Embodiment Construction
[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0024] see figure 1 A mechanism for grinding and removing impurities of BGA solder balls according to the present invention includes a frame 10, the frame includes a base 11 and a beam 12 above the base, and a carrier plate is movable on the base 11 20. A pair of parallel linear guide rails 30 are formed on the upper end surface of the base 11. The carrier plate 20 is arranged on the linear guide rails 30. The linear guide rails are elongated guide grooves formed on the upper end surface of the base 11. A pair of guide blocks 21 cooperating with the guide grooves are formed on the bottom surface of the carrier plate 20. The guide blocks 21 are inserted in the guide groove...

The invention discloses a polishing and impurity removal mechanism for BGA solder balls. The polishing and impurity removal mechanism comprises a rack. The rack comprises a base and a beam located above the base. A carrier plate is movably arranged on the base and provided with a first polishing mechanism. A drive mechanism is arranged on the portion, on one side of the first polishing mechanism, of the carrier plate. A second polishing mechanism is arranged above the first polishing mechanism. An impurity removal mechanism is connected to the second polishing mechanism and mounted on a lifting air cylinder. The lifting air cylinder is mounted on the beam. The impurity removal mechanism comprises dust suction pipes fixedly connected to the top ends of second polishing pieces. The dust suction pipes are connected with a suction fan. By means of the polishing and impurity removal mechanism, the surface quality problems of the vaporific or wrinkled surfaces of the solder balls and the like can be solved effectively, the surface roughness of the solder balls is lowered effectively, and chippings and impurities generated in the polishing process can be removed effectively.
Description
Technical field: [0001] The invention relates to the technical field of BGA solder ball processing equipment, in particular to a mechanism for grinding and removing impurities of BGA solder balls. Background technique: [0002] BGA solder balls are an important part of BGA soldering. Automatic BGA solder ball feeding mainly includes cutting and remelting molding methods and spray molding methods. The former is to cut solder wires of different diameters into units of consistent quality, and then process them in glycerin. Melting into balls; the latter is to melt the solder in a specific container (crucible), then inflate the crucible, increase the pressure to make the melted solder eject from a specific small hole at the bottom of the crucible, and then use high-frequency oscillation Make it into a ball. Regardless of whether the solder balls formed by the cutting and remelting molding method or the spray molding method have surface quality problems such as uneven surface an...
