A color filter, also known as a "filter lens," is a dyed transparent sheet that absorbs, reflects, and transmits colored light. It is an accessory of reproduction apparatuses, used to select the photosensitive effect during reproduction.

Color filters are absorptive, with different pigments absorbing different spectra. The manufacturing process of such filters is relatively complex, requiring at least three photolithography steps. After this processing step, it is essential to ensure that all contaminants on the surface of the color filter are removed.

For the removal of contaminants, the ultrasonic cleaner in the cleaning equipment can be considered first. Its cleaning principle involves the workpiece being subjected to the impact of "cavitation" generated by high-frequency ultrasound and the continuous up-and-down motion of the system itself during the cleaning process, which increases liquid friction. This allows contaminants on the workpiece surface to quickly detach, achieving high cleanliness.

Analyze the contaminants produced by the product and equip the corresponding ultrasonic cleaning equipment:

The VGT-1209FHA by VGT is an automatic intelligent ultrasonic cleaner for glass. The equipment has 12 functional tanks, equipped with a shaking system, circulation filtration system, automatic constant temperature system, ultrasonic cleaning system, timing system, spray system, slow pull dehydration system, hot air drying system, etc. The equipment uses environmentally friendly water-based solvents for washing and pure water for rinsing, making it an environmentally friendly cleaning system.

Equipment Parameters:

1. Inner basket (fixture) dimensions: approximately L410-W650-H250mm, loading 18 pieces at a time.

2. Cleaning basket load capacity: rated load Min 15Kg, Max 20Kg.

3. Transmission: Automatic intelligent type, with a rod manipulator for transmission.

4. Cleaning cycle: 4–6 minutes per basket (manipulator operation and transmission).

5. Output: For a cycle time of 6 minutes, output depends on the actual usage time of the equipment and manual control time.

Tank Structure:

1. Each tank has four overflow ports, with an overflow tank width of 35 mm. Each tank is an independent circulation tank, where the cleaning agent is pumped from the storage tank by a circulation pump, filtered, and then returned to the cleaning tank, i.e., a mother-daughter tank circulation system.

2. Equipped with an independent circulation filtration system.

3. Each tank has a drain valve at the bottom, connected in series to the main drain pipe.

4. Temperature sensors are installed inside the tanks, with a temperature control range: RT–100°C.

5. External shaking mechanism.

6. Equipped with a heating system.

7. Independent inlet and drainage for each tank.

8. Ultrasonic system uses flange connections.

Ultrasonic Generator:

1. Equipped with a fourth-generation ultrasonic generator, fundamentally ensuring effective ultrasonic conversion rate, ultrasonic performance, and stability of the ultrasonic generator quality.

2. The ultrasonic generator includes a microcontroller with a unique timing system, allowing flexible adjustment of cleaning time according to production needs and enabling one-to-one settings for consistent cleaning.

3. Photoelectric signal display for ultrasonic intensity.

Storage Tank:

1. Divided into two chambers by a partition. The cleaned solution after oil separation is pumped back into the cleaning tank by the circulation pump, achieving self-circulation and improving solution utilization. Separated oil is discharged into the main drain pipe.

2. Equipped with a city water inlet, which can be connected to each washing tank and the storage tank.

Pure Water Pre-Heating Tank Structure:

1. Made of SUS304 with a thickness of 2mm,配有缸蓋, externally insulated with 10.0mm thick保溫棉. Positioned higher than tank 9, it allows a controlled flow into tanks 9 and 8 via a manual valve.

2. Capacity: approximately 60L.

3. Equipped with a low-level stainless steel liquid level controller. When the liquid level is low, the circulation pump automatically shuts off with audible and visual alarms.

4. Manual liquid inlet, adjustable manually,配有玻璃轉(zhuǎn)子流量計, with adjustable flow rate.

Slow Pull Dehydration Tank:

For high-precision surface cleaning, in addition to合理的清洗工藝和配置, excellent dehydration效果 is crucial. Any residue or water spots on the workpiece surface will ultimately lead to coating failure. High-purity water high-temperature slow pull dehydration is an essential step for high-precision cleaning of glass products. It effectively forms a uniform hot pure water film, rapidly evaporates surface moisture, achieves high surface cleanliness, and lays a favorable foundation for subsequent drying.

Hot Air Drying Tank:

1. Inner chamber made of imported SUS304, 2mm thick stainless steel plate,外包不銹鋼沙膠板, with rock wool insulation in between.

2. Each drying tank is equipped with a set of cylinders. The cylinders move along with the glass, forming a sealed cover.

FFU Air Pressure System:

An FFU laminar flow air supply unit is installed on the top of the frame directly above the drying tank. It blows air downward to create negative pressure, preventing contaminants from adhering to the workpiece after heating.
