Electronic error-proofing identifying counter

Abstract

The invention discloses an electronic error-proofing identifying counter. The electronic error-proofing identifying counter comprises a test base and a test board, wherein a detection circuit is arranged in the test board; the detection circuit comprises a power supply part, a signal sampling part, a judging part, a counting part and a self-locking part, wherein a plurality of inductors are mounted on the test base; the inductors are connected with a signal receiving circuit in the detecting circuit; the position of at least one inductor is matched with a common feature point of a workpiece; the position of at least one inductor is matched with a distinguishing feature point of the workpiece; a counting part of the detecting circuit comprises a first counter and a second counter; the judging part comprises a NOT gate; the self-locking part comprises a third counter which is used for receiving a signal fed back by the judging circuit. The electronic error-proofing identifying counter has a workpiece identifying function and a counting function, and can be used for quickly and accurately checking whether the workpiece is correct or not; if the workpiece is a qualified workpiece, a green signal lamp is light, and a buzzer shortly rings to prompt; if a similar workpiece is found, the counter is automatically locked and only can continuously work after being unlocked through a key.

Description

technical field [0001] The invention relates to a production line automation equipment, in particular to an electronic error-proof identification counter for preventing confusion of similar products. Background technique [0002] Aluminum alloy die casting process is one of the most widely used processes in the production of auto parts. However, there are similar or partially similar aluminum alloy parts, but the models and specifications are completely different products. For example, the distinguishing feature points of some workpieces are only a groove, a hole or a boss, or even only the depth or width of the groove is different. When these workpieces with similar shapes pass through the quality inspection line and packaging line, they need to be inspected and distinguished by manual visual inspection. [0003] Repeated inspection for a long time will cause fatigue and inattention, which may cause products of different specifications to be mixed or packaged incorrectly....

If it is found that there are defective products with missing screws, it can only remind the operator to pay attention. It is still necessary to manually monitor the alarm of the buzzer to judge whether the screws are missing. If the workshop is noisy and the workers are careless, the defective products will still flow into the next process
