[0028] In order to better explain the present invention and facilitate understanding, the following Figure 1-2 , the utility model is described in detail through specific implementation methods. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 1 The orientation is used as a reference.

[0029] Embodiment 1:

[0030] Reference Figure 1 and Figure 2The embodiment of the utility model provides a transfer device for silicon crystal blanks, comprising a transport platform 1 and a turning platform 2, wherein a first supporting surface A of the silicon crystal blanks is formed on the transport platform 1, and a transport space that satisfies the movement of the silicon crystal blanks is formed on the transport platform 1; the turning platform 2 comprises a turning unit, and the turning unit comprises a plurality of groups of turning frames 21 arranged in parallel, and the turning unit can rotate along the parallel arrangement direction of the turning frames 21, and the side surfaces of all the turning frames 21 facing the rotation direction of the turning frames 21 form a second supporting surface B, and the first supporting surface A and the second supporting surface B are both comb-shaped and interlaced with each other; the number of the parallel arrangement of each group of turning frames 21 can be increased or decreased to match the length of the silicon crystal blanks;

[0031] The flipping unit can rotate and switch between the yielding position and the carrying position; when the flipping unit rotates to the yielding position, the second supporting surface B is located below the first supporting surface A and the flipping unit makes way for transportation space; when the flipping unit rotates to the carrying position, the second supporting surface B rotates to above the first supporting surface A and passes through the first supporting surface A to support the silicon crystal blank.

[0032] In this embodiment, the silicon crystal blank can be transported via the transport platform 1 . When the silicon crystal blank on the transport platform 1 needs to be moved to other required workstations, the position of the silicon crystal blank can be changed via the turning platform 2 .

[0033] The flipping unit has two position states, one of which is the yield position, which corresponds to the position of the silicon crystal billet when it is transported by the transport device, that is, it corresponds to the position of the flipping unit when the silicon crystal billet is on the first supporting surface A. At this time, the flipping unit is located below the second supporting surface B and makes room for transportation, so that the original carrying function of the transport device will not be affected; the second is the carrying position. During the position switching process of the flipping unit, the silicon crystal billet on the transport platform 1 will be lifted up by the second supporting surface B to make the silicon crystal billet detach from the transport platform 1. In conjunction with other devices, the transfer of the silicon crystal billet can be realized.

[0034] Since the present invention adopts a comb-tooth-shaped first supporting surface A and a second supporting surface B that intersect each other, when arranging the transport platform 1 and the turning platform 2, the distance between the two can be reduced, thereby improving the structural compactness of the silicon crystal blank transfer device. In addition, the arrangement flexibility of the comb-tooth-shaped first supporting surface A and the second supporting surface B is better, which can effectively ensure that the silicon crystal blank has sufficient contact area with it, thereby ensuring that the structure of the silicon crystal blank is not damaged during operation.

[0035] Furthermore, since the number of parallel arrangements of each group of turning racks 21 can be increased or decreased, when the length of the silicon crystal billet changes, the length of the silicon crystal billet can be matched by increasing or decreasing the number of turning racks 21, thereby further improving the flexibility of use of the transfer device.

[0036] In this embodiment, the turning table 2 also includes a circular ring, which is arranged in parallel along the axial direction of the rotating shaft 23 and is detachably connected to the rotating shaft 23; the turning frame 21 is fixedly connected to the circular ring so that a group of turning frames 21 arranged in parallel form an integrated structure.

[0037] The circular ring makes each group of the turning frames 21 independent of each other in structure, so that each group of the turning frames 21 can be disassembled and assembled as a whole, thereby improving the adjustment efficiency and difficulty of the turning unit.

[0038] Specifically, the spacing between adjacent circular rings can be limited by a shaft sleeve, the rotating shaft 23 can be set as a spline shaft, and the circular ring forms a spline hub that cooperates with the spline shaft.

[0039] Specifically, in the yielding position, the first supporting surface A is horizontal; in the bearing position, the first supporting surface A is vertical; the first supporting surface A and the second supporting surface B are perpendicular to each other.

[0040] The turning direction of the flip unit is clockwise or counterclockwise. By continuously rotating the flip unit in one direction, the position switching of the flip unit can be achieved.

[0041] Furthermore, the transport platform 1 includes a plurality of rollers 12 which are arranged in parallel and can actively rotate, and the top cross-section of the rollers 12 forms a first supporting surface A.

[0042] In this embodiment, the roller 12 may be an electric roller with driving force, and the silicon crystal blanks can be transported by the operation of the roller 12 .

[0043] Furthermore, the transport platform 1 also includes a frame 11, and the rotating rods are connected to the frame 11 in parallel along the length direction of the frame 11. The frame 11 enables the transport platform 1 to have a certain height, which can not only better bear the silicon crystal stone blanks, but also make operating space for the rotating turning unit, thereby facilitating the arrangement of the turning unit.

[0044] In this embodiment, the flip frame 21 includes a first frame body 211 and a second frame body 212. The second frame body 212 is connected to the side of the first frame body 211 close to the rotation axis of the flip unit. A second supporting surface B is formed on the first frame body 211, and a third supporting surface C perpendicular to the second supporting surface B is formed on the second frame body 212. When the flip frame 21 rotates to the load-bearing position, the second supporting surface B and the third supporting surface C jointly support the silicon crystal blank.

[0045] In this embodiment, the turning unit has not only the second supporting surface B but also the third supporting surface C to ensure that the stone slab will not separate from the second supporting surface B during the rotation of the turning unit, thereby improving the stability of the stone slab during operation.

[0046] The first frame 21 and the second frame 22 are connected to form an L shape.

[0047] In this embodiment, the flip table 2 also includes a rotating drive member 22 and a rotating shaft 23. The rotating shaft 23 is driven and connected to the torque output end of the rotating drive member 22. The flip unit can be detachably connected to the rotating shaft 23. Multiple flip units are symmetrically distributed along the axis center of the rotating shaft 23; the flip frame 21 is arranged in parallel along the axis direction of the rotating shaft 23.

[0048] In this embodiment, the rotating drive member 22 is used to drive the rotating shaft 23 to rotate, and the flip unit is driven to operate by the rotating shaft 23. The flip table 2 also includes a frame, and the rotating shaft 23 and the rotating drive member 22 are supported on the frame. The flip units distributed in the center can all support silicon crystal blanks. In this way, when the rotating shaft 23 rotates one circle, the corresponding flip unit can switch from the yielding position to the bearing position, that is, when the rotating shaft 23 rotates one circle, it can complete the operation of multiple silicon crystal blanks, which reduces the transportation time interval of silicon crystal blanks, improves the continuity of the use of the flip table 2, and further improves the transportation efficiency of silicon crystal blanks.

[0049] Specifically, when the flip unit is in the yielding position, the second supporting surface B is in a horizontal state parallel to the first supporting surface A, and the third supporting surface C is in a vertical state; when the flip unit is in the bearing position, the second supporting surface B is in a vertical state, and the third supporting surface C is in a horizontal state.

[0050] The rotating driving member 22 can be configured as a stepping motor to precisely adjust the rotation angle of the flip unit. Meanwhile, the number of flip units can be four.

[0055] The robot 4 includes a crossbeam and a plurality of bracket units 41 connected in parallel to the crossbeam. The bracket unit 41 includes a transverse bracket 411 and a vertical bracket 412 which are perpendicular to and connected to each other. A fourth supporting surface D and a fifth supporting surface E which are close to and perpendicular to each other are formed on the transverse bracket 411 and the vertical bracket 412. The adjacent fourth supporting surfaces D of adjacent bracket units 41 overlap, and the adjacent fifth supporting surfaces E of adjacent bracket units 41 also overlap. The fourth supporting surface D can support the silicon crystal blank supported by the flipping unit.

[0056] In this embodiment, the manipulator 4 is a bracket structure, which includes bracket units 41 arranged in parallel, the horizontal bracket 411 can support the bottom surface of the silicon crystal stone blank after being erected, that is, the fourth supporting surface D can support the silicon crystal stone blank, and the vertical bracket 412 can lean on the side surface of the silicon crystal stone blank after being erected, that is, the silicon crystal stone blank can lean on the fifth supporting surface E. In this way, the manipulator 4 can not only support the silicon crystal stone blank, but also ensure the stability of the silicon crystal stone blank.

[0057] The robot arm 3 is a conventional multi-axis electrically controlled robot arm 3, which will not be described in detail here.

[0058] At the same time, the length of the bracket unit 41 must also match the actual length of the silicon crystal stone blank, which can be achieved by increasing or decreasing the number of bracket units 41.

[0059] Specifically, soft pads, such as rubber pads, are provided on the first supporting surface A, the second supporting surface B, the third supporting surface C, the fourth supporting surface D and the fifth supporting surface E to protect the silicon crystal blank and prevent the silicon crystal blank from being damaged due to contact stress.

[0060] The robot 4 also includes a telescopic drive member 42 and a pressure block 43. The telescopic drive member 42 is directly or indirectly connected to a side of the vertical bracket 412 away from the horizontal bracket 411. The pressure block 43 is driven and connected to the telescopic end of the telescopic drive member 42 so that the pressure block 43 can press the silicon crystal blank between the pressure block 43 and the horizontal bracket 411.

[0061] In this embodiment, the telescopic driving member 42 is used to drive the pressing block 43 to slide vertically, so as to vertically press the top surface of the silicon crystal blank, thereby improving the stability of the silicon crystal blank in the robot arm 4.

[0062] The telescopic drive member 42 may be connected to the crossbeam.
