Referring to FIGS. 7 and 8, the feeding device 351 is used for receiving and transporting the biochip to a predetermined position. The feeding device 351 further includes a vibration plate 3511 and a guide 3512 having a feeding chute 35111 and a discharge port (not shown). The guide 3512 is located outside the vibration disk 3511 and communicates with a discharge port of the vibration disk 3511. A vibration rail 35112 is arranged in the vibration disc 3511, and the vibration rail 35112 is used for outputting the biochips entering the feed chute 35111 to the guide 3512 after being orderly arranged.

It is understood that the image recognizing unit may be disposed in the control unit 36, the image capturing unit 3521 transmits the captured image of the biochip to the control unit 36, and the control unit 36 recognizes the identifier on the biochip according to the image of the biochip to obtain the identifier information.
The recognition means 352 further includes a position recognizer 3522, the position recognizer 3522 is configured to recognize whether the biochip is moved to the predetermined position and transmit the generated corresponding recognition result to the control means 36. The control unit 36 controls the image-capturing part 3521 to capture an image of the biochip according to the recognition result that the biochip has moved to the predetermined position.

The signal emitter 35221 is used to emit a laser signal for emission through the detection hole 35122 to the signal receiver 35222. Since the biochip moves to the sensing hole 35122 to shield the sensing hole 35122, the signal receiving part 35222 does not receive the laser signal, and thus, the signal receiving part 35222 determines that the biochip moves to a predetermined position when the laser signal is not received. On the contrary, the signal receiving part 35222 judges that the biochip has not moved to the predetermined position when the laser signal is received.
In another embodiment, the recognition device 352 does not include the position recognizer 3522, and when the recognition device 352 does not include the position recognizer 3522, the image capturing unit 3521 continuously captures images at a predetermined position, and the image recognizer judges whether the predetermined position includes a biochip and recognizes a mark on the biochip based on the continuously captured images.
Referring to fig. 6 and 7 again, the plurality of receiving members 353 includes a plurality of first receiving members 3531, second receiving members 3532 and third receiving members 3533.

In this embodiment, the number of the first containers 3531 is four, and the four containers correspond to four reaction vessels 3551. The four first containers 3531 correspond to the four reaction vessels 3551, respectively. The second container 3532 includes a plurality of container regions 35321, and the container regions 35321 are used for containing biochips in which all synthesis reactions are completed. The third container 3533 is used for containing the biochip which cannot be identified.
The control device 36 determines whether the biochip is a biochip with all synthesis reactions completed or a biochip which cannot be identified or a biochip without synthesis sequence binding according to the identification information of the current biochip and the synthesis sequence of each biochip. The control unit 36 further determines a synthesis reaction to be currently performed and position information of one of the first receiving members 3531 to which the current biochip should be transferred when the current biochip is not a biochip in which all the synthesis reactions are completed, and transmits the transfer command including the position information to the robot 354 to control the robot 354 to transfer the biochip. The control unit 36 also determines position information of a receiving area 35321 in the second receiving member 3532 to which the current biochip should be transferred when the current biochip is a biochip in which all synthesis reactions are completed, and transmits the transfer instruction including the position information to the robot 354. The control device 36 further binds a synthesis sequence to the current biochip to make the current biochip a biochip with less than all synthesis reactions when the current biochip is a biochip without binding synthesis sequences, and correspondingly, sends a corresponding transfer instruction to the manipulator 354 when the biochip is a biochip with less than all synthesis reactions.
The robot 354 is used for transferring the biochip positioned at the predetermined position to the corresponding first container 3531, second container 3532 or third container 3533 according to a transfer instruction sent by the control device 36.

The robot arm 3541 is configured to drive the adsorption device 3542 to move to the predetermined position so that the adsorption device 3542 adsorbs the biochip, and to drive the adsorption device 3542 to move to a position above the first container 3531 to which the biochip should be transferred so that the adsorption device 3542 releases the biochip into the corresponding first container 3531. The robot arm 3541 is also reset after the adsorption apparatus 3542 releases the biochip to wait for the next transfer operation of the biochip.
In one embodiment, the suction device 3542 includes a negative pressure suction nozzle 35421 and a negative pressure air supply device 35422 connected to the negative pressure suction nozzle 35421. The control unit 36 controls the negative pressure air supply unit 35422 to be turned on when the suction unit 3542 moves to the predetermined position so that the negative pressure suction nozzle 35421 sucks up the biochip at the predetermined position, and controls the negative pressure air supply unit 35422 to be turned off when the suction unit 3542 moves to above the first container 3531 to which the sucked biochip should be transferred so that the negative pressure suction nozzle 35421 releases the biochip in the corresponding first container 3531.

The synthesis reaction performed in each reaction vessel 3551 is different, and for example, four reaction vessels 3551 are used for adenine (a), thymine (T), cytosine (C) and guanine (G) synthesis.
Specifically, each of the reaction vessels 3551 includes a synthesis reaction column 35511 and a sealing cover 35512 openably and closably connected to the synthesis reaction column 35511. The sealing cap 35512 is used to seal the synthesis reaction column 35511 to make the biochip complete the synthesis reaction. When the sealing cap 35512 is not covering the synthesis reaction column 35511, it is used to place a biochip into the synthesis reaction column 35511. The reaction device 355 further includes an opening and closing driving member 3552, and the opening and closing driving member 3552 is connected to the sealing cover 35512 for driving the sealing cover 35512 to ascend and descend so that the sealing cover 35512 is separated from or seals the synthesis reaction column 35511.
The plurality of reaction vessels 3551 may be switched among a material receiving station, a material reaction station, and a material discharge station.
