Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] See also Figure 1 , 2The utility model provides a technical solution: an optical automatic detection and screening machine for missing rivets of multi-contact components, mainly composed of a cabinet 1, a cabinet 2, a product feeding module 3, a product conveying module 4, a product detection module 5, a discharge pipe 1 6 and a discharge pipe 2 7, wherein the product feeding module 3 is installed on the cabinet 1, and the product conveying module 4, the product detection module 5, the discharge pipe 1 6 and the discharge pipe 2 7 are all installed on the cabinet 2 2, the product feeding module 3 can neatly and regularly convey a number of multi-contact component products to be screened and detected to the product conveying module 4, and a number of multi-contact components to be screened and detected The product will move on the product conveying module 4. During the movement, the product inspection module 5 will perform visual inspection on the multi-contact component products one by one. After the inspection, the multi-contact component products on the product conveying module 4 will be divided into two types: good products and defective products. The good products will be directly conveyed to the discharge pipe 7 by the product conveying module 4, while the defective products will be blown into the inside of the discharge pipe 6 during the conveying process, thereby realizing a complete set of automatic inspection and screening of multi-contact component products. Compared with the existing commonly used manual methods, the inspection efficiency is greatly improved and the inspection cost will be reduced accordingly.

[0040] In order to further explain the product feeding module 3, the product conveying module 4 and the product detection module 5 in this embodiment, please refer to Figure 3 , 4 , 5;

[0041] The product feeding module 3 is composed of a feeding bin 31, a vibrating material tray 32 and a straight vibrating track 33. During the feeding process, a plurality of multi-contact component products are stored inside the feeding bin 31, and the inside of the feeding bin 31 is set as a landslide-like slope, and the lowest point of the landslide corresponds to the outlet of the feeding bin 31, so that the multi-contact component products can enter the vibrating material tray 32 without power. The structure and principle of the vibrating material tray 32 are existing well-known technologies, which can neatly arrange and transport the scattered products to its outlet by means of vibration, and then the straight vibrating track 33 also transports the products to the belt conveyor 41 by means of vibration;

[0042] The main structure of the product conveying module 4 is a belt conveyor 41, which can synchronously convey the products conveyed by the straight vibration track 33. During the conveying process, the products will pass through the photoelectric sensor 42, the rectangular light source 43 and the blowing nozzle 44 in sequence. The photoelectric sensor 42 includes a light emitter and a light receiver. When working, a light path will be formed between the two. If a product passes between the light emitter and the light receiver, the propagation of the light path will be blocked. At this time, the photoelectric sensor 42 will generate an electrical signal, which will be transmitted to the controller (or single-chip microcomputer), and the controller To control the corresponding equipment to work (CCD camera 53, air pump connected to blowing nozzle 44), the visual image of the product will be collected by CCD camera 53 during the transportation process, and the recognition area will be compared with the preset good product within the recognition area, so as to judge whether the product is good or bad. Good products will be transported to discharge pipe 2 7 by belt conveyor 41, while bad products will pass through blowing nozzle 44 during the transportation process. Blowing nozzle 44 generates airflow to blow the bad products to discharge pipe 1 6. Here, blowing nozzle 44 is connected to the air pump through an air pipe, and the air pump is controlled by the controller mentioned above;

[0043] The basis of the product inspection module 5 is a bracket 51, on the top of which a height adjustment seat 52 is installed, and a CCD camera 53 is fixed on the mounting end surface of the height adjustment seat 52. The CCD camera 53 is located directly above the product conveying path of the belt conveyor 41. The height adjustment seat 52 can adjust the height of the CCD camera 53, which is an existing well-known technology and will not be described in detail here. In order to change the visual image effect collected by the CCD camera 53, the CCD camera 53 is also equipped with a light source 55 with a ring structure. The light source 55 is located directly below the CCD camera 53 and is supported by a bracket 54.

[0044] In summary, in the multi-joint assembly missing rivet optical automatic detection and screening machine, the product is placed in the feed bin 31, the equipment is started to the running state, and the feed bin 31, the vibrating material plate 32 and the straight vibrating track 33 are turned on. The product is fed into the vibrating material plate 32 through the feed bin 31, continuously moves on the spiral track, and is corrected by the correction mechanism of the vibrating material plate 32 in multiple steps. The product enters the straight vibrating track 33 and is sent to the belt conveyor 41. The product passes directly under the CCD camera 53 and is instantly identified. Within the identification area, the identification area is compared with the preset good products. The defective products outside the set value range are blown into the discharge pipe 1 6, and the products within the set value range are judged as good products. The products continue to flow forward into the discharge pipe 2 7, so as to achieve the purpose of screening the products.
