Description

Technical Field

[0001] This invention relates to the field of vacuum generator technology, and in particular to an integrated vacuum generator and its usage method. Background Technology

[0002] The vacuum generator structure receives positive pressure air from the supply port. The airflow is guided within the generator by the opening and closing of vacuum and deactivation solenoid valves, thereby controlling the generation and deactivation of the vacuum to meet the needs of handling during production. The term "vacuum" refers to a pressure value lower than atmospheric pressure. This pressure is sufficient to generate enough suction when a vacuum suction device contacts an object to stably lift and move it. Therefore, "vacuum" is not an absolute vacuum, but rather a negative pressure value. The vacuum generator uses compressed air as its direct energy source to produce this negative pressure.

[0003] Vacuum generators currently used in the automotive automation industry generally have the following problems: 1. The generator is large in size, which is not suitable for use in certain space-constrained situations; 2. The generator structure is relatively complex, making maintenance and repair inconvenient; 3. Too many integrated functions, such as various detection functions, lead to complicated operation and high price, making them unsuitable for some simple automotive automation applications. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an integrated vacuum generator, comprising: The housing assembly includes a body, a digital display housing disposed at the upper end of the body, a cover plate disposed on the side of the body, and a generating housing disposed at the lower end of the body, wherein the generating housing is provided with a vacuum generating chamber and a silencer chamber; A vacuum generating device is detachably installed in the main body. The generating end of the vacuum generating device is connected to the vacuum generating chamber, and the exhaust end of the vacuum generating device is connected to the silencer chamber. The solenoid valve control assembly includes a solenoid valve assembly disposed in the digital display housing and a valve stem assembly disposed on the side of the body and electrically cooperating with the solenoid valve assembly. The valve stem assembly includes a vacuum valve stem connected to the intake air path control and a breaker valve stem connected to the breaker air path control. The solenoid valve assembly is configured to open / close the vacuum valve stem and close / open the breaker valve stem to switch between opening the vacuum path and breaker the vacuum path.

[0005] Furthermore, the main body includes a first accommodating body arranged horizontally and a second accommodating body arranged vertically on the side wall of the first accommodating body; The bottom of the second container is an air inlet, and above the air inlet, a first air passage for air intake and a second air passage for destruction are arranged vertically side by side along the inner cavity of the second container. The first accommodating body has a third air passage arranged laterally, and the third air passage is connected to the first air passage; The second accommodating body is further provided with a fourth air passage, which connects the second air passage and the vacuum generating chamber.

[0006] Furthermore, the vacuum generating device includes a vacuum generating tube disposed in the third air passage and a vacuum generating tube support fixedly connected to the exhaust end of the vacuum generating tube; a sealing element is provided between the vacuum generating tube and the third air passage.

[0007] Furthermore, the solenoid valve assembly includes a vacuum solenoid valve, a disruptive solenoid valve, and solenoid valve control needles electrically connected to the two solenoid valves respectively.

The vacuum valve stem is disposed in the first valve stem mounting cavity to connect / block the first air passage in the open / closed state; the disrupting valve stem is disposed in the second valve stem mounting cavity to connect / block the second air passage in the open / closed state.

[0009] Furthermore, a flow rate regulating plug is provided in the second airway.

[0010] Furthermore, the silencing device cavity is provided with a silencing core.

[0011] Furthermore, the digital display housing is also provided with a vacuum gauge circuit device, which detects the vacuum value of the vacuum generating cavity through a fifth air passage that penetrates the first accommodating body and the vacuum generating cavity.

[0012] Furthermore, the vacuum generating chamber and the silencer chamber are connected to the third air passage through the sixth air passage and the seventh air passage, respectively, and a pressure-holding diaphragm is provided on the upper end surface of the vacuum generating chamber in the area that matches the sixth air passage.

[0013] The present invention also provides a method of using the above-mentioned integrated vacuum generator, including: In operation: Positive pressure gas is supplied through the gas supply port. The vacuum solenoid valve controls the vacuum valve rod to open the first gas passage. The destruction solenoid valve controls the destruction valve rod to close the second gas passage. The positive pressure gas enters the vacuum generating device in the third gas passage through the first gas passage. The vacuum generating device acts on the vacuum generating chamber to generate negative pressure. The positive pressure gas in the vacuum generating device passes through the exhaust port and is discharged after being silenced by the silencing core in the silencing device chamber. In the damaged state: positive pressure gas is supplied through the gas supply port, the vacuum solenoid valve controls the vacuum valve rod to close the first gas passage, and the damage solenoid valve controls the damage valve rod to open the second gas passage.

[0016] 3. The vacuum generating tube of the integrated vacuum generator of the present invention is threaded onto the main body through a vacuum generating tube bracket. This structure allows for quick and easy disassembly and assembly of the vacuum generating tube, avoiding the risk of damaging other components during disassembly and assembly, simplifying maintenance and cleaning steps, and improving efficiency.

[0017] 4. In this invention, the vacuum generating tube and the pressure holding diaphragm of the integrated vacuum generator are separated.

[0027] In specific implementation, as shown in the appendix Figure 1 As shown, the solenoid valve assembly includes a vacuum solenoid valve 31, a destructive solenoid valve 32, and solenoid valve control pins 35 electrically connected to the two solenoid valves respectively.

[0028] Specifically, the first air passage 81 is provided with a first valve stem mounting cavity 811, the second air passage 82 is provided with a second valve stem mounting cavity 821, the vacuum valve stem 33 is disposed in the first valve stem mounting cavity 811 to connect / block the first air passage 81 in the open / closed state; the disrupting valve stem 34 is disposed in the second valve stem mounting cavity 821 to connect / block the second air passage 82 in the open / closed state.

The negative pressure chamber 141 generates negative pressure and thus generates suction force on the object below. The positive pressure air in the vacuum generating device 2 passes through the exhaust port, passes through the seventh air passage 87, and is discharged after being silenced by the silencing core 151 in the silencing device chamber 15. Under damaged conditions: as shown in the attached document Figure 3 As shown, the air supply port on the lower left side of the main body 11 provides positive pressure gas.
