Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a stop module and an ultrasonic welding device. Background Technology

[0002] Ultrasonic welding utilizes high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects rub against each other, forming a fusion between molecular layers.

[0003] When welding wire harnesses to terminals, one end of the wire harness needs to be positioned onto the terminal before welding. In existing ultrasonic metal wire harness welding equipment, the gap between the welding head and the wire harness stop needs to be adjusted to 0.03-0.05mm on each side to ensure that the wire harness does not slip during welding. However, the stop mechanism in existing ultrasonic welding equipment is relatively simple, and the position of the stop cannot be finely adjusted, which is very inconvenient.

[0004] Therefore, a stop module and ultrasonic welding equipment are needed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An ultrasonic welding device includes: a carrier and two stop mechanisms disposed on the carrier, each stop mechanism including a slide, a stop, an adjustment component and a locking component; The slide block is slidably disposed on the carrier, the sliding direction of the slide block is horizontal, the two slide blocks are disposed opposite each other in the horizontal direction, the two stops are disposed on the side of the two slide blocks that are close to each other, and there is a welding space between the two stops; The adjusting component is used to drive the slide closer to or away from the welding space, and the locking component is used to lock the slide onto the carrier.

[0007] The carrier is provided with a sliding hole, and the slide block is slidably disposed in the sliding hole.

[0008] The adjustment assembly includes an elastic element, a mounting plate, and a micrometer head. The mounting plate is disposed on the carrier, and the micrometer head is disposed on the mounting plate. The micrometer head is horizontally positioned and located on the side of the slide away from the welding space. The measuring head of the micrometer head abuts against the slide. The elastic element is disposed between the slide and the carrier, and the elastic element is used to apply a thrust to the slide toward the side away from the welding space.

[0009] The locking assembly includes a locking plate and a plurality of locking bolts. The locking plate is disposed on one side of the slide. The carrier is provided with a plurality of oblong holes. The length direction of the oblong holes is consistent with the sliding direction of the slide. The plurality of locking bolts are respectively inserted into the plurality of oblong holes and are threadedly connected to the locking plate.

[0010] A pad is provided on the side of each of the two stops that are close to each other.

[0011] The elastic element is a spring.

[0012] The two slides are provided with grooves on their adjacent sides, and the elastic element is disposed in the grooves.

[0013] An ultrasonic welding device includes the aforementioned stop module; It also includes a base and an ultrasonic welding head, the base being positioned directly below the welding space, and the ultrasonic welding head being used to weld workpieces within the welding space.

[0014] It also includes two slide rails and a drive cylinder. The two sides of the carrier are slidably mounted on the two slide rails. The drive cylinder is used to drive the carrier to slide on the slide rails. The slide rails extend in the vertical direction.

[0015] It also includes two buffers, which are respectively disposed on the two slide rails. Buffer plates are disposed on both sides of the carrier, and the two buffer plates are respectively disposed directly above the two buffers.

[0016] The above-described structure of this utility model can achieve the following beneficial effects: During use, the terminals and wire harnesses to be welded are placed in the welding space. The ultrasonic welding head continues to weld the terminals and wire harnesses in the welding space from top to bottom, while two stops limit the movement from both sides. When the gap between the stops and the ultrasonic welding head is too large, the sliding block is driven to move closer to one side of the welding space by adjusting the component, so that the gap meets the requirements of the welding process. This prevents the wire harness from slipping when welding the terminal, thereby ensuring the quality of the welding and improving the yield. Attached Figure Description

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0022] Example 1, Reference Figures 1-2 An ultrasonic welding device is shown, including: a carrier 1 and two stop mechanisms 2 disposed on the carrier 1. The stop mechanism 2 includes a slide 21, a stop 22, an adjustment component and a locking component. The slide block 21 is slidably disposed on the carrier 1. Specifically, the slide block 21 can be slidably disposed in the slide hole 11 provided on the carrier 1. The sliding direction of the slide block 21 is horizontal. The two slide blocks 21 are arranged opposite each other in the horizontal direction. The two stops 22 are arranged on the side of the two slide blocks 21 that are close to each other. The space between the two stops 22 is the welding space. The adjusting component is used to drive the slide 21 closer to or further away from the welding space, and the locking component is used to lock the slide 21 onto the carrier 1.

[0023] Based on the above structure, during use, the terminals and wire harnesses to be welded are placed in the welding space, and the ultrasonic welding head 4 continues to weld the terminals and wire harnesses in the welding space from top to bottom. The two stops 22 limit the distance from both sides. When the gap between the stops 22 and the ultrasonic welding head 4 is too large, the sliding block 21 is driven to move closer to one side of the welding space by adjusting the component, so that the gap meets the requirements of the welding process, and the wire harnesses and terminals are prevented from slipping during welding, thereby ensuring the quality of welding and improving the yield.

[0024] like Figures 2-4 As shown, the adjustment assembly includes an elastic element 23, a mounting plate 24, and a micrometer head 25. The mounting plate 24 is mounted on the carrier 1, and the micrometer head 25 is mounted on the mounting plate 24. The micrometer head 25 is horizontally positioned on the side of the slide 21 away from the welding space, and the measuring head of the micrometer head 25 abuts against the slide 21. The elastic element 23 is positioned between the slide 21 and the carrier 1. The elastic element 23 applies a pushing force to the slide 21 towards the side away from the welding space. Thus, by rotating the micrometer head 25, the extension of the measuring head of the micrometer head 25 is adjusted. In conjunction with the elastic force of the elastic element 23, the extension of the measuring head increases, causing the slide 21 to move towards the welding space. The elastic force of the elastic element 23 keeps the slide 21 in close contact with the measuring head, thereby adjusting the position of the slide 21 and ensuring the distance between the stop block 22 and the ultrasonic welding head 4.

[0025] like Figures 2-4 As shown, the locking assembly includes a locking plate 26 and several locking bolts 27. The locking plate 26 is disposed on one side of the slide 21. The carrier 1 is provided with several oblong holes 12. The length direction of the oblong holes 12 is consistent with the sliding direction of the slide 21. Several locking bolts 27 are respectively inserted into several oblong holes 12 and are threadedly connected to the locking plate 26. Thus, after the position of the slide 21 is adjusted (during the adjustment of the slide 21, the locking bolts 27 are locked and slide within the oblong holes 12), the locking plate 26 is fixed by tightening the locking bolts 27, thereby fixing the position of the slide 21.

[0026] A further optimization is that pads 28 are provided on the sides of the two stops 22 that are close to each other, thereby providing better support for both sides of the terminal.

[0027] A further optimization is that the elastic element 23 can be a spring or a sheet, and grooves are provided on the side of the two slides 21 that are close to each other. The elastic element 23 is placed in the groove, thus completing the installation of the elastic element 23.

[0028] In addition to Embodiment 1, this application also discloses Embodiment 2, an ultrasonic welding device including the stop module described in Embodiment 1; It also includes a base 3 and an ultrasonic welding head 4. The base 3 is positioned directly below the welding space, and the ultrasonic welding head 4 is used to weld the workpiece within the welding space. In use, the ultrasonic welding head 4, the two stops 22, and the base 3 are placed around the terminals and wire harnesses respectively to restrict their positions, and the terminals and wire harnesses are welded using the ultrasonic welding head 4. like Figure 1 and Figure 3 As shown, this embodiment also includes two slide rails 5 and a drive cylinder 6. The two sides of the carrier 1 are slidably mounted on the two slide rails 5. The drive cylinder 6 is used to drive the carrier 1 to slide on the slide rails 5. The slide rails 5 extend in the vertical direction. By driving the carrier 1 to slide through the drive cylinder 6, the height of the two stops 22 is adjusted to ensure that a suitable height difference is maintained between the two stops and the base.

[0029] Further optimizations include, for example Figure 1 and Figure 3 As shown, this embodiment also includes two buffers 7 (hydraulic buffers can be selected). The two buffers 7 are respectively set on two slide rails 5. Buffer plates 13 are provided on both sides of the carrier 1. The two buffer plates 13 are respectively set directly above the two buffers 7. The position of the carrier 1 is restricted by the two buffers 7, so that the two stops 22 are stopped at a suitable height. The flexibility of this application can be further improved by adjusting the limiting height of the two buffers 7.

[0030] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
