Ultrasonic welding machine

Abstract

The invention discloses an ultrasonic welding machine. The ultrasonic welding machine comprises a workbench, an ultrasonic welding head, a cooling device and clamping tables. A welding head holder is arranged on the upper surface of the workbench. A controller is arranged on the front side of the welding head holder, a first air cylinder is arranged in the welding head holder, and the lower portion of the front side of the welding head holder is in sliding connection with the ultrasonic welding head. The top of the ultrasonic welding head is fixedly connected with the first air cylinder. The cooling device is arranged on the periphery of the ultrasonic welding head. Sliding grooves are formed in the upper surface of a piston rod of a second air cylinder. Sliding blocks are arranged at the bottoms of the clamping tables respectively. The clamping tables slide in the sliding grooves and are fixed through bolts. Movable stand columns are connected with a motor through movable devices. Pressure sensors are arranged on the inner sides of the movable stand columns. The effect of intelligently controlling the stand columns to be close to the clamping stables can be achieved, and the ultrasonic welding machine can be suitable for welding pipelines with different diameters; the service life of the ultrasonic welding head and the service life of the cooling device can be prolonged easily, and operation by a single person can be better facilitated through a control switch; the ultrasonic welding machine is simple in structure and has remarkable practicality and efficiency.

Description

technical field [0001] The invention relates to the field of a welding device, in particular to an ultrasonic welding machine. Background technique [0002] Ultrasonic welding is a key process of many plastic products, and it plays an irreplaceable key role in modern production, especially in the production industry of injection molded parts. Ultrasonic welding is a necessary equipment, and many parts are welded by ultrasonic. [0003] The existing ultrasonic welding device includes an ultrasonic welding unit, which is inconvenient to operate and cannot be intelligently controlled. When welding the pipes of injection molded parts, the clamping table needs to be replaced frequently due to the different diameters. The stability is not high, and when welding long parts, it needs to be fixed with a column, so as to avoid the influence of inclination during the welding process on the welding. In the existing welding machine, the column needs to be manually pushed, which wastes ma...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an ultrasonic welding machine to solve the defects in the prior art that the generality of the above-mentioned clamping table is not high, the column still needs to be manually pushed and the life of the cooling device is short
