With the continuous development of industrial technology, the performance requirements for enameled wire are becoming increasingly stringent, making the testing of enameled wire performance particularly important.

[0019] This utility model provides a device for testing the performance of enameled wire, including a frame 101 and a testing unit. The testing unit includes a side frame 102, a first stepper motor 103, a wire feeding reel 104, a bidirectional screw 105, two clamping frames 106, a wire feeding roller 107, a second stepper motor 108, a laser diameter gauge 109, an eddy current thickness gauge 110, a fixing rod 111, a tension sensor 112, a controller 113, a wire roller 114, and a take-up mechanism. The take-up mechanism includes a mounting plate 115, a take-up roller 116, and a clamping component. The clamping component includes a mounting base 117, a pressure plate 118, and fixing bolts 119. The wire feeding reel 104 has a sliding groove 120, and the mounting base 117 has a wire insertion groove 121.

[0020] The detection unit is connected to the frame 101; the side frame 102 is fixedly connected to the frame 101 and located above the frame 101; the first stepper motor 103 is fixedly connected to the side frame 102 and located on one side of the side frame 102; the pay-off reel 104 is fixedly connected to the first stepper motor 103 and located at the output end of the first stepper motor 103; the pay-off reel 104 has a sliding groove 120, which slides in cooperation with the two clamping frames 106; the bidirectional screw 105 is connected to the pay-off reel. 104 is rotatably connected and located on the inner side wall of the slide groove 120, and the bidirectional screw 105 is threadedly engaged with the two clamping frames 106 respectively. The wire feeding roller 107 is disposed on the outer side wall of the two clamping frames 106. The second stepper motor 108 is fixedly connected to the side frame 102 and is located on one side of the side frame 102. The wire take-up mechanism is disposed at the output end of the second stepper motor 108. The laser diameter gauge 109 is disposed on one side of the side frame 102. The eddy current thickness gauge 110 is disposed above the frame 101.

[0021] In this embodiment, the enameled wire is placed on the pay-off roller 107, and its end is fixed by the take-up mechanism. The position of the two clamping frames 106 in the groove 120 can be adjusted by rotating the bidirectional screw 105 to accommodate pay-off rollers 107 of different specifications. During operation, the first stepper motor 103 drives the pay-off reel 104 to rotate, causing the pay-off roller 107 to release the enameled wire. At the same time, the second stepper motor 108 drives the take-up mechanism to wind up the enameled wire. During this process, the laser diameter gauge 109 detects the diameter of the enameled wire, and the eddy current thickness gauge 110 detects the coating thickness of the enameled wire. This completes the online monitoring of the dimensions and coating thickness of the enameled wire during the pay-off and take-up processes. By detecting the enameled wire in this way, the accuracy of the detection data can be effectively improved, the use of subsequent detection data can be facilitated, and the detection workload of the staff can be reduced.

[0022] The laser diameter gauge 109 is an LSG-1005 model, which can measure the outer diameter of enameled wire non-contactly with a measurement accuracy of up to 0.001 mm. It scans the enameled wire with a laser beam to obtain the diameter data of the enameled wire in real time.

[0023] The eddy current thickness gauge 110 is an ED400 model, used to detect the thickness of the insulation layer of enameled wire. Its probe is kept at a certain distance from the enameled wire, and the thickness of the insulation layer is measured by electromagnetic induction. The measurement range is 0-5mm and the accuracy is 0.01mm.

[0024] Furthermore, the fixing rod 111 is fixedly connected to the side frame 102 and is located on one side of the side frame 102, and the guide roller 114 is rotatably connected to the fixing rod 111 and is located at one end of the fixing rod 111.

[0025] In this embodiment, the fixed rod 111 and the guide roller 114 cooperate to guide the enameled wire to move along a preset path, thereby completing the unwinding and rewinding of the enameled wire.

[0027] In this embodiment, the tension sensor 112 monitors the tension changes of the enameled wire in real time during the take-up and unwinding stages and feeds the data back to the control terminal in real time. The control terminal dynamically adjusts the rotation speed of the first stepper motor 103 and the second stepper motor 108 based on the data to ensure the stability of the enameled wire tension throughout the detection process and avoid the impact of tension fluctuations on detection accuracy. The controller 113 is used to start and stop the first stepper motor 103, the second stepper motor 108, and the tension sensor 112.

[0028] The tension sensor 112 is a BLHNOBELKIS-8-50KN type tension sensor.

[0029] The controller 113 adopts the Siemens S7-200SMART series and is responsible for controlling the operation of various mechanisms of the equipment to realize the automated detection process. In particular, after receiving the tension data transmitted by the tension sensor 112 in the wire feeding and take-up mechanism, it can react quickly and send adjustment commands to the first stepper motor 103 and the second stepper motor 108.

[0030] Furthermore, the mounting plate 115 is fixedly connected to the second stepper motor 108 and is located at the output end of the second stepper motor 108. The take-up roller 116 is detachably connected to the mounting plate 115 and is located on one side of the mounting plate 115. The clamping member is disposed on the outer side wall of the take-up roller 116.

[0031] In this embodiment, the mounting plate 115 is used to fix to the output end of the second stepper motor 108, the take-up roller 116 is fixed with bolts to realize the detachability of the take-up roller 116, and the clamping member is used to fix the end of the enameled wire.

[0032] Furthermore, the mounting base 117 is fixedly connected to the take-up roller 116 and is located on the outer side wall of the take-up roller 116. The pressure plate 118 is disposed on the inner side wall of the mounting base 117. The fixing bolt 119 is threadedly connected to the pressure plate 118 and the mounting base 117 in sequence. The mounting base 117 has a wire insertion groove 121.

[0033] In this embodiment, the end of the enameled wire is inserted into the insertion slot 121, the pressure plate 118 is snapped down, and then the fixing bolt 119 is used to fix it, thereby fixing the end of the enameled wire. The structure is simple and easy for workers to operate and use.
