Description

Technical Field

[0001] The invention belongs to the technical field of laser processing equipment, and in particular relates to a laser galvanometer for coaxial visual positioning, distance measurement and temperature measurement, and also relates to a galvanometer processing method of the laser galvanometer. Background Art

[0002] Laser galvanometer marking is currently widely used, but the traditional marking galvanometer has no visual assistance and is in a blind marking state. If the marked product needs to be positioned, a rangefinder CCD is generally used to determine the position. The disadvantages of this positioning are slow speed and poor imaging quality. Especially for applications with high processing precision, traditional galvanometers and rangefinder CCDs are very difficult and complex to implement.

[0003] When using traditional galvanometer processing, if there is a height difference in the processing object and the height of the galvanometer needs to be changed to adapt to the working distance of the field lens, it is generally necessary to manually measure the height difference of the workpiece and then manually rotate the lead screw to achieve it. This step must be repeated each time a different workpiece is changed. The operation is complicated and the positioning is inaccurate due to the influence of manual intervention. When encountering relatively complex processing workpieces, this operation will be very cumbersome and the processing accuracy is difficult to guarantee.

[0004] When processing some special objects that are sensitive to temperature, traditional laser galvanometers usually make advance estimates, conduct repeated tests on different power devices, and preset processing parameters such as applicable laser power, processing time, and processing frequency to determine the implementation plan. It also relies on manual intervention to achieve temperature matching, which is a cumbersome process and requires high standards from workers. With the influence of time, working conditions and other factors, the temperature change value cannot be fed back to the processing system in a timely manner, and the processing quality is difficult to guarantee. Summary of the invention

[0007] The present invention is also characterized in that: The side wall of the galvanometer housing is connected with a motor control connector, which is connected with the galvanometer drive unit. The side wall of the galvanometer housing is also connected with a visual ranging connector, which is electrically connected with the visual positioning and ranging module.

[0009] Each connecting plate is connected to a temperature measuring probe, which is arranged close to the edge of the connecting plate. The connecting plate is also connected to a temperature measuring connector, which is electrically connected to the temperature measuring probe.

[0010] The galvanometer drive unit includes a galvanometer drive board, which is connected to the inner wall of the galvanometer housing. The board surface of the galvanometer drive board is connected to a connector, which is electrically connected to the motor control connector, and the connector is electrically connected to the galvanometer motor unit.

[0011] The galvanometer motor unit includes a first galvanometer motor, which is connected to the inner wall of the galvanometer housing, and is connected to a first lens. The first lens is arranged close to the light inlet. The inner wall of the galvanometer housing is also connected to a second galvanometer motor, and is connected to a second lens. The second lens is arranged opposite to the first lens. The second lens can highly reflect the corresponding laser wavelength and has the function of highly transmitting other wavelengths. The first galvanometer motor and the second galvanometer motor are both electrically connected to the connector of the galvanometer drive board.

[0012] The second galvanometer motor is vertically arranged to the inner wall of the galvanometer housing connected thereto, and the angle between the first galvanometer motor and the inner wall of the galvanometer housing connected thereto is set to 20° to 70°.

[0013] The visual positioning and ranging module includes a camera, which is connected to the inner top surface of the galvanometer housing through a connecting flange. The flange is connected to a rangefinder. The lenses of the rangefinder and the camera are both arranged directly above the field mirror. The rangefinder and the camera are both electrically connected to the visual ranging connector.

[0014] Another technical solution adopted by the present invention is a galvanometer processing method of a laser galvanometer for coaxial visual positioning, distance measurement, and temperature measurement, which is specifically implemented according to the following steps: Step 1: The laser enters from the light inlet, is reflected by the first lens and reaches the second lens, and then is reflected by the second lens and transmitted by the field lens and focused to the working surface; Step 2: Turn on the fill light and the temperature probe, and use the temperature probe to monitor the temperature near the working surface; Step 3: The light from the fill light is transmitted through the field lens and the second lens to reach the camera lens, completing the visual positioning, and the rangefinder performs distance measurement.
