In this state, the table 2 is rotated at about 90 deg. with a cylinder 5 around an axis 6a in the direction A and the base plate 1 is regulated to a vertical state and made adjacent to the inside of an auxiliary electrode frame 20 in the case of plating and the lower end of the base plate is fitted to plural groove members 24 on the lower frame part 23 of the frame 20 and the base plate is set to a jig. In this case, the base plate 1 is supported with a back receiving bracket 9 which is progressed in the direction B and furthermore the upper end of the base plate 1 is clamped with a mechanism 10. When the table 2 is returned to the original position, the stopper 3 is pulled to the inside of the face 2a. Thereby the stopper 3 does not interface with the base plate 1 and the frame 20, etc.

Description

[Detailed Description of the Invention] [Summary] A framed plating jig is used as an auxiliary pole when it is necessary to plate the board uniformly, such as when plating through holes on a printed wiring board. Regarding the loading device that supplies substrates to such framed plating jigs, it has a simple mechanism that automatically avoids these auxiliary poles even for plating jigs with auxiliary poles around the substrate. The purpose of the inversion table is to make it possible to load a substrate, and the inversion table has a substrate support surface and a stopper that can be inserted into and taken out from the substrate support surface, and the substrate is loaded while the lower end of the substrate is supported by the stopper. When changing from a horizontal or tilted state to a vertical state, setting the board inside the auxiliary pole frame in the vertical state, and returning the reversing table to its original position, move the stopper away from the substrate support surface of the reversing table. To configure a loading device for a substrate onto a frame-equipped plating jig that can be retracted.

[Industrial application field]

The present invention relates to a loading device that supplies a substrate to a plating processing section. In particular, a framed plating jig is used as an auxiliary pole when it is necessary to plate the board uniformly, such as when performing through-hole plating on a printed wiring board. The present invention relates to a loading device that supplies a substrate to a plating jig.

[Conventional technology]

When plating a flat member such as a printed circuit board, the thickness of the plating tends to be thicker at the periphery of the surface of the board than at the center. When precision in plating thickness is not required, the plating jig does not require an auxiliary pole, and therefore there are no obstacles such as frames around the plating jig, making automatic loading relatively easy.

However, with conventional plating equipment without such auxiliary electrodes, the plating thickness on the surface of the printed board varies, and as in the case of through-hole plating, precision in plating thickness is required to cope with higher density. could not be used if In the case of a plating apparatus that uses an auxiliary electrode, the substrate must be loaded onto the plating jig while avoiding the auxiliary electrode, but automation in such cases has been difficult in the past.

[Problem to be solved by the invention]

Therefore, the present invention provides a frame-mounted plating method for substrates that can be loaded with a simple mechanism and automatically avoiding these auxiliary poles, even for plating jigs with auxiliary poles around the substrate. The purpose is to provide a loading device for a jig.

[Means to solve the problem]

In order to solve this problem, the present invention has a frame that defines an auxiliary pole in a vertical plane when plating a substrate, and groove members that receive the lower end of the substrate are placed at intervals in the lower frame part of the frame. A loading device that sets a substrate on a plating jig that can be attached to a plurality of substrates, has a substrate support surface and a stopper that can be inserted into and taken out from the substrate support surface, and supports the substrate horizontally or horizontally while supporting the lower end of the substrate with the stopper. from the inclined state to the vertical state, and in the vertical state, the lower end of the substrate fits into the groove member,
and an inversion table that rotates around a predetermined axis and is set such that the substrate is located adjacent to the auxiliary pole frame in the vertical plane inside the auxiliary pole frame, and the substrate is in a vertical state. a back support bracket for supporting the opposite surface of the reversing table; a clamping mechanism for clamping the upper end of the vertical substrate; and a stopper driving means for retracting the stopper inward from the substrate supporting surface of the reversing table after clamping. A device for loading a substrate onto a framed plating jig is provided.

[For production]

In the present invention, in the process of inverting the board by the reversing table and installing it in the auxiliary pole frame, the stoppers protrude toward the board support surface and support the bottom edge of the board, and after the board is clamped, the stoppers Since the stopper is pulled into the inside of the substrate support surface, when the reversing table returns to its original position, the stopper does not interfere with the groove member of the substrate and auxiliary pole frame. Automatic loading is possible.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a principle diagram of the loading device of the present invention, Fig. 2 is a configuration diagram of an embodiment of the loading device of the present invention, Fig. 3 is a perspective view of an auxiliary pole and a stopper, and Fig. 4 is a diagram of Fig. 2 FIG. 5 is an enlarged detailed view of the stopper, showing the state of the substrate after loading as seen from the arrow (■) in FIG. 1.

In these figures, substrates 1 such as printed boards are sequentially placed on a substrate support surface 2a of a horizontal inversion table 2 (phantom line in FIG. 1) by means not shown. A stopper 3 driven by a cylinder 4 is attached to the reversing table 2 so that it can be moved in and out of the substrate support surface 2a. At this time, the stopper 3 protrudes above the substrate support surface 2a of the reversing table 2 and is in contact with the lower end (right end) of the substrate 1. The reversing table 2 itself is connected to the shaft 6 by the cylinder 5.
It is attached to the cylinder arm 6, which is rotated around a, so as to be slidable back and forth. The power cylinder 7 (FIG. 2) is for sliding the reversing table 2 with respect to the cylinder arm 6.

After the reversing table 2 is pulled backwards (to the right in the figure) while horizontally supporting the substrate 1, it is rotated approximately 90 degrees in the direction of the arrow 6 about the shaft 6a by the cylinder 5 together with the cylinder arm 6.
The substrate 1 is rotated once to bring the substrate 1 into a vertical position. During this time, board 1
The lower end of is supported by a stopper 3.

The substrate 1 in the vertical state is located adjacent to the inside of the frame 20 that forms an auxiliary pole during plating.

As shown in FIG. 5, this auxiliary pole frame 20 includes an upper frame 21
It consists of a vertical horizontal frame part 22 suspended from a horizontal frame part 22 and a horizontal lower frame part 23, and a plurality of groove members 24 for receiving the lower end of the board 1 are attached to the lower frame part 23 at intervals. Therefore, in the vertical state, the lower end of the substrate 1 enters the V-shaped groove of the groove member 24, and there is a slight gap between it and the lower frame portion 23. Further, there is a slight distance between the horizontal ends of the plurality of substrates 1 arranged horizontally with adjacent substrates 1 and between the horizontal bar portions 22.

The surface of the substrate 1 in the vertical state opposite to the reversing table 2 is supported by a back support bracket 9 that is moved forward in the direction of arrow B (to the left in the figure) by a cylinder 8. Board 1
Above is a clamp 10 which is opened and closed by left and right cylinders 11, 12 to clamp the top edge of the substrate. The upper end of the substrate 1 in the vertical state is clamped by the clamp 10 that descends in the open state, and after the substrate 1 is released from the reversing table 2 and the back support bracket 9, it is lifted together with the auxiliary pole frame 20 by the lifting device 30. It is transported to a plating device (not shown). Note that the clamp 10 also functions to supply power to the substrate 1 during plating.

In FIG. 2, reference numeral 7 is a power cylinder that slides the reversing table 2 with respect to the cylinder arm 6, and 15 is a lower frame of the apparatus. Other details are the same as in FIG.

In FIGS. 3 and 4, a cylinder 4 that holds a stopper 3 is attached to the reversing table 2 via a bracket 4c, and a plate 4b extending laterally is attached to the tip of the cylinder 40 rod 4a. 3 are arranged at intervals on the plate 4b so as not to interfere with the groove member 24 of the auxiliary pole 20. When the stopper 3 is moved by the cylinder 4 in the direction of arrow C in FIG. 3, it can protrude above the substrate support surface 2a of the reversing table 20 (FIG. 1) and support the lower end of the substrate 1 (as shown by the solid line in FIG. 4). position). Furthermore, by being pulled in the direction opposite to arrow C, it enters inside the substrate support surface 2a of the reversing table 2 (the imaginary line position in FIG. 4).

FIG. 6 shows the operation of such a stopper 3. FIG. 6(a) shows the process of reversing the reversing table 20, at which time the substrate 1 is attached to the shaft 6 of the cylinder arm 6 (FIG. 1).
Move in the direction of the arrow with a as the center, and the bottom end will be at stopper 3.
The groove member 24 of the auxiliary bottom frame 23 remains supported by the
to go into. FIG. 6(b) shows the state immediately after the lower end of the substrate 1 enters the groove member 24. FIG. FIG. 6(C) shows a state in which the stopper 3 is retracted in the direction of arrow E after the lower end of the substrate 1 enters the groove member 24. With the stopper 3 retracted in this manner, the reversing table 2 is returned together with the stopper 3 in the opposite direction of the arrow around the shaft 6a, so the stopper 3 no longer interferes with the substrate 1.

FIG. 7 is a time chart showing the operation of the main components of the automatic loading device of the present invention. Before the reversing table 2 performs the reversing operation, the back support bracket 9 moves forward from the cylinder 8 in the direction of arrow B in FIG. 1 to a position where it supports the back surface of the substrate. Upon receiving an instruction to complete the forward movement of the back support bracket 9, the inversion table 2 performs an inversion operation, and the substrate 1 is held in a vertical state by the back support bracket 9 and the inversion table 2 from both sides. Upon receiving an instruction to complete the inversion of the inversion table 2, the elevating lift 30 is lowered.

At this time, the clamp 10 is in an open state.

Upon receiving an instruction that the lifting lift 30 has completed its descent to a predetermined position, the cylinders 11 and 12 move away from each other to close the clamp 10 and clamp the upper end of the substrate 1. At the same time, the stopper 3 starts moving backward. When it is confirmed that the stopper 3 has completed its backward movement and has been retracted into the inside of the inversion table 20 substrate support surface 2a, and the clamping operation of the clamp 1O is completed, the back support bracket 9 and the inversion table 2 are returned to their original positions. 30 starts to return to its original position, and the elevating/lowering riff 30 starts to rise.

When it is confirmed that the reversing table 2 has returned to its original position, the stopper 3 moves forward onto the reversing table 2, a new substrate 1 is supplied onto the reversing table 2, and the next cycle is started. Ru.

〔Effect of the invention〕

As explained above, in the present invention, the substrate 1 is inverted about the predetermined axis 6a by the inversion table 2, and the auxiliary pole frame 2
0, the stopper 3 is placed on the substrate support surface 2a.
The stopper 2 protrudes upward and supports the lower end of the substrate, and when the reversing table 2 returns to its original position around the predetermined axis 6a, the stopper 2 is retracted into the inside of the substrate support surface 2a. There is no interference with the substrate 1, the auxiliary pole frame 20, etc., and therefore automatic loading is possible with a simple structure even in a plating jig that uses the auxiliary pole frame 20 to obtain uniform plating thickness. becomes.

Thereby, the accuracy of plating thickness can be improved using a plating apparatus with a simple structure.
