Deformation polishing process and polishing clamp for 2.5D window screen

Abstract

The invention discloses a deformation polishing process and a polishing clamp for a 2.5D window screen. The process comprises the following steps: stacking products in a manner that the 2.5D surfaces and 2D surfaces of the products are aligned to one another respectively in sequence; putting the stacked products into the clamp and positioning the clamp in the positioning groove of a fixed base; fixing the fixed base to the surface of a polishing machine table for polishing. The process has the advantages of simple steps, easy operation, high production capacity, high efficiency and high yield.

Description

Technical field [0001] The invention relates to a 2.5D window screen special-shaped polishing process and a polishing fixture thereof. Background technique [0002] In recent years, the development of window screens has shifted from flat wafers to 2.5D, but because 2.5D special-shaped polishing cannot be polished completely at one time, it needs to be polished at different locations. However, because the existing polishing process is for flat products, the polishing fixture and its The polishing process is based on the polishing idea of ​​flat products. First, the four straight edges of the product need to be clamped four times, then the four bottom edges need to be clamped four times, and finally the four arc edges need to be clamped four times. , A total of twelve times of polishing and twelve times of clamping are required, which makes the process cumbersome and the operation is very inconvenient. At the same time, the operator is prone to unexpected errors in the operation pr...

[0002] In recent years, the development of window screens has shifted from flat sheets to 2.5D, but because 2.5D special-shaped polishing cannot be polished completely at one time, it needs to be polished in different parts. The polishing process follows the polishing idea of ​​flat products. First, the four straight edges of the product need to be clamped four times for polishing, then the four bottom chamfered edges need to be clamped four times for polishing, and finally the four curved edges need to be clamped four times for polishing. , a total of twelve times of polishing and twelve times of clamping are required, which makes the process cumbersome and inconvenient to operate. At the same time, the operator is prone to unpredictable mistakes during the operation, which affects the further processing of the product and the needs of the process. It will lead to the failure of the workpiece processing, resulting in economic losses of the production enterprise
