Description

Technical Field

[0001] This utility model belongs to the field of enameled wire technology, and in particular relates to a device for accurate detection of the continuity of the enameled wire coating. Background Technology

[0002] Continuity testing of the enamel film on enameled wire is a crucial step in ensuring wire quality, directly impacting its electrical performance and service life. Testing methods primarily include high-voltage corona discharge testing, pinhole testing, and optical testing. The high-voltage corona discharge testing method requires a high-voltage enamel film continuity tester.

[0003] In the existing technology, the winding structure of the testing instrument is relatively simple. The size of the winding wheel is fixed and it is not easy to disassemble. When using it, the sample line is directly wound up. After the test, the operator needs to manually unwind the wound sample line one coil at a time. The sample line is usually 30m long, which takes a lot of time to process.

[0004] Therefore, we propose a device for accurate detection of the continuity of the enameled wire coating. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the simple winding structure of testing instruments, the fixed size of the winding wheel that is not easy to disassemble, the direct winding of the sample wire during use, and the need for operators to manually unwind the wound sample wire one coil at a time after the test, which is time-consuming as the sample wire is usually 30m long. Therefore, this invention proposes a device for accurate detection of the continuity of the enameled wire coating.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for accurately detecting the continuity of enameled wire coating includes a testing instrument body. A control panel and a display screen are fixedly embedded on one side of the testing instrument body, and multiple conductive guide wheels are rotatably connected to one side of the testing instrument body.

[0008] The two sides of the test instrument body are respectively fixed with a wire feeding assembly and a wire take-up assembly. The wire feeding assembly and the wire take-up assembly have the same structure and are arranged symmetrically. The wire take-up assembly includes a mounting plate fixed to one side of the test instrument body. A movable seat is rotatably passed through one side of the mounting plate. The outer wall of the movable seat has a plurality of evenly distributed grooves. A sliding plate is slidably connected in the groove. The width of the sliding plate is less than the depth of the groove. A wire take-up groove is opened on one side of the sliding plate. A guide rod is fixed on one side of the sliding plate.

[0009] A drive mechanism is provided on one side of the mounting plate to provide drive for the movable seat;

[0010] The movable seat is equipped with an adjustment mechanism on one side, which is used to adjust the position of multiple slides simultaneously.

[0011] In one possible design, the drive mechanism includes a bracket fixed to one side of the mounting plate, a motor fixed to one side of the bracket, and the output shaft of the motor fixed to a movable seat.

[0012] In one possible design, the adjustment mechanism includes a turntable and multiple positioning slots, which are evenly distributed on one side of the movable seat. The turntable is rotatably connected to one side of the movable seat. Multiple guide slots are provided through one side of the turntable, and multiple guide rods pass through the multiple guide slots respectively. A positioning bolt is threaded through one side of the turntable, and one end of the positioning bolt is located in one of the positioning slots.

[0013] In one possible design, a fixing rod is fixed to the outer wall of the movable seat, and a pressure block is threadedly connected to the outer wall of the fixing rod.

[0014] In one possible design, one inner wall of the take-up groove is set as an outwardly convex arc.

[0015] In one possible design, two rubber blocks are fixed to one side of the skateboard.

[0016] In one possible design, a shield is fixed to one side of the mounting plate, and a heat dissipation vent is opened through one side of the shield, with the motor located inside the shield.

[0017] In this application, when in use, the spool with the sample wire wound around it is placed on the slide plate of the wire feeding assembly. The turntable is rotated, and under the guidance of the guide groove, the turntable drives the slide plate to extend outward, thereby limiting the spool. Then, the positioning bolt is rotated to enter the corresponding positioning groove, and one end of the sample wire is passed through the conductive guide wheel.

[0018] If the sample wire is to be wound up directly, wrap one end of the sample wire around the take-up groove once, then wrap the wire end around the fixed rod, rotate the pressure block to press the wire end, then start the motor to drive the movable seat to rotate, thereby driving the sample wire to unwind and rewind. Then use the testing instrument to test the sample wire. After the test is completed, the take-up assembly has finished winding up all the sample wire. At this time, rotate the positioning bolt to disengage from the positioning groove, then rotate the turntable in the opposite direction to completely retract the slide plate into the groove. At this time, the sample wire is in a loose state. Rotate the pressure block to contact and press the wire end, and then directly remove the sample wire from the movable seat.

[0019] If a spool is used to wind up the sample thread, place the spool on the slide plate of the take-up assembly, rotate the turntable, and under the guidance of the guide groove, the turntable drives the slide plate to extend outward, thereby limiting the spool. Then, wrap one end of the sample thread around the spool once, and then wrap the thread end around the fixed rod. Rotate the pressure block to tighten the thread end, and then start the motor to drive the movable seat to rotate, thereby driving the sample thread to unwind and wind up. Then, use a testing instrument to test the sample thread. After the test is completed, the spool has finished winding up all the sample thread. At this time, rotate the positioning bolt to disengage from the positioning groove, and then rotate the turntable in the opposite direction to completely retract the slide plate into the groove, contacting the support of the spool. Rotate the pressure block to contact the tightening of the thread end, and then directly remove the spool with the wound sample thread from the movable seat.

[0020] Beneficial effects: The enameled wire coating continuity precision detection device described in this utility model, through the setting of multiple structures such as slider, take-up groove and turntable, can facilitate the operator to quickly unload the wound sample wire, saving the operator's time and energy.

[0021] In this utility model, the enameled wire coating continuity precision detection device, through the setting of multiple structures such as slider, guide rod and turntable, can be supported by rolls of various specifications. The rolls can be used to unload the sample wire, and the rolls can also be installed on the take-up assembly for take-up, making it flexible and convenient to use.

[0022] This invention allows operators to quickly and easily unwind the wound sample line, saving them time and effort. It can be supported by various sizes of reels, which can be used to unwind the sample line or be mounted on a take-up assembly for winding. It is flexible and convenient to use.
