Abstract:
An electronic welding seam gauge comprises a reference positioning block and an electronic displacement measuring member. The reference positioning block has a contacting surface that abuts against a first abutting surface to form a first reference point, and the electronic displacement measuring member is disposed at a side of the reference positioning block, having a displacement probe and a displaying portion, wherein a displacement that the displacement probe moves to abut against a second reference point of a second abutting surface with respect to the first reference point is displayed by the displaying portion for providing a more precise measurement with respect to the welding seam, so as to enable the welded product to comply with the standards.
Abstract:
Disclosed is a method for automatically sorting LEDs (light emitting diode) according to electrostatic resistance and a system using the same. The system includes a transport carrier for laying LEDs and passing LEDs through an electrostatic discharging zone, a lightening evaluating zone, and a sorting zone in sequence. An electrostatic discharging device discharges an electrostatic power to the LED in the electrostatic discharging zone. Furthermore, a lighting device inputs a lightening power to the LED in the lightening evaluating zone. Moreover, an evaluating device in the evaluating zone generates an evaluating signal to a sorting device in the sorting zone according to the lighting condition of the LED for allowing the sorting device to sort LEDs according to electrostatic resistance. Thereby the reliability both for the failure rate and the detection rate can be raised.
