Description

Technical Field

[0001] This utility model relates to the technical field of tape application equipment, specifically a tape application head used for automated protection of aerospace parts. Background Technology

[0002] In the manufacturing and maintenance of aero-engines, disc-ring parts require the application of high-temperature resistant tape before painting or heat treatment to prevent small particles from entering the internal cavities or gaps of the parts, thus affecting their performance and service life. Traditional tape application relies heavily on manual labor; the tape cutting and winding process is cumbersome, resulting in low efficiency, difficulty in meeting the demands of mass production, and low automation. Furthermore, the labor intensity is high, and the tape application process is prone to air bubbles, wrinkles, or poor adhesion, leading to protective failure and difficulty in guaranteeing adhesion accuracy, thus affecting the protective effect.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

Detailed Implementation

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0021] Please see Figure 1-4 A tape applicator for automated protection of aerospace parts includes an adhesive backing plate 1, a mechanical connection structure mounted on the adhesive backing plate 1, an unwinding structure mounted on the adhesive backing plate 1, a paper-free winding structure on the adhesive backing plate 1 and located on one side of the unwinding structure, a shearing structure on the adhesive backing plate 1 and located on the other side of the unwinding structure, and a pressing structure at the bottom of the adhesive backing plate 1.

[0022] Specifically, the mechanical connection structure includes a robot connector 19, which is installed on the top of the adhesive backing plate 1, and a terminal quick-change disc connecting shaft 20 is installed on the robot connector 19.

[0023] It should be noted that the device is connected to the power supply and control system. The robot connector 19 is used to connect the adhesive backing plate 1 and the terminal quick-change plate connecting shaft 20. The terminal quick-change plate connecting shaft 20 is used to connect to the robot's robotic arm. The device can use a set of control systems with the robot. Since this is existing technology, it will not be described in detail here. The unwinding structure is used to install the heat protection tape. The paper-free winding structure is used to wind up the backing paper peeled off the heat protection tape. The cutting structure is used to cut the tape after the heat protection tape is applied. The pressing structure is used to press the tape flat and bubble-free onto the surface of the aerospace parts.

[0024] Specifically, the unwinding structure includes a central shaft 2, which is movably inserted into the upper center of the adhesive backing plate 1 via the central shaft 2 support. A magnetic damper 4 is mounted on the central shaft 2 and is fixedly installed on the adhesive backing plate 1. A material tray 5 is fixedly mounted on the central shaft 2. Preferably, further, multiple pressure strips 22 are embedded in a circular array on the outer wall of the material tray 5, and each pressure strip 22 has a spring block 23 movably inserted through a spring 24. Preferably, further, multiple guide wheels 21 are movably inserted on the adhesive backing plate 1.

[0025] It should be noted that the rolled high-temperature resistant tape is installed on the material tray 5, and the pressure strip 22 is used to install the spring 24. The rolled high-temperature resistant tape squeezes the spring block 23, and the spring 24 is compressed. The spring 24 abuts against the inner ring of the rolled high-temperature resistant tape by the elastic force of the spring 24, which restricts the radial and axial movement of the rolled high-temperature resistant tape and achieves the fixation of the rolled high-temperature resistant tape.

[0026] After the tape is drawn out from the tray 5, it is guided by multiple guide wheels 21 set on the adhesive back plate 1 to form a conveying path for the tape to be pasted. When pasting the tape, the rolled high-temperature resistant tape drives the tray 5 and the central shaft 2 to rotate. The magnetic damper 4 can continuously provide resistance torque to keep the tape in a proper tension state during the conveying process, avoiding looseness or excessive stretching.

[0027] Specifically, the paper-free winding structure includes a winding motor 6, which is mounted on the adhesive backing plate 1. The drive end of the winding motor 6 is movably inserted into the adhesive backing plate 1. A separation bushing 7 is fixedly fitted on the drive end of the winding motor 6. A notch 8 is provided on the separation bushing 7. A separation material roller core 9 is movably inserted into the center of the separation bushing 7. A paper-free pressure plate fixing seat 10 is installed on the adhesive backing plate 1 and below the separation bushing 7.

[0028] It should be noted that during the tape application process, the backing paper on the back of the tape is peeled off. One end of the peeled backing paper enters between the separating bushing 7 and the separating material roller core 9 through the notch 8. By rotating the separating material roller core 9, one end of the backing paper is fixed. When the device performs tape application, the winding motor 6 starts to work, so that the peeled backing paper is wound on the separating bushing 7, realizing the automatic recycling of the tape backing paper. The paper release plate fixing seat 10 is used to press and tension the separating paper to ensure that it will not loosen, pile up or wrinkle during the winding process.

[0029] Specifically, the pressing structure includes a tape pressure roller 16, which is movably inserted into the bottom of the adhesive backing plate 1. A tape pressure plate fixing seat 17 is installed on the adhesive backing plate 1 and on one side of the tape pressure roller 16. An adhesive roller 18 is movably installed on the tape pressure plate fixing seat 17.

[0030] It should be noted that the non-adhesive side of the tape contacts the tape pressure roller 16, while the adhesive side of the tape pressure roller 16 adheres to the surface of the aerospace part. The adhesive roller 18 follows closely behind, rolling the newly applied tape to expel the air between the tape and the surface of the aerospace part, ensuring that the tape is tightly, firmly, and without air bubbles.

[0031] Specifically, the shearing structure includes an electric cylinder 11, which is fixedly installed on the adhesive backing plate 1. A cutter body 12 is installed at the telescopic end of the electric cylinder 11. A blade 13 is installed at one end of the cutter body 12. A pressure bar 14 is installed on the side wall of the cutter body 12. A shearing pressure roller 15 is movably installed at one end of the pressure bar 14.

[0032] It should be noted that the electric cylinder 11 adopts an augmented intelligent RPLA folding platform push rod. When the tape is pasted to the finished position, the robot moves to a specific position and stretches the tape to a certain length. The electric cylinder 11 extends from the initial position to the specific position, carrying the blade 13 to cut the tape. After the cutting is completed, the electric cylinder 11 moves to the initial position. Then, the robot works with the shearing roller 15 to perform a rolling operation to ensure that the cut tape is firmly pasted on the workpiece.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
