Automation alternative production method of cold cathode fluorescent lamp

Abstract

The invention discloses an automation alternative production method of a cold cathode fluorescent lamp. A rotation chuck (1) is provided with a central shaft (4) and connected with a motor (2) through a driving belt (3), 2-8 sealing resin fixtures (7) are evenly distributed on the rotation chuck (1) and matched with same types or different types of lamp tubes (6), and the sealing resin fixtures (7) can be replaced through screw switches (8). When a production line is started, the motor (2) is started to drive the rotation chuck (1) to rotate so that the sealing resin fixtures (7) in the same types are matched with an assembly line, and accordingly, the automation alternative production method is finished. Compared with automation alternative production methods in prior art, the automation alternative production method of the cold cathode fluorescent lamp is capable of achieving production automation, and problems of high product damage rates and various product qualities which are caused by manual operation are avoided.

Description

technical field [0001] The invention relates to an automatic alternate production method of cold cathode fluorescent lamps, in particular to a method for realizing automatic alternate production of cold cathode fluorescent lamps of the same model or different models by means of combined rotary chucks. Background technique [0002] LCD (liquid crystal display) is one of the main varieties of FPD (flat panel display) in the world. The LCD panel is composed of two layers of glass substrates sandwiching liquid crystals to form a parallel plate capacitor. The TFT embedded in the lower glass substrate controls the capacitor. And the built-in storage capacitor is charged to maintain the voltage required for each image until the next frame is updated. The color of the liquid crystal is transparent, and the LCD must be lined with a white backlight to express the colorful colors, and to make the white backlight reflective, it is necessary to add white lights around it. The LCD itself...

Problems solved by technology

The existing product alternate manufacturing process is mainly through adjusting the sealing resin fixture on a single assembly line to match the inner diameter of the tube of the cold cathode fluorescent lamp to realize the alternate manufacturing of products, but this method is time-consuming and laborious. In order to achieve a good match between the sealing resin fixture and the lamp tube, the product damage rate is increased and the product quality is reduced. Moreover, with the diversification of cold cathode fluorescent lamp models year by year, this production method can no longer meet the needs of mass production.
