Conventional technology and its problemsConventional surface treatment of printed circuit boardsFor example, when performing nickel plating on the surface of a board with electrical connections, it was possible to conduct electricity by immersing it in each plating treatment tank sequentially and transporting it to the next tank. An operator manually holds each board one by one with a clip, and the clip is hung on a chino or other moving body that moves between various locations. Therefore, it takes time and effort to hold the printed circuit board with the clips, and if the clips are not accurately gripped to the terminals formed at the ends of the circuit board, there is a drawback that erroneous energization occurs and surface treatment cannot be performed.

Solution to the Problem This invention was created based on R:wL, and the terminal side edge of the printed circuit board with manufacturing errors. A printed circuit board alignment and rotation means configured to align the printed circuit boards one by one and rotate the printed circuit boards from the insertion position until they are clamped with clips, and after the means is moved to the clamping position,
A terminal part of a printed circuit board with a clip that lifts and lowers and opens and closes? and a clamping means designed for accurate clamping and hanging,
This allows the printed circuit board to be held completely automatically and accurately.

Example The present invention will be described below based on embodiments shown in the drawings.

In Figure IC, 1 is a script that can freely move back and forth from the position where thin plate-shaped articles such as printed circuit boards are supplied to the position where they are held and suspended by clips, and the self-propelled device 2 is mounted on this trolley 1. Alternatively, the driving means 1 provided on another frame is movable within the above-mentioned range, and furthermore, an alignment frame 8 for thin plate-like articles is rotatably supported.This alignment frame 8 is provided on both sides of the trolley l. The bearings xb and tb arranged between the frames 11 and 11 are arranged on both sides of the frame WJ.
The protruding shaft 81 is rotatably supported, and the alignment frame 8 is rotated by a drive device 4 provided on the truck 1 through the entire power transmission mechanism 5. This may be done by rotating the alignment frame 82, or alternatively by rotating the alignment frame 82 between an inclined printed circuit board feeding position and a vertical position where the printed circuit board is held and hung by clips.

Details of the alignment frame 8 are shown in FIGS. 1 and 6.

It is shown in FIG. In the illustrated embodiment, a total of 18 printed circuit boards are held by the clips in 3 columns and 6 parallels at the same time, but the number of printed circuit boards to be held is not limited to this and can be determined arbitrarily. If possible, then the first
r! The explanation will be based on 1JIC. The alignment frame 3 is cage-shaped, and is provided with fixing plates 81 at regular pitches, eight in the figure, so that the printed circuit board can be inserted accurately into the frame, and the fixing plates 81 are arranged at least on the left side so that the printed circuit board can slide smoothly. A synthetic resin board, such as a vinyl chloride board, with diamond-cut edges is used. A bracket 8 is provided inside the frame facing the fixing plate 81! Two cylinders (or inlet/4F) as and s4B are fixed in the front and back direction of the fixing plate, that is, in the vertical direction in Figure 9141, and this cylinder 88
．． A flat clamping plate 85° 861 is fixed to the tip of the rod 84, and one clamping plate 86 is equipped with belt-shaped soft synthetic resin plates or rubber plates (hereinafter referred to as rubber plates) a, qfx, or the required number of plates as shown in the figure. Arrange two sheets in parallel with a gap between them,
Further, the other clamping plate 86 is also provided with a cushioning material (for example, a sponge-like material) 811 that is softer than the rubber plate 87. A large number of the fixed plates 81 and cylinders with clamping plates are provided as a pair within the frame 8. Further, a stopper device 6 is provided on the outer side of the alignment frame 8, that is, on the upper surface in FIG. 1, and on an extension of the printed circuit board inserted along the fixing plate. This stopper device @6 supports fully rotatable shafts 62 arranged in the longitudinal direction of the alignment frame by bearings 61 protruding from the alignment frame 8, and has a swinging arm 68t protruding from the shaft 62. A stopper piece 64 is fixed to the end of this arm in a direction orthogonal to the fixed plate IM, and is connected to a cylinder 66 (or a cylinder) via a link ss'6 to this swing arm or shaft 62.
With this operation, all the stopper pieces 64 fixed to the shaft 62 are made to swing from the solid line position to the chain line position in FIG.
When this stopper piece 64 is placed in the direction perpendicular to the axis 62 at the solid line position, the end of the printed circuit board comes into contact with this stopper piece, and when the cylinder is swung to the chain line position, the fixed plate To allow a printed circuit board inserted along the line to easily come out upward. This stopper device is arranged above the entire fixed plate.

Operation The operation of the apparatus configured as described above will be explained below.

The cart 1 is stopped at the printed circuit board supply position, and the alignment case 8 is stopped at the position indicated by the chain line in FIG. 3 with the stopper device tilted downward. Is the worker at the terminal side of the printed circuit board? When the printed circuit board is inserted along each fixing plate 81 so that the printed circuit board is facing forward, it slides down along the fixing plate 81 due to its own weight, and stops when it comes into contact with the stopper piece. When the printed circuit boards are fed along all the fixing plates, the two cylinders 88 and 84 are actuated, and the eight rubber plates and the cushioning material B8 move forward and clamp them together with the fixing plates. In this state, rotate the alignment case so that the printed circuit board is in a vertical position with its terminal side facing upward, and stop the case. Move it to the full clamping position. At this time, it is also possible to rotate the alignment case and move the cart at the same time.

In the clamping device, a clip 1 fixed to the lifting frame descends to clamp the terminal portion of the printed circuit board, but at this time, the clips are arranged so that one clip faces each printed circuit board. There is. When this clip is lowered, it is in the open state and the tip of the printed circuit board comes into contact with a part of the clip, but at this time, by pushing down the clip a little on the printed circuit board, the printed circuit board is held by this clip at the end of the board. The cylinder with the cushioning material 88 is designed to be clamped and released from the fixing plate before the printed circuit board is clamped, and when the board receives a downward force from the clip, the rubber plate bends a little due to its elasticity, but the printed circuit board is not clamped. The entire state of the printed circuit board is maintained, the edges of the printed circuit board are accurately aligned, and the clips are used to hold the printed circuit board. When or before the printed circuit board is held by the clips, the stopper piece is tilted by the cylinder to the position indicated by the chain line in FIG. 1, and when the clips are raised, the printed circuit board is held and suspended. Thereafter, the script is returned to its original supply position, the alignment frame is returned to its original tilted state, and this operation is repeated.

Effects of the Invention According to the present invention, is the printed circuit board tilted and along the fixed plate? That terminal side? Just by inserting it in a downward direction, it is aligned accurately and is automatically and accurately clamped by the clip that opens and closes up and down, so the printed circuit board can be clamped to the clip automatically, improving efficiency and making it possible to accurately align the board. Since the terminal portions are clamped, there are advantages such as the desired surface treatment can be reliably performed without failure to conduct electricity.
