Three-core power line visual deconcentrating system detected by optical fiber sensor

Abstract

A three-core power line visual deconcentrating system detected by an optical fiber sensor comprises a bottom plate, a rotating device, a line clamping device, a visual deconcentrator and a controller, wherein the rotating device, the line clamping device, the visual deconcentrator and the controller are installed on the bottom plate. The line clamping device is fixedly installed on the rotating device. The rotating device can drive the line clamping device to rotate. The rotating device comprises a driving motor for driving the line clamping device to rotate. An installation frame for installation of the visual deconcentrator is further arranged on the bottom plate, is movably installed on the bottom plate and can slide forward and backward relative to the line clamping device. The visual deconcentrator comprises an RGB color sensor which is electrically connected with the controller through an optical fiber. The RGB color senor comprises an RGB three-color LED light source with a built-in amplifier and a photosensitive element for receiving reflected light rays. The RGB color sensor is arranged over the portion, clamped by the line clamping device, of a power line. The three-core power line visual deconcentrating system detected by the optical fiber sensor is simple in structure, accurate and reliable in sampling and convenient to operate.

Description

technical field [0001] The invention relates to the field of electric wire processing, in particular to a visual branching system for a three-core power cord detected by an optical fiber sensor. Background technique [0002] In the automatic production process of the three-core power cord, it is necessary to visually distinguish the polarity (L pole, N pole, T pole) of the three-core power cord. Skeleton assembly to ensure that the production of power plug wires complies with international standards. [0003] However, the current production process of the three-core power plug wire is to manually strip the sheath wire and the insulated wire, and use human eyes to distinguish the polarity of the three wires according to the different colors of the three wires in the power cord, and to distinguish the polarity of the power supply. Wires carry corresponding riveted terminal blades. Corresponding to the polarity riveted terminal inserts also need to manually distinguish the po...

Problems solved by technology

This kind of human eyes distinguishes the polarity of the power cord, and correspondingly operates the riveting and mounting frame, which has the disadvantages of visual fatigue, paralysis errors, and low efficiency. , and the labor intensity of the workers is high, and more importantly, once the operator does not grasp the angle of rotation during the wiring process, it is easy to connect the wrong line, resulting in product scrap

[0004] In order to solve the above problems, the applicant provided a three-core power line visual branching device and its use method in the patent CN201310623009. The picture information is sent to the controller, and the controller compares it with the standard image in it, so as to judge whether the position of the power core wire is correct, so as to control the driving motor to drive the clamping device to rotate, and realize its automatic identification and change of the power core wire. Although it solves the problem of traditional manual identification of the core wire position to a large extent, because the CCD camera is affected by the industrial environment during the shooting process, such as: vibration during processing, and vibration generated during production Dust, etc. will cause the pictures taken by it to be unclear, making it difficult to compare and analyze the controller or cause analysis errors, which will affect the wiring errors of the power line; Affecting the brightness of its light, it is usually necessary to set up LED lights for supplementary light, which not only requires the installation of LED lights, but also requires wiring, which makes the mechanical structure and circuit structure more complex, not only high in manufacturing costs, but also easy to install. There is a circuit failure

[0005] From the perspective of the production process of the three-core power plug wire, after the power cord is visually separated, it is usually necessary to rivet the corresponding terminal inserts on the core wires of different poles. In the three-core power line visual branching device and its use method provided in the patent CN201310623009.3, when the rotating device drives the power line to rotate to a suitable position, the fish clip line device installed on the installation frame of the CCD camera is in the vertical The direction overlaps, which causes inconvenience to the mechanical riveting of the core wires, and easily leads to changes in the relative positions of the three core wires of the three-wire power cord, causing errors in core wire riveting, and resulting in the scrapping of the final product
