Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core positioning, in particular to a magnetic core positioning fixture. Background Technique

[0002] The chip inductor, also known as power inductor, high-current inductor and surface-mounted high-power inductor, has the characteristics of miniaturization, high quality, high energy storage and low resistance. By adding a magnetic core to the magnetic strip, the magnetic force can be increased, and it mainly plays the role of filtering and oscillation in the circuit. In the past, when producing chip inductors, manual operation was used to neatly place the magnetic cores on the magnetic strip. At most, about 30 PCS magnetic cores can be placed on one magnetic strip. However, this production method has the following technical problems:

[0003] Manual operation leads to low production efficiency, slow speed, and limited number of magnetic cores loaded at one time. In addition, when manually placing the magnetic cores on the magnetic strip, due to the small size of the magnetic cores, the manual positioning accuracy is not high, which may lead to defects in product quality.

[0004] In summary, a magnetic core positioning fixture that can solve the above problems is proposed. Content of the Utility Model

[0005] To solve the technical problem of magnetic core positioning and feeding, the utility model provides a magnetic core positioning fixture.

Two pairs of clamps are arranged on the lower side of the positioning table. One pair of the clamps on each side is arranged in cooperation with the lower track plate. A hole array mechanism for positioning the magnetic cores in a matrix is arranged on the positioning table. A roller mechanism for facilitating the movement of the positioning table on the track plate is arranged between the track plate and the positioning table. A magnetic strip loading mechanism for loading magnetic strips is arranged on one side of the base.

[0007] As a further improvement of the above solution, the hole array mechanism includes a plurality of magnetic core positioning holes opened on the positioning table. The plurality of magnetic core positioning holes are distributed vertically and horizontally in a matrix. The aperture size of the magnetic core positioning holes is adapted to the radius of the magnetic cores. Each magnetic core positioning hole is used to place one magnetic core.

One side of the magnetic strip limiting platform is provided with a plurality of magnetic strip limiting grooves, and each magnetic strip limiting groove is used to place a magnetic strip. One side of the magnetic strip limiting platform is provided with a magnetic strip baffle mechanism for aligning and limiting a plurality of magnetic strips simultaneously.

[0010] As a further improvement of the above solution, the magnetic strip baffle mechanism includes a stop strip hinged to one side of the magnetic strip limiting platform.

[0021] Embodiment:

[0022] Please refer to Figure 1 - Figure 3 In this embodiment, a magnetic core positioning jig includes a base 1. Two sides of the base 1 are fixedly connected with track plates 5. Above the two track plates 5, a positioning table 2 is provided. The positioning table 2 has the same thickness as the magnetic core. The positioning table 2 is of a square structure and is made of a non-ferromagnetic metal material, such as an aluminum plate. If two handrails 3 are fixedly connected to both sides of the positioning table 2 respectively, it is convenient for subsequent workers to shake the positioning table 2 back and forth through the handrails 3. On the lower side of the positioning table 2, there are two pairs of clamps 15. Each clamp 15 is composed of a pair of clamping blocks, which form a resistance to the track plates 5 from both sides. When the positioning table 2 deviates during movement, it is beneficial to improve the positioning accuracy. A pair of clamps 15 on each side are arranged in cooperation with the track plates 5 below. On the positioning table 2, there is a hole array mechanism for positioning the magnetic cores in a matrix. Between the track plates 5 and the positioning table 2, there is a roller mechanism for facilitating the movement of the positioning table 2 on the track plates 5. On one side of the base 1, there is a magnetic strip loading mechanism for loading magnetic strips.

[0023] Please refer to Figure 1 As shown, the hole array mechanism includes 234 magnetic core positioning holes 4 opened on the positioning table 2, arranged in 18 longitudinal rows, with 13 magnetic core positioning holes 4 in each longitudinal row. The 234 magnetic core positioning holes 4 are distributed in a matrix vertically and horizontally. The aperture size of the magnetic core positioning holes 4 is adapted to the radius of the magnetic core. The magnetic core has a radius of about 3 mm, and each magnetic core positioning hole 4 is used to place one magnetic core.

[0024] Please refer to Figure 1 As shown, the roller mechanism includes track grooves 6 respectively opened on the two track plates 5, and a plurality of rollers 7 are rotatably connected to the inner sides of the two track grooves 6.

[0025] Please refer to Figure 1 As shown, the magnetic strip loading mechanism includes a magnetic strip limiting table 10 fixedly connected to the upper side of the base 1. The height of the magnetic strip limiting table 10 is flush with the lower side of the magnetic core positioning holes 4. On one side of the magnetic strip limiting table 10, there are 18 magnetic strip limiting grooves 11. In this embodiment, the magnetic strip limiting grooves 11 are strip-shaped and are changed accordingly according to the specific external configuration of the magnetic strip. Each magnetic strip limiting groove 11 is used to place one magnetic strip. On one side of the magnetic strip limiting table 10, there is a magnetic strip baffle mechanism for aligning and limiting 18 magnetic strips simultaneously.

[0026] Please refer to Figure 2 andFigure 1 As shown in the figure, the magnetic strip baffle mechanism includes a baffle strip 13 hinged to one side of the magnetic strip limiting table 10. A chuck 12 is fixedly connected to the lower side of one end of the baffle strip 13. The chuck 12 is of a hemispherical structure. An auxiliary chuck plate for facilitating the pushing force of the user is arranged on the upper side of the chuck 12. A connecting plate 8 is fixedly connected to the other side of the magnetic strip limiting table 10. A groove 9 is formed on the upper side of the connecting plate 8. The groove 9 is arranged in a paired manner with the chuck 12.

[0027] Please refer to Figure 2 As shown in the figure, a magnetic core hopper 14 is arranged on the upper side of the base 1. The magnetic core hopper 14 is located on one side of the magnetic strip limiting table 10. The magnetic core hopper 14 is arranged for placing magnetic cores, which is convenient for the staff to pick up the iron cores nearby.

[0028] The implementation principle of a magnetic core positioning jig in the embodiment of the present application is as follows: First, place the required miniature magnetic cores into the magnetic core hopper 14 and wait for feeding. After preparing the magnetic cores, slide the positioning table 2 to the track plate 5 above the magnetic core hopper 14. Then, insert multiple magnetic strips to be loaded with magnetic cores into the magnetic strip limiting grooves 11 on the magnetic strip limiting table 10 at one time. Then, close the baffle strip 13. At this time, the chuck 12 is inserted into the groove 9 of the connecting plate 8. Then, push the positioning table 2 back to directly above the magnetic strip limiting table 10. The staff picks up the magnetic cores pre-placed in the magnetic core hopper 14 onto the positioning table 2, and then frequently shakes the positioning table 2 left and right through the handrail 3 to make the magnetic cores fall into the array of magnetic core positioning holes 4. When all the magnetic core positioning holes 4 on the positioning table 2 are successfully loaded with magnetic cores, transfer the excess magnetic cores back to the magnetic core hopper 14, and then manually move the positioning table 2 upwards. At this time, due to the natural magnetic attraction of the magnetic cores and the magnetic strips, the linearly arrayed magnetic cores are respectively arranged on each magnetic strip.

[0029] The above implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present utility model belong to the protection scope required by the present utility model.
