Abstract

PURPOSE:To surely support a lead frame and to perform plating treatment by protruding a couple of side walls in right and left which are narrow in central parts and have intervals gradually broadening toward both ends on a supporting arm, pressing and holding the lead frame from the upper part with an electroconductive piece in the central parts of these side walls. CONSTITUTION:Only an electroconductive arm 16 is held up to the upper part in a position feeding a lead frame, and the lead frame 50 is introduced between a couple of side walls 11 in right and left which are protruded to the upper face of a supporting arm 10 and are narrow in the central parts and gradually broad in the interval toward both ends. Then the electroconductive arm 16 is descended, the upper end face 52 of the lead frame 50 is pressed with reverse V-shaped electroconductive pieces 15 of the tip thereof in the central parts of the side walls 11, and the lead frame 50 is surely held. The electroconductive arm 16 is intermittently advanced into a plating tank 1 together with the supporting arm 10 by driving a conveyor chain 3 and plating treatment of the lead frame 50 is performed via the electroconductive pieces 15. Thereby all parts of the lead frame 50 can be uniformly plated.

(Prior Art) As shown in the above-mentioned lead frame plating apparatus, for example, as shown in Japanese Unexamined Patent Application Publication No. 61-879 (No. A device is known in which a swinging arm is provided, a groove having a V-shaped cross section is provided on the upper surface, and a cathode contact portion is formed at the inner bottom of the groove.In such a conventional device, The lead frame to be plated is V
It is dropped into the inside of the letter-shaped groove and comes into contact with the cathode contact part, where it receives electricity for plating.
Since the lead frame and cathode contact portion are only in contact due to the lead frame's own weight, the power supply becomes unstable, especially when subjected to buoyancy in liquid.
There was a risk that uniform plating would not be achieved.

In addition, lead frames are plated in the form of a long, thin plate with multiple pieces connected to each other, but some of them are curved, so if you measure the width of the groove, the curved lead frame will fall into the groove. If the lead frame is not inserted securely and the width of the groove is widened, the uncurved lead frame will wobble inside the groove, and in any case, reliable conduction will not be possible, resulting in uneven plating. There was a problem that this was not done.

It is supported by the pillar (8) so as to be able to rise and fall independently of the support arm αO), and the energizing arm (16) can be moved up and down parallel to the upper end of the lead frame (5o). The current carrying piece (15) is connected to the support arm (101) by the lead wire (19).
It is connected to the current-carrying part (2o) of. Also, this current-carrying part (
The lower surface of 2o) is always in contact with the upper surface of a lifting rail (21) protruding from the side surface of the machine frame (2). Lifting rail (2
1) has the role of pushing up the support arm (10) to the position shown by the imaginary line in FIG.
It has the role of flowing plating current to the negative power source via the current-carrying part (20). Furthermore, at the supply and take-out positions shown in FIG. 5, a removal rail (22) that engages with the - side of the parallel link (18) supporting the current-carrying arm (16) is provided as shown in FIG. , the current-carrying arm (16) can be lifted independently of the support arm (10).

In this way the lead frame (5o) is supported IIs
(If the conhair chain (3) is driven after being securely supported between the upper side walls (11) and (11) of 1G+,
The support arm α0) is connected to the plating tank (1) together with the current-carrying arm (16).
The lead frames 1 and (50) are energized via the current-carrying piece (15) while intermittently progressing inside the lead frame (5o), and the lead frame (5o) is plated. At this time, even if buoyancy occurs in the lead frame (50), the upper end of the lead frame (5o) is pressed by the current carrying piece (15) with a much stronger force, so the power supply may become unstable. Therefore, the entire lead frame (50) is uniformly plated.
