[0033] Application Overview

[0034] With existing inductor components, the entire process still requires manual participation, and the continuity and stability of the detection are greatly affected by the factors of the detection personnel. Secondly, when manual inspection is adopted, it is difficult for the detection personnel to throw the workpiece on the voltage detection device into the second conveyor belt while picking up the workpiece to be tested on the first conveyor belt on the right side, thereby limiting the detection efficiency.

[0035] Based on the above technical problems, the present application proposes an inductance detection device, wherein the inductance detection device has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the inductance detection device provided by the present application is easy to produce and low-cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0036] Schematic inductance detection equipment,

[0037] refer to Figures 2 to 6According to a preferred embodiment of the utility model, an inductance detection device is used to detect a workpiece including a magnetic ring, and screen the quality of the magnetic ring in the workpiece through inductance testing. The device includes a machine base 10, a loading device 20, a feeding device 30, an inductance detection device 40 and a unloading device 50.

[0038] Specifically, the loading device 20, the feeding device 30, the inductance detection device 40 and the unloading device 50 are all arranged on the machine base 10. The loading device 20 is used to send the workpiece to be tested to a predetermined position. The feeding device 30 is used to grab the workpiece to be tested at the predetermined position and move it to the inductance detection device 40. The inductance value of the workpiece including the magnetic ring at a certain frequency is tested by the inductance detection device 40. If the measured value is within the qualified range, the qualified workpiece is sent to the unloading device 50 again by the feeding device 30.

[0039] Specifically, Figure 2 As shown, the inductance detection device 40 is located between the loading device 20 and the unloading device 50, and the inductance detection device 40 has a plurality of detection stations 401. In addition, the feeding device 30 includes a first manipulator 301 and a second manipulator 302. The first manipulator 301 is reciprocatingly slidably disposed between the loading device 20 and the inductance detection device 40, and the second manipulator 302 is reciprocatingly slidably disposed between the inductance detection device 40 and the unloading device 50.

[0040] It should be noted that, since the test time of a single workpiece placed on the inductance detection device 40 is mostly set to 1 to 2 minutes, within this time range, by setting the first manipulator 301, conditions are provided for grabbing multiple workpieces and placing them on multiple workstations of the inductance detection device 40. In addition, by setting the second manipulator 302, when grabbing the workpiece to be detected, if at this time one of the workpieces on the inductance detection device 40 has been detected, the second manipulator 302 can act at the same time and place the detected workpiece on the unloading device 50. Compared with the prior art, it is not easy for manual labor to place the detected workpiece on the unloading device 50 while placing the workpiece on the inductance detection device 40. The embodiment of the present application sets the first manipulator 301 and the second manipulator 302 to replace the hands of the detection personnel, which has the advantages of higher continuity of the detection process and helps to improve the continuity and stability of detection. In addition, since the inductance detection device 40 is technologically mature and widely used in the market, the specific structure and model of the inductance detection device will not be described here. The inductance detection device includes but is not limited to the inductance detection device disclosed in the patent document (CN201822009582.6) that can be used for inductance testing of magnetic rings.

[0041] More specifically, if Figure 2 As shown, the feeding device 30 also includes two first linear modules 303, the first linear modules 303 are fixedly mounted on the machine base 10, the first manipulator 301 is connected to a slider of one of the first linear modules 303, and the second manipulator 302 is connected to a slider of another of the first linear modules 303. When the motor on the corresponding first linear module 303 is energized, the corresponding slider rotates and drives the first manipulator 301 or the second manipulator 302 to follow the action, and the moving directions of the sliders of the two first linear modules 303 are both the length direction of the machine base 10.

[0042] In addition, in order to realize the lifting movement of the first manipulator 301 or the second manipulator 302, as shown in FIG. Figure 3 As shown, the feeding device 30 also includes two lifting components 304, each of the lifting components 304 includes a wire rod (not marked in the figure), a lifting seat 3041, and a first rotary drive motor (not marked in the figure), the lifting seat 3041 is connected to the slider of the corresponding first linear module 303, the wire rod is rotatably mounted on the lifting seat 3041, and one end of the wire rod is connected to the first rotary drive motor, the first manipulator 301 or the second manipulator 302 is arranged on the lifting seat 3041, when the first rotary drive motor is energized, the first manipulator 301 or the second manipulator 302 moves up and down along the height direction of the machine base 10.

[0043] In addition, in order to realize the circumferential rotation of the first manipulator 301 or the second manipulator 302, as shown in FIG. Figure 3 As shown, the feeding device 30 further includes a second rotary drive motor 305, each of the lifting seats 3041 is provided with a second rotary drive motor 305, the first manipulator 301 is connected to a second rotary drive motor 305, and the second manipulator 302 is connected to another second rotary drive motor 305. In addition, the first manipulator 301 and the second manipulator 302 each have an electric or pneumatic gripper.

[0044] It should also be noted that when a batch of the workpieces are scrapped before reaching their service life after leaving the factory or fail after being used for a period of time, technicians are required to collect a certain number of the workpieces and, based on the problem, reversely deduce which link the problem occurred in, whether it is a problem caused by processing or design. However, in the prior art, since the workpieces are not marked, it is difficult to trace the problems in processing later, which creates obstacles to product optimization and iteration.

[0045] In view of this, in the embodiments of the present application, Figure 2 As shown, the inductance detection equipment also includes an engraving device 60, which is arranged on the machine base 10, and the engraving device 60 is located on the side of the inductance detection device 40 away from the loading device 20, and the engraving device 60 is located at one end of the unloading device 50.

[0046] It should be noted that the engraving device 60 is further implemented as a laser engraving device. When the workpiece is tested and qualified by the inductance detection device 40, the laser engraving device 60 records a code for the workpiece that has passed the test. Each product corresponds to an independent code to facilitate subsequent traceability by manufacturers. Since the laser engraving device 60 is mature in technology and widely used in the market, the specific structure and model of the laser engraving device 60 are not described in detail here. The laser engraving device 60 includes but is not limited to the laser engraving device 60 disclosed in the patent document (CN113492265A).

[0047] Furthermore, in order to improve the continuity of feeding, Figure 2 and Figure 4 As shown, the loading device 20 includes a first loading plate 201 and a second loading plate 202, the first loading plate 201 is slidably and liftably arranged on the machine base 10, and the second loading plate 202 is slidably arranged on the machine base 10, and when the first loading plate 201 is lifted and lowered, the first loading plate 201 is located below the second loading plate 202 or the first loading plate 201 and the second loading plate 202 are located at the same horizontal height, and when the first manipulator 301 is located at one end of the machine base 10 where the loading device 20 is provided, the first loading plate 201 and the second loading plate 202 are alternately located directly below the first manipulator 301.

[0048] It should be noted that, assuming that the second loading plate 202 is located directly below the first manipulator 301 at this time, a number of workpieces to be tested waiting to be grasped are placed on the second loading plate 202. In addition, the second loading plate 202 is located below the first loading plate 201 at this time, and the first loading plate 201 is located on the side of the second loading plate 202 away from the first manipulator 301. At this time, a new batch of workpieces to be tested can be put into the first loading plate 201. When the number of workpieces to be tested on the second loading plate 202 is reduced, the first loading plate 20 1 slides toward the first manipulator 301 and is located directly below the second loading plate 202. When the number of workpieces to be tested on the second loading plate 202 is zero, the second loading plate 202 moves away from the first manipulator 301, and another batch of inductors to be tested can be put into the second loading plate 202 to wait for loading. At the same time, the first loading plate 201 located below the second loading plate 202 moves upward to the same level as the second loading plate 202, so that the first manipulator 301 can grab the workpieces to be tested on the first loading plate 201.

[0049] Specifically, Figure 4 As shown, the feeding device 20 also includes a lifting drive device 203, a second linear module 204, a third linear module 205, a sliding seat 206, an extension piece 207 and a plurality of heightening pieces 208. The bottom of the extension piece 207 is fixedly connected to the slider of the second linear module 204 and follows the movement. The other end of the extension piece 207 extends out of the top surface of the base 10 to a predetermined height and is connected to the second feeding plate 202. The second feeding plate 202 is located between the heightening piece 208 and the extension piece 207. By setting the heightening piece 208, it is ensured that the second feeding plate 202 will not contact the first feeding plate 202. There is motion interference in the height direction of a loading plate 201; in addition, the sliding seat 206 is fixedly connected to the slider of the third linear module 205 and follows the movement, the lifting drive device 203 is installed on the sliding seat 206, and the first loading plate 201 is fixedly connected to the push rod of the lifting drive device 203. When the second linear module 204 or the third linear module 205 is powered, the second loading plate 202 or the first loading plate 201 slides along the width direction of the machine base 10, and when the lifting drive device 203 is powered, the first loading plate 201 slides along the height direction of the machine base 10.

[0050] Furthermore, the unloading device 50 includes a second conveyor belt 501, the arrangement direction of the second conveyor belt 501 is parallel to the sliding direction of the first loading plate 201, and the arrangement direction of the first linear module 303 is perpendicular to the arrangement direction of the second conveyor belt 501, and the arrangement of the loading device 20, the feeding device 30 and the unloading device 50 forms a "concave" shape. It should be noted that the workpiece that passes the breakdown test and is engraved falls into the second conveyor belt 501 and is unloaded.

[0051] Furthermore, in order to prevent the workpiece from falling directly from a higher position onto the conveyor belt and damaging the workpiece surface, and when the engraving device 60 is engraving the workpiece, a placement platform is provided for the workpiece, such as Figure 2 and Figure 5 As shown, the inductance detection equipment also includes a receiving device 70, and the receiving device 70 is located between the engraving device 60 and the unloading device 50. The receiving device 70 includes a receiving plate 701, and the receiving plate 701 is rotatably mounted on the machine base 10 by a rotating motor.

[0052] It should be noted that the receiving plate 701 is normally arranged horizontally. When the workpiece passes the inductance detection test, the second manipulator 302 moves toward the receiving plate 701 and places the workpiece on the receiving plate 701. When the workpiece is engraved with a code, the receiving plate 701 rotates 60° to 90° toward the second conveyor belt 501, and the workpiece placed on the receiving plate 701 will fall onto the second conveyor belt 501 under the action of gravity.

[0053] In addition, if Figure 5 As shown, the receiving plate 701 also has a low threshold 7011, and the low threshold 7011 is located at one end of the receiving plate 701 close to the second conveyor belt 501. By setting the low threshold 7011, the workpiece will not fall until the receiving plate 701 rotates a large angle.

[0054] Further, in order to collect workpieces that fail the inductance detection test, such as Figure 2 , Figure 5 and Figure 6As shown, the inductance detection equipment also includes a waste collection component 80, and the waste collection component 80 includes a first guide plate 801, a second guide plate 802 and a first collection box 803. The first guide plate 801 and the second guide plate 802 are both arranged at an angle, and one end of the second guide plate 802 is fixedly connected to the first collection box 803. The first guide plate 801 is slidably set on the second guide plate 802. Specifically, an electric push rod is set on the back of the first guide plate 801, and the first guide plate 801 is connected to the push rod of the electric push rod. When the electric push rod is actuated, the first guide plate 801 can slide a predetermined distance to accommodate workpieces of different specifications and sizes.

[0055] Furthermore, if Figure 5 and Figure 6 As shown, the waste collection assembly 80 also includes a first conveyor belt 804, a third guide plate 805 and a second collection box 806. The machine base 10 has an inner cavity 101 and a drop port 102. The third guide plate 805 and the first conveyor belt 804 are both installed in the inner cavity 101, and the third guide plate 805 is arranged obliquely. The third guide plate 805 is located directly below the second collection box 806, and the lowest point of the third guide plate 805 is connected to the first conveyor belt 804. The second collection box 806 is arranged at one end of the first conveyor belt 804 away from the third guide plate 805, and the second collection box 806 is located directly below the unloading device 50. The volume of the second collection box 806 is greater than the volume of the first collection box 803.

[0056] It should be noted that unqualified workpieces can fall into the third guide plate 805 from the drop port 102 and slide along the third guide plate 805 to the first conveyor belt 804 , and the unqualified workpieces can be moved to the second collection box 806 through the first conveyor belt 804 .

[0057] Furthermore, if Figure 2 As shown, the first loading plate 201 and the second loading plate 202 each have at least three mounting holes 2011, and at least one of the mounting holes 2011 is located on one side of the line connecting the other mounting holes 2011, so as to facilitate the connection of the first loading plate 201 or the second loading plate 202 with an external hopper.

[0058] Furthermore, the engraving device 60 is movably mounted on the machine base 10 through a screw drive of a lead screw slider to accommodate the engraving of workpieces of various specifications.

[0059] In summary, the inductance detection device based on the embodiment of the present application is explained, which provides the inductance detection device with higher continuity in the detection process, helps to improve the detection continuity and stability and other advantages.

[0060] It is worth mentioning that in the embodiment of the present application, the inductance detection device has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency.
