Problems solved by technology

[0004] After the crystal is processed into a crystal wafer, it needs to be cleaned to remove the impurities on the surface. The existing cleaning methods have a poor cleaning effect on the crystal. It is manual inspection, the inspection efficiency is low, the eyes are prone to fatigue after long-time manual work, and the false detection rate is high, which greatly increases the production cost of the enterprise

Embodiment 1

[0041] Such as Figure 1-13 Shown, a kind of method that is used for crystal cleaning improves crystal surface processing precision, comprises the following steps:

[0042] a. Pre-cleaning: put the crystal wafer in pure water for ultrasonic or megasonic heating pre-cleaning;

[0043] b. Pickling: place the pre-cleaned crystal in hydrochloric acid solution for pickling;

[0044] c. Deacidification: put the pickled crystal in the crystal cleaning machine for cleaning to remove the acidic solution and dirt on the surface;

[0045] d. Drying: place the deacidified crystal wafers in a dryer for drying;

[0046] e. Inspection: Put the dried crystal chips into the crystal inspection device for inspection, and screen out the crystal chips with surface defects;

[0047] The temperature of the pure water used in step a is 60°C.

[0048] The concentration of hydrochloric acid used in step b is concentration 5%.

[0049] Crystal pickling time in step b is 20s.

[0050] In further de...

Abstract

The invention discloses a method used for cleaning rock crystals and improving rock crystal surface machining precision. The method comprises the following steps that a, pre-cleaning is conducted, rock crystal sheets are placed in pure water to be subjected to ultrasonic or megasonic heating pre-cleaning; b, acid pickling is conducted, and the pre-cleaned rock crystal sheets are placed in a hydrochloric acid solution to be subjected to acid pickling; c, acid removal is conducted, the rock crystal sheets obtained after acid pickling are arranged in a rock crystal cleaning machine to be cleaned,and a surface acid solution and dirt are removed; d, drying is conducted, and the rock crystal sheets obtained after acid removal are arranged in a drying machine to be dried; and e, checking is conducted, the dried rock crystal sheets are placed in a rock crystal checking device to be checked, and rock crystal sheets with surface defects are screened out. The method has the advantages that the cleaning effect is good, the checking efficiency is high, and the checking accuracy rate is high.

Description

technical field [0001] The invention relates to the technical field of crystal cleaning, in particular to a method for improving crystal surface processing precision used for crystal cleaning. Background technique [0002] Crystal (rock crystal) is a rare mineral, a kind of gem, quartz crystal, which belongs to the quartz family in mineralogy. The main chemical composition is silicon dioxide, the chemical formula is SiO2. [0003] When pure, it forms colorless transparent crystals. When it contains trace elements Al, Fe, etc., it is pink, purple, yellow, brown, etc. Different types of color centers are formed by irradiating trace elements to produce different colors, such as purple, yellow, brown, pink and so on. Minerals containing accompanying inclusions are called inclusion crystals, such as hair crystals, green ghosts, red rabbit fur, etc., and the inner inclusions are rutile, tourmaline, actinolite, mica, chlorite, etc. [0004] After the crystal is processed into a...
