Description

Technical Field

[0001] This utility model relates to the field of solar cell module laminator module discharge conveying technology, and more specifically to a multi-layer roller conveying structure. Background Technology

[0002] In the field of photovoltaic laminator material conveying, most existing conveying equipment adopts a single-layer conveying structure. While this single-layer conveying equipment can meet the basic conveying requirements in traditional laminators, its conveying method has significant limitations when facing multi-layer laminators, making it difficult to adapt to the high efficiency and high capacity requirements of modern photovoltaic production. Specifically, this is manifested in the following aspects:

[0003] Low transmission efficiency: Single-layer transmission equipment cannot handle the discharge needs of multiple layers of components at once when processing the output of multi-layer laminators. Each layer of components needs to be transported separately, resulting in the discharge process being performed multiple times, increasing the cycle time. This inefficient transmission method severely restricts the improvement of production efficiency, especially in large-scale production environments, where its impact on the overall production cycle is particularly significant.

[0004] Material blockage is a common problem: When multiple layers of modules are discharged simultaneously, single-layer conveying equipment cannot process them all at once, leading to module accumulation. This accumulation not only damages the photovoltaic modules but also disrupts production continuity, causing production line downtime, increasing maintenance costs, and raising the risk of production delays.

[0005] Poor adaptability: Existing single-layer conveyor equipment cannot be flexibly adjusted according to the specific number of layers and discharge conditions of multi-layer laminators. The number of layers and discharge rhythm of multi-layer laminators may vary due to production needs, but single-layer conveyor equipment cannot meet these diverse production requirements. This lack of flexibility means that companies need to configure multiple sets of conveyor equipment when dealing with multi-layer laminators of different specifications, increasing equipment costs and management complexity.

[0006] Insufficient cooling efficiency: During the production of photovoltaic modules, the laminated modules need to be cooled promptly to prevent thermal damage. However, single-layer transmission equipment typically lacks effective cooling devices, making it impossible to cool the modules uniformly during transmission. This can not only affect the quality of the modules but may also cause them to deform or be damaged due to excessively high temperatures during transmission.

[0007] Lack of detection capabilities: Most existing single-layer transmission equipment lacks intelligent detection functions and cannot monitor the transmission status of components in real time. Under the complex operating conditions of multi-layer laminators, this may lead to component transmission errors or omissions, thereby affecting product quality and production efficiency.

[0008] In summary, traditional single-layer transmission equipment can no longer meet the material conveying requirements of multi-layer laminators. With the rapid development of the photovoltaic industry, the requirements for production efficiency and product quality are becoming increasingly stringent. There is an urgent need for a new transmission structure that can adapt to the material conveying conditions of multi-layer laminators to improve discharge efficiency, avoid material blockage, meet the production requirements of multi-layer laminators, and simultaneously reduce production costs and equipment management complexity. Utility Model Content

[0009] In view of this, the present invention provides a multi-layer roller conveying structure, which aims to solve the above-mentioned technical problems.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A multi-layer roller conveying structure includes a frame and a multi-layer conveying mechanism disposed on the frame. Each layer of the conveying mechanism includes a plurality of drive sprocket rollers rotatably connected to the frame. The structure also includes a number of drive mechanisms equal to the number of conveying mechanisms, each drive mechanism being used to individually drive each layer of the conveying mechanism. The drive mechanism includes:

[0012] A drive motor, which is mounted on the frame;

[0013] The transmission chain comprises multiple transmission chains, with the ends of adjacent transmission sprockets and rollers connected by the transmission chain. The power output end of the drive motor is connected to the end of the outermost transmission sprocket and roller by the transmission chain.

[0014] Through the above technical solution, the multi-layer transmission structure of this utility model can simultaneously handle the discharge needs of multi-layer components. Compared with traditional single-layer transmission equipment, it greatly reduces the discharge cycle time and significantly improves production efficiency. The multi-layer transmission mechanisms can operate independently, avoiding the component accumulation problem caused by the inability of single-layer transmission equipment to handle multiple layers simultaneously. This ensures production continuity and reduces the risk of production line downtime and maintenance costs due to material blockage. It can be flexibly configured according to the specific number of layers and discharge conditions of the multi-layer laminator, meeting the production needs of different specifications of multi-layer laminators and reducing the cost and management complexity of equipment configuration for enterprises.

[0015] Preferably, in the above-mentioned multi-layer roller conveying structure, the driving mechanism further includes a reducer fixed on the frame. The power input end of the reducer is connected to the power output shaft of the drive motor, and the power output end of the reducer is connected to the end of the transmission sprocket roller at the outermost end via the transmission chain. The addition of the reducer allows for adjustment of the motor speed, making the speed of the transmission sprocket roller more precise, thereby achieving accurate control of the component transmission speed and better adapting to the transmission speed requirements of different production stages. The reducer can increase the output torque, enhance the driving capability of the driving mechanism, ensure that the transmission sprocket roller can stably drive the transmission of heavier components, and improve the load-bearing capacity of the equipment. Through the action of the reducer, the required output speed and torque can be achieved at a lower motor speed, thereby reducing the motor load, extending the motor's service life, and improving the reliability and stability of the equipment.

[0016] Preferably, in the above-described multi-layer roller conveying structure, the frame further includes a conveying frame for supporting each layer of the drive sprocket rollers. The conveying frame provides stable support for each layer of drive sprocket rollers, ensuring that the drive sprocket rollers do not wobble or shift during operation, thus improving the stability and reliability of the entire conveying structure and guaranteeing the smoothness of component transmission. The conveying frame makes the installation of the drive sprocket rollers more convenient, and also facilitates the maintenance and repair of the drive sprocket rollers and related components, reducing equipment maintenance costs and time. The conveying frame can be rationally designed according to the overall structure of the frame, making the multi-layer conveying mechanism more compact in space, making full use of limited space, and improving the space utilization rate of the equipment.

[0017] Preferably, in the above-mentioned multi-layer roller conveyor structure, the conveyor frame has connecting holes, and the uprights of the frame have strip holes corresponding to the connecting holes. The conveyor frame is vertically adjustable to the uprights by bolts passing through the connecting holes and the strip holes. Through the cooperation of the bolts and the strip holes, the height of the conveyor frame can be vertically adjusted according to actual production needs, allowing each layer of the conveyor mechanism to adapt to components of different heights or different production conditions, enhancing the flexibility and adaptability of the equipment. This adjustable connection method is simple and quick to operate, enabling the height adjustment and positioning of the conveyor frame to be completed in a short time, improving the adjustment efficiency of the equipment and reducing production downtime caused by equipment adjustments. Different multi-layer laminators may have different layer spacings; the vertically adjustable conveyor frame can better adapt to various different equipment and process requirements, making this conveyor structure more widely applicable.

[0018] Preferably, in the above-mentioned multi-layer roller conveyor structure, a support block is fixed on the column, and a support bolt is threaded onto the support block. The top end of the support bolt abuts against the bottom surface of the conveyor frame. The abutment between the support bolt and the bottom surface of the conveyor frame provides additional support force, further enhancing the stability of the conveyor frame. Especially after the height of the conveyor frame is adjusted, it effectively prevents the conveyor frame from sinking or deforming due to gravity or external forces, ensuring long-term stable operation of the equipment. By rotating the support bolt, the height of the conveyor frame can be finely adjusted to achieve more precise positioning, resulting in higher levelness and height accuracy for each layer of the conveyor mechanism. This ensures that components will not jam or be damaged during transmission due to unevenness in the conveyor mechanism. A stable support structure reduces additional stress and wear on components such as the transmission sprockets, rollers, and drive mechanism caused by the shaking or deformation of the conveyor frame, thereby extending the overall service life of the equipment and reducing replacement costs.

[0019] Preferably, in the above-mentioned multi-layer roller conveying structure, the end of the transmission sprocket roller used for driving the transmission chain has a gear, and the transmission chain has teeth that mesh with the gear. The meshing transmission method of the gear and teeth enables precise power transmission, ensuring that the rotation of the transmission sprocket roller and the output of the drive motor maintain a strict synchronous relationship, improving the accuracy and stability of component transmission, and avoiding component position deviations caused by transmission errors. Gear transmission has high transmission efficiency, enabling more effective transmission of the power from the drive motor to the transmission sprocket roller, reducing energy loss, improving the energy utilization efficiency of the equipment, and reducing energy consumption. The meshing structure of the gear and teeth is relatively stable, and slippage or transmission failure is less likely to occur under normal operating conditions, improving the reliability of the entire drive system and reducing equipment downtime caused by transmission failures.

[0020] Preferably, in the above-described multi-layer roller conveyor structure, the drive mechanisms of each layer of the conveyor are arranged alternately on both sides of the frame. This staggered arrangement of drive mechanisms fully utilizes the space on both sides of the frame, avoiding the space congestion caused by concentrated drive mechanism placement, making the overall equipment structure more compact and saving floor space. The staggered arrangement of drive mechanisms also ensures more even force distribution on both sides of the frame, preventing frame deformation or displacement due to excessive force on one side, improving the overall balance and stability of the equipment, and extending the service life of the frame. Furthermore, the dispersed arrangement of drive mechanisms on both sides of the frame facilitates heat dissipation, avoiding localized overheating caused by multiple drive mechanisms concentrated together, improving the heat dissipation effect of components such as the drive motor and reducer, and further enhancing the reliability of the equipment.

[0021] Preferably, in the above-described multi-layer roller conveyor structure, a cooling fan assembly is installed at the bottom of the frame, and the cooling fan assembly is located below the multi-layer conveyor mechanism. The cooling fan assembly can continuously cool the photovoltaic modules during the conveying process, preventing thermal damage, deformation, or breakage due to excessive temperature, thus improving the quality and performance of the modules and meeting the cooling requirements during photovoltaic module production. Timely cooling of the modules can shorten the cooling time, allowing them to proceed to the next production stage more quickly, thereby improving the efficiency of the entire production process and reducing production delays caused by excessively long cooling times.

[0022] Preferably, in the aforementioned multi-layer roller conveyor structure, a photoelectric detection component is installed on the frame to detect the entry and exit of components from the conveyor mechanism. The photoelectric detection component can monitor the entry and exit status of components in real time, enabling intelligent detection of the component conveying process and timely detection of abnormalities such as missing components or positional deviations, thereby improving the automation and management level of production. Real-time monitoring by the photoelectric detection component ensures that components enter the next production stage in the correct order and position, avoiding product quality problems caused by transmission errors or omissions, and improving product pass rate and consistency. The detection data from the photoelectric detection component can be integrated with other production systems to optimize and schedule the production process, such as automatically adjusting the equipment's operating speed or issuing fault alarms based on the entry and exit status of components, improving production flexibility and response speed.

[0023] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a multi-layer roller conveying structure, which has the following beneficial effects:

[0024] 1. Significantly improves transmission efficiency: The multi-layer transmission structure can handle the material output needs of multiple layers of components at the same time. Compared with traditional single-layer transmission equipment, it greatly reduces the output cycle time and significantly improves production efficiency, especially suitable for the high efficiency requirements of large-scale production.

[0025] 2. Avoid material blockage: Each layer of the conveying mechanism is equipped with an independent drive mechanism, which can operate independently. This effectively avoids the problem of component accumulation caused by the inability of a single-layer conveying device to handle multiple layers of components at the same time, ensuring the continuity of production and reducing the risk of production line downtime and maintenance costs caused by material blockage.

[0026] 3. Enhanced equipment adaptability: The equipment can be flexibly adjusted according to the specific number of layers, layer spacing, and discharge conditions of the multi-layer laminator, including the height adjustment of the conveyor frame and the staggered arrangement of the drive mechanism. This high degree of flexibility allows the equipment to adapt to multi-layer laminators of different specifications, reducing the cost and management complexity for enterprises in equipment configuration.

[0027] 4. Improve equipment stability and reliability: By optimizing the structural design (such as stable support of the transmission frame, fine-tuning function of support bolts, and precise transmission of gears and teeth), the equipment is more stable during operation, reducing failures caused by structural instability or transmission errors and extending the service life of the equipment.

[0028] 5. Optimized cooling effect: The cooling fan assembly installed at the bottom of the rack can continuously cool the photovoltaic modules during transmission, effectively preventing the modules from thermal damage, deformation or damage due to high temperature, while shortening the cooling time and further improving production efficiency.

[0029] 6. Intelligent Detection and Monitoring: The photoelectric detection components installed on the rack can monitor the entry and exit status of components in real time, realizing intelligent detection. This real-time monitoring function can promptly detect abnormalities during transmission, avoiding product quality problems caused by transmission errors or omissions, while optimizing the production process and improving the level of automation and management.

[0030] 7. Space utilization and compact structure: The staggered drive mechanism and compact transmission frame design make the equipment more efficient in space utilization, reduce the floor space occupied, and avoid the inconvenience of installation and maintenance caused by excessive equipment size.

[0031] 8. Reduced Energy Consumption and Costs: The high efficiency of gear transmission and the optimized design of the cooling fan assembly improve the energy utilization efficiency of the equipment and reduce energy consumption. At the same time, the flexibility and reliability of the equipment reduce the additional costs associated with equipment adjustment, maintenance, and replacement.

[0032] 9. Improve product quality: Through precise transmission control, cooling optimization and intelligent detection, the equipment can ensure that components are not damaged during transmission and enter the next production stage in the correct order and position, thereby significantly improving the product qualification rate and consistency.
