DETAILED DESCRIPTION

[0018] The following is a more detailed description of the implementation of the utility model in conjunction with the drawings and the figure marks, so that those skilled in the art can implement it after reading this specification. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0019] The utility model provides an in vitro diagnostic equipment code scanning device, including a sample tube rotating unit, a clamping unit and a code scanning unit. In the prior art, the in vitro diagnostic equipment is provided with a conveying track 40 for conveying a sample rack, and a sample tube loaded with a sample is placed on the sample rack, and a barcode is provided on one side of the sample tube. Figure 1 The sample tube rotating unit and the code scanning unit are respectively arranged on both sides of the conveying track 40. When code scanning is required, the clamping unit cooperates with the sample tube rotating unit to rotate the sample tube, and the code scanning is completed when the barcode faces the code scanning unit.

[0020] Specifically, the sample tube rotating unit includes a rotating motor 11 and an active roller 12 arranged on the output shaft of the rotating motor 11. The rotating motor 11 drives the active roller 12 to rotate. When the active roller 12 contacts the sample tube, the sample tube is driven to rotate under the action of friction. The active roller 12 is an elastic roller made of elastic materials such as rubber, which has a buffering effect on the sample tube. Furthermore, in other embodiments, the output shaft of the rotating motor 11 is connected to a telescopic rod, and the active roller 12 is arranged at the end of the telescopic rod to adjust the height of the active roller 12.

[0021] The clamping unit includes a bracket 25, a guide rail 21 disposed on the top of the bracket 25, a slider 22 slidably connected to the guide rail 21, a clamping arm 23 disposed on the slider, and a linear module for driving the slider to slide. The clamping arm 23 is rotatably connected to two driven rollers 24. Please refer to Figure 1 , the clamping arm 23 extends to one side of the code scanning unit, the active roller 12 is between the driven roller 24 and the bracket 25, and the driven roller 24 and the active roller 12 are provided with a gap, and the conveying track 40 transports the sample tube through the gap. The linear module can refer to the relevant technology; in this embodiment, the linear module includes a driving wheel 261 and a driven wheel 262 rotating relative to the bracket 25, a synchronous belt 263 connected between the driving wheel 261 and the driven wheel 262, a motor 264 for driving the driving wheel 261 to rotate, and a connecting arm 265 connected between the slider 22 and the synchronous belt 263, so as to realize the reciprocating sliding of the slider 22 relative to the guide rail 21. The bracket 25 is also provided with a position sensor, which can be a photoelectric sensor, arranged at the bottom of the connecting arm, and the stroke of the slider 22 is judged with reference to the connecting arm 265.

[0022] When the barcode needs to be scanned, the linear module drives the slider 22, the clamping arm 23 and the driven roller 24 to move a short distance to the side of the active roller 12. The driven roller 24 applies pressure to clamp the sample tube and the active roller 12. Then the active roller 12 drives the sample tube and the driven roller 24 to rotate to change the direction of the barcode on the sample tube.

[0023] Furthermore, in order to prevent the driven roller 24 from causing the sample tube to break or fall during the clamping process, this embodiment is also optimized. The slider 22 includes a bottom plate slidably connected to the guide rail 21, a support 221 disposed on the bottom plate, a transmission block that slides relative to the support 221 via a sliding shaft 222, the clamping arm 23 is connected to the transmission block, the sliding shaft 222 is parallel to the guide rail 21, and a buffer spring 223 is disposed between the transmission block and the support 221. During the clamping process, the buffer spring 223 can play a buffering role to prevent the slider 22 from traveling too long and causing excessive clamping force to damage the sample tube.

[0024] For details, please refer to Figure 2 The transmission block includes a main body 224 and two legs 225 respectively arranged on both sides of the main body 224, and the two parallel sliding shafts 222 are connected to the two legs 225; two supports 221 are arranged on the bottom plate, one of the supports 221 is arranged between the two legs 225, the two supports are parallel and the support 221 is slidably connected to the sliding shaft 222; the buffer spring 223 can be a compression spring, which is arranged between one leg 225 and a support 221; a limiting head 226 is arranged at the end of the sliding shaft 222.

[0025] The barcode scanning unit includes a barcode scanner 31 disposed on the side of the driven roller 24 away from the driving roller 12. The barcode scanner 31 is any commercially available barcode scanning device for identifying barcodes or two-dimensional codes. When the barcode on the sample tube is turned to the barcode scanner, the barcode scanner completes the barcode scanning.

[0026] The above are one or more embodiments of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
