Description

Technical Field

[0001] The utility model relates to the technical field of laser plastic welding, in particular to an internal and external pressure fixture bridged by a steel wire. Background Art

[0002] Laser plastic welding, as a new type of plastic connection processing technology, has been widely used and promoted in the industrial field in recent years. Its basic principle is to press and fix two plastics with different light transmittances together through the positioning of tooling fixtures. The laser penetrates the upper layer of high-transmittance plastic and is absorbed by the lower layer of low-transmittance plastic. The laser light energy is converted into heat energy to melt the contact area, forming a welding area to combine and fix the upper and lower layers of plastic.

[0003] A Chinese patent with a search announcement number of CN220114040U discloses a laser plastic welding tool, including a profiling frame, a bottom plate is horizontally slidably installed in the profiling frame, a lifting plate is vertically slidably installed on the bottom plate, a quick-change base is arranged on the lifting plate, and the quick-change base can be divided into an upper and lower part, a mounting plate is fixedly installed on the upper half of the quick-change base, a profiling base is fixedly installed on the mounting plate, a profiling cover is arranged on the top of the profiling frame, and the profiling cover can press the workpiece. The tool is installed on a workbench and cooperates with the guide rail, and is convenient to clamp and install. The overall design ensures the precision requirements and is convenient for product changeover. Laser plastic welding can be completed by one clamping, and production can be completed conveniently, quickly and efficiently.

[0004] However, when performing laser plastic welding, this type of laser plastic welding tooling needs to use a fixture to perform internal and external pressure on the upper cover of the product. The inner pressure block and the outer pressure block are connected by steel sheets. Since the steel sheets have a certain width, when the laser is irradiated from different angles, the steel sheets have a large shading effect, thereby affecting the final laser welding effect.
