Detailed Implementation

[0027] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0028] like Figures 1-6As shown, this utility model provides a barcode scanning device for blood collection tubes, used to automatically scan the barcodes on the blood collection tubes. Each blood collection tube involved in this utility model has a sealing cap on its top, and its bottom surface is arc-shaped. The barcode scanning device of this application includes a mounting plate 100, on which a slide rail 101 is provided along the vertical direction. A slider 102 is slidably connected to the slide rail 101. A lifting drive motor 200 is fixedly connected to the mounting plate 100, and a support plate 300 is connected to its driving end. One end of the support plate 300 is fixed to the slider 102, and the other end faces the blood collection tube 001. The lifting drive motor 200 drives the support plate 300 to move up and down along the slide rail 101.

[0029] The lifting drive motor 200 in this utility model is a lead screw stepper motor.

[0030] Preferably, the top of the slide rail 101 is provided with a limiting plate 103 to limit the maximum height of the support plate 300.

[0031] A connecting sheet metal 104 is connected below the mounting plate 100. A barcode scanning module 800 is connected to the connecting sheet metal 104 for scanning the barcode on the blood collection tube 001. When the barcode on the blood collection tube 001 is rotated to face the barcode scanning module 800, it can scan the blood collection tube 001. The specific installation position of the barcode scanning module 800 can be adaptively adjusted by those skilled in the art according to the overall structural layout of the entire device, so as to be able to quickly align with the blood collection tube 001.

[0032] A support base 400 is provided on the top part of the support plate 300 facing the blood collection tube 001. The support base 400 includes a rectangular support body and a support plate part extending from one side of the support body toward the blood collection tube 001. A support platform through hole 401 is provided on the support plate part. The photoelectric limit sensor 801 is fixed to the support body, and its sensing part 8011 is located above the support platform through hole 401. It is used to detect whether the cylindrical pin 600 has risen into place.

[0033] The fixed end of the rotary drive motor 500 is connected to the support plate and is located on the side of the support platform through hole 401 near the blood collection tube 001. The drive end of the rotary drive motor 500 passes through the support plate and is connected to a drive gear 501. The rotary drive motor 500 drives the drive gear 501 to rotate around the central axis in the vertical direction of its drive end.

[0034] A cylindrical sliding groove 301 is provided on the side of the support plate 300 facing the blood collection tube 001. The central axis of the sliding groove 301 is coaxially arranged with the central axis of the support platform through hole 401. A cylindrical receiving chamber 3011 is provided at the lower end of the sliding groove 301, and the diameter of the receiving chamber 3011 is larger than that of the sliding groove 301. A cylindrical pin 600 passes through the sliding groove 301 and the receiving chamber 3011 and is slidably connected to the sliding groove 301 and the receiving chamber 3011. A driven gear 502 is sleeved on the upper end of the cylindrical pin 600 and meshes with the driving gear 501. A rotating disk 700 is connected to the bottom end of the cylindrical pin 600 located on the bottom surface of the receiving chamber 3011. An elastic element 701 is placed in the receiving chamber 3011, with one end connected to the inner wall of the top end of the receiving chamber 3011 and the other end fixed to the rotating disk 700. When the elastic element 701 is in a non-compressed state, it is the initial state of the device of this application, and the top end of the cylindrical pin 600 is located below the through hole 401 of the support platform.

[0035] The elastic element 701 in this utility model is a spring.

[0036] Preferably, a silicone pad 702 is attached to the bottom surface of the rotating disk 700 facing the blood collection tube 001. When the pad 702 comes into contact with the top surface of the blood collection tube 001, it is used to increase the friction between the pad 702 and the top surface of the blood collection tube 001.

[0037] Furthermore, the device of this application also includes a test tube rack 900, on which a plurality of insertion holes 901 are arranged at intervals along its length. The outer peripheral surface of each insertion hole 901 is an open arc shape, and the size of the opening is suitable for the size of the barcode. The side of the opening of each insertion hole 901 is a barcode scanning opening 902, and each blood collection tube 001 is placed in the insertion hole 901.

[0038] The test tube rack 900 is placed on a linear motion module (not shown) and is located below the rotating disk 700. The barcode scanning opening 902 of each insertion hole 901 is positioned towards the barcode scanning module 800. The linear motion module drives the test tube rack 900 to move along its length, so that each blood collection tube 001 on the test tube rack 900 passes through the barcode scanning module 800 in sequence. Preferably, a positioning sensor (not shown) is also provided on the side of the support plate 300 facing the blood collection tube 001 to detect whether each blood collection tube 001 is located directly below the silicone pad 702.

[0039] The operation process of this utility model is as follows:

[0040] Barcode-affixed blood collection tubes 001 are sequentially inserted into each insertion hole 901. They move towards the barcode scanning module 800 along with the linear motion module. When a blood collection tube 001 moves directly below the silicone pad 702, the positioning sensor sends an indication signal. The lifting drive motor 200 lowers the support plate 300, and the components connected to the support plate 300 also descend synchronously. When the silicone pad 702 abuts against the top surface of the blood collection tube 001, the lifting drive motor 200 further lowers the rotating disk 700 and the silicone pad 702. This causes the cylindrical pin 600, which connects to the rotating disk 700, to move upwards along the sliding through groove 301 until the top surface of the cylindrical pin 600 passes through the support platform through hole 401 and touches the sensing part 8011 of the photoelectric limit sensor 801, triggering a cylindrical pin. When pin 600 reaches its designated position, the rotary drive motor 500 drives the drive gear 501 to rotate. The drive gear 501 simultaneously drives the driven gear 502 to rotate. The driven gear 502 drives the cylindrical pin 600, the rotating disk 700 at the bottom of the cylindrical pin 600, and the silicone pad 702 to rotate synchronously. The blood collection tube 001, which abuts against the silicone pad 702, also rotates synchronously. At the same time, the elastic element 701 is compressed. When the barcode on the blood collection tube 001 rotates to the scanning opening 902, the scanning module 800 scans and records the information on the barcode, completing the barcode scanning work on the blood collection tube 001. The lifting drive motor 200 drives the rotating disk 700 and the silicone pad 702 to rise, and the cylindrical pin 600 resets under the action of elastic rebound force. This process is repeated.

[0041] The device of this application uses the top of the blood collection tube to drive its rotation, so it is suitable for blood collection tubes of different heights and diameters.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
