They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] The solid rocket combustion chamber shell has an insulation layer inside, which is located between the inner wall of the combustion chamber shell and the solid propellant. The insulation layer mainly serves to insulate heat and resist corrosion, which can reduce the rate at which high-temperature gas transfers heat to the shell and ensure the thermal safety of the shell part during engine ignition and operation.

[0033] Traditional insulation layer manufacturing processes involve manual patch application. However, this method requires operators to enter the combustion chamber and manually apply the insulation sheet. First, adhesive is applied to the inner wall of the casing, and then the insulation sheet is pasted onto the inner wall. This process is prone to misalignment of the sheet edges, and the application time is long, resulting in low efficiency. Furthermore, manually applying adhesive to the inner wall of the combustion chamber casing using a brush results in adhesive layer thickness fluctuations ranging from 0.3 mm to 1.2 mm, leading to poor process consistency. In addition, the application efficiency is low, and operators have direct contact with toxic adhesives, posing a high safety risk.

[0034] Please refer to the following: Figures 1 to 9 The engine combustion chamber patching machine 100 provided in this application embodiment will now be described. The engine combustion chamber patching machine 100 includes: a machine base 10; a first adhesive application mechanism 20 connected to the machine base 10, which is used to apply adhesive to the combustion chamber housing 210; a conveying mechanism 30 connected to the machine base 10, which is used to convey an insulation sheet 300; and a rolling mechanism 50 disposed at the end of the conveying mechanism 30, which is used to receive the insulation sheet 300 conveyed by the conveying mechanism 30 and roll the insulation sheet 300 onto the inner wall of the combustion chamber housing 210.

[0035] The machine base 10 is the basic structural frame of the equipment, used to support and fix other functional components. The machine base 10 can be a welded metal frame or an assembled bracket, with sufficient strength and stability.

[0036] The first adhesive application mechanism 20 refers to a device for applying adhesive to the combustion chamber housing 210. It ensures the bonding strength between the housing and the insulation sheet 300 by precisely controlling the adhesive application trajectory and amount. The first adhesive application mechanism 20 can be implemented using a multi-axis robotic arm in conjunction with an adhesive application head and a metering dispensing valve. In some embodiments, the first adhesive application mechanism 20 is equipped with an adhesive application arm and an adhesive application head. The adhesive application arm is connected to the machine base 10, and the adhesive application head is installed at the end of the adhesive application arm. The adhesive application head can be a precisely controlled spraying device to uniformly spray the adhesive onto the inner wall of the combustion chamber housing 210. Furthermore, the first adhesive application mechanism 20 can be configured as a telescopic mechanism, allowing it to extend and retract within the combustion chamber housing 210; or a movement drive mechanism can be provided to move the combustion chamber housing 210 to cooperate with the first adhesive application mechanism 20 for adhesive application.

[0037] Automated operation can better ensure the thickness and uniformity of each glue application. Compared with manual operation, automated glue application can reduce glue waste and reduce the problems of irregular or excessive glue use caused by manual operation.

[0038] The conveying mechanism 30 is the power unit for conveying the insulation sheet 300. It is responsible for transporting the pre-cut insulation sheet 300 to the designated position and can continuously transport the insulation sheet 300, avoiding the inefficiency caused by manual handling. The conveying mechanism 30 can be a belt conveyor or a roller conveyor. By precisely controlling the conveying speed and path, the conveying mechanism 30 can ensure that each piece of insulation material accurately reaches the predetermined position, reducing errors caused by human factors, such as misalignment and skewing, thereby improving the quality stability of the final product.

[0039] The rolling mechanism 50 is an actuating component that presses the insulation sheet 300 to the inner wall of the housing. It eliminates air bubbles and enhances the contact tightness between the insulation sheet 300 and the housing by rolling and applying pressure. The rolling mechanism 50 can be implemented using rollers or a rolling roller in conjunction with a pressure regulating device. For example, the rolling roller can roll between the insulation sheet 300 and the inner wall of the combustion chamber housing 210, and the pressure regulating device can be implemented by a cylinder or a hydraulic cylinder, which can adjust the rolling pressure as needed.

[0040] By integrating adhesive application, conveying, and rolling modules, an automated patch-fitting process is formed, solving the problems of edge misalignment and low efficiency caused by manual operation. The first adhesive application mechanism 20 precisely applies adhesive to the inner wall of the combustion chamber shell 210, the conveying mechanism 30 ensures the continuous delivery of the insulation sheet 300 to the rolling station, and the rolling mechanism 50 achieves reliable adhesion between the insulation sheet 300 and the inner wall of the shell by mechanically pressurizing it. The overall structure works synergistically to improve process consistency and production efficiency.

[0041] The working process is as follows: the first adhesive application mechanism 20 is started, and the first adhesive application mechanism 20 first applies adhesive to the inner wall of the combustion chamber housing 210. At the same time, the conveying mechanism 30 starts to transport the insulation sheet 300, and delivers the insulation sheet 300 to the rolling mechanism 50. The rolling mechanism 50 receives the insulation sheet 300 and rolls it onto the adhesive-coated inner wall of the combustion chamber housing 210, completing the patching process.

[0042] In some embodiments, the speed at which the engine combustion chamber patcher 100 applies insulation sheets 300 can reach 12 sheets / hour, while the manual limit is only 8 sheets / hour.

[0043] The first adhesive application mechanism 20 applies adhesive to the combustion chamber housing 210 and the insulation sheet 300, reducing the problem of uneven adhesive distribution during manual application. The conveying mechanism 30 ensures the stability of the insulation sheet 300 during transport, reducing deformation caused by manual handling. Combined with the rolling mechanism 50, it solves the problem of sheet misalignment during pressing, ensuring precise adhesion between the insulation sheet 300 and the inner wall of the housing. The coordinated operation of these components achieves automated and precise installation of the insulation sheet 300, with the first adhesive application mechanism 20 ensuring the uniformity of the adhesive layer on the inner wall of the combustion chamber housing 210. The cooperation between the conveying mechanism 30 and the rolling mechanism 50 enables precise positioning and pressing of the insulation sheet 300, improving the accuracy and efficiency of the application process.

[0044] Compared with the prior art, the engine combustion chamber patch applicator 100 provided in this application embodiment, by setting a first adhesive application mechanism 20 to uniformly apply adhesive to the inner wall of the combustion chamber housing 210, can ensure the thickness and uniformity of each application. By setting a conveying mechanism 30, the insulation sheet 300 can be accurately delivered to the predetermined position, reducing errors caused by human factors. The rolling mechanism 50 receives the insulation sheet 300 from the conveying mechanism 300 and rolls it tightly onto the inner wall of the combustion chamber housing 210, while eliminating any possible air bubbles and gaps, ensuring the integrity and sealing of the insulation sheet 300. The automated operation greatly improves patch application efficiency, shortens the engine assembly cycle, enables precise positioning and efficient bonding of patches, and reduces safety issues for personnel during the patch application process.

[0045] Please refer to some embodiments of this application. Figures 6 to 8 The rolling mechanism 50 includes a roller 51 and a clamping member 52. The clamping member 52 is connected to the conveying mechanism 30 and is used to receive and clamp the insulation sheet 300. The roller 51 is rotatably connected to the conveying mechanism 30 and is used to hold the insulation sheet 300 and roll the insulation sheet 300 to the inner wall of the combustion chamber housing 210.

[0046] The clamping member 52 adopts a mechanical clamping structure, and its connection position is located on the conveying mechanism 30. The clamping end is close to the end of the conveying mechanism 30. The clamping member 52 can clamp the insulation sheet 300, and its clamping surface forms surface contact with the edge of the insulation sheet 300. The roller 51 is rotatably connected to the support of the conveying mechanism 30 through a bearing. Its axis is perpendicular to the transmission direction of the conveying mechanism 30, and the surface of the roller 51 can be covered with an elastic material layer. When the surface of the roller 51 is provided with an elastic material layer, it can generate compressive deformation when in contact with the surface of the insulation sheet 300, forming a uniformly distributed contact pressure to adapt to curved surfaces and other shapes. The roller 51 can be made of rubber material to increase the friction with the insulation sheet 300.

[0047] When the conveying mechanism 30 transports the insulation sheet 300 to the end position, the two clamping surfaces of the clamping member 52 close synchronously, fixing the two side edges of the insulation sheet 300 by friction. Simultaneously, the combustion chamber housing 210 and the roller 51 undergo relative displacement along the axial direction. The roller 51 maintains rolling contact with the inner wall of the housing and rotates around its own axis, gradually pressing the insulation sheet 300 to the predetermined position. The clamping member 52 maintains the clamping state during the rolling process until the insulation sheet 300 is completely detached from the conveying mechanism 300. At this point, the housing can rotate a certain angle to allow the next insulation sheet 300 to be attached.

[0048] In some embodiments, such as Figure 8 The clamping member 52 can be a pneumatic gripper structure, including two opposing grippers; the grippers are opened and closed by a cylinder to clamp or release the insulation sheet 300. In other embodiments, the roller 51 can be a cylindrical roller made of rubber, connected to the conveying mechanism 30 via bearings. The diameter of the roller 51 can be selected according to the curvature of the combustion chamber housing 210 to ensure a good fit.

[0049] In use, the conveying mechanism 30 transports the insulation sheet 300 to the clamping member 52, which clamps one end of the insulation sheet 300. The roller 51 abuts against the insulation sheet 300. Subsequently, the roller 51 and the combustion chamber housing 210 undergo relative displacement in the axial direction. The rolling mechanism 50 moves along the inner wall of the combustion chamber housing 210. During this process, the roller 51 applies pressure to the insulation sheet 300 and rolls it, evenly adhering the insulation sheet 300 to the inner wall of the combustion chamber housing 210. This design achieves an automated adhering process for the insulation sheet 300. The rolling action of the roller 51 ensures a tight fit between the insulation sheet 300 and the inner wall of the combustion chamber housing 210, reducing the formation of air bubbles and wrinkles. Simultaneously, the use of the clamping member 52 ensures the stability of the insulation sheet 300 during the adhering process, preventing misalignment and deformation. The automated roll bonding method significantly improves the efficiency and quality consistency of patch application, overcoming the problems of misalignment of sheet edges and poor process consistency that are easily caused by manual patch application.

[0050] Please refer to some embodiments of this application. Figures 6 to 8 The rolling mechanism 50 also includes a force-controlled swing member 53 and a connecting member 54. One end of the connecting member 54 is rotatably connected to the connecting end of the conveying mechanism 30, the roller 51 is rotatably connected to the other end of the connecting member 54, and the clamping member 52 is connected to the other end of the connecting member 54. The force-controlled swing member 53 is fixed on the conveying mechanism 30, and the swing end of the force-controlled swing member 53 is rotatably connected to the connecting member 54. The force-controlled swing member 53 is used to drive the connecting member 54 to rotate along the connection point with the conveying mechanism 30.

[0051] The connector 54 is rotatably connected to the conveying mechanism 30 to form an adjustable angle structure. The roller 51 and the clamping member 52 are fixed to the end of the connector 54, forming an integral linkage structure. The connector 54 can be a connecting rod made of metal.

[0052] The force-controlled oscillating component 53 employs a linear drive device, which can be a pneumatic cylinder or a hydraulic cylinder. The oscillating end of the force-controlled oscillating component 53 is hinged to the connecting component 54, and the rotation angle of the connecting component 54 is changed through telescopic movement. The oscillating end of the force-controlled oscillating component 53 and the connecting component 54 can be connected by a pin to achieve a rotational connection. The connecting end of the connecting component 54 and the conveying mechanism 30 can also be connected by a pin to form a hinged structure. This allows the connecting component 54 to rotate around its connection point with the conveying mechanism 30, thereby adjusting the position and angle of the roller 51. The rotation angle of the connecting component 54 is linearly related to the pressure of the roller 51 on the insulation sheet 300; the pressure of the roller 51 on the insulation sheet 300 can be controlled by adjusting the telescopic movement of the force-controlled oscillating component 53.

[0053] like Figure 7 When the force-controlled oscillating component 53 extends, the connecting component 54 rotates upward around the connection point of the conveying mechanism 30, reducing the contact pressure between the roller 51 and the insulation sheet 300; when the force-controlled oscillating component 53 shortens, the connecting component 54 rotates downward, increasing the contact pressure between the roller 51 and the insulation sheet 300. By adjusting the extension and retraction of the force-controlled oscillating component 53 in real time, it can adapt to insulation sheets 300 of different thicknesses or materials, ensuring uniform and stable pressure during the rolling process.

[0054] The rotation angle range of the connector 54 can be constrained by a mechanical limiting structure to prevent the roller 51 from detaching from the insulation sheet 300 or the material from being damaged by excessive pressure due to excessive rotation. The control signal of the force-controlled swing component 53 can be set to be synchronized with the running speed of the conveying mechanism 30, so that the pressure of the roller 51 is dynamically adjusted with the conveying speed to ensure the consistency of the rolling process.

[0055] By setting up the force-controlled oscillating component 53 and the connecting component 54, precise control of the rolling pressure of the roller 51 can be achieved. The extension and retraction of the force-controlled oscillating component 53 can drive the connecting component 54 to rotate, thereby changing the distance and contact angle between the roller 51 and the inner wall of the combustion chamber housing 210. The adjustable rolling mechanism 50 can adapt to combustion chamber housings 210 of different shapes and sizes, ensuring that the insulation sheet 300 can be evenly attached to the inner wall of the housing. At the same time, by adjusting the rolling pressure, excessive pressure on the insulation sheet 300 can be avoided, preventing deformation or damage to the insulation sheet 300. In addition, it improves the flexibility and adaptability of the rolling process, which is beneficial to improving the quality and efficiency of the patch application.

[0056] Please refer to some embodiments of this application. Figure 1 , Figure 2 and Figure 5 The engine combustion chamber patch machine 100 also includes a transfer mechanism 60, which is located on one side of the machine base 10. The transfer mechanism 60 includes a clamping arm 61 and a drive assembly 62. The clamping arm 61 is used to clamp the insulation sheet 300 transmitted by the transfer mechanism 30, and the drive assembly 62 is used to drive the clamping arm 61 to move and transport the insulation sheet 300 to the clamping member 52.

[0057] The clamping arm 61 of the transfer mechanism 60 can adopt a pneumatic gripper structure, consisting of two opposing grippers. The drive assembly 62 can be configured as a cylinder and a motor, with the cylinder driving the clamping arm 61 to move up and down or left and right, and the motor driving the clamping arm 61 to rotate.

[0058] In use, the clamping arm 61 of the transfer mechanism 60 moves to the end of the conveying mechanism 30. The clamping arm 61 first clamps the insulation sheet 300 on the conveying mechanism 30, and then the drive assembly 62 drives the clamping arm 61 to move, placing the insulation sheet 300 onto the clamping member 52 of the rolling mechanism 50. The clamping member 52 closes, completing the reception and preparing for rolling. This enables automatic transfer of the insulation sheet 300, improving the efficiency and accuracy of the bonding process. When the clamping member 52 is at an angle to the insulation sheet 300, the drive assembly 62 can drive the insulation sheet 300 to rotate so that the clamping member 52 can receive the insulation sheet 300. When the insulation sheet 300 is coated with an adhesive layer, the drive assembly 62 can also drive the insulation sheet 300 to flip. After the clamping member 52 clamps the insulation sheet 300, the adhesive surface of the insulation sheet 300 faces away from the roller 51, so that the roller 51 can roll the insulation sheet 300 onto the inner wall of the housing.

[0059] The clamping arm 61 employs an active gripping method, avoiding the uncertainties caused by free fall and ensuring that the insulation sheet 300 is accurately delivered to the predetermined position of the clamping member 52 each time. The drive assembly 62 enables the transfer and automated flipping of the insulation sheet 300, avoiding misalignment and inconsistencies that may be caused by manual operation. Simultaneously, the transfer mechanism 60, in conjunction with the conveying mechanism 30 and the rolling mechanism 50, forms a continuous automated placement process, significantly improving placement efficiency. The mechanized flipping and conveying process ensures consistency in each operation, improving the stability of placement quality.

[0060] Please refer to some embodiments of this application. Figure 5The drive assembly 62 includes a vertical drive 621, a horizontal drive 622, a vertical drive 623, and a gripper drive 624. The vertical drive 621 is connected to the drive end of the vertical drive 623, the vertical drive 623 is connected to the drive end of the horizontal drive 622, and the gripper drive 624 is connected to the drive end of the vertical drive 621. The gripping arm 61 includes two grippers 611, which are connected to the drive end of the gripper drive 624. The gripper drive 624 is used to drive the two grippers 611 to rotate and to drive the two grippers 611 to move closer to or further away from each other.

[0061] The horizontal drive unit 622 controls the clamping arm 61 to move along the first direction of the horizontal plane, the vertical drive unit 623 controls the clamping arm 61 to move along the second direction of the horizontal plane, the vertical drive unit 621 adjusts the height position of the clamping arm 61, the gripper drive unit 624 adjusts the clamping angle by rotating the gripper 611, and realizes the gripping and release of the insulation sheet 300 by opening and closing the gripper 611.

[0062] The vertical drive unit 621 can be a lead screw mechanism driven by a cylinder or a motor. The horizontal drive unit 622 and the vertical drive unit 623 can be a gear and rack mechanism driven by a slide rail and a motor. The gripper drive unit 624 can be a cylinder or a servo motor.

[0063] The gripper drive 624 and the vertical drive 621 are mechanically linked to ensure that the gripper 611 remains stable during movement. The gripper drive 624 can be configured as a pneumatic or electric actuator, and the rotation angle range of the gripper 611 can be set from 0 degrees to 180 degrees, and the opening and closing stroke can be controlled to adapt to the needs of different installation positions.

[0064] like Figure 2 When the conveying mechanism 30 conveys the insulation sheet 300 to the end, the lateral drive 622, vertical drive 623, and vertical drive 621 work together to move the clamping arm 61 below the insulation sheet 300. The vertical drive 621 adjusts the height of the clamping arm 61 to avoid interference with the conveying mechanism 30, and the jaw drive 624 drives the two jaws 611 to move closer together to clamp the insulation sheet 300. Subsequently, the lateral drive 622, vertical drive 623, and vertical drive 621 work together to transport the insulation sheet 300 above the clamping member 52. After the jaw drive 624 drives the jaws 611 to rotate to the target angle, the two jaws 611 move away from each other, releasing the insulation sheet 300 to the clamping member 52. Through the independent control of the multi-directional drive components, the clamping arm 61 can precisely adjust the position and orientation of the jaws 611, preventing the insulation sheet 300 from shifting during the transfer process and ensuring the consistency of the patch position.

[0065] With the cooperation of the aforementioned drive assembly 62, the clamping arm 61 can achieve flexible movement and precise positioning in three-dimensional space. The gripper 611 can adjust its opening and closing angle according to the size of the insulation sheet 300 to ensure stable clamping. This achieves automated clamping and precise delivery of the insulation sheet 300. The multi-degree-of-freedom design of the drive assembly 62 allows the clamping arm 61 to move flexibly, adapting to the needs of picking up and placing the insulation sheet 300 in different positions. The adjustable gripper 611 structure ensures stable clamping of insulation sheets 300 of different sizes. The overall solution improves the efficiency and accuracy of insulation sheet 300 delivery, reduces errors from manual operation, and is beneficial to improving the quality and consistency of patching in the engine combustion chamber. In some embodiments, when patching is performed using this patching machine, the patching position error can be reduced from 5mm by manual operation to approximately 2mm.

[0066] Please refer to some embodiments of this application. Figures 2 to 4 The first adhesive application mechanism 20 includes an extension 21 and a first adhesive application head 22. One end of the extension 21 is connected to the machine base 10, and the first adhesive application head 22 is connected to the other end of the extension 21. The first adhesive application head 22 is used to apply adhesive to the inner wall of the combustion chamber housing 210.

[0067] The extension member 21 can be a fixed rod or a telescopic rigid rod. One end of the extension member 21 can be fixed to the side of the machine base 10 by bolts or clips, and the other end is equipped with the first glue applicator head 22. The extension member 21 can extend horizontally, and its length can be set to be relatively long to accommodate shells of different diameters.

[0068] The extension 21 is linearly extended and retracted by a lead screw driven by a servo motor, or the combustion chamber housing 210 can be horizontally moved so that the first glue applicator 22 can move radially to a specified position on the housing surface. The extension 21 moves relative to the housing so that the first glue applicator 22 moves to the edge of the housing end. The glue is delivered to the storage chamber of the first glue applicator 22 through a pressure pump and pipeline along the extension, and then flows out evenly from the glue outlet to form a glue line.

[0069] The first adhesive applicator 22 can be a nozzle that sprays adhesive onto the inner wall of the combustion chamber housing 210 under pressure. The first adhesive applicator 22 can also have multiple nozzles to improve application efficiency and uniformity. Alternatively, the first adhesive applicator 22 can be configured as a brush for even application. The first adhesive applicator 22 has an internal adhesive storage chamber and multiple adhesive outlet holes at the bottom for even dispensing. Furthermore, an adhesive pressure tank 90 is connected to the first adhesive applicator 20 for replenishing adhesive.

[0070] In some embodiments, the first adhesive application mechanism 20 is connected to a micro-flow pump 23, which, through closed-loop system control, can reduce the adhesive thickness fluctuation range to ±0.04mm. Precise metering system control reduces adhesive waste. In other embodiments, the second adhesive application mechanism 40 is also connected to a micro-flow pump 23, which, through closed-loop system control, can reduce the adhesive thickness fluctuation range to ±0.04mm, ensuring uniform adhesive application and reducing adhesive waste.

[0071] In addition, a drive unit can be set to control the first adhesive applicator 22 to move up and down and get close to the inner wall of the housing; or the combustion chamber housing 210 can move up and down so that the first adhesive applicator 22 can contact its inner wall to apply adhesive.

[0072] By incorporating the extension member 21 and the first adhesive applicator 22, automated adhesive application to the inner wall of the combustion chamber housing 210 is achieved, isolating operators from contact with toxic adhesives. The extension member 21 allows the first adhesive applicator 22 to adapt to combustion chamber housings 210 of varying lengths. The first adhesive applicator 22 can uniformly spray adhesive onto the inner wall of the housing, improving the consistency and efficiency of the application. This automated application method reduces errors from manual operation, improves the adhesion quality between the insulation layer and the housing, thereby enhancing the engine's thermal safety and reliability.

[0073] In addition, a video monitoring system can be installed to track and monitor the patch in real time during processing and record details of the process. Furthermore, the equipment can be connected to a remote control system using a multi-axis AC servo drive unit to achieve continuous motion trajectory control.

[0074] Please refer to some embodiments of this application. Figure 3 and Figure 6 The conveying mechanism 30 includes a vacuum adsorption belt 31, which is used to adsorb and convey the insulation sheet 300. The rolling mechanism 50 is located at the end of the vacuum adsorption belt 31.

[0075] The conveying mechanism 30 is configured as a vacuum adsorption belt component 31, which uses negative pressure adsorption force to fix the surface of the insulation sheet 300, preventing it from sliding or shifting during the conveying process, or causing problems such as accumulation. The surface of the vacuum adsorption belt component 31 is distributed with adsorption holes, and the adsorption force is generated by a vacuum pump. The insulation sheet 300 is adsorbed on the belt surface and moves with it at a uniform speed.

[0076] During this process, the insulation sheet 300 completes position calibration before detaching from the vacuum adsorption belt 31, ensuring that it enters the clamping range of the rolling mechanism 50 in a precise posture.

[0077] In some embodiments, such as Figure 3 The conveying mechanism 30 includes multiple vacuum adsorption belts 31 to complete the coating, conveying and patching process of the insulation sheet 300.

[0078] The vacuum adsorption belt assembly 31 consists of multiple vacuum adsorption units, each including a belt body and adsorption holes. The belt body is made of wear-resistant material with a smooth surface. The adsorption holes are evenly distributed on the surface of the belt body and are connected to a vacuum pump. After the vacuum pump is started, a negative pressure is generated through the adsorption holes, firmly adsorbing the insulation sheet 300 onto the belt surface. The operating speed of the vacuum adsorption belt assembly 31 is adjustable to adapt to the conveying requirements of insulation sheets 300 of different sizes. The width of the vacuum adsorption belt assembly 31 is slightly larger than the width of the insulation sheet 300 to ensure that the insulation sheet 300 is completely placed on the belt.

[0079] The rollers 51 of the rolling mechanism 50 are arranged perpendicular to the conveying direction of the vacuum adsorption belt 31, and are used to press the insulation sheet 300 against the inner wall of the combustion chamber housing 210. The clamping member 52 is used to receive and fix the insulation sheet 300, ensuring that the insulation sheet 300 enters the rolling area flat.

[0080] The vacuum adsorption belt 31 enables automatic conveying and precise positioning of the insulation sheet 300. The vacuum adsorption belt 31 firmly adsorbs the insulation sheet 300, preventing displacement or detachment during conveying. The rolling mechanism 50 cooperates with the vacuum adsorption belt 31 to ensure that the insulation sheet 300 is flat and adheres to the inner wall of the combustion chamber shell 210. The overall solution improves the automation level and process consistency of the insulation layer manufacturing, increases the patching efficiency, and reduces the risk of misalignment.

[0081] Please refer to some embodiments of this application. Figure 7 The conveying mechanism 30 also includes a limiting roller 32, which is connected to the end of the vacuum adsorption belt 31 and is arranged in a direction perpendicular to the conveying direction of the vacuum adsorption belt 31. The limiting roller 32 is used to receive the insulation sheet 300 and limit the insulation sheet 300 so that the insulation sheet 300 enters the rolling mechanism 50.

[0082] like Figure 7 When the vacuum adsorption belt 31 conveys the insulation sheet 300 to the end, the insulation sheet 300 will sag under the action of gravity, while continuing to move and contacting the limiting roller 32. The limiting roller 32, through its arrangement in the vertical conveying direction, constrains the lateral displacement of the insulation sheet 300, causing it to enter the clamping area of ​​the rolling mechanism 50 along a preset path.

[0083] The vacuum adsorption belt 31 and the limiting roller 32 form a two-stage positioning structure. The first stage maintains the position of the main body of the insulation sheet 300 through adsorption force, and the second stage adjusts the position of the insulation sheet 300 through mechanical limiting. Through the dual action of adsorption and limiting, the positional error of the insulation sheet 300 during the transmission stage is controlled within the allowable range, thereby avoiding patch defects caused by misalignment.

[0084] The rotation of the limiting roller 32 reduces frictional resistance with the insulation sheet 300, preventing damage to the material surface. By adjusting the position and gap of the limiting roller 32, it can accommodate insulation sheets 300 of different thicknesses or sizes, ensuring consistent limiting effect. Replacing manual adjustment with mechanical limiting reduces positioning errors caused by insulation sheet 300 offset during transport, improving bonding efficiency and process stability.

[0085] In some embodiments, at least two limiting rollers 32 are provided, and the two limiting rollers 32 are spaced apart in a direction perpendicular to the conveying direction. This can better constrain the position of the insulation sheet 300 and effectively solve the problem of positioning deviation of the insulation sheet 300 at the end of the conveying process due to inertia or offset.

[0086] By setting the limiting roller 32, the position of the insulation sheet 300 is precisely corrected before entering the rolling mechanism 50, ensuring that the insulation sheet 300 and the inner wall of the combustion chamber shell 210 are accurately attached during the rolling process, thereby improving the stability and consistency of the patching process.

[0087] Please refer to some embodiments of this application. Figure 3 The first glue-applying mechanism 20 and the conveying mechanism 30 are arranged in parallel at intervals.

[0088] The parallel arrangement allows the first adhesive application mechanism 20 and the conveying mechanism 30 to be distributed side by side in the horizontal direction, avoiding spatial conflicts caused by vertical stacking or cross arrangement, and making the overall structure more compact. While the conveying mechanism 30 continuously transports the insulation sheet 300, the first adhesive application mechanism 20 can independently apply adhesive to the inner wall of the clamped combustion chamber shell 210. The two do not interfere with each other, realizing simultaneous adhesive application and material preparation, significantly shortening the single application cycle time. After the adhesive application is completed, the system can trigger the conveying mechanism 30 to start, ensuring that the insulation sheet 300 is bonded within the optimal adhesion window period after the shell adhesive application is completed.

[0089] For combustion chamber housings 210 of different diameters or lengths, the first adhesive application mechanism 20 can be laterally adjusted along the guide rail, while the conveying mechanism 30 remains fixed. Simultaneously, when the first adhesive application mechanism 20 and the rolling mechanism 50 are equipped with mechanisms to drive them closer to the inner wall of the housing, the combustion chamber housing 210 can remain at the same height and position throughout the entire process, without the need for lifting or translation adjustments.

[0090] Please refer to some embodiments of this application. Figure 1 and Figure 9 The engine combustion chamber patch machine 100 also includes a second adhesive application mechanism 40, which is connected to the machine base 10 and located above the conveying mechanism 30, and is used to apply adhesive to the insulation sheet 300.

[0091] The second adhesive application mechanism 40 is a device for applying adhesive to the insulation sheet 300. It is positioned above the conveying path to ensure uniform adhesive coverage on the surface of the insulation sheet 300. The second adhesive application mechanism 40 can employ a fixed adhesive application head or a movable spraying assembly. For example, the second adhesive application mechanism 40 may include a fixed frame and an adhesive application head. The fixed frame spans above the conveying mechanism 30, and the adhesive application head is mounted on the fixed frame and can move vertically along the fixed frame to approach the insulation sheet 300. The adhesive application head uses a brush design to uniformly apply adhesive to the surface of the insulation sheet 300 during transport.

[0092] The first adhesive application mechanism 20 and the second adhesive application mechanism 40 respectively apply adhesive precisely to the housing and the insulation sheet 300. This double-coating design ensures good adhesion between the insulation sheet 300 and the inner wall of the combustion chamber housing 210, enhancing their bonding strength and providing a better foundation for subsequent rolling processes. In addition, an adhesive pressure tank (not shown in the figure) is connected to the second adhesive application mechanism 40 to replenish the adhesive.

[0093] While the first adhesive applicator 20 applies adhesive to the inner wall of the combustion chamber housing 210, the conveying mechanism 30 begins to transport the insulation sheet 300. The second adhesive applicator 40 applies adhesive to the surface of the heat insulation sheet 300 during transport. After the adhesive application is completed, the conveying mechanism 30 transports the adhesive-applied heat insulation sheet 300 to the rolling mechanism 50.

[0094] In some embodiments, such as Figure 9 The second adhesive coating mechanism 40 is located above the vacuum adsorption belt component 31. The setting of the second adhesive coating mechanism 40 enables uniform adhesive coating on the surface of the insulation sheet 300, thereby improving the adhesive coating efficiency and quality.

[0095] Please refer to some embodiments of this application. Figure 3 and Figure 9 The engine combustion chamber patch machine 100 also includes a hopper 71 and a feeding mechanism 72. The hopper 71 is used to hold the insulation sheet 300, and the feeding mechanism 72 is used to transfer the insulation sheet 300 from the hopper 71 to the conveying mechanism 30.

[0096] The hopper 71 is a container with a multi-layer stacked structure, and its interior is equipped with partitions to fix the position of the insulation sheet 300. The feeding mechanism 72 can be configured as a positioning clamping component or a suction cup component, etc. In some embodiments, such as Figure 3 The hopper 71 has a rectangular structure and contains a storage area for stacked insulation sheets 300. In other embodiments, such as... Figure 9 The feeding mechanism 72 is set as a vacuum suction cup assembly. The vacuum suction cup assembly is connected to the hopper 71 through a linear slide rail. The surface of the suction cup is covered with a flexible material to avoid damaging the insulation sheet 300.

[0097] In some embodiments, such as Figure 9The feeding mechanism 72 includes a three-axis robotic arm with a vacuum suction cup assembly at its end. The vacuum suction cup assembly is connected to a negative pressure air source via a solenoid valve. When the vacuum suction cup moves above the storage area of ​​the hopper 71, a cylinder drives the suction cup to descend and adsorb the uppermost insulation sheet 300. The robotic arm then transfers the insulation sheet 300 along a preset path to the starting end of the vacuum suction belt assembly 31. The hopper 71 can be located on or beside the machine base 10. Figure 1 The hopper 71 is located on one side of the machine base 10, and the conveying mechanism 30 is connected between the hopper 71 and the machine base 10.

[0098] After the insulation sheet 300 is manually placed into the hopper 71, the vacuum suction cup of the feeding mechanism 72 adsorbs the insulation sheet 300 under negative pressure, and then moves it along a linear slide rail to above the vacuum adsorption belt 31 of the conveying mechanism 30. When the vacuum suction cup releases the insulation sheet 300, the vacuum adsorption belt 31 uses micropores distributed on its surface to generate adsorption force to fix the insulation sheet 300, preventing it from shifting during the conveying process. This achieves automated storage and precise feeding of the insulation sheet 300, effectively avoiding material shifting or deformation caused by manual handling.

[0099] Please refer to some embodiments of this application. Figure 3 The engine combustion chamber patch machine 100 also includes an adhesive application drive 80, which is connected to the machine base 10. The first adhesive application mechanism 20 is connected to the drive end of the adhesive application drive 80, and the adhesive application drive 80 is used to drive the first adhesive application mechanism 20 to move along the height direction.

[0100] The adhesive application drive 80 adjusts the position of the first adhesive application head 22 according to the height of the combustion chamber housing 210, so that the first adhesive application head 22 contacts the inner wall of the housing for adhesive application. The adhesive application drive 80 can be a combination of a motor and a lead screw, with the end of the lead screw rigidly connected to the extension 21 of the first adhesive application mechanism 20. After receiving a control signal, the motor drives the extension 21 to move vertically. The height-adjustable adhesive application mechanism ensures uniform adhesive application, solving the edge misalignment problem caused by unstable operation in traditional manual patching processes, and significantly improving the process consistency and production efficiency of insulation layer bonding.

[0101] In some embodiments, the cut insulation sheet 300 is manually placed into the hopper 71. The combustion chamber shell 210 is mounted on the moving platform 220. The moving platform 220 moves the combustion chamber shell 210 to the first gluing mechanism 20. The gluing drive 80 drives the first gluing mechanism 20 to descend until it is close to the shell. The first gluing mechanism 20 evenly applies glue to the inner wall of the shell. After the glue is applied, the moving platform 220 automatically removes the combustion chamber shell 210 from the first gluing mechanism 20 and moves it to the rolling mechanism 50. While the first gluing mechanism 20 is applying glue, the feeding mechanism 72 transfers the insulation sheet 300 in the hopper 71 to the conveying mechanism 30. The conveying mechanism 30 automatically conveys the insulation sheet 300 to the... Below the second adhesive application mechanism 40, the second adhesive application mechanism 40 descends, approaches the insulation sheet 300, and applies adhesive evenly to the insulation sheet 300. After the adhesive is applied to the inner wall of the combustion chamber housing 210 and the insulation sheet 300, wait for five minutes. Then, the conveying mechanism 30 conveys the insulation sheet 300 forward to the end. The transfer mechanism 60 receives the insulation sheet 300, flips it, and conveys it to the rolling mechanism 50 for clamping. The rolling mechanism 50 then rolls the insulation sheet 300 onto the inner wall of the combustion chamber housing 210. The moving platform 220 moves the combustion chamber housing 210 so that the insulation sheet 300 can be firmly adhered to the housing, completing the adhesion of one insulation sheet 300. Then, the moving platform 220 rotates the combustion chamber housing 210 by a certain angle to allow the adhesion of the next insulation sheet 300.

[0102] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
