Abstract

The invention provides a belt monitoring system for a carrying device, the belt monitoring system comprises a belt and a sensing module. Wherein, a belt comprises a first signal line, a second signal line, and a connecting circuit. The first signal line is embedded at one side edge adjacent to the belt, the second signal line is embedded at the other side edge adjacent to the belt. The connecting circuit is disposed at one end of the belt, and connected between the first signal line and the second signal line, the first signal line, the connecting circuit, and the second signal line form a loop. The sensing module is disposed at the other end of belt and is respectively connected to the first signal line and the second signal line, the sensing module is used to sense whether the loop is off. The belt monitoring system in the invention is advantageous in that, sensing is performed via various singlas, and real-time monitoring of whether crack happens at the two side edges of the belt is performed, therefore, discovery in advance of complete crack of the belt is made, and necessary repair is performed.

Description

technical field

[0001] The present invention relates to a monitoring system, and in particular to a detection system for monitoring belt breakage. Background technique

[0002] In modern industrial society, automatic control system gradually replaces manpower and becomes the key to improve production efficiency. In particular, the advanced semiconductor manufacturing process has introduced a large number of automated equipment to perform various precision manufacturing steps to reduce costs and human errors.

[0003] For example, in a semiconductor factory, it is common to see a grinder table for grinding wafers, a robotic arm for grabbing wafers, and conveying equipment for transferring wafers or glass substrates, etc. Among the above-mentioned equipment, belt structures are often seen as power transmission or suspension of heavy objects.

[0004] Taking the existing suspended conveying equipment as an example, it usually includes a lifting belt connected with a driving m...
