[0002] In the processing of cable harnesses, it is often necessary to weld multiple harnesses together. The traditional harness production process is to transfer the products to the next heat shrink process after all products in the current batch are welded. The process is cumbersome, and the positioning of the heat shrink tube needs to be adjusted manually during heat shrinkage. There is a risk that the heat shrink tube and the welding point are not centered, resulting in quality risks. The traditional operation method is to manually heat the heat shrink tube. Therefore, in actual production, manual transfer is required in the two processes of harness welding and heat shrinkage, which affects production efficiency;
[0003] The uniformity of product quality cannot be guaranteed during mass production, and manual operation is prone to poor yield rate. Manual transfer of wiring harnesses is also prone to entanglement and damage to cables. At the same time, multiple transfers increase production time, resulting in low production efficiency. In order to improve the yield rate of products and reduce the transfer process, a welding heat shrink device that can solve the above problems is needed. Utility Model Content

[0025] The invention also includes a frame 3, and first linear guide rails 4 are fixedly connected to both sides of the frame 3. Clamps 5 are arranged on both sides of the frame 3 and are symmetrically arranged.

[0026] The centering mechanism 14 also includes a second linear guide 141, which is perpendicular to the first linear guide 4 and parallel to the horizontal plane. There are two positioning plates 143, which are symmetrically arranged on the left and right. Each positioning plate 143 is slidably connected to the second linear guide 141. When in use, the positioning plates 143 on the left and right sides slide in opposite directions at the same time. When the two positioning plates 143 are close to each other, the heat shrink tube on the outside of the wiring harness is pushed to the outside of the welding position in the middle of the wiring harness. A positioning boss 144 is fixedly connected to one side of each positioning plate 143 close to the guide plate 142. Two symmetrical guide grooves 145 are provided in the middle of the guide plate 142. The two guide grooves 145 form a certain angle with the bottom of the positioning plate 143. Each positioning boss 144 is placed in a corresponding guide groove 145. A pushing member is provided on one side of the guide plate 142. 146, the pushing member 146 can be a component that can achieve linear sliding, such as a cylinder, a hydraulic cylinder or a linear motor. The pushing member 146 is fixedly connected to the frame 3, and the output end of the pushing member 146 is fixedly connected to the guide plate 142. Each of the thumbwheels 140 is rotatably connected to the corresponding positioning plate 143. When in use, the pushing member 146 pushes the guide plate 142 to slide, and at the same time, each of the positioning bosses 144 slides along the corresponding guide groove 145, and due to the limitation of the second linear guide rail 141, the two positioning plates 143 are close to each other, and at the same time, the thumbwheel 140 pushes the heat shrink tube on the outside of the cable to be placed in the middle of the cable, and the heat shrink tube is sleeved on the welding position of the cable, and then the pushing member 146 is reset to synchronize the reset of the positioning plate 143. During use, when the cable passes the position of the thumbwheel 140, the thumbwheel 140 is rotated a certain angle to ensure that the heat shrink tube is in contact with the thumbwheel 140.

A second conveyor belt 95 is set between each of the second active pulley 91 and the corresponding second driven pulley 93. The first conveyor belt 94 and the first conveyor belt 94 are both toothed belts to ensure a good synchronization effect. During use, the motor causes the first active pulley 90 and the second active pulley 91 on the left and right sides to rotate simultaneously. At this time, the first driven pulley 92 and the second driven pulley 95 are driven by the first conveyor belt 94 and the second conveyor belt 95. The pulley 93 rotates, while ensuring that the first conveyor belt 94 and the second conveyor belt 95 have the same travel speed. Each of the first conveyor belts 94 corresponds to the corresponding second conveyor belt 95 in position.

The lower end of the oblique push member 12 is fixedly connected to the clamping jaw 5. When in use, the clamping jaw 5 clamps the cable, and then the oblique push member 12 pulls the clamping jaw 5 to move upward by one end. At the same time, the cable welding position is the same distance from the two clamping jaws 5. Then the push-pull member 10 makes the oblique push member 12 slide along the first linear guide rail 4 to place the cable into the conveying mechanism 9. Then the clamping jaw 5 releases the cable, and then the push-pull member 10, the oblique push member 12 and the clamping jaw 5 are reset to prepare for the next work.

The welding table 1 can be installed or not according to the use requirements, and the welding table 1 and the frame 3 are detachably connected by bolts and other connecting parts.
[0033] The working process of the utility model is as follows: when the welding table 1 is installed during use, the cable welding position is placed at the front end of the welding end 2, and the cable welding position is placed in the middle of the welding end 2, and a heat shrink tube of suitable diameter is set on the outside of the cable, and then the welding table 1 is operated to make the welding end 2 perform ultrasonic welding on the end of the wire harness, and then the two ends of the cable are placed in the clamping position of the clamp 5. When the welding table 1 is not installed, the welded cable can be directly put into the clamping position of the clamp 5, and the welding position is at the same distance from the clamps 5 on both sides, and the clamps 5 are controlled to clamp the cable, and then the oblique pusher 12 pulls the clamp 5 to move one end distance upward, and at the same time, the cable welding position is at the same distance from the two clamps 5, and then the push-pull member 10 makes the oblique pusher 12 slide along the first linear guide rail 4, and the cable is placed in the conveying mechanism 9, and the cable enters the gap between the first conveyor belt 94 and the second conveyor belt 95, and then is clamped by the first conveyor belt 94 and the second conveyor belt 95 and moves away from the welding table 1 The first conveyor belt 94 and the second conveyor belt 95 are pressed against the guide plate 142 to prevent the cable from falling off. When the cable passes the position of the thumbwheel 140, the thumbwheel 140 is rotated at a certain angle to ensure that the heat shrink tube contacts the thumbwheel 140. Then the pusher 146 pushes the guide plate 142 to slide. At the same time, each of the positioning bosses 144 slides along the corresponding guide groove 145. Due to the limitation of the second linear guide rail 141, the two positioning plates 143 are close to each other. At the same time, the thumbwheel 140 pushes the heat shrink tube outside the cable to be placed in the middle of the cable, and the heat shrink tube is sleeved on the welding position of the cable. Then the pusher 146 is reset to reset the positioning plate 143 synchronously. Then the conveying mechanism 9 continues to operate to move the cable. The first conveyor belt 94 and the second conveyor belt 95 move the cable and pass through the heating part of the heating plate 13. Then the heat shrink tube shrinks due to the heat and wraps the welding position of the cable. Then the cable is conveyed to the other end of the device and then falls off from the conveying mechanism 9.
