Description

  The present invention provides a plating apparatus in which the transfer rail is suspended and supported via a product hanger, and is formed into a thin plate shape such as a printed wiring board that is put into the treatment liquid of the front and rear treatment liquid and the plating treatment liquid in each tank. The present invention relates to a product guide device for filling in liquid that can reliably guide the hanging posture of a product.

  The plating apparatus includes a pretreatment unit that pre-treats a product to be plated by degreasing and washing with water, a plating treatment unit that plates the pre-treated product, and a plating product after further washing with water and hot water. A post-processing unit for processing is provided. As the pre-processing unit and the post-processing unit, those having a schematic configuration (a configuration in which the product guide device for submerged charging according to the present invention is removed from FIG. 1) are publicly known (for example, Japanese Patent No. 2943070). ). As shown in FIG. 1, a plurality of pretreatment liquid tanks 1 arranged in a line in the horizontal direction are arranged in the pretreatment part A, and a plurality of posttreatment liquids arranged in a line in the horizontal direction are arranged in the posttreatment part B. A tank 2 is arranged. At a position above the plurality of pretreatment liquid tanks 1, a pretreatment transfer rail 3 </ b> A that is moved up and down in a horizontal state between the rising position and the descent position at the upper position is provided. At the upper position, a post-processing transfer rail 3B that is moved up and down in a horizontal state between the raised position and the lowered position at the upper position is provided. A plurality of product hangers 4 for hanging and supporting the product W to be plated are supported on these transfer rails 3 so as to be freely transferred along the rails. When a thin plate product W such as a printed wiring board is suspended and supported by the product hanger, the product hanger is suspended by grasping the upper position of the product so that the plate surface of the product is in a suspended posture parallel to the rail track. I support it. These product hangers 4 are engaged with the hanger feeding means (pushing pusher) 5 at the raised position of the transfer rail 3 and transferred in one direction (left direction in FIG. 1) along the transfer rail. Are sequentially transferred to the product entry position corresponding to Then, the product W suspended and supported by the product hanger 4 transferred to the product input position S is supplied into the processing liquid tanks 1 and 2 at the lowered position of the transfer rail 3, and is supplied into the processing liquid. The product is pre-processed or post-processed as necessary. Thereafter, the transfer rail 3 is returned to the raised position, and the product hanger 4 and the product W supported by the transfer rail 3 returned to the raised position are transferred to the product loading position S of the next treatment liquid tank at the raised position. It is transported along the rail by the hanger feeding means (pushing pusher). In this manner, the products suspended and supported on the transfer rails that are moved up and down via the product hangers are sequentially put into the respective treatment liquid tanks, and pre-processing and post-processing are performed.

  Further, as the plating processing section, a schematic configuration (a configuration excluding the submerged product guide device of the present invention from FIG. 2) shown in FIG. 2 is known (for example, Japanese Patent No. 2943070). . The plating processing section shown in FIG. 2 has a product charging section 6A on one end side of a long tank plating processing liquid tank 6, and an upper position of the product charging section 6A has an ascending position and a descending position at the upper position. Transfer rail 3 that is moved up and down in a horizontal state (this transfer rail may be the transfer rail 3C for product introduction shown in FIG. 2, and for example, as shown in FIG. 1 of Japanese Patent No. 2943070 The rear end side of the pretreatment transfer rail may be extended to the position of the product input portion. At the raised position of the transfer rail 3, the product hanger 4 is transferred from the transfer rail 7 of the product transfer portion aligned with the transfer rail 3 to the product input position S of the transfer rail 3. The product W suspended and supported by the product hanger 4 transferred to the product input position S of the transfer rail 3 is input to the product input unit 6A in the plating solution tank 6 at the lowered position of the transfer rail 3. The product W introduced into the processing liquid of the product input unit 6A is transferred from the transfer rail 3 placed at the lowered position to the plating processing transfer rail 8 aligned with the transfer rail (this plating processing transfer rail is always The product transferred to the plating treatment rail 8 is moved to the plating treatment rail 8 by the conveying means provided along the plating treatment rail. The plate is processed while being slowly conveyed along the surface.

In such a plating apparatus having a front-rear processing unit and a plating processing unit, suspension of thin plate products such as printed wiring boards that are put in the processing liquid of each processing liquid tank and supported in a suspended position on product hangers. As a product guide device for submerging the liquid in which the posture can be reliably guided, a device in which this guide device is attached to a transfer rail in which a product hanger is suspended and supported so as to be transportable has not been developed.

  On the other hand, as a product guide device developed by the present inventor, a device developed for a product transfer device for a plating apparatus has already been patented (Japanese Patent No. 3297426). The product guide device in this product transfer device is, in short, attached to the transfer rail of the product transfer device, and is an open position for receiving the sheet-like product on the transfer rail and a closure that prevents the received sheet-like product from shaking. Each guide member can be controlled to be opened and closed with respect to both sheet surfaces of the sheet-like product at a position, and the guide member has a substantially C-shape for receiving the sheet-like product in the transfer rail. The lower side is pivoted to be openable and closable with respect to both sheet surfaces of the sheet-like product with the upper side of each guide member as a fulcrum to the open position and the closed position for preventing the received sheet-like product from shaking. The upper side of each guide member is pivoted on the rail for transfer, and the lower side is pivoted so as to be freely opened and closed.

However, in this product guide device developed for the product transfer device of the plating device, the lower side is pivotably opened and closed with respect to both sheet surfaces of the sheet-like product with the upper side of each guide member as a fulcrum. Since the upper side of each guide member is pivotally mounted on the transfer rail, the jig (product hanger) and the sheet-like product received by the transfer rail are passed through the mounting position of the guide member. It could not be transported first along the rail for transfer, and there was no need to transport it. In addition, as described above, this product guide device is configured such that the upper side of each guide member is pivoted so that the lower side can be opened and closed with respect to both sheet surfaces of the sheet-like product. For this reason, when adjusting the closing position, that is, when adjusting the distance between the guide members relative to the two sheet surfaces at the closing position, there is a problem in that the guide members cannot be controlled to the same vertical closing position with respect to the two sheet surfaces. Similarly, in the open position, the lower side of each guide member is widened to the left and right as compared with the upper position.
