The present invention is by no means limited to any specific configuration and algorithm proposed below, but covers any modification, replacement and improvement of elements, parts and algorithms without departing from the spirit of the present invention. In the following description, known structures and technologies are not shown to avoid unnecessary ambiguity to the present invention.

[0023] Example embodiments will now be described with reference, and the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concept of the example embodiments to those skilled in the art.

[0024] In addition, the described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solution of the present invention may be practiced without one or more of the specific details, or other methods, components, materials, etc. may be adopted. In other cases, known structures, materials or operations are not shown or described in detail to avoid blurring the main technical creativity of the present invention.

[0025] like Figure 1-7 As shown, the present embodiment provides an automatic wiring device for railway terminal blocks, comprising a connecting mechanism, a positioning clamping mechanism, and a wire retracting mechanism fixedly mounted on a frame 1, wherein the connecting mechanism is located at the rear end of the frame and is used to be fixedly connected to the mechanical arm; the positioning clamping mechanism comprises two parallel frames formed on the frame, a positioning baffle plate laterally connected between the two frames, a clamp 34 connected between the two frames through an axis 31 and located above the positioning baffle plate 33, and having a drooping clamping opening at the front end, a spring 32 is arranged between the clamp and the positioning baffle plate 33, and the lower end of the spring is provided with a spring. The end is embedded in the spring groove 35 on the upper surface of the positioning baffle 33, and the upper end support point of the spring 32 is not at the position of the shaft 31, so that the clamp 34 can be reset under the action of the spring 32 after rotating around the axis, and the lower edge of the clamp is docked with the lip on the frame; the wire withdrawal mechanism includes a wire withdrawal door 27, and the wire withdrawal door 27 is driven to move relative to the frame by a push rod 28 and a cylinder 30 arranged on the frame 1. The wire withdrawal door 27 is connected with the frame 1 and forms a threading hole 29 on the docking surface after connection. The threading hole 29 is located between the two frame frames behind the positioning baffle 33.

[0026] First, the device and the terminal board are accurately positioned through the positioning wire clamping mechanism, and the wiring hole is inserted into the positioning hole of the device. Then the wire passes through the wire threading hole and out of the hole on the terminal for a certain length. Then the end of the robotic arm drives the device to move a certain distance in the opposite direction perpendicular to the terminal. The wire also moves a distance with the device, and the wire is clamped by the clamp, so that the end of the robotic arm drives the device to rotate one circle parallel to the terminal board. At this time, the wire has been ring-shaped around the wiring hole of the railway terminal board. Then the wire can be fixed to the wiring hole through welding with a spot welding gun to complete the wiring. Finally, the cylinder controls the extension and retraction of the push rod to open and close the wire withdrawal door to complete the wire withdrawal.

[0027] The butt joint surfaces of the frame 1 and the wire withdrawal door 27 are grooved respectively, so that a passage with a wire threading hole 29 is formed after the two are butted. The wire threading hole 29 is located inside the frame 1, and the wire enters the positioning wire clamping mechanism through the wire threading hole 29 for positioning and wire clamping. The wire passes through the wire threading hole 29 and exposes a certain length through the plug-in hole. The entire mechanism moves outward through the mechanical arm to make the plug-in come out of the positioning hole, and the wire also moves out a distance with the device. The clamp 34 and the frame 1 are clamped by the force of the spring 32, and the end of the mechanical arm drives the entire device to rotate 360 ​​degrees counterclockwise. At this time, the wire has been ring-shaped around the wiring hole of the railway terminal board, and then the wire can be fixed to the wiring hole by welding with a spot welding gun, and the wiring operation is completed.

[0028] The cylinder 30 is fixed on the frame by a fixing block, and a cylinder hole 2 for fixing the cylinder 30 is provided on the frame corresponding to the position of each cylinder 30. The air intake control push rod 28 is telescopically opened and closed by the air intake hole 37.

[0029] The connection mechanism includes a fixing plate 38, which is in a "convex" shape, with both ends connected to the frame 1 by bolts, and a raised portion in the middle fixedly connected to the mechanical arm by bolts.

[0030] The automatic wiring device provided by the present invention can accurately position the positioning clamping mechanism, and the cylinder and the push rod can control the wire withdrawal door to open to complete the wire withdrawal task. The entire mechanism is flexible and compact, and can complete the wire clamping and the threading and wiring composite operations with the assistance of the mechanical arm.

[0031] Those skilled in the art should understand that the above embodiments are exemplary rather than restrictive. Different technical features appearing in different embodiments can be combined to achieve beneficial effects. Those skilled in the art should be able to understand and implement other variations of the disclosed embodiments based on the study of the specification and claims. In the claims, the term "comprising" does not exclude other devices or steps; the indefinite article "a" does not exclude a plurality; the terms "first" and "second" are used to indicate names rather than to indicate any particular order.
