Description

Technical Field

[0001] The utility model relates to the technical field of visual inspection devices, in particular to a visual inspection device for the molding quality of a precision injection mold product. Background Art

[0002] Visual inspection is to use machines to replace 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 equipment action on site based on the judgment results. It has immeasurable value in detecting defects and preventing defective products from being delivered to consumers.

[0003] The patent document with the prior art publication number CN115479941B provides a visual inspection device for industrial product quality inspection, including a visual inspection instrument and a conveyor belt, the inner end of the visual inspection instrument is provided with a positioning shaft, the outer end of the positioning frame is provided with a camera frame, the inner end of the conveyor belt is provided with a hollow groove, and a shifting component. After the camera of a certain position on the camera frame is removed, the remaining cameras are automatically evenly distributed. The shifting component includes a cross-connecting shaft and a slide fixedly installed at the four corners of the cross-connecting shaft, which is used to drive the camera to slide. The inner end of the slide is provided with a sliding rod, and the inner ends of the sliding rod and the slide are respectively provided with a first spring and a second spring, which are used to drive the sliding rod and the slide. The present application solves the problem that the current visual inspection design performs rotation detection on gears and automatically adjusts the spacing of the camera position after damage and removal without affecting the inspection process.

[0004] However, during the use of the existing visual inspection device for the molding quality of precision injection mold products, the product is placed on a conveying device for transportation, and the visual inspection device will photograph the product to complete the quality inspection. Since the product is moving during inspection, when the visual inspection device is stuck, the shooting component cannot move, resulting in the shooting component missing the product inspection when no picture is taken, or the device stops running, thereby affecting the inspection efficiency. For this reason, we propose a visual inspection device for the molding quality of precision injection mold products. Utility Model Content
