[0021] The adjustable light sweeping fixture of the present invention is described below in conjunction with the accompanying drawings.

[0022] In the first embodiment of the present application, Figures 1 to 5 As shown, the adjustable light sweeping fixture (hereinafter referred to as "this patent") includes a light sweeping machine turntable 1, a base cavity 1-1, a base 2, a longitudinal guide rail 2-1, a side plate 3, a side plate screw hole 3-1 and a baffle connecting screw hole 3-2. The light sweeping machine turntable 1 has three base cavities 1-1 on its surface, the base 2 is inserted into the matching base cavity 1-1, three longitudinal guide rails 2-1 are parallelly formed on the base 2, and side plates 3 have side holes corresponding to the three longitudinal guide rails 2-1 on their lower surfaces. The screws pass through the longitudinal guide rail 2-1 of the base 2 and fix the respective side panels 3 through the side panel screw holes 3-1 respectively. The baffle connecting screw holes 3-2 are opened on the sides of the two side panels 3. The longitudinal baffles 4 on both sides of the two side panels 3 are fixed by screws screwed into the baffle connecting screw holes 3-2. The base 2, the side panels 3 and the longitudinal baffles 4 form a cavity; the longitudinal baffle 4 is divided into two side panels 4-1, and the two side panels 4-1 are connected by an elastic telescopic belt 4-2.

[0023] The utility model number is CN209648415U, which is a straight-body sweeping fixture and sweeping device for sapphire glass sheets (hereinafter referred to as "the patent"). The positioning groove of the patent is a fixed shape, especially it can only process sapphire watch mirrors, and cannot cope with products of various parameter sizes, which is not very convenient to use. However, the patent forms a cavity that adapts to sapphire wafers of various sizes and parameters by adjusting the spacing of the side panels 3 and the base 2. By loading multiple sapphire wafers into the cavity for rapid processing, there is no need to frequently replace the jig, which can effectively reduce production costs. Since the cavity space for accommodating sapphire wafers is relatively ample, the product can be polygonal or circular.

[0024] The structure of the second embodiment is basically the same as that of the first embodiment, except that the base 2 is two centimeters thick and the base cavity 1-1 is two centimeters deep. The base 2 is directly stuck in the base cavity 1-1 due to its greater thickness.

[0025] In order to further optimize the working efficiency of the present application, the base 2 is further fixed, and the base cavity 1-1 is provided with a protrusion matching the groove 2-2 of the base 2. In order to reduce production costs, the sweeper turntable 1, base 2 and side plate 3 are all made of resin material. In order to further strengthen the longitudinal single plate 1 4, the longitudinal baffle 1 4 is provided with a longitudinal baffle 2 5 on one side facing inward, and the two sides of the longitudinal baffle 2 5 are embedded in the L-shaped groove of the side plate 3, and the width of the longitudinal baffle 2 5 is 35 to 50 mm.

[0026] When in use, the adjustable scanning fixture is installed and adjusted accordingly according to the parameter size of the sapphire wafer, and the fixture can be put into use.

[0027] When the utility model is in use, the specific operations are as follows:

[0028] When in use, according to the parameter size of the sapphire wafer to be processed, first loosen the screws connected to the side plate screw holes 3-1 on the longitudinal guide rail 2-1 of the base 2, adjust the size between the two side plates 3 along the longitudinal guide rail 2-1, and after adjusting to the right position, re-tighten the screws connected to the side plate screw holes 3-1 on the longitudinal guide rail 2-1 of the base 2. When adjusting the size between the two side plates 3, since the two side plates 4-1 of the longitudinal baffle 1 4 are connected by an elastic telescopic belt 4-2, the longitudinal baffle 1 4 will also change size. Install the longitudinal baffle 2 5 of the corresponding size into the inner side of the longitudinal baffle 1 4. After the adjustment is completed, several sapphire wafers can be placed in the fixture cavity, and finally the base 2 is embedded in the base cavity 1-1 of the sweeper turntable 1, and the fixture can be placed in the processing equipment, and the edge can be swept and polished with a brush. After the sweeping and polishing is completed, the sapphire wafer can be taken out.

[0029] In summary, the adjustable scanning jig of the embodiment of the utility model can adapt to sapphire wafer products of various parameter sizes through the side plates 3 with adjustable spacing and the longitudinal baffle 4 with selectable width according to needs, in conjunction with the base 2 for fixing the side plates 3 and the scanning machine turntable 1, without the need to frequently replace the jig, which can effectively reduce production costs.

[0030] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
