Description

Online trimming device of glass grinding pad

Technical Field

The invention relates to the technical field of glass surface grinding, in particular to an online trimming device for a glass grinding pad.

Background

The surface grinding of glass needs to use a grinding pad to grind the surface of the glass, for large-size glass, a plurality of groups of parallel grinding heads are generally adopted at the present stage, a grinding disc is pasted with the grinding pad, and the grinding disc is fixed on a grinding disc support by fastening screws. In order to ensure the uniformity of the polishing pad on the glass surface, the working surface of the polishing pad is required to have consistent height. In order to keep the glass surface free from scratches and grinding marks during grinding, it is required that the pad surface be flat and free from foreign matters.

In practice, there are several factors that affect the flatness of the polishing pad:

firstly, the polishing pad is usually made of polyurethane material, and slight height difference may exist on the surface of the polishing pad due to non-uniform foaming temperature and foaming pressure during foaming.

And secondly, coating double-sided adhesive tape on the back surface of the grinding pad, and adhering the grinding pad on the grinding disc by using the double-sided adhesive tape. Slight air bubbles between the polishing pad and the polishing disk during the bonding operation may cause a difference in the height of the polishing pad surface.

Third, the polishing pad is usually grooved on the surface of the polishing pad for guiding the polishing slurry during use, and the grooving process may cause the grooves to be uneven.

And fourthly, the grinding pad is pasted on the surface of the grinding disc by using a double-sided adhesive tape, the grinding disc is fixed on the grinding head by using screws, and the disc surface is possibly warped due to uneven stress in the fixing process of the grinding disc.

And fifthly, foreign matters such as glass scraps, grinding powder residues and grinding pad scraps are adhered to the surface of the grinding pad after the grinding pad is used for a period of time, and the grinding disc needs to be corrected regularly.

Sixthly, after the grinding pad is used for a short time, the cutting force of the grinding pad is reduced due to the fact that residual liquid of the surface pits is blocked, and then the whole correction is required to be carried out in time.

Synthesize above six reasons, the grinding pad glues before using on the abrasive disc and need use the grinding pad trimming device to regularly maintain in the use, and the grinding pad surface height after guaranteeing to maintain is unanimous, and the notch is level and smooth, and the quotation does not have the foreign matter to guarantee abrasive disc's cutting force and work efficiency.

In the conventional method, a special polishing pad corrector is used for off-line trimming of a polishing pad, and the polishing pad is trimmed by the polishing pad trimmer after being attached to a polishing disk surface. The surface of the grinding pad which is trimmed singly can be ensured to be uniform in height, and the notch is smooth.

The use of off-line trimming has the following problems:

first, the polishing pads are separately dressed, so that the polishing pads can be guaranteed to have uniform height in a single polishing process, but the consistency of the dressing heights of a group of polishing pads cannot be guaranteed.

Secondly, the disk surface warps due to uneven stress during fastening in the process of installing the polishing pad on the polishing machine after finishing, and the height of the polishing pad is possibly inconsistent.

Thirdly, the polishing pad has long time consumption for respectively dressing and low efficiency.

Disclosure of Invention

The invention aims to provide an online trimming device for glass grinding pads, which can synchronously perform online trimming on the grinding pads on a plurality of grinding heads under the condition of not removing the grinding pads, ensure that the heights of a group of grinding pads repaired at each time are kept consistent, effectively avoid disc surface warping caused by fastening after trimming and improve the trimming efficiency.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the utility model provides an online trimming device of glass grinding pad, includes the trimming tray, and the trimming tray is the same with glass tray shape structure, and the trimming tray top surface is equipped with a set of mounting hole, and the mounting hole is array distribution, inlays in the mounting hole and is equipped with the diamond abrasive material, and the top surface height of diamond abrasive material is unanimous with the height behind the glass tray bearing glass.

Furthermore, a height adjusting gasket is arranged on the bottom surface of the trimming tray.

The diamond grinding material trimming device has the beneficial effects that when the grinding pad needs to be trimmed, the glass tray is taken down, the trimming tray is replaced, the grinding pad is driven by the grinding tray to descend to contact with the diamond grinding material, and the grinding pad can be trimmed through the diamond grinding material when rotating; the same group of grinding pads are simultaneously trimmed on line without dismounting the grinding disc, the surface heights of all the grinding pads are consistent after trimming, the notches are smooth, and the trimming effect and the trimming efficiency are improved.

Drawings

The invention is further illustrated with reference to the following figures and examples:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a top view of the present invention;

fig. 3 is a schematic diagram of the use of the present invention.

Detailed Description

Referring to fig. 1 and 2, the invention provides an online trimming device for a glass polishing pad, which comprises a trimming tray 1, wherein the trimming tray 1 has the same shape and structure as the glass tray, a group of mounting holes 2 are formed in the top surface of the trimming tray 1, the mounting holes are distributed in an array manner, diamond abrasives 3 are embedded in the mounting holes 2, and the height of the top surface of the diamond abrasives 3 is consistent with the height of the glass tray after supporting glass. The bottom surface of the dressing tray 1 is also provided with a height adjusting spacer 4.

Referring to fig. 3, when the polishing pad 5 needs to be dressed, the glass tray is removed, the dressing tray is replaced, the polishing disk 6 drives the polishing pad 5 to descend to contact the diamond abrasives 3, and the polishing pad 5 can be dressed by the diamond abrasives when rotating; the same group of grinding pads are simultaneously trimmed on line without dismounting the grinding disc, the surface heights of all the grinding pads are consistent after trimming, the notches are smooth, and the trimming effect and the trimming efficiency are improved.

The height adjustment pad 4 can be used to compensate for the height difference of the diamond abrasive dressing pad wear.

When the glass surface is ground, if fragments occur in a machine table, the surface grinding glass has scratches and the like and needs to be dressed on a grinding pad, and the grinding pad is directly dressed on line by using the dressing device without dismounting the grinding disc. The grinding efficiency can be corrected in time after the grinding disc is used for a period of time and the grinding efficiency is reduced, so that the disc repairing efficiency is improved, and the production efficiency is improved.

The foregoing is merely a preferred embodiment of the invention and is not intended to limit the invention in any manner; those skilled in the art can make numerous possible variations and modifications to the present teachings, or modify equivalent embodiments to equivalent variations, without departing from the scope of the present teachings, using the methods and techniques disclosed above.
