Description

Technical Field

[0001] The utility model relates to a copper clad laminate production technology, in particular to a glue mixing system. Background Art

[0002] Glue adjustment is the first and most important process in the production of copper clad laminates. The physical and chemical properties of the adjusted glue (physical properties for short) directly affect the physical properties of subsequent products such as prepregs (also known as bonding sheets) and copper clad laminates. The key physical property of the glue, the viscosity of the glue, will gradually increase as the glue solvent evaporates during the gluing process. How to ensure the stability of the glue viscosity during the gluing process is a crucial issue.

[0003] Chinese patent document CN109806796A discloses a movable glue mixing system, including a dissolving glue tank, a front filter barrel connected to the glue outlet of the dissolving glue tank through a pipeline, a homogenizer connected to the front filter barrel through a pipeline, and a rear filter barrel connected to the outlet of the homogenizer through a pipeline, and the rear filter barrel is connected to the dissolving glue tank through a pipeline. The movable glue mixing system uses movable components, and the glue mixing and gluing are not limited by time and machine. The glue can be mixed at any time. After the glue liquid is mixed, it can be used with any machine for gluing and production, and the glue mixing amount is flexible. However, the movable glue mixing system has the following disadvantages: (a) the raw materials such as solvents and liquid resins cannot be filtered when they are directly added to the glue mixing tank, which will cause contamination of the glue liquid; (b) if the filter screen needs to be replaced during the internal circulation of the glue mixing, the filter barrels are connected in series and the glue mixing can only be stopped to replace the filter screen, which affects the production efficiency; (c) there is no control system, and the physical properties of the glue liquid such as glue temperature, glue viscosity, liquid level, etc. cannot be monitored and adjusted.

[0004] Chinese patent document CN217988995U discloses a glue mixing system with reusable cleaning liquid, which includes a glue tank body, a spray device, an external circulation device, a stirring device and a feeding device. The stirring shaft protective cover is installed on the inner side of the top of the glue tank body. The feeding device is directly connected to the inside of the glue tank body through a ball valve and a feeding pipe on the one hand, and is connected to the spray device through a ball valve and a spray pipeline on the other hand. The ball valve is used to control the liquid flow. The external circulation device is directly connected to the inside of the glue tank body through a ball valve and a circulation pipe on the one hand, and is connected to the spray device through a ball valve and a spray pipeline on the other hand. The cleaning liquid reusable glue mixing system effectively blocks the splashing solvent during cleaning by adding a stirring shaft protective cover on the inner side of the top of the glue tank body, which can prevent the solvent from washing away the dust, impurities, debris or aging glue agglomeration adhered to the stirring shaft, and can avoid the solvent from contacting the sealing ring to cause oil leakage. However, the glue mixing system with reusable cleaning fluid has the following disadvantages: (a) the cleaning fluid is not filtered when used, which may cause secondary pollution; (b) the spray pipeline is connected to an external pneumatic pump and is not suitable for a mobile glue mixing system.

The viscometer 11 measures the viscosity and feeds it back to the controller 3. The controller 3 controls whether the solvent is added according to the set viscosity) - glue adjustment external circulation is completed (the glue application is completed, and the glue adjustment system is completed) - spray cleaning (the cleaning liquid enters the second filter barrel 902 from the first feed port 1003 and then enters the spray device 203 through the fifth pipeline 5 to spray and clean the glue adjustment tank 2).
