Abstract

The invention discloses a painting machine of rims of a lens and a painting method. The method is characterized in that light sources enter a lens to be painted through a cross-shaped differential board, transmit to an imaging system, and form a cross-shaped image on a CCD (charge coupled device); a silk screen printing box is placed at the side surface to be painted, one surface with a silk screen faces to the rims of the lens to be painted and is parallel to the central axis of the lens, and the silk screen paint penetrating width is equal to or greater than the rim thickness of the lens to be painted; the silk screen printing box is filled with sponge, and diluted ink is put in the sponge; when vacuum absorbs the lens to be painted and the crossed-shaped image is rotatably regulated to be static, the silk screen printed box filled with oil ink is contact with the rims of the lens to be painted and squeezes, the vacuum absorption lens to be painted rotates, and the whole rims squeeze the silk screen, thus ink is uniformly painted to the rims of the lens. The structure is simple, the painting thickness is uniform, and the manufacturing is convenient.

Description

A kind of rims of the lens method of lacquering

Technical field

The present invention relates to the optics manufacture field, especially a kind of rims of the lens method of lacquering in the optics processing.

Background technology

The rims of the lens japanning is in order to control parasitic light, improve signal to noise ratio (S/N ratio), to improve contrast.

Parasitic light is present in the edge of the optical element in imaging system and the electro-optical system, and the noise in the signal is increased, and influences the contrast of system.Coating black delustring lacquer or ink can reduce parasitic light at the edge of optical element, improve signal to noise ratio (S/N ratio).

Present method of lacquering is: a kind of be oil pen with black in the blacking of the edge of lens, the operating process of this kind method is long, efficient is low, and the edge be coated with black inadequately, have light leakage phenomena.

A kind of in addition method is to adopt lacquer spraying technique, is sprayed onto rims of the lens with spray gun, wipes the black paint of logical optical surface then.This kind method has increased the lacquer of wiping logical light face, inconvenient operation, deface quality easily; And the degree of uniformity that sprays paint is different, and edge lacquer variable thickness causes, and so-called ovality is bad.

Summary of the invention

The object of the present invention is to provide a kind of rims of the lens coating machine and method of lacquering, make things convenient for rims of the lens japanning processing, and japanning is evenly simple to operate.

The technical solution adopted for the present invention to solve the technical problems is: light source incides lens to be painted through cross differentiation plate, is transmitted to imaging system, on CCD, becomes the cross picture.Place a serigraphy box in side to be painted; The edge of the one side of silk screen towards lens to be painted arranged, parallel with the lens center axle, and silk screen to coat with lacquer width thoroughly the same or bigger than normal with the edge thickness of lens to be painted; Filling sponge in the serigraphy box, the printing ink of dilution is placed in the sponge.

The suction of taking seriously attaches lens to be painted; And rotate to regulate cross when motionless, and the serigraphy box contact that printing ink is housed waits to be coated with the edge and the extruding of lens, and vacuum suction lens to be painted rotate; Whole edge extruding silk screen, thus printing ink is coated with the edge that is coated onto lens uniformly.

Further, go out what of quantity of ink, can regulate amount of compression or change the order number of silk screen.

Further, the printing ink that printing ink can adopt UV to solidify with the UV printing ink that rims of the lens coats, adopts the UV light source to solidify, and is easy to operate.

Description of drawings

Fig. 1 is one of structural representation of a kind of rims of the lens coating machine of the present invention and method of lacquering.

Embodiment

Like Fig. 1,101 is visible light source, and 102 is collimating apparatus, and 103 is cross differentiation plate, and 104 are absorption lens holder to be painted, and 105 is lens to be painted, and 106 is imaging lens, and 107 is CCD, and 108 is screen printing net plate, and 109 are sponge filling printing ink.Light source 101 visible light emitted become directional light through collimating device collimation, incide lens 105 to be painted through cross differentiation plate 103, finally pass through imaging lens, use CCD107 to show.Anchor clamps 104 vacuum suction lens 105 to be painted, position that rotate to regulate lens to be painted up to the cross picture till motionless in the imaging system, at this moment, the center line of lens to be painted and mechanical axis coincidence.

The silk screen face of screen printing net plate 108 is towards lens to be painted, filling sponge in the screen printing net plate, and sponge fully absorbs the UV printing ink that diluted, and the width of silk screen strike through is more than or equal to the thickness of rims of the lens.

Screen printing net plate 108 is moved to the lateral edge of lens to be painted, and the lens to be painted of vacuum suction rotate, the extruding silk screen, and UV printing ink overflows from silk screen, is coated in the edge of lens to be painted uniformly, then with UV curing printing ink such as ultraviolets.

Claims

1. rims of the lens coating machine and method of lacquering are placed a serigraphy box in side to be painted, and the edge of the one side of silk screen towards lens to be painted arranged; The printing ink of dilution is placed in the sponge, and the suction of taking seriously attaches lens to be painted, and rotates and regulate cross when motionless; The serigraphy box contact that printing ink is housed waits to be coated with the edge and the extruding of lens; Vacuum suction lens to be painted rotate, whole edge extruding silk screen, thus printing ink is coated with the edge that is coated onto lens uniformly.

2. it is characterized in that: light source incides lens to be painted through cross differentiation plate, is transmitted to imaging system, on CCD, becomes the cross picture.

3. a kind of rims of the lens coating machine according to claim 1 and method of lacquering is characterized in that: filling sponge in the serigraphy box.

4. a kind of rims of the lens coating machine according to claim 1 and method of lacquering is characterized in that: the order number of silk screen is at the 200-800 order.

5. a kind of rims of the lens coating machine according to claim 1 and method of lacquering, it is characterized in that: silk screen is placed on rims of the lens, and the silk screen face is parallel with the center of lens.

6. a kind of rims of the lens coating machine according to claim 1 and method of lacquering is characterized in that: the width of silk screen is equal to, or greater than the edge thickness of lens.

7. a kind of rims of the lens coating machine according to claim 1 and method of lacquering is characterized in that: the silk screen filling material can be sponge, cotton.
