[0022] As Figure 1-2As shown in the figure, an ultrasonic welding machine for sheet metal processing includes a control box 1. A workbench 4 is installed at the upper end of the control box 1, and a welding table 5 is installed on the upper end of the workbench 4 through a moving mechanism 6. Two groups of clamps are symmetrically arranged in the front-rear direction on the welding table 5. Each group of clamps consists of symmetrically distributed clamp blocks 11. A tooling 12 is placed between the clamp blocks 11, and a workpiece for welding is placed on the tooling 12. In this embodiment, the workpiece is mainly a PS sheet. A support column 7 is installed at the rear position of the upper end of the workbench 4. A telescopic mechanism 8 is installed at the upper end of the support column 7. An ultrasonic generator 9 is installed at the telescopic end of the telescopic mechanism 8. A plurality of symmetrically distributed welding heads 10 are installed at the lower end of the ultrasonic generator 9.

[0023] The ultrasonic generator 9 transmits high-frequency vibration waves to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects rub against each other to form a fusion between the molecular layers. The entire welding cycle is usually less than one second, but the welding strength is close to that of an integral material, thus greatly improving the production efficiency. In addition, ultrasonic welding does not require the use of additives such as glue and adhesives, so it can reduce environmental pollution and also save unnecessary power energy consumption, meeting the environmental protection requirements.

[0024] As Figures 3-5 shown in the figure, the moving mechanism 6 includes a front-rear moving mechanism 602 installed below the welding table 5 and a left-right moving mechanism 601 installed below the front-rear moving mechanism 602.

[0025] The left-right moving mechanism 601 and the front-rear moving mechanism 602 have the same structure. Both include a channel-shaped table 605. Two symmetrically arranged slide rails 606 are installed at both ends of the channel-shaped table 605. A slider 607 is slidably installed on the slide rails 606. The tops of the sliders 607 are connected together through a fixed table 603. A nut 609 is installed at the center position of the bottom of the fixed table 603. The nut 609 is threadedly connected to a lead screw 608. One end of the lead screw 608 is fixedly connected to a motor 604, and the other end is rotatably installed on the channel-shaped table 605. The motor 604 is a forward and reverse motor.

[0026] By driving the lead screw 608 to rotate through the motor 604, according to the lead screw principle, the nut 609 moves along the lead screw 608 under the action of the slide rails 606 and the sliders 607, thereby realizing the movement of the fixed table 603 and meeting the left-right and front-rear movement of the workpiece during the welding process.

[0027] An electronic control component is installed inside the control box 1. A switch button 2 and an electronic control screen 3 are installed on the front outer wall of the control box 1.

[0028] The electronic control component is electrically connected to the switch button 2, the electronic control screen 3, the moving mechanism 6, the telescopic mechanism 8, and the ultrasonic generator 9.

[0029] The telescopic mechanism 8 uses a cylinder.

[0030] The number of several welding heads 10 is two, and the distance between the welding heads 10 is fixed. During the actual processing, according to the different requirements of the processing distance of the welding heads 10, the welding heads that meet the requirements can be replaced at any time.

[0031] The operation process of the present utility model is as follows:

[0032] First, place the tooling 12 on the welding table 5 and clamp it between the fixture blocks 11; then, place a layer of barrier film on the upper surface of the tooling 12 to prevent the workpiece from being welded to the tooling 12; finally, place the workpieces to be welded together on the upper layer of the film, and start the ultrasonic generator 9 according to the pre-designed welding points to weld the PS plates together.

[0033] The above-described embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
