Description

Technical Field

[0001] The utility model belongs to the technical field of thin films and relates to an auxiliary detection device for thin film roughness. Background Art

[0002] Plastic film products are flexible sheets with a thickness of less than 0.25mm. There are many types of films, including polypropylene film, polyethylene film, polyvinyl chloride film and polyester film, and there are many ways to form and process the film, such as extrusion, blow molding, calendaring, cast film and stretching. This determines that the film can be widely used in the optoelectronics industry, electronic and electrical industry, fiberglass industry, building materials industry, printing industry, medicine and health and other fields.

[0003] At present, the high-end field has higher and higher requirements for the physical properties of films, and roughness is one of the very important physical properties. Roughness is used to characterize the surface quality characteristics of the film. It refers to the unevenness of the small spacing and tiny peaks and valleys on the surface of the object, which belongs to the microscopic geometric shape error. During the physical processing of the film, it is necessary to add masterbatch to it to increase its windability and improve its smoothness. The masterbatch on the surface of the film makes the surface of the film have a certain degree of roughness. In the high-end field, it is necessary to meet the requirements of film winding and pay attention to controlling the roughness. High roughness will affect the application of film products. For example: During the use of the film in the field of OCA glue, the roughness needs to be strictly controlled. High roughness will cause glue residue on the OCA release film, thereby affecting the OCA glue.

[0004] Since the film itself is very thin, it is easy to be damaged during the handling process, so try to minimize handling during the roughness test. In addition, the roughness test is greatly affected by the interference of the external environment. Whether the platform is flat, the vibration of the environment, etc. will affect the roughness test of the film. The roughness of each area of ​​the film surface is different. Because the test points are different, the test results may vary greatly. Therefore, we must ensure that the test area selected on the film surface is consistent to reduce the influence of the pick-up point on the roughness test results.

[0005] CN202222044093 provides an automatic roughness detection device, which can drive the plate to move laterally through the rotation of two transmission belts, thereby facilitating the detection component to perform roughness detection on the plate. However, only a single direction can be selected for roughness testing, and it is impossible to determine whether the platform is horizontal; in addition, the contact position of the roughness test in this patent is not accurate enough, and it cannot be guaranteed that the roughness of the same position is taken for testing each time.

[0006] CN202223034796 provides a surface roughness detection device, including a base and a measuring bracket slidably mounted on the base, on which a working arm is rotatably mounted; a detection head is mounted on a connecting frame at the front end of the working arm, but the device cannot determine whether the platform is horizontal, and can only ensure that the approximate position of the test is consistent, and the accuracy is low.

[0007] Therefore, it is of great significance to study a thin film roughness auxiliary detection device to solve the above problems. Utility Model Content
