[0024] Example:

[0025] Reference Figures 1-4The utility model provides an iron core inductance sorting machine, including workbench 1, the bottom of workbench 1 is provided with support column for guaranteeing the stable operation of motor 2, still include: the subunit for the subpackaging of the iron core to be detected is set up on workbench 1, the detection unit for the inductance detection of the iron core in the subunit is set up on workbench 1, the iron core after detection is completed on the subunit is grabbed for the subpackaging unit and is set up on workbench 1, and the sorting unit is electrically connected between the detection unit, is used for sorting according to the detection result of the iron core.

[0026] Referring to Figure 1-Figure 2 The subpackaging unit includes a motor 2 fixedly connected to the workbench 1, a rotating shaft 3 rotatably connected to the side of the workbench 1 away from the motor 2, a rotating disc 4 fixedly connected to the end of the rotating shaft 3 away from the workbench 1, and a plurality of support grooves 5 formed in the side of the rotating disc 4 away from the workbench 1. The output end of the motor 2 is connected to the rotating shaft 3, and the support grooves 5 are evenly distributed on the rotating disc 4.

[0027] It should be explained that the rotating disc 4 is usually connected to a vibrating disc feeder for making the iron cores enter the support grooves 5 one by one. The support grooves 5 are used for supporting and fixing the iron cores and provide an operation platform. The size of the support grooves 5 and the distance between two adjacent support grooves 5 are not limited and can be adjusted according to specific conditions.

[0028] Referring to Figure 1-Figure 2 The detection unit includes a test head 6 and a support 7 fixedly connected to the workbench 1, and a test rod 8 fixedly connected to the support 7. The test rod 8 and the test head 6 are located on the upper and lower sides of the same support groove 5, respectively.

[0029] The specific structure of the test rod 8 and the test head 6 can refer to the technical solutions in the prior art, and those skilled in the art can know that the inductance of the iron core can be detected when the iron core rotates between the test rod 8 and the test head 6.

[0030] Referring to Figure 1-Figure 3 The grabbing unit includes a rotating rod 9 rotatably connected to the workbench 1, an installation plate 10 fixedly connected to the end of the rotating rod 9 away from the workbench 1, and a permanent magnet 11 fixedly connected to the end of the installation plate 10 away from the rotating rod 9. When the installation plate 10 rotates to the side close to the rotating disc 4, the permanent magnet 11 is located above the support groove 5.

[0031] Referring to Figure 2-Figure 3 The utility model also includes a driving wheel 12 fixedly connected to the rotating shaft 3, an acceleration wheel 13 fixedly connected to the rotating rod 9, and a belt 14 sleeved between the driving wheel 12 and the acceleration wheel 13.

[0032] The diameter ratio between the driving wheel 12 and the accelerating wheel 13 can be set according to the size of the mounting plate 10 and the distance between the two adjacent groups of support grooves 5, so that when the last support groove 5 is rotated to the position below the permanent magnet 11, the mounting plate 10 is just rotated by one turn, the continuous sorting of the ferrite magnetic core is realized, and the sorting efficiency of the ferrite magnetic core is improved.

[0033] With reference to Figure 1 And Figure 4 The sorting unit comprises a collecting hopper 15 fixedly connected to the workbench 1, a guide groove 16 is formed in the side of the collecting hopper 15 close to the rotating rod 9, two groups of distributing plates 17 are symmetrically and rotatably connected to the collecting hopper 15, a first electromagnet 18 and a second electromagnet 19 are arranged on the side of the distributing plates 17 close to each other, and an elastic limiting piece 20 is fixedly connected between the two groups of distributing plates 17, wherein the height of the side of the collecting hopper 15 close to the mounting plate 10 is matched with the height of the permanent magnet 11, the guide groove 16 is inclinedly arranged along the rotating direction of the mounting plate 10, the first electromagnet 18 and the second electromagnet 19 are electrically connected between the testing head 6 and the testing rod 8, and the first electromagnet 18 is located above the second electromagnet 19.

[0034] In this embodiment, the magnetism of the first electromagnet 18 and the second electromagnet 19 when not energized is not limited, as long as the first electromagnet 18 or the second electromagnet 19 can generate an attractive force with the other first electromagnet 18 or second electromagnet 19, wherein it is explained that when the ferrite magnetic core detected by the testing head 6 and the testing rod 8 is a qualified product, the second electromagnet 19 is energized; when the ferrite magnetic core detected by the testing head 6 and the testing rod 8 is a substandard product, the first electromagnet 18 is energized, and the second electromagnet 19 is energized; under the action of the elastic limiting piece 20, the end portions of the distributing plates 17 are not attached to each other, and the first electromagnet 18 and the second electromagnet 19 are connected to the testing head 6 and the testing rod 8 through a delay circuit.

[0035] In the utility model, when the ferrite magnetic core is sorted, the ferrite magnetic core is placed in the support groove 5 through the vibrating disc feeder, and the rotating disc 4 is rotated under the action of the motor 2; when the ferrite magnetic core is rotated to the position between the testing head 6 and the testing rod 8, the ferrite magnetic core can be detected; if the ferrite magnetic core is a qualified product, the lower portions of the distributing plates 17 are relatively close to each other under the action of the second electromagnet 19 (i.e., when the ferrite magnetic core is conveyed to the collecting hopper 15, the lower portions of the distributing plates 17 are relatively close to each other); when the ferrite magnetic core after detection is rotated to the position of the next support groove 5, the mounting plate 10 is just rotated to this position, the ferrite magnetic core is adsorbed by the permanent magnet 11, the ferrite magnetic core is conveyed to the collecting hopper 15, and under the action of the guide groove 16, the ferrite magnetic core on the permanent magnet 11 can be taken off and falls along the collecting hopper 15 and the distributing plates 17;

[0036] If it is detected as a defective product, the principle and process are similar to the above, except that the upper part of the dividing plate 17 is in a closed state, and the falling ferrite core passes through the outside of the dividing plate 17, so that the ferrite core can be sorted through different positions of the collecting bucket 15 (it should be explained that during the falling process of the ferrite core, the first electromagnet 18 and the second electromagnet 19 have little effect on the ferrite core, and the ferrite core will not be adsorbed on the first electromagnet 18 or the second electromagnet 19).

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
