[0018] Operation principle: Regarding the drive assembly 1, it includes a tool tray 101, a locking rod 102, a guide positioning plate 103, a diamond pin 104, a ramp block 105, a drive shaft 106, a transition base 107, and a bearing seat 108, which are prior art and will not be described in detail here;
[0019] Regarding the wire breaking transmission assembly 2, it includes a small arc gear 201, a large arc gear 202, a keyless bushing 203, a mounting base 204, a nut bracket 205, a nut 206, a ball screw 207, a T-type push rod 208, a support rod 209, a support pin 210, a support connecting rod 211, a shearing knife 212, a shearing knife shaft 213, and a lock nut 214: the small arc gear 201 is connected to the drive shaft 106, and the small arc gear 201 is driven by the drive shaft 106.

The two ends of the T-shaped push rod 208 are rotatably connected to the support link 211. After the nut bracket 205 drives the T-shaped push rod 208 to move upward, the support link 211 drives the shear knife 212 to move, cutting the wire;
[0020] Regarding the wire protection assembly 3, it includes a wire protection base plate 301, a side mounting seat 302, a lower mounting seat 303, a lower sliding column 304, a side lower sliding column 305, a side upper mounting seat 306, a side sliding column 307, a tension spring 308, a side upper sliding column 309, a sliding swing frame 310, a spring pillar 311, a wire clamping seat 312, a moment spring 313, a wire clamping block 314, and a shoulder screw 315: the wire clamping seat 312 is installed on the shearing knife 212 and moves with the shearing knife 212. When the shearing knife 212 cuts the wire, the wire clamping block 314 can just clamp the wire to prevent The reason for setting the lower sliding post 304, the lower side sliding post 305 and the upper side sliding post 309 is to facilitate the sliding of the wire (in actual operation, the robot cannot be positioned at the precise position at one time, so it is necessary to move the robot to adjust the shearing position. Without these sliding posts, the wire will directly contact the shear knife, and the friction will increase greatly when moving, and other parts of the wire will also be damaged). Both sides of the wire protection base plate 301 are provided with mounting cylinders, and a spring is provided in the mounting cylinder, and a spring support 311 is provided in the spring. By squeezing the spring and The spring is deformed and restored, and the spring support 311 can move along the axis of the mounting tube so as to contact or not contact the sliding swing frame 310, thereby realizing the limit of the sliding swing frame 310. The limit of the sliding swing frame 310 is to prevent the intervention of the second wire during the shearing process, thereby accidentally cutting the second wire as well (in actual operation, it is possible to encounter a situation where the vertical distance between the two wires is very short, but only the lower one needs to be cut. At this time, if the sliding swing frame 310 is not opened and closed, the two wires may enter the shearing range of the shear knife together, and then To prevent the two wires from being cut together, when the shear blade rotates, the sliding swing frame 310 tends to be closed to prevent the upper wire from entering: in the original state, there is a through hole on the shear blade, and the spring support 311 is inside the through hole. The sliding swing frame 310 is not limited, and the wire enters. After the wire enters, the shear blade starts to rotate, and the through hole squeezes the spring support 311. The through hole is curved, and the spring support 311 is squeezed out, thereby limiting the sliding swing frame 310 and closing the upper part, so that the second wire cannot enter.).
[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
