Description

Technical Field

[0001] This utility model relates to the field of laser galvanometer scanning measurement and monitoring technology, and in particular to an infrared vertical laser coaxial measurement and monitoring device. Background Technology

[0002] Laser galvanometer scanning is widely used in laser marking, digital processing, 3D scanning and other fields. As an excellent vector scanning device, the accuracy of the laser galvanometer's repeatability directly determines the performance of the system.

[0003] However, laser galvanometers may experience positioning inaccuracies during use, leading to repetitive positioning deviations that affect the positioning of the laser beam. Therefore, it is necessary to measure the repetitive positioning accuracy of the laser galvanometer.

[0004] In existing laser galvanometer scanning processes, the laser galvanometer scanning system and the monitoring system are set up separately. The position change of the light spot projected by the laser galvanometer is captured from a distance, thereby indirectly detecting the repeatability accuracy of the laser galvanometer. However, this method cannot synchronously monitor the workpiece with the laser galvanometer scanning system, and there will be visual deviations in measuring the processing dimension accuracy and displaying the processing progress. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model designs an infrared vertical laser coaxial measurement and monitoring device.

[0006] The present invention adopts the following technical solution:

[0007] An infrared vertical laser coaxial measurement and monitoring device includes a scanning frame with an illumination lamp below it. A scanning window is provided on the scanning frame, and a workpiece is placed below the scanning window. A scanning galvanometer and a beam splitter are fixedly mounted on the scanning frame. The scanning galvanometer is connected to and has a beam expander installed on it. The beam expander is connected to and has a laser installed on it. The beam splitter is mounted directly above the scanning window and corresponds to the scanning galvanometer. A monitoring camera is fixedly mounted on the scanning frame via an adjustment plate. The monitoring lens of the monitoring camera is positioned corresponding to the beam splitter. The adjustment plate is used to adjust the position of the monitoring lens of the monitoring camera relative to the beam splitter.

[0008] The laser beam is expanded and scanned, then reflected again by a beam splitter, and processed vertically on the workpiece. The position of the monitoring camera's lens is adjusted so that the light reflected from the workpiece is transmitted through the illumination beam via the beam splitter, and then received and imaged by the monitoring lens and camera. When used for laser galvanometer scanning processing, the scanner moves, and the monitoring camera's lens moves synchronously to perform synchronous visual imaging monitoring of the workpiece, measure the processing dimensional accuracy in real time, and display the processing progress.

[0009] Preferably, the adjustment plate is provided with a lifting adjustment device, which can be used to adjust the position of the monitoring lens of the monitoring camera relative to the beam splitter.

[0010] Preferably, the scanning galvanometer and beam splitter are detachably mounted to the scanning frame via a mounting bracket.

[0011] Preferably, the lighting lamps are installed on both sides below the scanning window of the scanning frame.

[0012] Preferably, a protective plate is provided on the outside of the scanning frame to prevent accidents caused by laser outflow.

[0013] The beneficial effects of this utility model are: when this utility model is used for laser galvanometer scanning processing, the scanning machine moves and the monitoring lens of the monitoring camera moves synchronously to perform synchronous visual imaging monitoring of the processed workpiece, measure the processing dimension accuracy in real time and display the processing progress, and realize infrared vertical laser coaxial measurement and monitoring.
