Detailed Description
In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the utility model only and are not intended to limit the scope of the utility model.
As shown in fig. 1, the present invention includes: a photoelectric induction sensor, a position sensor, an electromagnetic relay and a control center,
the photoelectric induction sensor and the position sensor are connected with an input signal to the PLC industrial personal computer, the PLC industrial personal computer outputs a signal to the LED lamp to visually judge the loading state, the LED lamp judging result passes through the electromagnetic relay, and the electromagnetic relay is linked with the control center.
In this embodiment, the control center preferably includes database technology to collect and create a database of the defective samples.
In this embodiment, the control center is preferably connected to an external history storage base station, and the history storage base station includes visual inspection history information therein.
In this embodiment, the position sensor is preferably connected to a robot-driven camera detection device, which can move in multiple directions for detection.
In the present embodiment, the LED lamp is preferably controlled by an independent light source control system.
Preferably in this implementation, LED lamp is inside to be equipped with a plurality of lamp pearls, and every lamp pearl colour is different.
The working principle is as follows:
when a product is loaded, the position sensor senses the material loading state, and the photoelectric sensing sensor confirms and judges again, and triggers the PLC industrial personal computer to output a signal to the LED lamp to visually judge the loading state; and the judgment result is linked with the control center piece through an electromagnetic relay, and if the abnormality occurs, the device alarm prompt is triggered and the device is forced to stop.
The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
