Description

Laser drilling machine system

The invention relates to a medical special laser drilling machine system, in particular to a drilling operation of a circular and cylindrical medicine tablet which can be universally used in a certain size range.

In the manufacturing process, for tablets that need to be gradually released for a long time (for example, drugs for heart disease), it is necessary to punch holes in one end of the tablet to make the tablets in the body. When affected by body fluids and temperature, the non-perforated end material inside the tablet expands, and the powder can be pushed out gradually from the hole of the other end face (as shown in Fig. 13), and this is played on the tablet. The hole process needs to be done quickly by a laser puncher.

However, a laser puncher can only use one set of machine components. For different shape of the tablet, such as: graphic or cylindrical, you need to purchase two sets of lasers. Please refer to Figure 13 for general release. The medicine ingots 90, 91 can be roughly formed into a circular or cylindrical type. When laser drilling is required for the sustained release medicine, the round medicine ingot 90 is on one side of the two large sides 901, 902. The punching is performed, and the cylindrical ingot 91 is perforated on the cylindrical end surface 911, 912. The positions of the two kinds of ingots 90, 91 are greatly different, including the calculation method of the conveying unit and the laser drilling distance. The direction of the punching is different, so the ingot with a large difference in shape is replaced by a set of laser punching machines, which is too wasteful in cost and is one of the disadvantages of the conventional use.

Furthermore, depending on the size of the ingot 90, 91, it varies from 6 mm to 12 mm. Generally, multiple laser drilling machines are required to separately transport and punch holes, but in this way, multiple laser drilling machines will be purchased. Therefore, the laser drilling machine must have a complete set of designs, which can be adapted to various types. The tablet is ready for use with a simple configuration, making it the most economical laser puncher.

The main object of the present invention comprises at least: a feeding system, a two-group feeding mechanism, a ring conveyor transmission system, a continuous conveyor transmission system, and a related detecting and punching system; The combination can be universally used in a certain size range. For the punching of commonly used circular and cylindrical medicine ingots, it is necessary to replace a set of laser drilling machines for different shapes or sizes of the ingots, and the cost is more economical.
