Description

Technical Field

[0001] The utility model relates to the technical field of crystalline silicon processing equipment, in particular to a material taking device and a cutter. Background Art

[0002] At present, solar photovoltaic silicon wafers are widely used in the photovoltaic field. The manufacturing process of silicon wafers used to make solar panels is divided into: crystal pulling, truncation, squaring, grinding, slicing, etc. Truncation refers to cutting single crystal or polycrystalline silicon rods into rods of the required length by a truncation machine, and also truncation of the head and tail of the material to obtain the head and tail. In other words, after the raw crystal rod made by pulling or casting is placed in the truncation station of the truncation machine, the truncation device of the truncation machine is used to cut at multiple positions of the raw crystal rod, and the head, tail, test samples and multiple shorter lengths of pre-processed raw crystal rods can be obtained at the same time. The pre-processed raw crystal rod can be subsequently squared, sliced, and other operations.

[0003] In the prior art, the middle of the raw crystal ingot is usually supported when it is in the cutting station. After the cutting device cuts, the head material will automatically fall onto the head material cart, and it is easy to fall outside the head material cart, which cannot ensure the transportation of the head material, that is, the head material cannot be quickly and effectively transported, and the fall will also cause damage to the head material. Moreover, as the cutting and cutting proceeds, the connection between the head material and the main body of the crystal ingot becomes less and less. The head material moves relative to the main body of the crystal ingot due to its own gravity or other reasons, causing damage to the head material or the rest of the material ingot, affecting the quality of the primary processed raw crystal ingot, that is, the cutting of the material ingot cannot be ensured.

[0043] The material taking device can be movably mounted on the frame to move to one end of the cutting station, and the material taking device supports the head end of the material to be processed at the cutting station.

[0044] In the material taking device and the cutting machine of the utility model, since there are an end tightening block and two side clamping blocks, before the cutting machine cuts the material rod, the end tightening block is pressed against the head end of the head material, and the side clamping blocks are pressed against the two sides of the head material, so that the end tightening block and the side clamping blocks support the head material, and then the cutting machine cuts, and the head material can be effectively supported during the cutting process, so the material taking device can protect the head material and the rest of the material rod, and prevent the head material and the rest of the material rod from being damaged due to incomplete cutting.

Moreover, since the end clamping block and the two side clamping blocks are also movably arranged, the clamping space can be enlarged or reduced, and it is obvious that it can be used for head materials of different sizes, at least it can adapt to material rods of different thicknesses.

[0047] Furthermore, in the material picking device and cutting machine of the utility model, due to the position of the rotating rod, the structure of the entire device can be compact and the space can be reasonably utilized; and the layout positions of the translation device, the rotating device, and the mounting frame are all conducive to the setting of the material picking device and the application of the material picking device in the cutting machine.

[0050] Furthermore, in the material taking device and the cutting machine of the utility model, the end stopper can be moved to the outside of the clamping space by rotating the end stopper, and then the end stopper is moved to a suitable position, so as to minimize the influence on the operation of other parts in the cutting machine. When the end stopper is needed, the end stopper can be moved to the corresponding end of the clamping space.

[0069] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0070] like Figure 1 As shown, and refer to Figures 2 to 8 The embodiment of the utility model provides a material taking device, which includes a support frame 10, an end clamping block 21, an end stop assembly and two side clamping blocks 31. The end stop assembly includes an end stopper 41.

[0071] The two side clamping blocks 31 are arranged on the support frame 10 in a relative manner so that a clamping space is formed between the two side clamping blocks 31. That is to say, the two side clamping blocks 31 are used to clamp the two sides of the head material, especially the two sides of the head material. The space defined between the two side clamping blocks 31 for carrying the head material can be called a clamping space. The end clamping block 21 is arranged on the support frame 10 and is located at one end of the clamping space. The end stopper 41 is configured to be located at the other end of the clamping space. That is to say, the end stopper 41 is used to be arranged opposite to the end clamping block 21 and to clamp the two ends of the head material.

[0072] In this embodiment, the end stopper 41 is movably arranged relative to the support frame 10 to be away from the end clamping block 21 or close to the end clamping block 21. The end stopper 41 is rotatably arranged relative to the support frame 10 to rotate to the other end of the clamping space. The rotation axis of the end stopper 41 extends along the moving direction of the end stopper 41.

[0073] In this embodiment, before the cutter cuts the material rod, the end clamping block 21 is pressed against the head end of the head material, and the side clamping blocks 31 are pressed against both sides of the head material, so that the end clamping block 21 and the side clamping blocks 31 support the head material, and then the cutter cuts it. This arrangement can effectively support the head material during the cutting process, so the material removal device can protect the head material and the rest of the material rod, and prevent the head material and the rest of the material rod from being damaged due to incomplete cutting. That is, the material removal device can safely cut the head material.

[0074] Furthermore, after the head material is cut off, the end stopper 41 can move to a preset position and then rotate to be inserted into the cut to clamp the head material. That is, the end stopper 41 moves and cooperates with the end clamping block 21 to support and clamp the two ends of the head material. The two side clamping blocks 31 can be used to support and clamp both sides of the head material to prevent the head material from falling and protect the head material.

[0075] The end stopper 41 can be rotated to move to the outside of the clamping space, and then moved to the preset position to minimize the impact on the work of other parts in the cutter. For example, in the process of cutting the head of the material rod, the end stopper 41 is in a position that does not affect the cutting. Then the entire material removal device can be moved to the preset position as a whole for the transfer of the head material, so that the head material can be taken out at the preset position. The material removal device can prevent the head material from falling from the material removal device during the transfer of the head material, that is, the material removal device can safely realize the transfer of the head material, which is more conducive to the head material to the next process.

[0076] In the material taking device of the embodiment of the utility model, in the initial position, the end stopper 41 is in a suitable position and is not at the corresponding end of the clamping space, so as to minimize the impact on the work of other parts or devices when there is no clamping of the head material. When it is necessary to clamp the head material, the end stopper 41 can be moved in the direction away from the end tightening block 21, and the end stopper 41 can be rotated to a position opposite to the end tightening block 21, and then the end stopper 41 can be moved in the direction close to the end tightening block 21 to support, clamp and clamp the head material. Of course, in other embodiments of the utility model, when in the initial position, the end stopper 41 is in a position opposite to the end tightening block 21. When it is necessary to cut the head material, the end stopper 41 can be moved and rotated to a position where it can give way to prevent affecting the cut head material.

[0077] The material taking device of the embodiment of the utility model can support, collect and transport the head material, and there is no need to use a robot to take out the head material and then place it, which can ensure a smooth cutting process and save processing time.

[0078] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the end clamping block 21 is movably arranged relative to the support frame 10 to be away from the end stopper 41 or close to the end stopper 41. Each side clamping block 31 is movably arranged relative to the support frame 10 to be away from the other side clamping block 31 or close to the other side clamping block 31.

[0079] The material taking device of the utility model can adapt to head materials of different sizes by moving the end clamping block 21 and the two side clamping blocks 31, and can solve the problem that the end shapes of the single crystal silicon rods are diverse and inconsistent and cannot be effectively recovered after the crystal pulling is completed. That is, the material taking device of the embodiment of the utility model realizes the automatic collection of head silicon materials of different sizes generated during the truncation process. Moreover, since the end clamping block 21 and the two side clamping blocks 31 can also be movably arranged, it is convenient to clamp and support the head material. For example, the material taking device can be moved into place first, and then the end clamping block 21 and the two side clamping blocks 31 can be moved to clamp, which can prevent the material taking device from moving into place and clamping at the same time to cause damage to the material rod.

[0080] In some embodiments of the present invention. Figure 1 and Figure 4As shown, the upper surface of the end clamping block 21 is a groove surface 211, and the end clamping block 21 has a first inclined surface 212, and the upper end of the first inclined surface 212 is connected to one end of the groove surface 211 adjacent to the end stopper 41. The lower end of the first inclined surface 212 is closer to the end stopper 41 than the upper end of the first inclined surface 212, that is, the first inclined surface 212 faces obliquely upward. Due to the special structure of the end clamping block 21, it is particularly conducive to the support of the head material and basically does not damage the head material. Further, the groove can be a V-shaped groove, that is, the cross-sectional profile of the groove is V-shaped.

[0081] In some embodiments of the utility model, the surface of each side clamping block 31 facing the other side clamping block 31 includes a second inclined surface 311, the second inclined surface 311 is connected to the upper surface of the side clamping block 31, and the second inclined surface 311 faces obliquely upward. The provision of the side clamping block 31 is also conducive to protecting the head material. In the embodiment of the utility model, since the head material is relatively short, the side clamping block 31 can clamp the two side surfaces of the tapered portion of the head material. The shape of the second inclined surface 311 is more conducive to clamping.

[0082] In some embodiments of the present invention, the end stopper 41 is a stopper bar or a stopper block, and the stopper bar is rotatably arranged around one end thereof relative to the support frame 10. In the initial position, the stopper bar is vertically upward.

[0083] In some embodiments of the present invention, Figure 5 , Figure 6 and Figure 7 As shown, the end stop assembly further includes a first translation device 42, a first rotation device 43 and a rotation rod 44. The rotation rod 44 extends along the moving direction of the end stop 41. The end stop is arranged at one end of the rotation rod 44, and the other end of the rotation rod 44 is connected to the first rotation device 43, so as to rotate under the drive of the first rotation device 43 and drive the end stop to rotate, thereby making the end stop 41 rotatably arranged relative to the support frame 10. The first translation device 42 is installed on the support frame 10. The first rotation device 43 is connected to the first translation device 42, so as to move under the drive of the first translation device 42, and drive the rotation rod 44 and the end stop to move, thereby making the end stop 41 movably arranged relative to the support frame 10.

[0084] When the head material is taken out after being cut off, the first translation device 42 extends, the first rotation device 43 drives the rotating rod 44 to rotate 90 degrees, and the baffle is in a horizontal state, which plays a role in blocking the head material from falling.

[0085] In some embodiments of the present invention, the rotating rod 44 is located outside a side clamping block 31, and a corresponding position on the outer surface of the side clamping block 31 is provided with a clearance groove 312 for making way for the rotating rod 44. Due to the location of the rotating rod 44, the entire device can be compact and space can be reasonably utilized.

[0086] In some embodiments of the present invention, the material taking device further comprises two second translation devices 32 and a third translation device 22. Each second translation device 32 is configured to drive a side clamping block 31 to move. Each second translation device 32 is mounted on the support frame 10. The third translation device 22 is mounted on the support frame 10 and configured to drive the end clamping block 21 to move.

[0087] In some embodiments of the present invention, the first translation device 42, the second translation device 32 and the third translation device 22 are all telescopic cylinders, and the first rotation device 43 is a rotary cylinder. In some alternative embodiments of the present invention, the first translation device 42, the second translation device 32 and the third translation device 22 can be a gear rack mechanism, a nut screw mechanism, a linear motor, etc.

[0088] In some embodiments of the present invention, Figures 1 to 3 ,as well as Figure 8 As shown, the material picking device also includes a sample adsorption device, which includes a suction cup 51, a connecting rod 52 and a second rotating device 53. The second rotating device 53 is installed on the support frame 10, and one end of the connecting rod 52 is connected to the output shaft of the second rotating device 53, so as to rotate under the drive of the second rotating device 53. The output shaft of the second rotating device 53 extends along the moving direction of the end stopper 41. The suction cup 51 is arranged at the other end of the connecting rod 52, and the center line of the suction cup 51 is arranged at an interval with the straight line where the output shaft of the second rotating device 53 is located. The suction cup 51 is located on the upper side between the two side clamping blocks 31, or it can be said that the suction cup 51 is located at a position directly opposite to the material rod in the clamping space, for example, the position of the suction cup 51 can be higher than the position of the side clamping block 31, which is convenient for the placement of the material picking device when the material picking device is not working, so that the structure of the material picking device is compact. And the position of the suction cup 51 is convenient for the suction cup 51 to adsorb the sample.

[0089] In this embodiment, the suction cup 51 set eccentrically (i.e., deviating from the rotation center) can absorb the sample cut by the cutter when the material taking device does not take the head material, and then transport the sample to the position where the sample needs to reach. Specifically, after the cutter completes the cutting, the second rotating device 53 operates to realize the rotation in the first direction, such as 180° counterclockwise, and the suction cup 51 rotates from outside the working area to inside the working area to absorb the sample. After the sample is absorbed, it rotates 180° clockwise in the second direction to rotate the sample outside the working area and place it in a special sample collection area. It should be noted that since the sample is relatively light, it will not fall immediately after being cut, and the sample can be absorbed before it falls.

[0090] The specific working process of the material taking device of the embodiment of the utility model can be as follows: the end clamping block 21 and the two side clamping blocks 31 first clamp the head material, and then the cutter cuts the head material, the tail material and the rod material of the target length, and then the end stopper 41 can move into the slit to clamp the head material and prevent it from falling. The overall movement of the material taking device allows the head material to move to the corresponding target position, and then the head material can be taken off. After the head material is taken off, the material taking device moves as a whole and can move to a position convenient for the suction cup 51 to take the material. By rotating the connecting rod 52, the suction cup 51 moves to the material taking position to absorb the sample, and then the sample is transported to the corresponding target position by rotating the connecting rod 52 or by rotating the connecting rod 52 and the overall movement of the material taking device, and the sample is released.
