Description

Technical Field

[0001] This utility model relates to the field of adhesive testing technology, and in particular to an adhesive bonding testing device. Background Technology

[0002] Adhesives, also known as binders, are non-metallic media materials that tightly bond one object to another. While the adhesive occupies only a thin layer between the two bonded surfaces, the resulting adhesive-bonded joint meets all the required mechanical and physicochemical properties. It effectively bonds materials together.

[0003] In existing adhesive bonding testing devices, a large amount of adhesive accumulates on the surface of the bonding plate during long-term testing of adhesives. Because it is difficult to disassemble and clean the device separately, the residual adhesive layer may interfere with the detection when testing new adhesives, which may reduce the accuracy of the test. Therefore, this application proposes an adhesive bonding testing device. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the prior art that residual adhesive layers can easily interfere with the detection of new adhesives, thus reducing the accuracy of the detection. This invention proposes an adhesive bonding testing device.

[0005] The technical solution of this utility model: an adhesive bonding testing device, including a base plate, on which a testing chamber is welded, and further comprising:

[0006] A motor cover is welded to the top of the test chamber. An electric push rod is bolted to the top of the inner wall of the motor cover. A connecting rod is fixedly connected to the bottom of the electric push rod. An upper adhesive plate is connected to the connecting rod. A lower adhesive plate is provided below the upper adhesive plate. An installation plate is fixedly installed on one side of the inner wall of the test chamber.

[0007] A removal device, which is mounted on the mounting plate, is used for the automatic scraping of adhesive adhering to the lower bonding plate;

[0008] An auxiliary mechanism, which is installed inside the test chamber, is used to assist in cleaning the removal device.

[0009] Optionally, a connecting ring is connected to the upper surface of the upper adhesive plate, a traction rope is connected to the connecting ring, a spring force gauge is connected to the top of the traction rope, and the spring force gauge and the connecting rod are connected to each other.

[0010] Optionally, a lower adhesive plate is fixedly installed on the bottom inner wall of the test chamber, and an electric heating plate is provided at the bottom end of the lower adhesive plate, with an electric heating wire embedded inside the electric heating plate.

[0011] Optionally, the removal device includes a slide groove fixedly mounted on a mounting plate, a slider slidably mounted in the slide groove, a fixed frame fixedly mounted on the slider, a rotating rod rotatably mounted on the fixed frame, a connecting block fixedly connected to one end of the rotating rod, and a scraper connected to the connecting block.

[0012] Optionally, a lead screw threadedly connected to the slider is rotatably installed inside the slide groove, and a drive motor is fixedly installed on one side of the slide groove, with the output shaft of the drive motor and the lead screw fixedly connected.

[0013] Optionally, the auxiliary mechanism includes a processing box fixedly installed on one side of the inner wall of the test chamber. A rotating shaft is rotatably installed on one side of the inner wall of the processing box. A cylinder is fixedly connected to the rotating shaft. A cleaning brush is provided on the inner wall of the cylinder. Both the cylinder and the processing box are provided with through grooves that match the width of the connecting block.

[0014] Optionally, a slide rail is provided on one side of the bottom wall of the test chamber, and a moving block is slidably installed in the slide rail, with a collection trough fixedly connected to the moving block.

[0015] Optionally, a motor is fixedly installed on one side of the processing box, and the output shaft and the rotating shaft of the motor are fixedly connected.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] This invention utilizes a sliding groove, a slider, a fixed frame, a connecting block, a rotating rod, and a scraper. The sliding of the slider drives the movement of the fixed frame, allowing the scraper to move and scrape away residual adhesive layers adhering to the surface of the lower bonding plate. The rotation of the rotating rod can adjust the scraping surface of the scraper, preventing excessive accumulation of adhesive from affecting the scraping effect of the scraper and avoiding interference from residual adhesive layers in subsequent testing, thus improving testing accuracy.

[0018] Furthermore, by setting up a processing box, a rotating shaft, a cylinder, a cleaning brush, and a through groove, the rotation of the rotating shaft drives the rotation of the cylinder, allowing the cleaning brush to rotate and rub to clean the residual adhesive layer adhering to the scraper surface. This significantly improves the scraping and cleaning effect of the subsequent scraper on the residual adhesive layer and increases work efficiency.

[0019] In summary, this invention enables automatic scraping and cleaning of residual adhesive layers on the surface of the lower bonding plate, and automatically removes excess adhesive from the scraper surface, significantly improving the scraping and cleaning effect of the scraper, avoiding interference from residual adhesive layers on subsequent testing, and improving the accuracy of testing.

[0032] Example

[0033] like Figure 1-3 As shown, the adhesive bonding test device proposed in this utility model includes a base plate 1, a test box 2 welded to the surface of the base plate 1, a motor cover 3 welded to the top of the test box 2, an electric push rod 4 bolted to the top of the inner wall of the motor cover 3, a connecting rod 5 fixedly connected to the bottom end of the electric push rod 4, an upper adhesive plate 6 connected to the connecting rod 5, a lower adhesive plate 7 provided below the upper adhesive plate 6, and a sealed door hinged to one side of the outer wall of the test box 2. A glass observation window is provided on the sealed door to observe the test conditions inside the box.

[0034] In addition, a connecting ring is connected to the upper surface of the upper adhesive plate 6, and a traction rope 14 is connected to the connecting ring. A spring force gauge 15 is connected to the top of the traction rope 14. The spring force gauge 15 and the connecting rod 5 are connected to each other. The adhesive to be tested is applied to the lower adhesive plate 7, and then the upper adhesive plate 6 is pressed onto the lower adhesive plate 7 for bonding. The connecting rod 5 is moved by the push of the electric push rod 4, and the adhesive force is measured in conjunction with the spring force gauge 15.

[0035] In addition, a lower adhesive plate 7 is fixedly installed on the bottom inner wall of the test chamber 2. A heating plate 13 is provided at the bottom of the lower adhesive plate 7. Heating wires are embedded inside the heating plate 13. A controller is provided on the left side of the test chamber 2. The controller enables the heating plate 13 to heat the lower adhesive plate 7, so that the adhesive on the surface can be heated and cured quickly, improving the efficiency of the test. An installation plate 8 is fixedly installed on one side of the inner wall of the test chamber 2.

[0036] like Figure 2-4 As shown, the device also includes a removal device, which is set on the mounting plate 8 for automatically scraping off the adhesive adhering to the lower bonding plate 7. The removal device includes a slide groove 16 fixedly mounted on the mounting plate 8, a slider 17 slidably mounted in the slide groove 16, a fixed frame 18 fixedly mounted on the slider 17, a rotating rod 19 rotatably mounted on the fixed frame 18, and a servo motor for driving the rotating rod 19 to rotate is provided on the back side of the fixed frame 18.

[0037] Furthermore, a connecting block 20 is fixedly connected to one end of the rotating rod 19, and a scraper 21 is connected to the connecting block 20. When the servo motor is started, the rotating rod 19 can drive the scraper 21 to rotate, which is beneficial to adjust the scraping surface of the scraper 21 and avoids the scraping effect being affected when too much adhesive layer accumulates.

[0038] Furthermore, a lead screw 22, which is threadedly connected to the slider 17, is rotatably installed inside the slide groove 16. A drive motor 9 is fixedly installed on one side of the slide groove 16. The output shaft of the drive motor 9 is fixedly connected to the lead screw 22. When the drive motor 9 is started, the lead screw 22 rotates, and the slider 17 drives the fixed frame 18 to move, so that the scraper 21 can scrape and clean the adhesive layer attached to the lower adhesive plate 7, so as to avoid the residual adhesive layer from affecting subsequent tests.

[0039] It is worth noting that a slide rail 10 is provided on one side of the bottom wall of the test box 2. A moving block 11 is slidably installed in the slide rail 10. A collection trough 12 is fixedly connected to the moving block 11. By sliding the moving block 11 in the slide rail 10, the collection trough 12 can be moved to a position close to the lower adhesive plate 7, so that the residual material scraped and cleaned by the scraper 21 enters the collection trough 12 for centralized collection.

[0040] like Figure 2-5 As shown, the device also includes an auxiliary mechanism, which is set inside the test chamber 2 for cleaning assistance of the removal device. The auxiliary mechanism includes a processing box 23 fixedly installed on one side of the inner wall of the test chamber 2. A rotating shaft 25 is rotatably installed on one side of the inner wall of the processing box 23. A cylinder 26 is fixedly connected to the rotating shaft 25. A cleaning brush 27 is provided on the inner wall of the cylinder 26. A spring rod is provided between the cleaning brush 27 and the inner wall of the cylinder 26 so that the scraper 21 entering the cylinder 26 can make good contact with the cleaning brush 27. A motor 24 is fixedly installed on one side of the processing box 23. The output shaft of the motor 24 is fixedly connected to the rotating shaft 25. When the motor 24 is started, the rotating shaft 25 drives the cylinder 26 to rotate, so that the cleaning brush 27 can rotate and rub to clean the residual material attached to the surface of the scraper 21, which is beneficial to improving the scraping effect of the scraper 21.

[0041] It is worth mentioning that both the cylinder 26 and the treatment box 23 have through slots 28 that match the width of the connecting block 20. That is, after each cleaning and scraping of the lower adhesive plate 7, the sliding of the slider 17 drives the scraper 21 to successfully enter the treatment box 23 and finally enter the cylinder 26 to achieve cleaning.

[0042] The working principle of this embodiment is as follows: After testing the adhesive strength of the adhesive, the drive motor 9 is started, causing the lead screw 22 to rotate. The slider 17 drives the scraper 21 to slide, allowing the scraper 21 to move and scrape away the residual adhesive layer adhering to the surface of the lower bonding plate 7. At the same time, the sliding of the moving block 11 in the slide rail 10 causes the moving block 11 to move and abut against one side of the lower bonding plate 7, so that the residual adhesive scraped away by the scraper 21 can be successfully collected in the collection tank 12. After scraping is completed, the sliding of the slider 17 continues to allow the scraper 21 to successfully enter the cylinder 26 through the through groove. At this time, the motor 24 is started, causing the rotating shaft 25 to drive the cylinder 26 to rotate, so that the cleaning brush 27 in contact with the surface of the scraper 21 can rotate and rub to clean the scraper 21. This allows the adhesive adhering to the scraper 21 during the scraping and cleaning process to be successfully removed, significantly improving the subsequent scraping and cleaning effect of the scraper 21 and improving the accuracy of the test.

[0043] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
