Adding an acid solution into the pure water tank to adjust the pH value to 5.8-6.5, neutralizing water taken out after passing through the cold water tank, neutralizing alkaline substances in the water, avoiding remaining on the surface of the prism, and leaving water stain marks after the prism is dried.
In step 6, when the quality inspection finds that the prism still has residual colloid, the prism is classified according to the residual colloid amount, the prism performs the glue removing operation again when the residual colloid amount exceeds the set standard, and the manual glue removing treatment is performed when the residual colloid amount is less than the set standard.
Wherein, the manual degumming treatment step comprises the following steps:
step 1: irradiating the residual position of the colloid by using an infrared lamp for heating, wherein the heating temperature is 180-220 ℃;
step 2: continuously irradiating to melt and decompose the colloid, and cleaning the molten colloid by using a colloid removing scraper;
and step 3: after cleaning, the prism is washed by running water, and manual glue removing operation is completed.
When 60% of the softening melting point temperature value of the prism conflicts with 220 ℃, the residual glue is processed by using the temperature while ensuring the stability of the prism structure by taking 60% of the softening melting point temperature of the prism as a reference.
In the step 2, the scraper cleans the molten colloid and sprays atomized neutralizer for neutralization treatment so as to improve cleaning effect and efficiency.

1. according to the invention, the UV glue is subjected to hot-cold treatment by using hot water and cold water, and the effect of expansion with heat and contraction with cold is fully utilized to enable the UV glue adhered to the surface of the prism to be automatically separated from the surface of the prism, so that the UV glue is conveniently subjected to glue removing treatment, the glue removing efficiency is high, the effect is good, and the surface of the prism is not easily damaged.
2. According to the invention, when part of stubborn residual glue remains on the surface of the prism after glue removing treatment, the UV glue is continuously heated by heat at the maximum bearing temperature through infrared heating, so that the molecular chain of the glue is broken, the viscosity of the glue and the surface of the prism is reduced, and thus the cleaning is effectively and quickly carried out.
3. According to the invention, the UV adhesive is firstly removed and cleaned through expansion with heat and contraction with cold, then the UV adhesive residue is decomposed by high-temperature heating, and the UV adhesive on the prism is cleaned in a combined mode, so that the cleaning efficiency and effect are greatly improved, and the production benefits of enterprises are improved.
