Detailed ways

The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

FIG. 1 is a schematic diagram of a polishing fixture according to an embodiment of the present invention. The polishing jig 100 comprises a template 110 and a bearing 120, wherein a bearing hole 112 (as shown in FIG. 3 ) is arranged in the middle of the template 110, and several slots 114 are provided on the template 110 for a plurality of substrates (such as: after cutting) The small-sized panel) 102 is pierced and engaged, and then carried on the template 110, wherein the substrate 102 carried can slightly protrude from the opposite side of the template 110 carrying surface after the slot 114 is pierced according to the actual polishing requirements, so that The edge portion of the substrate 102 protruding from the template 110 is beneficial for polishing. In addition, the shapes of the bearing 120 and the bearing hole 112 are not limited to those shown in FIG. 1 and FIG. During the grinding action, it is convenient to drive the components connected in series by the bearing 120 to rotate at the same time. In addition, the slots 114 are disposed obliquely relative to the surface of the template 110 , so that the substrate 102 is obliquely carried on the template 110 . Fig. 2 is a schematic diagram of a substrate obliquely carried on a template according to an embodiment of the present invention. As shown in FIG. 1 and FIG. 2 , the angle formed between the slot 114 and the vertical surface of the loading surface of the vertical template 110 may be about 0-50 degrees, so that the substrate 102 is tilted about 0-50 degrees to carry the load. on the template 110.

On the other hand, the bearing 120 passes through the bearing hole 112 in the middle of the template 110 and fixes the template 110 . In one embodiment, the template 110 is made of Teflon material, and the number of slots 114 thereon is about 3-60, but it is not limited thereto, and can be adjusted according to actual needs. In addition, the width of each slot hole should be slightly smaller than the thickness of the substrate, so that when the substrate is inserted into the slot hole, it receives a larger clamping force, preventing the substrate from slipping out of the slot hole during the grinding process.

FIG. 3 is a disassembled schematic diagram of the polishing jig shown in FIG. 1 . As shown in Figure 3, the slots 114 can be evenly distributed on the template 110 in a circular radial shape, and the bearing 120 can include a first connecting piece 122 and a second connecting piece 124, and the first connecting piece 122 and the second connecting piece The first ends of 124 are connected and fixed through the bearing hole 112 , so as to fix the template 110 between the first connecting part 122 and the second connecting part 124 . It is worth noting that the positions of the first connecting member 122 and the second connecting member 124 can be replaced with each other. In this way, when the substrate 102 needs to change sides for polishing, it is not necessary to remove the supported substrate 102, but It is only necessary to replace the positions of the first connecting member 122 and the second connecting member 124 with each other. In one embodiment, after the first connector 122 and the second connector 124 are combined with the template 110, the first connector 122 will protrude from the surface of the template 110 by about 0.5-5 millimeters (mm), and the second connector 124 Then protrude from the surface of the template 110 by about 10-70 millimeters (mm).

Compared with FIG. 3 , the slots 114 a are distributed in three regions on the template 110 a , wherein the slots 114 a in each region are parallel to each other and form the same angle with the slots in other regions. In this embodiment, the angles formed between the slots in two adjacent areas are about 120 degrees.

In addition, the polishing jig 100 may further include a cover plate, which is configured to be disposed above the substrate 102 carried by the template 110 when carrying the substrate 102 . FIG. 5A is a schematic diagram of a polishing jig auxiliary part according to an embodiment of the present invention. Please refer to Figure 1, Figure 2 and Figure 5A at the same time, the cover plate 130 can be designed as a flat cover or a hollow cover according to actual needs, and a through hole 132 is provided in the middle for the bearing 120 to penetrate, and the cover plate A cover 134 may be further provided on the cover 130 to facilitate the operator to take the cover 130 . When the substrate 102 is loaded on the template 110, the cover plate 130 can be arranged above the loaded substrate 102 to assist in fixing the loaded substrate 102 and apply a certain pressure to the loaded substrate 102, while the bearing 120 The second end of the second connecting piece 124 thus passes through the through hole 132 of the cover plate 130 .

Furthermore, the polishing jig 100 may further include a counterweight 140 for being disposed on the cover plate 130 to assist in applying extra pressure to the supported substrate 102 . In one embodiment, the weight of the counterweight 140 is about 0.5-2Kg. In addition, another through hole 142 is further provided in the center of the counterweight 140 for the covering portion 134 of the cover plate 130 to pass through, and the height of the covering portion 134 can be greater than or equal to the thickness of the counterweight 140 . In one embodiment, the counterweight 140 is in the shape of a concentric circle, with an outer diameter of about 100-150 millimeters (mm), and an inner diameter of about 20-60 millimeters (mm). When the height of the cover portion 134 is greater than the thickness of the counterweight 140 to a considerable extent, the operator can add a plurality of counterweights 140 of different weights or the same weight to the cover 130 according to actual needs, so as to increase required pressure.

FIG. 5B is a schematic diagram of a cover plate according to another embodiment of the present invention. Compared with FIG. 5A , the cover 130a is provided with another cover portion 134a in the form of a handle, so that the operator can take the cover 130a more conveniently. Similarly, when the substrate 102 is loaded on the template 110, the cover plate 130a can be disposed above the loaded substrate 102 to assist in fixing the loaded substrate 102 and apply a certain pressure to the loaded substrate 102. At this time, the bearing The second end of the second connecting piece 124 in 120 will therefore pass through the through hole 132a of the cover plate 130a.
