The bottom of each of the two clamping plates is fixedly provided with a plurality of first clamping needles and a plurality of second clamping needles. The two first clamping needles and the two second clamping needles form a group. The number of the first clamping needles is the same as that of the second clamping needles.

[0013] In a possible design, the Y-axis moving mechanism comprises a Y-axis box body, a first motor and a first screw rod. One side of the Y-axis box body is fixedly connected to one side of the partition plate. One side of the first motor is fixedly connected to the inner wall of one side of the Y-axis box body. One end of the first screw rod is fixedly connected to the output end of the first motor, and the other end is rotationally connected to the inner wall of one side of the Y-axis box body. The inner wall of one side of the Y-axis box body is slidingly connected to a first moving block. The inner wall of one side of the first moving block is embedded with a first screw rod nut, and the first screw rod nut is threadedly connected to the first screw rod.

[0014] In a possible design, the X-axis moving mechanism comprises an X-axis box body, a second motor and a second screw rod.

One end of the third screw rod is fixedly connected to the output end of the third motor, and the other end is rotationally connected to the inner wall of one side of the Z-axis box body.

[0016] In one possible design, a fourth motor for driving the gripper to rotate horizontally is fixedly mounted on one side of the connecting plate, and the output end of the fourth motor is fixedly connected to the top of the fixed base.

[0017] In this application, during use, the carrier containing the cryopreservation tubes is placed on a tray in preparation for inkjet printing. When it is necessary to move the gripper back and forth, the first motor is started. The output of the first motor drives the first lead screw to rotate, which in turn moves the first moving block back and forth. Simultaneously, it drives the X-axis moving mechanism, the Z-axis moving mechanism, and the gripper to move back and forth, thus allowing the gripper to move back and forth to hold the cryopreservation tubes. When it is necessary to move the gripper left and right, the second motor is started. The second motor drives the second lead screw to rotate, which in turn moves the second moving block left and right. The movement of the second moving block drives the Z-axis moving mechanism and the gripper to move, thus allowing the gripper to move left and right. The grippers move left and right to facilitate clamping the cryovials. After the first and second clamping pins of the grippers move above the cryovials, the third motor is activated. The output shaft of the third motor drives the third lead screw to rotate. The rotation of the third lead screw drives the third moving block and the connecting plate to move. The movement of the connecting plate drives the grippers to move, thus allowing the grippers to be adjusted up and down. This allows the first and second clamping pins at the bottom of the two clamping plates to extend into the gap formed by the arc of the adjacent tubes. The fifth motor is then activated. The output of the fifth motor drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw brings the two mounting plates closer together, clamping the cryovials through the first and second clamping pins. Figure FourAs shown), a column of cryovials is clamped, the carrier is lifted, and the first cryovial in this column is brought close to the nozzle. The Z-axis moves up and down, and the nozzle prints the code. The second cryovial in this column is then printed, and so on, until all cryovials in the column are printed. The fourth motor 16 is then started, and its output drives the gripper and the held cryovials to rotate horizontally by 180 degrees. The cryovials are then brought close to the nozzle again for printing. After printing, the horizontal rotation mechanism rotates 180 degrees, and the X-axis, Y-axis, and Z-axis moving mechanisms, along with the gripper, work together to return the column of cryovials to its original position. The above steps are then repeated for printing other columns. The guide rail can be an electric guide rail or an electric slide (electric slide...). The model number is AOMING AMB45-S10 (the specific model and specifications can be selected according to actual needs). It can automatically extend outside the equipment to work in conjunction with other equipment to achieve automatic sample loading. The first, second, third, fourth, and fifth motors require an external controller for control and an external power supply for power supply. The first, second, third, fourth, and fifth motors can be stepper motors (rotary-compatible), conical rotor motors (self-locking), or other types of motors, depending on actual needs. The material type and specifications of the first, second, third, and bidirectional lead screws can be selected according to actual needs.

[0018] In this utility model, the automatic positioning double-sided inkjet printer for cryopreservation tubes uses grippers and the output end of the fifth motor to drive a bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes the two mounting plates to move closer to each other. The cryopreservation tubes are clamped by the first clamping pin and the second clamping pin. The grippers are designed as pins, and the pins (two first clamping pins and two second clamping pins) can just extend into the gap formed by the arc of the adjacent tubes, which makes it easy to clamp the cryopreservation tubes.

[0019] In this utility model, the automatic positioning double-sided inkjet printer for cryopreservation tubes uses a Y-axis moving mechanism to start a first motor when the gripper needs to move back and forth. The output end of the first motor drives the first lead screw to rotate, thereby driving the first moving block to move back and forth. At the same time, it drives the X-axis moving mechanism, the Z-axis moving mechanism, and the gripper to move back and forth, so that the gripper can move back and forth to hold the cryopreservation tube.

[0020] In this utility model, the automatic positioning double-sided inkjet printer for cryopreservation tubes uses an X-axis moving mechanism to start a second motor when the gripper needs to move left or right. The second motor drives the second lead screw to rotate, which in turn drives the second moving block to move left or right. The movement of the second moving block drives the movement of the Z-axis moving mechanism and the gripper, thereby enabling the gripper to move left or right, which facilitates the gripper to hold the cryopreservation tube.

[0021] In this invention, the automatic positioning double-sided inkjet printer for cryopreservation tubes starts a third motor through a Z-axis moving mechanism. The output shaft of the third motor drives the third lead screw to rotate. The rotation of the third lead screw drives the movement of the third moving block and the connecting plate. The movement of the connecting plate drives the movement of the gripper, thereby allowing the gripper to be adjusted up and down.

[0022] In this invention, the grippers facilitate the clamping of cryopreservation tubes, and the Y-axis, X-axis, and Z-axis moving mechanisms allow the grippers to move in multiple directions for easy clamping. Attached Figure Description
