[0061] like Figures 1 to 4 As shown, an embodiment of a coil wrapping method for a cylindrical component comprises the following steps:

[0062] S1, along the conveying direction of the coil, the coil is wound around the unwinding roller 2, a plurality of conveying rollers 4 and a cylindrical component in sequence;

[0064] S2, adjusting the output torque of the torque motor 3, and reading the torque measured by the torque sensor motor 7b, and calculating the tensioning force of the coiled material through the torque, so that the tensioning force reaches the preset tensioning force range of the coiled material;

[0065] In S2, the torque motor 3 is used to apply and gradually increase the output torque, and the torque reading of the torque sensor motor 7b is observed at the same time. The tensioning force is calculated based on the obtained torque reading. This tensioning force is the tensioning force when the coil is wrapped on the cylindrical component. When the tensioning force of the coil reaches the designed tensioning force, the torque motor 3 is stopped from being adjusted. The current output torque of the torque motor is the stall torque required for subsequent tensioning of the coil.

After applying glue on the coiled material behind the cylindrical member and the scraping mechanism 6, the glue is poured into the groove formed by the first table 5a and the second table 5b on the operating table 5, and when the coiled material passes through the gap, the glue is applied to the coiled material.

[0068] S4, the torque sensor type motor 7b drives the cylindrical member to rotate;

[0069] In S4, the U-shaped rod 74a is unplugged, and the torque sensor motor 7b is started to drive the cylindrical component to rotate. The coil is wrapped around its surface as the cylindrical component rotates. At this time, the torque motor 3 is in a stalled state, and the output shaft of the torque motor 3 is driven by the coil to rotate in the opposite direction, that is, it rotates in the opposite direction of the torque output direction of the torque motor 3.

[0070] S5, the glue scraping mechanism 6 scrapes the glue on the coil evenly;

[0073] In S6, when the coil wrapping of the cylindrical component is completed, a scoring knife is used to cut the coil along the scoring rail 8, and then the last section of the coil is manually pasted on the surface of the cylindrical component. Subsequently, the U-shaped rod 74a is inserted into the outer ring bearing 71a and the inner ring bearing 72a, and the handle 10 is rotated to release the abutment between the seat 9 and the cylindrical component, and the cylindrical component with the coil wrapping is taken out.

[0074] The working process of the present invention is as follows: first, the coil is wound on the unwinding roller 2, and the unwinding roller 2 can be removed by pulling out the pin 11 to remove the wound coil, or the torque motor 3 can be used to drive the unwinding roller 2 to rotate and wind the coil; then the U-shaped rod 74a is inserted into the outer ring bearing 71a and the inner ring bearing 72a, and then the handle 10 is rotated to make the screw rod 73a drive the support 9 to approach and clamp the cylindrical component; after the coil is wound around the unwinding roller 2 and the cylindrical component is fixed, the coil is then wound around the unwinding roller 2, multiple conveying rollers 4 and the cylindrical component in sequence according to the designed conveying route.

[0075] Then, the torque motor 3 is used to apply and gradually increase the output torque, and the torque degree in the torque sensor motor 7b is observed at the same time. The tensioning force is calculated based on the torque reading obtained. This tensioning force is the tensioning force when wrapping the coil on the cylindrical component. When the tensioning force of the coil reaches the designed tensioning force, the torque motor 3 is stopped from being adjusted. The current output torque of the torque motor is the stall torque required for subsequent tensioning of the coil.

[0076] Then, glue is evenly applied to the coiled material behind the cylindrical member and the glue scraping mechanism 6, and then the glue is poured into the groove formed by the first table 5a and the second table 5b on the operating table 5. When the coiled material passes through the gap, the glue is applied to the coiled material. Then, the U-shaped rod 74a is pulled out, and the torque sensor type motor 7b is started to drive the cylindrical member to rotate. The coiled material is transported and wrapped on its surface as the cylindrical member rotates.

[0077] When the coil passes through the scraper 6b, the scraper 6b evenly scrapes the glue on the surface of the coil, realizing the automatic gluing operation of the coil. When the coil wrapping of the cylindrical component is completed, the scraper is used to cut the coil through the scraper rail 8, and then the last section of the coil is manually pasted on the surface of the cylindrical component, and then the U-shaped rod 74a is inserted into the outer ring bearing 71a and the inner ring bearing 72a, and the handle 10 is rotated to release the contact between the seat 9 and the cylindrical component, and the cylindrical component after the coil wrapping is taken out.

[0078] In summary, the embodiment of the present invention provides a coil wrapping device and method for a cylindrical component, which clamps and fixes the cylindrical component through the adjustment part of the positioning structure and the torque sensor motor, and then winds the coil around the unwinding roller, multiple conveying rollers and the cylindrical component in sequence, and uses the torque sensor motor to drive the cylindrical component to rotate to drive the coil to be conveyed, so as to wrap the coil on the surface of the component. A torque motor is provided at the unwinding roller to apply torque to the coil, and the torque sensor motor measures the tensioning force of the coil on the cylindrical component, so that the tensioning force applied by the torque motor meets the requirements of the preset tensioning force, ensuring that the pasting quality of the coil meets the design requirements of the cylindrical component. Multiple conveying rollers are provided in the middle of the fixed frame to support and convey the coil, so that the coil can remain stable during the conveying process, avoiding problems such as uneven glue coating or loose wrapping caused by the shaking of the coil. An operating table is also provided on the fixed frame, and a glue scraping mechanism is provided on the upper part of the operating table. When the coil passes through the operating table, glue is coated on the coil. When passing through the glue scraping mechanism, the glue scraping mechanism evenly scrapes the glue on the coil to avoid glue accumulation or missing, thereby improving the adhesion between the coil and the cylindrical component.

[0079] In addition, the adjustment part in the positioning mechanism can adjust the clamping force to adapt the positioning mechanism to different cylindrical components, which improves the versatility and flexibility of the wrapping device. The knife rail is set in the middle of the fixed frame, which greatly simplifies the operation of cutting the coil; the scraper mechanism and the fixed frame are detachably connected by a fixing pin, which further simplifies the scraper replacement process; in addition, the output end of the torque motor is detachably connected to the unwinding roller by a latch, and the unwinding roller can be easily removed for coil installation, which further improves the simplicity of coil installation.

[0080] The embodiment of the present invention is simple and convenient to operate, with a high degree of automation, which not only improves work efficiency, but also saves a lot of manpower, avoids the influence of human factors on work quality, and solves the technical problems in the prior art that the process of wrapping wooden columns with carbon fiber cloth is complicated and inefficient, and it is difficult to control the tensioning force of the carbon fiber cloth during the wrapping process, and the pasting quality of the carbon fiber cloth cannot be guaranteed.

[0081] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
