Multistation automatic angle grinder

Abstract

The invention discloses a multistation automatic angle grinder which comprises a stand and is characterized in that an upright plate is arranged at the front part of the stand; a plurality of vertical mainshafts are evenly distributed on the upright plate, wherein a support disc is arranged on the upper end of each mainshaft, a grinding disc is arranged on the support disc, and a chip pressing disc is arranged on the grinding disc; a driving device with two output shaft ends is arranged at the rear part of the stand, wherein one output shaft end is connected with the mainshafts through the driving mechanism; a swing frame is articulated to the stand, wherein a swing shaft is transversely arranged on the upper end of the swing frame in a penetrating way; a push rod is respectively sleeved on the swing shaft corresponding to each grinding disc; the front part of the push rod is pressed in a central hole of the chip pressing disc through a bolt; and the other output shaft end of the driving device is connected with the swing frame through a crank connecting rod mechanism. The multistation automatic angle grinder has the advantages of realizing mechanical and automatic machining, highworking precision, high yield and good machining quality, having lower requirement for the abilities of workers, ensuring that each worker can operate four equipment simultaneously, decreasing the number of workers and reducing the production cost.

Description

technical field [0001] The invention particularly relates to a multi-station automatic angle grinding machine used for completing the angle grinding link in the semiconductor production process. Background technique [0002] In the semiconductor production process, the traditional manual corner grinding process of semiconductor chips is based on the electric rotation of the grinding disc, manually pressing the chip on the grinding disc to slide and grind the corners, and manually filling the sand at the same time. Workers need to make decisions based on experience, so there are high requirements for workers' ability; at the same time, manual grinding is inefficient, low yield rate, and has a certain impact on the quality of finished chips. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-station automatic angle grinding machine with high working efficiency, high yield, good processing quality, low requirem...
