Embodiment Construction

[0049] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail together with the accompanying drawings. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

[0050] In the drawings, the thickness of each element and the like is exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on," "connected to," or "overlapping" another element, it can be directly on the other element. on or connected to another element, or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are...

Abstract

The invention provides a screen printing machine, which includes a conveying device, a loading platform, a printing device and an alignment device. The conveying device is used to move the printed matter in a specific direction. The printed article includes an area to be printed for forming a printed pattern. The loading platform is arranged on the conveying device and is used for loading the printed matter. The printing device is located above the conveying device and includes a screen plate and a scraper. The scraper is located above the screen. The aligning device is located above the conveying device and adjacent to the printing device, and includes an image capturing unit and a tape reel. The image capturing unit is used for capturing the alignment marks on the printed matter. The tape reel is used to stick flexible tape on the printed matter according to the registration mark, so as to define the area to be printed. The present invention can prevent the printed matter from spreading out of the printing area so as to achieve the desired precision standard.

Description

technical field [0001] The invention relates to a screen printing machine, and in particular to a screen printing machine for printing peelable glue on an array substrate. Background technique [0002] The surface of the array substrate will be covered with a peelable adhesive by a screen printing machine before shipment, and it is necessary to prevent the peelable adhesive from being screen printed on the wiring area. For example, the array substrate to be subjected to subsequent side wiring process includes circuit boards on its two opposite surfaces, and the peelable glue needs to maintain a specific distance precision from the side wiring pads. However, the peelable adhesive has the problem of spreading out after screen printing, and the general screen printing machine cannot ensure that the peelable adhesive can maintain a specific distance accuracy from the side wiring pads. Contents of the invention [0003] The purpose of the present invention is to provide a scre...
