Sample sending and taking manipulator for industrial analyzer

Abstract

The invention discloses a sample sending and taking manipulator for an industrial analyzer, which comprises a crucible support assembly and a crucible clamp assembly, wherein the crucible support assembly comprises a crucible support shaft and a lifting motion drive assembly and a horizontal motion drive assembly which are positioned in the bottom of the crucible support shaft; the crucible clamp assembly comprises a crucible clamp and a crucible clamp support shaft; the crucible support shaft comprises a rotating section and a fixed section from top to bottom; and the crucible clamp assembly also comprises a rotating assembly for enabling the crucible clamp support shaft and the rotating section to rotate together. The invention has the advantages of simple and compact structure, low cost, convenience in assembly, capability of improving complete machine performance, and the like.

Description

technical field [0001] The invention mainly relates to the field of element analysis equipment, in particular to an industrial analyzer. Background technique [0002] A traditional industrial analyzer mainly includes a weighing device 15, a combustion device 16, and a sampling device 17 (manipulator), such as figure 1 As shown, when the above structure is in use, the movement of the crucible from the weighing plate of the sample weighing device 15 to the burning plate of the burning device 16, and then to the weighing plate after the experiment is completed through the horizontal movement of the manipulator at three points and one line. In order to prevent the crucible from falling during the movement of the manipulator, a crucible holding device 18 is added to the manipulator. However, the general crucible holding device 18 is fixed and arranged on one side of the manipulator, but during the movement, the crucible holding device 18 will run into the weighing pan of the sam...

Problems solved by technology

However, the general crucible holding device 18 is fixed and arranged on one side of the manipulator, but in the course of movement, the crucible holding device 18 can run into the weighing pan of the sample weighing device 15 or the combustion disk of the burning device 16; To prevent the crucible holding device 18 from touching the weighing pan or the combustion disk, the crucible holding device 18 is generally arranged side by side with the manipulator, and is not arranged on the movement route of the manipulator, but this increases the size of the crucible holding device. 18 and the overall width of the manipulator cause the corresponding opening of the combustion device 16 to send samples to become larger, but the larger opening causes the loss of temperature in the combustion device 16, increases energy consumption, and reduces measurement accuracy
