TIN PLATING SYSTEM HAVING BELT CLAMPING DETECT APPARATUS

摘要

PURPOSE: A tin plating system having belt clamping detect apparatus is provided to be capable of improving the exactness of a clamping process. CONSTITUTION: A tin plating equipment is provided with a plurality of belt clamper holes(210), clampers(102) for clamping a lead frame(103) at a belt(101) through the belt clamper holes, and a belt clamping detection apparatus. At this time, the belt clamping detection apparatus includes a plurality of light emitting devices(201), light receiving devices(202) opposite to each light emitting device through the lower portion of the belt clamper hole, and a support part(203) for supporting the light emitting devices and the light receiving devices. Preferably, the tin plating equipment further includes the second light emitting and receiving devices opposite to each other between the first lower portion of the belt and the second lower portion of the lead frame.
