[0002] Our company uses the guided mold method to produce rare earth eutectic phosphors. The process method is detailed in the Chinese invention patent with announcement number CN110983433A, which discloses a process method for producing rare earth eutectic phosphors using the guided mold method. In this process method, seed crystals are required as the basis for guiding crystal growth, such as Figure 1 , 2 The figure shows the structure of the seed crystal 23 and the seed crystal clamp 22 used in the present process, wherein the seed crystal is in the shape of a rectangular parallelepiped, and its upper end is cut into a trapezoidal clamping portion 24, with sharp-angle cuts 25 on both sides of the clamping portion, and two clamping surfaces are formed on both sides of the bottom edge of the clamping portion; the clamping portion 24 at the upper end of the seed crystal 23 is inserted into the trapezoidal clamping groove of the seed crystal clamp 22, and the clamping surface contacts and rests against the bottom surface of the seed crystal clamp 22.

[0003] The seed crystal raw material is in the shape of a cuboid, and the triangular parts on both sides of the clamping part need to be cut off by a wire cutting machine.

[0030] Example 1

[0031] A seed crystal special-shaped cutting fixture, such as Figure 5 FIG. 2 is a rear perspective view of the clamp, which is improved on the basis of the existing carrier plate 6, and the back structure is the same as the back structure of the existing carrier plate 6; Figure 6 The figure is a front stereoscopic view of the clamp, in which a first positioning rod 11 extending forward is arranged in front of the loading plate 6, the first positioning rod 11 is perpendicular to the loading plate 6, and its rear end is fixedly connected to the loading plate 6, a rotating shaft 12 is vertically installed at the front end of the first positioning rod 11, and a stainless steel fixing plate 13 is vertically rotatably installed on the rotating shaft 12. Specifically, a vertical first through hole 14 (such as Fig.14As shown in the figure, the rotating shaft 12 passes through the first through hole 14 and exposes the threaded connecting section 15, which extends into the first through hole 14. A positioning nut 16 is installed at the threaded connecting section 15, and the positioning nut 16 is rotated downward to clamp the fixing plate 13.

[0032] The specific operation process of the above-mentioned clamp is as follows: first, the fixing plate 13 is taken down, and the fixing plate 13 is heated by a heating platform, and the rectangular seed crystal 23 is glued to the fixing plate 13 with melted paraffin wax, and the fixing plate 13 is installed on the rotating shaft 12 after the whole is cooled and solidified, and then the fixing plate 13 is rotated, as shown in FIG. Figure 7 The figure is a top view of the cutting state after installation and positioning. The rotation angle α in the figure is the cutting angle of the clamping portion 24 of the seed crystal 23. Then, the positioning nut 16 is rotated downward to clamp the fixing plate 13. The entire clamping device moves linearly toward the cutting line 10, gradually cutting out the inclined surface part of the clamping portion 24. Figure 8 As shown, the fixing plate 13 is then rotated to make the fixing plate 13 parallel to the loading plate 6 and fixed, and then cut again; after one side is cut, the fixing plate 13 needs to be removed and heated again, and then fixed with paraffin wax, and the other side is cut.

[0033] Example 2

[0034] like Fig. 9 The fixture shown is a variation of Example 1, in which the rotating shaft 12 at the front end of the first positioning rod 11 extends downward, the fixing plate 13 is rotatably mounted below the first positioning rod 11, and the positioning nut 16 is mounted on the threaded connection section 15 at the lower end of the rotating shaft 12. In Examples 1 and 2, before cutting the seed crystal 23, it is best to mark the cutting reference line on the seed crystal 23 with a pen, and then adjust and align the cutting line 10 for cutting.

[0035] Example 3

[0036] like Fig.10 , 11 As shown, an angle rotation reference plate 17 is further added to the fixture of Example 1. The reference plate 17 is a protractor in the shape of a semicircular ring plate. The center point of the reference plate 17 is located at the rotation axis 12. The arc midpoint of the reference plate 17 is fixed to the lower surface of the rear end of the first positioning rod 11; Fig.11 As shown, the 0° scale of the reference plate 17 is located on the center line of the reference plate 17, the reference range is 90° clockwise, and the reference range is 90° counterclockwise.

[0037] Example 4

[0038] The rotation angle in implementation 3 needs to be observed by a person, which is not fast and accurate enough; for this reason, the inventors have also designed a structure for more quickly and directly observing the rotation angle of the fixed plate 13; Fig.12 , 13As shown, the first positioning rod 11 adopts a digital protractor, such as a digital protractor of the brand Jingluda and the model of 225 degrees. The digital protractor is composed of two relatively rotatable rulers, on which an angle display screen 20 is arranged. The angle generated after the two rulers are separated will be directly displayed on the display screen; the structure of the digital protractor specifically applied in this fixture is as follows Fig.12 , 13 As shown, the digital protractor includes a fixed scale plate 18, a rotating scale plate 19 and an angle display screen 20; the fixed scale plate 18 is perpendicular to the carrier plate 6, and its rear end is fixedly connected to the carrier plate 6, the rotating scale plate 19 is installed above the fixed scale plate 18, and the fixed plate 13 is installed above the rotating scale plate 19, and the front ends of the three are vertically connected together by a rotating shaft 12; Fig.13 As shown, two extending fixed connecting plates 21 are provided at the edges of the contact surfaces of the rotating ruler plate 19 and the fixed plate 13, and a bolt is passed through the through holes of the two fixed connecting plates 21 to detachably connect the rotating ruler plate 19 and the fixed plate 13 together; in this way, the rotating ruler plate 19 and the fixed plate 13 rotate synchronously, and the angle display screen 20 needs to be set to a position that is convenient for observation, such as Fig.12 As shown, in this embodiment, the angle display screen 20 is arranged on the left side of the fixed scale plate 18.

[0039] Although the present invention has been described in detail with reference to the aforementioned examples, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
