However, there are some disadvantages of multi-stroke strippers, these drawbacks include: every time the mold is opened, before the mold is closed again to injection mold the next part, the cycle of multi-stroke stripper will need to be replaced. More time to eject the hardened plastic part; and this multiple cycle work will increase the wear and tear of the ejector and mold
Typically, it is difficult to control the lighting environment in a manufacturing environment due to the presence of overhead fluorescent lights, skylights, overhead cranes, operators and many other factors
Therefore, during the process of acquiring an image and comparing it with the previous image, even a small change in the lighting environment will cause the detection job to be falsely rejected

A part-forming machine having an infrared vision inspection system and a method for verifying the presence, absence and quality of molded parts therein wherein an infrared vision system is utilized. At least one infrared sensor (310) is used in conjunction with a part-forming machine, wherein the infrared sensor (310) takes an image of the part (22) and / or mold (12) based on infrared radiation emitted by the part / mold. Based on the infrared image, the part-forming machine responds thereto by activating ejectors (56, 58) and reimaging the part / mold, or continuing with the next molding step.
Description
technical field [0001] The present invention generally relates to a part forming machine, and more particularly, the present invention relates to a part forming machine with an infrared detection function and a method for inspecting the presence and quality of molded parts in the forming machine. Background of the invention [0002] The component forming industry is one of the largest industries in the world in terms of total tax revenue and total number of employees. As a multi-billion dollar industry, even a very small improvement in the manufacturing process can have huge benefits, thereby reducing costs. Currently, many methods and machines have been devised for making components. For example, parts are typically molded, molded and / or manufactured by thermoforming, the most widely used of which is probably the mold. There are many ways to mold parts such as stretch blow molding, extrusion blow molding, injection blow molding, vacuum molding, rotational molding and inje...
