Problems solved by technology

[0005] Therefore, in view of the above-mentioned technical shortcomings, the present invention has made significant improvements to the original technology through ingenious ideas. The present invention proposes a three-dimensional laser scanning head, designs a planetary gear transmission group, improves the structure, and truly realizes the vertical rotation direction and The independent movement of the horizontal rotation direction simplifies the control of the transmission system, facilitates the operation, improves the movement precision, and overcomes the problem of mistakes caused by inconvenient operation and control in the scheme with the background technology; in addition, the present invention is also provided with a zoom system , the functions that can be realized by the scanning head are increased, and the laser distance sensor is also set to improve the accuracy of the whole system. The full reflection mirror with a larger mirror area can expand the scanning range, and avoid the problem of the transmission system's strength reduction due to the opening of the light hole.

Abstract

The invention discloses a three-dimensional laser scanning head, and the scanning head comprises an optical path assembly and a drive assembly, wherein the drive assembly includes a planetary gear transmission group, and the optical path assembly comprises a semi-transmission and semi-reflection mirror, a total reflection mirror group and a field lens. The drive assembly can be set at one end of the field lens, thereby enabling the drive assembly to be disposed between the semi-transmission and semi-reflection mirror and the field lens. The drive assembly can be set at the other end of the field lens, thereby enabling the field lens to be disposed between the semi-transmission and semi-reflection mirror and the drive assembly. In addition, several schemes which meet the different scanningdemands are designed for the total reflection mirror group. The scanning head is provided with the planetary gear transmission group, thereby achieving the independent movement in the rotation direction, and simplifying the control of a transmission system. The scanning head is convenient to operate, and improves the movement precision. The invention also provides the other structural layout, thereby enabling the total reflection mirror group to employ a total reflector with the increased mirror surface area so as to enlarge the scanning range. In addition, a variable focal length system and alaser range-finding system are added, thereby enabling the scanning head to have corresponding functions.

Description

technical field [0001] The invention relates to the technical field of laser scanning equipment, in particular to a three-dimensional laser scanning head. Background technique [0002] The existing scanning head adopts the dual vibrating mirror method, that is, one vibrating mirror rotates around the horizontal axis and the other vibrating mirror rotates around the vertical axis without intersecting space. The superimposition of the two vibrating mirrors realizes scanning within a certain area. It is determined by the size of the lens, and the zoom is realized by the field lens. To realize a wide range of scanning, it is necessary to increase the size of the vibrating mirror, that is, the mass of the vibrating mirror is increased, and the required space is increased. A large burden leads to the inability to improve the accuracy and speed of the galvanometer movement, resulting in the inability to improve the scanning accuracy and speed, and it is difficult to expand the scan...
