Problems solved by technology

It can be understood that if the laser head has a certain angle in the width direction of the marking line, it will have different effects on each part of the marking line in the width direction of the marking line. Based on the short board principle, it will affect the overall efficiency.

Embodiment Construction

[0027] In the mechanical field, it can be understood that the direction in which the chassis moves based on its normal direction of travel is the front, and the opposite direction is the rear. The direction consistent with the front-rear direction is the longitudinal direction, and the direction perpendicular to the longitudinal direction in the horizontal plane is the horizontal or left-right direction.

[0028] The laser used for laser cleaning is not involved in the Chinese patent document CN208023375U. After more experiments, it is determined that the pulsed Nd-YAG laser has the best effect. The wavelength of the laser emitted by this laser is 1064nm, which belongs to the near-infrared band. Correspondingly, lasers with other wavelengths in the near-infrared band also have better effects than lasers with other wavelengths.

[0029] The principle of laser cleaning is that when the paint film absorbs the laser and is heated alternately, it emits sound waves to the surroundin...

Abstract

The invention discloses a laser cleaning device for a marker line of a sports field. The laser cleaning device comprises a chassis, a laser device, a dust collector, a photoelectric sensor group and apower cabin, wherein a main body of the laser device is mounted on the chassis, and a laser head of the laser device is fixedly mounted in a first assembly hole in the chassis, so that the laser headfaces downward; a dust storage box of the dust collector is mounted on the chassis, and a dust collecting port is formed transversely in the bottom of a carrier plate through a second assembly hole located in the chassis; the photoelectric sensor group is arranged transversely at the front end of the chassis and tracks the marker line based on reflection; and the power cabin is mounted on the carrier plate, the power cabin is provided with a controller, and the controller is connected to the photoelectric sensor group and outputs a driving mechanism connected to the chassis, and the driving mechanism drives the chassis to track the line according to the boundary of the marker line determined by the photoelectric sensor group based on reflection. The laser cleaning device provided by the invention is relatively high in degree of automation, so that the laser cleaning device can clean the sports field continuously.

Description

technical field [0001] The invention relates to a laser cleaning device for marking lines of sports venues, and belongs to the technical field of laser cleaning. Background technique [0002] Sports field marking lines are widely used, such as track and field track marking lines, basketball, football field marking lines, etc. After a long period of impact and wear on the soles of athletes, the marking lines are bound to be worn or naturally corroded. will drop, affecting its visibility. Therefore, in order to ensure that the audience can better watch the game and the players can be more clearly identified, the marking lines will be cleaned and reset every once in a while. [0003] The traditional marking line removal methods mainly include grinding removal method and high-pressure water jet removal method. Among them, the grinding removal method is to use the blade to fully contact and polish the marking line to achieve the purpose of removing the marking line. Its efficie...
