Description

Technical Field

[0001] The invention relates to the technical field of silicon workpiece processing equipment, in particular to an automatic loading and unloading cutting machine. Background Art

[0002] Currently, during the processing of silicon rods, the silicon rods need to be placed horizontally on a processing platform, and then cut from top to bottom along the radial cross-section of the silicon rods by a silicon rod cutting mechanism to form cut sample silicon wafers or silicon rods of the required length.

[0003] The existing silicon rod cutting mechanism includes a support frame arranged on one side of the processing platform, and a cutting head that can slide up and down relative to the support frame is provided on the support frame, and the support frame and the cutting head are in a "7" shape. Therefore, since the cutting head is provided with multiple guide wheels to move the cut diamond wire, the weight of the cutting head causes the cutting head to tilt or shift, which in turn drives the diamond wire to shift. Therefore, when the silicon rod is cut, the cross-section of the cut silicon rod becomes elliptical, resulting in poor cutting effect.

[0004] Moreover, after the current cutting machine places the silicon rods on the support platform, it is necessary to manually adjust the level of the silicon rods, and then cut them after adjustment. After cutting, the silicon rods that meet the length need to be manually unloaded. This greatly increases labor costs, consumes manpower and time, and thus reduces the cutting efficiency of the silicon rods. Summary of the Invention

DETAILED DESCRIPTION

[0052] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation of is used as a reference. Figure 1 The two sides of the two vertical connecting beams 312 are respectively defined as "left and right", the side of the connecting seat 321 relative to the gantry frame 31 is defined as "upper", and the side of the main cutting guide wheel relative to the connecting seat 321 is defined as "front".

[0053] Reference Figure 1 As shown, an automatic loading and unloading cutting machine proposed in an embodiment of the present invention includes a silicon rod processing platform 1, a positioning mechanism 2, a cutting mechanism 3 and a feeding mechanism 7.

[0054] The top of the silicon ingot processing platform 1 is provided with a movable guide rail along its longitudinal direction (left-right length direction) and the same length as the silicon ingot processing platform 1. Moreover, the positioning mechanism 2 and the cutting mechanism 3 can slide left and right along the movable guide rail on the silicon ingot processing platform 1.

[0055] In this embodiment, two cutting mechanisms 3 are provided, one on each side of the positioning mechanism 2. Each cutting mechanism 3 includes a first cutting blade and a second cutting blade, respectively. The purpose of providing two cutting mechanisms 3 is to enable cutting of the silicon ingot a from both sides of the silicon ingot a, thereby improving cutting efficiency and ensuring that the positioning mechanism 2 is not affected.

[0056] In this embodiment, the positioning mechanism 2 is disposed between the first cutting blade and the second cutting blade. The positioning mechanism 2 includes a fixed support unit 21 and an adjustable support unit 22 that are spaced apart on the silicon rod processing platform 1 .

[0057] It should be noted that the purpose of the positioning mechanism 2 is that, since the forming process of silicon rod a is drawn, and the outer diameter of silicon rod a is not machined, both the diameter size and geometric shape of silicon rod a are subject to significant errors. That is, when forming the same silicon rod a, if the diameters of the circles containing the cross-sections at both ends of silicon rod a are not exactly the same during the drawing process, silicon rod a will be an irregularly tapered rod rather than a cylinder. This causes the line connecting the centers of the two end faces of the silicon rod a to be processed, which are placed in two V-shaped positioning grooves or two V-shaped positioning cavities spaced along the length of the processing platform, to tilt, resulting in a large tilt tolerance of the cut end face of silicon rod a and reduced processing quality.

[0058] Furthermore, both the fixed support unit 21 and the adjustable support unit 22 have support surfaces, which are respectively used to support both ends of the silicon rod a to be processed. The adjustable support unit 22 raises and lowers the first end of the silicon rod a to make the axis of the silicon rod a horizontal.

[0059] Furthermore, the adjustable support unit 22 comprises, arranged from bottom to top, a support base 221, a lifting assembly 222, and a support body 223. The support body 223 is used to support the silicon ingot a to be processed. The support base 221 is mounted on the silicon ingot processing platform 1. The lifting assembly 222 drives the support body 223 up and down relative to the support base 221, and the support body 223 is used to move the silicon ingot a up and down. The lifting of the lifting assembly 2222 adjusts the axis level of the silicon ingot a, facilitating quick adjustment.

[0060] Specifically, after the silicon rod a is placed horizontally on the positioning mechanism 2 and adjusted and fixed, the first and second cutting blades at both ends of the silicon rod a are used to cut the silicon rod a from both ends to form multiple silicon rod a units of the required length for subsequent processing.

[0061] Further, see Figure 6As shown, the lifting assembly 222 includes an adjustment motor 2221, a transmission structure and a lifting platform 2222. The adjustment motor 2221 is connected to the lifting platform 2222 through the transmission structure, and the lifting platform 2222 is connected to the supporting body 223.

[0062] Specifically, the adjustment motor 2221 can drive the transmission structure to drive the lifting platform 2222 to move up and down, and the lifting platform 2222 is used to drive the support body 223 to move up and down. The adjustment motor 2221 automatically controls the lifting of the left end of the first end of the silicon rod a to make adjustment more convenient.

[0063] Furthermore, the output end of the regulating motor 2221 is arranged horizontally, and the transmission structure includes a lead screw 2223, a lead screw nut 2224, a connecting plate 2225, two inclined blocks 2226, two rollers 2227 and two connecting brackets 2228.

[0064] It should be noted that the purpose of horizontally arranging the adjustment motor 2221 is to improve space utilization and make the structure compact.

[0065] Furthermore, the output end of the adjustment motor 2221 is fixedly connected to a screw 2223, which extends horizontally. The screw 2223 is threadedly connected to a screw nut 2224, the top of which is fixed to a connecting plate 2225. Two inclined blocks 2226 are fixedly mounted on the connecting plate 2225, spaced apart and inclined in the same direction. Two rollers 2227 are fixedly mounted on the lifting platform 2222 via connecting brackets 2228, respectively, and the two rollers 2227 are in contact with the two inclined blocks 2226.

[0066] The operating process is as follows: when adjustment is required, the adjustment motor 2221 is activated, which drives the lead screw 2223 to rotate. The lead screw 2223 then drives the lead screw nut 2224 to perform linear reciprocating motion along the axis (left-right direction) of the lead screw 2223. A connecting plate 2225 is connected to the lead screw nut 2224, allowing the connecting plate 2225 to move the two inclined blocks 2226 synchronously. The connecting plate 2225 and the two inclined blocks 2226 reciprocate horizontally, while the two rollers 2227 reciprocate on the inclined surfaces of the inclined blocks 2226, driving the lifting platform 2222 up and down.

[0067] Furthermore, the lifting assembly 222 also includes a plurality of guide structures 5 disposed between the lifting platform 2222 and the support base 221. The guide structures 5 are used to guide the lifting platform 2222 in its upward and downward movement. Specifically, the guide structures 5 are guide rods fixedly mounted on the support base 221 and guide sleeves disposed on the lifting platform 2222. The tops of the guide rods can extend upward into the guide sleeves, and the guide sleeves are provided with telescopic rods that plug into the guide rods to accommodate the lifting and lowering of the lifting platform 2222 and provide good guidance, thereby ensuring smoother lifting and lowering of the lifting platform 2222.

[0068] It should be noted that the structure of the fixed support unit 21 is similar to that of the adjustable support unit 22. There is no lifting component on the fixed support unit 21, and the rest of the structure is the same. Specifically, the fixed support unit 21 also includes a support base 221 and a support body 223. In other words, the fixed support unit 21 can also move left and right along the movable guide rail. The purpose is to install the two support bases 221 of the fixed support unit 21 and the adjustable support unit 22 on the moving straight movable guide rail on the silicon rod processing platform 1. By setting the traveling motor drive gear on the two support bases 221, the distance between the two support bases 21 can be automatically adjusted to adapt to the processing of silicon rods a of different lengths and prevent the silicon rod a from overturning.

[0069] Furthermore, the support body 223 includes a support plate 2231, and a "V"-shaped notch is provided on the top of the support plate 2231. That is, the support bodies 223 of the fixed support unit 21 and the adjustable support unit 22 are both "V"-shaped notches for supporting the silicon rod a. In other words, the double V-point centering positioning device facilitates the positioning of the silicon rod a, and the positioning effect is better. Moreover, positioning plates 2232 are provided on opposite sides of the "V"-shaped notch. The purpose of providing the positioning plate 2232 is to increase the contact area with the silicon rod a, improve the positioning accuracy, prevent the silicon rod a from moving, and achieve a better positioning effect.

[0070] In this embodiment, both the fixed support unit 21 and the adjustable support unit 22 include a clamping assembly 4 , which is used to fix both ends of the silicon rod a with its axis horizontal.

[0071] Furthermore, the clamping assembly 4 includes a clamping cylinder 41, a mounting bracket 42, and a rotating structure 43. The fixed end of the clamping cylinder 41 is disposed on the support base 221, and the extended end of the clamping cylinder 41 is fixedly connected to the mounting bracket 42. The mounting bracket 42 is used to mount the rotating structure 43. The clamping cylinder 41 can drive the rotating structure 43 to rise and fall through the mounting bracket 42 to compress the silicon ingot a to be processed.

[0072] The rotary structure 43 is vertically arranged on the mounting bracket 42 , and the rotary structure 43 can rotate around its own axis relative to the mounting bracket 42 .

[0073] Specifically, the rotary structure 43 includes a rotary cylinder, a connecting rod, and a rotary pressure plate. The rotary cylinder is fixedly mounted on the mounting bracket 42, and the output end of the rotary cylinder is fixedly connected to the connecting rod. The connecting rod is in a vertical position and is higher than the top of the silicon ingot a. The top of the connecting rod is fixedly connected to the rotary pressure plate.

[0074] It should be noted that the rotary cylinder can drive the connecting rod to rotate about its own axis. Before placing silicon rod a, the rotary cylinder controls the rotation of the connecting rod, which in turn drives the rotary clamping plate to rotate directly above silicon rod a, making way for silicon rod a. After the support unit 22 is adjusted, the rotary cylinder controls the connecting rod to rotate above silicon rod a. Then, the clamping cylinder 41 is activated, which drives the entire rotating structure downward through the mounting bracket 42, so that the rotary clamping plate can compress silicon rod a.

[0075] See also Figure 2-Figure 4 As shown, the cutting mechanism 3 comprises a gantry frame 31, a cutting head 32, and two detection assemblies 33. The gantry frame 31 is mounted on the silicon ingot processing platform 1 and is capable of linear reciprocating motion along the length of the platform 1. The cutting head 32 is mounted on the top of the gantry frame 31 and is used to cut the silicon ingots a on the platform 1. The two detection assemblies 33 are mounted on either side of the bottom of the gantry frame 31 to ensure synchronous movement of the two sides of the bottom of the gantry frame 31.

[0076] Furthermore, the gantry frame 31 includes two vertical connecting beams 312 arranged vertically and in parallel and a cross beam 311 for connecting the two vertical connecting beams 312 .

[0077] In this case, two vertical guide rails are provided on the opposite inner side walls of the two vertical connecting beams 312, so that the cutting head can perform vertical reciprocating motion up and down along the vertical guide rails, thereby driving the diamond wire b on the cutting guide wheel 324 on the cutting head to move toward or away from the silicon rod a, thereby cutting the silicon rod a on the silicon rod processing platform 1.

[0078] In this embodiment, the connecting seat 321 is disposed on the gantry frame 31 , and the gantry frame 31 can drive the cutting blade to perform linear reciprocating motion along the length direction of the silicon rod a.

[0079] It should be noted that before processing the silicon rod a, the silicon rod a is placed horizontally on the silicon rod processing platform 1. The silicon rod processing platform 1 has a positioning mechanism 2 for fixing and clamping the silicon rod a, so as to fix the silicon rod a to be processed and facilitate cutting.

[0080] Furthermore, in order to cooperate with the cutting process of the silicon rod a, movable guide rails are provided on both sides of the top of the silicon rod processing platform 1 along the axial direction of the silicon rod a. The movable guide rails cooperate with the linear movable guide rails on the traveling support at the bottom of the vertical connecting beam 312, so that the gantry frame 31 can perform linear reciprocating motion on the silicon rod processing platform 1, and perform equidistant cutting or slicing sampling and detection on the silicon rod a.

[0081] Furthermore, a magnetic grid sensor head is provided on the vertical connecting beam 312 , which can control the synchronization of the two vertical connecting beams 312 to achieve precise control of the walking displacement, thereby effectively ensuring the walking accuracy of the gantry frame 31 .

[0082] Furthermore, the cutting head 32 includes a connecting seat 321 , an adjusting assembly 322 , a driving assembly 323 and three cutting guide wheels 324 .

[0083] Furthermore, the connecting seat 321 is vertically arranged above the silicon rod processing platform 1 of the silicon rod a. Three cutting guide wheels 324 are arranged to form a triangular structure on the connecting seat 321 to allow the diamond wire b to be routed. Specifically, the diamond wire b is routed in a ring shape.

[0084] In this embodiment, the connecting seat 321 is a plate-shaped structural member, and a through slot is provided on the front side wall of the connecting seat 321. The purpose of the through slot is to cooperate with the connecting shaft of the driving component 323 of the cutting main wheel 4 to perform up and down lifting movements.

[0085] Furthermore, three cutting guide wheels 324 and an adjustment assembly 322 are respectively disposed on the front and rear sides of the connecting base 321. Specifically, the three cutting guide wheels 324 are disposed on the front side of the adjustment assembly 322, while the adjustment assembly 322 is disposed on the rear side. A drive assembly 323 is disposed on the same side (the rear side) as the adjustment assembly 322 and is fixedly mounted on the adjustment assembly 322. The output end of the drive assembly 323 is connected to any cutting guide wheel 324 to drive the cutting guide wheel 324 to rotate.

[0086] The adjustment component 322 drives the cutting guide wheel 324 to move closer to or away from the center of gravity of the triangle through the driving component 323 to adjust the tension of the diamond wire B. It should be noted that the center of gravity of the triangle is the intersection of the three midlines of the triangle.

[0087] Furthermore, the adjustment assembly 322 includes an adjustment power member and a movable slide 3221. Specifically, the adjustment power member includes a fixed motor 3222, a lead screw 3223 and a lead screw nut 3224.

[0088] Furthermore, an adjustable power member is fixedly mounted on the rear side of the connecting base 321, capable of driving the movable slide 3221 to perform linear reciprocating motion up and down along the guide rail 3222. Specifically, a drive assembly 323 is fixedly mounted on the movable slide 3221. It should be noted that the drive assembly 323 is a drive motor for the main cutting guide wheel and is a conventional drive component, which is not further defined herein.

[0089] Further, see Figure 2 As shown, the three cutting guide wheels 324 are arranged to form an isosceles triangle. The central axis of the isosceles triangle is vertical. This isosceles triangle structure ensures optimal routing of the diamond wire b, preventing interference with the cutting of the silicon rod a. Furthermore, the three cutting guide wheels 324 are positioned on the same vertical plane to ensure consistent cutting of the diamond wire b.

[0090] Furthermore, one cutting guide wheel 324 is at the top and two cutting guide wheels 324 are at the bottom, and the three together form a triangular structure. The cutting guide wheel 324 at the top is the main cutting guide wheel, and the cutting guide wheels 324 on both sides of the central axis are both passing wheels. The driving assembly 323 is connected to the main cutting guide wheel, and the through groove is opened at the position corresponding to the main cutting guide wheel in the vertical direction. The purpose of arranging the main cutting guide wheel at the top is to prevent the cutting fluid at the bottom of the silicon rod processing platform 1 from splashing onto the driving assembly 323 and the adjustment body 2 when the driving assembly 323 and the adjustment body 2 are cutting the diamond wire b, thereby protecting the driving components of the driving assembly 323 and the adjustment body 2.

[0091] It should be noted that the main cutting guide wheel of the present invention not only drives the diamond wire b and the two passing wheels to rotate, but also cooperates with the adjustment body 2 to adjust the tension, thus saving a passing wheel.

[0092] In addition, this embodiment eliminates the original heavy hammer tension structure and adopts the driving component 323 to drive the main cutting guide wheel to move up and down, and then the main cutting guide wheel tightens and relaxes the annular diamond wire b to achieve the purpose of controlling the tension of the diamond wire b.

[0093] Furthermore, the diameter of the main cutting guide wheel is larger than the diameter of the two passing wheels, which can increase the diameter of the main cutting guide wheel, thereby reducing the overall rotational inertia, increasing the cutting line speed, improving the cutting efficiency, and reducing the risk of wire breakage.

[0094] Furthermore, the diameter of the main cutting guide wheel is in the range of 300 mm to 400 mm. Preferably, a main cutting guide wheel with a diameter of 350 mm is used, which can enable the cutting speed of the diamond wire b to reach 80 m / s for high-speed cutting.

[0095] It should be noted that the fixed motor 3222 is fixedly mounted on the support. The output end of the fixed motor 3222 is connected to the lead screw 3223. The lead screw nut 3224 is screwed onto the outside of the lead screw 3223, and the lead screw nut 3224 is fixedly connected to the movable slide 3221. The through slot is provided with guide rails 3222 at both ends of the side near the fixed motor 3222 for the movable slide 3221 to slide. By directly fixing the fixed motor 3222 to the rear sidewall of the connecting base 321, the structure is simple and easy to operate. The fixed motor 3222 can receive signals from the processor and control the rotation of the fixed motor 3222 accordingly, thereby controlling the position of the movable slide 3221 and, further, the tension of the diamond wire b on the cutting guide wheel 324. Specifically, when the movable slide 3221 drives the drive assembly 323 and the main cutting guide wheel upward, the tension of the diamond wire b increases, tightening the loose diamond wire b, thereby improving the cutting effect.

[0096] Furthermore, the two pulleys are removably mounted to the connecting base 321 via a pulley mounting plate 8. The connecting base 321 is provided with a horizontally arranged elongated hole, along which the pulley mounting plate 8 can slide and secure. This facilitates installation and removal of the pulleys, as well as subsequent maintenance. The elongated hole allows for easy adjustment of the spacing between the two pulleys. The spacing between the two driven pulleys is adjustable to accommodate processing of silicon rods of varying diameters.

[0097] Furthermore, a tension sensor 6 is provided on one of the pulleys to detect the tension of the diamond wire b and transmit the tension information to the processor. The processor controls the movement of the adjustment component 322 based on the tension information to adjust the tension of the diamond wire b. This allows for automatic tension adjustment without manual intervention, saving time and improving cutting efficiency.

[0098] In comparison, the original weight structure couldn't automatically adjust tension, requiring manual removal and replacement of the weight to adjust tension. This new structure automatically adjusts tension based on tension sensing, maintaining a small, stable bow during ingot cutting and improving cutting quality.

[0099] The present invention provides an automatic loading and unloading cutting machine, in which a driving assembly 323 directly drives any one of the cutting guide wheels 324 to act as the main cutting guide wheel, driving the diamond wire b and the other two cutting guide wheels 324 to rotate together as the passing wheels. The direct drive method has good rotation consistency. In addition, the main cutting guide wheel and the driving assembly 323 are fixedly connected to the adjustment assembly 322 as a whole. The adjustment assembly 322 drives the main cutting guide wheel and the driving assembly 323 to slide along the longitudinal direction of the slide groove, so that the cutting guide wheel 324 connected to the driving assembly 323 approaches or moves away from the center of gravity of the triangle, thereby adjusting the tension of the diamond wire b. Compared with the existing gravity hammer adjustment, the tension adjustment of the adjustment assembly 322 is convenient, saving tension adjustment time and improving the cutting efficiency of the silicon rod a. Moreover, by arranging the cutting head 32 on the gantry frame 31, the stability of the cutting head 32 can be ensured and the cutting head 32 can be prevented from tilting. Moreover, detection components 33 are provided on both sides of the bottom of the gantry frame 31. The detection components 33 can ensure that both sides of the gantry frame 31 move synchronously along the silicon rod processing platform 1 to ensure that the diamond wire b on the cutting head 32 is in a straight line, thereby preventing the cut surface from tilting. At the same time, the positioning accuracy of the gantry frame 31 is improved. At the same time, the positioning accuracy of the gantry frame 31 is improved. Furthermore, through the mutual cooperation of the positioning mechanism 2, the silicon rod platform 1, the cutting mechanism 3 and the unloading mechanism 7, the function of automatic loading and unloading is completed. Compared with the existing cutting machine, a fully automated multifunctional silicon rod cutting is realized.

[0100] In this embodiment, the unloading mechanism 7 is arranged directly below the cutting mechanism 3 , that is, two unloading mechanisms 7 are also provided, which can unload the silicon rods a from both sides, thereby improving the unloading efficiency.

[0101] The unloading mechanism 7 includes two sampling devices 71 and a tail unloading device 72 that are arranged opposite to each other.

[0102] Furthermore, the sampling device 71 is arranged on the silicon rod processing platform 1 and moves along the silicon rod processing platform 1 toward or away from the head of the silicon rod or the end face of the sample i. The sampling device 71 can support the head of the silicon rod or support and adsorb the sample i, cut the head of the silicon rod and the sample i, and transport the cut silicon rod head or sample i to the first unloading position and the second unloading position respectively.

[0103] It should be noted that the cutting and blanking of sample i does not require manual labor, while ensuring the quality of sample i and accurate blanking.

[0104] It should be noted that the first unloading position and the second unloading position are located in two different directions. The first unloading position is at the top of the left end of the silicon rod processing platform 1. The second unloading position is at the rear of the silicon rod processing platform 1, see Figure 7 shown.

[0105] Among them, see Figure 7-10 As shown, the sampling device 71 includes a moving component 711, a supporting component 712 for cutting off the special-shaped head of the silicon rod, and a rotating component 713.

[0106] In this embodiment, the moving assembly 711 is disposed on the silicon rod processing platform 1 , and the moving assembly 711 can slide relatively along the length direction of the silicon rod processing platform 1 .

[0107] The support component 712 is arranged on the moving component 711, and the support component 712 slides relative to the moving component 711 along the length direction of the moving component 711 to approach the head of the silicon rod or the end face of the sample i. The support component 712 can support the head of the silicon rod or support and adsorb the sample i, and cut the head of the silicon rod or the sample i through the cutting head. After cutting, the support component 712 slides along the length direction of the moving component 711 to move away from the head of the silicon rod, so that the head of the silicon rod falls on the moving component 711.

[0108] The moving assembly 711 can drive the head of the silicon rod to the first unloading position for unloading the head.

[0109] Alternatively, support assembly 712 can simultaneously move sample i away from the end face of the silicon ingot. Rotating assembly 713 is connected to support assembly 712 and moving assembly 711. Rotating assembly 713 can rotate support assembly 712, which has been attached to sample i, to a second unloading position to unload sample i. After unloading sample i, the silicon ingot molding result is tested based on sample i.

[0110] Next, the moving assembly 711 can drive the special-shaped head to the unloading position.

[0111] It should be noted that the unloading position is located on the left side of the silicon rod support platform a. A robot is installed directly above the unloading position, and then the unloading clamp robot takes the unloading material to the conveyor roller, completing the unloading fully automatically without manual labor.

[0112] Furthermore, the support assembly 712 includes a support adsorption structure 7121 and a first auxiliary support assembly 7122. The support adsorption structure 7121 is connected to the moving assembly 711 to support one end of the special-shaped head.

[0113] Further, see Figure 5-Figure 7 As shown, the support and adsorption structure 7121 includes a support body 71211, a head support sleeve 1212, and multiple sample suction cups 71213. One end surface of the support body 71211 is connected to the rotating assembly 713, and the other end surface of the support body 71211 is connected to the head support sleeve 71212, which can support the head of the silicon rod.

[0114] Multiple sample suction cups 71213 are arranged on one end face of the support body 71211 close to the head support sleeve 71212, and multiple sample suction cups 71213 are arranged at circumferential intervals along the end face of the support body 71211, and the sample suction cups 71213 protrude from one end of the head support sleeve 71212. The sample suction cups 71213 can be pressed against the sample i to absorb the sample i.

[0115] See also Figure 5 As shown, the support body 71211 has a support base, which is fixed to the screw nut of the moving assembly 711 and slides left and right with the screw nut. The support body 71211 is connected to the head support sleeve 71212 through the support connecting rod 132, and the bottom of the head support sleeve 71212 is higher than the top of the first auxiliary support assembly 7122. The head support sleeve 71212 has a tapered plug hole for inserting the tapered head, which can better cooperate with the special-shaped head for support and positioning. In addition, the purpose of the bottom of the head support sleeve 71212 being higher than the top of the first auxiliary support assembly 7122 is to be able to support the special-shaped head from both the end and the bottom, thereby ensuring the support effect.

[0116] It should be noted that before processing, the axis of the head support sleeve 71212 and the axis of the silicon rod need to be ensured to be on the same horizontal line, which can be achieved by adjusting the horizontal position of the support and positioning device where the silicon rod is located.

[0117] In this embodiment, the rotating assembly 713 includes a rotating cylinder 7131 and a supporting connecting rod 7132. The rotating cylinder 7131 is connected to the moving assembly 711 through the supporting body 71211. The output end of the rotating cylinder 7131 is fixedly connected to the supporting connecting rod 7132. The rotating cylinder 7131 can rotate the supporting connecting rod 7132 along the axis of its output shaft to drive the head support sleeve 71212 to rotate. The purpose of adding the rotating cylinder 7131 is to rotate the supporting body 71211 with the sample i adsorbed 90° counterclockwise by the rotating cylinder 7131 during unloading, and the supporting adsorption structure 7121 is rotated and laid down along its axis as a whole to rotate the sample i to the second unloading position. When sampling is not required, that is, when the head needs to be unloaded, the purpose of the setting of the rotating cylinder 7131 is to make way for the manipulator at the first unloading position when unloading the special-shaped head.

[0118] See also Figure 5 The first auxiliary support component 7122 is fixedly connected to the support adsorption structure 7121 to support the bottom end of the special-shaped head.

[0119] Furthermore, the first auxiliary support assembly 7122 includes a bottom support block 71221 and an auxiliary support cylinder 71222. The auxiliary support cylinder 71222 is connected to the bottom support block 71221 and can drive the bottom support block 71221 to move upward and downward. The bottom support block 71221 can support the bottom end of the silicon rod head. The auxiliary support cylinder 71222 can also drive the connection plate 71227 to move upward and downward. Of course, other power components capable of controlling the movement of the connection plate 71227 can also be used.

[0120] It should be noted that the left and right movement of the blanking device on the silicon rod support platform a is achieved by driving a walking motor so as to move closer to or away from the special-shaped head in a general direction. After the entire blanking device approaches the special-shaped head, the supporting adsorption structure 7121 and the first auxiliary support component 7122 are further driven by the moving component 711 to approach the special-shaped head along the slide rail of the moving component 711, so that the special-shaped head is just inserted into the conical plug-in hole, and the bottom support block 71221 of the first auxiliary support component 7122 is against the special-shaped head to form a good support. In addition, the first auxiliary support component 7122 can also move up and down under the support of the auxiliary support cylinder 71222 to support special-shaped heads of different shapes. It should be noted that the moving component 711 can be any existing structural component that drives lateral movement, and no further details will be given here.

[0121] Furthermore, the first auxiliary support assembly 7122 also includes an adaptive structural member. The adaptive structural member can generate elastic force in the lateral direction to make the bottom support block 71221 abut against the bottom end of the special-shaped head and fix the bottom support block 71221. By setting the adaptive structural member, adaptive support for special-shaped heads of different lengths and different taper angles can be achieved. At the same time, it can prevent the special-shaped head from micro-moving during the cutting process and reduce the occurrence of edge collapse. Manual operation is eliminated. After cutting is completed, the servo motor of the mobile assembly 711 drives it to the unloading position, and finally the unloading robot clamps the unloading material.

[0122] Furthermore, the adaptive structural component includes an adaptive guide rod 71223 , a spring 71224 , a guide rod restrainer 71225 and a support block mounting seat 71226 .

[0123] In this embodiment, a connecting plate 71227 is connected to the auxiliary support cylinder 71222. An adaptive guide rod 71223 is horizontally mounted on the connecting plate 71227. One end of the adaptive guide rod 71223, located near the bottom support block 71221, is fixedly connected to a support block mounting seat 71226. A spring 71224 is sleeved around the exterior of the adaptive guide rod 71223. The ends of the spring 71224 respectively abut against the support block mounting seat 71226 and the guide rod restrainer 71225. The support block mounting seat 71226 is used to mount the bottom support block 71221. The bottom support block 71221 can be lifted and lowered under the action of the lifting cylinder of the auxiliary support cylinder 71222, and can also move horizontally under the action of the spring 71224 and the adaptive guide rod 71223. After ensuring that the bottom support block 71221 is in contact with the end of the silicon rod and the bottom inclined surface, the adaptive guide rod 71223 is locked and fixed under the action of the guide rod restrainer 71225, thereby improving the positioning support effect.

[0124] Furthermore, the tail unloading device 72 can move along the silicon rod processing platform 1 toward or away from the tail of the silicon rod, so that the tail unloading device 72 supports the tail of the silicon rod and transports the cut tail to the third unloading position.
