The invention discloses a detection device and method for a LED
chip and a device. The device comprises a blue film or a device substrate clamping jig, an
annular array testing
electrode, and a power supply and electrical parameter acquisition
system. The
annular array testing
electrode is roller-shaped in appearance and provided with multiple groups of positive and negative test probes. When detection is carried out, the detection device is driven through a synchronous
pulley to enable the positive and negative test probes to be exactly contacted with a positive
electrode and a negative electrode of an LED
chip to be tested or exactly contacted with a positive electrode and a negative electrode of a device, sweep currents are connected into a
list of probes contacted with a substrate right now through a power supply in sequence, electrical parameters of the device are collected at the same time, and the synchronous
pulley drives the device to roll to the next adjacent
list of probes after collection is completed, and the next
list of LED chips or devices are tested. The technical method is extremely high in efficiency, detection efficiency can be improved by 6-10 times compared with a traditional detection method, the detection device is applied to the LED industry, detection efficiency of LED products is greatly improved, equipment loss is reduced, product cost competitive advantages are promoted, and the detection device has good industrialization application prospects.
