Embodiment Construction

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and similar expressions are used herein for the purpose of descripti...

Abstract

The invention relates to a transparent plastic welding method. The method comprises the following steps: stacking two transparent plastics to be welded; covering the transparent plastic at the upper layer with a radiating fin; and enabling the laser of which the wavelength is 1700nm-2000nm to sequentially penetrate through the radiating fin and the transparent plastic at the upper layer and focuson the joint surface of the two transparent plastics so as to weld the two transparent plastics together. In the transparent plastic welding method provided by the invention, the laser of which the wavelength is 1700nm-2000nm is adopted for welding the transparent plastics, and the transparent plastics have lower light transmittance to the laser of which the wavelength is 1700nm-2000nm, so that when the transparent plastics are welded, an absorbent does not need to be added so as to improve the welding efficiency; and furthermore, the radiating fin is adopted for performing heat dissipation onthe transparent plastic at the upper layer so as to avoid the transparent plastic at the upper layer from being burnt out due to too high temperature.

Description

technical field [0001] The invention relates to a transparent plastic welding process, in particular to a transparent plastic welding method. Background technique [0002] Plastic is light in weight, strong in chemical corrosion resistance, good in impact resistance, good in insulation and wear resistance, low in manufacturing cost, and easy to process into different shapes. Plastics are used in a wide range of applications, such as product packaging, daily products, pipes, etc. [0003] Due to its high light transmittance, transparent plastics are widely used in lighting equipment, optical instruments, plastic glass, optical fiber materials, optical disc materials, transparent packaging and other fields. For special fields such as optical contact lenses, optical fiber materials, and medical plastics, the cleanliness of plastics is extremely high. The traditional transparent plastic welding methods are ultrasonic welding, friction welding, vibration welding, hot plate weld...
