Abstract
The invention discloses an automatic voltage detection device. A battery pack is placed on a detection base of the detection device, each group of battery is correspondingly provided with a diode, the detection base sinks to trigger an approach switch located at the bottom, the approach switch inputs a signal to a programmable logic controller (PLC), the PLC controls an air cylinder to abut a top probe to one end of the battery, the other end of the battery is in contact with a bottom probe to form a detection circuit, a resistor is added in the detection circuit, the obtained voltage value of a system is actual voltage value during data sampling, when the detected voltage difference exceeds a set range or the voltage of a single lithium battery is not in the set range, and the PLC drives the diode to give out light, so that an unqualified battery can be rapidly found out. The automatic voltage detection device has the advantages that the work efficiency is high, and the dropout voltage of the battery pack can be rapidly and accurately detected.
Description
Technical field
The present invention relates to a kind of automatic voltage detector, belong to lithium battery battery bag voltage detecting field.
Background technology
Lithium battery is widely used in the various electronic as a kind of high efficient energy sources carrier, such as imaging device, and optical instrument, communication apparatus, Medical Instruments, computing machine and mobile phone etc.
In battery PACK industry, after finishing, traditional lithium battery coding falls into the rewinding box by the travelling belt conveying, because lithium battery is the random rewinding box that falls into, can only rely on and manually put vanning in order, inefficiency easily produces between lithium battery when falling into simultaneously the rewinding box and collides with, and affects product quality.
In daily power brick voltage detecting, the normal operation multimeter detects the global voltage of battery, and perhaps substep repeated detection monomer battery voltage relies on and judges manually whether power brick voltage meets standard, there is inefficiency in this mode, judges the drawbacks such as inaccurate.
Summary of the invention
The present invention proposes a kind of automatic voltage detector, detect in order to realize automatic voltage, increase work efficiency, avoid manually-operated to affect product quality.
For realizing this purpose, the method applied in the present invention is: a kind of automatic voltage detector, comprise detecting device and PLC, and electric battery is placed on the detecting device, PLC control detecting device detects.
Described detecting device comprises detection base, top probe, bottom probe, cylinder and approach switch, and top probe and bottom probe are positioned at and detect the base two ends, and approach switch is arranged on and detects the base bottom, and cylinder connects top probe.
Described approach switch connects PLC, and PLC connects cylinder.
Described electric battery is connected with a diode.
Described PLC control linkage diode.
After touching the electric battery two ends, top probe and bottom probe form testing circuit.
Be provided with resistance in the described testing circuit.
The number of described top probe and bottom probe is for being 6, and top probe is identical with putting in order of bottom probe.
Its beneficial effect is: be loaded with resistance in testing circuit, make system guarantee that when data sampling the voltage volume that obtains is the virtual voltage volume, when the voltage difference that obtains when detection surpasses setting range or single-lithium-battery cell voltage not at setting range, PLC will drive led lighting, in order to the underproof battery of quick lock in, this pick-up unit high efficiency can detect the pressure reduction of power brick quickly and accurately.
