I. Quick Answer<\/span><\/h3>\n

Yes<\/span><\/strong>, modern assembly machines c<\/a>an detect defective products\u00a0<\/span>during the assembly process<\/span><\/strong>\u00a0e\u00a0<\/span>automatically reject them<\/span><\/strong>\u00a0without stopping the production line. This is a standard feature in advanced automated assembly systems.<\/span><\/p>\n

\n

II. How It Works<\/span><\/h3>\n
\n\n\n\n\n\n\n\n\n\n\n
Step<\/span><\/th>\nAction<\/span><\/th>\n<\/tr>\n<\/thead>\n
1<\/span><\/td>\nParts are fed into the assembly machine (e.g., via a vibratory bowl feeder).<\/span><\/td>\n<\/tr>\n
2<\/span><\/td>\nInspection stations<\/span><\/strong>\u00a0are placed at key points in the assembly sequence (e.g., after part insertion, after fastening, after final assembly).<\/span><\/td>\n<\/tr>\n
3<\/span><\/td>\nSensors or vision systems<\/span><\/strong>\u00a0check each product for defects.<\/span><\/td>\n<\/tr>\n
4<\/span><\/td>\nIf a product passes inspection, it continues to the next station.<\/span><\/td>\n<\/tr>\n
5<\/span><\/td>\nIf a product fails inspection, the machine triggers a\u00a0<\/span>reject mechanism<\/span><\/strong>\u00a0(air blast, pusher, diverter) to remove the defective part from the line.<\/span><\/td>\n<\/tr>\n
6<\/span><\/td>\nThe defective part is collected in a\u00a0<\/span>reject bin<\/span><\/strong>\u00a0for later analysis or rework.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n

III. Common Defect Detection Methods<\/span><\/h3>\n
\n\n\n\n\n\n\n\n\n\n\n\n\n
Method<\/span><\/th>\nWhat It Detects<\/span><\/th>\nNotas<\/span><\/th>\n<\/tr>\n<\/thead>\n
Vision system<\/span><\/strong>\u00a0(camera + software)<\/span><\/td>\nMissing parts, incorrect orientation, surface defects, scratches, wrong color, misalignment, foreign objects<\/span><\/td>\nMost flexible method; can detect many types of defects in one station.<\/span><\/td>\n<\/tr>\n
Torque sensor<\/span><\/strong><\/td>\nInsufficient or excessive fastening torque (screws, bolts)<\/span><\/td>\nMonitors screwdriving or press\u2011fit operations.<\/span><\/td>\n<\/tr>\n
Force \/ pressure sensor<\/span><\/strong><\/td>\nInsufficient insertion force, missing components, press\u2011fit depth<\/span><\/td>\nDetects abnormal resistance during insertion.<\/span><\/td>\n<\/tr>\n
Presence sensor<\/span><\/strong>\u00a0(photoelectric, inductive, or fiber optic)<\/span><\/td>\nMissing components or parts<\/span><\/td>\nSimple and fast but limited to presence\/absence only.<\/span><\/td>\n<\/tr>\n
Leak tester<\/span><\/strong>\u00a0(pressure or vacuum)<\/span><\/td>\nLeaks in sealed or fluid\u2011containing products<\/span><\/td>\nUsed in automotive, medical, and pneumatic applications.<\/span><\/td>\n<\/tr>\n
Electrical test<\/span><\/strong><\/td>\nContinuity, resistance, short circuits<\/span><\/td>\nUsed for electronic or wired assemblies.<\/span><\/td>\n<\/tr>\n
Dimension gauge<\/span><\/strong>\u00a0(laser or mechanical)<\/span><\/td>\nOut\u2011of\u2011tolerance dimensions<\/span><\/td>\nVerifies critical dimensions (e.g., height, width, diameter).<\/span><\/td>\n<\/tr>\n
Weight check<\/span><\/strong>\u00a0(checkweigher)<\/span><\/td>\nMissing components or material<\/span><\/td>\nDetects missing screws, seals, or liquids.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n

IV. Rejection Mechanisms<\/span><\/h3>\n
\n\n\n\n\n\n\n\n\n\n
Mechanism<\/span><\/th>\nHow It Works<\/span><\/th>\nSuitable For<\/span><\/th>\n<\/tr>\n<\/thead>\n
Air blast nozzle<\/span><\/strong><\/td>\nBlows the defective product off the conveyor or track<\/span><\/td>\nSmall, lightweight parts<\/span><\/td>\n<\/tr>\n
Pusher \/ solenoid plunger<\/span><\/strong><\/td>\nPushes the product sideways into a reject chute<\/span><\/td>\nMost products; reliable and simple<\/span><\/td>\n<\/tr>\n
Diverter gate \/ flipper<\/span><\/strong><\/td>\nRedirects the product to a reject conveyor<\/span><\/td>\nProducts on conveyors; can handle heavier items<\/span><\/td>\n<\/tr>\n
Robotic pick\u2011and\u2011place reject<\/span><\/strong><\/td>\nRobot picks the defective item and places it into a reject bin<\/span><\/td>\nFlexible reject handling for many product types<\/span><\/td>\n<\/tr>\n
Drop\u2011out \/ trapdoor<\/span><\/strong><\/td>\nA trapdoor opens, allowing the part to fall into a reject bin<\/span><\/td>\nGravity\u2011fed systems; parts that can fall freely<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n

V. Reject Handling Workflow Example<\/span><\/h3>\n

VI. Important Considerations<\/span><\/h3>\n
\n\n\n\n\n\n\n\n\n\n\n
Factor<\/span><\/th>\nRecommendation<\/span><\/th>\n<\/tr>\n<\/thead>\n
Inspection position<\/span><\/strong><\/td>\nPlace inspection stations after each critical operation to catch defects early.<\/span><\/td>\n<\/tr>\n
Reject delay time<\/span><\/strong><\/td>\nProgram a small delay to allow the defective part to reach the reject mechanism.<\/span><\/td>\n<\/tr>\n
Data logging<\/span><\/strong><\/td>\nRecord reject count and defect type for quality analysis (helps identify recurring issues).<\/span><\/td>\n<\/tr>\n
Operator alert<\/span><\/strong><\/td>\nSound an alarm or show a message on the HMI when a high reject rate is detected.<\/span><\/td>\n<\/tr>\n
Reject bin<\/span><\/strong><\/td>\nProvide a clearly marked bin with separate compartments for different defect types.<\/span><\/td>\n<\/tr>\n
Rework loop<\/span><\/strong><\/td>\nFor some parts, include a manual rework station near the reject bin for minor defects.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
