Self-adhesive iron core quality control equipment

Abstract

A self-adhesive iron core quality control device is suitable for inspecting a self-adhesive iron core being transported downstream on a conveyor belt. It includes a sensing unit for detecting whether the self-adhesive iron core has entered a temporary holding area of ​​the conveyor belt, a detection unit, and a quality judgment unit. The detection unit includes a positioning module, a measuring module having a first transducer for transmitting a pulse signal and a second transducer for receiving the pulse signal, and a server for calculating amplitude and time information generated by the pulse signal. The quality judgment unit compares the amplitude and time information with acceptable information to see if they are within an error range. Through the detection unit and the quality judgment unit, non-destructive testing of the self-adhesive iron core is achieved, and its quality is determined.

Claims

1. A self-adhesive iron core quality control device, suitable for detecting a self-adhesive iron core being conveyed on a conveyor belt to a downstream end, and comprising: a sensing unit suitable for detecting whether the self-adhesive iron core has entered a temporary holding area of ​​the conveyor belt; A detection unit, suitable for being disposed on one side of the conveyor belt and spaced apart from the sensing unit, includes a positioning module for fixing the self-adhesive core to or removing it from the temporary holding area, and a measuring module spaced apart from the positioning module. The measuring module has a first transducer for transmitting a pulse signal toward one of the top and bottom surfaces of the self-adhesive core, a second transducer for receiving the pulse signal, an ultrasonic flaw detector electrically connected to the first and second transducers, and a server connected to the ultrasonic flaw detector for calculating amplitude information and time information generated by the pulse signal; and a quality judgment unit connected to the detection unit for comparing the amplitude information and the time information with a qualified information defined as a standard value to see if they are within an error range.

2. The self-adhesive core quality control equipment as described in claim 1, wherein, The sensing unit includes two mutually symmetrical push rod mechanisms that approach the conveyor belt and abut against the left and right sides of the self-adhesive core, and a sensing module disposed at the opposite downstream end of the push rod mechanisms.
