Description

Technical Field

[0001] The invention belongs to the technical field of silicon rod processing equipment, and in particular relates to an integrated device for automatic cutting, cleaning and drying of silicon rods. Background Art

[0002] At present, the cutting and cleaning of silicon rods in the photovoltaic industry mainly rely on manual handling and manual cleaning. Some semi-automatic logistics lines only use belt conveyors to transport them to the cutting station for cutting, and then manually transport them to the conveyor belt, and then send them to the cleaning station by the conveyor belt. Finally, workers manually complete the handling and cleaning work. This working method has the following problems:

[0003] ①High labor intensity. This production method cannot integrate cutting, transportation and cleaning. Workers need to carry and clean manually, which is labor-intensive.

[0004] ② High investment cost: This production method requires the purchase of cutting equipment, conveying equipment, and cleaning equipment, and each process requires a large number of workers to complete, with high investment and use costs.

[0005] ③ Large silicon material loss. On the one hand, conventional silicon rod cutting equipment requires manual line drawing and manual placement, resulting in large cutting errors, high re-cutting rate, and large silicon material loss; on the other hand, conventional belt conveyors are used to transport silicon rods, which are prone to collisions, resulting in silicon rod loss; thirdly, manual transport of silicon rods back and forth between belt conveyors and equipment is also prone to operational errors, resulting in silicon rod loss.

[0006] ④ Large floor space. This production solution cannot integrate cutting and cleaning work, so a large number of cutting and cleaning equipment need to be installed, occupying a large amount of production space. Summary of the invention

[0007] In view of the various deficiencies of the prior art and in order to solve the above problems, an integrated device for automatic cutting, cleaning and drying of silicon rods is proposed, which integrates the silicon rod cutting, cleaning and drying operations to improve work efficiency.

[0017] Furthermore, the cleaning conveying assembly includes conveying belt conveyors on both sides and a middle transition belt conveyor, and the middle transition belt conveyor is located between the conveying belt conveyors on both sides and the lifting conveying assembly.

[0018] Furthermore, the conveying belt conveyors on both sides and the middle transition belt conveyor are synchronously driven by a second driving motor.

Therefore, the directional words used are used to illustrate rather than limit the invention.

[0035] Embodiment 1:

[0036] like Figure 1 As shown, an integrated device for automatic cutting, cleaning and drying of silicon rods comprises a cutting mechanism 1, a cleaning mechanism 2, a drying mechanism 3, a straightening mechanism 4 and a conveying mechanism 5 in sequence. The cutting mechanism 1 is used to cut the silicon rods in sections, the cleaning mechanism 2 is used to clean the cut silicon rods, the drying mechanism 3 is used to dry the cleaned silicon rods, the straightening mechanism 4 is used to straighten the dried and tilted silicon rods, and the conveying mechanism 5 is used to convey the silicon rods to the cutting mechanism 1, the cleaning mechanism 2, the drying mechanism 3 and the straightening mechanism 4 in sequence. In other words, the various mechanisms work together to complete the cutting, cleaning and drying of the silicon rods.

[0037] like Figure 1-Figure 3 As shown, the conveying mechanism 5 sequentially includes a lifting conveying assembly 6, a cleaning conveying assembly 7, a blow-drying conveying assembly 8 and a straightening conveying assembly 9 in a linear structure, and sequentially conveys the silicon rods to the cutting mechanism 1, the cleaning mechanism 2, the blow-drying mechanism 3 and the straightening mechanism 4. The cleaning conveying assembly 7 has the same structure as the blow-drying conveying assembly 8, and the lifting conveying assembly 6 has the same structure as the straightening conveying assembly 9.

[0038] A lifting electric cylinder 10 is provided below the lifting and conveying assembly 6. The lifting and conveying assembly 6 is arranged in the horizontal direction, and the lifting electric cylinder 10 is arranged in the vertical direction, and the telescopic end of the lifting electric cylinder 10 is connected to the lifting and conveying assembly 6. In other words, the lifting and conveying assembly 6 can be lifted and lowered as a whole in the vertical direction to convey the silicon rods to the cutting mechanism 1 and convey the silicon rods cut by the cutting mechanism 1 to the next process. Specifically, the lifting and conveying assembly 6 includes a first driving motor, a first driving wheel, a first driven wheel, a first supporting idler wheel and a first synchronous belt. The output end of the first driving motor is connected to the first driving wheel, and the first synchronous belt passes around the first driving wheel, the first supporting idler wheel and the first driven wheel in sequence. Start the first driving motor to drive the first synchronous belt to rotate to convey the silicon rods.

[0039] The cleaning conveying assembly 7 includes conveying belts 11 on both sides and a middle transition belt 12, and the middle transition belt 12 is located between the conveying belts 11 on both sides and the lifting conveying assembly 6. Specifically, the conveying belts 11 on both sides include a second driving motor 13, a second driving wheel 28, a second driven wheel, a second supporting idler wheel and a second synchronous belt, the output end of the second driving motor 13 is connected to the second driving wheel 28, and the second synchronous belt passes around the second driving wheel 28, the second supporting idler wheel and the second driven wheel in sequence. The middle transition belt 12 includes a transition driving wheel 29, a transition driven wheel 30 and a transition belt 31, and the transition driving wheel 29 and the second driving wheel 28 are arranged on the same wheel axis, that is, the conveying belts 11 on both sides and the middle transition belt 12 are synchronously driven by the second driving motor 13. At the same time, the transition driven wheel 30 is located on the same straight line as the first driven wheel to achieve the transition function.

[0040] The transition driven wheel 30 is provided with a transition seat 32 and a tensioning bolt 33, and the transition seat 32 is connected to the transition driven wheel 30 through the tensioning bolt 33. By tightening the tensioning bolt 33, the transition belt 31 is tensioned. The first synchronous belt, the second synchronous belt, and the transition belt 31 are symmetrically and spaced apart. The spacing between the two transition belts 31 is smaller than the spacing between the two second synchronous belts.

[0041] like Figure 1 and Figure 4 As shown, the cleaning mechanism 2 includes a cleaning shield 14 and a cleaning pipe 15. The cleaning shield 14 is arranged across the cleaning conveying assembly 7. At the same time, the cleaning conveying assembly 7 and the cleaning shield 14 are both located above the first mounting seat 17. The cleaning pipe 15 is located in the cleaning shield 14 and is connected to an external water source. Nozzles 16 are evenly distributed on the cleaning pipe 15. The cleaning pipe 15 and the nozzles 16 form a continuous long cubic cleaning space. The silicon rod passes through the cleaning space, which can achieve all-round overall cleaning. The cleaning wastewater is collected by the first mounting seat 17. In addition, the first mounting seat 17 and the cleaning shield 14 form a closed cleaning space to prevent wastewater from splashing outward during cleaning.

[0042] like Figure 1 and Figure 5As shown, the drying mechanism 3 includes a drying shield 18 and an air knife group 19. The drying shield 18 is arranged across the drying conveying assembly 8. At the same time, the drying shield 18 and the drying conveying assembly 8 are both located above the second mounting seat 20. The air knife group 19 is connected to the high-pressure air source through a pipeline, and the air knife groups 19 are respectively arranged on the side walls and the top surface of the drying shield 18. There are multiple air knife groups 19 to form a multi-channel square air curtain group. The silicon rod passes through the square air curtain group to achieve all-round overall drying. The waste water formed by drying is collected by the second mounting seat 20. In addition, the second mounting seat 20 and the drying shield 18 form a closed drying space to prevent waste water from splashing outward during drying.

[0043] like Figure 1 , Figure 6 and Figure 7 As shown, the straightening mechanism 4 includes a detection component 21, a straightening rod 23 and a guide rod cylinder 22. The detection component 21 is used to detect whether the silicon rod has fallen. The guide rod cylinder 22 is located below the straightening conveying component 9 and is tilted. One end of the straightening rod 23 is connected to the telescopic end of the guide rod cylinder 22, and the other end thereof is rotatably connected to the straightening wheel 24. Specifically, the detection component 21 includes a sensor 25 and a contact rod 26. A mounting plate 27 is connected to the frame of the straightening conveying component 9, and the sensor 25 and the contact rod 26 are respectively located on both sides of the mounting plate 27. The contact rod 26 is arranged in the horizontal direction, and a reset spring is provided on its outer periphery. One end of the contact rod 26 is located on the outer side of the mounting plate 27, and the other end thereof corresponds to the sensor 25, which is used to trigger the sensor. That is, after the contact rod 26 touches the silicon rod, the sensor 25 is triggered; after the silicon rod leaves the contact rod 26, the reset spring returns the contact rod 26 to its original position.

[0044] There are two detection components 21, and the two detection components 21 are respectively located at the top and bottom of the mounting plate 27. When both sensors 25 sense, it means that the silicon rod has not fallen. When the sensor 25 located above has no sense, it means that the silicon rod has fallen. When both sensors 25 have no sense, it means that the silicon rod has not been delivered to the right place. When the sensor 25 detects that the silicon rod has fallen, the guide rod cylinder 22 pushes the straightening rod 23 to extend. At the same time, the straightening conveying component 9 moves in the reverse direction for a certain distance. After the silicon rod is straightened, the straightening conveying component 9 moves forward for a certain distance. The above operation is repeated until both sensors 25 detect the silicon rod and the straightening action is completed.

[0045] During operation, the silicon rod is placed on the lifting and conveying assembly 6. The lifting and conveying assembly 6 sends the silicon rod to the cutting position for cutting according to the input cutting data and under the action of the lifting electric cylinder 10. After the cutting is completed, the lifting and conveying assembly 6 conveys the silicon rod to the middle transition belt conveyor of the cleaning and conveying assembly 7, supports the middle position of the bottom of the silicon rod, and ensures that the cleaning equipment can clean the two sides of the bottom of the silicon rod. Then, the silicon rod is conveyed to the conveying belt conveyors on both sides of the cleaning and conveying assembly 7, supports the positions on both sides of the bottom of the silicon rod, and ensures that the cleaning equipment can clean the middle of the bottom of the silicon rod. Finally, the silicon rod passes through the middle transition belt conveyor and the conveying belt conveyors on both sides of the drying and conveying assembly 8 in turn, and the drying operation on both sides and the middle of the bottom of the silicon rod is completed in turn. When the sensor 25 detects that the silicon rod after drying has fallen, the guide rod cylinder 22 pushes the straightening rod 23 out to straighten the silicon rod.

[0046] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
