The inner side of the slot rods 201 is provided with a slot 203 for fixing the silicon wafer.

[0032] In order to achieve compatible positioning of different types of quartz boats in the quartz boat production line and improve the efficiency of changeover, the utility model provides a quick changeover positioning tool 100 for quartz boat processing. Figures 1 to 7 The positioning tool 100 includes a base 10, a first positioning plate 20, a second positioning plate 30 and a positioning assembly 40. The first positioning plate 20 and the second positioning plate 30 are relatively arranged on the base 10. Four groups of positioning assemblies 40 are arranged on the first positioning plate 20 and the second positioning plate 30. The four groups of positioning assemblies 40 on each positioning plate are arranged in a structure of two groups on the top and two groups on the bottom. Among them, the two groups of positioning assemblies 40 on each positioning plate are symmetrically arranged, the two groups of positioning assemblies 40 on the bottom are symmetrically arranged, and the positioning assemblies on the two positioning plates are also symmetrically arranged. In this way, the four groups of positioning assemblies 40 on the two positioning plates are used to support and position the two upper slot rods 201 of the quartz boat 200, and the four groups of positioning assemblies 40 on the bottom of the two positioning plates are used to support and position the two lower slot rods 201 of the quartz boat 200.

[0033] Specifically, refer to Figures 4 to 6 The positioning assembly 40 includes a mounting block 41, a support rod 42, a stopper 43, a toothing 44, a first set screw 45 and a second set screw 46. The mounting block 41 is arranged on the corresponding positioning plate. The support rod 42 and the toothing 44 are respectively adjustably arranged on the mounting block 41 along the first direction X. The stopper 43 is arranged on the support rod 42. A supporting groove is formed between the support rod 42, the stopper 43 and the mounting block 41 to support the groove rod 201. The outer end of the toothing 44 has a tooth portion 441, and the tooth portion 441 extends into the supporting groove. The first set screw 45 and the second set screw 46 are respectively arranged on the mounting block 41 along the second direction Y, and the first set screw 45 is used to tighten the support rod 42, and the second set screw 46 is used to tighten the toothing 44. It should be understood that the first direction X is Figure 1 The left and right directions of the positioning tool 100 are shown, and the second direction Y is Figure 1 The front-to-back direction of the positioning tool 100 shown in the figure, the second direction Y is perpendicular to the first direction X; the stopper 43 is arranged at the outer end of the support rod 42, that is, the end of the support rod 42 away from the positioning plate along the first direction X, and the outer end of the inserting tooth 44 refers to the end of the inserting tooth 44 away from the positioning plate along the first direction X; the structure of the tooth portion 441 matches the structure of the slot 203, so that it can be just inserted into the slot 203.

[0034] Combination Fig. 9As shown, in application, the slot rod 201 is placed in the supporting slot along the second direction X, and the inserting teeth 44 are adjusted so that the tooth portion 441 is inserted into the appropriate slot 203, so that the quartz boat 200 is supported and fixed by using multiple sets of positioning components 40 to ensure the stability of the quartz boat 200. At the same time, the positions of the supporting rod 42 and the inserting teeth 44 can be adjusted along the first direction X, and after adjustment, they can be fixed respectively by using set screws, so that they can match quartz boats 200 of different widths, thereby enhancing compatibility.

[0035] Reference Figure 2 and Figure 3 In some embodiments, the base 10 includes a bottom plate 11, a connecting shaft 12 and a connecting plate 13. The bottom plate 11 is provided with a first shaft hole 111, and the connecting plate 13 is provided with a second shaft hole 131. The structures of the first shaft hole 111 and the second shaft hole 131 respectively match the structures of the connecting shaft 12. The connecting shaft 12 is fixed in the second shaft hole 131, and the lower end of the connecting shaft 12 penetrates into the first shaft hole 111. Two positioning plates are arranged on the connecting plate 13.

[0036] Furthermore, the connecting plate 13 is fixed to the bottom plate 11 by a first screw (not shown in the figure, existing screw products can be used according to needs), and the bottom plate 11 is provided with a plurality of first fixing holes 112, and the plurality of first fixing holes 112 are arranged at intervals along the circumference of the first shaft hole 111, and the connecting plate 13 is correspondingly provided with an arc-shaped first adjustment hole 132, and the first adjustment hole 132 extends along the circumference of the second shaft hole 131, and the first screw passes through the first adjustment hole 132 and is connected with the corresponding first fixing hole 112. In this way, by adjusting the relative angle between the connecting plate 13 and the bottom plate 11, the direction of the two positioning plates can be changed, and the direction of the slot bar 201 can also be changed. The reason for such arrangement is that in some types of quartz boats, there is a non-right angle between the slot rod 201 and the end plate 202, that is, the slot rod 201 is not perpendicular to the end plate 202, for example, the angle between the slot rod 201 and the end plate 202 is 88°. In the welding positioning of these quartz boats, it is necessary to make the slot rod 201 and the end plate 202 in a non-vertical fixed state; in some other processes, it is necessary to adjust the angle of the quartz boat. For the above-mentioned various situations, if different positioning devices are replaced in the production line according to different types of quartz boats, it will lead to reduced production efficiency, inconvenient operation and high manufacturing cost. Therefore, the utility model adjusts the angle of the slot rod 201 by adjusting the angle of the connecting plate 13, which can be adapted to the processing technology of quartz boats with different angles, thereby improving the applicability of the positioning tool 100.

[0041] Among them, the support assembly 50 can be provided with multiple groups, such as Figure 1 As shown, in one embodiment, two groups of support components 50 are disposed between the first positioning plate 20 and the second positioning plate 30 , and the two groups of support components 50 are disposed in parallel to enhance the structural stability of the positioning tool 100 .

[0042] See also Figures 4 to 6In some embodiments, the positioning assembly 40 further includes a paddle 47 and a stop ring 48.
