Description

Technical Field

[0001] The present invention relates to the field of light-transmitting hole filling of electroforming screens, and in particular to a light-transmitting hole filling device of electroforming screens. Background Art

[0002] Electroformed screens have great advantages over woven mesh screens. The graphic structure can be freely adjusted according to design requirements. Due to the presence of warp and weft lines and mesh knots in woven mesh screens, these structures will block the falling of silver paste. However, electroforming can achieve the goal of having no connecting structure in the opening where the silver paste is dropped. Therefore, it can effectively reduce the unit consumption of silver paste while maintaining efficiency. Pure metal screens are generally prepared by electroforming process. Compared with other technical routes, electroforming process has the advantages of precise and adjustable opening size and high opening quality. Electroformed screens are electroformed and grown on a mold with a conductive core mold as the substrate. However, if there are non-conductive impurities in the conductive area on the surface of the mold core mold, such as dust, stains or residual film from development, this area will be non-conductive and cannot be printed. Light-transmitting holes are formed in the metal on the electroforming process, and the problem of slurry leakage will occur in the printing process. Once a metal screen has light-transmitting holes, it can only be scrapped. Therefore, metal light-transmitting holes are a major defect that restricts the yield rate of screen manufacturing. The size of the light-transmitting holes is basically at the micron level, mainly distributed between several to tens of microns. Due to the small size, conventional solutions for repairing metal through-holes, such as tin filling or dispensing, are not practical here. The volume of a single droplet is too large compared to the area or volume of the hole. In addition, the repair of the light-transmitting holes in the screen must be flat and heat-resistant. If the repaired area is higher than the normal area after repair, it may squeeze the silicon wafer or scratch the scraper. If the temperature is too high during the repair process, the repaired area will be deformed and the strength will be reduced.

[0003] Therefore, it is necessary to propose an electroforming screen light hole filling device to solve the above problems. Summary of the Invention

[0022] It should be noted that the present invention is a device for filling light-transmitting holes in an electroformed screen. When in use, various parts of the electroformed screen are scanned and microscopic images are taken. The coordinate positions of the centers of each microscopic image are recorded during scanning. After scanning, the captured microscopic images are analyzed using an existing AOI defect recognition algorithm to obtain the position coordinates of the light-transmitting points in the developed image. The X and Y coordinates of each light-transmitting point are obtained in combination with the coordinate positions of the centers of each microscopic image.

[0023] Specifically, the electroforming screen is placed on top of the third displacement platform 18, and the bidirectional screw 24 is started to drive the limit assembly 19 to move.

The coordinate position of the center of each microscopic image is recorded during scanning. After scanning, the captured microscopic image is analyzed by the existing AOI defect recognition algorithm to obtain the position coordinates of the light-transmitting point in the developed image. The X and Y coordinates of each light-transmitting point are obtained by combining the coordinate position of the center of each microscopic image.

The magnetic UV curing agent is introduced into the light-transmitting hole mainly by means of magnetic suction. The pneumatic push rod 12 is closed, and the first displacement platform 4 is moved to drive the end face of the polyester fiber strip to move horizontally through the light-transmitting hole to remove the magnetic UV curing agent that may overflow from the surface of the electroformed screen. Then, the collimating lens 17 of the curing laser 16 is directed to the light-transmitting hole, and the UV laser is turned on for 1min-2min to cure the magnetic UV curing agent in the light-transmitting hole. After completing the above actions, the strong magnet 31 is closed, and the magnetic UV curing agent in the light-transmitting hole is cured by moving the first displacement platform 4. A displacement platform 4, a fourth displacement platform 28, a third displacement platform 18, a first Z-axis guide rail 6, and a second Z-axis guide rail 30 are used to move the light source 5 and the camera 29 to the position opposite the light-transmitting hole, confirm that the hole filling is completed, turn on the electric winding roller 15, and wind the polyester fiber strip with a length of 0.5-1mm onto the electric winding roller 15, remove the polyester fiber strip that may be stained with magnetic UV curing agent directly on the pressure roller 13, and then repeat the above actions to perform the above hole filling operation on all the light-transmitting holes in the sequence. When all the light-transmitting holes are filled, the poor light transmittance of the electroformed screen can be eliminated.
