Description

Technical Field

[0001] The present invention relates to the field of inflatable surfboard production, and in particular to a production process of inflatable surfboards. Background Art

[0002] A surfboard is a piece of sports equipment that people use for surfing.

[0003] The conflict between mold adaptability and production efficiency: Traditional processes use fixed-specification molds to produce surfboards, requiring separate molds for different sizes. This results in high mold costs and long replacement cycles, making it impossible to meet high-end market demands. Furthermore, the mold reuse rate is low, leading to a surge in costs when producing small batches of customized surfboards.

[0004] Quality fluctuations due to the separation of multiple processes: Cutting, printing, and sealing are completed independently. For example, traditional cutting requires transfer to the printing stage, which can easily cause board deformation. Single heat sealing has a high leakage rate at an inflation pressure of 0.3-0.5 bar, and the surface consistency is poor when manually attaching the anti-slip mat, resulting in insufficient friction on the surfboard surface.

[0005] Lack of intelligent functions and delayed detection: Traditional processes cannot implant smart accessories with pressure sensors during the production process, users cannot monitor tire pressure in real time, and air leak detection relies on manual visual inspection, resulting in a high missed detection rate.

[0006] Therefore, it is necessary to provide an inflatable surfboard production process to solve the above technical problems. Summary of the Invention

[0015] S4, three-dimensional sealing compensation and inflation detection:

[0016] Execute the "pre-pressing-inflation-secondary sealing" process: After the mold pre-presses the seam, it is inflated to 0.3-0.5 bar. The robot sprays liquid silicone to fill the tiny leaks, improving the airtightness to 3 times that of the traditional process. After inflation, the leak test is immediately carried out, and the leak point is marked in real time by the pressure sensor;

[0017] S5. Adaptive decoration and edge reinforcement: The leather pressing machine is equipped with a visual positioning system to automatically identify the curvature of the surfboard surface. The elastic pressing head simultaneously completes the anti-slip pad lamination, fiberglass strip reinforcement and TPU edging, replacing traditional manual operations. At the same time, it also performs cosmetic treatment on the edges to enhance the aesthetics.

[0021] S8. Folding packaging and storage: Fold the finished surfboards and package them. Before packaging, confirm that the smart functions are normal.

[0022] Preferably, the visual recognition system of the five-axis laser cutting in S2 uses a CCD camera and a deep learning algorithm to perform real-time contour scanning and path planning on special-shaped parts such as wavy edges.

[0023] Preferably, the liquid silicone rubber used for the secondary seal in S4 is an addition-type room temperature vulcanized silicone rubber, which has a Shore hardness of 40-50A and an elongation at break of ≥300% after curing.

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] First embodiment

[0041] A process for producing an inflatable surfboard comprises the following steps:

[0042] S1. Construction and preparation of parametric mold library: Establish a digital mold library for basic plate types, adopt a retractable frame structure, and achieve dynamic adjustment of length and curvature through servo motor drive to adapt to the substrate of EVA foam material;

[0043] Synchronously prepare traditional fixed molds as a supplement to standardized production;

[0044] S2, Laser-Mechanical Collaborative Cutting and Printing:

[0045] Standardized parts are punched by molds, and special-shaped parts are cut by five-axis laser. After the cutting is completed with the help of the visual recognition system, the surface of the plate is immediately digitally printed, and the UV curing process is used to improve the wear resistance of the pattern.

[0046] S3. Pulse heat sealing and accessories assembly:

[0047] The HQ-5KWPro multi-station heat sealing machine is used to install the air valve and tail fin accessories by heat sealing at a set temperature of 180℃±5℃ and a pressure of 0.8MPa. The machine automatically adjusts the parameters based on real-time feedback of temperature and pressure data to ensure the connection strength of the accessories.

[0048] S4, three-dimensional sealing compensation and inflation detection:

[0049] Execute the "pre-pressing-inflation-secondary sealing" process: After the mold pre-presses the seam, it is inflated to 0.3-0.5 bar. The robot sprays liquid silicone to fill the tiny leaks, improving the airtightness to 3 times that of the traditional process. After inflation, the leak test is immediately carried out, and the leak point is marked in real time by the pressure sensor;

[0050] S5. Adaptive decoration and edge reinforcement: The leather pressing machine is equipped with a visual positioning system to automatically identify the curvature of the surfboard surface. The elastic pressing head simultaneously completes the anti-slip pad lamination, fiberglass strip reinforcement and TPU edging, replacing traditional manual operations. At the same time, it also performs cosmetic treatment on the edges to enhance the aesthetics.

[0051] S6. Smart Accessory Implantation and Functional Testing: The pressure sensor and Bluetooth module are embedded through the reserved interface of the mold to realize the real-time tire pressure monitoring function. After implantation, a full functional test is performed to ensure the sensor accuracy and communication stability.

[0052] S7. Appearance beautification and secondary inspection:

[0053] Repeat the printing process in S2 to beautify the details, and use the leather pressing machine to complete the final decoration. Use the AI ​​quality inspection system to conduct a second inspection of cutting accuracy, heat sealing quality, and sealing effect;

[0054] S8. Folding packaging and storage: Fold the finished surfboards and package them. Before packaging, confirm that the smart functions are normal.

[0055] The visual recognition system for five-axis laser cutting in the S2 uses a CCD camera and a deep learning algorithm to perform real-time contour scanning and path planning for irregular shapes such as wavy edges.

[0056] The liquid silicone rubber used for the secondary seal in S4 is an addition-type room temperature vulcanized silicone rubber, which has a Shore hardness of 40-50A and an elongation at break of ≥300% after curing.

[0057] The pressure sensor in the S6 has a measurement range of 0-1 bar, an accuracy of ±0.01 bar, and communicates with the terminal device via the Bluetooth protocol.

[0058] Principle of dynamic mold adaptation: The servo motor drives the mold frame to extend and retract through a rack and pinion mechanism. The guide rails on both sides move synchronously when the length is adjusted. The curvature adjustment is achieved through the curved guide rail slider. The AI ​​algorithm automatically calculates the optimal mold parameters based on the plate size to avoid stress concentration.

[0059] Laser-printing linkage principle: After cutting is completed, the conveyor belt transports the plate to the printing station at a speed of 0.5m / s. The UV lamp group irradiates the plate in a follow-up manner, and the ink cures within 1 second, reducing deformation caused by transportation.

[0060] The principle of three-dimensional sealing compensation: the initial mold pre-compression makes the seams initially bonded (the airtightness reaches 80% of the traditional process). After inflation, micro-leakage points appear due to the internal and external pressure difference. The robot locates according to the pressure sensor data and sprays liquid silicone to fill the gap. After curing, it forms a "mechanical pre-compression + chemical sealing" double protection.

[0061] Intelligent detection principle: The pressure sensor collects tire pressure data in real time and sends it to the terminal APP via Bluetooth. When the pressure drop rate is greater than 0.01bar / minute, the APP triggers an audible and visual alarm to prompt the user to check for leaks.

[0062] Compared with related technologies, the inflatable surfboard production process provided by the present invention has the following beneficial effects:

[0063] The present invention provides a production process for an inflatable surfboard.

[0064] Improved mold adaptability and production efficiency: Through a parametric mold library and a retractable frame structure, dynamic adjustment of mold length and curvature is achieved, while retaining traditional fixed molds to meet the needs of large-scale standardized production, balancing the contradiction between customization and cost control;

[0065] Innovations in intelligent functions and detection systems: Implanted pressure sensors and Bluetooth modules enable real-time tire pressure monitoring and APP alarms, addressing the lack of intelligence in traditional processes. Three-dimensional sealing compensation technology reduces missed detection rates through the "pre-pressurization-inflation-secondary sealing" process, combined with an AI quality inspection system.

[0066] Automated production reduces labor costs: The visual positioning system and elastic pressing head of the leather pressing machine replace manual operation, and the consistency of edge reinforcement and anti-slip pad fitting is significantly improved.

[0073] The detector body 21 has a built-in MCU chip, which collects tire pressure data at a frequency of 1Hz and exports it to the computer through the RS485 interface. The software automatically calculates the leakage rate and generates a CSV format test report, which supports code scanning and tracing.

[0074] A temperature sensor is set inside the detection box 1. When the ambient temperature changes by more than 5°C, the system automatically corrects the pressure data to avoid misjudgment due to temperature fluctuations.

[0075] The working principle of the inflatable surfboard production process provided by the present invention is as follows:

[0076] During use, when performing gas detection on an inflatable surfboard, first push the movable plate 51 toward both sides of the detection box 1 to move to both sides under the action of the movable block 53 and the movable groove 54.

[0077] Then start the air pump inside the detector body 2 to inflate the surfboard to 0.4 bar, and the system automatically records the pressure decay data.
