Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to an electrode type enameled wire detection device. Background Art

[0002] At present, the known online detection device for enameled wire (electrode / detection head) is a clamping device composed of two V-shaped thin sheets with a thickness of about 1 mm and offset in opposite directions. When detecting the enameled wire passing quickly, since the contact area between the enameled wire and the detection sheet is only about 1 mm and they are offset and clamped in opposite directions, each detection sheet only wraps nearly half of the circumference of the enameled wire passing through, and the other half of the circumference is wrapped by another detection sheet located above / below it. During operation, this device will have an obvious clamping effect on the enameled wire passing through, and can only be used for large-sized, thick-film enameled wires produced by mold-type enameling machines; it cannot be used for enameled wires with thin paint films and small specifications produced by felt-type enameling machines, as the opposing clamping pressure of the two detection sheets will damage or even break the enameled wires with thin paint films and small specifications passing through; at the same time, the entire detection head structure is bulky and about 4 cm wide, and cannot be installed on narrow felt machine lines with a line spacing of only about 3 cm; in addition, the manufacturing cost is high. It can be seen that the existing online detection device for enameled wires has the following shortcomings: ① For the enameled wires passing through, especially for the enameled wires with thin paint film and small specifications produced by the felt type enameling machine, the enameled wires passing through will be damaged or even broken due to the opposite clamping effect of the detection piece; ② Since the thickness of the detection piece is only about 1mm, the contact surface between the enameled wire and the detection piece is also only about 1mm. During use, the contact time between the enameled wire and the detection piece when it passes through it quickly is extremely short, and the two detection pieces are of staggered clamping type, not directly symmetrically wrapped, resulting in insufficient detection when the enameled wire passes through it, which is prone to missed detection; ③ It cannot simultaneously meet the requirements of detecting enameled wires of different specifications, sizes and shapes (round wires, flat wires); ④ The entire detection head structure is bulky and has a width of about 4cm, which cannot be installed on the narrow felt machine line with a line spacing of only about 3cm; ⑤ The manufacturing cost is high.

[0003] In the Chinese invention patent application No.: 201410479985.0, an enameled wire detection device is disclosed, which includes a base and a detection head mounted on the base, and the detection head includes a flexible electrode for detecting the enameled wire. According to the enameled wire detection device of the invention, on the one hand, the contact area between the enameled wire and the flexible electrode is increased, which is convenient for comprehensively detecting pinholes on the paint film of the enameled wire, and on the other hand, the friction between the enameled wire and the flexible electrode can be reduced to avoid the electrode from damaging the enameled wire during the detection process.

[0004] Once the flexible electrode in the above-mentioned prior art is fixed, the size of the detection slot cannot be fine-tuned, so it cannot adapt to enameled wires of different diameters. In addition, the flexible electrode is fixed by pressing, and the pressing is tightened by bolts. Both hooks need to tighten the corresponding bolts, and tools are also required, which is time-consuming and labor-intensive, affecting efficiency.

A knob 7 is provided at the front end of the two-way screw rod 17, and the knob 7 is located on the front outer side of the base 1. A hanging groove 9 adapted to the hook 4 is provided on the top of the support frame 5. Through the mutual cooperation of the set knob 7, the support frame 5, the two-way screw rod 17, the moving block 18, the connecting block 20, and the push-pull connecting rod 21, it is convenient to fine-tune the distance between the two support frames 5, thereby realizing the adjustment of the inner cavity size of the detection slot 3 on the flexible electrode 2, and then it can adapt to the passage of enameled wires of different diameters, thereby increasing adaptability.

[0028] Through holes 11 are symmetrically provided at the front and rear ends of the lower end of the support frame 5, and guide rods 6 are symmetrically provided at the front and rear ends of the inner cavity of the groove 22.
