Description

Device for laser printing information and barcodes on the outer wall of blood collection tubes and its usage method Technical Field

[0001] This invention belongs to the field of mechanical technology, specifically a device and method for laser printing information and barcodes on the outer wall of a blood collection tube. Background Technology

[0002] Blood collection is a common procedure in medical settings and must be performed in a specific order to ensure safety and accuracy. Before collecting blood, medical staff should verify the doctor's orders and affix the appropriate label to the test tube to ensure that the collected specimen matches the patient's information.

[0003] Existing technologies typically use label printers to print paper labels, which are then manually affixed to test tubes. This process is inefficient and slow, resulting in long queues during peak hours and extended waiting times for patients. Furthermore, manual affixing can easily lead to skewed angles, making it difficult for subsequent automated detection equipment to scan and identify the labels. The cost of consumables for a large number of paper labels is also a significant expense. Therefore, there is a need for a device that laser-prints information and barcodes on the outer wall of blood collection tubes. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a device and method for laser printing information and barcodes on the outer wall of blood collection tubes, which enables laser printing on test tubes and improves label marking efficiency.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: a device for laser printing information and barcodes on the outer wall of a blood collection tube, comprising a base and a test tube, wherein the test tube has a pre-made engraving layer, and the base is provided with a test tube holder and a laser engraving machine;

[0006] The test tube holder includes an electric lead screw, a mounting platform slidably connected to the electric lead screw, a cylinder on the mounting platform, a mounting plate fixedly connected to the output shaft of the cylinder, a rotating rod rotatably connected to the bottom of the mounting plate, a driver for driving the rotating rod to rotate, and a mechanical claw for gripping the test tubes fixedly connected to the bottom of the rotating rod.

[0007] An electric hatch is provided on the base, and the base contains a material delivery compartment for storing test tubes of various colors and a controller.

[0008] The above solution achieves the following beneficial effects: Users fill unengraved test tubes into the material delivery compartment. At the start of operation, the electric door opens, the cylinder contracts, and the mechanical gripper descends into the material delivery compartment to pick up the material. Subsequently, the cylinder extends, raising the mechanical gripper to remove the test tube and then closing the door. This prevents contaminants and dust from entering the material delivery compartment during engraving. The mechanical gripper is moved by a lead screw and rotated by a driver, facing the laser engraving machine. The laser engraving machine then engraves information on the engraving layer of the test tube. This engraving layer is applied before the test tube leaves the factory and surrounds the tube, eliminating the need for position detection like with paper labels. After engraving, the mechanical gripper is rotated and moved out by the lead screw. Medical personnel can then retrieve the test tube for blood collection.

[0009] Compared with existing technologies, the automated control of printing information barcodes on test tubes reduces manual labor intensity and improves work efficiency; the laser engraving machine eliminates the need for pasting, reducing work steps and eliminating the skewing caused by manual pasting.

[0010] Furthermore, the driver includes a motor, a first gear is fixedly connected to the output shaft of the motor, and a second gear is coaxially mounted on the rotating rod via a sliding key. The second gear is rotatably connected to the mounting platform, and the first gear and the second gear are driven by a belt.

[0011] Beneficial effects: The motor can drive the first gear to rotate, and then the rotating rod will rotate through the belt, thereby changing the orientation of the mechanical claw.

[0012] Furthermore, a photoelectric laser switch is installed on the base, and the photoelectric laser switch is located on both sides of the electric hatch.

[0013] Beneficial effects: The photoelectric laser switch can be triggered by the mechanical gripper. After engraving is completed, the electric screw drives the mechanical gripper to move, which in turn triggers the photoelectric laser switch, automatically opening the electric hatch.

[0014] Furthermore, an identity verification card reader is installed on the base.

[0015] Beneficial effects: Card readers are used to authenticate and verify the identity of users.

[0016] Furthermore, a test tube collection box is provided on the base.

[0017] Beneficial effects: After the engraving is completed, the robotic gripper will place the engraved test tube into the test tube collection box and begin engraving the next test tube, without waiting for the user to take it off the robotic gripper, thus improving processing efficiency.

[0018] Furthermore, a test tube conveying assembly is provided on the base, which extends to the next workstation.

[0019] Beneficial effects: After the engraving is completed, the robotic gripper can choose to place the test tube on the conveyor assembly, so that the test tube can flow directly to the next workstation, which facilitates the coordination between workstations.

[0020] Furthermore, the laser engraving machine is a three-axis laser engraving machine, capable of printing a single 120° fan-shaped area, and has preset automatic zoom and automatic compensation programs.

[0021] Beneficial effects: The three-axis laser engraving machine can solve the problem of image distortion. It adopts a single 120° fan-shaped range printing to quickly complete information engraving. The automatic zoom and automatic compensation functions enable it to adapt to various pipe diameters and reduce the amount of manual adjustment work.

[0022] Furthermore, the method of using the device for laser-printing information and barcodes on the outer wall of the blood collection tube includes the following steps:

[0023] Step 1: Apply an engraving layer to the test tube, making sure the engraving layer surrounds the test tube. Then, place the engraved test tube into the material delivery compartment to prepare the materials.

[0024] Step two: Swipe the ID card to start the process. The controller will read the information to be printed, generate an information barcode, and the robotic gripper will complete the test tube removal and engraving work.

[0025] Step three: After the engraving is completed, the robotic gripper places the test tubes into the test tube collection box. Users can engrave test tubes in batches and then take them out of the test tube collection box for subsequent work.

[0026] Beneficial effects: The engraved layer surrounds the test tube, eliminating the need for circumferential label positioning. The test tube collection box can store the engraved test tubes, enabling batch engraving and improving work efficiency.

[0027] Furthermore, in step three, blood collection and carving are divided into two workstations. After carving is completed, the robotic gripper transports the test tube to the workstation for blood collection via the test tube transfer assembly.

[0028] Beneficial effects: It separates the engraving and blood collection processes. The workstation handles the storage and use of test tubes, while the engraving station only needs to continuously input patient information for engraving. This workstation coordination improves work efficiency. In multi-station scenarios, after calculating work efficiency, one device can be used to match multiple workstations, using concealed conveyor belts to deliver supplies to each workstation, thus reducing equipment costs.
