After the sample barrel is packaged, the translation assembly 104 pushes the sample barrel into the buffer unit, and the second reduction motor 108b moves the sample barrel to the barrel taking port. A sensor is provided in the sample barrel buffer assembly 108, and when the number of sample barrels cached reaches the set number of 3, an alarm will be issued to prompt manual barrel taking.

[0042] When in use, a person manually places the password barrel 102 on the first roller line 103a, and the first reduction motor 103c drives the roller to transport the password barrel 102 to the corresponding position. During this period, a swing arm blocking component reads and judges the information of the password barrel 102, and a cache position is provided to cache and place unqualified sample barrels. An alarm is issued through the sensor to prompt a person to come and handle it. When the password barrel 102 on the first roller line 103a reaches the specified position, the rodless cylinder 104b drives the barrel push arm 104c connected to the linear rail and the slider. The barrel push arm 104c hooks the password barrel 102 body and brings the password barrel 102 to the next workstation. After the action is completed, the rodless cylinder 104b resets and waits for the next password barrel 102 to enter the specified working position;

[0043] The turntable 105a is provided with 8 stations for placing the electronic password barrel 102. The password barrel 102 can realize functions such as reading and writing codes, opening the lid, loading, weighing, and closing the lid in this working module. The rotation uses an 8-station divider to make the rotation more stable. The first reduction motor 103c and the second reduction motor 108b are both equipped with brakes to make the positioning more accurate. A dynamic load weighing module is used, which is adjustment-free, convenient, durable, and has precise scales. When the password barrel 102 is opened, the lifting cylinder 106b extends downward. After reaching the limit, the clamping claw cylinder 107a moves to clamp the lid. The 4 probes 106g on it contact the lid. The probe 106g is powered on to unlock the lid, achieving the purpose of automatic opening. After unlocking, the barrel lid is lifted. Conversely, when closing the lid, the lifting cylinder 106b extends downward to put the barrel lid into the barrel body and then powers on to lock it.

[0044] The sample barrel cache assembly is composed of a second roller line 108a and a second reduction motor 108b. After the sample barrel is packaged, the translation assembly 104 pushes the sample barrel into the cache unit, and the second reduction motor 108b moves the sample barrel to the barrel taking port. A sensor is provided in the sample barrel cache assembly 108. When the number of sample barrels cached reaches the set number of 3, an alarm will be issued to prompt manual barrel taking.

[0045] The remaining structures are the same as those of Example 1.

[0046] Example 3, reference Figures 3-4, which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the switch assembly 201 includes an extension rod 201a arranged on the bracket 106a, and a proximity limit switch 201b arranged on the extension rod 201a; wherein the extension rod 201a and the bracket 106a are fixedly connected, the proximity limit switch 201b is arranged on the side of the extension rod 201a close to the gripper finger 107b, and the proximity limit switch 201b is arranged at the lowest point on the extension rod 201a, when the lifting cylinder 106b drives the gripper assembly 107 to descend to After limiting, the gripper finger 107b approaches the proximity limit switch 201b. After the proximity limit switch 201b senses the gripper finger 107b, it starts the solenoid valve 202b in the air supply assembly 202, thereby automatically purging the barrel cover; when the gripper cylinder 107a drives the gripper finger 107b to clamp the barrel cover, the sensing gap between the gripper finger 107b and the proximity limit switch 201b increases, and the solenoid valve 202b automatically closes and stops purging; the proximity limit switch 201b needs to be adjusted in advance before use. The sensing gap with the gripper finger 107b during the descent process.

[0047] Furthermore, the air supply assembly 202 includes a connecting air pipe 202a disposed on the air supply pipe 106c, and a solenoid valve 202b disposed on the connecting air pipe 202a; wherein the connecting air pipe 202a is connected to the air supply pipe 106c, and the solenoid valve 202b is controlled by the proximity limit switch 201b.

There are multiple purge nozzles 203d, and the lowest height of the purge nozzle 203d on the probe plate 106f is higher than the height of the probe 106g, which does not affect the normal use of the probe 106g. At the same time, by setting multiple purge nozzles 203d, the purge range of the barrel cover can be expanded.

[0049] When in use, when the lifting cylinder 106b extends downward and the gripper finger 107b senses the proximity limit switch 201b, the proximity limit switch 201b is activated, the solenoid valve 202b is turned on, and the existing source is transported to the connecting air pipe 202a through the air supply pipe 106c, and then passes through the air supply cavity 203a, the air supply channel 203b and the air supply collection cavity 203c, and finally sprayed out through the purge nozzle 203d to purge the barrel cover. When the gripper finger 107b is clamped, the sensing gap with the proximity limit switch 201b increases, and the solenoid valve 202b is automatically closed to stop purging.
