Abstract
The utility model provides a laser demarcation tetragonal-pyramidal optical module. The laser demarcation tetragonal-pyramidal optical module comprises a lens cone, an aspherical lens, an aperture thin sheet and a funnel type tetragonal-pyramidal mirror, wherein the aperture thin sheet is adhered onto a bottom plane of the funnel type tetragonal-pyramidal mirror; the aspherical lens is positioned in the lens cone; a funnel type tetragonal-pyramidal lens is also mounted on the upper part of the lens cone; the lens cone and the aspherical lens are of an integral structures. The funnel type tetragonal-pyramidal lens is produced and processed by an injection-molding technology for manufacturing a mould; the manufacture process is simple, so that high and stable precision of conical surfaces of the tetragonal pyramid is ensured; secondly, an aspherical part and a conical lens part in the module are manufactured by injection molding of same materials, so that after gluing, the precession is not reduced along with time lapse and environment change since the expansion coefficients of the materials are not different. The laser demarcation tetragonal-pyramidal optical module is simple in process, low in processing cost and high in precision and yield.

Background technology
In the prior art, the structure of the optical module in laser leveler or laser level, that non-sphere collimation mirror sheet is injected to lens barrel, circular cone aluminum component is glued on footstock, between lens barrel and footstock, by 4 stent support, connect, support portion is bonding with glue, and laser generates the orthogonal level of five bundles and plummet laser after optical module.There is following shortcoming: angle precision and the conical surface angle precision each other of one, boring the aluminum component work in-process conical surface are on four sides difficult to ensure card very much, and consistance is poor.Two, the difference of connector material, the expansion coefficient of each material is different, and 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 is complicated, and 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 four directions tapered 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: the tapered optical module in a kind of laser demarcation four directions, comprise lens barrel and aspherical lens, described aspherical lens is positioned at lens barrel, and described lens barrel top is also provided with funneling tetragonal pyramid eyeglass, and described lens barrel and aspherical lens are made integral molding structure.
Its advantage is that funneling tetragonal pyramid 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 and axicon lens are partly used same material injection moulding, can be different because of material expansion coefficient after gummed, and with service time passing and environmental change, cause precision to reduce.
The utility model further improves and is: described funneling tetragonal pyramid eyeglass is boss type, and its top center offers the tetragonal pyramid bench-type pit of opening upwards.
The utility model further improves and is: described lens barrel is socketed on funneling tetragonal pyramid eyeglass bottom, and both are adhesively fixed.
