Description

Technical Field

[0001] The invention relates to the technical field of vacuum generator connection, in particular to a bus type vacuum generator. Background Art

[0002] In the current technical field, vacuum generators play a vital role in many industrial applications. However, existing vacuum generators have some significant problems in control methods.

[0003] At present, most vacuum generators on the market adopt discrete control mode, and the vacuum breaking valve, vacuum generator and vacuum pressure switch are controlled separately. This leads to a large number of wiring and scattered and messy signals, which not only increases the difficulty of installation and maintenance, but also easily leads to wiring errors.

[0004] In addition, due to the dispersion of signals, it is difficult to follow the principle of proximity in detection, so the timeliness of detection cannot be effectively guaranteed. At the same time, the connection between the existing vacuum generator signal and the host computer is not timely and convenient enough, and cannot meet the needs of modern industrial automation for efficient and precise control. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a bus-type vacuum generator to solve the technical problems that vacuum generators in the prior art mostly adopt discrete control, have many wiring connections, scattered signals, untimely detection and inconvenient connection with the host computer.

[0006] To achieve the above object, the present invention provides the following technical solution: a bus type vacuum generator, comprising a vacuum breaking valve, used to realize the disconnection and closing of the circuit under vacuum state, wherein the vacuum breaking valve contains a breaking valve PCB, a signal integration PCB and a transition PCB;

[0007] It also includes a vacuum generator and a vacuum pressure switch, and the vacuum pressure switch includes a double PCB board inside;

[0008] The vacuum generator and the vacuum pressure switch are respectively located at the bottom and the top of the vacuum breaking valve, and the signals of the vacuum breaking valve, the vacuum generator and the vacuum pressure switch are all concentrated on the signal integrated PCB;

[0009] The destruction valve PCB, signal integration PCB and transition PCB are electrically connected to each other, and the double PCB board and signal integration PCB are electrically connected to each other. The PCBs inside the vacuum destruction valve, vacuum generator and vacuum pressure switch use internal addressing to achieve communication connection and adopt dial-code control.

[0010] By adopting the above technical solution, the signal transmission of the vacuum breaking valve, vacuum generator and vacuum pressure switch is concentrated on the signal integrated PCB, so as to realize the full integration of vacuum signals, including hardware and software, and the overall structure is compact, and the integration and centralized processing of all signals are realized, wherein the bus controller processing can process the signals of the vacuum breaking valve, vacuum generator and vacuum pressure switch, effectively avoiding the problem that most of the current vacuum devices are discretely controlled and the vacuum breaking valve and vacuum pressure switch are controlled separately, and at the same time effectively avoiding the problem of a lot of wiring and scattered signals.

[0011] Furthermore, the vacuum generator also includes an air intake module, and the number of air intake modules is multiple groups, which improves the overall work efficiency and work performance.

[0012] By adopting the above technical solution, the setting of multiple groups of air intake modules can flexibly adjust the air intake volume according to different work requirements, thereby improving the overall work efficiency and work performance, so that the vacuum generator can better adapt to various work scenarios.

[0013] Furthermore, the outside of the vacuum breaking valve is respectively connected to a left end plate and a right end plate, a bus controller is arranged on one side of the left end plate, the left end plate includes a controller connection port, and the controller connection port is electrically connected to the bus controller.

[0014] By adopting the above technical solution, the bus controller can realize the timely connection between the vacuum breaking valve, vacuum generator and vacuum pressure switch and the host computer, so that all signals can be transmitted to the host computer quickly and accurately through the bus, realizing precise control and real-time monitoring of the entire system.

[0015] In summary, the present invention mainly has the following beneficial effects: the present invention realizes full integration of vacuum signals, including hardware and software, by concentrating the signal transmission of the vacuum breaking valve, vacuum generator and vacuum pressure switch on the signal integrated PCB. The overall structure is compact, and the integration and centralized processing of all signals are realized. The bus controller processing can process the signals of the vacuum breaking valve, vacuum generator and vacuum pressure switch, effectively avoiding the problem that most of the current vacuum devices are discretely controlled and the vacuum breaking valve and vacuum pressure switch are controlled separately, and at the same time effectively avoiding the problem of a lot of wiring and scattered signals.

[0026] A bus type vacuum generator, such as Figure 1-Figure 7 As shown, it is mainly composed of a vacuum breaking valve 1, a vacuum generator 2 and a vacuum pressure switch 3.

[0027] The vacuum breaking valve 1 includes a breaking valve PCB 101 , a signal integration PCB 102 and a transition PCB 103 , and the vacuum pressure switch 3 includes a double PCB board 301 .

[0028] The vacuum generator 2 and the vacuum pressure switch 3 are respectively located at the bottom and the top of the vacuum breaking valve 1, so that the overall structure is more compact and occupies a smaller space volume.

[0029] The function of the vacuum breaking valve 1 is to control the opening and closing of the circuit under vacuum state to ensure the safe operation of the system.

[0030] The internal destruction valve PCB101 is used to control the switching action of the vacuum destruction valve, the signal integration PCB102 is responsible for collecting and integrating the signals of the vacuum destruction valve 1, the vacuum generator 2 and the vacuum pressure switch 3, and the transition PCB103 plays a transitional role in connection and signal transmission.

[0031] The centralized processing of these signals enables full integration of vacuum signals and improves the stability and reliability of the system.

[0032] The vacuum pressure switch 3 is used to monitor the vacuum pressure in real time and transmit the pressure signal to the signal integrated PCB 102. The dual PCB board 301 inside it enhances the stability and accuracy of signal transmission.

[0033] The main function of the vacuum generator 2 is to generate vacuum and provide the required vacuum environment for the system. At the same time, it also includes an air intake module 201, and the number of the air intake modules 201 is multiple groups.

[0034] The arrangement of multiple groups of air intake modules 201 can flexibly adjust the air intake volume according to different work requirements, thereby improving the overall work efficiency and work performance, and enabling the vacuum generator to better adapt to various work scenarios.

[0035] The outside of the vacuum breaker valve 1 is respectively connected with a left end plate 4 and a right end plate 5 to protect and support the internal components.

[0036] A bus controller 6 is provided on one side of the left end plate 4. The left end plate 4 includes a controller connection port 401, and the controller connection port 401 and the bus controller 6 are electrically connected. The bus controller 6 can realize the timely connection between the vacuum breaking valve 1, the vacuum generator 2 and the vacuum pressure switch 3 and the host computer, so that all signals can be quickly and accurately transmitted to the host computer through the bus, thereby realizing precise control and real-time monitoring of the entire system.

[0037] In actual work, when the vacuum generator 2 starts to work, the vacuum breaking valve 1 accurately controls the opening and closing of the circuit under the vacuum state through the control of the breaking valve PCB 101 according to the needs of the system;

[0038] The air intake module 201 of the vacuum generator 2 adjusts the air intake volume according to the requirements of the working scene, thereby generating a stable vacuum;

[0039] The vacuum pressure switch 3 monitors the vacuum pressure in real time and accurately transmits the pressure signal to the signal integrated PCB 102;

[0040] The signal integration PCB 102 efficiently integrates and processes the signals from different components, and then communicates quickly and stably with the host computer through the bus controller 6. The host computer accurately controls the entire system based on the received signals to ensure that the system can operate stably and reliably.

[0041] Furthermore, the present invention not only solves the problems of discrete control vacuum and vacuum detection signals in the existing market, numerous wiring connections and easy errors, but also solves the problem of proximity principle and timeliness of detection;
