[0026] In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "center", "upper", "lower", "front", "back", "left", "right", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] As attached Figures 1 to 14As shown, the utility model provides a code scanning mechanism of a specimen conveying device, the code scanning mechanism 4 includes an industrial computer controller 41, a code scanning lens 42 and a specimen rolling device 43, the code scanning lens 42 is arranged above the specimen rolling device 43; the specimen rolling device 43 includes a second motor 431, a gantry 432, a rolling bracket 433, an active roller 434, a driven roller 435 and a fourth cylinder 436, the gantry 432 is connected to the frame 1, the second motor 431 is connected to the gantry 432, the active roller 434 is connected to the output shaft of the second motor 431, the driven roller 435 is connected to the rolling bracket 433, and the driven roller 435 is arranged in parallel with the active roller 434, the fourth cylinder 436 is connected to the frame 1, and the output shaft of the fourth cylinder 436 is connected to the rolling bracket 433 Next; it can be understood that when the specimen is placed in the position to be scanned, the barcode scanning lens 42 may not be able to scan the barcode or QR code on the specimen smoothly, so the specimen rolling device 43 is needed to roll the specimen so that the barcode scanning lens 42 can smoothly scan the barcode on the specimen. The principle is that in the initial state, the distance between the active roller 434 and the driven roller 435 is smaller than the diameter of the specimen, and the specimen can be lifted by the active roller 434 and the driven roller frame 435. The second motor 431 drives the active roller 434 to rotate, thereby driving the specimen to rotate. After the barcode scanning lens 42 scans the code successfully, the rolling bracket 433 is driven by the fourth cylinder 436 to drive the driven roller 435 away from the active roller 434, and the specimen falls from between the active roller 434 and the driven roller 435 to the next station of the specimen conveying device; a scanning solution is provided for the automation of the specimen conveying device.

[0029] Preferably, the code scanning mechanism 4 also includes a discharge device 44, which is arranged between the plate elevator 3 and the specimen rolling device 43; the discharge device 44 is used to control the number of specimens entering the rolling device to avoid multiple specimens entering the rolling device at the same time, thereby reducing the possibility of errors.

[0030] Preferably, the discharge device 44 includes a sixth cylinder 441, a material blocking plate 442 and a material discharge plate 443, the sixth cylinder 441 is connected to the frame 1, the material blocking plate 442 is connected to the output shaft of the sixth cylinder 441, and the material discharge plate 443 is arranged below the material blocking plate 442; the material blocking plate 442 and the sixth cylinder 441 are used to control the number of specimens entering the rolling device, and the material discharge plate 443 is inclined toward the rolling device to facilitate the specimens to flow to the rolling device for scanning.

[0031] Preferably, the discharge device 44 also includes a reference optical fiber 444, which is arranged on the two side plates of the gantry 432; the reference optical fiber 444 is used to sense whether the blocking plate 442 has blocked a specimen, if so, the loading (specimen) is suspended, if not, a specimen is lifted up to the blocking plate 442 to prevent the specimen from accumulating at the blocking plate 442, and when the blocking plate 442 discharges the material, two or more specimens are placed at the rolling device.

[0032] The specimen conveying device equipped with the code scanning mechanism of the utility model comprises a frame 1 and a hopper 2 arranged on the frame 1, a plate elevator 3, a code scanning mechanism 4 and a specimen conveying mechanism 5; the code scanning mechanism 4 comprises an industrial computer controller 41, a code scanning lens 42 and a specimen rolling device 43, the specimen rolling device 43 is arranged on one side of the plate elevator 3, the plate elevator 3 is used to lift the specimen to the specimen rolling device 43, and the code scanning lens 42 is arranged above the specimen rolling device 43; the specimen conveying mechanism 5 is arranged on the side of the code scanning mechanism 4 away from the plate elevator 3, the specimen conveying mechanism 5 comprises a transmission pipeline 51, a pushing device 52 and a driving device, the pushing device 52 is used to push the scanned specimen to the transmission pipe 51, and the driving device is used to drive the specimen in the transmission pipe 51 to the target department; with the above structure, one end of the transmission pipe 51 is arranged on this machine, and the other end extends to the target department through the building; the specimen collector puts the collected specimen into the hopper 2, and transmits the specimen to the specimen rolling device 43 through the plate elevator 3, so that the scanning lens 42 can smoothly scan the information code on the specimen, and then pushes the specimen to the transmission pipe 51 through the pushing device 52, and finally transports the specimen 100 along the pipe to the target department through the driving device; in this way, the automated specimen delivery is completed, which greatly reduces the labor cost and the probability of the specimen being sent to the wrong target department.

[0033] Preferably, it can be understood that the specimen is in a flat state when being uploaded by the plate elevator 3. In order to reduce the volume of the device and facilitate the installation of the transmission pipeline 51, it is necessary to turn the specimen in the flat state into a vertical state. The specimen transmission mechanism 5 also includes a specimen steering device 53, and the specimen steering device 53 includes a specimen steering wheel 531 and a first cylinder 532. The specimen steering wheel 531 is provided with a specimen accommodating hole 5311, and the driving shaft of the first cylinder 532 is connected to the specimen steering wheel 531; first, the specimen accommodating hole 5311 on the specimen steering wheel 531 is also in a flat state. Under the drive of the pushing device 52, the scanned specimen is pushed into the specimen accommodating hole 5311, and then, the specimen steering wheel 531 is driven by the first cylinder 532 to rotate 90 degrees, so that the outlet of the specimen accommodating hole 5311 is aligned with the transmission pipeline 51, and finally, the specimen is driven to the target department by the driving device.

[0034] Preferably, the specimen steering device 53 also includes a fifth cylinder 533 and a bogie 534, the specimen steering wheel 531 is arranged in the bogie 534, the specimen accommodating hole 5311 is a through hole, the fifth cylinder 533 and the bogie 534 are connected, and when the specimen accommodating hole 5311 is in a vertical state, the output shaft of the fifth cylinder 533 can extend into the specimen accommodating hole 5311; the specimen is placed in the specimen accommodating hole 5311, and then transmitted to the target department through the transmission pipe 51. Since the specimen steering wheel 531 needs to be rotated to adjust the position of the specimen, it is impossible for the transmission pipe 51 to achieve seamless docking with the specimen accommodating hole 5311. When the driving device is driven, the transmission pipe 51 and the specimen steering wheel 531 are connected. The gap between the two parts will cause air leakage, which will increase the load of the driving device and sometimes the specimen cannot be smoothly transmitted to the target department. For this reason, an auxiliary device is provided, namely the fifth cylinder 533 in this embodiment; its working process is as follows: first, the output shaft of the fifth cylinder 533 is lowered to the lowest position, and when the specimen accommodating hole 5311 is in a flat state, the specimen is pushed into the specimen accommodating hole 5311 by the pushing device 52, and then the specimen steering wheel 531 is driven by the first cylinder 532 to rotate 90 degrees. Since the output shaft of the fifth cylinder 533 is supported below, the specimen will not fall out of the specimen accommodating hole 5311, and then the specimen is pushed into the transmission pipe 51 by the output shaft of the fifth cylinder 533, so that the driving device can be smoothly used to transmit the specimen to the target department.

[0035] Preferably, it can be understood that different test items of specimens are in different departments. In order for the device to be able to transmit specimens to multiple target departments, the present application provides two sets of solutions;

[0036] In the first scheme, the device transports specimens to two target departments. The driving device and the specimen steering device 53 are respectively provided with two sets, and a corresponding set of driving device and a set of specimen steering device 53 are respectively provided on both sides of the pushing device 52. Through a set of driving device and a set of specimen steering device 53 respectively provided on both sides of the pushing device 52, the specimens can be transported to the two target departments.

[0037] In the second scheme, different specimens need to be subjected to different tests, such as routine blood tests, blood type, erythrocyte sedimentation rate, reticulocyte, blood biochemistry, blood immunity and serum tests, which cannot be satisfied at the same time in the first scheme. Therefore, it is necessary to make the device capable of one-to-many transmission. For example, four sets of driving devices and four sets of specimen steering devices 53 are provided, and every two sets are provided on a central axis. The device also includes a specimen moving device 54, and the pushing device 52 is connected to the output shaft of the specimen moving device 54, and is used to move the specimen on multiple central axes. For the convenience of description, a set of driving devices that cooperate with each other is used to move the specimen on multiple central axes. The moving device and a set of specimen steering devices 53 are called a set of steering units. The four sets of steering units are arranged in a rectangular shape on a plane. In this way, the specimen and the pushing device 52 need to be moved relative to the steering unit by the specimen moving device 54. For example, the first set of steering units and the second set of steering units are on a straight line, and the third set of steering units and the fourth set of steering units are on another straight line. The specimen and the pushing device 52 need to be moved to another straight line by the specimen moving device 54; in this way, the specimen transmission of the device to multiple target departments is completed. By analogy, the steering units can be six sets, eight sets, etc. Of course, the steering units can be an odd number greater than two sets, such as three sets, five sets, etc., and the first two sets are arranged in a straight line, and the last set can be arranged in a row with the others, and the other end can be empty.

[0038] Preferably, the pushing device 52 includes a first motor 521, a screw rod 522, a third cylinder 523, a push plate 524 and a specimen to be pushed plate 525, the screw rod 522 is connected to the driving shaft of the first motor 521, the third cylinder 523 is connected to the screw rod 522 in a transmission connection, the push plate 524 is connected to the driving shaft of the third cylinder 523, the specimen to be pushed plate 525 is located below the push plate 524, and is used to receive the specimen after scanning the code; the transverse cross-section of the specimen to be pushed plate 525 is V-shaped or U-shaped, and the specimen is located at the specimen to be pushed When the specimen is on the delivery plate 525, it can be ensured that the specimen will not roll around; after the specimen is scanned, it can be known into which specimen receiving hole the specimen is to be pushed. When the pushing device 52 is working, in the initial state, the third cylinder 523 lifts the pushing plate 524. When the specimen needs to be pushed to the specimen receiving hole 5311 on one side, the first motor 521 drives the third cylinder 523 to the other side of the specimen through the screw rod 522, and then the third cylinder 523 drives the pushing plate to move downward, so that the pushing plate 525 can push the specimen to the predetermined specimen receiving hole 5311 under the drive of the first motor.

[0039] Preferably, each of the transmission pipelines 51 includes an equipment section 511 and a building section 512, and a partition plate 514 driven by a second cylinder 513 is provided between the equipment section 511 and the building section 512, wherein the equipment section 511 is a pipeline at one end provided on the equipment, and the building section 512 is a pipeline arranged between buildings and extending from the equipment to each target department; when it is necessary to block a certain transmission pipeline 51, the partition plate 514 is driven by the second cylinder 513 to extend between the equipment section 511 and the building section 512, otherwise, the partition plate 514 is driven by the second cylinder 513 to withdraw from between the equipment section 511 and the building section 512.
