Abstract
The invention provides a screen printing device, comprising a carrying substrate, a screen and an image positioning device; the carrying substrate comprises a carrying surface provided with at least one positioning hole; each positioning hole is used for carrying and positioning a material to be printed; the gap between each positioning hole and the corresponding material to be printed is smaller than 0.1mm; the screen is provided with at least one printing pattern and forms at least one mark. Each printing pattern corresponds to one positioning hole; the image positioning device is used for shooting an image of the screen and adjusting the position of the screen till the at least one mark is positioned at the preset position of the image, so the at least one printing pattern is enabled to be aligned with the at least one positioning hole. Due to such arrangement, the precision of the screen printing device can be controlled within +/-0.1mm, and the precision is improved compared with the existing screen printing.
Description
Technical field
The present invention relates to screen printing technology, particularly a kind of screen press.
Background technology
The advantages such as cost is little owing to having for screen printing, speed fast, easy debugging are used widely.At present, screen printing is used to again printing optical element to add light shaded areas on optical element.Yet the precision of screen printing often cannot meet the required precision of optical element.
Summary of the invention
In view of this, be necessary to provide a kind of high-precision screen press.
, it comprises a bearing substrate, a web plate and an image positioning apparatus.This bearing substrate comprises a loading end, and this loading end offers at least one locating hole.Each locating hole is for carrying, locate a material to be printed.Each locating hole is less than 0.1mm with the gap between corresponding material to be printed.This web plate offers at least one print pattern, and is formed with at least one mark.Each print pattern is corresponding with a locating hole, this image positioning apparatus is used for taking the image of this web plate, thereby and adjusts the position of this web plate until the predeterminated position that this at least one mark is positioned at this image aligns respectively this at least one locating hole of at least one print pattern and this.
So arrange, in can be controlled at ± 0.1mm of the precision of this screen press, compared to existing screen printing, precision improves.

The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
Refer to Fig. 1-4, screen press 10 bag one bearing substrate 100, a web plate 200 and image positioning apparatus 300 of better embodiment of the present invention.This bearing substrate 100 comprises a loading end 110, and this loading end 110 offers at least one locating hole 120.Each locating hole 120 is for carrying, locate a material 20 to be printed.Gap between each locating hole 120 and this material 20 to be printed is less than 0.1mm.This web plate 200 offers at least one print pattern 210, and is formed with at least three marks 220.Each print pattern 210 is corresponding with a locating hole 120.This image positioning apparatus 300 is for taking the image of this web plate 200, thereby and adjusts the position of this web plate 200 until the predeterminated position that this at least three marks 220 are positioned at this image aligns respectively this at least one locating hole 120 of at least one print pattern 210 and this.
So arrange, in can be controlled at ± 0.1mm of the precision of this screen press 10, compared to existing screen printing, precision improves.
In present embodiment, the sapphire that this material 20 to be printed is disc-shaped.This screen press 10 is in these material 20 printing functionality shaded areas to be printed.
The number of this at least one locating hole 120 is six, and be arranged in array (2 * 3).The degree of depth of each locating hole 120 is slightly less than the height of this material 20 to be printed, so that this material 20 to be printed is positioned slightly to expose this loading end 110 after each locating hole 120.So, this material 20 to be printed can be fitted with this web plate 200 more closely, improves printing effect.In present embodiment, the degree of depth of each locating hole 120 is less than the height 0.0508mm of this material 20 to be printed.
This bearing substrate 100 also offers at least one through hole 130.Each through hole 130 is corresponding with a locating hole 120, the diameter of each through hole 130 is less than corresponding locating hole 120, and align, be communicated with corresponding locating hole 120, for being connected to vacuum source to utilize negative pressure of vacuum that this material 20 to be printed is adsorbed in corresponding locating hole 120.
In present embodiment, the gap between each locating hole 120 and this material 20 to be printed is less than 0.0508mm.
This web plate 200 is rectangular.In present embodiment, each print pattern 210 is circular hole.The number of these at least three marks 220 is five, lays respectively at four corners and the center of this web plate 200.
This image positioning apparatus 300 comprises an imaging device 310 and an actuator 320.This imaging device 310 is fixedly installed with respect to this bearing substrate 100, and for taking the image of this web plate 200.This actuator 320 is connected with this imaging device 310 and this web plate 200, for drive this web plate 200 to adjust position according to the position relationship between this at least one mark 220 and this predeterminated position.
In practical operation, the position of can be first for example, adjusting this web plate 200 by additive method (range estimation is auxiliary or other optical detections auxiliary) is alignd this at least one locating hole 120 of at least one print pattern 210 and this.In the image that now this imaging device 310 is taken, the position of the image of this at least one each and every one mark 220 is this precalculated position.
In a word; those skilled in the art will be appreciated that; above embodiment is only for the present invention is described; and be not used as limitation of the invention; as long as within connotation scope of the present invention, within the appropriate change that above embodiment is done and variation all drop on the scope of protection of present invention.
