[0054] It should be noted that, in order to fully describe the entire high-throughput synthesis workstation, the frame 11, the equipment drive mechanism 2, and the automatic feeding drive device 6 are arranged side by side in the description of this specific embodiment. However, in reality, the frame and the equipment drive mechanism are a shared structure of the automatic feeding drive device. In order to realize the function of the automatic feeding drive device, the automatic feeding drive device in this utility model includes a frame and an equipment drive mechanism. Wherein:

[0055] The frame 11 primarily serves a supporting function. The equipment drive mechanism 2 is mounted on the frame. The equipment drive mechanism 2 primarily serves a driving function. In this specific embodiment, the equipment drive mechanism includes a front-to-back drive mechanism 21, a left-to-right drive mechanism 22, and a vertical drive mechanism 23. Wherein:

[0058] Left and right drive seats 221 are connected to the front and rear drive mechanism and move back and forth under the drive of the front and rear drive mechanism. Left and right guide rails 222 are fixed on the left and right drive seats and are arranged in the left and right direction.

[0065] The pipette 14 is supported on the support frame. To avoid mixing and contaminating the reaction solution during pipetting, multiple pipettes are usually provided so that different types of liquids can be drawn from the liquid container and added to the synthesis cup using different pipettes.

[0066] A multi-station oscillating heater 4 is mounted on the frame. The multi-station oscillating heater primarily supports the liquid container and simultaneously oscillates the liquid container to prevent sedimentation. Furthermore, it can heat the liquid as needed to bring it to the required temperature when added to the synthesis cup.

[0067] The liquid containers are supported on the multi-station oscillating heater. Multiple liquid containers are typically included, each used to hold a different type of solution.

[0068] A weighing module 16 is mounted on the frame. The weighing module is primarily used for weighing to accurately measure the weight of the powder and liquid added to the synthesis cup. In this specific embodiment, the weighing module 16 is connected to the rotary drive mechanism and controls the rotary drive mechanism based on the weighing result, thereby automatically controlling the dispensing of powder from the container according to the weighing result, resulting in more precise feeding.

[0069] The heating and stirring device 5 is mounted on the frame. This device is primarily used for heating and stirring during synthesis in the synthesis cups to meet the reaction conditions.

Then, the device drive mechanism drives the automatic dispensing drive device to clamp the powder container and, based on the weighing result from the weighing module, automatically and quantitatively dispenses the powder from the powder container into the synthesis cup. When liquid needs to be added, the device drive mechanism drives the pipetting device to grasp the pipette, move the pipette to the liquid container to draw the solution, and automatically and quantitatively inject the drawn solution into the synthesis cup. Furthermore, the multi-station oscillating heater can be used to oscillate the liquid container when needed to prevent sedimentation, or the multi-station oscillating heater can be used to heat the liquid container to reach a suitable temperature. Finally, the automatic feeding device can be driven by the equipment drive mechanism to clamp the synthesis cup onto the heating and stirring device. The heating and stirring device then heats and stirs the synthesis cup to meet the conditions for the synthesis reaction. This allows for the fully automated completion of all steps in the synthesis reaction, including adding powder, adding solution, heating, and stirring, resulting in a high degree of automation and efficiency.

[0074] In this specific embodiment, the powder container 3 includes a container shell 31, a container lid 32, a rotating device 33, a partition 34, and a discharge plate 35. Wherein:

[0075] The container shell 31 includes a hollow powder receiving cavity 311 disposed within the container shell and a discharge port 312 disposed on the lower surface of the container shell and communicating with the powder receiving cavity.

[0087] In this specific embodiment, the side of the container shell 31 is provided with an outwardly protruding placement and positioning part 313. The positioning part 313 is mainly used for positioning the powder container when it is placed on the support frame, so that the powder container can be placed on the support frame in a set direction, so as to facilitate the automatic feeding drive device to pick up and put the powder container on the support frame.

[0088] In this specific embodiment, the container cover 32 is also provided with a feed hole 325, and the powder container also includes a feed plug 326 that can be detachably inserted into the feed hole.

[0098] The automatic material unloading drive device 6 includes a material unloading fixing seat 61, a rotary drive mechanism 62, a connecting shaft 63, a clamping drive mechanism 64, and a clamping arm 65. Wherein:

[0099] The material unloading fixing seat 61 is connected to the equipment drive mechanism and moves under the drive of the equipment drive mechanism. The material unloading fixing seat mainly serves a supporting function. The equipment drive mechanism drives the material unloading fixing seat to move back and forth, left and right, and up and down, thereby driving the rotary drive mechanism, connecting shaft, clamping drive mechanism, and clamping arm to move back and forth, left and right, and up and down. In this specific embodiment, the material unloading fixing seat is disposed on the up and down drive mechanism and moves up and down under the drive of the up and down drive mechanism.

[0100] A rotary drive mechanism 62 is mounted on the material unloading fixing seat. The rotary drive mechanism is mainly used to drive the connecting shaft to rotate. In this specific embodiment, the rotary drive mechanism is implemented using a motor drive mechanism.

[0101] The connecting shaft 63 is connected to the rotary drive mechanism and rotates under the drive of the rotary drive mechanism. The lower end of the connecting shaft is provided with a drive connection part 631 that connects to the powder container; the connecting shaft is located below the rotary drive mechanism. The drive connection part can be inserted into the rotary connection part and drives the rotating device to rotate. The shape of the drive connection part matches that of the rotary connection part 631. In this specific embodiment, both the drive connection part and the rotary connection part are square, thus not only allowing for insertion between the two but also enabling the rotating device to rotate together when the connecting shaft rotates. In this specific embodiment, the drive connection part is square and integrally formed with the connecting shaft.

[0102] A clamping drive mechanism 64 is mounted on the material unloading station. The clamping drive mechanism is used to drive the clamping arm to move, thereby realizing the picking and placing of powder containers and synthesis cups.

[0103] The clamping arm 65 is connected to and located below the clamping drive mechanism. The clamping arm 65 includes a left clamping arm 651 and a right clamping arm 652 directly opposite the left clamping arm. The left and right clamping arms move relative to each other or relative to each other under the drive of the clamping drive mechanism. The clamping arms move forward, backward, left, right, and up and down through the device drive mechanism. Combined with the relative movement of the left and right clamping arms, the powder containers and synthesis cups at various locations can be picked up and placed.

[0104] This invention comprises a device drive mechanism, a material feeding fixing seat, a rotary drive mechanism, a connecting shaft, a clamping drive mechanism, and a clamping arm. The clamping arm includes a left clamping arm and a right clamping arm directly opposite the left clamping arm. A drive connection part for connecting to the powder container is provided on the connecting shaft. Thus, the device drive mechanism drives the material feeding fixing seat to move the clamping arm to the powder container, connecting the connecting shaft to the powder container. The clamping drive mechanism drives the clamping arm to clamp the powder container and move it to the synthesis cup. Then, the rotary drive mechanism drives the connecting shaft to rotate, thereby driving the powder container to automatically feed material. This method is not only highly efficient but also has high feeding accuracy.

[0105] In this specific embodiment, the automatic material feeding drive device further includes a positioning pin 66. The positioning pin 66 is disposed on the material feeding fixing seat 61 and located below the material feeding fixing seat. The positioning pin 66 is inserted into the clamping positioning part 324 to position the powder container, thereby preventing the powder container from rotating relative to the clamping arm after the clamping arm clamps the powder container.

[0106] In this specific embodiment, the automatic material feeding drive device further includes a position detection module 67. The position detection module 67 is mounted on the material feeding fixing seat and connected to the rotary drive mechanism. The position detection module detects the angular position of the connecting shaft, and before each time the rotary drive mechanism drives the connecting shaft to connect with the powder container, the position detection module outputs a control signal to the rotary drive mechanism based on the detected position. The rotary drive mechanism then drives the connecting shaft to rotate to a set initial angle based on the control signal. The position detection module allows adjustment of the initial angle of the connecting shaft before it connects with the powder container, ensuring that the driving connecting part and the rotating connecting part are aligned, allowing for smooth connection. The position detection module can be implemented using a photoelectric sensor.

[0107] In this specific embodiment, a detection plate 632 is provided on the outer surface of the connecting shaft 63, and a detection notch 6321 penetrating the upper and lower surfaces of the detection plate is provided on the detection plate. The position detection module is a photoelectric sensor, which includes a light emitter and a light receiver located above and below the detection plate, respectively. When the detection notch rotates to the position detection module, the light emitted by the light emitter passes through the detection notch and is received by the light receiver. At other positions, the light emitted by the light emitter is blocked by the detection plate, so the light receiver can determine the initial angle of the connecting shaft based on the received light signal.

[0108] In this specific embodiment, the clamping drive mechanism 64 includes a clamping drive motor 641, a clamping drive shaft 642, a drive gear 643, a left driven rack 644, and a right driven rack 645. Wherein:

[0110] The clamping drive shaft 642 is connected to the clamping drive motor and rotates under the drive of the clamping drive motor.

[0111] The drive gear 643 is fitted onto the clamping drive shaft and rotates with the clamping drive shaft.
