Description

Technical Field

[0001] The present invention relates to the technical field of magnetic core winding equipment, and in particular to a winding equipment for I-shaped magnetic cores and a winding method thereof. Background Art

[0002] Inductors are common electronic components in circuits, which mainly play roles such as filtering, oscillation, delay, and notch filtering in circuits. They also have functions such as signal screening, noise filtering, current stabilization, and suppression of electromagnetic wave interference, so they are widely used. I-shaped inductors are mostly two-legged or three-legged I-shaped inductors, and their induction coils are usually wound on magnetic cores.

[0003] Traditionally, winding the coil skeleton is generally operated manually. Manual winding not only has a slow speed, but also leads to high labor intensity and high labor costs for workers. Later, some semi-automatic winding machines appeared on the market. Although these winding machines can achieve automation in some winding steps, many processes still need to be completed manually, with high labor intensity, low work efficiency, and long production cycles, which are not suitable for large-scale production of enterprises. Moreover, the winding effect cannot be guaranteed, resulting in high production costs and being unfavorable to the long-term development of enterprises. Therefore, how to solve the above technical problems is an urgent technical problem in the industry. Summary of the Invention

[0025] The wire winding method of the I-shaped magnetic core winding equipment includes the following steps:

[0026] First, material feeding and material distribution: The vibrating disk holds the magnetic cores to be wound. The magnetic cores are fed by the vibrating conveyor line and distributed by the material distribution screw driving assembly, and enter the material distribution line in rows of ten.

[0027] Second, double-spindle feeding: The magnetic cores on the material distribution line are moved by the transfer rack to the material holding seat of the main spindle feeding device. One of the material holding seats slides along the guide rail to the lower part of the wire winding mechanism.

[0028] Third, winding, wire hanging, and wire cutting: The left wire clamping component of the winding mechanism clamps one end of the wire, and the right wire clamping component clamps the other end of the wire. The winding column rotates to drive the wire to wind around the magnetic core. While the winding column rotates, the magnetic core also rotates, but the rotation speed of the magnetic core is less than that of the winding column. After the wire is wound around the magnetic core, the left wire clamping component and the right wire clamping component simultaneously pull both ends of the wire to hang the wire on the other side of the magnetic core. After the wire is fixed on the magnetic core, the wire cutting component moves upward, and at the same time, the tool head extends forward to cut off the excess wire after hanging the wire. The magnetic core after wire cutting returns to its original position with the material holding seat.

At the same time, another material holding seat slides to the lower part of the winding mechanism for winding operation.

[0030] Fifth, preheating: The transfer rack moves the magnetic core after applying solder flux to the preheating mechanism for preheating treatment.

[0031] Sixth, tin dipping: The transfer rack moves the preheated magnetic core to the tin bath for tin dipping operation.

[0032] Seventh, tin scraping: The tin scraping wire moves to scrape off the tin tips on the wire.

[0033] Eighth, flattening: Flatten the electrode surface after tin dipping.

[0034] Ninth, discharging: The transfer rack transfers the magnetic core after flattening treatment to the discharging mechanism, and it is discharged from the discharging port.

[0035] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions, by centrally arranging the vibration feeding and material separating mechanism, double-spindle feeding mechanism, winding mechanism, solder flux directional coating mechanism, preheating mechanism, flattening mechanism, tin dipping mechanism, tin dipping and tin scraping device, and discharging mechanism on the frame to form a winding device for I-shaped magnetic cores, this winding device has the following characteristics:

[0036] First, the double-spindle feeding mechanism can feed materials alternately, improving the feeding efficiency, and at the same time improving the overall utilization rate of the equipment, enabling the equipment efficiency to be fully exerted and improving the processing efficiency of products.

[0037] Second, the winding mechanism adopts the coordinated cooperation of the left wire clamping component, right wire clamping component, winding component, and wire cutting component, enabling winding, wire hanging, and wire cutting to be carried out quickly and continuously, improving the processing efficiency of products. At the same time, the overall structure is compact, completely replacing manual labor, and having a high degree of automation.

[0038] Third, the tin dipping and tin scraping device uses a connecting rod drive to quickly convert the torque of the motor into linear movement, with a fast transmission action speed, a fast moving speed, high precision, and the tin scraping depth can be finely adjusted to microns, and the scale is highly controllable.

[0039] Fourth, the same motor can drive the tin scraping line and the material sucking and flipping mechanism to rotate synchronously at the same time, maximizing the efficiency of the motor, saving energy consumption and reducing costs.

[0040] Fifth, the overall structure of the tin dipping and scraping device is compact, the actions are coherent and fast, and the coordination and effectiveness of the cooperation of each mechanism are fully exerted.

[0145] Third, winding, wire hanging, and wire cutting: The left wire clamping component of the winding mechanism clamps one end of the wire, and the right wire clamping component clamps the other end of the wire. The winding column rotates to drive the wire to wind around the magnetic core.

This winding device has the following characteristics:

[0153] First, the double-spindle feeding mechanism can alternate feeding, which improves the feeding efficiency. At the same time, it improves the overall utilization rate of the equipment, enables the full play of the equipment efficiency, and improves the processing efficiency of products.

[0154] Second, the winding mechanism adopts the coordinated cooperation of a left wire clamping component, a right wire clamping component, a winding component, and a wire cutting component, enabling the winding, wire hanging, and wire cutting to be carried out quickly and continuously, improving the processing efficiency of products. At the same time, the overall structure is compact, completely replacing manual labor, and having a high degree of automation.

[0155] Third, the tin dipping and scraping device driven by a connecting rod can quickly convert the torque of the motor into linear movement, with a fast transmission action speed, a fast moving speed, high precision, and the tin scraping depth can be finely adjusted to micrometers, and the scale controllability is strong.

[0156] Fourth, the same motor can drive the tin scraping line and the material sucking and flipping mechanism to rotate synchronously at the same time, maximizing the efficiency of the motor, saving energy consumption and reducing costs.
