Description

Technical Field

[0001] The present invention relates to a highly compatible coating fixture and a using method thereof, belonging to the technical field of coating equipment. Background Art

[0002] With the development of society and the progress of technology, coated products are widely used in various fields such as optics, electronics, medical treatment, military, civil use, and education. Among them, optical components such as glass and crystals are important components of optical and laser products, and coating plays an important role in improving the performance of such products.

[0003] Glass and crystal products have the characteristics of multiple sizes and large differences. Most of the current coating fixtures have low compatibility, and one fixture can only meet one or a class of product specifications. For example, a fixture that can hold a product with a diameter of 10 mm cannot be used for a product with a diameter of 30 mm; it can hold circular products but cannot hold prismatic products. After wiping or cleaning, the coated surface of the product often contacts the fixture during the clamping process, resulting in contamination; moreover, the height consistency of the coated surface of the product protruding from the fixture is not good, causing film thickness errors during coating.

[0004] Chinese patent document CN211170871U discloses a vacuum coating fixture, including a base. A support column is movably arranged on the top of the base. A first fixing disk and a second fixing disk are arranged on the outer periphery of the support column, and several groups of the first fixing disk and the second fixing disk are vertically staggered. Fixed rods are fixedly arranged on both sides of the second fixing disk. First fixing teeth are fixedly arranged on the top and bottom edges of the first fixing disk, and second fixing teeth are fixedly arranged on the top and bottom edges of the second fixing disk, and the second fixing teeth and the first fixing teeth are correspondingly arranged. Elastic sheets are fixedly arranged between adjacent groups of the second fixing teeth. Fixed sheets are fixedly arranged on both sides of the second fixing disk, and the fixed rods penetrate through the corresponding fixed sheets. This fixture can fix multiple workpieces at one time, but it cannot hold different types of products and has low compatibility. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a highly compatible coating fixture, which can hold different types of glass and crystal products, has high compatibility, and at the same time ensures the same coating height of the coated surface of the product, improves the coating effect, and effectively avoids contamination of the coated surface of the product.

[0006] The present invention also provides a using method of the above-mentioned highly compatible coating fixture.

[0007] The technical solution of the present invention is as follows:

[0008] A highly compatible coating fixture, comprising a flat plate, a U-shaped frame, an upper V-shaped plate, a lower V-shaped plate, a fixing plate and an auxiliary mechanism. Among them, a dovetail guide rail A is arranged on the flat plate. One end of the dovetail guide rail A is provided with an auxiliary mechanism, and the other end is vertically provided with a U-shaped frame. The fixing plate, the upper V-shaped plate and the lower V-shaped plate are slidably sleeved on the U-shaped frame from top to bottom in sequence.

[0009] Preferably, dovetail guide rails B are symmetrically arranged on one side of the U-shaped frame. The fixing plate, the upper V-shaped plate and the lower V-shaped plate are slidably sleeved on the dovetail guide rails B.

[0010] Further preferably, U-shaped grooves are symmetrically arranged on the other side of the U-shaped frame. A clamping plate is clamped between the U-shaped grooves. When clamping a thick sheet-shaped product, the clamping plates are respectively placed above and below the thick sheet-shaped product to block the film material from returning. When clamping a thin sheet-shaped product, the clamping plates are used as the bearing and clamping parts, so that the device can adapt to different types of products and ensure compatibility.

[0011] Preferably, the clamping plate is a rectangular plate. Convex platforms are arranged on both sides of the rectangular plate. The clamping plate is placed in the U-shaped grooves on both sides of the U-shaped frame through the convex platforms. Steps are arranged on the clamping plate to bear and clamp the thin sheet-shaped product through the steps, ensuring the coating effect of the thin sheet-shaped product.

[0012] Preferably, a V-shaped opening A is arranged on the lower V-shaped plate. A through hole A is arranged at the bottom of the V-shaped opening A. The upper V-shaped plate and the lower V-shaped plate have the same shape. The prismatic product is clamped through the V-shaped opening A. When the prismatic product is clamped, its edges are placed in the through hole A. By arranging the through hole A, damage to the prismatic product is avoided. Not only prismatic products but also round products with a larger thickness can be clamped in the V-shaped opening A.

[0013] Further preferably, at least 1 V-shaped opening A is arranged. The specific quantity can be determined according to actual requirements. By increasing the quantity of the V-shaped opening A, the quantity of clamped products is increased.

[0014] Preferably, a stepped through hole is arranged on the fixing plate. A countersunk head screw is arranged in the stepped through hole. The countersunk head screw is threadedly connected to the upper V-shaped plate. A spring is sleeved on the countersunk head screw. The upper V-shaped plate is connected to the fixing plate through the cooperation of the spring and the countersunk head screw, making the upper V-shaped plate elastic. It can not only avoid directly rigidly pressing and damaging the product, but also elastically clamp the product to prevent the product from falling off or being cracked due to thermal expansion and contraction during coating.

[0015] Preferably, the auxiliary mechanism includes a carrier and a two-dimensional adjustment frame. The two-dimensional adjustment frame is slidably connected to the dovetail guide rail A. A carrier is arranged on the two-dimensional adjustment frame. A V-shaped opening B is arranged on the carrier. A through hole B is arranged at the bottom of the V-shaped opening B. The two-dimensional adjustment frame realizes the height adjustment and horizontal position adjustment of the carrier. The two-dimensional adjustment frame slides on the dovetail guide rail A to realize the horizontal position adjustment of the carrier, thereby realizing the three-dimensional adjustment of the carrier.

[0016] Preferably, L-shaped limiting plates are symmetrically arranged on one side of the flat plate where the U-shaped frame is arranged, and the movement range of the U-shaped frame is limited by the L-shaped limiting plates.

[0017] The usage method of the above-mentioned highly compatible coating fixture for thick sheet products, where the thickness of the thick sheet product is greater than 5 mm and the shape is not limited, is as follows:

[0018] (1) Assemble and place the lower V-shaped plate, the upper V-shaped plate, and the fixing plate into the U-shaped frame in sequence.
