[0051] The present utility model also provides a wire cutting machine, which includes any one of the above clamping devices.

[0052] In the clamping device and the wire cutting machine of the present utility model, there are two crystal holders capable of adapting to the bonding of semi - rods, and a clamping table, which enables the crystal bar to be installed on an existing wire cutting machine. When the wire cutting machine cuts, the whole crystal bar is cut simultaneously, which is beneficial to making use of the cutting ability of the existing wire cutting machine.

[0053] Specifically, when the clamping device of the present utility model installs a semi - rod, each crystal holder installs one semi - rod, and there are no problems such as interference and extrusion, and the installation difficulty is low. Obviously, two semi - rods can be cut simultaneously. Compared with cutting two semi - rods separately in batches, it is beneficial to improve the cutting efficiency of semi - slice cutting; and the slicing machine slices two semi - rods simultaneously, which is beneficial to adapting to the cutting ability and cutting process of the slicing machine. On the other hand, when discharging after slicing, the two crystal holders can be separated, that is, the slices on the crystal holders are separated, which is beneficial to obtaining the slices. That is, before degumming, the two crystal holders are separated, and each semi - rod is adhered to a separate crystal holder, so that the subsequent processes of de - inserting and washing can be automated. Obviously, the clamping device of the present utility model provides technical support for conveniently obtaining smaller slices.

[0054] Particularly, in the clamping device and the wire cutting machine of the present utility model, due to the presence of a locking unit, a firm fixation between the clamping table and the crystal holder can be achieved, forming a stable overall structure. When installing the clamping table, the overall structure can be quickly installed. Specifically, when positioning and clamping the overall structure, since a stable overall structure has been formed, after any component is stably clamped, the whole is also stably clamped. For example, after the clamping table is stably installed, the crystal holder is naturally stably clamped, which is beneficial to improving the installation speed.

[0055] Of course, the locking unit can work after, before or during the clamping of the clamping table, which is beneficial to improving the clamping flexibility, but does not affect the final clamping effect.

[0056] Furthermore, in the clamping device and the wire cutting machine of the present utility model, since there is a clamping table, it is not necessary to improve the existing clamping seat. To put it another way, even if it is necessary to improve the existing clamping seat, the improvement is relatively small, which is beneficial to reducing costs.

[0057] Specifically, during use, after the crystal carrier is installed on the clamping table, the assembly composed of the crystal carrier and the clamping table is then installed on the clamping seat, which facilitates the transportation and installation of the crystal bar. Moreover, the clamping seat can directly utilize the clamping seat in the existing wire cutting machine. That is to say, during the production and manufacturing process of the clamping device of the present invention, based on the existing clamping device, the clamping seat therein does not need to be redesigned or significantly modified, which is conducive to cost reduction.

[0058] Furthermore, in the clamping device and the wire cutting machine of the present invention, due to the presence of the third installation groove, namely the clamping table installation groove, which is used to prevent the clamping table from disengaging downward from the clamping seat. The clamping table installation groove is horizontally arranged, and at least one end of the clamping table installation groove penetrates through the clamping seat. Of course, in some alternative embodiments, the clamping table installation groove only facilitates the installation of the clamping table, and the lifting unit is used to prevent the clamping table from disengaging downward from the clamping seat.

[0078] As Figure 1 shown, and with reference to Figures 2 to 6, an embodiment of the present utility model provides a clamping device, which includes a clamping table 10, a first crystal carrier 21, a second crystal carrier 22, and a locking unit 50. The clamping table 10 has a first installation groove 11 and a second installation groove 12. The first crystal carrier 21 is disposed on the lower side of the clamping table 10, and a first clamping block 25 is provided on the upper side of the first crystal carrier 21. The first clamping block 25 is installed in the first installation groove 11. The second crystal carrier 22 is disposed on the lower side of the clamping table 10, and the second crystal carrier 22 is arranged parallel to the first crystal carrier 21. A second clamping block 26 is provided on the upper side of the second crystal carrier 22. The second clamping block 26 is installed in the second installation groove 12. The locking unit 50 is disposed on the clamping table 10, and the locking unit 50 is configured to urge the first clamping block 25 to move downward relative to the clamping table 10 and urge the second clamping block 26 to move downward relative to the clamping table 10.

[0079] When the clamping device of the embodiment of the present utility model is in use, the first crystal carrier 21 and the second crystal carrier 22 can be first installed on the clamping table 10, and then the whole formed by the clamping table 10, the first crystal carrier 21, and the second crystal carrier 22 is installed on a wire cutting machine. The locking unit 50 can work after, before, or during the clamping of the clamping table 10, so that the first crystal carrier 21 and the second crystal carrier 22 are stably clamped, and then the cutting device of the wire cutting machine is used for cutting. In some alternative embodiments, the clamping table 10 can also be fixedly arranged on the wire cutting machine, and then the first crystal carrier 21 and the second crystal carrier 22 are respectively installed on the clamping table 10. The locking unit 50 works to stably clamp the first crystal carrier 21 and the second crystal carrier 22, and then the cutting device is used for cutting. At the same time, the reverse operation can also realize the disassembly of the crystal carrier, that is, on a working platform, the functions of clamping, fastening, and disassembling of a half-piece double crystal bar can be realized.

[0080] The clamping device of the embodiment of the present utility model has two crystal carriers, namely the first crystal carrier 21 and the second crystal carrier 22. The crystal carriers are both half-piece crystal carriers that can be adapted to the bonding of half rods, that is, a half rod can be installed on the lower side of each crystal carrier. In this way, it is equivalent to clamping a crystal bar, and there is a clamping table 10, which can enable the crystal bar to be installed on an existing wire cutting machine. When the wire cutting machine cuts, the whole crystal bar is cut at the same time, which is beneficial to utilizing the cutting ability of the existing wire cutting machine.

[0081] Specifically, when installing the half rods on the clamping device, each crystal carrier installs one half rod, and there are no problems such as interference and extrusion, and the installation difficulty is low. The slicing machine can cut two half rods at the same time, and the cutting ability can be effectively exerted, which can reduce the cost. After slicing, the two crystal carriers can be separated to realize blanking, and the automatic degumming operation can be carried out on the slices on the two crystal carriers respectively, which is beneficial to the acquisition of the obtained slices. Obviously, the clamping device of the embodiment of the present utility model provides technical support for conveniently obtaining smaller slices.

[0082] In particular, in the clamping device according to the embodiment of the present utility model, due to the presence of the locking unit 50, a firm fixation between the clamping table 10 and the crystal carrier can be achieved, forming a stable overall structure. When installing the clamping table 10, the overall structure can be quickly installed. Specifically, when positioning and clamping the overall structure, since a stable overall structure has been formed, after any component is stably clamped, the overall structure is also stably clamped. For example, after the clamping table 10 is stably installed, the crystal carrier is naturally stably clamped, which is beneficial to improving the installation speed. Of course, the locking unit 50 can work after, before or during the clamping of the clamping table 10, which is beneficial to improving the clamping flexibility, but does not affect the final clamping effect.

[0083] In some embodiments of the present utility model, the first crystal carrier 21 contacts the second crystal carrier 22, and the lower surface of the first crystal carrier 21 is flush with or has a very small height difference from the lower surface of the second crystal carrier 22, and the height difference is less than 5 mm. Such a setting is beneficial to forming an integral body of the two half rods on the first crystal carrier 21 and the second crystal carrier 22, which is beneficial to the cutting device to cut the crystal bar simultaneously or with a small time difference. In other embodiments of the present utility model, according to the actual working conditions, the first crystal carrier 21 and the second crystal carrier 22 can be arranged at intervals, and the distance between the first crystal carrier 21 and the second crystal carrier 22 should be less than or equal to 15 mm. For example, the distance between the first crystal carrier 21 and the second crystal carrier 22 is 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 8 mm, 10 mm, 11 mm, 12 mm or 13 mm, etc.

[0084] In some embodiments of the present utility model, both the first crystal carrier 21 and the second crystal carrier 22 are semi - sheet - type crystal carriers, so that the lower sides of the first crystal carrier 21 and the second crystal carrier 22 are respectively installed with half rods. Such a setting enables the cutting device to cut the two half rods simultaneously, and it is easy to obtain smaller slices after cutting.

[0085] It should also be noted here that in the photovoltaic industry, a half rod is not exactly half of a square rod, not half in the geometric sense. For example, for a square rod of 180×180, the corresponding half - rod specifications may be 180×89, 180×90, 180×91, etc. That is to say, the half rod can be larger than or smaller than half of the square rod in the geometric sense, that is, the relationship between the length and width of the cross - section of the half rod can be: the width of the cross - section of the half rod is between half of the length of the cross - section minus a preset difference and half of the length of the cross - section plus a preset difference, and the preset difference can be 1 / 10 of the length of the cross - section of the half rod, etc. Generally, the two half rods carried by the first crystal carrier 21 and the second crystal carrier 22 can form a complete square rod. In the actual production and manufacturing process, the two half rods carried by the first crystal carrier 21 and the second crystal carrier 22 can be both larger than or smaller than or equal to half of the square rod in the geometric sense.

[0086] In some alternative embodiments of the present utility model, the sizes of the first crystal carrier 21 and the second crystal carrier 22 can be set according to actual requirements. For example, crystal bars are respectively installed on the lower sides of the first crystal carrier 21 and the second crystal carrier 22. In some other alternative embodiments of the present utility model, the lower surface of the first crystal carrier 21 can also be smaller than or larger than the lower surface of the second crystal carrier 22.

[0087] In some embodiments of the present utility model, the first installation groove 11 is used to prevent the first clamping block 25 from disengaging downward from the clamping table 10. The second installation groove 12 is used to prevent the second clamping block 26 from disengaging downward from the clamping table 10. Such a setting is beneficial to protecting the crystal bars, semi-crystal bars, etc. on the first crystal carrier 21 and the second crystal carrier 22, and is also beneficial to the transportation of crystal bars, semi-crystal bars, etc.

[0088] In some embodiments of the present utility model, as Figures 1 to 3 shown, the locking unit 50 includes a first telescopic assembly 51 and a second telescopic assembly 52. The first telescopic assembly 51 is disposed on the clamping table 10 and is located above the first installation groove 11. The output shaft of the first telescopic assembly 51 is vertically arranged, and the lower end of the output shaft of the first telescopic assembly 51 is configured to contact the first clamping block 25.

In this embodiment, the locking unit 50 can be a telescopic assembly, which is convenient to control and firmly fixed.

[0089] In some other embodiments of the present utility model, as Figures 4 to 6 shown, the locking unit 50 includes a first pressing block 53, a second pressing block 54 and an adjusting assembly. The first pressing block 53 is movably disposed up and down on the clamping table 10 and is located above the first installation groove 11. The first pressing block 53 is configured to contact the first clamping block 25. The second pressing block 54 is movably disposed up and down on the clamping table 10 and is located above the second installation groove 12. The second pressing block 54 is configured to contact the second clamping block 26. The adjusting assembly is installed on the clamping table 10 and is configured to adjust the height of the first pressing block 53 relative to the clamping table 10 and adjust the height of the second pressing block 54 relative to the clamping table 10. Further, the adjusting assembly can be driven manually by a worker or by using a tool.

[0090] Preferably, both the first pressing block 53 and the second pressing block 54 have a first inclined surface facing obliquely upward. That is, the first pressing block 53 and the second pressing block 54 are wedge-shaped blocks. The adjusting assembly includes: a first adjusting assembly configured to adjust the height of the first pressing block 53 relative to the clamping table 10; a second adjusting assembly configured to adjust the height of the second pressing block 54 relative to the clamping table 10.

The pressing block 55 is disposed on the clamping table 10 so as to move in the horizontal direction, and a second inclined surface in contact with the first inclined surface is provided on the pressing block 55. The adjusting rod 56 extends in the horizontal direction and is threadedly connected to the clamping table 10. The adjusting rod 56 is in contact with the pressing block 55, or the adjusting rod 56 is rotatably connected to the pressing block 55. The reset element 57 is disposed on the clamping table 10 and configured to urge the corresponding first pressing block 53 or second pressing block 54 to move upward.

[0093] In some embodiments of the present utility model, the clamping table 10 includes a clamping table body 14 and two adjusting brackets 15. The clamping table body 14 has a first mounting groove 11 and a second mounting groove 12; the clamping table body 14 further has an adjusting hole 16 on the upper side of the first mounting groove 11 and the second mounting groove 12; the adjusting hole 16 penetrates the clamping table body 14. The two adjusting brackets 15 are respectively installed at both ends of the adjusting hole; each pressing block 55 is installed on one adjusting bracket 15 and is located in the adjusting hole 16; each adjusting rod 56 is threadedly connected to one adjusting bracket 15; an adjusting block is provided at the outer end of each adjusting rod 56. By providing the clamping table body 14 and the adjusting brackets 15, it is beneficial to the production and manufacture of the clamping device.

[0094] In some embodiments of the present utility model, such as Figure 3 and Figure 6As shown, the clamping device further includes a clamping seat 30 and a lifting unit 40 mounted on the clamping seat 30. The lifting unit 40 is configured to drive the clamping table 10 to move upward, or the lifting unit 40 is configured to drive the first crystal carrier 21 and the second crystal carrier 22 to move upward. The clamping seat 30 is used to define the upward movement stroke of the first crystal carrier 21 and the second crystal carrier 22 relative to the clamping seat 30, or to define the upward movement stroke of the first crystal carrier 21 and the second crystal carrier 22 relative to the clamping seat 30.

[0095] When clamping, the lifting unit 40 drives the clamping table 10 or drives the first crystal carrier 21 and the second crystal carrier 22 to move upward. After the clamping table 10 or the first crystal carrier 21 and the second crystal carrier 22 are blocked by the clamping seat 30, the clamping of the clamping table 10, the first crystal carrier 21 and the second crystal carrier 22 is achieved.

[0096] In this embodiment, since there is a clamping table 10, it is not necessary to improve the existing clamping seat 30. Further, even if it is necessary to improve the existing clamping seat 30, the improvement is relatively small, which is beneficial to reducing costs. Specifically, in use, after the crystal carrier is installed on the clamping table 10, the whole formed by the crystal carrier and the clamping table 10 is then installed on the clamping seat 30, which is convenient for the transfer and installation of the crystal bar. Moreover, the clamping seat 30 can directly utilize the clamping seat 30 in the existing wire cutting machine. That is to say, during the production and manufacturing process of the clamping device of the present invention, based on the existing clamping device, the clamping seat 30 therein does not need to be redesigned or relatively large modifications are not required, which is beneficial to reducing costs.

[0097] For example, in some embodiments of the present invention, the clamping device further includes a lifting block 41. The clamping table 10 further has a receiving groove 13, and the receiving groove 13 is between the first installation groove 11 and the second installation groove 12. The lifting block 41 is disposed in the receiving groove 13 and is configured to drive the clamping table 10 to rise by contacting the clamping table 10. The lifting unit 40 is configured to drive the lifting block 41 to move upward.

[0098] In some alternative embodiments of the present invention, the clamping device further includes a lifting frame. A fourth installation groove is provided on the lifting frame, and the clamping table 10 is installed in the fourth installation groove. The lifting unit 40 is configured to drive the lifting frame to move upward. In this embodiment, there may be two lifting frames, which are disposed at both ends of the clamping seat 30.

[0099] In some embodiments of the present invention, the lifting unit 40 can drive the crystal carrier to move upward outside both ends of the clamping seat 30. Further, hanging grooves are provided at both ends of the first crystal carrier 21, and hanging grooves are provided at both ends of the second crystal carrier 22. The lifting unit 40 includes a hook, and the hook is inserted into the hanging groove to drive the first crystal carrier 21 and the second crystal carrier 22 to rise.

[0100] In some embodiments of the present utility model, the clamping table 10 is movably mounted on the clamping seat 30 in the up-and-down direction. Further, after the clamping table 10 is mounted on the clamping seat 30, it cannot be disengaged from the clamping seat 30 and can only move up and down relative to the clamping seat 30. When transporting the ingot and semi-ingot, it is the transportation of each crystal carrier and the ingot bonded to the crystal carrier, rather than the transportation of the whole formed by the crystal carrier and the clamping table 10.

[0101] In some alternative embodiments, after the clamping table 10 is mounted on the clamping seat 30, it can be disengaged from the clamping seat 30. For example, as Figure 7 and Figure 8 shown, the clamping seat 30 has a third mounting groove 31, and the clamping table 10 is mounted in the third mounting groove 31. In use, after the crystal carrier is mounted on the clamping table 10, then the whole formed by the crystal carrier and the clamping table 10 is mounted on the clamping seat 30, which is convenient for the transportation and installation of the ingot. Moreover, the clamping seat 30 can directly utilize the clamping seat 30 in the existing wire cutting machine. That is to say, during the production and manufacturing process of the clamping device in the embodiment of the present utility model, based on the existing clamping device, the clamping seat 30 therein does not need to be redesigned or greatly modified, which is beneficial to reducing costs. Further, the third mounting groove 31 is used to prevent the clamping table 10 from disengaging downward from the clamping seat 30. The third mounting groove 31 is horizontally arranged, and at least one end of the third mounting groove 31 penetrates the clamping seat 30. Of course, in some alternative embodiments, the third mounting groove 31 only facilitates the installation of the clamping table 10, and the lifting unit is used to prevent the clamping table 10 from disengaging downward from the clamping seat 30.

[0102] In some embodiments of the present utility model, the clamping seat 30 has a first limiting surface, and the first crystal carrier 21 has a second limiting surface 211. The first limiting surface is configured to contact and abut against the second limiting surface 211 to limit the upward movement stroke of the first crystal carrier 21 relative to the clamping seat 30. The clamping seat 30 has a third limiting surface, and the second crystal carrier 22 has a fourth limiting surface 221. The third limiting surface is configured to contact and abut against the fourth limiting surface 221 to limit the upward movement stroke of the second crystal carrier 22 relative to the clamping seat 30. As Figure 7 shown, the first limiting surface and the third limiting surface are arranged on both sides of the third mounting groove 31. Such an arrangement can make the structure of the clamping device compact.

[0103] In some embodiments of the present utility model, as Figure 8As shown, the clamping device further includes a positioning component, which is disposed between the first crystal carrier 21 or the first clamping block 25 and the clamping seat 30 to define the upward movement stroke of the first crystal carrier 21 relative to the clamping seat 30, and / or is disposed between the second crystal carrier 22 or the second clamping block 26 and the clamping seat 30 to define the upward movement stroke of the second crystal carrier 22 relative to the clamping seat 30. A positioning component is disposed between the clamping seat 30 and the crystal carrier. The clamping seat 30 restricts the upward movement of the positioning component, and the positioning component restricts the upward movement of the crystal carrier, thereby realizing the function of the clamping seat 30 for defining the upward movement strokes of the first crystal carrier 21 and the second crystal carrier 22 relative to the clamping seat 30.

[0104] In some preferred embodiments of the present invention, the clamping table 10 has a first through hole on the upper side of the first installation groove 11. The positioning component includes a first positioning member 61, and the first positioning member 61 passes through the first through hole and contacts the upper surface of the first clamping block 25. The clamping table 10 has a second through hole on the upper side of the second installation groove 12. The positioning component includes a second positioning member 62, and the second positioning member 62 passes through the second through hole and contacts the upper surface of the second clamping block 26.

[0105] During operation, a crystal bar or a half crystal bar can be installed on the crystal carrier. Then, the crystal carrier is installed on the clamping table 10 through the installation groove for the crystal carrier. Then, the lifting unit 40 can directly drive the crystal carrier or drive the crystal carrier to move upward through the clamping table 10. As the crystal carrier moves upward, the positioning component acts on the crystal carrier and hinders the upward movement of the crystal carrier. At this time, the clamping of the crystal carrier is realized. That is, the clamping device of the embodiment of the present invention realizes the clamping of the crystal carrier by providing a through hole and a positioning component.

[0106] In the embodiment of the present invention, the surfaces of the positioning component for positioning, that is, the lower end surfaces of the first positioning member 61 and the second positioning member 62, are significantly smaller than the top surface of the crystal carrier installation groove. Correspondingly, the positioning surfaces corresponding to the upper surfaces of the clamping blocks on the crystal carrier, that is, the first clamping block and the second clamping block, are only a part of the upper surface of the clamping block. This can significantly reduce the processing surface. When processing a smaller processing surface, it is obviously beneficial to reduce the processing cost while improving the processing quality. Moreover, due to the high processing quality of the processing surface, that is, the high flatness of the processing surface, it is beneficial to improve the clamping effect. That is, the clamping device of the present invention has a lower cost and a higher clamping effect compared with the existing clamping devices.

[0107] Moreover, since the through hole is on the upper side of the crystal carrier installation groove, the positioning component contacts at least the middle part of the clamping block along the width direction of the clamping block, so that the middle part of the clamping block can be clamped, preventing the problem of crystal carrier deflection when clamping at the edge position of the crystal carrier, that is, preventing the crystal carrier from being higher on one side and lower on the other side. When clamping in the middle, compared with clamping on both sides of the crystal carrier, the processing cost can be reduced.

[0108] In particular, in the clamping device and the wire cutting machine of the present utility model, since there are two crystal carriers and the distance between the two crystal carriers is relatively close or they need to be in contact, it is impossible to clamp on both sides of each crystal carrier, that is, the problem of crystal carrier deflection cannot be solved. In view of this, the present utility model adopts a scheme of middle clamping with a perforation and a positioning component, which is beneficial to keeping the lower surfaces of the two crystal carriers in the same plane.

[0109] In some embodiments of the present utility model, the first positioning member 61 is fixedly connected to the clamping seat 30, or the first positioning member 61 is arranged on the clamping seat 30 or the clamping table 10 so as to be movable up and down, and the upper end of the first positioning member 61 is configured to contact the clamping seat 30. The second positioning member 62 is fixedly connected to the clamping seat 30, or the second positioning member 62 is arranged on the clamping seat 30 or the clamping table 10 so as to be movable up and down, and the upper end of the second positioning member 62 is configured to contact the clamping seat 30.

[0110] That is to say, in some embodiments of the present utility model, the positioning component is fixedly connected to the clamping seat 30. For example, the positioning component can be installed on the clamping seat 30, or the positioning component and the clamping seat 30 are integrally formed. It can also be said that a smaller clamping mating surface is provided on the clamping seat 30 to reduce costs.

[0111] In some other embodiments of the present utility model, the positioning component is arranged so as to be movable up and down, and the upper end of the positioning component is configured to contact the clamping seat 30. That is to say, the positioning component is arranged on the clamping seat 30 or the clamping table 10 so as to move up and down. Preferably, the positioning component is arranged on the clamping table 10 so as to be movable up and down. By setting the movable scheme, for example, directly placing the positioning member in the perforation, it is beneficial to the replacement of the positioning member and also beneficial to the installation of the clamping device.

[0112] In some embodiments of the present utility model, the perforation of the clamping table 10 has a movement position on the lower side of the positioning component. In particular, when the positioning component is arranged on the clamping seat 30, the position of the clamping table 10 is beneficial to the horizontal movement of the clamping table 10, that is, beneficial to the installation of the clamping table 10, and the positioning component can also guide the lifting of the clamping table 10. In this embodiment, the clamping table 10 needs to be arranged on the clamping seat 30 so as to be movable up and down.

[0113] In some embodiments of the present utility model, the clamping device further includes a reset unit, which is arranged between the clamping table 10 and the positioning assembly and configured to urge the lower end of the positioning assembly to remain above the crystal carrier mounting groove. For example, the reset unit can be a compression spring, which is sleeved on the corresponding positioning member. In the initial position, the lower end of the positioning assembly is above the crystal carrier mounting groove, that is, it is not in the crystal carrier mounting groove. In this way, when installing the crystal carrier, there is no obstruction to the installation of the clamping block, which is beneficial to improving the installation speed. In this embodiment, the clamping table 10 needs to be movably arranged up and down on the clamping seat 30.

[0114] In some alternative embodiments of the present utility model, the lower end of the positioning assembly can also extend into the crystal carrier mounting groove, as long as it does not prevent the installation of the clamping block. Even if the installation is a bit difficult, it is also an acceptable solution. The lower end of the positioning assembly can also be made to extend into the crystal carrier mounting groove by using the reset unit.

[0115] In some embodiments of the present utility model, the first positioning member 61 is directly placed in the first through hole, and the second positioning member 62 is directly placed in the second through hole. Specifically, after the crystal carrier is installed on the clamping table 10, the positioning assembly is directly placed in the through hole, and the lower end of the positioning assembly contacts the crystal carrier. After the crystal carrier or the clamping table 10 rises, until the upper end of the positioning assembly contacts the clamping seat 30.

[0116] In some embodiments of the present utility model, the positioning members, that is, the first positioning member 61 and the second positioning member 62, are limit posts or limit blocks, and the projection of the positioning member in the horizontal plane is circular, square, polygonal or plum blossom-shaped.

[0117] In some embodiments of the present utility model, there is no clamping seat 30 and lifting unit 40, that is, the clamping table 10 is directly arranged on the wire cutting machine. During use, two crystal carriers are directly installed on the clamping table 10. Then, when transporting the crystal bar and semi-bar, it is the transportation of each crystal carrier and the crystal bar adhered to the crystal carrier, rather than the transportation of the whole formed by the crystal carrier and the clamping table 10. In some other embodiments of the present utility model, there is no lifting unit 40, and there is a clamping seat 30. The clamping table 10 is fixedly installed on or integrally formed with the clamping seat 30.

[0118] In some embodiments of the present utility model, the first mounting groove 11 is horizontally arranged, and at least one end of the first mounting groove 11 penetrates the clamping table 10. The second mounting groove 12 is horizontally arranged, and at least one end of the second mounting groove 12 penetrates the clamping table 10. The penetration of the mounting groove of the crystal carrier through the clamping table 10 is beneficial to the installation of the crystal carrier.

[0119] In some embodiments of the present utility model, a first guiding post is provided on the top wall of the first mounting groove 11, a first guiding groove is provided on the top wall of the first clamping block 25, and the first guiding post is inserted into the first guiding groove. A first wheel for supporting the first clamping block 25 is provided on the groove wall of the first mounting groove 11. A second guiding post is provided on the top wall of the second mounting groove 12, a second guiding groove is provided on the top wall of the second clamping block 26, and the second guiding post is inserted into the second guiding groove. A second wheel for supporting the second clamping block 26 is provided on the groove wall of the second mounting groove 12. In this embodiment, due to the presence of the guiding posts, guiding grooves and wheels, it is beneficial to improve the installation accuracy of the crystal carrier and the installation speed of the crystal carrier.

[0120] In some embodiments of the present utility model, the first mounting groove 11, the second mounting groove 12, the third mounting groove 31, and the accommodating groove 13 can all be T-shaped grooves, dovetail grooves or reverse dovetail grooves, etc. The lifting unit 40 can be a hydraulic cylinder, etc.

[0121] The embodiment of the present utility model also provides a wire cutting machine, which includes a cutting device and the clamping device in any of the above embodiments. The wire cutting machine is a cutting device for cutting hard and brittle material rods such as single crystal silicon material rods, polycrystalline silicon material rods, sapphire rods, and magnetic material rods. The wire cutting machine has the advantages of high efficiency, high productivity, high precision, etc. Its principle is to friction the workpiece to be processed through a cutting wire moving at a high speed, so as to achieve the purpose of cutting. The wire cutting machine often uses single-wire, multi-wire diamond wires, etc. to cut silicon materials, etc. for truncation, squaring, and slicing, so as to obtain corresponding silicon wafers or silicon materials. In this embodiment, the workpiece, such as a crystal rod, a half crystal rod, or two half crystal rods, is fixed by using the clamping device, and the cutting device moves the cutting wire thereon to cut the workpiece.

[0122] In some embodiments of the present utility model, the wire cutting machine is a slicing machine. Silicon rods, etc. can be sliced. For example, crystalline silicon is the main raw material of solar panels. Crystalline silicon needs to go through processes such as squaring and slicing to be made into crystalline silicon wafers for use. Among them, the slicing process is carried out by a slicing machine, which is used to slice the squared silicon rod to form silicon wafers. The wire cutting machine in the embodiment of the present utility model can especially slice a half crystal rod and has a high cutting efficiency.
