Description

Technical Field

[0001] The utility model relates to the technical field of inductors, and in particular to an inductor core positioning tool. Background Art

[0002] An inductor coil is a device that works on the principle of electromagnetic induction. It is made of a wire wound around an insulating tube in a circle. The wires are insulated from each other, and the insulating tube can be hollow or contain an iron core or a magnetic powder core. When processing an inductor coil containing an iron core or a magnetic powder core, the iron core or the magnetic powder core needs to be fixed in the central through hole of the coil. The existing fixing method is to use a glue dispenser to dispense glue on the surface of the iron core or the magnetic powder core, and then insert it into the coil for fixing.

[0003] In the existing magnetic core dispensing, generally, a robot clamps the magnetic core and sends it to the dispensing structure for dispensing. However, when the magnetic core is transported to the clamping position of the robot through an external device, the magnetic core may tip over. If the robot clamps the tipped magnetic core and sends it to the dispensing structure for dispensing, part of the surface of the magnetic core will not be coated with glue, resulting in uneven glue coating on the surface of the magnetic core, which will cause the connection of the magnetic core to be unstable after being installed in the coil, and the magnetic core may be detached.

[0012] Compared with the prior art, one of the above technical solutions has the following beneficial effects:

[0013] Before gluing the core, the inductor core positioning tool of this embodiment is used to align the lateral and longitudinal sides of the core to prevent the core from tipping over, thereby preventing part of the core surface from being uncoated with glue, ensuring uniform glue coating, and ensuring a firm connection between the core and the coil.

Thus, features defined as "first", "second" and "third" may explicitly or implicitly include one or more of the features.

[0020] A preferred embodiment of the present application is as follows Figures 1 to 3 As shown, an inductor core positioning tool comprises a positioning base plate 1, and a U-shaped core positioning platform 2 and an I-shaped core positioning platform 3 are provided on the top of the positioning base plate 1; the U-shaped core positioning platform 2 comprises a U-shaped lateral alignment component 21 and a U-shaped longitudinal alignment component 22; the U-shaped lateral alignment component 21 is used to align the lateral sides of the U-shaped core, and the U-shaped longitudinal alignment component 22 is used to align the longitudinal sides of the U-shaped core; the I-shaped core positioning platform 3 is provided with an I-shaped lateral alignment component and an I-shaped longitudinal alignment component 32, the I-shaped lateral alignment component is used to align the lateral sides of the I-shaped core, and the I-shaped longitudinal alignment component 32 is used to align the longitudinal sides of the I-shaped core.

[0021] In the present embodiment, before the robot clamps the magnetic core to the dispensing structure, the robot first clamps the magnetic core to the inductor core positioning tooling of the present embodiment for positioning and alignment; specifically, if the robot clamps a U-shaped magnetic core, the robot clamps the U-shaped magnetic core to the U-shaped magnetic core positioning platform 2, and then the U-shaped lateral alignment component 21 aligns the lateral sides of the U-shaped magnetic core, and the U-shaped longitudinal alignment component 22 also aligns the longitudinal sides of the U-shaped magnetic core, so that the longitudinal sides and lateral sides of the U-shaped magnetic core are aligned respectively, thereby avoiding the U-shaped magnetic core from tipping over. Similarly, if the manipulator clamps and delivers an I-type magnetic core, the manipulator clamps and delivers the I-type magnetic core to the I-type magnetic core positioning assembly, and then the I-type lateral alignment assembly aligns the lateral sides of the I-type magnetic core, and the I-type longitudinal alignment assembly 32 also aligns the longitudinal sides of the I-type magnetic core, so that the longitudinal sides and lateral sides of the I-type magnetic core are aligned respectively, avoiding the side flipping of the I-type magnetic core. Therefore, before the magnetic core is glued, the inductor magnetic core positioning tool of this embodiment is used to align the lateral sides and longitudinal sides of the magnetic core, avoiding the side flipping of the magnetic core, thereby avoiding the surface of the magnetic core part not being coated with glue, ensuring uniform glue coating, and ensuring the connection between the magnetic core and the coil is stable. More preferably, in the inductor magnetic core positioning tool of this embodiment, a U-shaped magnetic core positioning platform 2 and an I-shaped magnetic core positioning platform 3 are provided at the same time, so that both U-shaped and I-shaped magnetic cores can be positioned and aligned, increasing the scope of use of the inductor magnetic core positioning tool. In this embodiment, the above-mentioned lateral direction is the front-to-back direction, and the above-mentioned longitudinal direction is the left-right direction.

[0022] Specifically, the U-shaped transverse alignment component 21 includes a mounting post 211, a U-shaped transverse clamp 212 and two U-shaped transverse alignment plates 213; the bottom end of the mounting post 211 is fixedly mounted on the positioning base plate 1, and the mounting post 211 extends vertically upward to one longitudinal side of the U-shaped magnetic core positioning platform 2; one end of the U-shaped transverse alignment plate 213 is fixedly connected to the clamping claw of the U-shaped transverse clamp 212, and the other end of the U-shaped transverse alignment plate 213 extends longitudinally to the side of the U-shaped magnetic core positioning platform 2 away from the mounting post 211, so that the U-shaped transverse clamp 212 can drive the two U-shaped transverse alignment plates 213 to move relative to each other in the transverse direction.

[0023] In this embodiment, when it is necessary to align the two lateral sides of the U-shaped magnetic core, the U-shaped lateral clamp 212 drives the two U-shaped lateral alignment plates 213 to approach each other, thereby beating the U-shaped magnetic core placed on the U-shaped magnetic core positioning platform 2 so that the two lateral sides of the U-shaped magnetic core are aligned.

[0024] More preferably, the U-shaped magnetic core positioning platform 2 is provided with a transverse limiting plate 23 .

[0025] The purpose of such a configuration is to prevent the two U-shaped transverse alignment plates 213 from excessively moving when approaching each other, thereby preventing the U-shaped transverse alignment plates 213 on both sides from crushing the U-shaped magnetic core, thereby ensuring the structural integrity of the U-shaped magnetic core.

[0026] Specifically, the U-shaped longitudinal alignment component 22 includes a U-shaped longitudinal clamp 221 and two U-shaped longitudinal alignment claws 222; the U-shaped longitudinal clamp 221 is fixedly installed under the U-shaped magnetic core positioning platform 2; the two U-shaped longitudinal alignment claws 222 are respectively fixedly installed on the two clamping claws of the U-shaped longitudinal clamp 221, so that the U-shaped longitudinal clamp 221 can drive the two U-shaped longitudinal alignment claws 222 to move relative to each other in the longitudinal direction; the U-shaped longitudinal alignment claws 222 include two first vertical alignment parts 2221 that are arranged in a transversely symmetrical manner; the top of the U-shaped magnetic core positioning platform 2 is provided with two first strip grooves 20 that are arranged in a transversely symmetrical manner; the top of the first vertical alignment part 2221 passes through the first strip groove 20 and extends to the top of the U-shaped magnetic core positioning platform 2.

[0027] The manipulator places the U-shaped magnetic core between the two U-shaped longitudinal snapping claws 222, and then the U-shaped transverse alignment component 21 snaps the U-shaped magnetic core, and then the U-shaped longitudinal clamp 221 drives the two U-shaped longitudinal snapping claws 222 to approach each other, so that the two first vertical snapping parts 2221 of the U-shaped longitudinal snapping claws 222 push the longitudinal sides of the U-shaped magnetic core, so that the longitudinal sides of the U-shaped magnetic core are aligned. It is worth noting that the alignment of the transverse sides and the longitudinal sides of the U-shaped magnetic core are not divided into front and back, and the transverse sides can be aligned first, and then the longitudinal sides; or the longitudinal sides can be aligned first, and then the transverse sides; or the longitudinal and transverse sides can be aligned at the same time.

[0028] Specifically, the I-type lateral alignment component includes a plurality of I-type lateral clamps 310, which are arranged in an interlaced manner on the I-type magnetic core positioning platform 3 along the lateral direction, and the driving ends of the plurality of I-type lateral clamps 310 are all facing the center lines of the lateral sides of the I-type magnetic core positioning platform 3.

[0029] In this embodiment, after the I-type magnetic core is clamped by the manipulator to between the two clamping jaws of the I-type transverse clamp 310, the two clamping jaws of the I-type transverse clamp 310 are close to each other, so as to align the two lateral sides of the I-type magnetic core.

[0031] In this embodiment, the I-type magnetic core is clamped by the manipulator and sent between the two second vertical aligning parts 3221 which are parallel in the longitudinal direction, and then the I-type longitudinal clamp 321 drives the two I-type longitudinal aligning plates 322 to approach each other, so that the two second vertical aligning parts 3221 which are parallel in the longitudinal direction are close to each other, so that the longitudinal sides of the I-core magnetic core are aligned by the two second vertical aligning parts 3221 which are parallel in the longitudinal direction. More preferably, in this embodiment, the I-type magnetic core positioning platform 3 is provided with a plurality of I-type longitudinal clamps 321 which are staggered in the transverse direction, and two second vertical aligning parts 3221 which are parallel in the longitudinal direction are provided between the two clamping claws of the I-type longitudinal clamp 321. Therefore, the I-type magnetic core positioning platform 3 can simultaneously position multiple I-type magnetic cores. Compared with the positioning of a single I-type magnetic core, the I-type magnetic core positioning platform 3 of this embodiment can reduce the positioning time of the I-type magnetic core and improve the positioning efficiency of the I-type magnetic core, thereby improving the assembly efficiency of the inductor, and can reduce the number of I-type longitudinal clamps 321, thereby reducing the production cost of the inductor magnetic core positioning tooling.
