Description

Technical Field

[0001] This utility model relates to the field of adhesive quality testing technology, specifically to an adhesive quality testing device. Background Technology

[0002] Adhesive bonding, as an advanced material joining process, achieves interfacial bonding of homogeneous or dissimilar materials through adhesives, offering significant advantages such as uniform stress distribution, lightweight construction, and excellent sealing. This technology is particularly suitable for joining dissimilar materials, ultra-thin components, and complex structures, and is widely used in aerospace, electronic packaging, and other fields. As the core material, the quality of the adhesive directly affects the reliability of the connection; therefore, it requires strict quality control through specialized testing equipment. Current adhesive quality testing devices suffer from significant operational flaws: poorly designed sealing systems lead to adhesive leakage during testing, contaminating the equipment's working surface, affecting testing accuracy, and increasing cleaning and maintenance costs. Furthermore, leakage can result in insufficient sample volume, causing data inaccuracies. These problems severely reduce testing efficiency and user experience. Therefore, we propose an adhesive quality testing device. Utility Model Content

It also includes a pulling disc assembly 5, which comprises a pulling disc 51 and a threaded post 52. Two pulling discs 51 are provided, and a threaded post 52 is fixed to the end face of each pulling disc 51. A first threaded groove is formed on the upper side of the moving bar 32, and the right-side threaded post 52 is threaded into the first threaded groove. A storage groove is formed at the right end of the limiting ring 44, and the left-side pulling disc 51 is located inside the storage groove. An opening is formed at the left end of the storage groove, and the left-side threaded post 52 is located inside the opening. A sliding bar 43... A second threaded groove is provided on the right side, and the threaded post 52 on the left side is threaded into the inside of the second threaded groove. The discharge pipe 24 is connected to the inner cavity of the storage tank. The right pull plate 51 is located at the right end inside the storage tank. The threaded post 52 facilitates the disassembly of the pull plate 51 for easy cleaning. The pulling force is measured by the tension gauge 42. At the same time, the adhesive entering the storage tank will flow between the two pull plates 51. At this time, the limiting ring 44 will block the adhesive to prevent leakage.

[0015] Wherein: a limit post 6 is fixed at the lower left end of the moving bar 32, and a groove is opened at the left end of the limit post 6. A pressure sensor 7 is installed inside the groove.

[0017] The working principle of the adhesive quality testing device provided by this utility model is as follows: The external PLC controller first starts the motor 34 to drive the threaded rod 33 to rotate, which drives the moving bar 32 and the right-side pulling plate 51 to move to the right; when the limiting post 6 at the left end of the moving bar 32 contacts the inner wall of the fixed frame 31, the pressure sensor 7 in its groove triggers a signal to stop the motor 34. At this time, the right-side pulling plate 51 precisely enters the right end of the storage groove of the limiting ring 44, forming a standard glue injection gap with the left-side pulling plate 51. Then, the sealing cover 8 is opened to inject adhesive into the storage cavity 21, and the material pump 22 feeds the adhesive. The adhesive is drawn out by pipe 23 and injected into the storage tank through the discharge pipe 24 controlled by solenoid valve 25. The adhesive is precisely filled into the gap between the two pulling discs 51. The annular sidewall of the limiting ring 44 completely wraps the adhesive to achieve dynamic sealing. When the motor 34 is started again, the right pulling disc 51 continues to move to the right to stretch the adhesive. At this time, the left pulling disc 51 slides in the sliding mouth of the mounting block 1 through the slide bar 43 and drives the hook of the tension gauge 42 connected to the left connecting hole of the slide bar 43 to monitor the adhesive separation force value in real time. After the test is terminated, the two pulling discs 51 are disassembled for cleaning by loosening the threaded column 52.

[0018] It is worth noting that the external PLC controller disclosed in the above embodiments is specifically a Siemens S7-200.
