Description

Technical Field

[0001] This utility model relates to a device for producing conductors, and more particularly to a diameter measuring instrument for producing conductors. Background Technology

[0002] The conventional manufacturing process for fine conductors (such as jumper wires) includes wire drawing, monofilament annealing, conductor stranding (optional), insulation extrusion, and testing. The testing process includes measuring the overall outer diameter of the conductor. Current conductor manufacturing processes use sampling inspection, with manual sampling and conventional measuring tools such as calipers. This results in low testing efficiency and the test results cannot fully and reliably reflect the actual dimensions of the product. Summary of the Invention

[0003] This utility model provides a diameter measuring instrument for wire production; it solves the problem in the prior art that manual sampling and inspection leads to low detection efficiency and the detection results cannot fully and reliably reflect the actual size of the product.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: A diameter measuring instrument for wire production includes: an online detection base, a fixed detection wheel, a swing arm, a movable detection wheel, and a Hall sensor. The online detection base is horizontally rotatably provided with a first shaft and a second shaft. The fixed detection wheel is coaxially fixedly installed on the first shaft. The middle part of the swing arm is fixedly installed on the second shaft. A third shaft is horizontally rotatably provided on one end of the swing arm near the fixed detection wheel. The movable detection wheel is coaxially fixed on the third shaft and faces the fixed detection wheel. The other end of the swing arm extends to provide a lever arm. The end of the lever arm is provided with a permanent magnet. The Hall sensor is installed on the online detection base near the permanent magnet. The online detection base is also provided with an elastic element that drives the swing arm to deflect towards the fixed detection wheel. Both the movable detection wheel and the fixed detection wheel are provided with arc-shaped wire grooves.

[0005] This invention relates to an online inspection device that can measure the diameter of wires on a production line in real time. The online inspection base is fixed to the production line, and the wire is attached to the fixed inspection wheel. A swing arm, under the action of an elastic element, is kept tilted towards the wire, ensuring that the movable inspection wheel always presses against the wire. Therefore, the wire is rolled and clamped between the two inspection wheels. Changes in the wire's outer diameter cause the swing arm to swing slightly in sync, which in turn causes the permanent magnet to swing slightly in sync. This results in a change in the magnetic field, which is detected by a Hall sensor. The sensor sends an electrical signal to a signal acquisition unit, which then displays the signal visually on a screen. Depending on the type of wire produced, several preset reference ranges are available. When the actual detection signal value is within the corresponding reference range, the wire diameter meets the requirements. If the actual detection signal value exceeds or falls outside the reference range, the wire diameter does not meet the requirements.

[0006] Furthermore, the distance between the movable detection wheel and the second shaft is L1, and the distance between the permanent magnet and the second shaft is L2, with the ratio of L1 to L2 ranging from 1.5 to 2.5. Since the change in wire diameter is very small, to facilitate detection, this invention increases the swing amplitude of the permanent magnet within a certain range by increasing the ratio of L1 to L2. However, the increase needs to be controlled within a certain range; otherwise, even slight vibrations of the equipment itself will be amplified, thus affecting the observation of the visualized values.

[0007] Furthermore, this invention also includes an input guide wheel and an output guide wheel arranged relative to the horizontal axis of the online detection seat. The wire flows sequentially through the input guide wheel, the fixed detection wheel, and the output guide wheel, and the path of the wire is Ω-shaped. Under the action of the input guide wheel and the output guide wheel, the contact range between the wire and the fixed detection wheel is larger, which helps to maintain the stability of the wire and improve the detection accuracy.

[0008] Therefore, this utility model has the following characteristics compared with the prior art: 1. This utility model can measure the diameter of the wires on the production line in real time, and the detection is more comprehensive and efficient; 2. The overall structure is simple and the detection method is reliable. Attached Figure Description

[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] Example 1: See Figure 1 , Figure 2 and Figure 3 A diameter gauge for wire production includes: an online detection base 10, a fixed detection wheel 20, a swing arm 30, a movable detection wheel 40, and a Hall sensor 50. A first shaft 60 and a second shaft 70 are horizontally rotatable on the online detection base. The fixed detection wheel is coaxially fixedly mounted on the first shaft. The middle part of the swing arm is fixedly mounted on the second shaft. A third shaft 80 is horizontally rotatable on one end of the swing arm near the fixed detection wheel. The movable detection wheel is coaxially fixed on the third shaft and faces the fixed detection wheel. A lever arm 90 is extended from the other end of the swing arm. A permanent magnet 100 is provided at the end of the lever arm. A Hall sensor is installed on the online detection base near the permanent magnet. An elastic element 110 is also provided on the online detection base to drive the swing arm to deflect towards the fixed detection wheel. Both the movable and fixed detection wheels are provided with arc-shaped wire grooves 120.

[0016] This embodiment is an online inspection device that can measure the diameter of wires on a production line in real time. The online inspection base is fixed on the production line, and the wire is attached to a fixed inspection wheel. The swing arm is kept tilted towards the wire by the action of an elastic element, so that the movable inspection wheel is always pressed on the wire. Therefore, the wire is rolled and clamped between the two inspection wheels. Changes in the outer diameter of the wire will cause the swing arm to swing slightly in sync, which in turn causes the permanent magnet to swing slightly in sync. This will cause a change in the magnetic field. The Hall sensor can detect the minute changes in the magnetic field and send the electrical signal to the signal acquisition unit, which will finally display it on the screen in a visual way. Depending on the actual wire model produced, there are multiple preset reference ranges. When the value of the actual detection signal is within the corresponding reference range, it means that the wire diameter meets the requirements. If the value of the actual detection signal exceeds or does not reach the reference range, it means that the wire diameter does not meet the requirements.

[0017] See Figure 1 The distance between the movable detection wheel and the second shaft is L1, and the distance between the permanent magnet and the second shaft is L2. The ratio of L1 to L2 is between 1.5 and 2.5. Since the change in wire diameter is very small, this embodiment increases the swing amplitude of the permanent magnet within a certain range to facilitate detection. However, the increase needs to be controlled within a certain range; otherwise, even slight vibrations of the equipment itself will be amplified, thus affecting the observation of the visualized values.

[0018] See Figure 1 This embodiment also includes an input guide wheel 130 and an output guide wheel 140 positioned relative to the horizontal axis of the online detection seat. The wire flows sequentially through the input guide wheel, the fixed detection wheel, and the output guide wheel, forming an Ω-shaped path. Under the action of the input and output guide wheels, the contact range between the wire and the fixed detection wheel is larger, which helps maintain wire stability and improves detection accuracy.

[0019] See Figure 1 The online detection seat is provided with a spring seat 11, a positioning post 12 is inserted into the spring seat, and an elastic element is sleeved on the positioning post. One end of the elastic element abuts against the spring seat, and the other end abuts against the swing arm.

[0020] See Figure 3 and Figure 4 The online testing base has two mounting holes 13. The inner opening of the mounting hole forms a first shoulder 14. A bearing 150 is interference-fitted into the mounting hole. A flange cover 160 is installed in the outer opening of the mounting hole. The inner end of the flange cover abuts against the bearing. The first shaft and the second shaft are respectively interference-fitted with the two bearings.

[0021] See Figure 4 Both the first and second shafts are provided with snap ring grooves 170 and second shaft shoulders 180. Snap rings 190 are provided in the snap ring grooves. The snap rings and second shaft shoulders are respectively fitted to both sides of the bearing.

[0022] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
