Benefits of technology

The technical effect of this innovation is that it allows for better joining of different materials during fusion bonding without compromising their quality or functionality. This results in improved durability over longer periods of use compared with traditional methods like glue joints.

Problems solved by technology

This patents describes how plastisolids like epoxy or polyamide can be easily formed from liquid crystals called lithium nioborate. These liquids consists mostly of small particles - but there're many other substances involved such as organic acids, bases, amines, metal salts, etc., making them difficult to process directly without causing damage during their formation. Additionally, current methods require specialized equipment and techniques, limiting its use beyond specific applications where certain characteristics make it necessary.

Embodiment Construction

[0021] The plastic laser welding method of the present invention is mainly for welding thermosetting plastics, and is used to expand the application of laser welding on thermosetting plastics.

[0022] Such as figure 2 Shown is the schematic diagram of the present invention, the plastic welding device includes materials to be welded, and the materials to be welded include an upper layer of material 2 made of a light-transmitting material, a lower layer of material 4 made of an opaque material, and a layer of material located between the upper layer of material 2 and the lower layer The hot-melt tape 3 between the materials 4, the hot-melt tape is located at the position to be welded of the lower layer material 4, and the hot-melt tape 3 connects the upper layer material 2 and the lower layer material 4. The laser beam 1 acts on the upper material 2 to be welded.

[0023] The adhesive tape 3 can also be a thermosetting adhesive tape.

[0024] After the laser beam 1 passes throu

Abstract

The invention discloses a plastic welding device and a laser welding method thereof. The plastic welding device comprises a welding device. A to-be-welded material comprises an upper layer material body made of a transmitting material, a lower layer material body made of a non-transparent material and adhesive tape located between the upper layer material body and the lower layer material body. The adhesive tape is located at a to-be-welded position of the lower layer material body, and the adhesive tape is connected with the upper layer material body and the lower layer material body. According to the plastic welding device and the laser welding method thereof, the hot-melting adhesive tape is added into the position between the to-be-welded plastics and heating and melting are conductedby using laser, and therefore thermosetting plastics can be welded together; and at the same time, the product waterproofness and the airtightness can be effectively improved through adhesive tape connection, the product heat affected zone can further be effectively narrowed through laser local heating, and the situation that other positions of a product are affected by the high temperature is avoided.
