Abstract

The utility model discloses a printing machine with prevent slow -witted device, include: printing machine body, photoelectric sensor, timing controller and alarm, be equipped with the steel mesh on the printing machine body, after photoelectric sensor sensed the steel mesh, timing controller began the count, printing machine body beginning printing work, and when timing controller counted the setting value, the contact triggering signal of printing machine timing relay made the body stop printing work, and timing controller can send a signal for the alarm simultaneously, and the alarm begins to report to the police, photoelectric sensor, timing controller and alarm all with printing machine body electric connection. In this way, the utility model discloses printing machine with prevent slow -witted device solved present printing machine set for the defect of not preventing staying, to the steel mesh carry on regular effective cleanness, effectively improved the printing quality, improved the qualification rate of printing.

Description

A kind of printing machine with anti-misoperation device

Technical field

The utility model relates to printing mechanism field, particularly relates to a kind of printing machine with anti-misoperation device.

Background technology

The software design patterns not fool proof of existing printing machine, after press printing amount reaches setting sheet number, screen can be pointed out and need to clean steel mesh, but, as long as operating personnel press continuation button, printing machine just can continue to produce, therefore, present stage does not have anti-misoperation device due to printing machine, and steel mesh can be caused long-time not manual clean, part IC hole plug, thus cause the PCB of batch printing bad.

Utility model content

The technical problem that the utility model mainly solves is to provide the higher printing machine with anti-misoperation device of a kind of qualification rate that regularly clean steel mesh, printing.

For solving the problems of the technologies described above, the utility model provides a kind of printing machine with anti-misoperation device, comprise: printing machine body, photoelectric sensor, timing controller and alarm, described printing machine body is provided with steel mesh, after described photoelectric sensor senses steel mesh, timing controller starts counting, printing machine body starts presswork, when timing controller count down to setting value, the contact triggering signal of printing machine electrotimer makes body stop presswork, timing controller can send a signal to alarm simultaneously, alarm starts to report to the police, described photoelectric sensor, timing controller and alarm are all electrically connected with printing machine body.

In the utility model preferred embodiment, described photoelectric sensor is NPN photoelectric sensor.

The beneficial effects of the utility model are: the utility model with the printing machine of anti-misoperation device solve not fool proof in the setting of existing printing machine defect, regular effectively clean, the qualification rate that effectively improves press quality, improve printing is carried out to steel mesh.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:

Fig. 1 is the structural representation of printing machine one preferred embodiment with anti-misoperation device of the present utility model.

Detailed description of the invention

Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1,

A kind of printing machine with anti-misoperation device, comprise: printing machine body 1, photoelectric sensor 2, timing controller 3 and alarm 4, described photoelectric sensor 2, timing controller 3 and alarm 4 are all electrically connected with printing machine body 1, described printing machine body 1 is provided with steel mesh, after described photoelectric sensor 2 senses steel mesh, timing controller 3 starts counting, printing machine body 1 starts presswork, when timing controller 3 count down to setting value, printing machine body 1 stops presswork, timing controller 3 can send a signal to alarm 4, alarm 4 starts to report to the police, now, operating personnel must take out steel mesh, otherwise alarm 4 can be in alarm condition always, only have after waiting for the regular hour, steel mesh reloads on printing machine body 1 by operating personnel, alarm 4 is eliminated and is reported to the police, after photoelectric sensor 2 senses steel mesh, printing machine body 1 starts presswork, timing controller 3 starts counting, always reciprocal, this ensures that there printing machine body 1 after printing some, this quantity is the setting value of printing machine body 1, operating personnel must take out steel mesh, and steel mesh is cleaned, after steel mesh after cleaning is put on printing machine body 1 again, printing machine body 1 just can start presswork again, effective like this cleaning on time that ensure that steel mesh, prevent the blocking in steel mesh IC hole, the PCB significantly reducing batch prints fraction defective, improve the qualification rate of PCB printing.

In addition, described photoelectric sensor 2 is NPN photoelectric sensor.

Be different from prior art, the utility model passes through to arrange anti-misoperation device on printing machine body with the printing machine of anti-misoperation device, described anti-misoperation device is by photoelectric sensor, timing controller and alarm composition, effectively ensure that printing machine starts printing when photoelectric sensor senses steel mesh, printing number is strictly counted by timing controller, after being printed onto some, alarm sends warning, now, operating personnel must take off steel mesh and clean, and after the steel mesh after cleaning is loaded onto, printing machine could start again to print, thus ensure that the cleaning on time of steel mesh, increase substantially the qualification rate of printing.

Be different from prior art, the utility model with the printing machine of anti-misoperation device solve not fool proof in the setting of existing printing machine defect, regular effectively clean, the qualification rate that effectively improves press quality, improve printing is carried out to steel mesh.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.

Claims
