It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0087] Composite panels with warp and weft orientation, due to their inherent characteristics—specifically, the warp and weft arrangement of the panels—possess numerous advantages such as high strength in both warp and weft directions, corrosion resistance, light weight, and recyclability. They have already replaced traditional materials like steel, aluminum, fiberglass, and wood in many fields, including container shipping, oil and gas transportation, and building materials. Solid fiberglass composite panels are experiencing rapid growth and are being widely adopted in container side panels and new energy vehicles. They not only help reduce production and usage costs and achieve lightweight installation but are also environmentally friendly and recyclable, aligning with the concept of green development and gaining market favor. Warp and weft-oriented composite panels are also the basic material for other composite panels; many composite panels are formed by splicing together basic warp and weft-oriented panels.

[0088] This application introduces automated equipment to reduce manual labor and improve the efficiency and uniformity of horizontally placed sheets. Based on existing production equipment, it provides a highly automated and versatile composite new material production line for feeding, sorting, positioning and precise placement of horizontal sheets.

[0089] Reference Figure 1 , Figures 5-6This application provides a strip production system for splicing and stitching sheets 600 into strip 700, reducing manual operation, improving the automation level of the production line, and ensuring stable and consistent quality of the output strip 700. The strip 700 production system provided by this application enables efficient, precise, and stable production of strip 700, improving production efficiency and reducing costs. In this application, the sheet 600 and the strip 700 have different aspect ratios, and multiple sheets 600 are spliced ​​together to form the strip 700.

[0090] In this application, the strip 700 production system includes a first material preparation unit 100. The first material preparation unit 100 realizes the splicing and stitching of the sheet 600.

[0091] The first material preparation unit 100 includes a support platform 110, a conveying roller group, and a buffer roller group arranged sequentially along the conveying direction of the sheet 600.

[0092] In some embodiments of this application, the support platform 110 is configured in two sets, one for use and one as a spare. The spare support platform 110 assembly allows for switching as needed, ensuring uninterrupted supply of the sheet 600 during production and guaranteeing production continuity and stability. The support platform 110 is used to supply the sheet 600 to the conveyor roller assembly. The sheet 600 is stacked along the height direction within the support platform 110.

[0093] Optionally, a first robotic arm is provided near the support platform 110. The first robotic arm is used to transfer the sheet 600 to a specific position on the conveyor roller assembly. By setting up the first robotic arm, the automatic transfer of the sheet 600 is realized, reducing manual operation and ensuring the precise positioning of the sheet 600 during the production process. This reduces errors and deviations that may be introduced by human operation and improves the accuracy and stability of the production process.

[0094] In some embodiments of this application, the conveyor roller group includes a third conveyor roller group 123, a first conveyor roller group 121, and a second conveyor roller group 122 arranged sequentially along the conveying direction. A first robotic arm transfers the sheet 600 to the third conveyor roller group 123, placing the sheet 600 at predetermined intervals and conveying it at a predetermined speed within the third conveyor roller group 123. The first robotic arm can quickly and accurately transfer the sheet 600 from the support platform 110 to the third conveyor roller group 123, improving the efficiency and speed of sheet 600 transfer. Through an advanced control system and sensors, the robotic arm can achieve precise positioning and placement of the sheet 600, ensuring the smooth execution of subsequent processes such as sewing. Manual operation may lead to errors and inconsistencies, while the robotic arm can repeatedly perform the same task according to a preset program, reducing errors caused by human factors and ensuring the consistency of the manufactured products.

[0095] A first detection device 140 is installed between the third conveyor roller group 123 and the first conveyor roller group 121. The first detection device 140 is used to detect the sheet 600 and send the unqualified sheet 600 to the abnormal product storage area 141. Optionally, a second robotic arm is also provided to transfer the unqualified sheet 600 to the abnormal product storage area 141, realizing automated sorting and processing, avoiding the mixing of unqualified and qualified products, and ensuring product quality. Optionally, the first detection device 140 adopts integrated online detection, which uses a high-precision camera to dynamically scan the surface of the sheet 600 in operation, determine whether there are surface defects or flaws, and then determine whether the sheet 600 is a qualified or unqualified product. The abnormal product signal is transmitted to the second robotic arm, which transfers the unqualified sheet 600 to the abnormal product storage area 141 for palletizing and storage.

[0096] The first and second robotic arms described above can be constructed as robotic arms with multiple sets of vacuum suction cups that can vertically pick up and move horizontally, thereby enabling the vacuum suction cups to pick up and release sheet 600.

[0097] Alternatively, the control unit can calculate the speed of the conveyor and the material on the preparation platform based on machine vision (such as a camera), thereby controlling the first and second robotic arms to accurately follow the material's movement according to the speed and place the sheet 600 at the correct position.

[0098] In this application, a sewing assembly 130 is also provided. A first conveyor roller group 121 is used to convey qualified sheets 600 placed at predetermined intervals at a first predetermined speed; a second conveyor roller group 122 is disposed downstream of the first conveyor roller group 121. The sewing assembly 130 is used to sew adjacent sheets 600 to form a strip 700, which is conveyed by the second conveyor roller group 122 at a second predetermined speed. In this application, the qualified sheets 600 continue to be transported forward by the first conveyor roller group 121, and after being sewn by the sewing assembly 130, continue to be transported forward by the second conveyor roller group 122. Optionally, the sewing assembly 130 is disposed in the gap between the first conveyor roller group 121 and the second conveyor roller group 122. When the front end of the unsewn sheet 600 is conveyed to the gap by the first conveyor roller, the front end of the sewn sheet 600 is conveyed to its rear end in the gap by the second conveyor roller. The rear end of the upstream sheet 600 is opposite to the front end of the downstream sheet 600, and the sewing assembly 130 sewn the two sheets 600 together. Optionally, during sewing, the running speed of both the first conveyor roller group 121 and the second conveyor roller group 122 is 0. After sewing, the speed of the first conveyor roller group 121 is slightly greater than that of the second conveyor roller group 122 to reduce the gap between adjacent sheets 600, thereby achieving better sewing.

[0099] like Figure 2As shown, in some embodiments of this application, the sewing assembly 130 includes a glue spray head 131 and a pressure roller 132. The glue spray head 131 is used to spray glue between adjacent sheets 600. The pressure roller 132 is used to press against the sheets 600 to press the adjacent sheets 600 together after glue spraying. Optionally, the glue spray head 131 is disposed in the gap between the first conveyor roller group 121 and the second conveyor roller group 122, and the glue spray head 131 is higher than the first conveyor roller group 121 and the second conveyor roller group 122. The glue spray head 131 can automatically spray glue into the gap between adjacent sheets 600. By precisely controlling the glue spraying position and amount, a uniform adhesive layer is formed in the gap between the sheets 600, realizing automated bonding of the sheets 600, which is beneficial to improving product quality and stability. The rotation axis of the pressure roller 132 is perpendicular to the gap, and the pressure roller 132 is higher than the first conveyor roller group 121 and the second conveyor roller group 122. The combined use of the glue spray head 131 and the pressure roller 132 enables effective pressing and bonding of adjacent sheets 600, improving the bonding strength and stability of the strip 700. Preferably, the pressure roller 132 is a stainless steel mirror roller. The highly smooth surface of the stainless steel mirror roller helps ensure that the pressure roller 132 does not leave scratches or marks when contacting the strip 700, maintaining the quality of the product surface. The mirror-finished stainless steel surface can also effectively reduce adhesive adhesion, avoiding contamination or damage to the sheet 600 during production. In this embodiment, the sewing assembly 130 is positioned by a servo motor, and the lifting of the pressure plate and pressure roller 132 is controlled by a cylinder. When sewing is in operation, the cylinder descends while simultaneously sending a signal to the glue machine, ensuring that glue is dispensed during sewing.

[0100] Based on the above embodiment, the sewing assembly 130 is movably disposed between the first conveying roller group 121 and the second conveying roller group 122 along a first direction, which is perpendicular to the conveying direction of the sheet 600. Specifically, the glue spray head 131 and the pressure roller 132 are movably disposed in the gap along the first direction, thereby enabling the adhesive to be evenly sprayed between the first conveying roller group 121 and the second conveying roller group 122.

[0101] Based on the above embodiments, the sewing assembly 130 further includes a first pressure plate 1331 and a second pressure plate 1332, with a glue spraying gap 1333 between the first pressure plate 1331 and the second pressure plate 1332; wherein, the glue spraying head 131 corresponds to the glue spraying gap 1333, and along the conveying direction of the sheet 600, the first pressure plate 1331 and the second pressure plate 1332 are respectively located upstream and downstream of the glue spraying head 131. That is, the first pressure plate 1331 and the second pressure plate 1332 are respectively located on both sides of the glue spraying gap 1333, the first pressure plate 1331 presses against the sheet 600 on the first conveying roller group 121, and the second pressure plate 1332 presses against the sheet 600 on the second conveying roller group 122. Optionally, the first pressure plate 1331 and the second pressure plate 1332 are integrally formed. During the bonding process, the first pressure plate 1331 and the second pressure plate 1332 provide effective pressure resistance, ensuring that the gaps between the sheets 600 are flat and that the adhesive can be evenly distributed on the contact surfaces of the sheets 600. Optionally, the spray gap 1333 between the first pressure plate 1331 and the second pressure plate 1332 is larger than the gap between adjacent sheets 600 to avoid unnecessary waste of adhesive.

[0102] Optionally, both the first pressure plate 1331 and the second pressure plate 1332 are provided with rolling elements 134, which press against the sheet 600. The rolling elements 134 are bearings. Using rolling elements 134 provides a smoother and more stable pressing force and reduces friction generated during the pressing process, thus reducing energy loss and improving equipment operating efficiency. For example, the rolling elements 134 are symmetrically arranged on both sides of the glue spraying gap 1333 to ensure that the sheet 600 is subjected to uniform force during production. Furthermore, along the first direction, the rolling elements 134 are arranged on both sides of the glue spraying head 131 so that the sheet 600 on both the front and rear sides of the glue spraying head 131's moving direction is pressed, ensuring the effectiveness of glue spraying.

[0103] like Figure 3 As shown, in some embodiments of this application, two stitching components 130 are provided. One stitching component 130 is movable between the middle portion of the gap and the first end, and the other stitching component 130 is movable between the middle portion of the gap and the second end. The pressure roller 132 is closer to the middle portion of the gap than the glue spray head 131. This allows the sheet 600 to be evenly bonded on both sides along its width, helping to ensure the accuracy and stability of the glue spraying and pressing operations, and improving product quality.

[0104] like Figure 4As shown, in some embodiments of this application, the stitching assembly 130 also includes a feeding unit for providing a stable supply of adhesive to the spray nozzle 131. An integrated feeding unit is generally easier to maintain and clean, helping to keep the equipment in good condition and extend its service life; the feeding unit can accurately control the amount of adhesive required by the spray nozzle 131, avoiding over- or under-adhesion, reducing material waste, thereby ensuring that each sheet 600 can be effectively stitched together, improving the quality of the final product.

[0105] The feeding unit includes a material tank 135, a mixing device 137, a heating chamber 138, a feeding pump 139, and a dispensing pipe 136 connected in sequence. The material tank 135, mixing device 137, heating chamber 138, and feeding pump 139 are arranged from high to low, and are transported by gravity to achieve continuous adhesive supply. In this embodiment, multiple material tanks 135 are provided, each containing different types of adhesive. The mixing device 137 can thoroughly mix different types of adhesive according to a set ratio. Optionally, a discharge device is provided at the bottom of the mixing device 137 to determine the allowable discharge by detecting the height of the material. The heating chamber 138 is equipped with a plate heater to melt the material and form an adhesive of a preset form. The dispensing pump 139 uses frequency control via a frequency converter to control the dispensing speed. Optionally, the dispensing pipe 136 is a high-temperature resistant flexible pipe. Multiple heating wires are wound around the outside of the dispensing tube 136, and a temperature controller is used to ensure that the temperature inside the entire dispensing tube 136 is uniform.

[0106] In some embodiments of this application, the buffer roller group includes a first buffer roller group 151 and a second buffer roller group 152. The first buffer roller group 151 is located downstream of the second conveyor roller group 122 and is lower than the second conveyor roller group 122 along the height direction of the production system. The first buffer roller group 151 is movable along the height direction. The second buffer roller group 152 is located downstream of the first buffer roller group 151 and is higher than the first buffer roller group 151. By setting the first buffer roller group 151, when changing materials, the height difference between the first buffer roller group 151 and the conveyor roller group is small, so the equipment can continue to convey materials without stopping. After the subsequent materials are in place, the height difference between the first buffer roller group 151 and the conveyor roller group is larger, so as to realize the material conveying, buffering and storage, and improve the continuity and stability of the production line.

[0107] Optionally, the first material preparation unit 100 further includes a second detection device 153, which is used to detect the position of the first buffer roller group 151. The second detection device 153 consists of multiple sets of through-beam photoelectric devices, which are set according to the PLC program as the lower limit for full material, the upper limit for insufficient material, the guide conveyor position, and the alarm conveyor position. When the position of the first buffer roller group 151 reaches the alarm conveyor position, the second detection device 153 can issue a warning signal to promptly notify the operator for handling, thereby avoiding production interruption and material shortage. This effectively avoids production interruptions caused by material supply problems and ensures the normal supply of materials. It improves the degree of automation, production stability, and safety.

[0108] In some embodiments of this application, a second material preparation unit 200 is also included, which is used to release continuous substrate sheets. The second material preparation unit 200 consists of multiple sets of unwinding trolleys arranged in parallel along the production line direction. A magnetic powder brake device is installed on the unwinding trolley to maintain constant tension output of the substrate sheets. The material roll is hoisted and placed on the unwinding trolley, and then transported to a designated loading positioning point via a specially designed guide rail of the loading conveyor. The unwinding trolley is axially slidably mounted on a base, and a lead screw is provided between the trolley and the base. The lead screw, in conjunction with a hand-cranked sprocket, is used to adjust the axial position of the unwinding trolley.

[0109] In some embodiments of this application, the first material preparation unit 100 and the second material preparation unit 200 are spaced apart in the height direction of the production system, which can make more efficient use of space to stack the strip 700 with the backing sheet to form a continuous composite strip. By stacking the strip 700 and the backing sheet, a continuous composite production process can be realized, improving production efficiency and continuity.

[0110] In some embodiments of this application, a shaping unit 300 is also included. The shaping unit 300 is located downstream of the first material preparation unit 100 and the second material preparation unit 200, and is used to shape the continuous composite strip to improve product consistency and stability. The conveying speed of the shaping unit 300 is synchronized with the conveying speed of the second material preparation unit 200 and is in a certain proportion to avoid phenomena such as material stretching or piling.

[0111] The shaping unit 300 includes a thermal bonding device, which comprises a preheating zone, a hot die zone, and a cold die zone arranged sequentially along the conveying direction of the strip 700. Through continuous processing in the preheating zone, hot die zone, and cold die zone, the laminated strip 700 and the backing sheet are ensured to bond and shape at a suitable temperature, thereby improving bonding strength and product quality. The thermal bonding device is used to hot-press and shape the laminated strip 700 and the backing sheet into a continuous composite strip. The thermal bonding device is constructed with an upper die portion and a lower die portion, and the minimum distance between the upper die portion and the lower die portion is adjustable, for example, adjusting the spacing of the composite belt or composite steel strip, so that the equipment can be used to process strips 700 of different thicknesses. The thermal bonding device can be set with different bonding temperatures and the distance between the upper die portion and the lower die portion according to the material characteristics. The entire thermal bonding process is automated and continuous, reducing manual intervention and production interruptions, thereby improving production efficiency.

[0112] Optionally, the shaping unit 300 further includes a hot air blower and a pressure roller 132, which are located upstream of the thermal laminating device to preheat and compress the stacked strip 700 and the backing sheet. Compressing the blank by the pressure roller 132 helps to enhance the adhesion between the strip 700 and the backing sheet, reduce bubbles and wrinkles, and provide a better foundation for subsequent thermal laminating processes.

[0113] In some embodiments of this application, a cutting unit 400 is also included, which is disposed downstream of the shaping unit 300. The cutting unit 400 is used to cut the continuous composite strip. By processing the continuous composite strip into suitable dimensions, such as cutting it to a suitable width, the cutting unit 400 ensures the dimensional consistency and edge neatness of the product.

[0114] The cutting unit 400 includes a traction roller group 410 and a longitudinal cutting device 420. The traction roller group 410 is located downstream of the shaping unit 300 and provides a stable traction force for the continuous composite strip, pulling the continuous composite strip to the cutting unit 400. The longitudinal cutting device 420 is used to cut the edges on both sides of the continuous composite strip to ensure that the product dimensions and appearance meet quality standards.

[0115] The cutting unit 400 also includes a waste edge collection device, which is used to collect the waste edges cut by the longitudinal cutting device 420. The waste edge collection device is set on both sides of the continuous composite strip along the width direction, automatically collecting the waste edges generated during the cutting process, which can keep the production site clean and improve the quality of the working environment.

[0116] In some embodiments of this application, a winding unit 500 is also included. The winding unit 500 is disposed downstream of the cutting unit 400 and is used to wind up the continuous composite strip.
