[0005] (3) clear and clear inspection standards.

[0006] Inspection work is the key to good product quality. Through quality inspection of each link and each process in the production process, the enterprise ensures that unqualified raw materials are not put into production; unqualified semi-finished products are not flowed into the next process; unqualified products are not shipped. The product inspection system reports and feeds back the quality inspection information to the enterprise in time, provides basis for the enterprise to study and solve product quality problems, so as to continuously improve and improve product quality, and improve the economic benefit and social benefit of the enterprise.

[0040] The present invention provides a wire quality testing device in detail below with reference to embodiments and accompanying drawings.

[0041] like Figure 1 As shown, this invention proposes a conductor quality testing device, comprising a rotating angle measuring platform 1, characterized in that it further comprises: a rotating arm 2 for repeatedly bending the conductor 4 to be tested; a rotating arm connecting terminal 3 for fixing the conductor 4 to be tested and simultaneously contacting a conductive ring 12; a rotating arm intermediate terminal 5 connected to the rotating arm 2 for driving the rotating arm 2 to reciprocate; a stationary arm 6 for extending the conductor 4 to be tested and fixing a stationary arm connecting terminal 7, a spring force gauge 8, and a stationary arm end nut 9; the stationary arm connecting terminal 7 is used to connect and fix the conductor 4 to be tested, and simultaneously connects to the spring force gauge 8, and also connects to an auxiliary power supply. The A end of power source 13; spring force gauge 8; one end connected to the stationary arm connection terminal 7, and the other end connected to the tension adjustment screw 10, used to display the tension applied to the test lead 4; stationary arm end nut 9, used to fix the tension adjustment screw 10; tension adjustment screw 10 passes through the stationary arm end nut 9 and is used to adjust the tension applied to the test lead 4 by rotation; conductive ring connection terminal 11, connected to conductive ring 12, used to connect to the B end of auxiliary power source 13; conductive ring 12, connected to rotating arm connection terminal 3, used to power the test lead 4; servo motor 14, used to make the rotating arm 2 reciprocate.

[0042] like Figure 2 and Figure 3 As shown, the intermediate terminal 5 of the rotating arm includes a wire through hole 52 for the wire 4 to be passed through, so that the wire 4 to be tested forms a bending angle when the rotating arm 2 rotates; a temperature sensor 51 is placed inside the wire through hole 52 for measuring the temperature of the wire 4 to be tested; and a rotating arm connecting shaft 53 is connected to the A end of the servo motor 14 for driving the intermediate terminal 5 of the rotating arm to move.

[0043] Example 1:

[0044] like Figure 1 , Figure 3 So and Figure 5The A end of the servo motor 14 is connected to the rotating arm connecting shaft 53, and drives the rotating arm 2 to reciprocate, and the movement angle can be set in the range of -135° to 135°. Under the drive of the rotating arm 2, the measured wire 4 passing through the wire via hole 52 is repeatedly bent at the set bending angle. The number of reciprocating movements of the rotating arm 2, i.e. the number of bending of the measured wire 4, can be directly recorded by the controller of the servo motor 14.

[0045] The tension required to be set during the repeated bending of the measured wire 4 is set by rotating the tension adjusting screw 10, and the value of the tension is displayed by the spring dynamometer 8.

[0046] The B end of the auxiliary power supply 13, the conductive ring connecting terminal 11, the conductive ring 12, the rotating arm connecting terminal 3, the measured wire 4, the stationary arm connecting terminal 7, the A end of the auxiliary power supply 13 and the auxiliary power supply 13 can form a power supply closed loop. The auxiliary power supply 13 changes the power supply current, which can indirectly change the body temperature of the measured wire 4, and the temperature value can be measured by the temperature sensor 51.

[0047] During the repeated bending of the measured wire 4, the auxiliary power supply 13 detects the impedance change parameter in the power supply closed loop, judges the working condition and quality cracking degree of the measured wire 4, and when the power supply closed loop appears open circuit, the auxiliary power supply 13 cannot continue to provide current for the measured wire 4, and the power supply indicator light is turned off. At this time, it indicates that the measured wire 4 is broken, the controller of the servo motor 14 records the number of reciprocating movements, and the test will be completed.

[0048] The wire quality detection device of the present application can flexibly set the detection parameters, realize unified detection standard, automatically complete the wire quality detection, and realize the purpose of improving the wire quality detection capability. The system control is simple, flexible, low cost, and high safety, which greatly helps to reduce the labor intensity of the wire quality inspection personnel, enrich the inspection means, and unify and clarify the inspection standard.
