The application discloses a chess piece receiving and sending mechanism, which comprises a chess box, a waiting area, a first driving device and a second driving device. The chess box can accommodate chess pieces and is provided with permanent magnets. The polarities of the permanent magnets of the chess pieces are consistent. In the chess box, the chess pieces are stacked along the axial direction of the chess box. Any two adjacent chess pieces are attracted to each other under the action of magnetic force, and a chess piece unit is formed. The waiting area is arranged at one end of the chess box. The first driving device is in transmission connection with the chess piece unit, so as to drive the chess piece unit to move along the axial direction of the chess box. The second driving device can drive the chess pieces to switch between the chess box and the waiting area. The chess pieces are orderly arranged in the chess box. Through cooperation of the first driving device and the second driving device, the chess pieces can be switched between the chess box and the waiting area. The whole process is automatically operated, so that man-machine chess playing and remote chess playing can be realized, the chess piece output rate can be improved, and the efficiency can be improved. The application further discloses a chess piece and a chessboard.

The application discloses a whole piece device and an automatic wafer loading and unloading machine, and relates to the technical field of wafer production. The whole piece device comprises a whole piece assembly, and the whole piece assembly comprises a first whole piece unit, a second mounting seat, a first positioning wheel and a first pressure sensor. The first mounting seat is slidably arranged on a rack along the width direction of a belt line. The second mounting seat is movably arranged on the first mounting seat along the width direction of the belt line. The first positioning wheel is rotatably arranged on the second mounting seat. The first pressure sensor is arranged on the rack. The test end of the first pressure sensor is connected with the second mounting seat to detect the pressure generated when the first positioning wheel contacts the wafer. The controller is electrically connected with the first pressure sensor. The controller is used for controlling the working state of the automatic wafer loading and unloading machine according to the pressure detected by the first pressure sensor. The controller can avoid the wafer from being broken or having a broken edge due to excessive pressure. The application effectively improves the production yield and the overall production efficiency of the wafer.
