A kind of cleaning device and cleaning method for bad screen printing film

Abstract

The invention discloses a cleaning production line and method for screen printing defective pieces. A cleaning device sequentially comprises a feeding device (1), a soaking device (2), an obverse-side flushing device (3), a reverse-side flushing device (4), a drying device (5) and a discharging device (6) from front to back. The feeding device (1), the soaking device (2), the obverse-side flushing device (3), the reverse-side flushing device (4), the drying device (5) and the discharging device (6) are connected through a conveying device (7) in a through mode, and operation tracks (8) are arranged on two sides of the devices. Positioning devices (9) are evenly distributed in the length direction of the operation tracks (8). Each positioning device (9) comprises a fixing clamping block (20), a rotation control device used for controlling the fixing clamping block (20) to rotate, and a horizontal movement control device used for controlling the rotation control device to move front and back. The cleaning device and method have the beneficial effects that the screen printing defective pieces are clamped or released through the horizontal movement control device and are overturned through the rotation control device, so that the obverse sides and the reverse sides are cleaned, and automatic cleaning of the screen printing defective pieces is achieved.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a device for cleaning bad screen printing sheets and a cleaning method thereof. Background technique [0002] The back electric field and back electrode of crystalline silicon solar energy are located on the back of the solar cell, forming the back and lower electrodes of the silicon cell. Cooperating with the upper electrode on the surface of the silicon cell, it plays the role of transmitting the electric energy generated by the silicon solar cell to the outside world. The positive electrode and the back electrode are made of silver paste, and the back electrode is made of aluminum paste through printing, drying, and sintering. [0003] In the normal production process of cell screen printing, there are often some defective screen printing products caused by abnormal printing. These defective products mainly include incomplete graphics on the front, incomplete graphics on the back, and...
