Description

Technical Field

[0001] The present invention relates to the field of material processing equipment, and in particular to an edge skin unloading method, an edge skin unloading unit and a crystal rod cutting system. Background Art

[0002] At present, crystalline silicon solar cells are widely used in the field of photovoltaic power generation due to their high conversion efficiency. Crystalline silicon solar cells are made on high-quality silicon wafers, which are made from pulled or cast silicon rods through a series of processing steps such as wire saw cutting. The existing crystal rod processing system is generally single-station or double-station processing, with low processing efficiency and low production capacity, which cannot meet the needs of cost reduction and efficiency improvement.

[0003] In the process of cutting the crystal rod, unloading the edge skin is one of the important steps. It is necessary to ensure that the edge skin unloading steps are completed quickly and efficiently, and that the unloaded edge skin is intact and undamaged. When unloading the edge skin, the existing crystal rod cutting equipment is limited by the motion interference between the various components of the equipment, and usually can only unload the edge skin by pulling. Specifically, after the edge skin clamps the edge skin, it is necessary to separate the edge skin from the processed crystal rod by pulling in a direction perpendicular to the dividing surface between the crystal rod and the edge skin.

[0004] Since the crystal rod will continuously spray coolant during the cutting process, the liquid will generate a large surface tension at the dividing surface between the crystal rod and the edge skin, which will tightly adsorb the crystal rod and the edge skin together. Therefore, it is difficult to separate the edge skin by pulling. The load on the driving device such as the motor is also large, which is not conducive to the safe and stable operation of the edge skin material unloading device, and may also damage the edge skin.

[0065] Further, if Figures 5 to 9 As shown, the crystal ingot cutting device 4 includes a base 41, a feed assembly 42, a head assembly 43 and a crystal ingot clamping assembly 44. Among them, the base 41 is used to install and support the various components of the crystal ingot cutting device 4 such as the feed assembly 42, and has strong rigidity and stability; a cutting tool is wound around the head assembly 43, and a cutting position is formed on the cutting tool. The cutting tool can cut the crystal ingot under high-speed operation; the head assembly 43 is arranged on the feed assembly 42, and the feed assembly 42 can drive the head assembly 43 to move back and forth in the vertical direction and the horizontal direction to adjust the cutting position on the cutting tool, so that the cutting position corresponds to the part to be cut on the crystal ingot, and the cutting action is performed; the crystal ingot clamping assembly 44 is used to clamp the round crystal ingot to be processed, and can also stably clamp the cut square crystal ingot and the cut edge skin.

[0066] Specifically, Figure 5 and Figure 6 As shown, the base 41 in the crystal rod cutting device 4 is rectangular as a whole, and a first mounting position 411 is provided on the base 41, and the first mounting position 411 is located in the middle of the base 41, and the feed assembly 42 is fixedly arranged at the first mounting position 411 to separate two working rooms on the base 41. The operation of the two working rooms is relatively independent. In the present invention, both working rooms are cutting rooms (a first cutting room and a second cutting room), and the cutting rooms are used to cut the round crystal rods and cut the round crystal rods into square round rods; of course, the two working rooms can also be set to other functions or different functions, for example, the two working rooms can also be set to two grinding room, or set to one cutting room and one grinding room.

[0067] A driving assembly 412 and a sliding assembly 413 are provided on one side of the base 41, and the loading and unloading unit 100 in the ingot cutting system is provided on the side of the base 41 provided with the driving assembly 412 and the sliding assembly 413. The transfer device in the loading and unloading unit 100 is connected to the sliding assembly 413, and the driving assembly 412 can drive the sliding assembly 413 to move, driving the transfer device to reciprocate between the first cutting chamber and the second cutting chamber on the base 41, so as to load or unload materials for the two studios. The two studios share a set of loading and unloading units 100, which can reduce the size of the equipment and save costs.

[0068] As a preferred embodiment, the cutting unit of the crystal rod cutting system can also include three, four or more cutting chambers, preferably a group of two cutting chambers, which are arranged on a base in the following back-to-back manner, and the bases can be interconnected to connect multiple cutting chambers in series to form a production line, forming a workshop layout.

[0069] Specifically, Figures 7 to 9 As shown, the feed assembly 42 in the crystal rod cutting device 4 includes a support frame 421, and the support frame 421 includes a first mounting surface and a second mounting surface arranged opposite to each other, the first mounting surface is arranged in the direction of the first cutting chamber, and the second mounting surface is arranged in the direction of the second cutting chamber. The crystal rod cutting device 4 includes a first head assembly and a second head assembly, the first head assembly is arranged on the first mounting surface, and the second head assembly is arranged on the second mounting surface, the first head assembly and the second head assembly are arranged opposite to each other, and extend from the first mounting surface and the second mounting surface toward the first cutting chamber and the second cutting chamber in a direction away from the feed assembly 42, respectively. The double cutting chambers are arranged in the above manner, which can not only greatly improve the processing efficiency, but also make the overall layout of the crystal rod cutting device 4 more compact and occupy less space.

[0070] Specifically, Fig.10 and Fig.11 As shown, the feeding assembly 42 in the ingot cutting device 4 includes longitudinal feeding and transverse feeding. The longitudinal feeding includes a vertical slide 422 and a vertical slide rail 423 which are slidably connected. The vertical slide rail 423 is installed on the support frame 421 and extends in the vertical direction. The vertical slide rail lead screw is connected to the vertical slide 422. The vertical slide rail lead screw can rotate under the drive of the motor and the reducer, thereby driving the vertical slide 422 to reciprocate in the vertical direction along the vertical slide rail 423.

[0071] The lateral feed includes a lateral slide 424 and a lateral slide rail 425. The lateral slide rail 425 is arranged on the vertical slide 422 and extends in the lateral direction. The lateral slide 424 is slidably connected to the lateral slide rail 425 of the vertical slide 422. A lateral slide rail lead screw is connected to the lateral slide 424. The lateral slide rail lead screw can rotate under the drive of the motor and the reducer, thereby driving the lateral slide 424 to reciprocate in the lateral direction along the lateral slide rail 425.

[0072] Four groups of longitudinal feed and transverse feed are arranged on the support frame 421 of the feed assembly 42, wherein two groups are arranged side by side on the first mounting surface of the support frame 421, and two groups are arranged side by side on the second mounting surface. The first head assembly and the second head assembly respectively include two heads, the two heads in the first head assembly are respectively arranged on the two groups of transverse feed on the first mounting surface of the support frame 421, and are connected to the transverse slide 424 of the transverse feed, and the two heads in the second head assembly are respectively arranged on the two groups of transverse feed on the second mounting surface of the support frame 421, and are connected to the transverse slide 424 of the transverse feed. The transverse feed can drive the head to move back and forth in the transverse direction, adjust the position of the head in the transverse direction, and adjust the spacing distance between the two heads in the same group; the longitudinal feed can drive the transverse feed and the head to move back and forth in the vertical direction to cut the crystal rod placed between the two heads.

[0073] With the above arrangement, the feed assembly can respectively drive the two heads of the first head assembly and the second head assembly to move and cut the crystal rod to be processed, so that the operation of the first cutting chamber and the second cutting chamber is relatively independent.

[0074] like Fig.11 As shown, a fan 426 is provided on the longitudinal feed, and the fan 426 is provided close to the vertical slide rail 423 and the vertical slide rail lead screw. Preferably, one or more fans 426 are provided corresponding to each longitudinal feed. The fan 426 can continuously deliver fresh air to the space where the vertical slide rail 423 and the vertical slide rail lead screw of the longitudinal feed are located during the crystal rod cutting process, so as to ensure that the air in this area is dry as much as possible, thereby preventing the vertical slide rail 423 and the vertical slide rail lead screw from being corroded by moisture, which affects the operation accuracy and operation safety of the machine head.

[0075] like Figure 12 to Figure 14 As shown, a balancing assembly 427 is also provided on the longitudinal feed, and the balancing assembly 427 can reduce the load of the longitudinal feed, and prevent the head assembly connected to the longitudinal feed from accidentally falling off and causing a safety accident. Specifically, the balancing assembly 427 includes a fixed pulley 61, a fixed pulley seat 62, a movable pulley 63, a movable pulley seat 64 and a balancing oil cylinder 65, wherein the fixed pulley seat 62 is fixedly arranged on the upper part of the feed assembly support frame 421, the fixed pulley 61 is arranged on the fixed pulley seat 62, the balancing oil cylinder 65 is arranged on the lower part of the feed assembly support frame 421, the movable pulley seat 64 is connected to the piston rod of the balancing oil cylinder 65, and the movable pulley 63 is arranged on the movable pulley seat 64. A chain 66 is wound around the fixed pulley 61 and the movable pulley 63, the chain head end 67 is fixedly connected to the fixed pulley seat 62, and the chain tail end 68 is fixedly connected to the vertical slide 422 of the feed assembly.

[0076] When the feed assembly is working, the piston rod of the balancing oil cylinder 65 will move synchronously with the movable pulley 63 and the movable pulley seat 64, and the chain tail 68 of the chain 66 will move synchronously with the vertical slide 422 of the feed assembly. The chain tail 68 fixedly connected to the vertical slide 422 will bear the gravity of the lateral feed and the head assembly, and the gravity will be transmitted to the movable pulley 63 through the fixed pulley 61. According to the mechanical characteristics of the movable pulley group, the movement stroke of the movable pulley 63 is half of the movement stroke of the chain tail 68, so the tension borne by the movable pulley 63 is twice the force borne by the chain tail 68. Therefore, under the pulling force of the balancing oil cylinder 65, the vertical slide 422 of the feed assembly will be subjected to an upward pulling force to balance a part of the lateral feed and the gravity of the head assembly itself, so as to prevent the head assembly from accidentally falling.

[0077] Preferably, a hinge seat is provided on the support frame 421 of the feed assembly, and a hinge shaft 69 is provided at the bottom of the balancing oil cylinder 65, and the hinge shaft 69 is hinged on the hinge seat to connect the balancing oil cylinder 65 with the support frame. The connection between the hinge shaft 69 and the hinge seat can not only fix the position of the balancing oil cylinder 65, but also provide a certain swing space for the balancing oil cylinder 65 to prevent the balancing oil cylinder 65 from being damaged when subjected to a tilting pulling force.

[0078] An induction switch is also provided at the lower part of the longitudinal feeding feed assembly 42. The first head assembly and / or the second head assembly feeds and cuts from top to bottom along the vertical direction. When the crystal rod cutting action is completed, the induction switch provided at the lower part is triggered to automatically stop the cutting action.

[0079] The head assembly 43 includes at least one head, which includes a head frame. A driving wheel assembly is provided on the head frame for driving the cutting tool to rotate at high speed. A cutting position for cutting the crystal rod to be processed is formed on the driving wheel assembly. The head frame is preferably a rectangular frame structure, a clamping space is formed in the middle, and an opening is provided on the side of the head frame. The opening forms a sliding space on one side of the head frame. The edge skin generated by the head cutting the crystal rod to be processed can be clamped through the clamping space on the head frame, and can be slid laterally through the sliding space to separate from the processed crystal rod.

[0080] Specifically, Figures 7 to 9 , Figures 15 to 17 As shown, the head assembly 43 includes a first head assembly and a second head assembly respectively arranged on both sides of the support frame 421 of the feed assembly 42. Since the first head assembly and the second head assembly have the same structure, the specific structure of the head assembly 43 is described in detail below taking the first head assembly as an example.

[0081] The first head assembly includes a first head 431 and a second head 432 arranged side by side, the head frames 433 of the first head 431 and the second head 432 are parallel to each other and opposite to each other, and a cutting station for placing the crystal rod to be processed is arranged between the first head 431 and the second head 432. The cutting positions on the first head 431 and the second head 432 are arranged opposite to each other, and both sides of the round crystal rod to be processed can be cut at the same time. The first machine head 431 and the second machine head 432 have basically the same structure. Specifically, the first machine head 431 includes a machine head frame 433, on which a driving wheel assembly 434, a tension wheel assembly 435 and a driven wheel assembly 436 are arranged in a ring shape, and a ring-shaped cutting tool (not shown in the figure) is sleeved on the outside; the driving wheel assembly 434 can drive the ring-shaped cutting tool to rotate at high speed to generate cutting force, the tension wheel assembly 435 can adjust the position of the rotation axis, and then adjust the tension of the ring-shaped cutting tool, and the driven wheel assembly 436 can cooperate with the driving wheel assembly 434 and the tension wheel assembly 435 to assist the cutting tool to rotate smoothly at high speed. The cutting tool can be a cutting member such as a diamond wire and a saw belt that can be used to cut high-hardness and brittle materials.

[0082] In the present invention, the cutting tool can form relative friction with the workpiece to be cut while moving at high speed, thereby achieving cutting of the workpiece to be cut. For example, the cutting tool can be a cutting member such as a diamond wire and a saw belt that can be used to cut high-hardness and brittle materials, wherein the diamond wire is also called a diamond cutting wire, which is a diamond cutting wire made by embedding tiny diamond particles on the cutting wire; the saw belt is a processing tool made by electroplating diamond on the cutting belt, which can be used for straight and curved cutting.

[0083] like Fig.15 As shown, the head frame 433 is a single-side opening structure, such as a C-shaped structure. Specifically, the head frame 433 is rectangular as a whole, including a fixed side arranged along the vertical direction, and the fixed side is fixedly connected to the horizontal slide 424 on the support frame 421 of the feed assembly 42; the head frame 433 also includes an opening portion 437 opposite to the fixed side, and the opening portion 437 is arranged on the side of the head frame 433 away from the feed assembly 42, and the opening portion 437 makes the head frame 433 form a C-shaped structure as a whole. The head frame 433 with a single-side opening can enable the edge skin material unloading device 5 in the crystal rod cutting system to slide and remove the cut crystal rod edge skin from the opening portion 437 of the head frame 433 by lateral sliding, so that the edge skin unloading is more convenient and quick, and the edge skin is not easily damaged.

[0084] The driving wheel assembly 434 includes two or more driving wheels, which are arranged side by side on the lateral sides of the lower part of the head frame 433, and a cutting position for cutting the crystal rod to be processed is formed between two adjacent driving wheels. When the cutting tool rotates at high speed, the part of the cutting tool located between two adjacent driving wheels can cut the crystal rod, and one cutting position is used to cut one side of a crystal rod. Correspondingly, at least two cutting stations can be set in each cutting chamber, and the number and setting positions of the cutting positions on the head frame correspond to the number and setting positions of the cutting stations in the cutting chamber, so that each cutting chamber can cut at least two crystal rods to be processed at the same time.

[0085] The second head 432 has a substantially identical structure to the first head 431. To further improve the processing efficiency, Fig.16 As shown, in the present invention, the cutting positions on the first head 431 and the second head 432 are arranged relatively to each other so as to cut two opposite sides of a crystal rod at the same time; Fig.15 As shown, the driving wheel assembly 434 of the first head 431 and the second head 432 respectively includes three driving wheels arranged side by side, and two cutting positions can be formed between the three driving wheels to simultaneously cut two crystal rods placed side by side. That is, the head frames and driving wheels of the first head 431 and the second head 432 are located opposite to each other, and the first head assembly composed of the first head 431 and the second head 432 can simultaneously cut the two sides of the two crystal rods to be processed on the cutting station.

[0086] The driving wheel assembly 434 of the first head 431 and the second head 432 is preferably as follows Fig.15 The three driving wheels shown in the figure, too few driving wheels will reduce the number of cutting positions and affect the cutting efficiency, too many driving wheels will increase the load of the head frame 433 and affect the stability and safety of the processing process. Setting three driving wheels can improve the cutting efficiency while ensuring the cutting quality and ensure the stability and safety of the cutting process.

[0087] Preferably, among the three driving wheels of the driving wheel assembly 434, the setting position of the driving wheel located in the middle position is lower than the setting position of the driving wheels on both sides. This setting method can form a line contact between the cutting tool and the driving wheel located in the middle position, increase the contact area, and further enhance the transmission effect of the driving wheel on the cutting tool, avoiding slipping. At the same time, it can also strengthen the support effect on the middle position of the cutting tool.

[0088] like Fig.15As shown, a cleaning component is also provided on the head frame 433, and the cleaning component includes at least two nozzles, and the number of nozzles is the same as the number of driving wheels in the driving wheel assembly 434. A nozzle is provided on the side of each driving wheel, and the nozzle can spray cleaning liquid toward the driving wheel and the cutting tool close to the driving wheel to clean and cool the driving wheel and the cutting tool. The cleaning component can avoid the accumulation of crystal rod debris on the driving wheel, ensure the cutting effect, keep the head assembly clean and beautiful, and facilitate the replacement of parts. In addition, a protective baffle is provided at the top corner of the head frame 433, and the protective baffle can cover and protect each wheel group installed on the head frame 433. A drive component 412 such as a motor and a reducer is also provided on the head frame 433 to provide power for the driving wheel assembly 434.

[0089] Preferably, the head frame 433 includes three long box structures, the middle of the three box structures are hollow, and the ends of the three box structures are welded and fixed to form a head frame 433 with a single-side opening and a hollow interior. Compared with the general casting structure, this type of head frame 433 has better overall strength, stronger rigidity and better stability. Fig.17 As shown, a connecting pipe is provided on the head frame 433, and the connecting pipe passes through the box structure constituting the head frame 433 to connect the two opposite side walls of the box structure to each other. The driving wheel assembly 434, the driven wheel assembly 436 and the tension wheel assembly 435 on the head frame 433 all include an axle box, and the axle box is arranged in the connecting pipe. The connecting pipe can provide support for the axle box and can also further improve the overall strength of the head frame 433.

[0090] Further, if Figures 18 to 20 As shown, as a preferred embodiment, a support frame 438 is also provided on the head frame 433. The support frame 438 is a slender rod structure, which is provided at the opening portion 437 of the head frame 433. The support frame 438 is supported at the single-side opening structure portion of the head frame 433 to make the overall structure of the head frame 433 more stable. At the same time, the support frame 438 is installed with an offset toward the direction of the crystal rod to be processed, so that the opening portion 437 of the head frame 433 forms a movement space on the side away from the crystal rod. With this arrangement, sufficient movement space for unloading the edge skin can be reserved for the edge skin material unloading device 5 in the crystal rod cutting system, so that the edge skin material unloading device 5 can unload the edge skin by lateral sliding.

[0091] Specifically, Fig.19 As shown, a connecting plate is provided in the opening portion 437 of the head frame 433, the first end of the connecting plate is fixedly connected to the side wall of the head frame 433, and the second end is extended toward the direction of the crystal rod to be processed, and the support frame 438 is fixedly connected to the second end of the connecting plate so that the support frame 438 is offset and installed toward the side close to the crystal rod.

[0092] Further, if Fig.16 As shown, as a preferred embodiment, the driving wheel assembly 434 on the head frame 433 of the first head 431 includes a driving wheel and an axle box, the driving wheel is used to wrap around the cutting tool and drive the cutting tool to rotate at high speed, one end of the axle box is connected to the head frame, and the other end is connected to the driving wheel, the axle box is an extended axle box 439, the length of the extended axle box 439 is greater than the length of the ordinary axle box, and the extended axle box 439 is extended in the direction away from the head frame 433 to form a cutting space between the head frame 433 and the position on the driving wheel for wrapping the cutting tool.

[0093] Correspondingly, the driven wheel assembly 436 and the tension wheel assembly 435 each include an extended shaft box 439, which is extended in a direction away from the machine head frame 433. Preferably, the extended shaft boxes 439 of the driving wheel assembly 434, the driven wheel assembly 436 and the tension wheel assembly 435 have the same extension length. An annular cutting tool can be sleeved on the driving wheel assembly 434, the tension wheel assembly 435 and the driven wheel assembly 436, and a cutting space is formed between the position on the driving wheel assembly 434, the driven wheel assembly 436 and the tension wheel assembly 435 for winding the cutting tool and the machine head frame 433, that is, a cutting space is formed between the cutting tool wound on the driving wheel assembly 434, the driven wheel assembly 436 and the tension wheel assembly 435 and the machine head frame 433.

[0094] The above cutting space can be used for half-rod cutting of the crystal rod, such as Fig.28 As shown, in some specific crystal rod cutting processes, it is necessary to cut the processed square rod from the middle to form two half rods. Half-rod cutting usually needs to be completed by special cutting equipment, and the above-mentioned setting structure of the first head 431 can enable the crystal rod cutting device to not only realize the square opening of the round rod, but also perform half-rod cutting, thereby increasing the cutting function and improving the processing efficiency. Specifically, the working process of half-rod cutting is as follows: after the crystal rod cutting device cuts the round rod into a square rod, the position of the first head 431 in the horizontal direction is adjusted by the horizontal feed in the feed assembly 42, so that the cutting tool is aligned with the middle part of the square rod, and then the longitudinal feed in the feed assembly 42 drives the first head 431 to move vertically downward. At this time, the cutting space between the cutting tool and the head frame 433 can allow the half rod to pass through, thereby enabling the first head 431 to complete the half-rod cutting process.

[0095] It should be noted that the structural design of the head assembly for cutting half rods can be applied not only to the C-shaped head frame, but also when the head is a general rectangular frame or other structural forms, a cutting space for cutting half rods can be formed between the cutting tool and the head frame by setting an extended shaft box 439. When the head frame is a closed rectangular frame including four side edges, the head frame is preferably formed by welding and fixing the ends of four hollow long strip box structures to form a rectangular head frame with a hollow interior. The extended shaft box 439 of the driving wheel assembly 434, the driven wheel assembly 436 and the tension wheel assembly 435 is arranged in the connecting pipe of the head frame, and the connecting pipe can provide support for the extended shaft box 439.

[0096] Preferably, the extended shaft box 439 and the cutting space are arranged on the first head 431 or the second head 432 to reduce the overall volume of the first head assembly. When cutting a half stick, only the head with the extended shaft box 439 and the cutting space needs to be moved and cut. Of course, the extended shaft box 439 and the cutting space can also be arranged on both the first head 431 and the second head 432.

[0097] Furthermore, the crystal rod clamping assembly 44 in the crystal rod cutting device 4 includes a fixed clamp 441 and a movable clamp 442. The fixed clamp 441 can be against the end face of the lower end of the crystal rod, and the movable clamp 442 can be against the end face of the upper end of the crystal rod to jointly clamp the crystal rod, making it convenient for the head assembly 43 to perform cutting action.

[0098] like Figure 5 and Figure 6 As shown, the fixed chuck 441 is arranged on the base 41, and is located between the first head 431 and the second head 432 of the first head assembly. The fixed chuck 441 includes a lower chuck, a side skin lower support assembly, and a driving device. The lower chuck abuts against the middle position of the lower end face of the crystal rod, and can tilt and move within a certain angle range. When the lower end face of the crystal rod is not completely horizontal, it can also adapt to the tilted lower end face of the crystal rod, so that the crystal rod always maintains a vertical clamping state. The side skin lower support assembly abuts against the edge of the crystal rod, and is used to support the lower end face of the side skin. It can cooperate with the dynamic chuck 442 to clamp the side skin during the cutting process to prevent the side skin from tilting and falling.

[0099] Each fixed chuck 441 corresponds to a cutting station. In the present invention, there are two cutting chambers in total, each of which includes two cutting stations, that is, there are four fixed chucks 441, two fixed chucks 441 are arranged in each cutting chamber, and the two fixed chucks 441 are arranged side by side between the two heads of the head assembly 43.

[0100] like Fig.21 and Fig. 22As shown, the movable chuck 442 is correspondingly arranged above the fixed chuck 441, including an upper chuck 443, an edge skin upper support device 444, a vertical motion component 445 and a driving device. The upper chuck 443 abuts against the middle position of the upper end face of the crystal rod, and can tilt and move within a certain angle range. When the upper end face of the crystal rod is not completely horizontal, it can also adapt to the inclined upper end face of the crystal rod, so that the crystal rod always maintains a vertical clamping state. The edge skin upper support component abuts against the edge of the crystal rod, which is used to support the upper end face of the edge skin. It can cooperate with the fixed chuck 441 to clamp the edge skin during the cutting process to prevent the edge skin from tilting and falling. The vertical motion component 445 can drive the upper chuck 443 to move up and down. When the crystal rod is transported to the cutting station, the lower end face of the crystal rod is first placed on the fixed chuck 441, and then the movable chuck 442 moves vertically downward to press the upper end face of the crystal rod to achieve the clamping and fixing of the crystal rod.

[0101] Each cutting chamber includes two cutting stations, one cutting station is arranged near the fixed side of the head frame 433, and the other cutting station is arranged near the opening portion 437 of the head frame 433. The vertical movement component 445 of the dynamic chuck 442 corresponding to the cutting station near the fixed side of the head frame 433 is arranged on the support frame 421 of the feed assembly 42, and the vertical movement component 445 of the dynamic chuck 442 corresponding to the cutting station near the opening portion 437 of the head frame 433 is arranged on the side column, and the side column is arranged near the first head 431 and the second head 432 away from the feed assembly 42. Specifically, the side column is fixedly arranged at the second installation position of the base 41, and the second installation position is located on the side of the base 41 away from the feed assembly 42. The vertical motion assembly 445 includes a vertical feed and a chuck frame 446. One end of the chuck frame 446 is movably connected to the vertical feed, and the other end is extended toward the direction of the cutting station. The upper chuck 443 and the edge skin upper support device 444 are arranged on the chuck frame 446. The two movable chucks 442 in the same cutting chamber are arranged in opposite positions, with a compact structure and small space occupation.

[0102] The driving devices on the fixed chuck 441 and the movable chuck 442 can respectively drive the upper chuck 443 and the lower chuck to rotate. When the head assembly 43 completes the first cutting, the edge skin of two sides of the round crystal rod can be cut off. After the edge skin material unloading device 5 takes away the edge skin, the driving device drives the upper and lower chucks to rotate, driving the crystal rod to rotate 90 degrees on the spot. The head assembly 43 performs a second cutting, and the edge skin of the other two sides of the crystal rod can be cut off to obtain a square rod.

[0103] The fixed chuck 441 is preferably detachably arranged on the base 41. When it is necessary to use the crystal rod cutting system cutting unit to perform half-rod cutting, the fixed chuck 441 can be replaced with a half-rod cutting chuck. After the square rod is cut, two half-rods are formed. The half-rod cutting chuck can support and clamp the two half-rods respectively to improve the stability of the crystal rod clamping during the half-rod cutting process.

[0104] Furthermore, the edge material unloading device 5 in the cutting unit of the crystal rod cutting system includes a translation assembly, a centering assembly and a clamping jaw assembly. The translation assembly is arranged close to the head assembly 43, the centering assembly is movably connected to the translation assembly, and the clamping jaw assembly is arranged on the centering assembly. The centering assembly can slide along the translation assembly to drive the clamping jaw assembly to approach or move away from the head assembly 43. The clamping jaw assembly can clamp the edge material cut off by the head assembly 43 at the cutting station and remove the edge material.

[0105] Specifically, Figure 1 and Figure 2 As shown, the extension direction of the first head assembly and the second head 432 assembly is defined as a first direction X. In the horizontal direction, the direction perpendicular to the first direction X is defined as a second direction Y. In the vertical direction, the direction perpendicular to the first direction X is defined as a third direction Z.

[0106] like Figures 1 to 3 , Figure 23 to Figure 25 As shown, the translation assembly includes a truss body 51 and a plurality of support columns 52, the truss body 51 includes a first truss 511, a second truss 512, a third truss 513 and a fourth truss 514 extending along a first direction X, wherein the first truss 511 and the second truss 512 are parallel to each other and opposite to each other, and are respectively arranged on both sides of the first head assembly, corresponding to the first cutting chamber; the third truss 513 and the fourth truss 514 are parallel to each other and opposite to each other, and are respectively arranged on both sides of the second head assembly, corresponding to the second cutting chamber; the ends of the first truss 511 and the third truss 513 are connected, and the ends of the second truss 512 and the fourth truss 514 are connected. A plurality of support columns 52 are respectively arranged on the first truss 511, the second truss 512, the third truss 513 and the fourth truss 514, and one end of the support column 52 is connected to the truss body 51, and the other end is connected to the base 41 to support and fix the truss body 51, so that the truss body 51 is surrounded by the outside of the crystal rod cutting device 4 including the first head assembly and the second head assembly.

[0107] A first centering component 53 is arranged between the first truss 511 and the second truss 512, and a first clamp 531 and a second clamp 532 are arranged on the first centering component 53. The first centering component 53 can reciprocate along the first direction X on the first truss 511 and the second truss 512 to drive the first clamp 531 and the second clamp 532 to approach or move away from the first head component. The first clamp 531 and the second clamp 532 can reciprocate along the second direction Y on the first centering component 53 to approach the crystal rod in the first cutting chamber and clamp the edge skin.

[0108] A second centering component 54 is arranged between the third truss 513 and the fourth truss 514, and a third clamp and a fourth clamp are arranged on the second centering component 54. The second centering component 54 can reciprocate along the first direction X on the third truss 513 and the fourth truss 514 to drive the third clamp and the fourth clamp to approach or move away from the second head component. The third clamp and the fourth clamp can reciprocate along the second direction Y on the second centering component 54 to approach the crystal rod in the second cutting chamber and clamp the edge skin.

[0109] In the above-mentioned edge skin material unloading device 5, the first truss 511, the second truss 512, the first centering assembly 53, the first clamping jaw 531 and the second clamping jaw 532 together constitute the first edge skin unloading assembly, and the third truss 513, the fourth truss 514, the second centering assembly 54, the third clamping jaw and the fourth clamping jaw together constitute the second edge skin unloading assembly. The first edge skin unloading assembly is arranged on the side of the first head assembly away from the feeding assembly 42, and the second edge skin unloading assembly is arranged on the side of the second head assembly away from the feeding assembly 42, that is, the first edge skin unloading assembly and the second edge skin unloading assembly can perform the edge skin unloading process on both sides of the crystal rod cutting device 4 respectively. This arrangement can not only greatly improve the efficiency of the edge skin unloading process, thereby improving the overall work efficiency of the crystal rod cutting process, but also make full use of the assembly space, so that the overall structure of the edge skin material unloading device 5 is very compact, and the overall occupied space of the equipment is reduced.

[0110] Furthermore, since the specific structures of the first side skin unloading assembly and the second side skin unloading assembly are the same, and the mutual cooperation manners with the first head assembly and the second head assembly are also the same, only the first side skin unloading assembly is taken as an example to further explain in detail the specific structure of the side skin material unloading device 5 and the mutual cooperation manner with the first head assembly.

[0111] Specifically, the first centering assembly 53 in the first side skin unloading assembly includes a centering beam 533, which is erected between the first truss 511 and the second truss 512. The first truss 511 and the second truss 512 are provided with a first sliding assembly, and the two ends of the centering beam 533 are respectively slidably connected with the first truss 511 and the second truss 512 through the first sliding assembly. The driving device can drive the centering beam 533 to move horizontally along the first truss 511 and the second truss 512 through the first sliding assembly. The first sliding assembly is preferably a gear rack structure.

[0112] Two sets of second sliding assemblies are arranged on the centering beam 533, and the first clamping jaw 531 and the second clamping jaw 532 are respectively connected to one set of second sliding assemblies, and can be driven by the second sliding assemblies to move horizontally along the extension direction of the centering beam 533. The second sliding assembly is preferably a screw guide structure.

[0113] like Fig.24As shown, the first clamping jaw 531 includes an upper clamping jaw and a lower clamping jaw, and the upper clamping jaw and the lower clamping jaw can move up and down along the third direction Z, thereby clamping the side skin from the upper end and the lower end of the side skin to achieve unloading of the side skin. The structure of the second clamping jaw 532 is the same as that of the first clamping jaw 531. The first clamping jaw 531 and the second clamping jaw 532 can simultaneously unload the two side skins of the crystal rod from both sides of the first head assembly.

[0114] Further, if Fig.29 As shown, in the present invention, the edge skin unloading device 5 has an outstanding advantage, that is, by cooperating with the head assembly 43, the edge skin unloading device 5 can clamp the edge skin when unloading the edge skin, and slide laterally along the dividing surface between the crystal rod and the edge skin, slide the edge skin away from the processed crystal rod, and then transport it to the edge skin collecting device 6.

[0115] When unloading the edge skin, the existing crystal rod cutting equipment is limited by the interference between the head assembly 43 and the edge skin material unloading device 5, and usually can only unload the edge skin by pulling. Fig.30 As shown, after the edge skin clamping claws clamp the edge skin, they directly separate the edge skin from the processed crystal rod by positive pulling in a direction perpendicular to the dividing surface between the crystal rod and the edge skin. Since the crystal rod will be continuously sprayed with coolant during the cutting process, the liquid will generate a large surface tension at the dividing surface between the crystal rod and the edge skin, and the crystal rod and the edge skin will be tightly adsorbed together. Therefore, the separation of the edge skin by pulling needs to overcome the surface tension of water, which requires a large force and is relatively difficult. The load of the driving device such as the motor is also large, which is not conducive to the safe and stable operation of the edge skin material unloading device 5, and may also damage the edge skin.

[0116] The edge material unloading device 5 of the present invention can be as follows Fig.29 As shown, the side skin is unloaded by "lateral sliding". The sliding motion can greatly reduce the adverse effect of surface tension on the side skin unloading process. The force required for side skin unloading is smaller, making the side skin separation process easier, the load on the drive device smaller, and the side skin unloading process more stable and safe.

[0117] Specifically, in order to enable the cutting unit of the ingot cutting system to have the above-mentioned advantages in terms of edge skin unloading, the technical solution adopted is as follows:

[0118] The cutting unit of the crystal rod cutting system includes a side skin unloading unit, which can unload the side skin cut from the crystal rod by lateral sliding.

[0119] Specifically, Figure 1 and Fig.25As shown, in the first cutting chamber, the edge skin unloading unit includes the first head 431 and the second head 432 in the above-mentioned first head assembly, and the first truss 511, the second truss 512, the centering beam 533, the first clamp 531 and the second clamp 532 in the above-mentioned first edge skin unloading assembly, wherein the first head 431 and the second head 432 are arranged side by side, and at least one cutting station is arranged between the first head 431 and the second head 432.

[0120] During the side skin unloading process, in the first step, the first clamp 531 and the second clamp 532 need to be moved to the two sides of the first head assembly respectively, that is, to the outside of the first head 431 and the second head 432 respectively. In order to avoid movement interference between the first side skin unloading assembly and the first head assembly, the specific setting method is: in the horizontal direction, the first truss 511 and the second truss 512 are respectively located on the outside of the first head 431 and the second head 432; in the vertical direction, the first truss 511, the second truss 512 and the centering beam 533 are set at a higher height than the head frame 433 of the first head 431 and the second head 432, thereby forming a driving space between the first truss 511 and the second truss 512, and forming an unloading space below the first truss 511, the second truss 512 and the centering beam 533, and the driving space is located above the unloading space.

[0121] When the first head assembly completes a cutting action, the first head 431 and the second head 432 move to a position close to the base 41 at the same time. At this time, the first head 431 and the second head 432 are located in the unloading space, and the centering beam 533 can move in the driving space above the unloading space, driving the first clamp 531 and the second clamp 532 to move to the outside of the first head 431 and the second head 432 respectively, without interfering with the movement of the first head 431 and the second head 432.

[0122] In the second step, after the first clamp 531 and the second clamp 532 move to the outside of the first head 431 and the second head 432 respectively, the first clamp 531 and the second clamp 532 need to clamp the edge skin cut by the first head 431 and the second head 432 respectively. In order to avoid movement interference, the specific setting method is: a clamping space is formed in the middle of the head frame 433 of the first head 431 and the second head 432, and the first clamp 531 and the second clamp 532 can extend from the outside of the first head 431 and the second head 432 to the inside of the first head 431 and the second head 432 through the clamping space, and then clamp the edge skin.

[0123] In the third step, after the first clamp 531 and the second clamp 532 clamp the edge skin, in order to achieve "lateral sliding" to unload the edge skin, the first clamp 531 and the second clamp 532 need to move in the clamping space of the head frame 433 along the first direction X toward the direction away from the feed assembly 42. In order to avoid the first clamp 531 and the second clamp 532 from interfering with the head frame 433 in motion, the preferred setting method is: an opening portion 437 is provided on the head frame 433 of the first head 431 and the second head 432, so that the head frame 433 forms a C-shaped structure, and the opening portion 437 allows the head frame 433 to form a sliding space on the side away from the feed assembly 42, and the first clamp 531 and the second clamp 532 can avoid interference in motion through the sliding space.

[0124] In addition, in order to further reduce the motion interference problem that may occur during the unloading process of the edge skin, the first clamping jaw 531 and the second clamping jaw 532 preferably adopt the following motion mode:

[0125] like Fig.26 As shown, L1 is the clamping path for the clamp to enter the machine head, and L2 is the unloading path for the clamp to move out of the machine head. The clamp first moves to the outside of the machine head along the first direction X, and then moves along the second direction Y, passes through the machine head frame 433, and clamps the edge skin; after the clamp clamps the edge skin, it first moves a distance along the first direction X toward the opening 437 of the machine head frame 433, so that the edge skin and the crystal rod are slid and separated; then it moves a distance along the second direction Y in the direction away from the crystal rod, so that the edge skin and the crystal rod are offset in the second direction Y; finally, it moves along the first direction X toward the opening 437 of the machine head frame 433 until it moves out of the machine head, completing the unloading of the edge skin. This unloading method is particularly suitable for the case where two or more cutting stations are arranged side by side between the first machine head 431 and the second machine head 432, and can effectively avoid mutual interference between the stations.

[0126] In the above preferred embodiment, the head frame is a single-side opening structure, and the lateral sliding direction when the side skin is unloaded is sliding along the first direction X toward the side away from the feed assembly. In addition, when the head frame is a rectangular frame in the shape of a "mouth" or other frame structure without a lateral opening structure, a sliding space can be formed between the head frame and the cutting station by appropriately increasing the spacing between the head frame and the cutting station. At this time, the side skin can be unloaded by sliding laterally along the first direction X toward the side away from the feed assembly, or by sliding laterally toward the side close to the feed assembly. When two cutting stations are arranged between the first head and the second head arranged side by side, the sliding space can also be formed between the two cutting stations.

[0127] However, setting the machine head frame as a single-side open structure to form a sliding space is a more preferred implementation method, because the edge skin collection device for storing the edge skin is located on the side of the cutting chamber away from the feed assembly, so the edge skin unloading path is shorter and more efficient. While the form of appropriately increasing the distance between the machine head frame and the cutting station can also achieve lateral sliding unloading of the edge skin, it will increase the overall volume of the machine head frame, increase the cost, and is not conducive to the stable operation and miniaturization design of the equipment. In addition, the reverse sliding unloading method will increase the length of the edge skin unloading path, which is not conducive to improving the unloading efficiency.

[0128] The above-mentioned sliding space is preferably capable of allowing the side skin to completely slide and separate from the processed crystal rod when sliding sideways, and the force required to unload the side skin is minimal. Of course, the sliding space can also be set to allow the side skin to partially slide and separate from the processed crystal rod when sliding sideways. After the side skin is partially separated from the processed crystal rod, the side skin can be unloaded by direct pulling, which can also reduce the adverse effects of the surface tension of part of the water and improve the effect of unloading the side skin.

[0129] The second head assembly and the second edge skin unloading assembly in the cutting unit of the crystal rod cutting system can be arranged in the same matching manner to form an edge skin unloading unit with the same function and effect.

[0130] Further, if Figures 1 to 4 As shown, the cutting unit of the ingot cutting system further includes a shavings collecting device 6, and the shavings unloaded by the shavings unloading device 5 can be temporarily stored in the shavings collecting device 6. Preferably, the shavings collecting device 6 includes two shavings collecting devices, which are respectively arranged on the sides of the first cutting chamber and the second cutting chamber, and respectively cooperate with the first shavings unloading assembly and the second shavings unloading assembly to further improve the working efficiency of the shavings unloading process, thereby improving the overall processing efficiency of the cutting unit of the ingot cutting system.

[0131] In combination with the above description of the edge material unloading device 5 and the edge material unloading unit, the edge material unloading method involved in the cutting unit 200 is described in detail.

[0132] Taking two cutting stations arranged between a group of heads as an example, the two cutting stations are arranged side by side along the extension direction of the first head assembly and the second head assembly, wherein the one far away from the opening 437 of the head frame 433 is the first cutting station, and the one close to the opening 437 of the head frame 433 is the second cutting station. The edge skin unloading method specifically includes the following steps:

[0133] Step 1: After the head assembly 43 moves downward from top to bottom and the cutting action of the two crystal bars on the first cutting station and the second cutting station is completed, the centering beam 533 moves along the first direction X on the truss body toward the head assembly 43, so that the two clamping jaws in the clamping jaw assembly move to the two sides of the head assembly 43 respectively, and align with the position of the crystal bar and the edge skin on the first cutting station in the second direction Y;

[0134] Step 2: The two clamping jaws in the clamping jaw assembly move on the centering beam 533 along the second direction Y toward the first cutting station until the two clamping jaws reach positions where they can clamp the side skins of both sides of the crystal rod;

[0135] Step 3: After the two clamping claws clamp the side skins on both sides respectively, the centering beam 533 moves on the truss body along the first direction X in a direction away from the head assembly 43, so that the side skins are slidably separated from the crystal rod;

[0136] Step 4: After the edge skin and the crystal rod are slid and separated, the two clamping claws move on the centering beam 533 along the second direction Y in a direction away from the first cutting station, so that the edge skin and the crystal rod are offset and separated from each other in the second direction Y;

[0137] Step 5: The centering beam 533 drives the clamping claw assembly holding the edge skin to move along the first direction X in a direction away from the head assembly 43. The head assembly 43 is formed with an opening 437. The centering beam 533 drives the clamping claw assembly to move the edge skin out of the head assembly 43 through the opening 437.

[0138] Step 6: The centering beam 533 continues to drive the clamping jaw assembly to move, and transports the edge skin to the edge skin material collecting device 6;

[0139] Step 7: The centering beam 533 moves on the truss body along the first direction X toward the head assembly 43, so that the two clamping jaws in the clamping jaw assembly move to the two sides of the head assembly 43 respectively, and align with the positions of the crystal rod and the edge skin on the second cutting station in the second direction Y;

[0140] Step eight, the two clamping jaws in the clamping jaw assembly move on the centering beam 533 along the second direction Y toward the second cutting station until the two clamping jaws reach positions where they can clamp the side skins of both sides of the crystal rod;

[0141] Step nine, after the two clamping claws clamp the side skins on both sides respectively, the centering beam 533 moves on the truss body along the first direction X in a direction away from the head assembly 43, so that the side skins are slidably separated from the crystal rod;

[0142] Step ten, the centering beam 533 continues to drive the clamping jaw assembly to move along the first direction X in a direction away from the head assembly 43, and moves the edge skin out of the head assembly 43 through the opening 437 on the head assembly 43, and then transports the edge skin to the edge skin material collecting device 6.

[0143] The edge skin unloading method, edge skin unloading unit and crystal rod cutting system of the present invention have the following advantages:

[0144] 1. The edge material unloading device is arranged outside the crystal rod cutting device, which makes full use of the assembly space, makes the overall structure of the cutting unit more compact, reduces the space occupied by the equipment, and the two cutting chambers of the crystal rod cutting device can unload the edge material separately, thereby improving the processing efficiency.

[0145] 2. The side skin material unloading device cooperates with the C-shaped structure of the machine head assembly to realize lateral sliding unloading of the side skin, which greatly reduces the adverse effect of the surface tension of the liquid on the side skin unloading process, makes the side skin separation process easier, reduces the load on the drive device, and makes the side skin unloading process more stable and safe, thereby improving the processing efficiency and processing quality.
