Along with the fast development of electronics and information industry, the chip components and parts demand rises significantly.Surface mount device (claiming chip components and parts again) industry increases rapidly just in the world, promotes electronic technology and complete machine to develop to short and small frivolous, integrated, intellectuality and multifunction direction.
One important procedure in the chip electronic component manufacturing process is exactly the serigraphy of interior electrode, existing screen printing device is mainly based on single station, and the main feature of slice component is the superimposition printing of interior electrode, and requirement relative position of electrode in lamination process will accurately be controlled, for example, the lamination procedure for the chip electromagnetic interface filter relates to capacitance electrode, the multilayer of inductance electrode and earth terminal is repeated print, and existing single station equipment just is difficult to guarantee the precision problem of printing.
In printing multilayer during electrode, existing method mainly is to adopt the method that repeats to change screen printing net plate, resetting, this method makes screen process press have location poor repeatability, low, the not high shortcoming of efficient of printing precision inevitably, make the properties of product uniformity and the poor stability that make, therefore existing equipment is restricted during the electrode member superimposition printing in multilayer, has hindered the development of chip type element.
At present, except that the method that adopts single station plane positioning above-mentioned, also has the double screen process press of installing side by side at home and abroad.When carrying out the printing of multi-layered electrode, normally buy many single station printing machines, each printing machine is finished a kind of printing work of electrode, so not only can cause the increase of production cost, also can cause production efficiency low, though and the double screen process press can solve the low problem of repetitive positioning accuracy, but will make equipment be difficult to satisfy the requirement of technology during the electrode more than printing is two-layer, two stations are arranged side by side simultaneously, the floor space of equipment is increased, the operation number increases, and production cost increases.So how to solve the superimposition printing of electrode in the multilayer, accomplish not only economy but also conveniently be the screen process press problem demanding prompt solution.
(3) summary of the invention:
For overcome exist in the prior art cause locating poor repeatability, printing precision is low, efficient is not high deficiency owing to repeating to change screen printing net plate, resetting, the present invention proposes a kind of multistation flat surface screen printing machine that carries out superimposition printing.
The present invention mainly is made up of location locking mechanism, silk-screen mechanism, guiding mechanism and driving mechanism, and wherein: location locking mechanism is made up of stopping means, locking device, rotating shaft; Guiding mechanism is made up of stop screw, frame, guide pillar.
Technical characterictic of the present invention is the multilayer screen printing net plate vertically successively is sleeved in the rotating shaft, and screen printing net plate can be horizontally rotated and fix by location locking mechanism around the shaft.The substrate orientation that storing is had the die sheet is on working plate, and this working plate can vertically move.During use, each layer screen printing net plate behind the calibration location, realized continuous superimposition printing by the height of adjusting diaphragm.
The present invention has adopted stopping means, locking device, can not change to guarantee the relative position of multi-layered net plate in printing process, thereby the location between the electrode is more accurate in making.
Because the technical measures that the present invention takes realize the multi-sheet printed operation machine that combines in, and have solved the low problem of the existing repeatable accuracy of slice component multi-electrode superimposition printing effectively.
