[0032] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0033] The core of the utility model discloses a sample rack information identification device, and the movement mechanism can drive the scanning device to move in two directions in the horizontal plane, can scan and identify multiple sample racks, has large scanning range, lower cost and high scanning and identifying efficiency.

[0034] In addition, the utility model provides a sample tube transfer module comprising the sample rack information identification device.

[0035] The utility model discloses a sample rack information identification device, which comprises:

[0036] The scanning device 2 is used for scanning and identifying the sample rack to obtain sample rack information.

[0037] The movement mechanism 1 is connected with the scanning device 2 at the moving end to drive the scanning device 2 to move in two directions in the horizontal plane.

[0038] The control device is signal connected with the scanning device 2 and the movement mechanism 1.

[0039] It should be noted that the sample rack information includes the code of the sample rack, the distribution of the sample tubes in the sample rack 4, whether the sample tubes are arranged at each hole position of the sample rack 4, the type of the sample tubes at each hole position, the type of the caps of the sample tubes, etc.

[0040] Please refer to Figure 4 The sample rack 4 is arranged in an array in the sample loading and unloading platform module 20, and a plurality of sample tubes 5 are placed in the sample rack 4.

[0041] The specific type, shape and size of the sample rack identification area 41 are determined according to the actual production needs, and will not be described here.

[0042] Due to the array arrangement of the sample rack 4, the sample rack identification area 41 is arranged on the side surface of the sample rack 4 that is not opposite to the adjacent sample rack 4, for example Figure 4 The sample rack identification area 41 is arranged on the end surface of the sample rack 4.

[0043] The sample rack identification area 41 can be arranged on the central side surface of the sample rack 4, or on the end portion of the side surface of the sample rack 4.

[0044] The scanning device 2 is used for scanning and identifying the sample rack 4 to obtain corresponding sample rack information, and the structure and type of the scanning device 2 need to be determined according to actual production needs, such as the information identification mode of the sample rack identification area 41.

[0045] For example, when the sample rack identification area 41 is provided with a barcode, the scanning device 2 includes a barcode scanner for scanning and identifying the barcode; of course, the barcode can also be collected by a camera to obtain image information of the barcode, and then the control device analyzes and processes the image information to obtain corresponding information.

[0046] In order to simplify the structure of the scanning device 2, the scanning device 2 can be provided to only include a camera for collecting images of the sample rack 4.

[0047] The scanning device 2 is arranged at the moving end of the motion mechanism 1, and since the motion mechanism 1 can move in two directions in the horizontal plane, it can be understood that the moving end herein refers to the moving end of the last-stage motion mechanism of the motion mechanism 1.

[0048] The scanning device 2 can be connected to the moving end of the motion mechanism 1 through fasteners such as fastening bolts and connecting pins, or can be arranged on the moving end of the motion mechanism 1 through a mounting bracket, so as to avoid affecting the normal work of other structures such as the gripper 3 installed on the motion mechanism 1.

[0049] For example, please refer to Figure 1 The scanning device 2 is arranged on the side surface of the sliding base of the Z-axis motion mechanism 13 of the motion mechanism 1, so that the scanning device 2 is arranged opposite to the sample rack identification area 41 of the sample rack 4, so as to ensure the image scanning quality of the scanning device 2.

[0050] The motion mechanism 1 can drive the scanning device 2 to move in two directions in the horizontal plane, so the motion mechanism 1 has at least two translational degrees of freedom; the motion mechanism 1 can be provided as a linear motion mechanism such as an electric push rod or a linear motor, or can be provided as a transmission mechanism such as a driving motor and a ball screw structure or a synchronous belt mechanism.

[0051] The motion mechanism 1 and the scanning device 2 are both signal-connected to the control device, the control device can control the motion of the motion mechanism 1 to move the scanning device 2 to the vicinity of the sample rack 4 to be scanned, and can also receive image information transmitted by the scanning device 2 and process, obtain and store corresponding sample rack information.

[0052] In the embodiment, the motion mechanism 1 can drive the scanning device 2 to move in two directions in the horizontal plane, so that the scanning device 2 can scan and identify the sample rack identification area 41 of the plurality of sample racks 4, the scanning range is large, the cost is low, and the sample rack information scanning efficiency is significantly improved.

[0053] On the basis of the above embodiment, in order to facilitate the motion control of the motion mechanism 1, the motion mechanism 1 comprises an X-axis motion mechanism 11 and a Y-axis motion mechanism 12, the fixed end of the Y-axis motion mechanism 12 is arranged on the moving end of the X-axis motion mechanism 11, and the motion direction of the Y-axis motion mechanism 12 is perpendicular to the motion direction of the X-axis motion mechanism 11.

[0054] The structures of the X-axis motion mechanism 11 and the Y-axis motion mechanism 12 can be the same or different. When the moving end of the X-axis motion mechanism 11 moves, the Y-axis motion mechanism 12 and the scanning device 2 can be driven to move synchronously. When the moving end of the Y-axis motion mechanism 12 moves, the scanning device 2 can be driven to move synchronously.

[0055] In the embodiment, the X-axis motion mechanism 11 and the Y-axis motion mechanism 12 are arranged orthogonally, which is more conducive to the motion control of the control device than the inclined arrangement of the X-axis motion mechanism 11 and the Y-axis motion mechanism 12.

[0056] On the basis of the above embodiment, in order to facilitate the focusing of the scanning device 2 and improve the scanning quality, the motion mechanism 1 can further comprise a Z-axis motion mechanism 13, the fixed end of the Z-axis motion mechanism 13 is arranged on the moving end of the Y-axis motion mechanism 12, and the Z-axis motion mechanism 13 is used to drive the scanning device 2 to move up and down along the height direction.

[0057] The addition of the Z-axis motion mechanism 13 enables the scanning device 2 to move freely in a three-dimensional space, further increases the scanning range of the scanning device 2, and enables the scanning device 2 to adapt to scanning requirements of different heights, angles and depths, and more easily meet the scanning quality requirements in space-limited or complex environments.

[0058] In order to reduce the number of accessories and facilitate maintenance, the structures of the X-axis motion mechanism 11, the Y-axis motion mechanism 12 and the Z-axis motion mechanism 13 are usually the same, for example, please refer to Figure 1 The fixed ends of the X-axis motion mechanism 11, the Y-axis motion mechanism 12 and the Z-axis motion mechanism 13 are all provided with synchronous belt assemblies along the motion direction, the driving pulley of the synchronous belt assembly is sleeved on the output shaft of the driving motor, and the synchronous belt of the synchronous belt assembly is connected with the sliding base.

[0059] When the driving motor rotates, the driving pulley of the synchronous belt assembly is driven to rotate, and then the synchronous belt and the sliding base connected with the synchronous belt are driven to move along the motion direction, so as to drive the subsequent motion mechanism and the scanning device 2 to move synchronously.

[0060] Compared with the linear displacement mechanism such as the electric push rod and the linear motor, the cost of driving the synchronous belt assembly by the driving motor is low and easy to maintain, and at the same time, the transmission of the synchronous belt assembly is stable and accurate, and the noise and energy consumption are low.

[0061] Preferably, in order to ensure that the movement direction of each level of movement mechanism does not deviate, a guide device can be arranged at the fixed end of the X-axis movement mechanism 11, the Y-axis movement mechanism 12 and the Z-axis movement mechanism 13, and the guide device can be a linear guide rail, a linear guide rod or the like, and the sliding base is slidingly arranged on the guide device, so as to limit the movement direction of the sliding base by the sliding pair.

[0062] In addition to the sample rack information identification device, the utility model also provides a sample tube transfer module 10 comprising the sample rack information identification device disclosed in the above embodiment, which comprises the sample rack information identification device disclosed in the above embodiment and a gripper 3 for grabbing the sample tube 5, and the gripper 3 is arranged at the bottom of the moving end of the movement mechanism 1.

[0063] The movement mechanism 1 cooperates with the gripper 3 to realize the grabbing and transferring of the sample tube 5, and complete the transfer of the sample tube 5 in the sample loading and unloading process.

[0064] Considering the layout of the sample loading and unloading platform module 20 and the sample transmission track module, in order to shorten the transfer path of the sample tube 5 and facilitate the movement control of the movement mechanism 1, the movement mechanism 1 is preferably arranged at the top end of the rack of the pipeline sample loading and unloading system, and the movement mechanism 1 can move along the length direction and the width direction of the pipeline sample loading and unloading system.

[0065] In the embodiment, the gripper 3 for grabbing the sample tube 5 and the scanning device 2 are integrated on the same movement mechanism 1, which not only meets the movement needs of the scanning device 2 and the gripper 3, but also reduces the number of movement structures and the cost of the equipment, and enables the scanning result of the scanning device 2 to be combined with the movement position information of the sample tube 5, thereby realizing the dynamic tracking and positioning of the scanning structure.

[0066] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts of each embodiment can be referred to each other.

[0067] The sample tube transfer module and the sample rack information identification device provided by the utility model are described in detail above. The principles and implementation modes of the utility model are described by applying specific examples in this paper, and the description of the above embodiments is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and modifications can be made to the utility model without departing from the principles of the utility model, and these improvements and modifications also fall within the protection scope of the claims of the utility model.
