Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic label peeling production equipment, and in particular to a rear-removal label peeling mechanism. Background Technology
[0002] A label peeler is a mechanism used in the labeling process to peel labels off label strips one by one and attach them to the corresponding products. In automated label peeling and attaching systems, visual inspection is one of the key technologies for achieving precise positioning and stable peeling. Traditional label peeling mechanisms typically rely on external vision systems to detect label positions and control the movement of the peeling blade to separate the labels. However, existing technologies have the following significant problems:
[0003] 1. Because some label tapes are light in color or similar to the surface color of the peeler, the vision system has insufficient contrast when capturing the label edges or positioning features, making it unable to accurately identify the actual position of the label, which seriously affects the peeling accuracy and system reliability.
[0004] 2. To improve recognition performance, some systems require the addition of auxiliary light sources outside the label-peeling mechanism. This not only increases the complexity of the mechanism and the space required for installation, but also makes it difficult to achieve a stable and consistent lighting effect on labels of different materials or colors due to the fixed position of the light source and its susceptibility to ambient light interference, thus limiting the applicability and scalability of the equipment. Utility Model Content
[0005] To overcome the shortcomings of the prior art, the present invention aims to provide a retraction label-removing mechanism.
[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: a retractable label peeling mechanism, comprising: a movable support and a lead screw stepper motor drive module for reciprocating movement of the movable support, the movable support being provided with a peeling blade, the peeling blade having a receiving cavity, a light source module being provided in the receiving cavity, the label passing through the light-emitting area of the light source module and corresponding to an external visual inspection unit, the label being illuminated by the light-emitting area, so that the visual inspection unit can clearly detect the outline of the label.
[0007] Preferably, the inner sidewall of the cavity has a convex edge forming an inner cavity, the light source module is located inside the inner cavity, and the sidewall of the cavity has a wire-passing groove.
[0008] Preferably, the light source module includes a backlight panel disposed in the inner cavity and a light-transmitting panel that contacts the top surface of the convex edge. The light-emitting area of the backlight panel faces the light-transmitting panel, and light is emitted through the light-transmitting panel.
[0009] Preferably, the light-transmitting panel is made of a high-transmittance material.
[0010] Preferably, the movable bracket is provided with an L-shaped connecting plate, and the L-shaped connecting plate has a mounting position for connecting with the lead screw stepper motor drive module.
[0011] Compared with the prior art, the advantages of this utility model are:
[0012] This utility model provides a rear-removal label peeling mechanism that innovatively integrates a light source module inside the peeling blade, effectively solving the visual recognition difficulties caused by the similarity between the label and background colors in existing technologies. It significantly improves visual recognition accuracy and stability. By placing the light source module inside the peeling blade, light is directly and evenly illuminating the label surface, greatly enhancing the contrast between the label and the background. This ensures that the visual inspection unit can clearly capture the label outline and features, thereby improving positioning accuracy and the reliability of the peeling action. The compact structure avoids reliance on external light sources. The built-in light source design eliminates the need for additional external light sources in traditional systems, simplifying the overall mechanical structure, reducing installation complexity and cost, and avoiding problems such as susceptibility to environmental interference and wiring difficulties associated with external light sources.

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0017] Please see Figure 1 and Figure 2This embodiment provides a retractable label peeling mechanism 100, which is installed on a label peeling machine 1000. It includes a movable support 1, which consists of two side plates 10, two sliding plates 11, a fixed column 12, a bottom paper guide shaft 13, and an L-shaped connecting plate 14. The two side plates 10 are spaced apart. The fixed column 12, the bottom paper guide shaft 13, and the L-shaped connecting plate 14 are respectively fixed between the two side plates 10, so that the two side plates 10 are parallel. The two sliding plates 11 are respectively fixed to the bottom of the two side plates 10. The two sliding plates 11 slide in cooperation with the guide rail on the label peeling machine 1000. The label peeling machine 1000 is provided with a screw stepper motor drive module 2 connected to the mounting position on the L-shaped connecting plate 14. The screw stepper motor drive module 2 pushes the movable support 1 to move back and forth along the guide rail to realize forward and backward movement, and to perform feeding and retractable peeling.
[0018] Furthermore, in this embodiment, the lead screw stepper motor drive module 2 includes a lead screw stepper motor 20, and a lead screw moving seat 21 is connected to the lead screw of the lead screw stepper motor 20. The lead screw moving seat 21 is provided with a flange mounting seat 22 that is connected to the mounting position of the L-shaped connecting plate 14. The mounting position is provided with multiple connecting holes, and the flange mounting seat 22 is provided with mounting holes corresponding to the connecting holes. The L-shaped connecting plate 14 and the flange mounting seat 22 are fixedly connected by bolts passing through the connecting holes and mounting holes.
[0019] Please see Figure 3 In this example, the top of the two side plates 10 are fixedly connected to a peeling blade 3 for peeling the label from the backing paper. The peeling blade 3 has a receiving cavity 30, and a light source module 4 is provided inside the receiving cavity 30. The inner sidewall of the receiving cavity 30 has a protruding edge 31, the thickness of which is less than the height of the receiving cavity 30, so that the protruding edge 31 surrounds the inner cavity. The light source module 4 includes a backlight plate 40 disposed in the inner cavity and a light-transmitting plate 41 that contacts the top surface of the protruding edge 31. The top surface of the light-transmitting plate 41 is on the same horizontal plane as the top surface of the sidewall of the receiving cavity 30. The light-emitting area of the backlight plate 40 faces the light-transmitting plate 41. The light is emitted through the light-transmitting plate 41. The label passes through the light-emitting area of the light source module 4 and corresponds to the external visual inspection unit. The label is illuminated by the light-emitting area, so that the visual inspection unit can clearly detect the label outline. By integrating the light source module 4 onto the peeling blade 3, this design saves space and improves the collaborative efficiency of label peeling and inspection. In actual operation, when the movable bracket 1 moves the peeling blade 3 to perform the peeling operation, the light source module 4 works synchronously, and the backlight panel 40 emits uniform and stable light, which is accurately illuminating the label through the light-transmitting plate 41. The light-transmitting plate 41 is on the same horizontal plane as the top surface of the side wall of the receiving cavity 30, ensuring the flatness of the emitted light and avoiding light scattering or obstruction caused by height differences. This effectively reduces the generation of shadows, thus providing a clear and interference-free label image for the external visual inspection unit. This allows the visual inspection unit to accurately and quickly identify the label outline, greatly improving the accuracy and efficiency of the entire label peeling and inspection process.
[0020] Furthermore, a wire-passing slot 32 is provided on the side wall of the receiving cavity 30. This slot facilitates the wire passing through the stripper 3 and connecting it to the backlight plate 40 for electrical conduction, avoiding potential tangling or pulling problems during the movement of the stripper 3 and ensuring the stability and safety of the wire connection. This design prevents the wire from wearing out or breaking due to frequent movement during long-term operation of the label-stripping mechanism 100, thereby extending the equipment's service life and reducing maintenance costs.
[0021] In an optional embodiment, the light-transmitting plate 41 is made of a high-transmittance material, such as PMMA (acrylic) or PC (polycarbonate). Both materials have excellent optical properties, with a light transmittance of over 90%, which minimizes light loss during transmission and ensures uniform and sufficient light intensity illuminating the label. Simultaneously, PMMA and PC materials also possess good impact resistance and weather resistance, making them less prone to cracking or deformation due to external impacts or environmental changes. This further ensures the stability and reliability of the light-transmitting plate 41 during use, continuously providing high-quality label illumination for the label-peeling mechanism 100, effectively reducing shadows and improving the accuracy of visual inspection.
[0022] In summary,
[0023] The rear-removal label-peeling mechanism 100 provided by this utility model solves the problems in visual recognition by integrating the light source module 4 inside the peeling blade 3, effectively optimizing the structure, controlling costs, and improving operational stability. Its compact design saves production space, simplifies the installation process, and reduces the initial investment and subsequent maintenance costs for enterprises. Simultaneously, the built-in light source module 4 avoids interference and wiring problems that may arise from external light sources, ensuring stable operation of the equipment in complex industrial environments. In practical applications, the high-transmittance material light-transmitting plate 41 combined with uniform and stable light output provides the visual inspection unit with clear and accurate label images, thereby significantly improving the accuracy and efficiency of label removal detection. Furthermore, the design of the wire passage slot 32 reflects the designer's attention to detail, effectively avoiding wire tangling or pulling problems, further enhancing the reliability and durability of the equipment. Therefore, the rear-removal label-peeling mechanism 100 of this utility model undoubtedly provides a highly efficient, stable, and reliable solution for related industries.
[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
