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 associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided 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 there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

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 an AF film, it can achieve waterproof, oil-proof, dirt-proof, and anti-fingerprint effects. The uniformity of the AF film layer and the quality of adhesion on the product will affect the aforementioned effect of the product, so usually after the AF coating process is completed, it is necessary to test the AF coating effect of the product. [0003] At present, the AF coating test method 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. For a certain opening angle, it can be judged visually whether it is coated or not. However, the dripping process is manually operated, and the operator...
