Description

Technical Field

[0001] The present invention relates to the technical field of circular component metallized film processing, and in particular to a winding tension device and method for circular component metallized film on-site in a workshop. Background Art

[0002] High-performance film capacitors are widely used in fields such as flexible DC transmission projects, rail transit, new energy vehicles, medical treatment equipment, and electromagnetic pulse weapons. Among them, DC-link capacitors (dry-type DC support capacitors) are even more important equipment in flexible DC transmission projects and are extremely critical devices in the converter valve. Due to reasons such as limited space in the converter valve hall, DC-link capacitors are dry-type metallized film capacitors, and the internal core is composed of several circular components. The circular components are wound by polypropylene film (hereinafter referred to as metallized film) with surface metallization. The thickness of the insulating dielectric layer of the metallized film is generally 6-12 microns, and the thickness of the zinc-aluminum layer evaporated on the surface is generally several nanometers. This process enables the metallized film to have excellent "self-healing performance". The "self-healing performance" refers to the ability of the zinc-aluminum layer at the breakdown position to quickly evaporate under the action of a short-term discharge current when the insulating dielectric breaks down, and the breakdown position recovers insulation, so as to isolate the damaged area of the dielectric and allow the other intact dielectric parts to continue to work normally. The "self-healing performance" is the most critical index of the metallized film capacitor, and directly determines the operation safety and service life of the DC-link capacitor. The pressure between the film layers of the circular component is one of the key factors affecting the "self-healing performance", and the pressure between the film layers is determined by the winding tension of the circular component metallized film. Therefore, the accurate control of the metallized film winding tension is one of the key process points in the production of DC-link capacitors. The circular components are wound by a capacitor winding machine. Currently, the known winding tension of the metallized film is preset by the winding machine manufacturer before leaving the factory, and the capacitor manufacturer inputs the winding tension on the touch screen of the winding machine.

[0003] According to the patent published on the Chinese Patent Network, the patent name is: An Automatic Winding Device for Metallized Films, and the patent application number is: 202021699785.3. It includes a base, on the top of which a base frame is fixedly connected. An inlet roller is installed on the left side of the base frame, and a metallized film is installed inside the inlet roller. A support column is fixedly connected to the top of the base and is located on the right side of the inlet roller. On both the left and right sides of the top of the support column, connecting blocks b are fixedly connected. A support rod is fixedly connected to the top of the base and is located on the right side of the support column. A film-wrapping roller is fixedly installed at the top of the support rod, and a metallized film is installed on the surface of the film-wrapping roller; the automatic winding device of the present invention has a structure for maintaining tension during winding, so that the metallized film can be wound while maintaining tension and the winding effect and quality can be better. At the same time, the automatic winding device has a structure for cleaning ash, so that the wound metallized film can be kept clean to a certain extent; while the above-mentioned winding tension device can only rely entirely on the tension preset program of the winding machine manufacturer and cannot change the tension according to the lack of "calibration" or "calibration" on the workshop site, which leads to the inability to adapt to the tension required by metallized films with different production requirements and affects its processing quality.

[0004] Therefore, it is necessary to design and transform the winding tension device to effectively prevent the phenomenon that it cannot adjust the tension on the workshop site. Summary of the Invention

[0018] As a preferred usage method of the present invention, it includes the following steps:

[0019] S1: First, when the operator needs to adjust the tension, the motor is started. The output end of the motor drives the screw to rotate. The screw drives the nut block to move upward.

Then the concave plate and the brush pad are limited, so as to achieve the effect of disassembling and replacing the brush pad.

The buffer plate drives the abutting rod to move upward, so that the abutting rod abuts tightly inside the convex block, achieving the effect of limiting the toothed plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The winding tension device of the present invention changes the traditional phenomenon that the tension cannot be changed according to the lack of "calibration" or "adjustment" on-site in the workshop.

[0025] 2. Through the setting of the cleaning mechanism, the present invention can clean the top of the transmission component to avoid the phenomenon of dust accumulation.

[0026] 3. Through the setting of the disassembly and assembly mechanism, the present invention can easily disassemble the brush pad to avoid the phenomenon that the brush pad is contaminated with a lot of dust after excessive wiping, which affects the next use.

6. A winding tension device for a circular component metallized film at a workshop site according to claim 2, characterized in that: A chute (36) is formed in the front of the sliding plate (19). The back of the toothed plate (18) is slidably connected to the inside of the chute (36).

7. The winding tension device for the metallized film of circular components on the workshop site according to claim 3, wherein: Grooves (37) are formed in both the front side and the rear side of the outer side of the top of the cleaning plate (21). The bottom of the L-shaped baffle (27) is slidably connected to the inside of the groove (37).

8. A method for using a winding tension device for a circular component metallized film in a workshop site according to any one of the above claims, characterized in that: It includes the following steps: S1: First, when the operator needs to adjust the tension, the motor (8) is started. The output end of the motor (8) drives the screw rod (9) to rotate. The screw rod (9) drives the nut block (10) to move upward. The nut block (10) drives the special-shaped plate one (11) to move upward. The special-shaped plate one (11) drives the connecting plate one (12) to move upward. The connecting plate one (12) drives the connecting plate two (13) to move upward. The connecting plate two (13) drives the lower rod (14) to move upward. The lower rod (14) drives the convex rod (15) and the winding roller (3) to move upward, so as to adjust the tension of the winding roller (3). After the tension is adjusted, the data is transmitted to the calibrator (38) through the data connection line, and then compared with the standard tension value set in advance in the calibrator (38) to ensure that the error is within the allowable range, so as to achieve the effect of calibrating or adjusting the tension on the workshop site; S2: Then, while the screw rod (9) rotates, the toothed ring (17) also rotates accordingly. The toothed ring (17) drives the toothed plate (18) to move forward. The toothed plate (18) drives the special-shaped plate two (20) to move forward. The special-shaped plate two (20) drives the cleaning plate (21) and the brush pad (22) to move forward, so that the brush pad (22) cleans the dust on the top of the transmission assembly (4), so as to achieve the effect of cleaning the transmission assembly (4). S3: When the brush pad (22) needs to be replaced, pull the L-shaped baffle (27) outward to separate the L-shaped baffle (27) from the moving plate (24). Then, after the moving plate (24) is no longer blocked by the L-shaped baffle (27), the first spring (25) will rebound. The first spring (25) drives the moving plate (24) and the concave plate (26) to move outward, separating the concave plate (26) from the brush pad (22). Then, remove the brush pad (22) for replacement, and then perform a limiting process on the concave plate (26) and the brush pad (22), so as to achieve the effect of being able to disassemble and replace the brush pad (22). S4: When the toothed plate (18) does not need to move, the resilience of the second spring (32) drives the buffer plate (33) to move upward. The buffer plate (33) drives the abutting rod (34) to move upward, so that the abutting rod (34) abuts tightly inside the convex block (29), achieving the effect of being able to limit the toothed plate (18).
