Abstract
The utility model provides a magnet polarity testing arrangement which is used for testing magnets in different positions of one product and then determining whether the magnet polarity in the different positions of the product is correct or not. The magnet polarity testing arrangement includes a power line which is connected with an external power supply, a testing substrate which is connected with the power line, and at least one Hall IC which is disposed on the testing substrate and is connected to the external power supply through the power line. When one magnet on the product comes close to one Hall IC, the Hall IC displays the polarity by lighting a lamp according to the polarity of the magnet. The magnet polarity testing arrangement has the advantages of high testing efficiency, good testing results and the like, and can help to effectively reduce manpower cost.
Description
Technical field
The utility model relates to a kind of proving installation, especially relates to a kind of device for testing polarity of magnet.
Background technology
The part that on magnet, magnetic is the strongest is magnetic pole.There is magnetic field around in magnet, the interaction between magnet is exactly vehicular with magnetic field.Any little two magnetic poles that all have of magnet, the magnet that can freely rotate in surface level, when static, always magnetic pole points to south, another magnetic pole points to the north, energized south be called the South Pole, energized north be called the arctic.
In existing industrial products, conventionally on a product, use different magnetics to carry out arranged evenly, and the magnetic pole that distributes, thereby reach certain technique effect.But, in the said goods, easily cause the appearance of defective products due to pole arrangement mistake.Therefore need the magnet on product to carry out polarity test, whether correct with the magnet polarity arrangement of testing product, whether be the object of non-defective unit thereby reach test products.
But in proving installation and the method for testing of prior art, what mainly take is manual testing's mode, this test mode not only efficiency is lower, and easily causes the error of test result, the deficiency of the more high aspect of cost.
Utility model content
In view of above-mentioned deficiency of the prior art.The purpose of this utility model is to provide that a kind of testing efficiency is high, good test effect, can effectively reduce the device for testing polarity of magnet of human cost.
For realizing above-mentioned purpose of the present utility model, the utility model provides a kind of device for testing polarity of magnet, for the magnet of diverse location on a product test also so that the magnet polarity of the diverse location of definite product whether correct, described device for testing polarity of magnet comprises: a power lead, is connected to external power source; One test base, is connected to described power lead; Hall IC, described Hall IC is arranged on described test base, and is connected to described external power source by described power lead; Described Hall IC is at least more than one; Magnet on described product is during near described Hall IC, and described Hall IC shows polarity according to magnet polarity bright light.
According to above-mentioned design of the present utility model, described Hall IC is multiple, and described multiple Hall IC equidistantly or are not equidistantly arranged on described test base.
According to above-mentioned design of the present utility model, described Hall IC is multiple, described multiple Hall IC Heterogeneous Permutation on described test base.
Advantage of the present utility model and beneficial effect are: have that testing efficiency is high, good test effect, can effectively reduce the advantages such as human cost.
Brief description of the drawings
Fig. 1 is the perspective view of a kind of device for testing polarity of magnet the first embodiment of the present utility model;
Fig. 2 is the perspective view of a kind of device for testing polarity of magnet the second embodiment of the present utility model;

Embodiment
In order to further illustrate principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated, but described embodiment is only for furnishing an explanation and the use of explaining, can not be used for limiting scope of patent protection of the present utility model.
As shown in Figure 1, Figure 2 and Figure 3 be a kind of device for testing polarity of magnet of the present utility model, for the magnet 101 of diverse location on a product 10 test also so that magnet 101 polarity of the diverse location of definite product 10 whether correct, described device for testing polarity of magnet comprises: a power lead 1, is connected to external power source (not shown); One test base 2, is connected to described power lead 1; Hall IC 3, described Hall IC 3 is arranged on described test base 2, and is connected to described external power source (not shown) by described power lead 1; Described Hall IC 3 is at least more than one; Magnet 101 on described product 10 is during near described Hall IC 3, and described Hall IC 3 shows polarity according to the polarity bright light of magnet 101.
According to above-mentioned design of the present utility model, described Hall IC 3 is multiple, and described multiple Hall IC 3 equidistantly or are not equidistantly arranged on described test base 2.
According to above-mentioned design of the present utility model, described Hall IC 3 is multiple, described multiple Hall IC 3 Heterogeneous Permutation on described test base 2.
Advantage of the present utility model and beneficial effect are: have that testing efficiency is high, good test effect, can effectively reduce the advantages such as human cost.
Principle of work of the present utility model is: quantity and position that described Hall IC 3 is set according to the position correspondence of the magnet of product 10 101 on test base 2, after described proving installation energising, once the magnet 101 on described product 10 is near the Hall IC 3 on described test base 2,3 of described Hall IC are according to the polarity of the magnet 101 on described product 10 and bright light, as N incandescent red light, the blue lamp of S incandescent, vice versa.Thereby reach the object of the polarity of the magnet 101 on testing product 10.
Foregoing is only preferred embodiment of the present utility model and the variant that exemplifies; be not used for limiting the utility model; every within spirit of the present utility model and principle; any amendment and the improvement that need not creative thinking done, within all should being included in protection domain of the present utility model.
