DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] The utility model provides a desktop ultrasonic metal welding machine to solve the problem that the ultrasonic metal welding machine in the prior art occupies a large area, is inconvenient to be placed on a table for work, and also needs to adjust the clamping block to clamp the width of the terminal, which is inconvenient to operate.

[0029] For ease of understanding, the specific process in the embodiments of the present application is described below. Figures 1 to 3 A desktop ultrasonic metal welding machine in an embodiment of the present application includes a bearing table 1, a fixing seat 2, an ultrasonic welding module 3, a welding bottom die 4, a wire harness clamping assembly 5 and a terminal clamping assembly 6: the fixing seat 2 is arranged on the bearing table 1; the ultrasonic welding module 3 is arranged on the fixing seat 2 in a liftable manner; the welding bottom die 4 and the wire harness clamping assembly 5 are arranged on the bearing table 1 relatively to each other, and are located on one side of the welding end of the ultrasonic welding module 3, and are respectively used to place the terminal and clamp the wire harness; the terminal clamping assembly 6 is arranged above the fixing seat 2 in a liftable manner to clamp the terminal located on the welding bottom die 4 with adjustable width; when the terminal clamping assembly 6 clamps the terminal located on the welding bottom die 4, and the wire harness is arranged on the terminal and clamped by the wire harness clamping assembly 5, the ultrasonic welding module 3 moves down to ultrasonically weld the wire harness and the terminal.

[0030] The desktop ultrasonic metal welding machine of the utility model has a compact overall structure. The welding machine can be placed on a work surface through the bearing table 1 to carry out relevant experimental operations, thus meeting actual usage requirements. The terminal clamping assembly 6 can also automatically adjust the welding width of the terminal, making the operation convenient and labor-saving, and the processing efficiency high.

[0031] In this embodiment, the bottom of the bearing table 1 is flat, so that the welding machine can be stably placed on any horizontal work surface to carry out corresponding experimental processing.

[0032] In addition, a plurality of suction cups may be provided on the bottom surface of the bearing table 1, and the welding machine may be stably fixed on the corresponding work surface through the suction cups to meet actual use requirements.

[0033] based on Figure 1 and Figure 4 In this embodiment, the ultrasonic welding module 3 includes an ultrasonic generator 31 disposed on a fixed seat and capable of being raised and lowered by a servo electric cylinder 30; the ultrasonic generator 31 and the welding bottom mold are disposed vertically relative to each other, and an ultrasonic welding head 32 capable of being moved forward and backward is disposed at the welding end of the ultrasonic device 31. In this way, when working, the servo electric cylinder 30 drives the ultrasonic welding head 32 to move downward, thereby welding the wire harness to the terminal. The servo electric cylinder is used to drive the welding machine, so the welding is more stable and the welding pressure is easier to control.

[0034] based on Figure 4 and Figure 5 In this embodiment, the harness clamping assembly 5 includes a lifting plate 52 which is arranged on two harness slide rails 51 and can be lifted and lowered by a harness lifting cylinder 50. The two harness slide rails 51 are arranged in parallel on the fixing seat 2. Two sets of driving units are arranged opposite to each other on the lifting plate 52. The two sets of driving units are used to drive two clamping claws 56 to clamp the two ends of the terminal. Specifically, the driving unit includes a driving motor 53, and the driving motor 53 drives a moving block 55 located on a screw rod 54 to move horizontally. The screw rod 54 is arranged horizontally on the lifting plate 52. The moving block 55 extends from the bottom of the lifting plate 52 and is connected to the clamping claw 56. During operation, when the terminal is placed on the welding bottom mold 4, the two clamping claws 56 drive the screw rods through the two driving motors to drive the two clamping claws to move synchronously toward each other, thereby clamping the terminal. If driven by the driving motor, the clamping speed is stable and the clamping force is stable.

[0035] Based on this, multiple positions are pre-set inside the drive motor 53 to correspond to terminals of different widths, and the positions are fed back through the driver signal. That is, when the two clamping claws 56 move to the set position, if there is no driver signal feedback, it means that the terminal is not clamped at this time, that is, the width of the terminal is not correct, and then the drive motor 53 continues to drive the two clamping claws to move closer to each other to the next position. If there is a driver signal feedback at this time, the clamping claws will not continue to move, so that the terminals of different specifications can be automatically adjusted according to the set terminal width to clamp, which is convenient and labor-saving to operate.

[0036] based on Figure 2 In this embodiment, the terminal clamping assembly 6 includes a clamping seat 60, a lifting platform is provided inside the clamping seat 60, and two clamping blocks 61 that can be clamped to each other by pneumatic fingers are provided on the lifting platform. During installation, the wire harness is passed through the two clamping blocks 61 and placed on the terminal, and then the pneumatic fingers drive the two clamping blocks 61 to clamp the wire harness, which is convenient for subsequent ultrasonic welding.

[0037] In addition, the lifting table is manually liftable by a hand wheel 62 in the clamping seat 60, so that the welding height of the wire harness can be adjusted, which is convenient for welding on the work surface. The hand wheel can also facilitate practical use by adjusting the height of the wire harness.

[0038] based on Figure 2 The top of the welding bottom mold 4 is serrated. This is because vibration will be generated during ultrasonic welding, which will cause the terminal to shift. This design is to increase the stability of the welding terminal.

[0039] During actual work, first place the welding machine on any work surface and fix it by suction through the suction cup.

[0040] Next, the terminal to be processed is placed on the welding bottom die 4, and then the two clamping claws 56 automatically adjust the width under the drive of the two driving motors to clamp the corresponding two ends of the terminal.

[0041] The wire harness is manually passed between the two clamping blocks 61 and one end of the wire harness is placed above the terminal. The height of the wire harness can be adjusted by a hand wheel.

[0042] After the ultrasonic welding device 31 is driven downward by the servo electric cylinder, the pressure is stabilized to weld the wire harness to the terminal.

[0043] In summary, this metal welding machine has a compact overall structure and can be conveniently placed on a work surface, and then the wire harness and the terminal are welded, which is convenient for carrying out related experimental operations; at the same time, the two clamping claws can automatically adjust the position according to terminals of different widths, which is convenient and labor-saving to operate.

[0044] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
