Description

Technical Field

[0001] The utility model relates to the technical field of prism processing, in particular to a micro-prism coating jig. Background Art

[0002] Prisms are polyhedrons made of transparent materials, often glass, and are widely used in optical instruments and camera components. In the optical coating industry, prisms often require surface coatings, such as high-transmittance or high-reflection coatings, to improve their optical performance.

[0003] When coating the surface of a prism, a coating fixture is a commonly used auxiliary tool. The prism is clamped by the coating fixture, and then the coating fixture is fixed to the coating umbrella. Then, the coating umbrella and the coating machine work together to coat the surface of the prism.

[0004] The current coating fixtures need to consider the stacking problem between coating fixtures to facilitate one-time stacking and easy removal. The coating fixtures are made thicker to achieve stacking after the products are placed. However, due to the thick thickness, it is inconvenient to take them, and the product placement slot will be expanded, causing the product to be unstable after placement, and the product shaking can easily cause damage to the product. Utility Model Content

[0005] In order to solve the above technical problems, the utility model designs a microprism coating fixture.

[0006] The utility model adopts the following technical solutions:

[0007] A microprismatic coating jig includes a jig body with a row of evenly spaced product placement slots for microprismatic products. The product placement slots have coating openings at their bottoms, and end support partitions are formed at both ends of the product placement slots to support the ends of the microprismatic products. A pair of mounting threaded holes are formed on either side of the jig body, and support columns are threadedly connected to the mounting threaded holes. When the microprismatic coating jigs carrying products are stacked, the support columns are supported between the stacked microprismatic coating jigs.

[0008] Preferably, the corners at both ends of the product placement slot are provided with take-out ports to facilitate product extraction.

[0009] Preferably, the sides of the product placement slot are provided with necking portions at both ends, and the width of the necking portions is set to match the width of the micro-prism product, so that the product can be placed firmly and taken out more conveniently.

[0010] Preferably, the back of the fixture body is provided with a circle of stepped clamping parts for docking with the notches on the coated umbrella stand, so as to facilitate the stable installation of the fixture body.

[0011] Preferably, the two sides of the back of the fixture body are provided with hand-held parts to facilitate the extraction of the fixture body.

[0012] Preferably, the fixture body is made of stainless steel plate through CNC carving.

[0013] Preferably, the processing accuracy of the CNC precision carving is controlled within ±0.05mm.

[0014] Preferably, the edge of the jig body is free of burrs to prevent the product from being scratched when unloading.

[0015] The beneficial effects of the present invention are as follows: (1) A pair of mounting threaded holes are provided on both sides of the fixture body of the present invention, and support columns are threadedly connected to the mounting threaded holes, which facilitates the stacking of micro-prismatic coating fixtures and is convenient in advance; (2) There are respectively openings for taking out products at the corners at both ends of the product placement slot. This facilitates the extraction of products. The side of the product placement slot is provided with a necking portion at both ends, and the width of the necking portion is set to match the width of the micro-prismatic product. This facilitates the stable placement of products and makes extraction more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0020] Example: Figure 1 and Figure 2 As shown, a microprismatic coating jig includes a jig body 1, on which a row of product placement slots 2 for placing microprismatic products are evenly arranged, a coating port 3 is provided at the bottom of the product placement slots, and end support partitions 4 are formed at both ends of the product placement slots to support the two ends of the microprismatic products. A pair of mounting threaded holes 7 are respectively provided on both sides of the jig body, and support columns (not shown in the figure) are threadedly connected to the mounting threaded holes.

[0021] The product placement slot has two corners with access ports 5 to facilitate product extraction. The sides of the product placement slot have necking portions 6 at both ends, with the width of the necking portions being set to match the width of the microprism product.

[0022] The back of the fixture body is provided with a circle of stepped clamping parts 9 for docking with the notches on the coated umbrella stand. Hand grips 8 are provided on both sides of the back of the fixture body.

[0023] The fixture body is made of stainless steel plate through CNC engraving. The CNC engraving process has a machining accuracy of ±0.05mm. The fixture body has no burrs on the edges.

[0024] This new jig features a pair of threaded mounting holes on either side of the jig body. These holes are threaded with support posts, facilitating stacking of microprismatic coating jigs. Access ports are located at the corners of the product placement slot, facilitating product extraction. The sides of the slot feature tapered openings, each designed to match the width of the microprismatic product. This ensures secure product placement and facilitates easy extraction.

[0025] The embodiment described above is only a preferred solution of the present invention and does not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
