Detailed Description
Hereinafter, specific embodiments of the present invention will be described in detail. Well-known structures or functions may not be described in detail in the following embodiments in order to avoid unnecessarily obscuring the details. Approximating language, as used herein in the following examples, may be applied to identify quantitative representations that could permissibly vary in number without resulting in a change in the basic function. Unless defined otherwise, technical and scientific terms used in the following examples have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
Example 1
A tool capable of automatically detecting neglected loading of a copper sleeve comprises a reflection-type photoelectric sensor 1, a correlation-type photoelectric sensor 2, a metal sensor 3, a detection platform 4, a turnover cylinder 5, a cylinder base 6, an electromagnetic valve, a relay, a programmable logic controller and an alarm, wherein the upper end of the detection platform 4 is respectively connected with a group of reflection-type photoelectric sensors 1 and a group of correlation-type photoelectric sensors 2, meanwhile, the upper end of the detection platform 4 is also connected with four groups of metal sensors 3, the lower end of the turnover cylinder 5 is fixedly connected to the cylinder base 6, the upper end of the turnover cylinder 5 is connected with the bottom end of the detection platform 4, and the electromagnetic valve is connected to a gas circuit of the turnover cylinder 5;
the reflection type photoelectric sensor 1 and the correlation type photoelectric sensor 2 are respectively and electrically connected with the relay, the correlation type photoelectric sensor 2 and the metal sensor 3 are respectively and communicatively connected with the programmable controller, and the programmable controller is respectively and communicatively connected with the electromagnetic valve and the alarm.
The electromagnetic valve, the relay and the programmable controller are respectively connected inside the control cabinet. The alarm is connected to the cylinder base 6. Still include the arm and the product that awaits measuring, the product centre gripping that awaits measuring in on the arm, the arm is located testing platform 4's top, the arm is in reflection-type photoelectric sensor 1's induction range, the product that awaits measuring is in correlation type photoelectric sensor 2's induction range. The two groups of overturning cylinders 5 are respectively connected to two sides of the bottom end of the detection platform 4.
The working principle of the technical scheme is as follows:
the power supply of the control cabinet is started, the sensors are electrified to stand by, the injection molding mechanical arm takes out four products from the mold and moves to the position above the detection platform 4, the products are placed on the detection platform 4, the correlation type photoelectric sensor 2 senses the products, and signals are output to the normally closed contacts of the relay. At the moment, the reflection-type photoelectric sensor 1 senses that the mechanical arm is above the detection platform 4, and starts to output a signal to the relay, the relay is closed, and the normally closed contact becomes the normally open contact. The output signal of the opposite-type photosensor 2 is cut off. When the manipulator puts the product well and leaves the detection platform 4, the reflection-type photoelectric sensor 1 cannot sense the manipulator, the output of a signal to the relay is stopped, the relay does not have a signal and does not attract, the normally closed contact is connected, and a sensing signal of the correlation-type photoelectric sensor 2 is transmitted to the programmable controller. The programmable controller receives the induction signal of the correlation photoelectric sensor 2, and the program synchronous operation delays for five seconds to output a signal to the alarm. And the alarm continues to give an alarm after five seconds. At the moment, the metal sensor 3 senses that the copper sleeve exists and starts working, and four paths of signals are output to the programmable controller. At this time, the programmable controller receives five signal inputs in total. And (3) program synchronous operation, wherein only when all five paths of signals are input effectively, the programmable controller outputs a path of ten-second holding signal to the electromagnetic valve, and simultaneously, the programmable controller logically controls and cancels the work of the alarm, so that the alarm cannot give an alarm after five seconds. The electromagnetic valve 5 starts working for ten seconds after receiving the signal, drives the cylinder base 6 to overturn, slides the product onto the conveying belt, and conveys the product to the next station. And the cylinder base 6 finishes working for ten seconds and returns to the original point to stand by. Waiting for the product to work circularly.
When the copper bush neglected loading product appears, different feedback results appear when the operation is carried out to the step 5, and the following steps are introduced from the fifth step:
the metal sensor 3 senses the existence of the copper bush to start working and outputs a signal to the programmable controller. Because of the neglected installation of the copper sleeve, the output signal cannot be a four-path signal. At this time, signals received by the programmable controller are lacked, and five paths of signals cannot be formed. And (4) program synchronous operation is carried out, when the received signals do not reach five paths, the program controller can not output signals to the electromagnetic valve, the alarm can not be cancelled through logic control, and continuous alarm is started after the alarm is used for five seconds. The electromagnetic valve can not work because the electromagnetic valve does not receive a signal, the product is kept on the detection platform 4, the alarm continuously gives an alarm to remind an operator of the occurrence of defective products, and the alarm is relieved after the defective products on the detection platform 4 are taken away. Waiting for the product to work circularly.
