Abstract

The disclosure discloses a frame component, which includes a frame with a positioning slot in an inner edge thereof, a fabrication strip with grooves, and a plurality of support pieces; where the fabrication strip is detachably arranged in the positioning slot, and the plurality of support pieces are fixed in the grooves to form a support plane for supporting a mask.

First claim

The invention claimed is:

1. A frame component, comprising:
a frame with a positioning slot in an inner edge thereof;
a fabrication strip with grooves; and
a plurality of support pieces;
wherein:
the fabrication strip is detachably arranged in the positioning slot;
the plurality of support pieces are fixed in the grooves to form a support plane for supporting a mask;
a depth of each of the grooves is not less than the thickness of each of the plurality of support pieces;
the fabrication strip is arranged to form a welding plane for welding the mask; and
the fabrication strip comprises a plurality of fabrication sheets adhered into the positioning slot, and an interval between every two adjacent fabrication sheets of the plurality of fabrication sheets constitutes one of the grooves.

2. The frame component according to claim 1 , wherein the fabrication strip is welded into the positioning slot.

3. The frame component according to claim 2 , wherein the fabrication strip is welded into the positioning slot by:
welding a fabrication strip in an encircled shape into the positioning slot; wherein the fabrication strip in the encircled shape is fit closely onto an inner edge of the positioning slot along an internal contour of the positioning slot; and
cutting the fabrication strip in the encircled shape via a laser cutting process at positions where the grooves need to be arranged, to obtain the grooves.

4. The frame component according to claim 2 ,
wherein the plurality of fabrication sheets are fit closely onto an inner edge of the positioning slot, and are arranged spaced apart from each other along an internal contour of the positioning slot.

5. The frame component according to claim 1 , wherein the fabrication strip is adhered into the positioning slot.

6. The frame component according to claim 5 , wherein the fabrication strip is adhered into the positioning slot by:
adhering a fabrication strip in an encircled shape into the positioning slot; wherein the fabrication strip in the encircled shape is fit closely onto an inner edge of the positioning slot along an internal contour of the positioning slot; and
cutting the fabrication strip in the encircled shape via a laser cutting process at positions where the grooves need to be arranged, to obtain the grooves.

7. The frame component according to claim 5 ,
wherein the plurality of fabrication sheets are fit closely onto an inner edge of the positioning slot, and are arranged spaced apart from each other along an internal contour of the positioning slot.

8. The frame component according to claim 1 , wherein the fabrication strip is made of a metal material.

9. The frame component according to claim 8 , wherein the metal material comprises an Invar36 or a SUS304.

10. The frame component according to claim 1 , wherein a thickness of the fabrication strip is not less than a thickness of each of the plurality of support pieces.

11. The frame component according to claim 1 , wherein a thickness of the fabrication strip is approximately 100 μm.

12. The frame component according to claim 1 , wherein a depth of the positioning slot is greater than a thickness of the fabrication strip.

13. The frame component according to claim 12 , wherein a difference between the depth of the positioning slot and the thickness of the fabrication strip ranges from 10 μm to 20 μm.

14. The frame component according to claim 1 , wherein the frame has a rectangular-ring shape.

15. The frame component according to claim 14 , wherein the plurality of support pieces comprise a plurality of first support pieces and a plurality of second support pieces, fixed in the grooves;
wherein the plurality of first support pieces and the plurality of second support pieces are parallel to two vertically intersected sides of the frame, respectively; the plurality of second support pieces cooperate with each other to form the support plane; and the plurality of first support pieces are configured to divide the support plane into a plurality of blocking areas.

16. The frame component according to claim 15 , wherein the plurality of first support pieces are cover sheets; and the cover sheets are welded into the grooves.

17. The frame component according to claim 15 , wherein the plurality of first support pieces are cover sheets; and the cover sheets are adhered into the grooves.

18. The frame component according to claim 15 , wherein the plurality of second support pieces are howling sheets; and the howling sheets are welded into the grooves.

19. The frame component according to claim 15 , wherein the plurality of second support pieces are howling sheets; and the howling sheets are adhered into the grooves.

20. The frame component according to claim 1 , wherein the fabrication strip and the plurality of support pieces are formed integrally.
