The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] Example 1

[0029] Please refer to Figure 1 A schematic diagram of a processing mold for a quartz substrate provided in this application includes:

[0030] A mold body 1, wherein the mold body 1 is arranged below a quartz substrate 12, and the center of the mold body 1 is coaxial with the center of the quartz substrate 12; the quartz substrate 12 is provided with a plurality of mounting holes, and the mounting holes are used to mount a quartz cylinder; a plurality of first extensions 2 and second extensions 3 are alternately arranged in the circumferential direction of the mold body 1, the first extension 2 is provided with at least one first through hole 4, and the second extension 3 is provided with at least one first blind hole 5;

[0031] The mold body 1 has a first state and a second state, and the mold body 1 switches between the first state and the second state; when the mold body 1 is in the first state, the first through hole 4 is aligned with the mounting hole, the quartz cylinder is inserted into the mounting hole and the first through hole 4, and the quartz cylinder is virtually connected to the quartz substrate 12; when the mold body 1 is in the second state, the first blind hole 5 is aligned with the mounting hole, and after the quartz cylinder is inserted into the first blind hole 5, the quartz cylinder is welded to the quartz substrate 12.

[0032] Specifically, the mold body 1 is made of graphite, and graphite can help disperse and conduct heat, which results in that the heat required for welding is insufficient to form a good weld; therefore, after the initial positioning is completed, the quartz substrate 12 and the quartz cylinder are firstly connected, that is, the quartz cylinder and the quartz substrate 12 are spot welded to preliminarily fix the quartz cylinder and the quartz substrate 12, and then the mold body 1 is switched to the second state, at which time each of the quartz cylinders extends into the first blind hole 5, and at this time, the quartz cylinder abuts against the bottom wall of the first blind hole 5, and at this time, the quartz substrate 12 does not fit the mold body 1, so as to avoid heat dissipation during the welding process and ensure the dimensional accuracy of the quartz cylinder during the welding process;

[0033] Specifically, the mold body 1 is alternately provided with a plurality of first extensions 2 and second extensions 3 in the circumferential direction, the first extension 2 is provided with at least one first through hole 4, and the second extension 3 is provided with at least one first blind hole 5; the mold body 1 is rotated to switch between the first state and the second state;

[0034] Specifically, Figure 2 and Figure 3 As shown, in this embodiment, according to the actual position of the mounting hole on the quartz substrate 12, two first through holes 4 are provided on the first extension portion 2, and two first blind holes 5 are provided on the corresponding second extension portion 3;

[0035] Specifically, since a plurality of first extension parts 2 and second extension parts 3 are alternately arranged in the circumferential direction of the mold body 1, the hollow space between the first extension parts 2 and the second extension parts 3 is utilized to facilitate welding operations on the welding points using a welding gun;

[0036] Working principle: When it is necessary to weld a quartz cylinder on the quartz substrate 12, firstly, the quartz substrate 12 and the center of the mold body 1 are coaxially placed, at which time the mold body 1 is in the first state, the first through hole 4 is aligned one by one with the mounting hole on the quartz substrate 12, the quartz cylinder is inserted into the mounting hole and the first through hole 4, and the quartz cylinder is virtually connected to the quartz substrate 12, that is, the quartz cylinder is spot welded to the quartz substrate 12, so as to achieve the purpose of positioning the quartz cylinder and the quartz substrate 12; then, the quartz substrate 12 on which the quartz cylinder is installed is lifted, and the mold body 1 is rotated so that the quartz cylinder is virtually connected to the quartz substrate 12; The mold body 1 is in the second state, at this time, the first blind hole 5 is aligned with the mounting hole on the quartz substrate 12 one by one, the quartz cylinder extends into the first blind hole 5, and abuts against the bottom wall of the first blind hole 5; at this time, the quartz substrate 12 and the mold body 1 are not in contact, and the quartz substrate 12 and the quartz cylinder are welded; through the above structure, the same processing mold is used to perform the false connection and welding operations on the quartz substrate 12 and the quartz cylinder, and the mold body 1 is also used to position the quartz cylinder during the welding process to prevent the size from changing after welding, thereby improving the accuracy of the welding size.

[0037] In some embodiments, the angles between each first extension portion 2 and the second extension portion 3 are equal, and the first through holes 4 on the first extension portion 2 correspond one-to-one to the first blind holes 5 on the adjacent second extension portions.

[0038] Specifically, Figure 2 As shown, the angle between each first extension part 2 and the second extension part 3 is equal, and the first through hole 4 on the first extension part 2 corresponds to the first blind hole 5 on the adjacent second extension part one by one; after the quartz cylinder and the quartz substrate 12 are connected, it is only necessary to rotate the mold body 1 according to the first angle, and the first angle is the angle between the adjacent first extension part 2 and the second extension part 3, and each of the quartz cylinders will enter the first blind hole 5 on the second extension part 3 adjacent to the first extension part 2;

[0039] Specifically, in some embodiments, a plurality of first through holes 4 are provided on the first extension portion 2, and the plurality of first through holes 4 are sequentially distributed outward from the center of the mold body 1; at this time, a plurality of first blind holes 5 are correspondingly provided on the second extension portion 3, and the plurality of first blind holes 5 are sequentially distributed outward from the center of the mold body 1; and the distance between each of the first through holes 4 from the center to the outside is equal to the distance between each of the first blind holes 5 from the center to the outside.

[0040] In some embodiments, when the mold body 1 is in the second state, a graphite pad 7 is disposed between the mold body 1 and the quartz substrate 12 .

[0041] Specifically, during the welding process, the quartz substrate 12 is not in contact with the mold body 1, and the quartz substrate 12 is supported solely by the quartz cylinder, resulting in unstable support; therefore, when the mold body 1 is in the second state, a graphite pad 7 is arranged between the mold body 1 and the quartz substrate 12, and the graphite pad 7 is arranged away from the welding point to enhance the stability of the quartz substrate 12 and avoid heat dissipation during the welding process; in this embodiment, a plurality of graphite pads 7 are arranged.

[0042] In some embodiments, at least one positioning hole is provided on the quartz substrate 12, and a second through hole 6 is provided on the mold body 1 corresponding to the positioning hole.

[0045] In some embodiments, the mold body 1 is further comprised of a driving component configured to drive the mold body 1 to switch between the first state and the second state.

[0046] Specifically, Figure 4 As shown, the processing mold also includes a driving component, which is connected to the mold body 1 and is used to drive the mold body 1 to switch between a first state and a second state.

[0051] A first driving motor 8 , wherein a driving end of the first driving motor 8 is connected to the second gear 10 , and the first driving motor 8 is used to drive the second gear 10 to rotate.

[0053] In some embodiments, the mold body 1 and the second gear 10 are detachably connected.

[0054] Specifically, the mold body 1 and the second gear 10 are detachably connected to facilitate replacement of the mold body 1; in the present embodiment, the mold body 1 and the second gear 10 are connected by screws to achieve detachable connection between the mold body 1 and the second gear 10.

[0055] Workflow: When it is necessary to weld a quartz cylinder on the quartz substrate 12, firstly, the quartz substrate 12 and the center of the mold body 1 are coaxially placed, the positioning hole is aligned with the second through hole 6, and the quartz substrate 12 is fixed to the mold body 1 by bolts.
