Servo-controlled winding tension attenuation apparatus, winding machine and control method therefor

Abstract

The invention provides a servo-controlled winding tension attenuation apparatus, a winding machine and a control method therefor. The tension attenuation apparatus comprises a wire conveying mechanism and a wire pressing mechanism, wherein the wire conveying mechanism comprises a servo motor; the servo motor controls the wire pressing mechanism to move up and down; the wire pressing mechanism comprises a moving plate, a pressing block assembly and a front air cylinder and a back air cylinder; guiding holes are formed in the moving plate; the guiding holes are used for guiding varnished wires or insulating wires; and the front air cylinder and the back air cylinder drive the pressing block assembly to press the varnished wires or insulating wires tightly. The servo motor controls the wire pressing mechanism to move up and down, and the front air cylinder and the back air cylinder drive the pressing block assembly to press the varnished wires or insulating wires tightly, so that the magnitude of the tension of the varnished wires or insulating wires can be adjusted in order to satisfy process requirements of enabling the varnished wires or insulating wires to wind workpiece pins, and enabling the varnished wires or insulating wires to pass through framework wire-passing grooves; therefore, the magnitude of the tension of the varnished wires or insulating wires can be adjusted in the pin winding process in the fully automatic production; and in addition, the tension attenuation apparatus is simple in structure, and capable of improving the production efficiency and the product yield.

Description

technical field [0001] The invention relates to the field of automatic production, in particular to a servo-controlled winding tension attenuation device, a winding machine and a control method thereof. Background technique [0002] The multi-axis automatic winding machine is used to wind the enameled wire on the bobbin to form a coil. The coil is a component commonly used in the electronics industry. With the advancement of technology, the functions and control devices of the existing automatic winding machines have become more powerful and reliable. Compared with traditional winding machines, the performance is more outstanding, and the work efficiency has also been greatly improved. As a device that integrates a series of new technology applications such as numerical control, optoelectronics, and pneumatics, the complexity of the structure and functions of automatic winding machines is also increasing.

Problems solved by technology

[0004] However, when winding those enameled wire or insulated wire coils with relatively fragile skeletons, thinner stitches and thicker wire diameters, the tensioner cannot meet the needs of the above processes.

With the development of electronic components and their terminals in the direction of miniaturization, integration, and multi-function, the current required to pass through the coil is getting larger and larger, while the volume is getting smaller and smaller. The thicker and harder the diameter, the thicker the wire diameter, the greater the tension set by the tension attenuation device when winding the wire, so that the winding can meet the process requirements, and the greater the tension, the weaker the skeleton and the stitches will be It will not be able to bear it, and it will cause the skeleton to break or the pins to be skewed, resulting in scrap

At present, in many cases, it is necessary to use a multi-axis automatic winding machine to wind the wire, and then manually wind the stitches for production. The process of manually winding the stitches is easy to cause damage, which reduces the yield of production and greatly reduces the automation. production line efficiency, and increased production costs
