Method of external application medicine patch on-line die cutting

Abstract

The invention relates to laser cutting method, in particular to an on-line laser die-cutting method for an external use medicine paste. The method solves the problem that the current laser cutting speed of the external use medicine paste is slow and can not synchronize with the compounding production line of the external use medicine paste. The on-line die-cutting method of the invention comprises: a phase that the medicine coating base material of the medicine paste is conveyed to the cutting unit ; a phase that the medicine coating base material is sucked tightly by a vacuum chuck; a longitudinal incision cutting phase with 2N intervals at each row ; a phase that the medicine coating base material is continuously transmitted; a judging phase that judges whether the medicine paste reaches the medicine paste sign; a transverse incision cutting phase that is carried out by N intervals at each row if the medicine paste sign reaches,; a sucking releasing phase by the vacuum chuck; and a phase that the cuted-out medicine paste falls into the collecting container. The on-line die-cutting method of the invention has fast cutting speed, can synchronize with the compounding production line of the external use medicine paste, and meet the requirements of the modern mass flow production.

Description

technical field [0001] The invention relates to a laser cutting method, in particular to a laser on-line die-cutting method for external medicine stickers. Background technique [0002] At present, laser technology has been widely used in industrial production, such as laser drilling, laser cutting, and laser welding, which have been used in many industries. [0003] In recent years, laser drilling technology has also been used in pharmaceutical production. For example, the LL-9801 laser drilling machine made by Tsinghua University and Beijing Zhonghui Pharmaceutical Company has been successfully used in Changzhou No. 4 Pharmaceutical Factory in osmotic pump control tablets In addition, laser marking machines, automatic trademark cutting machines, flying shear laser cutting machines, craft gift engraving machines, etc. also form products for supply. [0004] The CO2 laser cutting machine generally used in the die-cutting of medicine stickers includes: a laser that emits a l...

AI Technical Summary

Problems solved by technology

At present, the existing laser marking, cutting, cutting, and engraving machines are all independent completion systems, that is, the laser head works according to the input computer graphics control, and after completing the specified work unit continuously and independently, it turns to the next unit, so the cutting speed Slow, low work efficiency, it is difficult to work continuously on the automated production line, even if the existing online marking machine, it is difficult to synchronize with the assembly line to meet the requirements of highly modernized production
