Description

Technical Field

[0001] This utility model relates to the field of cleaning machines, and in particular to an automated cleaning device capable of storing acidic liquids. Background Technology

[0002] Many components in the semiconductor industry are made of plastic. During the manufacturing process, numerous metal ions adhere to their surfaces. Uncontrolled metal ions are completely unacceptable in chip manufacturing. These metal ions, whether from airborne dust, wear and tear on production equipment, or other sources, are extremely harmful to semiconductor chip manufacturing. Even the smallest metal impurities can cause short circuits, affect circuit performance, or even render the entire chip unusable during critical steps in chip manufacturing.

[0003] Traditional ultrasonic cleaning technology, while effective at removing most dirt and particulate matter from object surfaces, often falls short in its ability to remove metal ions tightly bound to plastic surfaces. Typical ultrasonic cleaning cannot completely remove surface metal ions. Acidic liquids are usually used to remove these ions. These acidic liquids react chemically with the metal ions, forming soluble metal salts that separate them from the plastic surface and dissolve them in the liquid. Subsequent rinsing steps then completely remove the metal ions. However, the large-scale use and discharge of acidic liquids can have environmental impacts, such as acid mist emissions and water pH imbalances, and can also increase company costs related to chemical procurement, storage, transportation, and wastewater treatment. Utility Model Content

[0026] After cleaning the workpieces, the acidic liquid is collected and returned to the acidic liquid storage tank instead of being directly discharged into the environment.

When the acidic liquid no longer meets the cleaning requirements, it can be reconstituted to restore its performance, further extending the service life of the acidic liquid.

[0033] An ultrasonic cleaning module 6 is installed on the partition plate 2 near the cleaning tank 1.

[0034] The cleaning tank 1 is equipped with a pure water inlet pipe 8 and a pure water outlet pipe 9 on its outer wall, and a solenoid valve 7 is installed on both pipes. By opening and closing the solenoid valve 7, the flow of acidic liquid and pure water is precisely controlled, thus automating the cleaning process.

[0036] The automated cleaning equipment includes a housing, which is divided into a cleaning tank 1 and an acid storage tank 3 by a partition plate 2.

It provides a closed environment, ensuring that acid does not leak during the cleaning process, thus protecting the safety of operators and maintaining a clean environment. The partition plate design not only separates the cleaning and storage functions but also improves the space utilization of the equipment.

[0037] Example 4

[0038] like Figure 1 and Figure 2 As shown, an automated cleaning device capable of storing acidic liquids is disclosed. The automated cleaning device includes a cleaning tank 1, a partition plate 2 disposed below the cleaning tank 1, an acid storage tank 3 disposed below the partition plate 2, and an acid circulation drain pipe 4 disposed on the partition plate 2 connecting the cleaning tank 1 and the acid storage tank 3. An acid circulation inlet pipe 5 is disposed outside the cleaning tank. The inlet end of the acid circulation inlet pipe 5 is connected to the outer wall of the cleaning tank 1, and the outlet end of the acid circulation inlet pipe 5 is connected to the outer wall of the acid storage tank 3.

[0039] After cleaning the workpieces, the acidic liquid is collected and returned to the acidic liquid storage tank instead of being directly discharged into the environment.

When the acidic liquid no longer meets the cleaning requirements, it can be reconstituted to restore its performance, further extending the service life of the acidic liquid.

[0040] An ultrasonic cleaning module 6 is installed on the partition plate 2 near the cleaning tank 1.

[0041] Solenoid valves 7 are installed on the acid circulation drain pipe 4 and the drain pipe 11. Pure water inlet pipe 8 and pure water outlet pipe 9 are installed on the outer wall of the cleaning tank 1, and solenoid valves 7 are also installed on these pipes.

The pre-programmed operation of the solenoid valves 7 makes the cleaning process more stable and reliable.

[0042] A pump 10 is installed on the acid circulation water supply pipe 5. The function of the pump 10 is to pump the acidic liquid from the storage tank to the cleaning tank 1, providing power for the circulation cleaning. The automated pump 10 reduces manual operation and improves cleaning efficiency.

[0043] The cleaning tank 1 has an inclined structure, with the acid circulation drain pipe 4 located at its lowest point. This inclined design allows the liquid in the cleaning tank 1 and storage tank to flow naturally to the lowest point, facilitating centralized discharge and recycling. In the multi-functional cleaning tank 1, this structure helps the acid flow smoothly into the acid circulation drain pipe 4 after cleaning, reducing residue and waste.

[0044] The acid storage tank 3 has a drain pipe 11 installed on its outer wall. The acid storage tank 3 has an inclined structure, with the drain pipe 11 located at its lowest point. This inclined structure ensures that waste liquid or liquid requiring treatment can be completely discharged through the drain pipe 11, preventing liquid stagnation and contamination. Theoretically, the liquid in the acid storage tank can be reused indefinitely. If the liquid no longer meets requirements after a period of use, it can be reconstituted according to the required pH ratio until the pH value meets the requirements. When it is necessary to empty the acid storage tank, the solenoid valve 74 can be opened to collect the acidic liquid for proper waste disposal.

[0045] Initial working principle: Place the workpiece requiring acid pickling to remove metal ions into cleaning tank 1, pour in the preset amount of acidic liquid, and measure whether the pH value meets the requirements. The ultrasonic cleaning module 6 starts and cleans the workpiece containing metal ions for 20 minutes. After cleaning, open the solenoid valve 71 of the acid circulation drain pipe 4, allowing all the acidic liquid to enter the acidic liquid storage tank. Then close the solenoid valve 71 and open the solenoid valve 72 of the pure water inlet pipe 8 to inject pure water to the preset water level. Close the solenoid valve 72 and start the ultrasonic cleaning module 6 to clean for 20 minutes. After cleaning, open the solenoid valve 73 of the pure water drain pipe 9 and then close the solenoid valve 73.

[0046] Acid circulation working principle: Place the workpiece requiring acid pickling to remove metal ions into cleaning tank 1, turn on pump 10, and acidic liquid is pumped from the acidic liquid storage tank to the multi-functional cleaning tank 1. Turn off pump 10 and start ultrasonic cleaning module 6 for 20 minutes. After cleaning, open solenoid valve 71 of acid circulation drain pipe 4, and after all acidic liquid has entered the acidic liquid storage tank, close solenoid valve 71. Open solenoid valve 72 to inject pure water to the preset water level line, close solenoid valve 72, and start ultrasonic cleaning module 6 for 20 minutes. After cleaning, open solenoid valve 73 to release pure water and then close solenoid valve 73.

[0047] The advantages of this invention are as follows: The design of the acid storage tank 3 achieves efficient cleaning and resource recycling, significantly reducing production costs and environmental pollution. Simultaneously, the equipment features automation and intelligence, precisely controlling the cleaning process through preset programs and solenoid valves 7, thus improving production efficiency. The equipment employs an inclined structure for the cleaning tank 1 and acid storage tank 3, along with a low-end circulating water pipe and drain pipe 11, ensuring smooth acid flow and recovery.
