Description

Technical Field

[0001] The utility model relates to the field of welding machines, in particular to an ultrasonic metal welding machine for wire welding processing. Background Art

[0002] Ultrasonic metal welders, also known as ultrasonic gold welders, use high-frequency vibration waves to weld metals. However, current equipment like these does face some technical challenges when processing soft materials like wires.

[0003] Specifically, because the fixture design may not fully consider the conductor's flexibility and potential deformation during welding, the wire can easily slip or shift within the fixture during welding, making it difficult to precisely align the weld tip. Setting the clamping force is also a major challenge: insufficient clamping force cannot ensure the conductor's stability during welding, while excessive clamping force may damage the wire and affect its conductivity.

[0004] In addition, the high-frequency vibrations generated by the welding head during ultrasonic welding may be transmitted to the fixture and wire, causing slight displacement of the wire in the fixture, thereby affecting the accuracy of welding.

[0005] Another factor that cannot be ignored is the skill level of the operator. If the operator cannot correctly set the fixture, adjust the clamping force or control the welding parameters, it may also cause the weld end to deviate and affect the weld quality. Utility Model Content

[0006] The main purpose of the utility model is to provide an ultrasonic metal welding machine for wire welding processing, which can effectively solve the problems raised in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] An ultrasonic metal welding machine for wire welding processing includes a base, a column, a height adjustment device, a welding head, a wire harness and a workbench. The upper and lower ends of the column are respectively provided with a height adjustment device and a base. The welding head is mounted on the adjustment end of the height adjustment device, and the workbench is mounted on the base.

[0009] The upper end of the workbench is provided with a plurality of jacks, two insertion tubes are installed in two jacks in the same row, and a limiting cylinder is installed on each of the insertion tubes, and the wiring harness passes through the two limiting cylinders to achieve limited winding;

[0010] A mounting tube is installed in the socket facing the welding head, and a clamping platform is installed on the mounting tube, two fixed clamping tubes are installed on the upper end of the clamping platform, and a notch facing the fixed clamping tube is opened on the clamping platform, a movable clamping tube is embedded in each of the notches, and the outer ends of the two movable clamping tubes are connected with connecting strips, a mounting frame is provided at the outer end of the clamping platform, and a fine-tuning screw connected to the connecting strip is installed on the mounting frame, and the fine-tuning screw is rotated to adjust the position of the movable clamping tube in the notch, and the two wiring harnesses pass through the fixed clamping tube and the movable clamping tube and the movable clamping tube is adjusted by the fine-tuning screw to clamp the wiring harness, which is beneficial to the welding of the wiring harness by the welding head.

[0011] Wherein, the insertion tube and the mounting tube are both screw tubes, which are inserted into the jack and sleeved with nuts and anti-slip washers. The insertion tube and the mounting tube are fixed on the workbench, and the height of the mounting tube and the insertion tube are adjusted to be parallel, and the mounting tube and the insertion tube are located on the same line;

[0012] The clamping platform is designed as an integral unit with the mounting tube, and the lower end of the fixed clamping tube is a threaded portion, through which the fixed clamping tube is connected to the clamping platform.

[0013] Wherein, the surfaces of the movable clamping tube and the fixed clamping tube are provided with anti-slip rubber sleeves, and the wiring harness contacts the anti-slip rubber sleeves;

[0014] The two movable clamping tubes are located at both ends of the connecting bar, the cross section of the mounting frame is designed in a "U" shape, and the mounting frame is fixed to the clamping platform by bolts;

[0015] Wherein, the end of the fine-tuning screw is provided with a limiting ring, which is sleeved in the annular groove of the end of the fine-tuning screw and is fixed to the connecting bar through the limiting ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this utility model, the conductor can be precisely clamped between the fixed clamping tube and the movable clamping tube on the clamping table. The movable clamping tube is precisely adjusted by a fine-tuning screw to ensure that the conductor does not move or shake during the welding process, thereby greatly improving the stability of the welding.

[0018] The winding mechanism, with its insertion tube and stopper, ensures neat and orderly wire winding, reducing welding errors caused by uneven winding. Furthermore, precise alignment of the clamping mechanism with the welding head ensures accurate weld placement. The integrated design of the clamping platform and mounting tube, coupled with the active clamping tube's connection to the clamping platform via a connecting strip, makes installation and adjustment of the clamping mechanism simple and quick. Operators simply turn the fine-tuning screw to securely clamp the wire, significantly improving work efficiency.

[0019] The clamping and winding mechanisms are designed with safety in mind. The non-slip rubber sleeve ensures stable contact between the wire and the clamping mechanism, while also preventing scratches on the wire during welding. Furthermore, the retaining ring on the fine-tuning screw ensures stability during adjustment, preventing accidents caused by improper operation. Because the wire maintains a stable and precise position during welding, the welding head accurately transmits ultrasonic vibrations to the contact surface of the wire, resulting in a high-quality weld. This not only improves the strength and reliability of the weld, but also extends the life of the wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 - Figure 4 As shown in the figure, we have meticulously designed an efficient and stable ultrasonic metal welding machine specifically for wire welding. The core components of this machine include a base 1, a column 2, a height adjustment device 3, a welding head 4, a wire harness 7, and a workbench 5. Column 2 serves as the primary support structure for the entire machine, with its upper and lower ends tightly connected to the height adjustment device 3 and base 1, respectively, ensuring the stability of the machine.

[0027] The welding head 4, a key component of the welding operation, is mounted on the adjustable end of the height adjustment device 3. It can adjust the welding height according to actual needs to achieve precise welding. The workbench 5 is firmly mounted on the base 1, providing a stable working platform for welding operations.

[0028] The top of the workbench 5 is cleverly designed with multiple insertion holes 6. Within these insertion holes 6, two insertion tubes 8 are installed for every two insertion holes 6 in the same row. Each insertion tube 8 is further mounted with a stopper 9. This allows the wire harness 7 to easily pass through these two stopper tubes 9, achieving a controlled winding and ensuring stability during the welding process.

[0029] A mounting tube 11 is specially designed for the socket 6 facing the welding head 4, onto which the clamping platform 10 is mounted. The upper end of the clamping platform 10 is equipped with two fixed clamping tubes 12, with a notch 13 facing each other between the two fixed clamping tubes 12. A movable clamping tube 14 is embedded in each notch 13. The outer ends of the two movable clamping tubes 14 are connected by a connecting bar 15, while the outer end of the clamping platform 10 is equipped with a mounting bracket 16, on which is mounted a fine-tuning screw 17 that is restricted by the connecting bar 15. By turning the fine-tuning screw 17, the position of the movable clamping tube 14 in the notch 13 can be precisely adjusted, ensuring that the two wire harnesses 7 can pass through the fixed clamping tubes 12 and the movable clamping tube 14. The fine-tuning screw 17 is used to adjust the movable clamping tube 14 so that it firmly clamps the wire harness 7, providing optimal conditions for welding operations at the welding head 4.

[0030] Both the insertion tube 8 and the mounting tube 11 are designed as screw-type tubes, allowing them to be easily inserted into the socket 6 and securely fixed to the workbench 5 via the provided nuts and non-slip washers. During installation, the height of the mounting tube 11 and the insertion tube 8 are properly adjusted to maintain parallelism and alignment, ensuring accurate welding.

[0031] The clamping platform 10 and mounting tube 11 are integrated into a single piece, ensuring structural stability and easy operation. The fixed clamping tube 12 has a threaded lower end, allowing it to be easily connected to the clamping platform 10. Both the movable clamping tube 14 and the fixed clamping tube 12 are covered with non-slip rubber sleeves, which not only ensure stable contact between them and the wiring harness 7 but also provide some protection from scratches.

[0032] Two movable clamping tubes 14 are located at either end of the connecting bar 15, while the mounting bracket 16 has a U-shaped cross-section, allowing it to be securely bolted to the clamping platform 10. A retaining ring is also provided at the end of the fine-tuning screw 17. This retaining ring fits within an annular groove at the end of the fine-tuning screw 17, ensuring that the fine-tuning screw 17 is stably fixed to the connecting bar 15, enabling fine-tuning.

[0033] The design of the entire equipment fully considers the convenience, stability and safety of operation, ensuring that the welding task can be completed efficiently and stably during the wire welding process.

[0034] Working process: Pass the wire harness 7 through the limiting cylinder 9 on the insertion tube 8 to achieve initial positioning. Insert the mounting tube 11 into the socket 6 of the welding joint 4 and secure it firmly. Install the clamping platform 10 and the mounting tube 11 as a whole to ensure structural stability.

[0035] The wiring harness 7 is passed through the fixed clamping tube 12 on the clamping platform 10 so that the wiring harness 7 is located between the fixed clamping tube 12 and the movable clamping tube 14. The movable clamping tube 14 is connected to the clamping platform 10 through the connecting strip 15 to ensure that the movable clamping tube 14 can move in the gap 13.

[0036] By turning the fine-tuning screw 17, the two movable clamping tubes 14 are driven to move toward the center through the connecting bar 15 until the wire harness 7 is firmly clamped. By accurately adjusting the fine-tuning screw 17, the wire harness 7 is ensured to remain stable during the welding process.

[0037] During welding: adjust the height adjustment device 3 so that the welding head 4 is aligned with the clamped wire harness 7. Ensure that the contact surface between the welding head 4 and the wire harness 7 is clean and free of impurities to ensure welding quality.

[0038] The ultrasonic metal welding machine is started, and the welding head 4 begins to emit ultrasonic vibrations. The ultrasonic vibrations are transmitted to the contact surface of the wire harness 7 through the welding head 4, causing the metal atoms on the contact surface to undergo plastic deformation under high temperature and high pressure, thereby achieving fusion between the metals.

[0039] When the welding head 4 stops vibrating, welding is complete. The ultrasonic metal welder is turned off, and subsequent operations can be performed after the weld has cooled and solidified. Throughout the welding process, the wire harness 7 is securely clamped to the clamping table 10, ensuring stability and accuracy, thereby improving weld quality.
