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. One side of the strip is a hypotenuse, and the vertical line of the hypotenuse is parallel to the cone surface of the roller electrode to be processed; the plane of the grinding part of the grinding mechanism is perpendicular to the bottom surface; It fits with the tapered surface of the roller electrode to be processed. The taper of the roller electrode will not be changed during the grinding process, and the flatness of the cone surface is guaranteed. The surface of the roller electrode after grinding is smooth, and there are no abnormal protrusions and pits, and the incidence of sparking during parallel seam welding is reduced. , effectively improving the quality of grinding and repairing the roller electrode to be processed, improving the packaging yield of integrated circuits, improving the efficiency of grinding the roller electrode, and saving the time for packaging integrated circuits.

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...
