Description

Window cleaning robot Field of invention

The invention relates to a window cleaning robot, and in particular to a window cleaning robot that can pressurize and move the window glass by climbing on columns on both sides of the window glass.

Background technique

Cleaning the glass curtain walls of high-rise buildings is a dangerous and inefficient work. It is completely dependent on manual work. Someone invented a commercial automatic window cleaning machine that uses multi-axis drone technology to press the window cleaning machine suspended outside the window to the glass curtain wall. Robots, however, this pressurization method consumes high energy, has a complex and expensive structure, and once the parts fall, the consequences will be disastrous.

Some people have also invented some small civilian window cleaning robots, which have built-in small air pumps to pump out the air close to the window glass through the internal and external pressure difference fixing device. This method has a simple structure and low cost. While power is transmitted through cables, it can also play a role in preventing equipment from falling to a certain extent (the cable strength is sufficient). However, the efficiency of the low-pressure manufacturing of the air pump and the strength of the window glass jointly limit the weight of the equipment, so it cannot meet the needs of spraying washing liquid, wiping, wiping, and even cleaning and replacing rags, and efficient continuous operation. Consumers can only manually soak the window cleaning robot with detergent, clean and replace its wipes to complete the entire process. It can only be said that the risk of people falling from a height is avoided, and it is far from fully automatic window cleaning.

There are two common building structures: inner load-bearing and outer load-bearing. The internal load-bearing uses the entire glass curtain wall to support the load through the internal columns; the external load-bearing mainly relies on the load-bearing wall, if the single room is too large, the load-bearing column is also needed. For the internal load-bearing glass curtain wall, almost all glass, the strength of the frame between the glass is not enough to bear the weight of the window cleaning robot itself and the extra grip required for the operation; for the external load-bearing, if each glass window has both sides It is a symmetrical column, and the column is load-bearing, and its strength is at least sufficient to support the additional gripping force required by the window cleaning robot, even the weight of the window cleaning robot.

Consumers need a fully automatic window cleaning robot that can automatically complete the entire window cleaning process, with high energy efficiency and low noise.

Summary of the invention

It is possible to imagine a window cleaning robot in which the uprights on both sides of each glass window are fixed by tightening mechanical clamps. If the strength of the column is insufficient, or its surface strength is insufficient, for example, the design of ceramic tiles, test the maximum strength it can withstand before use. If the strength is sufficient to support the weight of the window cleaning robot and the extra grip required for the operation, it can be used in All window cleaning robots that move freely between the window glass and the uprights will still bear the weight of the window cleaning robot through the traditional suspension, and only provide the extra grip required for the work through the two uprights.

In this way, it can support a heavy-weight, fully automatic window cleaning robot that completes all spraying, wiping, wiping, and even cleaning and replacement of rags, and the entire process of continuous operation. For commercial office buildings, if a fully automatic window cleaning robot is implemented, it is completely possible to clean the glass curtain wall of the entire building at night or on weekends, and then the window cleaning robot can be maintained and transported during the day.

The content of the present invention is not meant to be restricted or restricted in any way, and the present invention disclosed herein will be understood by one of the following: The technical staff includes obvious improvements and modifications.

Detailed ways

The present invention will now be described more fully hereinafter. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Hopefully, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

It should be understood that various changes can be made to the function and arrangement of elements without departing from the spirit and scope set forth in the appended claims. Therefore, the embodiments are examples or implementations of the present invention, rather than the only implementations. The various appearances of "one embodiment," "an embodiment," or "some embodiments" do not necessarily all refer to the same embodiment. Although various features of the invention may be described in the context of a single embodiment, the features may also be provided individually or in any suitable combination. Conversely, although the invention may be described herein in the context of separate embodiments for the sake of clarity, the invention may also be implemented in a single embodiment or any combination of embodiments.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present invention belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of related technologies and the present disclosure, and will not be interpreted as idealized or excessive The formal meaning, unless explicitly defined as such in this article.

Reference terms such as "left", "right", "top", "bottom", "front", and "rear" are intended to be used in the implementation of the present invention in relation to the specific features, structures, or orientations of the depicted embodiments example. Obviously, such directional terms regarding the actual use of the device have no specific meaning, because the device can be used by a user or multiple users in multiple directions.

The mechanical arm provides the extra grip required for work, which can pressurize the outer surface of flat materials such as glass curtain walls, which is the key to the window cleaning robot. After all, except for unconventional landmark buildings, most architectural glass is vertical. The weight of the industrial-grade window cleaning robot itself can be solved by the suspension cable, and its movement can also be solved by the pulley block and the motor installed on the top of the building. There is no other source of extra grip.

There are two consumer-grade window cleaning robots on the market, both of which are made by air pumps to absorb the low air pressure of the window glass. When moving on the surface of the window glass, there are two designs: the integrated robot uses airflow or rollers to move Mobile; the split robot is a bit like a worm, through two or more split limbs, some limbs are used for fixation, and some are used for movement, so as to achieve greater pressure on the window glass and single movement and wiping distance. The former is highly efficient, and the latter inevitably has repeated wiping in order to avoid the dead corners that are not cleaned, but the wiping is cleaner. Because the latter can exert more pressure.

The tightening mechanical clamps on the robot arm are used to fix the columns on both sides of the glass window. The lack of strength of the columns or the insufficient surface strength must be considered. For example, the strength of surface tiles and insulation materials are very low. This can be tested by actual operation on the low floor to choose an external suspension cable or a robotic arm to bear most of the weight of the window cleaning robot.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention. Various changes and modifications according to the claims and specification of the present disclosure are still within the scope of the claimed invention. In addition, each embodiment and claims may not include all the disclosed advantages or special tightening mechanical clamping properties. In addition, the abstract and title are only used to facilitate searching of patent documents and are not intended to limit the scope of the claimed invention in any way.
