Description

Technical Field

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

[0002] Ultrasonic metal welding is a special method that uses the mechanical vibration energy of ultrasonic frequencies to join similar or dissimilar metals. This method does not supply current or apply high-temperature heat to the workpiece during welding; instead, it converts mechanical energy into internal energy, deformation energy, and a limited temperature rise through static pressure, causing solid-state welding of the two base materials at the recrystallization temperature. Its applications are very wide, especially in the processing of CCS integrated busbars for energy storage.

[0003] Since the power required for ultrasonic welding of metal increases exponentially with the increase of workpiece thickness and hardness, it is mostly only suitable for welding thin parts such as wires, foils, sheets, strips and bands. In order to ensure the success of welding, the thin metal parts need to be positioned to prevent the welding surface from shifting due to the movement of the thin metal parts during welding, which would affect the welding effect. Therefore, further improvements can be made. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: an ultrasonic metal welding device, comprising a base, a bracket fixedly installed in the center of the back of the base, a housing fixedly installed on the top of the bracket, an ultrasonic generator disposed on the bottom side of the housing, a welding head disposed on the bottom of the ultrasonic generator, a processing table disposed on the top side of the base and directly below the welding head, a sliding groove being formed inside the base and on both sides of the processing table, and a movable positioning component disposed inside the sliding groove of the base.

[0005] As an optimization, the moving positioning component includes a drive assembly for transmission fixedly installed inside the base, and a positioning assembly for clamping metal workpieces is provided inside the slide groove. The drive assembly drives the positioning assembly so that the positioning assembly can slide back and forth along the slide groove to adjust its position.

[0006] As an optimization, the drive assembly includes a mounting base fixedly installed inside the base, and a dual-axis motor is fixedly installed inside the mounting base. Both output shafts of the dual-axis motor are fixedly mounted with screws.

[0007] As an optimization, the positioning component includes a stand that is slidably connected inside the slide groove. A connecting plate is fixedly installed at the bottom of the dual-axis motor. A threaded hole is opened in the middle of the connecting plate, and the screw is screwed into the threaded hole in the middle of the connecting plate. By starting the dual-axis motor, the screws on both sides will rotate in the threaded hole, which will in turn drive the stand to slide closer or further away from each other along the inner wall of the slide groove.

[0008] As an optimization, an electric push rod is fixedly installed on the top of the stand, and a pressure plate is fixedly installed on the telescopic end of the electric push rod. The pressure plate is slidably connected inside the stand. An upper fixing plate is fixedly installed inside the stand and above the top side of the base. By activating the electric push rod, the pressure plate will slide downward and press against the top side of the upper fixing plate.

[0009] As an optimization, a limiting groove is provided on the inner side of the upright frame, and the two sides of the pressure plate have protruding edges, which are slidably connected in the limiting groove. The sliding of the protruding edges in the limiting groove further limits and guides the pressure plate, allowing it to slide vertically. The pressure plate and the upper fixed plate are provided with serrated pads on opposite sides. The serrated pads will further improve the positioning effect on the metal workpiece when the pressure plate presses down on the top side of the upper fixed plate.

[0010] As an optimization, a lower fixing plate is fixedly installed inside the frame and below the upper fixing plate. Ball bearings are embedded on the opposite sides of the upper and lower fixing plates. Slide tracks are provided on the upper and lower sides of the base facing the upper and lower fixing plates. The ball bearings are connected to the slide tracks in a rolling manner. By rolling the ball bearings along the slide tracks, friction can be reduced.

[0011] The beneficial effects of this utility model are:

[0012] 1. This ultrasonic metal welding device, by activating the electric push rod, will cause the pressure plate to slide downward, thus clamping and positioning the metal sheet. Then, by activating the dual-axis motor, the screw will rotate. The dual-axis motor rotates in the threaded hole inside the screw, thus causing the two uprights to slide closer to each other along the inner wall of the slide groove, thereby facilitating the adjustment of the spacing position as needed.

[0013] 2. This ultrasonic metal welding device can play a limiting and guiding role by sliding the convex edges on both sides of the pressure plate along the limiting groove, ensuring that the pressure plate slides vertically. Furthermore, the serrated pad makes the pressure plate more stable when clamping the metal sheet downward, which further improves the positioning effect of the metal workpiece and avoids accidental movement that could cause the welding surface to shift, thus avoiding affecting the welding effect.

[0020] The technical solutions of the present utility model 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 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 An ultrasonic metal welding device includes a base 1, a bracket 2 fixedly installed on the back center of the base 1, a housing 3 fixedly installed on the top of the bracket 2, an ultrasonic generator 4 provided on the bottom side of the housing 3, a welding head 5 installed on the bottom of the ultrasonic generator 4, a processing table 6 provided on the top side of the base 1 and directly below the welding head 5, a sliding groove 7 provided inside the base 1 and on both sides of the processing table 6, and a movable positioning component 8 provided inside the sliding groove 7 of the base 1.

[0022] Please see Figure 2 The movable positioning component 8 includes a drive assembly for transmission that is fixedly installed inside the base 1. The slide groove 7 is provided with a positioning assembly for clamping metal workpieces, and the drive assembly transmits the positioning assembly so that the positioning assembly can slide back and forth along the slide groove 7 to adjust its position.

[0023] Please see Figure 2 The drive assembly includes a mounting base 9 fixedly installed inside the base 1. A dual-axis motor 10 is fixedly installed inside the mounting base 9. Screws 11 are fixedly installed on both ends of the output shaft of the dual-axis motor 10.

[0024] Please see Figure 3-4 The positioning component includes a stand 12 that is slidably connected inside the slide 7. A connecting plate 13 is fixedly installed at the bottom of the dual-axis motor 10. A threaded hole is opened in the middle of the connecting plate 13, and a screw 11 is screwed into the threaded hole in the middle of the connecting plate 13. By starting the dual-axis motor 10, the screws 11 on both sides will rotate in the threaded hole, which will in turn drive the stand 12 to slide relative to each other along the inner wall of the slide 7, moving closer or further away.

[0025] Please see Figure 3-4 An electric push rod 14 is fixedly installed on the top of the upright frame 12. A pressure plate 15 is fixedly installed on the telescopic end of the electric push rod 14, and the pressure plate 15 is slidably connected inside the upright frame 12. An upper fixed plate 16 is fixedly installed inside the upright frame 12 and above the top side of the base 1. By starting the electric push rod 14, the pressure plate 15 will slide downward and press against the top side of the upper fixed plate 16, thereby clamping and positioning the metal workpiece.

[0026] Please see Figure 3-4 The inner side of the upright 12 is provided with a limiting groove 17. The two sides of the pressure plate 15 have protruding edges, and the protruding edges are slidably connected in the limiting groove 17. By sliding the protruding edges in the limiting groove 17, the pressure plate 15 is further limited and guided, so that it can slide vertically. The pressure plate 15 and the upper fixed plate 16 are provided with serrated pads 18 on opposite sides. The serrated pads 18 will make the pressure plate 15 press down on the top side of the upper fixed plate 16, further improving the positioning effect of the metal workpiece and avoiding accidental movement that would cause the welding surface to shift.

[0027] Please see Figure 3-4 Inside the upright frame 12 and below the upper fixed plate 16, a lower fixed plate 19 is fixedly installed. The upper fixed plate 16 and the lower fixed plate 19 are both fitted with ball bearings 20. The base 1 has slides on the upper and lower sides of the upper fixed plate 16 and the lower fixed plate 19. The ball bearings 20 are rolled in the slides. By rolling along the slides, the friction can be reduced, making it easy for the upright frame 12 to slide back and forth to adjust its position.

[0028] In use, first place the metal sheet to be welded on the upper fixed plate 16, then start the electric push rod 14 to drive the pressure plate 15 to slide down, thereby clamping and positioning the metal sheet. Then start the dual-axis motor 10 to drive the screw 11 to rotate. The dual-axis motor 10 rotates in the threaded hole in the screw 11, so it will drive the two uprights 12 to slide closer to each other along the inner wall of the slide groove 7, thereby facilitating the adjustment of the spacing position.

[0029] At the same time, the sliding of the protruding edges on both sides of the pressure plate 15 along the limiting groove 17 can play a limiting and guiding role, ensuring that the pressure plate 15 slides vertically. Furthermore, the serrated pad 18 makes the pressure plate 15 more stable when clamping the metal sheet downward, further improving the positioning effect on the metal workpiece.

[0030] In summary, this ultrasonic metal welding device, by activating the electric push rod 14, causes the pressure plate 15 to slide downward, thus clamping and positioning the metal sheet. Then, by activating the dual-axis motor 10, the screw 11 is rotated. Since the dual-axis motor 10 rotates in the threaded hole inside the screw 11, it causes the two uprights 12 to slide closer to each other along the inner wall of the slide groove 7, thereby facilitating the adjustment of the spacing position as needed.

[0031] The sliding of the protruding edges on both sides of the pressure plate 15 along the limiting groove 17 can play a limiting and guiding role, ensuring that the pressure plate 15 slides vertically. Furthermore, the serrated pad 18 makes the pressure plate 15 more stable when clamping the metal sheet downward, further improving the positioning effect of the metal workpiece. This can prevent accidental movement that could cause the welding surface to shift and thus avoid affecting the welding effect.
