Description

Technical Field

[0001] This utility model relates to the field of automated sorting mechanisms, specifically to an OCR dynamic photo recognition and sorting device. Background Technology

[0002] During the production of sample vials, to ensure product traceability and authenticity verification, each vial must be permanently engraved with a character sequence containing key information such as a unique identifier, production date, and batch number using laser marking technology. This sequence strictly follows preset marking rules, forming a traceable data chain.

[0003] Each sample bottle undergoes a laser marking process to ensure that a character sequence containing specific product information is permanently and clearly imprinted on the bottle. This character sequence includes not only key information such as the product's unique identifier, production date, and batch number, but also follows a set of established marking rules to achieve efficient product traceability and end-to-end tracking. A rigorous comparison and analysis is performed between the character sequence extracted by the detection system and the preset marking rules. This comparison process, based on objective data matching logic, ensures accuracy at every step. If the comparison result shows that the character sequence perfectly matches the established marking rules, the system determines that the sample bottle is a product manufactured by this company, thus verifying its authenticity.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-3As shown, the OCR dynamic image recognition and sorting device of this utility model includes: a main support 1, a rotary drive mechanism, a vacuuming mechanism, an OCR dynamic recognition camera 5, and a controller, all fixedly mounted on the main support 1; it also includes a gripper mechanism mounted on the movable end of the rotary drive mechanism, and a multi-axis robot 16 located on one side of the main support; wherein, the multi-axis robot 16 moves the sample bottle 10 to be sorted from the loading station to the sorting station and is clamped by the gripper mechanism, the rotary drive mechanism drives the gripper mechanism and the sample bottle 10 to rotate, and at the same time, the OCR dynamic recognition camera 5 continuously takes pictures and recognizes the rotating sample bottle 10. If the OCR dynamic recognition camera 5 determines that the sample bottle barcode conforms to the set rules, the sample bottle is vacuumed by the vacuuming mechanism at the upper end, and then moved to the qualified product placement area by the multi-axis robot. If it does not conform to the set rules, it is directly transferred to the waste product placement area by the multi-axis robot.

[0032] Specifically, the rotary drive mechanism has a bearing seat 11 fixed to the main support 1, a servo motor 3 connected to the lower end of the bearing seat 11, and a rotary plate 9 connected to the movable end of the servo motor 3; while the gripper mechanism is fixedly installed on the upper end of the rotary plate 9. The servo motor 3 can drive the entire gripper mechanism and the sample bottle 10 to rotate circumferentially, so that the OCR dynamic recognition camera 5 can continuously take pictures and recognize the rotating sample bottle 10.

[0033] The OCR dynamic recognition camera 5 is fixedly mounted on the main support 1 via a horizontal support frame 7 and is located outside the gripper mechanism. A supplementary light 6 is also fixedly mounted on one end of the lens of the OCR dynamic recognition camera 5. The supplementary light 6 provides supplementary lighting to the sample bottle 10, which facilitates the OCR dynamic recognition camera 5 to clearly recognize the barcode on the sample bottle 10 and improves accuracy.

[0034] The gripper mechanism includes a bidirectional double-rod cylinder 2 and a pair of grippers 4. The pair of grippers 4 are respectively connected to the two movable ends of the bidirectional double-rod cylinder 2. The bidirectional double-rod cylinder 2 drives the pair of grippers 4 to move towards the middle at the same time, so as to firmly fix the sample bottle 10 directly below the vacuum needle 12, which facilitates subsequent rotation, photography and identification, and also facilitates the stable insertion of the vacuum needle 12 into the sample bottle 10.

[0035] A receiving plate 8 is provided between a pair of grippers 4, and the receiving plate 8 is provided with a positioning groove that matches the sample bottle 10. When the sample bottle 10 is moved to the vacuum needle by the robot, it is first placed in the positioning groove to initially fix the sample bottle, and then the sample bottle is fixed for a second time by the bidirectional double rod cylinder 2 and the two grippers 4.

[0036] In addition, both grippers 4 have V-shaped grooves at their front ends. When the bidirectional double-rod cylinder 2 and the two grippers 4 perform secondary fixation on the sample bottle, the pair of V-shaped grooves can center and align the sample bottle 10, ensuring that the vacuum needle 12 is aligned with the exact center of the bottle opening. The included angle of the V-shaped grooves matches the curvature of the sample bottle 10, ensuring that the center of the bottle opening coincides with the axis of the vacuum needle 12 during clamping.

[0037] The vacuuming mechanism includes a vacuuming needle 12, a gas distribution block 13, a linear cylinder 15, and a pressure transmitter 14 connected in sequence. The vacuuming needle 12 is located directly above the receiving plate 8. The side of the gas distribution block has a gas pipe interface for connecting to a vacuum pump via a gas pipe. The rear end of the gas distribution block 13 is slidably connected to the main support 1 via the linear cylinder 15. The linear cylinder 15 drives the vacuuming mechanism to be inserted downward into the sample bottle 10 to perform vacuuming on the sample bottle 10.

[0038] The pressure transmitter 14 is connected to the linear cylinder 15 via a signal. The pressure transmitter 14 can convert the physical pressure parameters of gas, liquid and other substances sensed by the pressure measuring element sensor into standard electrical signals, which are then supplied to secondary instruments such as indicators, alarms, recorders and regulators for measurement, indication and process regulation. The pressure transmitter 14 monitors the vacuum pressure in real time and feeds back electrical signals to the linear cylinder 15 to adjust the stroke, thereby realizing automated control.

[0039] In another embodiment, the rotation of the gripper mechanism can also be achieved using different structures. The rotation drive mechanism can be a belt-driven rotation assembly or a pneumatic rotation assembly. The belt-driven rotation assembly includes a drive wheel, a driven wheel, and a synchronous belt. The driven wheel is coaxially connected to the rotating plate 9, and the drive wheel is driven by a servo motor. The pneumatic rotation assembly includes a rotary cylinder and an angle limiter. The turntable of the rotary cylinder is fixedly connected to the rotating plate 9.

[0040] In another embodiment, different structures can be used to clamp the sample bottle. The gripper mechanism can also be an electric push rod gripper or an adaptive gripper. The electric push rod gripper includes a bidirectional lead screw driven by a linear motor, and push blocks with opposite threads at both ends of the lead screw are respectively connected to the gripper 4. The adaptive gripper includes a spring-preloaded wedge slider mechanism, and a floating roller array is provided on the inner side of the gripper 4 to adapt to sample bottles of different diameters.

[0041] The working principle and process of the OCR dynamic photo recognition and sorting device of this utility model are briefly described below.

[0042] First, the multi-axis robot arm 16 moves the sample bottle 10 below the vacuum needle and places it in the positioning groove to initially fix the sample bottle. Then, the bidirectional double-rod cylinder 2 and two grippers 4 fix the sample bottle a second time. Among them, a pair of V-shaped clamping grooves can center and align the sample bottle 10, so that the vacuum needle 12 is aligned with the center of the bottle mouth of the sample bottle 10. Then, the servo motor 3 drives the entire gripper mechanism and the sample bottle 10 to rotate circumferentially. The OCR dynamic recognition camera 5 continuously takes pictures and recognizes the rotating sample bottle 10. The OCR dynamic recognition camera 5 determines whether the sample bottle barcode conforms to the set rules.

[0043] If the OCR dynamic recognition camera 5 determines that the barcode of the sample bottle does not conform to the set rules, it will be directly transferred to the waste placement area by the multi-axis robot arm; if the OCR dynamic recognition camera 5 determines that the barcode of the sample bottle conforms to the set rules, the linear cylinder 15 will move downwards, insert the vacuum needle into the cap of the sample bottle, and finally the vacuum pump connected to the gas distribution block 13 will be used to draw a vacuum, so that the active gas in the sample bottle 10 will be extracted, and finally the multi-axis robot arm will move it to the qualified product placement area.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
