[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1-Figure 5 As shown, the utility model discloses a rotating inserting and removing sheet structure, which is characterized by comprising:

[0028] A support assembly 1, the support assembly 1 comprises a support frame 11 and a base 12, the base 12 is inserted into the support frame 11, a mechanical arm 14 is arranged on the base 12; beams 13 are arranged on both sides of the support frame 11;

[0029] A rotating assembly 2, the rotating assembly 2 comprising a driving source 21 and a rotating plate 22, the driving source 21 being arranged between the two beams 13, and a driving gear 23 being arranged at the output end of the driving source 21; the rotating plate 22 being arranged on the supporting frame 11, and a driven gear 24 being arranged between the rotating plate 22 and the supporting frame 11, and the driven gear 24 being meshed with the driving gear 23; a first material storage rack 25 and a second material storage rack 26 being arranged at the top of the rotating plate 22, the first material storage rack 25 and the second material storage rack 26 being symmetrically arranged at both sides of the base 12, and the length direction of the first material storage rack 25 and the length direction of the second material storage rack 26 are both tangent to the outer edge of the driven gear 24;

[0030] The loading and unloading assembly 3 includes a first conveying frame 31 and a second conveying frame 32 . The first conveying frame 31 and the second conveying frame 32 are arranged on one side of the support frame 11 , and the length direction of the first conveying frame 31 is parallel to the length direction of the second conveying frame 32 .

[0031] It can be imagined that the driving source 21 rotates to drive the driving gear 23 to rotate, and then drives the driven gear 24 to rotate, and the rotating plate 22 is arranged on the support frame 11 and connected to the driven gear 24, driving the entire rotating plate 22 to rotate. Two storage racks are arranged on the top of the rotating plate 22, and the first storage rack 25 and the second storage rack 26 are symmetrically arranged on both sides of the base 12. Graphite boats 4 can be placed on the first storage rack 25 and the second storage rack 26, and silicon wafers are placed in the graphite boat 4. The base 12 is penetrated in the middle of the support frame 11, and the mechanical arm 14 is arranged on the top of the base 12. The mechanical arm 14 can grab the silicon wafers on the storage racks on both sides. The two graphite boats 4 are arranged on both sides of the mechanical arm 14, which can greatly reduce the movement trajectory of the mechanical arm 14 and shorten the time for transporting silicon wafers.

[0032] Secondly, the loading and unloading assembly 3 is arranged on one side of the support frame 11, wherein the first conveyor frame 31 corresponds to the first storage rack 25, and the second conveyor frame 32 corresponds to the second storage rack 26. Specifically, when the driving source 21 rotates to align the first storage rack 25 and the first conveyor frame 31 in the same straight line, the first conveyor frame 31 conveys the graphite boat 4 with the silicon wafers to the first storage rack 25, and at the same time, the robotic arm 14 moves to grab the silicon wafers in the graphite boat 4 on the second storage rack 26. When the silicon wafers in the graphite boat 4 on the second storage rack 26 are grabbed, the driving source 21 reverses to align the second storage rack 26 and the second conveyor frame 32 in the same straight line, and the graphite boat 4 on the second storage rack 26 is unloaded and replaced. At the same time, the robotic arm 14 grabs the silicon wafers in the graphite boat 4 on the first storage rack 25 that has just been loaded, and this reciprocating cycle is repeated. It can be seen that when the robot arm 14 grabs the silicon wafer, it does not need to wait for the replacement of the graphite boat 4, which greatly reduces the waiting time for loading when the robot arm 14 grabs the silicon wafer, maintains uninterrupted operation, and improves production efficiency.

[0033] Furthermore, the rotating plate 22 is provided with an escape opening 221, and the escape opening 221 is sleeved on the outer side of the base 12. Specifically, the escape opening 221 is opened in the middle of the surface of the rotating plate 22, and the base 12 on which the mechanical arm 14 is installed is placed in the middle through the escape opening 221, thereby reducing the movement track of the mechanical arm 14.

[0034] Furthermore, the rotating plate 22 is detachably connected to the end surface of the driven gear 24. The rotating plate 22 is fitted to the end surface of the driven gear 24 and is fastened by a plurality of bolts arranged circumferentially.

[0035] Furthermore, the angle between the axis of the first material storage rack 25 in the length direction and the axis of the second material storage rack 26 in the length direction is 60°.

[0036] As a preferred solution of the present invention, the angle formed between the first storage rack 25 and the second storage rack 26 is 60°. The 60° rotation can greatly reduce the boat changing time and improve the production capacity of the photovoltaic equipment automation equipment.

[0037] Furthermore, the first material storage rack 25 and the second material storage rack 26 are both provided with boat transfer lines along the longitudinal axis direction.

[0038] Specifically, the first material storage rack 25 and the second material storage rack 26 are both provided with a boat transfer conveyor line for transporting the graphite boat 4 on the first conveyor rack 31 and the second conveyor rack 32 to the first material storage rack 25 and the second material storage rack 26. As a preferred solution in the utility model, the first conveyor rack 31, the second conveyor rack 32 and the boat transfer conveyor line have the same structure, and are all driven by a private service motor to drive the conveyor belt to move, and their function is to realize the transportation of the graphite boat 4, and the reciprocating motion of the graphite boat 4 is realized by the forward and reverse rotation of the private service motor. As the prior art, the first conveyor rack 31, the second conveyor rack 32 and the boat transfer conveyor line are not described in detail here.

[0039] Furthermore, a baffle 251 is provided on one side of the first storage rack 25 and the second storage rack 26 along the length direction, and a support beam 252 is provided on the other side of the first storage rack 25 and the second storage rack 26 along the length direction, and a first alignment cylinder 253 is provided on the support beam 252, and an alignment frame 254 is provided at the telescopic end of the first alignment cylinder 253.

[0040] Specifically, refer to Figure 5 As shown, in actual operation, after the graphite boat 4 enters the first storage rack 25, the first alignment cylinder 253 extends and drives the first alignment cylinder 253 to position and limit the length direction of the graphite boat 4, so that the graphite boat 4 is clamped between the alignment rack 254 and the baffle 251, and the width direction of the graphite boat 4 is fixed.

[0041] As a preferred solution of the present invention, in order to avoid damage to the surface of the graphite boat 4 during the alignment process, a plurality of buffer blocks 255 are provided on a side of the alignment frame 254 away from the first alignment cylinder 253 .

[0042] Furthermore, a limiting frame 256 is provided at one end of the first storage rack 25 and the second storage rack 26 along the width direction, and a lifting cylinder 257 is provided at the other end of the first storage rack 25 and the second storage rack 26 along the width direction, and a lifting plate is provided at the telescopic end of the lifting cylinder 257, and a second alignment cylinder 259 is provided on the lifting plate, and a top plate 261 is provided at the telescopic end of the second alignment cylinder 259.

[0043] Specifically, the action of the lifting cylinder 257 drives the lifting plate to rise and fall. When the graphite boat 4 needs to be replaced, the lifting rod 258 is lifted to transport the graphite boat 4 to the first storage rack 25 or the second storage rack 26. Then the lifting rod 258 is lowered, and the second alignment cylinder 259 is extended to drive the top plate 261 to abut against the graphite boat 4, so that the graphite boat 4 is close to the limit rack 256, and the length direction of the graphite boat 4 is fixed. As a preferred embodiment of the present invention, a boat support can also be provided at the bottom of the graphite boat 4 to support and protect the graphite boat 4. Since the first storage rack 25 and the second storage rack 26 have the same structure and the same function, no further description will be given here.

[0044] Furthermore, a plurality of guide wheels 262 are provided on one side of the limiting frame 256 close to the lifting cylinder 257 .

[0045] Specifically, during the operation, the first alignment cylinder 253 will drive the graphite boat 4 to move in the width direction. The plurality of guide wheels 262 can assist the movement of the graphite boat 4 to avoid direct contact and friction between the graphite boat 4 and the limiting frame 256 .
