Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-9, the present invention provides a technical solution: LED outward appearance detects, including interlock base 1, interlock base 1 top is fixed with vision A portion 2, vision B portion 3, vision C portion 4 and vision D portion 5 in proper order, vision A portion 2, vision B portion 3, vision C portion 4 and vision D portion 5 all install visual detection camera 6.
The vision A part 2 scans the front end of the LED product through a front end vision detection camera 6 and is used for detecting the problems of impurities, dirt, scars, eccentricity, bubbles and the like of the LED product.
Visual B portion 3 scans the LED product upper end through upper end visual detection camera 6 for inserted sheet, debris, black point, fish tail and bubble scheduling problem about detecting LED product support.
And the visual C part 4 scans the bottom end of the LED product through a bottom end visual detection camera 6 and is used for detecting the problems of more glue, less glue, deep insertion, shallow insertion and the like of the LED product.
The vision D part 5 scans the front end of the LED product through a front end vision detection camera 6 and is used for detecting the problems of wire arc and no welding wire of the LED product.
And the outer side of the vision A part 2 is sequentially provided with a cutting die station 7, a manipulator material taking station 8 and a driving disc feeding station 9.
And an NG station 10 and a leveling single-chip receiving station 11 are sequentially arranged outside the vision D part 5.
The whole machine adopts a vibrating disc feeding process, a vision scanning camera 6 adopts a Firefly series machine vision camera of FLIR system company, the machine vision camera is transversely pushed to a manipulator material taking station 8 by adopting an air cylinder, the air cylinder is preferably of SCA2 model, then a manipulator is driven by a servo motor to carry a support into a mould, the servo motor is preferably of 80ST-M02430 model, then the front end of an LED product is scanned by a vision detection camera 6 of a vision A part 2 through moving X, Y coordinates of a moving component, so that the problems of impurities, dirt, scars, eccentricity, bubbles and the like of the LED product are detected, the scanning result is shown in figure 3, then the front side of the LED product is scanned by a vision B part 3, the detection of the problems of left and right inserting pieces, impurities, black points, scratches, bubbles and the like of the support is completed, the scanning result is shown in figure 4, then the bottom surface of the LED product is scanned by a vision C part 4, to detect the problems of more glue, less glue, deep insertion and shallow insertion, etc., the scanning result is as shown in figure 5, and finally the front end is scanned by the vision D part 5 to complete the problems of bottom surface line arc and bonding wire, the scanning result is as shown in figure 6, then, based on the detected data of the vision A part 2, the vision B part 3, the vision C part 4 and the vision D part 5, judging the products and automatically eliminating defective products, and transporting the rest of the defective products to a finished product single-chip material receiving station by a manipulator for arranging and storing, the appearance detection of the LED product can be finished to distinguish the prior art, the traditional condition that workers hold the product under strong light is broken, or the traditional process of observing and detecting by naked eyes under a microscope can effectively relieve the burden of staff, and the eyesight of the eyes is effectively protected, so that the benefit and the safety performance can be effectively improved under the condition of quality.
