[0002] Currently, the market demand for artificial intelligence and intelligent manufacturing is increasing. In the production process, position detection and purge systems play an important role, and they have both position detection and purge functions. The position detection function is a key technology to ensure that the workpiece or equipment can accurately reach the predetermined position during the production process. On the automated production line, position detection is the basis for achieving automated control. Position detection can provide real-time feedback on the actual position information of the workpiece or equipment, providing accurate data support for automated control to meet the needs of intelligent manufacturing. At the same time, the purge function can be used to remove welding residues, particulate matter, rust and other impurities inside the pipelines of the position detection and purge system, preventing these impurities from causing wear on the inner wall of the pipeline or blocking the pipeline, thereby affecting the normal flow of high-pressure fluids. It is an important measure to ensure the cleanliness and smooth flow of the pipeline system, and can achieve the purpose of improving fluid transmission efficiency, reducing energy consumption and costs, and improving production efficiency.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components.

[0039] The inventors discovered that when using a position detection and purge system to process workpieces, the system needs to simultaneously meet the working requirements of different workpieces, sometimes requiring individual position detection or purge for each workpiece. However, existing position detection and purge systems can only perform position detection or purge for each workpiece simultaneously, failing to meet the working requirements of different workpieces. Furthermore, existing position detection and purge systems have too low a flow rate of high-pressure fluid through the detection switch during purge, resulting in incomplete purge and chip intrusion into the detection port. The present system solves these two problems, enabling individual detection or high-flow purge at each workstation.

[0040] In order to solve the above problems, the inventors have proposed a system that can perform position detection and purging independently through research and development, which can realize independent detection or purging of each workpiece and achieve high-flow purging.

[0041] See Figure 1 , this embodiment provides a system that can perform position detection and purging independently, including an air source connection port 1, a two-way solenoid valve 2, at least one position sensor 3 and at least one three-way valve 4. The number of position sensors 3 and three-way valves 4 is the same, and can be selected according to the number of workpieces required. This embodiment does not specifically limit this. The position sensor 3 and the three-way valve 4 are connected in sequence to form a detection branch; when there are multiple three-way valves 4 and position sensors 3, the multiple position sensors 3 are connected in parallel, and the multiple three-way valves 4 are connected in parallel. The position sensors 3 and the three-way valves 4 are connected one by one to form multiple parallel detection branches. The air source connection port 1, the two-way solenoid valve 2 and the at least one detection branch are connected in sequence to form a detection circuit. The air source connection port 1 is connected to at least one three-way valve 4 to form at least one purge circuit.

[0042] When the two-way solenoid valve 2 is in the energized state and the three-way valve 4 is in the first connection state, the corresponding detection circuit is connected, allowing the gas delivered at the gas source connection port 1 to flow in the circuit to detect the workpiece. At the same time, the corresponding purge circuit is cut off. When the two-way solenoid valve 2 is in the energized state and the three-way valve 4 is in the second connection state, the corresponding purge circuit is connected, allowing the gas delivered at the gas source connection port 1 to flow in the circuit to perform cleaning or emptying operations to achieve the purpose of purging. At the same time, the corresponding detection circuit is cut off, which ensures that the detection circuit or the equipment connected thereto will not be interfered with during the purging operation. At the same time, the purge circuit is separated from the detection circuit and will not pass through the detection switch (such as the position sensor 3) during purging, which can ensure the gas flow rate and avoid the problem of unclean purging and chips entering the detection port, so as to achieve the purpose of improving the purging efficiency. The two-way solenoid valve 2 and the three-way valve 4 are both in the power-off state, and the corresponding purge circuit and detection circuit are cut off, and gas is not allowed to pass through the detection circuit or the purge circuit. This is used in situations such as system shutdown, maintenance, or safety isolation to ensure that the system is in a no-flow state and reduce accident risks. By setting the two-way solenoid valve 2 and the three-way valve 4 to control the detection circuit and the purge circuit, the different connection states of the two-way solenoid valve 2 and the three-way valve 4 determine the connection or cutoff state of the two circuits, solving the problem that the existing technology can only perform position detection or purge on each workpiece at the same time. This embodiment can realize separate detection or purge of each workpiece to meet the working requirements of different workpieces.

[0043] In one embodiment, see Figure 1The three-way valve 4 includes a first air inlet 41, a second air inlet 42 and an air outlet 43. The first air inlet 41 is connected to the position sensor 3, the second air inlet 42 is connected to the air source connection port 1, one end of the air outlet 43 can be connected to the first air inlet 41 or the second air inlet 42, and the other end of the air outlet 43 is connected to an external workpiece. When one end of the air outlet 43 is connected to the first air inlet 41, the two-way solenoid valve 2 is in an energized state, and the three-way valve 4 is in a first connection state, the detection circuit is connected, and the purge circuit is cut off; when one end of the air outlet 43 is connected to the second air inlet 42, the two-way solenoid valve 2 is in an energized state, and the three-way valve 4 is in a second connection state, the purge circuit is connected, and the detection circuit is cut off; when one end of the air outlet 43 is disconnected from both the first air inlet 41 and the second air inlet 42, the two-way solenoid valve 2 and the three-way valve 4 are in an off-power state, and the purge circuit and the detection circuit are cut off. The design of the three-way valve 4 is very flexible and can switch between different connection states as needed to meet the working requirements of different workpieces.

[0044] In one embodiment, see Figure 1 The system also includes a pressure reducing valve 5 connected between the two-way solenoid valve 2 and the position sensor 3. By setting the pressure reducing valve 5, the pressure provided by the gas source can be reduced to the pressure range required by the system or the workpiece, protecting the various components in the system from damage due to excessive pressure, and ensuring that the gas is supplied to the position sensor 3 and the external workpiece at a stable pressure, thereby improving the reliability and safety of the system.

[0045] In one embodiment, see Figure 1 The pressure reducing valve 5 includes a high-pressure chamber (not shown in the figure), a high-pressure air end (not shown in the figure), a low-pressure chamber (not shown in the figure) and a gas outlet end (not shown in the figure). The high-pressure chamber has a certain volume inside, which is used to receive the high-pressure gas from the gas source connection port 1 and temporarily store a certain amount of high-pressure gas. The two ends of the high-pressure air end are respectively connected to the gas source connection port 1 and the high-pressure chamber, which are used to introduce the high-pressure gas into the high-pressure chamber. The low-pressure chamber is a region with lower pressure, which is used to reduce the pressure of the high-pressure gas to a pressure range suitable for the system or external workpiece. The high-pressure chamber and the low-pressure chamber are connected through existing pressure reducing components (such as throttling holes, pressure reducing diaphragms, etc.) to achieve pressure reduction. The two ends of the gas outlet end are respectively connected to the low-pressure chamber and the position sensor 3, which are used to transport the reduced-pressure gas to the position sensor 3.

[0046] During operation, high-pressure gas is delivered from gas source connection port 1, which then enters the high-pressure chamber through the high-pressure air port. The gas in the high-pressure chamber then flows through the pressure-reducing member into the low-pressure chamber. During this process, the pressure of the gas is reduced, and the reduced-pressure gas flows out of the low-pressure chamber through the gas outlet port, ultimately reaching position sensor 3. During this process, regulating pressure-reducing valve 5 adjusts the pressure difference between the high-pressure and low-pressure chambers to ensure that the output gas pressure remains stable within a set pressure range. This ensures that the gas is supplied to position sensor 3 and the external workpiece at a stable pressure, thereby improving the reliability and safety of the system.

[0047] In one embodiment, the system further includes an external gas source, which serves as the system's gas supply source. The external gas source can be a compressed air tank, an inert gas tank (e.g., nitrogen, argon, etc.), or any other device capable of providing a stable gas flow. The external gas source is connected to gas source connection port 1 to provide the system with the required stable gas.

[0048] In a specific embodiment, the system also includes a flow control device, which is connected to the gas source connection port 1 and is used to control the gas flow entering the system through the gas source connection port 1. The gas flow rate can be adjusted as needed to ensure that the system can obtain appropriate gas flow in different working modes.

[0049] In a specific embodiment, the system further includes a first control unit connected to the two-way solenoid valve 2. The first control unit can be a microprocessor, PLC (programmable logic controller), or other type of control device in the prior art, which has powerful data processing and logic judgment capabilities. It is responsible for receiving external instructions or sensor signals and accurately controlling the on / off state of the two-way solenoid valve 2 according to a preset program or algorithm to achieve gas on / off.

[0050] In a specific embodiment, the system also includes at least one second control unit, which is connected to the air outlet 43 and is used to control the connection between the air outlet 43 and the first air inlet 41 or the second air inlet 42. According to the working requirements of different workpieces, the corresponding workpieces can be put into detection or purging, which can further improve the automation and adaptability of the system and meet complex working requirements.

[0051] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. The present disclosure is not limited to the precise structure described above and illustrated in the accompanying drawings, and various modifications and variations may be made without departing from its scope. The scope of the present disclosure is limited solely by the appended claims. Thus, to the extent such modifications and variations fall within the scope of the claims and their equivalents, the present disclosure is intended to include such modifications and variations.
