[0028] At both ends of the top of the skateboard 3, a quick die change machine 6 is installed. By setting the quick die change machine 6, it is convenient to quickly change the die for the upper template 25. At both ends of the center of the top surface of the skateboard 3, upper die positioning holes 7 are provided, and positioning blocks are clamped inside the upper die positioning holes 7, which is convenient for positioning and installing the upper template 25, and also convenient for disassembling and installing the upper template 25. The bottom of the positioning block is fixedly installed with the upper template 25, and at both ends of the bottom of the upper template 25, a second electric telescopic rod 10 is installed. The output end of the second electric telescopic rod 10 is installed with a mounting plate, and on one side of the mounting plate, an ultrasonic welding machine 11 is installed by screws.

[0029] Principle of the ultrasonic welding machine 11: The generator generates high-voltage and high-frequency signals of 20KHz or 15KHz. Through the transducer system, the signals are converted into high-frequency mechanical vibrations and applied to the products to be welded. Through the friction between the surfaces of the products and between molecules, the temperature at the interface is increased. When the temperature reaches the melting point of the product itself, the welding position of the product quickly melts and then fills the gaps at the welding position. When the vibration stops, the product is cooled and shaped under a certain pressure at the same time, thus achieving high-quality welding.

[0030] By setting components such as the skateboard 3, the quick die change machine 6, the upper die positioning holes 7, and the upper template 25 to cooperate with each other, the present utility model is convenient to realize the function of automatic and quick die change, so as to improve the efficiency of product loading. By setting the ultrasonic welding machine 11, the present utility model is convenient to improve the welding efficiency and quality of the products, and moreover, saves a certain welding cycle and reduces the input cost.

And the surface of the lower template 16 is fixed by being stuck in the lower die positioning holes, which is also convenient for disassembling and installing the lower template 16.

[0032] Put the ultrasonic welding tooling into the welding equipment. The skateboard 3 in the equipment returns to the origin position. The upper template 25 and the lower template 16 on the tooling are separated, and the corresponding products are put in. Press the equipment button 15, and the skateboard 3 in the equipment descends and the tooling closes the die, and the ultrasonic mechanism completes the ultrasonic welding required for the products.

[0033] A guide post base 8 is fixedly installed around the top of the lower template 16, and a guide post sleeve 9 is sleeved at the center of the guide post base 8.

Fourth electric telescopic rods 24 are installed at both front ends of the top of the lower template 16, and the output ends of the fourth electric telescopic rods 24 extend into the interior of the positioning seat 19.

[0034] By starting the third electric telescopic rod 20, its output end drives the placement plate 18 to move back and forth on the guide rail 17 for adjustment, so that the placement plate 18 moves below another ultrasonic welding machine 11, thereby improving its applicability and welding efficiency. And when moving, the extension plate 21 on the placement plate 18 moves in the limit seat 22 at the same time, so as to facilitate its limitation.

[0036] By starting the third electric telescopic rod 20, its output end moves into the positioning seat 19 arranged at the bottom of the placement plate 18, so as to play a role in positioning and fixing the placement plate 18, thereby improving the stability and quality of the product during ultrasonic welding.

[0037] Working principle:

[0038] Put the ultrasonic welding tooling into the welding equipment. The slide plate 3 in the equipment returns to the origin position.
