Abstract
The present invention provides a laser demarcation tetragonal pyramid-shaped optical component, which comprises a lens barrel, an aspheric lens, an aperture thin sheet and a funnel type tetragonal pyramid lens, wherein the aperture thin sheet is pasted on the bottom plane of the funnel type cone mirror, the aspheric lens is positioned in the lens barrel, the upper portion of the lens barrel is further provided with the funnel type tetragonal pyramid lens, and the lens barrel and the aspheric lens form the integrated forming structure. According to the present invention, the funnel type tetragonal pyramid lens is produced and processed through the mold production injection molding technology, such that the production process is simple, and the high and stable precision of the conical surface of the tetragonal pyramid is ensured; the aspheric part and the tetragonal pyramid lens part in the components are subjected to the injection molding by using the same materials, such that the problem that the different material expansion coefficients can cause precision reducing along with the use time lapse and the environment change can not be produced after the gluing; and the advantages of simple process, low processing cost, high precision and high yield are provided.
Description
Technical field
The present invention relates to optical module, the optical module particularly 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, that non-sphere collimation mirror sheet is injected lens barrel, circular cone aluminum component is glued on footstock, with 4 support support and connection between lens barrel and footstock, support portion glue is bonding, and laser generates the five orthogonal level of bundle and plummet laser after optical module.There is following shortcoming: one, the angle precision of the four face cone aluminum component work in-process conical surfaces and conical surface angle precision each other are very difficult to ensure card, 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.
Summary of the invention
In order to overcome the defect of prior art, the invention provides the tapered optical module in a kind of laser demarcation four directions, this optical module service precision is high, and production process is simple, and yields is high.
Technical solution of the present invention is: 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 make 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, ensure that the precision of circular conical surface is high and stable; Aspheric component and axicon lens part use same material injection moulding, can not be different because of material expansion coefficient after gummed, cause precision to reduce with passing service time and environmental change.
The present invention 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 present invention further improves and is: described lens barrel is socketed on funneling tetragonal pyramid eyeglass bottom, and both is adhesively fixed.
The present invention further improves and is: the optical plane place that enters of described funneling tetragonal pyramid eyeglass is provided with aperture thin slice.
Its advantage to control light inlet amount.
The present invention further improves and is: described aperture thin slice in the form of a ring, is fixed on entering on optical plane of funneling tetragonal pyramid eyeglass by bonding mode.
Further improvement of the present invention is: described lens barrel and aspherical lens and funneling tetragonal pyramid eyeglass are transparent plastic material.
The invention has the beneficial effects as follows: the funneling tetragonal pyramid eyeglass in the present invention is by making the production and processing of mold injection technology, production process is simple, ensure that the precision of circular conical surface high and stable (angle precision can control 15 " within, cause laser to control within 2MM in the lateral error at 10M place); Aspheric component in its sub-assembly and axicon lens part use same material injection moulding, can not be different because of material expansion coefficient after gummed, cause precision to reduce with passing service time and environmental change.Technique is simple, and processing cost is low, precision and yields high.
