[0002] The use of adhesives is unavoidable in laser production lines. The internal components of lasers and optical elements have relatively stringent requirements for the working environment, including cleanliness, humidity, temperature, material combustion efficiency, heat dissipation, and volatility. Since lasers and optical elements rely on adhesives, improving the overall performance of these adhesives requires comparison with existing adhesives, making volatility testing an essential step. Current technology for testing adhesive volatility cannot simulate the working environment of lasers or optical elements, and therefore cannot quantitatively detect or compare adhesive volatility. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an adhesive volatility testing device and method, which solves the problem that existing adhesive volatility testing devices cannot relatively quantitatively detect or compare the volatility of adhesives.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An adhesive volatility testing device includes a laser output component, a lens assembly, a test plate, a power meter, and an outer casing. The laser output component includes an output optical fiber connected to a laser generator for outputting laser light. The lens assembly includes a rotating disk and a transparent lens.

The area of ​​the outer casing corresponding to the laser projection is made of transparent material. Limiting plates are selectively provided inside the outer casing. The configuration of the limiting plates is adapted to the application scenario of the laser or optical element.

[0032] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0033] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0034] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "rear," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly. For example, Figure 1-7 In the relative positions shown, the test board 30 is horizontally positioned at the bottom, while the fiber optic mounting bracket 10, outer cover 5, and power meter bracket 40 can be vertically or perpendicular to the test board. In this context, directional terms such as "horizontal" and "vertical" are used only for convenience in describing the positional relationships in the attached diagram and do not impose any specific directional restrictions.

[0035] Unless otherwise specified, the experimental methods described in the following examples are conventional methods; the reagents and materials described are commercially available unless otherwise specified.

[0036] The endpoints and any values ​​disclosed in this invention are not limited to the precise range or value, and such ranges or values ​​should be understood to include values ​​close to such ranges or values. For numerical ranges, the endpoint values ​​of the various ranges, the endpoint values ​​of the various ranges and individual point values, and individual point values ​​can be combined with each other to obtain one or more new numerical ranges, which should be considered as specifically disclosed herein.

[0037] Please refer to Figure 1-8As shown, this invention provides an adhesive volatility testing device 100, including a laser output assembly 1, a lens assembly 2, a test plate assembly 3, a data acquisition device 4, and an outer casing 5. The laser output assembly 1, lens assembly 2, data acquisition device 4, and outer casing 5 can be all or partially mounted on the test plate assembly 3. The test plate assembly 3 includes a test plate 30, on which a sample detection (carrying) area 31 is provided for carrying and heating the adhesive to be tested. The lens assembly 2 and the sample detection area 31 are located inside the outer casing 5, while the laser output assembly 1 and the data acquisition device 4 are located outside the outer casing 5. The outer casing 5 includes a movable door 51, which can be closed or opened. When the movable door 51 is closed, a sealed space is formed inside the outer casing 5, which is used to simulate the internal environment of a laser and the application scenarios of optical components.

[0038] Combined with reference Figure 1-3 The laser output assembly 1 includes a fiber optic mounting bracket 10 and an output fiber 12 mounted on its top. The output fiber 12 is connected to a laser generator 11 and is used to output laser light for testing. The height of the fiber optic mounting bracket 10 can be adjusted by raising and lowering it to adjust the height of the output fiber 12, or by rotating it to adjust the angle at which the output fiber 12 is aligned with the lens 21. It can also be moved as a whole to adjust the distance between the fiber optic mounting bracket 10 and the lens 21. In some specific embodiments, the bottom of the fiber optic mounting bracket 10 is movably and adjustablely mounted on the test plate 30. Specifically, one or more mounting holes (e.g., screw holes) can be provided on one side of the test plate 30 corresponding to the laser output assembly 1 to move the fiber optic mounting bracket 10 away from or towards the lens 21. Fasteners such as screws can be used to fix the bottom of the fiber optic mounting bracket 10 to the mounting holes at different positions to adjust the distance between the fiber optic mounting bracket 10 and the lens 21. In a specific example, the fiber optic mounting bracket 10 includes a top platform 13, a telescopic rod, and a base 16. The telescopic rod includes an upper rod 14 and a lower rod 15. The platform 13 is connected to the top of the upper rod 14 and can be fixedly connected. The base 16 is connected to the bottom of the lower rod 14 and can be fixedly connected. The base 16 is mounted on the test plate 30. The upper rod 14 can rotate and extend relative to the lower rod 15. The upper rod 14 and the lower rod 15 are circular tubes that are nested together. For example, the upper rod 14 is thinner and can be telescopically stored inside the lower rod 15. The upper rod 14 and the lower rod 15 have multiple through holes along their respective lengths. Fasteners such as thumbscrews 17 are inserted into the through holes to fix the upper rod 14 and the lower rod 15 at different positions of their total length, thereby achieving rotational adjustment, vertical adjustment, and relative fixation. The platform 13 is provided with fiber optic slots, such as U-shaped slots. The output fiber optic cable 12 is placed in the U-shaped slot and can be fixed with high-temperature resistant tape. The power of the laser generator 11 is an indicator of the amount of adhesive evaporated.

[0039] Combined with reference Figure 1-2 and Figure 4-5The lens assembly 2 includes a rotating disk 20, a back plate 23, and a transparent lens 21. The lens 21 is transparent glass or other transparent crystal. The rotating disk 20 is used to position the lens 21 at a predetermined distance above the sample detection area 31. The rotating disk 20 is rotatably and adjustablely mounted on the back plate 23, and its height can be adjusted along the perforations 27 provided on the back plate 23. Figure 2 The two lens assemblies 2 shown are at their vertical adjustment limits, thereby adjusting the angle of the lens 21 and the distance between the lens 21 and the sample detection area 31. In a specific example, the rotating disk 20 can be designed as a knob, with a slot 24 for mounting the lens 21. The slot 24 can be a through groove along (but not limited to) the diameter direction. The lens 21 is inserted into the slot 24, and both ends are secured by fasteners (such as screws) 25 in conjunction with the mounting holes on the edge of the rotating disk 20 to prevent the lens 21 from moving. The rotating disk 20 is also provided with an arc-shaped slide groove 26. Fasteners (such as screws) 28 are inserted from the drain hole 27 on the back plate 23 and into the arc-shaped slide groove 26 of the rotating disk 20. Loosening the fasteners 28 allows the rotating disk 20 to be rotated and adjusted, while tightening the fasteners 28 fixes the rotating disk 20 at the corresponding angle position.

[0040] For example, the holes 27 are arranged in two rows, vertically on the back plate 23, so that the rotating disk 20 can be moved up and down vertically, thereby adjusting the height of the adjusting lens 21 relative to the base plate 30 (or the sample detection area 31). The back plate 23 can be the vertical inner wall of the outer cover, or a separately provided independent back plate, such as... Figure 4 The L-shaped plate shown has its bottom bend secured by the bottom edge of the outer cover 5 and the test plate 30. The rotating disk 20 can be rotatably mounted on the back plate 23, or it can be moved up and down through the row holes 27 and then fixed by the fasteners 28. The up and down movement can control the distance between the glue and the lens 21, thereby controlling the amount of glue evaporating onto the lens 21. Depending on the application scenario within the laser, multiple sets of lens assemblies 2 can be set up to detect the amount of glue evaporating at different locations. In this case, the multiple lenses 21 that have adsorbed glue evaporating can be adjusted to the projection direction of the output laser of the fiber optic 12 for detection; or, a set of lens assemblies 2 can be set up, the lenses 21 can be adjusted to different positions to adsorb glue evaporating, and then adjusted to the projection direction of the output laser for detection. In this case, multiple back plates 23 or multiple rows of row holes can be set up.

[0041] Combined with reference Figure 1-2 and Figure 6-7The test plate assembly 3 includes a test plate 30, on which a sample detection area 31 is provided. The test plate has an annular water channel 32, an inlet, and an outlet. The annular water channel 32 contains a heating medium such as water or oil and is connected to an external heating device, such as a mold temperature controller 33, through the inlet and outlet to circulate heating water or oil to heat the sample detection area 31. The annular water channel 32 surrounds the sample detection area 31, which can be (but is not limited to) a groove, with the annular water channel 32 surrounding the groove. The functions of the test plate 30 include: 1) carrying the adhesive to be tested; 2) circulating a heating medium, such as hot water or hot oil, to heat the adhesive; and 3) mounting components such as the fiber optic mounting bracket 10, the lens assembly 2 (specifically the back plate 23), the power meter bracket 40, and the outer cover 5. The test plate 30 can be made of thermally conductive materials such as aluminum or copper to simulate the application scenarios of aluminum and copper substrates inside lasers. Different materials are selected for different applications; different materials have different thermal conductivity and heat capacity, which also affect the adhesive differently. The adhesive to be tested is placed in the groove of the test plate 30, i.e., the sample detection area 31; the water channel 32 is designed as an annular water channel to make the adhesive heat more thoroughly, accelerate evaporation, reduce experimental time, and speed up the experimental conclusion.

[0042] Combined with reference Figure 1-2 and Figure 8The acquisition device 4 includes a power meter bracket 40 and a power meter 41 on top of the bracket. The function of the power meter 41 is to receive the laser power to parameterize and compare the amount of evaporation. The amount of glue evaporation is inversely proportional to the power displayed on the power meter. Multiple power meters can be used; a suitable power meter can be selected for different types of glue to broaden the parameter range and increase the comparison volume. The power meter 41 is mounted on top of the power meter bracket 40 and can be adjusted vertically or rotated. In a specific example, the power meter bracket 40 is designed as a telescopic rod, including an upper rod 42, a lower rod 43, and a base 44. The power meter is connected to the top of the upper rod 42 and can be fixedly connected. The upper rod 42 can rotate and extend relative to the lower rod 43. The upper rod 42 and lower rod 43 are circular tubular and interlocked. For example, if the upper rod 42 is thinner, it can be retracted into the lower rod 43. Multiple through holes are provided along the length of the upper rod 42 and lower rod 43. Fasteners such as thumbscrews 45 are inserted into these through holes to fix the upper rod 42 and lower rod 43 at different positions relative to each other, thus achieving rotational adjustment, vertical adjustment, and relative fixation. The rotation angle of the power meter 41 can be used to control the amount of absorbed laser light, thereby determining the amount of glue evaporation. The base 44 is movable and adjustable on the test plate 30. The preferred position of the power meter 41 is perpendicular to the projection direction of the output laser light from the output fiber 12. By providing one or more mounting holes (e.g., screw holes) on one side of the test plate 30 corresponding to the acquisition device 4, and by providing mounting holes on the base of the bracket 40, the acquisition device 4 is moved, and fasteners such as screws are used to engage with the mounting holes to fix the base 43 of the acquisition device 4 to the mounting holes at different positions on the test plate 30, thereby adjusting the distance between the acquisition device 4 (i.e., the power meter 41) and the lens 21. The power meter 41 is connected to a computer or display device 46 to display the power meter's information. Of course, a power meter with direct reading can also be used, which would eliminate the need for a display device or computer.

[0043] The outer casing 5 serves several purposes: 1) to provide a sealed isolation, preventing external factors from affecting the experimental results; 2) to compress the space, simulating a real-world environment to accurately reflect the evaporation phenomenon inside the laser; and 3) to protect personnel safety, preventing burns from splashing in high-temperature environments. The outer casing's door 51 can move up and down, for example, designed as a roller shutter door 51, controlled by a switch to open and close, facilitating operation. The area corresponding to the laser projection on the outer casing 5 is made of a transparent material, such as transparent glass. For example, the laser output component 1 and the acquisition device 4 are respectively installed on the left and right sides of the test plate 30, and the left and right sidewalls of the outer casing are made of transparent material. The laser output from the fiber optic cable 12 passes through the left side wall of the outer casing 5, enters the outer casing 5, is transmitted to the lens 21, is then transmitted through the right side wall of the outer casing 5, and is transmitted to the power meter 41. The door 51 can be made of a non-transparent or transparent material.

[0044] Based on the simulated laser application scenario by the testing equipment, a limiting plate 6 can be selectively installed inside the outer casing 5. The configuration of the limiting plate 6 corresponds to the simulated application scenario. In the example shown in the figure, the limiting plate 6 is installed parallel to the test plate at a predetermined height, dividing the interior of the outer casing 5 into upper and lower parts. A set of lens assemblies 2 can be installed in each of the upper and lower parts, or only one set of lens assemblies 2 can be installed. The height difference of the limiting plate 6 can be adjusted to compress the space size, simulating the evaporation of adhesive in a real-world scenario, thus realistically replicating the application scenario.

[0045] The working principle of the testing equipment of this invention is as follows: The adhesive to be tested is placed in the groove of the test plate, i.e., the test area 31. The test plate is heated by a heating device (e.g., a water chiller / mold temperature controller) 32 to heat the medium in the annular water channel 32 to heat the adhesive to a predetermined temperature, causing the adhesive to evaporate. The lens 21 is coated with adhesive volatiles. The laser generator outputs laser light through the optical fiber 12, which is transmitted through the transparent glass cover to the transparent lens 21. Part of the laser light passes through the lens 21 and is projected onto the power meter 41 of the acquisition device 4 behind it; some of the laser light is absorbed by the adhesive volatiles. The power parameters on the power meter 41 can be collected by a computer or display 46. Multiple adhesive samples are tested, and the test results are combined to compare the evaporation amount of different adhesives. The evaporation amount of adhesive is inversely proportional to the power displayed on the power meter. The distance between the lens 21 and the adhesive can be adjusted by moving the lens rotating disk 20 up and down. The closer the lens 21 is to the adhesive, the more adhesive volatiles will be emitted from the lens 21. The angle of the lens 21 can also be adjusted by rotating the rotating disk 20. The more parallel the test area 31 of the adhesive on the lens 21 is, the greater the amount of adhesive evaporation received. For adhesives with low evaporation or low volatility, the evaporation rate can be increased by raising the contact temperature between the adhesive and the test plate, i.e., increasing the temperature of the heating medium in the annular channel. This can be achieved by setting the output temperature of the mold temperature controller. The space size can be compressed by adjusting the height difference of the limiting plate 6 to simulate the adhesive evaporation situation in a real-world scenario, realistically replicating the application scenario.

[0046] The method for testing the volatility of adhesives includes the following steps:

[0047] Step 1: Provide the adhesive volatility testing device 100 of the above embodiments;

[0048] Step 2: Adjust the positions of optical fiber 12, lens 21, and power meter 41, and set the output temperature of heating device 33;

[0049] Step 3: Place the adhesive to be tested into the groove of the test area 31, start the heating equipment to the predetermined temperature and heating time to allow the adhesive to evaporate, and the lens 21 will be covered with adhesive volatiles.

[0050] Step 4: Adjust the lens 21 with the adsorbed glue volatiles to the projection direction of the output laser of the fiber optic 12, start the laser generator 11, and output the laser from the fiber optic 12 to the lens 21 and then transmit it to the power meter.

[0051] Step 5: Read the power value of power meter 41 to obtain the parameterized index of the volatility of the adhesive to be tested, and record the test conditions at the same time.

[0052] When comparing the volatility of various adhesives, repeat the above steps with multiple adhesive samples to obtain the volatility parameters of the comparison adhesive samples. Based on the detected parameters, the comparison results of the volatility of different adhesives can be obtained, and the appropriate adhesive can be selected based on the comparison results.

[0053] To test the effect of adhesive volatiles in different locations or scenarios, the lens 21 can be adjusted to different locations or scenarios, and the limiting plate 6 can be set in conjunction with it; or, the lens 21 can be configured in different locations or scenarios, and the limiting plate 6 can be set in conjunction with it. Following the above detection steps, the lens with adhesive volatiles can be adjusted to the projection direction of the output laser of the fiber optic 12 for power detection, thereby quantitatively detecting the environment in different locations or scenarios.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
