Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of logistics transportation status monitoring, and particularly relates to a production method and a status display for an item impact status monitoring chip Background Art
[0002] In the field of item impact, shock, drop and vibration monitoring, as a core component, the performance of the monitoring chip directly affects the accuracy and reliability of monitoring. The existing structure of the monitoring chip generally includes a transparent outer color display tube and a colored agent emulsion containing tube inserted into the outer color display tube. The monitoring of physical events is realized through the interaction between the color display coating on the inner surface of the outer color display tube and the colored agent emulsion
[0003] However, the existing monitoring chips have significant defects in assembly and sealing. For one type of product, the outer color display tube and the colored agent emulsion containing tube are respectively tube bodies with one end blind-ended, and then fixed by an adhesive. Its typical structure is the sleeve type vibration monitor disclosed in Chinese Patent CN2656978Y. This device includes a transparent outer color display tube and an internal colored agent emulsion containing tube, and is assembled and sealed by a glue bonding method. For another type, after the outer color display tube and the colored agent emulsion containing tube are independently cut, both ends are respectively sealed by filling with glue
[0004] The existing technology has the following defects
[0005] 1. Insufficient sealing reliability: During transportation and use, due to factors such as vibration, high temperature, acid-base corrosion, etc., micro-cracks are likely to occur at the adhesive interface under the vibration load during transportation, resulting in failure, leading to leakage of the colored agent emulsion and false alarms. It is impossible to accurately judge the occurrence time of the real impact event. Experimental data shows that the false alarm rate of traditional products is as high as 50%
[0006] 2. Poor structural integrity: There is a stress concentration area at the interface formed by two-time glue sealing. Through experiments, when the impact acceleration exceeds 50g, the glue layer is likely to peel off and fail from the tube body; experimental data shows that the qualified rate of traditional products is 60%
[0007] On the other hand, the existing assembly method requires multiple operations of filling glue and sealing, which not only increases the production steps and costs, but also reduces the production efficiency
[0008] To solve the above problems, the present invention proposes a production method and a status display for an item impact status monitoring chip that realizes permanent sealing through a hot melt method Summary of the Invention

[0033] The advantages and technical effects of the present invention: Through the innovative hot melt sealing process and the collaborative design of materials and structures, the present invention achieves significant improvements in sealing reliability, production efficiency, and environmental tolerance. The specific technical effects are as follows:
[0034] I. Product structure optimization
[0035] Integrated Sealing Structure: A seamless closed structure is formed by two - stage hot - melt sealing, completely eliminating the physical interface generated by the traditional adhesive process, avoiding the interface stress concentration problem caused by the difference in thermal expansion of materials, and significantly improving the sealing reliability. Through the capillary diffusion channel design formed by hot - melt, the color - development response speed is greatly improved, ensuring instant feedback for impact events.
[0036] Enhanced Mechanical Properties:
[0037] The hot - melt interface exhibits molecular - level fusion characteristics, and the interface bonding strength is significantly higher than that of the traditional adhesive method, effectively resisting structural failure under high - strength impact loads. The material thermal matching design reduces the interface stress fluctuation caused by temperature changes, significantly improving the sealing stability in high - and low - temperature environments.
[0038] II. Improved Production Efficiency
[0039] Simplified Process Flow: The processes of glue spraying and curing waiting in the traditional process are omitted. The single - piece production cycle is greatly shortened through the rapid hot - melt process, significantly improving the mass - production efficiency. Homogeneous materials are used to standardize the process parameters, reducing the complexity of equipment debugging and improving the compatibility of the production line.
[0040] Automation Adaptation and Upgrade: The precise and controllable characteristics of the hot - melt process are adapted to the high - speed continuous production mode, significantly improving product consistency and reducing manual operation errors. The solvent - free and adhesive - free process characteristics reduce the requirements for production environment control, lowering the comprehensive energy consumption and environmental protection treatment costs.
[0041] III. Enhanced Environmental Tolerance: The integral sealing structure maintains excellent sealing performance in extreme temperature cycling and chemical corrosion environments, significantly extending the product service life.
[0042] In addition, cross - field technology integration: Creatively combines the characteristics of thermoplastic materials, precision welding technology, and color - development function requirements to form an inseparable overall technical solution. Reverse technology breakthrough: Overcomes the technical prejudice that hot - melt at high temperature damages sensitive coatings and splashes colored emulsions in traditional cognition. Through controlling temperature and time, a breakthrough in process compatibility is achieved, solving the long - standing contradiction between sealing reliability and production efficiency in the industry.
[0043] In summary, this method uses materials that can be hot - melt welded and sealed when heated to make the outer color - development tube and the colored agent emulsion containing tube, and uses the hot - melt welding technology to achieve their permanent sealing. This not only improves the sealing performance and reliability of the monitoring chip, but also reduces the production cost and improves the production efficiency, providing a more advanced and reliable solution for the field of item impact, shock, drop, and vibration monitoring.

[0049] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0050] Please refer to Figures 1 to 3 , a production method of an impact state monitoring die of an article, comprising the following steps:
[0051] S1. Select and prepare the outer display tube 1 and the colorant emulsion containing tube 2. The outer display tube and the colorant emulsion containing tube are made of materials that can be hot-melt welded and sealed under heating conditions. A coating 3 that can quickly diffuse and develop color when encountering a colored liquid is sprayed on the inner surface of the outer display tube; for example, a nano-coating containing a fluorescent agent is used. The coating needs to mix and develop color with the liquid through physical diffusion, rather than a chemical reaction. The colorant emulsion (containing pigment particles) can develop color quickly through direct mixing, meeting the requirement of "quick diffusion". The selection of this material fundamentally solves the deficiency of the traditional monitoring die in terms of sealing performance, realizes permanent sealing through hot-melt welding, effectively prevents the leakage of the colorant emulsion, and thus improves the reliability and stability of the monitoring die. Secondly, a coating that can quickly diffuse and develop color when encountering a colored liquid is sprayed on the inner surface of the outer display tube. This design enables the monitoring die to quickly reflect the monitoring state through the color development reaction when subjected to physical events such as impact and vibration, greatly improving the accuracy and timeliness of monitoring.
[0052] S2. Place the colorant emulsion containing tube into the external color developing tube and perform a sealing welding. After the sealing welding, the colorant emulsion containing tube is fixedly arranged in the external color developing tube, one end of which is sealed and connected to the external color developing tube, and the other end is lower than the port of the external color developing tube. A connected colored liquid dispersion cavity is formed between the upper end surface of the colorant emulsion containing tube and the external color developing tube, and a semi-finished product is formed after the sealing welding. This step realizes a firm connection and seal between the two by placing the colorant emulsion containing tube into the external color developing tube and performing a sealing welding. This technical treatment brings about remarkable technical effects: first, the sealed welding ensures that the colorant emulsion containing tube is fixed in the external color developing tube, thus avoiding the problem of sealing failure or inaccurate monitoring caused by loosening during subsequent processing or use; second, the structural design in which one end is sealed and connected to the external color developing tube and the other end is lower than the port of the external color developing tube not only ensures the sealing performance, but also enables the colorant emulsion to flow along a predetermined path when subjected to physical events such as impact and shock, thereby triggering a color development reaction; third, the connected colored liquid dispersion chamber formed between the upper end surface of the colorant emulsion containing tube and the external color developing tube provides sufficient space for the dispersion and color development reaction of the colorant emulsion, further improving the sensitivity and accuracy of monitoring.
[0053] S3, the primary semi-finished product is perfused with a colorant emulsion, and a secondary semi-finished product is formed after perfusion. The colorant emulsion 2-1 can be a red colorant emulsion of the prior art, for example, mainly including a pigment-type scarlet pigment, a dispersant, a wetting agent, a coupling agent, industrial alcohol antifreeze, etc., and an emulsion with a certain viscosity. The emulsion satisfies that when the vibration of the detected object is less than the threshold value of N times the gravitational acceleration, it will not flow out; taking a display with a commonly used specification of 25g (about 245.1m / s2) as an example, if the vibration of the object during transportation or packaging exceeds 25g, the indicator line or display part on the status display will change (such as turning red) to indicate that the object may be damaged; the perfusion of the colorant emulsion is a key step for the monitoring tube core to realize the impact, shock, fall and vibration monitoring functions. By perfusing the colorant emulsion, when the monitoring tube core is subjected to a physical event, the colorant emulsion can flow along a predetermined path and trigger the color development reaction of the external color tube, thereby intuitively reflecting the monitoring state. The secondary semi-finished product formed after the injection of the colorant emulsion lays the foundation for the subsequent secondary sealing welding and the formation of the final product. The successful completion of this step marks the completion of a key link in the production process of the monitoring tube core, which facilitates subsequent processing and assembly.
[0054] S4, the injection end of the secondary semi-finished product is subjected to secondary sealing welding to form an internal seal, and the colorant emulsion containing tube contains a monitoring tube core with a certain amount of colorant emulsion. In this step, the injection end of the secondary semi-finished product is permanently sealed by the secondary sealing welding technology, thereby completing the internal sealing structure of the monitoring tube core.
[0055] Further preferably, step S1 includes: (a) Independently cutting and processing the outer display tube with a functional coating according to the geometric parameters corresponding to the target impact resistance level to form a standardized outer display tube;
[0056] (b) Independently cutting and processing the colorant emulsion containing tube with an outer diameter smaller than that of the outer display tube according to the differential geometric parameters corresponding to the same target impact resistance level to form a supporting standardized colorant emulsion containing tube,
[0057] Wherein: the target impact resistance level includes at least five impact acceleration indexes of 25g, 37g, 50g, 75g and 100g;
[0058] The geometric parameters of the outer display tube include the first tube length L1, the first wall thickness δ1 and the first outer diameter D1;
[0059] The geometric parameters of the colorant emulsion containing tube include the second tube length L2, the second wall thickness δ2 and the second outer diameter D2;
[0060] Wherein: L2 < L1, δ1 > δ2, D1 > D1 to form a clearance fit.
[0061] Specifically, please refer to the following table for product specifications.
[0062]
[0063] Further preferably, the step of the primary sealed welding in step 2 specifically includes:
[0064] S2.1. Place the outer display tube on the first positioning jig 4. The first positioning jig is provided with a positioning post 4-1. The positioning post makes the outer display tube vertically upward, and the height of the positioning post is a preset distance;
[0065] S2.2. Place the colorant emulsion containing tube into the outer display tube. The lower end face of the colorant emulsion containing tube in the outer display tube abuts against the positioning post. At this time, the upper end face of the colorant emulsion containing tube is not lower than the upper end face of the outer display tube;
[0066] S2.3. Then transfer it to the first sealed welding station, turn on the hot melt gun, align the upper end faces of the colorant emulsion containing tube and the outer display tube, and perform sealed welding.
[0067] This primary sealing and welding step achieves a high-quality sealed connection between the colorant emulsion containing tube and the outer color display tube through precise positioning and welding operations. Specifically, the first positioning jig and positioning post are used to ensure that the outer color display tube is vertical and the height is preset accurately, providing a stable reference for the insertion of the colorant emulsion containing tube. Subsequently, the lower end face of the colorant emulsion containing tube abuts against the positioning post, and the upper end face is not lower than the outer color display tube, ensuring the precise relative position between the two. Finally, at the first sealing and welding station, a hot melt gun is used to seal and weld the aligned upper end face, forming a firm and airtight connection. This step not only improves the sealing performance and stability of the monitoring die, but also ensures the accuracy and reliability of subsequent colorant emulsion perfusion, laying a solid foundation for the effective operation of the entire monitoring system.
[0068] During the primary sealing and welding process, precise control of the roasting temperature and time is crucial for achieving effective welding of the quartz transistor substrate. The selection of temperature directly affects the welding quality and product performance: if the temperature is too low, the surface of the quartz transistor cannot be sufficiently softened, making it difficult to form a firm weld and easily leading to seal failure; if the temperature is too high, it may cause material deformation, thermal stress concentration, and even structural damage, affecting the accuracy and stability of the monitoring die. Therefore, precise control of the roasting temperature is the key to ensuring welding strength while avoiding material damage and ensuring the long-term reliable operation of the product. In the present invention, the roasting temperature for the primary sealing and welding is 1200°C - 1800°C, and the roasting time is 2 - 5 seconds. Taking the 25g specification as an example, the roasting temperature is 1600°C and the roasting time is 3 seconds.
[0069] Further preferably, the height of the positioning post is such that after the colorant emulsion containing tube is placed in the outer color display tube, the upper end face of the colorant emulsion containing tube is flush with the upper end face of the outer color display tube. The flush design ensures a flat and gapless welding surface, which is conducive to the uniform distribution of the hot melt material and forms a firm seal. At the same time, it avoids uneven welding or stress concentration caused by height differences, improves the welding strength and sealing performance, and thus ensures the overall performance and reliability of the monitoring die.
[0070] Further preferably, the step of colorant emulsion perfusion in step S3 specifically includes:
[0071] S3.1. Flip the outer color display tube and the colorant emulsion containing tube, which are welded and sealed at one end, by 180 degrees and place them in the first positioning groove 5-1 of the second positioning jig 5;
[0072] S3.2. Transfer the positioned outer color display tube and colorant emulsion containing tube to the colorant perfusion station. When moving to the colorant perfusion station, it is in a normal temperature state; inject the colorant emulsion into it through an injection nozzle, and the colorant emulsion occupies 75% - 85% of the volume of the colorant emulsion containing tube.
[0073] This step ensures the effective perfusion of the colorant emulsion in the monitoring die through an accurate operation process. First, the inner and outer color display tubes sealed by welding at one end are flipped 180 degrees and accurately positioned, providing a stable foundation for subsequent perfusion. Secondly, during the transfer to the colorant perfusion station, the temperature is strictly controlled within the range of 20 - 25 °C at room temperature. This temperature range helps to maintain the fluidity and stability of the colorant emulsion, avoiding adverse effects on the emulsion performance caused by too high or too low temperature. Finally, the colorant emulsion is accurately injected into the inner part through an injection nozzle, and the volume of the colorant emulsion in the colorant emulsion containing tube is controlled to account for 75% - 85%. This not only ensures sufficient colorant dosage to trigger the color reaction but also avoids the risk of space occupation or leakage caused by excessive perfusion. The precise execution of this step plays a crucial role in improving the sensitivity, reliability, and stability of the monitoring die.
[0074] Further preferably, the step of secondary sealing and welding in step S4 specifically includes:
[0075] S4.1. Transfer the secondary semi-finished product with the colorant emulsion after perfusion to the second positioning groove 6-1 of the third positioning fixture 6 on the second sealing and welding station for sealing and welding; the setting of the baking temperature and baking time for secondary sealing and welding is particularly significant. Specifically, the baking temperature is accurately controlled within the range of 1200 °C - 1800 °C. This temperature range is sufficient to soften and fuse the welding material, while avoiding a sudden increase in the internal pressure of the colorant emulsion caused by too high a temperature. At the same time, the baking time is strictly limited to 2 - 5 seconds, ensuring the smooth progress of the welding process and preventing abnormal phenomena caused by too long or too short a time. Taking the 25g specification as an example, the baking temperature is 1600 °C and the baking time is 3 seconds. Through this precise control, the problem of splashing of the colored liquid during the welding process is effectively avoided, ensuring production safety, improving product quality and stability, and laying a solid foundation for the reliable operation of the monitoring die.
[0076] Further preferably, the distance between the other end of the colorant emulsion containing tube and the port of the outer color display tube is 7 - 11 mm, preferably 9 mm. This range can balance the impact resistance and the emulsion dispersion effect. If the distance is too low, the emulsion is prone to excessive concentration during impact; if the distance is too high, the dispersion is poor. This design ensures the stable dispersion of the emulsion in the monitoring die after impact, improving reliability.
[0077] Further preferably, it also includes the steps of transferring the monitoring die to the blanking station, inspection, and packaging. Core detection items: sealing integrity, airtightness detection, structural strength, and function verification; simulated impact-triggered color reaction test (response time ≤ 0.8 s, color diffusion uniformity ≥ 80%); environmental tolerance: high and low temperature cycling (-35 °C to 80 °C, no leakage after 10 cycles).
[0078] Under the same conditions, compare with the core indicators of the prior art, and select 10 samples for comparative tests.
[0079]
[0080] The present invention also provides a status display for monitoring the impact, shock, drop and vibration of an article, including the status display that manufactures the monitoring die by the above production method. This design not only ensures the sensitivity and reliability of the display, and can correctly and truly express whether the article has received an impact, but also significantly reduces resource consumption due to its reusable characteristic, which conforms to the concept of circular economy. Through innovative processes and environmental protection designs, it promotes the green and sustainable development of monitoring technologies.
[0081] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
