[0038] Next, refer to Figures 1-7 Describe the foaming adhesive spline preparation device 100 according to the embodiments of the present utility model.
[0039] As Figure 1 and Figure 2As shown, a foaming adhesive spline preparation device 100 according to an embodiment of the present utility model includes a substrate 1, a lower body 2, a fixed insert 3, a movable insert 4, and an upper body 5.
[0040] Specifically, as Figure 1 and Figure 2 shown, the lower body 2 is disposed above the substrate 1 and connected to the substrate 1. The lower body 2 is provided with an installation space 21. The installation space 21 penetrates the lower body 2 in the up and down direction (such as the up and down direction shown in Figure 2 ). Other components in the foaming adhesive spline preparation device 100 can be installed in the installation space 21. The lower body 2 can protect the multiple components in the installation space 21, avoid external force impact on other components in the installation space 21, and increase the strength of the foaming adhesive spline preparation device 100.
[0041] As Figure 2 , Figure 4 and Figure 5 shown, the fixed insert 3 is disposed in the installation space 21 and fixedly connected to the substrate 1. The fixed insert 3 can penetrate into the installation space 21 after being fixedly connected to the substrate 1, increasing the reliability of the assembly of the fixed insert 3. The upper surface of the fixed insert 3 is lower than the upper surface of the lower body 2, and the upper surface of the fixed insert 3 serves as the lower forming surface of the foaming adhesive spline.
[0042] The movable insert 4 is movably disposed in the installation space 21 in the up and down direction. The movable insert 4 surrounds the fixed insert 3, and the side wall of the movable insert 4 close to the fixed insert 3 serves as the side forming surface of the foaming adhesive spline.
[0043] In the prior art, the foaming adhesive is sprayed onto a flat plate and scraped flat. After foaming and curing, a flat plate sample is formed. Then, a spline is cut out from the flat plate sample by a cutting method, and then performance testing is carried out. After the foaming adhesive foams, since the foaming ratio at each position cannot be exactly the same, the thickness of the spline is uneven, and the dispersion of the test results is large. Moreover, the foamed adhesive becomes hard and brittle. When the foamed flat plate sample is cut into a spline by a punching method, the punching edge is relatively rough, and some foaming holes are prone to defects such as chipping, resulting in stress concentration at the defective part and large errors in the test results.
[0044] As Figure 6 shown, the upper body 5 is movably disposed above the lower body 2 in the up and down direction. The lower surface of the upper body 5, the upper surface of the fixed insert 3, and the movable insert 4 jointly define a preparation space 31 for the foaming adhesive spline. The lower surface of the upper body 5 serves as the upper forming surface of the foaming adhesive spline. The upper body 5 is provided with a nozzle 51 for injecting glue into the preparation space 31.
[0045] It can be understood that during the preparation process of the foaming adhesive spline, the upper body 5 cooperates with the lower body 2. The lower surface of the upper body 5, the upper surface of the fixed insert 3, and the movable insert 4 jointly define the preparation space 31 for the foaming adhesive spline. Glue is poured into the preparation space 31 through the pouring nozzle 51 on the upper body 5. After the glue pouring process in the preparation space 31 is completed, the upper body 5 moves upward, and the movable insert 4 moves upward. The upper surface of the movable insert 4 always fits with the lower surface of the upper body 5. The lower surface of the upper body 5, the upper surface of the fixed insert 3, and the movable insert 4 jointly define the foaming space for the foaming adhesive spline, realizing the foaming of the foaming adhesive and the preparation of the spline.
[0046] The thickness of the foaming adhesive spline prepared by the foaming adhesive spline preparation device 100 is relatively uniform, and the preparation space 31 and the foaming space can be directly defined in the shape required for performance testing. The prepared foaming adhesive spline does not need to be processed again, avoiding defects at the edges of the foaming adhesive spline and stress concentration at the edges of the foaming adhesive spline, increasing the reliability of the performance test results.
[0047] According to the foaming adhesive spline preparation device 100 of the embodiment of the present invention, by providing the pouring nozzle 51 on the upper body 5, the lower surface of the upper body 5, the upper surface of the fixed insert 3, and the movable insert 4 jointly define the preparation space 31 for the foaming adhesive spline. During the preparation process of the foaming adhesive spline, the upper body 5 cooperates with the lower body 2, and glue is poured into the preparation space 31 through the pouring nozzle 51 on the upper body 5. After the glue pouring process in the preparation space 31 is completed, the upper body 5 and the movable insert 4 move upward, realizing the foaming of the foaming adhesive and the preparation of the spline. The thickness of the prepared foaming adhesive spline is relatively uniform, and the preparation space 31 can be directly defined in the shape required for performance testing. The prepared foaming adhesive spline does not need to be processed again, avoiding defects at the edges of the foaming adhesive spline and stress concentration at the edges of the foaming adhesive spline, increasing the reliability of the performance test results.
[0048] In this embodiment, as Figure 4 and Figure 5 shown, the fixed insert 3 is provided with a boss 32, and the base plate 1 is provided with a corresponding mating hole 11. The boss 32 passes through the mating hole 11, and the connection between the fixed insert 3 and the base plate 1 is relatively simple and reliable.
[0049] In this embodiment, the lower body 2 and the base plate 1 are connected by fasteners, and the connection between the lower body 2 and the base plate 1 is relatively simple and reliable.
[0050] In some embodiments of the present invention, as Figure 1As shown, a distance adjustment structure 6 is provided between the upper body 5 and the lower body 2, and the distance adjustment structure 6 is used to adjust the distance between the upper body 5 and the lower body 2 in the up and down directions, so that the distance adjustment between the upper body 5 and the lower body 2 in the up and down directions can be more reliable, and the lower surface of the upper body 5, the upper surface of the fixed insert 3 and the movable insert 4 can jointly define the foaming space of the foaming adhesive strip, so that the preparation process of the foaming adhesive strip is more reliable.
[0051] Furthermore, the distance-adjusting structure 6 is a distance-adjusting bolt, which can accurately adjust the gap between the upper body 5 and the lower body 2, and the distance-adjusting bolt is easy to install and disassemble, which can save a lot of installation and maintenance time.
[0052] In some embodiments of the present invention, Figure 1 As shown, the side wall of the lower body 2 is installed with an upwardly extending scale 7, which is used to indicate the distance between the upper body 5 and the lower body 2 in the up and down directions, so as to facilitate the observation of the distance between the upper body 5 and the lower body 2 in the up and down directions, thereby limiting the foaming size of the foamed adhesive strip, and making the size of the prepared foamed adhesive strip more reliable.
[0053] In some embodiments of the present invention, Figure 7 As shown, a pouring port 22 is provided at a position corresponding to the pouring nozzle 51 of the lower body 2, and a first flow channel 41 is provided on the upper surface of the movable insert 4, and the first flow channel 41 connects the pouring port 22 and the preparation space 31. It can be understood that during the preparation of the foaming adhesive strip, the upper body 5 cooperates with the lower body 2, and the lower surface of the upper body 5, the upper surface of the fixed insert 3 and the movable insert 4 jointly define the preparation space 31 of the foaming adhesive strip, and the glue is poured into the preparation space 31 through the pouring nozzle 51 on the upper body 5, and the foaming adhesive enters the preparation space 31 from the pouring port 22 through the first flow channel 41.
[0054] After the glue filling process in the preparation space 31 is completed, the upper body 5 moves upward, and the movable insert 4 moves upward, which can cut off the connection between the preparation space 31 and the filling nozzle 51, so as to prevent the foamable adhesive from flowing back into the filling nozzle 51 when the foamable adhesive is foaming, and to prevent the filling nozzle 51 from being blocked. The upper surface of the movable insert 4 is always in contact with the lower surface of the upper body 5, and the lower surface of the upper body 5, the upper surface of the fixed insert 3 and the movable insert 4 jointly define the foaming space of the foamable adhesive strip, so as to realize the foaming of the foamable adhesive and the preparation of the strip.
[0055] In some embodiments of the present invention, Figure 7 As shown, a second flow channel 23 is defined between the pouring port 22 of the lower body 2 and the first flow channel 41 , and the filling nozzle 51 , the pouring port 22 , the second flow channel 23 and the first flow channel 41 jointly define a flow path for the foamable adhesive, facilitating the foamable adhesive to flow into the preparation space 31 .
[0056] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, a guiding post 24 is provided on the upper surface of the lower body 2, and a guiding hole 52 that mates with the guiding post 24 is provided on the upper body 5. The upper body 5 can move in the up-and-down direction under the cooperation of the guiding post 24 and the guiding hole 52, and the movement of the upper body 5 in the up-and-down direction is relatively reliable.
[0057] In this embodiment, the cooperation between the guiding post 24 and the guiding hole 52 is relatively tight, and the clearance between the guiding post 24 and the guiding hole 52 is less than 0.05 mm, making the movement of the upper body 5 in the up-and-down direction relatively reliable.
[0058] In some embodiments of the present utility model, as Figure 1 and Figure 3 shown, the foaming adhesive spline preparation device 100 further includes a handle 8, and the handle 8 is fixedly connected to the upper surface of the upper body 5. By providing the handle 8, the upper body 5 can be lifted more conveniently, and the handle 8 can more conveniently adjust the distance between the upper body 5 and the lower body 2 in the up-and-down direction.
[0059] In some embodiments of the present utility model, in the up-and-down direction, the distance L between the upper surface of the fixed insert 3 and the upper surface of the lower body 2 is 1 - 3 mm. It can be understood that in the up-and-down direction, the distance L between the upper surface of the fixed insert 3 and the upper surface of the lower body 2 can be 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm or 3 mm. In the up-and-down direction, the distance L between the upper surface of the fixed insert 3 and the upper surface of the lower body 2 is not less than 1 mm, which can ensure the size of the preparation space 31 for the foaming adhesive spline and increase the original size of the foaming adhesive; in the up-and-down direction, the distance L between the upper surface of the fixed insert 3 and the upper surface of the lower body 2 is not greater than 3 mm, which can avoid the original size of the foaming adhesive from being too large, and can avoid the need for a relatively large foaming size for the foaming adhesive, meeting the injection size of the foaming adhesive in practical applications.
[0060] In some embodiments of the present utility model, the upper end of the outer peripheral wall of the movable insert 4 inclines outward and the included angle with the vertical direction is 3 - 7°. The inner wall surface of the installation space 21 is an inclined surface that fits the outer peripheral wall of the movable insert 4. It can be understood that the included angle between the outer peripheral wall of the movable insert 4 and the vertical direction can be 3°, 3.2°, 3.4°, 3.6°, 3.8°, 4°, 4.2°, 4.4°, 4.6°, 4.8°, 5°, 5.2°, 5.4°, 5.6°, 5.8°, 6°, 6.2°, 6.4°, 6.6°, 6.8° or 7°. The included angle between the outer peripheral wall of the movable insert 4 and the vertical direction is not less than 3°, which can avoid large friction between the movable insert 4 and the lower body 2 when the movable insert 4 moves up and down, and can make the telescopic movement of the movable insert 4 smoother; the included angle between the outer peripheral wall of the movable insert 4 and the vertical direction is not greater than 7°, which can reduce the processing amount of the lower body 2 and the movable insert 4, making the processing of the lower body 2 and the movable insert 4 simpler and more convenient.
[0061] In some embodiments of the present utility model, the mating distance between the inner peripheral wall of the movable insert 4 and the outer peripheral wall of the fixed insert 3 in the vertical direction is 5 - 8 mm. It can reduce the mating distance while ensuring the mating effect and the foaming space. And there is a clearance space between the inner peripheral wall of the movable insert 4 and the outer peripheral wall of the fixed insert 3 below the mating distance. The size of the clearance space is 0.2 - 0.5 mm, which can avoid large friction between the movable insert 4 and the fixed insert 3 when the movable insert 4 moves up and down, and can make the telescopic movement of the movable insert 4 smoother.
[0062] In some embodiments of the present utility model, as Figure 2 and Figure 7 shown, the outer peripheral wall of the movable insert 4 has a handle groove 42, and the upper end of the handle groove 42 is open. It is convenient to install the movable insert 4 into the installation space 21 or take out the movable insert 4 from the installation space 21, and the installation and disassembly process of the movable insert 4 is relatively convenient.
[0063] In some embodiments of the present utility model, as Figure 5As shown, the foaming adhesive spline preparation device 100 further includes an elastic member 9. The elastic member 9 is disposed between the movable insert 4 and the substrate 1 and is used to drive the movable insert 4 to move upward. It can be understood that during the preparation process of the foaming adhesive spline, the upper body 5 cooperates with the lower body 2. The lower surface of the upper body 5 presses the movable insert 4 to move downward, and the elastic member 9 is compressed. The lower surface of the upper body 5, the upper surface of the fixed insert 3, and the movable insert 4 jointly define the preparation space 31 for the foaming adhesive spline. Glue is poured into the preparation space 31 through the nozzle 51 on the upper body 5. After the glue pouring process in the preparation space 31 is completed, the upper body 5 moves upward, and the movable insert 4 moves upward under the drive of the elastic member 9, so as to ensure that the upper surface of the movable insert 4 always fits the lower surface of the upper body 5. The lower surface of the upper body 5, the upper surface of the fixed insert 3, and the movable insert 4 jointly define the foaming space of the foaming adhesive spline, realizing the foaming of the foaming adhesive and the preparation of the spline.
[0064] The elastic member 9 can make the movement of the movable insert 4 relatively simple and reliable, facilitating the formation of the preparation space 31 and the foaming space.
[0065] In this embodiment, the elastic member 9 is a spring, and the structure of the elastic member 9 is relatively simple.
[0066] In some embodiments of the present invention, the lower surface of the upper body 5, the upper surface of the fixed insert 3, and the inner side surface of the movable insert 4 are all subjected to surface Teflon treatment. It can be understood that the lower surface of the upper body 5, the upper surface of the fixed insert 3, and the inner side surface of the movable insert 4 all come into contact with the foaming adhesive. The friction coefficient of Teflon is relatively low. After the Teflon treatment, it can be avoided that the lower surface of the upper body 5, the upper surface of the fixed insert 3, and the inner side surface of the movable insert 4 adhere to the foaming adhesive, facilitating the removal of the spline after the preparation is completed.
[0067] In some embodiments of the present invention, the upper body 5, the lower body 2, the movable insert 4, and the fixed insert 3 are all aluminum alloy parts. The upper body 5, the lower body 2, the movable insert 4, and the fixed insert 3 are light in weight and good in strength. While ensuring the strength of the foaming adhesive spline preparation device 100, it is convenient to move the upper body 5, facilitating the foaming of the foaming adhesive.
[0068] In some embodiments of the present invention, the lower surface of the upper body 5 is formed by grinding, which can make the surface flatness of the lower surface of the upper body 5 less than 0.03 mm, ensuring the flatness of the spline.
[0069] Other components and operations of the foaming adhesive spline preparation device 100 according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail here.
