[0002] Crystal polishing is an important process, the purpose of which is to remove burrs, scratches and other defects on the surface of crystal parts, and improve their surface smoothness and aesthetics. Polishing is a processing method that mainly uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It is a modification of the workpiece surface using polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is aimed at obtaining a smooth surface or mirror gloss, and is sometimes used to eliminate gloss (matte).

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0027] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0028] According to the first aspect of the present utility model, Figure 1-Figure 2As shown, some embodiments of the present invention disclose a crystal polishing jig 100, which includes: a main body 110; a polishing area 130 arranged on the main body 110, the polishing area 130 includes at least one first polishing area 131 and at least one second polishing area 135, the first polishing area 131 and the second polishing area 135 are used to receive crystal pieces with different crystal cut faces; and a platform 150 connected to the main body 110, the platform 150 can be fixed on a polishing machine platform (not shown in the figure). The crystal polishing jig 100 described in the present invention can adapt to crystal pieces of different shapes and sizes by setting different polishing areas, thereby improving the versatility of the polishing jig; the crystal polishing jig 100 described in the present invention solves the shortcomings of the polishing jig, such as complex structure, high manufacturing cost, and inconvenient operation.

[0029] In some embodiments, the surface of the body 110 including the plurality of first polishing regions 131 and the plurality of second polishing regions 135 is an axisymmetric figure. The body 110 may be a cube, a cylinder or other three-dimensional structure. When the body 110 is a cube, the plurality of first polishing regions 131 and the plurality of second polishing regions 135 may be symmetrically arranged with the middle axis of the surface or cross section of the body 110 as the axis of symmetry. When the body 110 is a cylinder, the plurality of first polishing regions 131 and the plurality of second polishing regions 135 may be symmetrically arranged with one of the diameters of the surface or cross section of the cylinder as the axis of symmetry. When the body 110 is other three-dimensional structures, the plurality of first polishing regions 131 and the plurality of second polishing regions 135 may be arranged with any axis of the surface or cross section of the three-dimensional structure as the axis of symmetry.

[0030] In some embodiments, the first polishing area 131 is used to receive the crystal piece 121 with a long side cut surface, and the second polishing area 135 is used to receive the crystal piece 122 with a short side cut surface. The first polishing area 131 and the second polishing area 135 can be used to place cut surfaces of different lengths and different angles, thereby improving the versatility of the crystal piece polishing jig 100. Moreover, the crystal piece 121 with a long side cut surface and the crystal piece 122 with a short side cut surface have different extension directions in the crystal piece polishing jig 100. Figure 1 and 2 In the embodiment shown, the crystal piece 121 with a long cut surface and the crystal piece 122 with a short cut surface extend perpendicularly to each other in the crystal piece polishing jig 100. In addition, the top of at least a portion of the crystal piece 120 placed therein is located above the plane of the main body 110 (at Figure 3As shown in FIG. 1 , at least two cut surfaces of the top of the crystal piece 120 can be located above the plane of the main body 110, which is more conducive to improving the efficiency of polishing. In the past, due to the difference in height of each surface, abrasive grinding or brushing would be selected for polishing. However, due to the structure of the crystal piece polishing jig 100 described in the utility model, it is not necessary to change the material on the polishing machine back and forth.

[0031] In some embodiments, Figure 1 As shown, the body 110 is a cube, the number of the first polishing regions 131 is four, the four first polishing regions 131 are located at the four corners of the body 110, and the second polishing region 135 is located in the middle of the four first polishing regions 131. The number of the second polishing regions 135 is two. Figure 1 The crystal polishing jig 100 is symmetrically arranged in a square shape and includes five polishing areas. The five polishing areas can be polished simultaneously, thereby improving the polishing efficiency.

[0032] In some embodiments, the number of first polishing regions 131 may be other than four, and the number of second polishing regions 135 may be other than two. The specific number of each polishing region may be set as required, which is within the protection scope of the present invention.

[0033] In some embodiments, the platform 150 is a truncated table, and the crystal polishing fixture 100 further includes screw holes 151 arranged along the circumference of the truncated table. Multiple screw holes 151 can be arranged at equal distances along the circumference of the truncated table, and the entire crystal polishing fixture 100 can be fixed on a polishing machine platform (not shown in the figure) through the screw holes 151. The polishing machine platform can be a platform for fixing the polishing machine and its related components, or other devices that can achieve the fixation of the polishing machine and its related components.

[0034] In some embodiments, the main body 110 is made of acrylic or aluminum, and the platform 150 is made of bakelite, and the main body 110 and the platform 150 are fixed together by an adhesive. Acrylic and aluminum materials have a longer service life.

[0035] In some embodiments, the first polishing region 131 and each of the second polishing regions 135 are recessed portions formed on the body 110 , and the body 110 , the first polishing region 131 , and the second polishing region 135 are integrally formed.

[0036] In some embodiments, each first polishing area 131 and each second polishing area 135 are configured to receive a plurality of overlapping crystal pieces. Figure 2As shown), multiple crystals can be polished each time, thereby improving the polishing efficiency.

[0037] In some embodiments, the overlapping placement of multiple crystal pieces and the fact that at least two cut surfaces of at least a portion of the received crystal pieces are partially located above the plane of the main body 110 both improve the polishing efficiency.

[0038] According to the second aspect of the present invention, Figure 3 As shown, some embodiments of the utility model disclose a device 200 for polishing crystal pieces, which includes: the crystal piece polishing fixture 100 described in the aforementioned embodiments; and a polishing machine frustum 170, the polishing machine frustum 170 is located above the crystal piece polishing fixture 100, and a variety of components for polishing are arranged on the surface of the polishing machine frustum 170 facing the crystal piece polishing fixture 100.

[0039] In some embodiments, the main body 110 of the crystal polishing jig 100 is fixed on the platform 150 of the crystal polishing jig 100, and the platform 150 is fixed on the polishing machine platform (not shown in the figure). The polishing machine round table 170 can also be fixed on the polishing machine platform, and the polishing machine round table 170 can rotate to polish the crystal piece 120 fixed on the main body 110.

[0040] In some embodiments, the component used for polishing includes a brush head 171. The brush head 171 can be set on the surface of the polishing machine table 170 facing the crystal polishing fixture 100 in a desired manner (for example, set as a whole or set in different concentrations in different areas). When the polishing machine table 170 is running, the crystal piece fixed on the main body 110 can be polished at multiple angles. Since multiple facets of the crystal piece are exposed on the surface of the main body 110, the brush head 171 can be used to polish different facets at the same time, thereby improving the polishing efficiency. As needed, additional grinding heads and other components used for polishing can also be set on the surface of the polishing machine table 170 facing the crystal polishing fixture 100.

[0041] In some embodiments, the polishing machine table 170 is further connected to a high-precision motor (not shown in the figure) and is equipped with a corresponding driving circuit and a control circuit board to achieve precise polishing movement.

[0042] The technical solution of the utility model is described below in conjunction with specific embodiments:

[0043] Combination Figure 1As shown, the utility model provides a currently optimal crystal polishing jig 100, which includes a plurality of first polishing areas 131 and a plurality of second polishing areas 135. In this embodiment, the first polishing area 131 is a long side facet polishing area, and the second polishing area 135 is a short side facet polishing area. The crystal polishing jig 100 can be connected to the polishing machine platform by passing an additional countersunk screw or bolt through the screw hole 151 on the platform 150. The long side facet polishing areas of the crystal are arranged in a symmetrical manner at four locations, and the short side facet polishing is in the middle. The main body 110 is fixed to the platform 150 by glue bonding. The crystals can be arranged in a stacked manner to utilize the maximum space to produce more products and improve efficiency. In the past, a polishing jig with 5 people in one shift polished about 50 finished products. After the improved jig, the same 5 people in one shift can produce about 500 pieces, and the efficiency is increased by 10 times.

[0044] The structure of the present invention is more stable. Previously, the single-piece fixed polishing of the crystal piece was prone to edge collapse and low yield. The stacked arrangement of the fixture 100 described in the present invention has strong stability, a larger polishing contact area, and a better yield.

[0045] Furthermore, the jig 100 of the present invention is made of acrylic, which has better chemical and weather resistance; because the jig has a longer service life than ABS, the frequency of jig replacement is reduced. The platform 150 is made of bakelite.

[0046] Furthermore, since the arrangement and layout of the previous jigs often causes a series of problems such as crystal breakage, edge collapse, and edge collapse, the jig 100 described in the utility model adopts a stacking arrangement, multiple crystal pieces overlap together, increasing the contact area with the polishing brush and the force-bearing area, thereby improving the yield.

[0047] Furthermore, before the improvement, the number of polishings per time by the fixture was small, and the number of good products was even smaller. One person could produce about 10 good products per shift, while the loading capacity of the fixture 100 described in the utility model was increased by 10 times compared with before, and the number of polishings was reduced by half; at the same time, the number of operators required was reduced compared with before, and now one person can produce about 100 good products per shift, and the output has increased accordingly.

[0048] Compared with the jig in the prior art that is bolted and locked on four sides and has crystal products placed in the middle (the jig is not easy to operate, and it takes about 1 hour to install and disassemble, which increases the time cost. At the same time, only one surface can be polished at a time, and the polishing efficiency is low), the jig 100 described in the utility model has a simple structure, is easy to operate and has a high polishing efficiency; compared with the jig in the prior art that is fixed on one side of the crystal piece (there is a certain risk of edge collapse during mechanical polishing), the jig 100 described in the utility model is an integral structure, and on this basis, the insertion and fixation is changed to a stacking type, which greatly increases the loading capacity, reduces the risk of edge collapse of the single-piece type, and can polish multiple surfaces at the same time, which greatly improves the efficiency.

Therefore, the combinations formed by these reasonable arrangements and combinations should also fall within the scope of protection of the present utility model, and the scope of protection of the present utility model should not be limited to the embodiments.
