Description
[technical field]
The utility model relates to a kind of pick-up unit, and in particular to a kind of pick-up unit of magnet poles direction.
[background technology]
At present, most of notebook computer automatically cuts out liquid crystal display or computer and enters dormant state and control mainly through a magnetic switch when upper cover closes.Generally on the plastic frame of liquid crystal display, assemble a magnet, on notebook mainboard, relevant position arranges a magnetic switch, when upper cover closes, this magnet is close to this magnetic switch, this magnetic switch detects the magnetic field of this magnet and action, thus send a control signal, make liquid crystal display closedown or computer enter dormant state.If the pole orientation of this magnet is anti-loaded, then this magnetic switch then because of cannot detect respective direction magnetic field and cannot action, thus liquid crystal display cannot be closed or make computer enter dormant state.
In notebook computer upper cover, assemble magnet mainly first puts magnet on the predeterminated position of this notebook computer upper cover according to default pole orientation, is then fixed on this notebook computer upper cover by this magnet hot melt by hot melting fixture.In prior art, detected by special messenger and check that whether this magnet is anti-loaded, namely hold the magnet of a detection magnet close to this notebook computer upper cover, judged that by the principle of " two like magnetic poles repel each other, there is a natural attraction between the sexes " whether the pole orientation of the magnet of hot melt assembling is correct.The mode of this employing manual detection, easy error in judgement, and efficiency comparison is low.
In view of this, the pick-up unit developing a kind of magnet poles direction is necessary, to solve the problem in fact.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of pick-up unit of magnet poles direction, and the pick-up unit in this magnet poles direction accurately can not only judge that whether magnet is anti-loaded, and improves work efficiency.
In order to achieve the above object, the pick-up unit in magnet poles direction of the present utility model, whether it is anti-loaded for the pole orientation detecting the default magnet in plastic parts, and the pick-up unit in described magnet poles direction comprises:
Power supply, it has positive pole and negative pole, described minus earth;
Conducting magnetic iron, its correspondence is located at the below of described default magnet;
Two conducting probes, its one end contacts described conducting magnetic iron respectively, and the other end of one of them conducting probe is electrically connected the positive pole of described power supply;
Relay, it has coil and two contacts, and described coil one end connects the other end of another conducting probe, and the other end of described coil is electrically connected the negative pole of described power supply, and a described contact connects the positive pole of described power supply;
Alarm, its one end is electrically connected another contact, and the other end is electrically connected the negative pole of power supply.
Preferably, described conducting probe is copper probe.
Preferably, two contacts of described coil are normally closed contact.
Preferably, described alarm is hummer or light emitting diode.
Compared to prior art, the pick-up unit in magnet poles direction of the present utility model, by the default magnet poles two like magnetic poles repel each other in employing conducting magnetic iron and plastic parts, there is a natural attraction between the sexes, make relay work or do not work, thus two of pilot relay contacts disconnect or close, make alarm equipment alarm, accurately can not only judge that whether default magnet is anti-loaded, and improve work efficiency.
[accompanying drawing explanation]
Fig. 1 illustrates the schematic diagram of pick-up unit one preferred embodiment one duty in the utility model magnet poles direction.
Fig. 2 illustrates the schematic diagram of another duty of pick-up unit one preferred embodiment in the utility model magnet poles direction.
[embodiment]
Refer to shown in Fig. 1 and Fig. 2, it depicts the schematic diagram of the schematic diagram of pick-up unit one preferred embodiment one duty in the utility model magnet poles direction and another duty of pick-up unit one preferred embodiment in the utility model magnet poles direction respectively.
The pick-up unit in magnet poles direction of the present utility model, whether it anti-loaded for the pole orientation detecting the default magnet 20 in plastic parts 10, in the present embodiment, the point-device direction of described default magnet 20 magnetic be N pole down, upward, the pick-up unit in described magnet poles direction comprises in S pole:
Power supply 30, it has positive pole 31 and negative pole 32, described negative pole 32 ground connection;
Conducting magnetic iron 40, its correspondence is located at the below of described default magnet 20, and the N of described conducting magnetic iron 40 extremely surpasses, and S pole is down;
Two conducting probes 50, its one end contacts described conducting magnetic iron 40 respectively, and the other end of one of them conducting probe 50 is electrically connected the positive pole 31 of power supply 30, is copper probe in two conducting probes 50 described in the present embodiment;
Relay 60, it has coil 61 and two contacts 62, described coil 61 one end connects the other end of another conducting probe 50, the other end of described coil 61 is electrically connected the negative pole 32 of described power supply 30, a described contact 62 connects the positive pole 31 of described power supply 30, and wherein said two contacts 62 are normally closed contact;
Alarm 70, its one end is electrically connected another contact 62, and the other end is electrically connected the negative pole 32 of power supply 30, and described alarm 70 is hummer or light emitting diode.
Refer to shown in Fig. 1, in the present embodiment, if presetting magnet 20 pole orientation installs correct, namely N pole down, and S pole upward, the then magnetic pole two like magnetic poles repel each other of conducting magnetic iron 40 and default magnet 20, conducting probe 50 and conducting magnetic iron 40 do not depart from, and by electric current in described conducting probe 50, described relay 60 coil 61 is energized, described two contacts 62 are off state, then alarm 70 is not reported to the police.
