Assembling magnet mainly is earlier magnet to be put on the predeterminated position of this notebook computer upper cover according to preset pole orientation in notebook computer upper cover, through the hot melt tool this magnet hot melt is fixed on this notebook computer upper cover then.In the prior art, detect through the special messenger and to check the whether neglected loading of this magnet, and hold one and detect the magnet of magnet, judge through the principle of " same sex is repelled each other, and there is a natural attraction between the sexes " whether the pole orientation of the magnet of hot melt assembling is correct near this notebook computer upper cover.The mode of this employing manual detection, not only cost of labor is higher, and when detecting the pole orientation mistake since this magnet hot melt be assembled on the notebook computer upper cover, product can't be done over again and scrapped, material unaccounted-for (MUF) is bigger.
Therefore, be necessary to develop a kind of device that can detect magnet neglected loading and pole orientation automatically in fact,, reduce manual detection cost and material unaccounted-for (MUF) to overcome the defective of prior art.
[utility model content]
In view of this; The purpose of the utility model is to provide the automatic detection device of a kind of magnet neglected loading and pole orientation; To overcome the defective of prior art, can before the assembling of magnet hot melt, in time detect the product of neglected loading magnet and pole orientation mistake, reduce manual detection cost and material unaccounted-for (MUF).
For achieving the above object; The utility model provides the automatic detection device of a kind of magnet neglected loading and pole orientation; In order to detect the preset magnet in the plastic parts, it is characterized in that, mainly comprise the testing circuit of forming by a power supply, an optoelectronic switch, a warning horn, an aluminum strip and a conducting block; Wherein this aluminum strip and this conducting block form a normally closed switch; One end of this aluminum strip rotatably is connected on this testing circuit, and its other end can this link be that the center touches on this conducting block with swinging up and down, the end that this aluminum strip can swing up and down to the magnetic pole that should preset magnet be provided with one with this magnetic pole and magnetic field detection magnet in the opposite direction; This optoelectronic switch is a normally open, and when being positioned over plastic parts this automatic detection device top, this optoelectronic switch receives reflection ray and the closure of plastic parts.
Preferably, this conducting block is a copper billet.
Compared to prior art, the automatic detection device of neglected loading of the utility model magnet and pole orientation can detect magnet neglected loading and the pole orientation setup error in the plastic parts automatically, has overcome the defective of prior art, has reduced manual detection cost and material unaccounted-for (MUF).

[embodiment]
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
See also Fig. 1 to Fig. 4; The utility model provides the automatic detection device of a kind of magnet neglected loading and pole orientation, in order to detect the preset magnet 11 in the notebook computer upper cover 10, in present embodiment; The upper end was the N utmost point in the time of should presetting magnet 11 correct installations, and the lower end is the S utmost point.The automatic detection device of neglected loading of the utility model magnet and pole orientation mainly comprises the testing circuit of being made up of a 24V power supply 20, an optoelectronic switch 30, a warning horn 40, an aluminum strip 50 and a copper billet 60; Wherein this aluminum strip 50 forms a normally closed switch with this copper billet 60; One end of this aluminum strip 50 rotatably is connected on this testing circuit; Thereby its other end can this link be the center to touch with swinging up and down and this testing circuit is broken off or is communicated with; The end that this aluminum strip 50 can swing up and down to the magnetic pole that should preset magnet 11 be provided with one with this magnetic pole and magnetic field detection magnet 51 in the opposite direction; The upper end of this detection magnet 51 is the N utmost point in present embodiment, and the lower end is the S utmost point; This optoelectronic switch 30 is a normally open, and when being positioned over notebook computer upper cover 10 this automatic detection device top, this optoelectronic switch 30 receives reflection ray and closure.
See also Fig. 1, it illustrates automatic detection device preferred embodiment first working state schematic representation of neglected loading of the utility model magnet and pole orientation.When the automatic detection device of neglected loading of the utility model magnet and pole orientation being installed on the pedestal of hot melt tool, before the hot melt assembling, notebook computer upper cover 10 is put on this automatic detection device; These optoelectronic switch 30 closures; This moment, the magnet 11 in the notebook computer upper cover 10 was correctly put, effect that there is a natural attraction between the sexes because the N utmost point of the detection magnet 51 of these aluminum strip 50 swinging ends receives the S utmost point of magnet 11, and these aluminum strip 50 swinging ends receive attractive force and the upwards swing of magnet 11; Separate with this copper billet 60; Testing circuit breaks off, and warning horn does not give the alarm, and operating personnel carry out the hot melt operation.
