保持される超音波溶接方法が望まれていた。 Generally, when welding using the frictional heat generated within plastic parts using ultrasonic vibrations, a protrusion called an energy director is provided at an arbitrary point on the plastic part to concentrate the ultrasonic vibrations. However, adding an energy director increases the manufacturing cost of the material, so an ultrasonic welding method that allows flat plates to be welded together without adding an energy director and maintains flatness after welding has been developed. was desired.

た。 The conventional method of ultrasonic welding between flat plates involves rounding the end face of the sound and sliding this end face over the overlapping part of the plastic member, or using a sound pole on a disc to roll the overlapping part of the plastic member. However, with these methods, distortion occurred in the portion of the sound end surface that touched the surface, and favorable results in terms of overall flatness could not be obtained. In particular, there have been problems in welding between plates that require strict flatness, such as the mount and mount cover for chemical analysis slides used for chemical analysis of liquid samples such as blood and serum.

It is said that

The flat end face of the sound pole can correct the distortion that occurs on the surface of the plastic member when it bites into the sound pole.

5, it is fitted from the outer surface side of one plastic member 4 and has a height such that it can cut into the other plastic member 5 beyond the joint surface 6. That is, if the height of the small protrusion 3 is H, and the thicknesses of one plastic member 4 and the other plastic member 5 are a and b, then a<H<a+b.

For example, as shown in Figure 2, when the sound poles are arranged only at the four corners of the end face 2 of the sound pole 1, when they are arranged along the four sides of the sound end face 2 as shown in the figure, In some cases, they are arranged in a grid pattern. Furthermore, although the small protrusions 3 have a prismatic shape in the illustrated example, they may have a cylindrical shape, a triangular prism shape, or any other shape (for example, a conical shape, a pyramidal shape, etc.).

is positioned perpendicular to the joint surface 6 of the plastic parts 4, 5. Next, while applying vertical ultrasonic vibration from a coupling part (not shown) to the small protrusion 3 on the end surface 2 of the sound pole 1, as shown in the figure, the outer surface of the one plastic member 4 is Insert the small protrusion 3 from the outer surface side of one plastic member 4 to the depth where the sound pole 1 is crimped, and then
the other plastic member 5. Frictional heat is generated within the plastic members 4 and 5 due to the biting of the small protrusions 3 and the ultrasonic vibrations, causing them to melt. At this time, the distortion 7 of the plastic member 4 increases around the biting of the small protrusion 3;
By further applying pressure to the sound pole 1 and crimping its end face 2 to the upper surface of the plastic member 4 as shown in the figure, the distortion 7 is corrected by the sound end face 2, and the small protrusion 3 is attached to the plastic member 4. ，
It penetrates the joint surface 6 of 5 and completely welds both. At this time, a volume corresponding to the small protrusion 3 flows between the plastic members 4 and 5, causing some
form a gap. However, this period can be eliminated by adjusting the welding conditions. After this welding is completed, the small protrusions 3 that have bitten into the plastic members 4 and 5 are removed, but in order to facilitate this removal work, for example, the upper surface of the welded object may be supported by a certain jig or the like. It is best to do this while keeping the sound pole 1 oscillating. It is also conceivable to make the small protrusion 3 into a shape that is easy to remove.

要求される部材間の溶接に特に有効である。 As described above, according to the ultrasonic welding method of the present invention, two pieces of plastic members that are to be joined to each other on a plane are fitted into the flat sound end face from the outer surface side of one side, and the other is inserted beyond the joint face. A small protrusion having a height that can be bit into the one member is provided, and the small protrusion is inserted in a direction perpendicular to the bonding surface while applying ultrasonic vibration to a depth where the sound end surface is crimped to the outer surface of the one member. This feature allows flat plates to be reliably welded together, and although a group of small holes corresponding to small protrusions are formed in the plastic member after welding, the overall flatness is completely the same as before welding. A welded product with high precision and good quality can be obtained without any difference. Therefore, it is particularly effective for welding between parts that require strict flatness in the product after welding, such as the mount and mount cover of a chemical analysis slide used for chemical analysis of liquid samples such as blood and serum.
