Description

Technical Field

[0001] The present invention relates to the technical field of commodity cigarette processing, and in particular to a basic large-scale tobacco OCR recognition device and a recognition method. Background Art

[0002] Commodity cigarette processing generally refers to the processing of various tobacco products made from commodity cigarettes as raw materials. Tobacco products include cigarettes, cigars, silk tobacco, snuff, chewing tobacco, etc. Among them, cigarettes have the largest output, consuming more than 85% of the total tobacco leaves. Therefore, the commodity cigarette industry mainly refers to the cigarette industry. Due to the wide consumption, large volume and high taxation of cigarettes, the cigarette industry occupies a vital position in the economies of various countries. In the commodity cigarette processing process, commodity cigarette OCR technology uses optical character recognition algorithms to recognize text information related to commodity cigarettes. Through OCR technology, the text on paper or images can be converted into a computer-editable text format. In the commodity cigarette production process, OCR recognition is performed on raw material warehouse receipts and process record sheets in the production process. The purchase receipt of commodity cigarettes records the origin, grade, quantity and other information of the commodity cigarettes. After OCR recognition, it can be directly entered into the company's production management system, improving the efficiency and accuracy of data entry.

[0003] In the existing technical field, in the process of commercial cigarette processing, external commercial tobacco enters the production line from the outside in the form of bundled packaging, and workers are required to enter information before unpacking. The current information entry method uses manual handheld devices, which require searching for label positions one by one, and also requires the commercial cigarettes to be flipped over, causing fatigue to workers during the work process, further affecting work efficiency and quality. In addition, manual operation has certain subjectivity and fatigue, which may lead to missing labels or damage to the commercial cigarette bundles during the flipping process, thereby affecting the accuracy of OCR input.

[0067] Here’s how it works:

[0068] Step 1: The staff remotely controls the main controller 2 to start the handling robot 3. The internal preset program of the handling robot 3 transports the external cigarette and tobacco leaf bundle to the lower right position inside the first conveyor belt 4. The staff controls the main controller 2 to start. The internal preset program of the main controller 2 controls the truss handling robot 1, the first conveyor belt 4, the second conveyor belt 51, the first electric telescopic rod 63, the first motor 69, the second electric telescopic rod 614, the recognition camera 613 and the first rotation module 64 to start. The truss handling robot 1 clamps the cigarette bundle on the top of the handling robot 3 and transports it to the surface of the first conveyor belt 4. The first conveyor belt 4 transports the cigarette bundle on its top from back to front to the surface of the second conveyor belt 51. The cigarette bundle on the surface of the second conveyor belt 51 moves to the bottom of the identification component 6. The first electric telescopic rod 63 extends to drive the plug-in telescopic frame 62 to move downward. The inserted telescopic frame 62 is made to lower the identification camera 613 to a specified height position under the cooperation of the first rotating module 64, the height adjustment frame 65 and the arc-shaped slot plate 66 below. The first motor 69 drives the internal gear of the ring gear set 67 to move along the arc-shaped rack, and then drives the mounting plate 68 to move in an arc shape under the cooperation of the first motor 69. The second electric telescopic rod 614 extends and shortens to drive the mounting seat 612 to move inward or outward to adjust the distance between the identification camera 613 and the outer packaging of the cigarette bundle. The identification camera 613 identifies the label affixed to the outer packaging of the cigarette bundle and determines the location of the label. The first rotating module 64 drives the height adjustment frame 65 to rotate clockwise or counterclockwise, and then adjusts the direction of the arc-shaped slot plate 66 to achieve all-round identification of the identification camera 613 on the outside of the cigarette bundle packaging.

[0069] Step 2: When the cigarette bundle needs to be rotated so that the label is in the upper position, the second conveyor belt 51 drives the cigarette bundle to move to the position below the position adjustment component 7, and the preset program inside the main controller 2 controls the second motor 75, the third motor 79, the third electric telescopic rod 715, the second rotation module 717, the second rotation module 710, the fourth electric telescopic rod 721, the electric lifting platform 722, the fifth electric telescopic rod 726, the dual-axis mobile platform 53 and the image acquisition camera 54 to start, and the second motor 75 drives the pulley on one side of the belt assembly 74 to rotate, so that the belt inside the belt assembly 74 drives the moving seat 73 to move to the specified position to the left or right along the outside of the track 72, so that the first mounting bracket 76 below is aligned with the cigarette bundle, and the third motor 79 drives the third electric telescopic rod 715 to move to the specified position to align with the cigarette bundle. The machine 79 drives the screw in the screw assembly 78 to rotate, so that the screw nut inside the screw assembly 78 drives the second rotating module 710. The second rotating module 710 is lifted and lowered to a specified height position under the limiting action of the second slider assembly 77. The third electric telescopic rods 715 on the left and right sides extend to drive the rotating rods 714 on the corresponding positions to rotate inward in the inner cavity of the installation groove 712. Under the limiting action of the limiting rods 713 on both sides, the rotating rods 714 drive the connecting seats 716 to move inward, and the connecting seats 716 on both sides drive the clamping arms 718 to move inward to clamp and fix the cigarette bundle under the cooperation of the second rotating modules 717. The second rotating modules 717 on both sides control the clamping arms 718 to rotate clockwise or counterclockwise as needed, so that the clamping arms 718 on both sides can be fixed. After the holding arm 718 drives the cigarette bundle to rotate upward or downward, its label position is at the top. The second rotating module 710 drives the mounting truss 711 to rotate clockwise or counterclockwise according to actual needs. The second rotating module 710 drives the cigarette bundle to rotate clockwise or counterclockwise to the left or right with the cooperation of the clamping arms 718 on both sides, so that its label position is at the top. After the flip is completed, the fourth electric telescopic rods 721 on both sides extend and drive the telescopic rods 720 to extend to the specified length position in the inner cavity of the slot frame 719, so that the electric lifting platform 722 is located just above the cigarette bundle. The electric lifting platform 722 lifts the second mounting frame 723 to the specified height position so that the clamping claws 725 are located on the left and right sides of the cigarette bundle. The fifth electric telescopic rod 7 26 shortens and drives the clamping claw 725 on one side to move inward, and makes the clamping claw 725 on this side drive the rack rod 728 at the corresponding position to move inward under the limiting action of the slot seat 727. Under the cooperation of the transmission gear 729, the slot seat 727 on the other side and the rack rod 728, the clamping claw 725 on the other side moves inward synchronously. The clamping claws 725 on both sides clamp and fix the left and right sides of the flipped cigarette bundle. The third electric telescopic rods 715 on both sides extend to drive the rotating rod 714 to drive the connecting seat 716 to rotate outward, and the clamping arms 718 on both sides release the clamping fixation of the cigarette bundle. The fourth electric telescopic rod 721 extends to drive the electric lifting platform 722 to move backward, and with the cooperation of the clamping claws 725 on both sides, the cigarette bundle is moved a certain distance backward.The second motor 75 drives the belt assembly 74 to rotate, causing the movable base 73 to move the first mounting frame 76 to the left or right to the outside of the top of the second conveyor belt 51. The electric lifting platform 722, in cooperation with the left and right clamping claws 725, lowers the cigarette bundle to the surface of the second conveyor belt 51. The fifth electric telescopic rod 726 extends and drives the clamping claws 725 on both sides to move outward to release the cigarette bundle. The second conveyor belt 51 drives the cigarette bundle to the inside of the fixed frame 52. The dual-axis movable platform 53 drives the image acquisition camera 54 to the top of the label. The image acquisition camera 54 captures the label and generates image data. The image acquisition camera 54 sends the image data to the text and image processing device through the main controller 2 for processing and storage.

The third motor (79) drives the second rotating module (710) to move up and down to a specified height position through the screw assembly (78). The third electric telescopic rods (715) on the left and right sides drive the rotating rods (714) at the corresponding positions to rotate inward. Under the limiting action of the limiting rods (713) on both sides, the rotating rods (714) drive the connecting seat (716) to drive the clamping in cooperation with the second rotating module (717). The arm (718) moves inward to clamp and fix the cigarette bundle, and the second rotating modules (717) on both sides control the clamping arms (718) to rotate clockwise or counterclockwise as needed, so that the clamping arms (718) on both sides drive the cigarette bundle to rotate upward or downward so that the label is located at the top. The second rotating module (710) drives the mounting truss (711) to rotate clockwise or counterclockwise as needed. The second rotating module (710) drives the cigarette bundle to rotate clockwise or counterclockwise to the left or right in cooperation with the clamping arms (718) on both sides so that the label is located at the top. Step 6: After the second rotating module (710) drives the clamping arm (718) to flip the cigarette bundle to the left and right directions, the fourth electric telescopic rods (721) on both sides drive the telescopic rods (720) to extend and retract to the specified length position in the inner cavity of the slot frame (719), so that the electric lifting platform (722) is located directly above the cigarette bundle. The electric lifting platform (722) lifts the second mounting frame (723) to the specified height position. The fifth electric telescopic rod (726) shortens and drives the clamping claw (725) on one side to move inward. The clamping claw (725) on the other side moves inward synchronously with the cooperation of the transmission gear (729) and the slot seat (727) and the rack rod (728). The clamping claws (725) on both sides clamp and fix the flipped cigarette bundle on the left and right sides. The third electric telescopic rods on both sides The telescopic rod (715) is extended to drive the rotating rod (714) to drive the connecting seat (716) to rotate outward, and the clamping arms (718) on both sides release the clamping fixation of the cigarette bundle. The fourth electric telescopic rod (721) is extended again to drive the electric lifting platform (722) to move backward, and the cigarette bundle is moved to the rear side with the cooperation of the clamping claws (725) on both sides. The second motor (75) drives the belt assembly (74) to rotate so that the movable seat (73) drives the first mounting frame (76) to move to the left or right to the outer position of the top of the second conveyor belt (51). The electric lifting platform (722) lowers the cigarette bundle to the surface position of the second conveyor belt (51) with the cooperation of the clamping claws (725) on the left and right sides. The fifth electric telescopic rod (726) is extended to drive the clamping claws (725) on both sides to move outward to release the fixation of the cigarette bundle. Step 7: The second conveyor belt (51) drives the cigarette bundle to move to the inner side of the fixed frame (52), and the dual-axis mobile platform (53) drives the image acquisition camera (54) to move to the top of the label. The image acquisition camera (54) shoots the label to generate image data. The image acquisition camera (54) sends the image data to the text image processing device through the main controller (2) for processing and storage.
