Brake block appearance defect multi-station online detection device and method

Abstract

The invention discloses a brake block appearance defect multi-station online detection device and method. A direct current motor and a speed regulator are connected with a conveying belt for operation; a support frame is arranged on a base; three stations are sequentially arranged on the conveying belt along the conveying direction; a backlight light source module, an annular light source module and a coaxial light source module are sequentially arranged at the positions of the three stations; an industrial camera module is arranged right above the three stations; pneumatic push rods are arranged on the side edge of the upper belt surface of the conveying belt at the positions of the three stations; a photoelectric switch is arranged on the top of each pneumatic push rod; each pneumatic push rod is connected with an air compressor through an electromagnetic valve; the other side edge of the upper belt surface of the conveying belt is provided with a defective product material collecting box. A complete brake block surface defect automatic detection flow line is formed; different kinds of defects on the surface of a brake block can be detected through the arrangement of different light sources; the real-time on-line detection is realized; the multi-station detection integration is realized; the equipment cost and the labor cost are reduced; the work efficiency is improved.

Description

technical field [0001] The invention relates to an online detection device and method, and relates to a multi-station online detection device and method for appearance defects of brake pads, which uses machine vision technology to detect appearance defects of brake pads. Background technique [0002] Brake pad is a common name for brake lining, which is the friction material that contacts the brake drum (disc). When the driver has a braking behavior, the brake pads are under pressure and generate friction with the brake drum (disc), so as to achieve the purpose of vehicle deceleration. Brake pads are an important safety part of the vehicle braking system, and their quality directly affects the braking performance of the vehicle, and is related to the safety of life and property of the vehicle drivers and passengers. [0003] In the industrial production line, in order to meet the two-way requirements of production speed and product quality, it is necessary to cooperate with...

AI Technical Summary

Problems solved by technology

Due to factors such as visual fatigue and emotional fluctuations of quality inspection workers, the traditional method has poor quality standards, slow detection speed, and low efficiency. At the same time, for brake pads, which have many inspection items, traditional machine vision inspection can only detect a certain type of defect, while the multi-station inspection system has high equipment cost and low efficiency. Therefore, in the production of brake pads The industry urgently needs a multi-station appearance defect online detection device
