Embodiment Construction

[0016] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0017] Any feature disclosed in this specification, including any appended claims, abstract and drawings, may, unless expressly stated otherwise, be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0018] Such as image 3 Shown: the first step 31 is the measurement of the ground resistance. For the human body anti-static grounding system, one end of the test point is the static ground wire 210, the other end is the ground 27, and the test resistance is not greater than 10Ω; About 1MΩ; for the tray anti-static grounding system, one end of the test point is the electrostatic brush 22, the other end is the ground 27, and the test resistan...

Abstract

The invention discloses an electrostatic prevention method and an electrostatic prevention system for a PDP module assembly line. The system comprises a tray electrostatic prevention grounding system, a PCB electrostatic prevention grounding system and a human body electrostatic prevention grounding system. The electrostatic prevention method comprises the following three steps of: 1, measuring aresistance; 2, allowing a tray to flow into a station and performing module assembly work; and 3, finishing the module assembly and allowing the tray to flow out. According to the theory of discharging electrostatic charges through grounding, the electrostatic charges on a display module are discharged to the earth through a grounding wire, so that the accumulation of the electrostatic charges onthe display module is reduced, the action time of electrostatic voltage and current is shortened, and the damage of static electricity to products is further reduced.

Description

technical field [0001] The invention relates to an antistatic method and system for a PDP module assembly line. Background technique [0002] The production process of the PDP display module is divided into substrate graphics production, display screen production and module production. Among them, module production is divided into five processes: module assembly, module adjustment inspection, module aging, module final inspection and module packaging. Module assembly is the most critical and important link in module production. Module assembly is the process of assembling the components of the PDP display module according to certain process requirements to form the final form of the product module. Since the processes are connected in series, if there is a problem with module assembly, there will definitely be problems in the subsequent process. It can be seen that the quality of module assembly is a necessary but not sufficient condition for the quality of the entire mod...
