A waterproof and dustproof quick plug and its working method

Abstract

The present invention discloses a waterproof and dustproof quick plug and a working method thereof. The waterproof and dustproof quick plug comprises a female joint and a male joint. The female joint is arranged on a quick replacement tray. The male joint is arranged on a quick replacement chuck. The female joint is provided with a copper contact head. The male joint is provided with a probe matched with the copper contact head. The copper contact head and the probe are respectively connected with a control line and are sealed by silica gel. Due to the arrangement of the quick replacement tray and the quick replacement chuck, the automatic plugging of the male joint and the female joint is realized. The quick replacement chuck is provided with a nozzle for cleaning the male joint and the female joint. Due to the arrangement of the quick replacement tray and the quick replacement chuck, the automatic plugging of the male joint and the female joint is realized. Meanwhile, the quick replacement chuck is provided with the nozzle for cleaning purpose. Therefore, the functions of automatic plugging, automatic switching-on and automatic switching-off are realized. Residual water stains on the surface of a mechanism are prevented from flowing into the plug, so that the plug is dustproof and waterproof in the separated state.

Description

technical field [0001] The invention belongs to the technical field of electrical automation, and in particular relates to a waterproof and dustproof quick plug and a working method. Background technique [0002] In the automatic production unit of a certain workpiece, in the fixture implemented according to the layout of the processing technology, an electromagnetic suction cup needs to be installed on the quick-change pallet to realize the clamping and positioning of the workpiece. The positioning between the quick-change pallet and the machine tool is realized by the quick-change pallet and the quick-change chuck. During the processing, the quick-change pallet needs to be operated between multiple machine tools, and each machine tool needs to be clamped once or more times. Tightening and loosening operations; that is, the electromagnetic force chuck needs to perform one or more charging and demagnetization operations on each machine tool, so a plug device similar to a qui...

AI Technical Summary

Problems solved by technology

The control line voltage of the electromagnetic force chuck is higher than the (human body) safety voltage. Considering safety issues and good line contact, the plug is required to have external insulation, dustproof (metal chips), and waterproof (cutting fluid) during processing. function, there are various types of waterproof plugs on the market, and the standard aviation plugs are also waterproof, but most of them need to be manually plugged and tightened, and most of them are waterproof when they are connected, and the plugs are waterproof when they are disconnected. Contacts are exposed

[0003] Most of the existing waterproof plugs need to be plugged and tightened manually, which is not convenient for realizing automation. It is only dustproof and waterproof after it is connected and tightened. After the contact is disconnected, the contact leaks, and there is no waterproof and dustproof effect.
