Equipment and process method for manufacturing EL luminous signboards by water-flowing type array jet printing

Abstract

The invention discloses equipment and a process method for manufacturing EL luminous signboards by water-flowing type array jet printing. The equipment comprises a belt conveying platform mechanism, a first jet printing nozzle array, a second jet printing nozzle array, a third jet printing nozzle array, a fourth jet printing nozzle array, a fifth jet printing nozzle array and a sixth jet printing nozzle array, UVLED (ultraviolet light-emitting diode) devices are arranged in the rear of nozzles of the first-six jet printing nozzle arrays, a first group of positioning cameras, a second group of positioning cameras and a third group of positioning cameras are arranged in front of the second jet printing nozzle array, the fourth jet printing nozzle array and the sixth jet printing nozzle array respectively, and the first-sixth jet printing nozzle arrays are arranged on the belt conveying platform mechanism sequentially and parallelly. The method includes that a PET (polyethylene terephthalate) polyester film substrate sequentially passes the first to six jet printing nozzle arrays to be subjected to jet printing of an ITO (indium tin oxide) substrate layer, a luminous layer, an insulation layer, a back electrode layer, a protection layer and a front luminous pattern layer. The array jet printing equipment achieves a water-flowing type laminating jet printing process of the EL luminous signboards, solves the problem that traditional vapor deposition methods and coating methods need splicing piece by piece, and can be widely applied to manufacturing of the EL luminous signboards.

Description

technical field [0001] The invention relates to a device and a process method for manufacturing EL luminous signs, in particular to an equipment and a process method for manufacturing EL luminous signs by flow array jet printing, and belongs to the technical field. Background technique [0002] EL cold light sheet is a device that converts electrical energy into light energy. Its working principle is that the particles of zinc sulfide (Phospher Partides) are driven by the AC voltage sandwiched between the two poles to generate an AC electric field. The electrons run at high speed in the light-emitting layer and activate Light-emitting atoms are accelerated to obtain enough energy, and the electrons excited by the electric field collide with the luminescent center and fluorescent substances, resulting in the jump-change-recombination of the electron energy poles, which leads to a physical phenomenon that emits high-efficiency luminescence, that is, electricity excitation ligh...

Problems solved by technology

However, at present, there is no standardized production workshop and professional plate-making, printing, UV and drying integrated assembly line operations in China. Most of them are small-format, hand-made glass screen printing stations, which require large-format light sheets, which can only be spliced ​​one by one. , its effect cannot meet the process requirements
