Plastic welding movable arm

Abstract

The invention provides a plastic welding movable arm. The plastic welding movable arm comprises a laser welding gun, a flash swing device assembly, a swing arm assembly, a vertical arm assembly, a stroke vehicle assembly and an industrial personal computer. The laser welding gun is arranged on a flash swing device shaft of the flash swing device assembly through a welding gun support, the flash swing device shaft is in transmission connection with the flash swing device driving mechanism, the swing arm assembly comprises a swing arm body, a swing arm bracket, a swing arm shaft and a swing arm driving mechanism, and the swing arm driving mechanism drives the swing arm shaft and the swing arm body to swing. The vertical arm assembly comprises a vertical arm body, a vertical arm linear guide rail and a vertical arm driving mechanism. The stroke vehicle assembly comprises a frame bottom plate, a longitudinal linear guide rail, a transverse linear guide rail and a stroke vehicle driving mechanism. According to the plastic welding movable arm, multi-degree-of-freedom movable welding can be achieved, the plastic welding movable arm adapts to welding of workpieces with complex welding paths, the flash swing device assembly can simulate the welding mode of manual welding, the welding quality can be improved, and the labor cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of thermoplastic materials, in particular to a plastic welding movable arm for welding thermoplastic workpieces. Background technique [0002] Plastics are non-metals, man-made organic materials, and one or more polymers with high molecular weight as the main components. The direct product of plastic is a solid or liquid resin, which is usually processed into a plastic masterbatch formed by powder, granule or paste, and mixed with a certain amount of additives, and then under higher temperature or pressure conditions It is processed into plastic profiles or plastic products. According to the chemical composition, properties and temperature effects of plastics, they are usually divided into two categories: thermoplastics and thermosetting plastics. The welding of plastics actually refers to the welding of thermoplastics; thermoplastics can also be divided into crystalline and amorphous plastics. Since the c...

Problems solved by technology

Since thermoplastic workpieces can be formed into complex cross-sections at one time, the welding path is often complicated, and it is difficult for general welding devices to meet the requirements

In addition, thermoplastic workpieces are easily deformed by heat, so that the welding position will deviate due to uncontrollable thermal deformation during the welding process, which seriously affects the quality of the weld
