Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, specifically a roll-to-roll labeling machine. Background Technology

[0002] Labeling machines are devices that affix rolls of self-adhesive labels (paper or metal foil) to PCBs, products, or prescribed packaging. As an important component of modern packaging, labeling machines not only improve production efficiency but also ensure the accuracy and consistency of product labels.

[0003] Currently, my country's labeling machines are constantly being innovated and improved in terms of variety and technology, gradually shedding the backward situation of being dominated by manual and semi-automatic labeling machines in the past, and entering a new stage where automated and high-speed labeling equipment dominate the market. With the increasing demands for production efficiency and precision in the manufacturing industry, the application of automated labeling machines has spread to many industries, and has gained widespread market recognition for its high speed, high efficiency, and precision. Current labeling machines can not only handle various label types but also adapt to products of different shapes and sizes, possessing greater flexibility and adaptability to meet the diverse needs of production lines. Especially for high-speed production environments, existing labeling machines mostly use advanced conveyor systems, typically relying on transport lines for product transport. However, when transporting products such as rolls of paper, conductive cloth, or adhesive, if a separate transport line is used for labeling, a winding and storage component needs to be added later. Since these products are all rollable, a roll-to-roll labeling machine can be designed specifically for transporting rollable products. When designing the labeling machine, the layout and assembly position of each assembly mechanism, as well as the accuracy of labeling on rollable products, must also be considered.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0030] Reference Figures 1 to 7 As shown, a roll-to-roll labeling machine includes a lower worktable 1, on which a label peeling unit 2 is provided for transporting paper rolls with labels attached and peeling the labels from the paper rolls. A three-axis robotic arm 3, transporting along the XYZ directions, is also provided on the machine to receive the peeled labels and transport them to be adhered to the corresponding products. A product transport unit 4 is used to sequentially transport multiple labeling points on the rolled product to the labeling positions. The product transport unit 4 includes a transport table 401, with a transport line 402 in the middle for product transport. A rotatable feeding cylinder 403 and receiving cylinder 404 are located on the side of the lower worktable 1 in the transport direction before and after the transport line 402. A roller 405 is provided on the transport table 401 above the transport line 402, and a channel 406 limited to the transport of rolled products is left between the roller 405 and the transport line 402.

[0031] The technical solution is designed with a lower worktable 1 as the support. The lower worktable 1 is equipped with a main label peeling unit 2, a product transport unit 4, and a three-axis robotic arm 3. These three components work together to attach labels to the transported products. This equipment is primarily designed for labeling specific nodes on wound products. Therefore, the product transport unit 4 is designed as follows: The product transport unit 4 includes a transport platform 401. A transport line 402 for product transport is located in the middle of the transport platform 401. A rotatable feeding cylinder 403 and a receiving cylinder 404 are located on the side of the lower worktable 1, in the transport direction before and after the transport line 402. A roller 405 is located on the transport platform 401 above the transport line 402. A channel 406 for transporting wound products is left between the roller 405 and the transport line 402. A corresponding support for the feeding cylinder 403 is located on the side of the lower worktable 1. The side support 407 of the receiving cylinder 404 is equipped with a transport motor 408 that drives the rotation of the discharging cylinder 403 and / or the receiving cylinder 404; the transport table 401 is equipped with an upper support for the two ends of the roller 405, and the roller 405 has a shaft 409 at its center. The shaft 409 extends along both sides of the roller 405 and is assembled with the upper support. The working principle is as follows: the operator places the wound product (such as paper roll, conductive cloth, adhesive, flexible circuit board, etc.) on the discharging cylinder 403, and passes it through the channel 406 on the transport line 402 in sequence, and finally places it in the receiving cylinder 404. The transport motor 408 drives the receiving cylinder 404 to select, thereby driving the winding product to be transported. The channel 406 between the roller 405 and the transport line 402 prevents the winding product from easily tilting up, ensuring that the winding product remains stable during transportation and preventing the labeling part from falling off the labeling position.

[0032] The label peeling assembly 2 is specifically composed of: a support plate 201 assembled on the lower worktable 1, on which a feeding cylinder 202 and a take-up roller 203 are arranged horizontally in sequence. The take-up roller 203 is used to pull out the paper roll on the feeding cylinder 202. At the same time, several guide rollers for guiding the paper roll are provided between the feeding cylinder 202 and the take-up roller 405. The label peeling assembly 2 also includes a drive mechanism to rotate and pull the take-up roller 203. The working principle of the pull motor 207, which consists of the above-mentioned structure, is as follows: the paper roll with the label attached is placed into the feeding cylinder 202, and the paper roll is passed through several guide rollers in sequence, and finally attached to the take-up roller 203. The take-up roller 203 is connected to the pull motor 207 by a chain or the output end of the pull motor 207 is directly connected to the take-up roller 203, so that the take-up roller 203 can be rotated to further drive the paper roll with the label attached to move for transportation. To facilitate the separation of labels from paper rolls during transport, a separation assembly is installed between several guide rollers and near the product transport group 4. This separation assembly includes a paper roll placement plate 204 and a label placement plate 205, with a gap 206 between them. The label placement plate 205 is positioned below the paper roll placement plate 204. When the paper roll with the label attached is transported to the gap 206, the gap is limited to the passage of the paper roll, and the label on the paper roll is affected by the inertia of the paper roll's movement. The paper roll with the label attached moves to the label placement plate 205. First, the loading cylinder 202 and a portion of the guide rollers are positioned above the peeling assembly, while the other portion of the guide rollers and the take-up roller 203 are positioned below the peeling assembly. The paper roll with the label attached flows sequentially from above the peeling assembly through a portion of the guide rollers above the peeling assembly, the gap 206, the other portion of the guide rollers below the peeling assembly, and the take-up roller 203. Due to the inertia of the paper roll's movement, the label on the paper roll moves to the label placement plate 205, awaiting pickup and transport by the three-axis robotic arm 3.

[0033] The design of the three-axis robotic arm 3 includes a vertically oriented assembly base 301 mounted on the lower worktable 1. The assembly base 301 is equipped with an X-axis transmission guide rail, and a motor is mounted at the end of the X-axis transmission guide rail. An X-axis slider assembly that moves along the X-axis direction is mounted on the X-axis transmission guide rail. A Y-axis transmission guide rail is externally connected to the X-axis slider assembly. A motor is mounted at the end of the Y-axis transmission guide rail, and a Y-axis slider assembly that moves along the Y-axis direction is mounted on the Y-axis transmission guide rail. A Z-axis transmission guide rail is externally connected to the Y-axis transmission guide rail, and a motor is mounted at the upper end of the Z-axis transmission guide rail. A Z-axis slider assembly that moves along the Z-axis direction is mounted on the Z-axis slider assembly. A vacuum nozzle 308 that can take in and release air is mounted on the Z-axis slider assembly. A vacuum pump is externally connected to the vacuum nozzle 308 through a conduit. Its working principle is as follows: Motor 1 drives the X-axis slider assembly on the X-axis transmission guide rail to move horizontally along the X-axis, allowing the robotic arm to move back and forth on the worktable in the horizontal direction; Motor 2 drives the Y-axis slider assembly to move vertically along the Y-axis, allowing the robotic arm to adjust in the vertical direction and providing a wider operating range; Motor 3 drives the Z-axis slider assembly to move up and down along the Z-axis, further increasing the robotic arm's positioning flexibility in three-dimensional space and enabling precise up and down adjustment. A vacuum nozzle 308 for taking in and releasing air is installed at the end of the Z-axis slider assembly. When the robotic arm needs to move objects, the vacuum nozzle 308 uses a vacuum pump (not shown in the figure) to perform the adsorption function. The vacuum pump is connected to the vacuum nozzle 308 through a conduit. When adsorbing objects, a negative pressure is formed inside the vacuum nozzle 308, causing the objects to adhere firmly to the nozzle, facilitating the robotic arm's handling or placement of items. After the handling is complete, the vacuum nozzle 308 can release the adsorbed objects through the air release function.

[0034] For the design of the first vision group 101 and the second vision group 501, the first vision group 101 is assembled on the machine base and located between the label peeling group 2 and the product transport group 4. Its scanning direction is upward, used to detect whether the three-axis robotic arm 3 has received the label. The upper end of the lower worktable 1 is provided with a protective plate 102, and the upper end of the protective plate 102 is provided with an upper worktable 5. The second vision group is assembled on the upper worktable 5, and its scanning direction is downward, used to detect whether the corresponding node on the rolled-up product in the product transport group 4 has been transported to the labeling position. The design of the two vision groups can ensure the accuracy of product labeling.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
