[0003] In prior art, traditional inductor size detection frock often has some problems in the detection process.For example, during detection, inductor body is difficult to keep stable position, and it is easy to shake excessively in horizontal direction, which makes it difficult to maintain correct relative position relationship between inductor body and other components of detection frock, thereby greatly affecting the accuracy of detection result.

[0004] In addition, the line and element in detection frock are also susceptible to external environment.In actual production environment, dust, moisture and other interference factors are everywhere, and due to lack of effective protective measures, these interference factors are easy to enter the inside of frock, causing damage to line or element, and thereby affecting the normal work and service life of detection frock.

[0034] As shown in Figures 1 to 5 An inductor size detection tool, comprising: a bottom plate 1, an inductor body 14 and a protective plate 9, the bottom plate 1 is provided with a rectangular groove 2, the rectangular groove 2 is provided with a rectangular silica gel strip 4, the bottom plate 1 is provided with a lower end ring 3, the lower end of the bottom plate 1 is provided with a foot 5 through welding, the upper end of the bottom plate 1 is provided with a lower end ring 3, the outer side of the inductor body 14 is provided with a current detector 15, the lower end is provided with a data sensor 16, the front end of the protective plate 9 is provided with a terminal 8, one side of the protective plate 9 is provided with a gap, the gap is provided with a circular silica gel strip 13, and the two ends are fastened with a clamp 12 and a screw 11.

[0035] In the specific application of the embodiment of the utility model, first, the inductor body 14 is placed on the lower end ring 3 of the bottom plate 1, and the rectangular silica gel strip 4 in the rectangular groove 2 is used for preliminary positioning. Then, the protective plate 9 is connected with the external detection equipment through the terminal 8, and is ready for detection work. When the inductor works, the current detector 15 works according to the electromagnetic induction principle. When the current passes through the inductor, the magnetic field changes, the induction coil in the current detector 15 can sense the change of the magnetic field and convert it into an electric signal. According to the electric signal, the current size in the inductor can be calculated. If the size of the inductor changes, for example, the number of turns of the inductor coil or the spacing of the coil changes, the inductance value of the inductor will be affected, and then the current size will be affected. By monitoring the current, the relevant information of the size change of the inductor can be indirectly obtained. For example, if the inductor changes in size during the working process, the temperature data detected by the temperature sensor will deviate from the normal range; or if the size change causes the internal pressure to change, the pressure sensor will also detect abnormal data.

[0036] The data collected by the current detector 15 and the data sensor 16 are transmitted to the external equipment through the terminal 8 at the front end of the protective plate 9. The protective plate 9 protects the transmission lines. The gap structure of the circular silica gel strip 13 and the clamp plate 12 fastened by the screw 11 ensures the stability of the internal lines of the protective plate 9, preventing the lines from being disturbed or damaged during transmission. In the external equipment, the received data will be processed according to the pre-set algorithm. The collected current, temperature, pressure and other data are compared and analyzed with the standard size data model of the inductor. If the data is within the allowable error range, it is determined that the size of the inductor is qualified; if the data is out of range, it is determined that the size of the inductor is unqualified, and further analysis can be made to determine which factors (such as inductor coil deformation, core displacement, etc.) cause the size change.

[0037] In one possible implementation, the lower end of the protective plate 9 is pressed on the rectangular silica gel strip 4 of the bottom plate 1 around the lower end ring 3 to realize sealing, the upper end of the protective plate 9 is fixedly connected with the upper end ring 10, the inductor body 14 is inside the protective plate 9, and the inductor body 14 and the top end of the protective plate 9 are provided with the upper pressing plate 7.

[0038] In the specific application of the embodiment of the utility model, the protective plate 9 is pressed on the bottom plate 1 around the lower end ring 3, the position and shape of the lower end of the protective plate 9 are determined by the lower end ring 3, and the accuracy of the sealed connection between the protective plate 9 and the bottom plate 1 is ensured. The upper end of the protective plate 9 is fixedly connected with the upper end ring 10, and the upper and lower end rings jointly support and shape the protective plate 9, so that the protective plate 9 forms a regular shape to accommodate the inductor body 14. At the same time, it is also convenient for the assembly and disassembly of the tooling. When the inductor body 14 needs to be replaced or the tooling needs to be maintained, the protective plate 9 can be easily separated or assembled with the upper and lower end rings.

[0039] The upper pressing plate 7 cooperates with the top end of the protection plate 9, and when the inductor body 14 is placed, the upper pressing plate 7 can exert a certain pressure (the pressure needs to be moderate, which can fix the inductor body 14 and will not damage the inductor body 14) on the inductor body 14, so that the inductor body 14 is tightly attached to the preset position inside the protection plate 9. During the detection process, the upper pressing plate 7 can keep the position of the inductor body 14 stable in the vertical direction, so as to avoid the vertical displacement of the inductor body 14 due to its own weight or slight external vibration, thereby ensuring that the size data detected is obtained when the inductor body 14 is in the correct position.

[0040] In a possible implementation, a pull wire 6 is arranged between the upper pressing plate 7 and the bottom plate 1, and the data sensor 16 and the rectangular silica gel strip 4 on the bottom plate 1 are tightly contacted and completely sealed by pulling the pull wire 6 up and down. The shape of the upper pressing plate 7 is X-shaped, and the number of the terminal heads 8 is not less than two.

[0041] In the specific application of the embodiment of the utility model, when the pull wire 6 is pulled up and down, the upper pressing plate 7 will approach the bottom plate 1. Due to the pulling force of the pull wire 6, the upper pressing plate 7 will exert pressure on the data sensor 16, so that the data sensor 16 is tightly attached to the rectangular silica gel strip 4 on the bottom plate 1. The rectangular silica gel strip 4 itself has certain elasticity and sealing performance, and can fill the small gap between the data sensor 16 and the bottom plate 1 after being subjected to pressure, so as to achieve the effect of complete sealing.

[0042] In the sealed state, the data sensor 16 can accurately detect the size of the inductor. The data sensor 16 can obtain the size information of the inductor by using principles such as optical measurement and electromagnetic induction. For example, if the optical measurement principle is used, in a sealed and stable environment, light can be accurately projected onto the surface of the inductor and reflected back, and the data sensor 16 calculates the related size of the inductor according to the reflection time and intensity of the light. If the electromagnetic induction principle is used, the data sensor 16 can determine the size and other parameters of the inductor by detecting the magnetic field change around the inductor.

[0043] It should be noted that, in the present document, the terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device.

[0044] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.

[0045] The above describes the present application and its embodiments, which are not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired, without departing from the creative purpose of the present application, without creative design, similar structure and embodiments to the technical solution, which should belong to the protection scope of the present application.
