Description

Technical Field

[0001] This utility model relates to the field of composite material processing technology, and in particular to a positioning and application device for edge sealing protective tape. Background Technology

[0002] In aircraft manufacturing, epoxy resin-based carbon fiber and glass fiber composite materials are widely used. These resin-based composite parts are made by cutting the composite material and connecting it to T-shaped parts. However, the cut edges of the composite material and the connection points with the T-shaped parts are susceptible to humid air or moisture. Moisture may penetrate into the part and cause damage, potentially affecting its mechanical properties. To prevent performance degradation, improve surface condition, and reduce adverse effects such as crack propagation and electrochemical corrosion, the cut edges of the composite material parts need to be sealed. When applying sealant, protective tape is often used to limit the size of the sealing area, control the flow range of the sealant, and avoid contaminating non-target areas.

[0003] Currently, the application of protective tape mostly relies on manual visual inspection or fixed limiting rods. There are also some edge sealing protective tape application devices, but the existing edge sealing protective tape application devices do not have a reference surface to work independently. During the application process, it is impossible to guarantee that the same distance accuracy or application stability is maintained at all times. This leads to the sealant coverage being insufficient due to the deviation of the sealant limit area, resulting in edge moisture-proof failure, or contamination of the part surface beyond the area. Repeated adjustments or rework are required, which seriously reduces the efficiency and quality consistency of edge sealing operations, and may even create hidden dangers of mechanical property degradation of the parts.

[0004] Therefore, there is an urgent need for a positioning and application device for edge-sealing protective tape, which can solve the problem of insufficient application stability of existing devices. Utility Model Content

[0033] An anti-reverse spring is connected to one end of the second anti-reverse tooth, which can provide continuous elastic pressure to the second anti-reverse tooth, so that the second anti-reverse tooth always tightly engages with the outer teeth of the first anti-reverse tooth, thus restricting the first anti-reverse tooth from rotating in the opposite direction.

[0034] The beneficial effects of this utility model are as follows:

[0035] This utility model proposes a positioning and application device for edge sealing protective tape.

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it.

[0051] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0052] In aircraft manufacturing, epoxy resin-based carbon fiber and glass fiber composite materials are widely used. These resin-based composite parts are made by cutting the composite material and connecting it to T-shaped parts. However, the cut edges of the composite material and the connection points with the T-shaped parts are susceptible to humid air or moisture. Moisture may penetrate into the part and cause damage, potentially affecting its mechanical properties. To prevent performance degradation, improve surface condition, and reduce adverse effects such as crack propagation and electrochemical corrosion, the cut edges of the composite parts need to be sealed. When applying sealant, protective tape 40 is often used to limit the size of the sealing area, control the flow range of the sealant, and avoid contaminating non-target areas.

[0053] This embodiment provides a positioning and application device for edge-sealing protective tape, used to apply protective tape 40 to the part to be applied. The part to be applied includes a first reference surface 30 (i.e., the composite material application surface) and a first wall surface 20 (i.e., the web of the T-shaped part) arranged perpendicularly to each other. Figure 1 and Figure 2 As shown, in this embodiment, the positioning and applying device 10 for edge sealing protective tape includes a housing 1, an applying unit 2, and a positioning unit 3. The bottom of the circumferential wall of the housing 1 can abut against the first reference surface 30. The side wall of the housing 1 is perpendicular to the circumferential wall of the housing 1 and parallel to the first wall surface 20. The circumferential wall and the side wall of the housing 1 form a surrounding structure with an adhesive outlet. The applying unit 2 includes a loading base wheel 21 and an applying component 22. The loading base wheel 21 is installed inside the housing 1, and the protective tape 40 is installed on the loading base wheel 21. The loading base wheel 21 is used to carry and release the protective tape 40. The applying component 22 is installed at the adhesive outlet of the housing 1. The applying component 22 is used to press against the adhesive outlet during the applying process. The protective tape 40 is able to be tightly adhered to the first reference surface 30. The positioning unit 3 includes a positioning element 31, which is installed on the first side wall of the housing 1 with adjustable distance. The positioning element 31 can abut against the first wall surface 20 to achieve positioning of the device relative to the first wall surface 20, ensuring that the posting position maintains the same distance accuracy throughout the posting process. The positioning and posting device 10 for edge sealing protective tape can flexibly adjust the distance of the positioning element 31 according to the size of different parts to be posted or the posting requirements, thereby improving the accuracy and consistency of the posting position of the protective tape 40, avoiding posting deviations caused by inaccurate positioning, enhancing the adaptability of the device to different specifications of parts to be posted, and improving the efficiency, quality and stability of edge sealing protection operations.

[0054] Preferably, such as Figure 1 and Figure 2As shown, in this embodiment, the positioning unit 3 further includes a fixing bolt 32, a threaded guide post 33, and a limiting nut 34. The fixing bolt 32 passes through the positioning member 31 and is screwed to the outer shell 1 to adjust the distance between the outer shell 1 and the first wall surface 20. The threaded guide post 33 passes through the positioning member 31 and the outer shell 1 in sequence. The limiting nut 34 is screwed to the threaded guide post 33. The threaded guide post 33 and the limiting nut 34 cooperate with the fixing bolt 32 to achieve precise adjustment and stable locking of the position of the positioning member 31. First, the connection between the outer shell 1 and the positioning member 31 and the coarse limitation of the distance between the positioning member 31 and the outer shell 1 are achieved by the threaded guide post 33 passing through the positioning member 31 and the outer shell 1 in sequence and being screwed to the limiting nut 34. Then, the connection between the outer shell 1 and the positioning member 31 and the coarse limitation of the distance between the positioning member 31 and the outer shell 1 are achieved by the threaded guide post 33 passing through the positioning member 31 and the outer shell 1 in sequence and being screwed to the limiting nut 34. By sequentially connecting the positioning component 31 to the outer shell 1 via the fixing bolt 32, the position of the positioning component 31 on the outer shell 1 is fixed and the distance between the positioning component 31 and the outer shell 1 is precisely limited. Then, the limit nut 34 is tightened to press the positioning component 31, thereby achieving stable locking of the position of the positioning component 31. This enables precise adjustment of the distance between the positioning component 31 and the outer shell 1 and stable locking of the position of the positioning component 31, thus ensuring accurate positioning of the edge sealing protective tape positioning and pasting device 10 on different specifications of the parts to be pasted, improving the accuracy and consistency of the pasting position of the protective tape 40, avoiding pasting deviations caused by inaccurate positioning, enhancing the adaptability of the device to different sizes of parts to be pasted, and ensuring positional stability during the pasting process.

[0055] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the positioning unit 3 further includes an auxiliary roller 35, which is mounted on the positioning member 31. When the device moves along the first wall surface 20 of the part to be pasted, the sliding friction between the positioning member 31 and the first wall surface 20 is converted into rolling friction. The auxiliary roller 35 can always be in contact with the first wall surface 20, maintaining the positioning distance accuracy between the device and the wall surface, ensuring the consistency of the pasting position of the protective tape 40, and also greatly reducing the moving resistance of the device, making the pasting operation smoother and less strenuous, and avoiding wall surface scratch damage or device movement jamming caused by sliding friction.

[0056] Specifically, such as Figures 1-4 As shown, in this embodiment, the application unit 2 also includes an inner roller 23. The inner roller 23 is installed inside the housing and is positioned at the midpoint of the transmission path along the protective tape 40 between the loading base roller 21 and the application assembly 22. This inner roller 23 enables the guidance and tension stability control of the protective tape 40 from release to application, preventing the protective tape 40 from shifting, wrinkling, or loosening during transmission. It ensures that the protective tape 40 is delivered to the application assembly 22 in a flat and taut state, thereby improving the adhesion tightness and positional accuracy of the application assembly 22 when pressing the protective tape 40 onto the first reference surface 30. This reduces application deviations caused by transmission problems of the protective tape 40, further ensuring the dimensional accuracy of the sealing area and enhancing the quality and stability of the sealing operation.

[0057] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the application assembly 22 includes a slide head 221 and a fixing pin 222. The slide head 221 is installed at the adhesive outlet, and the tip of the slide head 221 includes an application roller 2211. The application roller 2211 is used to compact the applied protective tape 40. The application roller 2211 is connected to the outer shell 1 through the fixing pin 222, which enables precise guidance and tight compaction of the protective tape 40 during the application process. The fixing pin 222 stably connects the application roller 2211 and the outer shell 1. The application roller 2211 tightly presses the protective tape 40 onto the first reference surface 30, reducing the gap between the tape and the reference surface and preventing subsequent sealant penetration or the entry of air and moisture. The fixing pin 222 also ensures the stability of the position of the application roller 2211 during operation, improving the accuracy, adhesion, and operational stability of the application of the protective tape 40, thereby ensuring the quality of the edge sealing treatment of composite material parts.

[0058] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the slide head 221 also includes a limiting protrusion 2212. There are two limiting protrusions 2212, which are respectively disposed on both sides of the application roller 2211. They can block and limit the protective tape 40 in the width direction during the process of the protective tape 40 being compacted by the application roller 2211, preventing the protective tape 40 from shifting laterally or misaligning during application. This ensures that the protective tape 40 is always accurately attached to the preset sealing area, avoiding loss of control over the sealing size or contamination of non-target areas due to the offset of the protective tape 40. At the same time, in conjunction with the compaction effect of the application roller 2211, the application position of the protective tape 40 in the width direction remains consistent, improving the application consistency of different batches and different operators, thereby ensuring the accuracy of the subsequent sealant application range and reducing sealing quality problems caused by the offset of the protective tape 40.

[0059] In other embodiments, the application roller 2211 can be replaced with a silicone squeegee. The silicone squeegee, with its high elasticity and smooth edges, provides precise guidance during the application of the protective tape 40. The pressure is flexibly controlled by adjusting the angle between the squeegee and the first reference surface 30, ensuring the protective tape 40 adheres tightly to the first reference surface 30 and preventing scratches on the protective tape 40 or the surface of the composite material. In other embodiments, the silicone mounting plate can be integrally formed with the limiting protrusion 2212. This integral structure eliminates the need for assembly, reduces assembly errors between components, improves the overall structural stability, and prevents limiting failure or squeegee misalignment due to loose connections during operation.

[0060] Preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the positioning unit 3 also includes a protective shell 36. The protective shell 36 is installed at one end of the threaded guide post 33 that is relatively far from the first wall surface 20 and is connected to the slide head 221 through a connector. It can wrap the metal part of the threaded guide post 33 to prevent it from being directly exposed and prevent the metal end of the threaded guide post 33 from colliding or scratching with the composite material parts during operation, thereby preventing the parts from being bumped or scratched and protecting the surface condition and structural integrity of the parts. At the same time, the connection between the protective shell 36 and the slide head 221 can further help stabilize the position of the threaded guide post 33, reduce its shaking during the operation of the device, indirectly ensure the stability of the position of the positioning part 31, and thus maintain the accuracy of the protective tape 40, ensuring that the quality of the subsequent edge sealing operation is not affected by the damage to the parts or the positioning shaking.

[0061] Preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the positioning and pasting device 10 for the edge sealing protective tape further includes a cutting unit 4. The cutting unit 4 includes a pressing member 41, a cutting blade 42, and a spring. The pressing member 41 is installed on the circumferential wall of the outer casing 1, and the side of the pressing member 41 can abut against the first reference surface 30. The cutting blade 42 is installed on the pressing member 41 and extends into the outer casing 1, extending towards the position of the protective tape 40 to cut the protective tape 40. The spring is sleeved on the connection structure between the pressing member 41 and the circumferential wall of the outer casing 1. One end of the spring is fixed to the pressing member 41, and the other end abuts against the circumferential wall of the outer casing 1. It is used to provide a restoring elastic force after the pressing member 41 presses and cuts, thereby positioning and pasting the edge sealing protective tape. When the applicator 10 is pressed down, the actuating member 41 comes into contact with the first reference surface 30. The actuating member 41 will move upward under the reaction force of the first reference surface 30, thereby driving the cutting blade 42 to move towards the protective tape 40, thus cutting the protective tape 40. After cutting, the pressure on the device is released, and the spring's return force will push the actuating member 41 downward to return to its original position. The cutting blade 42 will then leave the area of ​​the protective tape 40, thus achieving convenient and accurate cutting of the protective tape 40. The positioning and applicating device 10 for edge sealing protective tape does not require additional cutting tools to achieve the cutting function of the protective tape 40, avoiding the deviation of manual cutting. The spring return design makes the operation more efficient, further improving the overall efficiency and quality of edge sealing protection operations.

[0062] Preferably, such as Figures 1-3As shown, in this embodiment, the outer shell 1 includes a main shell 11, a secondary shell 12, and a shell bearing 13. The loading base wheel 21 is installed inside the main shell 11, and the secondary shell 12 covers the main shell 11. The loading base wheel 21 is accommodated in the area enclosed by the main shell 11 and the secondary shell 12. The shell bearing 13 is installed on the main shell 11 and the secondary shell 12 respectively. The loading base wheel 21 is connected to the main shell 11 and the secondary shell 12 through the shell bearing 13, realizing the stable installation and flexible rotation of the loading base wheel 21 inside the outer shell 1. At the same time, it forms a container for the loading base wheel 21 and the protective tape 40. The combination of the main shell 11 and the secondary shell 12 not only provides fixed support for the loading base wheel 21, but also protects the internal protective tape 40 from external dust and moisture contamination through a near-enclosed structure. The shell bearing 13 ensures that the loading base wheel 21 rotates smoothly when releasing the protective tape 40, avoiding jamming that could cause the protective tape 40 to stretch or break, thereby ensuring the stability of the protective tape 40 application process and improving the efficiency and quality of the edge sealing operation.

[0063] Preferably, such as Figures 1-4 As shown, in this embodiment, the positioning and application device 10 for the edge sealing protective tape also includes a reverse-blocking unit 5. The reverse-blocking unit 5 is installed inside the housing 1 and connected to the loading base wheel 21. It is used to prevent the loading base wheel 21 from reversing, thus avoiding the protective tape 40 from becoming loose, retracting, or misaligned due to the unexpected reversal of the loading base wheel 21 during the application of the protective tape 40. This ensures that the protective tape 40 is always released with stable tension and the correct direction, ensuring that the protective tape 40 is tightly attached to the first reference surface 30 and the application position is accurate. At the same time, it reduces material waste and rework caused by the reversal of the protective tape 40, further improving the efficiency and quality stability of the edge sealing protection operation.

[0064] Preferably, such as Figures 1-4 As shown, in this embodiment, the anti-reverse unit 5 includes a first anti-reverse tooth 51, a second anti-reverse tooth 52, and an anti-reverse spring 53. The first anti-reverse tooth 51 is installed on the inner side wall of the outer casing 1 and is rotatably connected to the outer casing 1. The second anti-reverse tooth 52 is installed on the side wall where the first anti-reverse tooth 51 is installed and overlaps with the outer periphery of the first anti-reverse tooth 51. The anti-reverse spring 53 is connected to one end of the second anti-reverse tooth 52 and can provide continuous elastic pressure to the second anti-reverse tooth 52, so that the second anti-reverse tooth 52 is always tightly overlapped on the outer periphery teeth of the first anti-reverse tooth 51, restricting the first anti-reverse tooth 51 from rotating in the opposite direction, thereby preventing the associated loading base wheel 21 from rotating in the opposite direction. The combined structure of the first anti-reverse tooth 51, the second anti-reverse tooth 52, and the anti-reverse spring 53 can ensure that the loading base wheel 21 always maintains unidirectional stable rotation when releasing the protective tape 40, avoiding the protective tape 40 from becoming loose, misaligned, or retracted due to reversal, and ensuring the tension stability and position accuracy of the protective tape 40 when it is applied.

[0065] For ease of understanding, combined with Figures 1-4 The use of the positioning and applying device 10 for edge sealing protective tape is explained below. Specifically, before applying the tape, the sub-house 12 is opened, the protective tape 40 is installed onto the loading base wheel 21, the protective tape 40 is pre-pulled along the inner roller 23 to the tip of the slide head 221, the sub-house 12 is closed, and the threaded guide post 33 and fixing bolt 32 are adjusted so that the limiting distance of the positioner meets the working requirements. During application, the positioning member 31 abuts against the first wall surface 20, the tip of the slide head 221 abuts against the application area, and the positioning and applying device 10 for edge sealing protective tape is driven to move backward and downward for application. After the protective tape 40 is applied to the end, the pressing member 41 is pressed to cut the tape and complete the application. The application unit 2 and positioning unit 3 guide the protective tape 40 to be accurately applied to the designated position, changing the unevenness of manual application. During operation, simply pull the tape downwards and backwards to quickly complete the application, significantly improving edge sealing efficiency and shortening operation time. The threaded guide post 33 allows for flexible adjustment of the distance between the positioning device and the tape outlet, meeting various distance requirements and adapting to edge sealing operations for different parts. The auxiliary roller 35 and application roller 2211 prevent scratching parts during application, ensuring surface quality. The anti-reverse unit 5 effectively prevents tape rotation, avoiding jamming and ensuring stable operation. The cutting unit 4 allows for easy and flat tape cutting after application, and the spring ensures the reset of the pressing part 41, further enhancing ease of operation.
