Description

Technical Field

[0001] The present application relates to the technical field of flexible mica composite coil production equipment, and in particular to an automatic laminating system for continuous production of flexible mica composite coils. Background Art

[0002] With the rapid development of new energy vehicles, consumers are paying more and more attention to the thermal runaway safety performance and NVH performance of the whole vehicle. The power lines in new energy vehicles are more dense than those in traditional gasoline vehicles, and the flame retardant safety performance of the wiring harness wrapping is required to be higher. A good wiring harness wrapping material can improve the NVH performance of the whole vehicle.

[0003] Traditional plastic cable ties as wire harness wrapping materials can only play a basic role in wire harness wrapping, and cannot effectively improve the thermal runaway safety performance and NVH performance of the vehicle, and can no longer meet the development needs of new energy vehicles. In recent years, the newly developed flexible mica wrapping tape as a wire harness wrapping material for new energy vehicles can not only play a role in wire harness wrapping, but also effectively improve its own flame retardancy and enhance the thermal runaway safety performance of the vehicle.

[0004] The existing flexible mica wrapping tape includes a flexible mica coil and an adhesive layer. The adhesive layer is compounded on the lower surface of the flexible mica coil. The adhesive layer generally adopts a flame retardant modified polyacrylate resin with good flame retardant properties or a silicone adhesive similar to the adhesive component in the flexible mica coil. It can play a good fixing and wrapping role for the connecting wire harness, has good flame retardancy as a whole, and improves the thermal runaway safety performance of the whole vehicle.

[0005] At present, there are two methods for mass production of flexible mica wrapped tapes. The first production method is to first produce a wide flexible mica coil, then coat the flexible mica coil with glue, and finally cut and roll up the coated flexible mica coil to obtain flexible mica wrapped tapes with different specifications such as a width of 0.8-2.4 mm.

[0006] The advantage of the first mass production method of flexible mica wrapped tape is that the cost of mass production is relatively low, but it requires the production enterprise to have the production capacity of large-width flexible mica coils, and also requires specific gluing equipment to complete the gluing operation, has certain requirements for the ring row, and the production cost is relatively high.

[0007] The second production method of the flexible mica wrapping tape uses conventional commercially available flexible mica paper as a base material, cuts the flexible mica paper into semi-finished flexible mica wrapping tapes of different specifications such as widths of 0.8-2.4 mm, and then compounds them with double-sided adhesive with flame retardant function to obtain finished flexible mica wrapping tapes.

[0008] The second mass production method of flexible mica wrapped tape is the current mainstream preparation process. The production cost is relatively low, the raw materials for production can be freely selected and combined, and the overall cost controllability is relatively better.

[0009] After the existing flexible mica wrapping tape was applied to new energy vehicles, automobile companies provided the following optimization suggestions: the flexible mica wrapping tape wrapped around the wiring harness will generate noise due to mutual friction, affecting the NVH performance and driving experience of the entire vehicle; in addition, friction will cause the mica powder on the surface of the flexible mica wrapping tape to fall off, affecting the battery cell environment, and it cannot be used for wrapping the battery cell module wiring of new energy vehicles. The battery cell module is the top priority of the vehicle's thermal runaway protection, which limits the application scope of the existing flexible mica wrapping tape.

[0010] To this end, the second generation of flexible mica wrapping tape was developed, and the first generation of flexible mica wrapping tape was compounded with flame retardant foam material, which not only meets the flame retardant safety performance, but also improves the sound insulation performance of the whole vehicle, and enhances the NVH performance and driving experience of the whole vehicle. The production method of the second generation of flexible mica wrapping tape requires that the flame retardant foam material be compounded on the upper surface of the flexible mica coil through a composite equipment, and the flame retardant foam tape and the first generation of flexible mica wrapping tape are unwound and placed on a composite roller for composite treatment, and finally rolled to obtain the second generation of flexible mica wrapping tape. In the production method of the above-mentioned second-generation flexible mica wrapped tape, at the same diameter, the length of the first-generation flexible mica wrapped tape is longer than the length of the flame retardant foam tape. After a roll of flame retardant foam tape is composited and consumed, it needs to be replaced with a new flame retardant foam tape in time. This production method requires manual operation to stop, change rolls, and start the machine, resulting in low production efficiency of the second-generation flexible mica wrapped tape, affecting the overall output and total production cost. Summary of the invention

When the flame-retardant conductive foam tape in a certain flame-retardant conductive foam tape unwinding unit 33 is completed, the driving motor 31 is turned on, and the guide roller group 4 is stopped at the same time, driving another flame-retardant conductive foam tape unwinding unit 33 to move and replace the flame-retardant conductive foam tape unwinding unit 33 that has completed the unwinding of the flame-retardant conductive foam tape, and the flame-retardant conductive foam tape unwinding unit 33 that has completed the unwinding of the flame-retardant conductive foam tape moves to the flame-retardant conductive foam tape unwinding unit disassembly area 302, and the flame-retardant conductive foam tape unwinding unit 33 that has completed the unwinding of the flame-retardant conductive foam tape is disassembled in the flame-retardant conductive foam tape unwinding unit disassembly area 302, and the disassembled flame-retardant conductive foam tape unwinding unit 33 that has completed the unwinding of the flame-retardant conductive foam tape is processed. The flame-retardant conductive foam tape is replaced to obtain a flame-retardant conductive foam tape unwinding unit 33 loaded with the flame-retardant conductive foam tape, and the flame-retardant conductive foam tape unwinding unit 33 loaded with the flame-retardant conductive foam tape is reloaded on the ball screw 32 in the flame-retardant conductive foam tape unwinding unit assembly area 301. The new flame-retardant conductive foam tape in the new flame-retardant conductive foam tape unwinding unit 33 after replacing the flame-retardant conductive foam tape unwinding unit 33 needs to be manually overlapped, and the first section of the new flame-retardant conductive foam tape is connected and fixed with the end of the previous section of the flame-retardant conductive foam tape by manual overlap. The guide roller group 4 is turned on, and after the flame-retardant conductive foam tape is overlapped, the flame-retardant conductive foam tape and the flexible mica tape are composited to produce the second-generation flexible mica composite coil.

[0059] refer to Figure 1When the flame retardant conductive foam tape in the flame retardant conductive foam tape unwinding unit 33 is changed (the time period from changing the roll to completing the manual overlapping), the brake roller group B in the guide roller group 4 limits the transmission of the flame retardant conductive foam tape, and the storage roller A221 and the storage roller B222 move in opposite directions, so that the distance between the storage roller A221 and the storage roller B222 becomes larger, and the flexible mica tape is stored between several storage unit roller groups 22.

[0060] refer to Figure 1 , the unwinding speed of the flexible mica tape in the flexible mica tape unwinding roller 1 is V1, the number of the storage unit roller group 22 in the flexible mica tape layer storage component 2 is n, and the movement speed of the storage unit roller group 22 is V2, , d is the diameter of the storage roller A221, and a is the distance between the central axis of the storage roller A221 and the central axis of the storage roller A221 in the initial state.

When the storage unit roller group 22 reaches the maximum storage capacity L for the flexible mica tape 极 After that, the flexible mica tape unwinding roller 1 stops, and the brake roller group A16 stops the flexible mica tape output by the flexible mica tape unwinding roller 1. The storage roller A221 and the storage roller B222 move toward each other to release the stored flexible mica tape. When the limit movement distance a+l1 of the storage roller A221 in the upper slide becomes the initial state distance a, the length of the released and stored flexible mica tape is L. 极 , the flexible mica tape unwinding roller 1 is turned on, and at the same time the brake roller group A16 releases the flexible mica tape output by the flexible mica tape unwinding roller 1, thereby ensuring the efficient production of the second-generation flexible mica composite coil.

[0062] refer to Figure 6 and Figure 7The specific structure of the flame retardant conductive foam tape unwinding unit 33 is as follows, which includes a toothed disc mainboard 331 and a flame retardant conductive foam tape unwinding roller group 332.

A stepper motor 333 is fixedly connected to the bottom of the housing 30, and the stepper motor 333 is used to drive the toothed disc mainboard 331 to rotate around its own axis. Specifically, the output shaft of the stepper motor 333 is coaxially fixedly connected to a driving gear 334 through a coupling, and the driving gear 334 is meshed with a driven gear 3340 meshed with the toothed disc mainboard 331. The driven gear 3340 is rotatably connected to a support rod, and the support rod is fixedly connected to the housing 30. The height of the top of the support rod relative to the ground is lower than the height of the bottom of the toothed disc mainboard 331 relative to the ground. When replacing the flame retardant conductive foam tape unwinding unit component 33 , the toothed disc main board 331 of the next flame retardant conductive foam tape unwinding unit component 33 needs to be meshed with the driven gear 3340 .

[0063] refer to Figure 6 and Figure 7 The toothed plate mainboard 331 is coaxially connected to the main rotating shaft 3311, and the main rotating shaft 3311 is fixedly connected to the supporting connecting member 330.

The first overlap joint of the flame-retardant conductive foam tape has glue, which can be detachably connected to the connector overlap roller 3323. When manually overlapping the flame-retardant conductive foam tape, the glue on the first overlap joint of the flame-retardant conductive foam tape is used as an adhesive to fix the first overlap joint of the flame-retardant conductive foam tape with the tail overlap joint of the previous flame-retardant conductive foam tape.

[0066] refer to Figure 6and Figure 7 In order to facilitate manual overlapping of the flame-retardant conductive foam tape, a flame-retardant conductive foam tape overlapping opening 300 is opened on the upper surface of the shell 30. Manual overlapping of the flame-retardant conductive foam tape operation brief description: When the flame-retardant conductive foam tape in the flame-retardant conductive foam tape unwinding assembly 3 is exhausted, the guide roller group 4 stops, the flame-retardant conductive foam tape stops transmitting, and the flame-retardant conductive foam tape on the flame-retardant conductive foam tape unwinding roller 3321 is replaced. The stepper motor 333 drives the toothed disc main board 331 to rotate 90 degrees, and a new flame-retardant conductive foam tape unwinding roller 3321 loaded with the flame-retardant conductive foam tape replaces the exhausted flame-retardant conductive foam tape.
