3D watchcase inner chamber coating fixture and plate picking base matched with same in use

Abstract

The invention provides a 3D watchcase inner chamber coating fixture and a plate picking base matched with the same in use. The fixture comprises a fixture base plate and a fixture cover plate; the fixture base plate is provided with a plurality of product positioning grooves matched with to-be-machined products in size; the bottom surface of each product positioning groove is provided with a push-out through hole for pushing each product out of the corresponding product positioning groove; the fixture cover plate is installed at the opening sides of the product positioning grooves of the fixture base plate; each to-be-machined product is compressed inside the corresponding product positioning groove; the fixture cover plate is provided with an opening at a position corresponding to each product positioning groove; and the inner diameter of the opening is not larger than that of the opening of a machining surface of the inner chamber of the corresponding to-be-machined product. The fixture provided by the invention is light and convenient and has the advantages of not damaging the exterior of a ceramic watchcase, providing convenience for taking and putting the products, preventing pollution and defective scratching of a coating formed at the inner chamber, and increasing the yield.

Description

technical field [0001] The invention relates to a fixture used for film coating on the inner cavity of a 3D watch case and a supporting chip-taking base thereof. Background technique [0002] With the development of science and technology, the functions of electronic products such as watches, mobile phones, and computers are becoming more and more diverse. In order to meet consumers' demand for the function and appearance of electronic products, the design of products is becoming more and more complex, especially the complex inner cavity structure of the 3D ceramic case, and in response to its functional requirements, it is necessary to coat the complex inner cavity structure And ensure the integrity of the entire appearance surface. At present, the existing technology is to use metal fixtures with double product positioning grooves to meet the technical requirements of 3D watch case inner cavity coating, but the metal fixtures have the following disadvantages: (1) The fixt...

AI Technical Summary

Problems solved by technology

At present, the existing technology is to use metal fixtures with double product positioning grooves to meet the technical requirements of 3D watch case inner cavity coating, but the metal fixtures have the following disadvantages: (1) The fixture is heavy and laborious to operate, And it causes a lot of load pressure on the machine motor; (2) It is inconvenient to take the product, you need to directly contact the inner cavity of the watch case with your fingers, and it is easy to introduce dirt and scratches on the inner cavity film layer; (3) When taking and placing the product , the friction between ceramics and metals is easy to produce dot-shaped or linear black marks, and the appearance surface needs to be reworked; (4) It is inconvenient to maintain the fixture, and it is difficult to clean and maintain it by acid-base or sandblasting.
