be used for high-precision work, a set of cameras and light sources need to be added to the manipulator to achieve precise positioning of the workpiece, and then cooperate with pneumatic grippers, electric grippers, vacuum suction cups, etc. to complete high-precision assembly work.

[0004] However, pneumatic grippers, vacuum suction cups, cameras, light sources, etc. used in conjunction with it need to be fixed on the Z-axis of the multi-axis manipulator. The air pipes for driving the grippers and suction cups, sensors, and cables for the camera light sources will thus be fixed on the multi-axis manipulator. When the manipulator works, all air pipes and cables will be pulled and bent due to the up and down, horizontal movement, and rotation of the Z-axis of the manipulator. After long-term repeated pulling and bending of the cables, the service life will be greatly reduced, and then the fracture phenomenon will occur. Summary of the Invention

[0022] To more clearly and completely illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the drawings.

[0023] Please refer to Figures 1-3, the present utility model proposes a wire routing mechanism for a multi-axis manipulator, which includes a mounting frame 1. The outer wall of the mounting frame 1 is fixedly connected with a limiting frame 2 by bolts. The top of the inner wall of the limiting frame 2 is fixedly connected with a protective cover 3 by bolts. A height adjustment device 4 is arranged on the inner wall of the protective cover 3. On the side of the outer wall of the mounting frame 1 away from the limiting frame 2, a drag chain 6 is fixedly connected by bolts. A cable is arranged in the inner cavity of the drag chain 6, and one end of the drag chain 6 away from the mounting frame 1 is fixedly connected to the bottom of a protection box 5. The shape of the mounting frame 1 is L-shaped, and a threaded hole is opened at the top of the mounting frame 1. By using the cooperation of the threaded hole at the top of the mounting frame 1 and bolts, the device can be installed at the corresponding position. The cable is passed through the inner cavity of the drag chain 6, and the cable is connected to the corresponding components. The drag chain 6 is used to protect the internal cable, preventing the messy situation caused by a large number of cables during use, and at the same time preventing the cable from being damaged. Moreover, the drag chain 6 reduces the space occupied by the cable layout, facilitating the maintenance personnel to check and repair the circuit. The device is powered by the cable arranged inside the drag chain 6.

[0024] The height adjustment device 4 includes a lifting cylinder 401 and a fixing frame 405. When the lifting cylinder 401 works, it drives the fixing frame 405 to lift for height adjustment. The outer wall of the lifting cylinder 401 is fixedly connected with an air valve 402 by bolts, and one end of the air valve 402 away from the lifting cylinder 401 is connected to an air pump. The power rod end of the lifting cylinder 401 is fixedly connected with a transmission rod 403 by bolts. The bottom of the transmission rod 403 is fixedly connected to the top of the fixing frame 405. Control the lifting cylinder 401 to work, push the transmission rod 403 to lift, and at the same time drive the lifting plate 404 to lift. Then, by using the bellows 7 arranged at the top and bottom of the lifting plate 404, the bellows 7 can contract and move to protect the transmission rod 403. When the lifting plate 404 lifts, it drives the fixing frame 405 to lift, and the height of the clamping device installed on the top of the fixing frame 405 can be adjusted.

[0025] The outer wall of the transmission rod 403 is fixedly sleeved with a lifting plate 404. The inner cavity of the limiting frame 2 is a hollow structure, and the outer wall of the lifting plate 404 is slidably connected to the inner wall of the limiting frame 2. Bellows 7 are arranged at the top and bottom of the lifting plate 404, and the outer wall of the bellows 7 is slidably connected to the inner wall of the limiting frame 2. The outer wall of the protective cover 3 is fixedly connected with a protection box 5 by bolts, and the inside of the protection box 5 is a hollow structure. The air valve 402 is located in the inner cavity of the protection box 5. The limiting frame 2 is used to limit the lifting plate 404 to keep the lifting plate 404 moving straight up and down.

[0026] Working principle: During use, the cable is passed through the inner cavity of the cable carrier 6 and connected to the corresponding components. The cable carrier 6 is used to protect the internal cable, preventing the cable from getting messy due to a large number of cables during use. At the same time, it can prevent the cable from being damaged, and the cable carrier 6 reduces the space occupied by the cable arrangement, facilitating the maintenance personnel to check and repair the circuit. The internal cable of the cable carrier 6 is connected to the corresponding controller to control the operation of the lifting cylinder 401, pushing the transmission rod 403 to lift and drive the lifting plate 404 to lift. Then, by using the bellows 7 provided at the top and bottom of the lifting plate 404, the bellows 7 can contract and move to protect the transmission rod 403. When the lifting plate 404 lifts and lowers, it drives the fixed bracket 405 to lift and lower, enabling the height adjustment of the clamping device installed on the top of the fixed bracket 405, improving the practicality of the device.

[0027] Of course, the present utility model can also have many other implementation manners.
