Description

TECHNICAL FIELD

[0001] The utility model relates to cable technical field especially is related to a copper wire diameter's multichannel dynamic detection device. BACKGROUND

[0002] Cables generally need to be twisted by multiple copper wires, and some are twisted by wires made of other materials, but they all need to be twisted to form a complete cable, and the cable needs to be immediately coated with an insulating layer and a signal shielding layer after twisting.

[0003] The thickness of twisted cables has certain design standards, which will affect the toughness and quality of the cable.

[0004] The diameter of a single twisted copper wire is even more important. Changes in the diameter of the copper wire used to twist the cable will affect the quality of the finished cable, especially the electrical conductivity and resistance, and will also interfere with the heat output and current carrying capacity of the cable.

[0005] Therefore, when making a twisted cable, the diameter of a single copper wire needs to be detected to ensure that the diameter error of the wire does not exceed the design range. Generally, the diameter error of a single copper wire needs to be controlled within 0.1mm.

[0006] The current detection method for single copper wire is mainly through mechanical linkage, which directly limits the diameter of the copper wire. The copper wire is detected through a designed channel. If it cannot pass, it means that the copper wire diameter is uneven or too thick, and if it swings or shakes, it means that the copper wire diameter is too thin. Please explain the current old detection scheme in detail:

[0007] This detection method is prone to cause wear of the copper wire, and the diameter of the worn copper wire has already changed. This small change will also affect the cable parameters after copper wire twisting. At the same time, this detection method is affected by temperature and vibration, resulting in obvious detection error. This detection method needs to detect the copper wire one by one in advance, which is low in detection efficiency and cannot match the cable twisting process to form a complete production line.

[0008] Therefore, the utility model designs a copper wire diameter multichannel dynamic detection device to solve the above problems. UTILITY MODEL CONTENTS

[0043] Please refer to Figs. 1 to 6 The utility model provides a kind of multi-channel dynamic detection device of copper wire diameter, to better understand the above technical solution, the above technical solution will be explained in detail below in combination with the drawings and specific embodiment of the specification.

[0044] In one specific embodiment of the technical scheme of the utility model:

[0045] Including chassis 1, bottom support 2, guide wheel 3 and laser detector 4;

[0046] The bottom frame 1 is a stable support frame, and a frame plate 11 is further fixedly arranged on the top of the bottom frame 1. The bottom frame 1 is stably mounted on a detection device. The top of the bottom frame 1 is parallel to the top of the frame plate 11, which facilitates the detection of the advancing copper wire and the installation and positioning of subsequent other detection devices. The frame plate 11 has a gantry structure and is used for supporting the translation motor 41 without affecting the normal advancement of the copper wire below the frame plate 11.

[0047] The bottom support 2 has a long strip plate structure. One bottom support 2 is arranged on each of the front and rear sides of the top of the bottom frame 1. Each bottom support 2 is mounted on the top of the bottom frame 1 along the left and right sides.

[0048] A plurality of wire guide rods 21 are vertically arranged on the bottom support 2. The wire guide rod 21 is a smooth round rod. The axes of the wire guide rods 21 on the same bottom support 2 are in the same vertical plane. Each two wire guide rods 21 form a group. Each group of wire guide rods 21 is arranged on the left and right sides of the copper wire advancement path. Each group of two wire guide rods 21 forms a channel for clamping the copper wire. Each copper wire advances in the channel formed by a group of wire guide rods 21.

[0049] The channel spacing of each group of two wire guide rods 21 is greater than the diameter of the advancing copper wire, and the gap is not more than 0.1 mm.

[0050] The positions of the wire guide rods 21 on the top of the front and rear side bottom supports 2 correspond to each other. That is, the axes of the channels formed by each group of wire guide rods 21 need to be kept coincident. This ensures that the copper wire can be constrained to advance in the channel formed by the guide rod 21, avoids winding caused by vibration and tension changes during advancement, and ensures that the copper wire is constrained within the detection range of the matching laser detector 4.

[0051] The guide wheel 3 is a roller with a guide groove. The guide wheel 3 is fixedly arranged on the top of an adjusting seat 31.

[0052] A plurality of adjusting seats 31 are locked on the top of the bottom support 2 and can be adjusted in the left and right directions.

[0053] The guide wheel 3 is a V-groove bearing roller, and the guide wheel 3 is wrapped with a rubber pad.

[0054] A guide rail 32 is further arranged on the bottom support 2. The guide rail 32 is mounted on the top of the bottom support 2 in the left and right directions. One guide rail 32 is arranged on each of the front and rear sides of the bottom support 2. The axes of the front and rear bottom supports 2 and the two guide rails 32 are arranged in parallel to each other.

[0055] The adjusting seat 31 is locked on the guide rail 32 through a bolt.

[0056] The matching surface of the adjusting seat 31 and the guide rail 32 is a dovetail groove. The structure of the dovetail groove can make the matching between the adjusting seat 31 and the guide rail 32 more stable and the structure more firm.

[0057] The guide rail 32 is arranged outside the wire rod 21, and the outside refers to the position outside the chassis 1 of the device, so the wire rod 21 is relatively inside the guide rail 32. The guide wheel 3 on the adjusting seat 31 is in direct contact with the front and rear processes, and the guide wheel 3 rolls more smoothly, facilitating the guidance of the copper wire, and the position of the wire rod 21 is relatively fixed, so that the guidance direction of the copper wire is more stable.

[0058] A guide wheel 3 is arranged outside each group of wire rods 21; the midpoint of the connecting line between the two wire rods 21 in each group coincides with the front and rear direction axis of the corresponding guide wheel 3, and the secondary structure is to ensure that the copper wire running direction is straight;

[0059] The laser detector 4 is a laser displacement sensor matrix, which is commonly used for diameter, displacement and spacing detection of industrial equipment. The laser detector 4 is locked on the mounting bracket 42. The translation motor 41 is a linear motor. The translation motor 41 is installed on the top of the frame plate 11. The mounting bracket 42 is locked on the translation motor 41. Each laser detector 4 can be transversely translated above the chassis 1 by the translation motor 41. The moving track of the translation motor 41 is horizontally arranged. The translation motor 41 can conveniently adjust the position of the mounting bracket 42 and the left and right direction position of the laser detector 4, so as to conveniently adjust the whole structure. Especially when the device runs for a period of time, the running of the copper wire and the tension of the front and rear processes on the copper wire will affect the horizontal position of the copper wire. The position of the laser detector 4 can be conveniently adjusted to match the change of the running direction of the copper wire.

[0060] Each laser detector 4 is arranged above the running route of the copper wire to be detected, and the detection direction of the laser detector 4 is opposite to the top of the chassis 1. The number of laser detectors 4 needs to correspond to the number of copper wires, that is, each copper wire needs a single laser detector 4 for detection, so as to ensure that the detection data can be traced.

[0061] The distance sensor 43 is arranged on the mounting bracket 42, and the detection direction of the distance sensor 43 is opposite to the top of the chassis 1. Two or more distance sensors 43 can be arranged on the mounting bracket 42. Through the detection of the distance sensor 43, the parallel state between the mounting bracket 42 and the top of the chassis 1 can be known, as long as the distance is the same.

[0062] Then the detection direction of each laser detector 4 on the mounting bracket 42 and the chassis 1 can be confirmed.

[0063] In use, the plurality of copper wires are arranged and guided through the V-shaped groove on the guide wheel 3 at the front end, so that the running direction of the copper wire is accurate and not easy to jump off.

[0064] Then the copper wire enters the passage between the two wire rods 21, also to ensure that the copper wire does not jump out of the other detection stations.

[0065] The copper wire travels below the shelf plate 11, and is detected by the laser detector 4 installed on the shelf plate 11 to ensure that the diameter of the copper wire is within the qualified range, and the copper wire continues to travel backward, guided by the wire rod 21 and the guide wheel 3 on the rear side to leave the device, and is stranded to form a complete cable in the subsequent process. When the diameter of the copper wire is detected to be abnormal, the control system can stop the wire laying equipment at the front end, and also stop the stranding equipment at the rear end process, adjust the copper wire, and cut off the unqualified product, thereby effectively improving the product quality.

[0066] The front-rear direction of the device refers to the front-rear direction of the copper wire, the direction in which the copper wire enters the device is the front end, and the side from which the copper wire leaves the device is the rear end. The left-right sides of the direction in which the copper wire travels are the left-right direction, and the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the utility model.

[0067] Although the specific embodiments of the utility model are described above, those skilled in the art should understand that the specific examples described are only illustrative, and are not used to limit the scope of the utility model. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the utility model should be covered within the scope of protection of the claims of the utility model.
