Description

Technical Field

[0001] The invention relates to the technical field of polarizer detection, and in particular to a tensile detection device for polarizer detection. Background Art

[0002] The full name of polarizer is polarizing film. The imaging of liquid crystal display must rely on polarized light. All liquid crystals have two polarizers in front and behind that are close to the liquid crystal glass, forming a liquid crystal film with a total thickness of about 1mm. If any polarizer is missing, the liquid crystal film cannot display images. During the production process of polarizers, it is necessary to sample and test the polarizers to test their tensile and scratch resistance. In order to improve the efficiency of polarizer testing, a tensile testing device is needed, but the existing tensile testing device still has the following shortcomings:

[0003] For example, the invention with publication number CN220583954U discloses a tensile testing device for detecting the tensile strength of polarizers. The invention can stretch the polarizer when the first mounting seat and the second mounting seat are away from each other. When the polarizer is stretched, the tensile strength of the polarizer can be detected by a tension sensor, and then the tensile strength data of the polarizer can be obtained, so as to improve the production quality of the polarizer. However, similar to the comparative documents of the above-mentioned application, when the existing tensile testing devices are used, since most of the tensile testing devices only use a single structure to limit and clamp the polarizer, the polarizer is easy to loosen after being subjected to tension, thereby affecting the tensile testing of the polarizer, resulting in the problem of reduced practicality and reduced use efficiency of the tensile testing device.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a tensile testing device for polarizer testing is proposed. Summary of the invention
