第一次检测完成后，第一驱动件17驱动检测块16远离第一标准块14，并关闭检测电路20的开关22。对于第一次检测初定合格的工件，再进行第二次长度检测，具体为：第二驱动件18驱动第二标准块15朝向第一标准块14运动，且第一驱动件17驱动检测块16朝向第一标准块14运动，再次开启检测电路20的开关22，若检测电路20未形成闭合的回路，即表示工件的长度小于第二标准块15的第二长度L2，工件的长度最终确定合格。若检测电路20形成了闭合的回路，即表示工件的长度大于或等于第二标准块15的第二长度L2，工件的长度不合格。After the first detection is completed, the first driving member 17 drives the detecting block 16 away from the first standard block 14 and turns off the switch 22 of the detecting circuit 20. For the first inspection of the initially qualified workpiece, a second length detection is performed, specifically: the second driving member 18 drives the second standard block 15 to move toward the first standard block 14, and the first driving member 17 drives the detecting block. 16 moves toward the first standard block 14, and turns on the switch 22 of the detecting circuit 20 again. If the detecting circuit 20 does not form a closed loop, it means that the length of the workpiece is smaller than the second length L2 of the second standard block 15, and the length of the workpiece is finally determined. qualified. If the detecting circuit 20 forms a closed loop, that is, the length of the workpiece is greater than or equal to the second length L2 of the second standard block 15, the length of the workpiece is unacceptable.
可以理解，检测步骤不限于此，只要能检测工件的长度是否在第一长度L1与第二长度L2之间即可。It can be understood that the detecting step is not limited thereto as long as it can detect whether the length of the workpiece is between the first length L1 and the second length L2.
可以理解，在其他实施方式中，开关22和指示灯23也可替代为其他控制装置。可以理解，检测电路20也可取消，只要能够检测定位块13、工件、检测块16之间是否导电即可。It will be appreciated that in other embodiments, the switch 22 and indicator light 23 may be substituted for other control devices. It can be understood that the detecting circuit 20 can also be eliminated as long as it can detect whether the positioning block 13, the workpiece, and the detecting block 16 are electrically conductive.
上述工件长度检测装置100包括底板11、定位块13、第一标准块14、第二标准块15、检测块16、第一驱动件17及第二驱动件18。第一标准块14、第二标准块15分别具有第一长度L1和第二长度L2，定位块13与检测块16均导电，第一标准块14与第二标准块15均绝缘。当工件放置于第一标准块14、第二标准块15之间时，通过检测定位块13、工件、检测块16之间是否导电，即可判定工件的长度是否在第一长度L1与第二长度L2之间。上述工件长度检测装置100能够自动检测工件的长度是否合格，检测误差
小且效率较高，并且降低了人力成本。The workpiece length detecting device 100 includes a bottom plate 11, a positioning block 13, a first standard block 14, a second standard block 15, a detecting block 16, a first driving member 17, and a second driving member 18. The first standard block 14 and the second standard block 15 respectively have a first length L1 and a second length L2. The positioning block 13 and the detecting block 16 are both electrically conductive, and the first standard block 14 and the second standard block 15 are both insulated. When the workpiece is placed between the first standard block 14 and the second standard block 15, it can be determined whether the length of the workpiece is at the first length L1 and the second by detecting whether the positioning block 13, the workpiece, and the detecting block 16 are electrically conductive. Between length L2. The workpiece length detecting device 100 can automatically detect whether the length of the workpiece is qualified or not, and the detection error
Small and efficient, and reducing labor costs.
