Description

Technical Field

[0001] This utility model relates to the technical field of coating testing, and in particular to a sheet metal coating adhesion tester. Background Technology

[0002] A coating is a solid, continuous film formed by one or more layers applied to a substrate. The coating usually consists of multiple layers, the number of which depends on the requirements of the object being coated. Generally, it includes a primer layer, an intermediate layer, and a topcoat layer. To ensure the quality of the coating, it is necessary to test the adhesion of the coating. Common adhesion testing methods include the circle test, the grid test, and the pull test.

[0003] Existing coating adhesion testers, such as the one disclosed in utility model patent application number 202320674780.2, mainly include a measuring frame and a testing platform. The testing platform is located on the lower right side of the measuring frame, and a reinforcing side plate is located on the lower left side inside the measuring frame. An instrument display panel is embedded in the upper left end of the measuring frame. A glass testing bottle is placed on the upper surface of the testing platform. An internally threaded sleeve is embedded in the upper support of the measuring frame, and a screw is threaded to the axis of the internally threaded sleeve. In use, the lower surface of the first rubber layer is first coated with a coating... The first rubber layer inside the glass test bottle is coated with a coating. The turntable is then manually rotated to move the screw downwards along the internal threaded sleeve, causing the adhesion detection probe to move downwards and adhere the first rubber layer to the second rubber layer. The turntable is then rotated in the opposite direction to move the screw upwards along the internal threaded sleeve, causing the coating between the first and second rubber layers to slowly separate. The internal movement is observed through the glass test bottle. The adhesion detection probe transmits the adhesion strength information as an electrical signal to the instrument display panel and displays the adhesion strength data.

[0004] However, most existing testing instruments use transparent tape to connect the probe to the sheet metal parts. The test can only begin after the tape dries, resulting in low testing efficiency. Moreover, the tape is applied manually, which can easily lead to uneven application and affect the test results. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a sheet metal coating adhesion tester that not only cleans the sheet metal parts and probes before applying adhesive, improving the uniformity of adhesive application, but also dries the adhesive after the sheet metal parts and probes are bonded together, thus improving the testing efficiency.

The cleaning mechanism is installed on the testing mechanism and cleans the probe; the adsorption mechanism is installed on the cleaning mechanism and cleans the sheet metal part; the driving mechanism is installed on the cleaning mechanism and drives the coating mechanism to rotate; the coating mechanism is installed on the driving mechanism and applies transparent adhesive to the sheet metal part; both drying mechanisms are installed on the cleaning mechanism and dry the transparent adhesive. The operator places the sheet metal part on the testing mechanism, starts the cleaning mechanism, and the cleaning and adsorption mechanisms clean the sheet metal part and the probe. Then, the cleaning mechanism fixes the sheet metal part, starts the driving mechanism, and drives the coating mechanism to rotate and apply transparent adhesive to the sheet metal part, causing the probe to adhere to the sheet metal part. The two drying mechanisms dry the transparent adhesive. After drying, the testing mechanism performs a pull-out test on the coating adhesion of the sheet metal part.

[0007] Preferably, the testing mechanism includes a work frame, a positioning mold, a hydraulic cylinder, a probe, and a display screen.

Then, the hydraulic cylinder is activated to pull the probe. The pulling force of the hydraulic cylinder is displayed on the display screen, which facilitates the testing of the adhesion of the coating on the sheet metal part.

[0008] Preferably, the cleaning mechanism includes two sets of guide rods, a pressing block, two sets of first electric cylinders, a cutting blade, and a collection box.

The two sets of first electric cylinders push the pressing block along the two sets of guide rods to the far left, facilitating the placement of the sheet metal part in the positioning groove of the positioning mold. Then, the two sets of first electric cylinders retract, pulling the pressing block to the right, allowing the adsorption mechanism to clean the upper surface of the sheet metal part. During the movement of the pressing block, the cutting blade removes residual glue and coating from the probe surface, which fall into the collection box for collection.

Both sets of connecting plates are mounted on the rotating shaft and connected to the two sets of springs respectively. The electrostatic adsorption roller is rotatably mounted between the two sets of connecting plates. The pressing block drives the rotating shaft to move, causing the electrostatic adsorption roller to roll on the surface of the sheet metal part, adsorbing dust from the surface of the sheet metal part. By setting two sets of springs, the two sets of connecting plates are always pushing the electrostatic adsorption roller downwards, making it convenient for the electrostatic adsorption roller to adhere tightly to the sheet metal part.
