example 1

[0044] refer to figure 1 , the present invention provides a high-precision laser cleaning and cleaning quality online monitoring device, which is characterized in that it includes an XY axis platform, a laser cleaning head, a resistance probe array, a resistance measuring instrument, a probe height self-adaptive adjustment unit and a workstation,

[0045] The laser cleaning head includes a laser head, a vibrating mirror, and a field mirror. During laser cleaning, the laser beam is emitted from the laser head, passes through the vibrating mirror and the field mirror in turn, and irradiates the surface of the cleaning workpiece placed on the XY axis platform. The XY-axis platform moves to clean the surface of the workpiece to complete the surface cleaning of the entire workpiece;

[0046] The resistance probe array includes a probe array of a specific shape formed by a plurality of resistance measuring probes, which is one of square, rectangular or circular probe arrays; the res...

example 2

[0064] The difference between this embodiment and Example 1 is that the resistance measurement accuracy measured by the resistance meter is 0.001 milliohms, which is relatively high, and can greatly reduce the impact of the laser cleaning laser environment such as light and noise on the monitoring system. For different environments More adaptable.

[0065] In this embodiment, a square resistance probe array of 5 cm*5 cm is selected.

[0066] The rest of the content is the same as Example 1.

example 3

[0068] The difference between this embodiment and Example 1 is that the workstation uses the axis control control module and the probe height self-adaptive adjustment control module to collect and clean the workpiece surface position information (coordinates) and the corresponding probe height distribution values ​​in real time. The height distribution value is filtered by a first-order filter to reduce measurement errors.

[0069] In this embodiment, a square resistance probe array of 10 cm*10 cm is selected. The resistance measurement accuracy measured by the resistance meter is specifically selected as 0.001 milliohms.

[0070] The rest of the content is the same as Example 1.

Abstract

The invention discloses a high-precision laser cleaning and cleaning quality online monitoring device. The device comprises an XY-axis platform, a laser cleaning head, a resistance probe array, a resistance measuring instrument, a probe height self-adaptive adjusting unit and a workstation. According to the high-precision laser cleaning and cleaning quality online monitoring device and method, thecleaning condition of each part on a workpiece to be cleaned is detected, so that the real-time detection result is less affected by the environment, the measurement accuracy is high, the position with poor cleaning effect is accurately positioned, and the cleaning effect is ensured.

Description

technical field [0001] The invention relates to the field of laser cleaning and cleaning quality monitoring, in particular to a device and method for high-precision laser cleaning and online monitoring of cleaning quality. Background technique [0002] Laser cleaning is a process in which laser radiation is used to irradiate the surface of the workpiece, so that the pollutants and rust on the surface absorb laser energy and produce instant peeling or evaporation changes, and are finally effectively removed from the substrate. It is a green and efficient cleaning method. , has gradually been accepted by the public in industrial production and daily life applications, among which laser cleaning technology is used in the fields of molds, national defense weapons and equipment, aircraft waste skin paint, building exterior walls, precision instruments, electronics industry, nuclear reactor pipes and historical relics. All have been greatly developed. It has the advantages of env...
