Description

Glass panel polishing machine {Abrasive blasting machine for glass panel}

The present invention relates to an apparatus for effectively polishing a large glass panel.

In particular, by applying the method of polishing the glass panel while revolving and rotating the two combination polishing machines, it is possible to effectively polish the large glass panel, and also to raise and lower the table on which the glass panel is placed. Applying a structure that can move the entire bed including the table back and forth to facilitate the loading and unloading of large glass panels, ultimately to improve the workability and productivity related to the polishing of large glass panels It is to improve the quality of the product by increasing the precision of polishing.

In general, the direct-view flat glass panel used in flat panel liquid crystal TVs, notebook computers, flat panel computers, and the like performs polishing on the surface for precise flatness.

Conventional glass panel polishing apparatus is a method of polishing the surface of the glass panel while supplying the abrasive while at the same time rotating the glass panel is placed on top, contact with the polishing machine disposed at the bottom.

In addition, in order to increase the effect of the polishing operation on the glass panel, a method of swinging the top plate and the entire substrate including the glass panel from side to side is applied.

As the conventional polishing method as above, the worker lifts the glass panel by hand to fix it from the bottom up, so the work process is difficult, inconvenient, and risks of falling off, and during operation, the worker cannot check the polishing state of the glass panel. In general, work time and productivity are deteriorated, such as a considerable amount of time is required.

In addition, in recent years, as electronic devices such as computers and TVs are enlarged in size, the size of glass panels is gradually increasing, and there is a disadvantage in that it is difficult to handle a surface of such a large-area glass.

In addition, by applying a method of swinging the top plate and the entire substrate including the glass panel to the left and right, excessive friction occurs when the direction is changed, and the holder and the glass panel collide with each other, resulting in the edge portion of the glass panel There is a disadvantage in that the accuracy of the overall flatness is falling, such as excessive wear and tear.

In order to solve the above disadvantages, the glass panel is firmly fixed by the carrier means and the polishing process for the glass panel is performed while the polishing machine is rotated, but this also requires the operation from bottom to top when replacing the glass panel. There is a problem in that it is difficult to handle a large weight and bulky large glass panel.

In particular, most of the existing polishing apparatuses are suitable for small glass panels by simply rotating a single polishing machine, and simply rotate such a single polishing machine on a large glass panel recently released. Application is inefficient in terms of handling related to loading / unloading of the product, workability and productivity in terms of working speed, and precision in terms of the wide working area of the glass panel, that is, in terms of product quality.

Accordingly, the present invention has been devised in view of such a point, and by applying the method of polishing the glass panel while revolving and rotating the two combined grinders, the large working area of the large glass panel can be sufficiently covered, and accordingly The purpose is to improve workability and productivity, such as shortening the working time.

In addition, the present invention by using a combination grinding machine that performs the polishing operation while rotating and rotating, it is possible to uniformly polish the entire working area of the large glass panel, thereby improving the accuracy of the overall flatness of the glass panel, such as product quality There are other objectives to help improve.

Still another object of the present invention is to employ a table and a bed sufficient to set a large glass panel, and to work or load / unload the large glass panel through the lifting structure of the table and the forward and backward structure of the entire bed. By making it easy to move to the area, it is possible to simplify the handling of workers to increase the efficiency of the overall work, and to completely eliminate the risk of safety accidents.
