Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding machine technology, specifically an ultrasonic wire harness welding machine. Background Technology

[0002] Ultrasonic waves can generate high-frequency vibrations, which can be used to easily weld non-ferrous metals. Ultrasonic wire harness welding machines are derivative equipment of ultrasonic metal welding machines. They are mainly used for welding copper and aluminum wires in automotive wire harnesses, motorcycle wire harnesses, etc., so they are often called automotive wire harness welding machines. Traditional ultrasonic wire harness welding machines have some disadvantages. First, the wire harness is not very firmly fixed and it is not easy to clamp the wire harness tightly.

[0003] An existing patent application (application number 202122939311.2) describes a rapid-positioning ultrasonic wire harness welding machine, belonging to the field of ultrasonic welding technology. It addresses the problem that existing welding machines often cause wire harnesses to wobble left and right after being impacted by the welding head, affecting welding results. The machine includes a substrate with four threaded holes on its surface and an L-shaped support plate fixedly connected to the rear end of its upper surface. An electric cylinder is also included, fixedly mounted on the upper end of the L-shaped support plate, with its drive shaft passing through the L-shaped support plate and fixedly connected to the welding head. This invention utilizes a bolted connection between the fixing block and the substrate, making installation and removal of the fixing block easier for workers. Furthermore, the use of limiting posts between the substrate and the fixing block ensures that the threaded holes at both ends of the fixing block align with the threaded holes on the substrate surface, allowing workers to quickly fix the fixing block to the upper end of the substrate. However, the single method of clamping and fixing the two wire harnesses limits the welding efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic wire harness welding machine to solve the problem that the existing technology uses a single method for clamping and fixing two wire harnesses, which affects the efficiency of wire harness welding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic wire harness welding machine, comprising a lower base, wherein two transverse sliding blocks are provided in the upper part of the lower base via a lead screw threaded towards each other, and an ultrasonic welding head is provided at the upper end of each of the two transverse sliding blocks via a vertical frame; a fixed clamp and an upper support are also provided on the upper wall of the lower base; a first movable clamp is provided in the top of the upper support via a first cylinder; a first wire clamping groove is provided on one side of both the fixed clamp and the first movable clamp; a second movable clamp is provided on one side of the first movable clamp via a second cylinder; and a second wire clamping groove is provided between the first movable clamp and the second movable clamp.

[0006] Furthermore, the upper support is an inverted U-shaped support, and two sets of the upper support are arranged in parallel.

[0007] Furthermore, the inner wall of the upper support is provided with a limiting slide rail, and the two sides of the first movable clamp are provided with limiting slide grooves that slide with the limiting slide rail.

[0008] Furthermore, the lead screw includes a lead screw rotatably disposed in a transverse slide groove on the upper side of the lower machine base, and two opposite external threads are provided on the outer sides of both ends of the lead screw, and a servo motor is drivenly connected to one end of the lead screw.

[0009] Furthermore, both the first and second wire clamping grooves are arc-shaped grooves, and the inner walls of the first and second wire clamping grooves are also provided with a protective layer.

[0010] Furthermore, the second cylinder is vertically mounted on the outer wall of the movable clamp via an outer bracket, and the two side walls of the second movable clamp are slidably mounted on the inner wall of the outer bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model has a first wire clamping groove on one side of both the fixed clamp and the first movable clamp for horizontally clamping and fixing a wire bundle. A second wire clamping groove is also provided between the first and second movable clamps to vertically clamp and fix the end of another wire bundle, thereby achieving vertical positioning of the two wire bundles to be welded. Moreover, the positioning stability is high, which is beneficial to improving the accuracy of vertical welding of the wire bundles. At the same time, the first wire clamping groove can be used to coaxially and horizontally clamp and fix one end of the two wire bundles, improving the flexibility of the clamping and fixing method of the two wire bundles.

[0013] 2. The present invention features arc-shaped grooves for both the first and second wire clamping grooves, and a protective layer with a rubber structure on the inner wall of the first and second wire clamping grooves. This increases the contact area and anti-slip properties between the wire clamping grooves and the wire harness, thereby improving the stability of the wire harness being clamped and fixed in the wire clamping grooves.

[0014] 3. In this utility model, two transverse sliding blocks are provided in the upper part of the lower base through a screw thread facing each other, and ultrasonic welding heads are provided at the upper end of each transverse sliding block through a vertical frame. This allows the two transverse sliding blocks to be moved and adjusted in opposite directions by driving the screw, and the two ultrasonic welding heads can be moved and adjusted synchronously in opposite directions. This enables simultaneous welding of both sides of the two wire harnesses after positioning, thus improving the efficiency of wire harness welding. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the invention, an ultrasonic wire harness welding machine includes a lower base 1. Two transverse sliding blocks 3 are threaded in opposite directions on the upper part of the lower base 1 via a lead screw. Ultrasonic welding heads 5 are mounted on the upper ends of both transverse sliding blocks 3 via a support frame 4.

This allows for synchronous movement and adjustment of the two ultrasonic welding heads 5, thereby enabling simultaneous welding of both sides of the positioned wire harnesses and improving the efficiency of wire harness welding.

[0022] like Figure 1 and Figure 3As shown, in order to clamp and fix the two wire harnesses in different directions, a fixed clamping seat 7 and an upper bracket 10 are also provided on the upper wall of the lower base 1. The top of the upper bracket 10 is provided with a first movable clamping seat 8 through a first cylinder 11. Both the fixed clamping seat 7 and the first movable clamping seat 8 are provided with a first wire clamping groove 9 on one side for horizontal clamping and fixing of one wire harness. A second movable clamping seat 12 is also provided on one side of the first movable clamping seat 8 through a second cylinder 14. The second cylinder 14 is vertically set on the outer wall of the first movable clamping seat 8 through an outer bracket 13. The two side walls of the second movable clamping seat 12 are slidably set with the inner wall of the outer bracket 13. A second wire clamping groove 15 is also provided between the first movable clamping seat 8 and the second movable clamping seat 12, which can vertically clamp and fix the end of the other wire harness, thereby realizing the vertical positioning of the two wire harnesses to be welded. Moreover, the positioning stability is high, which is beneficial to improving the accuracy of vertical welding of the wire harnesses. Furthermore, the first wire clamping groove 9 can be used to coaxially clamp and fix one end of the two wire harnesses.

[0023] like Figure 1 and Figure 2 As shown, in order to improve the stability of the lifting and lowering adjustment of the first movable clamp 8, the upper support 10 is an inverted U-shaped support, and two sets of upper support 10 are arranged in parallel. The inner wall of the upper support 10 is provided with a limiting slide rail 16, and the two sides of the first movable clamp 8 are provided with limiting slide grooves 17 that slide with the limiting slide rail 16. These grooves are used to guide the first movable clamp 8 during lifting and lowering adjustment, which helps to improve the stability of the lifting and lowering adjustment of the first movable clamp 8.

[0024] like Figure 2 and Figure 3 As shown, in order to improve the stability of the wire harness clamped and fixed in the clamping groove, both the first clamping groove 9 and the second clamping groove 15 are arc-shaped grooves, and the inner walls of the first clamping groove 9 and the second clamping groove 15 are also provided with protective layers, which increases the contact area and anti-slip properties between the clamping groove and the wire harness, and facilitates the improvement of the stability of the wire harness clamped and fixed in the clamping groove.

[0025] The working principle and usage process of this utility model are as follows: When in use, the wire bundle to be welded is placed horizontally in the wire clamping groove on the upper side of the fixed clamp 7, and the welding part with the outer sheath removed is located in the middle of the fixed clamp 7. Then, the first movable clamp 8 is driven to move down by the first cylinder 11 to clamp and fix it horizontally. Then, another wire bundle is inserted into the second wire clamping groove 15 for clamping and fixing. The two positioned wire bundles are welded on both sides simultaneously by two ultrasonic welding heads 5, which improves the efficiency of wire bundle welding.
