Abstract

The present invention relates to a CCD phase detection device and phase detection method for a multi-component assembly and pressing product. The CCD camera can rotate 180° under the action of a rotating mechanism to collect images of the assembled pressed parts from at least the front, top and back of the assembled pressed parts. A component vibration mechanism is connected below the assembly jig. The component vibration mechanism can not only rotate the assembly jig and the assembled pressed parts by 90°, so that the CCD camera can collect images of the two sides of the assembled pressed parts, but also make the assembled pressed parts on the assembly jig vibrate to test the pressing quality of the assembled pressed parts, and the control unit automatically determines whether it is a good product or a bad product based on the images of the assembled pressed parts before and after the vibration taken by the CCD camera. The present invention uses a CCD camera to realize phase acquisition of the assembled pressed parts at multiple angles, and more component conveying devices can be set to assemble more complex assemblies. Multi-angle images can also be collected to ensure that the quality of the inspection is not reduced.

Description

Technical Field

[0001] The invention relates to the field of post-processing of formed products, and in particular to a CCD phase detection device and a phase detection method for a multi-component assembled and pressed product. Background Art

[0002] In the prior art, automated detection has been implemented to distinguish good and bad components from a huge number of different types of components.

[0003] For example: Prior art Chinese invention patent: A detection system for multi-component assembly and pressing products (application number: 2024112966825). It includes an annular guide rail mechanism, which drives multiple assembly jigs to move in a cycle, and a plastic assembly base is placed on each assembly jig. The plastic assembly base has multiple mounting parts, and multiple component conveying devices are arranged around the annular guide rail mechanism. Each component conveying device can install a component on a mounting part of the plastic assembly base. Multiple components are assembled with the plastic assembly base to form an assembly. The assembly is pressed with the plastic assembly base by a clamping mechanism. The pressed assembly is collected by one or more component missing deformation CCD detection machines for appearance image collection. The control unit determines whether the appearance of the assembly is qualified based on the appearance image, and the qualified assembly is unloaded by a good product unloading machine.

[0004] However, this technology also has defects: First, the annular guide mechanism must occupy more space because multiple component conveying devices need to be arranged around it, especially when the assembly is more complex, which will inevitably lead to a reduction in the number of CCD phase detection devices. When the number of CCD phase detection devices is insufficient, it will be impossible to use more different phase angles for image acquisition, so the quality of the assembly itself and the pressing cannot be guaranteed. Second, multiple components are pressed together to form an assembly, and whether the pressing is firm and stable cannot be judged by the CCD phase detection device or the judgment is inaccurate.

When one of the differences between the two comparisons exceeds the preset value, it means that the combined pressed part (5) is a defective product.

6. The phase detection method of the CCD phase detection device for multi-component assembly and pressing products according to claim 5, characterized in that: Step 10: The control unit starts the rotating mechanism, and the CCD camera (41) is located on the top surface of the combined pressed part (5) under the action of the rotating mechanism, so that the CCD camera (41) will not block the combined pressed part (5) that has been tested from moving forward; Step 11: When testing the next combined pressed part (5), repeat steps 1-10.
