Description

Technical Field

[0001] This utility model relates to the field of automated detection technology, specifically to a specimen rotation lifting and barcode scanning device. Background Technology

[0002] In the process of medical / laboratory specimen testing, there is a crucial step – scanning the specimen to read its information. The main existing technologies for this are as follows:

[0003] Roller-type clamping rotary barcode scanning: This method uses several rollers, with the left and right rollers moving towards the specimen, clamping the specimen, and then rotating the rollers to drive the specimen to rotate and scan the barcode. However, this method occupies a large space, the clamping force is difficult to control, and the failure rate is high.

[0004] Roller-type rotary barcode scanning: The specimen is placed flat on two close rollers (horizontally installed). After the rollers rotate, the specimen rotates due to its own weight and the friction generated with the rollers; thus, the barcode is scanned to read the specimen information. Although the control of this method is simple, its application scenarios are limited. It requires the specimen to be transferred horizontally to the rollers, which is not suitable for specimen inspection. The specimen also needs to be uprighted and then grasped and transferred to the subsequent mechanism. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a specimen rotation lifting and scanning device, which has the advantages of simple structure, wide application scenarios, and small space occupation. It solves the problems of large space occupation, complex structure, cumbersome mechanism operation, and high failure rate of roller clamping rotation scanning and roller-type rotation scanning.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned goals of simple structure, wide application scenarios, and small space occupation, this utility model provides the following technical solution: a specimen rotation lifting and barcode scanning device, comprising a drive device, a lifting plate, and a lead screw guide rail module. The lifting plate is connected to the lead screw of the lead screw guide rail module via bearings. The drive device is mounted on the lifting plate. A specimen lifting and rotating base is installed at the top of the lead screw of the lead screw guide rail module. A specimen lifting and rotating base pressing block is provided on the support of the lead screw guide rail module. A barcode reading device is provided on the support of the lead screw guide rail module.

[0009] When the drive device drives the lead screw guide module to lift the lifting plate and the specimen lifting and rotating base on it, the specimen lifting and rotating base will be squeezed by the specimen lifting and rotating base squeezing block during the lifting process to clamp the specimen. At this time, the specimen will be clamped and rotated by the specimen lifting and rotating base, and the code reading device will scan the specimen.

[0010] Preferably, the drive device is provided with a first drive wheel, the lead screw of the lead screw guide module is provided with a second drive wheel, and a synchronous belt is provided between the first drive wheel and the second drive wheel.

[0011] Preferably, the lifting plate is provided with a lifting guide column, and a lifting guide rod is inserted inside the lifting guide column. The bottom of the lifting guide rod is fixedly connected to the bracket of the lead screw guide rail module.

[0012] Preferably, the specimen lifting and rotating base compression block is divided into a specimen lifting and rotating base compression block left and a specimen lifting and rotating base compression block right.

[0013] Preferably, a specimen detection switch is provided on one outer side of the bracket of the lead screw guide module.

[0014] Preferably, the lifting plate is equipped with a sensor plate, and the bottom of the bracket of the lead screw guide rail module is equipped with a sensor switch.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a specimen rotation lifting and barcode scanning device, which has the following beneficial effects:

[0017] This specimen rotation and lifting barcode scanning device utilizes the coordinated operation of a drive unit, lifting plate, lead screw guide rail module, specimen lifting and rotating base, specimen, and barcode reading device. When a specimen detection switch detects a specimen, the drive unit drives a second drive wheel to rotate via a first drive wheel and a synchronous belt. As the second drive wheel rotates, the lead screw on the lead screw guide rail module also rotates and rises. Simultaneously, the lifting plate, guided by the lifting guide rod and lifting guide column, also rises. The specimen lifting and rotating base also rotates and rises synchronously. When the specimen lifting and rotating base passes the right and left sides of the specimen lifting and rotating base compression block, both blocks compress the top of the specimen lifting and rotating base, clamping the specimen and causing it to rotate. At this point, the specimen rises and rotates, and the barcode reading device begins to read the specimen information. After completion, the drive unit drives in the opposite direction, and all the mechanisms that have just risen return to their original positions before stopping, awaiting the next specimen. The lifting position is controlled by a sensor plate and a sensor switch. This achieves a simple structure, wide application scenarios, and small footprint. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 A specimen rotation lifting and barcode scanning device includes a drive unit 2, a lifting plate 4, and a lead screw guide rail module 9. The lifting plate 4 is installed at the top of the lead screw of the lead screw guide rail module 9. The drive unit 2 is installed on the outside of the lifting plate 4. A specimen lifting and rotating base 3 is installed at the top of the lead screw of the lead screw guide rail module 9, and the specimen lifting and rotating base 3 rotates together with the lead screw of the lead screw guide rail module 9. Specimen lifting and rotating base pressing blocks are arranged opposite each other on the two inner sides above the support of the lead screw guide rail module 9. A barcode reading device 1 is also installed above the support of the lead screw guide rail module 9. The drive unit 2 provides power to the device, and by driving the lead screw guide rail module 9, the lifting plate 4 and the specimen lifting and rotating base 3 connected to it move in a set manner to realize the rising, rotating, and subsequent lowering actions of the specimen 17. The lifting plate 4, as a connecting and bearing component, is installed at the top of the lead screw of the lead screw guide rail module 9, bearing the specimen lifting and rotating base 3, and also used to install the drive unit 2 and the sensing plate 6. The lead screw guide module 9 converts the power of the drive device 2 into the upward and rotating motion of the lifting plate 4, realizing the upward and rotating scanning of the specimen 17. The specimen lifting and rotating base 3 is used to place and fix the specimen 17 at specific times, and moves with the rise and fall of the lifting plate 4. The specimen lifting and rotating base compression blocks are arranged in pairs on the two inner sides above the support of the lead screw guide module 9. When the specimen lifting and rotating base 3 rises to a certain position, they will squeeze the specimen lifting and rotating base 3 from both sides, so that the specimen 17 is firmly clamped on the specimen lifting and rotating base 3 and rotates under the drive of the specimen lifting and rotating base 3, ensuring that the specimen 17 remains stable during the scanning process, so as to facilitate the barcode reading device 1 to obtain accurate information. The barcode reading device 1 is used to read the barcode, QR code or other identification information on the specimen 17.

[0023] When the drive device 2 drives the lead screw guide module 9 to lift the lifting plate 4 and the specimen lifting and rotating base 3 on it, the specimen lifting and rotating base 3 will be squeezed by the specimen lifting and rotating base squeezing block during the lifting process to clamp the specimen 17. At this time, the specimen 17 will be clamped and rotated by the specimen lifting and rotating base 3, and the code reading device 1 will scan the code of the specimen 17.

[0024] The drive unit 2 is equipped with a first drive wheel 5, and the lead screw of the lead screw guide module 9 is equipped with a second drive wheel 11. A synchronous belt 8 is provided between the first drive wheel 5 and the second drive wheel 11. Through the cooperation of the first drive wheel 5, the second drive wheel 11 and the synchronous belt 8, the rotational motion of the drive unit 2 is transmitted to the rotational motion of the lead screw on the lead screw guide module 9, thereby realizing the upward motion of the lifting plate 4 and the components on it.

[0025] A lifting guide column 13 is provided on the lifting plate 4, and a lifting guide rod 12 is inserted inside the lifting guide column 13. The bottom of the lifting guide rod 12 is fixedly connected to the bracket of the lead screw guide module 9. The lifting guide column 13 and the lifting guide rod 12 provide guidance for the up and down movement of the lifting plate 4, ensuring that the lifting plate 4 can rise and fall smoothly in a fixed direction, avoiding swaying or deviation during movement, and ensuring the stability and accuracy of the specimen lifting and rotating base 3 and the specimen 17 during the lifting process.

[0026] The specimen lifting and rotating base compression block is divided into a left compression block 15 and a right compression block 14. When the specimen lifting and rotating base 3 rises to a specific position, the left and right compression blocks 15 and 14 squeeze the specimen lifting and rotating base 3 from both sides towards the middle, thereby firmly clamping the specimen 17 placed on the specimen lifting and rotating base 3, preventing the specimen 17 from shaking or shifting during rotation and rising, and ensuring the accuracy and stability of the scanning process.

[0027] A specimen detection switch 16 is installed on one outer side of the support of the lead screw guide module 9. The specimen detection switch 16 is used to detect whether the specimen 17 is placed in the designated position. When the specimen 17 is placed on the specimen lifting and rotating base 3 and enters the sensing range of the specimen detection switch 16, the switch will sense the presence of the specimen 17 and transmit this signal to the control system of the entire device. Its function is to provide a starting signal for the operation of the device. Only after the specimen 17 is detected will the device start the drive device 2 according to the preset program, drive the lead screw guide module 9 to work, and raise the lifting plate 4 and the specimen lifting and rotating base 3, thereby performing subsequent clamping, rotation and barcode scanning operations.

[0028] A sensor plate 6 is provided on the side of the lifting plate 4 near the drive device 2, and a sensor switch 7 is provided at the bottom of the bracket of the lead screw guide module 9. The sensor plate 6 and the sensor switch 7 work together to determine whether the lifting plate 4 has descended to the set initial position or other position that needs to be confirmed, thereby controlling whether the drive device 2 stops running or performs other related operations.

[0029] Working principle: Specimen detection switch 16 detects specimen 17, and drive device 2 drives second drive wheel 11 to rotate via first drive wheel 5 and synchronous belt 8. When second drive wheel 11 rotates, the lead screw on lead screw guide module 9 also rotates and rises. As the lead screw on lead screw guide module 9 rotates and rises, lifting plate 4 also rises via lifting guide rod 12 and lifting guide column 13. Simultaneously, specimen lifting and rotating base 3 also rotates and rises synchronously. When specimen lifting and rotating base 3 rises and rotates past specimen lifting and rotating base squeezing block right 14 and specimen lifting and rotating base squeezing block left 15, the two will squeeze the top of specimen lifting and rotating base 3, thereby clamping specimen 17 and causing it to rotate. At this time, specimen 17 rises and rotates, and code reading device 1 begins to read specimen 17 information. After completion, drive device 2 drives in the opposite direction, and after all the mechanisms that just rose return to their original positions, the drive stops, waiting for the next specimen 17. The lifting position is controlled by sensing plate 6 and sensing switch 7. This achieves the effects of simple structure, wide application scenarios, and small space occupation.
