Embodiment Construction

[0034] In the following, the concept, specific structure and technical effects of the present invention will be further described in conjunction with the accompanying drawings to fully understand the purpose, features and effects of the present invention.

[0035] In the rivet machine vision automatic detection system of the present invention, the rivets to be tested can be stacked in the storage bin in batches, the rivets in the storage bin fall into the vibrating tray at a uniform speed, and the output port of the rivet track of the vibrating tray is connected with the upper end of the linear track , The rivets are placed in the tooth openings on the mechanical turntable in an orderly manner via a linear track, and the operation of the vibrating tray and the stepping motor are controlled by the PLC and sensors at various positions. When the rivet passes through the detection positions of the two cameras, the photos are taken, and the photos are transmitted to the industrial comp...

Abstract

The invention discloses a machine vision automatic detection system for rivets. The machine vision automatic detection system for rivets comprises a PLC (programmable logic controller), two industrial cameras, a storage bin, a vibration feed plate, a linear rail, a mechanical rotary plate, a waste product blowing pipe, a waste product discharging trough, a salable product blowing pipe, a salable product discharging trough, discharging baffles, an image acquisition card, an industrial personal computer, a touch screen, an electromagnet, a pneumatic electromagnetic valve, an upper sensor, a lower sensor, a hole sensor, a count sensor, a stepping motor drive and a stepping motor. The detection precision of the machine vision automatic detection system for rivets is within +/-0.03mm, and the electromagnetic valve is controlled by the PLC to complete precise waste product blowing and realize separation of salable products from waste products. The final number of the salable products is accurately recorded by a counter, and a discharging port is closed according to time difference to prepare for a subsequent packaging procedure. In addition, all data are recorded in a database, and various production, client, analysis and CPK (complex processing capability index) report forms can be generated by one key.

Description

Technical field [0001] The present invention relates to the technical field of industrial automation detection, in particular, to a rivet machine vision automatic detection system, which is used to identify the shape, specification, and size of different rivets, and complete the work of separating positive waste products. Background technique [0002] Modern industrial automation production includes almost all industries such as automobile manufacturing, pharmaceuticals, electronics, packaging, printing, daily chemicals, building materials, currency, card manufacturing, etc., which involves a variety of part specification inspections and size recognition, such as batches of auto parts Processing, rivet, screw size inspection, IC specification recognition, etc. Usually this kind of highly repetitive and intelligent work can only be done with human eyes. However, in some cases, it is impossible for people to perform continuous and stable measurement with the naked eye, such as pre...
