Description

Technical Field

[0001] The present invention relates to the technical field of industrial product visual inspection, and in particular to a visual inspection device for an industrial production line. Background Art

[0002] Industrial visual inspection is a technology that uses machine vision technology to detect the quality of industrial products and production processes. It converts the captured target into an image signal through a machine vision product (such as an image capture device), and then transmits it to a dedicated image processing system. The image processing system performs various operations on these signals to extract the characteristics of the target, and judges whether the quality of the product and the production process are normal based on these characteristics. Industrial visual inspection is mainly used in quality inspection, dimension measurement, defect inspection, identification and positioning. It can detect the surface quality of products, such as scratches, dirt, bright spots, missing corners and protrusions, and can also detect the size and shape of products, as well as identify product logos and labels. In addition, industrial visual inspection can also be used for automated control of production lines to realize automated inspection, sorting, counting and other functions, and improve production efficiency and product quality. Compared with traditional manual inspection, industrial visual inspection has the advantages of non-contact, fast speed, high precision, and strong on-site anti-interference ability, which can greatly improve detection efficiency and accuracy and reduce the possibility of missed detection and false detection. At the same time, industrial visual inspection can also be automated and intelligent, reduce labor costs and improve production efficiency. It is one of the indispensable important technologies in modern industrial production.

[0003] Among them, CN215525501U discloses a visual inspection device for industrial production lines, including a visual inspection device, which includes a conveying mechanism, a detection mechanism, a flipping mechanism and a cleaning mechanism. Conveying mechanisms are arranged at both ends of the visual inspection device, a detection mechanism is arranged at the top of the conveying mechanism, a flipping mechanism is arranged in the middle of the conveying mechanism, and a cleaning mechanism is arranged at the bottom of the conveying mechanism. The visual inspection device for industrial production lines is provided with a flipping mechanism installed between the conveying mechanisms. When the conveyor belt conveys the inspected parts to the L-shaped plate, the infrared sensor is connected to the electric hydraulic rod through the line, so that the electric hydraulic rod contracts, thereby driving the L-shaped plate to flip, and the flipping of the L-shaped plate drives the inspected parts to flip, and then the inspected parts are conveyed to the bottom of the camera through the conveyor belt, so that the camera can capture images of multiple surfaces of the inspected parts, thereby improving the inspection efficiency.

[0004] In the prior art, such as CN216081401U, the bottom surface of the part to be inspected is turned over to facilitate the camera to collect information on other surfaces of the part, and a roller brush is installed at the bottom of the conveyor belt to clean the dust on the conveyor belt in real time. However, during use, only the plate-type products on the industrial production line can be visually inspected. When encountering vertical products, the four sides of the outer wall cannot be visually inspected, which greatly increases the limitations of the device during use. In addition, the background color during visual inspection cannot be adjusted and replaced according to the color of the product surface during inspection, which will affect the quality and speed of visual inspection when the product is similar to the inspection background on the device. At the same time, a unified moving path is still used when discharging the products after visual inspection, resulting in the need for staff to manually classify the defective and defective products detected by visual inspection, which increases the workload of personnel and reduces the functionality of the device. To this end, we have designed a visual inspection device for industrial production lines to solve the above problems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a visual inspection device for industrial production lines, which solves the problem that the prior devices are unable to perform visual inspection on the four sides of the outer wall of a vertical product, reduces the limitations of the device, and can replace the background color during visual inspection with a contrasting color according to the color of the product.

At the same time, normal products and defective and substandard products detected by visual inspection can be classified and discharged, avoiding the problem of increased manpower and loss costs.

Among them, the conductive ring 4010 can transmit signals and supply power to the side detection lens 701 and the horizontal electric push rod 404 and the longitudinal electric push rod 406 when the rotating rod 402 rotates, thereby avoiding the situation where the signal line and the conductive line are entangled when the rotating rod 402 rotates.

[0037] Furthermore, a rotating motor 408 is fixedly installed on the top of the support frame 401, and a driving gear 409 extending into the interior of the support frame 401 and used in conjunction with the rotating gear 403 is fixedly installed at the output end of the rotating motor 408. The rotating motor 408 can drive the rotating gear 403 and the rotating rod 402 to rotate through the driving gear 409, thereby facilitating the side inspection lens 701 to visually inspect the four sides of the outer wall of the product.

[0038] Furthermore, multiple groups of vacuum suction cups 302 penetrating the bottom background plate 303 are fixedly installed on the top of the lifting platform 301, and the vacuum suction cups 302 are connected to external vacuum equipment through air pipes. The vacuum suction cups 302 can be adsorbed and fixed on the bottom of the lifting platform 301 when the lifting platform 301 lifts the product through the externally connected vacuum equipment, thereby increasing the stability of the device during visual inspection of the product and avoiding the product from shaking and being unstable.

[0039] Furthermore, two sets of mounting plates 305 are fixedly mounted on the front and back of the bottom background plate 303, and two sets of mounting grooves 304 for use with the mounting plates 305 are arranged on the front and back of the lifting platform 301. The mounting plates 305 are fixedly mounted in the mounting grooves 304 by bolts, and the bottom background plate 303 can be fixed during operation, thereby increasing the stability of the bottom background plate 303 during operation.
