Description

Technical Field

[0001] The utility model belongs to the technical field of small mold detection devices, and more specifically, particularly relates to a mold detection device. Background Art

[0002] In manufacturers that mass-produce small molds, it is necessary to conduct various tests on the mass-produced small molds, and they can only be shipped after confirming that all aspects are qualified. In terms of appearance inspection, these mass-produced small molds are usually inspected using automatic appearance defect detection equipment. Existing automatic appearance defect detection equipment is usually composed of an image acquisition camera, a central processing device, and a chain conveyor device. During the inspection, the small mold is placed above the chain conveyor device. While the small mold is being transmitted, the image acquisition camera collects images of each surface of the small mold. The three-dimensional point cloud data collected by the image acquisition camera is transmitted to the central processing device. The central processing device will process the three-dimensional point cloud data and extract features such as texture, shape, and color. Through a pre-established model or algorithm, the extracted feature information is analyzed and compared, and defects in the image are identified and fed back.

[0003] For example, the present invention with application number 201910483810.X provides a mold detection device, including: an image acquisition unit, a detection unit, a transmission component and an installation component, the installation component is set with the transmission component, the detection unit and the image acquisition unit are installed on the installation component, and the image acquisition unit is electrically connected with the detection unit; the transmission component is used to sequentially transmit the mold; the detection unit is used to detect the arrival signal of the mold and send it to the image acquisition unit; the image acquisition unit is used to collect image information of the mold after receiving the arrival signal. The mold detection device provided by the present invention can avoid the image acquisition unit from collecting too much useless image information, improve the working efficiency and working effect of the image acquisition unit, and thus improve the working efficiency of the mold detection device.

[0004] Based on the above, during inspection, the small mold is transmitted through a chain conveyor, and then the image acquisition camera collects images of each surface of the small mold. The inspector first needs to place the small mold on one end of the chain conveyor. After the image acquisition camera has acquired the image, the small mold will be transmitted to the other end of the chain conveyor, and then the inspector removes the small mold from the other end of the conveyor. When conducting batch inspection of small molds and the length of the chain conveyor is long, the inspector needs to reciprocate at both ends of the chain conveyor to pick and place. The process is cumbersome and wastes manpower, which affects the efficiency of inspecting batches of small molds. Utility Model Content
