Material inspection device for assembly line and detection method thereof

Abstract

The invention discloses a material detection device for an assembly line and a detection method thereof, comprising a first controller (8), a material detection device (2) and an image recognition detection device (9), the material detection device (2) is located at the conveying Between the guide rails, the lens area of ​​the camera in the image recognition detection device (9) covers the material inspection device (2); The first controller (8) is electrically connected, and the outer peripheral wall of the rotating drum (11) is provided with a plurality of groove bars (13) uniformly distributed along the circumferential direction and axially penetrating through the rotating drum (11). Its detection method is: image collection, judging whether there is a defect in the breach and classifying it, judging whether there is a length defect and classifying it, judging whether there is a reverse orientation and classifying it. After adopting this structure and method, the workpiece can be continuously photographed, and different workpiece defects can be classified to improve production efficiency.

Description

technical field [0001] The invention relates to the field of machine tool auxiliary equipment, in particular to a material picking device for an assembly line and a testing method thereof. Background technique [0002] At present, in actual production, in order to improve production efficiency, many production enterprises usually set up auxiliary equipment on the machine tool, such as feeding device, picking device, etc., which are especially suitable for assembly line production. In the prior art, the feeding device for some rods and rods is usually a device using a vibrating plate, that is, the vibrating plate is set at the feeding place, and after the workpiece to be processed is poured into the vibrating plate, the workpiece is shaken by the principle of vibration. One by one is output from the track inside the vibrating plate, and then sent to the predetermined position through the conveying guide rail outside the vibrating plate, and then the workpiece is sent to the s...

AI Technical Summary

Problems solved by technology

[0003] 1) Due to the large number of workpieces in the vibrating plate, especially small workpieces, the operator must use his eyes for a long time on the continuous production line, which causes visual fatigue. Therefore: on the one hand, it causes uncertainty in the quality of picking On the other hand, it also caused the high-intensity work of the operators, which affected the health; on the other hand, the production efficiency was extremely low, and the normal operation of the assembly line could not be guaranteed;

[0004] 2) What the human eye sees is only the appearance of the workpiece, and for some workpieces that look symmetrical in appearance but asymmetric in their internal structure, such as one end with chamfer and the other end without chamfer, the subsequent processing must be in When the inner chamfer is processed at one end, at this time, the workpiece must be moved in a certain direction. Therefore, the human eye cannot judge whether the position of the workpiece is correct, resulting in unqualified scrap parts being processed on the production line. On the one hand, it increases Production costs, on the other hand, reduce production efficiency;

[0005] 3) In addition, the workpieces that have been removed after inspection are also randomly removed from the track, and after a period of accumulation, they are put back into the vibrating plate for another vibration feeding. Therefore, with the work of the vibrating plate, these are removed twice The orientation of the vibrating-feed workpiece is still not necessarily correct, and another manual picking operation has to be performed, which reduces the efficiency of picking

[0008] 1) Since the workpiece is transported to the screening device, the workpiece is photographed and a template is selected, and the selected template is matched and screened, so its efficiency is very low;

[0009] 2) There are various problems in the workpiece, such as the orientation of the feed material, the length of the workpiece does not meet the requirements, and the workpiece itself has defects, etc., and the above-mentioned device is only equipped with a reversing device for the orientation of the workpiece. Unqualified products have been eliminated. Therefore, these rejected incomplete products also need to be classified manually, which also causes low work efficiency to a certain extent;

[0010] 3) In addition, the above-mentioned device includes many sensors, such as sensor I, sensor II and sensor III, as well as square sensor I and square sensor II, angle sensing sheet, etc. Therefore, on the one hand, the use of these sensors The cost of the device itself has been greatly increased; on the other hand, the use of these electronic components has increased the failure rate during use.
