Intelligent projection welding subassembly gauge and detection method thereof

Abstract

The invention relates to an intelligent projection welding subassembly gauge and a detection method thereof, and belongs to the field of tools and devices for manufacturing a body in white of a vehicle. According to the invention, the technical solution includes: the intelligent projection welding subassembly gauge includes a detection mechanism, a controlling mechanism and an object carrying box. The detection mechanism includes a gauge rack. The two sides of the gauge rack are provided with product slideways. The product slideways are provided with a detection surface therebetween. The detection surface is provided with part sensors, a range sensor, reference blocks, and positioning pins. The bottom part of the detection surface is connected to a pneumatic element. A controlling box is arranged at the bottom part of the detection rack. According to the invention, the intelligent gauge can real-time monitor the information of a project welding product, such as the number of nuts, product size, and the number of products, etc., so as to prevent unqualified products from entering next step, and guarantees the quality of the projection welding subassembly products.

Description

technical field [0001] The invention belongs to the field of tooling equipment for automobile body-in-white manufacturing, and relates to the field of inspection tools for body-in-white in the field. More specifically, the present invention is an intelligent inspection tool for projection welding sub-assembly and its inspection method. Background technique [0002] Projection welding is a common welding process in the production process of body-in-white. Its main purpose is to weld stamping products and nuts or studs together through the strong current and high pressure of the projection welding machine to form sub-assemblies. Multiple sub-assemblies go through welding and other processes to finally form the body-in-white assembly. [0003] At present, the automotive industry has inspection tools for stamping parts and body-in-white assemblies, but there is no mature inspection tool for projection welding sub-assemblies. As a result, the quality of sub-assemblies after pro...

AI Technical Summary

Problems solved by technology

As a result, the quality of sub-assemblies after projection welding can only be judged by humans. For new employees with insufficient experience, if defective products are not detected in time, defective products such as missing welding and deformation will flow into the factory. The next process or body-in-white assembly will have a great impact and loss on the safety of customers, companies and users

And if it is required to completely detect defective products, employees need a lot of experience accumulation

In addition, for daily or monthly inventory, employees need to spend more time and manpower to inventory the projection welding products, and the accuracy of the inventory is difficult to guarantee
