[0002] Equipment that scans labels to achieve error-proof traceability has been applied in many fields. For example, on the assembly line, the model and batch of parts can be verified by scanning the code to avoid mixing or mis-installation. In the supply chain traceability management, cross-border e-commerce can track the logistics path of goods and verify the consistency between customs clearance documents and physical objects. Through error-proof traceability devices, the traceability time of problem products can be shortened from several days to minutes. Consumers scan the code to obtain full life cycle information, thereby promoting purchasing decisions.

[0003] However, when the traceability device for scanning labels in the prior art is used, when scanning flat box-packaged goods, the goods are often placed incorrectly or even flipped due to problems with the front-end conveying equipment itself.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a device for labeling, scanning and error-proofing traceability, comprising a traceability device body, the traceability device body comprising a conveyor belt 1, a placement platform 2, a clamping component 6 and a code scanning component 4, the surface of the conveyor belt 1 is used to support and convey the flattened products, a support frame 36 is built on the side of the conveyor belt 1, a calibration plate 13 is welded on the inner side of the support frame 36, a plurality of calibration points 14 are printed on the surface of the calibration plate 13, one end of the calibration plate 13 is set to an arc structure, and the calibration plate 13 passes through the arc area and the conveyor belt 1 The surfaces are fitted together at one end, a top plate 3 is welded on the top of the support frame 36, the code scanning component 4 is installed on one side of the top plate 3, a transfer mechanism 5 is installed on the top of the support frame 36, a correction component 7 is inserted at the edge of the transfer mechanism 5, a gap is set between the bottom of the correction component 7 and the conveyor belt 1, a clamping component 6 is installed at the end of the transfer mechanism 5, the clamping component 6 is used to clamp and fix the two ends of the product to be scanned, and the end of the support frame 36 is integrally formed with a connecting track 8, and the placement platform 2 is welded to the end of the connecting track 8. The code scanning error-proofing traceability device scans the QR code on the surface label of the product that has moved over the bottom through the code scanning component 4. This application is only used for scanning and error-proofing flattened packaged products.

[0029] When the present invention is used, the product to be scanned is transported toward the bottom of the transfer mechanism 5 by the conveyor belt 1. The transfer mechanism 5 is at the end of the conveyor belt 1 in the initial state. Figure 1 In the state shown, the correction component 7 is always in the upper area of ​​the conveyor belt 1, so the conveyed products can directly enter the lower area of ​​the correction component 7. In this process, if the surface of the conveyed products is stacked, the correction component 7 will push the products stacked on top due to the increase in height, ensuring that only a single product can enter the inner side of the transfer mechanism 5. At this time, the conveyor belt 1 will push the products with the QR code label against the calibration plate 13, and the code scanning component 4 will be used to identify and monitor the number of calibration points 14 on the calibration plate 13, and it can be determined that the product has been fully in place at this time. Obtain the image information of the top surface of the product. If the QR code label is in the top surface area at this time, the scanning and error-proofing traceability process of the product can be completed directly. If the QR code label is at the bottom of the product, the transfer mechanism 5 is started while controlling the scanning component 4 to perform synchronous angle adjustment. When the transfer mechanism 5 flips the product over, the exposed bottom surface area is directly scanned again to complete the scanning process of the label on the bottom surface. In this process, the scanning component 4 can also detect the number of calibration points 14 to determine whether the edge of the current product is parallel to the surface of the flip frame 19.

[0030] In this embodiment, the transfer mechanism 5 includes a flip frame 19, a first motor 11 and a gear 21. Rods are inserted at both ends of the flip frame 19. There are two gears 21, and each gear 21 is key-connected to the surface of the rods at both ends of the flip frame 19. A docking bearing 22 is installed on the outside of one of the gears 21, and a threaded sleeve 23 is welded to the outer ring of the docking bearing 22. An end plate 10 is welded to one side of the placement platform 2. The first motor 11 is screwed to the surface of the end plate 10, and a screw rod 12 is inserted at the output end of the first motor 11. The threaded sleeve 23 is sleeved on the surface of the screw rod 12, and the end of the screw rod 12 is movably connected to the surface of the support frame 36 through a bearing. A rack 9 is welded to the surface of the connecting track 8, and a gap is set between the bottom of the rack 9 and the surface of the connecting track 8, and the gear 21 is used to mesh with the rack 9. The transfer mechanism 5 can be used to transport the goods on the conveyor belt 1 to the other side. During the transportation process, the clamping component 6 clamps the products from the two end areas and then provides rotation. The scanning component 4 can cooperate with the scanning process to identify the two side areas during the transportation process.

[0031] Specifically, when the product is placed, the clamping assembly 6 is started to clamp and fix the front and rear ends of the product. At this time, the first motor 11 can be started, and the screw rod 12 is driven to rotate by the first motor 11. The screw rod 12 cooperates with the threaded sleeve 23 to drive the docking bearing 22 to translate. The docking bearing 22 pulls the gear 21 and the flip frame 19 to translate. In this process, the transfer mechanism 5 first drives the product to be pulled out from the surface of the conveyor belt 1 and the calibration plate 13. As the gear 21 engages with the rack 9 during the movement, the gear 21 and the rack 9 can be used to drive the entire flip mechanism to rotate, thereby achieving the effect of driving the clamped product to flip, and after the gear 21 completely moves over the rack 9, the 180° flipping process of the product can be achieved, and the clamping assembly 6 is controlled to release the clamping force on the product. The product can be placed on the placement platform 2.

[0032] In this embodiment, the clamping assembly 6 includes an electric telescopic rod 34, a movable clamp plate 35 and a fixed clamp plate 20. The fixed clamp plate 20 is integrally formed at one end of the flip frame 19. A vertical plate 30 is welded to the other end of the flip frame 19. A guide plate 31 is integrally formed at one end of the vertical plate 30. A telescopic channel 32 is fixed to the outside of the guide plate 31. The electric telescopic rod 34 is screwed to the inside of the telescopic channel 32. The movable clamp plate 35 is screwed to the end of the electric telescopic rod 34. The bottom of the movable clamp plate 35 is in contact with the surface of the conveyor belt 1 and the calibration plate 13. The outer side of the telescopic channel 32 is sleeved with a sliding wheel 33. The bottom of the sliding wheel 33 is in contact with the surface of the connecting track 8. Specifically, when the product moves to the bottom of the transfer mechanism 5, the electric telescopic rod 34 is started, and the movable clamping plate 35 at the end is controlled by the electric telescopic rod 34 to push the product. The device uses the movable clamping plate 35 to push the product to complete the clamping process of the product. In the subsequent flipping process of the transfer mechanism 5, the product is always driven to rotate from both ends without blocking the two sides of the flat product packaging.

[0033] In this embodiment, the correction assembly 7 includes a sliding frame 27, a second motor 28 and a push belt 29. A support plate 24 is welded on the top of the flip frame 19. A slide groove 25 is provided on the inner side of the support plate 24. A locking hole 26 is provided on the top of the support plate 24. One end of the sliding frame 27 is embedded in the slide groove 25. A second motor 28 is welded at the end of one sliding frame 27. A push belt 29 is sleeved on the output shaft of the second motor 28. A rubber convex strip 37 is attached to the top of the push belt 29. The end of the other sliding frame 27 is connected to the end of the push belt 29 by a shaft. The gap between the bottom of the push belt 29 and the surface of the conveyor belt 1 is greater than the thickness of the product to be scanned. A gap is set between the transfer mechanism 5 and the conveyor belt 1, and products with the same thickness as the gap can be sorted. When the conveyed products are stacked, the stacked products can be separated, thereby ensuring that the products can be stably identified and scanned, reducing the probability of omission.

[0034] Specifically, when the conveyed products are stacked, when the stacked products are moved along the conveyor belt 1 toward the bottom of the transfer mechanism 5, the top product will be directly blocked by the top push belt 29 until the top product is pushed out toward the rear end, ensuring that only a single product at the bottom is moved to the subsequent scanning and clamping area.

[0035] In this embodiment, the code scanning component 4 includes an extension rod 15, a support column 16 and a code scanning module 17. The extension rod 15 is welded to the side of the top plate 3. The end of the extension rod 15 is inserted with a support column 16, and the code scanning module 17 is fixed on the surface of the support column 16. An angle control module 18 is provided at one end of the support column 16. The angle control module 18 is used to drive the code scanning module 17 to switch the code scanning recognition inclination angle. The code scanning module 17 is used to scan and recognize the surface of the calibration plate 13 and the transfer mechanism 5 area in the flip state. The product is transported toward the surface of the calibration plate 13 by the conveyor belt 1 at the front end. With the help of the code scanning component 4 and the two rows of calibration points 14 for positioning on the calibration plate 13, the flattened packaged goods with offset placement angles can be identified, and the correction component 7 can be used to perform correction processing after identifying the offset of the product.

[0036] In this embodiment, a rectangular flat packaging product is provided for identification using a code scanning component 4. Specifically, when a single product is transferred to the calibration plate 13, if one side of the product is completely in contact with the inner side of the flip frame 19, the number and position of the two rows of calibration points 14 being blocked are completely consistent. At this time, the code scanning module 17 can identify the exposed position and number of the two rows of calibration points 14 to determine that the product has completed the placement process. If it is identified that the blocked position and number of the two rows of calibration points 14 are different, it means that the current product is in an offset state, so the second electric The machine 28 controls the top rubber convex strip 37 to rotate downward by pushing the belt 29, so that the offset product can be pushed longitudinally, and with the support of the conveyor belt 1, one side of the rectangular product can be completely fitted with the flip frame 19 to achieve a standard placement angle. Then, the surface of the placed product can be labeled and scanned for identification. Among them, the scanning module 17, the angle control module 18 and the collection and identification process of the calibration point 14 are all existing mature technologies and do not belong to the protection scope of the present invention. Therefore, its internal structure and operating principle are not described here.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
