Description

Technical Field

[0001] The present invention relates to the technical field of adhesive bonding strength detection, in particular to a device for detecting the bonding strength of an adhesive for dental fluorosis veneers. Background Art

[0002] Fluoride veneer adhesive is a specialized bonding material used to secure veneers to fluorosis-affected surfaces. Before curing, fluorosis veneer adhesive is typically a viscous liquid or paste-like substance. It possesses a certain degree of fluidity, yet is not too thin. This ensures even distribution upon application to the tooth and veneer surface, preventing it from running, allowing for precise application and adjustment during clinical practice.

[0003] During the production process of fluorosis veneer adhesives, their performance needs to be tested, and the bonding strength of the adhesive is an important test item. Existing fluorosis veneer adhesive bonding strength testing devices usually do not have the function of accelerating the curing rate of the fluorosis veneer adhesive applied to the bonding area during the bonding strength test. The natural curing of the fluorosis veneer adhesive will affect the testing efficiency. Moreover, after the bonding strength test is completed, the fluorosis veneer adhesive cured at the bonding area cannot be softened, making it inconvenient to remove the fluorosis veneer adhesive cured on the test plate.

[0024] In this embodiment, when the adhesive bond strength of a fluorosis veneer adhesive is tested, the adhesive is applied to the upper surface of test block 2 11. The lifting mechanism then drives test block 1 6 downward, bringing the lower surface of test block 1 6 into contact with the adhesive. To accelerate the curing efficiency of the adhesive, electric push rod 2 10 drives connecting bent plate 7 downward, aligning the multiple LED curing lights 81 within square ring plate 8 with the gap between test block 1 6 and test block 2 11. The LED curing lights 81 illuminate the adhesive in the gap, increasing the curing rate and facilitating rapid bond strength testing. After the subsequent bonding strength test is completed, in order to facilitate the rapid cleaning of the adhesive from the test block 1 6 and the test block 2 11, the electric push rod 2 10 is used to drive the connecting bent plate 7 to rise, so that the multiple air outlet holes 91 opened inside the square hollow ring plate 9 are aligned with the fitting gap between the test block 1 6 and the test block 2 11. The hot air mechanism 13 can be used to heat the adhesive at the fitting gap with hot air to soften the adhesive at the bonding position, making it easier to remove the adhesive from the test block.

[0025] Example 2 like Figure 1-7 As shown, on the basis of Example 1, the present invention provides a technical solution. Preferably, the hot air mechanism 13 includes a heating chamber 134 opened inside the base 12, and the interior of the heating chamber 134 is fixedly connected to an electric heating pipe 135. The right end of the heating chamber 134 is provided with a mounting opening 1, and the interior of the mounting opening 1 is fixedly connected to an air duct 136, and the interior of the air duct 136 is fixedly connected to a blowing fan 137.

The upper end of the heating chamber 134 is provided with a mounting opening 2, and the interior of the mounting opening 2 is fixedly connected to an air duct 2 133. The interior of the air duct 2 133 is provided with an air duct 131, and the lower end surface of the air duct 131 is fixedly sleeved with a sealing ring 132. The upper end of the air duct 131 passes through the square hollow ring plate 9 and is fixedly connected to the passing portion.

[0026] In this embodiment, when hot air needs to be input into the interior of the square hollow ring plate 9, by starting the blowing fan 137 and the electric heating tube 135, the electric heating tube 135 can heat the air, and the blowing fan 137 can allow the heated air to be input into the interior of the square hollow ring plate 9 through the air supply pipe 1 131 and the air supply pipe 2 133, and then be ejected through the multiple air outlet holes 91 opened inside the square hollow ring plate 9, and the hot air is heated to the adhesive at the bonding gap, so that the adhesive at the bonding position is softened, which facilitates the subsequent removal of the adhesive from the detection block. To improve the sealing performance of the connection between air duct 131 and air duct 2 133 and prevent hot air from escaping through the sliding gap between air duct 131 and air duct 2 133, a sealing ring 132 fixedly mounted on the lower end surface of the air duct improves the sliding sealing performance of air duct 131 when it slides inside air duct 2 133, thereby preventing hot air from escaping through the sliding gap between air duct 131 and air duct 2 133 and improving the circulation of hot air. To prevent external debris or dust from entering exhaust fan 137, a dust screen 138 is provided at the air inlet end of exhaust fan 137. This not only prevents dust from entering, but also blocks external objects, preventing them from entering and damaging exhaust fan 137.

[0027] Example 3 like Figure 1-7 As shown, on the basis of Example 1, the present invention provides a technical solution, preferably, the right side of the support frame 2 is fixedly connected with the controller 5, the front and rear side surfaces of the support frame 2 are fixedly connected with two inclined plates, and the back of the support frame 2 is provided with a cleaning mechanism 14, which includes an L-shaped plate 143, one end of the L-shaped plate 143 is fixedly connected to the base 12, one side of the L-shaped plate 143 is provided with a placement frame 144, one end of the placement frame 144 is provided with an entrance 145, one end of the entrance 145 is provided with a scraping frame 146 fixedly connected to the placement frame 144, and the other end of the placement frame 144 is provided with an electric push rod three 142 fixedly connected to the L-shaped plate 143, the telescopic rod of the electric push rod three 142 passes through the L-shaped plate 143 and is slidably connected to the passing part, the telescopic rod of the electric push rod three 142 is fixedly connected to the placement frame 144, the inner wall of the placement frame 144 is slidably connected to the collection frame 141, and the interior of the collection frame 141 is fixedly connected with a pull rod.

[0028] In this embodiment, to facilitate the cleaning of softened adhesive from detection block 1 6 and detection block 2 11, electric push rod 3 142 drives placement frame 144 to move scraping frame 146, causing scraping frame 146 to scrape and clean the softened adhesive from the lower end surface of detection block 1 6 and the upper end surface of detection block 2 11. To facilitate the collection of the scraped adhesive, the scraped adhesive can be allowed to enter placement frame 144 through entry 145 and collected by collection frame 141 placed inside placement frame 144 for subsequent cleaning. To facilitate the subsequent cleaning of the adhesive collected in collection frame 141, a pull rod is provided to facilitate the subsequent user to directly pull collection frame 141 out from placement frame 144, thereby cleaning the adhesive collected in collection frame 141.

[0029] Example 4 like Figure 1-7 As shown, on the basis of Example 1, the present invention provides a technical solution. Preferably, the lifting mechanism includes a lifting plate 3 that is slidably connected to the inner wall of the support frame 2, and the upper end of the lifting plate 3 is provided with an electric push rod 1 that is fixedly connected to the support frame 2. The telescopic rod of the electric push rod 1 passes through the sliding connection support frame 2 and is fixedly connected to the upper end surface of the lifting plate 3. Limiting grooves 22 are provided on the left and right side surfaces inside the support frame 2, and the inner wall of the limiting groove 22 is slidably connected to the limiting slider 21, and one end of the limiting slider 21 is fixedly connected to the lifting plate 3.

[0030] In this embodiment, when the adhesive bond strength test for dental fluorosis veneers is required, the electric push rod 1 drives the lifting plate 3 to rise and fall within the support frame 2, thereby driving the testing block 6 to rise and fall, thereby performing the bond strength test. To improve the stability of the lifting plate 3 as it rises and falls within the support frame 2, the lifting plate 3 drives the limiting slider 21 to slide within the limiting slot 22 when it rises and falls within the support frame 2, thereby improving the stability of the lifting plate 3 as it rises and falls within the support frame 2.

[0031] The specific working principle and method of use of the present invention are as follows: The present invention provides a device for detecting the bonding strength of dental fluorosis veneer adhesives. Figure 1-7As shown, during use, the device is powered by an external power supply. Fluoride veneer adhesive is applied to the upper end of detection block 2 11. Then, electric push rod 1 controls the lifting plate 3 to descend, causing detection block 1 6 to descend, so that the lower end of detection block 1 6 presses against the fluoroide veneer adhesive applied to the upper end of detection block 2 11. Then, controller 5 controls electric push rod 2 10 to retract the connecting curved plate 7 to its minimum position. At this point, the square ring plate 8 is positioned exactly at the bonding position between detection block 1 6 and detection block 2 11. The LED curing light 81 illuminates the adhesive at the bonding position, increasing the curing rate and facilitating rapid bond strength testing. When curing is complete, electric push rod 1 controls the lifting plate 3 to ascend, causing detection block 1 6 to ascend, pulling the adhesive at the bonding position to perform bond strength testing. The tension sensor 4 detects the tension applied to the adhesive, which is displayed on the display screen of controller 5.

[0032] After the subsequent bonding strength test is completed, the electric push rod 2 10 drives the connecting bend to extend to the maximum limit. At this time, the position of the square hollow ring plate 9 is just moved to the bonding position of the detection block 1 6 and the detection block 2 11. By starting the blowing fan 137 and the electric heating pipe 135, hot air is input into the interior of the square hollow ring plate 9 through the air supply pipe 1 131 and the air supply pipe 2 133, and then ejected through the air outlet 91, and the adhesive at the bonding position is heated by hot air to soften the adhesive at the bonding position, which is convenient for removing the adhesive from the detection block. After the adhesive is softened, the electric push rod 1 is controlled to make the lifting plate 3 drive the detection block 16 to rise to the maximum height, and then the electric push rod 2 10 is controlled to move the square hollow ring plate 9 downward to avoid affecting the movement of the scraping frame 146, and then the electric push rod 3 142 is controlled to make the placement frame 144 drive the scraping frame 146 to move, so that the scraping frame 146 can scrape and clean the softened adhesive on the lower end surface of the detection block 16 and the upper end surface of the detection block 2 11, and the scraped adhesive enters the collection frame 141 through the entry port 145 for collection, which is convenient for subsequent cleaning. Later, you only need to pull the pull rod inside the collection frame 141 to take the collection frame 141 out of the placement frame 144 to clean the adhesive collected inside the collection frame 141.
