Each time the semicircular notch of the notch ring drives the wiring harness to rotate to the inclined position of the trapezoidal pressure plate, the wiring harness will push the inclined surface of the trapezoidal pressure plate to drive the trapezoidal pressure plate to move upward, and then under the action of the spring elastic force corresponding to the trapezoidal pressure plate, the trapezoidal pressure plate will press on the rubber skin part of the wiring 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.

After the wiring harness is respectively placed in the semicircular notches of the two notch rings, the wiring harness is also in the semicircular plate. The output end of the dual-axis motor will also drive the reciprocating screw rod barrel to rotate during the rotation process. In the process of the dual-axis motor driving the wiring harness in the notch ring to rotate to forty-five degrees through the connecting rod, the reciprocating screw rod barrel will drive the threaded ring to drive the Z-shaped rod and the arc push rod to move in the direction of the notch ring.

In the process of the wiring harness in the notch ring rotating from zero degrees to ninety degrees, the notch ring will drive the sliding column 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.

In the process of the wiring harness in the notch ring rotating from one hundred and eighteen degrees to zero degrees, the notch ring will drive the sliding column 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 in the direction away from the center of the notch ring, and the sliding plate will push the welding wiring harness in the semicircular notch of the notch ring out of the semicircular notch of the notch ring.

[0012] The present invention provides a welding processing device for a new energy battery pack wiring harness assembly.

The dual-axis motor 41 is started, and the dual-axis motor 41 drives the notch ring 43 to rotate through the connecting rod 42. The semicircular notch of the notch ring 43 drives the wiring harness to rotate upward. At the same time, in this process, the semicircular plate 46 will block the outside of the semicircular notch of the notch ring 43, so that the semicircular plate 46 restricts the wiring harness in the semicircular notch of the notch ring 43. Then, the wiring harness will be rotated to the area below the welding end of the ultrasonic welding equipment body 2. At this time, the dual-axis motor 41 is stopped, and the ultrasonic welding equipment body 2 is started to weld the wiring harness. After the wiring harness is welded, the dual-axis motor 41 is started again, and the semicircular notch of the notch ring 43 will drive the welded wiring harness to move out of the semicircular plate 46.

[0021] A skin pushing device 5 is provided on one side of the placing table 3 away from the main body 2 of the ultrasonic welding equipment. The skin pushing device 5 includes two reciprocating screw rod cylinders 51, two threaded rings 52, two Z-shaped rods 53, and two arc push rods 54. The two reciprocating screw rod cylinders 51 are respectively fixed to the outside of the output ends on both sides of the dual-axis motor 41, the two threaded rings 52 are respectively threadedly connected to the outside of the two reciprocating screw rod cylinders 51, the two Z-shaped rods 53 are respectively fixed to the outside of the two threaded rings 52, and the two arc push rods 54 are respectively fixed to one end of the two Z-shaped rods 53 away from the threaded ring 52, and the two arc push rods 54 are both slidably mounted on the U-shaped table 31 away from the ultrasonic welding equipment. On one side of the equipment body 2, the arc push rod 54 is concentrically arranged with the notch ring 43, and the arc push rod 54 protrudes one centimeter from the semicircular notch of the notch ring 43. Through the arrangement of the above structure, the arc push rod 54 pushes the rubber skin part of the wire harness to be flush with the side of the notch ring 43 during the movement, thereby avoiding the problem of human error causing the rubber skin part of the wire harness to be under the welding area of ​​the ultrasonic welding equipment body 2 during the placement of the wire harness, resulting in the failure of the wire harness welding. This helps to provide a stable position during each wire harness welding process, thereby reducing the impact of human errors and improving the consistency and reliability of welding.

[0022] The skin pushing device 5 also includes two hinged rods 55, a semi-arc plate 56, an elastic telescopic plate 57, a U-shaped track plate 58, and an arc pressure plate 59. The U-shaped track plate 58 is fixed on the side of the U-shaped table 31 away from the ultrasonic welding equipment body 2. The fixed end of the elastic telescopic plate 57 is slidably installed inside the U-shaped track plate 58. The semi-arc plate 56 is fixed on the side of the fixed end of the elastic telescopic plate 57 away from the placement table 3. The arc pressure plate 59 is fixed on the top of the arc pressure plate 59. One end of the two hinged rods 55 is respectively hinged on the top of the two Z-shaped rods 53, and the other end of the two hinged rods 55 is respectively hinged on the top of the telescopic end of the elastic telescopic plate 57. Through the arrangement of the above structure, the arc pressure plate 59 pre-presses the overlapping parts of the two wire harnesses to be welded. Through pre-pressing, the arc pressure 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 welding quality.

[0023] When in use, the two wiring harnesses that need to be welded are respectively placed in the semicircular recesses of the two recessed rings 43, and the welding points of the two wiring harnesses are overlapped with each other, and the dual-axis motor 41 is started. The dual-axis motor 41 drives the recessed ring 43 to rotate through the connecting rod 42, and the semicircular recess of the recessed ring 43 drives the wiring harness to rotate upward. At the same time, in this process, the semicircular plate 46 will block the outside of the semicircular recess of the recessed ring 43, so that the semicircular plate 46 restricts the wiring harness in the semicircular recess of the recessed ring 43. Then, the wiring harness will be rotated to the area below the welding end of the ultrasonic welding equipment body 2. At this time, the dual-axis motor 41 is stopped, and the ultrasonic welding equipment body 2 is started to weld the wiring harness. After the wiring harness is welded, the dual-axis motor 41 is started again, and the semicircular recess of the recessed ring 43 will drive the welded wiring harness to move out of the semicircular plate 46. At this time, the welded wiring harness can fall out of the semicircular recess of the recessed ring 43. It is worth mentioning that Yes, before the ultrasonic welding equipment body 2 performs welding operation, the telescopic end of the electric push rod 33 will push the U-shaped baffle 32 to move upward, and the U-shaped baffle 32 will form baffles on both sides of the U-shaped platform 31, that is, when the placement platform 3 is performing welding operation, there will be baffles on both sides of the placement platform 3 to limit the wire harness. The wire harness is welded in the above-mentioned semi-automatic manner, which avoids the need for manual adjustment and positioning of the wire harness, resulting in the problem of inconsistent quality of each wire harness welding point, thereby improving the quality of wire harness welding; each time the semicircular notch of the notch ring 43 drives the wire harness to rotate to the inclined position of the trapezoidal pressure plate 48, the wire harness will push the inclined surface of the trapezoidal pressure plate 48 to drive the trapezoidal pressure plate 48 to move upward, and then under the action of the spring force corresponding to the trapezoidal pressure plate 48, the trapezoidal pressure plate 48 will press on the rubber skin part of the wire harness, and proper pressing can help prevent the wire harness from shifting during the welding process to avoid affecting the effect of subsequent welding.

[0024] After the wiring harness is respectively placed in the semicircular recesses of the two recessed rings 43, the wiring harness is also in the semicircular plate 46. The output end of the dual-axis motor 41 will also drive the reciprocating screw rod barrel 51 to rotate during rotation. In the process of the dual-axis motor 41 driving the wiring harness in the recessed ring 43 to rotate to forty-five degrees through the connecting rod 42, the reciprocating screw rod barrel 51 will drive the threaded ring 52 to drive the Z-shaped rod 53 and the arc push rod 54 to move in the direction of the recessed ring 43. The arc push rod 54 will push the rubber skin part of the wiring harness to be flush with the side of the recessed ring 43 during movement, thereby avoiding the problem of the rubber skin part of the wiring harness being located below the welding area of ​​the ultrasonic welding equipment body 2 due to human error during the wiring harness placement process, causing the wiring harness welding failure, which helps to provide a stable position during each wiring harness welding process, thereby reducing the impact of human errors and improving the consistency and reliability of welding. It is worth noting that in the process of the wiring harness in the recessed ring 43 rotating from forty-five degrees to ninety degrees, the reciprocating screw rod barrel 51 The threaded ring 52 will be driven to drive the Z-shaped rod 53 and the arc push rod 54 to reset and move away from the notch ring 43; it should also be noted that in the process of the connecting rod 42 driving the wire harness in the notch ring 43 to rotate to forty-five degrees, the Z-shaped rod 53 will move in the direction of the notch ring 43. At this time, the Z-shaped rod 53 pulls the hinged rod 55 to drive the elastic telescopic plate 57 to move along the inside of the U-shaped track plate 58 toward the placement table 3. The elastic telescopic plate 57 drives the arc pressure plate 59 to move along through the semi-arc plate 56, so that the arc pressure plate 59 pre-forms the overlapping parts of the two wire harnesses to be welded. By pre-forming the overlapping parts of the two wire harnesses to be welded, the arc pressure 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 harness, the setting of the elastic telescopic plate 57 can prevent motion interference between the hinged rod 55 and the Z-shaped rod 53 during operation.

[0025] See also Figure 1 - Fig. 9 On the basis of the above embodiment, in another embodiment of the present invention, a stabilizing device 6 is provided on the inner side of the notch ring 43 .

The arc groove is one centimeter smaller than the upper arc groove, and the lower half arc groove 62 is two centimeters larger than the small arc groove. In the process of the wiring harness in the notch ring 43 rotating from zero degrees to ninety degrees, the above-mentioned structure is set, so that the spring plate 65 is warped and the wiring harness in the semicircular notch of the notch ring 43 is clamped, thereby further improving the stability of the wiring harness in the semicircular notch of the notch ring 43, avoiding the problem of displacement of the wiring harness during the rotation of the notch ring 43. In the process of the wiring harness in the notch ring 43 rotating from one hundred and eighteen degrees to three hundred and sixty degrees (that is, continuing to rotate back to the starting point), the above-mentioned structure is set, so that the slide plate 64 pushes the welded wiring harness in the semicircular notch of the notch ring 43 out of the semicircular notch of the notch ring 43, thereby avoiding the problem of the wiring harness being stuck in the semicircular notch of the notch ring 43 during the discharge process, affecting the operation of the welding processing equipment.

[0027] When in use, during the process of the wiring harness in the notch ring 43 rotating from zero to ninety degrees, the notch ring 43 will drive the slide post 63 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 slide plate 64. At this time, the slide post 63 drives the slide plate 64 to move toward the center of the notch ring 43, and the slide plate 64 drives the spring plate 65 to move along. The edge of the through-opening of the slide plate 64 and the notch ring 43 will squeeze the spring plate 65, and the spring plate 65 will warp and clamp the wiring harness in the semicircular notch of the notch ring 43, thereby further improving the stability of the wiring harness in the semicircular notch of the notch ring 43 and avoiding the notch ring 43 from bringing The problem of displacement of the dynamic wiring harness during rotation is that when the wiring harness in the notch ring 43 rotates from one hundred and eighteen degrees to three hundred and sixty degrees (that is, continues to rotate back to the starting point), the notch ring 43 will drive the slide post 63 from the upper semi-arc groove of the track circular groove 62 to the lower semi-arc groove of the track circular groove 62 through the slide plate 64. At this time, the slide post 63 drives the slide plate 64 to move in the direction away from the center of the notch ring 43.
