Description

Mobile phone protection film detection tool

Technical Field

The utility model relates to a cell-phone protection film production check out test set field especially relates to a cell-phone protection film detection tool.

Background

The mobile phone protective film is also called as a mobile phone film, can be used for cold mounting films attached to mobile phone bodies, screens and other tangible objects, and can also be used for mounting MP3, MP4, computer screens, mice, sound boxes and any solid objects needing protection, and is generally called as a mobile phone protective film because the mobile phone protective film is originally widely applied to mobile phones. The waterproof, dustproof and anti-falling effect is achieved, and meanwhile, the attractiveness can be improved by adding color pictures. The existing mobile phone protective film generally comprises an upper protective layer, a middle using layer and a lower release layer, wherein the middle using layer is finally adhered to a protected mobile phone screen, the upper protective layer and the lower release layer are arranged for facilitating the adhering operation, the lower release layer is firstly peeled off when the film is adhered, then one exposed surface of the middle using layer is adhered to the mobile phone screen, then the mobile phone protective film is pushed and pressed by a tool, so that air between the mobile phone protective film and the mobile phone screen is completely discharged, bubbles are avoided being generated (the upper protective layer plays a role in facilitating the contact and pushing of the tool in the step), and finally the upper protective layer is peeled off. Therefore, the required separation force of the lower release layer and the intermediate use layer during peeling is required to be smaller than the required separation force of the upper protective layer and the intermediate use layer during peeling, otherwise, the intermediate use layer and the upper protective layer are driven to separate during peeling of the lower release layer, and the corresponding mobile phone protective film has quality problems.

In order to control the product quality, a sampling inspection mode is adopted in the prior art for inspection, that is, a certain amount of mobile phone protective films are extracted from the mobile phone protective films in the same batch for inspection, a tensile machine is generally adopted in the prior art for inspection, specifically, a gripper of the tensile machine is used for peeling off the lower release layer to measure the separation force required by the peeling of the lower release layer and the middle use layer, then the upper protective layer is peeled off to measure the separation force required by the peeling of the upper protective layer and the middle use layer, and the sizes of the upper protective layer and the middle use layer are compared to determine whether the product quality is qualified. During detection, the mobile phone protective film needs to be positioned through a clamping mechanism on a tensile machine, then a part of the lower release layer is peeled off, then the peeled part is connected with a gripper of the tensile machine, and then the measured data is peeled off by tearing. Because use fixture to carry out the centre gripping to cell-phone protection film, consequently can't come the judgement through peeling off of lower release layer whether can drive the separation of middle use layer and upper protective layer, just also need measure that side of upper protective layer with same mode again, then carry out the comparison of pulling force numerical value. The detection instrument is complex in use and operation and low in detection efficiency. In addition, the peeling scene in actual use cannot be simulated by using the tensile machine for detection, the force of the tensile machine during detection acts in the direction almost vertical to the mobile phone protective film, and the direction of the manual tearing force during use is the direction inclined relative to the mobile phone protective film, so the following situations can occur: the conclusion that the product quality is qualified is obtained through numerical comparison during detection, but problems occur during actual use.

In view of the above, there is a need to provide a new technical solution to overcome the problems in the prior art.
