Detailed ways

Below in conjunction with specific embodiment and accompanying drawing, the utility model is described further.

The soft silicone gasket 6 and the ear shell 8 belong to the electro-acoustic components. The soft silicone gasket 6 is a closed regular band structure. During the assembly process of the electro-acoustic components, the soft silicone gasket 6 needs to be attached to the ear shell 8 combine.

This embodiment provides an auxiliary jig for attaching the soft silicone gasket to the ear shell, which plays an auxiliary role in the process of attaching the soft silicone gasket to the ear shell. Its basic structure includes a machine platform 1, and the machine platform 1 has a cylindrical structure as a whole. Please refer to attached drawings 1 and 2 for details.

The side wall of machine platform 1 is provided with power switch 11, after plugging in power supply, can control power-on by opening and closing power switch 11.

The top surface of the machine table 1 is a horizontal plane, and the top surface of the machine table 1 is provided with an adsorption jig bottom 2 and an adsorption jig 3 sequentially from bottom to top. In this embodiment, the cross-sections of the adsorption jig bottom 2 and the adsorption jig 3 are similar to rectangles, and the corners of the cross-sections are rounded, which is not easy to scratch the workers.

There is a horizontal extension side below the bottom 2 of the adsorption fixture, and each of the four corners of the horizontal extension side is provided with a screw hole, and a screw is inserted into each of the four screw holes to fix the bottom 2 of the adsorption fixture on the top surface of the machine 1 the central place.

The adsorption fixture 3 is stuck on the top of the adsorption fixture bottom 2, and the adsorption fixture 3 and the adsorption fixture bottom 2 are connected up and down through screw holes and screws. The interior of the adsorption jig 3 and the bottom 2 of the adsorption jig is a hollow structure. A vertical pneumatic mechanism 4 and a spring 5 are arranged between the adsorption jig bottom 2 and the adsorption jig 3 .

The pneumatic mechanism 4 is electrically connected to the drive control system, which is set inside the machine 1, and the pneumatic mechanism 4 is controlled by the drive control system.

A positioning mechanism 31 for fixing the soft silicone gasket 6 is provided on the top surface of the adsorption jig 3 , and the positioning mechanism 31 is connected with the adsorption jig 3 in a limited position.

The positioning mechanism 31 is a regular-shaped boss, and the shape of the outer edge of the boss matches the inner edge of the soft silicone pad 6 . Putting the soft silicone pad 6 on the outer edge of the positioning mechanism 31 can position the soft silicone pad 6 . The positioning mechanism 31 can also position the concha 8 .

The pneumatic mechanism 4 is vertically arranged below the range where the soft silicone gasket 6 is positioned. The pneumatic mechanism 4 is preferably a cylinder.
