Background
When the lens of the vibrating mirror motor is assembled, the smaller the front surface of the lens, namely the included angle between the A surface in fig. 6 and the axis of the motor rotating shaft, namely the value of the angle R in the diagram, the higher the installation precision of the lens is, and the closer the reflection light path is to the theoretical calculation value.
The former installation correction method is that firstly, a lens is stuck on a lens clamp to form a lens assembly, then the lens assembly is locked to the upper end of a motor shaft through the lens clamp, finally, red light reflection light path detection is adopted, and the error is controlled within a range.
In actual operation, due to the bonding error of the clamp and the lens, the tolerance of the clamp hole and the motor shaft, and the like, the tolerance of the included angle between the lens and the motor shaft is not controllable, the assembly is generally repeated for a plurality of times, red light detection is carried out after each assembly, the situation that the tolerance meets the requirement range is likely to occur, the assembly efficiency is low, and the error value cannot directly reflect the assembly precision.
The red light correction method has low accuracy of test results, cannot accurately define an error range, repeatedly locks the test, consumes long time in the correction process, and cannot control the correction results.
However, due to the limitation of the current manufacturing process of the galvanometer motor, the influence of multiple factors such as the processing error of the lens clamp, the manufacturing error of the motor shaft end and the like, when the lens and the lens clamp are adhered, the reference coincidence between the lens reference surface and the lens clamp installation matching shaft hole reference cannot be completely ensured. When the bonded lens assembly is mounted on the motor shaft end, the superposition of the lens reference surface and the motor shaft center surface cannot be ensured.
In order to solve the problem of lens installation accuracy, some schemes are also adopted in the prior art to ensure the bonding quality of the lens, for example, patent document with the authorized publication number CN216387530U provides a vibrating lens installation fixture, which comprises: the limiting fixing ring is sleeved on the shaft sleeve of the motor shaft and used for positioning the position of the motor shaft. The upper side of the limiting fixing ring is symmetrically provided with two mounting plates along the central axis of the limiting fixing ring, and the central positions of the opposite faces of the two mounting plates are provided with vertical mounting grooves along the central axis direction, wherein the mounting grooves are used for mounting lenses. The mounting tool is simple in structure, low in manufacturing cost, convenient to use and operate, capable of rapidly mounting lenses, high in mounting precision and greatly reduced in production cost.

The mounting device for the reflecting mirror provided by the scheme can relieve the technical problems of the prior art that the mounting of the reflecting mirror in the laser galvanometer is difficult to achieve high mounting precision and the mounting process is complicated.
However, the scheme is of a direct bonding lens structure, the bonding quality precision is determined by the machining and assembling precision of the fixture, the angle error of the lens cannot be displayed in real time, the angle error cannot be adjusted in real time, and the scheme is not suitable for a structure in which the lens and the lens clamp are bonded.
