Based on the existing structure of the line loss detection mechanism, the embodiment of the present invention is different from the existing technology in that the turnover mechanism 40 is disposed, and specifically, the turnover mechanism 40 can rotate 360 degrees along the axis direction of the electric wire, so as to realize multi-point detection of the detection mechanism 20, and further improve accuracy of line loss examination.
The existing production line type workbench generally directly utilizes an intermittent conveyor belt to realize intermittent transmission of electric wires, and the transmission mode of the conveyor belt can cause the bottoms of the electric wires to be in direct contact with the conveyor belt, which is not beneficial to the operation of the detection mechanism 20 and the turnover mechanism 40, so in the embodiment of the invention, the transmission mechanism 30 comprises a bottom support sliding wheel 31 and an extrusion transmission wheel 32; first connecting rods 33 are rotatably mounted on two sides of the bottom support sliding wheel 31, the bottom support sliding wheel 31 rotates around the center of a circle, and the first connecting rods 33 are fixed on the upper surface of the detection table 10; the two sides of the extrusion transmission wheel 32 are rotatably connected with second connecting rods 34, the circle center of the extrusion transmission wheel 32 is spaced from the rotating center of the extrusion transmission wheel 32, the second connecting rods 34 are hoisted right above the bottom support sliding wheel 31, and the extrusion transmission wheel 32 is connected with a power piece for driving the extrusion transmission wheel to rotate; the gap between the shoe sliding wheel 31 and the extrusion transmission wheel 32 forms a channel for the electric wire to pass through, and the extrusion transmission wheel 32 is attached to the outer surface of the electric wire.
Based on the conventional mechanism of the transmission mechanism 30, the principle of the electric wire transmission operation performed by the embodiment of the present invention is as follows: the eccentrically-mounted extrusion transmission wheel 32 is similar to a cam structure, when the distance between the extrusion transmission wheel 32 and the bottom-support sliding wheel 31 is reduced, the electric wire moves towards a fixed direction under the rotating action of the extrusion transmission wheel 32, when the distance between the extrusion transmission wheel 32 and the bottom-support sliding wheel 31 is changed, the extrusion action of the extrusion transmission wheel 32 on the electric wire is reduced, and when the distance is lower than a certain value, the electric wire cannot be continuously transmitted.
In the above process, the extrusion transfer wheel 32 is kept rotating at all times, and the specific down time can be suitably adjusted by changing the diameter of the extrusion transfer wheel 32 or changing the rotating speed of the extrusion transfer wheel 32 so that the turnover mechanism 40 does not move during the wire transfer, and the turnover mechanism 40 performs the turnover operation on the wire at the time of the wire down time.

The combination structure of the intermittent clamping seat 41 and the fixed-angle rotating piece 42 forms an intermittent rotating mechanism, and the fixed-angle rotation of the intermittent clamping seat 41 is realized through the fixed-angle rotating piece 42.
The intermittent clamping operation of the intermittent clamping base 41 on the electric wire needs to be synchronous with the rotation of the fixed-angle rotating piece 42, so that the fixed-angle rotating piece 42 synchronously drives the intermittent clamping base 41 to drive the electric wire to rotate at a fixed angle while the intermittent clamping base 41 clamps the electric wire.
In the embodiment of the present invention, in order to simplify the design, a circular hole 411 for the electric wire to pass through is formed in the center of the intermittent clamping seat 41, a plurality of circular arc pieces 412 are disposed in the circular hole 411, and each circular arc piece 412 passes through the intermittent clamping seat 41 through a linkage rod 413 and extends into the first opening 43; a force-bearing block 414 connected with the end of the linkage rod 413 is arranged in the first opening 43, a first spring 415 is connected between the force-bearing block 414 and the bottom of the first opening 43, and the active block 423 entering the first opening 43 applies pressure to the force-bearing block 414 so that the circular arc piece 412 presses the electric wire in the circular hole 411.
