Currency detection pen and manufacturing method thereof

Abstract

The invention provides a currency detection pen and a manufacturing method thereof. The currency detection pen is characterized in that: a plastic color pen sheath without a pen core is used as a shell of the currency detection pen, a hollow rubber tube of a hard sign pen core and an experimental circuit board are used as a structural support of electronic elements in the hollow pen sheath for insulation and connecting fixation, and a single copper core flexible rubber lead is connected with a mini-type ultraviolet-light currency detection lamp, a button cell and a light-touch switch; the whole circuit has four tin soldering points; the head of the currency detection lamp is arranged at the position of a pen head hole of the hollow pen sheath and protected by the pen head hole and a pen cap, and the pen cap can be taken down in use; the cell is arranged between the currency detection lamp and the switch; the switch is tightly adhered to the bottom part of a barrel-shaped tail cap of the pen sheath, a touch handle of the switch extends from a perforation in the centre of the bottom of the tail cap of the pen, and the length of the touch handle does no exceed the outer edge port of the tail cap of the pen. The switch can be taken out together with the tail cap of the pen, so that the exchange of the cell is convenient. The currency detection pen is small and portable, can be used as short-time illumination for unlocking a door at night, can identify all true and false self-proclaimed anti-ultraviolet light products such as vehicle glass films and sun glasses, can be used as the electronic manufacturing teaching courseware for middle school students and manufactured independently or massively produced in a plant.

Description

technical field [0001] The invention relates to an ultraviolet light currency detector pen and a manufacturing method thereof, which can be used for daily currency detector and electronic production teaching practice. Background technique [0002] At present, there are many pen-type money detector products on the market, most of which are chemical medicine money detector pens and ultraviolet light money detector pens. As far as the ultraviolet light banknote detection pen is concerned, most of them are banknote detection / writing dual-purpose pens with writing or lighting functions and additional ultraviolet light banknote detection functions, such as Chinese patent ZL200520117155.X and Chinese patent ZL200520125994.6 and Chinese patent ZL200720306163.8, etc. The shells and internal structures of these patented products all require special standard structure design and mold-opening production to become a valuable banknote detection tool. They lack a personalized product that...

AI Technical Summary

Problems solved by technology

The outer casing and internal structure of these patented products require special standard structural design and mold opening production in order to become a valuable banknote detection tool, and lack a personalized product that can be designed and produced by people.

In the field of school electrical teaching, especially in the field of electronic production teaching, there is a lack of electronic production teaching courseware with strong practicality and operability.
