Description

[0001] The present application relates to the technical field of ultrasonic welding equipment, in particular to an ultrasonic welding machine. BACKGROUND

[0002] At present, the common straight pressure type ultrasonic metal tab welding machine on the market is basically driven by a pneumatic cylinder. The welding pressure mainly relies on an electric proportional valve, and the pressure is adjusted by adjusting the input air pressure of the pneumatic cylinder.

For some welding applications with high requirements, the pneumatic cylinder type welding machine is prone to virtual welding and overwelding. In addition, the three-link lifting unit generally has a large weight, and when the welding head falls, it is simultaneously affected by gravity, so that the instantaneous speed and impact force of the welding head when contacting the welding seat are large, which affects the welding stability.

[0050] See Figures 1 to 5 An ultrasonic welding machine includes a frame 100, a three-unit lifting module 200, and an electric cylinder 300. The three-unit lifting module 200 is movably connected to the frame 100 and is used to move the welding head. The electric cylinder 300 is located on the top of the frame 100, and its output end is fixedly connected to the three-unit lifting module 200 to drive the three-unit lifting module 200 to move up and down relative to the frame 100.

[0051] This technical solution provides an ultrasonic welding machine. A frame 100 supports components such as a triple-lifting module 200, an electric cylinder 300, and a welding head 250. The triple-lifting module 200 is movably connected to the frame 100, and the welding head is fixedly connected to it, allowing the triple-lifting module 200 to move relative to the frame 100, thereby moving the welding head relative to the frame 100 and achieving welding of the workpiece. The electric cylinder 300, positioned at the top of the frame 100 and fixedly connected to the triple-lifting module 200, drives the module to move up and down relative to the frame 100, thus moving the welding head up and down relative to the frame 100. In this application, the electric cylinder 300 allows for precise adjustment of welding pressure and welding head pressing speed, effectively improving welding quality and stability.

[0052] like Figure 1 and Figure 2 As shown, in one embodiment, the frame 100 includes a frame body 110, which comprises multiple hollow steel sections. These hollow steel sections are joined end-to-end, and the ends of two hollow steel sections are welded together. By configuring the frame body 110 with multiple hollow steel sections joined end-to-end, the overall weight of the frame body 110 is reduced, making it easier to move. Welding the ends of the two joined hollow steel sections only requires ensuring the perpendicularity and flatness of the mounting surfaces of the slide rail 120 and the electric cylinder 300 relative to their respective mounting surfaces on the frame body 110. This reduces the assembly difficulty of the slide rail 120 and the electric cylinder 300, and also reduces the installation difficulty of the frame body 110.

[0053] Specifically, the frame 100 also includes slide rails 120 and sliders 130. Two slide rails 120 are spaced apart on the frame body 110 and extend along the height direction of the frame 100. Sliders 130 correspond one-to-one with slide rails 120 and are located on slide rails 120. The side of slider 130 facing away from slide rail 120 is fixedly connected to the triple lifting module 200.

[0054] By installing slide rails 120 on the frame body 110, and arranging two slide rails 120 at intervals on the frame body 110, a slider 130 slides on the slide rails 120, guiding the slider 130 in conjunction with the slide rails 120. The side of the slider 130 facing away from the guide rail is fixedly connected to the triple-unit lifting module 200, so that the lifting and lowering of the triple-unit lifting module 200 is guided by the guiding cooperation between the slider 130 and the slide rails 120. This arrangement makes the lifting and lowering of the triple-unit lifting module 200 more stable and smooth.

[0055] like Figure 1 and Figure 2As shown, in one embodiment, the frame 100 includes a guide groove 140 extending along the height direction of the frame 100; the triple-unit lifting module 200 includes a connecting plate 210, a guide block 220, a support block 230, and an amplitude transformer 240; the slider 130 is fixedly connected to the connecting plate 210 on the side opposite to the slide rail 120; the guide block 220 is fixedly connected to the side of the connecting plate 210 connected to the slider 130, and the guide block 220 slides within the guide groove 140; the support block 230 is fixedly connected to the side of the connecting plate 210 opposite to the guide block 220; the amplitude transformer 240 passes through a mounting hole on the guide block 220 and engages with the mounting hole; wherein, the opposite end of the welding head 250 is fixedly connected to the amplitude transformer 240, and the other end is fixedly connected to the support block 230.

[0056] The connecting plate 210 is used to connect and support the guide block 220 and the amplitude transformer 240. The slider 130 is fixedly connected to the connecting plate 210 on the side opposite to the slide rail 120, allowing the connecting plate 210 to slide against the frame body 110. The guide block 220 is fixedly connected to the connecting plate 210 and slidably positioned within the guide groove 140 on the frame 100. The guide block 220 and the groove wall of the guide groove 140 provide a guiding fit, resulting in smoother movement of the triple-unit lifting module 200 relative to the frame 100. The support block 230 is fixedly connected to the connecting plate 210 on the side opposite to the guide block 220, supporting one end of the welding head 250.

[0057] Specifically, both the connecting plate 210 and the guide block 220 are block structures, and the support block 230 is constructed as an L-shaped structure. One end of the support block 230 is fixedly connected to the connecting plate 210, and the other end of the support plate is used to connect to and support the welding head 250. The connection between the amplitude rod 240 and the triple-unit lifting module 200 is achieved by matetating the batwing rod with the mounting holes on the guide block 220.

[0058] Furthermore, a mounting groove is provided on the side of the support block 230 opposite to the connecting plate 210. One end of the seat of the welding head 250 is located in the mounting groove, and the seat is fixedly connected to the support block 230 by bolts. The groove wall is used to limit the position of the seat.

[0059] like Figure 1 and Figure 2 As shown, in one embodiment, the ultrasonic welding machine further includes an upper limit assembly 400, which is fixedly connected to the top of the frame 100. When the triple lifting module 200 moves upward along the frame 100 to a preset position, the top of the triple lifting module 200 is stopped and limited by the upper limit assembly 400.

[0060] By setting an upper limit component 400 at the top of the frame 100, the top of the triple lifting module 200 is limited. When the triple lifting module 200 moves upward to the preset position of the frame 100, the upper limit component 400 limits the triple lifting module 200, thereby restricting the triple lifting module 200 from moving upward and protecting the triple lifting module 200, thereby improving the reliability of the ultrasonic welding machine.

[0061] Specifically, the upper limit assembly 400 includes an upper limit seat and a limiting body. The upper limit seat is constructed as an L-shaped plate structure and is fixedly connected to the frame 100. The limiting body is constructed as a cylindrical structure and is fixedly connected to the upper limit seat. One end of the limiting body protrudes from the upper limit seat. When the triple lifting module 200 moves upward to the preset position, the top of the connecting plate 210 of the triple lifting module 200 abuts against the limiting body, thereby restricting the triple lifting module 200 from continuing to move upward.

[0062] like Figure 1 and Figure 2 As shown, in one embodiment, the ultrasonic welding machine further includes a lower limit component 500, which is fixedly connected to the bottom of the frame 100. When the triple lifting module 200 moves down along the frame 100 to a preset position, the bottom of the triple lifting module 200 is stopped and limited by the lower limit component 500.

[0063] By setting a lower limit component 500 at the bottom of the frame 100, when the triple lifting module 200 moves downward to the preset position, the lower limit component 500 stops the triple lifting module 200, thereby restricting the triple lifting module 200 from moving downward and thus protecting the welding head 250 and the workpiece to be welded.

[0064] like Figures 3 to 5 As shown, in one embodiment, the lower limit assembly 500 includes a lower limit seat 510 and a limiting member 520. The lower limit seat 510 is fixedly connected to the frame 100; the limiting member 520 is movably connected to the lower limit seat 510, and the position of the limiting member 520 on the lower limit seat 510 is adjustable so that the height of the limiting member 520 is adjustable.

[0065] By fixing the lower limit seat 510 to the frame 100 and movably connecting the limiting member 520 to the lower limit seat 510, the limiting member 520 stops the triple-unit lifting module 200. The limiting member 520 is configured to have an adjustable position on the lower limit seat 510, allowing for height adjustment. Since the welding head 250 and welding base 800 are prone to wear due to high-frequency vibration during workpiece welding, the height of the limiting member 520 is adjustable so that its height can be adjusted after wear, reliably stopping the triple-unit lifting module 200 and effectively preventing damage to the welding head, welding base 800, and transducer components from dry welding or over-welding.

[0066] like Figures 3 to 5 As shown, in one embodiment, the lower limit assembly 500 further includes a support base 530, an adjusting base 540, and an adjusting rod 550. The limiting member 520 is fixedly connected to the top of the support base 530. A guide groove 531 is formed on one side of the support base 530, and the guide groove 531 is inclined relative to the bottom surface of the support base 530. A guide protrusion 541 is formed on one side of the adjusting base 540, and the guide protrusion 541 is inclined relative to the bottom surface of the adjusting base 540. The support 541 is guided and engaged with the guide groove 531; the adjusting rod 550 is rotatably connected to the adjusting seat 540 and rotatably connected to the lower limit seat 510; wherein, the support seat 530 and the adjusting seat 540 are both located inside the lower limit seat 510, and one end of the adjusting rod 550 protrudes from the lower limit seat 510. When the adjusting rod 550 is rotated, the adjusting rod 550 can drive the adjusting seat 540 to move relative to the lower limit seat 510, so as to drive the support seat 530 to move along the height direction of the lower limit seat 510.

[0067] Specifically, the lower limit seat 510 is constructed as a cuboid shell, and the support seat 530, adjusting seat 540, adjusting rod 550, etc. are all located inside the lower limit seat 510. By fixing the limiting member 520 to the top of the support seat 530, and providing a guide groove 531 on the support seat 530, the guide groove 531 is set in an inclined form relative to the bottom surface of the support seat 530; by providing a wire protrusion on the adjusting seat 540, and setting the guide protrusion 541 inclined relative to the bottom surface of the adjusting seat 540, the guide protrusion 541 guides and cooperates with the guide groove 531. When the driving adjusting seat 540 moves relative to the lower limit seat 510, the guide protrusion 541 drives the support seat 530 to move up and down relative to the lower limit seat 510, thereby adjusting the up and down movement of the limiting member 520 relative to the lower limit seat 510. In this embodiment, the adjusting rod 550 is rotatably connected to the adjusting seat 540 and the lower limit seat 510. The adjusting rod 550 and the adjusting seat 540 are threadedly connected, and the adjusting rod 550 is also rotatably connected to the lower limit seat 510. When the adjusting rod 550 is rotated, it can drive the adjusting seat 540 to move along the axial direction of the adjusting rod 550. In this embodiment, the axial direction of the adjusting rod 550 is horizontal. When the adjusting seat 540 moves horizontally, the guide protrusion 541 on the adjusting seat 540 can drive the support seat 530 to move up and down along the lower limit seat 510. This configuration converts the rotational motion of the adjusting rod 550 into the linear movement of the adjusting seat 540. The horizontal movement of the adjusting seat 540 is converted into the vertical movement of the support seat 530 through the cooperation of the inclined guide protrusion 541 and the guide groove 531. The structure is simple and compact, and the transmission is stable and reliable.

[0068] like Figure 1 and Figure 2 As shown, in one embodiment, the ultrasonic welding machine further includes a pressure detection element 600, which is disposed on the triple-lift module 200 to detect the pressure of the welding head 250. The ultrasonic welding machine also includes a position detection element 700, which is disposed on the frame 100 and is used to detect the position of the workpiece.

[0069] Specifically, the pressure detection component 600 is an S-type pressure sensor, and the position detection component 700 is a precision magnetic scale. By setting the pressure sensor on the triple-unit lifting module 200, the welding pressure can be detected directly and effectively, thereby allowing for precise fine-tuning of the welding pressure in conjunction with the electric cylinder 300. Setting the precision magnetic scale on the frame 100 can effectively detect the pre-welding thickness height and difference, and promptly alarm for welding defects such as incomplete welding, over-welding, or abnormal incoming material quality.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
