Description

Grease supply system of conveying continuous plating equipment {GREASE SUPPLYING SYSTEM OF TRANSPORT TYPE CONTINUOUS ELECTROPLATING APPARATUS}

The present invention is a clamp jig that is guided and moved while sliding in contact with a feed rail to hold an end portion of a strip-shaped thin workpiece such as a printed board so that the plating liquid in the conveying passage is continuously horizontally or vertically in a horizontal posture or a vertical posture. It is a conveyance type continuous plating apparatus which conveys and performs electroplating treatment on the surface of the thin-plate-shaped object to be fed from the clamp jig in this conveyance passage, and stabilizes the running of the clamp jig in a conveyance passage, and is stable to a clamp jig. It is to provide a grease supply system that can supply a proper amount of grease completely and reliably to a rail position where grease application is dangerous and difficult to feed.

In the horizontal conveyance type continuous plating apparatus by clamp conveyance, the present applicant has secured and smoothly performed the automatic opening and closing of the clamping chuck (clamp jig) which horizontally conveys by clamping both side edges of a plate-shaped to-be-processed object. The conveying apparatus of the plate-shaped to-be-processed object in an apparatus is proposed (patent document 1). In the conveying apparatus of this patent document 1, the guide rail 15 of the cross-sectional rectangular shape which guides the clamping chuck | zipper group (clamp jig) which moves the linear drive path part on the conveyance path side is respectively provided, and this guide rail 15 is clamped. It functions as a feed rail which feeds current of a cathode to the to-be-processed object conveyed through a chuck (clamp jig).

In order to accurately horizontally convey the printed circuit board with the clamp jig attached to the belt which rotates endlessly, it is important to stably run the clamp jig moving the conveyance passage so as not to shake, and to stabilize the movement of the clamp jig moving the conveyance passage. As a means, the guide rail 15 of the cross-sectional rectangular shape arrange | positioned in parallel with a conveyance passage like the conveyance apparatus of patent document 1 is provided, and the clamp jig which moves a conveyance passage guides while sliding-contacting this guide rail 15. It is supposed to move. Moreover, in patent document 1, this guide rail 15 is functioning as a power supply rail. In the case of the clamp feeding system that feeds the printed circuit board from the guide rail (feeding rail) via the clamping chuck (clamp), it is important to stabilize feeding from the guide rail 15 (feeding rail) to the clamp jig.

For this reason, at the work site, grease is regularly applied to the surface of the guide rail having a rectangular cross section, and the pinching chuck (clamp jig) is guided while sliding smoothly along the rail surface of the guide rail to which grease is applied. It can be moved in a conveyance direction.

However, since a large number of pinching chucks (clamp jigs) travel and move frequently along the guide rails, especially during the operation of the plating apparatus, applying an appropriate amount of grease to a desired position of this guide rail is very difficult and dangerous. . For this reason, the operation operation | movement of a plating apparatus should be stopped between the grease application | work which is going to apply grease to a guide rail. In addition, even when the plating apparatus is stopped, the grease application point of the guide rail is narrowly arranged and narrowed by various equipments including a plurality of clamp jigs attached to the endless belt, so that a suitable amount of grease is applied to a desired position of the guide rail. Applying is difficult.

Moreover, about the vertical transfer type continuous plating apparatus, several patent documents of this applicant are disclosed (for example, patent documents 2-4). This vertical conveying continuous plating apparatus is a hanger jig freely supported by the horizontal movement on a feed rail having a rectangular cross section functioning as a cathode bar arranged horizontally (the hanger jig suspending the upper part of a thin product in a lower part thereof). And a plurality of clamps which can be clamped in a state.) The upper part of a thin product such as a printed board to be plated is clamped in a suspended state, and the thin plate product is suspended in a suspended state by the hanger jig. Is fed from the feed rail through the hanger jig to the upper part of the product, while conveying the plating solution in the plating tank along the feed rail in a horizontal direction while continuously conveying the plate surface of the thin plate-like product in a horizontal posture parallel to the conveying direction. It is a device for plating.

In this vertical transfer type continuous plating apparatus, about grease application | work to the feeder rail to which a hanger jig is frequently moved, there exists the same damage as the above-mentioned damage in the horizontal transfer type continuous plating apparatus by clamp conveyance.

Although redundant, the main configuration of the grease supply system is described.

As shown in Figs. 4, 5 and 3, the grease supply system has a grease storage groove in which a grease outlet 15b is opened on an upper surface of the feed rail 8 at a position on the substrate carrying-in side of the feed rail 8 ( 15, a grease injection port 15a communicating with the grease storage groove 15 is formed in the open side portion 8c of the feed rail 8, and the grease injection port 15a of the feed rail 8 is formed. ) And the grease discharge port 20a of the grease injection mechanism 20 arranged in a remote location that is safe and easy to operate are communicated through the flexible grease supply pipe 22 that can change the pipe line. 20 is injected from the grease inlet 15a into the grease inlet 15a through the grease supply pipe 22, and the grease G supplied from the grease inlet 15a into the grease storage groove 15 is railed from the grease outlet 15b. It overflows slowly from the top It is registered. Grease supplied to the upper surface of the power supply rail 8 is transmitted from the upper surface of the rail to both sides of the rail by the clamp jig 4 moving through this position.

In FIG. 4, although the formation location of the grease storage groove 15 is made into one place of the board | substrate carrying-in side of the feeder rail 8, you may make it into several places spaced apart in the longitudinal direction of the feeder rail 8. As shown in FIG.

Since other characteristics of the grease supply system of the vertical transfer type continuous plating process apparatus are substantially the same as the characteristics of the grease supply system of the horizontal transfer type continuous plating process apparatus described above, overlapping description is abbreviate | omitted.
