Embodiment Construction

[0023] The present invention is described in further detail below:

[0024] A method for manufacturing a platinum heater for a TFT glass substrate, specifically comprising the following steps:

[0025] 1. First, clean and dry the platinum heater brick;

[0026] 2. Wrap the platinum wire in the slot of the platinum heater brick without damage;

[0027] 3. Weld the wound platinum wire with the external lead wire;

[0028] 4. Fill the platinum heater line slot with high silica hollow ball viscous liquid and smooth it to dry;

[0029] 5. Wrap and seal the welded leads with high silicon oxide cloth.

[0030] Among them, step 1 is specifically: clean the platinum heater brick and the platinum heater brick line groove with a plastic brush, and then use high-pressure air to dry the cleaned platinum heater brick; and then dry the platinum heater brick after drying. The bricks are scrubbed with ethanol to achieve the purpose of removing impurities that exist after the platinum heate...

Abstract

The invention discloses a method for manufacturing a TFT glass substrate platinum heater. By performing cleaning and drying on processed platinum heater bricks, material that causes the platinum poisoned does not exist in slots of the platinum heater bricks, and the case that the platinum wires lose original features is prevented; then the platinum wires are winded in the slots of the platinum heater bricks without damages so that the problem of burning out of the platinum wires is prevented during heating application; then the brick slots are filled with silica-rich hollow balls and then smoothed and dried so that the platinum wires are protected from being damaged so that the quality of the platinum heater is further increased and the service life of the platinum heater is increased.

Description

technical field [0001] The method relates to a method for manufacturing a platinum heater used in the manufacturing process of a liquid crystal glass substrate, in particular to a method for manufacturing a platinum heater for a TFT glass substrate. Background technique [0002] The platinum heater for the liquid crystal glass substrate plays an important role in the production process. Although its heating capacity is not very large, it can create a continuous and stable temperature environment for the glass. In actual production, platinum heaters are required to maintain stable heating for a long time and not to be damaged after long-term use. Due to the limitation of the preparation process of the existing platinum heater, it is easy to cause "platinum poisoning" in the process of processing. "Platinum poisoning" is the corrosion of platinum by carbon atoms, making the platinum black and loose, thus losing the original platinum. characteristic. The chemical reaction bet...
