In order that the above objects, features and advantages of the utility model will be more clearly understood, a further description of the utility model will be made. The embodiments of the present utility model and the features in the embodiments may be combined with each other without collision.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may be practiced otherwise than as described herein; it is apparent that the embodiments in the specification are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1 to 3, a sample pretreatment system according to an embodiment of the present utility model includes a first loading and unloading mechanism 10, a gripping mechanism 40, a body clamping mechanism 50, a pipetting mechanism 60 and a housing 70.

The first loading and unloading mechanism 10 is used for finishing loading and unloading of the tray 20 for storing the material pipe, the first loading and unloading mechanism 10 comprises a first drawing structure 30, and the first drawing structure 30 is used for placing the tray 20 and can drive the tray 20 to move along a preset direction. The preset direction is the Y-axis direction shown in FIG. 3. The clamping mechanism 40 is used for clamping the material pipe from the first feeding and discharging mechanism 10 and driving the material pipe to move between the feeding and discharging stations and the liquid taking station. The body gripping mechanism 50 is used to grip or release a tube that is moved to the tapping station. The pipetting mechanism 60 comprises a pipetting assembly 61 for moving liquid in the tube of the pipetting station to a specified position. As shown in fig. 2, the first loading and unloading mechanism 10, the clamping mechanism 40, the bottle body clamping mechanism 50 and the pipetting mechanism 60 are all located in the outer cover 70, the outer cover 70 is provided with a first openable door 71, and the position of the first door 71 and the opening of the first door 71 correspond to the first pull-out structure 30.

According to the sample pretreatment system provided by the utility model, the openable first door body 71 is arranged on the outer cover 70, and the first pull-out structure 30 which is arranged corresponding to the first door body 71 is arranged on the first loading and unloading mechanism 10, in the working process, the loading and unloading process can be completed by opening the first door body 71 and pulling the corresponding first pull-out structure 30, so that the machine can be stopped without stopping or in a short time, the working efficiency is ensured, and the requirement of rapid detection is further met.

As shown in fig. 4, the first pull-out structure 30 includes a first sliding base plate 31 and a first carrier 32 disposed above the first sliding base plate 31, the tray 20 is placed on the first carrier 32, and the first carrier 32 is slidably engaged with the first sliding base plate 31 along a predetermined direction. Because the first pull-out structure 30 is opposite to the first door 71, when the tray 20 is replaced, the corresponding first door 71 can be opened, and the first carrier 32 is pulled to drive the tray 20 to move along the direction towards the first door 71 until the tray 20 extends out of the outer cover 70, so that the tray 20 is convenient to replace. Further preferably, a first buckle 322 is disposed on a side of the first carrier 32 near the first door 71, so that a worker can perform the pulling operation by the first buckle 322, thereby increasing the convenience of operation.

As shown in fig. 4 and 5, the first loading and unloading mechanism 10 further includes a first base 11 and a first linear module 12. The first linear module 12 is arranged on the first base 11, and the first base 11 is arranged on the frame, wherein an arc hole can be formed in the first base 11, the first base 11 is arranged on the frame through the arc hole by a fastener, the position of the whole first feeding and discharging mechanism 10 can be adjusted through the arc hole, and the position of the clamping jaw of the first feeding and discharging mechanism 10 and the clamping jaw of the clamping mechanism 40 are opposite. The first linear module 12 is configured to drive the first sliding substrate 31 to move along a predetermined direction. Under this design, the stroke of the tray 20 is divided into two sections, and the first section of stroke drives the first sliding substrate 31 to move towards the first door 71 through the first linear module 12 until the first sliding substrate 31, the first bearing member 32 located above the first sliding substrate 31, and the tray 20 move to a position inside the housing 70 near the first door 71. At this time, the first linear module 12 stops working, the worker opens the first door 71, and pulls the first buckle 322 by hand, so as to pull the first carrier 32 and the tray 20 to extend out of the outer cover 70, thereby completing the replacement process of the tray 20, improving the loading and unloading efficiency, increasing the stroke of the tray 20, and increasing the convenience of operation. In addition, the tray 20 has 8 holes along the Y axis, and the gripping mechanism 40 can only grip 4 tubes at a time and can only move along the X axis, so that the movement of the tray 20 along the Y axis can ensure that the gripping mechanism 40 can grip another 4 tubes.

The side of the first carrier 32 far from the first door body 71 of the housing 70 is connected with the first base 11 through a limiting mechanism 13. The position of the first bearing piece 32 in the non-reloading state is limited by the limiting mechanism 13, so that the first bearing piece 32 is prevented from moving in the working process, and the limitation of the first bearing piece 32 can be relieved by the limiting mechanism 13 in the reloading state, so that the first linear module 12 can conveniently drive the first linear module 12 and the first bearing piece 32 to move. Further preferably, one side of the first carrier 32 far away from the first door body 71 of the housing 70 is connected with the first sliding substrate 31 on the first base 11 through the limiting mechanism 13, wherein the first sliding substrate 31 is positioned through the first linear module 12, and the first carrier 32 and the first sliding substrate 31 are positioned through the limiting mechanism 13, so that the stability of the first carrier 32 can be ensured.

And the first bearing member 32 can be separated from the first base 11 or the first sliding substrate 31 under the action of external force.

In other embodiments, the limiting mechanism 13 may also be a buckle assembly, and specifically may include a slot disposed on the first carrier 32 and a buckle disposed on the first base 11 or the first sliding substrate 31, where the slot is matched with the buckle.

When the buckle is disposed on the first base 11, the first bearing member 32 can be driven to attach to or detach from the first base 11 by the movement of the first linear module 12.

Therefore, the specific setting mode of the limiting mechanism 13 is not limited, and only the setting of the limiting mechanism 13 needs to be ensured so that the first linear module 12 is disconnected when driving the first sliding substrate 31 and the first bearing member 32 to move, thereby avoiding affecting the work of the first linear module 12.

Since the second pull structure 90 is opposite to the second door 72, when the cartridge 81 and/or the target container 82 are replaced, the corresponding second door 72 can be opened, and by pulling the second carrier 92, the second carrier 92 can drive the cartridge 81 and/or the target container 82 to move along the direction towards the second door 72 until the cartridge 81 and/or the target container 82 protrudes out of the housing 70, so that replacement of the cartridge 81 and/or the target container 82 is facilitated. Further preferably, a second buckle 922 is disposed on a side of the second bearing member 92 close to the second door 72, and a worker can perform the pulling operation through the second buckle 922, so as to increase the convenience of operation.

The second linear module 84 is disposed on the second base 83, and the second base 83 is disposed on the frame, and the second linear module 84 is used for driving the second sliding substrate 91 to move along a predetermined direction. In this design manner, the stroke of the magazine 81 and/or the target container 82 is divided into two sections, and the first section of stroke drives the second sliding substrate 91 to move towards the second door 72 through the second linear module 84 until the second sliding substrate 91 and the second bearing 92 above the second sliding substrate 91 and the magazine 81 and/or the target container 82 move to a position inside the housing 70 near the second door 72. At this time, the second linear module 84 stops working, the worker opens the second door 72, and pulls the second bearing member 92 and the material box 81 and/or the target container 82 out of the outer cover 70 by pulling the second button 922, so as to complete the replacement process of the material box 81 and/or the target container 82, improve the loading and unloading efficiency, increase the travel of the material box 81 and/or the target container 82, and increase the convenience of operation.
