Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of galvanometer lens process equipment, in particular to a galvanometer lens mounting and correcting device and method. BACKGROUND

[0002] When the galvanometer lens is assembled, the front surface of the lens, i.e. Figure 6 The smaller the angle R between the middle A surface and the motor shaft axis, the higher the mounting precision of the lens, and the closer the reflected light path to the theoretical calculation value.

[0003] The previous mounting and correcting method is to first paste the lens on the lens holder to form a lens assembly, then lock the lens assembly on the upper end of the motor shaft through the lens holder, and finally detect the error by red light reflection, with the error controlled within a certain range.

[0004] In actual operation, due to the bonding error between the holder and the lens, the tolerance of the holder hole and the motor shaft, etc., the angle tolerance between the assembled lens and the motor shaft axis cannot be controlled, and generally needs to be assembled repeatedly, and red light detection is performed after each assembly, which may result in a situation that the tolerance is within the required range, the assembly efficiency is low, and the error value cannot directly reflect the assembly precision.

[0005] The red light correction method has low test result precision, cannot accurately define the error range, requires repeated locking and testing, the correction process is time-consuming, and the correction result is uncontrollable.

[0006] However, due to the limitations of the current galvanometer lens manufacturing process, as well as the lens holder processing error, motor shaft end manufacturing error and other factors, when the lens and the lens holder are bonded, it cannot be fully guaranteed that the lens reference surface and the lens holder mounting and fitting shaft hole reference are coincident. When the bonded lens assembly is mounted on the motor shaft end, it cannot be guaranteed that the lens reference surface and the motor shaft center surface are coincident.

[0007] In order to solve the problem of lens mounting precision, the prior art also adopts some schemes to ensure the quality of lens bonding, such as the patent document with the authorized announcement number CN216387530U provides a mirror lens mounting tool, which includes: a limiting fixed ring, which is sleeved on the shaft sleeve of the motor shaft, used for positioning the position of the motor shaft. Two mounting plates are symmetrically arranged on the upper side of the limiting fixed ring along the center axis of the limiting fixed ring, and the center positions of the opposite surfaces of the two mounting plates have vertical mounting grooves along the center axis direction, which are used for mounting the lens. The mounting tool has simple structure, low manufacturing cost, convenient operation, can quickly realize the installation of the lens, and has high installation precision, which greatly reduces the production cost. The patent document with the application publication number CN108549141A provides a mounting device for a reflecting lens, which includes: a positioning plate, a bracket connecting mechanism and a lens locking mechanism; the positioning plate is provided with a positioning structure, which cooperates with the reflecting lens to be installed; the bracket connecting mechanism is used for installing the lens bracket, and the reflecting lens and the lens bracket can rotate relative to the positioning plate around the first axis; the bracket connecting mechanism can translate relative to the positioning plate along the second axis; the first axis is perpendicular to the second axis; the lens locking mechanism is used for locking the reflecting lens to the positioning structure. Through the reflecting lens mounting device provided by the scheme, the technical problems of the prior art that the installation of the reflecting lens in the laser vibrating mirror is difficult to achieve high installation precision and the installation process is complicated can be solved.

[0008] However, such schemes are all directly bonded with lens structures, and the bonding precision is determined by the machining and assembly precision of the tooling, the lens angle error cannot be displayed in real time, the angle error cannot be adjusted in real time, and the scheme cannot be applied to the structure of the lens and the lens clip which have been bonded.

The lens clamp 42 is pre-installed on the galvanometer motor 5 through the lens clamping locking screw 9 with an adjustment gap. The galvanometer lens mounting and correcting device of the embodiment includes a base 8, a sliding lock assembly, a sliding lock assembly, a multi-point laser range finder 3, and a correction reference plane parallel to the XZ axis plane. The sliding lock assembly and the multi-point laser range finder 3 can be directly or indirectly mounted on the base 8. In this embodiment, the sliding lock assembly is mounted on the base 8 through a support plate, and the multi-point laser range finder 3 is mounted on the base 8 through a range finder fixing plate 83 and a range finder sliding block guide rail group.

The present embodiment uses a tension spring, which can eliminate the gap at the front end of the bearing and leave the gap at the rear end.

[0050] In order to not separately set a separate multi-point laser range finder 3 correction reference surface, the present embodiment uses the front end surface 231 of the motor positioning block 23 as the correction reference surface for self-checking and correction of the multi-point laser range finder 3. That is, the front end surface 231 of the motor positioning block 23 becomes a standard plane formed by the XZ axis, which is roughly parallel to the front surface of the lens 41.

[0051] In order to realize the switching between the position of the multi-point laser range finder 3 on the correction reference surface and the position of the lens 41, the present embodiment horizontally installs a range finder guide rail 81 on the base 8 below the multi-point laser range finder 3.
