【摘要】：PCB板鉆頭是由超細(xì)硬質(zhì)合金棒材加工出來(lái)的,而超細(xì)硬質(zhì)合金棒材在無(wú)心磨削加工過(guò)程中常會(huì)產(chǎn)生崩角、磨面等缺陷。針對(duì)目前硬質(zhì)合金棒材缺陷人工檢測(cè)效率低、誤檢率高的問(wèn)題,采用電渦流無(wú)損檢測(cè)方法,開(kāi)發(fā)了一套硬質(zhì)合金棒材缺陷檢測(cè)系統(tǒng),以單片機(jī)為控制核心,設(shè)計(jì)了數(shù)據(jù)采集、A/D轉(zhuǎn)換、通訊、執(zhí)行機(jī)構(gòu)等電路,開(kāi)發(fā)了相應(yīng)的控制軟件。通過(guò)實(shí)驗(yàn)研究了檢測(cè)系統(tǒng)的提離效應(yīng)和邊界效應(yīng),實(shí)驗(yàn)結(jié)果表明研發(fā)的硬質(zhì)合金棒材缺陷檢測(cè)系統(tǒng)能有效分選出有缺陷的棒材,可以有效提高檢測(cè)準(zhǔn)確率和檢測(cè)效率。
[Abstract]:The PCB plate bit is manufactured from the ultra-fine cemented carbide bar, and the defects such as caving angle and grinding surface are often produced in the centerless grinding process of the ultra-fine cemented carbide bar. Aiming at the problems of low efficiency and high error detection rate of carbide bar defects at present, a set of defect detection system of cemented carbide bar is developed by using eddy current nondestructive testing method, with single chip microcomputer as the control core. The A / D conversion, communication and actuator circuits of data acquisition system are designed, and the corresponding control software is developed. The lifting effect and the boundary effect of the testing system are studied experimentally. The experimental results show that the developed system can effectively separate out the defective bars, and can effectively improve the detection accuracy and efficiency.
