Abstract

The invention discloses a polyimide screen hot-pressing device and a method for using the same, wherein the polyimide screen hot-pressing device includes a hot-pressing chamber, a screen placement platform, a hot-pressing roller and a heating device, and the screen The placing table is set horizontally in the hot-pressing chamber for placing the screen horizontally, and a hot-pressing hole is opened in the center of the screen placing table; two hot-pressing rollers are arranged on the upper side and The lower side, and can move up and down vertically relative to the screen plate placement table, contact and squeeze the upper and lower sides of the screen plate with symmetrical lines, the hot pressing roller can also rotate around its own axis, and the two hot pressing rollers can move relative to each other. The screen plate placing table moves synchronously and horizontally in a direction perpendicular to the axis of the heat press roller itself, and reciprocally rolls and squeezes the screen surface of the screen plate within the vertical projection range of the heat press hole; the heating device is installed inside the heat press roller to heat Heat press roller. The invention can realize hot pressing of the polyimide film on the screen surface under normal pressure, has simple structure, and is simple and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of polyimide screen plates, and in particular relates to a polyimide screen plate hot-pressing device and a using method thereof. Background technique [0002] Screen printing is one of the important processes in the production of crystalline silicon cells. Its basic principle is to pass the conductive paste through the screen and transfer the designed graphics to the silicon wafer under the action of a scraper; the main purpose of screen printing is to Fine circuits are prepared on the surface of silicon wafers to collect photo-generated carriers and lead them out to the battery, which is to form the positive and negative electrodes of crystalline silicon solar cells. [0003] Polyimide screen is a new type of screen that has emerged in recent years. Unlike the traditional use of photosensitive glue to make graphics, polyimide screens do not require coating, exposure and development. One of the most critic...
