Description

technical field

[0001] The invention relates to the field of precision instruments, in particular to an automatic proportioning device for glue and powder for LED packaging. Background technique

[0002] In the fields of test analysis, trace element addition, fine chemical industry and LED, etc., the accuracy of ingredients is required to be very high. Generally, it needs to reach ±10mg, and the requirement for higher occasions needs to reach ±0.1mg.

[0003] At present, in the occasions where precise proportioning and high-precision ingredients are required, the manual proportioning method is basically adopted, and the accuracy and repeatability are determined manually by the operator. In terms of precision, it is difficult to guarantee the precision in the range of 0.1 mg due to the heavy repetitive labor intensity of operators. In terms of repeatability, due to the inconsistent operation level of each operator and the characteristics of various raw materials, there will ...
