Description

Anti-drop conversion sheet and method of making the same

technical field

The invention relates to the technical field of grinding devices, in particular to an anti-falling conversion sheet and a manufacturing method thereof.

Background technique

The converter is a sanding unit with a fixed sanding layer. At present, with the failure of the polishing surface on the polishing sheet, it is necessary to remove the failed polishing layer and replace it with a new polishing layer. Since the polishing layer is fixed to the substrate by an adhesive, it is difficult to remove the polishing layer and it is easy to leave glue after removing the polishing layer. Moreover, in order for the polishing layer to cover the substrate more completely, the edges of the substrate are not chamfered, so when removing the polishing sheet, the edges of the substrate are very easy to cut fingers.

SUMMARY OF THE INVENTION

In view of this, in order to solve one of the technical problems in the related art to a certain extent, it is necessary to provide an anti-detachment conversion sheet and a manufacturing method thereof, which are not only convenient for fixing the polishing sheet, but also very convenient for disassembling the polishing sheet.

The invention provides an anti-detachment conversion sheet, which includes a base plate, a fixing ring and a polishing layer. The outline of the base plate is substantially the same as the shape of the fixing ring, the polishing layer has a polishing surface, and the edge part of the polishing layer is The polishing layer is fixed on the substrate by pressing between the side surface of the substrate and the inner surface of the fixing ring, so that the opposite surface of the polishing surface is in close contact with the surface of the substrate.

Further, a positioning structure is provided on the substrate.

Further, the positioning structure is a positioning pin and/or a positioning hole.

Further, the substrate is made of magnetic material.

Further, the edge of the polishing layer is coated with adhesive to fix the edge of the polishing layer with the fixing ring and/or the substrate.

Further, the edge of the substrate is rounded.

The present invention also provides a method for making an anti-falling conversion sheet, the method comprising the following steps:

Provide base plate, retaining ring and polishing pad;

placing the polishing surface of the polishing sheet on the fixing ring and placing the substrate on the polishing sheet;

Giving the base plate a pressure to move in the direction of the fixing ring, until the edge portion of the polishing layer is pressed between the side surface of the base plate and the inner surface of the fixing ring;

The excess part of the edge of the polishing layer is cut off to obtain the anti-falling conversion sheet.

Further, a positioning structure is provided on the substrate.

Further, the positioning structure is a positioning pin and/or a positioning hole.

Further, after cutting off the redundant part of the edge of the polishing layer, the method further includes:

Adhesive is applied to the edge of the polishing layer, so that the edge of the polishing layer is fixed with the fixing ring and/or the substrate.

It can be seen from the above solutions that the present invention is provided with a fixing ring, the fixing ring is located on the outer periphery of the substrate, and the edge part of the polishing layer is pressed between the side surface of the substrate and the inner surface of the fixing ring by means of interference, so that the polishing layer can be stably It is fixed on the base plate. If the grinding surface of the grinding sheet fails, the fixing ring is separated from the base plate by external force, so as to remove the failed grinding layer and replace it with a new one, which is convenient and fast, and is beneficial to improve the grinding efficiency.

Referring to FIGS. 1-3 , an anti-detachment conversion sheet provided by an embodiment of the present invention includes a substrate 10 , a fixing ring 20 and a polishing layer 30 .

The outline of the base plate 10 is roughly the same as the shape of the fixing ring 20 , the base plate 10 can be a circular plate, and the fixing ring 20 can be a fixing ring. Edges are rounded.

The base plate 10 is provided with a positioning structure 11 , and the positioning structure 11 can be a positioning pin and/or a positioning hole, so that the anti-falling conversion sheet can be positioned and fixed on the polishing disc. In order to make the conversion plate more stably fixed on the grinding disc, preferably, the substrate 10 is made of magnetic materials (such as magnetic metal materials or magnets, etc., which are not limited here), and is provided on the grinding disc. There are strong magnets.

The polishing layer 30 has a polishing surface 31 and a smooth surface 32. The polishing layer 30 may preferably be a Velcro, and the polishing surface 31 is a hook surface of the Velcro.

Optionally, when the substrate 10 is placed in the fixing ring 20, the distance between the side surface of the substrate 10 and the inner surface of the fixing ring 20 is smaller than the thickness of the polishing layer 30. In this way, the polishing layer The edge part of 30 can be pressed between the side surface of the base plate 10 and the inner surface of the fixing ring 20 by means of interference connection, so as to fix the polishing layer 30 on the base plate 10 and make the The smooth surface 32 of the polishing layer 30 is in close contact with the surface of the substrate 10. In addition, since the friction coefficient of the polishing surface 31 of the polishing layer 30 is very large, when the edge portion of the polishing layer 30 is pressed against Between the side surface of the substrate 10 and the inner surface of the fixing ring 20, the frictional force between the grinding surface 31 and the inner surface of the fixing ring 20 is very large, so the grinding can be better prevented The layer 30 is separated from the substrate 10. If the polishing surface 31 of the polishing sheet fails, the fixing ring 20 is separated from the substrate 10 by external force, so that the failed polishing layer 30 can be removed and replaced with a new polishing layer 30, which is more convenient and fast.

In order to further improve the reliability of the polishing layer 30 being fixed, the edge 33 of the polishing layer 30 is coated with an adhesive, and the adhesive can attach the edge of the polishing layer 30 to the fixing ring 20 and/or the substrate 10 is further fixed.

Referring to Figure 4 and Figure 5, the present invention also provides a method for making an anti-detachment conversion sheet, the method comprising the following steps:

Step 1: provide the substrate 10, the fixing ring 20 and the polishing sheet;

Step 2: placing the polishing surface 31 of the polishing sheet on the fixing ring 20 and placing the substrate 10 on the polishing sheet;

Step 3: applying pressure to the substrate 10 moving in the direction of the fixing ring 20 until the edge portion of the polishing layer 30 is pressed between the side surface of the substrate 10 and the inner surface of the fixing ring 20;

Step 4: Cut off the excess part of the edge of the polishing layer 30 to obtain the anti-falling conversion sheet.

In this embodiment, after cutting off the redundant part of the edge of the polishing layer 30, the method further includes:
