Description

TECHNICAL FIELD

[0001] The utility model relates to the field of adhesion test technology, and specifically to a desktop full-automatic adhesion test system. BACKGROUND

[0002] Coating adhesion test is a key test widely used in various industries, which detects the adhesion between coating or film and substrate. It is suitable for adhesion test of different materials and coatings, including metal, plastic, glass, ceramic substrate, etc. It has a wide application in paint and paint industry, automobile industry, aerospace industry, construction industry, etc. Through this test, the adhesion of various materials and coatings can meet the requirements, improve the quality and performance of products, and promote the sustainable development of various industries.

[0003] Regarding the cross-hatch and tape test method: the knife width is about 0.1mm~0.5mm, and the interval is 1mm~4mm, which can be divided into 1~11 grids. When drawing a straight line, a straight line mark with the same interval will appear according to the setting. When drawing a straight line mark, a square with multiple grids will be formed. When drawing a cross-hatch, it should cut the substrate, not just the paint, otherwise the test will not be valid.

[0004] After drawing the cross-hatch, the surface must be cleaned with air blowing or brush to remove the debris. Then, the tape test is used to check if it will fall off. First, clean the surface debris, then paste the tape on the cross-hatch position, press the tape tightly with your fingers, and then tear the tape with instant force. Observe whether the paint on the substrate has fallen off, and thus determine the adhesion level of the coating.

[0005] The traditional cross-hatch tester is small in size, suitable for placing on the desktop for operation. The sample is placed manually, the weight of the cross-hatch is adjusted, and then the cross-hatch test can be performed. The shortcomings of this instrument are that it can only draw cross-hatch, and the rest of the air blowing, brush cleaning, tape pasting and tearing, and adhesion level identification need to be operated manually. Although the automatic equipment can complete all the actions automatically, it occupies a large area and has high development and use cost.

[0006] Therefore, a desktop full-automatic adhesion test system is developed, which has the characteristics of desktop placement. In addition to being able to complete the traditional manual placement of the sample plate and the crosshatch test, it can also realize automatic blowing, brush cleaning, tape sticking and tearing, and visual identification of the adhesion level. The system uses a motor and a screw rod module to simulate manual crosshatching, and can set the crosshatch length and interval distance. Manual weight blocks are added to maintain the consistency of the crosshatch force. The system has automatic blowing and slag receiving functions. The system mechanism simulates manual tape sticking, simulates finger pressing back and forth to tightly stick the tape, and then tears the tape with an instant force. The visual intelligent identification of the sample coating surface shedding rate automatically identifies the coating adhesion level and automatically maintains the data. Therefore, the precision of the test results is ensured, and the hands of the experimental personnel are freed. Practical new type content
