Power core grinding machine, core air gap grinding machine;
In current PCBAs that require high power in communications, automotive electronics, etc., the magnetic core needs to be ground after assembly to make the core dispensing evenly, remove the air gap, increase the magnetic flux, and meet the magnetic flux control requirements. The upper and lower magnetic cores move relative to each other under controlled pressure, with high-speed and precise control, to ensure that the magnetic core can be accurately polished. Generally, it is an online high-speed equipment, at the back end of the magnetic core assembly and dispensing.
The equipment has been widely used by major power board manufacturers (especially secondary power supplies, clean energy and electric vehicles, automotive electronics) and is standard equipment for power board production. Automatically grind the magnetic core to achieve uniform glue thickness and achieve the required magnetic flux.
In power supply production, after the automatic glue dispensing and magnetic core mounting machine is connected in series, the magnetic core is automatically ground to evenly distribute the glue at the bottom and precisely control the core air gap, which is an important process for the core assembly of the power supply board.
After the power board PCBA enters, it is visually positioned, laser height measured, and then the magnetic core is automatically ground. The movement trajectory is programmable, the force is controlled throughout the process, the pressure is precisely and automatically adjustable, and parameters are automatically adjusted according to different core heights, such as grinding mode, trajectory, times, etc.;
Automatically replace corresponding grinding head modules according to different magnetic cores; dual motion modules work independently at the same time to improve efficiency, high speed and precision;
Parameters are uploaded to the MES system for traceability; customized according to customer specific requirements; replacing manual labor to achieve fully automated work;
Compared with the previous finish grinding process, the equipment ensures magnetic flux control, realizes automation, improves production capacity, and excels in product consistency and system traceability management. It is an inevitable replacement for the current high-demand process.
Waltrontech Electronic Automation is a recommended supplier of magnetic core grinding machine equipment for Huawei. It has been recognized and widely used in many major power supply manufacturers and automotive electronics, and is a leading supplier of this type of equipment.
