[0002] In the use of military and aerospace communications, the performance of communication cables is very important, which is related to the service life, performance and maintenance cost of the equipment. Therefore, it is critical to control the size of each component of the connector. In the process of component size detection, the processing size accuracy of the parts must meet the design standard requirements. Only when the size of each component meets the design standard can the performance of the assembly be guaranteed. Any abnormality in the size of the part may lead to abnormal electrical performance of the component.

The optical fiber sensor 22 is arranged directly opposite to the material docking port 17 to detect whether there is material.

[0043] The material 9 transported in the flow channel 2 passes through the material receiving port 17 and enters the material trough 18, realizing rapid transfer and precise positioning of the material 9. The solenoid valve 42 connected to the material error cylinder 12 is controlled by the all-in-one controller 41, and the material error cylinder 12 is actuated to drive the material error rod 15 to slide along the slide groove to the position corresponding to the pushing mechanism.

[0047] The base 7 is also provided with an electric control box 40, and the electric control box 40 is provided with an all-in-one controller 41, and the all-in-one controller 41 controls the action of the material error mechanism, the material pushing mechanism and the material receiving mechanism. The all-in-one controller 41 satisfies both human-computer interaction and program control. The all-in-one controller 41 is connected to the direct vibration controller 10 and the electromagnetic valve 42 arranged on the side of the electric control box 40 through a time relay. The direct vibration controller 10 controls the action of the linear vibrator 1, and the electromagnetic valve 42 is connected to the material error cylinder 12, the material pushing cylinder 25, and the material receiving cylinder 32.

[0048] Working principle: Place the material 9 in the flow channel 2, turn on the direct vibration controller 10, start the linear vibrator 1, and all the materials 9 flow through the flow channel 2 to the material waiting position, that is, the material slot 18 of the material rod 15; press the start button 43 on the electric control box 40, the optical fiber sensor 22 senses the existence of the material 9, sends a signal to the integrated machine controller 41 through the optical fiber amplifier, and transmits a "material" signal to the system, and the material cylinder 12 drives the material rod 15 to move to the detection position, that is, the position facing the push cylinder 25; the visual inspection device performs size detection on the material 9, and at the same time sends a push signal to the push cylinder 25, and sends a "qualified" or "unqualified" detection result signal to the receiving cylinder 32. In addition, the display screen 49 will also display the test legend of the material 9 and the test results. After the receiving cylinder 32 receives the signal, if it is a qualified material, the receiving cylinder 32 moves the qualified receiving box to the bottom of the guide slot 29; if it is an unqualified material, the unqualified receiving box is moved to the bottom of the guide slot 29. The push cylinder 25 pushes the material 9 out, and the material 9 flows to the corresponding receiving box 31 through the material guide trough 29. The movement is repeated to realize the automatic size detection process of the material 9.

[0049] In order to be applicable to the rapid size detection of specific products, a carrier-type visual automatic detection system is specially developed. The system has relatively outstanding advantages in both cost and efficiency. The present invention uses the mutual cooperation of the integrated machine controller 41, the solenoid valve 42, the direct vibration controller 10 and the visual detection device; the solenoid valve 42 controls the action of the cylinder, the direct vibration controller 10 controls the action of the linear vibrator 1, the visual detection device realizes the size detection, and the integrated machine controller 41 controls the action of the entire detection system. The present invention can liberate manpower by setting up a linear vibrator 1 to assist in feeding, and does not require personnel to feed and take materials all the time. After the test is completed, qualified and unqualified materials can be taken out at one time. By setting up a wrong material mechanism, the rapid transfer of materials can be realized, and the positioning detection can be realized in conjunction with the visual detection device, which not only ensures efficiency, but also ensures that the detection accuracy is not affected by the inconsistency of the dynamic position of the material. By setting up the integrated machine controller 41 and the visual detection device, the repeatability of manual auxiliary detection is fully assigned to the machine, saving labor costs, while improving efficiency, optimizing the working environment, improving the efficiency of part size detection, and ensuring assembly quality and product performance.
