Description

Technical Field

[0001] The utility model belongs to the technical field of indium coating, and in particular relates to ultrasonic automatic indium coating equipment. Background Art

[0002] Rare metal indium is extremely soft and has good light permeability and conductivity. It is widely used in new semiconductor alloys, solar cells, optical fiber communications, atomic energy, aerospace technology, computers, televisions, anti-corrosion and other technical fields. In actual production applications, customers need to coat the inner wall of the pipe with indium, but the general method cannot achieve effective coating on the inner wall of the pipe and is easy to fall off. By using ultrasonic technology to coat the pipe with indium, the problems of uniform coating and adhesion can be effectively solved, so that a balanced indium coating layer can be obtained on the inner wall of the pipe, and the indium coating efficiency is high.

[0003] At present, the existing ultrasonic indium coating process is divided into manual and automatic control. Manual control of indium coating will affect the efficiency and uniformity of coating, while automatic control has the characteristics of uniform coating, convenient control and labor saving. Patent application number "202110781854.8" discloses an automatic ultrasonic indium coating equipment, including an ultrasonic indium coating device, a sliding platform and a support table. The ultrasonic indium coating device includes an ultrasonic vibration system and an indium tank. The ultrasonic vibration head of the ultrasonic vibration system extends into the indium tank. The indium tank is used to accommodate indium liquid. The vibration head seat of the ultrasonic vibration system is connected to the sliding platform. The sliding platform is used to drive the ultrasonic indium coating device to move along a preset direction and coat the object to be coated with indium, which can realize linear movement spraying. However, the patented device has a fixed spacing and cannot be applied to pipes of different sizes and lengths. It is troublesome to change the fixture according to the pipe, which is time-consuming and laborious. In addition, the existing ultrasonic indium coating equipment is mostly fixed structure, which is inconvenient to move. In addition, due to the lack of heating device for the pipe, the indium liquid will solidify quickly due to contact with the inner wall of the pipe, thereby affecting the indium coating efficiency and solidification time, resulting in uneven spraying. Therefore, the existing ultrasonic indium coating equipment structure needs to be further improved. Utility Model Content
