Description

Technical Field

[0001] The present invention relates to the field of material processing equipment, and in particular to 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 crystal bars, in order to improve the cutting efficiency, a common method is to increase the number of cutting stations to achieve the purpose of cutting multiple crystal bars at the same time. However, when loading, the existing crystal bar cutting system delivers the crystal bar from the previous processing system or the raw material warehouse to the transfer device of the current crystal bar cutting system through a delivery device, and the transfer device then transfers the crystal bar to the cutting station. This operation method can usually only deliver one crystal bar at a time, and after one processing is completed, it is necessary to wait for the unloading to be completed before the next radial loading. For a multi-station crystal bar processing system, this loading and unloading method will affect the processing efficiency because the loading time is too long.

[0004] In addition, as the number of cutting stations increases, the number of ingot cutting heads and ingot clamping devices also increases accordingly. On the one hand, during multi-station processing, the time and path for loading and unloading materials and unloading the edge skin become longer, resulting in a significant reduction in overall processing efficiency; on the other hand, for multi-station cutting processing, the arrangement and control methods of the various components of the equipment are relatively complex, and the overall size and occupied space of the equipment increase, resulting in poor operating stability and difficulty in maintenance.

The first crystal rod clamping claw assembly and the second crystal rod clamping claw assembly are rotatably arranged on the crystal rod transfer device, which can clamp the crystal rod to be processed and the processed crystal rod at the same time, so as to realize loading and unloading in one loading and unloading stroke, thereby shortening the loading and unloading time.

[0025] 2. The material clamping device on the rotating loading platform can provide the crystal rod transfer device with the crystal rod to be processed, and can also receive the processed crystal rod, further shortening the loading and unloading time.

[0026] 3. There are multiple crystal rod clamping stations on the rotating loading table, which can realize rapid loading and unloading of multiple cutting stations in conjunction with the crystal rod handling device.

[0027] 4. The rotating loading platform and the crystal rod transfer device cooperate to realize the loading and unloading of crystal rods. The overall structure is compact and occupies little space.

[0028] 5. The water receiving unit of the rotating loading platform receives the water dripping from the crystal rod above, which will not affect the equipment under the rotating loading platform and will not cause water accumulation on the ground.

[0029] 6. The first lifting drive assembly, the second lifting drive assembly and the rotary drive assembly are all arranged inside the rotary frame of the rotary clamping unit, so that the overall structure of the rotary clamping unit is compact and the volume is small, making the operation of the equipment more stable.

[0032] 9. The first head assembly and the second head assembly in the crystal rod cutting device are arranged back to back on both sides of the feed assembly. This arrangement makes the overall layout more compact and occupies less space.

[0033] 10. Two or more cutting stations can be set between the same group of machine heads to cut two or more crystal bars at the same time, which not only increases the processing quantity, but also has a good cutting effect and more stable operation.

[0034] 11. The cutting unit can not only square round bars, but also cut half bars, which diversifies the processing methods and improves the processing efficiency.

[0035] 12. 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.

[0036] 13. The side skin material unloading device cooperates with the single-sided opening structure on 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.

A loading and unloading platform 11 is rotatably arranged on the flip table 1. The loading and unloading platform 11 flips between the horizontal direction and the vertical direction to drive the crystal rod to flip between the horizontal placement and the vertical placement, and provides the rotating loading platform 2 with the crystal rod to be processed or transfers the processed crystal rod on the rotating loading platform 2.

[0089] Further, if Figures 1 to 7 As shown, the crystal rod transport device 3 in the present invention includes a rotary clamping unit 31, a transport translation unit 32 and a translation guide rail 33, wherein:

[0090] The translation guide rail 33 is extended along each cutting station of the crystal ingot processing system, and the transfer translation unit 32 is slidably set on the translation guide rail 33. The crystal ingot transfer device 3 is moved along the multiple cutting stations of the crystal ingot processing system by controlling the transfer translation unit 32 to move on the translation guide rail 33. Specifically, since the cutting unit 200 includes multiple processing chambers, the transfer translation unit 32 slides along the translation guide rail 22 and can be moved to the cutting station of each processing chamber.

[0091] In a preferred embodiment of the present invention, the rotating loading platform 2 is arranged at one end of the translation guide rail 33, and the crystal rod transfer device 3 is moved between the rotating loading platform 2 and each cutting station by controlling the transfer translation unit 32 to move on the translation guide rail 33, thereby realizing the loading and unloading of crystal rods between the rotating loading platform 2 and each cutting station.

[0092] The crystal ingot transfer device 3 can reciprocate between the rotating loading platform 2 and the multiple crystal ingot processing stations of the crystal ingot processing system to complete the loading and unloading of the crystal ingot. Specifically, the crystal ingot transfer device 3 can transport the crystal ingot to be processed from the loading and clamping device 213 to the crystal ingot processing station, and / or transport the processed crystal ingot from the crystal ingot processing station to the loading and clamping device 213.

[0093] Furthermore, the crystal rod transfer device 3 includes a rotary clamping unit 31, which is rotatably set on the transfer translation unit 32. The first crystal rod clamping assembly 312 and the second crystal rod clamping assembly 314 are respectively provided on different sides of the rotary clamping unit 31. The first crystal rod clamping assembly 312 or the second crystal rod clamping assembly 314 is rotated on the crystal rod transfer device 3 by controlling the rotation of the rotary clamping unit 31.

[0094] Furthermore, the rotary clamping unit 31 includes a rotary frame 311, a first crystal rod clamping assembly 312 is arranged on one side of the rotary frame 311, a first lifting drive assembly 313 is fixedly arranged inside the rotary frame 311, the first lifting drive assembly 313 is connected to the first crystal rod clamping assembly 312 to drive the first crystal rod clamping assembly 312 to reciprocate on the rotary frame 311; a second crystal rod clamping assembly 314 is arranged on the other side of the rotary frame 311, a second lifting drive assembly 315 is fixedly arranged inside the rotary frame 311, the second lifting drive assembly 315 is connected to the second crystal rod clamping assembly 314 to drive the second crystal rod clamping assembly 314 to reciprocate on the rotary frame 311.

[0095] In a specific embodiment of the present invention, the first crystal rod clamping assembly 312 is used to clamp round rods, and the second crystal rod clamping assembly 314 is used to clamp square rods. The rotating frame 311 is controlled to rotate as a whole to rotate the first crystal rod clamping assembly 312 or the second crystal rod clamping assembly 314 to the crystal rod picking and placing station to perform the crystal rod picking and placing operation.

[0096] Furthermore, a rotary drive unit 316 is fixedly installed inside the rotary frame 311, and the rotary drive unit 316 is rotatably connected to the transfer translation unit 32, and can drive the rotary frame 311 to rotate on the transfer translation unit 32, so that the first crystal rod clamping assembly 312 or the second crystal rod clamping assembly 314 is located at the crystal rod picking and placing station.

[0097] The revolving frame 311 in the present invention is as follows: Figure 8 , Fig. 9 As shown, the rotating frame 311 is a frame-like structure, and each modular clamping module is installed on the rotating frame 311. The driving component is installed inside the rotating frame 311. While fully utilizing the internal space of the rotating frame 311, the overall structure of the rotating clamping unit 31 is compact and occupies a small space, which is conducive to rotation and clamping control.

[0098] Furthermore, the first crystal rod clamping assembly 312 and the second crystal rod clamping assembly 314 in the present invention can be a pair, arranged back to back on the rotating frame 311, so as to realize the loading and unloading of the cutting station in one loading and unloading translation movement. The first crystal rod clamping assembly 312 and the second crystal rod clamping assembly 314 can also be two pairs or more pairs. When the first crystal rod clamping assembly 312 and the second crystal rod clamping assembly 314 are one pair or two pairs, the rotating frame 311 is a cubic structure. When the first crystal rod clamping assembly 312 and the second crystal rod clamping assembly 314 are multiple pairs, the rotating frame 311 is a polyhedron structure, so that the first crystal rod clamping assembly 312 and the second crystal rod clamping assembly 314 are staggered on different sides of the rotating frame 311.

[0099] After the revolving frame 311 in the present invention is embedded with various functional modules, the revolving frame 311 is sealed as a whole using sealing materials to ensure that the internal driving components of the revolving frame 311 are not affected by external water stains, making the equipment run more stably.

Specifically, the swivel base 322 moves along the transport translation base 321 to enter the crystal ingot processing chamber to clamp or place the crystal ingot.

[0101] Furthermore, the first crystal rod clamping jaw assembly 312 includes an upper clamping jaw module 3121 and a lower clamping jaw module 3122. The upper clamping jaw module 3121 and the lower clamping jaw module 3122 each include two symmetrically arranged clamping jaws 3101. The clamping surface of the clamping jaw 3101 is adapted to the shape of the crystal rod, and the clamping surface is provided with a soft pad to increase the contact area and friction with the crystal rod.

[0102] Furthermore, when the first crystal rod clamping jaw assembly 312 is used to clamp a round rod, the clamping surfaces of the two clamping jaws 3101 of the upper clamping jaw module 3121 and the lower clamping jaw module 3122 are adapted to the side shape of the round rod. Specifically, the surface of the clamping jaw 3101 is a V-shaped structure so as to fit the side of the round rod when clamping the round rod.

[0103] Reference Figures 11 to 13 The upper clamping jaw module 3121 and the lower clamping jaw module 3122 are both slidably connected to the rotating frame 311 through the clamping jaw bottom plate 3100, and the clamping jaws 3101 of the upper clamping jaw module 3121 and the lower clamping jaw module 3122 are both arranged on the outer side of the clamping jaw bottom plate 3100. The inner side of the clamping jaw bottom plate 3100 is provided with a clamping jaw driving assembly, and the clamping jaw driving assembly drives the two clamping jaws 3101 to slide along the clamping jaw bottom plate 3100 to achieve the clamping and loosening of the crystal rod. The clamping jaw bottom plate 3100 is movably provided with a synchronous reverse motion gear, and the two clamping jaws 3101 are respectively connected to the clamping jaw 3101 synchronous reverse motion gear through a rack, so that the movement stroke of the two clamping jaws 3101 is the same.

[0104] Furthermore, a crystal rod probe 3105 is provided between the two clamping jaws 3101 for performing crystal line detection on the silicon rod when the clamping jaws 3101 clamp the silicon rod for loading.

[0105] Furthermore, a clamp driving assembly is provided on the inner side of the clamp bottom plate 3100, which is used to drive the two clamps 3101 to move left and right. The clamp driving assembly includes a clamp driving cylinder 3104 connected to the two clamps 3101 respectively, the cylinder body of the clamp driving cylinder 3104 is fixedly connected to the clamp bottom plate 3100, and the movable end of the clamp driving cylinder 3104 is connected to the clamp 3101. By controlling the extension and retraction of the clamp driving cylinder 3104, the two clamps 3101 are respectively moved left and right to clamp and release the crystal rod.

[0106] Furthermore, a slider connection seat 3108 is also provided on the inner side surface of the clamp base plate 3100 , which is connected to the clamp module slide rail 3111 on the rotating frame 311 through the slider connection seat 3108 to realize the reciprocating motion of the clamp module on the rotating frame 311 .

[0107] On the basis of the same basic structure of each clamping module, the present invention makes adaptive adjustments to the clamping jaws 3101 of the clamping jaws module for clamping the crystal rod to adapt to clamping different crystal rods. For the round rod clamping jaw module for clamping the round rod, its front end clamping jaw 3101 is a V-shaped structure to increase the contact area with the side of the crystal rod. For the clamping jaw 3101 for clamping the square rod, its front end clamping jaw 3101 is a planar structure to increase the contact area with the side of the crystal rod. In addition, the surface of each clamping jaw 3101 is provided with a soft pad to further increase the friction with the crystal rod, so as to achieve stable and reliable clamping of the crystal rod.

[0108] Furthermore, since the first crystal rod clamping assembly 312 has two clamping modules, it is necessary to adjust the distance between the two clamping modules to adapt to clamping crystal rods of different lengths, and the positions of the two clamping modules can be adjusted at the same time to achieve the overall movement of the crystal rod. Therefore, in the embodiment of the present invention, the upper clamping module 3121 is fixedly connected to the first lifting drive assembly 313 to reciprocate under the drive of the first lifting drive assembly 313, and the lower clamping module 3122 is clutch-connected with the first lifting drive assembly 313. When the lower clamping module 3122 is fixedly connected to the first lifting drive assembly 313, the lower clamping module 3122 can reciprocate under the drive of the first lifting drive assembly 313. When the lower clamping module 3122 is disconnected from the first lifting drive assembly 313, the lower clamping module 3122 can maintain a preset position on the rotating frame 311. The preset position of the lower clamping module 3122 is specifically the lower limit position of the lower clamping module 3122.

[0109] Reference Fig. 9 , Fig.10 and Fig.14 The first lifting drive assembly 313 of the present invention specifically includes a slewing chain 3131 and a slewing chain drive assembly 3132. The upper clamping jaw module 3121 is fixedly connected to the slewing chain 3131 through a fixed connection seat 3134. The lower clamping jaw module 3122 is clutch-connected to the slewing chain 3131. The slewing chain drive assembly 3132 drives the slewing chain 3131 to rotate, so as to realize the reciprocating motion of the upper clamping jaw module 3121 and the lower clamping jaw module 3122. The slewing chain 3131 of the embodiment of the present invention is an endless chain. A transmission sprocket 3133 may be provided at both ends of the slewing chain 3131. The rotation of the slewing chain 3131 is realized by driving at least one transmission sprocket 3133 to rotate.

[0110] Furthermore, the lower clamping jaw module 3122 is connected to the rotary chain 3131 by a chain clutch device 3135. The chain clutch device 3135 includes a chain fixing seat 31351 and a chain clutch seat 31352. The lower clamping jaw module 3122 is fixedly connected to the chain clutch seat 31352. A locking slider 31353 is movably provided on the chain clutch seat 31352. A middle gap is formed between the locking slider 31353 and the chain fixing seat 31351. The rotary chain 3131 is locked from the middle gap. The locking slider 31353 can move forward and backward relative to the chain fixing seat 31351, wherein the locking slider 31353 is driven by the locking slider driving cylinder 31354 to move forward and backward. When the locking slider driving cylinder 31354 pushes the locking slider 31353 to move forward, the toothed structure at the front end of the locking slider 31353 meshes with the rotary chain 3131 and is mutually locked with the rotary chain 3131, so that the locking slider 31353 can reciprocate with the rotation of the rotary chain 3131. When the locking slider driving cylinder 31354 drives the locking slider 31353 to move backward, the toothed structure at the front end of the locking slider 31353 is separated from the rotary chain 3131, and the lower clamping jaw module 3122 is maintained at the lower limit position of the lower clamping jaw module 3122.

[0111] In a specific embodiment of the present invention, the distance between the upper clamping module 3121 and the lower clamping module 3122 is adjusted by adjusting the upper clamping module 3121 separately to adapt to clamping crystal rods of different lengths. The overall lifting of the crystal rod is achieved by driving the upper clamping module 3121 and the lower clamping module 3122 to move together at the same time. Compared with lifting drive assemblies with similar functions, the first lifting drive assembly 313 provided in the embodiment of the present invention is simpler to control and has a simpler structure, which is more conducive to the stability of the overall control.

[0112] Furthermore, the first lifting drive assembly 313 in the present invention further includes a chain tensioner 3136 , and the chain tensioner 3136 can adjust the extension length of the rotary chain 3131 to tighten or loosen the rotary chain 3131 .

[0113] Specifically, the chain tensioning device 3136 includes a tensioning frame, on which a tensioning shaft 31365 is provided. The tensioning shaft 31365 can move on the tensioning frame, and a transmission sprocket 3133 is provided on the tensioning shaft 31365, that is, a transmission sprocket 3133 corresponding to the rotating chain 3131. The rotating chain 3131 is wound around the transmission sprocket 3133. The extension length of the rotating chain 3131 can be adjusted by adjusting the position of the tensioning shaft 31365 on the tensioning frame.

[0114] Furthermore, the tensioning frame includes a lower seat plate 31361 and an upper top plate 31363, and a tensioning plate 31362 connected between the lower seat plate 31361 and the upper top plate 31363. The tensioning plate 31362 is provided with a long hole for the tensioning shaft 31365 to pass through. The tensioning shaft 31365 is connected to the upper top plate 31363 by a bolt adjustment assembly 31364. The bolt adjustment assembly 31364 can adjust the relative position of the tensioning shaft 31365 and the upper top plate 31363 to adjust the position of the tensioning shaft 31365 on the tensioning frame. The bolt adjustment assembly 31364 specifically includes a lead screw and two locking nuts that cooperate with the lead screw. The head of the lead screw is fixedly connected to the tensioning shaft 31365. The other end of the lead screw is threaded and passes through the screw hole on the upper top plate 31363. The two locking nuts are respectively located on both sides of the upper top plate 31363. By adjusting the positions of the two locking nuts on the lead screw, the relative positions of the tensioning shaft 31365 and the upper top plate 31363 are adjusted to finally achieve the tightening and loosening of the slewing chain 3131. When the slewing chain 3131 is loose and needs to be tightened, loosen the locking nuts on the upper and lower sides of the lead screw, adjust the lead screw to a suitable distance in the direction close to the lower seat plate 31361, and then lock the two locking nuts to tighten the chain.

[0115] In a specific embodiment of the present invention, the rotating chain 3131 is arranged at the upper and lower ends of the rotating frame 311 through the transmission sprocket 3133, one of the transmission sprockets 3133 is connected to the chain tensioner, the lower seat plate of the tensioner is fixedly connected to one end face of the rotating frame 311, and the other transmission sprocket 3133 is connected to the rotating chain driving assembly 3132 to drive the overall rotation of the rotating chain 3131, and the rotating chain driving assembly 3132 is fixedly connected to the other end face of the rotating frame 311.

[0116] like Fig.15 As shown, the second crystal rod clamping jaw assembly 314 of the embodiment of the present invention includes two symmetrically arranged clamping jaws 3101, and a support 3141 is arranged at the bottom end of the clamping jaw 3101 to lift the crystal rod from the bottom end face of the crystal rod. The clamping surface of the clamping jaw 3101 is adapted to the shape of the crystal rod, and the clamping surface is provided with a soft pad to increase the contact area and friction with the crystal rod.

[0117] In a specific embodiment of the present invention, the second crystal rod clamping jaw assembly 314 is used to clamp the square rod, so the clamping surface of the clamping jaw 3101 is a planar structure, which increases the friction of the crystal rod clamping. Moreover, since the bottom end face of the square rod is square, the support 3141 is set at the bottom end of the clamping jaw 3101 to support both sides of the square rod and stably clamp the square rod. In addition, the clamping jaw drive, connection with the rotating frame 311, and crystal rod detection of the second crystal rod clamping jaw assembly 314 are basically the same as those of the upper clamping jaw module 3121 and the lower clamping jaw module 3122, and will not be repeated here.

[0118] Furthermore, the second lifting drive assembly 315 includes a lifting drive motor 3151, to which a lifting screw 3152 is rotatably connected, and a screw nut seat is fixedly connected to the second crystal rod clamp assembly 314, which is connected to the lifting screw 3152. The lifting drive motor 3151 drives the lifting screw 3152 to rotate, so as to realize the reciprocating motion of the second crystal rod clamp assembly 314.

[0119] In addition, in the embodiment of the present invention, it is also necessary to control the lower limit position of the upper clamping jaw module 3121, the lower clamping jaw module 3122 and the second crystal ingot clamping jaw assembly 314. The first crystal ingot clamping jaw assembly 312 and / or the second crystal ingot clamping jaw assembly 314 are provided with a limit block 3107, and the rotating frame 311 is respectively provided with a limit block 3112 corresponding to each limit block, and the limit block 3107 abuts against the limit block 3112 to limit the lower limit position of the first crystal ingot clamping jaw assembly 312 and / or the second crystal ingot clamping jaw assembly 314.

[0120] Reference Figures 16 to 19 The rotating loading platform 2 in the present invention includes a rotating loading unit 21, an electrical unit 22 and a water receiving unit 23. The functions and specific structures of each unit module of the rotating loading platform 2 in the embodiment of the present invention are described in detail below.

[0121] The rotating loading unit 21 can rotate on the rotating loading platform 2. A plurality of crystal rod clamping stations are arranged on the rotating loading unit 21. Each crystal rod clamping station is provided with a loading clamping device 213 for providing or receiving the crystal rod. The position of different crystal rod clamping stations is converted by controlling the rotation of the rotating loading unit 21 to facilitate the removal and placement of the crystal rod from each crystal rod clamping station.

[0122] The electrical unit 22 includes an electrical fixed part 221 and an electrical rotating part 222. The electrical fixed part 221 is connected to an external energy input device, and the electrical rotating part 222 is fixedly arranged on the rotating loading unit 21 and can rotate with the rotating loading unit 21. The electrical fixed part 221 is connected to the electrical rotating part 222 through a slip ring assembly, and the electrical rotating part 222 is connected to the electrical equipment in the rotating loading unit 21 through an electrical line to provide energy power for the electrical equipment in the rotating loading unit 21.

[0123] Furthermore, the external energy specifically includes an air source of a pneumatic device and a power source of an electric device. The pneumatic device specifically can be a cylinder, and the electric device specifically can be an electrical component such as a motor, a sensor, a processor, etc. Since there is no relative motion between the electrical rotating part 222 and the rotating material loading unit 21, the line winding problem caused by the rotation of the rotating material loading unit 21 is avoided.

[0124] The water receiving unit 23 is arranged below the rotating loading unit 21 of the rotating loading platform 2, and a rotating driving unit 24 is arranged below the water receiving unit 23. The water receiving unit 23 is used to receive water stains flowing down from the rotating loading unit 21 to avoid water stains splashing onto the rotating driving unit 24 and prevent water accumulation on the ground.

[0125] Furthermore, the rotary loading platform 2 of the embodiment of the present invention further comprises a turntable frame 25 fixedly connected to the rotary loading platform base, and a rotary driving unit 24 is mounted on the turntable frame 25 for driving the rotary loading unit 21 to rotate.

[0126] In a specific embodiment of the present invention, the rotary drive unit 24 specifically includes a rotary servo motor 241, a rotary reducer 242, a rotary bearing 243 and a connecting plate 244. The rotary servo motor 241 is connected to the rotary reducer 242 and fixed on the turntable frame 25. The inner ring of the rotary bearing 243 is fixedly connected to the turntable frame 25, and the outer ring of the rotary bearing 243 is respectively connected to the rotary reducer 242 and the rotary loading unit 21. The outer ring of the rotary bearing 243 is connected to the rotary loading unit 21 through the connecting plate 244. Driven by the rotary servo motor 241, the connecting plate 244 rotates with the rotating shaft of the rotary drive unit 24, and the rotary loading unit 21 is also fixedly connected to the connecting plate 244, so as to drive the entire rotary loading unit 21 to rotate through the connecting plate 244. The rotary bearing 243 of the embodiment of the present invention can be a cross roller bearing, so as to improve the control accuracy of the rotation angle. Of course, the rotary bearing 243 of the embodiment of the present invention can also select other bearing structures.

[0127] Furthermore, the rotary loading unit 21 of the embodiment of the present invention specifically includes a turntable 211 and a plurality of loading clamping devices 213 disposed on the turntable 211, and the loading clamping device 213 corresponds to a crystal rod clamping station for clamping the crystal rod. The loading clamping device 213 is disposed perpendicular to the turntable 211 to clamp the crystal rod in a vertical posture, and the loading clamping device 213 is distributed at different positions around the turntable 211, which makes full use of the spatial structure, makes the rotary loading unit 21 compact, and facilitates the cooperation with other equipment to realize the rapid and stable placement of the crystal rod.

[0128] Further, the turntable 211 includes at least two turntable side arms 2111 radiating outward from the center of the turntable 211. One end of each turntable side arm 2111 is connected to each other at the center of the turntable 211, and is rotatably connected to the rotation drive unit 24 through a connecting plate. A loading support column 212 is vertically arranged on each turntable side arm 2111, and a loading clamping device 213 is arranged on the loading support column 212. One end of the loading support column 212 is fixedly connected to the turntable 211, and the other end extends vertically upward. The loading support column 212 can provide vertical support for the loading clamping device 213. Two loading clamping devices 213 can be arranged on the side arm of each loading support column 212 at the same time to make full use of the structural space of the rotating loading unit 21. The rotation of the turntable 211 is controlled to drive the loading clamping device 213 on the turntable 211 to rotate.

[0129] As can be seen from the accompanying drawings, the turntable 211 of the embodiment of the present invention forms a frame-like structure through turntable side arms 2111 radiating in different directions, and the turntable 211 has a preset operating distance relative to the bottom equipment, so that when the rotating loading platform 2 and the turning table 1 or the crystal rod transfer device are docked with each other to realize the crystal rod transfer, sufficient operating space is reserved for the crystal rod clamping device of the turning table 1 and the crystal rod transfer device. In the embodiment of the present invention, the bottom equipment of the turntable 211 is specifically a water receiving unit 23.

[0130] In a specific embodiment of the present invention, the angles between the turntable side arms 2111 are equal, that is, the turntable side arms 2111 are evenly arranged in the circumferential direction of the center of the rotating shaft, so that the loading and clamping devices 213 are evenly distributed on the turntable 211. In actual use, the angles between the turntable side arms 2111 can also be set to be unequal to meet other requirements of the on-site working conditions, such as making the rotating loading unit 21 dock with the flip table 1 and the crystal rod transfer device at the same time. Therefore, the unequal angles between the turntable side arms 2111 also fall within the protection scope of the present invention. In addition, each turntable side arm 2111 of the embodiment of the present invention is preferably configured to have two loading and clamping devices 213 to fully utilize the spatial position of the turntable 211 while making the position of each crystal rod not too compact, and the two loading and clamping devices 213 are distributed on different sides of the loading support column 212. Of course, in actual use, one or more loading and clamping devices 213 can also be set for each turntable side arm 2111 as needed.

[0131] Fig.16The specific structure of the rotating material loading unit 21 when there are two turntable side arms 2111 in the present invention is shown. When there are two turntable side arms 2111, the turntable 211 is in a straight line structure as a whole, and a total of four material loading clamping devices 213 are arranged on the turntable 211 of the straight line structure. It can be understood that the number of material loading clamping devices 213 in the embodiment of the present invention is not limited to four, and can be set according to needs. For example, when the number of turntable side arms 2111 is three, the turntable 211 forms a Y-shaped structure as a whole, and at this time, the material loading clamping devices 213 can be set to six. The specific structure of the turntable 211 and the number of material loading clamping devices 213 in the embodiment of the present invention depend on the structural space and specific needs. In a specific embodiment of the present invention, the loading and clamping device 213 is arranged on two opposite sides of the loading support column 212, so that there are two crystal rod clamping stations corresponding to the loading and clamping devices 213 on the rotating loading unit 21 facing the same side. At this time, the crystal rods of the two crystal rod clamping stations can be docked by rotating the rotating loading unit 21 once.

[0132] Specifically, refer to Figures 16 to 19 The material loading and clamping device 213 in the present invention includes a pad 2131 and a pressure plate 2132, which are clamped at both ends of the crystal rod in the axial direction, so that the crystal rod is in a vertical state, so as to facilitate the taking and placing of the crystal rod from the side of the crystal rod. The effective clamping surface of the pad 2131 and / or the pressure plate 2132 and the crystal rod is smaller than the end face of the crystal rod, so as to reserve a receiving space when the crystal rod is taken and placed from the axial end face of the crystal rod. The material loading and clamping device 213 provided by the present invention can meet the requirements of taking and placing the crystal rod from the side of the crystal rod, and can also meet the requirements of taking and placing the crystal rod from the axial end face of the crystal rod, so as to adapt to the clamping requirements of different crystal rod clamping devices, that is, in the specific embodiment of the present invention, it can simultaneously meet the requirements of the rapid taking and placing of the vertical crystal rod clamping device of the turning table 1, and can also meet the requirements of the rapid taking and placing of the horizontal crystal rod clamping device of the crystal rod transport device. It can be understood that the flip table 1 and the crystal rod transfer device of the above embodiment are only a specific embodiment, which is used to illustrate that the material loading and clamping device 213 provided in the embodiment of the present invention can provide both lateral clamping space and transverse clamping space, and how to clamp the crystal rod in which operation process is not the content of limiting the protection scope of the present invention. Among them, the effective clamping surface can be understood as the contact surface with the crystal rod when clamping the crystal rod.

[0133] Further, the pad 2131 is an integrated planar structure or a multi-bracket structure. When clamping the crystal rod, the pad 2131 and the effective clamping surface of the crystal rod cover the center of the end face of the crystal rod to provide a stable support force for the crystal rod. Specifically, the effective clamping surface covers the center of the end face of the crystal rod, and the effective clamping surface coincides with the center of the crystal rod, or the plane formed by multiple effective clamping surfaces coincides with the center of the crystal rod. Specifically, the pad 2131 can be a planar structure extending outward along the turntable side arm 2111, and the specific extension angle is related to the number of turntable side arms 2111 on the turntable 211 and the relative positions of the flip table 1, the crystal rod transfer device and the rotating loading platform 2. The position setting of the pad 2131 is preferably that the direction of the pad 2131 extending outward corresponds to the direction of the flip table 1 after vertical flipping, the position of the pad 2131 corresponds to the position of the crystal rod clamping device on the crystal rod transfer device, and the pressure plate 2132 extends outward in the same direction as the pad 2131.

[0134] Furthermore, since the material loading clamping device 213 in the present invention needs to realize the crystal bar transfer with other crystal bar clamping devices, the stability and reliability of different crystal bar clamping devices when transferring the crystal bar should be considered. The present invention can facilitate the horizontally clamped crystal bar clamping device to grasp the crystal bar through the side of the crystal bar by vertically clamping the crystal bar. The crystal bar clamping device for vertically clamping the crystal bar can also realize rapid clamping from the two axial ends of the crystal bar by rationally arranging the structural form of the pad 2131 and the pressure plate 2132.

[0135] Furthermore, the effective clamping surface of the pad 2131 and the crystal rod has a preset contact area on both sides or in the middle of the lower end surface of the crystal rod, so as to reserve a supporting space. For example, when the pad 2131 of the embodiment of the present invention is an integrated planar structure, the pad 2131 is used to support the center position of the bottom of the crystal rod, and sufficient contact space with the lower end surface of the crystal rod is reserved on both sides of the pad 2131, so that the lower clamping jaws of the vertical crystal rod clamping device can also stably support the crystal rod. Specifically, the lower clamping jaws of the vertical crystal rod clamping device can be two outwardly extending brackets. When docking with the material loading clamping device 213, the two outwardly extending brackets are located on both sides of the pad 2131. It can be understood that the pad 2131 and the lower clamping jaws of the vertical crystal rod clamping device can be interchanged to achieve the above functions.

[0136] Furthermore, in practical applications, when the crystal rod clamping device transports the crystal rod, it is also necessary to consider reserving movement space for the crystal rod clamping device. If the crystal rod is transported from top to bottom, it is also necessary to reserve longitudinal space for the lower clamping jaw of the crystal rod clamping device to move up and down. Therefore, a preset space is formed under the pad 2131 of the embodiment of the present invention to reserve longitudinal space for up and down movement when the crystal rod is taken and placed from the axial end face of the crystal rod. In a specific embodiment of the present invention, a preset distance is left between the turntable 211 and the water receiving tray 231, so as to reserve longitudinal space for the lower clamping jaw of the crystal rod clamping device to move up and down.

[0137] Furthermore, the pressure plate 2132 of the material loading clamping device 213 of the present invention and the upper clamping jaw of the vertical crystal rod clamping device also need to be arranged in coordination, that is, the pressure plate 2132 and the effective clamping surface of the crystal rod leave a preset contact area on both sides or in the middle of the upper end surface of the crystal rod compared to the crystal rod, so as to reserve a clamping space. For the crystal rod clamping device for vertically clamping the crystal rod, the lower clamping jaw supports the weight of the entire crystal rod and the clamping force applied by the upper clamping jaw. Therefore, for the pressure plate 2132 of the crystal rod clamping device of the embodiment of the present invention, it is only necessary to provide a stable clamping force for the crystal rod when clamping the crystal rod so that the crystal rod will not be thrown out or tipped over. Therefore, the pressing plate 2132 of the embodiment of the present invention includes a pressing plate bracket 21321 and a pressing plate protrusion 21322. The pressing plate bracket 21321 is an L-shaped structure composed of two side arms. One side arm of the pressing plate bracket 21321 is slidably connected to the material loading support column 212, and the end of the other side arm of the pressing plate bracket 21321 is connected to the pressing plate protrusion 21322. The lower end surface of the pressing plate protrusion 21322 contacts the upper end surface of the crystal rod to form an effective clamping surface with the crystal rod. A connecting beam 21323 is provided between the two side arms of the frame 21321 to improve the stability of the pressure plate bracket 21321. The lower end surface of the pressure plate protrusion 21322 contacts the upper end surface of the crystal rod and covers the center of the upper end surface of the crystal rod. The area of ​​the lower end surface of the pressure plate protrusion 21322 in the present invention can be very small compared to the area of ​​the upper end surface of the crystal rod, so as to provide a stable clamping force for the crystal rod while reserving a clamping space and an up and down movement space for the upper clamping jaw of the crystal rod clamping device.

[0138] Furthermore, since the material loading and clamping device 213 is arranged on the turntable 211, the crystal rod clamped by the material loading and clamping device 213 will also rotate with the rotation of the turntable 211, and the clamped crystal rod will be subjected to the centrifugal force. Therefore, in order to resist the centrifugal force, the surface of the pad 2131 and / or the pressure plate 2132 is a soft material, specifically, the upper end surface of the pad 2131 and the lower end surface of the protrusion of the pressure plate 2132 are soft materials to increase the friction with the end surface of the crystal rod. In addition, the surface of the pad 2131 and / or the pressure plate 2132 is a soft material, which can also reduce the collision damage with the crystal rod. In the following embodiment, the lower surface of the pressure plate 2132 is the contact surface with the upper end surface of the crystal rod.

[0139] Furthermore, since the lower surface of the pressing plate 2132 is made of a soft material, the lower surface of the pressing plate 2132 is at a preset angle to the horizontal plane, so as to provide a horizontal component force for the crystal rod to resist the centrifugal force when the crystal rod is clamped. The size of the preset angle is related to the rotation speed range of the turntable 211 in actual application, and is intended to prevent the crystal rod from being thrown away by the centrifugal force. It can be understood that since the surface of the pressing plate 2132 is elastic, even if the surface of the pressing plate 2132 is at a preset angle to the upper end face of the crystal rod, when the pressing plate 2132 is pressed downward, it will be in plane contact with the upper end face of the crystal rod, because the elastic material on the lower surface of the pressing plate 2132 provides the crystal rod with a component force that can resist the centrifugal force.

[0140] Furthermore, the pad 2131 and the pressure plate 2132 in the present invention are arranged to extend laterally in the same direction along the loading support column 212 to reserve lateral clamping space for the crystal rod, so as to facilitate the lateral removal and placement of the crystal rod from the crystal rod. The present invention reserves sufficient lateral space for the crystal rod when clamping the crystal rod by arranging the pad 2131 and the pressure plate 2132 on the same side of the loading support column 212 in the lateral direction, so as to facilitate the lateral clamping of the crystal rod to quickly remove and place the crystal rod. Among them, the pad 2131 and the loading support column 212 are relatively fixedly arranged, and the pressure plate 2132 can move up and down along the loading support column 212 to achieve the clamping and loosening of the crystal rod.

[0141] In a specific embodiment of the present invention, the pad 2131 is fixedly connected to the turntable 211, and the pressure plate 2132 can move vertically up and down to achieve the compression and loosening of the crystal rod. Specifically, the up and down movement of the pressure plate 2132 is achieved by the vertically arranged pressure plate guide rail 2133 and the pressure plate driving assembly, wherein the pressure plate 2132 is slidably connected to the pressure plate guide rail 2133, and the pressure plate driving assembly is used to drive the pressure plate 2132 to move up and down along the pressure plate guide rail 2133. Specifically, the pressure plate guide rail 2133 can be installed on the material loading support column 212, and the pressure plate guide rail 2133 is slidably connected to the pressure plate guide rail 2133 through a slider.

[0142] It can be understood that the pad 2131 in the present invention can also achieve the compression and loosening of the crystal rod by moving up and down. Therefore, the material loading and clamping device 213 of the embodiment of the present invention can also include a vertically arranged pad guide rail and a pad drive assembly not shown in the accompanying drawings. The pad 2131 is slidably connected to the pad guide rail to achieve the up and down movement of the pad 2131 on the pad guide rail. The pad drive assembly is used to drive the pad 2131 to move up and down along the pad guide rail. Specifically, the pad 2131 is slidably connected to the pad guide rail through a slider. The pad guide rail can be set on the material loading support column 212 together with the pressure plate guide rail 2133, or a pad support column can be set separately to support the pad 2131.

[0143] Furthermore, the pressing plate driving assembly is a pressing plate clamping cylinder 2134, the cylinder housing of the pressing plate clamping cylinder 2134 is fixedly connected to the material loading support column 212, and the movable end of the pressing plate clamping cylinder 2134 is connected to the pressing plate 2132. When the movable end of the pressing plate clamping cylinder 2134 is extended, the pressing plate 2132 is driven to move upward, and when the movable end of the pressing plate clamping cylinder 2134 is retracted, the pressing plate 2132 is driven to move downward. Of course, the pressing plate 2132 of the embodiment of the present invention can also be controlled to move up and down by other pressing plate driving assemblies. In addition, it should be noted that the embodiment of the present invention can also control the up and down movement of the pressing plate 2132 by other vertical moving assemblies, such as ball screws, etc. The relevant settings of the driving assembly of the pad 2131 can refer to the pad driving assembly.

[0144] The electrical and gas-consuming equipment on the rotating loading unit 21 of the embodiment of the present invention is powered by the electrical unit 22, for example, providing a pneumatic path for the pressure plate clamping cylinder 2134 of the loading clamping device 213, and providing a power path for the crystal rod detection device of the loading clamping device 213.

[0145] Furthermore, one end of the electrical fixing part 221 in the present invention is connected to the external fixing device, and the other end is fixedly connected to the slip ring assembly fixing part, which is used to fix the position of the slip ring assembly in the rotating material loading unit 21. That is, the external energy input device and the electrical circuit and the electrical structure of the rotating material loading unit 21 are always in a fixed position to improve the stability of the equipment operation.

[0146] Furthermore, in the slip ring assembly of the present invention, a slip ring air inlet is provided at the slip ring fixed part, and a slip ring air outlet is provided at the slip ring rotating part. The slip ring air inlet and the slip ring air outlet are provided correspondingly to realize uninterrupted air supply to the gas-consuming equipment of the rotating material loading unit 21, and the slip ring rotating part can rotate relative to the slip ring fixed part. In addition, the slip ring assembly of the embodiment of the present invention also includes an electric input interface provided at the slip ring fixed part and an electric output interface provided at the slip ring rotating part. The electric input interface and the electric output interface are provided correspondingly to realize uninterrupted power supply to the electric equipment of the rotating material loading unit 21.

[0147] Furthermore, the electrical rotating part 222 of the electrical unit 22 in the present invention includes a wiring pipe fixedly connected to the rotating material loading unit 21, the wiring pipe is fixedly connected to the slip ring rotating part, and the electrical lines connected from the slip ring rotating part are connected to various electrical devices on the rotating material loading unit 21 through the wiring pipe. Since the wiring pipe and the rotating material loading unit 21 are in a relatively static state, the gas pipeline and the electrical line on the wiring pipe will not cause the line entanglement problem as the rotating material loading unit 21 rotates.

[0148] Further, the wiring pipe in the present invention includes a vertical pipeline 2221 and a horizontal pipeline 2222, wherein one end of the vertical pipeline 2221 is connected to the rotating part of the slip ring assembly, and the other end is fixedly connected to the rotating material loading unit 21. Specifically, the vertical pipeline 2221 is connected to the rotating disk 211 of the rotating material loading unit 21, and the vertical pipeline 2221 can rotate with the rotating disk 211, and provide vertical support for the slip ring assembly and the horizontal pipeline 2222.

[0149] Furthermore, one end of the horizontal pipeline 2222 is fixedly connected to the vertical pipeline 2221 , and the other end of the horizontal pipeline 2222 is fixedly connected to the rotating loading unit 21 , and the electrical circuit is connected to the electrical equipment on the rotating loading unit 21 through the horizontal pipeline 2222 .

[0150] In a specific embodiment of the present invention, since there are water stains on the crystal rod clamped by the rotating loading unit 21, the rotation of the rotating loading unit 21 further accelerates the throwing out of the water stains on the crystal rod. Therefore, the present invention arranges a water receiving unit 23 (hereinafter referred to as the water receiving unit) to receive the water stains dripping from the crystal rod.

[0151] The water receiving unit 23 in the present invention includes a water receiving tray, which is arranged below the rotating loading unit 21 of the rotating loading platform 2. A rotating drive unit 24 is arranged below the water receiving tray. The water receiving tray is used to receive water stains flowing down from the rotating loading unit 21 to prevent the water stains from splashing onto the rotating drive unit 24.

[0152] Furthermore, the water receiving tray in the present invention includes a connecting shaft through hole, through which the connecting assembly between the rotating material loading unit 21 and the rotating driving unit 24 passes. A drain port is also provided on the water receiving tray, and a water receiving pipe is connected below the drain port. The drain port is used to discharge the water in the water receiving tray through the drain port. At the same time, water receiving tray ribs are also provided on the four edges of the water receiving tray to prevent the water in the water receiving tray from flowing out through the four edges of the water receiving tray.

[0153] Furthermore, the water receiving tray 231 is provided with a clamping cylinder through hole for the clamping cylinder on the rotating material loading unit 21 to pass through. Due to the up and down movement of the pressing plate 2132 of the material loading clamping device 213, the bottom end surface of the pressing plate clamping cylinder 2134 may pass through the water receiving tray. At this time, the water receiving tray is also provided with a pressing plate clamping cylinder through hole for the pressing plate clamping cylinder 2134 to pass through. It can be understood that the clamping cylinder through hole is provided with a clamping cylinder through hole water retaining edge around the periphery to prevent water from flowing out through the clamping cylinder through hole.

[0154] Furthermore, the water receiving tray 231 is fixedly connected to the rotating material loading unit 21, and rotates together with the rotating material loading unit 21 under the drive of the rotating driving unit 24. Since the pressure plate clamping cylinder 2134 on the rotating material loading unit 21 rotates with the rotating material loading unit 21, the water receiving tray 231 rotates together with the rotating material loading unit 21 in the present invention, so that the pressure plate clamping cylinder 2134 and the water receiving tray 231 are relatively stationary, so that there is no interference between the water receiving tray 231 and the pressure plate clamping cylinder 2134.

[0155] Furthermore, the outer contour of the water receiving tray 231 in the horizontal direction is larger than the outer contour of the rotating loading unit 21 projected onto the horizontal plane, so that all the water stains flowing down from the rotating loading unit 21 can be received by the water receiving tray.

The positioning base plate 112 and the clamping block 113 can clamp the crystal rod in the vertical direction.

[0159] Furthermore, rubber-coated rollers 114 are provided on both sides of the material platform base 111, and the crystal rod is placed on them, so that the crystal rod can slide on it without hindrance; baffles 115 are also provided on both sides of the material platform base 111, and the baffles 115 are used to prevent the silicon rod from falling from both sides.

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.

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.

[0163] 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.

[0164] As a preferred embodiment, the cutting unit of the crystal rod cutting system of the present invention 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.

[0165] Specifically, Figure 26 to Figure 29 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.

[0166] Specifically, Fig.29 and Fig.30As 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] like Fig.30 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.

[0171] like Figure 31 to Figure 33 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.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] 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.

[0176] Specifically, Figure 26 to Figure 28 , Figure 34 to Figure 37 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.

[0177] 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 structures of the first head 431 and the second head 432 are basically the same. Specifically, the first head 431 includes a head frame 433, on which a driving wheel assembly 434, a tension wheel assembly 435 and a driven wheel assembly 436 are provided. The driving wheel assembly 434, the tension wheel assembly 435 and the driven wheel assembly 436 are arranged in a ring shape, and an annular cutting tool (not shown in the figure) is provided on the outside; the driving wheel assembly 434 can drive the annular cutting tool to rotate at high speed to generate cutting force, and the tension wheel assembly 435 can adjust the position of the rotation axis to adjust the tension of the annular cutting tool. 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.

[0178] 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.

[0179] like Fig.34As 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.

[0180] 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.

[0181] The second head 432 has a substantially identical structure to the first head 431. To further improve the processing efficiency, Fig.35 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.34 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.

[0182] The driving wheel assembly 434 of the first head 431 and the second head 432 is preferably as follows Fig.34The 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.

[0183] 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.

[0184] like Fig.34 As 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.

[0185] 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.36 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.

[0186] Further, if Figure 37 to Figure 39As 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.

[0187] Specifically, Fig.38 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.

[0188] Further, if Fig.35 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.

[0189] 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.

[0190] The above cutting space can be used for half-rod cutting of the crystal rod, such as Fig.47As 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] like Fig.24 and Fig.25As 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.

[0195] 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.

[0196] like Fig.40 and Fig.41 As 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.

[0197] 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.

[0198] 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.

[0199] 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.

[0200] 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.

[0201] Specifically, Figure 1 and Figure 2As shown, the extension direction of the first head assembly and the second head 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, and in the vertical direction, the direction perpendicular to the first direction X is defined as a third direction Z.

[0202] like Figures 1 to 3 , Figure 42 to Figure 44 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.

[0203] 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.

[0204] 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.

[0205] 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.

[0206] 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.

[0207] 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.

[0208] 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.

[0209] like Fig.43 As 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.

[0210] Further, if Fig.48As 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.

[0211] 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.49 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.

[0212] The edge material unloading device 5 of the present invention can be as follows Fig.48 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.

[0213] 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:

[0214] 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.

[0215] Specifically, Figure 1 and Fig.44 As 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.

[0216] 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.

[0217] 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.

[0218] 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.

[0219] 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.

[0220] 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:

[0221] like Fig.45 As shown, L1 is the clamping path of the clamping jaws entering the machine head, and L2 is the unloading path of the clamping jaws moving out of the machine head. The clamping jaws first move to the outside of the machine head along the first direction X, and then move along the second direction Y, pass through the machine head frame 433, and clamp the edge skin; after the clamping jaws clamp the edge skin, they first move 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 they move 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 mutually staggered in the second direction Y; finally, they move along the first direction X toward the opening 437 of the machine head frame 433 until they are moved 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; in addition, when a support frame is provided at the single-side opening structure of the machine head frame 433, this unloading method can also make the edge skin and the support frame staggered to avoid interference.

[0222] 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.

[0223] 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.

[0224] 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.

[0225] 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.

[0226] 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 first cutting chamber and the second cutting chamber at a side away from the feeding assembly, and respectively cooperate with the first shavings unloading assembly and the second shavings unloading assembly to receive the shavings unloaded by the first shavings unloading assembly and the second shavings unloading assembly, so as 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.

[0227] Based on the above description of the specific structure of the crystal ingot cutting system, the working process and cutting method of the crystal ingot cutting system are further described in detail below.

[0228] First, the turning table 1 in the present invention loads materials onto the rotating loading table 2, and the specific steps are as follows:

[0229] Step 1: After the loading and unloading platform 11 of the turning table 1 clamps the crystal ingot to be processed, the turning table 1 is controlled to move toward the rotating loading platform 2 as a whole;

[0230] Step 2: Control the loading and unloading platform 11 to flip to a vertical position and then move to the crystal rod clamping station on the rotating loading platform 2;

[0231] Step 3: When the crystal ingot clamped by the loading and unloading platform 11 is transported to the top of the pad 2131 of the loading and clamping device 213, the positioning base plate 112 and the clamping block 113 of the loading and unloading platform 11 are controlled to move downward simultaneously so that the positioning base plate 112 and the pad 2131 of the loading and clamping device 213 are in the same plane;

[0232] Step 4: Control the pressing plate 2132 of the material loading and clamping device 213 to move downward until it contacts the upper end surface of the crystal ingot to clamp the crystal ingot;

[0233] Step 5: Control the positioning base plate 112 of the loading and unloading platform 11 to release the clamping block 113 while continuing to move downward;

[0234] Step 6: Control the loading and unloading platform 11 to withdraw from the second crystal rod loading and unloading station and flip to a horizontal position.

[0235] The above steps can complete the transfer of the crystal rod between the turning table 1 and the rotating material carrier 2. It can be understood that the operation process of the turning table 1 taking the crystal rod from the material carrier clamping device 213 can also be reversed, which will not be described in detail in the present invention.

[0236] Then, the rotating loading platform 2 and the crystal rod transfer device 3 cooperate with each other to realize the loading and unloading process of the crystal rod in each cutting chamber. The specific steps are as follows:

[0237] Step 1: The rotary clamping unit 31 is driven by the transfer translation unit 32 to translate to the vicinity of the rotary loading platform 2;

[0238] Step 2: Control the rotary clamping unit 31 to rotate so that the first crystal ingot clamping claw assembly 312 turns to the direction of the rotating loading platform 2 (at this time, the rotating loading platform 2 has rotated the crystal ingot clamping station holding the crystal ingot to be processed to a position corresponding to the rotary clamping device) until the first crystal ingot clamping claw assembly reaches the crystal ingot clamping position;

[0239] Step 3: The upper clamping jaw module 3121 of the first crystal ingot clamping jaw assembly 312 is controlled to move up and down to adjust the distance between the upper clamping jaw module 3121 and the lower clamping jaw module 3122 to adapt to the length of the crystal ingot to be processed;

[0240] Step 4: After the clamping jaws of the first crystal ingot clamping jaw assembly 312 move to clamp the crystal ingot to be processed, the pressing plate 2132 of the rotating loading platform 2 moves upward to release the crystal ingot to be processed;

[0241] Step 5: Control the upper clamping jaw module 3121 and the lower clamping jaw module 3122 of the crystal ingot clamping jaw assembly 312 to move upward simultaneously, so that the crystal ingot to be processed leaves the crystal ingot clamping station of the rotating loading platform 2;

[0242] Step 6: Control the second crystal rod clamping claw assembly 314 of the rotary clamping unit 31 to rotate toward the direction of the cutting chamber, and translate to the first cutting chamber under the drive of the transfer translation unit 32;

[0243] Step 7: First, control the second crystal ingot clamping claw assembly 314 to clamp the processed crystal ingot on the cutting station in the first cutting chamber, and lift the clamping claw of the second crystal ingot clamping claw assembly 314 to make the processed crystal ingot leave the cutting station;

[0244] Step 8: Control the rotary clamping unit 31 to rotate, so that the first crystal rod clamping claw assembly 312 holding the crystal rod to be processed rotates toward the cutting station, and places the crystal rod to be processed on the cutting station. After the cutting station stably clamps the crystal rod to be processed, control the transfer translation unit 32 to drive the rotary clamping unit 31 to exit the first cutting chamber;

[0245] Step 9: Driven by the transfer translation unit 32, the rotary clamping unit 31 is translated to the vicinity of the rotating loading platform 2, and the rotary clamping unit 31 is controlled to rotate so that the second crystal rod clamping assembly 314 turns to the rotating loading platform 2, and the second crystal rod clamping assembly 314 is controlled to place the clamped processed crystal rod at the crystal rod clamping station of the rotating loading platform 2. After the loading clamping device 213 of the rotating loading platform 2 stably clamps the crystal rod to be processed, the loading and unloading of the crystal rod is completed.

[0246] Step 10: When two or more cutting stations are provided in the first cutting chamber, repeat steps 1 to 9 to perform loading and unloading operations on all cutting stations in the first cutting chamber;

[0247] Step 11: After the first cutting chamber completes loading and unloading, the rotary clamping unit 31 exits the first cutting chamber driven by the transfer translation unit 32, and the first cutting chamber starts the crystal rod cutting operation. At the same time, the transfer translation unit 32 drives the rotary clamping unit 31 to translate again to the vicinity of the rotating loading platform 2;

[0248] Step 12: Repeat steps 2 to 5, then control the second crystal rod clamping claw assembly 314 of the rotary clamping unit 31 to rotate toward the direction of the cutting chamber, and translate to the second cutting chamber under the drive of the transfer translation unit 32, and then repeat steps 7 to 9 to complete the loading and unloading of the cutting station in the second cutting chamber.

[0249] In combination with the above operating steps, through the cooperation of the rotating loading table 2 and the crystal rod transfer device 3, the loading and unloading of the crystal rod can be carried out simultaneously in one loading and unloading translation movement, thereby reducing the time beat of loading and unloading. At the same time, two or more independently working cutting rooms can share a set of rotating loading table 2 and crystal rod transfer device 3 for loading and unloading, further shortening the time beat of cutting crystal rods and loading and unloading between each cutting room, thereby greatly improving the processing efficiency.

[0250] Third, after the cutting chamber completes the above-mentioned crystal rod cutting process, it is also necessary to unload the cut edge skin through the edge skin material unloading device 5. For example, two cutting stations are arranged between a group of machine heads. The two cutting stations are arranged side by side along the extension direction of the first machine head assembly and the second machine head assembly. The one far away from the opening 437 of the machine head frame 433 is the first cutting station, and the one close to the opening 437 of the machine head frame 433 is the second cutting station. The specific steps of unloading the edge skin are as follows:

[0251] Step 1, the head assembly 43 moves from top to bottom, and after completing the cutting of the two crystal bars at the first cutting station and the second cutting station, 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 at the first cutting station in the second direction Y;

[0252] Step 2, 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;

[0253] 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;

[0254] Step 4: After the edge skin and the crystal rod are slid and separated, the two clamping jaws 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;

[0255] 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.

[0256] 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;

[0257] 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;

[0258] Step 8: 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;

[0259] Step 9, 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;

[0260] Step 10, 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.

[0261] In summary, the ingot cutting system of the present invention has the following advantages:

[0262] 1.
