Storing and picking device and method for sample plates

Abstract

The invention provides a storing and picking device for sample plates. The storing and picking device comprises a box body, a sample plate grabbing assembly, a sample plate stacking mechanism and a lifting mechanism, wherein the sample plate grabbing assembly and the sample plate stacking mechanism are located inside the box body and are sequentially arranged from top to bottom, the sample plates are stacked on the sample plate stacking mechanism, and the lifting mechanism drives the sample plate grabbing assembly to be vertically lifted for grabbing and lifting the sample plates. According to the storing and picking device for the sample plates, the lifting mechanism drives the sample plate grabbing assembly to be vertically lifted, one sample plate is lifted each time, and therefore the load in the lifting process of a motor is lowered, and the failure rate of the motor is lowered. Furthermore, a sample plate rejecting mechanism capable of picking the sample plates and rejecting the sample plates simultaneously is arranged additionally, and therefore the sample plates can be swept. According to the storing and picking device for the sample plates, the storing and picking function and the sweeping function are integrated, the occupied space of equipment is reduced, and the size of the equipment is reduced. In addition, the invention provides a storing and picking method for the sample plates.

Description

technical field [0001] The invention relates to the fields of collection, sample preparation and analysis of material samples, in particular to a sample disk access device and a sample disk access method. Background technique [0002] In the fields of chemical production and energy engineering, the collection, sample preparation and analysis of material samples are essential links. Taking the coal industry as an example, the chemical composition of coal is composed of organic hydrocarbons and inorganic substances, among which the moisture in coal is the most likely to change component, and the moisture in coal is the most basic indicator for evaluating the economic value of coal. Changes in moisture in coal will cause changes in the content or calorific value of other components, which will have a certain impact on the quality inspection, measurement, acceptance, and management of coal. Accurate determination of moisture in coal is of great significance to power production m...
