Problems solved by technology

However, due to the epidemic, the demand for mask machines has increased sharply, and the use of piezoelectric ceramics, the driving source material for ultrasonic probes, has also increased sharply. As a result, piezoelectric ceramics on the market were out of stock for a period of time, and the price skyrocketed several times. Therefore, finding a new driving source material has become a real problem that needs to be considered.

Embodiment 1

[0018] see figure 1 and figure 2 As shown, the specific disclosure of the embodiments of the present invention provides a technical solution of an ultrasonic welding probe using a magnetostrictive material as a driving source, which mainly includes: a horn 1, a magnetostrictive cylinder 2, a coil 3 and a rear cover Plate 4; the upper end of the horn 1 is abutted with a magnetostrictive cylinder 2, and the outside of the magnetostrictive cylinder 2 is sleeved and wound with a coil 3, and the upper end of the magnetostrictive cylinder 2 also includes a compressed rear cover plate 4.

[0019] In this embodiment, the magnetostrictive cylinder 3 is a cylinder made of magnetostrictive material. It also includes a prestressed screw 5 and a lock nut 6. The inside of the upper end of the horn 1 also includes a screw hole, through which a prestressed screw 5 is threaded, and the upper end of the prestressed screw 5 passes through the magnetostrictive column in turn. The shaft cavity...

Abstract

The invention relates to the technical field of ultrasonic welding probes, in particular to an ultrasonic welding probe using a magnetostrictive material as a driving source, which mainly comprises an amplitude-change pole, a magnetostrictive cylinder, a coil and a rear cover plate, the upper end of the amplitude-change pole abuts against the magnetostriction column, the magnetostriction column is sleeved with the coil in a wound mode, and the upper end of the magnetostriction column further comprises the compressed rear cover plate. The material is higher in power capacity and lower in sound velocity, so that the use volume and the mass of the material can be greatly reduced, and the material can be used as another available driving source material of the ultrasonic welding probe.

Description

technical field [0001] The invention relates to the technical field of ultrasonic welding probes, in particular to an ultrasonic welding probe using a magnetostrictive material as a driving source. Background technique [0002] In recent years, the new crown epidemic has continued to spread, and medical masks have become a daily necessity for people, and the consumption is relatively large. Therefore, the demand for machines for making masks has also increased. One of the most important components is the ultrasonic welding probe. Through Ultrasonic energy can make the surfaces of two objects merge with each other under pressure, so that the produced masks have beautiful appearance, uniform trimming, firm welding strips, and ergonomics. However, due to the epidemic, the demand for mask machines has increased sharply, and the use of piezoelectric ceramics, the driving source material for ultrasonic probes, has also increased sharply. As a result, piezoelectric ceramics on the ...
