Description

Technical Field

[0001] This utility model relates to the technical field of adhesion testing devices, and in particular to a surface adhesion testing device. Background Technology

[0002] In many fields, the adhesion properties of material surfaces play a crucial role. In the automotive manufacturing industry, the adhesion between the paint and the car body directly affects the vehicle's appearance durability and corrosion resistance. Insufficient adhesion can cause the paint to peel off, affecting not only the vehicle's aesthetics but also exposing the metal body and accelerating corrosion. In electronic equipment manufacturing, the adhesion between the adhesive and the chip and substrate during chip packaging is crucial to the stability and reliability of electronic components. Poor adhesion can lead to chip loosening or detachment during equipment operation, causing equipment failure. Furthermore, in the architectural coatings and printing and packaging industries, the adhesion of material surfaces also has a decisive impact on product quality and lifespan. As various industries continue to raise their requirements for product quality and performance, the need for accurate testing of material surface adhesion is becoming increasingly urgent.

[0003] Currently, surface adhesion testing devices on the market mainly consist of testing execution components and measuring components. Some traditional surface adhesion testing methods, such as the cross-cut test, rely primarily on human experience to judge the paint film peeling in the scratched area. This is highly subjective, and different testers may have different judgments on the same test sample, resulting in poor repeatability and accuracy of test results. Moreover, the cross-cut test is difficult to accurately reflect the true adhesion performance of some special materials or coatings. For highly elastic coatings, the adhesion may appear good after the cross-cut test due to elastic recovery, but peeling may actually occur under dynamic usage conditions. In addition, some traditional testing methods are cumbersome to operate and have long testing cycles. Taking the pull-out test as an example, a special pull-out head needs to be pasted on the surface of the test sample. After the adhesive has cured, the test is conducted using a tensile testing machine. The entire process not only consumes a lot of time but also requires high-level testing equipment and skilled operators. In large-scale production processes, a large number of products need to be inspected for quality. The inefficiency of traditional testing methods seriously affects production progress and cost control. Utility Model Content
