Description

Technical Field

[0001] This invention relates to the field of silicon rod processing technology, and more particularly to an upper top structure, a half-sectioning machine, and a half-sectioning method. Background Technology

[0002] Silicon is widely used in the photovoltaic power generation field. To meet the quality parameters of silicon ingots and the shape and size of the next process, preliminary processing of the silicon ingots is usually required, such as cutting a round silicon ingot into a square silicon ingot. However, current cutting equipment cannot move the cutting line to the clamping area of ​​the silicon ingot to perform a half-sectioning operation, that is, to cut the silicon ingot into two silicon ingot blanks along its length. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an upper structure, a half-sectioning machine and a half-sectioning method, which can realize the half-sectioning operation of silicon rods.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an upper lifting structure, a half-sectioning machine and a half-sectioning method, including a first linear reciprocating device, an upper lifting block and an auxiliary clamping device, wherein the movable end of the first linear reciprocating device moves in the vertical direction, and the upper lifting block is disposed on the movable end of the first linear reciprocating device;

[0005] The upper block has a first supporting surface, and the first supporting surface is symmetrically provided with a first top head and a second top head on both sides of its own center line, and the first top head and the second top head are slidably disposed on the first supporting surface in the vertical direction.

[0006] The auxiliary clamping device is located on the side of the upper block near the first top head, and the auxiliary clamping device has a movable end that moves in the vertical direction.

[0007] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows:

[0008] A splitting machine includes a lower top block, a cutting assembly, and an upper top structure as described above. The lower top block is located directly below the upper top block, and a clamping space is formed between the lower top block and the upper top block. The cutting end of the cutting assembly can move vertically and horizontally into and out of the clamping space.

[0009] A method for half-sectioning based on the half-sectioning machine in the above scheme includes a cutting process and a half-sectioning process;

[0010] The feed process includes step S1: feeding the silicon rod into the clamping space, with the second head of the upper top block abutting against the top surface of the silicon rod, and the movable end of the first top block and / or the auxiliary clamping device abutting against the top surface of the silicon rod, and the top head of the lower top block abutting against the bottom surface of the silicon rod.

[0011] Step S2: If the movable ends of the first top head and the auxiliary clamping device both abut against the top surface of the silicon rod in step S1, the movable end of the auxiliary clamping device separates from the top surface of the silicon rod, and then step S3 is executed.

[0012] If, in step S1, the first pusher abuts against the top surface of the silicon rod, and the movable end of the auxiliary pusher maintains a distance from the top surface of the silicon rod, then step S3 is executed.

[0013] If the first top head maintains a distance from the top surface of the silicon rod in step S1, and the movable end of the auxiliary clamping device abuts against the top surface of the silicon rod, the first top head abuts against the top surface of the silicon rod first, and then the movable end of the auxiliary clamping device is separated from the top surface of the silicon rod, and then step S3 is executed.

[0014] Step S3: The cutting end of the cutting assembly enters from below the movable end of the auxiliary clamping device between the auxiliary clamping device and the first mandrel;

[0015] Step S4: The movable end of the auxiliary clamping device abuts against the top surface of the silicon rod;

[0016] Step S5: The first top head separates from the top surface of the silicon rod;

[0017] Step S6: The cutting end of the cutting assembly enters from below the first top head and between the first and second top heads;

[0018] Step S7: The movable end of the first mandrel and / or auxiliary clamping device abuts against the top surface of the silicon rod;

[0019] The semi-sectioning process includes step S8: the cutting end of the cutting component cuts from the top end of the silicon rod to the bottom end of the silicon rod until the silicon rod is cut into two silicon rod blanks.

[0020] The beneficial effects of the present invention are as follows: the silicon rod is placed between the upper top block and the lower top block to form a clamping space, and the lower top block abuts against the bottom surface of the silicon rod, while the first and second top heads of the upper top block and the movable end of the auxiliary clamping device abut against the top surface of the silicon rod. During the splitting process, the movable end of the auxiliary clamp is separated from the top surface of the silicon rod. At this time, since the first and second mandrels are against the top surface of the silicon rod, the silicon rod will not tilt. Then, the cutting end of the cutting assembly enters from below the movable end of the auxiliary clamp between the auxiliary clamp and the first mandrel. Next, the movable end of the auxiliary clamp rests against the top surface of the silicon rod again, and then the first mandrel is separated from the top surface of the silicon rod. At this time, since the movable end of the auxiliary clamp and the second mandrel are against the top surface of the silicon rod, the silicon rod will not tilt. Then, the cutting end of the cutting assembly enters from below the first mandrel between the first and second mandrels (i.e., enters the clamping space). Finally, the first mandrel rests against the top surface of the silicon rod again, and the cutting end of the cutting assembly cuts from the top to the bottom of the silicon rod until the silicon rod is cut into two silicon rod blanks.

[0040] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0041] Silicon is widely used in the photovoltaic power generation field. To meet the quality parameters of silicon ingots and the shape and size of the next process, preliminary processing of the silicon ingots is usually required, such as cutting a round silicon ingot into a square silicon ingot. However, current cutting equipment cannot move the cutting line to the clamping area of ​​the silicon ingot to perform a half-sectioning operation, that is, to cut the silicon ingot into two silicon ingot blanks along its length.

[0042] Based on this, this application provides an upper structure, a half-sectioning machine, and a half-sectioning method to solve the problem that the cutting equipment cannot move the cutting line to the clamping area of ​​the silicon rod to perform half-sectioning operations on the silicon rod.

[0043] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, the present invention discloses a half-sectioning machine, comprising a lower top block 6, a cutting assembly 7, and an upper top structure. The lower top block 6 is located directly below the upper top block 2, and a clamping space is formed between the lower top block 6 and the upper top block 2. The cutting end of the cutting assembly 7 can move vertically and horizontally into and out of the clamping space. The upper top structure includes a first linear reciprocating device 1, an upper top block 2, and an auxiliary clamping device 3. The movable end of the first linear reciprocating device 1 moves vertically, and the upper top block 2 is disposed on the movable end of the first linear reciprocating device 1. The upper top block 2 has a first holding surface, on which a first top head 21 and a second top head 22 are symmetrically arranged around its center line, and the first top head 21 and the second top head 22 are slidably disposed on the first holding surface vertically. The auxiliary clamping device 3 is located on the side of the upper top block 2 near the first top head 21, and the auxiliary clamping device 3 has a movable end that moves vertically. Preferably, the first linear reciprocating device 1 is a motor-driven linear slide mechanism.

[0044] As can be seen from the above description, the beneficial effects of the present invention are as follows: the first linear reciprocating device 1 controls the auxiliary clamping device 3 and the upper top block 2 to move closer to and further away from the silicon rod 10 placed on the lower top block 6. When it is necessary to halve the silicon rod 10, the auxiliary clamping device 3 is first separated from the top surface of the silicon rod 10 to make room for the cutting end of the cutting assembly 7 to enter between the auxiliary clamping device 3 and the first top head 21 from below the movable end of the auxiliary clamping device 3; since the first top head 21 and the second top head 22 abut against the top surface of the silicon rod 10, when the auxiliary clamping device 3 removes the pressure on the top surface of the silicon rod 10, the silicon rod 10 will be restricted by the first top head 21, thereby preventing the silicon rod 10 from tilting.

[0045] Next, the movable end of the auxiliary clamping device 3 rests against the top surface of the silicon rod 10 again, and then the first head 21 is separated from the top surface of the silicon rod 10 to make room for the cutting end of the cutting assembly 7 to enter from below the first head 21 between the first head 21 and the second head 22 (i.e., enter the clamping space of the half-cutting machine holding the silicon rod 10). Since the movable end of the auxiliary clamping device 3 and the second head 22 are against the top surface of the silicon rod 10, when the pressure of the first head 21 on the top surface of the silicon rod 10 is removed, the silicon rod 10 will be restricted by the movable end of the auxiliary clamping device 3, thereby preventing the silicon rod 10 from tilting.

[0046] Finally, the cutting end of the cutting component 7 cuts from the top end of the silicon rod 10 to the bottom end of the silicon rod 10, thereby obtaining two silicon rod blanks.

[0047] Please refer to Figures 3 to 6 As shown, further, the upper top block 2 is provided with elastic elements 24 respectively connected to the first top head 21 and the second top head 22. The upper top block 2 has a fully compressed state, a partially compressed state, and a non-compressed state. When the upper top block 2 is in the fully compressed state, the first top head 21 and the second top head 22 respectively compress the corresponding connected elastic elements 24 and abut against the top surface of the silicon rod 10. When the upper top block 2 is in the partially compressed state, the first top head 21 does not compress the corresponding connected elastic element 24, and the second top head 22 compresses the corresponding connected elastic element 24 and abuts against the top surface of the silicon rod 10. When the upper top block 2 is in the non-compressed state, neither the first top head 21 nor the second top head 22 compresses the corresponding connected elastic element 24 and separates from the top surface of the silicon rod 10. The elastic element 24 is preferably a spring.

[0048] As described above, when the cutting end of the cutting assembly 7 enters between the auxiliary clamping device 3 and the first mandrel 21, and when the cutting end of the cutting assembly 7 is performing a half-sectioning operation, the upper mandrel 2 is in a fully clamped state to ensure the stability of the silicon rod 10. When the cutting end of the cutting assembly 7 enters between the first mandrel 21 and the second mandrel 22, the upper mandrel 2 is in a semi-clamped state. When it is necessary to place or remove the silicon rod 10 into or from the clamping space of the half-sectioning machine, the upper mandrel 2 is in a non-clamped state.

[0049] In one optional embodiment, the maximum extension of the first mandrel 21 on the upper mandrel 2 is 7 mm, and the maximum extension of the second mandrel 22 on the upper mandrel 2 is 12 mm. When the upper mandrel 2 is in a fully compressed state, the extensions of the first mandrel 21 and the second mandrel 22 on the upper mandrel 2 are equal, and the extensions are 1-2 mm. During the process of the cutting end of the cutting assembly 7 entering between the first top head 21 and the second top head 22, the first linear reciprocating device 1 first moves the upper top block 2 away from the silicon rod 10, so that the first top head 21 reaches its maximum extension of 7mm on the upper top block 2 and abuts against the top surface of the silicon rod 10, and the second top head 22 reaches its extension of 7mm on the upper top block 2 and abuts against the top surface of the silicon rod 10. Then the first linear reciprocating device 1 continues to move the upper top block 2 away from the silicon rod 10 by 3mm-4mm, so that the first top head 21 separates from the top surface of the silicon rod 10, thereby making room for the cutting end of the cutting assembly 7 to pass through.

[0050] In an alternative embodiment, the elastic element 24 provided in the upper top block 2 can be replaced with a cylinder or motor that drives the first top head 21 and the second top head 22 to be arranged in a vertical direction.

[0051] Please refer to Figure 3 , Figure 4 and Figure 7 As shown, further, a third top head 23 is slidably disposed on the first top holding surface in the vertical direction, and the third top head 23 is located on the center line of the first top holding surface. An elastic element 24 connected to the third top head 23 is disposed inside the upper top block 2. When the upper top block 2 is in a fully compressed state, the third top head 23 compresses the corresponding connected elastic element 24 and abuts against the top surface of the silicon rod 10. When the upper top block 2 is in a semi-compressed state, the third top head 23 compresses the corresponding connected elastic element 24 and abuts against the top surface of the silicon rod 10. When the upper top block 2 is in a non-compressed state, the third top head 23 does not compress the corresponding connected elastic element 24 and separates from the top surface of the silicon rod 10. When the upper push block 2 is in a fully compressed state, the extension amount of the third push head 23 on the upper push block 2 is equal to the extension amount of the second push head 22 on the upper push block 2. When the upper push block 2 is in a semi-compressed state, the extension amount of the third push head 23 on the upper push block 2 is equal to the extension amount of the second push head 22 on the upper push block 2. When the upper push block 2 is in a non-compressed state, the extension amount of the third push head 23 on the upper push block 2 is equal to the extension amount of the second push head 22 on the upper push block 2.

[0052] As can be seen from the above description, the addition of a third top head 23 and abutting against the top surface of the silicon rod 10 can further improve the stability of the silicon rod 10 in the fully compressed and semi-compressed states by the upper top block 2.

[0053] Please refer to Figure 3 As shown, further, the third top head 23 is provided with a notch 231 facing the first top head 21 at the end away from the upper top block 2.

[0054] As described above, the first and second abutments 21 and 22 respectively abut against the opposite sides of the top of the silicon rod 10, and the third abutment 23 abuts against the middle of the top surface of the silicon rod 10, which maximizes the stability of the silicon rod 10 within the clamping space. Furthermore, the third abutment 23 has a notch 231, which provides more movement space for the cutting end of the cutting assembly 7, thereby improving the flexibility of the cutting position of the cutting assembly 7 within the clamping space.

[0055] Please refer to Figure 2 As shown, further, an upper top structure also includes a sensor 4, the detection end of which faces the end of the first top head 21 away from the upper top block 2, or the end of the second top head 22 away from the upper top block 2, or the end of the third top head 23 away from the upper top block 2.

[0056] As can be seen from the above description, when the sensor 4 determines that each of the tops of the upper top block 2 has approached the silicon rod 10, it can use a signal to make the first linear reciprocating device 1 slow down the speed at which the upper top block 2 approaches the silicon rod 10, so as to avoid the upper top block 2 approaching the silicon rod 10 at too high a speed.

[0057] Please refer to Figure 2 As shown, further, an upper top structure also includes a plurality of edge skin tightening devices 5 located on the side of the upper top block 2, the edge skin tightening devices 5 having movable ends that move in the vertical direction.

[0058] As described above, when the cylindrical silicon rod 10 needs to be cut into a rectangular silicon rod 10 by removing the edge skin, the top of the edge skin portion to be removed from the silicon rod 10 is pressed by the movable end of the edge skin clamp 5.

[0059] Please refer to Figure 8 and Figure 9 As shown, the cutting assembly 7 further includes a vertically arranged first mounting plate 71 and wire cutting wheel trains 72 and clamps 73 respectively disposed at both ends of the first mounting plate 71 in the thickness direction. The first mounting plate 71 can move in the vertical direction and the horizontal direction. The first mounting plate 71 is provided with through holes in the thickness direction. The cutting ends of the wire cutting wheel train 72 form a clamping space on the mounting panel. The clamps 73 include clamps that can extend into the clamping space through the through holes.

[0060] As described above, after the first mounting plate 71 drives the wire cutting wheel system 72 to complete the half-cutting operation of the silicon rod 10, the clamp 73 clamps the nearest silicon rod blank away from the other silicon rod blank, so that a wire retraction space is formed between the two silicon rod blanks so that the wire cutting wheel system 72 can move to the top of the silicon rod blank.

[0061] Please refer to Figure 10 As shown, the clamp 73 further includes a second linear reciprocating device 731. The second linear reciprocating device 731 has a movable end that moves parallel to the thickness direction of the first mounting plate 71. At least one layer of clamps is provided on the movable end of the second linear reciprocating device 731 along the length direction parallel to the first mounting plate 71. Preferably, the second linear reciprocating device 731 is a cylinder, and preferably, the movable end of the second linear reciprocating device 731 has two layers of clamps along the length direction parallel to the first mounting plate 71. The two layers of clamps can improve the stability of the clamp 73 in clamping silicon ingot blanks and the flexibility of the clamp 73 in clamping silicon ingot blanks of different lengths.

[0062] Please refer to Figure 10As shown, the clamp further includes a second mounting plate 732 and a wedge 733 slidably disposed on the second mounting plate 732. The second mounting plate 732 is disposed on the movable end of the second linear reciprocating device 731. The moving direction of the wedge 733 is perpendicular to the moving direction of the movable end of the second linear reciprocating device 731. The wedge 733 has a clamping arm 7331 extending out of the surface of the second mounting plate 732. A pad is provided on one end face of the clamping arm 7331 that abuts against the silicon ingot blank to prevent scratching the surface of the silicon ingot blank during clamping.

[0063] As described above, the second linear reciprocating device 731 allows the wedges 733 on the second mounting plate 732 to move closer to or further away from the silicon ingot blank. During the clamping process of the silicon ingot blank, the two wedges 733 come together to clamp the silicon ingot blank.

[0064] Please refer to Figure 10 As shown, the clamp further includes a push-pull block 734 and a driving member 735. The wedge block 733 has a guide elongated hole 7332, which is inclined towards the edge of the second mounting plate 732. The push-pull block 734 has guide posts 7341 that are respectively inserted into the guide elongated holes 7332 of the relatively sliding wedge blocks 733. The movable end of the driving member 735 is connected to the push-pull block 734, and the moving direction of the movable end of the driving member 735 is parallel to the moving direction of the movable end of the second linear reciprocating device 731. Preferably, the driving member 735 is a cylinder.

[0065] As can be seen from the above description, since the distance between the guide posts 7341 on the push-pull block 734 does not change, when the moving end of the drive member 735 controls the movement of the push-pull block 734, it will cause the guide posts 7341 to move within the guide elongated hole 7332 of the wedge block 733, thereby forcing the two wedge blocks 733 to move relative to each other.

[0066] Please refer to Figure 10 As shown, the clamp further includes a guide rail 736 disposed on the surface of the second mounting plate 732, and the wedge 733 is slidably disposed on the guide rail 736.

[0067] As can be seen from the above description, the guide rail 736 can ensure the moving direction of the wedge block 733.

[0068] Please refer to Figure 9As shown, the wire EDM wheel system 72 further includes a cutting wire 721 and a drive wheel 722, a follower wheel 723, and a tension wheel 724 disposed on one end face of the first mounting plate 71 in the thickness direction. The cutting wire 721 is arranged in a ring in the grooves of the drive wheel 722, the follower wheel 723, and the tension wheel 724. Preferably, two follower wheels 723, one drive wheel 722, and one tension wheel 724 are provided. This four-wheel structure can improve the stability of the cutting wire 721 during operation.

[0069] Please refer to Figure 9 As shown, a tensioning mechanism 8 is further provided on the first mounting plate 71. The tensioning mechanism 8 includes a bearing seat 81 and a rotating shaft 82. The bearing seat 81 is provided on the first mounting plate 71. The rotating shaft 82 is rotatably mounted in the bearing seat 81 through a bearing. A connecting arm 821 is eccentrically provided at the end of the rotating shaft 82 away from the bearing seat 81. The connecting arm 821 is connected to the tensioning wheel 724.

[0070] As can be seen from the above description, since the rotating shaft 82 is connected to the tensioning wheel 724 through the connecting arm 821, the degree to which the tensioning wheel 724 tensions the cutting line 721 can be controlled by rotating the rotating shaft 82.

[0071] In one alternative embodiment, a motor is driven to the end of the shaft 82 away from the tension wheel 724.

[0072] In another alternative embodiment, a counterweight is connected to the end of the shaft 82 away from the tension wheel 724.

[0073] Please refer to Figure 9 As shown, further, a blocking member 9 is provided on the through hole of the first mounting plate 71. The two opposite sides of the blocking member 9 are a fixed side and a free side, respectively. The fixed side of the blocking member 9 is connected to the first mounting plate 71, and the direction from the fixed side to the free side of the blocking member 9 is parallel to the length direction of the first mounting plate 71. Preferably, the blocking member 9 is located on the end face of the first mounting plate 71 where the cutting end of the wire cutting wheel system 72 is located.

[0074] As described above, the shielding member 9 is connected to the first mounting plate 71 through a fixed edge. This not only does not affect the clamping of the silicon rod blank through the through hole on the first mounting plate 71, but also prevents the coolant splashed by the wire cutting wheel system 72 during the cutting operation from carrying waste chips through the through hole on the first mounting plate 71 and splashing onto the clamping device 73.

[0075] Please refer to Figure 8 and Figure 11As shown, the lower top block 6 has a second top holding surface, on which a fourth top head 61 corresponding to the first top head 21 is provided, and on which a fifth top head 62 corresponding to the second top head 22 is provided.

[0076] As described above, the lower top block 6 is provided with a fourth top head 61 corresponding to the first top head 21 and a fifth top head 62 corresponding to the second top head 22, which can further improve the stability of the silicon rod 10 between the upper top block 2 and the lower top block 6.

[0077] In one alternative embodiment, a sixth top head 63 corresponding to the third top head 23 is provided on the second top support surface.

[0078] Please refer to Figure 11 As shown, multiple edge tightening devices 5 are provided on the side of the lower top block 6, and the edge tightening device 5 has a movable end that moves in the vertical direction.

[0079] As can be seen from the above description, when it is necessary to cut the edge of the silicon rod 10 into a rectangular shape, the edge clamping device 5 on the lower top block 6 and the edge clamping device 5 on the upper top block 2 can clamp the edge of the silicon rod 10 that has been cut off.

[0080] The present invention provides a method for partial sectioning, comprising a cutting infeed process and a partial sectioning process;

[0081] The feeding process includes step S1: feeding the silicon rod into the clamping space, with the top head on the upper top block 2 and the movable end of the auxiliary clamping device 3 abutting against the top surface of the silicon rod, and the top head of the lower top block 6 abutting against the bottom surface of the silicon rod.

[0082] Step S2: The movable end of the auxiliary clamping device 3 separates from the top surface of the silicon rod;

[0083] Step S3: The cutting end of the cutting component 7 enters from below the movable end of the auxiliary clamping device 3 between the auxiliary clamping device 3 and the first head 21;

[0084] Step S4: The movable end of the auxiliary clamping device 3 abuts against the top surface of the silicon rod;

[0085] Step S5: The first top head 21 separates from the top surface of the silicon rod;

[0086] Step S6: The cutting end of the cutting component 7 enters from below the first top head 21 between the first top head 21 and the second top head 22;

[0087] Step S7: The first top head 21 abuts against the top surface of the silicon rod;

[0088] The half-sectioning process includes step S8: the cutting end of the cutting component 7 cuts from the top end of the silicon rod to the bottom end of the silicon rod until the silicon rod is cut into two silicon rod blanks.

[0089] Furthermore, a half-sectioning method also includes a wire removal process, including step S9: the clamp 73 clamps the closest silicon ingot blank;
