[0002] Visual inspection is to use machines instead of human eyes to make measurements and judgments. Visual inspection refers to converting the captured target into image signals through machine vision products, transmitting them to a dedicated image processing system, and converting them into digital signals based on pixel distribution, brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on site based on the judgment results. It is a valuable mechanism for production, assembly or packaging, and it has immeasurable value in detecting defects and preventing defective products from being delivered to consumers.

[0003] The patent number CN202320162248.2 discloses a visual inspection device for the appearance of injection molded parts, including a main body, which is the main load-bearing part of the device, an infrared counter, which is installed on the top of the U-shaped plate, a transmitter, which is installed on the top left end of the main body, and a receiving head, which is installed on the top right end of the main body. The utility model overcomes the shortcomings of the prior art. By setting an infrared counter, a transmitter and a receiving head, the injection molded parts are moved to a suitable position as the conveyor belt rolls, and the appearance is visually inspected by the detection mechanism. After the inspection, the injection molded parts enter the receiving box for centralized collection. If an object passes between the transmitter and the receiving head, the light is blocked, and a pulse signal is output to trigger the counting circuit, so that the infrared counter records, which is convenient for counting the injection molded parts after the inspection. Moreover, this process is automatic counting, which saves labor costs.

[0004] The above device has certain shortcomings when it is used: when the above device is working, the injection molded parts after inspection are put into the receiving box for centralized collection.

[0024] Beneficial effects:

[0025] (1) The visual inspection jig for injection molded parts is driven by a controller to control a driving motor, a transmission roller, and a transmission belt. The controller controls the inspection equipment and a visual camera to work, the fill light is turned on, the injection molded parts are placed on the transmission belt, and the inspection equipment and the visual camera perform visual inspection on the injection molded parts. If the injection molded parts meet the standards, the controller controls the electric push rod at the rear to push the inclined push plate and the protective pad forward, and the inclined push plate at the rear drives the limit rod to move on the outer wall of the fixed frame. After the inclined push plate contacts the rear wall of the limit seat, the injection molded parts contact the protective pad at the rear and are separated by the separation plate, passing through the front side of the lower part of the U-shaped frame and falling into the front part of the inner wall of the collection box, so that when the injection molded parts are inspected by the visual inspection equipment to see if they meet the standards, the intact injection molded parts and the defective products can be separated and processed. After the batch of injection molded parts are inspected, there is no need to directly perform secondary sorting, which is very convenient to use.

[0026] (2) The visual inspection fixture for injection molded parts uses an electric push rod to push the tilting push plate and drive the movable rod to move. The movable rod drives the movable seat and the cleaning pad to wipe the bottom of the visual camera clean. The injection molded parts passing through the bottom of the U-shaped frame block the infrared rays emitted by the receiving head and the transmitting head. Each time the infrared rays are blocked, the counter will be recorded once and the real-time data will be transmitted to the controller through the data line. When the batch work is completed, the specific number of injection moldings that meet the standards and those that do not meet the standards in the entire batch can be viewed through the controller, so that when the entire device is used, the visual camera can be cleaned, and when a large number of inspections are completed, the specific data of the injection molded parts can be understood.

[0041] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0042] During operation, firstly, the controller 4 controls the driving motor 14 to start working, and the power shaft of the driving motor 14 drives the corresponding transmission roller 12 to rotate. When the transmission roller 12 rotates, it drives the transmission belt 13 to perform transmission work. The controller 4 controls the detection device 9 and the visual camera 10 to start working, and turns on the fill light 15. The injection molded part is placed on the outer wall of the transmission belt 13 and placed at the lower part of the visual camera 10. Through the cooperation of the detection device 9 and the visual camera 10, the visual inspection is gradually carried out. If the injection molded part meets the standard, the controller 4 controls the electric push rod 52 at the rear to push the inclined push plate 54 and the protective pad 55 forward. The inclined push plate 54 at the rear moves At the same time, it drives the limit rod 53 to move on the outer wall of the fixing frame 51 to avoid the position deviation of the inclined push plate 54 when moving, so that the inclined push plate 54 and the protective pad 55 start to move forward until the inclined push plate 54 contacts the rear wall of the limiting seat 510, so that the injection molded parts transported by the transmission belt 13 contact the protective pad 55 at the rear and are separated by the separation plate 57, pass the position of the lower front side of the U-shaped frame 56, and fall into the position of the front part of the inner wall of the partition plate 59.

After the injection molded parts are separated by the partition plate 59, the front part of the inner wall of the collection box 58 is used to place the injection molded parts that meet the standards, and the front part of the inner wall of the collection box 58 is used to place the injection molded parts that do not meet the standards. Every time the electric push rod 52 pushes the inclined push plate 54 to move, it will drive the movable rod 71 to follow the movement. The movable rod 71 drives the movable seat 72 and the cleaning pad 73 to move while moving. The cleaning pad 73 will wipe the bottom of the visual camera 10 clean when it moves to prevent dust and impurities from affecting the normal operation of the visual camera 10. When the injection molded parts passing the bottom of the U-shaped frame 56 block the infrared rays emitted by the receiving head 62 and the transmitting head 63, each time the infrared rays are blocked, the infrared counter 61 will be recorded once and the real-time data will be transmitted to the controller 4 through the data line.When the batch work is completed, the specific number of injection moldings that meet the standards and those that do not meet the standards can be checked through the controller 4. After the inspection, manual sorting is no longer required. The entire device is more convenient to use.
