Problems solved by technology

[0003] Manually pointing the carbon paste on the LCD electrodes and then installing the feet can solve the above-mentioned problem of contact resistance, but it is easy to cause a micro-short circuit between the electrodes; in addition, the efficiency of this method of spotting carbon is very low. With the gradual increase of labor costs, the increase Efficiency and automated production have become unavoidable propositions in the manufacturing industry

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] Present embodiment provides a kind of PIN foot point carbon slurry method, as figure 1 with figure 2 As shown, the PIN pin point carbon paste method comprises the following steps: first, step A: the first disc 107 and the second disc 101 that are wound with a strip-shaped PIN pin are placed on the transmission device, and the strip-shaped PIN roll is stretched 106 one end and fix it in the second disc 101, and make the bayonet of each PIN foot in the strip-shaped PIN roll 106 face down.

[0018] Wherein, when in use, the formed strip-shaped PIN roll can be used directly, and the strip-shaped PIN roll is formed by winding and fixing a number of strip-shaped PIN pins fixed with glue in the first disc, and the formed strip-shaped PIN roll can be directly use.

[0019] Then, perform step B: place the carbon slurry box 105 that carbon slurry is housed between t...

Abstract

The invention discloses a method for dispersing carbon paste on pins PIN and a carbon paste dispersing system. The method includes the following steps of firstly, placing a sheet PIN roll on a transmission device, stretching one end of the sheet PIN roll and fixing the end into a second disc, and making bayonets of all the pins PIN in the sheet PIN roll face downwards; secondly, placing a carbon paste box containing the carbon paste between a first disc and the second disc; thirdly, starting the transmission device so that all the pins PIN can pass through the carbon paste box, and winding all the pins PIN in the second disc in rolls after coating the bayonets of all the pins PIN with the carbon paste in the carbon paste box. On the premise of not influencing contact performance, the carbon paste dispersing efficiency is improved, a solution is provided for production automation, the full contact between the pins PIN and an LCD electrode is ensured, and contact resistance is reduced.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a method and a carbon paste pointing system applied to a PIN foot in a liquid crystal display device. Background technique [0002] With the development of science and technology, liquid crystal display is more and more widely used in people's life. Usually, LCDs with PIN pins use metal pins to connect to the LCD to achieve the effect of driving the display. Since the PIN pin is a metal pin, the metal pin and the LCD electrode are in rigid contact. The process adopted in the industry is to coat a layer of conductive carbon paste between the metal pin and the LCD electrode, so that the gap between the PIN pin and the LCD electrode Full contact, reduce contact resistance. [0003] Manually pointing the carbon paste on the LCD electrodes and then installing the feet can solve the above-mentioned problem of contact resistance, but it is easy to cause a micro-short circuit between ...
