Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustr...

Abstract

The invention relates to a film layer liquid detection system, which comprises a conveying line, a coating mechanism and a cleaning mechanism, wherein the coating mechanism comprises a first material guide frame, a first detection device and a water providing device; the first material guide frame is arranged on the conveying line and forms a coating passage; the first detection device is arranged on the first material guide frame; the water providing device is arranged on the first material guide frame, and is positioned at one side, along the material conveying direction, of the first detection device; the water providing device is in communication connection with the first detection device, and is used for coating detection liquid onto a product entering the coating passage in a controllable way according to the detection result of the first detection device. The product enters the first material guide frame through being conveyed through a flow line; when the first detection device detects that the product enters the coating passage and the detection information is transmitted to the water providing device, the water providing device can coat the detection liquid onto the product. Therefore the manual operation is replaced; the labor cost is reduced; the operation efficiency is improved; the occurrence of the missing operation condition is prevented to the maximum degree.

Description

Technical field [0001] The invention relates to the technical field of product surface treatment, in particular to a membrane liquid detection system. Background technique [0002] AF coating is a coating process in a vacuum state through coating equipment. After forming the AF film, it can achieve the effects of waterproof, oil-repellent, stain-resistant, and anti-human fingerprints. The uniformity of the AF film layer and the adhesion on the product will affect the aforementioned effects of the product, so usually after the AF coating process is completed, the AF coating effect of the product needs to be tested. [0003] At present, the AF coating detection of mobile phone cases generally uses the water drop angle test method, that is, the liquid (generally pure water) is dropped on the coating surface of the mobile phone case. Due to the surface tension of the liquid, the liquid surface is formed between the coating surface of the mobile phone case For a certain opening angle, ...
