Embodiment Construction

[0031] The present invention is described in further detail below in conjunction with accompanying drawing:

[0032] The invention is a roller electrode grinding device and a grinding method thereof, such as figure 1 As shown, it consists of a roller electrode clamping device, a roller electrode taper control system and a motor 3 .

[0033] Such as figure 2 As shown, the roller electrode clamping device includes a transition shaft sleeve 9 , a pad sleeve 8 , a connecting shaft 10 and a lock nut 7 . One end of the connecting shaft 10 is connected to the output shaft of the motor 3 through the crossing sleeve 9, and is provided with a shaft shoulder, and the other end is screwed with a lock nut 7, and a pad sleeve 8 is nested between the lock nut 7 and the shaft shoulder. The processing roller electrode 1 is fixedly nested between the cushion sleeve 8 and the shaft shoulder.

[0034] The connecting shaft 10 and the lock nut 7 are used for fixing the roller electrode 1 to be ...

Abstract

The invention discloses a roller electrode grinding device and a grinding method thereof. The device comprises a motor, a grinding mechanism and a guide strip; the motor is fixedly arranged, a to-be-machined roller electrode is coaxially fixed on an output shaft, the guide strip is arranged below the output shaft, one side of the guide strip is a bevel edge, and a vertical line of the bevel edge is parallel to a conical surface of the to-be-machined roller electrode; the plane surface and the bottom surface of a grinding part of the grinding mechanism is perpendicular to each other; and duringgrinding, the side surface of the bottom of the grinding mechanism is attached to an bevel edge of the guide strip, and the plane surface of the grinding part is attached to the conical surface of the to-be-machined roller electrode. In the grinding process, the taper of the roller electrode cannot be changed, the flatness of the conical surface is guaranteed, the surface of the polished roller electrode is smooth, and abnormal protrusions and pits are avoided; and the occurrence rate of the sparking phenomenon in the parallel seam welding process is reduced, the quality of grinding and repairing the to-be-machined roller electrode is effectively improved, the packaging yield of an integrated circuit is improved, the grinding efficiency of the roller electrode is improved, and the time for packaging the integrated circuit is saved.

Description

technical field [0001] The invention belongs to the field of integrated circuit manufacturing, and relates to a roller electrode grinding device and a grinding method thereof. Background technique [0002] Roller electrodes are the most basic and most consumable spare parts for parallel seam welding equipment. In the process of parallel seam welding, the roller electrodes are prone to problems such as sparking, wear, and surface flatness reduction, resulting in air leakage or over-melting of the circuit seam welding ring. In order to ensure the reliability of the circuit package, for the problematic roller electrodes, the process needs to be polished with sandpaper in time. [0003] The taper of the roller electrode refers to the angle between the oblique section of the electrode roller and the horizontal plane. The size of this angle determines the size of the contact surface between the electrode and the cover plate during parallel seam welding. The smaller the taper of...
