Description

Technical Field

[0001] The utility model relates to the technical field of tape wrapping machines, and particularly relates to an automatic winding device for coil tape wrapping. Background Art

[0002] A coil tape wrapping machine is a special wrapping device for various coils, mainly used for the winding and processing of various types of coils in the electrical field. It can realize the full-automatic winding of insulating tape on the coil, which not only enhances the insulation performance of the coil, but also improves the overall stability and durability of the coil.

[0003] Most of the existing tape wrapping machines can only wrap the non-nose end of the coil, but cannot wrap the nose end part of the coil, resulting in great limitations in the use of the existing tape wrapping machines. At the same time, the wrapping head can adjust the tension of the insulating tape according to its own needs to avoid phenomena such as the loosening of the wound coil.

[0004] Therefore, the utility model provides an automatic winding device for coil tape wrapping to solve the above problems. Summary of the Utility Model

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an automatic winding device for coil tape wrapping to solve the problems of being applicable to various curved coils and rotary coils and being able to independently control the tension of the insulating tape.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An automatic winding device for coil tape wrapping includes a base, on the upper part of which a robotic arm control seat is slidably connected. At the top of the robotic arm control seat, a six-axis robotic arm is provided. At the output end of the six-axis robotic arm, a wrapping head is installed. The wrapping head has an annular structure with one side open. On the inner wall of the wrapping head, a rotating ring is rotatably connected. On the inner side wall of the rotating ring, a tape reel assembly, a guide rod assembly, and a balance disk are sequentially and fixedly installed. This device can, through the mutual cooperation of the base and the six-axis robotic arm, enable the wrapping head to move and maintain its posture. At the same time, the rotating wrapping head can be displaced through the base, realizing that this device can automatically perform the wrapping of coils with different shapes and sizes, so that this device can be applicable to the tape wrapping of various coils with different bending degrees and rotary coils.

[0008] Preferably, the tape reel assembly includes a fixed seat and a tape reel seat. The tape reel seat is rotatably connected to the fixed seat. A fixing bolt is installed at the center of the tape reel seat. On the surface of the tape reel seat, a clamping block is provided. The clamping block is flexible. The number of the clamping blocks is multiple, and the multiple clamping blocks are uniformly arranged along the circumferential direction of the fixing bolt.

[0009] Preferably, a first thrust bearing, a compression spring, and a second thrust bearing are sequentially installed on the outer wall of the fixing bolt and above the belt disc seat. The bottom of the fixing bolt passes through the center of the belt disc seat, and a friction disc is installed at the center of the lower part of the belt disc seat where the fixing bolt is located. The bottom of the friction disc is slidably abutted against the upper part of the fixing seat.

[0010] Preferably, a tensioning core is clamped inside the clamping block, and protrusions are arranged radially along the outer ring of the tensioning core. When the device is in use, the wrapping head is controlled to rotate by a six-axis robotic arm. At the same time, under the action of the robotic arm control seat and the base, the six-axis robotic arm is driven to displace, realizing diverse tape wrapping. When installing the insulating tape, first, the inner ring of the insulating tape is clamped on the outer wall of the clamping block, and then by installing the tensioning core, the tensioning core rotates, enabling the protrusions on the tensioning core to tighten the inner hole of the insulating tape, achieving the function of restricting the insulating tape, thereby realizing the fixation of the insulating tape. At the same time, when the tensioning core of the device is installed, through rotational limiting and a slow increase in diameter, the belt disc seat of the device can be suitable for the use and installation of insulating tapes with various different diameters. When it is necessary to control the tension, by rotating the fixing bolt to squeeze the compression spring, the friction force between the friction disc and the fixing seat is changed, realizing the control of the tension of the insulating tape.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. Through the mutual cooperation of the base and the six-axis robotic arm, the device can make the wrapping head move and maintain its posture. At the same time, the rotating wrapping head can be displaced through the base, enabling the device to automatically wrap different-shaped and sized coils, making the device suitable for wrapping tapes around coils with various bending degrees and rotary coils.

[0013] 2. When the tensioning core of the device is installed, through rotational limiting and a slow increase in diameter, the belt disc seat of the device can be suitable for the use and installation of insulating tapes with various different diameters. When it is necessary to control the tension, by rotating the fixing bolt to squeeze the compression spring, the friction force between the friction disc and the fixing seat is changed, realizing the control of the tension of the insulating tape.

When installing the insulating tape, first, the inner circle of the insulating tape is clamped on the outer wall of the clamping block 63, and then by installing the tensioning core 9, the tensioning core 9 rotates, realizing that the protrusions on the tensioning core 9 tighten the inner hole of the insulating tape, achieving the function of limiting the insulating tape, thereby realizing the fixation of the insulating tape. At the same time, when the tensioning core 9 of the device is installed, through rotational limiting and a slow increase in diameter, the tape reel seat 62 of the device can be suitable for the use and installation of insulating tapes with various different diameters. When it is necessary to control the tension, by rotating the fixing bolt to squeeze the compression spring, the friction force between the friction disc and the fixing seat is changed, realizing the control of the tension of the insulating tape.
