DETAILED DESCRIPTION

[0061] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numbers in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0062] The following specific embodiments describe in detail the technical solutions of the embodiments of the present application and how the technical solutions of the embodiments of the present application solve the current problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0063] See also Figure 1-Figure 3 , an embodiment of the present application provides a pressure gas cleaning device for cleaning a workpiece, the pressure gas cleaning device comprising: a housing mechanism 1, at least one gas tank 2, a centrifugal fan 3, an air control valve group 4 and at least one air nozzle 5;

[0064] The workpiece is fixed inside the housing mechanism 1;

[0065] Gas tank 2 is used to store pressurized gas;

[0066] The centrifugal fan 3 is connected to the air control valve group 4 and the gas tank 2 respectively;

[0067] The air control valve group 4 is connected to at least one air nozzle 5, which is fixed inside the housing mechanism 1; the centrifugal fan 3 is used to output pressurized gas to the air nozzle 5 through the air control valve 41, and the air nozzle 5 is used to spray the pressurized gas onto the workpiece.

[0068] In this example, a closed environment is created for the workpiece by fixing the workpiece in the housing mechanism 1 .

[0069] The centrifugal blower 3 transmits the pressurized gas in the gas tank 2 to the air control valve group 4, which then sprays the pressurized gas onto the surface of the workpiece through the air nozzle 5 to perform gas cleaning on the workpiece. Therefore, not only can the stains and dust on the workpiece be automatically and effectively cleaned, but the surface of the workpiece will not be scratched and moisture will not be left on the workpiece, thereby improving the effect and quality of the workpiece cleaning, shortening the production cycle, and improving the transportation and circulation efficiency. At the same time, the present application also avoids the problems in the prior art of relying on manual workpiece cleaning, resulting in high workpiece handling intensity and the high risk of production safety accidents.

[0070] In a preferred embodiment, the housing mechanism 1 comprises: a frame 11, a back plate 12, a top plate 13 and two side plates 14;

[0071] The back plate 12 is fixed to the rear side of the frame 11;

[0072] The top plate 13 is fixed to the top side of the frame 11;

[0073] The two side panels 14 are fixed to the left and right sides of the frame 11 respectively.

[0074] In this example, a frame 11 is provided to ensure the overall strength of the housing mechanism 1, and a back plate 12, a top plate 13, and side plates 14 are provided to form a closed environment within the housing mechanism 1. Optionally, the frame 11 has at least one mounting seat for connecting to a workpiece via bolts.

[0075] In a preferred embodiment, the side panel 14 has at least one observation door 15 , which is rotatably connected to the side panel 14 .

[0076] In this embodiment, the observation door 15 is provided to facilitate the user to adjust the direction of the workpiece and the direction of the spray nozzle during the workpiece cleaning process, thereby ensuring that no dead corners are left during the cleaning of the workpiece.

[0077] Optionally, the observation door 15 includes: a door panel 151, at least one hinge 152 and at least one door lock 153;

[0078] The side panel 14 has a side opening, and the door panel 151 covers the side opening;

[0079] One side of the door panel 151 is rotatably connected to the side panel 14 via at least one hinge 152;

[0080] The other side of the door panel 151 is detachably connected to the side panel 14 via at least one door lock 153 .

[0081] In a preferred embodiment, the observation door 15 has at least one observation window 154 .

[0082] In this embodiment, the observation window 154 is provided so that the worker can observe the workpiece being cleaned without opening the observation door 15 .

[0083] Optionally, explosion-proof glass is used as the observation window 154. Explosion-proof glass is a special type of glass that can protect against violent impacts. It is machine-processed using special additives and an intermediate layer to give it high strength, high toughness, and impact resistance. Even when subjected to violent impacts, it is not easily broken or penetrated, thereby reducing damage to personnel and valuables.

[0084] In a preferred embodiment, the bottom of the centrifugal fan 3 has at least one I-shaped foot 31 , and the centrifugal fan 3 is fixed to the top plate 13 via the I-shaped foot 31 .

[0085] In this example, the I-shaped legs 31 are connected to the bottom of the centrifugal fan 3 to ensure the stability of the centrifugal fan 3 .

[0086] At the same time, the I-shaped foot 31 is connected to the bottom of the centrifugal fan 3 and the upper surface of the top plate 13 by bolts, so that the I-shaped foot 31 can buffer the vibration of the centrifugal fan 3 during operation, thereby reducing the vibration transmitted from the centrifugal fan 3 to the top plate 13 and reducing the operating noise of the device.

[0087] In a preferred embodiment, the air control valve assembly 4 has at least one air control valve 41 , and one air control valve 41 is connected to at least one air nozzle 5 .

[0088] In this example, the switch of the air nozzle 5 and the gas injection pressure are controlled by setting the air control valve group 4; the air control valve 41 controls at least one air nozzle 5, so that the switch of each air nozzle 5 and the pressure gas injection amount and injection pressure of each air nozzle 5 can be controlled in a targeted manner through each air control valve 41.

[0089] It should be noted that the air control valve 41 is a key component in the pneumatic control system, used to control the pressure, flow rate, and flow direction of the gas to ensure that the pneumatic actuator or mechanism can operate normally. The working principle of the air control valve 41 is based on the compressibility and fluidity of the gas. When the regulating pipeline receives a control signal from the automated control system, the air control valve 41 will adjust the flow parameters of the gas according to the signal requirements. For example, when it is necessary to increase the gas pressure, the air control valve 41 will open the corresponding channel to allow more gas to flow into the actuator; when it is necessary to reduce the gas flow, the degree of opening of the channel will be limited.

[0090] In a preferred embodiment, the pressure gas cleaning device further comprises: a switch door 6 and at least one collecting funnel 7;

[0091] The switch door 6 is fixed on the housing mechanism 1, and the switch door 6 is used to connect and disconnect the connection between the housing mechanism 1 and the outside world;

[0092] At least one collecting funnel 7 is fixed to the bottom of the housing structure 1 .

[0093] In this embodiment, the workpiece is placed into the housing mechanism 1 and transported out from the housing mechanism 1 by providing a switch door 6. A collecting funnel 7 is provided to collect dirt and dust dropped from the workpiece.

[0094] In a preferred embodiment, the switch door 6 comprises: two door bodies 61, two switch linear slides 62 and a bottom slide 63;

[0095] The front side of the housing mechanism 1 has a housing opening;

[0096] Two switch linear slides 62 are fixed on the upper side of the shell opening, and the bottom slide 63 is fixed on the lower side of the shell opening; one door body 61 corresponds to one switch linear slide 62, the top of the door body 61 is connected to the slider of the switch linear slide 62, and the bottom of the door body 61 is movably connected to the bottom slide 63.

[0097] In this example, by providing the switch linear slide 62, the technical effect of automatically moving the door body 61 on the bottom slide 63 is achieved, thereby achieving the technical effect of automatically opening and closing the switch door 6.

[0098] It should be noted that the switch linear slide 62 is an electric slide, an intelligent device consisting of a linear slide and a motor drive. Driven by a motor, the electric slide achieves linear motion along a guide rail, thereby automatically moving the workpiece linearly. The operating principle of the electric slide is that a control system receives commands, controls the motor, and transmits power to the slide through a transmission system, enabling precise positioning and movement along the linear guide rail.

[0099] In a preferred embodiment, the pressure gas cleaning device further comprises: a fixing frame 8;

[0100] The fixing frame 8 is fixed to the bottom of the frame 11, and the collecting funnel 7 is located inside the fixing frame 8;

[0101] The large opening of the collecting funnel 7 is connected to the bottom of the frame 11, and at least one collecting funnel 7 is arranged in parallel at the bottom of the frame 11;

[0102] The air control valve group 4 is fixed on the fixing frame 8 .

[0103] In this embodiment, a fixing frame 8 is provided to accommodate the collecting funnel 7, thereby ensuring that the collecting funnel 7 can be suspended in the air, and then a collecting bag or a collecting frame can be provided under the collecting funnel 7 to carry away stains and dust.

[0104] By fixing the air control valve group 4 on the fixing frame 8 , the air control valve group 4 is prevented from being affected by the vibration generated when the housing mechanism 1 cleans the workpiece, thereby ensuring the operational reliability of the air control valve group 4 .

[0105] In a preferred embodiment, the side of the fixing frame 8 has a fixing plate 81, and the air control valve group 4 is fixed on the fixing plate 81;

[0106] The bottom of the fixing frame 8 has feet 82 .

[0107] In this example, by providing the fixing plate 81 , the control panel of the air-controlled valve group 4 can face outward, so that workers can operate the air-controlled valves 41 in the air-controlled valve group 4 more easily.

[0108] By fixing the feet 82 to the ground, the stability of the device is ensured.
