Problems solved by technology

[0003] Since the wear of the riveting die is a microscopic change, conventional detection sensors cannot meet the accuracy requirements
In actual production, the punching and riveting dies are regularly removed manually and measured offline. Obviously, too frequent offline detection will inevitably affect the normal process and lead to unnecessary workload increases. However, if the wear cannot be found in time, it may lead to product quality defects

Abstract

The invention discloses a device for online wear detection of a self-piercing riveting gun mold. The device is characterized in that an image acquisition platform is provided for a riveting gun mold on a piercing riveting production line; an image acquisition device for obtaining a mold image is mounted on the image acquisition platform; an image acquisition signal of the image acquisition device is used as an output signal; a computer is used for analyzing the output signal so as to judge the wear degree of a mold. The device provided by the invention can timely monitor the wear state of the mold in an online detection manner, avoids product quality defects, also avoids tediousness brought by disassembly process and the influence on the normal process section, effectively improves the production efficiency, and ensures the product quality.

Description

technical field [0001] The invention relates to a self-piercing rivet die wear detection device, more specifically, an on-line detection device for self-pierce riveter die wear used in a body-in-white production line. Background technique [0002] The self-piercing riveting process is widely used in the modern body-in-white production line relying on its advanced nature. The self-piercing riveting process uses a self-piercing riveting gun to realize the connection. The self-piercing riveting gun includes a rivet and a punching riveting die, and the riveting gun is used to connect the rivet to the body-in-white panel; during the punching riveting process, the punching riveting die plays a supporting role ; After a certain number of times of punching and riveting, the punching riveting die will be worn out. In order not to affect the quality of riveting, it is necessary to replace the worn out punching riveting die in time. [0003] Since the wear of the riveting die is a mic...
