The second clamping block is forced to slide along the second fixed rod and compress the No. 2 spring, thereby fixing the cable.

[0011] According to the above technical solution, the docking device also includes a positioning rod, a wrapping frame and a welding frame. The positioning rod is fixedly installed on the surface of the fixed ring, and the rotating ring is restricted from rotating by the positioning rod. The welding frame is fixedly installed on the top of the base, and the wrapping frame is rotatably installed on the inner wall of the welding frame.

The hollow block is fixedly installed on the left side of the welding frame, the insert block is slidably installed on the inner wall of the hollow block, the U-shaped block is slidably installed on the inner wall of the hollow block, and the No. 3 spring is arranged between the insert block and the U-shaped block. By moving the parcel rack, the outer wall of the parcel rack is in contact with the insert block, so that the insert block moves to the left. The movement of the insert block will compress the No. 3 spring.

[0013] According to the above technical solution, the welding device also includes a T-shaped block, a pin and a positioning sleeve. One side of the T-shaped block is slidably installed on the inner wall of the hollow block, and the other side of the T-shaped block is fixedly installed on the inner wall of the U-shaped block.

After the welding cooling is completed, the pin is pressed to make the pin contact with the inclined surface of the T-shaped block, so that the T-shaped block moves to the left. The movement of the T-shaped block drives the movement of the U-shaped block. The movement of the U-shaped block will stretch the No. 3 spring. When the No. 3 spring is stretched to a certain extent, it will pull the plug block to move, so that the plug block is out of the docking groove. At this time, the wrapping rack can be rotated to take out the welded cable.

[0014] A repair process of a cable minimally invasive welding repair device, comprising the following steps: Step 1: Put the cable into the inner wall of the fixing frame, rotate the rotating rod to make the clamping rod clamp the cable, insert the clamping block into the clamping slot to prevent reversal, rotate the motor to make the slider drive the moving rod of the fixing frame to move the clamping device, so as to facilitate the appropriate adjustment of different cable lengths; Step 2: Place another cable on the clamping block 1, rotate the rotating circle to fit the fixed circle, so that the cable is clamped by the clamping block 1 and the clamping block 2, limit the movement of the rotating circle by the positioning rod, rotate the fixed circle by rotating the motor 2, and rotate the cable by the fixed circle, which can ensure that the cable is heated evenly during welding. By inserting the two cables into the welding frame, the cable is prepared for welding; Step 3: Put the welding frame in contact with the wrapping frame, make the two fit together through the plug block and the docking groove, add the welding material from the top of the welding frame, and use the robot arm to drive the welding gun to insert into the welding frame. Use the positioning sleeve to position the welding gun. After the welding is completed and cooled, the wrapping frame can be rotated by pressing the pin, and the welded cable can be taken out.

[0015] The working principle and beneficial effects of the present invention are: 1. In the present invention, through the setting of the clamping device, the processed cable is placed on the inner wall of the fixed frame one, and the cable is clamped by rotating the rotating rod in cooperation with the spiral groove two, the rotating block, the sliding sleeve, the fixed sleeve, the limit block, the clamping rod and the pulley. When the rotating rod stops rotating, the rotating rod cannot rotate by inserting the card block into the card groove, and the moving distance of the card block is limited by the limit rod. By realizing anti-reversal of the rotating rod, it can be prevented that the rotating rod is accidentally touched by external force and rotates, so that the cable clamping effect is lost, and repeated adjustments caused by reversal are avoided, thereby improving work efficiency and operation fluency. The clamping device is moved by rotating the rotating motor one in cooperation with the screw rod, the spiral groove one, the slider and the fixed frame one, so as to adapt to the repair of cables of different lengths.

[0016] 2. In the present invention, through the setting of the docking device, by placing another cable on the clamping block one, the rotating circle is rotated to fit with the fixed circle. At this time, the clamping block two is in contact with the cable, and the cable is fixed by the clamping block one, the fixed rod one, the No. 1 spring, the clamping block two, the fixed rod two and the No. 2 spring. The rotating circle is restricted from rotating by the positioning rod. The rotating motor two rotates and cooperates with the No. 1 belt, the rotating rail, the fixed circle and the rotating circle to drive the cable to rotate. The rotation can ensure that the cable welding area is heated evenly and reduce local overheating or uneven cooling. By inserting the cables on both sides into the welding frame and rotating the wrapping frame to fit with the welding frame, the cable can be prepared for welding.

[0017] 3. In the present invention, by setting up the welding device, the wrapping rack is moved so that the outer wall of the wrapping rack contacts the plug block and cooperates with the No. 3 spring and the docking groove to realize the docking of the wrapping rack and the welding rack, so as to prevent the welding material from leaking therefrom due to the poor fit of the docking, thereby damaging the cable or the device. At this time, the welding material is added from the top of the welding rack, and the welding gun is driven by the mechanical arm to insert into the welding rack, and the position of the welding gun is positioned by the positioning sleeve, and the cables on both sides are welded by the welding gun. After the welding cooling is completed, the restriction of the wrapping rack can be released by pressing the pin to cooperate with the T-shaped block, U-shaped block, No. 3 spring, plug block and docking groove, and then the welded cable is taken out to complete the welding.

The cable is fixed by rotating the rotating circle 26 to fit the fixed circle 22, and the clamping block 22 is reset by the arranged No. 2 spring 28.

[0029] The docking device also includes a positioning rod 210, a wrapping frame 211 and a welding frame 212. The positioning rod 210 is fixedly installed on the surface of the fixing ring 22, the welding frame 212 is fixedly installed on the top of the base 1, and the wrapping frame 211 is rotatably installed on the inner wall of the welding frame 212. The inner wall of the wrapping frame 211 is provided with a docking groove. By inserting the cables on both sides into the welding frame 212 and rotating the wrapping frame 211 to fit with the welding frame 212, the cables can be prepared for welding.

[0030] The welding device includes a hollow block 31, an insert block 32, a U-shaped block 33 and a No. 3 spring 34.

By moving the parcel rack 211, the outer wall of the parcel rack 211 contacts the plug block 32, so that the plug block 32 moves to the left. The movement of the plug block 32 compresses the No. 3 spring 34. When the docking groove of the parcel rack 211 and the plug block 32 are at the same level, the No. 3 spring 34 is released and drives the plug block 32 to be inserted into the docking groove, so as to achieve the docking of the parcel rack 211 and the welding rack 212, and prevent the welding material from leaking therefrom due to the poor fit of the docking, thereby damaging the cable or the device. At this time, the welding material is added from the top of the welding rack 212, and the welding gun 3 is driven by the robot arm 2 to insert The welding gun 3 is inserted into the welding frame 212, and the position of the welding gun 3 is positioned by the positioning sleeve 37. The welding gun 3 is used to weld the cables on both sides. After the welding cooling is completed, the pin 36 is pressed to make the pin 36 contact with the inclined surface of the T-shaped block 35, so that the T-shaped block 35 moves to the left. The movement of the T-shaped block 35 drives the U-shaped block 33 to move. The movement of the U-shaped block 33 will stretch the No. 3 spring 34. When the No. 3 spring 34 is stretched to a certain extent, it will pull the plug block 32 to move, so that the plug block 32 is out of the docking groove. At this time, the parcel frame 211 can be rotated to take out the welded cable.
