Embodiment Construction

[0028] A doctor blade structure for screen printing according to a preferred embodiment of the present invention will be described below with reference to related drawings, wherein the same components will be described with the same symbols.

[0029] Please refer to image 3 As shown, a scraper structure 3 for screen printing according to a preferred embodiment of the present invention includes a body 30 and a scraper 31 . The scraper 31 is disposed on one side of the body 30 , and preferably, the body 30 and the scraper 31 can be integrally formed. There are a plurality of cutting slits 32 on the scraper 31 to partially form a plurality of partitions 31 a on the scraper 31 . In this embodiment, the preferred material of the scraper 31 is a rigid material, which can be metal or alloy, such as steel or stainless steel. In addition, the body 30 has at least one positioning hole 33 for fixing on an automatic machine such as a screen printing device (not shown).

Abstract

The invention relates to a scraper structure used for screen printing, which comprises a body and a scraper. The scraper is arranged on a side of the body, and is provided with a plurality of cutting gaps, thereby forming a plurality of cutting sections. The scraper structure used for screen printing avoids that the screen surface is deformed and scratched when the scraper structure under pressure acts on the screen, keeps the flatness of the screen surface and prolongs service life of the screen.

Description

technical field [0001] The invention relates to a scraper structure, in particular to a scraper structure for screen printing. Background technique [0002] Due to the development of consumer electronics products in the direction of lightness, thinness, shortness and smallness, Surface Mounted Technology (SMT) has become the mainstream technology in the electronic packaging industry. Surface mount technology includes three process stages: solder printing, placing electronic components and reflow soldering (solder reflowing). Among them, the solder printing uses a scraper structure to fill the solder into the pattern holes of the screen. [0003] Please refer to figure 1 As shown, a known scraper structure 1 for screen printing includes a body 10 and a scraper 11 . The scraper 11 is disposed on one side of the body 10 . The body 10 and the scraper 11 are integrally formed, and the scraper 11 has deformation elasticity when pressed down. Please refer to figure 2 As show...
