Abstract
The utility model provides a laser projection line cone type optical component which comprises a lens barrel, an aspheric lens, an aperture sheet and a funnel type cone lens. The aperture sheet is adhered on the bottom plane of the funnel type cone lens. The aspheric lens is located in the lens barrel. The funnel type cone lens is arranged at the upper part of the lens barrel. The lens barrel and the aspheric lens are in an integrally molded structure. According to the utility model, the funnel type cone lens is produced and processed through a mould production and injection molding technology, has the advantage of simple production process, and ensures that the precision of a cone surface is high and stable; the same material is used to carry out injection molding on the aspheric part and the cone lens part in the component; after gluing, the problem that the precision is decreased as time goes on and an environment changes due to different material expansion coefficients is avoided; and the laser projection line cone type optical component has the advantages of simple process, low processing cost and high precision and yield.
Description
Technical field
The utility model relates to optical module, particularly the optical module in a kind of laser leveler or laser level.
Background technology
In the prior art, the structure of the optical module in laser leveler or laser level, is that non-sphere collimation mirror sheet is injected to lens barrel, and circular cone aluminum component is glued on footstock, and between lens barrel and footstock, with 4 support lenses support and connection, support portion is bonding with glue.Due to the lens barrel of this product and the connection of footstock use support lenses and glue, in addition the volume of support lenses can not be excessive and can not be replaced with other opaque material, (because the effect of support lenses is that lens barrel and footstock are coupled together, to meet the condition that can not stop that laser passes through) simultaneously, there is following shortcoming: one, the limitation of connected mode, cause such strength of joint deficiency, precision is low; Two, the difference of connector material, the expansion coefficient difference of each material, along with the increase of service time, precision reduces gradually.Three, the processing cost of circular cone aluminum component is very expensive; Four, assembling procedure complexity, difficulty is large, and yields is low.
Utility model content
In order to overcome the defect of prior art, the utility model provides a kind of laser demarcation pyramid type optical module, and this optical module service precision is high, and production process is simple, and yields is high.
Technical solutions of the utility model are: a kind of laser demarcation pyramid type optical module, comprise lens barrel and aspherical lens, described aspherical lens is positioned at lens barrel, and described lens barrel top is also provided with funneling circular cone eyeglass, and described lens barrel and aspherical lens are made integral molding structure.
Its advantage is that funneling circular cone eyeglass passes through to make the production and processing of mold injection technology, and production process is simple, has guaranteed that the precision of circular conical surface is high and stable; Aspheric surface part in its sub-assembly and axicon lens part are used same material injection moulding, after gummed, can, because of material expansion coefficient difference, with service time passing and environmental change, not cause precision to reduce.
The utility model further improves and is: described funneling circular cone eyeglass is boss type, and its top center offers the pyramid type pit of opening upwards.
The utility model further improves and is: described lens barrel is socketed on funneling circular cone eyeglass bottom, and both are adhesively fixed.
The utility model further improves and is: the optical plane place that enters at described funneling circular cone eyeglass is provided with aperture thin slice.
Its advantage is to control light inlet amount.
The utility model further improves and is: described aperture thin slice in the form of a ring, is fixed on entering on optical plane of funneling circular cone eyeglass by bonding mode.
The utility model further improves and is: described lens barrel and aspherical lens and funneling circular cone eyeglass are transparent plastic material.
The beneficial effects of the utility model are: the funneling circular cone eyeglass in the utility model is by making the production and processing of mold injection technology, production process is simple, the precision that guaranteed circular conical surface high and stable (angle precision can be controlled at 15 " in, cause laser to be controlled in 2MM in the lateral error at 10M place); Aspheric surface part in its sub-assembly and axicon lens part are used same material injection moulding, after gummed, can, because of material expansion coefficient difference, with service time passing and environmental change, not cause precision to reduce.Technique is simple, and processing cost is low, and precision and yields are high.
