Embodiment Construction

[0011] The automatic inspection method and inspection system for injection molded workpieces provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] see figure 1 , the injection molded workpiece automatic inspection method provided by the embodiment of the present invention includes the following steps;

[0013] (a) using a transfer device to transfer the injection molded workpiece to be inspected to an inspection area;

[0014] (b) in the detection area, using a light source to project light onto the surface of the injection molding workpiece, and using an image sensing device to sense the amount of light reflected from the surface of the injection molding workpiece;

[0015] (c) rotating the light source and image sensing device relative to the injection molding workpiece, so that the image sensing device senses reflected light from multiple locations around the surface of the injection molding work...

Abstract

The invention provides an automatic checking method for an injection molded work piece, which comprises the following steps: using a transporter to transport an injection molded work piece to be checked to a check area; using a light source to project rays to the surface of the injection molded work piece in the check area, and using an image sensing device to sense quantity of light reflected back from the surface of the injection molded work piece; making the light source and the image sensing device rotate relative to the injection molded workpiece; using a processor to receive and judge whether reflected light quantity information sensed by the image sensing device is within a qualified range, so as to judge whether the injection molded work piece has poor injection molded defect; if yes, using a poor work piece removing device first to remove the injection molded work piece which has the poor injection molded defect, and then using the transporter to continuously transport the next injection molded work piece to be checked; if not, making the injection molded work piece passing the check enter a finished product station, and making the transporter continuously transport the next injection molded work piece to be checked.

Description

technical field [0001] The invention relates to an automatic inspection method for injection molding workpieces and an automatic inspection system for injection molding workpieces. Background technique [0002] With the development of modern industry, especially the precision industry, injection molding machines (also known as injection machines) are widely used in injection molding plastic, glass, metal and other materials. [0003] As stated in the article "Causes of Molding Defects and Solutions" published in the first issue of "Rock Drilling Machinery Pneumatic Tools" in 2006, during the injection molding process, due to the program control or operation of each part of the injection machine and the mold does not meet the requirements, It is often easy to cause injection molding defects such as burrs, shrinkage, flow marks and strains on injection molding workpieces. Therefore, inspection of workpieces is essential after injection molding. [0004] At present, the inspe...
