Description

Technical Field

[0001] The invention relates to the technical field of coating adhesion detection, in particular to a UV curing coating adhesion detection device and a detection method thereof. Background Art

[0002] UV paint is the abbreviation of Ultraviolet Curing Paint, which is ultraviolet light-curing paint, also known as light-initiated paint. Unlike PU, PE, NC and other paints named after film-forming substances, UV paint is named after the curing method of the paint. It is automatically rolled and poured onto the furniture board by machines and equipment. Under the irradiation of ultraviolet light (wavelength of 320-390nm), the initiator is decomposed to produce free radicals, which trigger the resin reaction and instantly cure into a film. In the prior art, the adhesion test between UV paint and the coated object adopts the hundred-grid knife test, which adopts the tester to manually use the hundred-grid knife test. The knife cuts and penetrates the coating in a grid pattern. The grid-cutting pattern is classified into six levels. The degree of adhesion of the coating to the substrate is assessed by assessing the integrity of the coating within the grid. However, UV paint testing is currently mostly done on finished products, and there is a lack of equipment for testing UV paint stock solutions. This testing method is more complicated, and the tester has more manual operations, which requires a high level of experience. In addition, the internal cutting tools of the existing hundred-grid knives on the market are affected by the sharpness of the blade. After a certain number of tests, the sharpness of the cutting tools decreases, affecting the test data, and the cutting tools need to be frequently replaced, resulting in a lower service life of the internal cutting tools of the hundred-grid knives.

2. A UV curing coating adhesion detection device according to claim 1, characterized in that: The top and rear sides of the hundred-grid cutter (74) are both arc-shaped.

3. A UV curing coating adhesion detection device according to claim 2, characterized in that: The inner cavity of the limiting sliding groove (75) has arc-shaped upper and lower sides.

4. The detection method of a UV curing coating adhesion detection device according to claim 3, characterized in that: The following steps are involved: Step 1: Before use, the staff connects the test UV paint bucket to the pressure pump (52), and pre-loads different types of plates into the left and right plate feeders (11) through the sealed doors (12) on both sides. The plate feeder (11) lifts and transports different types of plates to the surface of the annular conveyor (3) according to the test needs. The annular conveyor (3) transports the plates on its surface in a circumferential circular manner. The plates are moved to the bottom of the spraying mechanism (5). The pressure pump (52) pumps the UV paint into the diverter (53), and the paint is discharged from the first conduit (54) into the pump valve assembly (55) under the diversion effect of the diverter (53). The pump valve assembly (55) controls the opening and closing of its own valve and is discharged from the nozzle pipe (510) under the cooperation of the second conduit (510). 59) is discharged, the first motor (514) drives the rotating disk (515) to rotate, the rotating disk (515) drives the bottom end of the second connecting rod (516) to move circumferentially, and drives the upper rotating shaft (57) to reciprocate under the cooperation of the second connecting rod (516) and the first rotating rod (511), and the upper rotating shaft (57) drives the lower rotating shaft (57) to swing back and forth synchronously under the cooperation of the second rotating rod (512) and the first connecting rod (513) on the upper and lower sides, and the upper and lower rotating shafts (57) drive the nozzle pipe (59) to swing and spray under the cooperation of the counterweight frame (58) to increase the spraying area of ​​the UV paint so that the paint film covers the surface of the plate, and the test sample plate is moved to the bottom of the UV curing lamp (8) for ultraviolet irradiation to accelerate curing; Step 2: After curing, the test sample plate is moved to the bottom of the gridding mechanism (6), the lifting machine (61) controls the lifting height, the rotating module (63) controls and adjusts the rotating direction of the gridding assembly (7), the folding machine (64) drives the gridding tool (74) in the gridding assembly (7) to fit the surface of the test sample plate, and the multi-degree-of-freedom parallel robot arm (62) realizes free movement in multiple directions to enable the gridding tool (74) to draw a grid on the surface of the test sample plate. When the gridding tool (74) fits the surface of the paint film, The front edge of the grid cutter (74) first contacts the plate and moves upward under force, and at the same time squeezes the spring (78) at the corresponding position through the slot seat (76), so that the spring (78) plays a buffering role to avoid damage to the edge of the grid cutter (74). After the grid is drawn, the test sample plate is moved to the tape sticking machine (9) and the internal tape of the tape sticking machine (9) is used to perform an adhesion and shedding test on the paint film on the surface of the test sample plate below. The visual monitoring machine (10) observes and records the surface condition of the paint film on the plate after the test.
