Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a detection device with a proximity switch protection function and a drive system with the detection device. Background Art

[0002] A proximity sensor, also known as a proximity switch, is a device that has the ability to sense the proximity of an object. It uses the sensitive characteristics of a displacement sensor to identify the approaching object and output a corresponding switch signal.

[0003] Since the proximity sensor is a device that has the ability to sense the approach of an object, its corresponding detection object is a movable object. During normal use, the detection object of the proximity sensor will move into the detection range of the proximity sensor, but still maintain a certain distance from the proximity sensor to prevent the detection object from damaging the proximity sensor. However, during use, special circumstances may occur, such as the movement trajectory of the detection object deviating from the track or the detection object getting stuck with other workpieces. At this time, when the detection object is moving, the detection object or the workpiece stuck on the detection object will damage the proximity sensor. At the same time, there are other safety hazards, which will cause economic losses to the company. Utility Model Content
