Description

Film tearing device for LCD display module Technical Field The utility model relates to the technical field of LCD display module dyestripping, in particular to a dyestripping device for an LCD display module. Background The film tearing device for the LCD display module is used as key equipment in the production process of the LCD display module, is mainly used for tearing off the protective film of the LCD display module, plays an important role in the manufacture of electronic display products, and in practical application, the film tearing device for the LCD display module generally needs to use the following technology: 1. The product placing table is used for bearing the LCD display module, provides a stable platform for film tearing operation and is required to have certain flatness and bearing capacity; 2. The tester wears the antistatic glove and the wrist strap, and the handheld display screen module performs film tearing operation at the peeling speed of more than 20 cm/s. At present, manufacturers adopt various devices and modes for realizing the film tearing operation of the LCD display module. Part of manufacturers adopt the mode of manual dyestripping, rely on workman manual operation to tear the protection film, this kind of mode inefficiency, and because different workman's operation methods and dynamics are different, lead to easily tearing the membrane effect inconsistent, influence product quality. And a manufacturer adopts a simple mechanical film tearing device, and although the efficiency is improved to a certain extent, the accurate control of the film tearing process and the effective evaluation of the product performance are lacked, and the influence of the film tearing on the display performance of the LCD display module cannot be accurately judged. However, the above embodiment still has the following problems that in terms of uniformity of the film tearing, it is difficult to ensure that the speed and the path of the film tearing are the same each time, so that the film tearing effect is uneven, the yield of the product is affected, in terms of product performance evaluation, an effective quantitative evaluation means is lacking, the anti-film-tearing electrostatic display performance of the product cannot be accurately judged, and effective control and improvement on the product quality are difficult. Aiming at the problem, the application provides a solution, designs a film tearing device for an LCD display module, and the device realizes quantitative evaluation of film tearing mura degree through automatic film tearing operation and accurate brightness test, so that the test result is more objective and accurate, the inconsistency and subjective judgment error of artificial film tearing are avoided, meanwhile, unqualified products can be rapidly and effectively screened out, the evaluation of the electrostatic display performance of the product for resisting film tearing is realized, scientific basis is provided for quality control and improvement of the product, the quality and production efficiency of the product are improved, and the defective product rate is reduced. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a film tearing device for an LCD display module, which solves the problems that the speed and the path of the manual film tearing are difficult to ensure the same each time, the film tearing effect is uneven, and the yield of products is affected. In order to achieve the above purpose, the utility model is realized by the following technical scheme: The utility model provides a tear film device for LCD display module assembly, includes that the product is placed platform and controller, LCD display module assembly has been placed to the product upper surface, LCD display module assembly surface is provided with easily tears the subsides, LCD display module assembly top is provided with tears membrane manipulator and probe, the product is placed the platform right side and is provided with the tool of lighting a lamp, it is continuous with the controller that the membrane manipulator passes through the circuit to tear.
