Polishing equipment and polishing method

The present invention relates to a polishing apparatus and a polishing method using the polishing apparatus for polishing.

Currently, polishing equipment commonly used in the industry includes a relatively disposed load bearing lower plate and a polished upper plate. The fixture is placed on the lower tray to secure the work piece. The fixed jig rotates in a clockwise or counterclockwise direction as it carries the lower disk. The polishing brush is disposed on a side of the polishing upper disk facing the lower disk, and the polishing brush rotates with the polishing upper disk, and the polishing upper disk is opposite to the rotation direction of the carrying lower disk. When the working piece is polished, the working piece is fixed on the fixing jig carrying the lower plate, and the polishing upper disk and the carrying lower plate are driven to rotate in opposite directions, and the polishing brush abuts the surface of the working piece and polishes the same.

However, the above polishing apparatus is limited to the limitation of its structural design, and the movable line production cannot be achieved. That is, the machine table must be shut down and replaced when the upper and lower lenses of the machine stand, which causes the polishing device to have a low actuation rate and cannot effectively improve the operation time of the device. And the operation mode of the polishing device is that the upper and lower disks rotate in the opposite direction, and the difference between the linear velocity of the inner and outer diameters of the polishing brush and the number of the brush arrangement causes poor polishing effect and uneven wear of the inner and outer diameter brushes, thereby Affects the life of the polishing brush.

The present invention provides a polishing apparatus having a better actuation rate.

A polishing apparatus includes a polishing mechanism and a conveying mechanism. The transmission agency will vote The work piece placed thereon is transported in a predetermined direction. The polishing mechanism is mounted above the transport mechanism and is reciprocally movable in a direction perpendicular to a predetermined direction of the bearing surface of the parallel transport mechanism. The polishing mechanism includes at least one polishing roller, the rotation axis of the at least one polishing roller being perpendicular to a predetermined direction and parallel to a bearing surface of the conveying mechanism. The at least one polishing roller rotates about its rotation axis and reciprocates with the polishing mechanism in a direction perpendicular to a predetermined direction of the bearing surface of the parallel conveying mechanism for polishing the workpiece conveyed by the conveying mechanism.

A polishing method for polishing using the above polishing apparatus, comprising the steps of: conveying a workpiece placed on a conveying mechanism in a predetermined direction; driving the polishing mechanism in a direction of a vertical conveying direction of a bearing surface of the parallel conveying mechanism Reciprocatingly moving, the at least one polishing roller rotates along the rotating shaft and reciprocates in a direction perpendicular to the preset direction of the polishing mechanism in the bearing surface of the parallel conveying mechanism; after the workpiece is transferred to the polishing mechanism, the at least one polishing roller abuts The working piece is polished in a preset direction and a vertical preset direction.

Since the conveying mechanism of the present invention conveys the workpiece placed thereon in a predetermined direction, the polishing mechanism is erected above the conveying mechanism, so that the polishing mechanism can polish the conveyed workpiece while being conveyed to the rear of the polishing mechanism. The working piece to be polished is placed on the mechanism, and the polished working piece on the conveying mechanism in front of the polishing mechanism can be taken out to form a moving wire polishing operation, thereby improving the actuation rate of the polishing device. And the reciprocating movement of the polishing mechanism in the vertical preset direction can make the polishing roller uniformly wear and prolong the life of the polishing mechanism.

In this embodiment, the transport mechanism 30 may be provided with a conveyor belt, and the work member is fixed on the fixed jig 20, and the conveyor belt transports the fixed jig 20 and the work piece in a predetermined direction. In this embodiment, the conveying mechanism 30 is two conveyor belts respectively disposed on opposite sides of the receiving cavity 12, and the fixing jig 20 can be placed on the two conveyor belts and moved along the preset direction with the two conveyor belts.

The polishing mechanism 40 is mounted above the transport mechanism 30 and driven by the drive mechanism 80 Reciprocating in the direction of the bearing surface of the parallel conveying mechanism 30 and the vertical predetermined direction. The polishing mechanism 40 includes at least one polishing roller 42 whose rotation axis 420 is perpendicular to a predetermined direction and parallel to the bearing surface of the conveying mechanism 30. The at least one polishing roller 42 rotates about its rotation axis 420 and reciprocates in a direction perpendicular to the predetermined direction of the polishing mechanism 40 in the bearing surface of the parallel conveying mechanism for polishing the workpiece conveyed by the conveying mechanism 30.

In this embodiment, the drive mechanism 80 can be driven by a pneumatic cylinder. The plurality of at least one polishing roller 42 is plural, and the plurality of polishing rollers 42 are arranged side by side in a predetermined direction. And the number of the plurality of polishing rollers 42 can be changed according to the polishing range requirement of the device. In this embodiment, the polishing mechanism 40 further includes a cover 41 that is reciprocated by a pneumatic cylinder. The cover 41 includes an upper cover 410 and two opposite side plates 412 connected to the upper cover 410. Both ends of the rotating shaft 420 of each polishing roller 42 are rotatably fixed to the two side plates 412. The material of the polishing roller 42 can be selected from materials such as nylon, cerium oxide, sheepskin, and bristle.

The upper cover 410 is provided with a spray line 502, and the polishing liquid spraying mechanism 50 communicates with the upper cover 410 via a polishing liquid spray line 502 to spray the polishing liquid between the polishing roller 42 and the workpiece. . And after the polishing liquid is used, it is concentrated to the bottom 120 of the receiving chamber 12 and discharged to a recycling barrel 128 via the liquid discharging port 124.
