Description

TECHNICAL FIELD

[0001] The utility model belongs to brush roller pressurization technical field especially relates to a brush roller pressurization mechanism. BACKGROUND

[0002] In the circuit board production process, the copper plate substrate for manufacturing circuit board needs to be surface treated. This requires "roughening" work on the copper plate surface, which requires the use of a grinding machine for operation. The grinding machine uses volcanic ash (also known as pumice powder) as the working medium. When the volcanic ash is mixed with water and flows to the workpiece surface through the pressure pump, the high-speed rotating grinding brush wheel carries the mixture of water and volcanic ash on the copper surface of the workpiece, producing a nearly uniform rough surface on the copper surface, thereby enhancing the bonding force of the copper surface with the electroplated layer, dry film or green oil.

[0003] In related technology, a grinding machine is disclosed, which includes a machine shell, a grinding brush mechanism arranged on the machine shell, and a brush cleaning device of the grinding brush mechanism. The brush cleaning device includes first, second, and third brush cleaning structures for respectively driving all upper grinding brush wheels, all lower grinding brush wheels, and all upper back pressure rollers to rise or fall as needed. The first, second, and third brush cleaning structures have the same structure, which includes: a plurality of first worms, each first worm being connected to one of the upper grinding brush wheels, one of the lower grinding brush wheels, or one of the upper back pressure rollers through a lifting screw; all first worms connected to the upper grinding brush wheels, the lower grinding brush wheels, or the upper back pressure rollers are connected through a synchronous wheel, and one of the first worms is provided with an adjustment controller for driving the first worm to rotate. This improves the reliability and efficiency of the grinding process, has strong adaptability, stable and reliable work, and low noise.

[0004] However, the above structure still has deficiencies.
