Injection molding robot with visual mold monitor

Abstract

The invention relates to visual detection equipment, in particular to an injection molding robot with a visual mold monitor. The injection molding robot with the visual mold monitor can completely eliminate the serious visual distortion and blind areas of detection and protection of a traditional mold monitor, and has the characteristics of having high detection accuracy, being small and flexible,being capable of moving arbitrarily with a coordinate robot and integrating a mold monitoring protector and product quality visual inspection. The visual monitor is directly arranged on the coordinate robot. After the injection molding machine is opened, the coordinate robot descends to the interior of the mold with the monitor, can move arbitrarily and repeatedly according to detection key partsand takes photos continuously without dead angles or visual distortion; and after the shooting distance is shortened, the image definition generally increases by more than 200%, so that whether residues exist in a product and whether the product is taken out completely can be detected, whether metal and other plug-in components or pins inserted into the mold are installed in place can also be detected, whether the shaped product has quality defects such as incomplete filling, shrinkage, black spots and different colors is detected, the visual distortion is eliminated, the photos taken are clear and complete, and meanwhile the type of visual cameras is not limited.

Description

technical field [0001] The invention relates to visual detection equipment, in particular to an injection molding robot with a visual mold monitor. Background technique [0002] Precision and expensive molds in injection molding, blister molding, blow molding, and die-casting industries are very easy to damage the mold after closing the mold when the molded product is not completely taken out and the metal and other precision plug-in PIN pins are not inserted in place, resulting in major losses such as production shutdown and maintenance. To solve this industry problem, the mold monitor protector industry was born. The current mold monitor protector industry always installs the camera outside the mold, so that the angle of the photos taken in this way is very large, the visual distortion is very large, and the mold cannot be photographed. There are a lot of visual blind spots that cannot be photographed at all, especially the key parts of the mold that are vulnerable to dama...

[0002] Precision and expensive molds in injection molding, blister molding, blow molding, and die-casting industries are very easy to damage the mold after closing the mold when the molded product is not completely taken out and the metal and other precision plug-in PIN pins are not inserted in place, resulting in major losses such as production shutdown and maintenance. To solve this industry problem, the mold monitor protector industry was born. The current mold monitor protector industry always installs the camera outside the mold, so that the angle of the photos taken in this way is very large, the visual distortion is very large, and the mold cannot be photographed. There are a lot of visual blind spots that cannot be photographed at all, especially the key parts of the mold that are vulnerable to damage such as sliders and inclined roofs, which are difficult to detect and fail to protect; The image is blurred and the detection and protection effect is poor

[0003] Injection molding, blister molding, blow molding, and die-casting industries require quality visual inspection of quality defects such as lack of material, shrinkage, black spots, and different colors to determine qualified and defective products. The current practice is to use manual inspection. In addition to the high labor cost, it is extremely difficult to avoid missed inspections and false inspections, resulting in a large number of rework and re-inspection; second, the purchase of special testing equipment, in addition to the high cost, can only detect certain types of specific products, and the versatility is poor. Once the product is discontinued, the equipment can only be scrapped, resulting in heavy loss of assets
