[0025] Embodiment 2, on the basis of embodiment 1, positioning support plates 2 are installed on both sides of the top of the fixed operating table 1; support plates 201 are installed on the top of the two positioning support plates 2; a rotating member 202 is rotatably installed on the top of the positioning column 102; the rotating member 202 is a circular structure, and the rotating member 202 is rotatably installed between the two support plates 201, and a plurality of evenly distributed positioning grooves 203 are provided on the top of the rotating member 202; a fixed vertical rod 204 is installed at the edge position of the rear side of the fixed operating table 1; a collecting plate 205 is installed on the top of the fixed vertical rod 204; a driving motor is installed in the middle position of the front side of the top of the collecting plate 205, and a driving rod 206 is installed on the output end of the driving motor; the bottom of the driving rod 206 is connected to the middle position of the rotating member 202; the positioning groove A positioning rod 207 is installed inside 203; a fixed cover 1 208 and a fixed cover 209 are rotatably installed on the outer side of the positioning rod 207; the tops of the fixed cover 1 208 and the fixed cover 209 form an encircling state, and the bottoms of the fixed cover 1 208 and the fixed cover 209 are connected to the side walls of the positioning groove 203 through springs; a driving cylinder is installed on the top rear side of the collecting plate 205, and a traction vertical plate 2010 is installed on the output end of the driving cylinder; a guide bracket 2011 is installed at the bottom of the traction vertical plate 2010; a guide rod 2012 is installed on the inner side of the guide bracket 2011; a protrusion is provided on the outer side of the guide rod 2012, and a return spring is installed on the outer ring of the guide rod 2012, and a support carrier 2013 is slidably installed on the outer side of the guide rod 2012;The bottom of the support carrier 2013 is connected to the return spring on the outside of the guide rod 2012. The support carrier 2013 is slidably installed at the bottom of a positioning cover 108. When the switch harness is positioned and welded, the drive motor on the collection plate 205 at the top of the fixed vertical rod 204 works, and the output end of the drive motor drives the drive rod 206 to pull the rotating member 202 to rotate on the top of the positioning column 102, and the fixed cover 1 208 and the fixed cover 209 are moved on the positioning rod 207 inside the positioning groove 203. The outer side of the switch harness is rotated so that the surrounding state formed by the fixed cover 1 208 and the fixed cover 209 is used to position the terminal part of the switch harness. The springs at the bottom of the fixed cover 1 208 and the fixed cover 209 provide clamping force to ensure the stability of the clamping positioning. The rotating member 202 drives the clamped switch harness terminal to rotate so that the unwelded switch harness terminal moves to the bottom of the welding gun assembly 305 and is aligned with the positioned wire. The positioning support plate 2 drives the support plate 201 to isolate and lift the welded harness so that the welded switch harness can be The wiring harness drives the wire to move on the support plate 201. When the switch wiring harness is welded, the output end of the drive cylinder at the top of the assembly plate 205 drives the support carrier 2013 on the guide rod 2012 inside the guide bracket 2011 to move to the bottom of a positioning cover 108. After the welding is completed, when the positioning cover 108 moves downward, the support carrier 2013 first provides a resistance to the downward movement of the positioning cover 108. When the guide push plate 107 pushes the sheet-like splint 1010 to move to both sides, the downward pressure generated by the guide slide 105 and the guide push plate 107 drives the positioning cover 108 to push the support carrier 2013 downward to a suitable distance. At this time, the drive cylinder drives the support carrier 2013 to move backward and loses the fixation of the positioning cover 108, which makes it easy for the wire to fall off the fixing force, so as to drive the switch wiring harness that has been welded to move. The rotating member 202 continues to rotate, driving the welded and unwelded switch wiring harness components to rotate, quickly completing the disassembly and installation operations of the switch wiring harness components, and improving the welding efficiency of the switch wiring harness. ;

When the switch wiring harness is positioned and welded, the driving assembly 304 at the bottom of the assembly plate 205 drives the welding gun assembly 305 to adjust to different angles, so that the welding gun assembly 305 can perform welding operations on different positions of the switch wiring harness, drive the pump assembly 3 to work, and the protective cover 301 blocks the rear area, so that the airflow passes through the guide tube 302 and enters the interior of the exhaust hood 303 and is ejected, so that the airflow blows away the welding slag carried by the switch wiring harness after welding to clean it.

[0027] The working principle of this embodiment is as follows: the servo motor on the top of the fixed operating table 1 drives the traction ring 104 to drive the rotating plate 103 to rotate on the positioning column 102 and the limiting protrusion on the outside thereof, and the rotating plate 103 drives the guide slide 105 and the top positioning cover 108 to move, and the single wire is placed between the two sheet-like clamps 1010. Under the action of the spring, the two sheet-like clamps 1010 position the wire along the limiting rod 109. After the rotating plate 103 drives the top positioning cover 108 to rotate, the rotating plate 103 drives the traction plate 106 at the bottom of the guide slide 105 to move to the outside of the traction member 1012, and the drive cylinder on the rear side of the fixed support leg 101 is output. The output end driving traction member 1012 drives the traction plate 106 to move upward, and the traction plate 106 drives the guide push plate 107 to push the sheet splint 1010 upward through the guide slide 105. The sheet splint 1010 drives the positioning cover 108 to move upward to a suitable height through the limit rod 109. At the same time, the driving cylinder on the rear side of the top of the collection plate 205 drives the traction vertical plate 2010 to move. The bottom of the traction vertical plate 2010 drives the support carrier 2013 on the guide rod 2012 inside the guide bracket 2011 to slide and be installed at the bottom of the positioning cover 108 to ensure the stability of the positioning cover 108. The driving motor on the collection plate 205 drives the driving rod 206 The traction rotating member 202 rotates on the top of the positioning column 102, and the fixed cover 1 208 and the fixed cover 209 are moved in the positioning groove 203 to position the terminal part of the switch harness. The rotating member 202 drives the clamped switch harness terminal to move to the bottom of the welding gun assembly 305 and connect it with the positioned wire. The driving assembly 304 at the bottom of the assembly plate 205 drives the welding gun assembly 305 to adjust different angles. The welding gun assembly 305 performs welding operations on different positions of the switch harness. After the welding is completed, the traction member 1012 drives the traction plate 106 to move downward, and the traction plate 106 drives the guide push plate 107 to move downward through the guide slide 105. At this time, Under the action of the return spring on the outside of the guide rod 2012, the support carrier 2013 initially positions the positioning cover 108. The downward movement of the guide push plate 107 will push the two sheet-like splints 1010 to move to both sides. The two sheet-like splints 1010 cancel the fixation of the wires, and the driving cylinder drives the support carrier 2013 to move outward to cancel the positioning of the positioning cover 108. The traction plate 106 continues to drive the positioning cover 108 to move downward, and the rotating part 202 drives the welded switch harness to move on the support plate 201, which is convenient for replacing the switch harness components between the idle fixed cover 1 208 and the fixed cover 209 and the two sheet-like splints 1010.
