[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1:

[0029] like Figures 1 to 4 As shown, the present invention provides a photolithography positioning device for circular materials. The corner block 1 is an L-shaped aluminum alloy component with a centrally symmetrical structure. The corner block 1 comprises a horizontal plate 11 and a vertical plate 12, which are perpendicular to each other. The horizontal plate 11 and the vertical plate 12 intersect at one end, creating a positioning area between the horizontal and vertical plates 11 and 12 for placing the circular material 5.

[0030] A transverse sliding rod 21 is detachably mounted on the transverse plate 11 and is parallel to the transverse plate 11. A longitudinal positioning rod 31 is arranged perpendicular to the transverse sliding rod 21. The outer end of the longitudinal positioning rod 31 slides onto the transverse sliding rod 21 and is positioned by a second positioning bolt 42. The inner end of the longitudinal positioning rod 31 extends into the positioning area, where it rests against the round material 5 to ensure alignment in the Y direction. A scale mark is provided on the transverse sliding rod 21 to confirm the position of the longitudinal positioning rod 31 in the X direction.

[0031] Similarly, the longitudinal slide rod 22 is detachably mounted on the longitudinal plate 12, and the longitudinal slide rod 22 is parallel to the longitudinal plate 12. The transverse positioning rod 32 is arranged perpendicular to the longitudinal slide rod 22. The outer end of the transverse positioning rod 32 is slidingly mounted on the longitudinal slide rod 22 and is positioned by another second positioning bolt 42. The inner end of the transverse positioning rod 32 extends to the positioning area and is used to abut against the circular material 5 to realize the alignment of the circular material 5 in the X direction. A scale is provided on the longitudinal slide rod 22 to confirm the position of the transverse positioning rod 32 in the Y direction.

[0032] As shown in Figures 1 to 5 , in use, the positions of the longitudinal positioning rod 31 and the transverse positioning rod 32 in the photolithography positioning device are adjusted according to the size of the circular material 5. Then the photolithography positioning device is placed on the worktable of the photolithography machine at a specified position, and the vacuum suction device is turned on to adsorb the photolithography positioning device. The circular material 5 is placed in the positioning area, and the inner ends of the longitudinal positioning rod 31 and the transverse positioning rod 32 abut against the periphery of the circular material 5, and the extension lines of the longitudinal positioning rod 31 and the transverse positioning rod 32 pass through the center of the circular material 5. Then the vacuum suction device is turned off, and the photolithography positioning device is removed.

[0033] The photolithography positioning device for circular material provided by the embodiment is used for the centering positioning operation of the photolithography machine on the circular material, and the positioning accuracy of the circular material is greatly improved. At the same time, the convenience of operation is also improved, and the subsequent manual fine-tuning time is greatly reduced, thereby improving the photolithography efficiency.

[0034] Embodiment two:

[0035] On the basis of the above-mentioned embodiment one, as shown in Figures 1 to 4 , the structure of the longitudinal positioning rod 31 is opposite to that of the transverse positioning rod 32. The longitudinal positioning rod 31 is taken as an example for description in the embodiment.

[0036] A plurality of pairs of positioning holes 13 are provided on the surface of the transverse plate 11. Two positioning holes 13 in each pair are arranged transversely, and the lengths of the positioning holes 13 in each pair from the positioning area are different. By selecting appropriate positioning holes 13, different sizes of circular materials 5 can be adapted. Threaded holes are provided at the two ends of the transverse slide rod 21, and the first positioning bolt 41 is mounted in the threaded holes. The first positioning bolts 41 at the two ends are threadedly connected in one pair of positioning holes 13, thereby fixing the transverse slide rod 21.

[0037] The outer end of the longitudinal positioning rod 31 has a "U"-shaped sliding sleeve 311, which is invertedly buckled on the transverse slide rod 21 and can slide transversely along the transverse slide rod 21. The outer end of the sliding sleeve 311 is threadedly connected with the second positioning bolt 42, and the inner end of the second positioning bolt 42 abuts against one side of the transverse slide rod 21. By loosening the second positioning bolt 42, the position of the longitudinal positioning rod 31 can be adjusted transversely. Then, by tightening the second positioning bolt 42, the relative fixation of the longitudinal positioning rod 31 and the transverse slide rod 21 is realized.

[0038] In the embodiment, a plurality of positioning holes 13 are arranged on the surface of the horizontal plate 11, and appropriate positioning holes are selected to adapt to circular materials of different sizes; the horizontal slide rod 21 and the vertical slide rod 22 are both fixed on the corner block 1 through the first positioning bolt 41, which facilitates disassembly and reinstallation according to needs, and enhances the flexibility and adaptability of the device, so that the device can be applied to circular materials of different sizes, and the adjustment cost and time cost when replacing materials of different sizes are reduced.

[0039] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
