Description

Technical Field

[0001] The invention relates to the field of micro-nano imprinting equipment, and in particular to a magnetic template cover jig. Background Art

[0002] The micro-nano imprinting process involves a template, but the template itself has a service life and needs to be replaced at certain intervals. The template itself is also limited in a specific fixture, and the fixture needs to limit the template very well. However, the template itself is a very thin and fragile item, so the replacement of the existing template often requires caution and the operation is not very convenient. Summary of the invention

[0003] The problem to be solved by the present invention is to provide a magnetic template cover jig, which utilizes magnetic attraction to absorb and lift out a pressure ring, thereby making room for replacing the template, and the replacement of the template is efficient and safe.

[0004] In order to solve the above problems, the present invention provides a magnetic template cover jig. In order to achieve the above purpose, the technical solution adopted by the present invention to solve its technical problems is:

[0005] A magnetic template cover jig comprises: a base plate, the upper surface of which is provided with a bearing surface which matches the vertical projection of the template, the outer contour of the bearing surface is in the shape of a major arc, and a concave annular groove is provided around the bearing surface; a pressure ring which matches the vertical projection of the annular groove, and the pressure ring and the annular groove are detachably assembled; a cover plate, comprising a cover ring which has adsorption force on the upper surface of the pressure ring, a transparent plate is provided in the middle of the cover ring, and a convex handle is also provided on the cover ring; the pressure ring and the cover ring are made of ferromagnetic materials.

[0006] The beneficial effect of adopting the above technical solution is: when the template needs to be replaced, the personnel grasp the cover plate, and use the cover plate to absorb and lift the pressure ring. Because the cover ring of the cover plate is made of magnetic material, after being fitted with the upper surface of the pressure ring, the pressure ring can be directly lifted out of the annular groove. There is no need to consider setting a notch on the annular groove to facilitate the opening of the pressure ring, and the pressure ring and the annular groove can be tightly assembled together. At the same time, when the cover plate lifts the pressure ring, the pressure ring itself basically always remains horizontal. In the original way of prying the pressure ring, the pressure ring itself is easy to be at an angle with the horizontal plane, and it is easy to get stuck with the bearing surface, damaging the bearing surface. The role of the transparent plate is to facilitate visual observation by personnel and prevent debris from falling onto the template. The inner contour of the pressure ring restricts it from rotating in the annular groove, ensuring the limitation of the template. In addition to the vertical upward freedom of the template, the replacement of the template is efficient and safe.

[0007] As a further improvement of the present invention, there are two handles, a line connecting the two handles passes through the centroid of the cover ring, and the tops of the handles are provided with bulged portions.

[0008] The beneficial effects of adopting the above technical solution are: the arrangement position of the handle ensures that the cover plate is not easily tilted on the fingers of the person due to its own weight, and the enlarged part of the handle prevents the cover plate from slipping out of the hands of the person.

[0009] As a further improvement of the present invention, the lower surface of the transparent plate is higher than the lower surface of the cover ring, and the transparent plate is made of acrylic material.

[0010] The beneficial effects of adopting the above technical solution are: ensuring that the transparent plate will not damage the template, and the transparent acrylic material is easy to obtain and is light in weight.

[0011] As a further improvement of the present invention, the thickness of the pressure ring is not less than the depth of the annular groove.

[0012] The beneficial effect of adopting the above technical solution is: ensuring that the pressure ring is not lower than the bearing surface, and the template can be limited in its own degree of freedom by the pressure ring.

[0013] As a further improvement of the present invention, the outer contour of the pressure ring, the outer contour of the cover ring, and the inner contour of the cover ring are all circular, the outer contour radius of the cover ring is smaller than the outer contour radius of the pressure ring, and the radius corresponding to the major arc of the bearing surface is smaller than the inner contour radius of the cover ring.

[0014] The beneficial effect of adopting the above technical solution is: ensuring that the size of the cover ring is just inside the pressure ring, and all the lower surfaces of the cover ring are in contact with the pressure ring, and do not contact with the transparent plate.

[0015] As a further improvement of the present invention, the bottom of the annular groove is provided with a plurality of first fixing holes. When the pressure ring is assembled with the annular groove, the pressure ring is provided with a third fixing hole docking with the first fixing hole. The third fixing hole passes through the upper and lower surfaces of the pressure ring, and the first fixing hole and the third fixing hole are connected by screws.

[0016] The beneficial effect of adopting the above technical solution is that the first fixing hole and the third fixing hole can assemble and fix the pressure ring and the bottom plate within a period of time.

[0017] As a further improvement of the present invention, the outer contour of the bottom plate is rectangular, and a plurality of vertical second fixing holes are provided between the outer contour of the annular groove and the outer contour of the bottom plate.

[0018] The beneficial effect of adopting the above technical solution is that the corners of the rectangle provide positions for the second fixing holes, and the second fixing holes can fix the bottom plate to other workbenches.

[0019] As a further improvement of the present invention, the bearing surface is provided with concave-convex wrinkles, forming a plurality of concentric major arcs of different sizes.

[0020] The beneficial effect of adopting the above technical solution is that it can provide uniform support for the template and prevent the smooth flat surface from having a suction effect on the template, thereby increasing the difficulty of replacing the template.

[0021] As a further improvement of the present invention, a convex mirror is provided on the transparent plate.

[0022] The beneficial effect of adopting the above technical solution is that the convex mirror can easily act as a magnifying glass, and the state of the template can be observed while the pressure ring is moving. BRIEF DESCRIPTION OF THE DRAWINGS
