Description

Technical Field

[0001] The present invention relates to the technical field of protective film detection, and in particular to a protective film surface flatness detection device and a detection method. Background Art

[0002] Protective film is a thin film material used for surface protection, which is widely used in electronics, automobiles, home appliances and other industries. It can effectively prevent scratches, dirt and other external factors from damaging the surface of the product, while also providing waterproof, oil-proof and UV-resistant functions. The choice of protective film is usually determined by the material of the object to be protected and the use environment to ensure that the product's service life and appearance are maximized. Protective film surface flatness detection equipment is usually used to ensure the quality and performance of the protective film during the application process.

[0003] Existing protective film surface flatness detection equipment is usually equipped with a laser scanner module to scan the surface of the protective film on the positioning fixture on the lower side of the module and transmit the data to the controller, compare the surface differences of each point to determine whether there is any unevenness. When measuring the protective film sample, the protective film sample is usually positioned by a positioning fixture and then fixed on a placement seat, and then the thickness gauge is aligned with the protective film sample for measurement. When the measurement is completed, the protective film is unlocked and removed, and then the next sample can be measured. Therefore, it takes a certain amount of time to wait, which affects the overall detection efficiency of the sample, makes the sample detection time longer, and is not convenient for detecting more protective film samples. For this reason, we propose a protective film surface flatness detection device and detection method. Summary of the invention

[0004] The object of the present invention is to provide a protective film surface flatness detection device and detection method to solve the problem in the above background technology that the detection efficiency is poor because the previous sample needs to be removed before the next sample can be loaded.

[0013] According to the above-mentioned detection method of a protective film surface flatness detection device:

[0014] S1: Pull out the positioning fixture from the inside of the placement seat, then rotate the upper pressing piece to open the positioning fixture, then unfold the protective film to be tested and place it inside the positioning fixture, then rotate the upper pressing piece to close the positioning fixture so that the protective film is pressed down and positioned;

[0015] S2: Insert the positioning fixture into the clamping cavity. At this time, the position to be detected of the protective film can be matched with the lower side of the detection window. Then the detection module can be opened, and the surface data of the protective film can be detected by the laser scanner. At this time, the data can be displayed on the touch screen after being processed by the control box. The flatness data of the protective film can be obtained through the data on the touch screen.

[0016] S3: When testing a protective film, another protective film to be tested can be positioned using another positioning fixture and then inserted into another placement seat for preparation. When the testing of the previous protective film is completed, the displacement seat can be directly pushed to move so that the detection module fits on the top of the detection window of another placement seat, and continuous detection operations can be performed.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention pulls out the positioning fixture from the inside of the placement seat, and then rotates the upper pressure piece to open the positioning fixture, and then unfolds the protective film to be tested and places it inside the positioning fixture, and then rotates the upper pressure piece to close the positioning fixture so that the protective film is pressed down to position, and then the positioning fixture is inserted into the clamping cavity.

[0020] 3. When the detection is completed, the pulling ring can be pulled upward so that the fitting strip made of the Velcro hook surface on the top of the pulling ring fits onto the rough surface at the bottom of the fixed plate. At this time, the telescopic tube is extended, so that the telescopic tube can be used to block between the detection window and the detection module, preventing external dust and airflow from entering between the detection window and the detection module when the detection device is not in use, causing dust to accumulate at the bottom of the positioning fixture and the detection module, thus eliminating the trouble of cleaning the detection device.
