Description
Technical field
The present invention relates to the sorting equipment of buzzer, particularly to the mechanism for testing of electrode test part of a kind of buzzer and the method for automatic detecting electrode thereof.
Background technology
Buzzer has that volume is little, highly sensitive, little power consumption, good reliability, the feature such as cheap and have good frequency characteristic.Due to buzzer simple in construction, steady quality, cheap, so market application amount is very big, it is widely used in the electronic products such as computer, printer, photocopier, alarm, electronic toy, vehicle electronics, telephone set, intervalometer making microphone device.Buzzer certified products volume is more than 85 decibels, and in order to ensure the stable performance of buzzer, needs after buzzer is completed carrying out quality testing operation one by one, it is therefore an objective to filter out the buzzer not meeting quality standard.
Buzzer vibration just can be with sounding, and when we add DC source to buzzer, internal circuit can add, to coil, the electric current being continually changing automatically, allows magnetic field suction sound film constantly deform, thus can send sound.If the both positive and negative polarity wrong of buzzer during test, the sounding of buzzer can be the least, it is also possible to not sounding, even can burn out buzzer circuit.Therefore during detection, buzzer must be noted that correctly to connect pin, and can only be at present by manually rule of thumb judge pin longer be set to positive pole；Cannot separate both positive and negative polarity from length pin for having cut foot, also the low-voltage below self energy 3V is connected the resistance in 100 Europe, tries to contact buzzer pole foot, can represent that wiring is correct by sounding.And the mode not only inefficiency of this detection buzzer electrode, accuracy rate is the highest, is even easily damaged buzzer.
Summary of the invention
In order to overcome the artificial existence when test buzzer both positive and negative polarity: inefficiency, accuracy rate is the highest, is even easily damaged the deficiency of buzzer, and the present invention provides a kind of buzzer electrode test mechanism and the method for automatic detecting electrode thereof.
For realizing above-mentioned goal of the invention, the buzzer electrode test mechanism of the present invention have employed techniques below scheme:
According to an aspect of the present invention, a kind of buzzer electrode test mechanism provided, including two groups of four testing needles being arranged on test board, test board is connected fixing with driving means, in order to drive test board to move up and down, drive testing needle descending, until the two of one of which testing needles contact with two electrode pads on the buzzer line plate side on monitor station when test board moves downward.
In some embodiments, described driving means is lift cylinder.
Method based on above-mentioned buzzer electrode test mechanism's realization automatic detection buzzer electrode, it is characterised in that comprise the following steps:
A, buzzer enter monitor station and guarantee its stitch upward and in placing in tandem, on monitor station, buzzer is corresponding with buzzer electrode test mechanism；
B, driving means drive test board to move up and down, and drive testing needle descending, until the two of one of which testing needles contact with two electrode pads on the buzzer line plate side on monitor station when test board moves downward；
C, generation short circuit after two testing needles in one group of left side contact with two electrode pads on buzzer line plate, this signal is sent to PLC access point 1 by system, before this signal is identified as buzzer when the time comes, electrode foot is positive pole foot, and rear electrode foot is then identified as negative pole foot；Producing short circuit with two electrode pads on buzzer line plate after two testing needles in one group of right side contact, this signal is sent to PLC access point 2 by system, and before this signal is identified as buzzer when the time comes, electrode foot is negative pole foot, and rear electrode foot is identified as positive pole foot；Thus reach automatically to identify the purpose of buzzer both positive and negative polarity.
In some embodiments, described monitor station is index dial mechanism, this index dial mechanism includes the index dial being controlled by the drive unit start and stop, four recess stations are offered on this index dial, splicing sheet is separately mounted on recess station, and buzzer carries out detecting operation in pan feeding streamline enters splicing sheet.
Use above technical scheme, decrease artificial dependence at detection equipment buzzer, be greatly improved work efficiency, it determines both positive and negative polarity accuracy rate is high and buzzer will not be caused damage.Its qualification rate is made to be greatly improved.Its junction structure is simple, compact, reduces processing cost so that it is qualification rate is greatly improved and also reduces processing cost.
