AI Technical Summary

Technical Problem

When assembling standard sections and racks of existing construction hoists, the dimensional differences lead to a high installation error rate, making it difficult to achieve accurate multi-dimensional verification, which increases the processing rework rate and cost.

Method used

By employing end-verification and multi-dimensional verification assemblies, a geared motor drives a rotating frame and an electric cylinder to push the support bar. Combined with positioning distance and proximity sensors, the rack and pinion are precisely aligned at the ends and middle of the standard section. The controller coordinates the actions for automated assembly line operation.

Benefits of technology

It significantly reduced the error rate of installation and assembly, reduced the rework rate, lowered the processing cost of machine tool assembly, and improved the consistency and efficiency of installation and assembly.
