Description

  In the present invention, a clamping jig that is guided and moved while being in sliding contact with a power supply rail holds the end of a strip-like thin plate-like workpiece such as a printed circuit board, and horizontally or vertically moves the plating processing liquid in the conveyance path. It is a transport type continuous plating device that continuously conveys in the horizontal direction in the posture and performs electrolytic plating treatment on the surface of the thin plate-like workpiece to be fed from the clamp jig in this transport path. It provides a grease supply system that can stably and reliably supply an appropriate amount of grease to the rail position where the grease application work is dangerous and difficult so that stable feeding can be performed to the clamp jig. is there.

  Regarding the horizontal conveyance type continuous plating apparatus using clamp conveyance, the present applicant can surely and smoothly perform automatic opening and closing of a clamping chuck (clamp jig) that horizontally conveys the both side edges of a plate-like workpiece. An apparatus for conveying a plate-like workpiece in a surface treatment apparatus has been proposed (Patent Document 1). The transport device disclosed in Patent Document 1 includes guide rails 15 each having a rectangular cross section for guiding a clamping chuck group (clamp jig) that moves in a linear drive path portion on the transport path side. It functions as a power supply rail that supplies a cathode current to an object to be processed conveyed via a chuck (clamp jig).

  In order to accurately transport a printed circuit board horizontally with a clamp jig attached to a belt that rotates in an endless manner, it is important that the clamp jig that moves along the conveyance path runs stably without shaking. As a means for stabilizing the movement of the clamping jig, a clamping jig having a rectangular guide rail 15 arranged in parallel with the conveying path as in the conveying apparatus of Patent Document 1 and moving the conveying path The guide rail 15 is guided and moved while being in sliding contact with the guide rail 15. Moreover, in patent document 1, this guide rail 15 is made to function as a feed rail. In the case of a clamp power supply method in which power is supplied from the guide rail (power supply rail) to the printed circuit board via a clamping chuck (clamp), it is important to stabilize power supply from the guide rail 15 (power supply rail) to the clamp jig. It is.

  For this reason, the work site regularly applies grease to the surface of the guide rail having a rectangular cross section, and the clamping chuck (clamp jig) slides smoothly along the rail surface of the guide rail to which the grease has been applied. It is guided while in contact so that it can move in the transport direction.

  However, especially during the operation of the plating apparatus, a large number of clamping chucks (clamp jigs) frequently travel along the guide rail, so that it is extremely difficult to apply an appropriate amount of grease to a desired position of the guide rail. And dangerous. For this reason, the operation of the plating apparatus must be stopped during the grease application operation to apply grease to the guide rail. Even when the operation of the plating equipment is stopped, the grease application location on the guide rail is complicated and narrowed by various equipment including a number of clamp jigs attached to the endless belt. The operation of applying an appropriate amount of grease is difficult.

  Moreover, several patent documents of the present applicant are disclosed about the vertical conveyance type continuous plating apparatus (for example, Patent Documents 2 to 4). This vertical conveyance type continuous plating apparatus is a hanger jig supported by a horizontally-distributed rectangular feed rail that functions as a horizontally disposed cathode bar (this hanger jig has a thin plate-like product below it). A plurality of clamps that can hold the upper part of the product in a suspended state are provided.) The product upper part of a thin plate product such as a printed circuit board to be plated is held in a suspended state and suspended by the hanger jig. Further, while feeding the thin plate product from the power supply rail to the upper part of the product through the hanger jig, the plate surface of the thin plate product is horizontally disposed in the plating solution in the plating tank along the power supply rail. It is an apparatus that performs electroplating while continuously transporting in a lateral orientation parallel to the transport direction.

  Even in this vertical conveyance type continuous plating apparatus, the grease application work to the power supply rail where the hanger jig is frequently moved has the same problems as those described in the horizontal conveyance type continuous plating apparatus by the clamp conveyance described above. .

The grease discharge port 20a of the device 20 is communicated through a flexible grease supply tube 22 whose pipe line can be changed, and is injected from the grease injection device 20 through the grease supply tube 22 into the grease injection port 15a. The grease G supplied from the inlet 15a into the grease storage groove 15 gradually overflows from the grease outlet 15b above the rail upper surface. The 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 that moves through the position.

  In FIG. 4, the grease storage groove 15 is formed at one place on the substrate carry-in side of the power supply rail 8, but may be a plurality of places spaced in the length direction of the power supply rail 8.

  The other characteristics of the grease supply system of the vertical conveyance type continuous plating apparatus are substantially the same as the characteristics of the grease supply system of the horizontal conveyance type continuous plating apparatus already described, and thus redundant description is omitted.
