[0048] The stroke of the first cylinder 312 is controlled and adjusted by the limit screw 310 on the seventh connecting plate 307, and the relative position of the clamping mechanism 4 for gripping the product can be adjusted; when the first cylinder 312 on the sixth connecting plate 306 is closed, the first cylinder 312 drives the pull ring 311 and the fifth connecting plate 305 to move, the fifth connecting plate 305 drives the fourth connecting plate 304 to move, the slider 314 is driven by the fourth connecting plate 304 to slide on the slide rail 313, the fourth connecting plate 304 drives the third connecting plate 303 to move leftward, and the buffers 309 on the eighth connecting plate 308 and the seventh connecting plate 307 buffer the fourth connecting plate 304 and the fifth connecting plate 305 respectively, playing a role in buffering the movement when rotating in place and ensuring the accuracy of the position, and being convenient for adjustment and control; when the third connecting plate 303 moves leftward, the second bearing group 316 moves downward in the waist slot 324 of the third connecting plate 303, the second bearing group 316 drives the first rotating shaft 318 to move, and the first rotating shaft 318 will drive the first bearing group 315 and the third bearing group 317 on the first connecting plate 301 and the second connecting plate 302 to slide in the first arc-shaped slot 325 and the second arc-shaped slot 326 of the vertical plate 2 respectively. The first bearing group 315 and the third bearing group 317 rotate the first connecting plate 301 and the second connecting plate 302 through the first rotating shaft 318 and the second rotating shaft 319, so that the clamping mechanism 4 on the first connecting plate 301 drives the product body 5, wire A 6 and wire B 7 to rotate 90 degrees clockwise around the axis of wire B 7, thereby changing the relative positions of wire A 6 and wire B 7 on the product body 5, ensuring that the position of wire B 7 remains unchanged, ensuring the distance between the two wires, and avoiding the intersection and misalignment of the two wires. At the same time, the limit screw 310 on the eighth connecting plate 308 controls and adjusts the stroke of the first cylinder 312, and the rotation angle of wire A 6 on the product body 5 relative to the rotation center line B 7 can be adjusted; after the product body 5 that has rotated in place is grabbed by the subsequent workstation, the clamping mechanism 4 releases wire A 6 and wire B 7 on the product body 5. After the released product body 5 is taken away by the subsequent operation, at the same time, the next product arrives, the first cylinder 312 opens, drives the second bearing group 316 to move upward in the waist slot 324 of the third connecting plate 303, drives the first bearing group 315 and the third bearing group 317 to slide in the arc-shaped slot of the vertical plate, and drives the clamping mechanism 4 to return to its position for the next operation; the first cam bearings 320, second cam bearings 321, third cam bearings 322 and fourth cam bearings 323 provided at the ends of the first connecting plate 301 and the second connecting plate 302 are fitted and installed on both sides of the vertical plate 2, which can prevent the clamping mechanism 4 from driving the product to swing when the first connecting plate 301 and the second connecting plate 302 rotate, ensuring the smooth and effective rotation.

[0049] The clamping mechanism 4 is arranged on one side of the rotating mechanism 3, and the workpiece is clamped and fixed by the clamping mechanism 4.

[0050] The clamping mechanism 4 includes a second cylinder 401 and a jaw 402. The second cylinder 401 is fixedly connected to one side of the first connecting plate 301, and the jaw 402 is arranged on the front mounting column of the second cylinder 401.

[0051] The jaw 402 is provided with a V-shaped groove, and the clamping mechanism 4 can rotate at an angle not limited to 90 degrees through the rotating mechanism 3.

[0052] When the second cylinder 401 closes, it drives the jaw 402 to close and grab the wire A6 and wire B7 on the product body 5. Since the clamping surface of the jaw 402 is designed in the shape of a V-groove, the jaw 402 can effectively ensure the relative positions of the wire A6 and wire B7 on the product body being grabbed; after the rotating mechanism 3 rotates the product body 5, wire A6 and wire B7 90 degrees clockwise around the axis of wire B7, the second cylinder 401 opens, driving the jaw 402 to open and release the wire A6 and wire B7 on the product body 5; after the release, the product body 5 is taken away by the subsequent operation.

[0053] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
