Description

Technical Field

[0001] The present invention relates to the technical field of steel plate processing, and more specifically, to a plate surface oiling device and method. Background Art

[0002] Steel plates and other plate parts generally need to be coated with anti-rust oil, especially for yoke steel plates. At present, the method of coating the surface of the yoke steel plate with anti-rust oil is generally to manually carry the steel plate to the oiling table, and then manually roll it.

For heavier steel plates, the heaviest steel plate is close to 200kg, and it is very strenuous to manually carry up and down the table and stack them. In addition, the number of products is large, and it is difficult to maintain this work intensity for a long time.

[0067] like Fig.10 As shown, the board surface oiling method provided by the present invention uses the board surface oiling device of the present invention to apply oil to the bottom surface of the board 3, and includes the following steps:

[0073] It can be seen from the above specific embodiments that the panel surface oiling device and method provided by the present invention realizes automatic handling of panels through the design of a frame-type vacuum suction cup crane combined with a first trolley and a second trolley, without the need for manual handling; by arranging an oil spraying device in the middle of the suspension beam of the frame-type vacuum suction cup crane, when the first trolley delivers the unpacked panels to the panel suction and lifting point, the vacuum suction cup sucks up the panels and translates them along the suspension beam toward the panel placement point, and during the translation process, the panels pass through the oil spraying device, and the bottom surface of the panels is sprayed with oil by the oil spraying device. The panels after oil spraying are translated by the vacuum suction cup to the second trolley at the panel placement point, and the panels after oil spraying are repackaged on the second trolley.
