Description

Technical Field

[0001] The utility model relates to the technical field of laser calibration equipment, in particular to a laser light path parallel calibration device. Background Art

[0002] Laser processing technology is widely used in aerospace, military, and industrial manufacturing fields. Laser processing equipment is widely used in the field of mechanical processing because of its advantages such as fast processing speed, large processing size range, and a wide range of processable materials. The laser processing module is the core component of the laser processing equipment, which is mainly composed of a galvanometer, a laser generator, a motor, etc. The laser generator provides laser energy to the galvanometer. The galvanometer is connected to the output shaft of the motor through the seat, and the galvanometer is driven by the motor to rotate so that the galvanometer can perform laser processing on the workpiece. If the galvanometer is installed on the seat and there is a skew, the light path emitted by the galvanometer will not be on the same plane when the motor drives the galvanometer to rotate, resulting in inaccurate processing points, which will seriously affect the processing accuracy of the product. However, there is no device on the market specifically for calibrating the parallelism of the laser light path of the laser processing module. It can only be calibrated manually. The calibration process is relatively cumbersome and the accuracy is insufficient, which restricts the effective implementation of the laser light path calibration work. Summary of the invention

[0003] The problem to be solved by the utility model is to provide a laser light path parallel calibration device, which can realize automatic calibration of the laser light path and improve the calibration accuracy.

[0004] To solve the above technical problems, a laser optical path parallel calibration device provided by the utility model is required, which is used to calibrate the optical path of a laser processing module. The laser processing module includes a first transverse rotating motor, a galvanometer mounting seat driven by the first transverse rotating motor, and a galvanometer mounted on the galvanometer mounting seat, and includes a calibration mechanism and a laser module clamping mechanism. The calibration mechanism includes a base, a Y-axis linear drive mechanism arranged on the top of the base, an X-axis linear drive mechanism driven by the Y-axis linear drive mechanism, a longitudinal rotating motor driven by the X-axis linear drive mechanism, a clamp driven by the longitudinal rotating motor, a mounting seat clamped on the clamp, a second transverse rotating motor fixedly connected to the mounting seat, a longitudinal swing arm driven by the second transverse rotating motor, and a dot detection plate detachably connected to one end of the longitudinal swing arm; the laser module clamping mechanism includes a stand arranged on one side of the top of the base, a Z-axis linear drive mechanism arranged on the stand, and a laser module mounting seat driven by the Z-axis linear drive mechanism, and the first transverse rotating motor is detachably connected to the laser module mounting seat.

[0005] Preferably, the Y-axis linear drive mechanism includes a Y-axis slide connected to the top of the base in a sliding manner along the Y-axis direction, and a Y-axis linear module arranged on the top of the base and drivingly connected to the Y-axis slide; the X-axis linear drive mechanism includes an X-axis slide connected to the top of the Y-axis slide in a sliding manner along the X-axis direction, and an X-axis linear module arranged on the top of the Y-axis slide and drivingly connected to the X-axis slide, and a longitudinal rotation motor is arranged on the X-axis slide; the Z-axis linear drive mechanism includes a Z-axis slide connected to the stand in a sliding manner along the Z-axis direction, and a Z-axis linear module arranged on the stand and drivingly connected to the Z-axis slide, and a laser module mounting seat is arranged on the Z-axis slide.

[0006] The beneficial effects of the utility model are as follows: the utility model provides a laser optical path parallel calibration device, and the first transverse rotating motor of the laser processing module is installed on the laser module mounting seat, that is, the laser processing module can be installed on the Z-axis linear driving mechanism, and the laser processing module can be driven to move up and down through the Z-axis linear driving mechanism, and the dot detection plate can be driven to move forward and backward through the Y-axis linear driving mechanism, and the dot detection plate can be driven to move left and right through the X-axis linear driving mechanism, and the dot detection plate can be driven to rotate through the longitudinal rotating motor, and the longitudinal swing arm can be driven to swing longitudinally through the second transverse rotating motor. The dot detection plate can be first placed at the 12 o'clock position, and the galvanometer mounting seat can be driven to rotate through the first transverse rotating motor so that the output end of the galvanometer is facing the dot detection plate. The galvanometer is allowed to perform the first laser dot on the dot detection board, and then the longitudinal swing arm is driven by the longitudinal rotation motor to swing 180° so that the dot detection board is located at the 6 o'clock position, and the galvanometer mounting seat is driven by the first transverse rotation motor to rotate 180° so that the output end of the galvanometer is facing the dot detection board again, and the galvanometer can perform the second laser dot on the dot detection board. The dot surface on the dot detection board can be observed with the help of a magnifying glass. If there is only one processing point on the dot surface on the dot detection board, it means that the two laser dots are hit at the same position, indicating that the installation of the galvanometer is not skewed. If there are two processing points on the dot surface on the dot detection board, it means that the two laser dots are hit at different positions, indicating that the installation of the galvanometer is skewed. It has a simple structure and can automatically complete the calibration operation of the parallelism of the laser optical path, simplify the operation process, and improve the calibration accuracy.

A clamp 24 driven and connected to the longitudinal rotating motor 23, a mounting base 25 clamped on the clamp 24, a second transverse rotating motor 26 fixedly connected to the mounting base 25, a longitudinal swing arm 27 driven and connected to the second transverse rotating motor 26, and a dot detection plate 28 detachably connected to one end of the longitudinal swing arm 27; the laser module clamping mechanism 3 includes a stand 30 arranged on one side of the top of the base 20, a Z-axis linear drive mechanism 31 arranged on the stand 30, and a laser module mounting base 32 driven and connected to the Z-axis linear drive mechanism 31, and the first transverse rotating motor 10 is detachably connected to the laser module mounting base 32.

[0014] Its working principle is that the first transverse rotating motor 10 of the laser processing module 1 is installed on the laser module mounting seat 32, and the laser processing module 1 can be installed on the Z-axis linear driving mechanism 31. The Z-axis linear driving mechanism 31 can drive the laser processing module 1 to move up and down, the Y-axis linear driving mechanism 21 can drive the dot detection plate 28 to move forward and backward, and the X-axis linear driving mechanism 22 can drive the dot detection plate 28 to move left and right.

The dot surface on the dot detection plate 28 can be observed with the help of a magnifying glass. If there is only one processing point on the dot surface on the dot detection plate 28, it means that the two laser dots are hit at the same position, which means that the installation of the galvanometer 12 is not skewed.
