Full-function osmotic pump controlled-release tablet laser-beam drilling machine

Abstract

The invention relates to a full-function osmotic pump controlled-release tablet laser-beam drilling machine. The device comprises a two-orbit tablet vibration disk feeder, a double-layer flat belt type conveyer, a color discrimination sensor, a drilling positioning sensor, a laser, a high-velocity scanning vibration mirror, a computer and a vision detection removing system. By adopting the structural design of the two-orbit tablet vibration disk feeder and the double-layer flat belt type conveyer, controlled-release tablets are increased from original 5-10 tablets to 15-30 tablets per second through, the failure rate of the continuous operation of the controlled-release tablets is lowered, and the defects of poor adaptive capacity and easy material buckling of a rotating disk type mechanical sequencing structure are overcome; all operation is carried out in a stable and continuous operating state, and therefore, accurate positioning and good drilling consistency are achieved; by adopting the vision detection removing system, accurate removal is achieved, and therefore, the defects of incomplete removal and excess removal which are generated by adopting a pneumatic device are prevented; and the vision detection removing system detects the controlled-release tablets one by one and discriminates and removes imporous and polyporous tablets and tablets with unqualified apertures and pore sites, and therefore, the requirements of the GMP (Good Manufacturing Practice) of industrial production are met.

Description

technical field [0001] The invention relates to a laser punching device for tablets, in particular to a laser punching machine for controlled-release tablets with a full-function osmotic pump. Background technique [0002] In recent years, the structure of laser drilling machines for osmotic pump controlled-release tablets has been continuously improved on the premise of ensuring drug efficacy, but existing laser drilling machines for osmotic pump controlled-release tablets with different structures still have shortcomings and deficiencies, for example: 1. The mechanical structure of the rotary table with small holes is used for sorting. The disadvantage of this structure is that it is easy to jam the material, and the failure rate is high. The feeding and discharging are carried out by the weight of the tablet, and high-speed production cannot be realized; 2.

[0002] In recent years, the structure of laser drilling machines for osmotic pump controlled-release tablets has been continuously improved on the premise of ensuring drug efficacy, but existing laser drilling machines for osmotic pump controlled-release tablets with different structures still have shortcomings and deficiencies, for example: 1. The mechanical structure of the rotary table with small holes is used for sorting. The disadvantage of this structure is that it is easy to jam the material, and the failure rate is high. The feeding and discharging are carried out by the weight of the tablet, and high-speed production cannot be realized; 2. For the double-chamber osmotic pump controlled release tablet Tablet reflux device processing, this processing method will reduce the tablet conveying speed by 50%; 3. The double-track tablet vibrating plate feeder is generally designed with a single track, and a color recognition sensor and a pneumatic rejecting device are installed. According to the probability, there is about 1 / 2. The dual-chamber controlled-release tablets will be ejected back to the vibrating plate feeder, reducing the feeding speed by 50%. When the pneumatic rejecting device blows a controlled-release tablet, there will be a certain probability to drive the front and rear controlled-release tablets, so the actual feeding The speed is reduced even more. In addition, the controlled-release tablet is in an unstable state of vibration on the tablet vibrating plate feeder. The disadvantages of "missing picking" and "multiple picking" coexist; 4. The flat belt conveyor is generally designed with a single-layer conveyor belt structure. Multi-purpose; 5. The function is single, and there is generally a lack of on-line inspection of punching quality and removal of unqualified products, or the design of on-line inspection of punching quality and removal of unqualified products is not accurate, which affects production efficiency and cannot ensure product quality
