Description

Technical Field

[0001] The present invention belongs to the field of winding machines, and particularly relates to a high-efficiency square-hole continuous winding machine with switchable forward and reverse continuous winding. Background Art

[0002] In the current production field of continuously wound products of square flat coils, there are many limitations in the technical status quo. On the one hand, existing equipment can only wind products in a single direction, which means that in the production process, if products with different winding directions need to be produced, additional equipment must be equipped, greatly increasing production costs. On the other hand, in the single-machine production mode, the production efficiency of products is low and it is difficult to meet the growing market demand. This low production efficiency not only restricts the production capacity of enterprises, but also affects the economic benefits of enterprises to a certain extent. At the same time, due to the single function of the equipment, when changing products, equipment switching or adjustment is required, which consumes a lot of time and manpower, further reducing production efficiency and being unfavorable to the continuity and stability of production. These problems seriously restrict the development of the continuously wound product industry of square flat coils and urgently need a new technology or equipment to solve them.

[0048] Working principle:

[0049] Wire feeding preparation: The wire feeding mechanism and the rear wire feeding mechanism respectively send the flat copper wire to the material transfer mechanism and the rear material transfer mechanism. Before wire feeding, the operator will set parameters such as wire feeding length and speed according to production requirements to ensure that each wire feeding is accurate and error-free, providing wire materials of appropriate length for subsequent winding.

[0050] Wire pressing and winding: When the copper wire reaches the specified position, the wire pressing assembly acts quickly. Taking the wire pressing assembly of the material transfer mechanism as an example, components such as the support bottom plate and the race steel plate form a stable support structure. The wire pressing component, with the cooperation of floating joints, etc., tightly presses the flat copper wire to prevent it from displacing during the winding process. Motors in the front-end material transfer component and the rear-end material transfer component respectively drive the connecting shaft to drive the material transfer seat to rotate. The material transfer induction piece installed on the material transfer seat can accurately control the material transfer angle and the number of turns, realizing the bending and winding of the flat copper wire and making the coil according to the preset square specification.

[0051] Core-pulling assistance: During the winding process, the front-end core-pulling assembly and the rear-end core-pulling assembly play a crucial role. With the first cylinder and the second cylinder as the power sources, the cylinder shafts push the first core-pulling cylinder fixing plate and the second core-pulling cylinder fixing plate. Through the transmission of the first core-pulling lever and the second core-pulling lever, it drives the movement of components such as the first core-pulling lower rod and the second core-pulling lower rod. The first core-pulling pulling piece and the second core-pulling pulling piece act in coordination inside the guide plate, enabling the first core-pulling upper rod and the second core-pulling upper rod to perform precise core-pulling, ensuring that the coil is wound tightly and has a regular shape.

[0052] Stock support stability: The stock support mechanism is located at the rear end of the material transfer mechanism and always holds the coil during the entire winding process. Its special structural design can effectively prevent the coil from shaking too much due to factors such as centrifugal force generated during rotation during winding, ensuring the uniformity and stability of wire winding, and thus improving the product quality.

[0053] Wire cutting and transfer: When a coil winding is completed, the wire cutting mechanism starts to work. The wire cutting module on the wire cutting thickening plate provides an installation base for the wire cutting cylinder and the pushing cylinder. The wire cutting cylinder pushes the wire cutting module plate to slide, and the pushing cylinder controls the action of the pneumatic scissors through the wire clamping guide plate to precisely cut the wire. Subsequently, the wire pulling mechanism is activated to pull the wound finished coil from the material transfer mechanism or the rear-end material transfer mechanism to the next workstation, such as pulling it onto the assembly line mechanism for subsequent processing, inspection, or collection operations.

[0054] Multi-station coordination and direction switching: The multi-station combination is a major feature of this winding machine. Each mechanism works in coordination under the unified scheduling of the electrical control system to achieve continuous production. If it is necessary to switch between forward and reverse winding, the operator only needs to adjust the corresponding parameters in the control system, and components such as the wire feeding mechanism and the material transfer mechanism can quickly respond and change their working states to complete the winding of square coils in different directions on the same device without replacing the device, greatly improving the production efficiency and the convenience of the machine.

[0055] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those of ordinary skill in the relevant technical field can also make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention, and the patent protection scope of the present invention shall be defined by the claims.
