Description

Technical Field

[0001] The utility model relates to the technical field of lens production, in particular to a glue dispensing tooling fixture. Background Art

[0002] The filter is an optical device in the lens used to filter light and select specific radiation bands. The filter is attached to the surface of the switching blade and moves with the switching blade.

[0003] During the production process, glue is needed to bond the filter to the surface of the switching blade to prevent the filter from loosening. There are two existing glue dispensing methods. The first glue dispensing method is to first drip glue on the switching blade, and then attach the filter to the position of the switching blade where the glue is dripped. This glue dispensing method has some application defects. For example, the glue may solidify prematurely, resulting in unstable bonding, or the glue may block light, resulting in a decrease in the filtering effect. This type of glue dispensing method is generally not used. Another glue dispensing method is to first place the filter on the surface of the switching blade, and then drip glue on the edge of the filter. After the glue solidifies, the filter can be fixed on the switching blade.

[0004] However, when the switching blades or filters are relatively offset, it is easy to cause uneven glue dripping and poor patch effect, which ultimately affects the filtering effect of the lens. Utility Model Content

[0041] like Figures 1 to 7As shown, the present embodiment provides a dispensing tool and fixture, which includes a base plate 1, a limiting plate 2 and a pressing plate 3 which are arranged in sequence from bottom to top. A limiting groove 11 is provided on the top of the base plate 1, and the switching blade 100 is accommodated in the limiting groove 11. The limiting plate 2 is provided with a first opening 21 at a position corresponding to the limiting groove 11, and a limiting platform 22 is provided on the side wall of the first opening 21.

The cantilever beam 31 is provided with a pressing member 4, and the pressing member 4 is used to press the filter 200 against the switching blade 100 in the vertical direction.

[0042] Specifically, after the switching blade 100 is placed in the limiting groove 11, the movement of the switching blade 100 on the horizontal plane is restricted. At this time, the limiting plate 2 is moved to the top of the bottom plate 1 so that the first opening 21 is aligned with the limiting groove 11. At this time, the filter 200 is passed through the first opening 21 and placed on the surface of the switching blade 100 along the side wall of the limiting platform 22. The movement of the filter 200 on the horizontal plane is restricted.
