Description

Technical Field

[0001] The present application relates to the field of digital products, and in particular to a modified glue, a laptop computer, and a digital product quality inspection method. Background Art

[0002] Glue is often required for connection and / or reinforcement in digital products, such as using glue inside digital products. In this case, since the glue inside is not easy or cannot be directly observed, it is difficult to accurately judge the distribution, thickness and uniformity of the glue by traditional methods after the bonding is completed. However, when the production line is running at high speed, any slight bonding defects (such as bubbles, lack of glue, excessive glue, etc.) will affect the assembly accuracy and overall durability of the components, resulting in increased rework and scrap rates of the products. In addition, most existing evaluation methods are destructive tests, such as cutting, tearing and delamination, which not only destroy the product, but also add additional time and material costs. How to solve the above problems is what technicians in this field need to consider. Summary of the invention

[0003] In order to solve the above problems, the embodiments of the present application provide a quality inspection method for modified glue, a laptop computer, and a digital product.

[0013] Furthermore, the modified glue, laptop computer, and digital product quality inspection method provided in the embodiment of the present application can significantly improve the density of the modified glue while ensuring the fluidity of the modified glue by adding an appropriate amount of barium sulfate, thereby making the density difference between the modified glue and the commonly used plastics in digital products (such as laptop computers), ensuring that the CT imaging obtained by the digital product quality inspection method can clearly show the distribution of the modified glue, thereby improving the quality inspection efficiency.

[0021] Typically, digital products often require the use of glue for connection and / or reinforcement, such as using glue inside digital products. In this case, since the glue inside is not easy or cannot be directly observed, it is difficult to accurately judge the distribution, thickness and uniformity of the glue through traditional methods after the bonding is completed. However, when the production line is running at high speed, any slight bonding defects (such as bubbles, lack of glue, excessive glue, etc.) will affect the assembly accuracy and overall durability of the components, resulting in increased product repair and scrap rates. In addition, existing evaluation methods are mostly destructive tests, such as cutting, tearing and delamination, which not only destroy the product, but also add additional time and material costs.

[0022] Correspondingly, the embodiments of the present application provide a modified glue, a laptop computer, and a digital product quality inspection method. The modified glue includes a first component and a second component, and the first component and the second component are configured to be mixed before the modified glue is used; the first component includes a resin, a diluent, a first toughening agent, and 18% to 26% of barium sulfate by mass; the second component includes an amine curing agent, an accelerator, a second toughening agent, and a diluent. The laptop computer includes a main body and the modified glue. The digital product quality inspection method includes the following steps: applying the modified glue as described in any one of the aforementioned embodiments to a digital product; scanning the digital product using computer tomography technology to obtain a CT image; identifying the modified glue in the CT image, analyzing the distribution position, distribution method, and distribution range of the modified glue in the digital product, and evaluating the quality of the digital product.

[0023] In contrast, in the modified glue provided in the embodiment of the present application, by adding an appropriate amount of barium sulfate, the density of the modified glue can be significantly improved while ensuring the fluidity of the modified glue, so that there is a density difference between the modified glue and the commonly used plastics in digital products (such as laptops), ensuring that the CT imaging obtained by the digital product quality inspection method can clearly show the distribution of the modified glue, thereby improving the quality inspection efficiency. At the same time, barium sulfate, as a non-toxic and harmless additive, will not cause additional pollution to the environment, and meets the requirements of green manufacturing of electronic products.

[0024] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0025] The embodiment of the present application provides a modified glue, which includes a first component and a second component, and the first component and the second component are configured to be mixed before the modified glue is used; The first component includes resin, diluent, first toughening agent and 18% to 25% of barium sulfate by mass ratio; The second component includes an amine curing agent, an accelerator, a second toughening agent and a diluent.

[0026] It can be understood that the modified glue provided in the embodiment of the present application contains a suitable amount of barium sulfate, which can increase the density of the modified glue; at the same time, barium sulfate (BaSO 4 ) has a high X-ray absorption capacity. Adding barium sulfate can effectively enhance the density contrast between glue and plastic materials, thereby generating clearer CT images in subsequent CT scans. It enables inspectors to observe the distribution of glue in real time and accurately evaluate the bonding quality without destroying digital products.

[0027] It is understandable that before the modified glue is put into use, the first component and the second component can be stored separately. When the modified glue needs to be put into use, the first component and the second component can be mixed in a mass ratio of 2:1 and then put into use.

[0028] In this embodiment, the mass percentage of barium sulfate can be 18%, 19%, 20%, 21%, 22%, 23%, 24%, or 25%. Preferably, the mass percentage of barium sulfate can be 22%.

[0029] In one embodiment, the first component includes, by mass percentage, 52% of resin, 15% to 22% of diluent, 18% to 25% of barium sulfate, and 8% of a first toughening agent.

[0030] In one embodiment, in the first component, the resin includes bisphenol A epoxy resin and bisphenol F epoxy resin, the diluent includes phenyl glycidyl ether, and the first toughening agent includes polyurethane modifier. In one embodiment, the second component includes, by mass percentage, 70% of an amine curing agent, 4% of an accelerator, 8% of a second toughening agent, and 18% of a diluent.

[0031] In one embodiment, in the second component, the amine curing agent includes polyethylene polyamine, the accelerator includes phenol, the second toughening agent includes a polyurethane modifier, and the diluent includes dibutyl phthalate.

[0032] In this embodiment, the first component includes, by mass percentage, 45.8% of bisphenol A epoxy resin, 6.2% of bisphenol F epoxy resin, 18% of phenyl glycidyl ether, 22% of barium sulfate, and 8% of polyurethane modification; the second component includes, by mass percentage, 70% of polyethylene polyamine, 4% of phenol, 8% of polyurethane modification, and 18% of dibutyl phthalate.

[0033] In one embodiment, the density of the modified glue is greater than or equal to 2.2 g / cm³.

[0034] In this embodiment, the density of the modified glue is preferably 2.5 g / cm³.

[0035] An embodiment of the present application also provides a laptop computer, which includes a main body and the modified glue as described in any one of the above embodiments.

[0036] The modified glue provided in the embodiment of the present application is mainly used for bonding metal parts and plastic parts in the shell of a laptop computer. During use, it is necessary to first apply the modified glue to the metal part, and then heat and press the metal part and the plastic part to form a firmly bonded structure.

[0037] It can be understood that the modified glue provided in the embodiment of the present application is mainly used for bonding metal parts and plastic parts in laptop computer casings, which solves the problem that industrial CT scanning is not able to obtain scanning results with large contrast between colloid and plastic parts in the quality control of laptop computer casing assembly, lays the foundation for systematic and standardized laptop computer casing assembly quality assessment, and provides the possibility for quantitative evaluation of laptop computer casing dispensing assembly quality.

[0038] It can be understood that the addition of barium sulfate can effectively improve the mechanical properties of the glue, and can effectively improve the compressive strength, shear strength and bonding stability of the modified glue, thereby improving the overall durability and structural strength of the laptop computer using the modified glue.

[0039] It is understandable that barium sulfate can reduce the curing shrinkage of the glue and reduce the stress generated during the bonding process, thereby reducing the risk of deformation or damage of the assembly due to stress. This property of the modified glue is particularly important for precision-processed parts (such as laptops), which helps to achieve a higher-precision assembly effect.

[0040] Further integration Figure 1 As shown, in one embodiment, the present application also provides a digital product quality inspection method, which includes the following steps: Step S1: applying the modified glue to the digital product; Step S2: Scanning the digital product using computer tomography technology to obtain a CT image; Step S3: Identify the modified glue in the CT imaging image, analyze the distribution position, distribution mode and distribution range of the modified glue in the digital product, and evaluate the quality of the digital product.

[0041] As you can understand, the high resolution and three-dimensional imaging capabilities of CT (computed tomography) technology enable it to observe the internal structure of an object from multiple angles and in all directions. Compared with traditional two-dimensional X-ray detection, CT scanning can generate a complete three-dimensional image, thereby more accurately identifying internal defects.

[0042] In one embodiment, plastic is used in the digital product, and the density of the modified glue is adjusted so that the density of the modified glue is greater than the density of the plastic, and the difference between the density of the modified glue and the density of the plastic is at least 1g / cm³.

[0043] Understandable, e.g. Figure 2 As shown, Figure 2 The following are the normal appearance diagrams and CT images of digital products (such as laptops) that do not use modified glue. Figure 2As can be seen in the figure, due to the small difference in density between general glue and plastic materials, the contrast between the two in the CT image is not obvious, resulting in the inability to clearly identify the distribution of glue. Figure 3 As shown, Figure 3 What is shown is a normal appearance schematic diagram and CT imaging diagram of a digital product (such as a laptop computer) using the modified glue provided in the embodiment of the present application. Figure 3 It can be seen that the modified glue provided in the embodiment of the present application contains a suitable amount of barium sulfate, which can increase the density of the modified glue; at the same time, barium sulfate (BaSO 4 ) has a high X-ray absorption capacity. Adding barium sulfate can effectively enhance the density contrast between glue and plastic materials, thereby generating clear images in CT scans. This allows inspectors to observe the distribution of glue in real time and accurately evaluate the bonding quality without damaging digital products.

[0044] In one embodiment, the modified glue and the plastic in the laptop computer case have a certain density difference. When a CT image is obtained using computed tomography technology, the contrast between the modified glue and the plastic in the laptop computer case in the CT image is increased by at least 30%, ensuring clear imaging and being able to effectively identify defects such as bubbles and cracks in the glue.

[0045] It can be understood that the defects that can be observed by the modified glue and digital product quality inspection method provided in the embodiments of the present application include at least three defects: uneven glue distribution, the presence of bubbles or gaps, and excessive or insufficient glue.

[0046] For the defect of uneven glue distribution: CT scanning three-dimensional imaging can identify the thickness change of modified glue at the joints of digital products. Correspondingly, adjustments can be made through observation to ensure that the glue coverage of the entire bonding area is sufficient and uniform.

[0047] Among them, for defects such as bubbles or gaps: CT scanning three-dimensional imaging can clearly show whether there are bubbles or incompletely filled areas in the modified glue, which will affect the strength of the bonding. Correspondingly, bubbles or incompletely filled areas can be detected by observation, and digital products that may have quality problems can be selected.

[0048] Among them, for defects such as excessive or insufficient glue: by presenting the density difference between modified glue and plastic, CT scanning three-dimensional imaging can identify modified glue and determine whether the modified glue is used excessively or insufficiently. Correspondingly, adjustments can be made through observation to avoid problems such as glue overflow or weak bonding.

[0049] It can be understood that the modified glue, laptop computer, and digital product quality inspection method provided in the embodiments of the present application, by adding an appropriate amount of barium sulfate, the density of the modified glue can be significantly improved while ensuring the fluidity of the modified glue, thereby creating a density difference between the modified glue and the commonly used plastics in digital products (such as laptop computers), ensuring that the CT images obtained by the digital product quality inspection method can clearly present the distribution of the modified glue, thereby improving the quality inspection efficiency.

[0050] Furthermore, barium sulfate, as a non-toxic and harmless additive, will not cause additional pollution to the environment and meets the requirements of green manufacturing of electronic products.

[0051] It can be understood that the high chemical stability of barium sulfate prevents it from easily reacting with other substances, does not reduce the chemical stability of the glue, and does not corrode metal or plastic parts. It has excellent properties, which helps to extend the service life of the modified glue and the products using the modified glue while maintaining green environmental protection.

[0052] Furthermore, the production cost of modified glue after adding modifying materials such as barium sulfate can be effectively controlled (for example, the cost increase does not exceed 20% of the original glue), ensuring that the modified glue is economically feasible.

[0053] Embodiment 1: The modified glue includes a first component and a second component; wherein the first component includes, by mass percentage, 52% of resin (45.8% of bisphenol A epoxy resin and 6.2% of bisphenol F epoxy resin), 15% of phenyl glycidyl ether, 25% of barium sulfate, and 8% of polyurethane modifier; wherein the second component includes, by mass percentage, 70% of polyethylene polyamine, 4% of phenol, 8% of polyurethane modifier, and 18% of dibutyl phthalate.

[0054] The first component and the second component are mixed in a mass ratio of 2:1, the mixed modified glue is set at a predetermined position of the digital product, pressed at 60°C for 60 seconds, and then the digital product with the modified glue is CT scanned and a CT image is obtained.

[0055] In Example 1, the CT imaging can show that the contrast between the modified glue and the plastic is high, but the fluidity of the modified glue can be even better, and the spreading degree of the modified glue is somewhat different from that of the ordinary glue.

[0056] Embodiment 2: The modified glue includes a first component and a second component; wherein the first component includes, by mass percentage, 52% of resin (45.8% of bisphenol A epoxy resin and 6.2% of bisphenol F epoxy resin), 22% of phenyl glycidyl ether, 18% of barium sulfate, and 8% of polyurethane modifier; wherein the second component includes, by mass percentage, 70% of polyethylene polyamine, 4% of phenol, 8% of polyurethane modifier, and 18% of dibutyl phthalate.

[0057] The first component and the second component are mixed in a mass ratio of 2:1, the mixed modified glue is set at a predetermined position of the digital product, pressed at 60°C for 60 seconds, and then the digital product with the modified glue is CT scanned and a CT image is obtained.

[0058] In Example 2, the CT imaging can observe that the contrast between the modified glue and the plastic is relatively low, but the modified glue has a strong fluidity, and the spreading degree of the modified glue is somewhat different from that of ordinary glue, and there is a possible risk of glue overflow.

[0059] Embodiment 3: The modified glue includes a first component and a second component; wherein the first component includes, by mass percentage, 52% of resin (45.8% of bisphenol A epoxy resin and 6.2% of bisphenol F epoxy resin), 18% of phenyl glycidyl ether, 22% of barium sulfate, and 8% of polyurethane modifier; wherein the second component includes, by mass percentage, 70% of polyethylene polyamine, 4% of phenol, 8% of polyurethane modifier, and 18% of dibutyl phthalate.

[0060] The first component and the second component are mixed in a mass ratio of 2:1, the mixed modified glue is set at a predetermined position of the digital product, pressed at 60°C for 60 seconds, and then the digital product with the modified glue is CT scanned and a CT image is obtained.

[0061] In Example 3, the CT imaging image shows that the contrast between the modified glue and the plastic is moderate, and the spread modified glue and the plastic components can be clearly distinguished in the CT imaging image; at the same time, the fluidity of the modified glue is moderate, which can more accurately reflect the spreading status of the modified colloid.

[0062] It can be seen from Examples 1 to 3 that adding barium sulfate to the modified glue can have a significant effect on the density and fluidity of the modified glue. When its components correspond to 18% phenyl glycidyl ether and 22% barium sulfate, the density and fluidity of the modified glue are relatively moderate.

[0063] In the above, the specific embodiments of the present application are described with reference to the accompanying drawings. However, those skilled in the art will appreciate that various changes and substitutions may be made to the specific embodiments of the present application without departing from the scope of the present application. These changes and substitutions are all within the scope defined by the present application.
