Single material maintenance and replacement process of whole group of consumed material

Abstract

The invention discloses a single material maintenance and replacement process of the whole group of consumed material. The single material maintenance and replacement process comprises the following steps of S1, detecting the whole group of consumed material, judging an unfavorable phenomenon of the whole group of consumed material, determining a range of an unfavorable single material, sequentially detecting single materials within the range, and determining the unfavorable signal material; S2, cleaning the whole group of consumed material with ultrasonic wave, and drying the whole group of consumed material under 40-45 DEG C; S3, placing the whole group of consumed material on a die, and performing dust removal and electrostatic elimination; and S4, reversely disassembling the whole group of consumed material according to an assembly sequence until the unfavorable single material is disassembled, detecting the unfavorable single material, maintaining or replacing the unfavorable signal material, and cleaning and drying other disassembled single materials. By the single material maintenance and replacement process, the detection accuracy can be guaranteed, the quality of the wholegroup of consumed material which is assembled again can be guaranteed, the material loss can be reduced, the production cost is reduced, a reason of generating an unfavorable phenomenon can be determined, the unfavorable phenomenon is prevented from being generated again, and the process is simple and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of backlight sources, and in particular to a single maintenance and replacement process for a whole set of consumable materials. Background technique [0002] Liquid crystal display technology is one of the most widely used display technologies at present, and will occupy the mainstream technology position in the field of flat panel display for a period of time; liquid crystal molecules themselves do not emit light, and the images or characters it displays are emitted by them to the backlight. As a result of light modulation, the backlight source is an important component that determines the performance of the liquid crystal display, and the brightness of the backlight source directly determines the display brightness of the LCD surface. [0003] The liquid crystal backlight system is mainly composed of light source, light guide plate, various optical films and structural parts. Its development tends to be d...

Problems solved by technology

[0004] It is understood that most of the current liquid crystal backlight system has to replace the entire set of consumables when a defect occurs. Although it saves time, it is a waste of resources, and the cause of the defect is not clear, and the same defect will easily occur again. , therefore, we propose a single maintenance and replacement process for the whole group of consumables to solve the above problems
