Description

Technical Field

[0001] The utility model relates to the field of gas path distribution blocks, in particular to a gas path distribution block with a pressure regulating valve. Background Art

[0002] In automated production lines, the gas distribution block is a key component responsible for distributing gas to different actuators, such as cylinders and vacuum cups. These actuators rely on precise air pressure to achieve accurate movements. Traditional gas distribution systems usually include complex air pipe connections and multiple independent control valves. These systems are relatively cumbersome to install, debug, and maintain. Traditional gas distribution systems are composed of many scattered components, resulting in overall system complexity and difficulty in installation and debugging. The combination of multiple independent components makes the system occupy a large space, which is not conducive to a compact production line layout. The complex system structure means a higher failure rate and more frequent maintenance work, which increases operating costs. In traditional systems, air pressure adjustment usually needs to be performed separately at multiple locations, which is cumbersome to operate and difficult to achieve precise control.

Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0043] like Figures 1 to 6 As shown, an embodiment of the present utility model provides a gas distribution block with a pressure regulating valve, comprising:

[0044] Gas distribution block 1 and pressure regulating valve 2;

[0045] The air distribution block 1 is provided with a first air inlet 11, a second air inlet 12 and a clamp connection port 13;

[0046] The pressure regulating valve 2 is connected to the first air inlet 11;

[0047] The second air inlet 12 is connected to the air distribution block vacuum unit 4;

[0048] The clamping jaw connection port 13 is connected to the clamping jaw;

[0049] A core valve 3 is provided in the air path distribution block 1 , and the core valve 3 is communicated with the first air inlet 11 , the second air inlet 12 and the clamp connection port 13 .

[0050] In the embodiment of the present invention, the air path distribution block 1 serves as the core component of the entire system, centrally managing the positive and negative pressure air paths; through the first air inlet 11 and the second air inlet 12, the system can be conveniently connected to the positive pressure gas source and the air path distribution block vacuum unit 4, thereby simplifying the layout and maintenance of the air path; the pressure regulating valve 2 is connected to the first air inlet 11, and can accurately adjust the pressure of the positive pressure gas entering the air path distribution block; enabling the system to flexibly adjust the air pressure according to actual needs, ensuring that the actuators such as the gripper work under appropriate pressure, which not only ensures work efficiency, but also avoids damage caused by excessive pressure; the second air inlet 12 is connected to the air path distribution block vacuum unit 4, and can generate a strong negative pressure suction at the gripper connection port 13; enabling the gripper to quickly and stably adsorb objects, improving It improves the grasping efficiency and accuracy of the automated production line; the gripper connection port 13 enables the air distribution block to be easily connected to multiple grippers or other pneumatic actuators; it not only improves the scalability of the system, but also reduces maintenance and replacement costs; the core valve 3 inside the air distribution block 1 is connected to each air inlet and connection port, playing a key regulating role; the core valve 3 can flexibly switch the air path according to the control signal to achieve rapid switching between positive and negative pressure, thereby meeting the complex process requirements on the automated production line; the air distribution block with a pressure regulating valve has design features such as centralized management of the air path, precise pressure regulation, efficient vacuum adsorption, flexible expansion, and internal core valve adjustment, which significantly improves the efficiency and stability of the automated production line, reduces maintenance costs, and provides strong support for the development of the industrial automation field.

[0051] like Figures 1 to 6 As shown, the core valve 3 is provided with a negative pressure vent 31, a positive pressure vent 32 and a return spring 33;

[0052] In use, when the return spring 33 is not stressed, the positive-pressure vent 32 is communicated with the first air inlet 11 , and when the return spring 33 is stressed, the negative-pressure vent 31 is communicated with the second air inlet 12 .

[0053] In the embodiment of the present invention, the core valve 3 realizes effective regulation of the air path pressure through its internal structural design; when the return spring 33 is in different states, it can selectively connect to the first air inlet 11 or the second air inlet 12, thereby controlling the pressure in the air path; by changing the force state of the return spring 33, the positive pressure and negative pressure vents can be flexibly switched, so that the air path distribution block can adapt to different working requirements; the air path can be quickly switched when needed to avoid damage to the system caused by overpressure or excessive negative pressure, thereby improving the safety and stability of the system; when the return spring 33 is not stressed, the positive pressure vent 3 2 is connected with the first air inlet 11; this means that the gas in the air circuit can flow in from the first air inlet 11, pass through the positive pressure vent 32, and then be output to the equipment or system requiring positive pressure; when the return spring 33 is stressed, the negative pressure vent 31 is connected with the second air inlet 12; the gas in the air circuit can flow in from the second air inlet 12, pass through the negative pressure vent 31, and then be output to the equipment or system requiring negative pressure; the air circuit distribution block with the pressure regulating valve realizes a flexible and safe air pressure regulating function through the core valve 3, and can switch between positive and negative pressure states as needed to meet the air pressure requirements of different equipment and systems.

[0054] like Figures 1 to 6 As shown, the second air inlet 12 is connected to a driving air path 15, and the driving air path 15 is connected to the core valve 3;

[0055] In use, when air is taken into the second air inlet 12 , the core valve 3 is squeezed to slide by the driving air path 15 . At this time, the return spring 33 is stressed, and the negative pressure vent 31 is connected to the second air inlet 12 .

[0056] In the embodiment of the present invention, when the second air inlet 12 starts to take in air, the gas can directly act on the core valve 3 through the specially arranged driving air path 15, causing it to slide; automatic driving and adjustment of the air path is realized, and no additional mechanical or electric driving device is required, which simplifies the system structure; since the driving air path 15 is directly connected to the core valve 3, when the second air inlet 12 takes in air, the core valve 3 can respond quickly and slide to the corresponding position, ensuring timely communication between the negative pressure vent 31 and the second air inlet 12; by integrating the driving function and the pressure regulating function in the same air path distribution block, not only the overall structure is made more compact, but also the efficiency and reliability of the air path regulation are improved; in the initial state, the return spring 33 is not stressed, and the core valve 3 is in the default position. At this time, the positive pressure vent 32 is connected to the first air inlet 11; when the second air inlet 12 starts to take in air, the gas passes through the driving air path The dynamic air path 15 flows to the core valve 3; as the gas flows, an extrusion force is generated on the core valve 3, causing it to overcome the resistance of the return spring 33 and start to slide; in the process of the core valve 3 sliding, the return spring 33 is gradually compressed, and at the same time the negative pressure vent 31 is gradually aligned with and connected to the second air inlet 12; once connected, the negative pressure gas can flow out smoothly through the negative pressure vent 31 to supply the equipment or system requiring negative pressure; when the second air inlet 12 stops intake or the pressure drops, the return spring 33 releases the stored energy and pushes the core valve 3 back to its initial position; the connection between the negative pressure vent 31 and the second air inlet 12 is cut off, and the positive pressure vent 32 is reconnected with the first air inlet 11, returning to the initial positive pressure state; the air path distribution block with a pressure regulating valve can quickly and automatically switch to a negative pressure state when needed, providing a stable negative pressure environment for related equipment or systems.

[0057] like Figures 1 to 6 As shown, the clamp connection port 13 is connected to one end of the negative pressure vent 31, the other end of the negative pressure vent 31 is connected to one end of the suction channel 16, and the other end of the suction channel 16 is connected to the second air inlet 12;

[0058] When in use, when air is taken in by the second air inlet 12, the return spring 33 is stressed, and the air path distribution block vacuum unit 4 starts to work, vacuuming the clamping jaws through the suction channel 16, the negative pressure vent 31, and the clamping jaw connection port 13 in sequence, forming a negative pressure on the clamping jaws.

[0059] In the embodiment of the present invention, through the negative pressure vent 31, the suction channel 16 and the clamping jaw connection port 13 inside the air path distribution block, it is possible to ensure accurate and stable negative pressure control of the clamping jaw when the second air inlet 12 takes in air; accurate control is very important for clamping jaw equipment that requires delicate operation; when the second air inlet 12 starts to take in air, the reset spring 33 is stressed, the air path is quickly switched, and the vacuum unit 4 of the air path distribution block quickly evacuates the clamping jaw through the suction channel 16, the negative pressure vent 31 and the clamping jaw connection port 13 in turn to form negative pressure; the efficient air path design can significantly improve the working efficiency of the clamping jaw; the air path distribution block can be widely used in various clamping jaw equipment that requires negative pressure control, such as industrial automation, robot grasping and other fields, which improves the flexibility and versatility of the equipment; in the initial state, the clamping jaw is in a loose state, the reset spring 33 is not stressed, and the negative pressure vent 31 and the clamping jaw connection port 13 are not stressed. No connected negative pressure air path is formed between the interface 13 and the suction channel 16; when the second air inlet 12 starts to take in air, the gas pushes the core valve 3 to slide through the driving air path 15, so that the reset spring 33 is subjected to force; at this time, a connected negative pressure air path is formed between the negative pressure vent 31 and the clamping jaw connection port 13 and the suction channel 16; as the second air inlet 12 continues to take in air, the negative pressure is transmitted to the negative pressure vent 31 through the suction channel 16, and further transmitted to the inside of the clamping jaw through the clamping jaw connection port 13, and the air inside the clamping jaw is extracted to form a negative pressure environment; under the action of negative pressure, the clamping jaw begins to contract and clamp the object; when the clamping jaw needs to be released, it is only necessary to stop the air intake of the second air inlet 12, the reset spring 33 will push the core valve 3 to reset, cut off the negative pressure air path, and the clamping jaw can be released under its own elastic action; the air path distribution block with a pressure regulating valve can achieve precise negative pressure control of the clamping jaw, thereby improving the working efficiency and application range of the clamping jaw.

[0060] like Figures 1 to 6 As shown, the first air inlet 11 is connected to the input end of the pressure regulating valve 2, the output end of the pressure regulating valve 2 is connected to one end of the air inlet channel 17, the other end of the air inlet channel 17 is connected to one end of the positive pressure vent 32, and the other end of the positive pressure vent 32 is connected to the clamping jaw connection port 13;

[0061] When in use, when air is taken in by the first air inlet 11, the reset spring 33 is not under force, and the gas is pressure-regulated by the pressure regulating valve 2 and then enters the clamping jaw through the air inlet channel 17, the positive pressure vent 32, and the clamping jaw connection port 13 in sequence, forming positive pressure.

[0062] In the embodiment of the present invention, the precise pressure regulating function of the pressure regulating valve 2 can ensure that a stable and appropriate positive pressure is provided to the clamping jaw when air is introduced into the first air inlet 11; stability is crucial for the precise operation and long-term use of the clamping jaw; when air is introduced into the first air inlet 11 and the return spring 33 is not under force, the air circuit quickly switches to a positive pressure state, and the gas, after pressure-regulated by the pressure regulating valve 2, flows through the air inlet channel 17, the positive pressure vent 32 and the clamping jaw connecting port 13 in sequence to enter the clamping jaw; so that the clamping jaw can be flexibly opened or maintained in an open state under the action of positive pressure; the presence of the pressure regulating valve 2 not only ensures the stability of the positive pressure, but also can prevent damage to the clamping jaw or the air circuit distribution block caused by excessive positive pressure to a certain extent, thereby improving the safety of the entire system; in the initial state, when the return spring 33 is not under force, the positive pressure vent 32 and the first air inlet 11 are connected through the pressure regulating valve 2 and the air inlet channel 17 ; When the first air inlet 11 starts to take in air, the gas is first pressure-regulated by the pressure-regulating valve 2 to ensure that the output positive pressure is stable and meets the working requirements of the clamp; the pressure-regulated gas then flows to the positive pressure vent 32 through the air inlet channel 17, and then enters the inside of the clamp through the clamp connection port 13; under the action of positive pressure, the clamp can be opened or maintained in an open state as needed; the existence of positive pressure enables the clamp to overcome external resistance and maintain a stable open state; when it is necessary to switch the air path state or stop the positive pressure supply, it can be achieved by controlling the air intake state of the first air inlet 11; once the first air inlet 11 stops taking in air, the positive pressure inside the clamp will gradually decrease, and the clamp can be reset or switched to other working states under the action of its own elasticity or other mechanisms; the air path distribution block with a pressure-regulating valve can achieve precise positive pressure control of the clamp, ensuring stable operation and flexible switching of the clamp under positive pressure.

[0063] like Figures 1 to 6 As shown, the gas path distribution block 1 is provided with a mounting clip 5, and the mounting clip 5 is used to connect with the external guide rail.

[0064] In the embodiment of the present invention, the installation buckle 5 enables the gas path distribution block 1 to be easily connected to the external guide rail, simplifies the installation process, and improves the installation efficiency; at the same time, the buckle connection method also ensures the stability and reliability of the gas path distribution block 1 on the guide rail; by installing the buckle 5, the gas path distribution block 1 can easily adapt to different installation environments and requirements, whether it is a linear guide rail or a curved guide rail, it can be installed quickly and accurately; the installation buckle 5 is usually designed to be more compact and takes up less space, which helps to save space for the overall system and makes the gas path distribution more neat and orderly; the installation buckle 5 itself does not directly participate in the formation or adjustment of the gas path, but serves as a gas path distribution block 1 is a structural component used to install and fix the gas path distribution block; therefore, when describing the gas path, we mainly focus on the air flow channel and connection port inside the gas path distribution block; the stability and reliability of the mounting clip 5 are crucial to ensuring the normal operation of the entire gas path system; if the mounting clip 5 is loose or damaged, it may cause the position of the gas path distribution block 1 to shift or vibrate, thereby affecting the sealing and smoothness of the gas path; therefore, during installation and use, it should be ensured that the connection between the mounting clip 5 and the external guide rail is firm and reliable to maintain the stability and performance of the gas path system; at the same time, regular inspection and maintenance of the status of the mounting clip 5 is also an important part of maintaining the normal operation of the gas path system.

[0065] In another embodiment, Figures 7 to 11 As shown, it also includes an array block 6;

[0066] The array block 6 is provided with a plurality of gas path distribution blocks 1 , which are arranged in sequence.

[0067] In the embodiment of the present invention, by setting up an array block 6 and sequentially arranging a number of gas path distribution blocks 1 thereon, the scale and function of the gas path system can be easily expanded; the system is made more flexible, and the number of gas path distribution blocks can be increased or decreased according to actual needs; the array block 6 brings together multiple gas path distribution blocks 1, which is convenient for unified management and maintenance; it helps to simplify wiring, reduce system complexity, and improve overall reliability; through the integration of the array block 6, space can be better planned and utilized, making the gas path system more compact and orderly; it helps to optimize the use of space inside the equipment and improve the integration of the system; on the array block 6, each gas path distribution block 1 has an independent gas path system, including a first air inlet 11, a second air inlet 12, a clamping claw, and a second air inlet 13. Key components such as the connecting port 13; the gas distribution block 1 is physically integrated through the array block 6, but the gas system of each gas distribution block is independent of each other; when the gas system needs to be expanded, only more gas distribution blocks 1 need to be added to the array block 6; each newly added gas distribution block will bring additional gas channels and control capabilities, thereby meeting more complex gas requirements; in terms of gas connection, the inlet and outlet of each gas distribution block 1 can be connected to an external gas source or equipment separately; so that each gas distribution block can independently control the equipment it is connected to, to achieve precise gas pressure regulation and operation control; the array block 6 provides an efficient expansion and management solution for the gas distribution block system with a pressure regulating valve, making the entire system more flexible, reliable and easy to maintain.

[0068] like Figures 7 to 11 As shown, the array block 6 is provided with a positive pressure air intake main path 61, the positive pressure air intake main path 61 is connected to a plurality of positive pressure air intake branches 62, and the plurality of positive pressure air intake branches 62 are connected to the first air inlets 11 of the plurality of air path distribution blocks 1;

[0069] When the array block is in use, the air inlet valve of the first air inlet 11 is closed, and the gas directly enters the channel of the first air inlet 11 from the positive pressure air inlet main path 61 and the positive pressure air inlet branch path 62 .

[0070] In the embodiment of the present utility model, by setting a positive pressure air intake main path 61 and a plurality of positive pressure air intake branches 62, the array block 6 can realize centralized air supply and efficiently distribute the gas to each air path distribution block 1; reduce gas waste and improve energy utilization efficiency; by connecting the positive pressure air intake main path 61 with a plurality of positive pressure air intake branches 62, and then respectively connecting them to the first air inlet 11 of each air path distribution block 1, the air path layout is greatly simplified, making the entire system more neat and orderly; when the array block is used, the air intake valve of the first air inlet 11 is closed, and the gas directly enters the channel of the first air inlet 11 from the positive pressure air intake main path 61 and the positive pressure air intake branch 62; ensure that the gas can reach the designated position quickly and accurately, and improve the response speed and flexibility of the system; when the array block 6 is used, the gas first enters the array block through the positive pressure air intake main path 61; The positive pressure air intake main path 61 serves as the main channel for gas and is responsible for transporting gas to each positive pressure air intake branch 62; each positive pressure air intake branch 62 is connected to the first air inlet 11 of an air path distribution block 1; when the air intake valve of the first air inlet 11 is closed, the gas will not pass through other channels inside the air path distribution block, but directly enter the channel of the first air inlet 11 from the positive pressure air intake branch 62; this ensures that the gas can be efficiently transported to each air path distribution block 1 and reduces the loss of gas during the transportation process; at the same time, since the gas directly enters the channel of the first air inlet 11, the response speed and control accuracy of the system are also improved; through the positive pressure air intake main path 61 and the positive pressure air intake branch 62, the air path distribution block array system with a pressure regulating valve realizes efficient and centralized gas supply, simplifies the air path layout, and improves the response speed and flexibility of the system.

[0071] like Figures 7 to 11 As shown, the array block 6 is provided with a negative pressure air intake main path 63, the negative pressure air intake main path 63 is connected to a plurality of negative pressure air intake branches 64, the plurality of negative pressure air intake branches 64 are all connected to a connecting pipe 65, the connecting pipe 65 is connected to the second air inlet 12 of the plurality of air path distribution blocks 1;

[0072] When in use, gas enters from the negative pressure air intake main path 63 and enters the second air inlet 12 through the negative pressure air intake branch path 64 and the connecting pipe 65 .

[0073] In the embodiment of the present invention, by setting a negative pressure air intake main path 63 and multiple negative pressure air intake branches 64, the array block 6 realizes centralized management of the negative pressure air path; this design simplifies the complex air path layout, making the entire negative pressure system easier to maintain and manage; the combination of the negative pressure air intake main path 63 and multiple negative pressure air intake branches 64 and the connecting pipe 65 provides flexible scalability; when more air path distribution blocks 1 need to be added, only the corresponding negative pressure air intake branches 64 and connecting pipes 65 need to be added; the gas enters from the negative pressure air intake main path 63, and quickly and accurately reaches the second air inlet 12 of each air path distribution block 1 through the negative pressure air intake branch 64 and the connecting pipe 65, ensuring the efficient operation and stability of the negative pressure system; when in use, the gas first enters from the negative pressure air intake main path 63 Array block 6; the negative pressure air intake main path 63 serves as the main negative pressure gas channel, responsible for evenly distributing the gas to each negative pressure air intake branch 64; each negative pressure air intake branch 64 is connected to the second air inlet 12 of the corresponding air path distribution block 1 through a connecting pipe 65; the gas flows in the negative pressure air intake branch 64 and smoothly enters the second air inlet 12 of each air path distribution block 1 through the connecting pipe 65; the gas enters the second air inlet 12, and will pass through the corresponding channels and valves according to the internal design of the air path distribution block, and finally act on the gripper and other equipment to form the required negative pressure environment; the air path distribution block array system with a pressure regulating valve realizes efficient and centralized management of the negative pressure air path, ensuring that the gas can reach the designated position quickly and accurately, thereby meeting the needs of various automated equipment for negative pressure control.
