A resistance and a silicon rectification are arranged in series on the charging loop circuit of the charging and discharging system, and two sets of discharging preionization devices which are connected in parallel are arranged on the discharge loop circuit. The utility model has quick speed of mark printing and large output energy, satisfying the high speed online marking requirement; the mark printing machine is widely used for mark printing for a plurality of classes nonmetallic materials, providing the identification with high distinguishability and easy discrimination.
Description
Technical field
The utility model relates to a kind of rapid laser identification imprinter.
Background technology
General laser marking machine is connecting a resistance in the charge circuit of its charge and discharge device, and this resistance is at least more than 20 kilo-ohms, otherwise the power supply in the circuit is breakdown easily.Because the existence of this resistance has prolonged the time that discharges and recharges, thereby caused the mark speed of laser marking machine slower, be difficult to adapt to modern high speed and work online.Simultaneously, because a cover discharge preionization device only is set in the general charge and discharge device, preionization electric capacity has caused the low shortcoming of mark machine output energy between 40-60.Because mark requires to have higher energy on materials such as some plastics, glass, the too low meeting of energy causes laser marking machine that be marked material and position are had selectivity, or the mark dim pattern is unclear, allows the people be difficult to identification, so cause the range of application of laser marking machine not extensive.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of rapid laser identification imprinter is provided.
In order to achieve the above object, the utility model has adopted following measure: a kind of rapid laser identification imprinter comprises: power supply, signal spring system, charge-discharge system, laser resonator system, cold and hot exchange system, inflating and exhausting system, outer light path device and annular seal space; Charge-discharge system is made of charge circuit and discharge loop; Be connected with power supply, electric capacity, inductance on the charge circuit; Described electric capacity constitutes discharge loop with gap discharge switch, discharge preionization device again; Be serially connected with reactor and silicon rectifier on the charge circuit.
Discharge preionization device of the present utility model is provided with two covers, and the connected mode between the two cover discharge preionization devices is in parallel.
Owing to substituted resistance with reactor and silicon rectifier in the charge circuit of charge-discharge system of the present utility model, drop to by 20 kilo-ohms of resistance and to go to zero, shortened the time of discharging and recharging greatly, improved mark speed, satisfy the requirement of high speed on-line marking, can run on the production line to long-time continuous stable.Simultaneously, because the utility model is provided with two cover discharge preionization devices, preionization electric capacity quantity can reach 80-160, two covering devices are worked simultaneously, the laser beam energy of output is big, can reach 18 joules/more than the pulse, make the mark function apply to the mark of multiclass nonmetallic materials and the sign that the resolution ratio height can be provided, be easy to discern more widely.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the circuit theory diagrams of the utility model charge-discharge system.
The specific embodiment
As shown in fig. 1, the utility model annular seal space 20 inside are provided with cold-heat-exchanging exchange system 14; Cold-heat-exchanging exchange system 14 and the outer cold and hot exchange system of refrigeration system 13 formations of annular seal space.Annular seal space 20 tail ends are provided with completely reflecting mirror 12, and the outgoing mirror of front end is a partially reflecting mirror 16, and the place ahead of partially reflecting mirror 16 is a focus lamp 17, and the fixed-site of the workpiece 18 that is printed is in the place ahead of focus lamp; Total reflective mirror 12 constitutes optical resonator with partially reflecting mirror 16, and the focus lamp 17 and the workpiece 18 that is marked constitute outer light path device; Optical resonator constitutes laserresonator 15 jointly with outer light path device.The annular seal space bottom is provided with gas stirring device 8.Be provided with air extractor 7 and aerating device 11 outside the annular seal space 20, both constitute inflating and exhausting system.In annular seal space 20, also be provided with discharge preionization device 21 between total reflective mirror 12 and the partially reflecting mirror 16, this device is made of battery lead plate 10 and preionization electric capacity 9, and discharge preionization device 7 is provided with two covers, and is parallel with one another between two covers.Discharge preionization device 21 constitutes charge-discharge system of the present utility model with power supply 1, reactor 2, silicon rectifier 3, gap discharge switch 5, the electric capacity 6 of annular seal space 20 outsides.
As shown in Figure 2, charge-discharge system of the present utility model is made of charge circuit and discharge loop, and charge circuit is mainly formed by power supply 1, reactor 2, silicon rectifier 3, electric capacity 6, inductance 20 serial connections.Discharge loop is formed by electric capacity 6, gap discharge switch 5, discharge preionization device 21 serial connections.Gap discharge switch 5 also is connected with triggering signal 4.
The course of work of the present utility model: provide high-voltage DC power supply by power supply 1, charge with 8 pairs of electric capacity 6 two ends of inductance by reactor 2, silicon rectifier 3.After electric capacity 6 chargings finished, triggering signal 4 was given gap discharge switch 5 signals, makes the gap conducting, electric capacity 6 discharges.At this moment, because electric capacity 6 is high pressure pulse discharges, the impedance phase of inductance 8 is to the circuit infinity, and therefore, electric current is by preionization electric capacity 9 and battery lead plate 10, thereby excitation reaches the purpose of excited gas by the gas that inflating and exhausting system charges into.
