Description

Technical Field

[0001] This utility model relates to the field of electric bicycle manufacturing technology, and in particular to an electric bicycle production line scanning system. Background Technology

[0002] In the assembly and production of electric bicycles, it is typically necessary to collect relevant data during the assembly of key components such as the frame, motor, controller, and instruments, and then input this information into the Manufacturing Execution System (MES) for production management and quality traceability. Currently, this task is generally accomplished manually on the production line, with operators using handheld scanning devices to scan the markings on each component one by one. This manual scanning method has significant limitations in practical applications. First, scanning operations are greatly affected by human factors, and data omissions, errors, or duplicates can easily occur due to operational negligence, fatigue, or misjudgment, affecting the accuracy and completeness of the data. Second, the pace of manual scanning is difficult to synchronize perfectly with the production line rhythm, potentially becoming a bottleneck affecting overall production efficiency. In addition, there is usually a certain delay in the recording and transmission of scanned data, making it difficult to provide the MES system with real-time, continuous production line status information. These problems make the data collection stage of the production process a weak point in the quality management system, affecting the reliability of product lifecycle traceability and hindering further improvements in the automation and informatization level of the production line.

[0003] Therefore, there is an urgent need for an electric bicycle production line scanning system that can automate the collection of assembly data and adapt to changing production layouts and vehicle models. Utility Model Content

[0004] The purpose of this invention is to provide an electric bicycle production line scanning system to solve the problems existing in the prior art, enabling automated collection of assembly data and adapting to changing production layouts and vehicle models.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides a scanning system for an electric bicycle production line, including an assembly line with a frame assembly station, a motor assembly station, a controller assembly station, and an instrument assembly station arranged sequentially. It also includes a scanning assembly and a MES system terminal. The scanning assembly includes scanning units respectively disposed at the frame assembly station, motor assembly station, controller assembly station, and instrument assembly station, each scanning unit being communicatively connected to the MES system terminal. Each scanning unit includes a scanner and an adjusting bracket for mounting the scanner. Each adjusting bracket includes a support rod and a mounting arm, and each scanner is hinged to the end of the mounting arm.

[0007] As one embodiment, the upright of the adjusting bracket is a pneumatic lifting rod or an electric lifting rod, with a lifting stroke of 50cm to 100cm.

[0008] In one embodiment, the mounting arm and the upright pole, as well as the mounting arm and the scanner, are connected by universal joints.

[0009] As one embodiment, the scanning unit includes a protective cover located outside the lens of the scanner.

[0010] As one embodiment, a cleaning nozzle is provided inside the protective cover, and the spray direction of the cleaning nozzle is toward the lens surface of the scanner. The cleaning nozzle is connected to an air source through a pipeline.

[0011] As one embodiment, the protective cover is provided with an annular blow tube, which surrounds the lens of the scanner. An air hole is opened on the inner side of the annular blow tube. The annular blow tube is connected to an independent air source or shares the same air source with the cleaning nozzle.

[0012] As one embodiment, the length of the mounting arm is adjustable, and the mounting arm is rotatably connected to the upright.

[0013] As one implementation, it also includes a certificate printing control device, which is electrically connected to the MES system terminal and is used to receive a successful binding signal and activate the connected industrial printer.

[0014] As one implementation, the certificate printing control device includes an audible and visual alarm that is activated when a binding failure or error signal is received.

[0015] As one embodiment, the assembly line is a roller conveyor line or a plate chain conveyor line.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] This invention achieves fully automated collection and identity binding of core component assembly information by independently setting up scanning units at each assembly station and communicating with the MES system terminal in real time. This overcomes the low efficiency and error-prone nature of manual barcode scanning, providing a precise data foundation for product lifecycle traceability. Simultaneously, the modular bracket system with a pole and mounting arm, combined with an end-hinged design, gives each scanner multi-degree-of-freedom positioning capabilities. This allows for flexible adaptation to different station layouts and barcode positions on different vehicle models, effectively eliminating blind spots in fixed scanning and significantly improving scanning success rate and system adaptability to various production needs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this invention is to provide an electric bicycle production line scanning system to solve the problems existing in the prior art, enabling automated collection of assembly data and adapting to changing production layouts and vehicle models.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-3As shown, this utility model provides a scanning system for an electric bicycle production line, including an assembly line with frame assembly stations, motor assembly stations, controller assembly stations, and instrument assembly stations arranged sequentially. It also includes a scanning assembly and a MES system terminal. The scanning assembly includes scanning units 1 respectively located at the frame assembly station, motor assembly station, controller assembly station, and instrument assembly station. Each scanning unit 1 is communicatively connected to the MES system terminal. Each scanning unit 1 includes a scanner 2 and an adjusting bracket for mounting the scanner 2. Each adjusting bracket includes a pole 3 and a mounting arm 4, and each scanner 2 is hinged to the end of the mounting arm 4. It is understood that the MES system refers to the Manufacturing Execution System, used for real-time monitoring, data collection, and task scheduling management of the assembly line's production process. By independently setting up a scanning unit 1 at each assembly station and communicating with the MES system terminal in real time, the system achieves automatic collection and identity binding of core component assembly information throughout the entire process, overcoming the low efficiency and error-prone nature of manual scanning, and providing a precise data foundation for product lifecycle traceability. Meanwhile, the modular bracket with uprights 3 and mounting arms 4, combined with the end hinge design, enables each scanner 2 to have a multi-degree-of-freedom basic positioning capability. This allows it to flexibly adapt to the spatial layout of different workstations and the barcode positions of different vehicle models, effectively eliminating the blind spots of fixed scanning and significantly improving the scanning success rate and the system's adaptability to different production needs.

[0027] Preferably, the scanner 2 is mounted on a scanner mounting base, which is hinged to the end of the mounting arm 4. The hinge shaft of the scanner 2 is directly driven by a micro servo motor. The housing of the micro servo motor is fixed to the end of the mounting arm 4, and the output shaft is connected to the scanner mounting base. The micro servo motor is controlled by the MES system and can receive command signals and drive the scanner 2 to rotate precisely to a preset angle.

[0028] As one implementation method, the upright 3 of the adjustable support is a pneumatic lifting rod or an electric lifting rod with a lifting stroke of 50cm to 100cm to adapt to the height requirements of different work positions.

[0029] As one implementation, the mounting arm 4 is connected to the pole 3 and the scanner 2 via universal joints, enabling flexible adjustment at multiple angles and ensuring that the scanner 2 can be aligned with the target area.

[0030] Preferably, the universal joint includes a damping adjustment structure. After being adjusted to a suitable angle, the universal joint is locked by tightening the damping adjustment structure to prevent the scanner 2 from shifting its angle due to its own weight or slight vibration, thus ensuring the long-term stability of the scanning angle.

[0031] As one embodiment, the scanning unit 1 includes a protective cover 5, which is located outside the lens of the scanner 2 to protect the lens from physical damage and environmental pollution.

[0032] Preferably, the protective cover 5 is made of highly transparent polycarbonate, and the protective cover 5 is threadedly connected to the scanner 2 housing.

[0033] In one embodiment, a cleaning nozzle 6 is provided inside the protective cover 5. The cleaning nozzle 6 sprays towards the lens surface of the scanner 2, and the cleaning nozzle 6 is connected to an air source via a pipe. When there are stains on the lens surface of the scanner 2, the cleaning nozzle 6 is activated to remove the stains.

[0034] In one embodiment, an annular blowpipe 7 is provided inside the protective cover 5. The annular blowpipe 7 surrounds the lens of the scanner 2, and air holes are opened on the inner side of the annular blowpipe 7. The annular blowpipe 7 is connected to an independent air source or shares the same air source with the cleaning nozzle 6. When the scanner 2 is working, the annular blowpipe 7 forms an annular airflow barrier near the lens of the scanner 2 to prevent dust in the environment from adhering to the lens of the scanner 2.

[0035] Preferably, the cleaning nozzle 6 and the annular blowpipe 7 are connected to the same air source through an integrated air path control module. The integrated air path control module includes a main air inlet, and the air path is divided into two branches: one branch is connected to the cleaning nozzle 6 via a first solenoid valve and a first air pipe, and the other branch is connected to the annular blowpipe 7 via a second solenoid valve and a second air pipe.

[0036] Preferably, a first throttle valve and a second throttle valve are respectively provided at the outlet ends of the first solenoid valve and the second solenoid valve, for independently adjusting the airflow to the cleaning nozzle 6 and the annular blowpipe 7. The cleaning nozzle 6 is configured with a higher pressure pulsed airflow to achieve cleaning force, while the annular blowpipe 7 is configured with a lower pressure stable airflow to form a uniform air curtain and reduce noise and energy consumption.

[0037] Preferably, the annular blowpipe 7 is made of flexible silicone tubing and is fixed to the inner wall of the protective cover 5 by clamps. A series of air holes with a diameter of 0.3 to 0.5 mm are evenly opened on the annular blowpipe 7. The axis of the air hole forms a specific angle with the direction perpendicular to the plane where the blowpipe is located. Specifically, the central axis of the air hole is tilted 10 to 50 degrees away from the lens of the scanner 2 relative to the radial direction of the blowpipe, so that the airflow forms a trumpet-shaped air curtain in front of the lens of the scanner 2, which can effectively isolate the external dust.

[0038] As one implementation, the length of the mounting arm 4 is adjustable, and the mounting arm 4 is rotatably connected to the upright 3, further enhancing the flexibility of the scanner 2 position adjustment.

[0039] As one implementation, it also includes a certificate printing control device, which is electrically connected to the MES system terminal and is used to receive a successful binding signal and activate the connected industrial printer to realize automatic printing of the certificate.

[0040] As one implementation, the certificate printing control device includes an audible and visual alarm that is activated when it receives a signal of binding failure or error, promptly alerting the operator to handle the abnormal situation.

[0041] As one implementation method, the assembly line is a roller conveyor or a plate chain conveyor to ensure that the electric bicycle is transported smoothly during the assembly process.

[0042] Preferably, for roller conveyor lines or plate chain conveyor lines, a stopper or positioning pin is added to each scanning station. When the electric bicycle arrives at the station, the vehicle is accurately stopped and positioned in the preset position, ensuring that the barcode on the vehicle body and components can be stably within the effective field of view of the scanner 2, thus effectively ensuring the success rate of scanning.

[0043] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
