Description

Technical Field

[0001] This utility model relates to the field of vacuum generating equipment technology, and more specifically, to an integrated control device for a vacuum generator. Background Technology

[0002] A vacuum generator is a highly 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. In particular, when used with structures such as suction cups, they are used for the adsorption and handling of various materials, and are especially suitable for adsorbing fragile, soft, thin non-ferrous, non-metallic materials or spherical objects.

[0003] Existing vacuum generators mostly use solenoid valves and pressure sensors to control the switching of the vacuum generator. They require a power system and a continuous gas supply. When releasing, an additional gas source is needed to break the vacuum. Furthermore, the exhaust volume and vacuum level are mostly quantitatively adjustable, resulting in high overall energy consumption. They also require a relatively large number of electronic control components, which increases the product failure rate.

[0004] Chinese Patent Publication No. CN216742223U discloses a mechanical energy-saving vacuum generator, including a generator housing. A partition is provided inside the generator housing, and an expansion tube is sealed and fixedly connected to the partition. An inlet pipe and an exhaust pipe are respectively provided on both sides of the generator housing, and a fixed box is fixedly connected to the top of the generator housing. Similar mechanical vacuum generators, although they achieve flow rate regulation to some extent through adjustment components, still require the introduction of an additional air source when vacuum breaking is needed, thus lacking flexibility in adjustment. Utility Model Content

[0005] This utility model provides an integrated control device for a vacuum generator, which integrates the positive pressure gas source input and the vacuum breaking pipeline control, improving work efficiency, increasing the overall process accuracy of the equipment, and realizing the automation of the production line.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A vacuum generator integrated control device is provided, comprising a first housing, a second housing, an adapter, a vacuum breaking solenoid valve, an air intake solenoid valve, and a vacuum generating device. The first housing contains a vacuum breaking valve body and an air intake valve body. The adapter has an air source inlet, an air source outlet, and a vacuum adjustment port. The first housing also contains a first air intake channel, a second air intake channel, a third air intake channel, a fourth air intake channel, and a vacuum breaking channel. The vacuum breaking valve body has a first air inlet and a first air outlet, and the air intake valve body has a second air inlet and a second air outlet. The air intake valve body and the vacuum breaking valve body are connected through the second air intake channel. The second housing has a vacuum port connected to the vacuum generating device.

[0008] The gas source inlet, gas source outlet, first air intake channel, first air inlet, second air intake channel, and second air inlet are sequentially connected; one end of the third air intake channel is connected to the second air intake channel, and the other end is connected to the air intake channels of both the vacuum breaking solenoid valve and the air intake solenoid valve; the vacuum breaking solenoid valve has a first blowing channel connected to the vacuum breaking valve body, and the air intake solenoid valve has a second blowing channel connected to the air intake valve body; one end of the fourth air intake channel is connected to the second air outlet, and the other end passes through the adapter and connects to the air inlet of the vacuum generator provided on the second housing; one end of the vacuum breaking channel is connected to the first air outlet, and the other end passes through the adapter and connects to the vacuum port air path.

[0009] Furthermore, the vacuum breaking valve body includes a first valve seat and a first valve core. The first valve seat is divided into a first air inlet chamber and a first air outlet chamber. The first air inlet chamber is connected to the first air blowing channel. The first air inlet is located on the first air inlet chamber, and the first air outlet is located on the first air outlet chamber. When the vacuum breaking solenoid valve is closed, the first valve core slides towards the first air inlet chamber and blocks the air outlet of the first air blowing channel. At this time, the first valve core isolates the first air inlet chamber from the first air outlet chamber. When the vacuum breaking solenoid valve is open, the first valve core slides towards the first air outlet chamber. At this time, the first air inlet chamber and the first air outlet chamber are connected.

[0010] Furthermore, the intake valve body includes a second valve seat and a second valve core. The second valve seat is divided into a second intake chamber and a second outlet chamber. The second intake chamber is connected to the second blowing channel. The second intake port is located on the second intake chamber, and the second outlet port is located on the second outlet chamber. When the intake solenoid valve is closed, the second valve core slides towards the second intake chamber and blocks the outlet of the second blowing channel. At this time, the second valve core isolates the second intake chamber from the second outlet chamber. When the intake solenoid valve is open, the second valve core slides towards the second outlet chamber. At this time, the second intake chamber and the second outlet chamber are connected.

[0011] Preferably, there are multiple first air inlets, first air outlets, second air inlets, and second air outlets, and the first air inlets, first air outlets, second air inlets, and second air outlets are arranged equidistantly in their respective circumferential directions within their respective cavities.

[0012] Preferably, the vacuum regulating port of the adapter is provided with a vacuum breaking flow regulating valve, which is located on the passage of the vacuum breaking channel.

[0013] Preferably, the vacuum breaking flow regulating valve is provided with a tapered regulating rod, which can be embedded in the passage of the vacuum breaking channel.

[0014] As an improvement, the integrated control device for the vacuum generator of this utility model also includes a vacuum pressure gauge disposed outside the first housing. In one embodiment, a gas path can be led out from the vacuum breaking passage near the vacuum port and connected to the vacuum pressure gauge to monitor the operating status of the equipment at any time.

[0015] Optionally, the gas source inlet is connected to an adapter with an air inlet.

[0016] Compared with the prior art, the vacuum generator integrated control device of this utility model is set up with a first housing and a second housing connected by an adapter. The air intake valve body and the vacuum breaking valve body are installed in the first housing. At the same time, multiple air intake channels are set in the first housing to integrate the control of air intake and vacuum breaking, which improves the working efficiency, increases the overall process accuracy of the equipment, and realizes the automation of the production line.

[0017] In practical applications, the positive pressure gas source is kept open, entering through the gas source inlet. When the integrated control device of the vacuum generator performs adsorption, the vacuum breaking solenoid valve is closed, and the inlet solenoid valve is opened. At this time, the second outlet on the inlet valve body is connected by the gas path under the action of the second blowing channel. The positive pressure gas source enters the first inlet channel inside the first housing through the gas source outlet on the adapter. Since the first inlet channel, the first inlet of the vacuum breaking valve body, the second inlet channel, and the second inlet of the inlet valve body are sequentially connected, that is, the vacuum breaking valve body and the inlet valve body are conductive, the positive pressure gas source passes through the vacuum breaking valve body, then sequentially through the second inlet and the second outlet of the inlet valve body, and finally enters the vacuum generator. The fourth air inlet channel of the device generates negative pressure through the vacuum generator, which activates the adsorption device connected to the vacuum port. When the integrated control device of the vacuum generator needs to perform vacuum breaking, it opens the vacuum breaking solenoid valve. At this time, the first air outlet on the vacuum breaking valve body is opened by the air path under the action of the first blowing channel. After part of the positive pressure air source enters the first air inlet of the vacuum breaking valve body, it flows to the first air outlet and enters the vacuum breaking channel. Thus, the vacuum state of the vacuum port is broken by the rapidly flowing airflow, thereby controlling the adsorption device. When the vacuum breaking solenoid valve is closed, no gas is ejected from the first blowing channel. At this time, the first air outlet of the vacuum breaking valve body is closed, and the vacuum breaking channel will not affect the adsorption operation of the vacuum port.

[0027] like Figures 1 to 8 The image shows an embodiment of the integrated control device for the vacuum generator of this utility model. In this embodiment, Figures 2 to 6 The diagrams illustrate the directions of different airflow patterns.

[0028] like Figures 1 to 4 , Figure 8 As shown, the integrated vacuum generator control device of this embodiment includes a first housing 10, a second housing 20, an adapter 30, a vacuum breaking solenoid valve 40, an intake solenoid valve 50, and a vacuum generating device 60. The adapter 30 is provided with a gas source inlet 31, a gas source outlet 32, and a vacuum adjustment port 33; the first housing 10 is provided with a vacuum breaking valve body 11 and an intake valve body 12, and the first housing 10 is also provided with a first intake channel 13, a second intake channel 14, a third intake channel 15, a fourth intake channel 16, and a vacuum breaking channel 17. The vacuum breaking valve body 11 is provided with a first intake port 111 and a first outlet port 112, and the intake valve body 12 is provided with a second intake port 121 and a second outlet port 122; the intake valve body 12 and the vacuum breaking valve body 11 are connected through the second intake channel 14; the second housing 20 is provided with a vacuum port 21 and an exhaust port 22 connected to the vacuum generating device 60.

[0029] like Figures 2 to 4As shown, the air source inlet 31, air source outlet 32, first air intake channel 13, first air inlet 111, second air intake channel 14, and second air inlet 121 are connected in sequence; one end of the third air intake channel 15 is connected to the second air intake channel 14, and the other end is connected to the air intake channel of the vacuum breaking solenoid valve 40 and the air intake solenoid valve 50 through the air path, thereby ensuring the air source for the vacuum breaking solenoid valve 40 and the air intake solenoid valve 50. In addition, the vacuum breaking solenoid valve 40 is provided with a first blowing channel 41 connected to the vacuum breaking valve body 11, and the air intake solenoid valve 50 is provided with a second blowing channel 51 connected to the air intake valve body 12; one end of the fourth air intake channel 16 is connected to the second air outlet 122, and the other end passes through the adapter 30 and is connected to the air inlet 61 of the vacuum generator 60 provided on the second housing 20; one end of the vacuum breaking channel 17 is connected to the first air outlet 112, and the other end passes through the adapter 30 and is connected to the air path of the vacuum port 21.

[0030] In practical applications, the positive pressure gas source is kept open and enters from the gas source inlet 31. When the integrated control device of the vacuum generator performs adsorption, the vacuum breaking solenoid valve 40 is closed and the air intake solenoid valve 50 is opened. At this time, the second air outlet 122 on the air intake valve body 12 is connected by the air path under the action of the second blowing channel 51. The positive pressure gas source enters the first air intake channel 13 in the first housing 10 through the gas source outlet 32 ​​on the adapter 30. Since the first air intake channel 13, the first air inlet 111 of the vacuum breaking valve body 11, the second air intake channel 14 and the second air inlet 121 of the air intake valve body 12 are connected in sequence, that is, the vacuum breaking valve body 11 and the air intake valve body 12 are connected, the positive pressure gas source passes through the vacuum breaking valve body 11 and then passes through the second air inlet 121 and the second air outlet 122 of the air intake valve body 12 in sequence, and finally enters the connection of the vacuum generator. The vacuum generator 60 has a fourth air inlet channel 16. The vacuum generator 60 generates negative pressure, and the adsorption device connected to the vacuum port 21 works. When the integrated control device of the vacuum generator needs to perform vacuum breaking, the vacuum breaking solenoid valve 40 is opened. At this time, the first air outlet 112 on the vacuum breaking valve body 11 is opened by the air path under the action of the first blowing channel 41. After part of the positive pressure air source enters the first air inlet 111 of the vacuum breaking valve body 11, it flows to the first air outlet 112 and enters the vacuum breaking channel 17. As a result, the vacuum state of the vacuum port 21 is broken by the rapidly flowing airflow, thereby controlling the adsorption device. When the vacuum breaking solenoid valve 40 is closed, no gas is ejected from the first blowing channel 41. At this time, the first air outlet 112 of the vacuum breaking valve body 11 is closed, and the vacuum breaking channel 17 will not affect the adsorption operation of the vacuum port 21.

[0031] In this embodiment, the integrated control device for the vacuum generator is provided with a first housing 10 and a second housing 20 connected by an adapter 30. The air intake valve body 12 and the vacuum breaking valve body 11 are installed in the first housing 10, i.e., the same housing. At the same time, multiple air intake channels are provided in the first housing 10, thereby integrating the control of air intake and vacuum breaking, improving work efficiency, increasing the overall process accuracy of the equipment, and realizing the automation of the production line.

[0032] like Figure 5 , Figure 6 As shown, the vacuum breaking valve body 11 includes a first valve seat 113 and a first valve core 114. The first valve seat 113 is divided into a first air inlet chamber 115 and a first air outlet chamber 116. The first air inlet chamber 115 is connected to the first air blowing channel 41. The first air inlet 111 is provided on the first air inlet chamber 115, and the first air outlet 112 is provided on the first air outlet chamber 116.

[0033] When the vacuum breaking solenoid valve 40 is closed, positive pressure air enters sequentially from the air source inlet 31, air source outlet 32, first air intake channel 13, and first air inlet 111, impacting the first valve core 114 and causing it to slide towards the first air intake chamber 115, blocking the outlet of the first air blowing channel 41. At this time, the first valve core 114 isolates the first air intake chamber 115 from the first air outlet chamber 116, and no gas flows out of the first air outlet 112. It should be noted that, in order to facilitate the sliding of the valve core under the impact of the airflow, the part of the first valve core 114 near the first air intake chamber 115 can be made into a conical structure; at the same time, the part of the first valve core 114 near the first air outlet chamber 116 can be designed with a shape that can just separate the first air intake chamber 115 and the first air outlet chamber 116, and a sealing ring can be fitted on this structure to ensure sealing and prevent gas leakage.

[0034] When the vacuum breaking solenoid valve 40 is open, the first valve core 114 is sprayed with gas through the first air blowing channel 41. Under the impact of the gas, the first valve core 114 slides towards the first air outlet chamber 116, thereby making the first air inlet chamber 115 and the first air outlet chamber 116 connected. At this time, after part of the positive pressure gas source enters the first air inlet 111, it flows from the first air inlet chamber 115 into the first air outlet chamber 116 and enters the vacuum breaking channel 17 through the first air outlet 112.

[0035] Similar to the structure of the vacuum breaking valve body 11 described above, such as Figure 7 As shown, the intake valve body 12 includes a second valve seat 123 and a second valve core 124. The second valve seat 123 is divided into a second intake chamber 125 and a second outlet chamber 126. The second intake chamber 125 is connected to the second air blowing channel 51. The second air inlet 121 is located on the second intake chamber 125, and the second air outlet 122 is located on the second outlet chamber 126. It should be noted that... Figure 6 The second air intake chamber 125 and the second air outlet chamber 126 indicate the cavity structure inside the air intake valve body 12.

[0036] When the intake solenoid valve 50 is closed, positive pressure air enters the second valve core 124 sequentially from the air source inlet 31, air source outlet 32, first intake channel 13, first intake port 111, second intake channel 14, and second intake port 121. This air impacts the second valve core 124, causing it to slide towards the second intake chamber 125 and block the outlet of the second blowing channel 51. At this time, the second valve core 124 isolates the second intake chamber 125 from the second outlet chamber 126, and no gas flows out of the second outlet port 122. It should be noted that, in order to facilitate the sliding of the valve core under the impact of the airflow, similar to the first valve core 114 of the vacuum breaking valve body 11, the part near the second intake chamber 125 can be made into a conical structure. At the same time, the part of the second valve core 124 near the second outlet chamber 126 can be designed to precisely separate the second intake chamber 125 and the second outlet chamber 126, and a sealing ring can be fitted on this structure to ensure sealing and prevent gas leakage.

[0037] When the intake solenoid valve 50 is open, the intake solenoid valve 50 sprays gas onto the surface of the second valve core 124 through the second blowing channel 51. Under the impact of the gas, the second valve core 124 slides towards the second outlet chamber 126, thereby making the second intake chamber 125 and the second outlet chamber 126 connected. At this time, the positive pressure gas source enters through the vacuum breaking valve body 11 from the second outlet port 122, flows from the second intake chamber 125 into the second outlet chamber 126, and enters the fourth intake channel 16 through the second outlet port 122. The gas continues to flow to the vacuum generator 60 to work.

[0038] The integrated vacuum generator control device of this embodiment controls the opening and closing of the solenoid valve in the manner described above, thereby controlling the flow direction of the gas source. In order to ensure uniform distribution and rapid flow of air, multiple first air inlets 111, first air outlets 112, second air inlets 121, and second air outlets 122 can be provided, and these first air inlets 111, first air outlets 112, second air inlets 121, and second air outlets 122 are arranged equidistantly circumferentially in their respective cavities.

[0039] In this embodiment, the integrated vacuum generator control device enables convenient and rapid adjustment of the vacuum flow rate, such as... Figure 1 , Figure 2 and Figure 8 As shown, a vacuum breaking flow regulating valve 70 is provided at the vacuum regulating port 33 of the adapter 30, and the vacuum breaking flow regulating valve 70 is disposed in the passage of the vacuum breaking channel 17. In a preferred embodiment, the vacuum breaking flow regulating valve 70 is provided with a tapered adjusting rod 71, which can be inserted into the passage of the vacuum breaking channel 17.

[0040] In embodiments of this utility model, such as Figure 1 As shown, the integrated control device for the vacuum generator can also have a vacuum pressure gauge 80 installed outside the first housing 10. In one embodiment, a gas path can be led out from the passage of the vacuum breaking channel 17 near the vacuum port 21 and connected to the vacuum pressure gauge 80 to monitor the operating status of the equipment at any time. Furthermore, as... Figure 1 and Figure 8 As shown, an adapter 34 with an air inlet 341 can also be connected to the air source inlet 31 to facilitate the connection of the air path.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
