Description

Technical Field

[0001] The utility model relates to the technical field of power line production, in particular to a power line quality inspection and screening device. Background Art

[0002] The power cord is an electric wire that transmits electric current. Usually, the current is transmitted point to point. According to their use, power cords can be divided into AC power cords and DC power cords. Usually, AC power cords are wires that pass higher voltage alternating current, while DC cords basically pass lower voltage direct current. In order to ensure safe use, power cords need to be quality inspected during the production process, and those that fail the quality inspection need to be screened.

[0003] Chinese patent CN 219702725 U discloses a power line quality inspection and screening device, comprising a conveyor belt and a power line, wherein the power line is placed on the conveyor belt, a frame is installed on the conveyor belt, an ultrasonic flaw detector is installed on the frame, the ultrasonic flaw detector is connected to an ultrasonic probe through a cable, and the ultrasonic probe is installed on the frame. The beneficial effects of the utility model are as follows: the power line is placed on the conveyor belt for transportation, the ultrasonic flaw detector operates the ultrasonic probe through the cable to conduct a comprehensive quality inspection on the power line, and detects whether there is damage inside the power line. The power line that passes the quality inspection is transported from the left side of the conveyor belt through the blocking of a conical plate on the conveyor belt. When the quality inspection power line fails, the staff controls the servo motor to reverse, and when the power line enters the rotation range of the conical plate, the conical plate blocks the unqualified power line to the right side of the transmission belt for transportation, and the unqualified power line can be screened out.

[0004] In the above patent, the power cord to be inspected is placed in a placement slot on the conveyor belt, and there is no limiting structure for the power cord. The power cord actually produced cannot remain straight. Therefore, the power cord placed in the placement slot cannot remain straight until the ultrasonic probe is fully inspected, resulting in the quality inspection accuracy being affected. Therefore, the utility model proposes a power cord quality inspection and screening device to solve the shortcomings of the prior art. Utility Model Content
