Fluid control valve, refrigerant device, and processing machine

Abstract

The fluid control valve includes a valve member, a valve blocker, and an anti-leaking member. The valve member has a first cavity, a second cavity, and a third cavity communicating with each other. A first contacting portion and a pushing portion are arranged outside the first cavity. The valve blocker is movable in the first cavity to close or to open the second and the third cavities. The anti-leaking member is formed with a connecting portion and a sealing portion with a mark therein. An end of the sealing portion is defined as a second connecting portion to be removably connect to the first connecting portion. The other end of the sealing portion is defined as a dodging portion. When the anti-leaking member is locked on the valve member, the sealing portion is pushed by the pushing portion and contacts the opening of the first cavity so as to move toward the dodging portion. Thereby, the mark is located at a predetermined position to notice the user that the first cavity has been sealed by the anti-leaking member.

Description

Fluid control valves, refrigerant units and operating machines The present invention provides a fluid control valve that allows for rapid confirmation that the anti-leakage component has tightly and reliably sealed the first chamber of the valve, thereby improving the anti-leakage performance. Currently, as shown in Figures 1 to 3, the testing machine is equipped with a testing device 12 on the machine base 11. The testing device 12 is equipped with a tester 121 for holding and testing electronic components, and a crimping arm 122 that can be displaced in the YZ direction. The crimping arm 122 is equipped with a temperature controller 123 and a pressure reducer 124. The temperature controller 123 is connected to a refrigerant device 13 independently configured outside the machine base 11. The first delivery pipe 131 of the refrigerant device 13 is connected to a fluid control valve, which can be a refrigerant control valve 132, located on the side of the machine base 11. The refrigerant control valve 132 is connected to the temperature controller 123 via a second delivery pipe 133, so that the refrigerant device 13 delivers refrigerant to the temperature controller 123 through the first delivery pipe 131, the refrigerant control valve 132, and the second delivery pipe 133. The temperature controller 123 can control the temperature of the electronic components of the tester 121 through the pressure reducer 124, so that the electronic components can perform testing operations in a low-temperature environment simulating the future application environment. When moving the testing machine, the operator must separate the first delivery pipe 131 of the refrigerant device 13 from the refrigerant control valve 132 and close the refrigerant control valve 132. As shown in Figure 2, the refrigerant control valve 132 has a first chamber 1321, a second chamber 1322 and a third chamber 1323 that are in communication. The third chamber 1323 is connected to the first delivery pipe 131. The second chamber 1322 is also equipped with a connecting pipe 1324 to connect to the second delivery pipe 133. A movable valve plug 1325 with an O-ring 1326 is inserted into the first chamber 1321. The refrigerant control valve 132 is also equipped with a cap 1327 with a thin gasket 1328 inside to close the opening of the first chamber 1321. The operator can first remove the cap 1327 and rotate the valve plug 1325 to move it inward in the first chamber 1321 to close the second chamber 1322 and the third chamber 1323, thereby closing the refrigerant control valve 132. Conversely, as shown in Figure 3, after positioning and testing the machine, the valve plug 1325 can be rotated to move in the opposite direction to open the second chamber 1322 and the third chamber 1323, and the cap 1327 can be screwed onto the outside of the first chamber 1321. A thin gasket 1328 can be used to seal the opening of the first chamber 1321 to prevent refrigerant leakage. However, as shown in Figure 3, under repeated opening and closing operations, the O-ring 1326 of the refrigerant control valve 132 is prone to wear and deformation due to reciprocating friction within the first chamber 1321. The thin gasket 1328 will also become concave and deformed due to repeated installation and removal of the cover 1327. Under these deformation factors, if the force of the operator manually locking the cover 1327 is insufficient, the concave and deformed thin gasket 1328 of the cover 1327 may not be able to fit tightly against the opening of the first chamber 1321, causing refrigerant to leak between the first chamber 1321 and the cover 1327. This not only wastes refrigerant energy costs but also requires downtime to deal with the leaked refrigerant, affecting production efficiency. For countries with high environmental protection requirements, the leaked refrigerant will cause environmental pollution in the site, which is even more inconsistent with the high environmental protection requirements. The first objective of this invention is to provide a fluid control valve, comprising a valve, a valve plug, and a leak-proof component. The valve has a first chamber and a second chamber communicating along a first axial direction, and a third chamber communicating with the first chamber along a second axial direction. A first engaging portion and a pushing portion are provided outside the first chamber. The valve plug is displaceable within the first chamber of the valve to open and close the second and third chambers. The leak-proof component has a connecting portion and a stop-seal portion with at least one mark formed on its inner wall surface. The stop-seal portion is relative to the pushing portion of the valve and defines a second engaging portion on one side, allowing it to displace along the first engaging portion of the valve. A clearance portion is defined on the other side, allowing the stop-seal portion to be displaced along the first axial direction under force, enabling the mark to be positioned at a preset identification position. This allows operators to quickly identify whether the leak-proof component has reliably sealed the first chamber of the valve by checking with tools or visually inspecting whether the mark on the leak-proof component is at the preset identification position, achieving the practical benefit of reliable leak prevention. The second objective of this invention is to provide a fluid control valve in which one side of the anti-leakage component is provided with a bearing surface. When the mark on the other side is located at a preset identification position, it can ensure that the bearing surface has tightly sealed the first chamber to prevent fluid leakage. This eliminates the need for downtime to clean up the leaked fluid, thereby achieving the practical benefits of saving fluid energy costs and improving production efficiency. The third objective of this invention is to provide a fluid control valve in which, when the mark on the anti-leakage component is located at a preset identification position, it can ensure that the bearing surface has tightly sealed the first chamber to prevent leakage, thereby effectively preventing the fluid from the fluid control valve from polluting the factory area and improving the environmental quality of the factory area. The fourth objective of this invention is to provide a refrigerant device, comprising a refrigerant mechanism and the fluid control valve of this invention; the refrigerant mechanism is provided with at least one refrigerant reservoir, at least one first conveyor and at least one second conveyor, the refrigerant reservoir being able to supply refrigerant, and the first conveyor being connected to the refrigerant reservoir to convey refrigerant; the fluid control valve of this invention comprises a valve, a valve plug and a leak-proof component, the third chamber of the valve being able to communicate with the first conveyor of the refrigerant mechanism, and the second chamber being able to communicate with the second conveyor, and the fluid control valve being able to reliably control the supply or stoppage of refrigerant. The fifth objective of this invention is to provide a working machine, comprising a machine base, a feeding device, a receiving device, a working device, a refrigerant device of this invention, a transfer device, and a central control device. The feeding device is disposed on the machine base and is provided with at least one feeder for accommodating at least one electronic component to be tested; the receiving device is disposed on the machine base and is provided with at least one receiver for accommodating at least one tested electronic component; the working device is disposed on the machine base and is provided with at least one working device and at least one temperature controller, the working device being used to perform preset operations on the electronic component, and the temperature controller being used to control the temperature of the electronic component; the refrigerant device includes...

The refrigerant mechanism is provided with at least one refrigerant reservoir, at least one first conveyor and at least one second conveyor. The refrigerant reservoir is capable of supplying refrigerant. The first conveyor is connected to the refrigerant reservoir to convey refrigerant. The second conveyor is connected to a thermostat to convey refrigerant.

A transfer device is disposed on the machine base and is provided with at least one transfer device for transferring electronic components. A central control device is used to control and integrate the operation of each device to perform automated operation. To enable your review committee to gain a further understanding of the present invention, a preferred embodiment is described in detail below with reference to the accompanying drawings: Please refer to Figure 4. The fluid control valve 20 of the present invention includes a valve 21, a valve plug 22, and a leak-proof component 23. The valve 21 has a first chamber and a second chamber communicating with each other along the first axis A, and a third chamber communicating with the first chamber along the second axis B. The valve 21 also has a push part and a first engagement part outside the first chamber. In this embodiment, the valve 21 is provided with a first valve section 211 and a second valve section 212 along the first axial direction A, and a third valve section 213 of appropriate length along the second axial direction B. The first valve section 211 has a first chamber 214 with a larger diameter recessed at its end along the first axial direction A, and the interior of the first chamber 214 is provided with an internal thread 2141. The second valve section 212 has a second chamber 215 with a smaller diameter recessed at its end along the first axial direction A and communicating with the first chamber 214. The second chamber 215 and the first chamber 214 are designed in a stepped manner. The end of the third valve section 213 has a third chamber 216 that communicates with the first chamber 214 recessed along the second axial direction B. The valve 21 defines a push portion 217 at the end of the first valve section 211. That is, the push portion 217 is defined on the outside of the first chamber 214. Furthermore, the push portion 217 can have an appropriate taper. The valve 21 has a first engagement portion 218 between the push portion 217 and the third valve section 213. In this embodiment, the first engagement portion 218 is an external thread. The valve plug 22 can be displaced in the first chamber 214 of the valve 21, thereby opening and closing the second chamber 215 and the third chamber 216. In this embodiment, one end of the valve plug 22 is provided with a stop portion 221, and the other end is provided with a drive portion 222. The drive portion 222 is a polygonal hole for a drive tool (such as a screwdriver or hex wrench, not shown in the figure) to engage and drive the valve plug 22 to move. The outer ring surface of the valve plug 22 is provided with an external thread 223, which can engage with the internal thread 2141 of the first chamber 214 and move along the first axial direction A, or can disengage from the internal thread 2141 of the first chamber 214 and disengage from the valve 21. At least one O-ring 224 is fitted on the outer ring surface of the valve plug 22 at an appropriate position near the drive portion 222 to assist in preventing leakage. The anti-leakage component 23 has a connecting part and a stop-seal part with at least one mark formed on its inner wall surface, the stop-seal part being opposite to the push part 217 of the valve 21. In this embodiment, the leak-proof component 23 has a hollow space inside that extends along the first axial direction A and passes through the first surface 231 and the second surface 232. A connecting portion 234 is formed radially extending from the inner wall surface 233 of the hollow space. Furthermore, the connecting portion 234 can be a bendable and deformable annular plate surface or a rib. In this embodiment, the leak-proof component 23 has a bendable and deformable annular plate surface connecting portion 234 extending from the inner wall surface 233 toward the first axial direction A. The connecting portion 234 of the anti-leakage component 23 is connected to the sealing portion 235. Furthermore, the thickness of the sealing portion 235 is equal to or greater than the thickness of the connecting portion 234. In this embodiment, the sealing portion 235 is formed by radially extending the connecting portion 234, and the thickness of the sealing portion 235 is greater than the thickness of the connecting portion 234, and is relative to the first chamber 214 and the push portion 217 of the valve 21. The sealing part 235 defines a bearing surface 2351 in a region of the push part 217 of the valve 21. The area of ​​the bearing surface 2351 is larger than the area of ​​the opening of the first chamber 214, so as to ensure the sealing of the first chamber 214. The sealing portion 235 has a mark in at least one area of ​​the relative clearance portion. Furthermore, the mark can be a surface or a symbol; the symbol can be a polygonal pattern or a color ring, etc., all of which can be identifiable by personnel. For example, the sealing portion 235 may be marked by one surface of the relative clearance portion. For example, the sealing portion 235 may have a mark on the outer ring surface of an area of ​​the relative clearance portion; the aforementioned methods are not limited to this embodiment. In this embodiment, the sealing portion 235 is marked 2352 by one surface of the relative clearance portion, allowing personnel to identify whether the mark 2352 is located at a preset identification position C using inspection tools or visual inspection. The leak-proof member 23 is defined by the second surface 232 as the preset identification position C. Depending on the operational requirements, the preset identification position C can be a position that is flush with or extends beyond the second surface 232 of the anti-leakage component 23. The anti-leakage member 23 has a second joint portion 236 defined on one side of the sealing portion 235. The second joint portion 236 can be displaced along the first joint portion 218 of the valve 21. In this embodiment, the sealing portion 235 of the anti-leakage member 23 is divided into a second joint portion 236 and a relief portion 237 in the hollow space. The second joint portion 236 is defined on one side of the sealing portion 235. That is, the anti-leakage member 23 has the second joint portion 236 recessed from the first surface 231 toward the sealing portion 235. The inner ring surface of the second joint portion 236 is provided with an internal thread, which can be screwed and assembled into the first joint portion 218 of the valve 21 and displaced along the first axial direction A, or disengaged from the first joint portion 218 and removed. The leak-proof member 23 defines a clearance portion 237 on the other side of the sealing portion 235. The clearance portion 237 allows the sealing portion 235 to be displaced along the first axial direction A under force, enabling the mark 2352 to be located at a preset identification position C. In this embodiment, the second surface 232 of the leak-proof member 23 is recessed towards the sealing portion 235 with the clearance portion 237. The depth of the clearance portion 237 is smaller than the depth of the second joint portion 236, which shortens the actuation time of the mark 2352 of the sealing portion 235 to the preset identification position. The mark 2352 of the sealing portion 235 is relative to the clearance portion 237. Depending on the operational requirements, the second chamber 215 of the valve 21 can be equipped with at least one transfer pipe 24, which can transport fluid from the valve 21. Referring to Figure 5, the fluid control valve 20 can control the delivery of fluid, which can be refrigerant or gas, etc. In this embodiment, the fluid control valve 20 is applied to a refrigerant device (not shown in the figure) as a refrigerant control valve, and the fluid is refrigerant. The third valve section 213 of the valve 21 of the fluid control valve 20 can be fitted with the first delivery device 31 of the refrigerant device. The first delivery device 31 can deliver refrigerant from a refrigerant device (not shown in the figure) to the third chamber 216 of the valve 21. The second valve section 212 of the valve 21 can be fitted to the side of the machine base 40 and connected to the second delivery device 32 of the refrigerant device via the adapter pipe 24. The second delivery device 32 is connected to a thermostat (not shown in the figure), so that the fluid control valve 20 delivers refrigerant to the thermostat via the second delivery device 32. However, when moving the work machine, the fluid control valve 20 of the refrigerant device must be closed. The operator can rotate the anti-leakage part 23. The second joint 236 of the anti-leakage part 23 is displaced outward along the first axis A on the first joint 218 of the valve 21 and removed. The operator can then use a wrench (not shown) to insert into the first chamber 214 of the valve 21 and insert the driving part 222 of the valve plug 22 to drive it to rotate. The external thread 223 of the valve plug 22 moves along the internal thread 2141 of the valve 21 and moves into the first chamber 214, causing the stop part 221 of the valve plug 22 to be embedded and closed in the second chamber 215 of the valve 21. The valve plug 22 itself then closes the third chamber 216, thereby closing the fluid control valve 20. Please refer to Figure 6. After the moving machine is completed, the operator uses a wrench (not shown) to rotate the valve plug 22 outward. The valve plug 22 itself leaves the opening of the third chamber 216 of the valve 21 and the stop part 221 leaves the opening of the second chamber 215, so that the valve plug 22 opens the second chamber 215 and the third chamber 216 of the valve 21. The valve 21 uses the communicating second chamber 215 and third chamber 216 to transport the refrigerant of the first conveyor 31 to the second conveyor 32 and the thermostat (not shown) via the transfer pipe 24. To effectively prevent refrigerant leakage from valve 21, the operator screws the second joint 236 of the anti-leakage component 23 onto the first joint 218 of valve 21, and gradually moves the anti-leakage component 23 toward valve 21. Because the bearing surface 2351 of the anti-leakage component 23's sealing portion 235 is relative to the pushing portion 217 of valve 21, during the movement of the anti-leakage component 23, the bearing surface 2351 of the sealing portion 235 will adhere to the pushing portion 217 of valve 21 and the opening of the first chamber 214, and withstand the external force pushed by the pushing portion 217. 5. The connecting part 234 is pulled in the direction of the force. The connecting part 234 is bent and deformed by the external force, so that the stop seal part 235 is displaced along the first axis A toward the relief part 237. When the staff uses inspection tools or visually observes that the mark 2352 (i.e. the side) of the stop seal part 235 is flush with or exceeds the preset identification position C of the anti-leakage component 23, they can quickly know that the anti-leakage component 23 has reliably and tightly sealed the first chamber 214 of the valve 21. During the process of the fluid control valve 20 conveying refrigerant, the leakage is effectively prevented and energy costs are saved, and the environmental quality of the plant area can be improved. Referring to Figure 7, the anti-leakage component 23 of the fluid control valve 20 has a stop-seal portion 235 with a colored ring mark 2354 on the outer ring surface 2353 of one of the areas of the relief portion 237. The stop-seal portion 235 of the anti-leakage component 23 can withstand the push of the valve 21's push portion 217 and be displaced along the first axial direction A. When the colored ring mark 2354 of the stop-seal portion 235 exceeds the preset identification position C, the operator can visually and quickly know that the anti-leakage component 23 has effectively and tightly sealed the first chamber 214 of the valve 21, thus preventing leakage. Please refer to Figures 4-6 and 8. The electronic component processing machine includes a machine base 40, a feeding device 50, a receiving device 60, a processing device 70, the refrigerant device 30 of this invention, a transfer device 80, and a central control device (not shown).

The at least one fluid control valve 20 is disposed on the side of the machine 40 and includes a valve 21, a valve plug 22 and a leak-proof component 23. The third chamber 216 of the valve 21 is connected to the first conveyor 31, and the second chamber 215 is connected to the second conveyor 32 via a transfer pipe 24. The second conveyor 32 is then connected to the temperature controller 73 of the operating device 70, so that the fluid control valve 20 can supply or stop the refrigerant from the refrigerant receiver 33 to the temperature controller 73. The transfer device 80 is mounted on the machine base 40 and is provided with at least one transferor for transferring electronic components.
