The gripping mechanism 122 can then be moved on the frame 121 in the first direction X and in the vertical direction Y to effect transfer of the rejected silicon rod 20. Because the buffer roller way 11 and the transfer trolley 30 are arranged along the first direction X, when the grabbing mechanism 122 drives the unqualified silicon rods 20 to transfer along the first direction X, the moving distance of the grabbing mechanism 122 can be made to be the shortest, and therefore, the unqualified silicon rods 20 can be transferred with high efficiency.

In the event that the transfer trolley 30 is not parked in the trolley parking mechanism 13, then there is no need to activate the truss manipulator 12.

The second sensor may include an infrared sensor, a hall sensor, etc. and the embodiment of the present utility model is not limited to the specific form of the second sensor

In practice, the reject silicon rods 20 output by the conveyor system are typically placed on a tray 40.

As shown in fig. 2, the discharging device may further include a tray roller way 15, where the tray roller way 15 is disposed adjacent to the buffer roller way 11, and the tray roller way 15 may be used to receive a tray 40 output by the buffer roller way 11. So as to avoid the tray 40 occupying the buffer roller way 11, and facilitate the buffer roller way 11 to continuously place the next tray 40 and the unqualified silicon rods 20 on the tray 40.

In this way, the pallet 40 can be transferred from the buffer roller table 11 to the pallet roller table 15 by the cooperation of the first lifting transplanting mechanism 111 and the second lifting transplanting mechanism 151.

The following provides an example of a working process of the blanking device according to the embodiment of the present utility model:

first, the transfer trolley 30 may be pushed to the trolley parking mechanism 13, and the conveying roller way 10 may be abutted with the conveying line of the silicon rod conveying system, so that the conveying roller way 10 receives the unqualified silicon rods 20 output by the silicon rod conveying system. After the tray 40 containing the defective silicon rods 20 is transferred onto the transfer table 10, the transfer table 10 may transfer the tray 40 containing the defective silicon rods 20 onto the buffer table 11, and after the tray 40 containing the defective silicon rods 20 reaches the buffer table 11, the transfer table 10 may stop running.

Then, the first driving mechanism 125 may be activated to drive the gripping mechanism 122 to move in the first direction X to above the buffer roller table 11, and then stop. Then, the second driving mechanism 126 is started to drive the second cross beam 124 and the grabbing mechanism 122 to descend to the position of the failed silicon rod 20 in the vertical direction Y, and then the operation is stopped. The third drive mechanism 1222 then drives the bi-directional roller screw 1224 to rotate, thereby driving the two-sided clamping jaw 1225 to close and clamp the failed silicon rod 20 by the rotation of the bi-directional roller screw 1224. After the clamping jaw 1225 clamps the defective silicon rod 20, the second drive mechanism 126 is activated to raise the second beam 124 and the grasping mechanism 122. The first drive mechanism 125 may be activated after the gripper mechanism 122 is lifted into place to drive the gripper mechanism 122 in the first direction X to move to the first station 301 of the transfer trolley 30 for placement of the reject silicon rod 20, after which the first drive mechanism 125 is deactivated. Next, the second driving mechanism 126 is activated to drive the gripping mechanism 122 to descend in the vertical direction Y to the station 301 on the transfer trolley 30 for placing the defective silicon rod 20, and stopped after that. Then, the third driving mechanism 1222 drives the bi-directional roller screw 1224 to rotate, so as to drive the two clamping jaws 1225 to open by the rotation of the bi-directional roller screw 1224, to release the clamping of the clamping jaw 1225 on the defective silicon rod 20, and place the defective silicon rod 20 on the station 301 of the transfer trolley 30. Then, the second driving mechanism 126 is started to drive the grabbing mechanism 122 to ascend and reset.

Finally, the first lifting and transplanting mechanism 111 and the second lifting and transplanting mechanism 151 are driven to lift simultaneously, and the tray 40 on the buffer roller way 11 is transferred from the first lifting and transplanting mechanism 111 to the second lifting and transplanting mechanism 151. After the tray 40 reaches the second lifting and transplanting mechanism 151, the first lifting and transplanting mechanism 111 and the second lifting and transplanting mechanism 151 may be lowered simultaneously. After the second lifting transplanting mechanism 151 descends, the tray 40 can be placed on the tray roller way 15, and after the tray roller way 15 descends in place, the tray 40 can be conveyed to the end part of the tray roller way 15 by starting. Then, the operation of transferring the defective silicon rod 20 from the conveying roller table 10 to the buffer roller table 11 is repeated until the defective silicon rod 20 is present at all the stations 301 of the transfer trolley 30, and then the operation is stopped.
