Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic equipment industry, and in particular relates to a feeder lifting and lateral movement mechanism. Background Art

[0002] Before 2012, the growth of global photovoltaic installed capacity mainly came from European countries (such as Germany and Italy), and the installed capacity of photovoltaic power stations in my country grew slowly; after 2012, China and other Asian countries gradually became the main contributors to the growth of global photovoltaic installed capacity. From 2013 to 2021, the annual compound growth rate of my country's cumulative photovoltaic power generation capacity reached 61.08%. By the end of 2022, the cumulative installed capacity of domestic photovoltaic power generation reached 392.04GW, and the cumulative photovoltaic installed capacity also surpassed hydropower to become the second largest power source in the country.

[0003] At present, in the process of supplying raw materials to single crystal furnaces, it is necessary to manually break the raw material bags and pour them into the barrel, which is inefficient, labor-intensive, and in a bad environment, and can cause occupational diseases (silicosis) to workers. In order to improve the level of factory automation and informatization, reduce labor intensity, and improve work efficiency, it is very necessary to design and develop automatic feeding equipment for repeated feeding, achieve staff reduction, reduce labor intensity, and achieve the construction of a smart factory with fewer people, automation, and informatization.

[0004] Through the above analysis, the problems and defects of the prior art are as follows:

[0005] 1) Low efficiency: The process of manually breaking the raw material bag and pouring it into the barrel is relatively slow and takes a long time to operate, which cannot meet the high efficiency requirements of the production line. Especially in large-scale production, the efficiency problem of manual feeding is more prominent.

[0006] 2) High labor intensity: During the manual feeding process, workers need to undertake heavy physical labor, and long-term operation may cause worker fatigue. In addition, workers also need to work in a harsh environment with high temperature, high humidity and high dust, which greatly increases the labor intensity.

[0007] 3) Harsh environment: The working environment of the raw material supply link of the single crystal furnace usually has adverse factors such as high temperature, high humidity and high dust. Working in such an environment for a long time may cause damage to the health of workers.

[0008] 4) Occupational disease risk: Workers who are exposed to silica dust for a long time are susceptible to silicosis, a chronic occupational disease that seriously affects workers’ quality of life and work ability, and may even lead to death.

[0009] 5) Personnel dependence: Existing technologies are highly dependent on personnel. Once workers are unable to continue working due to illness or other reasons, the normal operation of the production line will be affected.

[0010] 6) Insufficient information level: The existing manual feeding method is difficult to adapt to the information and automated production requirements of modern smart factories, which limits the improvement of factory production efficiency and the expansion of production capacity.

[0011] In order to solve the above problems, it is necessary to design and develop an automatic feeding equipment for multiple feeding to realize the factory's less-manned, automated, and information-based production, improve production efficiency, reduce labor intensity, reduce the risk of occupational diseases, and promote the construction of smart factories. Summary of the invention

[0012] In view of the problems existing in the prior art, the present invention provides a feeder lifting and lateral movement mechanism.

[0013] The present invention is implemented as follows: a feeder lifting and transverse movement mechanism includes: a feeding system transverse movement mechanism, a feeding system lifting mechanism, and an electric vibration feeding system; the feeding system transverse movement mechanism is arranged at the bottom of the mechanism and is rigidly connected to the feeding system lifting mechanism on the top; the electric vibration feeding system is rigidly connected to the feeding system lifting mechanism and is located at the top of the entire mechanism.

[0014] Furthermore, the transverse movement mechanism of the feeding system includes: a base frame and a transverse movement transmission, and the transverse movement transmission is arranged on the upper surface of the base frame.

[0015] Furthermore, the lifting mechanism of the feeding system includes: a lifting frame, a lifting transmission, and a guide rail clamp; the lifting transmission is arranged on the outer surface of the lifting frame, and the guide rail clamp is respectively connected to the lifting frame and the lifting transmission.

[0016] Furthermore, the electric vibration feeding system includes: an electric vibrator, a collecting hopper, and a discharging hopper; the discharging hopper is arranged at the outermost end and connected to the electric vibrator, and the electric vibrator is arranged in the middle and connected to the collecting hopper.

[0017] Furthermore, the lateral transmission is horizontally guided by meshing the gear and rack of the linear guide.

[0018] Furthermore, the lifting transmission uses a servo electric cylinder to provide the lifting power, and vertical guidance is performed through the meshing of the gear and rack of the linear guide.

[0019] Furthermore, the electric vibrator transports the silicon material uniformly by means of vibration.

[0020] Furthermore, the discharging hopper can adjust its own inclination angle according to the different angles of the barrel.

[0021] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0022] First, the present invention solves the problems in the raw material supply link of the current photovoltaic industry. At present, it still relies on manual opening of raw material bags and pouring them into the feed cylinder, which has the defects of low efficiency, high labor intensity, harsh environment, and the risk of occupational diseases such as silicosis for workers, and high labor costs. In order to improve the automation and informatization level of the factory, reduce labor intensity, and improve work efficiency, so as to achieve personnel reduction, reduce labor costs, improve product competitiveness, and reduce labor intensity, and complete the construction of a smart factory with less manpower, automation, and informatization.

[0023] Second, the function of the traversing mechanism of the feeding system is that the entire lifting and traversing mechanism of the feeder is installed above the chassis, used to bear the weight of the entire equipment. The gear meshes with the rack, and the linear guide plays a guiding role, enabling the entire system to accurately traverse left and right to cooperate with different angles of the feed cylinder to complete the feeding process.

[0024] The function of the lifting mechanism of the feeding system is that the lifting frame holds the feeding system for up and down movement. The servo electric cylinder provides the power for lifting, and the linear guide plays a guiding role. The guide rail clamp plays an anti-falling role when the lifting is in place, enabling the entire system to accurately lift up and down to cooperate with different angles of the feed cylinder to complete the feeding process.

[0025] The function of the electric vibration feeding system is to pour the silicon material of one formula into the aggregate hopper above the electric vibrator. The electric vibrator evenly vibrates and conveys the silicon material to the discharge hopper. The discharge hopper can adjust its own inclination angle according to different angles of the feed cylinder to prevent material scattering during the filling process.

[0026] Third, as the creative auxiliary evidence of the claims of the present invention, it is also reflected in the following important aspects:

[0027] (1) The expected benefits and commercial value after the transformation of the technical solution of the present invention are as follows: After the transformation of the technical solution of the present invention, a large amount of labor costs will be reduced, and the competitiveness of Chinese photovoltaic products in the international market will be improved. In 2022, the output of photovoltaic monocrystalline silicon in China reached 357 GW. Calculated based on reducing 4 people per 5 GW per shift, a total of about 856 workers can be reduced, reducing the labor costs of photovoltaic enterprises and the labor shortage in this process (due to silicosis).

[0028] (2) Whether the technical solution of the present invention solves the technical problems that people have always been eager to solve but have never been successful in solving: The technical solution of the present invention adopts a brand-new design concept - the silicon material feeding trolley only performs swinging actions, and the feeding system performs lifting and traversing actions. The two cooperate to complete the silicon material feeding process. Compared with the existing equipment (the silicon material feeding trolley performs swinging, lifting, and traversing actions), it reduces the space occupied by the equipment, especially the height of the equipment (1 meter lower than the original equipment), reduces the renovation cost of old factories, and is especially friendly to some old factories that cannot be renovated.

[0037] The lifting mechanism 2 of the feeding system includes: a lifting frame 201, a lifting drive 202, and a guide rail clamp 203; the lifting drive 202 is arranged on the outer surface of the lifting frame 201, and the guide rail clamp 203 is respectively connected to the lifting frame 201 and the lifting drive 202.

[0038] The electric vibration feeding system 3 includes: an electric vibrator 301, an aggregate hopper 302, and a discharge hopper 303; the discharge hopper 303 is arranged at the outermost end and connected to the electric vibrator 301, and the electric vibrator 301 is arranged in the middle part and connected to the aggregate hopper 302.

[0039] Structural principle of the feeder lifting and traversing mechanism provided by the embodiment of the present invention:

[0040] The feeder lifting and traversing mechanism includes a traversing mechanism 1 of the feeding system, a lifting mechanism 2 of the feeding system, and an electric vibrating feeding system 3.

[0041] The traversing mechanism 1 of the feeding system is composed of two parts. The first is the chassis 101 that bears the weight of all equipment, and the second is the traversing drive 102 that provides traversing power and is composed of a precision gear and rack and a linear guide drive mechanism.

[0042] The lifting mechanism 2 of the feeding system is composed of three parts. The first is the lifting frame 201 that supports the lifting of the feeding system, the second is the lifting drive 202 that provides lifting power and is composed of a servo electric cylinder and a linear guide drive mechanism, and the third is the guide rail clamp 203 for anti-falling when lifting in place.

[0043] The electric vibrating feeding system 3 is composed of three parts. The first is the electric vibrator 301 that evenly vibrates and conveys the silicon material into the discharge hopper for filling, the second is the aggregate hopper 302 that stores the formulated silicon material, and the third is the discharge hopper 303 that connects and pours the silicon material conveyed by the electric vibrator into the barrel.

[0044] The function of the traversing mechanism 1 of the feeding system is that the entire feeder lifting and traversing mechanism 1 is installed above the chassis 101 to bear the weight of the entire equipment. The gear meshes with the rack, and the linear guide plays a guiding role, enabling the entire system to accurately traverse left and right to cooperate with different angles of the barrel to complete the feeding process and achieve automatic feeding for repeated feeding.

[0045] The function of the lifting mechanism 2 of the feeding system is that the lifting frame 201 supports the feeding system for up and down lifting movement. The servo electric cylinder provides the power for lifting, the linear guide plays a guiding role, and the guide rail clamp 203 plays an anti-falling role when lifting in place, enabling the entire system to accurately lift up and down to cooperate with different angles of the barrel to complete the feeding process and achieve automatic feeding for repeated feeding.

[0046] The function of the electric vibrating feeding system 3 is to pour a formulated silicon material into the aggregate hopper 302 above the electric vibrator 301. The electric vibrator 301 evenly vibrates and conveys the silicon material into the discharge hopper 303. The discharge hopper 303 can adjust its own inclination angle according to different angles of the barrel to prevent material scattering during the filling process.

[0047] Key points of the feeder lifting and traversing mechanism provided by the embodiment of the present invention:

[0048] The entire feeder lifting and traversing mechanism is installed above the chassis 101. The gear engages with the rack, and the linear guide plays a guiding role, enabling the entire system to accurately traverse left and right to cooperate with different angles of the barrel to complete the feeding process. The lifting frame 201 supports the feeding system for lifting and moving. The servo electric cylinder provides the power for lifting, and the linear guide plays a guiding role, enabling the entire system to accurately lift up and down to cooperate with different angles of the barrel to complete the feeding process. The silicon material of one formula is poured into the aggregate hopper 302 above the electric vibrator 301. The electric vibrator 301 evenly vibrates and conveys the silicon material into the discharge hopper 303. The discharge hopper 303 can adjust its own inclination angle according to different angles of the barrel to prevent material scattering during the filling process.

[0049] The structural functions of each part of the feeder lifting and traversing mechanism provided by the embodiment of the present invention are as follows:

[0050] The traversing mechanism 1 of the feeding system includes: the chassis 101, the traversing transmission 102.

[0051] The chassis 101: The entire equipment is installed above it, bearing the weight of the entire equipment;

[0052] The traversing transmission 102: The gear engages with the rack, and the linear guide plays a guiding role;

[0053] The lifting mechanism 2 of the feeding system includes: the lifting frame 201, the lifting transmission 202, the guide rail clamp 203.

[0054] The lifting frame 201: Supports the feeding system for lifting and moving;

[0055] The lifting transmission 202: The servo electric cylinder provides the power for lifting, and the linear guide plays a guiding role;

[0056] The guide rail clamp 203: Prevents falling when the lifting is in place.

[0057] The feeding system 3 includes: the electric vibrator 301, the aggregate hopper 302, the discharge hopper 303.

[0058] The electric vibrator 301: Responsible for evenly vibrating and conveying the silicon material;

[0059] The aggregate hopper 302: Responsible for storing the silicon material of the formula;

[0060] The discharge hopper 303: Responsible for connecting the silicon material sent out by the vibrator into the barrel.

[0061] The technical solution of the present invention adopts a brand-new design concept - the silicon material feeding trolley only performs a swinging action, and the feeding system performs lifting and horizontal movement actions. The two cooperate to complete the silicon material feeding process. Compared with the existing equipment (the silicon material feeding trolley performs swinging, lifting, and horizontal movement actions), the structure of the equipment is greatly simplified, the cost of the equipment is reduced (the equipment cost is reduced by 20%), the space occupied by the equipment, especially the height of the equipment (is reduced by 1 meter compared with the original equipment), the renovation cost of the old factory building is reduced, which is especially friendly to some old factory buildings that cannot be renovated.

[0062] Since the technical solution of the present invention has a relatively large load-bearing (the lifting load is 500KG) and a relatively high lifting and horizontal movement accuracy (±0.1mm), we have extensively used the finite element analysis of Solidworks to ensure that our equipment can meet the design requirements. Below, we will take the fixed plate of the lifting electric cylinder as an example to show the finite element analysis. As Figure 4 From our finite element analysis, the deformation amount at the fixed position of the lifting electric cylinder reaches 0.28mm, which does not meet the design requirements. We have strengthened the design of the plate, and the deformation amount meets the design requirement of not exceeding 0.05mm.

[0063] The detailed working principle of the feeding device lifting and horizontal movement mechanism provided by the embodiment of the present invention:

[0064] The horizontal movement mechanism 1 of the feeding system bears the weight of the entire equipment through the chassis 101. The horizontal movement drive 102 adopts the method of meshing gears with racks and linear guides to achieve the smooth movement of the equipment in the horizontal direction. When feeding different barrels is required, the horizontal movement mechanism 1 performs a translation operation on the equipment according to the control signal to align with the target barrel.

[0065] The lifting mechanism 2 of the feeding system holds the feeding system through the lifting frame 201 for lifting movement. The lifting drive 202 uses a servo electric cylinder to provide lifting power and realizes smooth lifting movement with the help of linear guides. The guide rail clamp 203 clamps when the lifting is in place to prevent the equipment from accidentally falling.

[0066] The feeding system 3 is responsible for the conveying and discharging of silicon materials. The electric vibrator 301 evenly conveys the silicon materials to the aggregate hopper 302 through vibration. The aggregate hopper 302 stores the silicon materials stored according to the formula. When feeding is required, the silicon materials are connected from the discharge hopper 303 to the barrel to complete the feeding process.
