[0015] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0016] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure. Example

[0017] like Figure 1-8 As shown, the present invention provides a composite solenoid valve 2 structure, including: The manifold 1 is designed to combine multiple solenoid valves 2 into a compact unit and optimize the connection between the solenoid valves 2 to shorten the length of the gas path, improve the gas path response speed, and reduce the airflow loss; the manifold 1 is internally designed with at least two through-going channels 5, and the inlet end spacing of these channels 5 is larger than the outlet end spacing to optimize the airflow path. The outlet end of the channel 5 is usually equipped with a direction-changing outlet pipe and a connecting hole for connecting to components such as the solenoid valve 2. The air source of the complete set of automation equipment supplies air through the air inlet of the manifold 1. After the air is distributed by the manifold 1, it is connected to the solenoid valve 2 from the air outlet through accessories such as pneumatic hoses and pneumatic connectors. In this way, a small amount of air source can supply multiple pneumatic components to work at the same time, improving the efficiency and reliability of the system; The vacuum pressure switch 4 is used to control and monitor the pressure state of the vacuum system, and automatically opens or closes according to the preset pressure value to ensure that the system quickly reaches and maintains the required vacuum degree. The vacuum pressure switch 4 usually contains a pressure sensing element and an electrical control element. When the pressure of the vacuum system reaches the preset value, the pressure sensing element triggers the electrical control element to open or close the circuit. In a system that requires precise control of the vacuum environment, the vacuum pressure switch 4 automatically opens or closes according to the preset pressure value; The speed regulating valve 3 includes an adjustable opening control mechanism for changing the cross-sectional area of ​​the gas channel 5 and adjusting the gas flow rate. The speed of the gas passing through the channel 5 is precisely controlled by adjusting the valve opening, thereby achieving fine adjustment of the actuator movement speed. At least three solenoid valves 2 are arranged on the manifold 1, and have the function of switching the gas path, realizing the functions of positive pressure clamping materials, rapid exhaust after release, negative pressure suction of materials and rapid vacuum breaking; The pressure sensor is connected to the solenoid valve 2 or integrated in the solenoid valve 2 unit, and is used to detect the negative pressure value in real time and feed it back to the control system to ensure the accuracy and stability of the negative pressure suction of the material. The pressure sensor contains a pressure sensing element and a signal processing circuit. When the pressure sensing element is subjected to external pressure, it converts the pressure signal into an electrical signal, and amplifies and processes it through the signal processing circuit. The pressure sensor is connected to the solenoid valve 2 or integrated in the solenoid valve 2 unit, and is used to detect the negative pressure value in real time and feed it back to the control system. This real-time monitoring and feedback mechanism can ensure the accuracy and stability of the negative pressure suction of the material. In a system that requires precise control of the negative pressure environment, such as a vacuum suction device, it can help the control system monitor the change of the negative pressure value in real time, and adjust the working state of the solenoid valve 2 as needed to maintain a stable negative pressure environment.

[0018] See also Figure 1 The solenoid valves 2 are arranged vertically in groups and installed on the manifold 1 , and the vacuum pressure switch 4 and the speed regulating valve 3 are installed between the solenoid valves 2 in the group.

[0019] The solenoid valves 2 arranged in vertical groups can more effectively utilize the space on the manifold 1, making the entire gas control system more compact and space-saving. Through reasonable arrangement and connection, the airflow path can be optimized, the loss of airflow during transmission can be reduced, and the response speed of the gas path can be improved. The vertically arranged solenoid valves 2 make maintenance and replacement more convenient because each solenoid valve 2 can be operated independently without affecting the operation of other solenoid valves 2.

[0020] See also Figures 3 to 7 The manifold 1 is provided with a channel 5 for gas flow, which optimizes the air flow path between the solenoid valves 2 and improves the efficiency and accuracy of gas path control.

[0021] Ensure that the transmission path of the gas from the inlet end to the outlet end is the shortest to reduce energy loss and improve response speed. The outlet ends should be evenly distributed on the manifold 1 to ensure that the gas can be evenly distributed to each solenoid valve 2.

[0022] Avoid interference principle: Channels 5 should avoid mutual interference to ensure smooth gas flow.

[0023] The vacuum pressure switch 4 at least includes one of a diaphragm pressure switch and a piston pressure switch.

[0024] The diaphragm pressure switch can monitor the pressure changes inside the composite solenoid valve 2 in real time, and convert these changes into electrical signals for transmission. These electrical signals are used as feedback signals to adjust the working state of the solenoid valve 2 to ensure that the pressure in the system remains within a safe and stable range; when the pressure in the system exceeds or falls below the set safety threshold, the diaphragm pressure switch will immediately trigger an alarm or cut off the circuit and other protective measures, which helps prevent equipment damage or casualties caused by abnormal pressure.

[0025] Diaphragm pressure switches can be integrated with automated control systems to achieve remote monitoring and control.

[0026] The piston pressure switch has high accuracy and stability, and can achieve precise control of system pressure. It is suitable for occasions with very strict pressure requirements, such as precision manufacturing, scientific research experiments, etc.

[0027] Moreover, piston pressure switches usually have strong heavy-load capacity and adaptability, and can maintain stable performance in harsh working environments.

[0028] The material of the busbar 1 is 6061-T651 aluminum alloy.

[0029] The high strength and toughness of 6061-T651 aluminum alloy provide a solid structural support for the manifold 1, ensuring that the manifold 1 can maintain stability and reliability when subjected to gas pressure and external loads.

[0030] The interior of the manifold 1 is designed with a precise channel 5 structure for transmitting gas from the inlet end to the outlet end. The corrosion resistance and good weldability of the 6061-T651 aluminum alloy ensure the integrity and airtightness of the channel 5 structure. The manifold 1 needs to be connected to pneumatic components such as the solenoid valve 2, so it is required to have good sealing performance.

[0031] The easy processing and polishing characteristics of 6061-T651 aluminum alloy make the connection between the manifold 1 and the pneumatic components tighter and improve the sealing performance.

[0032] The various excellent properties of the 6061-T651 aluminum alloy enable the busbar 1 to have a long service life and high reliability, which ensures that the busbar 1 can maintain stable performance and good working condition during long-term use.

[0033] Among them, the solenoid valve 2 at least includes one of a direct-acting diaphragm structure solenoid valve 2, a step-by-step direct-acting diaphragm structure solenoid valve 2, a pilot diaphragm structure solenoid valve 2, a direct-acting piston structure solenoid valve 2, a step-by-step direct-acting piston structure solenoid valve 2 and a pilot piston structure solenoid valve 2.

[0034] The direct-acting diaphragm structure solenoid valve 2 directly controls the movement of the diaphragm through electromagnetic force, thereby quickly changing the opening and closing state of the valve. Due to its relatively simple structure, this type of solenoid valve 2 has a fast response speed and is suitable for fluid control systems that require fast switching. The diaphragm structure has good sealing performance to ensure that the fluid will not leak.

[0035] The step-by-step direct-acting diaphragm structure solenoid valve 2 combines the advantages of direct-acting and pilot-operated types, and realizes the opening and closing of the valve through step-by-step control. This type of solenoid valve 2 can adapt to fluid control systems in different pressure ranges, and is particularly suitable for occasions where the medium pressure has a certain change. The step-by-step direct-acting design improves the stability and reliability of the solenoid valve 2, ensuring the normal operation of the fluid control system.

[0036] The pilot diaphragm structure solenoid valve 2 controls the opening and closing of the pilot valve through the electromagnet, and then uses the diaphragm and pressure difference principle to control the opening and closing of the main valve. The pilot control enables the solenoid valve 2 to achieve precise control, which is suitable for occasions requiring high-precision fluid control. This type of solenoid valve 2 generates low noise during operation and has little impact on the surrounding environment.

[0037] The direct-acting piston structure solenoid valve 2 directly drives the movement of the piston through electromagnetic force, thereby changing the opening and closing state of the valve. This type of solenoid valve 2 has a simple structure and is easy to maintain and repair. It is suitable for fluid control systems with low medium pressure, such as hydraulic systems, pneumatic systems, etc.

[0038] The step-by-step direct-acting piston structure solenoid valve 2 combines the advantages of direct-acting and pilot-operated types, and realizes the opening and closing of the valve through step-by-step driving. This type of solenoid valve 2 can adapt to fluid control systems with different pressure ranges and flow rates. The step-by-step direct-acting design improves the stability and reliability of the solenoid valve 2, ensuring the long-term stable operation of the fluid control system.

[0039] The pilot piston structure solenoid valve 2 controls the opening and closing of the pilot valve through the electromagnet, and then uses the piston and pressure difference principle to control the opening and closing of the main valve. This type of solenoid valve 2 has low power consumption and significant energy-saving effect. It is suitable for fluid control systems that require a larger diameter, such as petrochemical, water conservancy engineering and other fields.

[0040] It also includes a control unit for receiving a feedback signal from the pressure sensor and adjusting the working state of the solenoid valve 2 according to the signal to achieve precise gas path control.

[0041] The control unit is the core of the entire gas circuit control system, responsible for receiving feedback signals from the pressure sensor and adjusting the working state of the solenoid valve 2 according to these signals. Specifically, the functions of the control unit include: Receive analog or digital signals sent by the pressure sensor, which reflect the actual pressure in the gas circuit. According to the preset control logic or algorithm, analyze and judge the received signals to determine whether it is necessary to adjust the working state of the solenoid valve 2. According to the result of the logical judgment, send a control instruction to the solenoid valve 2 to adjust the degree of opening or closing, thereby realizing precise control of the pressure in the gas circuit.

[0042] The pressure sensor is an important part of the gas circuit control system. It is responsible for real-time monitoring of the pressure in the gas circuit and converting this information into electrical signals to send to the control unit. The functions of the pressure sensor include: continuously monitoring the pressure changes in the gas circuit, ensuring the accuracy and real-time nature of the data, converting the monitored pressure data into electrical signals for the control unit to receive and process. The pressure sensor can also be used to detect faults or abnormal conditions in the gas circuit.

[0043] The device includes at least one gripper or suction nozzle, and an air circuit control system connected to a composite solenoid valve 2 unit, for achieving accurate material placement.

[0044] The gripper or nozzle is fixed to the actuator of the automation equipment by fasteners such as bolts and nuts.

[0045] The composite solenoid valve 2 unit is fixed at an appropriate position of the equipment through a bracket, a mounting plate and other components.

[0046] When fixing, it is necessary to ensure that the relative position between the clamping jaw or the suction nozzle and the solenoid valve 2 unit is accurate in order to achieve correct air path connection and action coordination.

[0047] The gripper or the suction nozzle is equipped with a gas line interface for connecting with the gas line pipeline of the solenoid valve 2 unit.

[0048] The air channel 5 connects the air interface of the gripper or the suction nozzle with the output port of the solenoid valve 2 unit.

[0049] When using the embodiment of the present application: Positive pressure clamping material: When the solenoid valve 2 is in a positive pressure state, the material can be clamped through the air circuit. The air source is distributed to multiple solenoid valves 2 through the manifold 1. When the material needs to be clamped, the corresponding solenoid valve 2 is activated, so that the compressed air flows into the cylinder or actuator through accessories such as pneumatic hoses and pneumatic joints. The compressed air pushes the piston of the cylinder or actuator to move, thereby generating a clamping force to clamp the material.

[0050] The clamping force is stable and reliable, and is suitable for materials of various shapes and sizes. Through the precise control of the solenoid valve 2, the fast response and precise positioning of the clamping action can be achieved.

[0051] Quick exhaust after release: When the solenoid valve 2 is switched to the exhaust state, the clamping force can be quickly released and the gas in the gas path can be exhausted at the same time. When the material is clamped and moved to the specified position, the corresponding solenoid valve 2 loses power, and the position of the output port of the solenoid valve 2 is switched, so that the compressed air no longer flows into the cylinder or actuator, but is directly discharged through the exhaust port. The piston of the cylinder or actuator is reset under the action of spring force or gravity, and the material is released.

[0052] The exhaust is rapid, which reduces the return time of the cylinder or actuator and improves the working efficiency. Through the precise control of the solenoid valve 2, it can ensure that the material is accurately released at the specified position.

[0053] Negative pressure sucks materials and feedbacks negative pressure value: When the solenoid valve 2 is in a negative pressure state, materials can be sucked through the air circuit. When materials need to be sucked, the corresponding solenoid valve 2 is activated, causing the vacuum generator to generate negative pressure, which is transmitted to the suction cup or suction device through accessories such as pneumatic hoses and pneumatic joints. The suction cup or suction device clings to the surface of the material under the action of negative pressure and sucks up the material. At the same time, the negative pressure sensor can monitor the negative pressure value in real time and feed back the signal to the control system.

[0054] The suction force is stable and reliable, suitable for materials of various shapes and materials. The real-time monitoring and feedback of the negative pressure sensor can ensure the accuracy and safety of the suction action.

[0055] Quick vacuum breaking: When the material needs to be released, the solenoid valve 2 can quickly switch states to break the negative pressure environment and release the material. When the material is sucked and moved to the specified position, the corresponding solenoid valve 2 loses power, and the solenoid valve 2 switches the position of the output port, so that the vacuum generator stops generating negative pressure. At the same time, by opening the quick vacuum breaking solenoid valve 2, the gas in the suction device is quickly discharged, breaking the negative pressure state, and the suction cup or suction device releases the material under the action of losing the negative pressure.

[0056] The vacuum is broken quickly, which reduces the time of material release and improves work efficiency. Through the precise control of the quick vacuum breaking solenoid valve 2, it can ensure that the material is accurately released at the specified position to avoid material damage or dislocation.

[0057] In a conventional pneumatic system, each solenoid valve 2 and the actuator often require a relatively long pneumatic pipeline for connection, which not only increases the complexity of the system but also leads to energy loss during the gas flow process.

[0058] The present invention combines multiple solenoid valves 2 together through a manifold 1, so that the connection distance between the solenoid valve 2 and the actuator is greatly shortened. This compact layout reduces the length of the pneumatic pipeline, thereby reducing the resistance during the gas flow process.

[0059] As the connection distance is shortened, the flow time of gas in the pipeline is reduced and the energy loss is reduced accordingly. This means that the gas volume required by the system is reduced under the same working pressure.

[0060] The shortened connection distance and reduced gas volume make the gas response faster. When an action needs to be performed, the gas can quickly reach the actuator, thus shortening the execution time of the action.

[0061] The present invention integrates multiple solenoid valves 2 together through a manifold 1 to form a compact overall structure. Compared with the traditional decentralized layout, this greatly reduces the volume of the system.

[0062] The reduced size means that the space required for the system is also reduced, which is especially important for installation environments with limited space.

[0063] By saving space, more installation space can be made for other devices or components, thereby improving the flexibility and scalability of the entire system.
