Technical Field
[0001] This utility model relates to the field of labeling machine technology, specifically a visual 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] Labeling machines are widely used in various industries, such as backlight panel lamination in electronics, applying QR code labels, adhesive tape, adhesive strips, conductive films, double-sided adhesive, high-temperature adhesive, and display modules.
[0004] When designing a visual labeling machine, the main processes include label feeding and product labeling. Therefore, the following points need to be considered during the design process: (1) When designing a labeling machine, the space utilization rate should be fully considered, and the layout and assembly position of each assembly mechanism should be reasonably planned; (2) It should be ensured that the detection label is adhered to the corresponding product.

[0011] Furthermore, the upper end of the support guide rod is provided with a fixing block that is fixed to the outer shell of the transport platform. The fixing block is an L-shaped profile plate, and the upper surface of the adjustment guide rod is provided with a locking nut that is threadedly connected to it.
[0012] Furthermore, the three-axis robotic arm includes a vertically oriented assembly base, on which is provided an X-axis drive rail. A motor is located at the end of the X-axis drive rail. An X-axis slider assembly that moves along the X-axis direction is located on the X-axis drive rail. A Y-axis drive rail is externally connected to the X-axis slider assembly. A motor is located at the end of the Y-axis drive rail. A Y-axis slider assembly that moves along the Y-axis direction is located on the Y-axis drive rail.

A Z-axis slider assembly that moves along the Z-axis direction is located on the Z-axis drive rail. A vacuum nozzle for taking in and releasing air is located on the Z-axis slider assembly. A vacuum pump is externally connected to the vacuum nozzle via a conduit.
[0013] Furthermore, the label peeling assembly also includes a pull motor that drives the receiving roller to rotate and pull; the product transport assembly also includes a transport motor that drives the products placed on it to transport.
[0014] Furthermore, the upper workbench is equipped with a control panel, which includes a display screen and several control buttons.

[0028] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:
[0029] refer to Figures 1 to 6A vision labeling machine includes a lower worktable 1, on which a label peeling group 2 is provided for transporting paper rolls with labels attached and peeling the labels from the paper rolls; a product transport group 3 is provided for transporting products to the labeling position for labeling; wherein the transport direction of the label peeling group 2 and the transport direction of the product transport group 3 are perpendicular to each other; a three-axis robotic arm 4 is also provided on the machine, transporting along the XYZ direction for receiving the peeled labels and transporting them to be adhered to the corresponding products; at the same time, a first vision group 5 is provided on the machine between the label peeling group 2 and the product transport group 3, with the scanning direction of the first vision group 5 being upward, for detecting whether the three-axis robotic arm 4 has received the labels; a protective enclosure 6 is provided on the upper end of the lower worktable 1, and an upper worktable 7 is provided on the upper end of the protective enclosure 6, with a second vision group 8 on the upper worktable 7, with the scanning direction of the second vision group 8 being downward, for detecting whether the products on the product transport group 3 have been transported to the labeling position.
[0030] The technical solution is mainly designed with a lower worktable 1 as the carrier. The lower worktable 1 is equipped with a main label peeling unit 2, a product transport unit 3, a three-axis robotic arm 4, a first vision unit 5, and a second vision unit 8. The purpose is to: automatically separate the labels from the paper rolls during transport; allow the three-axis robotic arm 4 to vacuum-adsorb the separated labels, confirm that the three-axis robotic arm 4 has adsorbed the labels, confirm that the product to be labeled has moved to the labeling area, and finally, automate the process of the three-axis robotic arm 4 affixing the labels to the product. The following is a detailed description of each component:
[0031] like Figure 2 , Figure 6As shown, the label peeling assembly 2 is specifically composed of: a support plate 201 assembled on the lower worktable 1, a feeding cylinder 202 and a take-up roller 203 arranged horizontally on the support plate 201, the take-up roller 203 being used to pull out the paper roll on the feeding cylinder 202, and several guide rollers 204 for guiding the paper roll between the feeding cylinder 202 and the take-up roller. The label peeling assembly 2 also includes a pull-out motor 207 that drives the take-up roller 203 to rotate and pull out, i.e., the working principle of the above-mentioned structure. The process involves placing a paper roll with a label attached into a loading cylinder 202, and then passing the paper roll sequentially through several guide rollers 204 until it finally attaches to a take-up roller 203. The take-up roller 203 is connected to a pull-out motor 207 via a chain connection or the output end of the pull-out motor 207 is directly connected to the take-up roller 203, thereby enabling the rotation of the take-up roller 203 (the pull-out motor 207 can be a stepper motor or controlled by a controller), which further drives the paper roll with the label attached to move and transport. To separate the label from the paper roll during transport, a separation group is provided between several guide rollers 204 and near the product transport group 3. The separation group includes a paper roll placement plate 205 and a label placement plate 206, with a gap between them. The label placement plate 206 is positioned below the paper roll placement plate 205. When the paper roll with the label attached is transported to the gap, the gap is limited to the passage of the paper roll. The label on the paper roll moves to the label placement plate 206 due to the inertia of the paper roll's movement. Initially, the loading cylinder 202 and a portion of the guide rollers 204 are positioned above the separation group, while the other... Part of the guide rollers 204 and the take-up rollers 203 are located below the peeling group. The paper rolls with labels attached will flow from above the peeling group through one of the guide rollers 204 above the peeling group, the gap, another part of the guide rollers 204 below the peeling group, and the take-up rollers 203 in sequence. The main design of this design is the gap design between the paper roll placement plate 205 and the label placement plate 206. First, the label placement plate 206 is located below the paper roll placement plate 205 and the gap between the two is set to be limited to the thickness of the paper roll. That is, the labels on the paper rolls move to the label placement plate 206 due to the inertia of the paper roll movement and wait for the three-axis robotic arm 4 to pick them up and transport them.
[0032] like Figure 2 , Figure 5As shown, the product transport group 3 is designed for transporting products to be labeled. Its specific structure is as follows: the product transport group 3 includes a transport platform 301, a transport line 303 for transporting products is provided in the middle of the transport platform 301, and the product transport group 3 also includes a transport motor 309 for driving the products placed on it to transport. The main feature of this design is that a height adjustment component 302 for adjusting the height of the adjuster is provided below the transport platform 301. The purpose is to make effective use of the space for adjustment while ensuring that the overall equipment is fixed and consistent, since there are various types of products to be labeled. Specifically, the height adjustment assembly 302 includes a base plate 304. Support guide rods 305 supporting the transport line 303 are mounted on the upper end of the base plate 304 and are located at its four corners. An adjusting guide rod 306 is located at the center of the support guide rod 305. The base plate 304 is positioned below the lower worktable 1. The worktable has sliding holes 101 for the support guide rods 305 and 306 to pass through. A bearing seat 102 is provided at the upper end of the worktable to ensure the stable up-and-down sliding of the support guide rods 305 and 306. The base plate 304 serves as the support for the support guide rods 305 and 306, and can be adjusted by moving the base plate 304 up and down. The synchronous movement of the support guide rod 305 and the adjusting guide rod 306 drives the up and down movement of the support guide rod 305. The support guide rod 305 is mainly used to support and fix the transport table 301. Its upper end is provided with a fixing block 307 that is fixed to the outer shell of the transport table 301. First, there are four fixing blocks 307, and the fixing blocks 307 are L-shaped profile plates, so that the fixing blocks 307 can support the bottom and outer side of the transport table 301, thereby ensuring the assembly is firm. The upper surface of the adjusting guide rod 306 is provided with a locking nut 308 that is threaded to it. The height adjustment component 302 is fixed on the lower worktable 1 by the locking nut 308.
[0033] The transport drive of the transport line 303 on the transport platform 301 is mainly achieved by setting a transport motor 309 on it, which is connected by a chain or directly to the drive shaft on the transport line 303.
[0034] like Figure 2 , Figure 3 , Figure 4As shown, the design of the three-axis robotic arm 4 includes a vertically oriented assembly base 401 mounted on the lower worktable 1. The assembly base 401 is equipped with an X-axis transmission guide rail 402. A motor is located at one end of the X-axis transmission guide rail 402. An X-axis slider assembly 403 that moves along the X-axis direction is mounted on the X-axis transmission guide rail 402. A Y-axis transmission guide rail 404 is externally connected to the X-axis slider assembly 403. A motor is located at one end of the Y-axis transmission guide rail 404. A Y-axis slider assembly 405 that moves along the Y-axis direction is mounted on the Y-axis transmission guide rail 404. A Z-axis transmission guide rail 406 is externally connected to the Y-axis slider assembly 405. A motor is located at the upper end of the Z-axis transmission guide rail 406. A Z-axis slider assembly 407 that moves along the Z-axis direction is mounted on the Z-axis transmission guide rail 406. A vacuum nozzle 407 that can take in and release air is mounted on the Z-axis slider assembly 407. A vacuum pump is externally connected to the vacuum nozzle 407 through a conduit. Its working principle is as follows: Motor 1 drives the X-axis slider group 403 on the X-axis transmission guide rail 402 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 group 405 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 group 407 to move up and down along the Z-axis, further increasing the positioning flexibility of the robotic arm in three-dimensional space and enabling precise up and down adjustment. A vacuum nozzle 407 for taking in and releasing air is installed at the end of the Z-axis slider group 407. When the robotic arm needs to move objects, the vacuum nozzle 407 uses a vacuum pump (not shown in the figure) to perform the adsorption function. The vacuum pump is connected to the vacuum nozzle 407 through a conduit. When adsorbing objects, a negative pressure is formed inside the vacuum nozzle 407, making the objects firmly attached to the nozzle, facilitating the robotic arm to move or place items. After the vacuum nozzle 407 has completed the handling, it can release the adsorbed objects through the air release function.
[0035] The design of the first vision group 5 and the second vision group 8 involves the first vision group 5 being assembled on the machine base between the label peeling group 2 and the product transport group 3, with its scanning direction upwards to detect whether the three-axis robotic arm 4 has received the label. The second vision group is assembled on the upper worktable 7, with its scanning direction downwards to detect whether the product on the product transport group 3 has been transported to the labeling position. This two-vision group design ensures the accuracy of the product labeling process.
[0036] In summary, the working principle of this utility model is as follows:
[0037] First, the paper roll with the label attached is placed on the loading cylinder 202 and flows through a portion of the guide roller 204, the label placement plate 206, and the gap between the paper roll placement plate 205 and the label placement plate 206. Then, it flows through another portion of the guide roller 204 and the receiving roller 203 below the peeling group to complete the placement. Then, the equipment is started by the control key 702 of the upper worktable 7. The pull-out motor 207 drives the label peeling group 2 to complete the separation of the paper roll and the label. The three-axis robotic arm 4 picks up the label and places it in the scanning area of the first vision group 5 for detection and confirmation. The transport line 303 transports the corresponding product to the scanning area of the second vision group 8 to wait for labeling. Finally, the three-axis robotic arm 4 attaches the label to the product. The display screen 701 is used to display the corresponding scan and data.
[0038] 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.
