[0035] In this embodiment, when using the threadless dispensing fixture, the cover plate 3 and positioning plate 2 are first removed. Voice coil motors are placed in the placement slots 11 on the upper end of the base plate 1, with the slot size matching the voice coil motor, thus fixing the voice coil motor within the placement slot 11. Then, the positioning plate 2 is installed on the upper end of the base plate 1, with its lower end fitting against the upper end of the voice coil motor in the placement slot 11, thus fixing the voice coil motor. Next, the lens is installed on the voice coil motor through the mounting holes 21 on the positioning plate 2. After the connector is installed, the dispensing operation between the voice coil motor and the lens can be performed. After dispensing, the cover plate 3 is installed on the upper end of the positioning plate 2, with the bottom wall of the groove 31 abutting against the lens surface. The lens is pressed down, fixing the voice coil motor and the lens. At this time, the positioning plate 2 ensures that multiple voice coil motors are on the same horizontal plane, and the cover plate 3 ensures that multiple lenses are on the same horizontal plane, thus ensuring uniform size of the lens assembly after processing on the threadless dispensing fixture.
