Accurate sand-blasting processing machine for thinned fragile slabs and machining method

Abstract

The invention discloses an accurate sand-blasting processing machine for thinned fragile slabs and a machining method. The accurate sand-blasting processing machine comprises a primary cyclone separation device, a constant sand feeder, a sand blasting device, an air compressor, a thinned fragile slab conveying device, a sand recycling device and a control device, wherein the primary cyclone separation device is used for separating sand materials and dust from the sand recycling device and feeding the sand materials to the constant sand feeder; the constant sand feeder is used for conveying the sand materials at a constant flow velocity to the sand blasting device; the sand blasting device is used for jetting the sand materials to the thinned fragile slabs; the air compressor is used for supplying compressed air to the sand blasting device; the thinned fragile slab conveying device is used for horizontally conveying the thinned fragile slabs; the sand recycling device is arranged under the thinned fragile slab conveying device and is used for receiving the sand materials and the dust, and the output end of the sand recycling device is communicated with the primary cyclone separation device; and the control device is used for controlling each device to operate. When the accurate sand-blasting processing machine is used for processing the thinned fragile slabs to a plurality of products with specific shapes, the chemical etching is avoided, the environmental protection is realized, the product cost is low, and the production speed is high, and the processing accuracy and product yield are high.

Description

technical field [0001] The invention relates to a sandblasting machine, in particular to a precision sandblasting processing machine and processing method for thin fragile plates; the so-called thin fragile plates refer to glass panels, ceramics with a thickness less than or equal to 10mm, high hardness, and easy to break. Substrates, glass-ceramic products and other materials. Background technique [0002] In the traditional technology, when processing a whole piece of thin and fragile plate into several products with a specific shape (that is, a shape designed according to needs), there are mainly two processing methods, one is chemical etching, and this method is due to serious pollution. 1. It affects health and is rarely used; the second is to use cutting CNC machinery for cutting processing. This method is currently the most mainstream processing method. During the cutting process, due to the vibration of the cutter and uneven force on thin and fragile plates, etc. , ...

[0002] In the traditional technology, when processing a whole piece of thin and fragile plate into several products with specific shapes (that is, shapes designed according to needs), there are mainly two processing methods, one is chemical etching, which due to serious pollution 1. It affects health and is rarely used; the second is to use cutting CNC machinery for cutting processing. This method is currently the most mainstream processing method. During the cutting process, due to the vibration of the cutter and uneven force on thin and fragile plates, etc. , The processing yield rate of thin and fragile plates is generally not high. For example, in the cutting process of the touch screen that is currently popular all over the world, its yield rate is basically only about 50%. waste
