Description

Technical Field

[0001] The present invention relates to the technical field of silicon workpiece processing equipment, and in particular to a sampling device for silicon rods and a feeding system thereof. Background Art

[0002] The formation of silicon rods includes the growth of silicon rods, that is, the single crystal silicon is in a molten state inside the single crystal, and the molten single crystal silicon is pulled and cooled by a pulling head to form a silicon rod.

[0003] Since the forming process of the silicon rod is drawn, it is very easy for a conical shape to appear during the drawing process, especially at the front end of the silicon rod, and the conical head is named the head of the silicon rod. A wavy end face is very easy to appear at the end of the silicon rod, and the wavy tail is named the special-shaped tail of the silicon rod. However, in the later truncation process of the silicon rod, it is necessary to remove both the head and tail of the silicon rod to meet the needs of subsequent truncation of the silicon rod into silicon rods of different lengths, which is convenient for subsequent processing. After removing the head and tail, in order to ensure whether the quality of the silicon rod meets the standards before truncation, it is necessary to cut a circular sample along the cross section of the silicon rod using a cutting head, and remove the test sample to see whether it meets the processing requirements.

[0004] However, at present, the head and tail of the silicon rod are generally removed by manually straightening the end face of the special-shaped tail to cooperate with the cutting of the tail, which has a poor support effect. Moreover, manual sampling is also adopted for taking samples of the silicon rod. As a result, manual sampling will also affect the detection accuracy of the samples, thereby reducing the cutting efficiency and affecting the detection effect. Summary of the Invention

DETAILED DESCRIPTION

[0061] 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 is referenced. Figure 1 The positions of the first cutting head d, the second cutting head e, the first supporting device f and the second supporting device g relative to the processing platform a are defined as "upper"; the first cutting head d and the second cutting head e are arranged on the "left and right" sides relative to the processing platform a; the side perpendicular to the paper surface facing inward is defined as "back".

[0062] Reference Figure 1As shown, a cutting production line proposed in an embodiment of the present invention includes a blanking device for cutting off the special-shaped tail of a silicon rod, a processing platform a, a supporting and positioning device, a first cutting head d and a second cutting head e.

[0063] The top of processing platform a is equipped with a movable guide rail extending longitudinally (left-right) along its entire length. The unloading device, support and positioning device, first cutting blade d, and second cutting blade e used to cut off the irregularly shaped tail of the silicon ingot can all slide left and right along the movable guide rail on processing platform a.

[0064] The support and positioning device is positioned between the first cutting head d and the second cutting head e. The bottoms of the first and second support devices f and g of the centering system, as well as the bottoms of the first and second cutting heads d and e, are all capable of moving along movable guide rails. Specifically, after the silicon rod is horizontally placed on the support and positioning device and adjusted and secured, the first and second cutting heads d and e, which can move horizontally left and right along the movable guide rails, cut the silicon rod from each end to form multiple silicon rod units of the required length for subsequent processing.

[0065] It should be noted that before the two cutting heads start cutting, the centering positioning system needs to be determined so that the first cutting head d and the second cutting head e can make way for each other to cooperate with the cutting work.

[0066] In addition, before being cut, since the entire silicon rod is drawn, a conical, irregularly shaped head portion b and a wavy, irregularly shaped tail portion h are formed during the drawing process, particularly at the starting end, or tail portion, of the silicon rod. Therefore, the sampling device 1 is required to cooperate with the cutting head c on the second cutting blade d to cut the irregularly shaped head portion b and to unload and transport the cut irregularly shaped head portion b to the first unloading position. The sampling device 1 can also cooperate with the cutting head c on the second cutting blade d to cut the sample i and to unload and transport the cut sample i to the second unloading position. The tail unloading device 2 cooperates with the cutting head c on the first cutting blade e to cut the irregularly shaped tail portion h and to unload and transport the irregularly shaped tail h to the unloading position.

[0067] Among them, see Figures 1-10 As shown, a sampling device for cutting silicon rods and a feeding system thereof include two sampling devices 1 and a tail feeding device 2 arranged opposite to each other.

[0068] Furthermore, the sampling device 1 is arranged on the processing platform a and moves along the processing platform a toward or away from the head of the silicon rod or the end face of the sample i. The sampling device 1 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 head of the silicon rod or the sample i to the first unloading position and the second unloading position respectively.

[0069] 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.

[0070] 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 processing platform a. The second unloading position is at the rear of the processing platform a. Figure 7 shown.

[0071] Among them, see Figure 2-Figure 5 As shown, the sampling device 1 includes a first moving component 11, a first supporting component 12 for cutting off the special-shaped head of the silicon rod, and a rotating component 13.

[0072] In this embodiment, the first moving assembly 11 is disposed on the processing platform a, and the first moving assembly 11 can slide relatively along the length direction of the processing platform a.

[0073] The first supporting assembly 12 is arranged on the first movable assembly 11, and the first supporting assembly 12 slides relative to the first movable assembly 11 along the length direction of the first movable assembly 11 to approach the head of the silicon rod or the end face of the sample i. The first supporting assembly 12 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 first supporting assembly 12 slides along the length direction of the first movable assembly 11 to move away from the head of the silicon rod, so that the head of the silicon rod falls on the first movable assembly 11.

[0074] The first moving assembly 11 can drive the head of the silicon rod to be transported to the first unloading position for unloading the head.

[0075] Alternatively, the first support assembly 12 can simultaneously move the sample i away from the end face of the silicon ingot. The rotation assembly 13 is connected to the first support assembly 12 and the first moving assembly 11. The rotation assembly 13 can rotate the first support assembly 12, which has attracted the sample i, to the second unloading position to unload the sample i. After unloading the sample i, the silicon ingot forming result is tested based on the sample i.

[0076] Next, the first moving assembly 11 can drive the special-shaped head b to be transported to the unloading position.

[0077] 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.

[0078] Furthermore, the first supporting assembly 12 includes a supporting adsorption structure 121 and a first auxiliary supporting assembly 122. The supporting adsorption structure 121 is connected to the first moving assembly 11 to support one end of the special-shaped head b.

[0079] Further, see Figure 5-Figure 7 As shown, the support and adsorption structure 121 includes a support body 1211, a head support sleeve 1212, and a plurality of sample suction cups 1213. One end surface of the support body 1211 is connected to the rotating assembly 13, and the other end surface of the support body 1211 is connected to the head support sleeve 1212, which can support the head of the silicon rod.

[0080] Multiple sample suction cups 1213 are arranged on one end face of the support body 1211 close to the head support sleeve 1212, and multiple sample suction cups 1213 are arranged at circumferential intervals along the end face of the support body 1211, and the sample suction cups 1213 protrude from one end of the head support sleeve 1212. The sample suction cups 1213 can be pressed against the sample i to absorb the sample i.

[0081] See also Figure 5 As shown, the support body 1211 has a support base 12111, which is fixed to the screw nut of the first movable assembly 11 and slides left and right with the screw nut. The support body 1211 is connected to the head support sleeve 1212 via a support connecting rod 132, and the bottom of the head support sleeve 1212 is higher than the top of the first auxiliary support assembly 122. The head support sleeve 1212 has a tapered insertion hole for inserting a tapered head, which can better cooperate with the special-shaped head b for support and positioning. The purpose of the bottom of the head support sleeve 1212 being higher than the top of the first auxiliary support assembly 122 is to provide support from both the end and the bottom of the special-shaped head b, ensuring the support effect.

[0082] It should be noted that before processing, the axis of the head support sleeve 1212 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.

[0083] In this embodiment, the rotating assembly 13 includes a rotating cylinder 131 and a supporting connecting rod 132. The rotating cylinder 131 is connected to the first moving assembly 11 through the supporting body 1211. The output end of the rotating cylinder 131 is fixedly connected to the supporting connecting rod 132, and the rotating cylinder 131 can rotate the supporting connecting rod 132 along the axis of its output shaft to drive the head support sleeve 1212 to rotate. The purpose of adding the rotating cylinder 131 is to rotate the supporting body 1211 with the sample i adsorbed 90° counterclockwise by the rotating cylinder 131 during unloading, and the supporting adsorption structure 121 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 setting the rotating cylinder 131 is to make way for the manipulator at the first unloading position when unloading the special-shaped head b.

[0084] See also Figure 5 The first auxiliary support component 122 is fixedly connected to the support adsorption structure 121 to support the bottom end of the special-shaped head b.

[0085] Furthermore, the first auxiliary support assembly 122 includes a bottom support block 1221 and an auxiliary support cylinder 1222. The auxiliary support cylinder 1222 is connected to the bottom support block 1221 and can drive the bottom support block 1221 to move upward and downward. The bottom support block 1221 can support the bottom end of the silicon rod head. The auxiliary support cylinder 1222 can also drive the connection plate 1227 to move upward and downward. Of course, other power components capable of controlling the movement of the connection plate 1227 can also be used.

[0086] 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 travel motor, thereby generally approaching or moving away from the irregular head b. After the entire blanking device approaches the irregular head b, the first moving assembly 11 drives the supporting adsorption structure 121 and the first auxiliary support assembly 122 to further approach the irregular head b along the slide rails of the first moving assembly 11, so that the irregular head b fits neatly into the tapered socket, and the bottom support block 1221 of the first auxiliary support assembly 122 abuts against the irregular head b, providing good support. In addition, the first auxiliary support assembly 122 can also move up and down, supported by the auxiliary support cylinder 1222, to support irregular heads b of different shapes.

[0087] Furthermore, the first auxiliary support assembly 122 also includes an adaptive structural member. The adaptive structural member can generate elastic force in the lateral direction to make the bottom support block 1221 abut against the bottom end of the special-shaped head b and fix the bottom support block 1221. By setting the adaptive structural member, adaptive support can be achieved for special-shaped heads b of different lengths and different taper angles. At the same time, it can prevent the special-shaped head b from producing micro-movements during the cutting process and reduce the occurrence of edge collapse. Manual operation is eliminated. After cutting is completed, the servo motor of the first moving assembly 11 drives it to the unloading position, and finally the unloading robot clamps the unloading material.

[0088] Furthermore, the adaptive structural component includes an adaptive guide rod 1223 , a spring 1224 , a guide rod restrainer 1225 and a support block mounting seat 1226 .

[0089] In this embodiment, a connecting plate 1227 is connected to the auxiliary support cylinder 1222. An adaptive guide rod 1223 is horizontally mounted on the connecting plate 1227. One end of the adaptive guide rod 1223, located near the bottom support block 1221, is fixedly connected to a support block mounting seat 1226. A spring 1224 is sleeved around the exterior of the adaptive guide rod 1223, with both ends of the spring 1224 abutting against the support block mounting seat 1226 and a guide rod retainer 1225, respectively. The support block mounting seat 1226 is used to mount the bottom support block 1221. The bottom support block 1221 can be raised and lowered by the lifting cylinder of the auxiliary support cylinder 1222, and can also be moved horizontally by the spring 1224 and the adaptive guide rod 1223. After ensuring contact between the bottom support block 1221 and the end and bottom slope of the silicon rod, the guide rod retainer 1225 locks the adaptive guide rod 1223, enhancing the positioning and support effectiveness.

[0090] Furthermore, the tail unloading device 2 can move along the processing platform a toward or away from the tail of the silicon rod, so that the tail unloading device 2 supports the tail of the silicon rod and transports the cut tail to the third unloading position.

[0091] See also Figure 1 and Figure 4 As shown, the first moving component 11 is disposed on the processing platform a, and the first moving component 11 can slide relatively along the length direction of the processing platform a to approach or move away from the special-shaped tail h.

[0092] Furthermore, the first moving assembly 11 includes a moving support 111 , a blanking support mechanism and a moving driving member 112 .

[0093] It should be noted that the movable support 111 is slidably mounted on the processing platform a. Figure 4The movable support 111 drives the first movable component 11 of the whole to slide left and right relative to the movable guide rail on the processing platform a through the travel motor, and drives the whole blanking device to slide left and right relative to the processing platform a along its length direction to cooperate with the blanking of the special-shaped tail h.

[0094] See also Figure 4 As shown, the unloading support mechanism includes two brackets 113 symmetrically positioned relative to the front and rear ends of the silicon rod. These brackets 113 are connected to the front and rear ends of the movable support 111, respectively. Each bracket 113 includes a support slope, and the two brackets 113 form a "V"-shaped support groove. This facilitates the support and unloading of the entire silicon rod. Even with the support and positioning device supporting the entire silicon rod, if the silicon rod needs to be cut, a portion of the silicon rod must be placed on the brackets 113 on the unloading support mechanism before being cut using the cutting head c.

[0095] In this embodiment, the mobile driving member 112 is disposed between the two brackets 113 and is fixedly connected to the mobile support 111. The mobile driving member 112 can drive the support body to slide along its length. Alternatively, the second mobile assembly 21 can drive the second support assembly 22 to slide along its length.

[0096] Specifically, the mobile drive component 112 includes a mobile slide, a servo motor, a lead screw, and a lead screw nut. The mobile slide is fixedly mounted on the mobile support 111. The output shaft of the mobile motor is axially and horizontally mounted at one end of the mobile slide. The output end of the mobile motor is fixedly connected to the lead screw. The outer wall of the lead screw is threadedly connected to the lead screw nut. The lead screw nut can slide horizontally along the length of the lead screw. The lead screw nut is connected to the support body 1211, and the support body 1211 can move along the slide rail on the mobile slide. The mobile drive component 112 has a simple structure and low cost.

[0097] Furthermore, the bracket 113 includes a bracket body 1131 and a plurality of buffer cylinders 1132. The bracket body 1131 has an inwardly inclined end surface, and the plurality of buffer cylinders 1132 are spaced apart on the inclined end surface.

[0098] Furthermore, the outer peripheral side wall of the extended end of the buffer cylinder 1132 is sleeved with an elastic protective sleeve 1133. It can protect the cylinder body and prevent cutting fluid from entering the cylinder during cutting, which will affect the life of the cylinder.

[0099] In this embodiment, the support body 1211 is arranged on the first movable component 11, and the support body 1211 slides relative to the first movable component 11 along the length direction of the first movable component 11 to approach the special-shaped head b. The support body 1211 supports the special-shaped head b, and the special-shaped head b of the special-shaped head b is cut by the cutting head c. After cutting, the support body 1211 slides along the length direction (left and right direction) of the first movable component 11 to move away from the special-shaped head b, and the special-shaped head b falls on the first movable component 11.

[0100] Next, the first moving assembly 11 can drive the special-shaped head b to be transported to the unloading position.

[0101] It should be noted that the unloading position is located on the left side of the processing platform a. A robot is set just above the unloading position, and then the unloading clamp robot takes the unloading material to the conveyor roller, completing the fully automatic unloading without manual labor.

[0102] Furthermore, the tail unloading device 2 includes a second moving assembly 21 , a second supporting assembly 22 , and a rotating structural member 14 having the same function as the rotating assembly 13 .

[0103] The second moving assembly 21 is disposed on the processing platform a, and the second moving assembly 21 can slide relatively along the length direction of the processing platform a.

[0104] See also Figure 8-10 As shown, the second supporting assembly 22 is arranged on the second movable assembly 21, and the second supporting assembly 22 slides relative to the second movable assembly 21 along the length direction of the second movable assembly 21 to approach the tail of the silicon rod. The second supporting assembly 22 can absorb and support the tail of the silicon rod, and cut the tail of the silicon rod through the cutting head. After cutting, the second supporting assembly 22 slides along the length direction of the second movable assembly 21 to move away from the tail of the silicon rod, so that the tail of the silicon rod falls on the second movable assembly 21.

[0105] The second moving assembly 21 can drive the tail of the silicon rod to be transported to the third unloading position for unloading the tail of the silicon rod.

[0106] See also Figure 8 As shown, the second support assembly 22 is connected to the rotating structure, which is connected to the second movable assembly 21. The second movable assembly 21 can move with the left and right lateral movement of the second support assembly 22. The second movable assembly 21 can drive the rotating structure to drive the second support assembly 22 to support the end surface of the special-shaped tail h.

[0107] Furthermore, the second support assembly 22 includes a support cylinder 221 and a plurality of adsorption structures 222 .

[0108] It should be noted that, see Figure 11As shown, the support cylinder 221 has a hollow chamber, and a partition plate 2229 is provided in the middle position of the hollow chamber to divide the hollow chamber into two chambers, and one end of the adsorption structure 222 is provided in the chamber close to the left side of the hollow chamber, and a plurality of connecting pipes are provided in the chamber on the right side for connecting with the external air pump and the adsorption structure 222, that is, providing an accommodation space for the connecting pipes.

[0109] Furthermore, the right side wall end surface of the support cylinder 221 is connected to the rotating structure. One end (right end) of each adsorption structure 222 is disposed in the support cylinder 221, and the other end (left end) of each adsorption structure 222 extends horizontally and protrudes from the support cylinder 221.

[0110] It should be noted that before processing, the axis of the support cylinder 221 and the axis of the silicon rod must be ensured to be on the same horizontal line, which can be achieved by adjusting the horizontal position of the support positioning device where the silicon rod is located to ensure a better support effect.

[0111] In this embodiment, each adsorption structure 222 has elasticity and can abut against the end surface of the special-shaped tail h one by one (see Figure 10 As shown in FIG, each adsorption structure 222 can be adsorbed and fixed on the end surface of the special-shaped tail h. It can adapt to the special-shaped tail h of different shapes, thereby achieving a large area of ​​contact with the special-shaped tail h and forming a good support.

[0112] See also Figure 11 As shown, the suction structure 222 includes an adjustment guide rod 2221, a locking mechanism, and a tail suction cup 2222. The adjustment guide rod 2221 includes a fixed end and an extended end. The fixed end is disposed in the inner cavity of the support cylinder 221, and the extended end extends horizontally and is fixedly connected to the tail suction cup 2222. The extended end can drive the tail suction cup 2222 to reciprocate along its axis relative to the fixed end, so that the tail suction cup 2222 and the special-shaped tail h are abutted.

[0113] It should be noted that an auxiliary elastic protective sleeve 2228 is provided on the outer side of the supporting cylinder 221 at the extended end of the adjusting guide rod 2221 , which can play a role in shock absorption and buffering, as well as protection for the adjusting guide rod 2221 .

[0114] In this embodiment, the locking mechanism is connected to the protruding end of the adjusting guide rod 2221 to lock the protruding end of the adjusting guide rod 2221 .

[0115] Specifically, the locking assembly includes a locking driver 2223, a transmission member, and a plurality of locking wedges 2224. The locking driver 2223 is fixedly mounted within the support cylinder 221 and is connected to the transmission member, which is in turn fixedly connected to the locking wedges 2224. The locking driver 2223 drives the transmission member to move the plurality of locking wedges 2224 toward their corresponding adjustment guide rods 2221, thereby locking the adjustment guide rods 2221.

[0116] Furthermore, the transmission member includes two locking movable guide rails 2225 arranged in parallel and two locking arms arranged between the two locking movable guide rails 2225, and the two locking arms are arranged in a centrally symmetrical manner relative to the supporting cylinder 221.

[0117] See also Figure 12 As shown, each locking arm includes a connecting rod 2226 and a locking head 2227. The connecting rod 2226 is disposed between the two locking movable guide rails 2225, and the ends of the connecting rod 2226 are integrally formed with locking wedges 2224 to form a first locking portion and a second locking portion, respectively. The locking wedge 2224 is disposed at the bottom or top of the locking head 2227 to form a third locking portion.

[0118] Furthermore, the tail suction cup 2222 can be connected to an external air extraction assembly via a pipeline, so that a negative pressure state is formed between the tail suction cup 2222 and the special-shaped tail h. This can better absorb the special-shaped tail h. When the two need to be separated, the external air pump is stopped, and the tail suction cup 2222 releases the negative pressure state with the special-shaped tail h, allowing the support body 1211 and the special-shaped tail h to separate.

[0119] In addition, the rotating structure can drive the second support assembly 22 to rotate so that the second support assembly 22 is in a vertical state or a horizontal state. In order to cooperate with the work of the blanking device, the support body 1211 is made to give way.

[0120] In this embodiment, the rotating structure 14 includes a second rotating cylinder 141 and a swing arm 142. The output end of the second rotating cylinder 141 is arranged horizontally and connected to the bottom of one side wall of the swing arm 142. The top of the other side wall of the swing arm 142 is fixedly connected to the support cylinder 221. The purpose of adding the second rotating cylinder 141 is to rotate the supporting adsorption structure 121 along its axis and lay it down (i.e. Figure 9 (Rotate 90° counterclockwise) to make way for the robot at the unloading position.

[0121] Furthermore, the second support assembly 22 also includes a second auxiliary support assembly 223. The second auxiliary support assembly 223 is arranged on the side of the second support assembly 22 close to the adsorption structure 222, and the second auxiliary support assembly 223 can support the bottom of the special-shaped tail h. Specifically, the second auxiliary support assembly 223 includes an auxiliary support cylinder 2231 and an auxiliary support adsorption structure 2232. The auxiliary support cylinder 2231 drives the auxiliary support adsorption structure 2232 to rise and fall to match the bottom support rod of the special-shaped tail h, and can adapt to special-shaped tails h of different heights. In addition, the structure of the auxiliary support adsorption structure 2232 is the same as the specific structure of the adsorption structure 222, except that the direction of adsorption and the position of adsorption are different. That is, the special-shaped tail h is further supported by the second auxiliary support assembly 223, thereby reducing the occurrence of edge collapse during cutting.

[0122] It should be noted that the left and right movement of the blanking device on the processing platform a is achieved by the travel motor, so that it moves in the general direction toward or away from the special-shaped tail h. When the entire blanking device approaches the special-shaped tail h, the mobile driver 112 drives the second support assembly 22, the suction structure 222, and the second auxiliary support assembly 223 toward the special-shaped tail h. The slide rail of the movable drive member 112 is then moved closer to the shaped tail h, so that the shaped tail h just contacts the tail suction cup 2222 of the adsorption structure 222. At this point, the tail suction cup 2222 completely abuts the shaped tail h through its own elasticity and adaptiveness. The adjustment guide rod 2221 is locked and fixed by the locking mechanism. The external air pump is activated. The air pump draws air through the connecting pipe between the contact surface of the tail suction cup 2222 and the shaped tail h, creating a negative pressure state, thereby fixing the tail to facilitate the cutting of the shaped tail h by the cutting head c. The bottom support block 1221 of the first auxiliary support assembly 122 abuts against the shaped tail h, providing good support. In addition, the auxiliary support mechanism can also move up and down under the support of the auxiliary support cylinder 2231 to support shaped tails of different shapes and better support the shaped tail h.

[0123] First, the second moving assembly 21 is started by an external control body, so that the moving support 111 of the second moving assembly 21 can move along the length direction of the processing platform a toward the tail end of the silicon rod under the drive of the travel motor, thereby driving the second supporting assembly 22 to approach the tail end of the silicon rod.

[0124] Next, when the second supporting component 22 is against the tail end face of the silicon rod, the tail suction cup 2222 can adaptively control the distance between the tail suction cup 2222 and the special-shaped tail h under the adjustment of the guide rod 2221, so that the tail suction cup 2222 can be against the special-shaped tail h, and the contact area is larger, thereby improving the supporting effect, and then the second moving component 21 is controlled to stop moving through the control body.

[0125] Then, the tail suction cup 2222 of the adsorption structure 222 of the second supporting assembly 22 adsorbs and fixes the special-shaped tail h at the tail end of the silicon rod.

[0126] The control body then controls the cutting head c to cut the irregular tail h fixed in step S3. The control body also controls the external air pump to stop, separating the tail suction cup 2222 of the second support assembly 22 from the irregular tail h, allowing the irregular tail h to fall onto the second movable assembly 21, and then stopping the second support assembly 22. After stopping, the second support assembly 22 moves synchronously with the second movable assembly 21.

[0127] Finally, the control unit controls the second movable assembly 21 to move the movable support 111 along the length of the processing platform a, away from the tail end of the silicon ingot. This drives the special-shaped tail h on the buffer cylinder 1132 of the second movable assembly 21 in step S5 to the unloading position and is grasped by the robot arm and placed into the waste collection box. It should be noted that the head unloading device is also controlled by the control unit.

[0128] This embodiment provides a cutting device for cutting the irregular tail of a silicon ingot. A second moving assembly 21 drives a second supporting assembly 22 to slide relative to a processing platform a toward the irregular tail h until the second supporting assembly 22 abuts against the irregular tail h, providing support from one end and the bottom of the silicon ingot. This supports the cutting head to cut the tail of the silicon ingot. The cut irregular tail h is then transported to a cutting position for fully automatic cutting, eliminating the need for manual cutting. This improves cutting efficiency and provides more convenient and effective support than manual cutting. This device addresses the current problem of manually inserting a wedge under the irregular tail h to pad the tapered surface before cutting the irregular tail h. Furthermore, after cutting, the irregular tail h is also manually removed. This reduces work efficiency and increases labor intensity, requiring more personnel, leading to increased costs for cutting the silicon ingot.

[0129] A sampling device and a feeding system for silicon rods are disclosed. The sampling device 1 can support the head of the silicon rod or support and absorb a sample for cutting, and transport the cut head or sample to a first feeding position and a second feeding position, respectively. A tail feeding device 2 can move along a processing platform a toward or away from the tail of the silicon rod, so that the tail feeding device 2 supports the tail of the silicon rod and transports the cut tail to a third feeding position. Manual feeding is not required, improving feeding efficiency. Compared with manual feeding, the support is convenient and effective. The system solves the current problem of manually removing irregularly shaped heads and tails of silicon rods, which generally involves inserting wedges under the irregularly shaped heads and tails, padding the irregularly shaped conical or wavy surfaces, and then cutting the irregularly shaped heads and tails. Furthermore, the cutting process also involves manual handling of the irregularly shaped heads and tails, which not only reduces work efficiency but also increases labor intensity and requires more personnel, leading to increased costs for silicon rod cutting. Moreover, the sample is directly taken out by the sampling device, which improves the detection accuracy and detection effect of the sample compared with the existing manual sampling.
