Description

Automatic window cleaning equipment

Technical Field

The utility model relates to a glass cleaning device field, concretely relates to automatic window cleaning equipment.

Background

The traditional window cleaning robot mainly adsorbs a machine body on glass by an active vacuum sucker or a magnetic device at the bottom of the robot. The purpose of walking on the glass according to a preset route is realized by using automatic control parts such as a sensor, a walking mechanism, a steering mechanism, a control module and the like. Generally, a window cleaning robot which depends on a vacuum chuck for adsorption has higher requirements on factors such as flatness and smoothness of glass, and a robot which depends on a magnetic device for adsorption has lower requirements on the surface of an adsorption medium.

In the prior art, a window cleaning robot is generally required to integrate an adsorption mechanism, a walking mechanism, a power supply, a scrubbing mechanism, a sensor, a circuit board and other parts, and some wet window cleaning robots also integrate a liquid storage device, a scrubbing plate, a scraping plate and other parts, which causes the self weight of the window cleaning robot to be very high. The window cleaning robot with high self weight generally has a risk of falling off after being adsorbed on glass.

In order to solve the problem that the window cleaning robot accidentally falls off, CN108354505A provides a scheme for preventing the window cleaning robot from falling off, which comprises a window to be cleaned, a driving brush, a driven brush and an anti-slip device, wherein the driving brush is adsorbed on the surface of the window to be cleaned, the driven brush is adsorbed on the other side surface of the window to be cleaned, the anti-slip device bypasses the outer edge of the window to be cleaned and is connected with the driving brush and the driven brush, the anti-slip device comprises a rope barrel, a safety rope, a driving brush safety hook and a driven brush safety hook, the safety rope is wound in the rope barrel, the driving brush safety hook is installed at one end of the safety rope, and the driven brush safety hook is installed at the other end of the safety rope.

firstly, the rope drum takes up a certain space, which also puts requirements on the window beside the window to be wiped, which must allow the rope drum to be placed, and the rope drum has a certain volume. Currently, only some windows are able to meet their requirements.

And secondly, even if the safety rope exists, a certain safety measure is provided for the window machine to fall accidentally, so that the window machine is prevented from falling. But can't solve the problem of falling of window machine fundamentally, even if there is the existence of safety rope, also can cause the impact to the window machine when the window machine falls to also can influence the efficiency of wiping the window.

Thirdly, when the window cleaning robot in the scheme cleans the glass surface, the structure of the brush piece and the wet pad is adopted, the brush piece and the wet pad move on the glass along with the robot to clean the glass surface, and the cleaning capability is limited when stubborn stains are encountered.

By setting parameters of the control module 18, the motion states of the two driving wheels 15 on the same window machine 3 are controlled to change, and steering is realized by means of the speed difference of the two driving wheels 15. For example, when the window machine 3 reaches the edge of the glass 1 under the driving of the driving wheel 15, the protruding part of the window frame touches the antenna 20, and then the switch of the micro-motion limit sensor 17 is triggered, the power supply of the stepping motor 19a is cut off by the signal of the sensor 17 through the control module 18, and the stepping motor 19a stops driving. Subsequently, the control module 18 drives the stepping motors 19a to rotate in opposite directions, the left and right driving tires start to drive in opposite directions, and the follow-up guide wheels follow the two main driving tires to achieve 90-degree steering while keeping the window machine 3 stable. Then the control module 18 cuts off the power supply of the stepping motor 19a to control the two stepping motors 19a to rotate in the same direction, the driving wheel 15 runs downwards for a certain distance (less than the width of the cleaning surface), then turns to 90 degrees by the method, then runs continuously in the reverse direction, and runs to the left frame position of the window of the glass 1 while running and cleaning, and the actions are continuously repeated. And the last cleaning is carried out until the micro-motion limit sensor 17 switch touches and bounces to the lower frame of the window, and finally when the micro-motion limit sensor 17 switch touches the window frame in the corner, the whole piece of glass 1 is cleaned completely.

During the running process, the booster pump 13 pumps out the cleaning liquid from the cleaning liquid storage bin 12 of the main machine 5, the cleaning liquid is sprayed to the surface of the glass 1 through the spraying component 10, the glass 1 is wiped by the friction between the wiping piece 22 and the glass 1, and the water stains are collected and wiped by the wiping piece 23.

It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
