Description

Technical Field

[0001] The invention belongs to the technical field of diamond micropowder processing, and in particular relates to an automated ultrasonic screening process for diamond micropowder. Background Art

[0002] With the development of information technology and optoelectronic technology, the demand for semiconductor materials and LED substrate materials is increasing. Grinding plays an irreplaceable role as a method of efficiently flattening the surface of wafers in the processing of semiconductor materials and LED substrate materials. Diamond micro-powder abrasive particles have excellent properties such as high hardness, high strength, good thermal stability and good chemical stability.

[0003] However, most of the steps in traditional screening processes are complicated, and the effects of auxiliary screening and screening stratification are poor. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides an automated ultrasonic screening process for diamond micropowder, which has the characteristics of fewer steps, simple operation, and good auxiliary screening and screening stratification effects.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: an automated ultrasonic screening process for diamond micropowder, comprising raw material crushing, subjecting the diamond raw material to a crusher;

[0006] Raw material crushing: The crushed micro powder is simply screened with a mesh size of 5mm. The screened micro powder is collected and the micro powder that does not meet the standard is put into the crusher for further crushing;

[0007] Feeding mechanism: The micro powder after simple screening will be connected to the feeding mechanism, which can perform adjustable feeding processing on the material. The feeding mechanism is connected to the multi-stage screening equipment and feeds it;

[0008] Multi-stage screening: With the help of ultrasonic vibration, the materials inside the multi-layer filter are assisted in screening, and the minimum filter is 1mm. Qualified materials will be collected and stored, and unqualified materials will continue to be added to the multi-stage screening device for cyclic screening.

[0009] Preferably, the feeding mechanism is an auger structure.

[0010] Preferably, a supporting buffer structure is provided inside the multi-stage screening.

[0011] Preferably, the simple screening is performed by stirring to assist the screening.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention can preliminarily limit the generated micropowder by setting a simple screening to ensure the efficiency of subsequent screening. By setting an adjustable feeding mechanism, the feeding rate can be reasonably controlled, which can effectively prevent the material from being out of control and reduce the situation of material accumulation and blockage. Through multi-stage screening, the material can be separated into layers, and the material that has not been screened can be repeatedly screened. At the same time, materials of different sizes can be collected in layers. BRIEF DESCRIPTION OF THE DRAWINGS
