Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

Examples

As shown in fig. 1-2, a device for detecting multipoint metallic iron by self-driven magnetic attraction comprises a lower contact plate 4, an upper positioning plate 2 and a surface cover 1 which are sequentially arranged from bottom to top, wherein the end face of the lower contact plate 4 is provided with a contact series wire 3, and a plurality of groups of contacts 5 connected with the contact series wire 3 are respectively arranged on the series wire 3.

In this embodiment, the upper positioning plate 2 is provided with a plurality of through holes 9 corresponding to the iron piece on the bottom surface of the surface cover 1, and the iron piece on the lower end of the surface cover 1 is contacted with the contact 5 through the through holes 9, so as to realize the functions of identification and detection.

The groove 8 for installing the serial conductor 3 is arranged on the end face of the lower-layer contact plate 4, the serial conductor 3, the contact 5 and the strong magnet 6 are installed in the groove 8, the groove 8 also plays a limiting role, the positions of the serial conductor 3, the contact 5 and the strong magnet 6 arranged in the groove are ensured to be accurate, and the accuracy of a detection result is ensured.

The plurality of groups of contacts 5 are one group of contacts arranged in every two mirror images, and the lower ends of every two contacts are provided with strong magnets 6. The strong magnet 6 is covered with an insulating layer.

The lower contact plate 4 is also internally provided with a product sensor 7, and the sensing end of the product sensor 7 passes through the lower contact plate 4, is contacted with the upper positioning plate 2 and is contacted with the bottom surface of the face cover 1.

The contact 5 is L-shaped, the top of the L-shaped contact is set as a product contact point, the lower end of the L-shaped contact is connected with the strong magnet 6, and the other end far away from the strong magnet 6 is connected with the serial conductor 3.

As shown in fig. 3, 0V in the 24V circuit is connected one by one to form a loop by using the good conductive physical property of the high-quality iron piece at the bottom of the product and using the exposed part of the iron piece body as a conducting block of the copper double-contact.

The product is placed before the fine positioning plate on upper strata through the printing personnel, presses circuit switch (from the locking-type, must close by hand), can trigger white pilot lamp after NPN sensor senses the product and conveniently let the operation personnel know that the product has put in place, switch on ironware detection function voluntarily, the alarm lamp can buzzing and intermittent type red scintillation when white pilot lamp lights up, and the buzzing scintillation of alarm lamp can last to the product ironware detects passing or product take away and get away from automatic elimination when the inductor.

After a submerged rubidium magnet (insulated with copper contacts) in the lower layer senses an iron piece, magnetic force can rapidly remove a close-range iron object, because the iron piece is integrally injection molded with a product, the position of the iron piece is relatively constant after the product is fixed, the magnet self moves upwards under the attraction of the magnetic force to drive 2 copper contacts (the copper contacts are not contacted and have enough movable gaps up and down) between the iron piece and the rubidium magnet to move upwards together, and the 2 copper contacts which are not contacted with each other are tightly pressed at the bottom (diameter is 7 mm) of the iron piece by the rubidium magnet under the attraction of strong magnetic force, and 2 copper contacts which are not contacted with each other in an open state are connected through the good electric conductivity of the iron piece; if the iron piece is fully wrapped by insulating plastic, 2 copper contacts cannot form an electric path, and the detection circuit is interrupted and cannot form a loop; if the iron part leaks, the strong magnet has no action response, the copper contact keeps the open state, and the detection circuit is interrupted and cannot form a loop.

Each iron piece (6 grains) at the bottom of the product is respectively adsorbed by magnetic force below to be connected with each contact, and the self-checking circuit triggers a green indicator lamp through a serial passage formed by the 6 grains of contacts; if any one or more iron pieces cannot form a connection point due to abnormal detection, the serial connection passage cannot be smoothly conducted, red flashing and buzzing of the alarm lamp can be continuously stopped, and a printing station person is reminded to check the state of the iron piece at the bottom of a product causing an alarm;

as shown in fig. 4, after the self-locking switch is pressed to start the circuit, the white indicator lamp is always on after the sensor detects that the product is in place, and meanwhile, the buzzer alarm lamp flashes red and sounds for about 0.5 seconds (namely, the white lamp is always on when the product is well placed, the alarm lamp flashes red and sounds), the circuit of the alarm can be immediately cut off to eliminate the alarm when the product passes through the detection of the iron piece, and the green indicator lamp is synchronously started; if the iron part detection fails, the alarm will continuously sound until the personnel manually takes away the product and leaves the sensor sensing distance, the sound of the alarm lamp will not flash.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments.
