Abstract

The invention provides a control device of a trace addition instrument. A start signal is received through an input module (11), a setting module (12) sets grinding liquid addition amount information, a calculation module (13) then calculates the number of circles by which a peristaltic pump (22) needs to rotate according to the addition amount information, pulse information which needs to be sent out is calculated according to the number of the circles, an output module (14) sends pulses to the peristaltic pump (22) according to the pulse information so as to make the peristaltic pump (22) rotate, and therefore grinding liquid in a grinding liquid tank (21) is thrown out. Meanwhile, the invention further provides the trace addition instrument with the control device (10). By means of the control device, the throwing amount and the throwing time of polishing liquid can be accurately controlled, and the polishing effect can be conveniently improved.

Description

technical field

[0001] The invention relates to a control device for a micro-dosing instrument. Background technique

[0002] Polishing is the last link in gem processing. Only after polishing can any gemstone achieve crystal clear and dazzling effects, resulting in a pleasing aesthetic feeling. The process of gem polishing is to use abrasives (polishing powder) on polishing discs of various materials to grind and polish the gemstones that have been shaped. The polishing effect is related to many factors such as the material of the polishing disc, the operating state of the machine, the polishing technique, the composition of the polishing powder and the polishing liquid, and the feeding situation. Among them, the input of polishing fluid (grinding fluid) is a factor that is difficult to control. At present, in the gem polishing process, the injection of polishing liquid is generally controlled by manual operation and the time of injection. There are cases where the amount...
