Taking a steel reinforcement cage as an example, it is necessary to process threads at least at one end of the main reinforcement of the steel reinforcement cage to meet the installation requirements of the steel reinforcement cage. Since the usage amount of steel reinforcement cages is large, realizing the batch production of steel reinforcement cages is the future development direction. Therefore, improving the detection efficiency of the processed threads on the main reinforcement of the steel reinforcement cage is a technical problem that needs to be urgently solved by those skilled in the art.

[0084] It should be noted that the number of the information collection units 4 included in the thread detection device 100 of this application is not specifically limited. In specific implementation, the number of the information collection units 4 can be selectively one, two, three, or more than four.
