Abstract

The invention relates to a screw detection device, in particular to a screw thread detection device and detection method, including a workbench, which is provided with a clamping mechanism for clamping the screw to be tested, and an X-direction clamp is also provided on the workbench. For the main camera, a first backlight panel is arranged opposite to the main camera in the X direction, and an auxiliary camera in the Y direction is arranged on the workbench, and a second backlight panel is arranged on the opposite side of the auxiliary camera in the Y direction. The present invention adopts two vertical direction cameras of X and Y The acquisition and correction method of parameters such as screw tooth shape under the condition of backlight is carried out, and the automatic image detection of thread is realized.

Description

technical field [0001] The invention relates to a screw detection device, in particular to a thread pass-through detection device and a detection method. Background technique [0002] Screws are one of the six simple machines invented by human beings. They play an important role in the field of connector products and are often used for the installation of connection accessories and the fixing of cables. Screws have the advantages of easy assembly and easy disassembly, making them used in various fields. If the screw has problems such as no thread, cracking, and size out of tolerance, it will seriously affect the installation and use of the connector product. The current comprehensive detection method is based on the Taylor inclusion principle, using the through-end thread gauge to detect the rotatability of the thread, and using the stop thread The single-item manufacturing deviation is used in gauge testing; however, the single-item detection method is mainly used to analy...
