Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method and apparatus for cleaning glass surfaces, and more specifically, for example, when applying a solvent such as a primer around the windshield or windshield of an automobile. The present invention relates to a cleaning device for applying a cleaning solvent that removes dirt from the peripheral surface of glass in advance.

[Conventional technology]

Generally, when assembling a windshield or windshield of an automobile to a body, dirt is removed from the peripheral surface of the glass, and a sealing material, primer, etc. is applied to that area.

When applying a sealant or primer around the glass, conventionally, in order to remove dirt from the glass surface,
A piece of glass is cleaned using the same cloth, which is soaked in a solvent and held by hand or a robot.

[Problem that the invention attempts to solve]

However, cleaning the glass surface manually is not only inefficient, but also increases costs.
Furthermore, since a solvent is used, there is a safety problem, and when cleaning by a robot, there is a problem in that it is difficult to clean the glass if the cleaning area is narrow.

In addition, as a conventional cleaning device, the applicant of the present application

This cleaning solvent application cleaning device includes an unwinding roll wound with a nonwoven fabric in a roll shape, and a drive roll that winds up the nonwoven fabric, which are detachably attached to a frame at a predetermined interval.
A pressing means having a rotatable roller at the tip for pressing the nonwoven fabric against the glass surface with a predetermined elastic force is provided between the unwinding roll and the driving roll, and a pressing means is provided on the back side of the nonwoven fabric behind the cleaning section. A solvent supply means is provided to periodically supply a solvent to the nonwoven fabric, and the nonwoven fabric is impregnated with the solvent and is pressed against the glass surface with a predetermined elastic force while being rolled up and slid. It is designed to automatically clean dirt, etc. from the surface of the screen.

However, this cleaning device for applying cleaning solvent cleans while pressing the nonwoven fabric against the glass surface via a roller.
There were problems in that the ability to follow the curved surface of the glass was insufficient and that reliable cleaning work could not be performed due to restrictions on the width of the roller.

[Purpose of the Invention] The present invention was devised in view of the above-mentioned problems in the prior art, and has good followability to curved glass surfaces and is not limited by the roller width, so that reliable cleaning work can be performed. Another object of the present invention is to provide a method for cleaning a glass surface and an apparatus therefor, which allows cleaning to be performed easily even in a narrow space.

A pair of left and right guide members that can move forward and backward are equipped with a drive device that unwinds the nonwoven fabric and presses it against the glass surface. A brush is provided at the tip between the pair of left and right guide members, and a brush is provided between the pair of left and right guide members to press the nonwoven fabric against the glass surface. The gist is that a pressing means that presses with a predetermined elastic force can move forward and backward, and that a solvent supplying means that periodically supplies a solvent to the nonwoven fabric is provided inside the brush of the pressing means.

[Action of the invention]

This invention is configured as described above, and a nonwoven fabric stretched between an unwinding roll and a driving roll is wound by protruding a pair of left and right guide members provided between the unwinding roll and the driving roll. At the same time, the guide members are brought into pressure contact with the glass surface, and in this state, the brush of the pressing means provided between the guide members is projected and pressed until it comes into contact with the nonwoven fabric, and then the pair of left and right guide members are moved to the standby position. The nonwoven fabric pressed by the brush is moved along the glass surface while periodically supplying a solvent from the solvent supply means to the inside of the brush, and the glass surface is cleaned by following the curved surface of the glass. It has good performance and is not limited by the width of the roller, allowing reliable cleaning work.
