Description

Joint cleaning device

This invention relates to a cleaning device, and more particularly to a cleaning device for chemical tank fittings.

Various chemicals are used in the manufacturing processes of electronics, such as semiconductors, wafer foundries, LCD flat panel displays, and solar cells. To prevent chemicals from being exposed to the air and deteriorating or becoming contaminated, chemical tanks are often directly connected to connectors during the manufacturing process, and the chemicals inside the tanks are extracted for operation.

When the chemicals in a chemical tank are used up, the operator separates the connector from the chemicals before replacing it with a new chemical tank. According to standard operating procedures, once the connector is separated from the chemical tank, it must be cleaned to prevent contamination and potential contamination of the chemicals in the next chemical tank. However, repeatedly disconnecting and cleaning the connector from the pipeline causes delays and is time-consuming and labor-intensive.

The present invention provides a joint cleaning device that can support a joint and simultaneously clean the joint with a liquid and dry it with a gas.

The connector cleaning device proposed in this invention comprises: a body having a cleaning space therein; a baffle disposed within the body and positioned above the cleaning space; the baffle having: a through hole communicating with the cleaning space and for supporting the connector; a liquid conduit surrounding the body and allowing liquid to flow through; the liquid conduit having: a liquid inlet through which the liquid flows into the liquid conduit; a plurality of liquid outlets penetrating the wall of the body and communicating with the cleaning space; a gas conduit surrounding the body and allowing gas to flow through; the gas conduit having: an air inlet through which the gas flows into the gas conduit; Multiple air outlets are formed penetrating the wall of the body and connecting to the cleaning space; A row of liquid holes is formed at the bottom of the body.

The advantage of this invention is that the joint cleaning device can support the joint through the through-hole of the baffle, simultaneously clean the joint through a liquid pipeline, and dry the joint through a gas pipeline. For example, when a user replaces a chemical tank, the joint connected to the old chemical tank can be temporarily placed in the joint cleaning device, and simultaneously cleaned and dried by the device. Then, the cleaned joint can be installed into the new chemical tank, completing the standard operating procedure for replacing the chemical tank. In this way, the joint cleaning device can reduce the manpower and time spent on disassembling and cleaning joints.

As described above, the joint cleaning device includes an ultrasonic transmitter disposed in the cleaning space.

The joint cleaning device described above includes: a detection conduit disposed beside the main body; the detection conduit is connected to the main body and communicates with the cleaning space; a control device disposed in the detection conduit; the control device is capable of detecting the liquid level in the detection conduit and controlling the flow of the liquid into the liquid conduit; when the liquid level reaches a predetermined position, the control device stops the flow of the liquid into the liquid conduit.

As described above, in the joint cleaning device, the detection conduit connects to the cleaning space at the bottom of the body.

In the aforementioned joint cleaning device, the upper diameter of the through hole of the baffle is larger than the lower diameter of the through hole.

As described above, when the joint cleaning device is used to support the joint, the liquid outlets and the air outlets face the joint.

As described above, in the joint cleaning device, the gas pipe is located above the liquid pipe.

Please refer to Figures 1 to 6. This invention provides a joint cleaning device that can support a joint A, clean the joint A with a liquid, and then dry the joint A with a gas. The joint cleaning device comprises a body 10, a baffle 20, a liquid conduit 30, a gas conduit 40, a drain hole 50, an ultrasonic transmitter 60, a detection conduit 70, and a control device 80.

A cleaning space 11 is formed inside the body 10. A baffle 20 is disposed in the body 10 and located above the cleaning space 11. The baffle 20 has a through hole 21. The through hole 21 is formed through the center of the baffle 20 and connects to the cleaning space 11. The joint cleaning device carries the joint A through the through hole 21 of the baffle 20. The upper diameter of the through hole 21 is larger than the lower diameter of the through hole 21, and the upper diameter of the through hole 21 is larger than the diameter of the joint A, while the lower diameter of the through hole 21 is smaller than the diameter of the joint A. In other words, the through hole 21 is tapered, and the wall of the through hole 21 is inclined. When the baffle 20 supports the connector A, the connector A will pass through the through hole 21, and the part of the connector A that needs to be cleaned is located in the cleaning space 11.

A liquid conduit 30 is disposed around the body 10 and allows liquid to flow through it. The liquid conduit 30 has an inlet 31 and a plurality of outlets 32. The outlets 32 penetrate the wall of the body 10 and connect to a cleaning space 11. Liquid flows into the liquid conduit 30 from the inlet 31 and then into the cleaning space 11 from the outlets 32. A gas conduit 40 is disposed around the body 10 and allows gas to flow through it. The gas conduit 40 has an inlet 41 and a plurality of outlets 42. The outlets 42 penetrate the wall of the body 10 and connect to the cleaning space 11. Gas flows into the gas conduit 40 from the inlet 41 and then into the cleaning space 11 from the outlets 42.

When connector A is placed in the connector cleaning device, the liquid outlet 32 faces the part of connector A that needs to be cleaned, and liquid can be sprayed from the liquid outlet 32 onto connector A, thereby cleaning connector A. Similarly, when connector A is placed in the connector cleaning device, the air outlet 42 faces the part of connector A that needs to be dried, and gas can be sprayed from the air outlet 42 onto connector A, thereby drying connector A. In this embodiment, the gas pipe 40 is located above the liquid pipe 30, and the air outlet 42 horizontally penetrates the wall of the body 10, while the liquid outlet 32 obliquely penetrates the wall of the body 10, but this is not a limitation.

A drain hole 50 is formed at the bottom of the body 10 and can connect to or block the cleaning space 11 and the outside of the body 10. When the drain hole 50 connects to the cleaning space 11 and the outside of the body 10, the drain hole 50 can drain the liquid located in the cleaning space 11. When the drain hole 50 blocks the cleaning space 11 and the outside of the body 10, the liquid can accumulate in the cleaning space 11, and the part of connector A that needs to be cleaned can be immersed in the liquid. An ultrasonic transmitter 60 is disposed in the cleaning space 11. When the part of connector A that needs to be cleaned is immersed in the liquid, the ultrasonic transmitter 60 can be activated and the connector A is cleaned with ultrasound.

A detection pipe 70 is disposed beside the main body 10 and is connected to the main body 10 and the cleaning space 11. In this embodiment, the detection pipe 70 is connected to the cleaning space 11 at the bottom of the main body 10, but this is not a limitation. A control device 80 is disposed in the detection pipe 70 and can detect the liquid level in the detection pipe 70. According to the principle of the connecting pipe, the liquid level in the cleaning space 11 and the liquid level in the detection pipe 70 are on the same plane. Thereby, the control device 80 can determine the amount of liquid in the cleaning space 11 by detecting the liquid level in the detection pipe 70, and then control the liquid to flow into the liquid pipe 30. Specifically, when the liquid level reaches a predetermined position, the control device 80 can stop the liquid from flowing into the liquid pipe 30. In this embodiment, when the part of joint A that needs to be cleaned is immersed in the liquid, it means that the liquid level has reached the predetermined position, but this is not the only limitation.

First, the connector A to be cleaned is placed in the through hole 21 of the baffle 20, with the part of connector A to be cleaned passing through the through hole 21 and positioned in the cleaning space 11. Then, liquid flows into the liquid pipe 30 from the inlet 31 and is sprayed onto connector A from the outlet 32, thus cleaning connector A. As the liquid cleans connector A, once the injected liquid accumulates to a predetermined position in the cleaning space 11, the control device 80 stops the liquid from flowing into the liquid pipe 30. Subsequently, the ultrasonic transmitter 60 is activated, and connector A is cleaned with ultrasound. Then, the drain hole 50 connects the cleaning space 11 to the outside of the main body 10 to drain the liquid located in the cleaning space 11. Finally, gas is sprayed onto connector A from the outlet 42, thereby drying connector A and completing the cleaning of connector A.

The advantage of this invention is that the joint cleaning device can support joint A through the through hole 21 of the baffle 20, clean joint A through the liquid pipe 30, and dry joint A through the gas pipe 40. For example, when a user replaces a chemical tank, joint A connected to the original chemical tank can be temporarily placed in the joint cleaning device, and joint A can be cleaned and dried simultaneously through the joint cleaning device. Then, the cleaned joint A can be installed into the new chemical tank, completing the standard operating procedure for replacing the chemical tank. In this way, the joint cleaning device can reduce the manpower and time spent on disassembling and cleaning joint A.
