Description

Technical Field

[0001] This utility model relates to the field of metal post-processing cleaning technology, specifically to an automatic air washing device based on photoelectric sensing and PLC control. Background Technology

[0002] The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar daily-use metal products, etc. With social progress and technological development, metal products are used more and more widely in various fields of industry, agriculture and people's lives, and create greater and greater value for society. However, during the metal processing process, dust and debris generated during processing often remain on the surface of the workpiece, such as aluminum die castings, machined parts and other workpieces.

[0003] Some existing cleaning devices require operators to manually place the workpiece at the bottom of the cleaning device before cleaning. This does not allow for automatic transfer of the workpiece. Furthermore, during the air washing operation, the dust generated during cleaning will disperse inside the cleaning hood and may re-adhere to the workpiece surface after the air washing operation is completed. The dust cannot be collected, which affects the air washing effect of the workpiece. Utility Model Content

[0004] In view of this, the present invention provides an automatic air washing device based on photoelectric sensing and PLC control, which can not only realize the automatic transfer of workpieces and improve work efficiency, but also collect and treat dust to ensure the air washing effect of workpieces.

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic air washing device based on photoelectric sensing and PLC control, including an air washing table, on which workpieces are placed, and several air blowing ports for air washing the workpieces. A moving mechanism for transferring the workpieces is provided on the air washing table, facilitating the loading and unloading of workpieces by an external automatic transfer robot. The moving mechanism includes a first cylinder mounted on the air washing table, with a connecting plate connected to the telescopic end of the first cylinder. A slide for placing the workpiece is provided on the connecting plate, with the workpiece positioned above the slide. The operator... The workpiece can be moved back and forth on the slide by the operation of the first cylinder. The slide is equipped with a dust discharge hole for dust removal and several auxiliary flow channels for dust removal. The auxiliary flow channels can further ensure negative pressure suction of dust in the slide. The bottom of the air washing table is equipped with a suction pipe connected to an external collection device for negative pressure dust suction. The dust and debris from the air washing can be drawn into the suction pipe through the dust discharge hole. The air washing table is equipped with a side plate to limit the flow of dust. The side plate can prevent some dust from spreading outward when the dust is drawn into the suction pipe.

[0006] The side plate is symmetrically equipped with slide rails, and several sliders are installed on the slide table. The sliders are evenly distributed on the bottom of the slide table and slide on the slide rails, which facilitates the smooth sliding of the slide table when the workpiece is moved back and forth.

[0007] The slide is equipped with a photoelectric sensor to detect whether the workpiece is in place. The photoelectric sensor is connected to the PLC processing system. After the photoelectric sensor detects that the workpiece is in place, the PLC processing system controls the air washing operation.

[0008] The air washing table is equipped with a protective mechanism to prevent dust diffusion. The protective mechanism includes a second cylinder installed on the air washing table. The telescopic end of the second cylinder is connected to a cleaning cover for covering the slide table. The cleaning cover is moved down by the second cylinder to cover the displaced workpiece.

[0009] The air washing table is equipped with a fixed cylinder, and a sliding rod that is fixed to the washing hood is slidably installed inside the fixed cylinder to ensure the stability of the washing hood when it moves.

[0010] The slide table has a groove to facilitate the lowering of the cleaning cover to cover the workpiece after it has been moved into place.

[0011] The air inlet is connected to an external air blowing device via an external air pipe for cleaning the workpiece. The air inlet is located on the cleaning hood, and the blowing time and blowing pressure of the air blowing device are controlled by a PLC processing system.

[0012] The suction hose can provide negative pressure through the vacuum cleaner to draw the blown-out dust into the collection device.

[0013] The slide is equipped with a support rod, and the support rod is equipped with a placement platform for placing workpieces, which facilitates the picking and placing of workpieces by the automatic transfer robot.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. When this utility model is used, it can not only realize the automatic transfer of workpieces, significantly reduce manual intervention and improve work efficiency, but also collect and treat dust, block the dust diffusion path, avoid secondary pollution, and ensure the air washing effect of workpieces.

[0016] 2. When this utility model is used, after the photoelectric sensor detects that the workpiece is placed in place, the PLC processing system controls the air washing operation of the workpiece in real time.

[0017] 3. When this utility model is used, the protective mechanism is used to prevent dust from spreading outward. The workpiece after being moved can be covered by the downward movement of the cleaning hood. The groove of the sliding table cooperates with the cleaning hood to achieve rapid sealing.

[0018] 4. When using this utility model, the air blowing port is connected to an external air blowing device through an external air pipe for blowing and cleaning workpieces. The blowing time and blowing pressure of the air blowing device are controlled by a PLC processing system to avoid gas waste and reduce energy consumption.

[0019] 5. When this utility model is used, the suction pipe can provide negative pressure through the vacuum cleaner to suck the dust blown out into the collection device, reducing air pollution and overcoming the problem of secondary dust adhesion. Attached Figure Description

The auxiliary flow channels 703 can further ensure the negative pressure suction of dust in the slide table 203. The bottom of the air washing table 100 is provided with a suction pipe 702 connected to an external collection device for negative pressure dust suction. The dust and debris from the air washing can be drawn into the suction pipe 702 through the dust discharge hole 701. The air washing table 100 is provided with a side plate for limiting the direction of dust flow. The side plate can prevent some dust from spreading outward when the dust is drawn into the suction pipe 702.

[0033] It is worth mentioning that the telescopic end of the first cylinder 201 is equipped with a fastening nut, which is used to connect and fix the telescopic end to the connecting plate 202.
