Description

Technical Field

[0001] This utility model relates to the field of barcode label detection technology, specifically to a device for collecting and rejecting barcodes on packaged products. Background Technology

[0002] In the production and logistics of packaged products, barcodes are widely used as information carriers for product traceability, inventory management, and inbound / outbound records. However, barcode anomalies (such as missing, duplicate, or incorrectly affixed barcodes) can directly lead to disordered logistics information or product recall risks. Although existing automated equipment can perform barcode scanning and rejection, it often uses a single rejection method (such as cylinder pushing), which can easily cause physical damage to the packaging surface and has insufficient recognition capability for labels made of complex materials (such as laminated labels and reflective metallic labels). In addition, traditional equipment lacks a label pre-processing mechanism, and direct removal can easily lead to label residue or packaging damage in situations where the label is highly adhesive or the ambient humidity is high. Therefore, those skilled in the art propose a solution to address this issue by developing a barcode collection and rejection device for packaged products. Utility Model Content

[0026] To provide a clearer explanation and description of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0027] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of each embodiment. Specific details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures. The disclosures of various publications, patents, and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solutions of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0028] Example 1: The packaging product barcode collection and rejection device of this example includes a barcode scanner 1 and a barcode label rejection mechanism 2. The barcode scanner 1 has a scanning head 13 fixed to the top of its handle 11, a trigger 12 on its front side, and control buttons on its rear side corresponding to the start and stop of the servo cylinder 222 and the micro water pump 233, respectively. The barcode label rejection mechanism 2 is fixedly connected to the bottom front side of the scanning head 13 via the top end face of an L-shaped fixing plate 21. In the reciprocating scraper assembly 22, the servo cylinder 222 is fixed to the bottom rear side of the L-shaped fixing plate 21 via a hanger 221. Its front end is connected to a support plate 224 via a connecting plate 228 and a support rod 223. The top of the support plate 224 is fixed to the bottom front side of the L-shaped fixing plate 21, and a piston cylinder 227 is embedded inside. The piston 226 slides back and forth within the piston cylinder 227, and its front end is connected to a scraper 225. The water tank 231 of the label softening component 23 is fixed to the bottom left and right sides of the L-shaped fixing plate 21. It contains an alcohol solution and is equipped with a liquid level sensor. A micro water pump 233 is connected to the rear side via a suction pipe 232. The outlet of the micro water pump 233 is connected to a nozzle 235 via a gooseneck tube 234. The left nozzle 235 is located below the scraper 225, and the right nozzle 235 is located above it, with the spray direction aimed at the barcode label. During operation, the user holds the handle 11 and pulls the trigger 12 to activate the scanner 13 to read the barcode. If the label needs to be removed, the corresponding button is pressed to start the micro water pump 233. The alcohol solution wets the label and the surface of the scraper 225 through the nozzle 235. Then, the servo cylinder 222 is activated, and the piston 226 drives the scraper 225 forward, using the low resistance characteristic after wetting to remove the label.

[0029] Example 2: This example optimizes the nozzle 235 angle adjustment function based on Example 1. The gooseneck tube 234 of the label softening component 23 is replaced with a 360° rotatable universal hose, and a detachable nozzle, such as a fan-shaped or conical nozzle, is added to the front end of the nozzle 235. The water tank 231 is equipped with both acetone and alcohol solutions. The liquid extraction path of the micro water pump 233 can be switched via a button, such as by setting a solenoid valve. During operation, the user can select the solvent according to the label material, such as alcohol for plastic labels and acetone for paper labels, and adjust the nozzle 235 angle through the universal hose to ensure the solution is accurately sprayed onto the label edge. During removal, the servo cylinder 222 drives the scraper 225 at a preset pressure. The label is removed by adjusting the cylinder stroke, reducing the risk of residue.

[0030] Example 3: This example is for mass-produced packaging products and adopts a dual-station structure. Two sets of barcode label rejection mechanisms 2 are symmetrically arranged on both sides of the handle 11 of the barcode scanner 1, and each mechanism is independently controlled. The L-shaped fixing plate 21 is connected to the bottom of the scanning head 13 via a rotating shaft and can be manually rotated 180° to switch stations. The servo cylinder 222 of the reciprocating scraper assembly 22 is replaced with a double-piston cylinder, with a scraper 225 and a piston cylinder 227 connected to each side. The water tank 231 of the label softening assembly 23 is connected to the left and right micro water pumps 233 via a three-way valve to achieve solvent sharing. During operation, the user places the product in the left and right stations in sequence, scans the barcode on the left first, and starts the left micro water pump 233 and servo cylinder 222 to complete the rejection; rotate the L-shaped fixing plate 21 to the right station and repeat the operation.

[0031] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0032] The operator holds the handle 11 of the barcode scanner 1, aligns the scanning head 13 with the barcode area on the surface of the packaged product, and pulls the trigger 12 to initiate the scanning action. The scanning head 13 completes the barcode data acquisition and transmits it to the background system for verification or recording. If the system determines that the barcode label needs to be removed, the operator starts the miniature water pump 233 of the label softening component 23 through the corresponding control button on the back of the handle 11. The miniature water pump 233 draws solvent, such as alcohol or acetone solution, from the water tank 231 through the liquid extraction tube 232. The solvent is delivered to the nozzle 235 through the gooseneck tube 234. The left nozzle 235 sprays the solvent onto the bottom area of ​​the barcode label to soften the adhesive layer between the label and the packaging surface. At the same time, the right nozzle 235 sprays the solvent onto the upper and lower surfaces of the scraper 225 to reduce the frictional resistance during the scraping process.

[0033] After the solvent spraying is completed, the operator presses another control button to start the servo cylinder 222 of the reciprocating scraper assembly 22. The telescopic end of the servo cylinder 222 pushes the piston 226 to slide forward along the piston cylinder 227, driving the scraper 225 to cut into the label edge. Utilizing the low adhesion properties of the softened solvent, the label is removed from the packaging surface. During the removal process, the scraper 225 maintains a stable movement trajectory through the rigid connection structure between the support plate 224 and the support rod 223. If it is an automated integrated device, after the barcode scanner 1 and the industrial camera work together to complete the label positioning, the PLC controller will adjust the settings according to the preset parameters. The coordinate system automatically adjusts the position of the L-shaped fixing plate 21 and controls the scraper 225 to complete the scraping action with constant pressure and speed through the closed-loop servo cylinder 222. At the same time, the solenoid valve of the label softening component 23 dynamically adjusts the spray flow according to the label material, and the waste label automatically falls into the collection tank through the scraping path. After a single operation is completed, the micro water pump 233 stops running, the servo cylinder 222 drives the scraper 225 to reset, and the operator can continue to perform the barcode collection or rejection process for the next product. The liquid level sensor of the water tank 231 monitors the solvent balance in real time, and triggers the liquid inlet valve to automatically replenish the liquid when it is below the threshold.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
