Title: Lead bending apparatus
Inventor: MORISHITA YOSHIHIKO
IPC: H01L23/50
Filed: 1986-09-03
Abstract: PURPOSE:To decrease frictional resistance when leads are bent, by positively rotating a lead bending roller by a gear, which is coaxially provided with respect to the roller, and gear groove parts of the side surfaces of a pushing stage and a receiving stage, which are arranged so as to engage with the gear, and imparting a compressing force to the group of the outer leads. CONSTITUTION:An outer lead group 2 is guided out of the outer surface of a package of a semiconductor device 1, which is packaged with a resin. The lead group 2 is held and fixed by a receiving stage 3 and a pushing stage 4. A gear 7 is provided at one end part of a lead bending roller 5. The gear 7 is engaged with gear groove parts 8, which are arranged on the side end parts of the receiving stage 3 and the pushing stage 4. The gear 7 is rotated together with the lead bending roller 5 as a unitary body, with a supporting rod 6 as a shaft. A compressing force is applied in the direction of P toward the side surfaces of the pushing stage 4 and the receiving stage 3 with the supporting rod 6. Then, the roller 5 is rotated by the intermesh of the gear 7 and the gear groove parts 8 and pushed down. The outer lead group 2 is bent with the compressing force. Thus the frictional resistance at the time of compression can be reduced, and the occurrence of cracks at the boundary part of the resin package part can be prevented.
