Description

Technical Field

[0001] The utility model relates to the technical field of tape coding, and in particular, to a tape coding device and its signal acquisition component. Background Art

[0002] The two-dimensional code coding technology for easy-open lids is a key link to ensure product traceability and anti-counterfeiting. In the traditional two-dimensional code coding process for easy-open lids, an angle encoder of a punching machine is usually used to calculate and provide an angle signal to the coding device.

[0003] This static coding mode relies on the accuracy of the angle encoder. Since the encoder is vulnerable to factors such as electromagnetic interference, mechanical vibration, and light changes in a complex industrial environment, there are errors in the calculated static angle. This error will directly affect the printing quality of the two-dimensional code, causing the two-dimensional code to be deformed, blurred, or even unrecognizable, thus affecting the appearance quality of the product, reducing the market competitiveness of the product, and possibly having an adverse impact on the traceability and anti-counterfeiting functions of the product.

[0004] In addition, rework and waste caused by two-dimensional code quality problems will also reduce production efficiency and economic benefits. Therefore, the existing two-dimensional code coding technology for easy-open lids urgently needs a more accurate and stable signal acquisition method to improve the accuracy and reliability of coding, ensure the quality of the two-dimensional code, and enhance the market competitiveness of the product.

Detailed Embodiments

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] Example 1. As Figures 1 to 5 shown, an embodiment of the present utility model provides a tape coding device, which includes a feeding assembly, a driving assembly, and a position signal acquisition assembly. The feeding assembly is provided with a feeding channel 10 for the tape to move, for conveying the tape 2 to be coded. The feeding assembly includes a feeding wheel 1 for driving the tape in the feeding channel 10 to move. The driving assembly is configured to intermittently drive the feeding wheel 1 to rotate.

[0036] The position signal acquisition assembly includes a driving synchronous disk 11 engaged with the feeding wheel 1 and a detection member. The tape synchronous disk is provided with at least one induction groove 12. The detection member is configured to detect the induction groove 12. The induction groove 12 is configured to be detected by the detection member when the feeding wheel 1 stops rotating.

[0037] Specifically, the driving synchronous disk 11 realizes a light and dark segment design through the induction groove 12. Light can pass through the light segment part, while the dark segment part blocks light. Therefore, when the photoelectric sensor 13 passes through these alternately light and dark induction grooves 12, clear pulse signals can be generated, thereby realizing precise detection of the tape position. This design not only improves the accuracy of position detection, but also enables the system to better resist external interference, ensuring the stability and reliability during the tape coding process.

[0038] A coding device for a strip of the present utility model significantly improves the signal acquisition accuracy and system stability of a two-dimensional code coding device. By directly detecting the stationary position of the driving synchronous disk 11 with a detection member, the influence of factors such as electromagnetic interference, mechanical vibration, and light change on a traditional angle encoder in a complex environment is effectively avoided, thereby greatly reducing the signal error. This high-precision signal acquisition method not only ensures the printing quality of the two-dimensional code, avoids problems such as deformation, blurring, or unrecognizability of the two-dimensional code caused by signal error, but also enhances the product traceability and anti-counterfeiting functions.

[0039] Based on the above embodiments, in an alternative embodiment of the present utility model, as Figure 3 and Figure 4 shown, the induction groove 12 includes a first induction portion and a second induction portion 16. The width of the second induction portion 16 is greater than that of the first induction portion. Preferably, both the first induction portion and the second induction portion 16 are configured as rectangular structures.

[0040] Specifically, in this configuration, the width difference between the first induction portion and the second induction portion 16 can provide a more distinct signal change for the detection member, thereby improving the accuracy of position detection. Such a design not only enhances the reliability of signal acquisition but also allows the system to more accurately identify the stationary position of the strip, further optimizing the accuracy and efficiency of the coding process. In addition, the induction groove 12 with a rectangular structure simplifies the manufacturing process, reduces costs, and is also convenient for maintenance and replacement, making the entire strip coding device more practical and economical.

[0041] In other embodiments, in order to further improve the accuracy and reliability of signal acquisition, the induction groove 12 can be designed in different shapes and sizes to adapt to different detection requirements. For example, the induction groove 12 can be a rectangular, trapezoidal, or other polygonal structure to provide richer signal characteristics.

[0042] Based on the above embodiments, in an alternative embodiment of the present utility model, as Figure 3 and Figure 4 shown, the driving synchronous disk 11 is configured as a disk-shaped structure. The induction groove 12 is provided on the periphery of the driving synchronous disk 11. Preferably, the number of the induction grooves 12 is at least two. At least two of the induction grooves 12 are circumferentially and uniformly distributed on the driving synchronous disk 11.

[0043] Such a design can ensure that the position of the material belt is evenly detected on the entire circumference, so that a consistent detection signal can be obtained regardless of the position of the material belt. In this embodiment, the number of sensing slots 12 is 8, and the feeding wheel 1 needs to pause 8 times for each rotation. In other embodiments, it can be stopped once, twice or four times, and the number of times is equally divided by the number of sensing slots 12, and the present invention does not make specific limitations on this. Through the redundant design of the sensing slots 12, the material belt coding device can adapt to the large-code requirements of more types of material belts.

[0044] Based on the above embodiments, in an optional embodiment of the present invention, as Figure 3 and Figure 5 As shown, the detection component includes a photoelectric sensor 13 for detecting the sensing slot 12, and a sensor bracket 14 for fixing the photoelectric sensor 13. Preferably, the photoelectric sensor 13 is a U-shaped laser sensor.

[0045] In this optional embodiment, the U-shaped laser sensor has the characteristics of high sensitivity and fast response due to its unique U-shaped structure. This sensor can determine whether an object passes through or exists in the detection area by detecting the high and low level changes of the output signal. This sensor has the advantages of fast response speed, high accuracy, and non-contact detection, and is widely used in automated production lines, object counting, position detection and other fields. In addition, U-shaped laser sensors have high-precision measurement capabilities, can measure on objects moving at high speed, and can measure the position of objects in a very short time. This makes them very suitable for applications that require fast measurement, and can provide accurate and reliable signal acquisition to ensure high efficiency and high quality of the coding process.

[0046] Based on the above embodiments, in an optional embodiment of the present invention, as Figure 1 As shown, the driving assembly includes a dividing box 3, a coupling 4, a first pulley 8, a second pulley and a synchronous belt 7. The output end of the dividing box 3 is connected to the feeding wheel 1. The coupling 4 is used to connect the first pulley 8 to the input end of the dividing box 3. The second pulley is used to connect the crankshaft 5 of the punch press. The synchronous belt 7 is used to drive and connect the first pulley 8 and the second pulley. Preferably, the material belt coding device also includes a laser coding assembly 9. The laser coding assembly 9 is used to code on the material belt when the material belt is stationary.

[0047] Specifically, the driving component can be driven by the power of the stamping machine tool without the need for additional power. And their movement frequencies are the same. In one stamping cycle of the stamping machine tool, the feeding wheel 1 rotates by a certain angle, thereby driving the strip to move forward by a certain distance, making their beats the same. The position signal acquisition component can accurately capture the moment when the feeding wheel 1 stops. At this moment, it sends a signal to make the strip coding device code on the strip, ensuring that the coded image is clear.

[0048] For the strip coding device of the embodiment of the present utility model, by directly detecting the static position of the driving synchronous disk 11 using the position signal acquisition component, the influence of factors such as electromagnetic interference, mechanical vibration, and light change on the traditional angle encoder in a complex industrial environment is effectively avoided. Thus, the signal error is greatly reduced, and the accuracy of signal acquisition and the stability of the system are improved.

[0049] Secondly, the structural design of the present invention allows the induction groove 12 to be accurately detected by the detection component when the feeding wheel 1 stops rotating. This design improves the signal acquisition accuracy of the two-dimensional code coding device, ensures the printing quality of the two-dimensional code, avoids problems such as deformation, blurring, or unrecognizability of the two-dimensional code caused by signal errors, and enhances the product traceability and anti-counterfeiting functions.

[0050] In addition, the design of the strip coding device of the present invention takes into account the efficiency requirements of industrial production. By reducing rework and waste caused by two-dimensional code quality problems, the production efficiency and economic benefits are improved. At the same time, the introduction of the laser coding component 9 enables the coding operation to be carried out in a state where the strip is completely stationary, further improving the coding accuracy and quality.

[0051] In summary, through its unique technical solution, the present invention realizes the innovation of the strip coding technology, provides a coding device with a simple structure, convenient operation, and high cost-effectiveness, and has good market application prospects.

[0052] Embodiment 2. As Figures 3 to 5 shown, the present application further provides a position signal acquisition component of a strip coding device, which includes a driving synchronous disk 11 that can be engaged with the feeding wheel 1 of the strip coding device, and a detection component for detecting the position of the indexing disk. The strip synchronous disk is provided with at least one induction groove 12. The detection component is configured to be suitable for detecting the induction groove 12. The induction groove 12 is configured to be detectable by the detection component when the feeding wheel 1 stops rotating.

[0053] As Figures 3 to 5 shown, the induction groove 12 includes a first induction part and a second induction part 16. The width of the second induction part 16 is greater than that of the first induction part. Preferably, both the first induction part and the second induction part 16 are configured as rectangular structures.

[0054] Based on the above embodiments, in an optional embodiment of the present utility model, as Figure 3 and Figure 5 shown, the detection member includes a photoelectric sensor 13 for detecting the induction groove 12, and a sensor bracket 14 for fixing the photoelectric sensor 13 to an external object. Preferably, the photoelectric sensor 13 is a U-shaped laser sensor.

[0055] As Figure 3 and Figure 4 shown, the drive synchronizing disk 11 is configured as a disk-shaped structure. The induction groove 12 is provided on the periphery of the drive synchronizing disk 11. Preferably, the number of the induction grooves 12 is at least two. At least two of the induction grooves 12 are circumferentially and uniformly distributed on the drive synchronizing disk 11.

[0056] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications.
