Abstract
The invention discloses a screen frame positioner for screen photosensitive plate making and a rapid and accurate positioning method thereof. The screen frame positioner consists of a conical ejector pin positioning device, a trapezoid ejector pin positioning device, a screen frame equipped with a ladder rod polymer photosensitive film screen, and a fixation frame for positioning the screen frame. The rapid and accurate positioning method includes: a preparation alignment process under a lighting condition and a printing platemaking process under a darkroom condition. With the aid of the screen frame positioned, a complex three-parameter screen frame positioning problem is converted to a positioning problem of three single parameters. Rapid and accurate positioning replaces the time-consuming and laborious screen frame manual positioning that cannot ensure the positioning accuracy.
Description
Technical field
The present invention relates to a kind of screen frame locator of screen cloth photosensitive lithographic and the localization method of fast accurate thereof.
Background technology
Textile industry is pillar industry that national economy is traditional and important people's livelihood industry, in the international competition under Background of Economic Globalization, is again the industry that China has comparative advantages simultaneously.During " 12 ", textile industry faces that developed country is high-end in industrial chain, developing country is at the double competition of industrial chain low side.PRINTED FABRIC accounts for 11% ~ 13% share in global textile, and 58% of PRINTED FABRIC is produced by circular screen printer, and PLATE SCREAM PRINTING is 28%; PLATE SCREAM PRINTING is spent back greatly with it, the large-scale pattern of printability, and registration precision is high, flower type is clear, both be applicable to light, flimsy material (as silk class), be applicable to again thick, heavy fabric (as woollen blanket, towelling coverlet class), in printing in textiles field, occupied a tiny space all the time.
Whether move according to printing table, PLATE SCREAM PRINTING, the present invention only relates to the latter if can be divided into moving top table square screen printing process and the large class of fixed platen square screen printing process two.The technological process of fixed platen PLATE SCREAM PRINTING is made up of preparatory process and revenue stamp process.Preparatory process carries out in two steps: the first step, being arranged on high-molecular photosensitive diaphragm screen net on screen frame moves to the positioner arranging on fixed mount, fixed mount screen frame is positioned, ink-jet printer is drawn as required on light-sensitive surface screen cloth, after photochemical treatment, must be printed on the polymeric membrane screen cloth (flower version) of hollow out decorative pattern: the hollow out decorative pattern region of screen cloth can see through mill base, block the approach of mill base arrival fabric without decorative pattern region because of the existence of polymeric membrane; Second step, is transferred to stamp chassis by the screen frame that high-molecular photosensitive diaphragm screen net is installed.Revenue stamp process also carries out in two steps: the first step, and fabric to be printed sticks on platen and maintains static, and the servomotor of stamp chassis engages by gear with Timing Belt and drives chassis, makes it accurately navigate to corresponding stamp station; Second step, stepper motor drives lifting mechanism to drive screen frame decline to press fabric, repeatedly scraped by the mill base on scraper driven by servomotor scraper, promotion screen cloth again, mill base completes the stamp of a pattern (chromatography) through screen cloth, screen frame lifts, stamp chassis moves a flower and returns, arrives next stamp station, until last the stamp station on stationary platen; The length that refers to stamp chassis institute's impression case on fabric " spent back " in the technical term of printing technology.Flat screen printing machine is according to the chromatography requirement of fabric impressing pattern, conventionally needs the configuration chromatography screen cloth of tens different hollow out decorative patterns " several or "; Once complete whole revenue stamp processes of a chromatography, just change the screen cloth of next different patterns and the mill base of different colours carries out next round stamp; Until complete the stamp of last different patterns (chromatography) screen cloth; The technical term " registration precision " of printing technology refers to that different chromatography screen clothes arrive same printer's bit position precision, also claim repetitive positioning accuracy.
Improving " registration precision " is the basis of production high-quality PRINTED FABRIC." registration precision " not only with chassis positioning precision in revenue stamp process about (consulting the patent of invention " the stationary platen flat screen printing machine based on pattern of double controlling " of this Ke Questions group, application number 201210116129.X); And positioning precision during with preparatory process screen cloth (flower version) photosensitive lithographic is relevant.In PLATE SCREAM PRINTING process, each point of PRINTED FABRIC needs successively corresponding from the point of " several or tens different hollow out decorative pattern chromatography screen clothes ", and when stamp, the technique ideal value of each screen cloth point X, Y, Z parameter should be constant; One of key technology that supports " technique ideal value should be constant " is exactly the screen frame location technology that high-molecular photosensitive diaphragm screen net is installed, and is called for short screen frame location technology.
The screen frame positioning precision of existing screen cloth photosensitive lithographic relies on stamp skilled worker's experience and technical ability completely, the screen frame location when method that adopts range estimation to proofread completes screen cloth photosensitive lithographic; And there is intrinsic uncertainty, randomness in manual operations.The screen frame location of screen cloth photosensitive lithographic relates to the adjustment of screen frame X, Y, tri-parameters of Z, in view of there is the fact intercoupling between three parameters, causes manual check and correction time and effort consuming, the positioning precision of screen frame location to be difficult to be guaranteed; In addition, the operating process of screen cloth photosensitive lithographic need be carried out in darkroom, causes complete more barely satisfactory with the manual positioning precision of stamp skilled worker experience and technical ability; At present, the defect ware causing because of the not good enough reason of screen cloth photosensitive lithographic screen frame positioning precision happens occasionally.Up to now, the research of screen frame location is still located space state, is urgently filled up when screen cloth photosensitive lithographic.The screen frame of the present invention during by screen cloth photosensitive lithographic located three parameter problems and is converted into 3 one-parameter location, by the location screen frame of two dedicated positioning devices and servicing unit, fast accurate.
