接作業を行なう新規な超音波溶接法に関する。DETAILED DESCRIPTION OF THE INVENTION In ultrasonic welding of ultrasonic welding assemblies with spring repulsive force, the present invention pre-assembles the parts and temporarily fixes them to each other, and then This article relates to a new ultrasonic welding method for performing sonic welding operations.

のである。 When assembling valves with internal spring mechanisms, such as diaphragm valve mechanisms or check valve mechanisms, compared to parts conventionally made by plastic molding, the spring repulsive force becomes an obstacle and welding is relatively difficult. The inventors have discovered that the ultrasonic assembly work can be extremely facilitated and speeded up by pre-assembling the product body and lid using a snap-in structure. In this way, the present invention provides a structure that provides a snap-in mechanism in the ultrasonic welding assembly of a spring-internal valve, thereby preliminarily fixing (temporarily fixing) the parts while maintaining their movability to the extent that they can be welded. , the following concerns an ultrasonic welding method for performing ultrasonic welding assembly.

ることにより修正され、精度が向上する。 According to the method of the present invention, there is no positional shift during welding, which improves accuracy especially when assembling a valve with a built-in spring mechanism, and also eliminates the trouble of setting parts on a welding machine during welding (setting is easy). (in a separate location), thus increasing the efficiency of the welding machine. Also, deformation of plastic parts during molding is corrected by snap-fitting with normal parts during snap-in, improving accuracy.

ついて説明する。 Next, the method of the present invention will be explained with reference to the method of assembling a valve equipped with a spring as shown in the drawings by ultrasonic welding.

不良率が増加する危険が多い。 When assembling valves with internal spring mechanisms, such as the diaphragm valve (Fig. 1) and check valve (Fig. 2) shown in the drawings, the free length of the spring 7 is long, so the body 1 before assembly is If it is not possible to bring the welded portion of the lid (cover) 2 close together before the ultrasonic operation, there is a high risk that the defective rate of the assembly will increase due to the difficulty of accurate positioning.

易になり、成功率も極めて高率で与えられる。 However, as shown in the drawings (see Figures 1A, 2A, and 3), an undercut structure is provided to the body and cover of the molded product during molding, and ultrasonic welding (processing) is carried out. If you snap in and preset all the interior parts before performing ultrasonic welding (pressure oscillation) (Figs. 1B and 2B), the product will be almost ready before ultrasonic welding (pressure oscillation). The normal position is given, making the welding work very easy and the success rate also very high.

ものである。 In this method, the snap-in structure is basically pre-assembled, so although the snap-in lid is pushed up by the spring repulsive force, it has some clearance from the body, and during ultrasonic welding work It is free from sonic vibrations and provides suitable welding results. (See Figures 1B and 2B) In carrying out this method, the designs of the ultrasonic welds are known welding designs: (a) bead joint, (b) scarf joint, (c) energy director, ( d) Any of the sear joints may be used, and pre-assembly is performed by adding the above-mentioned snap-in mechanism to these known designs.
