[0017] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0018] Embodiments of this application provide a cover adhesive applicator 10, such as... Figure 1 and Figure 2 As shown, the outer edge of the cover 20 is used to bond with the inner wall of the air intake chamber 30. The cover adhesive applicator 10 includes an adhesive applicator 100 and a drive assembly 200. The adhesive applicator 100 includes a bracket 150, an adhesive applicator 110, and an adhesive pressing member 120. The adhesive applicator 110 and the adhesive pressing member 120 are spaced apart on the bracket 150. The adhesive pressing member 120 is used to press the adhesive released by the adhesive applicator 110. The drive assembly 200 is connected to the adhesive applicator 100. When the drive assembly 200 drives the bracket 150 to rotate along the outer edge of the cover 20, it also controls the adhesive applicator 110 to release the adhesive.

[0019] In this embodiment, the cover 20 can be an IGV cover for an auxiliary power unit. The cover 20 is installed inside the air intake chamber 30. An annular gap is formed between the outer edge of the cover 20 and the inner wall of the air intake chamber 30. The colloid fills the annular gap to achieve adhesive bonding between the cover 20 and the air intake chamber 30.

[0020] After the cover 20 is placed inside the air intake chamber 30, the adhesive application assembly 100 is adjusted to the adhesive application position. The bottoms of the adhesive application component 110 and the adhesive pressing component 120 are opposite to the annular gap on the outer edge of the cover 20. The adhesive application component 110 and the adhesive pressing component 120 are spaced apart at the bottom of the bracket 150, with a spacing of 4cm to 6cm, so that the adhesive application component 110 is in front of the adhesive pressing component 120 along the adhesive application direction. The drive assembly 200 drives the bracket 150 to rotate around the central axis of the cover 20, so that the adhesive application component 110 and the adhesive pressing component 120 rotate sequentially along the annular gap. The drive component 220 simultaneously controls the adhesive application component 110 to release the adhesive, so that the adhesive application component 110 fills the annular gap with adhesive while rotating, thereby achieving the adhesive application and installation of the cover 20. Furthermore, the annular gap forms a glue application path. The glue applicator 110 and the glue pressing component 120 are spaced along this path, allowing the glue applicator 110 to release the glue in front, while the following glue pressing component 120 presses and shapes the glue, preventing flow and accumulation. This results in a more compact and uniform glue application, ensuring the uniformity and adhesion stability of the glue layer. The drive assembly 200, via the bracket 150, can simultaneously drive the glue applicator 110 and the glue pressing component 120 to rotate, eliminating the need for a separate glue pressing drive structure, simplifying the overall device layout, reducing component redundancy, and lowering manufacturing and maintenance costs.

[0021] The drive component 200 drives the glue application component 100 to operate, enabling the glue application component 100 to automatically apply glue to the cover 20. This improves the convenience and automation of glue application to the cover 20, reduces the difficulty of glue application, minimizes manual glue application, and increases glue application efficiency. The cover glue application device 10 is integrated into a single structure, reducing the risk of tools falling into the air intake chamber 30 and preventing tools such as hooks, scrapers, and shaping balls used for manual glue application from falling into the air intake chamber 30 and causing disassembly of the air intake chamber 30. Furthermore, the pressure component 120 shapes the glue, improving the uniformity of glue application, standardizing the glue output and application effect, ensuring the airtightness and air entrainment performance of the air intake chamber 30, and preventing excessive glue application that could cause glue overflow.

[0022] In some embodiments provided in this application, such as Figure 3 As shown, the adhesive application assembly 100 includes an adhesive tube 130 and a piston block 140. The adhesive tube 130 is disposed on the bracket 150 and has an adhesive cavity 131. The adhesive cavity 131 is connected to the adhesive outlet 1121 of the adhesive applicator 110. The piston block 140 is located inside the adhesive cavity 131. The drive assembly 200 is used to drive the piston block 140 to slide along the wall of the adhesive cavity 131 to push the adhesive into the adhesive applicator 110.

[0023] In this embodiment, a specific method is provided for the drive assembly 200 to control the dispensing component 110 to release the adhesive. The dispensing tube 130 is located above the dispensing component 110. The dispensing tube 130 has a dispensing cavity 131 that provides storage space for the adhesive. The bottom wall of the dispensing cavity 131 has a discharge port with a diameter of 0.5 cm, which communicates with the dispensing port 1121 of the dispensing component 110. A piston block 140 is provided inside the dispensing tube 130. The piston block 140 is connected to the drive assembly 200. For example, the drive assembly 200 includes an electro-hydraulic push rod 260. When the electro-hydraulic push rod 260 receives a drive command, it pushes the piston block 140 forward, causing the piston block 140 to slide along the wall of the dispensing cavity 131 to push the adhesive. After entering the dispensing component 110, the adhesive is discharged through the dispensing port 1121. The piston block 140 achieves quantitative output of the adhesive through linear motion, enabling the drive component 200 to accurately control the amount of adhesive dispensed by the applicator 110, avoiding overflow or insufficient dispensing that could affect the bonding strength, and allowing the adhesive application component 100 to adapt to the adhesive application requirements of different specifications of the cover 20.

[0024] For example, the dispensing tube 130 is a cylinder with a diameter of 3 cm. The dispensing tube 130 is detachably connected to the bracket 150, allowing the operator to remove the dispensing tube 130 for dispensing, thus improving the convenience of dispensing. The outer wall of the piston block 140 is provided with a rubber ring to ensure the sealing of the piston block 140 when dispensing the adhesive.

[0025] In some embodiments provided in this application, such as Figure 5As shown, the adhesive applicator 110 includes: a connector 111, an adhesive dispensing part 112, and a traction rope 113. The connector 111 is connected to the bracket 150. The adhesive dispensing part 112 is movably connected to the bottom of the connector 111. An adhesive outlet 1121 is provided on the adhesive dispensing part 112. One end of the traction rope 113 is connected to the drive assembly 200, and the other end of the traction rope 113 is connected to the adhesive dispensing part 112. The drive assembly 200 is also used to drive the traction rope 113 to pull up the adhesive dispensing part 112, so that the adhesive dispensing part 112 moves toward the bracket 150.

[0026] In this embodiment, a specific structure of the applicator 110 is provided. The two ends of the connector 111 are respectively connected to the bracket 150 and the applicator 112. The applicator outlet 1121 is located on the bottom surface of the applicator 112. The two ends of the traction rope 113 are respectively connected to the drive assembly 200 and the applicator 112. The drive assembly 200 controls the applicator 112 to move closer to the bracket 150 via the traction rope 113, causing the applicator 112 to lift upwards. After the applicator 110 rotates one revolution, the applicator application operation is completed. The traction rope 113 drives the applicator 112 to lift upwards, raising the bottom height of the applicator 112 to avoid the adhesive and prevent the applicator 110 from damaging the shaped adhesive. The drive assembly 200 continues to drive the bracket 150 to rotate at intervals, the interval being the distance between the applicator 110 and the pressing component 120, so that the pressing component 120 completes the pressing and shaping of the adhesive at the interval between the applicator 110 and the pressing component 120.

[0027] In one possible embodiment, the dispensing element 112 is an elastic element, for example, the material of the dispensing element 112 is silicone, so as to avoid scratching the inner wall of the air intake chamber 30. When the traction rope 113 pulls the dispensing element 112, the dispensing element 112 undergoes elastic deformation, causing the bottom end of the dispensing element 112 to rotate upward with the traction rope 113 to avoid the adhesive.

[0028] In another possible embodiment, the dispensing part 112 is slidably or rotatably connected to the connecting part 111, and the traction rope 113 is used to drive the dispensing part 112 to slide or rotate upward.

[0029] In some embodiments provided in this application, such as Figure 4 and Figure 8 As shown, the glue outlet 1121 of the glue applicator 110 is located on the bottom surface of the glue applicator 110, and the bottom surface forms an inclined angle with the extension direction of the glue applicator 110. A gap is formed between the outer edge of the cover 20 and the inner wall of the air intake cavity 30. When the glue applicator 110 is in the glue application position, the projection of the glue applicator 110 along the height direction covers at least part of the gap and part of the top surface of the cover 20.

[0030] In this embodiment, an inclined dispensing method is provided. The bottom surface of the applicator 110 is inclined, and the inclination angle of the bottom surface relative to the extending direction of the applicator 110 can be 45°. The inclined dispensing port 1121 increases the dispensing area. When the applicator 110 is in the glue application position, the front tip of the bottom surface of the applicator 110 extends into the gap between the baffle 20 and the air intake chamber 30, and the rear end of the bottom surface is located above the baffle 20. Figure 8 The arrow at point X points in the height direction. The adhesive application part 110 is projected along the height direction. The projection range covers part of the gap and part of the cover 20, so that the adhesive can be accurately injected into the gap between the cover 20 and the air intake chamber 30. At the same time, the adhesive forms an auxiliary adhesive layer on the top surface of the cover 20, which enhances the sealing and reliability of the bond.

[0031] In some embodiments provided in this application, such as Figure 8 As shown, the bottom surface of the adhesive applicator 110 is provided with a guide portion 114, which is located at the lower end of the bottom surface and extends out of the bottom surface of the adhesive applicator 110 along the extending direction of the adhesive applicator 110.

[0032] In this embodiment, a pressing structure for the applicator 110 is provided. The bottom surface of the applicator 110 is inclined, resulting in different heights at both ends. The two ends of the bottom surface are a high end and a low end, with the low end having a sharp corner forming a tip. A guide portion 114 is located at this tip and extends downwards along the extension direction of the applicator 110, extending beyond the bottom surface. The guide portion 114 preferentially embeds into the edge of the gap between the cover 20 and the air intake chamber 30, providing physical positioning and ensuring that the adhesive outlet 1121 is aligned with the center of the gap, stabilizing the applicator application posture. Furthermore, the guide portion 114 guides the adhesive released by the applicator 110, allowing the adhesive to enter the gap between the cover 20 and the air intake chamber 30 more precisely, preventing the adhesive from overflowing the gap.

[0033] In some embodiments provided in this application, such as Figure 4 and Figure 5 As shown, the bottom of the pressing part 120 is provided with a spherical pressing head 121, which is used to press the adhesive. The diameter of the spherical pressing head 121 is 0.3cm to 0.7cm.

[0034] In this embodiment, a pressing structure for the adhesive pressing component 120 is provided. The bottom of the adhesive pressing component 120 adopts a spherical pressing head 121. The diameter of the spherical pressing head 121 is the same as the gap distance between the cover 20 and the air inlet chamber 30, allowing the adhesive to be pressed more fully into the gap. The diameter of the spherical pressing head 121 can be 0.5 cm. The spherical structure allows the pressing pressure to be evenly distributed on the surface of the adhesive, and the contact area with the adhesive is moderate, ensuring the pressing effect while reducing adhesive adhesion.

[0035] For example, the pressure-pressing component 120 further includes a connecting rod 122, the top end of which is connected to the bracket 150, and a spherical pressure head 121 is disposed at the bottom of the connecting rod 122. The extension path of the connecting rod 122 includes a broken line or a curve, so that the bottom of the connecting rod 122 is away from the pressure-applying component 110, thereby creating a gap between the spherical pressure head 121 and the pressure-applying component 110.

[0036] In some embodiments provided in this application, such as Figure 2 As shown, the cover adhesive applicator 10 also includes: a mounting housing 300, the bottom surface of which is used to connect with the top surface of the air intake chamber 30, an adhesive applicator 100 disposed on the bottom surface of the mounting housing 300, and a drive assembly 200 disposed on the mounting housing 300.

[0037] In this embodiment, an installation method for the cover adhesive applicator 10 is provided. The mounting housing 300 provides structural support for the adhesive applicator 100 and the drive assembly 200. The mounting housing 300 is installed using the top surface of the air intake cavity 30, avoiding the need for additional installation structures on the air intake cavity 30, simplifying the installation steps of the cover adhesive applicator 10, and improving installation convenience. Furthermore, the mounting housing 300 covers the air intake cavity 30, providing stable support for the mounting housing 300, improving the stability of the cover adhesive applicator 10, and thus making the adhesive applicator operation more stable.

[0038] For example, the bottom of the mounting housing 300 is provided with a mounting plate 310, the bottom surface of the mounting plate 310 forms the bottom surface of the mounting housing 300, and the mounting plate 310 is provided with a plurality of mounting holes spaced apart along the axial direction. The mounting housing 300 is connected to the air intake chamber 30 through the mounting holes and locking screws.

[0039] In some embodiments provided in this application, such as Figure 2 As shown, the cover adhesive applicator 10 further includes a connecting assembly 400, which includes a first rod 410, a second rod 420, and a third rod 430. The first rod 410 extends along the height direction and is connected to the mounting housing 300. The third rod 430 is connected to the adhesive applicator 100. The two ends of the second rod 420 are respectively connected to the first rod 410 and the third rod 430. The first rod 410, the second rod 420, and the third rod 430 extend in different directions.

[0040] In this embodiment, a connection method is provided between the adhesive application assembly 100 and the mounting housing 300. The connecting assembly 400 includes multiple rods connected end-to-end, with different extension directions. For example, the rods are a first rod 410, a second rod 420, and a third rod 430. The top of the first rod 410 is connected to the bottom of the mounting housing 300. The extension directions of the first rod 410 and the second rod 420 are perpendicular, while the extension directions of the second rod 420 and the third rod 430 are inclined at a connecting rod angle, which can be 45°. The bottom of the third rod 430 is connected to the bracket 150. The length of the first rod 410 is 5 cm, and the lengths of the second rod 420 and the third rod 430 are 8 cm. By limiting the length and extension direction of the different rods, the spatial position and angle of the adhesive application assembly 100 can be adjusted, allowing the adhesive applicator 110 to be precisely aligned with the adhesive application area on the outer edge of the cover 20, adapting to the complex structure of the air intake chamber 30.

[0041] For example, the first rod 410, the second rod 420 and the third rod 430 are rotatably connected, and the drive assembly 200 is also used to control the rotation angle of the second rod 420 and the third rod 430, thereby flexibly adjusting the glue application position of the glue applicator 110.

[0042] In some embodiments provided in this application, the drive component 200 includes: a cable for transmitting signals, and the connection component 400 is provided with a through hole, with a portion of the cable located inside the through hole.

[0043] In this embodiment, a method for concealing the cables is provided. The cables can be control lines or power lines. The drive component 200 transmits signals through the cables. The rods are hollow rods, so that the connecting component 400 has multiple interconnected through holes. The cables are passed through the through holes to avoid tangled cables, prevent the cables from being pulled and damaged during the adhesive application process, protect the cables from adhesive contamination, and improve the neatness of the layout.

[0044] For example, the electro-hydraulic actuator 260 is located inside the third rod 430, which provides mounting space and structural protection for the electro-hydraulic actuator 260.

[0045] In some embodiments provided in this application, such as Figure 1 and Figure 6 As shown, the drive assembly 200 also includes: a drive member 220, a reducer, a drive gear 240 and a driven gear 250. The reducer is connected to the drive member 220, the drive gear 240 is connected to the output shaft of the reducer, the driven gear 250 is meshed with the drive gear 240, and the driven gear 250 is connected to the adhesive application assembly 100.

[0046] In this embodiment, the specific structure of the drive assembly 200 is provided. The drive component 220 is located on the top surface of the mounting housing 300, the reducer is located inside the mounting housing 300, and the drive gear 240 and driven gear 250 are located on the bottom surface of the mounting housing 300. The driven gear 250 is connected to the adhesive application assembly 100 via the connecting assembly 400. The drive component 220 rotates at 200 rpm, and the reducer converts the rotational speed to 8 rpm and increases the output torque. The reducer drives the adhesive application assembly 100 to rotate via the drive gear 240 and driven gear 250, enabling the adhesive application assembly 100 to perform the adhesive application operation. The drive component 220, combined with the reducer and gear transmission, can precisely adjust the output speed, ensuring a smooth and controllable rotational speed for the adhesive application assembly 100. Furthermore, the gear meshing transmission method provides high transmission efficiency and strong stability, ensuring that the adhesive application assembly 100 rotates uniformly and stably along the outer edge of the cover 20, improving the uniformity of the adhesive layer.

[0047] For example, the drive assembly 200 also includes a control module 210, a driver 230, and a power switch. The control module 210 can be a PLC (Programmable Logic Controller), the drive element 220 is a stepper motor, and the driver 230 is a stepper motor driver. The control module 210 controls the movement of the drive element 220 through the driver 230. Figure 7 As shown, after the power switch is turned on, the control module 210 simultaneously sends control commands to the driver 230 and the electro-hydraulic push rod 260. After receiving the command, the driver 230 controls the drive component 220 to run.

[0048] When the control module 210 performs the glue application operation, it controls the drive component 220 to drive the glue applicator 110 to rotate one revolution, so that the glue applicator 110 returns to the starting point. The drive component 220 stops rotating, and the control module 210 drives the traction rope 113 to pull the glue applicator 110 up. Then, it starts the drive component 220 to make the pressing component 120 continue to travel a distance (e.g., 5cm). This distance is the gap between the pressing component 120 and the glue applicator 110, thereby completing the glue application operation.

[0049] For example, the bottom of the mounting housing 300 is provided with a support column 320, and the driven gear 250 is rotatably connected to the support column 320 through a bearing. The support column 320 provides installation space and structural support for the driven gear 250 to improve the stability of the driven gear 250.
