Description

Technical Field

[0001] This utility model relates to the field of vacuum equipment technology, and in particular to a highly integrated protocol-type vacuum valve island. Background Technology

[0002] A vacuum generator is a new type of efficient, clean, economical, and compact vacuum component that uses a positive pressure air source to generate negative pressure. This makes it very easy and convenient to obtain negative pressure in places where compressed air is available, or in a pneumatic system where both positive and negative pressure are required simultaneously. Vacuum generators are widely used in industrial automation in fields such as machinery, electronics, packaging, printing, plastics, and robotics.

[0003] If multi-channel vacuum is required, multiple integrated vacuum generators need to be stacked side by side horizontally. Each vacuum generator needs to be independently connected to a positive pressure gas pipe and a control device, which results in excessive size and complex piping and wiring. In the existing technology, in order to reduce size and piping, multiple vacuum generators are often connected to form a vacuum valve island. Only the valve island needs to be connected to the positive pressure gas pipe to supply gas to all vacuum generators.

[0004] In existing vacuum valve islands, the solenoid valve used for vacuum control is often positioned on the same straight line as the corresponding vacuum generator. Therefore, the solenoid valve for vacuum control is mounted on the end face of the valve island. To reduce overall size, the valve island is often miniaturized, resulting in less installation space for the solenoid valve. This limits the selection of smaller solenoid valves, especially those for vacuum control, leading to a decrease in airflow. Consequently, both vacuum flow and breaking flow are reduced, making it unsuitable for ultra-high-speed response and high-flow-rate vacuum applications. Furthermore, each solenoid valve for a vacuum generator needs to be connected separately to the control device, requiring complex wiring that is prone to errors. Therefore, improvements are necessary. Utility Model Content

[0013] In a further technical solution, the vacuum filter includes filter cotton and a seal. The filter cotton is fixedly installed on the seal and passes through the third connecting air passage. The inner wall of the filter insertion hole is provided with internal threads, and the seal is threadedly connected to the filter insertion hole.

[0014] In a further technical solution, air supply plates are respectively provided on the left and right sides of the manifold. Each air supply plate is provided with at least one air supply channel and at least one air supply connector connected to the air supply channel. The first air supply channel and the second air supply channel pass through the manifold laterally. The air supply channel of the first air supply plate is connected to the first air supply channel. The first air supply plate seals the second air supply channel. The air supply channel of the second air supply plate is connected to the second air supply channel. The second air supply plate seals the first air supply channel.

[0015] In a further technical solution, both the left and right ends of the first and second air supply channels are connected to the air supply channels of the two air supply plates.

[0016] In a further technical solution, the volume of the first solenoid valve is smaller than that of the second solenoid valve.

[0017] In a further technical solution, the manifold includes a vacuum section, an output section, and a cavitation section. The cavitation section is formed on the rear part of the upper end face of the vacuum section, and the output section is formed on the front side of the lower part of the vacuum section. A first solenoid valve is disposed on the upper end face of the cavitation section, a second solenoid valve is disposed on the front side of the vacuum section and located above the output section, a vacuum tube is disposed on the front side of the output section, a vacuum generator is disposed on the lower part of the vacuum section and located behind the output section, a first air supply channel is disposed on the cavitation section, and a second air supply channel is disposed on the vacuum section.

[0018] In a further technical solution, the cavitation section is provided with multiple first mounting slots at intervals along the transverse direction, and each first mounting slot penetrates the manifold along the longitudinal direction.

Each first socket is electrically connected to each first solenoid valve, and each second socket is electrically connected to each second solenoid valve through each valve connection line.

[0022] The advantages of this utility model compared with the prior art after adopting the above structure are: the vacuum generator, vacuum and vacuum breaking solenoid valves, pressure sensors, solenoid valve control devices and vacuum filters are highly integrated into a manifold to form a vacuum valve island, which optimizes the spatial layout, reduces the volume and height of the overall structure, and reduces the weight, making it suitable for high-speed compact motion mechanisms.

[0023] The second solenoid valve for controlling the vacuum is placed on the side of the manifold, which increases the installation space of the second solenoid valve without increasing the volume of the manifold, thereby increasing the volume of the second solenoid valve and improving the vacuum flow rate and response speed.

[0024] The second solenoid valve, pressure sensor, vacuum tube, and vacuum filter are all arranged around the vacuum generator, thereby reducing the airflow path length and pressure loss, enabling it to provide a larger vacuum flow rate within a limited volume, and have a shorter vacuum formation and pressure detection response time to meet the needs of ultra-high-speed application scenarios.

[0025] The solenoid valve control device is located between each first solenoid valve and each second solenoid valve, which shortens the length of the connection line between the solenoid valve and the solenoid valve. Each pressure sensor is directly electrically connected to the pressure PCB board. The pressure PCB board and the solenoid valve control device communicate and control directly through the protocol. The control device does not need to connect each pressure sensor and each solenoid valve one by one, which reduces interference, reduces the number of external connection cables, simplifies the wiring structure, reduces the wiring error rate, and improves reliability and stability.

[0026] The vacuum filter is installed independently and exposed on the manifold, eliminating the need to disassemble the entire vacuum valve island for cleaning and replacement, thus saving maintenance time and costs. Attached Figure Description

[0044] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0045] A highly integrated protocol-based vacuum valve island, such as Figures 1 to 7As shown, the system includes a manifold 1, a solenoid valve control device 7, multiple first solenoid valves 51, multiple second solenoid valves 52, and multiple vacuum generators 53. The first solenoid valves 51 are arranged side-by-side in the transverse direction on the upper surface of the manifold 1, and the second solenoid valves 52 are arranged side-by-side in the front side of the manifold 1. The solenoid valve control device 7 is located between the first solenoid valves 51 and the second solenoid valves 52, and extends transversely through each of the first solenoid valves 51 and the second solenoid valves 52. Each first solenoid valve 51 and each second solenoid valve 52 is electrically connected to the solenoid valve control device 7. Multiple downward-facing vacuum vents 4 are arranged in the transverse direction on the lower rear surface of the manifold 1. Each vacuum vent 4 is vertically arranged, and each vacuum generator 53 is inserted into each vacuum vent 4. At the lower part, the manifold 1 has a first connecting air passage 21 between the upper end of each vacuum vent 4 and the outlet end of each first solenoid valve 51. The manifold 1 has a second connecting air passage 22 between the middle of each vacuum vent 4 and the outlet end of each second solenoid valve 52. The manifold 1 has a first supply air passage 31 for connecting the inlet end of each first solenoid valve 51 and a second supply air passage 32 for connecting the inlet end of each second solenoid valve 52 in the transverse direction. The front side of the manifold 1 has a plurality of vacuum tubes 55 in the transverse direction. Each vacuum tube 55 is located below each second solenoid valve 52. The manifold 1 has a third connecting air passage 23 between each vacuum tube 55 and the middle of each vacuum vent 4. The third connecting air passage 23 is connected to the first connecting air passage 21.

[0046] Traditional vacuum valve islands suffer from poor integration, resulting in reduced vacuum flow and response speed while minimizing size and weight, making them unsuitable for ultra-high-speed applications. This invention, however, highly integrates a vacuum generator 53, vacuum and vacuum breaking solenoid valves, and a solenoid valve control device 7 onto a single manifold 1 to form a vacuum valve island. The first solenoid valve 51 and the second solenoid valve 52 are vertically aligned, optimizing spatial layout, reducing the overall structure's volume and height, and lightening its weight. The second solenoid valve 52, used for vacuum control, is positioned on the side of the manifold 1, increasing its installation space without increasing the manifold 1's volume, thus improving vacuum flow and response speed, making it suitable for high-speed, compact motion mechanisms.

[0047] Specifically, a pressure detection device 6 is also provided on the rear side of the manifold 1. The pressure detection device 6 includes a pressure PCB board 61 and multiple pressure sensors 62. Pressure air holes 41 are opened on the rear side of the manifold 1 corresponding to the middle of each vacuum ventilation channel 4. Each pressure air hole 41 is connected to the middle of each vacuum ventilation channel 4. The detection end of each pressure sensor 62 is inserted into each pressure air hole 41. The pressure PCB board 61 is fixedly installed on the rear side of the manifold 1 and electrically connected to each pressure sensor 62. The manifold 1 also integrates a pressure detection device 6, which uses pressure sensors 62 to detect the vacuum level of each vacuum vent 4. The pressure PCB board 61 then transmits the vacuum level signals from each pressure sensor 62 to the control device via a protocol. This eliminates the need for each pressure sensor 62 to be independently connected to the control device, improving integration and reducing the number of cables. Each pressure sensor 62 is directly soldered or plugged into the pressure PCB board 61 via terminals, eliminating the need for cable connections. This results in a simple structure, low cost, and no wiring required. Each pressure sensor 62 is connected to the pressure port 41 via threads, facilitating installation. The pressure port 41 directly connects to the vacuum vent 4, thereby shortening the distance between the pressure sensor 62 and the vacuum vent 4, resulting in fast detection response and high detection accuracy.

[0048] Specifically, the front side of the manifold 1 has multiple filter insertion holes 231. The rear end of each filter insertion hole 231 is connected to the middle of each third connecting air passage 23. Each filter insertion hole 231 is located between each second solenoid valve 52 and each vacuum tube 55. A vacuum filter 54 is inserted into each filter insertion hole 231. The vacuum filter 54 extends into and passes through the third connecting air passage 23. The manifold 1 also integrates a vacuum filter 54 to filter the air and prevent external impurities from entering the manifold 1 and causing air passage blockage when a vacuum is generated.

[0049] Specifically, the vacuum filter 54 includes a filter cotton 541 and a seal 542. The filter cotton 541 is fixedly installed on the seal 542 and passes through the third connecting air passage 23. The inner wall of the filter insertion hole 231 is provided with internal threads, and the seal 542 is threadedly connected to the filter insertion hole 231. The filter cotton 541 is hollow inside, and its inner ring is connected to one side of the third connecting air passage 23. The other side of the third connecting air passage 23 communicates with the filter insertion hole 231. Figure 6 As shown, air enters the lower part of the third connecting air passage 23 from the vacuum tube 55, then enters the filter insertion hole 231, passes through the outside of the filter cotton 541 to the inner hole of the filter cotton 541, and then re-enters the upper part of the third connecting air passage 23 from the inner hole of the filter cotton 541, finally flowing to the vacuum vent 4 and being discharged through the vacuum generator 53. When replacing the filter cotton 541, only the seal 542 needs to be removed; there is no need to disassemble the entire vacuum valve island, which facilitates maintenance.

[0050] Specifically, air supply plates 8 are respectively provided on the left and right sides of the manifold 1. Each air supply plate 8 has at least one air supply channel 82 and at least one air supply connector 81 connected to the air supply channel 82. The first air supply channel 31 and the second air supply channel 32 pass through the manifold 1 laterally. The air supply channel 82 of the first air supply plate 8 is connected to the first air supply channel 31, and the first air supply plate 8 seals the second air supply channel 32. The air supply channel 82 of the second air supply plate 8 is connected to the second air supply channel 32, and the second air supply plate 8 seals the first air supply channel 31. Compressed air is connected to the air supply channel 82 through the air supply connector 81, and the compressed air is introduced into the first air supply channel 31 and the second air supply channel 32 respectively by the air supply channel 82, thereby reducing the connection pipeline between the vacuum valve island and the compressed air.

[0051] Specifically, both ends of the first air supply channel 31 and the second air supply channel 32 are connected to the air supply channels 82 of the two air supply plates 8. The first air supply channel 31 and the second air supply channel 32 are connected through the air supply channels 82 of the two air supply plates 8, which combines the two compressed air lines connected to the two air supply connectors 81, thereby increasing the intake flow rate and pressure of the compressed air.

[0052] Specifically, the volume of the first solenoid valve 51 is smaller than that of the second solenoid valve 52. By placing the second solenoid valve 51, which is used to control the vacuum, on the side of the manifold 1, the installation space for the second solenoid valve 52 is increased without increasing the volume of the manifold 1, thereby increasing the volume of the second solenoid valve 52 and improving the vacuum flow rate and response speed.

[0053] Specifically, the manifold 1 includes a vacuum section 11, an output section 12, and a cavitation section 13. The cavitation section 13 is formed on the rear part of the upper end face of the vacuum section 11, and the output section 12 is formed on the front side of the lower part of the vacuum section 11. A first solenoid valve 51 is disposed on the upper end face of the cavitation section 13, a second solenoid valve 52 is disposed on the front side of the vacuum section 11 and located above the output section 12, a vacuum tube 55 is disposed on the front side of the output section 12, a vacuum generator 53 is disposed on the lower part of the vacuum section 11 and located on the rear side of the output section 12, a first air supply channel 31 is disposed on the cavitation section 13, and a second air supply channel 32 is disposed on the vacuum section 11. Vacuum vent 4 and second connecting vent 22 are both located in the vacuum section 11, thereby shortening the distance between the second solenoid valve 52 and the vacuum generator 53. The third connecting vent 23 is located in the output section 12 and extends into the vacuum section 11, connecting to the vacuum vent 4 and the first connecting vent 21, to shorten the distance between the vacuum generator 53 and the vacuum tube 55. This reduces the airflow path length and pressure loss, making the structure more compact and further improving vacuum flow rate and response speed. The first connecting vent 21 directly connects to the third connecting vent 23 to reduce airflow bends, forming a straight connection and improving the air-breaking response speed and air-breaking flow rate. The first supply vent 31 is located close to the inlet end of each first solenoid valve 51, and the second supply vent 32 is located close to the inlet end of each second solenoid valve 52 to further shorten the airflow path. The cavitation section 13 is located at the rear of the upper end face of the manifold 1, thereby creating a cavitation between the front of the upper end face of the manifold 1 and the first solenoid valve 51 and the second solenoid valve 52, thus reducing the weight of the manifold 1; the output section 12 is located on the front side of the vacuum section 11, thereby creating an installation space between the rear side of the output section 12 and the lower end face of the vacuum section 11 to accommodate the silencing part of the vacuum generator 53, thus preventing the vacuum generator 53 from protruding.

[0054] Specifically, the cavitation section 13 has multiple first mounting slots 131 spaced apart in the transverse direction, and each first mounting slot 131 penetrates the manifold 1 in the longitudinal direction. Each first solenoid valve 51 is fixedly installed in its respective first mounting slot 131. The front side of the vacuum section 11 has multiple second mounting slots 111 spaced apart in the transverse direction, and each second solenoid valve 52 is fixedly installed in its respective second mounting slot 111. The upper end of the second solenoid valve 52 protrudes from the upper end face of the vacuum section 11 and extends to the lower or side of the first solenoid valve 51. The first solenoid valve 51 and the second solenoid valve 52 are positioned and installed through the first mounting slots 131 and the second mounting slots 111, respectively. Both the first mounting slots 131 and the second mounting slots 111 are provided with screw holes, and the first solenoid valve 51 and the second solenoid valve 52 are fixedly installed in the first mounting slots 131 and the second mounting slots 111 by screws.

[0055] Specifically, the solenoid valve control device 7 includes a solenoid valve PCB board 71 and multiple valve connection lines 72. Multiple first sockets 711 are arranged horizontally on the upper part of the solenoid valve PCB board 71, and multiple second sockets 712 are arranged horizontally on the lower part of the solenoid valve PCB board 71. Each valve connection line 72 has a plug at both ends. Each first socket 711 is electrically connected to each first solenoid valve 51, and each second socket 712 is electrically connected to each second solenoid valve 52 via the respective valve connection line 72. Each first socket 711 corresponds one-to-one with each first solenoid valve 51, and each second socket 712 corresponds one-to-one with each second solenoid valve 52, thereby shortening the length of the valve connection lines 72 and ensuring that the valve connection lines 72 are relatively parallel and do not cross, thus avoiding wiring errors. The solenoid valve PCB board 71 is directly fixed to the equipment using a bracket, without needing to be fixed to the manifold 1.

[0056] This invention, in a vacuum, such as Figure 6 As shown, the first solenoid valve 51 remains closed, and the second solenoid valve 52 connects the second supply air passage 32 and the second connecting air passage 22, causing compressed air to blow towards the nozzle of the vacuum generator 53, thereby creating negative pressure in the vacuum passage 4. External air enters the lower part of the third connecting air passage 23 through the vacuum tube 55 and then enters the filter insertion hole 231. It passes through the outside of the filter cotton 541 to the inner hole of the filter cotton 541, and then re-enters the upper part of the third connecting air passage 23 from the inner hole of the filter cotton 541. Finally, it flows to the vacuum passage 4 and is discharged through the vacuum generator 53.

[0057] When the vacuum is broken, such as Figure 7 As shown, the second solenoid valve 52 remains closed, the first solenoid valve 51 connects the first supply air passage 31 and the first connecting air passage 21, the compressed air directly enters the third connecting air passage 23, and is finally blown out by the vacuum tube 55.

[0058] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
