Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a device for automatically inserting components into a printed circuit board, which has a simple, quick and accurate structure for automatically supplying a printed circuit board and automatically taking out a printed circuit board into which components have been inserted. This invention relates to a printed circuit board attachment/detachment device that can be used to attach and detach printed circuit boards.

Generally, the time required for inserting and correcting components per printed circuit board using an automatic component inserter is 20 to 80 seconds.

Therefore, in order to increase the operating efficiency of the automatic component insertion machine, it is necessary to shorten the time required to supply and take out printed circuit boards as much as possible, and various printed circuit board supply devices have been proposed for this purpose.

A device for supplying and discharging printed circuit boards for a conventional automatic component insertion machine has a part of a printed circuit board supply hopper, an automatic component insertion machine (table), and a printed circuit board ejection section with inserted components arranged in a straight line, and each part is A configuration is used in which the printed circuit board is connected by a guide rail and the printed circuit board is transferred on the rail.

In addition, instead of transferring the printed circuit board by the guide rail, a set of chucks that move horizontally and vertically are provided, and a part of the printed circuit board in the hopper is held by the chuck,
It moves horizontally to the work table of the automatic parts insertion machine and supplies it.

Next, the printed circuit board into which the components have been inserted is held, moved horizontally to the receiving section for the next process, and discharged.

After the printed circuit board has been discharged, it returns to a part of the hopper in preparation for supplying the next printed circuit board, or two sets of chucks are installed in parallel, one set of chucks holds the printed circuit board in a part of the hopper, The other set of chucks simultaneously holds the printed circuit board with components inserted on the work table of the automatic component insertion machine, moves horizontally, and transfers the printed circuit board onto the work table of the automatic component insertion machine after the components have been inserted. The printed circuit board is simultaneously transferred to a receiving section for the next process, and when the operation is completed, it is moved horizontally and returned to its original position in preparation for the next supply operation.

However, in the former configuration in which printed circuit boards are fed by guide rails, if the printed circuit boards are moved at high speeds, distortion occurs due to the resistance difference or dimensional gap between the guide rails and the printed circuit boards, so it can only be transferred and fed at low speeds. For printed circuit boards with large dimensions, the transport distance is long,
For this reason, there was a drawback that it took 6 to 8 seconds to stop the machine for supplying printed circuit boards and discharging printed circuit boards with inserted components.

Furthermore, it is necessary to provide a movable notch in the positioning mechanism for the printed circuit board, which makes the structure unreasonable due to space constraints on the machine, and is not applicable to dual-type automatic component insertion machines with component insertion sections arranged side by side. There were drawbacks.

In the latter configuration, in which the printed circuit board is held by one or two sets of chucks and the printed circuit board is fed by moving linearly or rotationally in the horizontal direction, large mass components such as a chuck opening device and a vertical movement device are used. It is very difficult to move the machine at high speed and stop it at a predetermined position in a short time, and it is necessary to stop the machine for 7 to 9 seconds to feed and eject printed circuit boards.

In addition, the structure became large, which caused problems in terms of operation and maintenance.

The present invention was obtained as a result of studies aimed at solving the drawbacks of the conventional printed circuit board attachment/detachment device as described above.

That is, in the present invention, at least two printed circuit board mounting frames are mounted on the upper surface of a rotatable table that can move in two axes perpendicular to each other when viewed from above, and the printed circuit board is mounted above the table. An automatic component insertion machine for inserting components into the board and a printed circuit board chuck mechanism are installed, and the chuck mechanism is attached to a frame that can move up and down in the direction of mounting the printed circuit board, and when it descends, it clamps the printed circuit board with no components inserted. A printed circuit board mounting/dismounting device comprising a supply chuck and a take-out chuck, which simultaneously release the printed circuit board from one printed circuit board mounting frame and clamp a printed circuit board with a component inserted that is fixed to the other printed circuit board mounting frame. It provides:
