Description

Board Transmitting Device for Upright PC Board Etching Machine {Board Transmitting Device for an Upright PC Board Etching Machine}

1 is a schematic diagram of a conventional butterfly clamping suspension delivery mechanism. The plurality of clamps 20, 21, ... are separated at appropriate intervals, and are fixed to the moving rail 10 to fix the PC board 30 to proceed. The spray nozzles etch the circuit by spraying the caustic on the plates at the outer ends of both plates. Since the lower end of the PC board 30 is suspended, it will be shaken by the pressure generated by the spraying of the caustic, and the clamping force of the clamps 20, 21 ... will gradually decrease. do. Often, the clamps 20, 21 ... cannot hold the PC board 30 tightly and can fall. Therefore, the etching effect is not good and affects the etching process.

2 shows a vertical delivery mechanism of an etching machine. The PC board 40 stands on the conveyor 50, and a plurality of thin lines 60, 61 ... are provided on both sides of the PC board 40 to prevent the PC board 40 from shaking. Hairline 60, 61, so as not to grip the PC board 40 too tightly to prevent the PC board 40 from proceeding on the conveyor 50, hairline 60, 61 Can't get too close to the PC board. Due to the barrier effect of loose wires 60, 61 ... during the spraying of the caustic agent on the PC board 40, the PC board 40 will shake, which affects the etching effect. In addition, the PC board 40 is simply placed on the conveyor 50 and is not securely fixed in position. Accordingly, the PC board 40 may be misplaced by the force that is injected when the caustic injection mechanism passes on both sides of the board, so that the PC board 40 proceeds at an inconsistent speed, which affects the etching effect. It has a significant effect.

SUMMARY OF THE INVENTION An object of the present invention is to provide a board transfer apparatus for use in an upright PC board etching machine, wherein the above-described board transfer apparatus includes a plurality of series of wheel frames having a rotating wheel mounted on the apparatus, This allows the PC board to proceed stably at a constant speed.

3 shows a unit of a board transfer apparatus for use in an upright PC board etching machine of the present invention. As shown, the unit comprises a pair of wheel frames 200, 300, U-shaped frame 100, a series of wheel frames 200, 300 inserted perpendicularly to the upper ends of both sides. ) Is rotated between one end of the U-shaped frame 100 is inserted, and the other of the U-shaped frame 100 opposite the series of wheel frames 200, 300 And a power steering wheel 500 disposed at one end.

Referring to FIG. 4, a cross-shaped pivoting arm 101 is formed at upper ends of both sides of the U-shaped frame 100. Each pivoting arm 101 is provided with holes 102 and 103 in the vertical and horizontal directions. A series of wheel frames 200, 300 are inserted into the vertical holes 102. The shaft 104 is pivotally connected to the rotational transmission wheel 400 through the horizontal hole 103. Positioning posts 105 extend vertically from two respective sides of the bottom end of U-shaped frame 100 and are inserted into corresponding positioning holes in the etching machine. The power steering wheel 500 may be a spiral rod, while the rotational transmission wheel 400 may be a rotation wheel. Since the series of wheel frames 200 and 300 have the same structure, an example in which only a series of wheel frames 200 is used in the present invention is given. The series of wheel frames 200 is composed of a series of rotating wheels 202, 203, ..., a frame shaft 201, a drive gear 210, a plurality of connecting tubes 220, 221, ..., and transfer wheel 230. The drive gear 210 is fixed to the frame shaft 201 close to the power steering wheel 500 and engaged with the power steering wheel 500. The transmission wheel 230 is fixed to the frame shaft 201 extending through the vertical hole 102, and the transmission wheel 230 is engaged with the rotation transmission wheel 400. The rotary wheels 202 and 203 are arranged to be separated at appropriate intervals by the connecting tubes 220, 221, ..., and are mounted at the intermediate end of the frame shaft 201. Both sides of the hub and protrusions of the respective rotating wheels 202 and 203 from opposite ends of the respective connecting tubes 220 and 221 are crowned engagement members 202A of complementary shapes. , 202B, 203A, 203B, 220A, 220B, 221A, 221B, each rotating wheel 202, 203, ... and each connecting tube 220, 221 are internally tightly engaged in a line by engagement members 202A, 202B, 203A, 203B, 220A, 220B, 221A, and 221B. . The engagement members can be easily separated from one another so that each component can be replaced. In addition, after the engagement member is engaged internally, the member makes it possible to reliably transmit power through each engagement member.
