Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printed circuit board holding and conveying holder in an automatic printed circuit board soldering apparatus, and particularly relates to the function of holding the printed circuit board.

An automatic soldering device uses a driving means such as a conveyor chain to convey a holder holding a printed circuit board along a predetermined trajectory and level.-1 During the conveyance process, soldering line processing and soldering are related processes. This is a well-known fact.

In this case, the printed circuit board to be held in the holder.

Generally, the installation and removal are done manually.

In rare cases, this may be done by automated means.

However, as illustrated in FIG. 1, the holding function of the printed circuit board is achieved by press-fitting both edges of the printed circuit board into the holding grooves C having a U-shaped cross section of a pair of opposing board holders B. In addition, the holding mechanism includes a holding mechanism for holding the printed circuit board A by pressure and holding the portion where the holding groove C is formed in one or both of the board holders B by the inward biasing force of the spring spring E.

Therefore, the holding groove C having a U-shaped cross section is connected to the printed circuit board A.
For this reason, the printed circuit board A held therein has an unstable element in the vertical direction, and the edge of the printed circuit board A, which is the fitted part of the holding groove C, is essential. It has been considered essential to form a constrained surface portion that cannot be occupied by the built-in electrical components as a fitting occupied portion solely for the purpose of fitting and holding.

In view of the above, the present invention has a holding function that makes it possible to hold the printed circuit board stably and firmly, and furthermore, makes it possible to hold the entire surface of the printed circuit board, that is, the edge thereof, even when the printed circuit board is occupied by the mounting area of electrical components. The present invention aims to provide a holder for holding and transporting printed circuit boards.

Details will be described below based on embodiments illustrated in the accompanying drawings.

Figures 2 and 3 are a perspective view and a sectional view of the time preservation and transport holder for printed circuit boards of the present invention.
It is comprised of a conventionally common conveying method and means, comprising rollers 2 that run on them (not shown) and a connecting part 3 that is securely connected to a conveying chain body (not shown).

Reference numerals 4 and 4 denote fixed support shafts on which a pair of substrate holders 5 and 5 are movably attached.

Reference numeral 6 denotes a board seat part provided opposite to the board holders 5, 5, on which the edge of the printed circuit board 1 is mounted.

Reference numeral 8 denotes a support shaft provided on the upper part of the board holder 5, on which a spring spring 9 is attached and a mover 10 is fitted, and a cam end 13 of an operating rod 12 is pivotally attached to the same support shaft 8 with a pivot shaft 11. is attached in contact with the movable element 10.

Reference numeral 14 denotes a press-fitting piece having a substrate holding cover portion 15 provided in conjunction with the mover 10.

shows.

Next, the operation of the above example will be explained.

As shown in the example diagram in FIG. 3, when the printed circuit board 7 is not held, the board holder 5 has the operation rod 12 upright, so the cam end 13 of the operation rod 12 is used to hold the mover 10. The movable member 10 is positioned at the uppermost position by the action of the spring 9 installed between the movable element 10 and the substrate holder 5, and the substrate holding part 15 of the holding piece 14 is pulled up. This makes it easy to place the edge of the printed circuit board 7 on the board holder 6.

After mounting the printed circuit board 7 on the circuit board holder 5 so that its edge rests on the board holder 6, as shown in FIG. The cam end 13 of the operating rod 12 uses its curve to press down the mover 10, and at the same time as the mover 10 is lowered, the board holding piece 14 is also lowered to hold the board. The printed circuit board 7 on the seat part 6 is held by the holding part 15, and the printed circuit board 7 is pressed and held on the board receiving seat part 6.

As described above, the printed circuit board 7 is held and transported, and the soldered printed circuit board 1 is transferred to the operating rod 1 by operating the operating rod 12 upright.
The movable element 10 is released from being held by the cam end 13 of No. 2, and the movable element 10 operates to pull up the board holding piece 14 by the spring spring 9.

Therefore, the board holding part 15 of the board holding piece 14 releases the grip on the printed circuit board 70 from the board seat part 6 to facilitate the removal of the printed board 7.
The holding form of the board seat part 6 in which the edge portion is placed on top allows the printed circuit board T to be easily and freely mounted and removed upward or in the sliding direction of the board seat part 6.

As described above, the printed circuit board holding and conveying holder of the present invention includes a board holder on which the edge of the printed circuit board to be held is placed, and a printed circuit board with the edge placed on the board holder. By holding the printed circuit board with a holding piece that presses the lid from above at the appropriate time, the printed circuit board can be held securely without wobbling, and it is easy to install and remove the printed circuit board. be.
