Description

Technical Field

[0001] The invention belongs to the technical field of enameled wire detection, and in particular relates to a detection device for enameled wire of an inductor element. Background Art

[0002] The enameled wire in the inductor component plays a vital role. As the path of current, the enameled wire can ensure that the current flows in the inductor component according to the designed path, thereby generating the required inductance effect. The insulating paint on the surface of the enameled wire can effectively prevent short circuits between wires and between wires and other components, ensuring the normal operation of the inductor component.

[0003] During the production and use of inductor components, enameled wire needs to withstand certain mechanical stress. If the tensile strength of the enameled wire is insufficient, it will break during installation, winding or operation, thus affecting the performance and reliability of the inductor component. By testing the tensile strength of the enameled wire, it can be ensured that it can withstand normal mechanical stress and ensure the stable performance of the inductor component. Enameled wire with strong tensile strength can better resist the action of external forces and reduce the occurrence of failures caused by mechanical damage, which helps to increase the service life of the inductor component and reduce the cost of maintenance and replacement. Therefore, the tensile strength of the enameled wire needs to be tested during its production.

[0004] At present, most people use tensile testers to test the tensile strength of enameled wires. Both ends of the enameled wire to be tested are fixed with clamps, and then a mechanical device is used to provide a pulling force to one end of the enameled wire to achieve rapid detection of the tensile strength of the enameled wire. The moving distance of the mechanical device determines the test range of the tensile strength of the enameled wire. Therefore, this type of test equipment requires a large space to accommodate the movement range of the mechanical device. Even for high-precision mechanical devices, it is difficult to achieve completely smooth linear motion. During speed adjustment and acceleration and deceleration, there will still be slight fluctuations, which will lead to an insufficient increase in tension, thereby affecting the accuracy of the test results.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Through the winding and pulling mechanism, mounting bracket, clamp, and transmission connection mechanism, the winding drum rotates at a uniform speed to provide continuous and relatively stable pulling force. The increase of pulling force is more linear, avoiding the additional damage to the enameled wire caused by sudden impact force, so that the test results can more accurately reflect the tensile performance of the enameled wire in actual use, and the test can be carried out in a relatively compact space, with relatively low requirements for the site.

[0023] 2. The set guiding diameter measuring mechanism, pressurized air supply mechanism and wire diameter feedback control mechanism can prevent the enameled wire near one end of the fixture from being excessively bent due to the tension direction not being parallel to the edge of the fixture, and avoid the problem that such excessive bending may cause the enameled wire to deform, thereby affecting the accuracy of the test results. The guiding mechanism can guide the stretching direction of the enameled wire to keep it consistent with the tension direction. It can also quickly detect and feedback the wire diameter size of the enameled wire to be tested while having a guiding function, and regulate the pulling detection speed based on the wire diameter size. The larger the wire diameter, the faster the pulling detection speed. Because under the same material, the larger the wire diameter, the stronger the tensile strength of the enameled wire. The faster the detection speed can effectively improve the detection efficiency.

[0024] 3. Through the detection angular velocity control mechanism and linear motor, the angular velocity of the take-up drum and the detection height of the take-up drum can be automatically adjusted during the detection process. When the enameled wire under test has good ductility and the enameled wire is wound around the take-up drum for more than one circle, the continued winding of the take-up drum will increase the diameter of the take-up drum due to the winding of the enameled wire. At this time, reducing the rotation angular velocity of the take-up drum can ensure the stability of the enameled wire pulling speed, and avoid changes in the actual tension applied to the enameled wire due to changes in the pulling speed. If the tension increases, the enameled wire will break prematurely, thereby affecting the evaluation of its true tensile performance. At the same time, the winding height of the take-up drum is reduced to avoid the problem that the direction of the tension of the enameled wire changes due to changes in the height of the clamp end and the take-up drum end during the tensile test, thereby affecting the accuracy of the test results.

[0025] 4. Through the intuitive display mechanism of the test results, the final test value in the tensile test can be displayed more intuitively and clearly, which is convenient for the staff to quickly obtain the specific test results and facilitate the detection work.

[0045] The transmission connection mechanism 8 includes a transmission plate 81 fixedly connected to one end of the driving shaft 22, and the side of the transmission plate 81 away from the driving shaft 22 is rotatably connected with a connecting shaft 82, and the end of the connecting shaft 82 away from the transmission plate 81 is fixedly connected to the side wall of the winding drum 23, and a torsion spring 83 sleeved on the outside of the connecting shaft 82 is fixedly connected between the transmission plate 81 and the winding drum 23, and a support plate 84 is fixedly connected to the side wall of the transmission plate 81. A fixed plate 85 corresponding to the support plate 84 is fixedly installed on the outer wall of the winding drum 23, and a confirmation switch 86 is fixedly installed on the side of the fixed plate 85 close to the support plate 84.

[0046] The PLC controller 12 is fixedly mounted on the upper end of the base 1 and is electrically connected to the winding and pulling mechanism 2, the guide diameter measuring mechanism 3, the pressurized air supply mechanism 4, the wire diameter feedback control mechanism 5, the detection angular velocity control mechanism 6 and the detection result intuitive display mechanism 7 respectively.

[0047] The operating principle of the present invention is described as follows: one end of the enameled wire to be tested is fixed on the fixture 11, and the other end is fixed on the winding drum 23, and the enameled wire is passed through the guide cylinder 31, the guide cylinder 31 guides and protects the enameled wire, and the height position of the guide cylinder 31 is adjusted based on the diameter of the enameled wire, so that the enameled wire is located at the center position of the guide cylinder 31 as much as possible, and the guide cylinder 31 is adjustably mounted on the mounting bracket 10. The adjustment mechanism here can be adjusted by means of a screw and a nut, which is a prior art and will not be described in detail here;

[0048] The PLC controller 12 controls the action of the electric push rod 42, and the electric push rod 42 pushes the pressurizing piston 43 to move in the pressurizing shell 41, and then the air in the pressurizing shell 41 is pressed and sent to the telescopic gas rod 32 through the air supply pipe 34, so that the moving end of the telescopic gas rod 32 drives the arc clamping plate 33 to move, and the upper and lower arc clamping plates 33 further clamp and lock the enameled wire until the arc clamping plate 33 is completely squeezed outside the enameled wire. At this time, the telescopic gas rod 32 can no longer push the arc clamping plate 33 to move, but the pressurizing piston 43 continues to move in the pressurizing shell 41, thereby increasing the air pressure in the pressurizing shell 41. When the air pressure sensor 44 detects that the air pressure in the pressurizing shell 41 reaches a preset value, the air pressure sensor 44 feeds back a signal to the PLC controller 12, and the PLC controller 12 controls the electric push rod 42 to stop moving;

[0049] When the pressurizing piston 43 moves, it drives the follower rack 57 to move synchronously, and the meshing action of the follower rack 57 and the follower gear 56 drives the regulating screw 52 to rotate, and then the threaded sleeve action of the regulating screw 52 and the regulating seat 53 makes the regulating seat 53 drive the feedback conductive contact piece 55 to slide on the feedback resistor rod 54. Specifically, when the diameter of the enameled wire is larger, the distance between the arc clamping plate 33 and the enameled wire is shorter, and then the less air in the pressurizing shell 41 can drive the telescopic gas rod 32 to push the arc clamping plate 33 to contact the outside of the enameled wire. At this time, the moving distance of the pressurizing piston 43 is shorter, so that the sliding distance of the feedback conductive contact 55 on the feedback resistor rod 54 is shorter, so that the access resistance of the feedback resistor rod 54 is smaller, and the feedback conductive contact 55 and the feedback resistor rod 54 are connected in series to the power supply circuit of the drive motor 25, and the drive motor 25 is a DC motor. The smaller the access resistance of the feedback resistor rod 54, the faster the rotation speed of the drive motor 25 will be, and the faster the rotation speed of the drive reel 23 will be, so that when the wire diameter of the enameled wire is larger, the tension test speed will be faster;

[0050] When the PLC controller 12 controls the electric push rod 42 to move, it synchronously controls the double-axis motor 210 in the winding drum 23 to move, and the double-axis motor 210 drives the two adjusting screws 211 to rotate synchronously. Through the threaded sleeve effect of the adjusting screw 211 and the adjusting block 212, the adjusting block 212 cooperates with the extension rod 213 to drive the two annular side baffles 215 to approach each other, so as to further block and limit the enameled wire. When the air pressure sensor 44 senses that the pressure signal meets the standard and feeds back to the PLC controller 12, the PLC controller 12 synchronously controls the double-axis motor 210 to stop moving. Specifically, the larger the diameter of the enameled wire, the faster the feedback signal of the air pressure sensor 44, and the shorter the rotation time of the double-axis motor 210, thereby making the distance between the two annular side baffles 215 larger, which is suitable for limiting the enameled wire with a large diameter.

[0051] The PLC controller 12 controls the action of the driving motor 25, and the driving motor 25 cooperates with the reduction gear box 24 to drive the driving shaft 22 to rotate. The driving shaft 22 drives the take-up drum 23 to rotate through the connection of the transmission plate 81, the connecting shaft 82 and the torsion spring 83 to tighten the enameled wire. When the enameled wire is tightened, the take-up drum 23 is in a relatively fixed state. As the transmission plate 81 continues to rotate, the torsion spring 83 between the transmission plate 81 and the take-up drum 23 is deformed and stores energy under force until the supporting plate 84 on the side wall of the transmission plate 81 is squeezed on the fixed plate 85 and the confirmation switch 86. The supporting plate 84 cooperates with the fixed plate 85 to continue to drive the take-up drum 23 to rotate, providing a pulling force to the enameled wire, and performing a tension test;

[0052] When the enameled wire has good ductility, the enameled wire can be wound on the winding drum 23 for more than one circle. Every time the enameled wire is wound around the winding drum 23, the support shaft 26 drives the arc-shaped trigger block 29 to move and press on the trigger switch 28. The trigger switch 28 feeds back a signal to the PLC controller 12, and the PLC controller 12 controls the servo motor 63 and the linear motor 9 to work for 3 seconds.

[0053] The servo motor 63 drives the transmission screw 62 to rotate. Through the threaded sleeve effect of the transmission screw 62 and the transmission seat 64, the transmission seat 64 drives the control conductive contact 66 to slide on the control resistor rod 65, thereby increasing the access resistance of the control resistor rod 65. The control conductive contact 66 and the control resistor rod 65 are connected in series to the power supply circuit of the drive motor 25, so that the rotation speed of the drive motor 25 is reduced, and the angular velocity of the winding drum 23 is reduced. Because the enameled wire wound outside the winding drum 23 will increase the winding diameter of the winding drum 23, as the diameter of the winding drum 23 increases, the radius of the enameled wire winding increases. Under the same winding angular velocity, according to the principle of circular motion, the linear velocity of the outer enameled wire will increase. According to the relationship between linear velocity and angular velocity: v (linear velocity) = ω (angular velocity) Speed)*R(radius), at this time, reducing the angular velocity of the take-up drum 23 can achieve the stability of the enameled wire pulling line speed, thereby ensuring the accuracy of the test results, and the feedback conductive contact 55 and the feedback resistor rod 54 are also connected in series to the power supply circuit of the servo motor 63. The servo motor 63 is a DC motor. When the diameter of the enameled wire is larger, the access resistance of the feedback resistor rod 54 is smaller, and the speed of the servo motor 63 is faster. Within the fixed working time of 3s, the larger the distance that the conductive contact 66 slides on the control resistor rod 65, the larger the access resistance of the control resistor rod 65, and the greater the reduction in the angular velocity of the take-up drum 23. Because the larger the diameter of the enameled wire, the greater the increase in the winding radius of the take-up drum 23. At this time, reducing the angular velocity more can ensure the stability of the pulling line speed;

[0054] When the PLC controller 12 controls the linear motor 9 to work for 3s, the linear motor 9 drives the winding and pulling mechanism 2 to move downward, thereby lowering the height of the winding drum 23. Because the enameled wire is wound around the winding drum 23 for more than one circle, the height of the enameled wire at one end of the winding drum 23 will be higher than the height of the enameled wire at one end of the clamp 11, thereby changing the pulling direction of the enameled wire, affecting the accuracy of the test result. By lowering the height of the winding drum 23, the heights of the two ends of the enameled wire can be balanced again to ensure the accuracy of the test result. The feedback conductive contact 55 and the feedback resistor rod 54 are also connected in series to the power supply circuit of the linear motor 9. The larger the wire diameter of the enameled wire, the smaller the access resistance of the feedback resistor rod 54, which makes the power supply current of the linear motor 9 larger and the working speed of the linear motor 9 faster, thereby making the linear motor 9 move downward more during the working 3s. The height of the winding drum 23 is adjusted more accurately based on the wire diameter of the enameled wire to ensure that the two ends of the enameled wire are on the same horizontal line to improve the test accuracy.

[0055] After the confirmation switch 86 is pressed and triggered, it indicates that the tension test officially begins, and the PLC controller 12 synchronously controls the synchronous motor 73 to operate. The synchronous motor 73 drives the synchronous screw 72 to rotate, and the threaded sleeve connection between the synchronous screw 72 and the movable seat 74 enables the movable seat 74 to drive the identification rod 76 to move relative to the tension scale plate 75 until the enameled wire is broken. At this time, under the reset action of the torsion spring 83, the winding drum 23 is offset relative to the transmission plate 81, so that the support plate 84 is separated from the pressing of the confirmation switch 86 on the fixed plate 85. At this time, the PLC controller 12 controls the synchronous motor 73 to stop operating. At this time, the identification rod 76 is located at the final position of the tension scale plate 75, which indicates the tensile strength of the enameled wire being tested.
