Technical Field

[0001] This invention relates to an adhesive bonding device, and more particularly to an automatic adhesive bonding device for nodes of carbon fiber honeycomb panel sheets. Background Technology

[0002] Carbon fiber honeycomb panels are made by bonding forward and reverse sheets together using adhesive bonding equipment. Existing adhesive bonding equipment relies on manual assistance in handling the sheets during the transfer process, making automated production impossible. This manual intervention leads to poor consistency in the finished products. Furthermore, the transfer process suffers from insufficient positioning accuracy, slippage of the sheets due to excessive angles affecting the stability and reliability of the transfer, potentially damaging the sheet surface. Additionally, it has poor adaptability to sheets of different specifications, requiring frequent manual adjustments, resulting in low production efficiency. Summary of the Invention

They are only for the convenience of describing this invention 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 limiting the scope of protection of this invention.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention discloses an automatic bonding device for carbon fiber honeycomb panel nodes, comprising a support frame, a carbon fiber honeycomb panel transfer mechanism, a glue application mechanism 04, a fiber cross-lamination mechanism 05, a waste gas treatment device 06, a transfer and unloading device 07, a paint bucket 08, an operation display screen 09, and a control mechanism. The carbon fiber honeycomb panel transfer mechanism includes a raw material lifting module 01 and a transfer module 02, as shown in the figure. Figure 4 , Figure 5As shown, the raw material lifting module 01 includes a first linear guide rail 11, a first raw material pallet 12, a second linear guide rail 13, and a second raw material pallet 14. The first linear guide rail 11 and the second linear guide rail 13 are both vertically arranged. The first raw material pallet 12 and the second raw material pallet 14 are respectively adapted to move up and down relative to the first linear guide rail 11 and the second linear guide rail 13. The first raw material pallet 12 is used to lift the forward-facing sheet 120, and the second raw material pallet 14 is used to lift the reverse-facing sheet 140. Specifically, the first linear guide rail 11 and the second linear guide rail 13 are both connected to a support frame. The first raw material tray 12 and the second raw material tray 14 are connected to the first linear guide rail 11 and the second linear guide rail 13 respectively via sliders. The raw material lifting module 01 also includes two driving cylinders. The piston rod ends of the two driving cylinders are connected to the first raw material tray 12 and the second raw material tray 14 respectively. The first raw material tray 12 and the second raw material tray 14 are lifted by driving the driving cylinders, thereby realizing the layer-by-layer lifting of the forward sheet 120 and the reverse sheet 140, ensuring the orderly supply of sheets, avoiding stacking chaos, and providing convenience for subsequent material handling operations. The material transfer module 02 includes a first raw material adsorption module 21 and a second raw material adsorption module 22, both located above the raw material lifting module 01. A control mechanism controls the raw material lifting module 01 and the material transfer module 02. The first and second raw material adsorption modules 21 and 22 are respectively used to adsorb the forward-facing sheet 120 on the first raw material tray 12 and the reverse-facing sheet 140 on the second raw material tray 14. The first raw material adsorption module 21 is adapted to move vertically up and down, and also moves longitudinally and laterally relative to the support frame. Under the control of the control mechanism, the first and second raw material adsorption modules 21 and 22 move longitudinally and laterally relative to the support frame until they are above the first and second raw material trays 12 and 14, respectively, and then move vertically up and down until the first raw material adsorption module 21 adsorbs the forward-facing sheet 120 onto the bottom surface, and the second raw material adsorption module 22 adsorbs the reverse-facing sheet 140 onto the bottom surface. The glue application mechanism 04 is located downstream of the material transfer module 02, such as... Figure 3 , Figure 6 As shown, the adhesive coating mechanism 04 includes an adhesive coating roller 42, which is used to apply adhesive to the forward-facing sheet 120 adsorbed by the first raw material adsorption module 21 and the reverse-facing sheet 140 adsorbed by the second raw material adsorption module 22. Under the control of the control mechanism, the first raw material adsorption module 21 with the forward-facing sheet 120 and the second raw material adsorption module 22 with the reverse-facing sheet 140 continue to move longitudinally and laterally relative to the support frame, and are adjusted to a suitable height in the vertical direction so that the forward-facing sheet 120 and the reverse-facing sheet 140 contact the adhesive coating roller 42 to complete the adhesive coating. The fiber interlacing and laminating mechanism 05 is located downstream of the gluing mechanism 04. The fiber interlacing and laminating mechanism 05 is used to pressurize and cure the forward sheet 120 and the reverse sheet 140. Under the control of the control mechanism, the fiber interlacing and laminating mechanism 05 pressurizes the glued forward sheet 120 and the reverse sheet 140 to form a carbon fiber honeycomb panel.

[0021] This invention discloses an automatic bonding equipment for carbon fiber honeycomb panel sheet nodes. It comprises a carbon fiber honeycomb panel material transfer mechanism, an adhesive application mechanism 04, a fiber cross-lamination mechanism 05, and a control mechanism. The control mechanism controls the actions of the carbon fiber honeycomb panel material transfer mechanism, adhesive application mechanism 04, and fiber cross-lamination mechanism 05. Furthermore, these mechanisms are modularly configured, enabling automated control of each module. Compared to bonding equipment requiring manual intervention, this equipment offers higher positioning accuracy, higher finished product bonding quality, and higher bonding efficiency. The first raw material tray 12 and the second raw material tray 14 can lift sheets of different specifications, and the first raw material adsorption module 21 and the second raw material adsorption module 22 can adsorb sheets of different specifications. Therefore, this automatic bonding equipment for carbon fiber honeycomb panel sheet nodes can adapt to sheets of different specifications, has a wider range of applications, reduces bonding consistency issues caused by manual intervention, and meets the production needs of high-precision carbon fiber honeycomb panel sheet node bonding in aerospace, automotive manufacturing, and other fields.

[0022] Optionally, such as Figure 7 , Figure 8 As shown, the material transfer module 02 also includes a first longitudinal moving bracket 23, a second longitudinal moving bracket 24, and a longitudinal drive component. The first longitudinal moving bracket 23 and the second longitudinal moving bracket 24 are connected to the support frame and can slide longitudinally relative to the support frame. Each of the first longitudinal moving bracket 23 and the second longitudinal moving bracket 24 is provided with a transverse slide rail, such as... Figure 7 The first longitudinal moving bracket 23 is provided with a transverse slide rail 231. The first raw material adsorption module 21 is slidably connected to the transverse slide rail 231 of the first longitudinal moving bracket 23. The second raw material adsorption module 22 is slidably connected to the transverse slide rail of the second longitudinal moving bracket 24. The longitudinal driving component includes a servo motor 31, a drive shaft 32, and a transmission belt 33. The drive shaft 32 is connected to the output shaft of the servo motor 31, and the transmission belt 33 is wound around the drive shaft 32. The first longitudinal moving bracket 23 and the second longitudinal moving bracket 24 are connected to different length positions of the transmission belt 33 through the first upright plate 232 and the second upright plate 241. When the servo motor 31 is started, it drives the transmission belt 33 to move, thereby causing the first longitudinal moving bracket 23 and the second longitudinal moving bracket 24 to move longitudinally relative to the support frame. Figure 3As shown, a set of longitudinal guide rails 25 are provided on the support frame. The first longitudinal moving bracket 23 and the second longitudinal moving bracket 24 are respectively connected to the longitudinal guide rails 25 via sliders. The longitudinal drive component drives the transmission belt to move through the servo motor 31, thereby driving the first longitudinal moving bracket 23 and the second longitudinal moving bracket 24 to move. This results in higher control precision, further improving the position control capability of the automatic gluing equipment for carbon fiber honeycomb panel nodes of the present invention, and further improving the gluing quality of the finished product.

[0023] Optionally, the transfer module 02 further includes a first fine-tuning transfer component and a second fine-tuning transfer component. The first fine-tuning transfer component and the second fine-tuning transfer component have the same structure. The first fine-tuning transfer component is located near the first longitudinal moving bracket 23, and the second fine-tuning transfer component is located near the second longitudinal moving bracket 24. The first fine-tuning transfer component includes a stepper motor 35, a brush shaft 36, and multiple brushes 37. The multiple brushes 37 are respectively located at different length positions of the brush shaft 36. The stepper motor 35 drives the brush shaft 36 to rotate, thereby driving the brushes 37 to rotate. The brushes of the first fine-tuning transfer component and the brushes of the second fine-tuning transfer component are used to drive the forward sheet 120 and the reverse sheet 140 to move longitudinally, respectively. The stepper motor 35 rotates at a fixed step angle according to the pulse signal, driving the brush shaft 36 and brush 37 to rotate. The brushes of the first and second fine-tuning material transfer components are located above the forward sheet 120 and the reverse sheet 140. Through friction, the brushes precisely adjust and push the forward sheet 120 and the reverse sheet 140 to move longitudinally, avoiding damage to the honeycomb panel sheet. The forward sheet 120 and the reverse sheet 140 are controlled with the correct posture and direction, realizing precise control of the longitudinal movement distance, speed and direction of the first longitudinal movement bracket 23 and the second longitudinal movement bracket 24, accurately controlling the position of the forward sheet 120 and the reverse sheet 140, and further improving the bonding quality of the finished product.

[0024] Optionally, such as Figure 9 , Figure 10As shown, the first raw material adsorption module 21 and the second raw material adsorption module 22 have the same structure. The first raw material adsorption module 21 includes a material taking mold 211 and a material taking mold lifting device 212. The material taking mold 211 is connected to the bottom of the material taking mold lifting device 212, and the top of the material taking mold lifting device 212 is connected to the transverse slide rail on the first longitudinal moving bracket 23. The material taking mold 211 is used to pick up or put down the positive sheet 120. Specifically, the first raw material adsorption module 21 also includes a drive cylinder. After the first longitudinal moving bracket 23 and the second longitudinal moving bracket 24 move longitudinally to a predetermined position, the piston rod of the drive cylinder is connected to the material taking mold lifting device 212. The extension and retraction of the piston rod drives the material taking mold lifting device 212 to move laterally along the transverse slide rail. The transverse slide rail ensures accurate movement direction. By controlling the extension and retraction amount and speed of the piston rod, accurate lateral positioning is achieved, and finally, the precise position adjustment of the first longitudinal moving bracket 23 and the second longitudinal moving bracket 24 in the transverse and longitudinal dimensions is completed.

[0025] The first raw material adsorption module 21 also includes a vacuum generator 213. The material handling mold 211 includes an adsorption plate with multiple adsorption holes. The vacuum pipe of the vacuum generator 213 is connected to the adsorption holes. During operation, the vacuum generator 213 is activated, generating a stable vacuum adsorption force through the adsorption holes to tightly adsorb the forward sheet 120 and the reverse sheet 140. This can adapt to carbon fiber honeycomb panel sheets of different thicknesses, thus broadening its application range.

[0026] Optionally, the material handling mold 211 also includes a buffer layer 2111, which is attached to the material handling mold 211. Because the material handling mold 211 is provided with a buffer layer 2111, during material handling, the buffer layer 2111 gently contacts the sheet surface, avoiding damage to the sheet due to the impact force at the moment of adsorption; when placing the sheet, it can also provide uniform buffering force to ensure that the sheet is placed stably and reduce scratches on the sheet surface.

[0027] Optionally, the first raw material adsorption module 21 further includes an elastic buffer device 214. The material taking mold lifting device 212 is connected to the transverse slide rail 231 on the first longitudinal moving support 23 via a slider. The elastic buffer device 214 is disposed between the material taking mold lifting device 212 and the slider, and is adapted to extend and retract in the vertical direction. The elastic buffer device 214 uses a spring. Under the action of the elastic buffer device, when the material taking mold 211 is lowered by the material taking mold lifting device 212 and contacts the sheet, it can absorb the positioning error in the vertical direction and the impact force during the descent, preventing physical damage to the fragile carbon fiber sheet and ensuring a flexible and tight fit between the material taking mold and the sheet surface.

[0028] The first raw material adsorption module 21 also includes a material pick-up mold fine-tuning device, which includes a lateral fine-tuning component and a rotating component 215. The rotating component drives the material pick-up mold lifting device 212 to rotate relative to the slider, and the lateral fine-tuning component drives the slider to move a small distance on the lateral slide rail 231. Specifically, the material pick-up mold lifting device 212 includes multiple cylinders, which synchronously control the rise and fall of the first raw material adsorption module 21 through the extension and retraction of the piston rod. When transferring the sheet, the cylinders drive the first raw material adsorption module 21 to fall to a suitable height, adsorb the sheet, and then rise again, and then move laterally and longitudinally. After the sheet is adsorbed, the material pick-up mold fine-tuning device performs a small amount of translation and rotation compensation correction on its planar position to ensure that the sheet reaches the preset precise alignment requirements before being transferred to the next station. The lateral fine-tuning component uses a servo motor as a power source. The output shaft of the servo motor is connected to a ball screw through a coupling and other transmission components. The ball screw is threaded with the slider, and the rotational motion of the servo motor is precisely converted into the linear motion of the slider through the ball screw nut pair.

[0029] Optionally, the glue application mechanism 04 also includes a glue box 41 and a glue scraper assembly. A glue application roller 42 is disposed within the glue box 41 and is driven to rotate by a roller drive component, i.e., a motor. The glue scraper assembly includes a first scraper 431, multiple scraper micro-heads 432, and multiple second scrapers. The first scraper 431 is disposed on one side of the top of the glue box 41. The multiple scraper micro-heads 432 are arranged sequentially along the length of the glue application roller 42, and each scraper micro-head 432 is connected to a second scraper. The scraper micro-heads 432 are used to finely adjust the position of the second scrapers. The scraper micro-heads 432 adjust the distance between the second scrapers and the glue application roller 42 through a micrometer-level adjustment mechanism, thereby achieving micron-level precision adjustment of the glue application thickness. When adjusting the adhesive coating thickness, the first adhesive coating thickness is coarsely adjusted using the first adhesive scraper 431, and then the adhesive coating thickness is precisely adjusted at the micron level using the second adhesive scraper to ensure that the adhesive layer coating on the sheet surface is uniform in thickness.

[0030] Specifically, the glue coating mechanism 04 also includes an excess glue scraper and an excess glue scraper adjustment and locking device 47. The excess glue scraper is located on the opposite side of the glue box 41 from the first glue scraper 431. The excess glue scraper is used to scrape off and clean the excess glue adhering to the roller surface. After the excess glue scraper is adjusted to the correct position, the excess glue scraper adjustment and locking device 47 is operated to rigidly lock the excess glue scraper, ensuring that the position and angle of the excess glue scraper remain constant under the long-term, high-intensity operation of the equipment and the presence of vibration, thus ensuring the high repeatability of the glue coating process.

[0031] The adhesive application mechanism 04 also includes a water bath 44 and an upper cover 45. The water bath 44 is located below the adhesive container 41 and is used to heat the adhesive. The water bath 44 is equipped with a heating tube and a water level sensor. The water bath 44 indirectly and uniformly heats the adhesive in the upper adhesive container cavity, achieving precise temperature control and avoiding local overheating and performance degradation that may occur with direct heating. The upper cover 45 is detachably connected to the adhesive container 41, forming a semi-closed structure. A seal is provided between the upper cover 45 and the adhesive container 41 to reduce the escape of volatile organic compounds (VOCs) from the adhesive, improve the working environment, and reduce adhesive loss. The adhesive container 41 is equipped with an adhesive inlet 411 for replenishing adhesive. The adhesive container 41 is equipped with an adhesive level sensor 412 for real-time monitoring of the adhesive level. When the adhesive level is lower than a preset threshold, the control system automatically triggers a replenishment action to ensure continuous production.

[0032] Optionally, such as Figure 11 As shown, the fiber interlacing and laminating mechanism 05 includes a first laminating assembly 51 and a second laminating assembly 52, which are symmetrically arranged. The first laminating assembly 51 includes a support plate 511, a first insert drive member 512, and a plurality of first forming inserts 513. The support plate 511 is vertically arranged, and the plurality of first forming inserts 513 are horizontally arranged. One end of the plurality of first forming inserts 513 is connected to the support plate 511, and the first insert drive member 512 is connected to the support plate 511. The first insert drive member 512 is adapted to drive the support plate 511 to move back and forth in the horizontal direction. The second laminating assembly 52 includes a second insert drive member 522 and a plurality of second forming inserts 523. The other end face of the plurality of first forming inserts 513 is used to adsorb the coated forward sheet 120, and the other end face of the plurality of second forming inserts 523 is used to adsorb the coated reverse sheet 140. Specifically, the first insert rod drive 512 is driven by a servo motor via a ball screw and nut pair. The first raw material adsorption module 21 and the second raw material adsorption module 22 adsorb the coated forward and reverse sheets and enter the vacuum channel openings of the first forming insert rod 513 and the second forming insert rod 523. During stacking, under the action of the first insert rod drive 512 and the second insert rod drive 522, the first insert rod drive 512 drives the support plate 511 to move, thereby bringing the first forming insert rod 513 and the second forming insert rod 523 closer to each other, and stacking the coated forward sheet 120 and reverse sheet 140 alternately to form a complete honeycomb structure.

[0033] Optionally, the first stacking assembly 51 further includes a guide plate 514, which is vertically arranged and has multiple through holes for the first forming insert 513 to pass through. The first forming insert 513 has a vacuum channel, the opening of which is formed at the end of the first forming insert 513, and is connected to a negative pressure source. The first forming insert 513 is precision-machined from mold steel or other high-rigidity materials, possessing high-standard geometric tolerances. The guide plate 514 provides high-precision support and guidance for the movement trajectory of the first forming insert 513, preventing deviation during high-speed or high-load reciprocating motion and ensuring high alignment accuracy and positional stability. During stacking, the vacuum channel is connected to the negative pressure source, and the opening of the vacuum channel applies an adsorption force to the forward and reverse sheets, causing the sheets to adhere tightly to the surface of the first forming insert 513 and effectively expelling trapped air between the sheets and the underlying material, thereby ensuring the bonding quality after stacking.

[0034] In addition, the first lamination assembly 51 may also include a position calibration device 515, which includes a high-precision non-contact laser displacement sensor. The detection end of the laser displacement sensor is aligned with the preset calibration surface of the first forming insert 513. The detection signal of the laser displacement sensor is transmitted to the control device through a shielded cable, forming a closed-loop control circuit with the insert drive component 512 to realize an automated process of "detection-calculation-compensation".
