Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0032] Example 1

[0033] Reference Figure 1 A dust collection device for assembling aircraft parts includes an electrical control cabinet, multiple dust collection components, and a gas storage component.

[0034] The electrical control cabinet includes a touch-screen control display, buttons, an air switch, a DC regulated power supply module, a PLC control module, intermediate relays, and a pneumatic valve island module. The output of the air switch is connected to the input of the DC regulated power supply module. The output of the DC regulated power supply module is connected to the PLC control module, intermediate relays, pneumatic valve island module, touch-screen control display, and buttons. The PLC control module is connected to the touch-screen control display, buttons, and intermediate relays. The intermediate relays are connected to the input of the pneumatic valve island module. The buttons include control buttons and display buttons.

[0035] The dust collection assembly includes a vacuum transmitter, a dust collection pipe, and a collection box. One end of the vacuum transmitter is equipped with a dust recovery port, which is connected to the collection box via a pipe. The collection box is used to collect dust and aluminum shavings. The other end of the vacuum transmitter is connected to the dust collection pipe via an interface, which can be configured with various types. The dust collection pipe is used to absorb dust, aluminum shavings, and other debris. The vacuum transmitter is equipped with a pressure inlet, which is connected to the output end of the pneumatic valve island module via a pipe. The pneumatic valve island module is controlled by the electrical cabinet, thereby controlling the on / off function of the vacuum transmitter.

[0036] The gas storage assembly includes a check valve, a pressure switch, a gas storage tank, and a manual ball valve switch. The check valve is a one-way solenoid valve used to input compressed air. One end of the pressure switch is connected to the one-way solenoid valve, and the other end of the pressure switch is connected to the inlet end of the gas storage tank. The outlet end of the gas storage tank is connected to one end of the manual ball valve switch, and the other end of the manual ball valve switch is connected to the input end of the pneumatic valve island module through a pipeline.

[0037] A one-way solenoid valve is used to control the unidirectional flow of compressed air, which avoids air leakage and reduces energy waste.

[0038] The dust collection device is composed of an electrical control cabinet, a dust collection component, and a gas storage component, achieving miniaturization, lightweight design, good mobility, low carbon footprint, and environmental friendliness. The output air source of the pneumatic valve island module is controlled by the PLC control module of the electrical control cabinet, achieving controllability.

[0039] The working process of the aforementioned dust collection device used for aircraft component assembly is as follows:

[0040] The electrical control cabinet connects the 220V household AC power supply to the input terminal of the air switch. The output terminal of the air switch connects the AC power supply to the input terminal of the DC regulated power supply module. The output terminal of the DC regulated power supply module outputs 24V DC power to the PLC control module, intermediate relays, pneumatic valve island module, touch control display screen and buttons to provide 24V.

[0041] A DC regulated power supply is used to convert 220V high-voltage AC power into 24V low-voltage DC power, enabling high-voltage control and improving safety.

[0042] Compressed air is sequentially delivered to the gas storage tank via a one-way solenoid valve and a pressure switch as a compressed air source. The one-way solenoid valve is the input switch for the compressed air source to enter the gas storage tank, and the manual ball valve is the output switch for the compressed air source to exit the gas storage tank. The pressure switch is used to detect the pressure in the gas storage tank in real time. The electrical control cabinet controls the opening and closing of the one-way solenoid valve based on the pressure detected by the pressure switch in real time, thereby realizing automatic compensation of the compressed air source.

[0043] When the control button for the one-way solenoid valve is pressed, the electrical control cabinet is powered on, the touch screen control display and PLC control module are powered on, and the one-way solenoid valve of the gas storage component is opened, and compressed air begins to be delivered to the gas storage tank.

[0044] During the vacuuming process, the control cabinet determines whether to supply compressed air based on the gas pressure in the gas storage tank. When the pressure switch of the gas storage component detects that the pressure in the gas storage tank reaches 0.7 MPa, the control cabinet closes the one-way solenoid valve and stops supplying compressed air to the gas storage tank. When the pressure switch detects that the pressure in the gas storage tank is less than 0.5 MPa, the control cabinet opens the one-way solenoid valve and continues to supply compressed air to the gas storage tank. This forms a control cycle, realizing automatic compensation of the compressed air source and reducing energy waste.

[0045] A pressure switch is used to monitor the gas pressure inside the gas storage tank in real time, which effectively prevents the gas storage tank from being filled with compressed gas for a long time, resulting in excessive pressure and explosion.

[0046] When the control button for the working mode of the pneumatic valve island module is pressed, the PLC control module controls the output air source of the pneumatic valve island module according to the selected working mode. The pneumatic valve island module combines multiple dust collection components according to the selected working mode. Different combinations of dust collection components will generate different air pressures and different suction forces to perform multi-directional and multi-angle dust collection.

[0047] Multiple vacuuming components are used in combination to perform multi-directional and multi-angle vacuuming, improving vacuuming efficiency and reducing vacuuming energy consumption.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
