In view of this, it is necessary to a kind of automatization screen printer, the problems such as the labor intensity of solution silk screen printing is high, production efficiency is low, production cost is high are provided.
The present invention provides a kind of screen printer, and it is connected with drying unit and exposure device, for forming specific pattern or word on workpiece.This screen printer includes: a frame, and this frame is used for placing multiple workpiece, and this frame includes multiple silk printing screens that correspondence is covered on each workpiece;One eindruckwerk, this mechanism includes a scraper, a cylinder and the driving means being positioned at above frame, and wherein driving means is used for position and the angle driving scraper with drum movement and can regulate scraper above-mentioned silk printing screen relative with cylinder;And a spray equipment, it is positioned at the side of frame and for the roller spray photoresists of eindruckwerk and ink.
The screen printer of the present invention can print specific pattern or word at surface of the work automatically, and then solves to there is the problems such as labor intensity is high, production efficiency is low, production cost is high in existing manual operation.
Detailed description of the invention
With reference to Fig. 1 and Fig. 2, screen printer 1 includes frame 10, eindruckwerk 20, spray equipment 30.This frame 10 is placed with some workpiece (not shown) and includes the some silk printing screens 11 being covered on workpiece.This eindruckwerk 20 and spray equipment 30 are for forming specific pattern or word by this silk printing screen 11 in surface of the work printing.
Frame 10 includes a supporting surface 12 and is positioned at the guide plate 13 above supporting surface 12, and wherein this supporting surface 12 is provided with some resettlement sections 14.Each resettlement section 14 offers a host cavity 140 of accommodating workpiece.Each silk printing screen 11 is rotationally connected with supporting surface 12, and is positioned near a resettlement section 14, it is possible to turn to cover the position of the host cavity 140 of resettlement section 14.
Described eindruckwerk 20 includes driving means 21, two fixed part 23 being arranged on guide plate 13 and by a drive link 22 of driving means 21 power transmission to fixed plate 23, and wherein this two fixed plate 23 is individually secured to the both sides of drive link 22.Eindruckwerk 20 also includes cylinder 24 and the scraper 25 being fixedly installed between this two fixed plate 23, its intermediate roll 24 for by photoresists and Ink Application in silk printing screen 11.When this driving means 21 works, it can drive eindruckwerk 20 to slide along above-mentioned guide plate 13 respectively, and this driving means 21 can also drive drive link 22 to swing, and then the position of regulation cylinder 24 silk printing screen 11 relative with scraper 25.
In the lump with reference to Fig. 3, described spray equipment 30 includes housing 31, loading plate 32 between above-mentioned supporting surface 12 and guide plate 13 and the upper some containers 33 being fixed on this loading plate 32 and for the motor 34 driving loading plate 32 to rotate.Housing 31 includes an opening cavity 310 towards above-mentioned eindruckwerk 20, and wherein loading plate 32 and container 33 are positioned at this cavity 310.Described container 33 is used for accommodating photoresists or ink, and it can spray photoresists or ink when by extruding from the external world automatically.Motor 34 is positioned at above housing 31 and includes an output shaft 340, and wherein this output shaft 340 is through the roof of above-mentioned housing 31, and the end of this output shaft 340 is fixedly attached on loading plate 32.
Above-mentioned driving means 21 and motor 34 are commonly connected to a control device 40, and this control device 40 is used for controlling driving means 21 and motor 34 works.During work, control device 40 and control in driving means 21 works and drives cylinder 24 dislocation spray equipment 30 and extrude the container 33 equipped with photoresists, and then make photoresists be sprayed into cylinder 24 surface.Control device 40 control driving means 21 drive drive link 22 to be rocked to cylinder 21 can be with silk printing screen 11 contact position of frame 10 move along guide plate 13 and then photoresists are coated on silk printing screen 11.Photoresists on above-mentioned silk printing screen 11 are carried out baking process and exposure technology so that on silk printing screen 11, form the mesh-portion stopping that ink passes through.
Control device 40 controls motor 34 work and goes to drive loading plate 32 to rotate so that the container 33 equipped with ink can contact with cylinder 24 respectively.With above-mentioned identical method, ink can be coated on silk printing screen 11 by cylinder 24.
Finally, control device 40 to control driving means 21 work and make drive link 22 be rocked to scraper 25 phase in a certain angle with silk printing screen 11 to support position, and drive scraper 25 to move along guide plate 13 ink is pressed into the mesh of silk printing screen 11, and then form specific pattern or word at surface of the work.In the middle of present embodiment, the angle between scraper 25 and silk printing screen 11 is about 75 °, is beneficial to scraper 25 and ink was scraped the mesh of silk printing screen 11 equably.
In the middle of present embodiment, this screen printer 1 also includes being arranged at frame 10 exposure device 50 relative with spray equipment 30, and wherein this exposure device 50 is for being exposed technique to the photoresists of above-mentioned silk printing screen 11.Owing to photoresists are not before being oven-dried, photoperceptivity is more weak, but after drying, photoperceptivity then can be very sensitive.Exposure device is placed in described frame 10, is conducive to being exposed operation immediately after silk printing screen 11 is dried.
Although being illustrated and described the preferred embodiment of the present invention, but those skilled in the art will appreciate that, may be made that various different changes and improvements, and these are all without departing from the true scope of the present invention.Therefore, it is intended that the invention is not limited in the disclosed detailed description of the invention as the optimal mode realized contemplated by the present invention, in all embodiments that the present invention includes have the protection domain of appended claims.
