Description

Technical Field

[0001] The utility model belongs to the technical field related to electronic component production, and particularly relates to an automated precision winding die. Background Art

[0002] An inductor is an electronic component wound with a conductive material (usually copper wire) that uses the principle of electromagnetic induction to store and release energy. When current passes through a coil, a magnetic field is generated around it. The changes in this magnetic field generate a self-induced electromotive force in the coil according to Faraday's law of electromagnetic induction, which is the phenomenon of electromagnetic induction. The inductance of an inductor is a physical quantity that describes its self-induction capability. It is related to factors such as the number of turns of the coil, the winding method, the coil geometry, and the magnetic core material used in the coil. The inductor winding mold is a tool used to wind the coil during the inductor manufacturing process. It plays an important role in improving production efficiency and maintaining product quality, but it still has the following disadvantages in actual use:

[0003] When producing inductor coils, in order to produce inductor coils that meet dimensional requirements, the inductor coils need to be wound through dies of different diameters. However, when winding the inductor coils, changing the winding diameter requires disassembling and replacing the dies. Replacing the dies usually requires removing multiple screws, which is not convenient.

[0004] When a winding mold is used to produce an inductor coil, the end of the wire needs to be restricted by a limiting structure. When the end of the wire moves to the restricted position on the winding structure, the coil end needs to be clamped by an external structure. During further production, the non-contact structures need to cooperate with each other, which easily leads to dimensional errors. Utility Model Content

[0005] The purpose of this utility model is to provide an automated precision winding mold. By setting a servo motor, an electric push rod and a winding column, it solves the problem that when replacing the winding mold, multiple screws usually need to be removed, which is not convenient to disassemble, and additional equipment is required to clamp the wire end when producing inductor coils, which easily leads to dimensional errors.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model discloses an automated precision winding mold, comprising a servo motor, an electric push rod and a winding column, wherein one end of the servo motor is fixed with a reducer, the output end of the servo motor is fixed with the input end of the reducer, the output end of the reducer is fixed with a rotating disk, the rotating disk is away from the reducer and a rotating column is fixed, the outer side of the rotating column is sleeved with a positioning sleeve, the end of the positioning sleeve away from the rotating disk is fixed with a winding column, a movable plug block is fixed along the central axis of the positioning sleeve, the rotating column is provided with a movable socket along the central axis, the movable plug block is inserted into the movable socket, and an electric push rod is fixed on the rotating disk outside the positioning sleeve. When working, the power generated by the servo motor drives the reducer to work, and the reducer drives the turntable to rotate. The rotation of the turntable drives the electric push rod and the winding column to rotate, and the electric push rod pushes the pressing block to move when working, and the wire is wound into an inductor coil when the winding column rotates.

[0008] Furthermore, a support frame is commonly fixed at both ends of the servo motor, and the support frame is fixed on the outside of the reducer. The servo motor is supported at an external working position by the support frame.

[0009] Furthermore, a push rod is fixed to the telescopic end of the electric push rod, and one end of the push rod away from the electric push rod is fixed to the clamping block. When the electric push rod drives the push rod to move, the clamping block is pushed to be clamped with the clamping plate.

[0010] Furthermore, a fixing ring is fixed on the outside of the gap between the winding column and the positioning sleeve, and a movable opening is opened on the fixing ring corresponding to the position of the clamping block. The clamping block is movably connected in the movable opening, and a clamping plate is fixed on the circumference of the winding column corresponding to the position of the movable opening. The clamping block and the clamping plate abut against each other. When the winding column is working, the clamping block is movably connected through the movable opening on the fixing ring.

[0011] Furthermore, a threaded column is inserted through the middle of the peripheral side of the positioning sleeve, and a hexagonal socket is provided at one end of the threaded column close to the peripheral side of the positioning sleeve. The threaded column is movably connected to the hexagonal wrench through the hexagonal socket.

[0012] Furthermore, a screw hole is formed on the circumference of the rotating column, the screw hole is communicated with the movable socket, and the threaded column is threadedly connected in the screw hole. When the rotating column is working, it is threadedly connected to the threaded column through the screw hole.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that multiple screws need to be removed when replacing the winding mold, which is inconvenient to remove, by arranging a servo motor, an electric push rod and a winding column. When the winding column needs to be replaced, a hexagonal wrench is inserted into the hexagonal socket on the threaded column, and after unscrewing the threaded column, the winding column can be pulled to complete the separation between the winding column and the rotating column on the rotating disk. A suitable winding column is selected, combined with the rotating column, and then recombined with the threaded column to complete the mold replacement, making the operation of replacing the winding mold easier.

[0015] The utility model solves the problem that additional equipment is required to clamp the end of the wire, which is prone to dimensional error, when the winding mold produces the inductive coil by arranging a servo motor, an electric push rod and a winding column. When winding, the end of the wire is first moved from the wire outlet structure to between the clamping plate and the fixed ring, and then the electric push rod is started. The electric push rod drives the push rod to drive the clamping block to move, and the clamping block is pressed onto the wire and the clamping plate, so that the end of the wire is clamped. Then the servo motor is started to drive the reducer to work, and the reducer drives the rotating disk to rotate when it is working, and the rotation of the rotating disk drives the positioning sleeve and the winding column to rotate, and the wire is protruded through the structure of the output wire. After the wire is wound on the winding column with a suitable number of turns and spacing, the wire is cut by the external wire cutting structure to complete the winding of the inductive coil. During operation, the clamping structure of the wire end is directly arranged on the mold, which can conveniently and accurately limit the wire end. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiment 1

[0025] See also Figure 1-4 The utility model is an automated precision winding mold, comprising a servo motor 1, an electric push rod 2 and a winding post 3. A reducer 101 is fixed to one end of the servo motor 1. When the servo motor 1 is working, it generates power to drive the winding post 3 to rotate.

When the rotating disk 102 rotates, the electric push rod 2 and the winding post 3 are driven to rotate. A rotating column 103 is fixed to the end of the rotating disk 102 away from the reducer 101. The rotating column 103 provides an installation function for the positioning sleeve 302. The outer side of the column 103 is sleeved with a positioning sleeve 302, and a winding column 3 is fixed at the end of the positioning sleeve 302 away from the rotating disk 102.

The clamping block 202 is movably connected in the movable opening 304, and a clamping plate 305 is fixed on the side of the winding post 3 corresponding to the position of the movable opening 304. The clamping block 202 and the clamping plate 305 abut against each other.
