Description

Technical Field

[0001] The invention relates to the technical field of detection devices, and in particular to an enameled stranded wire detection device. Background Art

[0002] Enameled wire is a main type of winding wire, consisting of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked multiple times. The enameled stranded wire is made by twisting the enameled single wire around the strand axis at equal angular velocity and moving the strand forward at a uniform speed. Copper and aluminum wires can be twisted into conductor cores of various cross-sections and different types of wires and cables. The enameled stranded wire is a wire in which multiple strands of enameled wire are twisted together in a clockwise or counterclockwise direction, usually in a spiral shape.

[0003] When the current enameled stranded wire detection device detects the enameled stranded wire, it uses an optical detector to detect the appearance of the enameled stranded wire to check whether the appearance of the enameled stranded wire is damaged, discolored or other abnormal conditions. During the detection, the detection personnel align different sections of the enameled stranded wire with the detection points of the optical detector for detection. Since the enameled stranded wire is soft in texture and easy to bend, some enameled stranded wires are not easy to align with the detection points of the optical detector and are easy to be out of the detection range of the optical detector. In addition, there will usually be errors when the detection personnel align different sections of the enameled stranded wire with the detection points of the optical detector, and calibration is required to ensure the accuracy of the detection. There is also the option of using a clamp to ensure that the enameled stranded wire is in a straight line, but when replacing different sections of the enameled stranded wire, it is necessary to first loosen the clamp and then clamp it again after replacing the sections of the enameled stranded wire, which greatly reduces the detection efficiency and the detection cost required in the production quality inspection stage is relatively high. Summary of the invention

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0028] See also Figures 1 to 4 The present invention provides a technical solution: an enameled stranded wire detection device, used for detecting an enameled stranded wire, wherein the enameled stranded wire is a wire in which multiple enameled wires are twisted together along a clockwise or counterclockwise rotation, which is a known technology in the prior art. For any enameled wire, it is in a spiral shape, so the enameled stranded wire has a corresponding number of spiral-shaped gaps X;

[0029] The enameled stranded wire detection device comprises a winding mechanism 10, a detection mechanism 30 and two wire fixing mechanisms 20;

[0030] The winding mechanism 10 is used to wind up the enameled stranded wire after pulling after inspection, and the two wire fixing mechanisms 20 and the winding mechanism 10 are sequentially arranged along the first direction;

[0031] The wire fixing mechanism 20 comprises a mounting ring body 201 and a wire fixing ring body 202. The wire fixing ring body 202 is rotatably connected in the mounting ring body 201. The inner ring of the wire fixing ring body 202 is provided with a clamping ball 203 corresponding to the number of strands of the enameled stranded wire. The wire fixing ring body 202 is sleeved on the outside of the enameled stranded wire and the clamping ball 203 is arranged in the wire fixing ring body 202 corresponding to the adjacent enameled wire seams on the enameled stranded wire.

[0032] The detection end of the detection mechanism 30 is located above the two wire fixing mechanisms 20 and is used to detect the enameled stranded wire located between the two wire fixing mechanisms 20;

[0033] The winding mechanism 10 is used to wind up the enameled stranded wire after the inspection. The traction force generated by the winding up causes the enameled stranded wire section between the two wire fixing mechanisms 20 to be changed into other enameled stranded wire sections. That is, the enameled stranded wire originally in the two wire fixing mechanisms 20 is the first section. Due to the traction generated by the winding up of the winding mechanism 10, the enameled stranded wire in the first section is moved to the winding mechanism 10, so that the enameled stranded wire originally located at the initial end portion is moved to between the two wire fixing mechanisms 20. When the winding mechanism 10 switches the position of the enameled stranded wire section, the enameled stranded wire section 20 is changed into other enameled stranded wire sections. The wire passes through a wire fixing mechanism 20, a detection mechanism 30, another wire fixing mechanism 20 from the initial end (such as structures such as an unwinding drum and a raw material shaft 602) in sequence, and is finally wound on the winding mechanism 10. In the above process, for the wire fixing mechanism 20, before or after the detection mechanism 30 performs detection, no adjustment is required (such as loosening the auxiliary fixation of the enameled stranded wire by the two wire fixing mechanisms 20, and then fixing the enameled stranded wire after the position is switched. The wire fixing mechanism 20 in this embodiment does not need to be adjusted in a similar manner). The specific analysis is as follows;

[0034] Through the connection between the mounting ring body 201 and the wire fixing ring body 202, the wire fixing ring body 202 can rotate within the mounting ring body 201, and the inner ring of the wire fixing ring body 202 matches the diameter of the enameled stranded wire, and a certain gap is left to provide a necessary position for the clamping ball 203, and corresponding clamping balls 203 are arranged in the gap (the number of clamping balls 203 corresponds to the number of gaps X in the enameled stranded wire). It can be understood that the clamping ball 203 fills the above-mentioned gap, and when the gap X moves along the first direction, its angle in the wire fixing mechanism 20 changes, and the corresponding clamping ball 203 is correspondingly pushed by the gap X to a corresponding angle. Therefore, when the enameled stranded wire moves along the first direction, the clamping ball 203 assists the enameled stranded wire to maintain a straight line between the two wire fixing mechanisms 20, ensuring that the enameled stranded wire will not appear arc-shaped or offset between the two wire fixing mechanisms 20, and the outer surface of the enameled stranded wire passes through the inner ring of the wire fixing ring body 202, and the clamping ball 203 is in contact with the enameled stranded wire. The gaps between the enameled wires of the stranded wire are in contact and connected, that is, they are pressed against the gaps between the enameled wires. When the enameled wires are pulled to move along the first direction, the clamping ball 203 assists the enameled wires to maintain a straight line, so as to prevent the enameled wires between the two fixed wire ring bodies 202 from being offset compared with the position of the previous enameled wires. At this time, since the clamping ball 203 is pressed against the gaps between the enameled wires, the enameled wires are in a straightened state. At the same time, the clamping ball 203 will not damage the paint film on the enameled wires. 3 cooperates with the wire fixing ring body 202 to produce a certain resistance to the movement of the enameled stranded wire, causing the enameled stranded wire to be straightened, but will not damage the paint film of the enameled stranded wire, does not affect subsequent use, and does not need to be frequently clamped and loosened like a clamp, which is troublesome to operate. If the clamp is not loosened, it is easy to scratch the paint film on the enameled stranded wire. By rotating the wire fixing ring body 202 in cooperation with the texture of the enameled stranded wire, the clamping ball 203 moves on the texture of the enameled stranded wire, thereby avoiding the situation of damaging the paint film on the enameled stranded wire;

[0035] The enameled stranded wire is a wire in which multiple strands of enameled wire are twisted together in a clockwise or counterclockwise direction. It is a known technology and is usually in a spiral shape.

[0036] Through the setting of the detection mechanism 30, the detection mechanism 30 is a known technology, and can be a camera 301 with a visual detection module to check whether there is damage, discoloration or other abnormalities on the appearance of the enameled stranded wire;

[0037] The detection mechanism 30 can also be used to perform non-destructive testing on the enameled stranded wire by X-ray scanning in conjunction with a ray receiving terminal to detect the internal structure and defects of the enameled stranded wire, which are all existing well-known technologies and are only cited here. When performing X-ray scanning on the enameled stranded wire, a light shielding shell is put on the outside of the wire fixing mechanism 20, which is not shown in the figure, and is a conventional technical means during operation;

[0038] Since the enameled stranded wire is straightened by the two wire fixing mechanisms 20, it is convenient for the detection mechanism 30 to capture the position of the enameled stranded wire, thereby avoiding detection errors caused by accidental deviation from the detection range or wrinkles in the enameled stranded wire due to failure to straighten the wire.

[0039] In this embodiment, as a preferred solution, the fixed line ring body 202 includes a swivel ring 2021 and a replacement ring 2022. The side of the swivel ring 2021 is detachably connected to the replacement ring 2022 through a groove. The swivel ring 2021 is rotatably connected in the installation ring body 201, and the clamping ball 203 is rotatably connected to the inner ring of the replacement ring 2022.

[0040] By connecting the rotating ring 2021 with the replacement ring 2022, the replacement ring 2022 can be replaced. There can be multiple replacement rings 2022 with different inner ring diameters. The replacement ring 2022 with a suitable inner ring diameter can be selected according to the diameter of the clamped enameled stranded wire. At the same time, the number and setting angles of the clamping balls 203 are preset angles to match the standard wire strand spacing of the enameled stranded wire. When the spacing of the enameled stranded wire is unequal, the more flexible connection of the clamping balls 203 can also play a compensatory role. The surface of the clamping balls 203 is in close contact with the enameled wire seam on the enameled stranded wire, and the clamping balls 203 can rotate inside the replacement ring 2022 to avoid rubbing off the paint film on the enameled stranded wire.

[0041] In this embodiment, as a preferred solution, the mounting ring body 201 includes a fixing ring 2011, a base 2012 and a cover 2013. One end of the base 2012 is fixedly mounted on the support surface, the fixing ring 2011 is fixedly connected to the other end of the base 2012, the inner ring of the fixing ring 2011 is rotatably connected to the outer surface of the slewing ring 2021, the cover 2013 is threadedly connected to the outer surface of the fixing ring 2011, and the cover 2013 is at least partially in contact with the side surface of the replacement ring 2022.

[0042] Through the connection between the fixed ring 2011 and the slewing ring 2021, the slewing ring 2021 can be slewed inside the fixed ring 2011. Through the function of the base 2012, the fixed ring 2011 can be supported. Through the function of the cover 2013, the replacement ring 2022 is limited to avoid the replacement ring 2022 from being separated from the slewing ring 2021 due to the traction of the enameled stranded wire. Through the connection between the cover 2013 and the fixed ring 2011, the cover 2013 can be installed or removed. By installing the cover 2013, the replacement ring 2022 is limited. By removing the cover 2013, the replacement ring 2022 can be removed. The cover 213 does not affect the rotation of the slewing ring 2021.

[0043] When in use, first select a replacement ring 2022 with a suitable inner diameter according to the diameter of the enameled stranded wire, and install the replacement ring 2022 on the rotating ring 2021. The rotating ring 2021 is provided with a corresponding slot, and the replacement ring 2022 is provided with a corresponding block. The block is inserted into the slot, and then the replacement ring 2022 is locked by the cover 2013 to prevent the replacement ring 2022 from falling off. One end of the enameled stranded wire extends out of the first replacement ring 2022 first, so that the seam ball 203 is located between the enameled wire seams of the enameled stranded wire, and then passes through another replacement ring 2022, and then connected to the winding mechanism 10, and the tested enameled stranded wire is wound up by the winding mechanism 10.

[0044] In this embodiment, as a preferred solution, the detection mechanism 30 also includes a camera 301, an adjustment frame 302 and an image processing module. The camera 301 is fixedly connected to the telescopic end of the adjustment frame 302 and is located above the two fixed line mechanisms 20. The output end of the camera 301 is electrically connected to the input end of the image processing module.

[0045] The camera 301 and the image processing module are used to detect the appearance of the enameled stranded wire to detect whether there are any abnormal conditions such as damage or discoloration. The height position of the camera 301 can be adjusted by setting the adjustment frame 302 to facilitate focus adjustment.

[0046] In this embodiment, as a preferred solution, the detection mechanism 30 also includes an insulation resistance meter, the two ends of the enameled stranded wire are respectively connected to the positive electrode and the negative electrode of the power supply, the mounting ring body 201, the fixed wire ring body 202 and the card seam ball 203 are all made of conductive materials, one of the input ends of the insulation resistance meter is electrically connected to the mounting ring body 201, and the other input end of the insulation resistance meter is connected to the positive electrode or the negative electrode of the power supply, and the fixed end of the mounting ring body 201 is grounded;

[0047] A certain voltage is applied to the enameled stranded wire, and the insulation resistance meter is used to detect whether the insulation strength of the enameled stranded wire meets the requirements. The wire fixing ring body 202 and the clamping ball 203 are in contact with the enameled stranded wire and fully fit with the outer surface of the enameled stranded wire. When the paint film on the outer surface of the enameled stranded wire is damaged or the insulation strength is poor, the current on the enameled stranded wire can be received, and then the insulation resistance meter can be used to achieve detection. At the same time, in the process of pulling the enameled stranded wire to switch different sections of the enameled stranded wire, the clamping ball 203 and the wire fixing ring body 202 are also kept in close contact with the enameled stranded wire, which can avoid omissions and failures to detect. At the same time, it will not cause interference and influence when switching different sections of the enameled stranded wire according to detection needs. The insulation strength of the enameled stranded wire can be carefully detected without stopping the operation of changing the position of the enameled stranded wire, and there is no need for the two conductive parts of the insulation resistance meter to specifically clamp a certain section of the enameled stranded wire, resulting in partial section of the enameled stranded wire being missed, which is also more efficient.

[0049] In this embodiment, as a preferred solution, the winding mechanism 10 includes a supporting cylinder 101 and a winding member 102. The supporting cylinder 101 and the winding member 102 are arranged on the supporting plate 601 in sequence along the second direction. The rotating end of the winding member 102 is slidably connected to the surface of the enameled stranded wire, and is used to wind the enameled stranded wire around the supporting cylinder 101.

[0050] In this embodiment, as a preferred solution, the support cylinder 101 includes a mounting rod 1011, a telescopic rod 1012 and a winding drum 1013. One end of the mounting rod 1011 is fixedly connected to the surface of the support plate 601, and the fixed end of the telescopic rod 1012 is fixedly connected to the other end of the mounting rod 1011. The winding drum 1013 is sleeved on the outside of the telescopic rod 1012 through a hole and is fixedly connected to the telescopic end of the telescopic rod 1012.

[0051] Through the connection between the mounting rod 1011 and the telescopic rod 1012, the mounting rod 1011 is used to support the telescopic rod 1012, and through the connection between the winding drum 1013 and the telescopic rod 1012, the telescopic end of the telescopic rod 1012 can drive the winding drum 1013 to move horizontally along the second direction. Through the action of the winding drum 1013, the enameled stranded wire can be wound and carried, and at the same time, a supporting drum for winding the enameled stranded wire can be detachably installed on the winding drum 1013. When the enameled stranded wire is completely wound on the supporting drum, the supporting drum can be removed for placement, and then another supporting drum can be replaced to pull and wind up other enameled stranded wires to be tested.

[0052] In this embodiment, as a preferred solution, the wire winding member 102 includes a driving motor 1021, a rotating disk 1022, a cross bar 1023, a wire fixing block 1024 and two wire fixing shafts 1025.

A through groove is provided on the side of the wire fixing block 1024, and the two wire fixing shafts 1025 are both rotatably connected in the through groove provided in the wire fixing block 1024. The outer surfaces of the two wire fixing shafts 1025 are spaced apart, and the wire fixing block 1024 is located outside the winding drum 1013.

[0053] Through the connection between the driving motor 1021 and the rotating disk 1022, the driving motor 1021 can drive the rotating disk 1022 to rotate, and through the connection between the rotating disk 1022 and the cross bar 1023, the cross bar 1023 rotates around the winding drum 1013, and through the connection between the cross bar 1023 and the wire fixing block 1024, the cross bar 1023 drives the wire fixing block 1024 to rotate around the winding drum 1013, and the enameled stranded wire passes through the wire fixing block 1024. One end of the mechanism 20 passes through the wire fixing block 1024 and passes between the two wire fixing shafts 1025. The two wire fixing shafts 1025 clamp the enameled stranded wire to a certain extent. Then the enameled stranded wire passes through one end of the wire fixing shaft 1025 and is fixed on the winding drum 1013. At the same time, the circuit is connected, and the wire fixing block 1024 is driven to rotate around the winding drum 1013 through the cross bar 1023, so that the enameled stranded wire is wound on the winding drum 1013, and traction is generated at the same time.

[0054] During the winding process, the telescopic rod 1012 controls the winding drum 1013 to move along the second direction, so that the enameled stranded wire is wound more evenly. When the winding stops, the telescopic rod 1012 of the telescopic rod 1012 also stops.
