Description

Technical Field

[0001] This invention belongs to the field of winding machine technology, and relates to a winding machine structure, particularly a vertical winding machine structure. Background Technology

[0002] In the manufacturing process of electronic and electrical equipment such as motors, transformers, and inductors, coil winding is one of the core processes. Vertical winding machines are widely used in the mass production of various medium and large-sized coils due to their advantages such as high winding accuracy and wide compatibility with coil specifications.

[0003] Existing vertical winding machines typically consist of a frame and a winding device located inside the frame. The winding device uses a rotating fork in conjunction with the lifting of a die structure to achieve layer-by-layer tight winding of enameled wire onto the bobbin. In actual winding operations, after the coil is wound, hooking and cutting operations need to be performed. Although most vertical winding machines are equipped with hooking and cutting devices that have multi-directional movement capabilities and can perform basic hooking and cutting actions, the horizontal travel of these devices is mostly fixed. They cannot be flexibly adjusted according to coils with different inner and outer diameters, making it difficult to adapt to the hooking and cutting needs of coils of various specifications.

[0004] At the same time, some hook and cut wire devices also lack convenient adjustment structures for vertical movement, and the drive mode of the hook and cut wire components has a slow response speed and insufficient smoothness in the connection between hooking and cutting actions, which can easily lead to problems such as enameled wire slippage and incomplete cutting. This not only affects the processing quality of the coil, but also makes it difficult to match the high-speed and automated coil production cycle.

[0005] Therefore, how to develop a vertical winding machine structure with flexible horizontal and vertical stroke adjustment, strong adaptability, and high wire cutting efficiency to solve the above-mentioned technical defects of existing equipment has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a vertical winding machine structure. It solves the technical problem that traditional hook-and-cut wire devices have fixed horizontal and vertical travel strokes, making it difficult to adapt to coils of different specifications.

[0007] The objective of this invention can be achieved through the following technical solutions: A vertical winding machine structure includes a frame, a winding device is provided inside the frame, and a hook-and-cutting device that can move forward or backward toward the winding device is provided on one side of the winding device. The hook and cutter assembly includes an X-axis moving component, a Z-axis moving component, a Y-axis moving component, and a hook and cutter assembly.

The Y-axis moving component is connected to the sliding block two and the Z-axis moving travel is adaptively adjusted by the sliding block two to adapt to the winding of coils of different sizes. The Y-axis moving component includes a drive cylinder, and the hook-and-cutter assembly is connected to the push rod of the drive cylinder and is driven by the drive cylinder to reciprocate between two fixed positions in the Y-axis to improve moving efficiency.

[0008] In the above-mentioned vertical winding machine structure, the hook-and-cut device further includes a top plate, which is slidably connected to the top of the frame. The lead screw motor assembly is fixed on the frame and the slider of the lead screw motor assembly is fixed on the top plate. The Z-axis moving assembly is slidably connected to the bottom of the top plate.

[0009] In the above-mentioned vertical winding machine structure, the Z-axis moving component includes a mounting base, which is slidably connected to the top plate along the length direction of the top plate. The second lead screw motor assembly is fixed to the bottom of the top plate, and the second slider of the second lead screw motor assembly is fixed on the mounting base. The Y-axis moving component is mounted on the mounting base.

[0010] In the above-mentioned vertical winding machine structure, the mounting base is a square frame structure, the hook and cutter assembly is slidably connected to the inner side of the mounting base, and the drive cylinder is fixed to the top of the mounting base and its push rod is connected to the hook and cutter assembly.

[0011] In the above-mentioned vertical winding machine structure, linear guide rails are provided on both sides of the mounting base. The linear guide rails are arranged in a vertical direction. The hook-and-cut wire assembly includes a connecting seat. The two side plates of the connecting seat are respectively connected to the two linear guide rails. The main body of the hook-and-cut wire assembly is located inside the mounting base, which improves stability during rapid movement.

[0012] In the above-mentioned vertical winding machine structure, the drive cylinder is a double-stroke cylinder, which is suitable for various stroke requirements.

[0013] In the above-mentioned vertical winding machine structure, the hook-and-cut wire assembly includes a hook-and-cut wire arm and a rotary drive component. The end of the hook-and-cut wire arm has a hook groove and a wire-cutting clamp.

It has the following beneficial effects: 1. Flexible travel adjustment and strong adaptability The X-axis moving component of the wire hooking and cutting device adopts a first-stage adjustable-stroke lead screw motor assembly, and the Z-axis moving component adopts a second-stage adjustable-stroke lead screw motor assembly. The X-axis and Z-axis moving strokes can be flexibly adjusted respectively, which can accurately adapt to the wire hooking and cutting operations of coils with different inner diameters, outer diameters and heights. This greatly improves the versatility of the equipment, eliminates the need to replace the wire hooking and cutting mechanism with a special one for coils of different specifications, and reduces the production equipment cost and changeover and debugging time.

[0017] 2. High mobility, improving production cycle time. The Y-axis moving component uses a drive cylinder to move the hook and wire cutting component back and forth between two fixed positions. Compared with the traditional servo motor drive method, the cylinder has a faster response speed and more efficient action execution. At the same time, the drive cylinder is preferably a double-stroke cylinder, which can further adapt to various stroke requirements, speed up the connection rhythm of hooking and cutting actions, and help improve the overall production efficiency of coil winding.

[0018] 3. The structure is stable and reliable, ensuring processing quality. The mounting base of the Z-axis moving component adopts a square frame structure. The hook and cutter assembly is slidably connected to the inside of the mounting base through vertically arranged linear guide rails on both sides. During the movement, the force is evenly distributed and the stability is good, avoiding the hook and cutter arm from shifting or shaking. The hook and cutter arm is rotatably connected to the connecting base through bearings, and with the help of the rotary drive component, it can achieve a precise 180° rotation. The action accuracy of the hook groove and the cutter clamp is higher, effectively reducing problems such as enameled wire slippage and incomplete wire cutting, and ensuring the processing quality of the coil.

[0019] 4. The layout is compact and reasonable, facilitating maintenance. The screw motor assembly of the X-axis moving component is fixed on the frame, and the slider is connected to the top plate. The Z-axis moving component is slidably connected to the bottom of the top plate. The moving components are arranged in layers and have a compact structure, which saves equipment installation space and facilitates subsequent inspection and maintenance of components such as screw motors, cylinders, and linear guides, thereby reducing the operation and maintenance costs of the equipment.

The travel of the second slider 52 on the second lead screw motor component 51 is adjustable, and its adjustment method is the same as that of the first slider 42. Different height parameters are pre-stored through the control system of the second servo motor.

Its two side plates are slidably engaged with the two linear guide rails 54 by sliders. The main body of the hook and cutter assembly 7 is located inside the mounting base 53 to ensure the stability of the hook and cutter assembly 7 when moving in the vertical direction.

[0030] The hook-and-cut arm 71 is rotatably connected to the bottom of the connecting seat 73 via a bearing. The bearing is preferably a deep groove ball bearing, with its outer ring interference-fitted with the connecting seat 73 and its inner ring interference-fitted with the rotating shaft of the hook-and-cut arm 71. The rotation drive component 72 is a drive motor, which is fixed to the top of the connecting seat 73 via a motor mount.
