Background technology
The sensitivity of magnetic reed switch (Reed switch) is an important parameter of magnetic reed switch, and the magnetic field intensity of magnetic reed switch junction closure is instigated in said sensitivity, or the number of ampere turns of outer magnetizing coil.Select magnetic reed switch that three key elements are arranged, the one, the current capacity of contact, the 2nd, overall dimension, the 3rd, sensitivity, the sensitivity of wherein measuring magnetic reed switch will relate to the measurement of magnetic reed switch AT value usually, said AT value refers to the number of ampere turns of outer magnetizing coil, is the product of electric current and the outer magnetizing coil number of turn when making magnetic reed switch adhesive or release condition.At present, magnetic reed switch need be reset to its AT value after producing, because magnetic reed switch belongs to fragile article, when traditional magnetic reed switch carries out the sensitivity replacement, be magnetic reed switch one by one to be dropped in the sensitivity replacement equipment successively by artificial method, this operation labour intensity is big, poor stability.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is the automatic replacement equipment that proposes a kind of magnetic reed switch sensitivity.
The purpose of this utility model will be achieved by the following technical programs:
A kind of automatic replacement equipment of magnetic reed switch sensitivity comprises heater, also comprises: a magnet chamber, and horizontal direction is provided with a pair ofly with the relative permanent magnet of opposite pole in the described magnet chamber, is used to make magnetic reed switch to be horizontal; Vertical first slideway of one front opening is arranged with the main induction coil on described first slideway; The end of described first slideway is connected with heater; The outlet of described heater is connected with the AT test machine by vertical second slideway, is arranged with secondary induction coil on described second slideway; Described AT test machine is connected with system respectively with heater; Be connected by vertical the 3rd slideway between the outlet of described AT test machine and the casing; The rocking arm absorption magnetic reed switch wherein of vacuum suction tube is with by one in described magnet chamber, and sends into the openend of described first slideway.
Further, above-mentioned automatic replacement equipment, wherein: be provided with block in the middle of described first slideway and the heater, described block is connected with cylinder.
The utility model realizes that by using the rocking arm of band vacuum suction tube the integral body when magnetic reed switch sensitivity is reset is thrown in; Movably block is housed in first slideway and the heater, can guarantees to have only a magnetic reed switch to enter heater at every turn; The magnetic reed switch AT value that measures is transferred to system, system analyzes according to the AT value, sending signal then adjusts the replacement temperature of heater, the sensitivity AT value of magnetic reed switch can be kept within the specific limits, automatization level and operating efficiency have been improved, simple in structure, easy to operate.
Following constipation closes the embodiment accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below by specific embodiment the utility model is described, but the utility model is not limited thereto.
The automatic replacement equipment of a kind of magnetic reed switch sensitivity of present embodiment as shown in Figure 1, comprises heater 1, one magnet chamber 2, and described magnet chamber 2 interior horizontal directions are provided with a pair of with the relative permanent magnet of opposite pole, are used to make magnetic reed switch 3 to be horizontal; Vertical first slideway 4 of one front opening is arranged with main induction coil 5 on described first slideway 4; The end of described first slideway 4 is connected with heater 1; Be provided with block 13 in the middle of described first slideway 4 and the heater 1, described block 13 is connected with cylinder 14.The outlet of described heater 1 is connected with AT test machine 7 by vertical second slideway 6, is arranged with secondary induction coil 8 on described second slideway 6; Described AT test machine 7 is connected with system 9 respectively with heater 1; Be connected by vertical the 3rd slideway 11 between the outlet of described AT test machine 7 and the casing 10; The rocking arm 12 absorptions magnetic reed switch 3 wherein of vacuum suction tube is with by one in described magnet chamber 2, and sends into the openend of described first slideway 4.
The application of present embodiment may further comprise the steps:
1, magnetic reed switch 3 is placed in the magnet chamber 2,, magnetic reed switch 3 is horizontal all the time because horizontal directions are provided with a pair ofly with the relative permanent magnet of opposite pole in the described magnet chamber 2;
2, the rocking arm 12 of band vacuum suction tube is drawn magnetic reed switch 3 from magnet chamber 2;
3, rocking arm 12 is decontroled magnetic reed switch 3, and it is dropped into the openend of first slideway 4, regains rocking arm 12, prepares to draw next magnetic reed switch 3;
4, magnetic reed switch 3 enters first slideway 4, to 5 energisings of main induction coil, makes magnetic reed switch 3 keep vertical position;
