[0035] See also Figures 1 to 8In one embodiment, a rotating plate 404 is fixedly provided at one end of each of the multiple second rods 403, and a rubber pad 405 is fixedly provided on one side of each of the multiple rotating plates 404. A second spring 413 is movably provided on the outer surface of each of the multiple second rods 403. The multiple second springs 413 have elastic force. Before welding, the cable is in the middle position of the two discs 401, that is, in the middle position of the multiple rotating plates 404 connected by the two discs 401. The elastic force generated by the multiple second springs 413 squeezes the multiple rotating plates 404, further making the multiple rubber pads 405 close to the outer surface of the cable.

[0037] See also Figures 1 to 8 In one embodiment, a rotating rod 410 is provided on one side of the support plate 2 through a bearing, and pulleys 408 are fixedly sleeved on the outer surfaces of the connecting rod 211 and the rotating rod 410. The output shaft of the first motor 210 drives the connecting rod 211 to rotate clockwise, further drives one of the pulleys 408 to rotate clockwise, and drives the other pulley 408 to drive the rotating rod 410 clockwise through the belt 409.

[0038] See also Figures 1 to 8In one embodiment, the outer surfaces of the two pulleys 408 are connected by a belt 409, and a transmission rod 412 is provided at one end of the rotating rod 410 through a one-way bearing 411.

When the rotating rod 410 rotates clockwise, the transmission rod 412 rotates clockwise along with the rotating rod 410. When the one-way bearing 411 rotates clockwise, the outer The outer ring and the inner ring rotate in the same direction, and the rolling elements are pressed into the inclined surface or ramp between the inner and outer rings to form an effective meshing. At this time, the rotation of the outer ring is transmitted to the inner ring through the rolling elements, so that the inner ring rotates with the outer ring to complete the power transmission. When the rotation direction is counterclockwise, the rolling elements will slide away from the meshing surface between the inner and outer rings due to the action of the stopping structure, resulting in the rotation of the outer ring cannot be transmitted to the inner ring, the inner ring remains stationary, and the reverse motion is prevented. At this time, the one-way bearing 411 is in a "disconnected" state and cannot transmit reverse power. This is the existing technology and will not be described in detail here.

[0039] Working principle: When welding the cable and the internal steel belt, the cable to be welded is placed in the middle position of the two discs 401. During welding, the welded section of the cable is below the laser welding head 305. At this time, turn on the external power switch of the first motor 210, and the output shaft of the first motor 210 can rotate forward and reverse. Controlling the counterclockwise rotation further drives the threaded rod 206 to rotate counterclockwise through the connecting rod 211. The two connecting blocks 209 can slide on the inner walls of the two limit grooves 208 respectively, and then when the threaded rod 206 rotates in different directions, the circular plate 207 can move up and down on the inner wall of the threaded rod 206, and the circular plate 207 can slide on the inner wall of the cylinder 205. At this time, the threaded rod 206 rotates counterclockwise, causing the circular plate 207 to slide downward inside the cylinder 205, so that the laser welding head 305 contacts the cable welding part, and in the process of the circular plate 207 moving downward, it will push the cylinder 205 The gas under the circular plate 207 transports the gas to the inside of the two guide tubes 212, and further pushes the gas to the inside of the two diversion tubes 213, and squeezes the gas into the inside of the multiple hollow cylinders 201 through the two ends of the two diversion tubes 213. The multiple push rods 202 can slide in the inside of the multiple hollow cylinders 201 respectively. At this time, the multiple push rods 202 are squeezed by the gas, so that the two pressure plates 203 move relative to each other. When the laser welding head 305 contacts the welding position of the cable, the two pressure plates 203 press on the surface of the cable, so that the steel belt and the cable are in close contact. After the welding is completed, the output shaft of the first motor 210 is controlled to rotate clockwise. At this time, the multiple push rods 202 are not squeezed by the gas, and the elastic force of the multiple first springs 204 pulls the multiple push rods 202, so that the two pressure plates 203 release the pressure on the cable, so that when the cable and the steel belt are welded, the cable and the steel belt are pressed tightly, thereby improving the welding quality, and the pressing method is simple; During welding, the cable and the steel strip are welded by the laser welding head 305, and the circular plate 207 moves downward and drives the adjustment box 301 to move downward through the two bottom rods 3, so that the laser welding head 305 can contact the welding position, and the two slides 306 can slide on both sides of the inner wall of the adjustment box 301, and then when the screw rod 302 rotates in different directions, the sleeve 303 moves to different positions on the outer surface of the screw rod 302, and the screw rod 302 is driven to rotate in different directions by controlling the output shaft of the second motor 307, so that the sleeve 303 can drive the mounting plate 304 to move, and further, multiple positions of the cable can be welded. Therefore, when using the welding auxiliary device, the laser welding head 305 can be moved, which is convenient for welding different positions of the cable and the steel strip; After a section of welding of the cable and the steel belt is completed, the output shaft of the first motor 210 drives the connecting rod 211 to rotate clockwise, further driving one of the pulleys 408 to rotate clockwise, and the other pulley 408 drives the rotating rod 410 clockwise through the belt 409. The rotating rod 410 is connected to the transmission rod 412 through the one-way bearing 411, and then when the rotating rod 410 rotates counterclockwise, the transmission rod 412 does not rotate. When the rotating rod 410 rotates clockwise, the transmission rod 412 rotates clockwise along with the rotating rod 410. At this time, the rotating rod 410 drives the transmission rod 412 to rotate clockwise, further causing one of the discs 401 to rotate clockwise, further causing the first support rod 4 connected thereto to rotate, and then causing one of the second support rods 406 to rotate clockwise, and driving another gear 407 to rotate through one of the gears 407, so that the two discs 401 rotate in opposite directions, and multiple second sets of rods 403 can be respectively arranged at multiple first The sleeve rod 402 slides on the inner wall, and the multiple second springs 413 have elastic force. Before welding, the cable is in the middle position of the two discs 401, that is, in the middle position of the multiple rotating plates 404 connected by the two discs 401. The elastic force generated by the multiple second springs 413 squeezes the multiple rotating plates 404, further making the multiple rubber pads 405 close to the outer surface of the cable. The multiple rubber pads 405 are soft and protect the outer surface of the cable. When the two discs 401 rotate in opposite directions, the multiple rotating plates 404 rotate along with the two discs 401, further pushing the cable toward the laser welding head 305 side. After a section of the cable is welded, the two pressure plates 203 release the pressure on the cable. At the same time, the cable is pushed by the multiple rubber pads 405 to move the welded section forward, so that the subsequent welding part is placed under the laser welding head 305 for welding processing, thereby reducing manual labor and improving overall production efficiency when using the welding auxiliary device.
