AI Technical Summary

Technical Problem

Conventional spot welding equipment requires multiple inspection devices to achieve efficient inspection, leading to increased equipment costs and space requirements, while existing methods fail to address continuous welding defects caused by the condition of the welding tip effectively.

Method used

The equipment employs a sampling inspection method where welding points are divided into groups, with one selected dot per group, and a single inspection device is used to inspect these points within a controlled time frame, ensuring no overlap and reducing the need for multiple devices.

Benefits of technology

This approach reduces equipment costs and space requirements by using a single inspection device while preventing defective products from being produced and improving inspection accuracy and reliability.

Abstract

To provide a spot welding facility that can be saved in facility cost and whose areas are small.SOLUTION: In a spot welding facility 20, two spot welding machines 22 and 31 are arranged while one inspection device 40 is arranged. A carrying apparatus 50 makes a selected striking point face an inspection element 43 to make the element execute sampling inspection. Only one inspection device 40 can execute the inspection completely, which can save facility costs and make areas of the facility smaller.SELECTED DRAWING: Figure 9
