[0024] The electric push rod is started, and the mounting frame 201 provides support for the electric push rod. The telescopic end of the electric push rod extends outward, and the electric push rod drives the propulsion plate to move. The propulsion plate moves along the track. When the propulsion plate moves, it drives the flip mechanism 2, the intermittent mechanism 3 and the clamping assembly 4 to move.

[0025] The flipping mechanism 2 also includes a rotating plate 203, a curved track 204 and a flipping rod 205. The rotating plate 203 is installed on the propulsion assembly 202.

When the rotating plate 203 moves to the bend of the curved track 204, the roller on one side of the rotating plate 203 begins to deviate along the trajectory of the curved track 204 and drives the rotating plate 203 to start rotating. When the roller moves to the horizontal position of the curved track 204, the roller drives the rotating plate 203 to rotate ninety degrees, and the rotating plate 203 drives the flip rod 205 to rotate ninety degrees. The flip rod 205 drives the intermittent mechanism 3 and the clamping assembly 4 to rotate ninety degrees.

A balancing plate 902 is fixedly connected to the upper right part of one side of the second slide 6. The lifting plate 903 is slidably connected in the balancing plate 902. The balancing plate 902 limits the moving trajectory of the lifting plate 903. The lifting plate 903 is fixedly connected to the support plate 904, and the extrusion plate 905 is hinged on the support plate 904.

[0038] The material return mechanism 9 also includes an extrusion rod 906, a guide connecting plate 907, a material return plate 908 and a material receiving hopper 909. The extrusion rod 906 is hinged on the extrusion plate 905, and the guide connecting plate 907 is fixedly connected to the lifting plate 903. A notch is provided on the guide connecting plate 907. The extrusion rod 906 is hinged to the material return plate 908 through the guide connecting plate 907. The guide connecting plate 907 is used to limit the moving trajectory of the extrusion rod 906 and the material return plate 908. A spring is provided in the notch of the guide connecting plate 907, and a material receiving hopper 909 is installed on the base 1.

[0039] After the line-following plate 808 pulls out the cable, the cylinder is started, and the telescopic end of the cylinder drives the lifting plate 903 to rise in the balance plate 902 through the connecting rod, and the lifting plate 903 drives the extrusion plate 905 to move upward through the support plate 904. When the extrusion plate 905 moves to a position parallel to the positioning seat 503, the telescopic rod of the cylinder stops extending, and at the same time, the driving mechanism 5 drives the positioning seat 503 to move toward the extrusion plate 905. When the connection of the positioning seat 503 is against the extrusion plate 905, the extrusion plate 905 is forced to move to the side away from the positioning seat 503, and the extrusion plate 905 is hinged with the extrusion plate 905 and the support plate 904. The joint rotates as the center of a circle. When the driving mechanism 5 drives the positioning seat 503 to move to the side away from the extrusion plate 905, the extrusion plate 905 is not squeezed and reset by the positioning seat 503. When the extrusion plate 905 is squeezed and rotated by the positioning seat 503, the extrusion plate 905 drives the extrusion rod 906 to move. One end of the extrusion rod 906 drives the stripping plate 908 to move through the guide connecting plate 907. The stripping plate 908 is forced to move along the trajectory of the guide connecting plate 907, and then one end of the stripping plate 908 contacts the surface of the injection-molded plug. The plug is forced to drive the plug piece to withdraw from the positioning seat 503 to the outside and fall into the receiving hopper 909.
