[0002] As the global demand for renewable energy increases, the photovoltaic industry is developing rapidly. Monocrystalline silicon solar cells have become the mainstream product in the market due to their high efficiency and good performance. In order to meet the growing market demand, it is particularly important to improve production efficiency and automation level. The precision weighting device of the monocrystalline silicon automatic packaging line is one of the important equipment in modern semiconductor manufacturing and photovoltaic industry. It is an important part of ensuring product quality, improving production efficiency, ensuring product consistency, and reducing production costs. This development not only reflects the trend of technological progress, but also shows the industry's pursuit of automation and intelligence.

The capping mechanism 26 includes a base 2601, a fourth servo motor 2602, a driving gear 2603, a driven gear 2604, a mounting seat 2605, a lifting cylinder 2606, a first mounting block 2607, a connecting column 2608, a second mounting block 2609, a mounting plate 2610, and a vacuum suction cup 2611.

[0027] Furthermore, the support platform 2 has two layers, and the support platform 2 is located on the crossbeam of the frame 1.

[0028] Specifically, the support table 2 can be used to temporarily store packaged finished products, which can be used as a transfer transition to help balance the processing rhythm and avoid external factors affecting the entire processing flow. Raw materials can also be stored to reduce the time workers spend on obtaining raw materials, improve production efficiency and reduce processing delays caused by raw material shortages.

[0029] Furthermore, a first servo motor 5 is fixedly installed on the right side of the rear of the first conveyor 3, and the output end of the first servo motor 5 is fixedly connected to the first sprocket 6, and the first sprocket 6 is rotatably connected to the first chain plate 4. A third servo motor 16 is fixedly installed on the left side of the rear of the third conveyor 20, and the output end of the third servo motor 16 is fixedly connected to the third sprocket 18, and the third sprocket 18 is rotatably connected to the third chain plate 17.

[0030] Specifically, the first servo motor 5 and the third servo motor 16 can accurately control the stop position and feed back the signal to the control cabinet 24, and then cooperate with the rapid start and stop of the first servo motor 5 and the third servo motor 16 to indirectly realize the accurate separation of the single crystal silicon raw materials into the same mass. By using the sprocket chain system, which is a rigid transmission method without sliding, it can simplify the mechanical structure, reduce the demand for other transmission elements, and improve the working efficiency of the entire system, thereby reducing the complexity and cost of the overall design.

[0031] Furthermore, a second servo motor 11 is fixedly installed on the left rear portion of the second conveyor 12 , and a second sprocket 15 is fixedly connected to the output end of the second servo motor 11 , and the second sprocket 15 is rotatably connected to the second chain plate 13 , and a plurality of isolation blocks 14 are evenly fixedly installed on the outer side of the second chain plate 13 .

[0032] Specifically, the isolation block 14 can evenly divide the second chain plate 13 into several areas, so that the monocrystalline silicon can be stored separately in an area, and the effective width of the second chain plate 13 can be fully utilized, thereby improving the efficiency of space utilization and effectively preventing materials from overflowing during transportation due to vibration, tilting, etc., thereby reducing waste and pollution, affecting the weight of each portion after the final packaging is completed, and affecting subsequent processing procedures.

[0033] Furthermore, a weighing sensor 9 is fixedly mounted on the top of the mounting frame 10 , a barrel 8 is arranged above the weighing sensor 9 , and a first collecting trough 7 is arranged on the right side of the top of the barrel 8 .

[0034] Specifically, the weighing sensor 9 can detect the quality of the monocrystalline silicon in the barrel 8 in real time, and transmit the signal changes to the control cabinet 24. The control cabinet 24 will feedback the signal to the first servo motor 5 and the second servo motor 11 so that they can quickly make corresponding actions. The weighing sensor 9 can also be used for load to prevent overloading, thereby protecting the safety of equipment and operators. The first collecting trough 7 can gather the monocrystalline silicon raw materials transported on the first chain plate 4 to ensure that the raw materials will not be scattered into the surrounding environment, reducing the safety hazards caused by material sliding or dumping. The model of the weighing sensor 9 is an HBM sensor.

[0035] Furthermore, a partition 27 is provided at the bottom of the barrel 8, and sliders 29 are fixedly installed on both sides of the partition 27. The sliders 29 are slidably connected to a rodless cylinder 28. One end of the rodless cylinder 28 is fixedly installed on the outside of the barrel 8, and the other end of the rodless cylinder 28 is fixedly installed on a cross bar 30. Both ends of the cross bar 30 are fixedly installed on the inner side of the mounting frame 10.

[0036] Specifically, since the rodless cylinder 28 has no exposed piston rod, the overall structure is more compact, and its stroke is not limited by the length of the piston rod, a longer stroke can be achieved, and it can be adjusted as needed, with better flexibility. Due to its simple structure and fewer friction parts, its movement efficiency is higher and its service life is extended. The partition 27 can play a supporting role inside the barrel 8.

[0037] Furthermore, a first photoelectric sensor 21 is installed on the top of the first angle iron 31 , and a second photoelectric sensor 22 is installed on the top of the second angle iron 32 . The second photoelectric sensor 22 is located on the left side of the first photoelectric sensor 21 .

[0038] Specifically, the first angle iron 31 and the second angle iron 32 have good bending and tensile strength, and their L-shaped cross-sectional design is not easy to deform when subjected to external pressure, thereby reducing the risk that the box will hit the first angle iron 31 and the second angle iron 32 due to the difference in the placement position of the box, resulting in changes in the positions of the first photoelectric sensor 21 and the second photoelectric sensor 22, thereby affecting their response results. The first photoelectric sensor 21 and the second photoelectric sensor 22 each have a pair, consisting of an emitter and a receiver. The emitter sends a light beam to the receiver. When an object blocks the light beam, the receiver detects a change in the light signal and determines the presence of the box based on the received light signal, thereby achieving non-contact detection and reducing damage to the box. The detection distances of the first photoelectric sensor 21 and the second photoelectric sensor 22 can be adjusted, with high flexibility. When the box is not detected on the third chain plate 17, the control cabinet 24 cannot obtain a feedback signal, and the second servo motor 11 will not drive the second sprocket 15 to rotate, thereby ensuring the stability of the entire mechanism. The capping mechanism 26 will not move without receiving a feedback signal. The first photoelectric sensor 21 and the second photoelectric sensor 22 are both Panasonic EX-10 series.

[0039] Furthermore, a fourth servo motor 2602 is fixedly installed on the right side of the base 2601, a driving gear 2603 is fixedly installed on the output end of the fourth servo motor 2602, the driving gear 2603 is meshingly connected with a driven gear 2604, a mounting seat 2605 is fixedly connected to the top of the driven gear 2604, a lifting cylinder 2606 is fixedly installed on the top of the mounting seat 2605, a first mounting block 2607 is fixedly installed on the top of the telescopic end of the lifting cylinder 2606, and a second mounting block 2609 is fixedly installed on the front side of the first mounting block 2607 through a connecting column 2608.

[0040] Specifically, the mounting seat 2605 can rotate in the horizontal direction, and through the fourth servo motor 2602, it can realize accurate position change and reduce the error generated when pressing the cover. The engagement of the driving gear 2603 and the driven gear 2604 can realize high-precision motion transmission and ensure the stability of the system. The lifting cylinder 2606 can move the first mounting block 2607 in the vertical direction. The lifting cylinder 2606 uses compressed air as the power source, can respond and execute actions quickly, and quickly reach the required working position. It has a simple structure and high reliability, and is suitable for long-term continuous work and lifting.

[0041] Furthermore, a mounting plate 2610 is fixedly mounted on the bottom of the second mounting block 2609 , and a plurality of vacuum suction cups 2611 are mounted on the bottom of the mounting plate 2610 , and the vacuum suction cups 2611 are arranged at equal distances on the mounting plate 2610 .

[0042] Specifically, the vacuum suction cup 2611 can quickly and effectively grasp the box cover, has a large contact area and evenly distributes pressure, can effectively reduce damage to the surface of the object, reduce the risk of the object falling and being damaged, can accurately grasp the box cover on the workbench 23, reduces manual intervention, reduces labor intensity, and its clamping process is quick and simple, greatly improving packaging efficiency.

[0043] Working principle: First, the support table 2 can be used to temporarily store the packaged finished products, which can be used as a transfer transition to help balance the processing rhythm and avoid the entire processing flow being affected by external factors. It can also be used to store raw materials, which can reduce the time workers spend on taking raw materials, improve production efficiency and reduce processing delays caused by raw material shortages. The first servo motor 5 and the third servo motor 16 can accurately control the stop position and feed the signal back to the control cabinet 24, and then cooperate with the first servo motor 5 and the third servo motor 16 to start and stop quickly, which can indirectly realize the precise separation of the single crystal silicon raw materials into the same quality. By using the sprocket chain plate system, the mechanical structure can be simplified, the demand for other transmission elements can be reduced, and the working efficiency of the entire system can be improved, thereby reducing the overall design. The complexity and cost of the design, secondly, the isolation block 14 can evenly divide the second chain plate 13 into several areas, so that the monocrystalline silicon can be stored in an area alone, which can make full use of the effective width of the second chain plate 13, improve the efficiency of space use, and effectively prevent them from spilling due to vibration, tilt and other reasons during transportation, thereby reducing waste and pollution, affecting the weight of each portion after the final packaging is completed, and affecting subsequent processing procedures. The weighing sensor 9 can detect the quality of the monocrystalline silicon in the barrel 8 in real time, and transmit the signal change to the control cabinet 24. The control cabinet 24 will feedback the signal to the first servo motor 5 and the second servo motor 11 to make it perform corresponding actions. The weighing sensor 9 can also be used for load to prevent overloading. Thereby protecting the safety of the equipment and operators, the first collecting trough 7 can gather the monocrystalline silicon raw materials transported on the first chain plate 4 to ensure that the raw materials will not be scattered into the surrounding environment, reducing the potential safety hazards caused by material sliding or dumping. The rodless cylinder 28 has no exposed piston rod, making the overall structure more compact, and its stroke is not limited by the length of the piston rod, so a longer stroke can be achieved, and it can be adjusted as needed, with better flexibility. Due to its simple structure and fewer friction parts, its movement efficiency is higher and its service life is extended. The first photoelectric sensor 21 and the second photoelectric sensor 22 each have a pair, consisting of an emitter and a receiver. The emitter sends a light beam to the receiver. When an object blocks the light beam, the receiver detects a change in the light signal. The received light signal is used to determine the existence of the box, so as to realize non-contact detection and reduce the damage to the box. The detection distances of the first photoelectric sensor 21 and the second photoelectric sensor 22 can be adjusted, which is highly flexible. When the box is not detected on the third chain plate 17, the control cabinet 24 cannot get the feedback signal, and the second servo motor 11 will not drive the second sprocket 15 to rotate, thereby ensuring the stability of the entire mechanism. The capping mechanism 26 will not move if it does not get the feedback signal, and the mounting seat 2605 can rotate in the horizontal direction. Through the fourth servo motor 2602, the precise position change can be realized, and the error generated during the capping can be reduced. The meshing of the driving gear 2603 and the driven gear 2604 can realize high-precision motion transmission, thereby ensuring the stability of the system.The lifting cylinder 2606 can move the first mounting block 2607 in the vertical direction. The lifting cylinder 2606 uses compressed air as a power source, can respond and execute actions quickly, quickly reach the required working position, has high reliability, and is suitable for long-term continuous work. Its stroke, speed and force can be adjusted by adjusting the air pressure and flow of compressed air to meet the capping operation of different boxes. The vacuum suction cup 2611 can quickly and effectively grab the box cover. The clamping process is quick and simple, which greatly improves the efficiency of packaging. Several groups of vacuum suction cups 2611 provide a large contact area and evenly distribute pressure, which can effectively reduce damage to the surface of objects and reduce the risk of objects falling and being damaged. The box cover on the workbench 23 can be accurately grabbed, reducing manual intervention and labor intensity.
