[0028] Reference Figures 1 to 5 A lifting device for a high-voltage wire harness assembly line includes a frame 1, a lifting part 2, and a shuttle trolley 3. The frame 1 is an aluminum alloy frame. The lifting part 2 is arranged on one side of the frame 1. The shuttle trolley 3 is connected to the lifting part 2. The lifting part 2 can drive the shuttle trolley 3 to move up and down, and the shuttle trolley 3 can move forward and backward to transport the tooling plate for assembling the wire harness.

[0029] The frame 1 is provided with a slide rail portion 11 and a protective door 12. The slide rail portion 11 includes a slide rail fixing frame 111, a linear slide rail 112, and a linear slider 113. The slide rail fixing frames 111 are arranged in pairs on the frame 1, the linear slide rail 112 is arranged on the slide rail fixing frame 111, and the linear slider 113 moves along the linear slide rail 112 and is fixedly connected to the bracket 31 of the shuttle vehicle 3.

[0030] The lifting part 2 includes a lifting cylinder 21, a middle connecting rod 22, a sprocket shaft 23, a driven sprocket 24, a lifting chain 25, and a chain tensioning adjusting bolt 26. The lifting cylinder 21 is arranged on the frame 1 through a fixing seat, the middle connecting rod 22 is connected to the piston rod of the lifting cylinder 21, the sprocket shaft 23 is connected to the middle connecting rod 22, the driven sprocket 24 is arranged on both sides of the sprocket shaft 23, the lifting chain 25 is connected to the driven sprocket 24, and the two ends of the lifting chain 25 are respectively connected to the bottom of the frame 1 and the shuttle 3. In order to ensure that the shuttle 3 remains relatively stable when performing vertical movement, chain tensioning adjusting bolts 26 are arranged at both ends of the lifting chain 25; The lowering cylinder 21 drives the lifting chain 25 to move, and then the lifting chain 25 drives the shuttle vehicle 3 to move vertically up and down along the slide rail part 11 set on the frame 1, so that the shuttle vehicle 3 can lift the tooling plate in situ at the head and tail ends of the high-voltage wire harness assembly line. At the same time, a magnetic sensor 211 is provided on the lifting cylinder 21 to detect the travel position of the shuttle vehicle 3. When the shuttle vehicle 3 descends, it can only descend to a specified travel position. After being sensed by the magnetic sensor 211 on the lifting cylinder 21, the platform stops running. When the shuttle vehicle 3 rises, it can only rise to a specified travel position. After being sensed by the magnetic sensor 211 on the lifting cylinder 21, the platform stops running.

[0031] The shuttle vehicle 3 includes a bracket 31, a conveying belt 32, a conveying motor 33, and a side guide plate 34. One side of the bracket 31 is fixedly connected to the slide rail portion 11. The bracket 31 is provided with a conveying belt 32 and a conveying motor 33. The side guide plates 34 are arranged on both sides of the bracket 31. The conveying motor 33 drives the conveying belt 32 to rotate, thereby causing the tooling plate on the conveying belt 32 to move horizontally to the production line.

[0032] The following will refer to Figures 1 to 5 , the working principle of the utility model is explained.

[0033] First, the lifting devices of the utility model are respectively arranged at the head and tail ends of the high-voltage wire harness assembly line. The assembly line has an upper and lower double-layer assembly line. Before operation, the upper assembly line is covered with tooling plates. Before the tooling plates move horizontally from the lifting device at the left end to the lifting device at the right end, after the shuttle trolley 3 of the lifting device at the right end receives the tooling plates, the lifting part 2 descends and drives the shuttle trolley 3 to move downward. When the shuttle trolley 3 descends to be connected to the lower assembly line, the lifting part 2 stops running, and the shuttle trolley 3 starts running, and transmits the tooling plates to the lifting device at the left end through the lower assembly line. When the tooling plates arrive at the lifting device at the left end, the shuttle trolley 3 receives the tooling plates, and then the lifting part 2 rises and drives the shuttle trolley 3 to move upward. When the shuttle trolley 3 is connected to the upper assembly line, the lifting part 2 stops running, and the shuttle trolley 3 starts running to transmit the tooling plates to the upper assembly line. In this way, the tooling plates at the head and tail ends of the assembly line can be lifted and lowered in situ, thereby improving assembly efficiency and increasing production capacity.

[0034] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
