Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, specifically a four-head high-speed vision 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] Existing labeling machines mostly use a single-head adsorption method during transportation, which involves adsorbing the label and then transporting it to the product. This labeling method is often inefficient, especially for labeling small products transported on belts. Therefore, a high-efficiency visual labeling machine needs to be designed.

[0029] 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.

[0030] refer to Figures 1 to 8 As shown in the accompanying drawings and specific embodiments, further explanation will be provided below:

[0031] This technical solution is mainly designed with an upper workbench 102 as the carrier, equipped with a label peeling group 2, a product transport group 3, and a three-axis robotic arm 4. The purpose is to automatically separate the labels from the paper rolls during transport; the three-axis robotic arm 44 vacuum-adsorbs the separated labels, confirms that the robotic arm 44 has adsorbed the labels, confirms that the product 305 to be labeled has moved to the labeling area, and finally, the three-axis robotic arm 44 completes the automated process of affixing the labels to the product 305. This technology is specifically designed for transporting small, belt-type products 305 as shown in the attached diagram, and achieves high-efficiency labeling operations through four vacuum nozzles 413.

[0032] Specific

[0033] Firstly, regarding the structural design of the three-axis robotic arm 4: The three-axis robotic arm 4 includes a vertically oriented assembly base 401. An X-axis transmission guide rail 402 is mounted on the assembly base 401. A motor is located at one end of the X-axis transmission guide rail 402. An X-axis slider assembly 403, which 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, which moves along the Y-axis direction, is mounted on the Y-axis transmission guide rail 404. The Y-axis slider assembly 405 is connected to a connecting plate 406. Four drive motors 407 are located on the upper back of the connecting plate 406. An active gear shaft 408, connected to the corresponding drive motor 407, is located on the upper front of the connecting plate 406. A driven gear shaft 408 is located on the lower front of the connecting plate 406. The gear shaft 409, the axis of the driving gear shaft 408 and the axis of the driven gear shaft 409 are perpendicular to each other. A vertical slide rail 410 is provided on this vertical line. A transmission belt 411 is sleeved on the driving gear shaft 408 and the driven gear shaft 409. A vertical slider 412 is provided on one side of the transmission belt 411 and assembled on the vertical slide rail 410. A vacuum nozzle 413 for taking in and releasing air is provided on the front of the vertical slider 412. A vacuum pump is connected to the vacuum nozzle 413 through a conduit. At the same time, a bearing 414 matching the rotation of the driving gear shaft 408 is provided on the connecting plate 406. The output end of the drive motor 407 passes through the bearing 414 and is connected to the driving gear shaft 408. A shaft rod 415 fixed by the connecting plate 406 is provided on the axis of the driven gear shaft 409. The driven gear shaft 409 rotates around the shaft rod 415. 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 direction, which allows the robotic arm to move back and forth on the worktable in the horizontal direction; Motor 2 drives the Y-axis slider group 403 to move vertically along the Y-axis direction, which allows the robotic arm to be adjusted in the vertical direction, providing a larger operating space. At the same time, through the assembly and cooperation of four corresponding drive motors 407, drive gear shaft 408, driven gear shaft 409, transmission belt 411, vertical slide rail 410, and vertical slider 412 on the connecting plate 406, the vacuum nozzle 413 set on the vertical slider 412 can be driven to move up and down, thereby transporting the label. The suction and release of the vacuum nozzle 413 are accomplished by a vacuum pump (not shown in the figure) connected to the outside of the conduit.

[0034] For small-sized, specific products transported via mode 305, the designated product transport group 3 is as follows:

[0035] Product transport group 3 includes a transport platform 301 and a transport motor 302. The transport platform 301 has a slot 303 with an opening at the top, extending from the inlet to the outlet. A flat belt 304 is placed in the slot 303, and products 305 are arranged in a row on the flat belt 304. Holes 306 are arrayed on the side end of the flat belt 304. The transport motor 302 is assembled on the side of the transport platform 301. A gear component 307 is connected to the output end of the transport motor 302. The teeth arrayed on the gear component 307 are protrusions 308 that can be inserted into the holes 306. The lower worktable 1 is provided with a connection for the protrusions 308 on the gear component 307. The notch 309 contacts the hole 306. The transport motor 302 is a stepper motor. When the transport motor 302 is driven, the rear protrusion 308 corresponds to the rear hole 306 to form a transport. The principle is as follows: the product 305 and the flat belt 304 are placed in the slot 303 and driven by the transport motor 302, so that the tooth angle on the gear 307 is aligned with the hole 306 on the flat belt 304 through the notch 309. This stepper drive can form a transmission. The opening at the upper end of the slot 303 exposes the product 305, which makes it easy for the three-axis robotic arm 4 to attach the label to the corresponding product 305.

[0036] The label peeling assembly 2 is specifically composed of: a support plate 201 assembled on the lower workbench 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. Several guide rollers 204 for guiding the paper roll are provided 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. The working principle of the above structure is as follows: The paper roll with the label attached is placed into the loading cylinder 202 and passed through several guide rollers 204 in sequence, and finally attached to the receiving roller 203. The receiving roller 203 is connected to the pull-out motor 207 by a chain or the output end of the pull-out motor 207 is directly connected to the receiving roller 203, thereby realizing the rotation of the receiving roller 203 (the pull-out motor 207 can be a stepper motor, or the pull-out motor 207 can be controlled by a controller), so as to further drive 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 roller 204 and the take-up roller 203 are located below the peeling group. The paper roll with the label 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 roller 204 below the peeling group, and the take-up roller 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 label on the paper roll moves to the label placement plate 206 due to the inertia of the paper roll movement and waits for the three-axis robotic arm 4 to pick it up and transport it.

[0037] Meanwhile, a first vision group 101 is also provided on the lower worktable 1 between the label peeling group 2 and the product transport group 3. The scanning direction of the first vision group 101 is upward, which is used to detect whether the three-axis robotic arm 4 has received the label.

[0038] A protective panel is provided on the upper side of the lower workbench 1. An upper workbench 102 is provided on the upper part of the protective panel. A second vision group 103 is provided on the upper workbench 102. The scanning direction of the second vision group 103 is downward, and it is used to detect whether the product 305 on the product transport group 3 has been transported to the labeling position.

[0039] Furthermore, the first vision group 101 includes a vertical profile, from which a camera 104 and an annular frame 105 are distributed. The inner wall of the annular frame 105 is surrounded by a light source 106, which is used by the camera 104 to clearly detect the label attached to the three-axis robotic arm 4, thereby improving the scanning accuracy. The lower worktable 1 is provided with a lighting frame 310 located on the side of the transport table 301. The lighting frame 310 illuminates the labeling position of the product 305, which is used by the second vision group 103 to clearly detect the product 305 moving to the corresponding position.

[0040] 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.
