Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and in particular to a capacitor core winding device. Background Technology

[0002] Traditional capacitor cores have a fixed insulation film width, and winding equipment can only accommodate films of fixed specifications. However, as capacitor products become more multifunctional and customized, some designs require the insulation film width to change according to specific rules (such as gradual or segmented adjustments) during winding to meet the needs of different electrical performance parameters or structural dimensions. Traditional equipment lacks a dynamic cutting mechanism, making it impossible to achieve regular adjustments to the insulation film width. Manual cutting is not only inefficient but also leads to unstable film tension and poor winding accuracy, severely affecting the consistency of core quality.

[0003] Furthermore, existing winding equipment generally suffers from insufficient automation when facing winding requirements with variable widths. When the base film needs to be cut, traditional processes struggle to synchronize the cutting action with the winding process, and lack an automatic waste collection mechanism, resulting in waste accumulation and significant material waste on the production floor, failing to meet the requirements of modern, efficient production.

[0009] 1. This utility model provides a capacitor core winding device that, through a preset program in the control system, drives the scalpel of an automatic cutting device to a designated position, enabling precise cutting of the insulating film according to product design requirements and achieving specified variations in film width. Compared to traditional fixed-width winding equipment, this device can flexibly adapt to the production of capacitor cores of different specifications, meet diverse design requirements, and avoid the errors and inefficiencies of manual adjustments.

[0010] 2. The capacitor core winding device provided by this utility model allows for the following process: after the material shaft releases the film, the tension is adjusted and the film is flattened through the shaft assembly to ensure uniform tension and a smooth surface during film conveying; the main shaft winds the film to a specified number of turns under the control of a stepper motor; combined with the real-time monitoring of winding parameters by the control system, the number of turns and arrangement of the insulating film on the fittings can be controlled, ensuring that the structural parameters of the capacitor core (such as thickness and density) strictly meet the design standards, thereby improving product consistency and electrical performance stability.

[0017] Combination Figure 1 and Figure 2As shown, a capacitor core winding device of this utility model includes a base 1 and a super-flat plate 2. The super-flat plate 2 is fixed on the top of the base 1. A main shaft 7 is provided on the super-flat plate 2. Three sets of material shafts 3 are provided on one side of the main shaft 7. A cross-shaft assembly 4 is provided between the material shafts 3 and the main shaft 7.

[0018] There are four sets of through-shaft assembly 4, and the four sets of through-shaft assembly 4 are equally spaced on the hyperplane plate 2.

[0019] A cutting device 5 is provided on the top of one of the shaft assembly 4, and a scrap shaft 6 is provided between the shaft assembly 4 and the main shaft 7.

[0020] Specifically,

[0021] Material shaft 3, waste material shaft 6 and main shaft 7 are all controlled to rotate by motors.

[0022] Material shaft 3 adopts a keyed air expansion shaft. By applying positive pressure gas to the air bladder of material shaft 3, the insulating film tube is quickly fixed on material shaft 3. The device is also equipped with an automatic brake. During the winding process, the tension of the film can be adjusted by adjusting the brake of material shaft 3.

[0023] The over-shaft assembly 4 is used to adjust the tension of the membrane, flattening the insulating membrane and ensuring an effective transition.

[0024] According to the needs of the product's insulating film, the position of the cutting blade on the cutting device 5 is automatically adjusted to cut the capacitor film that is being wound, without affecting the strength of the film itself.

[0025] The scrap shaft 6 winds the edge material cut off by the cutting device 5 to prevent the film from affecting the product on the main shaft 7 during the winding process.

[0026] The spindle 7 is controlled by a stepper motor. The insulating film is wound onto the hardware of the spindle 7 in a specified number of turns.

[0027] The control system uses programmable control technology to drive and monitor the motor and cutting position.

[0028] Working principle:

[0029] First, the insulating film tube is installed on the material shaft 3 and fixed by inflating it with an air shaft.

[0030] The material shaft 3 rotates to release the membrane material, which is then adjusted for tension and flattened by the shaft assembly 4 before being conveyed toward the main shaft 7.

[0031] According to the preset program, the control system drives the scalpel of the automatic cutting device 5 to move to the designated position to cut the membrane material and change the width of the insulating film.

[0032] The scrap material generated during cutting is simultaneously wound and collected by the scrap shaft 6.

[0033] Under the control of a stepper motor, the spindle 7 winds the cut insulating film onto the hardware in a specified number of turns to form the capacitor core.

[0034] Throughout the process, the control system continuously monitors the operating status of each component to ensure that the width variation pattern and winding parameters are executed accurately.
