Abstract
Description
Technical Field
[0001] This utility model belongs to the field of semiconductor industry strip product testing technology, specifically relating to an automatic labeling device. Background Technology
[0002] Currently, in the semiconductor industry, the main methods for marking NG (Not Good) products during the production of semiconductor tapes include laser marking, inkjet marking, and marker pen marking. However, these methods all have certain limitations:
[0003] Laser marking: Although it has the advantages of clear and permanent marking, the equipment cost is high, the system integration is complex, and it occupies a large installation space.
[0004] Inkjet marking: Although it has the advantage of non-contact marking, it poses a risk of ink pollution in practical applications, which can easily cause environmental and product surface pollution. At the same time, it requires high maintenance frequency and has high operating costs.
[0005] Marker pen marking: simple structure and low initial investment, but the pen tip is prone to drying out and wear, requiring frequent replacement or maintenance, affecting the stability of continuous production and resulting in poor marking consistency. Utility Model Content
[0006] This utility model aims to at least partially solve one of the technical problems in the related art.
[0007] Therefore, the technical solution adopted by this utility model is: an automatic labeling device, including a material tape product X-axis conveying device, a labeling X-axis moving device, and a labeling Y-axis moving device. The labeling Y-axis moving device is set on the labeling X-axis moving device. The labeling Y-axis moving device is equipped with a label tape winding assembly, a label tape unwinding assembly, and a lifting assembly. The lifting assembly is equipped with a label top release sheet and a pressure roller. The label tape is wound around the label tape unwinding assembly, and the free end of the label tape passes around one side of the label top release sheet and is connected to the label tape winding assembly.
[0008] The lifting assembly is equipped with a tag sensor.
[0009] The labeling Y-axis moving device is equipped with a guide block, a first guide wheel, a second guide wheel, a third guide wheel, and a U-shaped block. After the free end of the label tape leaves the label tape unwinding assembly, it passes around the guide block and through the U-shaped groove of the U-shaped block. Then, it passes around the first guide wheel, the second guide wheel, the side of the label top separation sheet, and the third guide wheel in sequence before connecting to the label tape winding assembly. A label presence / absence sensor is provided in the U-shaped groove of the U-shaped block.
[0010] Compared with existing technologies, this utility model has the following advantages: It adopts a modular design with independent functions and standardized interfaces, facilitating on-site debugging, replacement, and future upgrades. The label feeding process is fully integrated, including unwinding, rewinding, peeling, sensing, and anti-rewinding functions, resulting in a compact overall structure that is easy to maintain. This utility model is highly compatible, adaptable to various product specifications, and enables real-time marking of NG products, improving automation levels. This utility model is environmentally friendly and efficient, replacing traditional marking methods. Compared to laser marking, inkjet marking, or marker pen marking, this device offers advantages such as low cost, no pollution, and maintenance-free operation. The contact labeling process provides clear and easy-to-read markings, suitable for traceability system management. This device not only solves the problems of high cost, high pollution, and frequent maintenance associated with traditional marking methods, but also achieves stable, efficient, and environmentally friendly NG product marking through precision mechanical design and intelligent control.

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.
[0014] Conversely, this application covers any alternatives, modifications, equivalent methods, and schemes made within the spirit and scope of this application as defined by the claims. Furthermore, to provide the public with a better understanding of this application, certain specific details are described in detail below. However, this application can be fully understood by those skilled in the art even without these detailed descriptions.
[0015] See Figures 1-2 An automatic labeling device includes a product X-axis conveying device 1, a labeling X-axis moving device 2, and a labeling Y-axis moving device 3. The labeling Y-axis moving device 3 is mounted on the labeling X-axis moving device 2. The labeling Y-axis moving device 3 is equipped with a label tape winding assembly 4, a label tape unwinding assembly 5, and a lifting assembly 6. The lifting assembly 6 is equipped with a label top release sheet 7 and a pressure roller 8. The label tape is wound around the label tape unwinding assembly 5, and the free end of the label tape passes around one side of the label top release sheet 7 and is connected to the label tape winding assembly 4.
[0016] The lifting assembly 6 is equipped with a tag sensor 9.
[0017] The second guide wheel 12 is positioned above the label top plate 7.
[0018] The labeling Y-axis moving device 3 is equipped with a guide block 10, a first guide wheel 11, a second guide wheel 12, a third guide wheel 13, and a U-shaped block 14. After the free end of the label tape leaves the label tape unwinding assembly 5, it passes around the guide block 10 and then through the U-shaped groove of the U-shaped block 14. It then passes around the first guide wheel 11, the second guide wheel 12, one side of the label top deflector 7, and the third guide wheel 13 in sequence before connecting with the label tape winding assembly 4. A label presence / absence sensor 15 is provided in the U-shaped groove of the U-shaped block 14.
[0019] In operation, the X-axis conveyor 1 of this invention conveys the tape product. The X-axis labeling moving device 2 and the Y-axis labeling moving device 3 move to position the label top release plate 7 and the pressure roller 8 directly above the conveyed tape product. The label tape winding assembly 4 and the label tape unwinding assembly 5 are also present. The label top release plate 7 presses against the label roll and lifts one end of a label on the label roll, separating one end of the label from the label roll. The label sensor 9 detects that one end of the label has been lifted. Then, the lifting assembly moves the label top release plate 7 and the pressure roller 8 downward. At this time, the lifted end of the label moves downward and is attached to the tape product. The lifting assembly continues to move downward, so that the pressure roller contacts the label. Then, the X-axis labeling moving device 2 moves along the moving direction of the tape product, so that the pressure roller completely presses the label onto the tape product.
[0020] The label presence / absence sensor 15 is used to detect whether there is a label on the label roll. When no label is detected, the label roll on the label roll unwinding assembly 5 is replaced in time.
[0021] Labeling components:
[0022] This device, through precise matching, ensures that the label is accurately peeled off at the designated position and attached to the corresponding position on the NG product, and has high stability and continuous working capability.

[0024] The labeling Y-axis moving device consists of a cylinder and a linear guide rail, enabling movement in the Y direction. This structure offers fast response and stable operation, ensuring adaptability to various widths and thicknesses of strip products.
[0025] The X-axis conveyor for the strip products uses a servo motor-driven pinwheel for precise stepping feeding, achieving smooth and synchronous conveying of the strip. The structure is highly compatible, adaptable to strip products of various widths and thicknesses, and enables real-time marking of defective products.
[0026] High-precision positioning ensures accurate labeling.
[0027] The labeling X-axis is driven by a high-precision ball screw module, with a repeatability accuracy of ±0.1mm, meeting the high-precision labeling requirements under high-speed operation.
