Description

Technical Field

[0001] This utility model relates to the field of silicon core sorting technology, and in particular to a silicon core sorting and detection device. Background Technology

[0002] In the field of solar photovoltaic technology, the use of wafer silicon core technology is increasingly adopted in the manufacture of polycrystalline silicon using the modified Siemens process. Since wafer silicon cores need to be sorted, the traditional method involves manually measuring the length of each core using conventional tools (such as calipers), visually judging for breaks or defects, and then manually sorting them into corresponding bins according to preset size standards. The main problems with this method are: firstly, efficiency bottlenecks, as manual measurement and sorting speeds are far slower than automated equipment, making it difficult to meet the needs of large-scale production; secondly, questionable accuracy and reliability, as visual fatigue or lighting conditions can easily cause micro-cracks or internal defects to be missed, leading to potential quality problems flowing into subsequent stages; thirdly, high labor costs and management complexity, as repetitive work requires a large workforce and faces turnover risks, and manual sorting is prone to size misjudgments, requiring additional verification, indirectly increasing costs; and fourthly, lack of data traceability, as manual recording is prone to errors and difficult to create digital archives, hindering quality traceability and process optimization.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment of the present invention provides a silicon core sorting and testing device, including: a testing component 1, a straightening component 2, a buffer platform 3, an alignment component 4, a mounting frame 5, a gripping component 6, and a controller 7. The testing component 1 is mounted above the conveying device. The straightening component 2 is located at one end of the outlet of the testing component 1. The buffer platform 3 is located at one end of the outlet of the straightening component 2, and a placement groove 31 for placing silicon cores is provided on the top of the buffer platform 3. The alignment component 4 is mounted on one side of the buffer platform 3. The mounting frame 5 is mounted on the truss of the production area and can be moved to the top of the buffer platform 3. The gripping component 6 is mounted on the mounting frame 5. The controller 7 is electrically connected to the testing component 1, the straightening component 2, the alignment component 4, the mounting frame 5, and the gripping component 6.

[0028] In use, the silicon core is conveyed to the area below the detection component 1 via a conveying device. The detection component 1 detects the passing silicon core and feeds back the detection information to the controller 7, which records the information. The conveying device then transports the silicon core to the straightening component 2, which flips the silicon cores to the other side according to the specified quantity. The controller 7 then controls the mounting frame 5 to move. Once the mounting frame 5 is in position, the controller 7 controls the gripping component 6 to grip the silicon core on the straightening component 2. The gripped silicon core is placed on the buffer platform 3 and then aligned by the alignment component 4 located on the buffer platform 3.

[0029] In one embodiment, such as Figure 1 As shown, the detection assembly 1 of the detection station includes a gantry mounting frame 11 and an industrial camera 12. The gantry mounting frame 11 is mounted on the frame of the conveyor. The industrial camera 12 is mounted on the gantry mounting frame 11 and faces the conveyor after installation. The controller 7 is electrically connected to the industrial camera 12.

[0030] During use, the conveyor transports the silicon core to the gantry mounting frame 11, where an industrial camera 12 collects data from the silicon core. The collected data is then fed back to the controller 7. The collected data includes the diameter of the silicon core and whether there are cracks on its surface.

[0031] In one embodiment, such as Figure 1As shown, the sizing assembly 2 includes: a rotary motor 21, a rotating rod 22, sizing elements 23, a buffer element 25, and a pusher 27. The rotary motor 21 is installed at the discharge port of the conveying device. The rotating rod 22 is connected to the output shaft of the rotary motor 21. Multiple sizing elements 23 are installed along the axial direction of the rotating rod 22. The outer wall of the sizing element 23 is provided with an opening groove 24 that matches the silicon core, and the direction of the opening groove 24 is the same as the rotation direction of the rotary motor 21. The buffer element 25 is slidably disposed on the side of the sizing element 23 away from the conveying device, and the top of the buffer element 25 is provided with a placement opening 26 for placing the silicon core. The pusher 27 is installed on the frame of the conveying device, and its movable end is connected to the buffer element 25. The controller 7 is electrically connected to the rotary motor 21 and the pusher 27.

[0032] During the silicon core straightening process, the conveying device transports the inspected silicon core to one side of the straightening assembly 2. The rotating motor 21 rotates, causing the straightening component 23 mounted on the rotating rod 22 to rotate. During rotation, the silicon core, which is engaged in the opening slot 24 of the straightening component 23, is carried to the other side and placed in the placement opening 26 of the buffer component 25. During this movement, the conveying device transports the silicon core into the opening slot 24 of the straightening component 23. After the rotating motor 21 causes the silicon core to flip, gravity places it in the buffer component 25 on the other side. Once the silicon core is in place, the controller 7 controls the movement of the pushing component 27, which moves the buffer component 25 a fixed amount of time, ensuring that the silicon core can be smoothly placed into the placement opening 26 of the buffer component 25 after the next rotation of the rotating motor 21.

[0033] In one embodiment, such as Figure 1 As shown, the top of the buffer platform 3 is provided with multiple placement slots 31. Each placement slot 31 is provided with a tray 32 for placing silicon cores, and the tray 32 is provided with a groove 33 for placing silicon cores.

[0034] To facilitate the storage of silicon cores of different diameters, multiple placement slots 31 are provided on the top of the buffer platform 3. Silicon cores of different diameters can be placed in different placement slots 31.

[0035] In one embodiment, the alignment assembly 4 includes: a lifting cylinder 41, an alignment cylinder 42, a mounting plate 43, and an alignment plate 44. The lifting cylinder 41 is mounted on one side of the bottom of the buffer platform 3. The alignment cylinder 42 is mounted on the movable end of the lifting cylinder 41. The mounting plate 43 is mounted on the movable end of the alignment cylinder 42. The alignment plate 44 is mounted on the mounting plate 43. The lifting cylinder 41 and the alignment cylinder 42 are electrically connected to the controller 7.

[0036] When aligning the silicon core placed in the placement slot 31, the controller 7 first controls the lifting cylinder 41 to adjust its height, and then controls the alignment cylinder 42 to move. During the movement, the alignment cylinder 42 drives the mounting plate 43 and the alignment plate 44 mounted on the mounting plate 43 to move, so that the alignment plate 44 aligns one end of the silicon core.

[0037] In another embodiment, the lifting cylinder 41 is mounted on the movable end of the alignment cylinder 42, and the mounting plate 43 is mounted on the movable end of the lifting cylinder 41.

[0038] In use, the controller 7 first controls the lifting cylinder 41 to work and adjust its height, and then controls the alignment cylinder 42 to move.

[0039] It should be noted that the placement slot 31 is provided with a placement plate 634 for placing silicon cores, and the placement plate 634 is provided with grooves 33 for placing silicon cores. The number of alignment plates 44 mounted on the mounting plate 43 matches the number of grooves 33.

[0040] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mounting frame 5 includes a connector 51, a sliding mechanism 52, and a lifting component 53. One end of the connector 51 is slidably mounted on the truss. The sliding mechanism 52 is mounted on the truss, and its movable end is connected to the connector 51. The lifting component 53 is connected to the connector 51, and its movable end is connected to the gripping assembly 6. The sliding mechanism 52 and the lifting component 53 are electrically connected to the controller 7.

[0041] In use, the controller 7 controls the sliding mechanism 52 to move, which in turn drives the connecting member 51 to move. The connecting member 51 slides on the truss, causing the lifting member 53 mounted on the connecting member 51 to move to the designated position. After it moves into position, the controller 7 controls the lifting member 53 to move, so that the gripping component 6 mounted on the lifting member 53 moves closer to the straightening component 2.

[0042] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the gripping component 6 includes: a fixing plate 61, an adsorption component 62, a fall prevention component 63, and a pushing component 64. The fixing plate 61 is connected to the bottom of the mounting frame 5. The adsorption component 62 is mounted on the end of the fixing plate 61 facing the conveying device. The fall prevention component 63 is slidably mounted on both sides of the fixing plate 61 along its length. The pushing component 64 is mounted on one side of the adsorption component 62. The adsorption component 62, the fall prevention component 63, and the pushing component 64 are electrically connected to the controller 7.

[0043] During silicon core grasping, controller 7 first controls adsorption component 62 to adsorb the silicon core. After adsorption, controller 7 controls lifting rod 642 to retract, and then controller 7 controls anti-fall component 63 to move, positioning it below and in contact with the silicon core. Then, controller 7 controls sliding mechanism 52 to slide connector 51, moving the silicon core to a designated position. Finally, controller 7 controls pushing component 64 to separate the silicon core from adsorption component 62.

[0044] In one embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the adsorption assembly 62 includes: a mounting rod 621, a suction cup 622, and an adsorption pump 623. One end of the mounting rod 621 is mounted on the fixing plate 61, and the number of adsorption rods matches the number of silicon core placement slots 31. The suction cup 622 is mounted on the other end of the mounting rod 621. The adsorption pump 623 is mounted on the mounting rod 621 and is connected to the suction cup 622. The controller 7 is electrically connected to the adsorption pump 623.

[0045] When the suction cup 622 comes into contact with the silicon core, the controller 7 controls the adsorption pump 623 to work. When the adsorption pump 623 is working, it generates a negative pressure to adsorb the silicon core onto the suction cup 622. When the silicon core moves to the designated position, the controller 7 controls the lifting rod 642 to descend to the designated position, and then the adsorption pump 623 stops working. However, there is still a certain negative pressure between the suction cup 622 and the silicon core. Therefore, when the adsorption pump 623 stops working, the controller 7 controls the pushing component 64 to move. The pushing component 64 pushes the silicon core adsorbed on the suction cup 622 to the designated position.

[0046] In one embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the fall arrestor 63 includes: a slide rail 631, a sliding drive component 632, a lifting component 633, and a placement plate 634. The slide rail 631 is mounted on both sides of the fixed plate 61. The sliding drive component 632 is mounted on the fixed plate 61. The lifting component 633 is slidably mounted on the slide rail 631, and the movable end of the sliding drive component 632 is connected to the lifting component 633. When the lifting component 633 is installed, its movable end is vertically downward. The placement plate 634 is mounted on the movable end of the lifting component 633, and the side of the placement plate 634 facing the fixed plate 61 has a fall arrestor groove 635 that matches the silicon core.

[0047] In use, the controller 7 controls the sliding drive component 632 to move, causing the lifting assembly 633 to move on the slide rail 631, which in turn moves the placement plate 634 toward both sides of the fixed plate 61. Then, the controller 7 controls the lifting assembly 633 to move, causing the placement plate 634 to descend below the bottom of the silicon core. Then, the controller 7 controls the sliding drive component 632 to move, positioning the placement plate 634 below the silicon core. The controller 7 then raises the lifting assembly 633, placing the silicon core into the corresponding anti-fall groove 635.

[0048] In one embodiment, such as Figure 2 and Figure 4 As shown, the feeding assembly 64 includes a connecting plate 641, a lifting rod 642, and a push plate 643. The connecting plate 641 is installed on one side of the adsorption assembly 62. The lifting rod 642 is installed at the bottom of the connecting plate 641, and the controller 7 is electrically connected to the lifting rod 642. The push plate 643 is installed at the other end of the lifting rod 642.

[0049] During use, the negative pressure causes the silicon core to be adsorbed onto the suction cup 622. Then, the controller 7 controls the lifting rod 642 to move. The lifting rod 642 drives the push plate 643 to drop the silicon core adsorbed on the suction cup 622 to the designated position.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
