Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, specifically to automated label peeling and pasting equipment. Background Technology

[0002] Labeling machines are devices that attach rolls of self-adhesive labels (paper or metal foil) to PCBs, products, or specified packaging. As an important part of modern packaging, labeling machines not only improve production efficiency but also ensure the accuracy and consistency of product labels. Currently, the types of labeling machines produced in my country are gradually increasing, and the technical level has also greatly improved. The backward situation of manual and semi-automatic labeling has been transformed into a situation where automated high-speed labeling machines occupy a large market share. However, when labeling products, the label paper needs to be transferred to the labeling machine through a label transfer mechanism so that it can be used for subsequent product labeling. However, the following points need to be considered in the design of the label transfer mechanism: (1) The paper rolls with the labels need to be separated during transportation. If manual methods are used, the cost will be too high; (2) When transporting labels automatically, it is necessary to ensure that the labels have been absorbed during transportation so that they can be used for subsequent labeling on the products.

Detailed Implementation

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] 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.

[0019] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: refer to Figures 1 to 6As shown, the automated label peeling and pasting equipment includes a 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; the worktable is also equipped with a three-axis robotic arm 3 that transports along the XYZ directions for receiving and transporting the peeled labels; the worktable is also equipped with a vision unit 4, which scans upwards to detect whether the three-axis robotic arm 3 has received the labels.

[0020] The technical solution is designed with a workbench 1 as the supporting component. The workbench 1 houses the main label peeling unit 2 for transporting the roll of paper and separating the labels from it. A three-axis robotic arm 3 is used to transport the labels, and a vision unit 4 is included to detect whether the three-axis robotic arm 3 has a label attached to it. Specifically... refer to Figure 2As shown, the label peeling assembly 2 specifically comprises a support plate 5 assembled on a workbench 1. A feeding cylinder 6 and a take-up roller 7 are arranged horizontally on the support plate 5. The take-up roller 7 is used to pull out the paper roll from the feeding cylinder 6. Simultaneously, several guide rollers 8 are provided between the feeding cylinder 6 and the take-up roller for guiding the paper roll. The label peeling assembly 2 also includes a pull-out motor 12 that drives the take-up roller 7 to rotate and pull out. This describes the working principle of the above-described structure. The process involves placing a paper roll with a label attached into a loading cylinder 6, and then passing the paper roll through several guide rollers 8 in sequence, finally attaching it to a receiving roller 7. The receiving roller 7 is connected to the pull-out motor 12 via a chain or the output end of the pull-out motor 12 is directly connected to the receiving roller 7, thereby enabling the rotation of the receiving roller 7 (the pull-out motor 12 can be a stepper motor, or the pull-out motor 12 can be 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 8 and near the product transport group. The separation group includes a paper roll placement plate 9 and a label placement plate 10, with a gap 11 between them. The label placement plate 10 is positioned below the paper roll placement plate 9. When the paper roll with the label attached is transported to the gap 11, the gap is limited to the paper roll's passage. The label on the paper roll moves to the label placement plate 10 due to the inertia of the paper roll's movement. Initially, the loading cylinder 6 and a portion of the guide rollers 8 are positioned above the separation group, while the other... Part of the guide roller 8 and the take-up roller 7 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 8 above the peeling group, the gap 11, another part of the guide roller 8 below the peeling group, and the take-up roller 7 in sequence. The main design of this design is the gap 11 between the paper roll placement plate 9 and the label placement plate 10. First, the label placement plate 10 is located below the paper roll placement plate 9 and the gap 11 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 10 due to the inertia of the paper roll movement and waits for the three-axis robotic arm 3 to pick it up and transport it.

[0021] The design of the three-axis robotic arm 3 includes a vertically oriented assembly base 13, an X-axis drive rail 14 on the assembly base 13, a motor 15 at the end of the X-axis drive rail 14, an X-axis slider assembly 16 that moves along the X-axis direction on the X-axis drive rail 14, a Y-axis drive rail 29 connected externally to the X-axis slider assembly 16, a motor 17 at one end of the Y-axis drive rail 29, a Y-axis slider assembly 30 that moves along the Y-axis direction on the Y-axis drive rail 29, a Z-axis drive rail 18 connected externally to the Y-axis drive rail 18, a motor 19 at the upper end of the Z-axis drive rail 18, a Z-axis slider assembly 31 that moves along the Z-axis direction on the Z-axis drive rail 18, a vacuum nozzle 20 for taking in and releasing air on the Z-axis slider assembly 31, and a vacuum pump connected externally to the vacuum nozzle 20 through a conduit. Its working principle is as follows: Motor 15 drives the X-axis slider group 16 on the X-axis transmission guide rail 14 to move horizontally along the X-axis, allowing the robotic arm to move back and forth on the worktable 1 in the horizontal direction; Motor 2 17 drives the Y-axis slider group 30 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 19 drives the Z-axis slider group 31 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 20 for taking in and releasing air is installed at the end of the Z-axis slider group 31. When the robotic arm needs to move objects, the vacuum nozzle 20 uses a vacuum pump (not shown in the figure) to perform the adsorption function. The vacuum pump is connected to the vacuum nozzle 20 through a conduit. When adsorbing objects, a negative pressure is formed inside the vacuum nozzle 20, making the objects firmly attached to the nozzle, facilitating the robotic arm to move or place items. After the vacuum nozzle 20 has completed the handling, it can release the adsorbed objects through the air release function.

[0022] Furthermore, a vertical plate 21 is provided on the outer side of the Y-axis slider assembly 29. The Z-axis transmission guide rail 29 and the motor 319 are located on the vertical plate 21, and the output end of the motor 319 is provided with a drive gear shaft 22. A driven gear shaft 23 is provided at the lower end of the vertical plate 21. A transmission belt 24 is sleeved between the drive gear shaft 22 and the driven gear shaft 23. A connecting block 25 connected to the Z-axis slider assembly 31 is provided on one side of the transmission belt 24. The Z-axis transmission guide rail 18 consists of two sets of symmetrically arranged axes of the drive gear shaft 22 and the driven gear shaft 23, located on the outer side of the transmission belt 24. The Z-axis slider assembly 31 assembled on the Z-axis transmission guide rail 18 and the connecting block 25 between the Z-axis slider assembly 31 and the transmission belt 24 are respectively set in two sets. Its working principle is: through the vertical plate The vertical plate 21 serves as a support plate. A motor 319 is mounted on the back of the vertical plate 21, passing through the vertical plate 21 and connected to a drive gear shaft 22. A driven gear shaft 23 is located at the lower end of the vertical plate 21. A transmission belt 24 (using a toothed connection) is fitted between the drive gear shaft 22 and the driven gear shaft 23. The motor 319 drives the transmission belt 24, which in turn moves. Two connecting blocks 25 on the left and right sides of the transmission belt 24 connect to a Z-axis slider assembly 31 mounted on the Z-axis transmission guide rail 18. This allows two sets of vacuum nozzles 20 mounted on the Z-axis slider assembly 31 to move alternately up and down. This principle primarily involves adsorbing two labels at a time, thereby reducing the travel path of the three-axis robotic arm 3 and improving work efficiency. The two-axis transport of the three-axis robotic arm 3 is achieved using an existing slide table mechanism.

[0023] The structure design of vision group 4 includes a vertical profile 26 assembled inside the workbench 1 and passing through the upper surface of the workbench 1. The vertical profile 26 is assembled with a camera 27 and a projection lens 28 from bottom to top. The camera 27 is used to take pictures, and the projection lens is used to focus. The main feature of this structure is that the vertical profile 26 is assembled on the workbench 1, which facilitates easy assembly and disassembly.

[0024] 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.
