[0035] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] In order to solve the problem of high personnel dependence and low automation degree in the paving process in the prior art, which in turn leads to low overall paving efficiency, the present application provides a paving device.

[0037] Please refer to Figures 1 to 5 The technical scheme of the present application provides a paving device, which comprises a track vehicle assembly 10 and a paving tool 1. The track vehicle assembly 10 is movably arranged along a first direction, a second direction and a third direction, and the first direction, the second direction and the third direction are arranged perpendicular to each other. The paving tool 1 is movably connected with the track vehicle assembly 10 and located above the product to be paved. The paving tool 1 comprises a tool support 2 and a glue spraying assembly 20, a unwinding mechanism 30, a cutter assembly 40 and a pressing assembly 50 arranged on the tool support 2. The glue spraying assembly 20 is used to spray glue on the product to be paved. The unwinding mechanism 30 comprises a cloth roll 31 and a pressure roller assembly 32. At least part of the pressure roller assembly 32 is rotatably arranged and movably arranged relative to the product to be paved to approach or move away from the product to be paved. The cloth of the cloth roll 31 is laid on the surface of the product to be paved through at least part of the pressure roller assembly 32. At least part of the cutter assembly 40 is movably arranged to cut off the cloth. At least part of the pressing assembly 50 is movably arranged to contact with the product to be paved to press the cloth laid on the product to be paved.

[0038] The technical scheme of the present application is characterized in that the track vehicle assembly 10 is arranged along three mutually perpendicular directions to realize the movement of the cloth laying tool 1 along the X, Y and Z linear axes, and the cloth laying tool 1 is movably connected with the track vehicle assembly 10, so that the cloth laying tool 1 can move in all directions and cover all surfaces of the product to be laid, including the curved surface and the special-shaped surface that are difficult to reach, greatly improving the application range and flexibility of the automatic cloth laying. The glue spraying assembly 20 is used for automatic spraying, the glue amount is accurately controlled, and the bonding quality between the cloth and the surface of the product to be laid is ensured; the cloth on the cloth roll 31 is automatically laid flat and positioned by the pressing roller assembly 32; the addition of the cutter assembly 40 and the cloth pressing assembly 50 realizes the automatic cutting and compaction of the cloth after the laying is completed, reduces the manual operation steps, improves the laying efficiency and consistency, and solves the problems of high personnel dependence, low automation degree and low overall laying efficiency in the prior art. In addition, through the movable connection between the cloth laying tool 1 and the track vehicle assembly 10, the device can easily adapt to products to be laid of different sizes and shapes, facilitating the quick adjustment and optimization of the production line and enhancing the flexibility and adaptability of the production line.

[0039] In the present embodiment, the product to be laid can be a wind turbine product or other product.

[0040] In the present application, as shown in Figures 2 to 5 The unwinding mechanism 30 further comprises an unwinding assembly 33 and a material guiding assembly 34. At least a part of the unwinding assembly 33 is rotatably arranged, and the cloth roll 31 is arranged on at least a part of the unwinding assembly 33, so that the unwinding assembly 33 drives the cloth roll 31 to rotate. The material guiding assembly 34 is arranged between the unwinding assembly 33 and the pressing roller assembly 32. The free end of the cloth of the cloth roll 31 is wound around the material guiding assembly 34 and then wound around at least a part of the pressing roller assembly 32, so that at least a part of the pressing roller assembly 32 lays the cloth on the surface of the product to be laid during the movement of the cloth laying tool 1.

[0041] In the above embodiment, at least part of the unwinding assembly 33 is rotatably arranged, so that the unwinding speed can be flexibly adjusted according to the laying requirements of the cloth, thereby accurately controlling the tension of the cloth, avoiding slack or excessive stretching during unwinding, and ensuring that the cloth is laid on the product to be laid in the best state. The arrangement of the guide assembly 34 ensures that the path of the cloth from the unwinding assembly 33 to the compression roller assembly 32 is smooth, avoiding unnecessary bending and damage of the cloth during unwinding, and helping to maintain the integrity and surface quality of the cloth. In turn, through the cooperation of the guide assembly 34 and the compression roller assembly 32, the free end of the cloth can be accurately guided onto the compression roller assembly 32, so that the cloth can be accurately aligned with the laying position on the surface of the product to be laid, improving the precision and consistency of cloth laying. It can be seen that, through the automatic design of the unwinding assembly 33 and the guide assembly 34, the supply and guidance of the cloth can be continuously carried out without manual intervention, which helps to realize automatic continuous operation and greatly improves the efficiency of cloth laying.

[0042] Specifically, the unwinding assembly 33 includes two support frames 330 and a driving structure 332; the two support frames 330 are arranged relatively close to or away from each other on the tool support 2, and the two support frames 330 are respectively provided with connecting components 331, and at least part of the two connecting components 331 are respectively arranged in the mouths of the two ends of the cloth roll 31, so as to fix the cloth roll 31 through the two connecting components 331; the driving structure 332 is arranged on one support frame 330 and is drivingly connected with the connecting component 331, so that the driving structure 332 drives the cloth roll 31 to rotate through the two connecting components 331.

[0043] In this way, the two support frames 330 are arranged relatively close to or away from each other on the tool support 2, so that the unwinding assembly 33 can adapt to cloth rolls 31 of different widths, and by adjusting the distance between the support frames 330, it can be ensured that the cloth roll 31 can be stably supported at any position, preventing the cloth roll 31 from shifting or vibrating during rotation, which affects the cloth laying quality. By drivingly connecting the driving structure 332 with the connecting component 331, the rotation speed of the cloth roll 31 can be accurately controlled, so that the unwinding rate of the cloth roll 31 can be flexibly adjusted according to the required speed and tension of the cloth laying, avoiding excessive stretching or slack of the cloth, and ensuring that the cloth is laid on the product to be laid in the most suitable state. The cloth roll 31 can be unwound automatically during the unwinding process without manual operation, which not only improves the work efficiency, but also reduces the errors caused by human factors, and improves the precision and quality of the cloth laying process.

[0044] Specifically, the connecting component 331 comprises a connecting rod 3310 and a limiting piece 3311; the connecting rod 3310 is rotatably arranged on the support frame 330, and the driving end of the driving structure 332 is used to connect with the connecting rod 3310; the limiting piece 3311 is sleeved on the connecting rod 3310, and the limiting piece 3311 has a limiting conical surface with a diameter gradually decreasing away from the support frame 330, so that when the connecting rod 3310 drives the limiting piece 3311 to extend into the barrel opening of the cloth roll 31, the limiting conical surface is connected with the barrel opening to fix the cloth roll 31 relative to the connecting component 331.

[0045] The above arrangement can make the limiting conical surface of the limiting piece 3311 closely fit the inner wall of the barrel opening during the extension into the barrel opening of the cloth roll 31, and the contact area between the limiting conical surface and the barrel opening gradually increases with the deepening, forming a wedge locking effect, so as to ensure that the cloth roll 31 is stably fixed on the connecting component 331, and the cloth roll 31 can be kept from loosening or falling off even under high-speed unwinding and high load. Moreover, the conical design of the limiting piece 3311 makes the cloth roll 31 replacement process extremely simple. The operator only needs to align the barrel opening of the cloth roll 31 with the limiting piece 3311, and the limiting piece 3311 can be easily extended into the barrel opening under the driving of the connecting rod 3310 to achieve quick locking. Similarly, when replacing the cloth roll 31, the limiting piece 3311 can be quickly extracted from the barrel opening, greatly shortening the cloth roll 31 replacement time and improving the flexibility and efficiency of the production line. At the same time, the design of the limiting piece 3311 can adapt to cloth rolls 31 of different diameters, and different specifications of cloth rolls 31 can be fixed by adjusting the limiting piece 3311 to the appropriate position without replacing the connecting component 331 or making complex adjustments, thereby enhancing the versatility and adaptability of the device.

[0046] In some embodiments, the driving structure 332 comprises a first driving component 3320, a first gear 3321 and a second gear 3322; the first driving component 3320 is arranged on the support frame 330; the first gear 3321 is arranged on the support frame 330 and connected with the driving end of the first driving component 3320, and the second gear 3322 is arranged on the connecting rod 3310 and meshed with the first gear 3321; wherein the first driving component 3320 is a motor. A shock absorber is arranged on the connecting rod 3310 to absorb and weaken the vibration and impact generated by the connecting rod 3310 during rotation. For example, in the automatic cloth laying device, the robot will generate vibration when moving at high speed, stopping or turning, or the cloth pressing assembly 50 will generate vibration when contacting the cloth, and the shock absorber can effectively alleviate these vibrations to maintain the stability and accuracy of the system.

[0047] In the present application, the unwinding assembly 33 further comprises an adjusting structure 333, which is arranged on a support frame 330 and connected with the tool support 2; the adjusting structure 333 comprises a first sliding rail 3330, a first sliding piece 3331 and a second driving component 3332, the first sliding rail 3330 is arranged on the tool support 2, the first sliding piece 3331 is arranged on the support frame 330 and in sliding connection with the first sliding rail 3330, and the driving end of the second driving component 3332 is connected with the first sliding piece 3331, so as to relatively move the two support frames 330 along the extension direction of the first sliding rail 3330 to approach or move away from each other. The second driving component 3332 is a pneumatic cylinder.

[0048] In the above embodiment, the second driving component 3332 controls the movement of the first sliding piece 3331 on the first sliding rail 3330, so that one support frame 330 can slide on the first sliding rail 3330, and the distance between the two support frames 330 can be adjusted to adapt to cloth rolls 31 of different widths, thereby improving the flexibility of the unwinding assembly 33, so that the same device can be used for cloth rolls 31 of various sizes, and the versatility and production efficiency of the equipment are improved. Moreover, the design of the width adjusting structure makes it possible to automatically change the operation to adapt to the width of the cloth roll 31, without the need for manual adjustment, which not only improves the speed and efficiency of adjustment, but also reduces the labor intensity of the operator and reduces the fixing error of the cloth roll 31 caused by improper manual operation.

[0049] Specifically, the material guiding assembly 34 comprises a guiding component 340 and a suction cup component 341, the guiding component 340 comprises two guiding rods 3401 arranged in parallel with each other, the free end of the cloth of the cloth roll 31 is wound around the two guiding rods 3401 in turn and then around at least part of the compression roller assembly 32; the suction cup component 341 is arranged between the guiding component 340 and the compression roller assembly 32, and a plurality of suction nozzles 3410 are arranged on the suction cup component 341 along the extension direction thereof and spaced apart, respectively, and the plurality of suction nozzles 3410 are respectively used to contact the cloth to adsorb the cloth.

[0050] The above arrangement, the guide component 340 passes through two guide rods 3401 parallel to each other, can ensure the free end of the cloth roll 31 to be smoothly guided in the transition from the unwinding assembly 33 to the compression roller assembly 32. The arrangement of the guide rods 3401 helps to control the path of the cloth, reduces the creases and twists in the transmission process, and ensures that the cloth enters the subsequent laying process in a flat state. The plurality of suction nozzles 3410 on the suction cup component 341 can be in contact with the cloth, accurately control the position of the cloth through the adsorption force, avoid the deviation of the cloth in the guiding and laying process, help to straighten the cloth, reduce the wrinkles caused by the relaxation of the cloth, and ensure the accurate alignment of the cloth on the compression roller assembly 32, further improve the precision of the cloth laying. It can be seen that the design of the guide assembly 34 can better control the tension and position of the cloth, so that the cloth can be smoothly laid on the surface of the product to be laid by the compression roller assembly 32, improving the quality of the product to be laid.

[0051] Specifically, the compression roller assembly 32 includes two first movable structures 320 and a compression roller component 321, the two first movable structures 320 are oppositely arranged on the tool support 2; the first movable structure 320 includes a third driving component 3201, a movable rod 3202, a movable plate 3203 and an elastic member 3204, the third driving component 3201 is arranged on the tool support 2, one end of the movable rod 3202 is connected with a driving end of the third driving component 3201, the movable plate 3203 is connected with the other end of the movable rod 3202, one end of the elastic member 3204 is connected with the third driving component 3201, and the other end of the elastic member 3204 is connected with the movable plate 3203; the two ends of the compression roller component 321 are rotatably connected with the two movable plates 3203 respectively, so that the compression roller component 321 moves in the direction of approaching or moving away from the product to be laid, and the cloth of the cloth roll 31 is laid on the surface of the product to be laid in sequence through the compression roller component 321. Among them, the third driving component 3201 is a pneumatic cylinder.

[0052] In this way, by arranging the elastic member 3204, the pressure roller component 321 can automatically adjust the pressure on the cloth during cloth laying. When the pressure roller component 321 contacts the cloth or product surface, the elastic member 3204 will automatically adjust the position of the pressure roller component 321 according to the resistance, ensuring that appropriate pressure is applied under different cloth laying conditions, neither too large to cause material damage nor too small to affect the bonding effect. The pressure roller component 321 is rotatably connected to the movable plate 3203 at both ends, so that under the cooperative action of the two first movable structures 320, it can move precisely in the direction of approaching or moving away from the product to be laid, uniformly compacting the cloth, eliminating air bubbles, and improving the flatness and bonding strength of the laid cloth, thereby obtaining a high-quality product to be laid. Through the linkage of the third driving component 3201 and the movable rod 3202, automatic control of the movement of the pressure roller component 321 is realized, so that the pressure roller assembly 32 can automatically adjust the position according to the needs of the cloth laying process, without the need for manual adjustment, improving the work efficiency and automation level.

[0053] Specifically, the cloth pressing assembly 50 comprises two second movable structures 51 and a mounting shaft 52, the two second movable structures 51 being oppositely arranged on the tool support 2; the second movable structure 51 comprises a fourth driving component 510, a telescopic rod 511, a connecting piece 512, and a mounting plate 513, the fourth driving component 510 being arranged on the tool support 2, the telescopic rod 511 being connected with the driving end of the fourth driving component 510, the mounting plate 513 being arranged on the tool support 2, one end of the connecting piece 512 being rotatably connected with the telescopic rod 511, and the other end of the connecting piece 512 being rotatably connected with the mounting plate 513; the two ends of the mounting shaft 52 pass through the two mounting plates 513 correspondingly and are connected with the connecting piece 512, and a plurality of cloth pressing plates 53 are arranged on the mounting shaft 52 along the extension direction thereof, so as to drive the mounting shaft 52 to rotate through the connecting piece 512, so that the plurality of cloth pressing plates 53 are flipped around the axis of the mounting shaft 52 to contact the cloth laid on the product to be laid, so as to press the cloth. The fourth driving component 510 is a pneumatic cylinder.

[0054] In this way, the combination of the fourth driving component 510 and the telescopic rod 511 converts the linear motion of the telescopic rod 511 into the rotary motion of the connecting piece 512, so that the connecting piece 512 drives the mounting shaft 52 to rotate, and then the mounting shaft 52 can realize precise regulation and control of the pressure of the pressing plate 53. The length change of the telescopic rod 511 can automatically adjust the pressing force of the pressing plate 53 on the cloth according to the thickness of the cloth, the curved shape of the product, and different resistance encountered during cloth laying, so as to achieve the best cloth laying effect. The multiple pressing plates 53 arranged on the mounting shaft 52 can realize multi-point synchronous pressing during pressing, ensure the uniform adhesion of the cloth on the surface of the product, reduce the generation of bubbles and wrinkles, and improve the cloth laying quality and the appearance consistency of the finished product. At the same time, the automatic overturning mechanism of the pressing plate 53 reduces the need for manual operation, speeds up the cloth laying process, and improves the production efficiency.

[0057] In the present application, the track car assembly 10 includes a second sliding rail, a second sliding piece 12 and a mechanical arm 13, the second sliding rail is arranged in the vertical direction, and the second sliding piece 12 is in sliding connection with the second sliding rail; one end of the mechanical arm 13 is rotatably connected with the tool support 2, and the other end of the mechanical arm 13 is rotatably connected with the second sliding piece 12, so that the cloth laying tool 1 is movably arranged in the vertical direction relative to the track car assembly 10.

[0058] In the above embodiments, the second sliding rail extends in the vertical direction, so that the second sliding member 12 and the mechanical arm 13 thereon can move freely up and down in the vertical direction, and in turn the cloth laying tool 1 can move in the X, Y, Z three linear axes plus an additional vertical axis direction, to better adapt to the size of the wind turbine product. This design enables the cloth laying tool 1 to easily reach different heights of the product to be laid, especially when dealing with curved or irregular surface products with certain height differences, it can automatically adjust to the ideal laying height, thereby improving the adaptability and flexibility of the equipment. Moreover, the rotatable connection at both ends of the mechanical arm 13 not only enables vertical movement along the second sliding rail, but also enables lateral rotation and swinging, so that automatic adjustment and laying of the cloth can be realized during cloth laying. Combined with the vertical movement of the second sliding rail, the mechanical arm 13 can complete complex spatial path laying without manual intervention, greatly improving the automation level of cloth laying operation.

[0059] As can be seen, the above design enables the cloth laying tool 1 to be precisely positioned and controlled in three-dimensional space. Whether it is adjusted to a specific height or completes a specific angle of rotation and laying, it can be automatically operated through the control system, ensuring accurate laying of the cloth on the product surface, reducing human error and improving product quality.

The movement in each direction is controlled by precise mechanical driving, ensuring that the cloth laying tool 1 can be accurately positioned to any specified position on the product surface, which can significantly improve the accuracy and consistency of the cloth laying process.

[0062] Specifically, two lifting assemblies 70 are oppositely arranged on the mounting frame body 61, and each lifting assembly 70 includes a first mounting rod 71, a second mounting rod 72, and a mounting seat 73. The first mounting rod 71 and the second mounting rod 72 are respectively arranged in extension along the second direction, and the first mounting rod 71 is rotatably arranged. The first mounting rod 71 and the second mounting rod 72 are respectively arranged through the mounting seat 73, and the first mounting rod 71 is threadedly connected with the mounting seat 73. The two ends of the track frame 62 are respectively connected with the two mounting seats 73, so that the track frame 62 drives the track vehicle assembly 10 to move along the second direction.

[0063] In this way, the thread connection between the first mounting rod 71 and the mounting seat 73 allows the height of the mounting seat 73 to be accurately adjusted by rotating the first mounting rod 71. The fine adjustment of the paving tool 1 in the vertical height can be realized to adapt to the complex shape of the product surface. The two lifting assemblies 70 provide a stable support and an accurate movement platform for the track frame 62. Through the relative arrangement of the first mounting rod 71 and the second mounting rod 72, combined with the structure of the track frame 62, a stable movement system is formed, which can withstand the weight of the track vehicle assembly 10, the mechanical arm 13 and the paving tool 1 under load, and ensure the stability and reliability of the movement of the entire paving device in the second direction. Moreover, through automatic control, the rotation of the first mounting rod 71 can be automatically adjusted according to the product characteristics and paving requirements, so as to realize the automatic positioning of the track frame 62 in the second direction, and improve the automation level and efficiency of the paving operation.

[0064] Specifically, the paving device further includes two track assemblies 80, which are oppositely arranged on the support base surface. The track assembly 80 includes a ground track seat 81 and a ground track vehicle 82. The ground track seat 81 is arranged in extension along the first direction on the support base surface, and the ground track vehicle 82 is arranged at the bottom of the gantry frame 60 and is in sliding connection with the ground track seat 81, so that the gantry frame 60 is movably arranged along the first direction.

[0065] The above arrangement, in which the ground track seat 81 extends along the first direction, combined with the sliding connection of the ground track vehicle 82 with the bottom of the gantry frame 60, enables the gantry frame 60 and the entire paving device to move smoothly and stably horizontally on the support base surface. This design is particularly suitable for scenarios that require paving operations in a larger horizontal range, improving the layout flexibility and operation range of the device. The product to be paved can be arranged on the ground track seat 81 and below the gantry frame 60. Through the automatic and precise control of the movement of the ground track vehicle 82, manual pushing or guiding is not required, which can ensure that the paving tool 1 can accurately reach each place where the cloth needs to be laid when moving between different positions, greatly improving the automation level and accuracy of the paving operation.

[0066] In the embodiment, before the cloth laying work is performed by the cloth laying device, the layer path can be generated based on the three-dimensional CAD model of the product. The CAD model of the wind turbine generator product is read by CAM (Computer Aided Manufacturing) software, and the optimal layer path is generated according to the material characteristics and layer requirements. The direction of the layer, the continuity of the path, and the avoidance of wrinkles or bubbles of the material are considered. At the same time, the path planning combines the motion range and speed limit of the robot to ensure the efficiency and quality of the layering process.

[0067] Optionally, the layer angle and the required force are optimized in combination with finite element load analysis. For example, the T30 electric module assembly measures the force, and the finite element analysis can help determine the stress distribution of the product under different loads, thereby optimizing the direction and force of the layer to improve the reliability of the layer. By combining structural mechanics and material mechanics modeling, the layer path is optimized, and the optimized layer parameters are fed back to the layer path generation to ensure that the actual layering is consistent with the design requirements.
