Abstract

PURPOSE:To weld firmly without damaging a wire mesh peripheral section by providing a projection line for positioning on the outside of a crest projection line projectingly provided on a welding section of a wire mesh for a plastic part, melting the projection line and covering a mesh end section with the melt. CONSTITUTION:A lower section material 1' of an outer case of an oil filter for a car is constituted of thermoplastic, for example, a nylon resin molded material, and a couple of section crest projection lines 12 are molded telescopically inside a wire mesh welding surface 11 and a projection line 13 for positioning the height higher than that of the crest projection line 12 slightly closer side of the periphery of the crest projection line 12. The wire mesh 2 for a filter is usually made of stainless steel, and its peripheral section 21 is placed on the crest projection line 12, and its peripheral edge is set in the given position by the projection line 13 for positioning. A supersonic horn 3' is installed crossing the crest projection line 13 and the projection line 13 for positioning, and when the same is oscillated and pressed simultaneously, the projection line 13 for positioning is melted and turned around upwardly in a manner of wrapping the mesh peripheral section 21. Simultaneously, the crest projection line 12 is melted and integrated with molten resin turned around to weld the mesh peripheral section 21 from both of its surface and rear surface.

The edges of the wire mesh 2 are susceptible to vibration and tearing during welding with the ultrasonic horn, causing damage such as tearing, and the resin on the molten protrusions may not be able to fully wrap around the back of the wire mesh, resulting in a lack of welding strength. There is a problem. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for welding wire mesh to plastic parts that does not damage the wire mesh and provides sufficient welding strength even when welding is performed using an ultrasonic horn.

This method was developed based on the fact that the above problem could be solved by covering the thermoplastic plastic molded body with a wire gauze. A positioning protrusion is provided on the outside of the wire mesh, located slightly outside the outer peripheral shape of the wire mesh, and is higher by a predetermined dimension than the height of the protrusion plus the thickness of the wire mesh, and at least has a pressing tool with a width that covers both of the protrusions. The present invention provides a method for welding wire mesh to plastic parts, the gist of which is to melt and fix both protrusions.

The melted bead wraps around the ends of the wire mesh, and then the chevron-shaped protrusions melt and weld the wire mesh together.

以下、本発明を添付図面に示す具体例に基づ

It is molded into. Moreover, around the slightly outer side of the chevron-shaped protrusion 12, there is a positioning protrusion 1 that exceeds the height of the chevron-shaped protrusion 12 (approximately 0.2 to 0.3 mm in the drawing).

When the protrusions 13 are placed oppositely across both protrusions, and pressed at the same time while oscillating under the following conditions, the positioning protrusions 13 melt first before the chevron protrusions 12, and the peripheral edge of the wire mesh melts. It will go around to the upper side so as to wrap around 21. At the same time, the chevron-shaped protrusions 12 begin to melt, and together with the molten resin that has passed around, weld the peripheral edge portion 21 of the wire mesh from its front and back surfaces.

向上することになる。Ultrasonic horn welding conditions Horn amplitude: 50μm Oscillation frequency: 20kHz Horn material: duralumin Pressure force: 5Kg/cm 2 (Effects of the invention) As is clear from the above explanation, in the present invention, welding of wire mesh of plastic parts A positioning protrusion is separately provided on the outside of the chevron-shaped protrusion that protrudes from the ridge, and both protrusions are melted and fixed using a pressing tool with a width that at least covers both protrusions. This positioning protrusion melts before the chevron protrusion, and the melted bead wraps around the end of the wire mesh, whereas the chevron protrusion melts before the chevron protrusion. The two are melted and welded together to form a wire mesh. Moreover, since no welding residue is generated, the welding becomes strong. In particular, when an ultrasonic horn is used as the pressing tool, the peripheral edge of the wire mesh is not damaged, so the product yield is significantly improved.
