Technical Field

[0001] The utility model relates to the technical field of electronic component manufacturing, in particular to a feeding device for a magnetic core. Background Art

[0002] Coils in electronic devices come in a wide variety of sizes, especially in precision instruments, where the coils are very small and the magnetic cores inside them are even smaller. This places high demands on the assembly between the core and the coil. Conventional core assembly involves manually or mechanically placing the cores in a specific arrangement in a core box, which is then mechanically installed into the coil. However, due to the small size of the cores, assembling them into the box is labor-intensive and time-consuming. Utility Model Content

[0004] A push rod is provided on the left side of the silo, which is coaxial with the magnetic core in the V-groove of the sorting plate when it reaches the top dead center. The rear end of the push plate is connected to the piston rod of the cylinder through an adapter block; the cylinder is fixed on the frame.

[0005] In order to ensure that impurities or other magnetic cores higher than the magnetic core are removed, there are multiple air holes arranged at the same horizontal height.

[0006] In order to ensure that the magnetic core trapped in the V-shaped groove is not blown away, the maximum opening width of the V-shaped groove is greater than the diameter of the magnetic core.

[0007] The driving mechanism is a cylinder, a linear motor or a mechanical linear driving device; the mechanical linear driving device is a screw or rack driving structure.

[0008] The silo discharge port is connected to the feed pipe, and the feed pipe is arranged to be inclined downward.

[0013] The present invention will be described in detail below with reference to the accompanying drawings. As shown in the figure, the present invention includes a frame 16, on which a silo 3 is arranged, which is a right-angled triangle and includes a right-angled wall 32 and an inclined wall 31; a strip hole 33 is arranged between the lower side of the inclined wall and the right-angled wall, and the sorting plate 2 passes through the strip hole and is close to the right-angled wall; a V-shaped groove 21 is arranged above the sorting plate; the lower side of the sorting plate is connected to the output end of the driving mechanism; a horizontal air hole 5 is arranged at the upper end of the right-angled wall, and the air hole is connected to the high-pressure air source through the air pipe 11; the sorting plate is driven by the driving mechanism to move in the up and down directions, and the lower dead point is when the upper end 22 of the V-shaped groove moves to the strip hole to ensure that the sorting plate blocks the strip hole; the upper dead point is when the radial highest point 41 of the magnetic core in the V-shaped groove moves to the air hole height to ensure that the magnetic core exceeding the height of this point is blown away;

[0014] The left side frame of the silo is provided with a slide 13, on which a push rod 10 is provided. The push rod is coaxial with the magnetic core 4 in the V-shaped groove of the sorting plate when it reaches the top dead center. The rear end of the push plate is connected to the piston rod of the cylinder 8 through the adapter block 7; the cylinder is fixed on the frame. The "left side" here refers only to Figure 1 , is not intended to limit the scope of protection of the present utility model, but is only for clarity of expression.

[0015] In order to ensure that impurities or other magnetic cores higher than the magnetic core are removed, there are multiple air holes arranged at the same horizontal height.

[0016] In order to ensure that the magnetic core trapped in the V-shaped groove is not blown away, the maximum opening width of the V-shaped groove is greater than the diameter of the magnetic core.

[0017] The driving mechanism is a cylinder, a linear motor or a mechanical linear driving device; the mechanical linear driving device is a screw or rack driving structure. Such driving structures are well-known technologies and will not be described in detail here.

[0018] Preferably, the silo discharge port is connected to the feed pipe 12, and the feed pipe is arranged to be inclined downward.

[0019] The principle of the utility model is that when the sorting plate moves from bottom to top, some of the disorderly magnetic cores in the hopper are obviously in the V-grooves. As the sorting plate continues to rise, the magnetic cores not in the V-grooves will fall, while some of the magnetic cores obliquely embedded in the V-grooves will be blown away by the gas blown out of the air hole 5 at the top dead center. Finally, only the magnetic cores embedded in the V-grooves along the horizontal direction are left. The push rod at the upper end of the hopper pushes the various magnetic cores together and sends them to the conveying pipe. The conveying pipe is arranged to be inclined downward, thereby ensuring the automatic conveying of the magnetic cores in the lower process.
