Abstract

The invention discloses a bearing part automatic sorting method. The bearing part automatic sorting method comprises the following steps: a conveying device conveys bearing parts to be detected to a detecting area; after the detected bearing parts are conveyed to the detecting area, a position detecting sensor is triggered to send position signals of the bearing parts to be detected to a visual detecting system in real time; the visual detecting system obtains images of the bearing parts to be detected according to position information of the bearing parts to be detected; the obtained images are compared with standard data of the bearing parts to judge if the bearing parts are qualified products; and then, the sorting is performed. The bearing part automatic sorting method detects the surface defects of the bearing parts by a visual mode, is clear in imaging, can guarantee the detecting accuracy, and meanwhile, adopts a belt conveying structure capable of continuously detecting to improve the detecting efficiency.

Example Embodiment

[0028] The present invention will be further explained below in conjunction with the drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those of ordinary skill in the art can realize that the described embodiments can be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature, and are not used to limit the protection scope of the claims.

[0029] Such as figure 1 As shown, according to the automatic sorting method for bearing parts according to an embodiment of the present invention, the automatic sorting method for bearing parts includes the following steps:

[0030] (1) Transport the bearing parts to be tested to the testing area through the conveyor;

[0031] (2) After the bearing component to be detected is transported to the detection area, the position detection sensor 3 is triggered and the position signal of the bearing component to be detected is transmitted to the visual detection system 4 in real time;

[0032] (3) The visual inspection system 4 acquires an image of the bearing component to be tested according to the position information of the bearing component to be tested, and compares the acquired image with the standard data of the bearing component;

[0033] (4) If the obtained image of the bearing component to be tested is compared with the standard data of the bearing component and it is a qualified product, the qualified product is transported to the qualified product hopper 6 by the conveying device;

[0034] (5) If the obtained image of the bearing component to be tested is compared with the standard data of the bearing component, it is a nonconforming product, the visual inspection system 4 transmits the nonconforming product information to the nonconforming product rejection mechanism 5. The unqualified product is transported by the conveying device to the unqualified product rejection mechanism 5, and the position detection sensor 3 detects the position signal of the unqualified product. At this time, the unqualified product rejection mechanism 5 works and rejects the unqualified product To the unqualified product funnel 7.

[0035] In the present invention, the processed surface defects of the bearing parts to be tested are detected in a visual manner, and the imaging is clear, which can effectively ensure the accuracy of the detection; at the same time, a continuous detection conveying device is used, and the bearing parts to be tested are While conveying on the conveying device, operations such as visual inspection, rejecting unqualified products, and putting qualified products into the basket can be completed, thereby improving the detection efficiency; the position detection sensor 3 of the present invention is used to detect the bearing position and send the position signal to the visual inspection The system 4 or the rejecting mechanism 5 for unqualified products, so that the visual inspection system 4 can obtain images at the right time, compare with the standard data of bearing parts, and reject the unqualified products from the conveying device in time.

[0036] Further, before the step (1), it also includes the following steps:

[0037] The bearing component to be tested is immersed in fluorescent liquid or coated with fluorescent powder.

[0038] In this way, when the bearing parts to be inspected after being soaked in fluorescent liquid or coated with fluorescent powder are imaged by the visual inspection system 4, the acquired image can be made clearer, the defective part can be distinguished more easily, and the inspection can be improved. accurate.

[0039] Further, the conveying device is a vibrating screen 1 and a conveyor 2, wherein the vibrating screen 1 is a vibrating sorting mechanism, which can arrange the bearing parts to be tested in a row and send them to the conveyor 2 , The conveyor 2 transports the bearing components to be tested to the testing area.

[0040] In the embodiment of the present invention, the vibrating screen 1 is a vibrating sorting mechanism, which can arrange the chaotic bearing parts to be tested in a row and send them to the conveyor 2 one by one. At the same time, the vibrating screen 1 is transported to The speed of detecting bearing components can be adjusted to meet the different detection speed requirements of bearings of different specifications.

[0041] Further, the conveyor 2 adopts a timing belt to convey the bearing components to be tested.

[0042] In this way, while the bearing parts to be tested are transported forward on the timing belt, operations such as visual inspection, rejection of unqualified products, and entry of qualified products into the basket can be completed. Preferably, the timing belt can be a belt to make the conveying process stable , No noise, simple structure and low cost.

[0043] Further, the visual inspection system 4 is placed in an independent environment and equipped with an illumination lamp. With the cooperation of the illumination lamp, the visual inspection system 4 can obtain a clear image.

[0044] In the embodiment of the present invention, by placing the vision detection system 4 in an independent environment and equipped with illumination lamps, a better image detection effect can be achieved, no other interferences during the detection process can be ensured, and image acquisition can be more accurate. In particular, the illuminating lamp and the bearing component to be tested after immersed in fluorescent liquid or coated with fluorescent powder cooperate with each other to achieve a better detection effect, make the image clear and the detection accurate.

[0045] Preferably, the outlets of the qualified product funnel 6 and the unqualified product funnel 7 are equipped with material baskets for storing qualified products and non-qualified products respectively.

[0046] In the embodiment of the present invention, by setting the material basket, the qualified products and the unqualified products are stored separately, so as to avoid the chaotic storage of parts or the confusion between the two.

[0047] Further, before the step (1), it also includes the following steps:

[0048] The conveying device, the position detection sensor 3, the visual detection system 4, and the defective product rejection mechanism 5 are respectively connected to the electronic control system 8 and operate according to the logical relationship set by the electronic control system 8.

[0049] In order to ensure the accuracy of the detection, the electronic control system 8 controls the conveying device, the position detection sensor 3, the visual detection system 4 and the non-conforming product rejection mechanism 5, so that the entire control process can run in accordance with the logical relationship and avoid bearing zero caused by operating errors. Incorrect component detection.

[0050] Therefore, the present invention adopts a visual way to detect the surface defects of the bearing parts, the imaging is clear, the detection accuracy can be ensured, and the continuous detection belt conveying structure is adopted to improve the detection efficiency.

[0051] The foregoing descriptions are only illustrative specific embodiments of the present invention, and are not used to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the protection scope of the present invention.
