Description

Technical Field

[0001] The utility model relates to the field of anti-error vision inspection devices, and particularly to an anti-error vision inspection device with an automatic sheet discharging function. Background Art

[0002] In the process of mirror production, visual inspection is used to judge whether the finished products are qualified. Visual inspection means that the target to be captured is converted into an image signal by a machine vision product (i.e., an image acquisition device, which is divided into two types: CMOS and CCD), and then transmitted to a dedicated image processing system. According to the pixel distribution, brightness, color and other information, it is converted into a digital signal; the image system performs various operations on these signals to extract the features of the target, and then controls the on-site equipment actions according to the discrimination results;

[0003] In the prior art, a Chinese utility model patent with the publication number of CN215727643U discloses an appearance inspection device based on machine vision processing. This utility model can automatically adjust and clamp an object through a clamping cylinder, and at the same time drive the object to rotate by using a first rotating motor, so as to ensure that the object can be detected in all directions and at multiple angles. After the visual inspection is completed, the control center compares the detected image with the image system to judge whether the finished product is qualified. For the defective products generated, they need to be removed. In the existing process of removing defective products, since the height between the collection box and the defective products is relatively high, the objects are easily damaged when being pushed into the collection box, resulting in the complete damage of the defective products. However, some defective products may be restored to qualified finished products through subsequent processing, so materials are wasted and improvement is needed. Summary of the Utility Model

Detailed Embodiments

[0021] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Such as Figure 1 , Figure 2 and Figure 5As shown in the figure, an anti-error vision inspection device with an automatic film arranging function includes a conveying rack 1. On one side inside the conveying rack 1, a driving roller 3 is movably installed. On the other side inside the conveying rack 1, a driven roller 4 is movably installed. A conveyor belt 5 is movably installed on the driving roller 3 and the driven roller 4. An automatic film arranging assembly 7 is movably connected to the conveying rack 1. The automatic film arranging assembly 7 includes a collecting cover 701, a PLC controller 702, an industrial camera 703, a first cylinder 705, a pushing plate 706, a collecting rack 708, a sliding rod 711, a moving carrier plate 712, and a screw rod 713. The collecting cover 701 is fixedly connected to the conveying rack 1. The PLC controller 702 is fixedly connected to the outer side of the collecting cover 701. The industrial camera 703 is fixedly connected inside the collecting cover 701. The first cylinder 705 is fixedly connected to one side of the collecting cover 701. The pushing plate 706 is fixedly connected to the output shaft of the first cylinder 705. Support legs 2 are fixedly connected to the bottom surface of the conveying rack 1. A first stepping motor 6 is fixedly connected to the side surface of the conveying rack 1, and the output shaft of the first stepping motor 6 is fixedly connected to the driving roller 3. The automatic film arranging assembly 7 further includes a displacement sensor 704 and a discharging opening 707. The displacement sensor 704 is fixedly connected inside the collecting cover 701. The discharging opening 707 is formed on the collecting cover 701, and the collecting rack 708 is located on the side of the discharging opening 707. When the PLC controller 702 is started, the conveyor belt 5 is rotated to transport the finished products. When the displacement sensor 704 detects a finished product, a signal is transmitted to the PLC controller 702, thereby controlling the conveyor belt 5 to stop, so that the finished product is located below the industrial camera 703, and image acquisition of the finished product is performed. The image is transmitted to the PLC controller 702 for judgment. When it is determined that the product is unqualified, the PLC controller 702 controls the first cylinder 705 to start, so that the pushing plate 706 pushes the finished product to move sideways, thereby excluding the defective products.

[0023] As Figure 1 , Figure 3 and Figure 4As shown, the collecting frame 708 is fixedly connected to the side position of the collecting cover 701, the sliding rod 711 is fixedly connected to the side position of the collecting frame 708, the screw 713 is movably installed at the other side position of the collecting frame 708, and the movable carrier 712 is movably installed on the sliding rod 711 and the screw 713. The automatic film arrangement component 7 also includes a No. 1 welding plate 709 and a No. 2 welding plate 710. The No. 1 welding plate 709 and the No. 2 welding plate 710 are fixedly connected to the collecting frame 708. The collecting frame 708 is welded and installed with the collecting cover 701 and the conveying frame 1 through the No. 1 welding plate 709 and the No. 2 welding plate 710 respectively. The automatic film arrangement component 7 also includes a bearing 714 and a No. 2 stepping motor 715. The screw 713 is movably installed with the collecting frame 708 through the bearing 714. The No. 2 stepping motor 715 is fixedly connected to the collecting frame 708, and the output shaft of the No. 2 stepping motor 715 is connected to the screw One end of the rod 713 is fixedly connected, and the automatic sheet arrangement component 7 also includes a screw hole 716 and a slide hole 717. The screw hole 716 and the slide hole 717 are opened on the movable carrier 712. The movable carrier 712 is movably installed with the screw rod 713 and the slide rod 711 through the screw hole 716 and the slide hole 717. When the distance between the movable carrier 712 and the conveyor belt 5 is too long, when defective products fall on the movable carrier 712, they are easily damaged. The second stepper motor 715 is controlled by the PLC controller 702 to rotate the screw rod 713, and the movable carrier 712 on the screw rod 713 and the slide rod 711 is controlled to move. When defective products are stored on it and the defective products are removed again, the height of the movable carrier 712 and the defective products thereon is lowered again to make the height level again, so that the next defective product can slide into the upper position of the first defective product easily, so that the defective product is not easy to be damaged when it is pushed out.

[0024] It should be noted that the present utility model is an anti-error vision inspection device with an automatic sheet discharging function. The PLC controller 702 controls the rotation of the first stepping motor 6, causing the conveyor belt 5 to rotate and transporting the finished mirror products on the conveyor belt 5. When the finished mirror products are transported into the acquisition cover 701 and the displacement sensor 704 detects the finished mirror products, it transmits a signal to the PLC controller 702. The PLC controller 702 stops the first stepping motor 6, positioning the finished product below the industrial camera 703. The industrial camera 703 captures an image of the finished product and transmits the image to the PLC controller 702. If the finished product is qualified, the first stepping motor 6 is controlled to start again, causing the conveyor belt 5 to continue moving and transporting the finished product. When the finished product is unqualified, the PLC controller 702 controls the first cylinder 705 to start, causing the push plate 706 to push the finished product to move. At the same time, the PLC controller 702 controls the movable carrier plate 712 to move. For example, initially, the movable carrier plate 712 is higher than the conveyor belt 5 by the height of one finished product. When the first cylinder 705 starts, the second stepping motor 715 is started, causing the screw 713 to rotate and pushing the movable carrier plate 712 to move down by the height of one finished product to be level with the conveyor belt 5. Then, the push plate 706 pushes the finished product onto the movable carrier plate 712. At this time, the movable carrier plate 712 and the finished product on it are higher than the conveyor belt 5. When subsequent defective products are detected, when the push plate 706 pushes the defective product to continue moving, the movable carrier plate 712 is controlled by the second stepping motor 715 to move down by the height of one finished product again, facilitating the stacking of the second defective product on the first defective product, making it less likely to be damaged when the defective product is pushed out and facilitating subsequent rework.
