Description

Technical Field

[0001] This utility model relates to the field of nanocrystalline magnetic core processing technology, and in particular to a nanocrystalline magnetic core dispensing support fixture. Background Technology

[0002] In the production and processing of nanocrystalline magnetic cores, dispensing is a crucial step, and its quality directly affects the performance of the core. However, the support fixtures currently used for dispensing nanocrystalline magnetic cores have many problems.

[0003] General-purpose fixtures are difficult to use for precise positioning of ring-shaped or C-shaped nanocrystalline magnetic cores, which can easily lead to deviations in the dispensing position and thus affect product quality.

[0004] Specialized jigs can usually only fit magnetic cores of specific shapes or sizes. For C-type magnetic cores and toroidal magnetic cores with different opening sizes, different jigs need to be changed, which not only increases production costs but also increases the complexity of operation and reduces production efficiency. Utility Model Content

[0005] (I) Technical Issues

[0006] This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, the purpose of this utility model is to propose a nanocrystalline magnetic core dispensing support fixture, which addresses the problems of inaccurate positioning, poor adaptability, and inability to simultaneously meet the dispensing support requirements of annular and C-shaped nanocrystalline magnetic cores with different opening sizes in existing nanocrystalline magnetic core dispensing support fixtures.

[0008] (II) Technical Content

[0009] To achieve the above objectives, this utility model proposes a nanocrystalline magnetic core dispensing support fixture comprising a worktable and positioning mechanisms distributed on the worktable. The positioning mechanisms are used to position and support annular or C-shaped nanocrystalline magnetic cores of the same inner diameter. Specifically:

[0010] The positioning mechanism includes an arc-shaped fixed plate and arc-shaped movable plates symmetrically slidably connected to both sides of the arc-shaped fixed frame. By adjusting the position of the two sets of arc-shaped movable plates on the arc-shaped fixed plate, the opening on the front side of the arc-shaped fixed plate can be reduced or closed. When reduced, it can be adapted to C-shaped nanocrystalline magnetic cores with different opening sizes. When closed, it can be adapted to annular nanocrystalline magnetic cores.

[0011] In use, adjust the positions of the two sets of arc-shaped movable plates on the arc-shaped fixed plate according to the shape of the nanocrystalline magnetic core to be dispensed, and then place the annular or C-shaped nanocrystalline magnetic core to be dispensed on the support frame composed of the arc-shaped fixed plate and the two sets of arc-shaped movable plates to facilitate dispensing by the dispensing machine.

[0012] In addition, the nanocrystalline magnetic core dispensing support fixture proposed above according to this utility model may also have the following additional technical features:

[0013] Preferred technical solution 1: Elastic protrusions are embedded in the middle of the rear wall of the arc-shaped fixed plate and the outer wall of the arc-shaped movable plate, and the elastic protrusions achieve an interference fit with the inner ring of the nanocrystalline magnetic core.

[0014] Preferred technical solution two: To ensure that the front opening of the C-type nanocrystalline magnetic core is aligned with the front opening of the support frame when it is placed on the support frame, and to avoid misalignment of the C-type nanocrystalline magnetic core, radial movable baffles are provided on both sides of the opening of the support frame, that is, at the front end of the arc-shaped movable plate. When loading the C-type nanocrystalline magnetic core, the radial movable baffles at the front end of the two sets of arc-shaped movable plates extend outward along the front end of the arc-shaped movable plates, forming a left and right blocking structure for the front opening of the support frame, so that the two end walls of the front opening of the C-type nanocrystalline magnetic core contact the left and right blocking structures respectively and are limited by them.

[0015] When installing the annular nanocrystalline magnetic core, the radial movable baffle is moved inward to the inside of the support frame to avoid affecting the installation of the annular nanocrystalline magnetic core.

[0016] Specifically, a hole is provided at the front end of the arc-shaped movable plate, and the radial movable baffle can move inward and outward along the radial direction of the support frame through the hole.

[0017] Preferred technical solution 3: Arc-shaped track grooves are provided on both the left and right sides of the arc-shaped fixed plate. The sliders with inward protrusions at the tail ends of the two sets of arc-shaped movable plates extend into the two sets of arc-shaped track grooves respectively and slide back and forth along the arc-shaped track grooves to adjust the size of the opening on the front side of the support frame.

[0018] An arc-shaped auxiliary plate, which extends forward and has the same curvature as the arc-shaped movable plate, is fixedly connected to the inner end of the slider.

[0019] The radial movable baffle is frame-shaped and is slidably sleeved on the front end of the corresponding arc-shaped auxiliary plate. The radial movable baffle can be pulled outward or pushed inward as needed.

[0020] Preferred technical solution four: In order to realize the synchronous and opposite movement of the two sets of arc-shaped movable plates on both sides of the arc-shaped fixed plate, an adjustment component is provided on the worktable in the inner circle of the support frame.

[0021] Preferred technical solution five: The adjustment component includes an inner shaft rotatably mounted on the worktable and located at the center of the support frame, and a sleeve shaft rotatably mounted on the inner shaft, wherein the inner shaft is fixedly connected to a set of sliders and the sleeve shaft is fixedly connected to another set of sliders by a fixing rod.

[0022] The bottom ends of the inner shaft and the sleeve shaft extend to the bottom of the worktable, and a driving component is provided at the bottom of the worktable, which is connected to the inner shaft and the sleeve shaft to synchronously drive the inner shaft and the sleeve shaft to rotate in opposite directions.

[0023] (III) Technical Effects

[0024] The above structure gives this solution the following advantages:

[0025] 1. This utility model, by setting an arc-shaped fixed plate and an arc-shaped movable plate symmetrically slidably connected on both sides, can adjust the opening size according to the shape of the nanocrystalline magnetic core to be glued. It can adapt to both ring-shaped nanocrystalline magnetic cores and C-shaped nanocrystalline magnetic cores with different opening sizes, thereby improving the adaptability of the fixture, reducing the trouble of fixture replacement, and lowering production costs.

[0026] 2. The elastic protrusions achieve an interference fit with the inner ring of the nanocrystalline magnetic core, enhancing the positioning stability of the magnetic core on the fixture, preventing displacement of the magnetic core during dispensing, and improving dispensing accuracy.

[0027] 3. The radial movable baffle ensures that the front opening of the C-type nanocrystalline magnetic core is aligned with the front opening of the support frame when it is placed, avoiding misalignment and further ensuring the accuracy of the dispensing position. It can also be moved inward when it is used for toroidal magnetic cores without affecting their installation. Attached Figure Description

[0034] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0035] The nanocrystalline magnetic core dispensing support fixture of this utility model is described below with reference to the accompanying drawings.

[0036] Please see Figures 1-3 The nanocrystalline magnetic core dispensing support fixture of this utility model includes a worktable 1 and positioning mechanisms 2 distributed on the worktable 1, wherein:

[0037] The positioning mechanism 2 includes an arc-shaped fixed plate 21 and arc-shaped movable plates 22 symmetrically slidably connected to both sides of the arc-shaped fixed frame. Arc-shaped track grooves 211 are provided on both the left and right sides of the arc-shaped fixed plate 21. The sliders 222 with inward protrusions at the tail ends of the two sets of arc-shaped movable plates 22 extend into the two sets of arc-shaped track grooves 211 respectively. By sliding the sliders 222 back and forth along the arc-shaped track grooves 211, the size of the opening on the front side of the arc-shaped fixed plate 21 can be adjusted. When the opening is closed, it can be adapted to an annular nanocrystalline magnetic core. When the opening is reduced, it can be adapted to C-shaped nanocrystalline magnetic cores with different opening sizes.

[0038] Elastic protrusions 4 are embedded in the middle of the rear wall of the arc-shaped fixed plate 21 and the outer wall of the arc-shaped movable plate 22. The elastic protrusions 4 are made of rubber. When the nanocrystalline magnetic core is placed on the support frame, the elastic protrusions 4 deform to achieve an interference fit with the inner ring of the nanocrystalline magnetic core, thereby fixing the magnetic core in a stable position.

[0039] In one embodiment

[0040] Please see Figures 1-4A hole 221 is provided at the front end of the arc-shaped movable plate 22. The radial movable baffle 3 passes through the hole 221 and can move inward and outward along the radial direction of the support frame. An arc-shaped auxiliary plate 23 with the same curvature as the arc-shaped movable plate 22 is fixedly connected to the inner end of the slider 222. The radial movable baffle 3 is frame-shaped and is slidably sleeved on the front end of the corresponding arc-shaped auxiliary plate 23. A slide rod 24 is formed on the inner wall of the front end of the arc-shaped auxiliary plate 23 along the radial direction. The connecting hole on the rear wall of the radial movable baffle 3 is damped and slidably sleeved on the slide rod 24. When loading the C-type nanocrystalline magnetic core, the radial movable baffle 3 is pulled outward to move outward along the slide rod 24. The two sets of radial movable baffles 3 form a left and right shielding structure for the front opening of the support frame. The two end walls of the front opening of the C-type nanocrystalline magnetic core are in contact with the left and right shielding structures respectively to ensure the correct placement position. When targeting the annular nanocrystalline magnetic core, the radial movable baffle 3 is pushed inward to the inner side of the support frame to avoid obstructing the installation of the annular magnetic core.

[0041] In one embodiment

[0042] Please see Figures 3-4 An adjustment component 5 is installed on the workbench 1 within the inner ring of the support frame to achieve synchronous and opposite-direction movement of the two sets of arc-shaped movable plates 22. Specifically:

[0043] The adjustment assembly 5 includes an inner shaft 51 rotatably mounted on the worktable 1 and located at the center of the support frame, and a sleeve shaft 52 rotatably mounted on the inner shaft 51. The inner shaft 51 is fixed to a set of sliders 222, and the sleeve shaft 52 is fixed to another set of sliders 222 by a fixing rod 53. The bottom ends of the inner shaft 51 and the sleeve shaft 52 extend to the bottom of the worktable 1. A drive unit 6 is provided below the worktable 1 and is connected to the inner shaft 51 and the sleeve shaft 52.

[0044] The driving component 6 includes a first shank 61 fixed to the bottom end of the inner shaft 51 and a second shank 62 fixed to the bottom end of the sleeve shaft 52. The ends of the first shank 61 and the second shank 62 are both formed with parallel convex shafts 63. The driving component 6 also includes a base frame 64 fixed to the bottom side of the worktable 1. The base frame 64 is located in front of the inner shaft 51. A lead screw 65 is rotatably mounted in the base frame 64. The output shaft of the motor 66 mounted at one end of the base frame 64 is connected to the lead screw 65. In addition, the driving component 6 also includes a U-shaped frame 67. The middle part of the U-shaped frame 67 is slidably connected to the base frame 64 and threadedly connected to the lead screw 65 through a threaded hole. The rear ends of the two parallel sections of the U-shaped frame 67 are both fixed with horizontal rails 68. The two sets of convex shafts 63 extend into the two sets of horizontal rails 68 respectively and can slide along the horizontal rails 68.

[0045] When the size of the support frame opening needs to be adjusted, the motor 66 is started. The motor 66 drives the lead screw 65 to rotate. Since the U-shaped frame 67 is threadedly connected to the lead screw 65 and slidably connected to the base frame 64, the rotation of the lead screw 65 drives the U-shaped frame 67 to move back and forth. When the U-shaped frame 67 moves, the horizontal rails 68 at both ends pull the cam shaft 63 to swing back and forth. The longitudinal movement of the cam shaft 63 is consistent with the longitudinal movement of the U-shaped frame 67. At the same time, the lateral movement of the cam shaft 63 is the same as the lateral movement in the horizontal rail 68. The swing of the cam shaft 63 drives the cam handle 61 and cam handle 62 to rotate, which in turn causes the inner shaft 51 and the sleeve shaft 52 to rotate in opposite directions. Through the fixed rod 53, the two sets of sliders 222 slide synchronously in opposite directions along the arc-shaped track groove 211, thereby realizing the adjustment of the size of the support frame opening.

[0046] In use, according to the shape and size of the nanocrystalline magnetic core to be glued, the position of the arc-shaped movable plate 22 is adjusted by the above-mentioned adjustment component 5 to make the size of the support frame opening suitable; for C-type magnetic cores, the radial movable baffle 3 is pulled outward to position the magnetic core; then the magnetic core is placed on the support frame, and the elastic protrusion 4 achieves an interference fit to stabilize the magnetic core; then the glue dispensing operation can be performed.

[0047] During use, this solution requires daily maintenance of each component according to the established maintenance plan to ensure its working condition.

[0048] It is worth noting that the specific model of motor 66 mentioned in this embodiment, as well as its matching power supply and control switch, can also be provided by the manufacturer.
