Description

Technical Field

[0001] The present application relates to the technical field of inductor winding testing, and in particular to an inductor winding testing mechanism. Background Art

[0002] An inductor is a circuit component that generates an electromotive force due to changes in the current passing through it, thereby resisting changes in the current. The structure of an inductor is similar to that of a transformer, but it has only one winding. It is generally composed of a skeleton, winding, shielding cover, packaging material, magnetic core or iron core, etc. Inductors need to be tested for compliance during the production process.

[0003] Existing testing mechanisms usually include sensors, a driving structure and a test probe, which is then moved to detect the inductor winding. However, the existing test probe is usually exposed to the external environment when not in use. There is a lack of a protective structure on the outside. After a long time, the test probe may be damaged, thereby affecting the overall testing effect of the device. A Chinese patent (Announcement No.: CN221550755U) discloses an inductor winding testing mechanism. When the test mechanism is no longer in use, it can be stored in a storage box to reduce the phenomenon of inaccurate test structure caused by the test mechanism being exposed to the outside world for a long time.

[0004] The above document does not include a structure for fixing the inductor winding coil, which means that during testing, the staff must limit the inductor winding coil to ensure the stability of the electrical device during testing. This is also inconvenient to ensure that the inductor winding coil and the test probe are accurately fitted, thereby reducing test efficiency. Utility Model Content

[0005] In response to the deficiencies in the prior art, the present application provides an inductor winding testing mechanism that has the advantages of being easy to fix, thus solving the problem of inconvenient fixation.

[0006] To achieve the above objectives, the present application provides the following technical solutions: an inductor winding test mechanism, comprising a test chamber, a lifting structure provided inside the test chamber, a test plate fixed to the top of the lifting structure, two support plates fixed to the top of the test plate, test sensors fixed inside the two support plates, a placement table provided on the top of the test plate, and a clamping assembly provided inside the placement table;

[0007] The clamping assembly includes two groups of clamping blocks, two support rods, a connecting block fixedly installed at the lower end of the clamping block, a push rod fixedly installed at the opposite ends of the left and right groups of connecting blocks, a moving block fixedly installed at the other ends of the two groups of push rods, a driving structure fixedly installed inside the two moving blocks, and a rotating structure fixedly installed at the lower end of the placement table.

[0008] By adopting the above technical solution, the inductor coil can be stably fixed on the placement table for testing, so as to ensure the accuracy of the inductor coil test. The distance between the front and rear clamping blocks can also be adjusted according to the size of different inductor coils, which can effectively improve the practicality of the test.

[0009] Furthermore, two long holes are provided on the top of the placement platform for allowing two groups of connecting blocks to pass through the inside thereof, and the connecting blocks are slidably connected to the inside of the long holes.

[0010] By adopting the above technical solution, the connecting block can pass through the placement table so that the connecting block can be connected to the clamping block, so that when the two groups of connecting blocks move relative to or away from each other in the placement table, they can drive the clamping block to move on the top surface of the placement table.

[0011] Furthermore, the front and rear ends of the two support rods are respectively fixed to the front and rear walls of the inner cavity of the placement table, and the opposite ends of the front and rear groups of connecting blocks are each provided with a circular hole for allowing the support rods to pass through the interior.

[0012] By adopting the above technical solution, the connecting block can slide on the outer surface of the support rod so that the support rod can support the connecting block and prevent the connecting block from moving out of the placement table through the long hole, so that the two sets of clamping blocks can be in close contact with the top of the placement table.

[0013] Furthermore, the driving structure includes a twin-axis screw, a worm, a worm wheel fixedly mounted on the outer surface of the twin-axis screw, and a driving motor fixedly mounted on the output end of the worm.

[0014] The above technical solution is adopted to drive the two shifting blocks to move relative to or away from each other, so that the two shifting blocks can drive the front and rear groups of connecting blocks to move relative to or away from each other through the two groups of push rods.

[0015] Furthermore, the biaxial screw is located directly below the two support rods, the worm is located directly below the worm wheel, and the drive motor is fixed to the bottom wall of the inner cavity of the placement table.

[0016] The above technical solution is adopted to prevent the two support rods, the worm gear and the double-axis screw from affecting the normal work of each other.

[0017] Furthermore, the left and right ends of the biaxial screw are rotatably connected to the left and right walls of the inner cavity of the placement table through bearings respectively, and screw holes for the biaxial screw to pass through the interior are provided on the opposite sides of the left and right moving blocks.

[0018] By adopting the above technical solution, the double-axis screw can be stably rotated in the placement table, and the double-axis screw can drive the two moving blocks to move relative to or away from each other through the screw hole.

[0019] Furthermore, the rotating structure includes a turntable fixed to the lower end of the placement table, a rotating motor is fixed to the lower end of the turntable, and the rotating structure also includes a hidden slot opened at the top of the test board.

[0020] The above technical solution is adopted to drive the inductor coil on the placement table to rotate, so that the test sensor can test the presence of metal objects by the inductance change caused by the interaction between the inductor coil and the magnetic field, thereby improving the test range and accuracy.

[0021] Furthermore, the rotating motor is fixed to the bottom wall of the inner cavity of the hidden slot, and the turntable is rotatably connected to the inside of the hidden slot.

[0022] By adopting the above technical solution, the rotary motor can drive the turntable to rotate inside the test plate, so that the placement table can contact the test plate when rotating.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] This inductor winding testing mechanism, by providing a clamping assembly, can stably fix the inductor winding coil on a placement table for testing, thereby ensuring the accuracy of the inductor winding test. The spacing between the front and rear clamping blocks can also be adjusted according to the size of different inductor winding coils, which can effectively improve the practicality of the test. The inductance change caused by the interaction between the inductor winding coil and the magnetic field can also be used to test the presence of metal objects, thereby improving the test range and accuracy.

The front end of the chamber cover and the front side of the top of the test chamber 1 are both provided with embedded grooves for fixing the magnetic blocks and magnets therein, so that the chamber cover can fix the top of the test chamber 1 through the adsorption of the magnetic blocks and magnets.

[0033] See also Figures 1 to 3 The clamping assembly in this embodiment includes two groups of clamping blocks 61, two support rods 63, a connecting block 62 fixedly installed at the lower end of the clamping block 61, a push rod 64 fixedly installed at the opposite ends of the left and right groups of connecting blocks 62, a moving block 65 fixedly installed at the other ends of the two groups of push rods 64, a driving structure fixedly installed inside the two moving blocks 65, and a rotating structure fixedly installed at the lower end of the placement table 6.

[0034] Among them, two long holes are opened at the top of the placement table 6 for two groups of connecting blocks 62 to pass through the inside. The connecting blocks 62 are slidably connected to the inside of the long holes. The connecting blocks 62 can be fixed to the clamping blocks 61 through the long holes, so that the connecting blocks 62 can drive the clamping blocks 61 to move back and forth on the top surface of the placement table 6, and rubber pads are fixed on the opposite walls of the front and rear clamping blocks 61 to prevent the clamping blocks 61 from causing wear on the two ends of the inductor coil, which can effectively reduce the loss rate during the inductor coil testing process.

[0035] In addition, the front and rear ends of the two support rods 63 are respectively fixed to the front and rear walls of the inner cavity of the placement table 6, and the opposite ends of the front and rear groups of connecting blocks 62 are provided with round holes for the support rods 63 to pass through their interiors, so that the support rods 63 can support the connecting blocks 62 so that the connecting blocks 62 can move stably in the placement table 6, and can also prevent the connecting blocks 62 from moving out of the placement table 6 through the long holes, so that the two groups of clamping blocks 61 can be in close contact with the top of the placement table 6.

[0036] See also Figure 2 The driving structure in this embodiment includes a biaxial screw 66, a worm 68, a worm wheel 67 fixedly mounted on the outer surface of the biaxial screw 66, and a driving motor 69 fixedly mounted on the output end of the worm 68.

[0037] Secondly, the dual-axis screw 66 is located directly below the two support rods 63, and the worm 68 is located directly below the worm wheel 67 to prevent the dual-axis screw 66, the two support rods 63 and the worm 68 from affecting each other's normal operation. The drive motor 69 is fixed to the bottom wall of the inner cavity of the placement table 6, so that the drive motor 69 can drive the worm 68 to rotate in the placement table 6, so that the worm 68 can rotate firmly in the placement table 6.

[0038] In addition, the left and right ends of the double-axis screw 66 are respectively connected to the left and right walls of the inner cavity of the placement table 6 through bearings, so that the double-axis screw 66 can rotate stably in the placement table 6, and the opposite sides of the left and right moving blocks 65 are provided with screw holes for the double-axis screw 66 to pass through the interior, so that the double-axis screw 66 can drive the two moving blocks 65 to move relative to or away from each other through the screw holes, so that when the two moving blocks 65 move relative to or away from each other, they can pull or push the two groups of connecting blocks 62 in front and behind to move relative to or away from each other through the two groups of push rods 64.

[0039] See also Figure 3 The rotating structure in this embodiment includes a turntable 610 fixed to the lower end of the placement table 6, a rotating motor 611 is fixed to the lower end of the turntable 610, and the rotating structure also includes a hidden groove 612 opened at the top of the test plate 3.

[0040] At the same time, the rotating motor 611 is fixed to the bottom wall of the inner cavity of the hidden groove 612, and the turntable 610 is rotatably connected to the inside of the hidden groove 612, so that the rotating motor 611 can drive the turntable 610 to rotate in the test board 3, so that the bottom wall of the placement table 6 can contact the top wall of the test table 3, thereby preventing the placement table 6 from being in a suspended state during rotation, and allowing the placement table 6 to be stably rotated on the top wall of the test board 3.

[0041] It should be noted that the lifting structure 2, the test sensor 5 and the electronic components appearing in the text are all commonly known to the public in the prior art. The control method of this embodiment is controlled by a controller. The electrical components appearing in the text are all connected to the controller and the power supply. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also well known in the art, so the control method and circuit connection are no longer explained in detail in this utility model.

[0042] The working principle of the above embodiment is:

[0043] When in use, two or one inductor winding coils to be tested are placed between the front and rear groups of clamping blocks 61, so that the output end of the driving motor 69 drives the worm 68 to rotate, and when the worm 68 is engaged with the worm gear 67, the worm gear 67 can drive the double-axis screw 66 to rotate, so that the double-axis screw 66 can drive the left and right moving blocks 65 to move back to back. When the two moving blocks 65 move back to back, the front and rear groups of connecting blocks 62 can be pulled by the left and right groups of push rods 64 to move relative to each other, so that the connecting block 62 can drive the clamping block 61 to move, so that the two groups of clamping blocks 61 can clamp and fix one or two inductor winding coils on the placement table 6, so that the test sensor 5 can test the inductor winding coils. The inductor winding coils can be stably placed on the placement table 6 for testing, and the distance between the front and rear two clamping blocks 61 can also be adjusted according to the size of different inductor winding coils, which can effectively improve practicality.

[0044] Moreover, when the output end of the rotating motor 611 drives the turntable 610 to rotate in the hidden groove 612 of the test board 3, the turntable 610 can drive the placement table 6 to rotate on the top of the test board 3, so that the placement table 6 can drive the clamping assembly to rotate, so as to drive the inductor to rotate around the coil, so that the test sensor 5 can test whether the metal object exists by the inductance change caused by the interaction between the inductor around the coil and the magnetic field, thereby improving the test range and accuracy.
