Metal card holder detection device

Abstract

The invention discloses a metal card holder detection device which comprises a detection module and a magnet, wherein the detection module comprises a detection unit, an indicating unit and a magneticswitch; the detection unit is electrically connected with the indicating unit through the magnetic switch; when the magnetic switch is in an open state or closed state, the indicating unit gives different indication information; the magnet can slide; the magnet and the magnetic switch are arranged oppositely, and a certain distance is reserved between the magnet and the magnetic switch; if a metal card holder is arranged in a card slot during detection, the metal card holder attracts the magnet to slide to approach the magnetic switch, then the magnetic switch is closed, and the indicating unit gives the indication information that a metal card holder exists; and if no metal card holder is arranged in the card slot, the magnet does not slide and keeps static, the magnetic switch is open,and the indicating unit gives the indication information that a metal card holder does not exist. In the invention, the indicating unit can give electronic equipment the indication information whethera metal card holder exists effectively and accurately, and the detection result is accurate, reliable, quick and convenient.

Description

technical field [0001] The invention relates to a quality inspection device for electronic equipment, in particular to a metal card holder detection device for detecting the state of the metal holder of the electronic equipment. Background technique [0002] With the rapid development of electronic equipment, especially the rapid development of mobile communication technology and equipment, in order to meet the needs of people for electronic equipment, especially portable mobile terminals, more and more mobile terminals use independent The card tray is installed with SIM (Subscriber Identification Module, customer identification module) card, SD (Secure Digital Memory, secure digital storage) card, etc. During the production of mobile terminals, all mobile terminals have their own card trays, so that users can directly install the cards after purchase; in the actual production process, occasionally there will be a phenomenon that the shipped products are not equipped with ca...

Problems solved by technology

During the production of mobile terminals, all mobile terminals have their own card trays, so that users can directly install the cards after purchase; in the actual production process, occasionally there will be a phenomenon that the shipped products are not equipped with card trays. In response to this phenomenon, most of the industry does not have a special device for detection; at the same time, due to the high integration of automated production, if manual inspection is used, the work is more difficult, and the human objective factors are relatively large, and the accuracy of the inspection cannot be fully guaranteed. ; Therefore, many manufacturers ignore the second link and leave it to the follow-up detection of whether the card tray has a fault, which greatly causes waste in the production link; such as the Chinese invention patent application number: CN201610910697.5, The name is: A card tray detection method and device, which discloses a method and device for detecting whether the card tray has a fault. The premise of the detection is that the product is assumed to be equipped with a card tray. When the tray is loaded, the result will be known at this stage, resulting in the waste of resources in many previous processes, and may even cause serious technical problems that the product cannot be re-installed with the tray, which in turn leads to the scrapping of the product
