DETAILED DESCRIPTION

[0029] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Specific embodiment 1: an automatic feeding device, the main features include a material box elevator 1 and a material box 2. The material box 2 is a square cover plate, and a trapezoidal groove is dug in the middle of the four edges. The material box elevator 1 is a square frame, and a material box conveying mechanism is arranged in the middle, and a lifting mechanism 12 is arranged on one side. The lifting mechanism 12 is provided with a lifting plate 17 below the belt conveyor 3, and a tank chain support 18 is arranged on one side of the lifting plate 17. The bridge type drag chain 19 is fixed with the tank chain support 18 and connected with the frame of the material box elevator 1. The lifting mechanism 12 is provided with a lifting motor 11 on the side opposite to the tank chain support 18, and a sensor 10 is arranged near the frame of the lifting motor 11, and the sensor 10 is connected with the frame through a sensor sheet metal 9. The lifting mechanism 12 is provided with a square outlet between the tank chain support 18 and the lifting motor 11, and a belt passes through the upper and lower of the outlet, the belt is installed on a synchronous wheel, and the lower side is connected with the lifting motor 11. The synchronous wheel is fixed on the support plate 21 through the lifting driving side plate 22, and the support plate 21 is installed on the bottom plate 20, and the bottom plate 20 is connected with the outer frame of the material box elevator 1. The material box 2 is placed on the belt conveyor 3, and a conveying motor is arranged in the middle of the belt conveyor 3, and the conveying motor is connected with a pair of small synchronous wheels, and the small synchronous wheels are sleeved on the driving shaft 8, and the driving shaft 8 penetrates the synchronous wheel and the driving side plate 7. A workpiece sensor 15 is arranged on the belt conveyor 3, and the workpiece sensor 15 is arranged on the sensing support 16, and the sensing support 16 is connected with the belt conveyor 3. In addition, the belt conveyor 3 is provided with a driven side plate 13 on both sides, and the driven side plate 13 is provided with a synchronous wheel in the middle, and a guardrail 4 is further arranged on both sides, and the guardrail 4 is fixed on the belt conveyor 3 through the movable sheet metal 5. A gas buffer stopper 23 is arranged on one side of the middle of the belt conveyor 3, and the stopper is installed on the stop support 14, and the stop support 14 is connected with the belt conveyor 3 through the connecting piece. A plurality of material boxes 2 can be placed on each belt conveyor 3.

[0031] The continuous feeding process can be realized by placing multiple boxes 2 on the belt conveyor 3, which avoids the downtime waiting time caused by the lack of boxes. For example, in a large-scale solar cell production line, if a single box is used for feeding, once the cells in the box are used up, the machine needs to be stopped for manual replacement of the box, which will cause a significant decrease in production efficiency. By placing multiple boxes on the belt conveyor 3, it can ensure that the next box can be replenished in time after the previous box is used up, thereby ensuring the continuous operation of the production line, significantly improving the production efficiency, and meeting the production needs of high-capacity factories.

[0032] The introduction of the automatic feeding device can effectively reduce the manual handling and pouring of materials. In the traditional feeding method, a large number of manual labor is required to transport the cells from the unloading box to the feeding box, and then the feeding and re-inspection sorting are carried out. This not only increases the labor cost, but also may cause errors and accidents due to improper manual operation. For example, during the manual handling process, problems such as cell damage and mixing may occur, affecting the quality of the product. After using the automatic feeding device, the box can be automatically lifted, conveyed and sensed without the need for manual intervention in the feeding process, thereby reducing the dependence on manual labor, reducing labor costs, and improving the safety and stability of production.

[0033] The workpiece sensor 15 provided on the belt conveyor 3 can monitor the state of the materials in the box in real time, such as detecting the number and position of the cells in the box. When the number of cells in the box is insufficient or abnormal, the workpiece sensor 15 can send a signal in time to remind the system to take appropriate action. This helps to avoid product quality problems caused by mixed materials or errors, such as preventing different specifications or grades of cells from being mixed together for re-inspection and sorting, thereby improving the accuracy of material management and the consistency of product quality.

[0034] The introduction of the automatic feeding device can realize the automation and intelligentization of the production line, and improve the automation level of the production line. The automatic feeding device and other equipment on the production line, such as offline testing machines and sorting machines, can realize seamless connection and collaborative work, forming a complete automated production system. For example, when the automatic feeding device transfers the cells in the box to the offline testing machine, the testing machine can automatically perform EL re-judgment, appearance re-judgment and other operations, and feed the test results back to the feeding device for subsequent sorting and processing. This automated production system not only improves production efficiency and product quality, but also reduces manual intervention and errors, improves production stability and reliability. At the same time, it lays a foundation for the construction of a modern intelligent factory for enterprises, enhances the competitiveness and market position of enterprises, and helps enterprises to occupy a favorable position in the fierce market competition.

[0035] The two sides of the belt conveyor 3 are provided with driven side plates 13, which hold the synchronous wheels in the middle. This design can significantly improve the stability of the conveyor. During the conveying process, the synchronous wheels work with the driving wheels of the belt conveyor 3 to ensure that the conveyor belt always moves in synchronization. This synchronization mechanism can effectively prevent the conveyor belt from slipping or deviating during operation. For the conveying of precision components such as solar cell pieces, stability is crucial. Because the position of these components may deviate or be damaged during the conveying process, it will directly affect the smooth progress of subsequent re-measurement and sorting processes. For example, during EL re-determination or appearance re-determination, the position of the cell piece must be accurate to ensure the accuracy of the test results. Therefore, through the design of the driven side plates 13 and synchronous wheels, the cell piece can always remain stable during the conveying process, thereby improving the reliability and product quality of the entire production process.

[0036] The two sides of the belt conveyor 3 are also provided with guardrails 4, which are fixed on the belt conveyor 3 through movable sheet metal 5. This design can enhance the durability of the equipment. During the conveying process, the materials such as cell pieces may be impacted by external forces or their own gravity on the side of the conveyor. The driven side plates 13 and guardrails 4 can withstand these impact forces, reducing damage to the internal structure of the conveyor. For example, if the materials collide or fall during the conveying process, the guardrails 4 can act as a buffer and protection, preventing the side plates or internal mechanical components of the conveyor from being damaged. In addition, the fixing method of the movable sheet metal 5 also facilitates the disassembly and replacement of the guardrails 4, facilitating the maintenance and repair of the equipment. This can repair or replace damaged parts in a timely manner, prolong the service life of the equipment, improve the reliability and stability of the equipment, reduce the maintenance cost of the equipment, and ensure the continuity and stability of the production process.

[0037] The setting of the guardrails 4 can also effectively improve the safety of the equipment. During the production process, materials may accidentally fall during the conveying process, and without the protection of the guardrails 4, the falling materials may injure the operators or damage other equipment. For example, on a large-scale cell piece production line, if the materials fall, they may injure the workers or damage other precision equipment, causing serious safety accidents or production interruptions. The guardrails 4 can block the falling materials and limit them within the conveying area, ensuring the safety of the operators and the surrounding environment. In addition, the fixing method of the movable sheet metal 5 also allows the guardrails 4 to be adjusted according to actual needs to adapt to materials of different heights or shapes.

[0038] The design of the belt conveyor 3 can also optimize the space layout. The design of the driven side plate 13 and the guardrail 4 makes the structure of the belt conveyor 3 more compact, which can better adapt to different production space layouts. In some factory environments with limited space, traditional open conveyors may be difficult to install or occupy too much space, while this design can effectively reduce the floor area of the belt conveyor 3 and improve the space utilization. For example, in some small or compact production lines, the limited space can be fully utilized, and the conveyor and other equipment can be reasonably arranged to improve production efficiency and product quality. At the same time, the guardrail 4 can also play a certain isolation role, separating the conveying area from other production areas to avoid mutual interference. For example, when re-measuring and sorting battery pieces, it can prevent other production activities from affecting the conveying process, ensuring the smooth progress of the production process and improving production efficiency and product quality.

[0039] The gas buffer stopper 23 is arranged on one side of the middle of the belt conveyor 3, which can significantly improve the control accuracy of material conveying. In the production process, sometimes the materials on the conveyor belt need to be temporarily blocked or separated for subsequent processing, testing or sorting operations. For example, in the production line of solar cell pieces, different specifications or grades of cell pieces may need to be separated for different re-measuring and sorting processes. The gas buffer stopper 23 can quickly and accurately block the materials through pneumatic control, so that the materials are arranged in the predetermined position and order on the conveyor belt. This precise control capability can ensure the smooth progress of the subsequent process and improve the coordination and efficiency of the entire production process. For example, when performing EL re-judgment or appearance re-judgment, each cell piece can be ensured to be detected at the correct position, thereby improving the accuracy and reliability of detection and ensuring the quality consistency of products.

[0040] The gas buffer stopper 23 can also effectively reduce the damage of material impact to the conveyor belt. When the material falls from a high place to the conveyor belt, it will generate a certain impact force, which may cause wear or damage to the conveyor belt. For example, when the cell piece falls from the feeding device to the conveyor belt, if there is no effective buffer measure, the conveyor belt may be torn or worn due to long-term impact, affecting its service life and performance. The gas buffer stopper 23 can absorb part of the impact energy and reduce the direct impact of the material on the conveyor belt. In this way, the service life of the conveyor belt can be prolonged, the maintenance cost of the equipment can be reduced, the durability and reliability of the equipment can be improved, and the continuity and stability of the production process can be ensured. The blocking bracket 14 is connected with the belt conveyor 3 through the connecting piece, which makes the installation and adjustment of the gas buffer stopper 23 more flexible and convenient. According to different production needs and material characteristics, the position,

[0041] The angle and force of the air cushion damper 23 can be adjusted to adapt to different conveying control requirements. For example, when handling batteries of different weights or shapes, the force of the air cushion damper 23 can be adjusted to ensure the control effect on the materials. In addition, this connection method also facilitates the disassembly and replacement of the blocking bracket 14 and the connecting piece, facilitating the maintenance and repair of the equipment. For example, when the air cushion damper 23 needs to be replaced or the equipment needs to be upgraded, it can be quickly disassembled and installed, reducing the equipment downtime, improving the maintenance efficiency and flexibility of the equipment, and enhancing the adaptability and reliability of the equipment.

[0042] The arrangement of the air cushion damper 23 and the blocking bracket 14 can also improve the safety and stability of the belt conveyor 3. During the conveying process, if the materials accidentally fall or splash, the blocking bracket 14 can play a blocking and protection role to prevent the materials from causing harm to the operators or surrounding equipment. For example, on some high-speed or high-density conveying lines, materials may splash out due to various reasons, and if there is no effective blocking measure, it may pose a threat to the safety of workers or damage other equipment. The blocking bracket 14 can effectively block the splashing materials, ensuring the safety of operators and equipment. At the same time, the air cushion damper 23 can effectively control the movement state of the materials, avoid equipment damage or production accidents caused by out-of-control materials, and ensure the safety and stability of the production process, providing a strong guarantee for the safety production of enterprises.

[0043] The workpiece sensor 15 is arranged on the sensing bracket 16, and the sensing bracket 16 is connected with the belt conveyor 3. This design can realize accurate detection of the workpieces on the conveying belt. The workpiece sensor 15 can monitor the position and quantity of the workpieces in real time. When the workpieces reach a specific position, the sensor will send a signal to trigger the subsequent control action. For example, on the production line of solar cell pieces, the workpiece sensor 15 can detect whether the cell piece has reached the position for re-measurement and sorting, so as to control the air cushion damper 23 or other mechanisms to perform corresponding operations. By connecting the sensing bracket 16 with the belt conveyor 3, the relative position between the workpiece sensor 15 and the conveying belt can be stabilized, improving the accuracy and reliability of detection, avoiding misjudgment or missed detection due to position deviation of the sensor, and ensuring the smooth progress of the production process.

[0044]

[0045] ​The belt conveyor is provided with a conveying motor in the middle, and the conveying motor is connected with a pair of small synchronous wheels. This design can effectively drive the movement of the conveyor belt. The conveying motor serves as the power source, and through the connection with the small synchronous wheels, it transmits power to the conveyor belt, making it run at a predetermined speed and direction. The design of the small synchronous wheels can ensure the stability and synchronization of power transmission, avoiding the phenomenon of slipping or uneven speed of the conveyor belt during operation. For example, when conveying battery pieces, it is necessary to ensure that the conveyor belt runs at a constant speed to accurately detect and sort. Through the cooperation of the conveying motor and the small synchronous wheels, the speed of the conveyor belt can be accurately controlled, improving the stability and consistency of the conveying, meeting various requirements in the production process. One side of the small synchronous wheel is sleeved on the driving shaft 8, and the driving shaft 8 penetrates the synchronous wheel and the driving side plate 7. This structure can enhance the stability and carrying capacity of the conveyor. The driving shaft 8, as a key component connecting the small synchronous wheel and the driving side plate 7, can withstand various forces generated during the operation of the conveyor belt, such as tension, friction, etc., ensuring the stability of the overall structure of the conveyor. At the same time, the design of the driving shaft 8 can also improve the carrying capacity of the conveyor, so that it can withstand greater load and adapt to the conveying needs of workpieces of different weights and quantities. For example, on a large-scale battery piece production line, the conveyor needs to carry a large number of battery pieces, and the structure of the driving shaft 8 can ensure the stable operation of the conveyor under high load, avoid production interruption due to structural deformation or damage, and improve production efficiency and equipment reliability.

[0046] The lifting mechanism 12 is provided with a lifting plate 17 below the belt conveyor 3, which can realize the automatic lifting function of the material box. The lifting plate 17 can move up and down according to the production demand and the height of the material box, so as to adjust the relative position of the material box and the belt conveyor 3. For example, during the loading or unloading operation of the material box, the lifting plate 17 can lift the material box to an appropriate height, so that it is consistent with the conveying plane of the belt conveyor 3, facilitating the smooth transfer of the workpieces in the material box to the conveyor belt or from the conveyor belt to the material box. Through this automatic lifting method, the efficiency of loading and unloading can be improved, manual intervention can be reduced, labor intensity can be reduced, and the automation degree of the production process can be improved.

[0047] A tank chain support 18 is arranged on one side of the lifting plate 17, which can effectively protect and manage the connection lines such as cables and air pipes. The tank chain support 18 can neatly fix the connection lines such as cables and air pipes in the tank chain, avoiding their wear, pulling or interference during equipment operation. For example, during the lifting operation of the lifting mechanism 12, the connection lines such as cables and air pipes will move with it. If there is no protection of the tank chain support 18, problems such as cable entanglement and breakage may occur, affecting the normal operation of the equipment. The tank chain support 18 can ensure the stability and safety of the connection lines, prolong their service life, and reduce the failure rate of the equipment.

[0048] The bridge-type open drag chain 19 is fixed with the tank chain support 18 and connected with the frame of the magazine lifting machine 1. This design can realize flexible movement and stable support of the connecting line. The bridge-type open drag chain 19 can freely stretch and shrink with the lifting plate 17, ensuring smooth operation of the connecting line at different heights, avoiding equipment operation obstacles caused by too long or too short connecting line. At the same time, it is connected with the frame of the magazine lifting machine 1, which can provide stable support for the connecting line, so that it can maintain good working condition during equipment operation, improve the reliability and stability of the equipment. For example, during the rapid lifting operation of the magazine, the bridge-type open drag chain 19 can respond in time to ensure that the connecting line will not be damaged due to sudden pulling or pressure, ensuring the normal operation of the equipment and the smooth progress of the production process.

[0049] Firstly, this layout can significantly improve the accuracy of motor control. The sensor 10 can monitor the running state of the lifting motor 11 in real time, including position, speed and direction, etc. By installing the sensor 10 near the frame of the lifting motor 11, the running information of the motor can be more accurately obtained, so as to realize accurate control of the motor. For example, during the lifting operation of the magazine, the sensor 10 can monitor the speed and position of the motor to ensure that the magazine can smoothly and accurately reach the predetermined height. This not only avoids unstable lifting or errors caused by improper motor control, but also improves the running accuracy and reliability of the equipment, ensuring the smooth progress of the production process.

[0050] Secondly, the connection of the sensor sheet metal 9 and the frame can provide stable support and protection for the sensor 10. In industrial automation equipment, the sensor 10 often needs to work in harsh environments such as vibration and impact. The sensor sheet metal 9 can effectively reduce the influence of these external factors on the sensor 10, preventing damage or signal interference of the sensor 10 due to vibration or impact. This stable support not only protects the sensor 10, but also ensures the continuity and accuracy of the motor control signal, reduces the risk of equipment downtime caused by sensor 10 failure, improves the stability of the whole system, and ensures the reliability and stability of the equipment in long-time operation.

[0051] In addition, this design also improves the maintenance efficiency of the equipment. The sensor 10 is connected with the frame through the sensor sheet metal 9, making the installation and maintenance of the sensor 10 more convenient and fast. When the sensor 10 needs to be replaced or repaired, the sensor sheet metal 9 can be quickly disassembled, and the sensor 10 can be directly operated without complex disassembly process. This design simplifies the maintenance process, reduces the maintenance time and workload, improves the maintenance efficiency of the equipment, and reduces the maintenance cost. For example, when the equipment needs emergency repair due to failure, quick replacement of the sensor 10 can greatly shorten the equipment downtime, reduce production loss, and improve production efficiency.

[0052] In summary, the lifting mechanism 12 is provided with a lifting motor 11 on the side opposite to the tank chain support 18, and a sensor 10 is provided near the frame of the lifting motor 11, which is connected to the frame through a sensor sheet metal 9. This design not only improves the accuracy of motor control, enhances the stability and reliability of the system, but also improves the maintenance efficiency of the equipment, providing a strong guarantee for the efficient production of modern intelligent factories.

[0053] The lifting mechanism 12 is provided with a square outlet between the tank chain support 18 and the lifting motor 11. This design provides a spacious passageway for the entry and exit of materials. During the material conveying process, the square outlet ensures that the materials can smoothly enter or exit from the lifting plate 17 of the lifting mechanism 12, avoiding the phenomenon of material blockage or jamming caused by narrow passageway, thereby improving the efficiency of material conveying. For example, in a large-scale battery piece production line, a large number of battery pieces need to be quickly taken out from the box and conveyed to the subsequent processing or detection link. The design of the square outlet can meet the high-efficiency conveying demand, ensuring the smooth progress of the production process. At the same time, this spacious outlet design also helps to reduce the damage of materials during the conveying process, improving the integrity of the materials and providing a good foundation for subsequent processing or detection.

[0054] The upper and lower belts pass through the outlet, the belts are installed on the synchronous wheels, and the lower side is connected to the lifting motor 11. This structure design can ensure the smooth running of the belt. The use of synchronous wheels and belts can effectively prevent the belt from slipping or deviating during the conveying process. For example, when the lifting motor 11 drives the belt to run, the synchronous wheel can smoothly transmit the power of the motor to the belt, so that the belt runs according to the predetermined speed and direction, thereby improving the stability of material conveying. This stable conveying method is crucial for ensuring the positional accuracy and consistency of materials during the conveying process, especially when precise machining or detection is performed, which can ensure that each battery piece can be operated at the correct position, improving the accuracy and reliability of machining or detection, thereby improving the quality and consistency of products.

[0055] The synchronous wheel is fixed on the support plate 21 through the lifting driving side plate 22, the support plate 21 is installed on the bottom plate 20, and the bottom plate 20 is connected with the outer frame of the material box lifting machine 1. The structure design enhances the carrying capacity and durability of the equipment. The synchronous wheel is firmly supported by the lifting driving side plate 22 and can withstand larger loads and impact forces. For example, when lifting a heavy material box, the synchronous wheel and the support plate 21 can jointly bear the weight of the material box, avoiding damage to the equipment due to excessive load. The connection of the support plate 21 and the bottom plate 20, and the connection of the bottom plate 20 and the outer frame of the material box lifting machine 1 form a stable support system, further enhancing the structural strength and durability of the equipment.
