Embodiment 1

[0040] An embodiment of the present invention proposes a cleaning device for a quartz glass plate, which mainly includes four parts: pickling station, pure water rinsing station, pure water ultrasonic cleaning station, and slow drying station. The pickling station uses a sealable container made of PVC material that is resistant to hydrofluoric acid corrosion, and contains a hydrofluoric acid solution with a mass fraction of 0.5-3% inside; the pure water rinsing station uses a container made of PVC material that is resistant to hydrofluoric acid corrosion. Equipped with automatic water inlet and overflow switches; the pure water ultrasonic cleaning station includes at least three levels of cleaning, using a stainless steel sink, with multiple ultrasonic generators evenly distributed at the bottom, the vibration frequency of the ultrasonic generator in the first cleaning tank is 45KHz, and the second The vibration frequency of the ultrasonic generator in the first-level cleaning ...

Embodiment 2

[0046] One embodiment of the present invention proposes a cleaning method for a quartz glass pendulum, which includes: placing the quartz glass pendulum in a cleaning basket, followed by pickling, rinsing, ultrasonic cleaning and slow drying.

[0047] The pickling step is as follows: place the quartz glass pendulum in a cleaning basket, put it into 0.5-3% hydrofluoric acid solution, the temperature is 25°C, and the pickling time is 2-5 minutes. The following chemical reactions take place in the acid solution to etch away the glass surface and any stubborn adherents on it. The cleaning basket is made of acid-resistant plastic, and the pendulum plate is only placed in three-point contact, and multiple pendulum plates can be placed at the same time, and the distance between the plates is not less than 5mm.

[0048] The pure water rinsing step is as follows: the residual acid solution on the surface of the quartz glass pendulum taken out from the acid solution is rinsed with deion...

Abstract

The invention discloses a cleaning method for quartz glass swing pieces. The quartz glass swing pieces are positioned in a cleaning basket for acid washing, rinsing, ultrasonic cleaning and slow-pulldrying in sequence. In the cleaning method for the quartz glass swing pieces, surface attached matters can be effectively removed through hydrofluoric acid dilute solution; then, the surface cleannessis further guaranteed through rinsing and three-stage ultrasonic cleaning; and finally, the slow-pull drying is performed in pure water, and the surface tension of the water and the wind shearing ofhot wind are used for guaranteeing no water, so that the subsequent film plating adhesion of the quartz glass swing pieces is improved. More swing pieces are once cleaned, and are automatically cleaned and dried to prevent the damage of flexible beams of the swing pieces caused by manual cleaning.

Description

technical field [0001] The invention relates to the field of quartz glass, in particular to a method for cleaning a quartz glass pendulum. Background technique [0002] At present, the thickness of the flexible beam of the quartz glass pendulum after acid etching is about 20um, and there will be organic or inorganic adherents and acid residues on the glass surface; the residual acid is removed by washing with clean water for many times, and then placed in alcohol or In an organic solution such as chloroform, use a brush to manually scrub to remove surface adherents, and finally use pure water or a volatile organic solvent to rinse and dry. [0003] There are following deficiencies in the above method: (1) the flexible beam of the pendulum plate is easily damaged during the manual cleaning process with a brush; (2) the degree of cleanliness of the pendulum plate is not high after cleaning. Contents of the invention [0004] The main purpose of the present invention is to p...
