Description

Technical Field

[0001] The present invention relates to the technical field of automotive wiring harness production equipment, and specifically to a welding processing equipment for a new energy battery pack wiring harness assembly. Background Art

[0002] Automotive wiring harness welding processing equipment is mainly used to connect automotive wires, connectors and other components through welding technology. Common equipment includes ultrasonic welding machines, etc. They can ensure high-efficiency and precise connection quality, improve production efficiency, and meet the strict requirements of the automotive industry for safety and durability.

[0003] A Chinese patent with the patent publication number CN212977105U discloses an ultrasonic welding device for automotive wiring harness production, specifically relating to the technical field of automotive wiring harness production equipment, including a workbench, a pressing table, pillars and a top plate. Clamping structures are fixedly connected to both ends and one side of the top of the workbench. A pressing table is fixedly connected to the middle position of the top of the workbench, and a protective structure is fixedly connected to the top of the pressing table. Pillars are fixedly connected to both sides at one end of the top of the workbench, and a top plate is fixedly connected between one sides of the tops of the pillars. An hydraulic cylinder is fixedly connected to the middle position of the bottom end of the top plate, and an hydraulic expansion rod is fixedly connected to the output end of the hydraulic cylinder. An ultrasonic generator is fixedly connected to the bottom end of the hydraulic expansion rod. Heat dissipation mechanisms are fixedly connected to both sides of the top of the workbench. This patent prevents the wiring harness from being displaced under the high-frequency vibration of the pressing block by fixedly connecting clamping structures to both ends and one side of the top of the workbench, thus improving the precision of welding.

[0004] However, the current welding equipment has the following problems: This welding equipment requires manual holding of the wiring harness for welding, which poses a great safety hazard. Moreover, manual operation requires more time to adjust and position the wiring harness, resulting in inconsistent quality of each wiring harness solder joint and making it difficult to ensure high standards of the product. Therefore, we propose a support and fixing device for a land surveying instrument. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a welding processing equipment for a new energy battery pack wiring harness assembly, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A welding processing device for a new energy battery pack wire harness assembly, including a processing table, on one side of the top of the processing table, an ultrasonic welding device main body is fixed. In the center of the top of the processing table, a placement table is fixed. A semi-automatic device is arranged at the placement table. The semi-automatic device includes a double-shaft motor, an L-shaped plate, and an L-shaped frame. The double-shaft motor is fixedly installed in the middle of the placement table through a bracket. Link rods are fixed to both output ends of the double-shaft motor. Notch rings are fixed to the exteriors of the two link rods, and four semi-circular notches are formed on the exteriors of the notch rings. The L-shaped frame is fixed to the top of the processing table. A semi-circular plate is fixed to the top of the L-shaped frame. The L-shaped plate is fixed to the top of the processing table. The L-shaped plate is located on the side of the notch ring away from the ultrasonic welding device main body. The semi-circular plate is located above the notch ring and is concentric with the notch ring. The double-shaft motor drives the notch ring to rotate through the link rod. The semi-circular notches of the notch ring drive the wire harness to rotate upward. At the same time, during this process, the semi-circular plate will block the outside of the semi-circular notches of the notch ring, so that the semi-circular plate restricts the wire harness in the semi-circular notches of the notch ring. Then, the wire harness will be rotated to the area below the welding end of the ultrasonic welding device main body.

[0007] According to the above technical solution, two positioning rods are fixed to the top of the semi-circular plate. A trapezoidal pressing plate is slidably installed between the outer walls of the two positioning rods. A spring is arranged between the trapezoidal pressing plate and the positioning rods. The bottom of the trapezoidal pressing plate penetrates the top of the semi-circular plate. Every time the semi-circular notch of the notch ring drives the wire harness to rotate to the inclined surface position of the trapezoidal pressing plate, the wire harness will push the inclined surface of the trapezoidal pressing plate to drive the trapezoidal pressing plate to move upward. Then, under the elastic force of the spring corresponding to the trapezoidal pressing plate, the trapezoidal pressing plate will press on the rubber skin part of the wire harness.

[0008] According to the above technical solution, the placement table includes a U-shaped table, a U-shaped baffle, and an electric push rod. The U-shaped table is fixed to the top of the processing table. The electric push rod is fixed to the bottom of the processing table. The U-shaped baffle is fixed to the top of the telescopic end of the electric push rod and is slidably installed inside the U-shaped table. The U-shaped baffle vertically penetrates the U-shaped table. Rounded corners are provided on both sides of the top of the U-shaped table. The top of the U-shaped baffle is provided with rounded corners adapted to the rounded corners of the U-shaped table. It is worth noting that before the ultrasonic welding device main body performs welding operations, the telescopic end of the electric push rod will push the U-shaped baffle upward, and the U-shaped baffle will form a retaining edge on both sides of the U-shaped table. That is, when the placement table performs welding operations, there will be retaining edges on both sides of the placement table to restrict the wire harness.

[0009] According to the above technical solution, a leather pushing device is provided on the side of the placing table away from the ultrasonic welding equipment main body. The leather pushing device includes two reciprocating screw cylinders, two threaded rings, two Z-shaped rods, and two arc push rods. The two reciprocating screw cylinders are respectively fixed outside the two output ends of the double-shaft motor. The two threaded rings are respectively threadedly connected to the outside of the two reciprocating screw cylinders. The two Z-shaped rods are respectively fixed to the outside of the two threaded rings. The two arc push rods are respectively fixed to one end of the two Z-shaped rods away from the threaded rings. And the two arc push rods are both slidably installed on the side of the U-shaped table away from the ultrasonic welding equipment main body. The arc push rod is concentric with the notch ring, and the arc push rod protrudes one centimeter from the semi-circular notch of the notch ring. After the wire harnesses are respectively placed in the semi-circular notches of the two notch rings, at this time the wire harnesses are also in the semi-circular plate. During the rotation of the output end of the double-shaft motor, the reciprocating screw cylinder will also be driven to rotate. During the process that the double-shaft motor drives the wire harness in the notch ring to rotate to 45 degrees through the connecting rod, the reciprocating screw cylinder will drive the threaded ring to drive the Z-shaped rod and the arc push rod to move towards the notch ring. During the movement of the arc push rod, it will push the rubber skin part of the wire harness to be flush with the side of the notch ring.

[0010] According to the above technical solution, the leather pushing device further includes two hinge rods, a semi-arc plate, an elastic telescopic plate, a U-shaped track plate, and an arc pressing plate. The U-shaped track plate is fixed to the side of the placing table away from the ultrasonic welding equipment main body. The fixed end of the elastic telescopic plate is slidably installed inside the U-shaped track plate. The semi-arc plate is fixed to the side of the fixed end of the elastic telescopic plate away from the placing table. The arc pressing plate is fixed to the top of the arc pressing plate. One end of each of the two hinge rods is respectively hinged to the top of the two Z-shaped rods, and the other end of each of the two hinge rods is respectively hinged to the top of the telescopic end of the elastic telescopic plate. At the same time, during the movement of the Z-shaped rod towards the notch ring, the Z-shaped rod pulls the hinge rod to drive the elastic telescopic plate to move along the inside of the U-shaped track plate towards the placing table. The elastic telescopic plate drives the arc pressing plate to move along with the semi-arc plate, so that the arc pressing plate pre-presses the overlapping part of the two wire harnesses to be welded.

[0011] According to the above technical solution, a stabilizing device is provided inside the notch ring. The stabilizing device includes two fixing rings, two track circular grooves, eight sliding columns, eight sliding plates, and sixteen elastic plates. The two fixing rings are respectively fixed on both sides of the placement table. The two track circular grooves are respectively opened on the sides of the two fixing rings away from each other. The eight sliding plates respectively penetrate and are slidably installed on the inner walls of the two notch rings. One ends of the eight sliding columns are respectively fixed on the sides of the eight sliding plates close to the placement table. The other ends of the eight sliding columns are respectively slidably installed inside the two track circular grooves. The sixteen elastic plates are respectively fixed on both sides of the eight sliding plates away from the center of the notch ring. A receiving groove for receiving the elastic plates is opened on the inner wall of the semi-circular notch of the notch ring. The middle part of the side of the track circular groove away from the L-shaped frame is a small arc groove. The upper part of the track circular groove is an upper semi-arc groove one centimeter smaller than the small arc groove. The lower part of the track circular groove is a lower semi-arc groove two centimeters larger than the small arc groove. During the process of the wire harness rotating from zero degree to ninety degrees in the notch ring, the notch ring will drive the sliding column to move from the small arc groove of the track circular groove to the upper semi-arc groove of the track circular groove through the sliding plate. At this time, the sliding column drives the sliding plate to move towards the center of the notch ring, and the sliding plate drives the elastic plate to move along. The edge of the through-hole of the sliding plate and the notch ring will squeeze the elastic plate, and the elastic plate will warp and clamp the wire harness in the semi-circular notch of the notch ring. During the process of the wire harness rotating from one hundred and eighteen degrees to zero degree in the notch ring, the notch ring will drive the sliding column to move from the upper semi-arc groove of the track circular groove to the lower semi-arc groove of the track circular groove through the sliding plate. At this time, the sliding column drives the sliding plate to move away from the center of the notch ring, and the sliding plate will push the welded wire harness in the semi-circular notch of the notch ring out of the semi-circular notch of the notch ring.

[0012] The present invention provides a welding and processing device for a wire harness assembly of a new energy battery pack. It has the following beneficial effects:

[0013] (1) Through the setting of the semi-automatic device, the present invention enables the cooperation of the dual-axis motor, the connecting rod, the notch ring, and the semi-circular plate to weld the wire harness in a semi-automatic manner, avoiding the problem that the quality of each wire harness welding point is inconsistent due to manual adjustment and positioning of the wire harness, thereby improving the quality of wire harness welding; at the same time, the trapezoidal pressing plate will press on the rubber skin part of the wire harness, and appropriate pressing can help prevent the wire harness from shifting during welding and avoid affecting the subsequent welding effect.

[0014] (2) Through the setting of the leather pushing device in the present invention, the notch ring, semi-circular plate, double-shaft motor, reciprocating screw barrel, connecting rod, and threaded ring drive the Z-shaped rod to cooperate with the arc push rod to push the rubber skin part of the wire harness to be flush with the side of the notch ring, thereby avoiding the problem that during the placement of the wire harness, due to human error, the rubber skin part of the wire harness is located below the welding area of the main body of the ultrasonic welding equipment, resulting in the failure of wire harness welding. Furthermore, it helps to provide a stable position during each wire harness welding process, thereby reducing the influence of human error and improving the consistency and reliability of welding. At the same time, the L-shaped frame, notch ring, hinge rod, elastic telescopic plate, and semi-arc plate cooperate to drive the arc pressing plate to pre-profile the overlapping parts of the two wire harnesses to be welded. Through pre-profiling, the arc pressing plate can ensure that the contact surfaces of the two wire harnesses are flat and consistent, which enables the wire harnesses to obtain better contact during welding, ensures uniform heat transfer, and thus improves the welding quality.

[0015] (3) Through the setting of the stabilizing device in the present invention, during the process of the wire harness rotating from zero degrees to ninety degrees in the notch ring, the notch ring, sliding plate, sliding column, track circular groove, and sliding plate cooperate to drive the elastic plate to warp and clamp the wire harness in the semi-circular notch of the notch ring, thereby further improving the stability of the wire harness in the semi-circular notch of the notch ring and avoiding the problem of displacement during the rotation of the notch ring driving the wire harness. During the process of the wire harness rotating from one hundred and eighteen degrees to zero degrees in the notch ring, the notch ring, sliding plate, sliding column, track circular groove, and sliding plate cooperate to drive the sliding plate to push the welded wire harness in the semi-circular notch of the notch ring out of the semi-circular notch of the notch ring, thereby avoiding the problem that the wire harness is stuck in the semi-circular notch of the notch ring during the discharge process, affecting the operation of the welding processing equipment.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Please refer to Figure 1 - Figure 9, an embodiment of the present invention is: a welding processing device for a new energy battery pack wiring harness assembly, including a processing table 1. On one side of the top of the processing table 1, an ultrasonic welding device main body 2 is fixedly installed. In the center of the top of the processing table 1, a placement table 3 is fixedly installed. A semi-automatic device 4 is arranged at the placement table 3. The semi-automatic device 4 includes a double-shaft motor 41, an L-shaped plate 44, and an L-shaped frame 45. The double-shaft motor 41 is fixedly installed in the middle of the placement table 3 through a bracket. On both output ends of the double-shaft motor 41, connecting rods 42 are fixedly installed. On the outer parts of the two connecting rods 42, notch rings 43 are fixedly installed. Four semi-circular notches are opened on the outer part of the notch ring 43. The L-shaped frame 45 is fixedly installed on the top of the processing table 1. On the top of the L-shaped frame 45, a semi-circular plate 46 is fixedly installed. The L-shaped plate 44 is fixedly installed on the top of the processing table 1. The L-shaped plate 44 is located on the side of the notch ring 43 away from the ultrasonic welding device main body 2. The semi-circular plate 46 is located above the notch ring 43, and the semi-circular plate 46 and the notch ring 43 are concentrically arranged. The two wiring harnesses to be butt-welded are respectively placed into the semi-circular notches of the two notch rings 43, and the welding points of the two wiring harnesses are overlapped with each other. The double-shaft motor 41 is started. The double-shaft motor 41 drives the notch ring 43 to rotate through the connecting rod 42. The semi-circular notches of the notch ring 43 drive the wiring harness to rotate upward. At the same time, during this process, the semi-circular plate 46 will block the outside of the semi-circular notches of the notch ring 43, so that the semi-circular plate 46 restricts the wiring harness in the semi-circular notches of the notch ring 43. Then, the wiring harness will be rotated to the area below the welding end of the ultrasonic welding device main body 2. At this time, the double-shaft motor 41 is stopped, and the ultrasonic welding device main body 2 is started to perform welding operations on the wiring harness. After the wiring harness is welded, the double-shaft motor 41 is started again. The semi-circular notches of the notch ring 43 will drive the welded wiring harness out of the semi-circular plate 46. At this time, the welded wiring harness can fall out of the semi-circular notches of the notch ring 43.

[0028] Two positioning rods 47 are fixedly installed on the top of the semi-circular plate 46. A trapezoidal pressing plate 48 is slidably installed between the outer walls of the two positioning rods 47. A spring is arranged between the trapezoidal pressing plate 48 and the positioning rods 47. The bottom of the trapezoidal pressing plate 48 penetrates through the top of the semi-circular plate 46. Through the setting of the above structure, the trapezoidal pressing plate 48 will press on the rubber skin part of the wiring harness. Appropriate pressing can help prevent the wiring harness from shifting during the welding process and avoid affecting the subsequent welding effect.

[0029] The placement table 3 includes a U-shaped table 31, a U-shaped baffle 32, and an electric push rod 33. The U-shaped table 31 is fixed to the top of the processing table 1, the electric push rod 33 is fixed to the bottom of the processing table 1, the U-shaped baffle 32 is fixed to the top of the telescopic end of the electric push rod 33, and the U-shaped baffle 32 is slidably installed inside the U-shaped table 31. The U-shaped baffle 32 vertically penetrates the U-shaped table 31. Rounded corners are provided on both sides of the top of the U-shaped table 31, and rounded corners adapted to the rounded corners of the U-shaped table 31 are provided on the top of the U-shaped baffle 32. Before the ultrasonic welding equipment main body 2 performs welding operations, the telescopic end of the electric push rod 33 will push the U-shaped baffle 32 upward, and the U-shaped baffle 32 will form retaining edges on both sides of the U-shaped table 31. That is, when the placement table 3 performs welding operations, there will be retaining edges on both sides of the placement table 3 to restrict the wire harness.

[0030] A leather pushing device 5 is provided on the side of the placement table 3 away from the ultrasonic welding equipment main body 2. The leather pushing device 5 includes two reciprocating lead screw cylinders 51, two threaded rings 52, two Z-shaped rods 53, and two arc push rods 54. The two reciprocating lead screw cylinders 51 are respectively fixed to the outer sides of the output ends on both sides of the double-shaft motor 41. The two threaded rings 52 are respectively threadedly connected to the outsides of the two reciprocating lead screw cylinders 51. The two Z-shaped rods 53 are respectively fixed to the outsides of the two threaded rings 52. The two arc push rods 54 are respectively fixed to the ends of the two Z-shaped rods 53 away from the threaded rings 52, and the two arc push rods 54 are both slidably installed on the side of the U-shaped table 31 away from the ultrasonic welding equipment main body 2. The arc push rod 54 is concentric with the notch ring 43, and the arc push rod 54 protrudes one centimeter from the semi-circular notch of the notch ring 43. Through the setting of the above structure, the rubber skin part of the wire harness is pushed to be flush with the side of the notch ring 43 during the movement of the arc push rod 54, thus avoiding the problem that the rubber skin part of the wire harness is located below the welding area of the ultrasonic welding equipment main body 2 due to human error during the wire harness placement process, resulting in wire harness welding failure. Furthermore, it helps to provide a stable position during each wire harness welding process, thereby reducing the influence brought by human errors and improving the consistency and reliability of welding.

[0031] The leather pushing device 5 further includes two hinge rods 55, a semi-circular plate 56, an elastic telescopic plate 57, a U-shaped track plate 58, and an arc pressing plate 59. The U-shaped track plate 58 is fixed to the side of the U-shaped table 31 away from the ultrasonic welding equipment main body 2. The fixed end of the elastic telescopic plate 57 is slidably installed inside the U-shaped track plate 58. The semi-circular plate 56 is fixed to the side of the fixed end of the elastic telescopic plate 57 away from the placing table 3. The arc pressing plate 59 is fixed to the top of the arc pressing plate 59. One ends of the two hinge rods 55 are respectively hinged to the tops of the two Z-shaped rods 53, and the other ends of the two hinge rods 55 are respectively hinged to the top of the telescopic end of the elastic telescopic plate 57. Through the setting of the above structure, the overlapping part of the two wire harnesses to be welded is pre-shaped by the arc pressing plate 59. Through pre-shaping, the arc pressing plate 59 can ensure that the contact surfaces of the two wire harnesses are flat and consistent, which enables the wire harnesses to obtain better contact during welding, ensures uniform heat transfer, and thus improves the welding quality.

[0032] During use, the two wire harnesses to be butt-welded are respectively placed into the semi-circular recesses of the two notch rings 43, and the welding points of the two wire harnesses are overlapped with each other. The double-shaft motor 41 is started. The double-shaft motor 41 drives the notch ring 43 to rotate through the connecting rod 42. The semi-circular recess of the notch ring 43 drives the wire harness to rotate upward. At the same time, during this process, the semi-circular plate 46 will block the outside of the semi-circular recess of the notch ring 43, so that the semi-circular plate 46 restricts the wire harness in the semi-circular recess of the notch ring 43. Then, the wire harness will be rotated to the area below the welding end of the ultrasonic welding equipment main body 2. At this time, the double-shaft motor 41 is stopped, and the ultrasonic welding equipment main body 2 is started to perform welding operations on the wire harness. After the wire harness is welded, the double-shaft motor 41 is started again. The semi-circular recess of the notch ring 43 will drive the welded wire harness out of the semi-circular plate 46. At this time, the welded wire harness can fall out of the semi-circular recess of the notch ring 43. It should be noted that before the ultrasonic welding equipment main body 2 performs welding operations, the telescopic end of the electric push rod 33 will push the U-shaped baffle 32 upward. The U-shaped baffle 32 will form a retaining edge on both sides of the U-shaped table 31, that is, when the placing table 3 performs welding operations, there will be retaining edges restricting the wire harness on both sides of the placing table 3. By welding the wire harness in the above semi-automatic manner, the problem that manual adjustment and positioning of the wire harness are required, resulting in inconsistent quality of each wire harness welding point, is avoided, and thus the quality of wire harness welding is improved; every time the semi-circular recess of the notch ring 43 drives the wire harness to rotate to the inclined surface position of the trapezoidal pressing plate 48, the wire harness will push the inclined surface of the trapezoidal pressing plate 48 to drive the trapezoidal pressing plate 48 to move upward. Then, under the action of the spring force corresponding to the trapezoidal pressing plate 48, the trapezoidal pressing plate 48 will press on the rubber skin part of the wire harness. Appropriate pressing can help prevent the wire harness from shifting during welding and avoid affecting the subsequent welding effect.

[0033] After the wire harnesses are respectively placed into the semi-circular recesses of the two notch rings 43, at this time the wire harnesses are also in the semi-circular plate 46. During the rotation of the output end of the dual-axis motor 41, the reciprocating screw barrel 51 will also be driven to rotate. During the process that the dual-axis motor 41 drives the wire harnesses in the notch ring 43 to rotate to 45 degrees through the connecting rod 42, the reciprocating screw barrel 51 will drive the threaded ring 52 to drive the Z-shaped rod 53 and the arc-shaped push rod 54 to move towards the notch ring 43. During the movement of the arc-shaped push rod 54, it will push the rubber skin part of the wire harness to be flush with the side of the notch ring 43, thus avoiding the problem that during the placement of the wire harness, due to human error, the rubber skin part of the wire harness is located below the welding area of the ultrasonic welding equipment main body 2, resulting in the failure of wire harness welding. Furthermore, it helps to provide a stable position during each wire harness welding process, thereby reducing the influence brought by human error and improving the consistency and reliability of welding. It should be noted that during the process that the wire harnesses in the notch ring 43 rotate from 45 degrees to 90 degrees, at this time the reciprocating screw barrel 51 will drive the threaded ring 52 to drive the Z-shaped rod 53 and the arc-shaped push rod 54 to move back to the position away from the notch ring 43; it should also be noted that during the process that the connecting rod 42 drives the wire harnesses in the notch ring 43 to rotate to 45 degrees, the Z-shaped rod 53 will move towards the notch ring 43. At this time, the Z-shaped rod 53 pulls the articulated rod 55 to drive the elastic telescopic plate 57 to move along the inside of the U-shaped track plate 58 towards the placement table 3. The elastic telescopic plate 57 drives the arc-shaped pressing plate 59 to move along with the semi-arc plate 56, so that the arc-shaped pressing plate 59 pre-presses the overlapping part of the two wire harnesses to be welded. By pre-pressing the overlapping part of the two wire harnesses to be welded, the arc-shaped pressing plate 59 can ensure that the contact surfaces of the two wire harnesses are flat and consistent, which enables the wire harnesses to obtain better contact during welding, ensures uniform heat transfer, and thus improves the welding quality. It should also be noted that due to the certain thickness of the wire harnesses, the setting of the elastic telescopic plate 57 can prevent movement interference during the operation of the articulated rod 55 and the Z-shaped rod 53.

[0034] Please refer to Figure 1 - Figure 9 , on the basis of the above embodiment, in another embodiment of the present invention, a stabilizing device 6 is arranged on the inner side of the notch ring 43.

[0035] The fixing device 6 includes two fixing rings 61, two track circular grooves 62, eight sliding columns 63, eight sliding plates 64, and sixteen elastic plates 65. The two fixing rings 61 are respectively fixed on both sides of the U-shaped table 31. The two track circular grooves 62 are respectively opened on the sides of the two fixing rings 61 away from each other. The eight sliding plates 64 respectively penetrate and are slidably installed on the inner walls of the two notch rings 43. One ends of the eight sliding columns 63 are respectively fixed on the sides of the eight sliding plates 64 close to the placing table 3. The other ends of the eight sliding columns 63 are respectively slidably installed inside the two track circular grooves 62. The sixteen elastic plates 65 are respectively fixed on both sides of the eight sliding plates 64 away from the center of the notch ring 43. A receiving groove for receiving the elastic plate 65 is opened on the inner wall of the semi-circular notch of the notch ring 43. The middle part of the side of the track circular groove 62 away from the L-shaped frame 45 is a small arc groove. The upper half arc groove above the track circular groove 62 is one centimeter smaller than the small arc groove. The lower half arc groove below the track circular groove 62 is two centimeters larger than the small arc groove. During the process of the wire harness rotating from zero degree to ninety degrees in the notch ring 43, through the setting of the above structure, the elastic plate 65 is warped and clamps the wire harness in the semi-circular notch of the notch ring 43, thereby further improving the stability of the wire harness in the semi-circular notch of the notch ring 43 and avoiding the problem of displacement during the rotation of the notch ring 43 driving the wire harness. During the process of the wire harness rotating from one hundred and eighteen degrees to three hundred and sixty degrees (i.e., continuing to rotate back to the starting point) in the notch ring 43, through the setting of the above structure, the sliding plate 64 pushes the welded wire harness in the semi-circular notch of the notch ring 43 out of the semi-circular notch of the notch ring 43, thereby avoiding the problem that the wire harness is stuck in the semi-circular notch of the notch ring 43 during the discharge process and affecting the operation of the welding processing equipment.

[0036] During use, during the process of the wire harness rotating from zero degree to ninety degrees in the notch ring 43, the notch ring 43 will drive the sliding column 63 to move from the small arc groove of the track circular groove 62 to the upper half arc groove of the track circular groove 62 through the sliding plate 64. At this time, the sliding column 63 drives the sliding plate 64 to move towards the center of the notch ring 43, and the sliding plate 64 drives the elastic plate 65 to move accordingly. The edge of the through-hole of the sliding plate 64 and the notch ring 43 will squeeze the elastic plate 65, and the elastic plate 65 is warped and clamps the wire harness in the semi-circular notch of the notch ring 43, thereby further improving the stability of the wire harness in the semi-circular notch of the notch ring 43 and avoiding the problem of displacement during the rotation of the notch ring 43 driving the wire harness. During the process of the wire harness rotating from one hundred and eighteen degrees to three hundred and sixty degrees (i.e., continuing to rotate back to the starting point) in the notch ring 43, the notch ring 43 will drive the sliding column 63 to move from the upper half arc groove of the track circular groove 62 to the lower half arc groove of the track circular groove 62 through the sliding plate 64. At this time, the sliding column 63 drives the sliding plate 64 to move away from the center of the notch ring 43, and the sliding plate 64 will push the welded wire harness in the semi-circular notch of the notch ring 43 out of the semi-circular notch of the notch ring 43, thereby avoiding the problem that the wire harness is stuck in the semi-circular notch of the notch ring 43 during the discharge process and affecting the operation of the welding processing equipment.
