Abstract:
A board transmitting device for an upright PC board etching machine, comprising a plurality of units, each of which includes a U-shaped frame with a pair of serial wheel frames uprightly inserted in an upper end of both sides thereof, a rotation transmitting wheel disposed between and at one end of said U-shaped frame into which said serial wheel frames are inserted, and a power steering wheel disposed at the other end of said U-shaped frame opposite to said serial wheel frames, said plurality of units being mounted continuously to form an array of board transmitting devices an upright transmitting PC board of a certain length, to drive a rotary shaft that passes through each of said power steering wheels so that each of said wheel frames and each of said rotation transmitting wheels rotate synchronously, and so that a clearance defined between two adjacent ones of said rotary wheels on each pair of said serial wheel frames can positively clamp and advance an upright PC board at a fixed-speed and with a fixed displacement space to ensure transmission and facilitate maintenance so as to enhance etching operations, each component of each of said units being formed with inter-engageable engaging members.
