Indirect detection device

Abstract

The invention discloses an indirect detection device. The indirect detection device includes a base, a detector and a sensing body; by utilizing a characteristic that a detecting shaft moves up and down after being in contact with a component, feedback is sent to a sensor in the device, and therefore whether or not the detecting shaft is moving is determined, so that the existence of the componentcan be indirectly determined. The indirect detection device is applied in an automobile welding process; in an automated welding production line, a sensor is used for conducting detection of variouscomplicated components, the operation is convenient and fast, and the efficiency of automobile technological manufacturing is greatly improved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a component detection device. Background technique [0002] At present, the types of parts on the welding production line are mostly resin parts and metal parts. If you want to detect branch parts on the production line, you need to use a photoelectric sensor. If you need to detect metal parts, you need to use a proximity sensor. According to the difference between the size of the parts and the effective sensing distance of the sensor, it is also necessary to choose photoelectric sensors or proximity sensors of different sizes and sizes. It is necessary to use so many types of sensors on the same fixture, which is very difficult for production and maintenance. come with considerable difficulty.

[0003] In the field of automobile manufacturing, the detection of different parts requires the use of different types of sensors. According to the inherent performance of traditional sensors, the sensor can only detect within a certain distance from the sensor detection surface.

However, when the active range of the part is larger than the detection range of the traditional sensor, it will cause the wrong output of the sensor, so that the detection and sensing device must be frequently modified, resulting in a complex detection and sensing device and a low detection success rate.
