Description

Technical Field

[0001] The utility model relates to the field of coating fixtures, in particular to a detachable coating fixture. Background Art

[0002] As Figure 1 Shown is a hanging plate of a traditional sputtering coating machine. When coating a lens product, a high-temperature tape needs to be entirely pasted on the hanging plate for fixation first, and then the product is adhered to the adhesive surface of the high-temperature tape and put into the coating machine for coating. After coating is completed, the product is removed from the high-temperature tape, and then the entire high-temperature tape is torn off, and a new high-temperature tape is replaced for the next round of production.

[0003] The traditional coating fixture has the following disadvantages: 1. When coating with a high-temperature tape, under the bombardment of the ion source energy during the coating process, the performance of the colloid changes, and the colloid transfers to the product to form residual glue, resulting in poor appearance of the product. Even for some film systems with high film-forming temperatures, the colloid fails, causing the product to fall off and be scrapped; 2. At the same time, the colloid is an organic substance. Under the bombardment of energy and high-temperature baking, gas substances will volatilize, and the volatilized gas will affect the vacuum stability in the coating chamber, thereby affecting the optical curve stability of the product; 3. Due to the large size of the entire coating hanging plate, it is inconvenient to disassemble and clean, and abnormal purchases such as fixture film debris points often occur. In addition, the high-temperature coating tape is a disposable material and has a high price. Continuous replacement is required during production, resulting in high costs.

After coating, the film debris on the surface of the coating fixture can be cleaned in time, improving the cleanliness of the coating fixture and thus the appearance quality of the product.

[0013] (2) In the present utility model, the product is fixed by the coating fixture, and the coating fixture is fixed on the coated hollow hanging plate by nuts and then put into the sputtering coating machine for coating together. The use of high-temperature tape is cancelled, solving the problems of residual glue and product detachment caused by high-temperature tape coating, and avoiding the problem of tape outgassing, improving the coating stability and the optical curve stability.

[0014] (3) The coating jig of the present utility model can be recycled, with a service life of 3 - 5 years. The high-price disposable high-temperature tape is cancelled, and the overall production cost is significantly reduced, improving the market competitiveness of the product.
