Description

  The present invention relates to a work hanger that supports a rectangular substrate product such as a printed circuit board to be plated and suspended on a cathode bar so as to be movable in a vertical state. As a work hanger in electroplating equipment by vertical transport plating that can plate and support the substrate product at the optimal suspension support position, especially plating processing while continuously transporting thin substrate products in liquid in the horizontal direction The present invention relates to a suitable work hanger.

  As a conventional work hanger used in an electroplating apparatus for plating a rectangular substrate product such as a printed circuit board, for example, there is a work hanger provided by the present applicant in Utility Model Registration No. 3085849 or Japanese Patent Application Laid-Open No. 2003-328193. Are known. This work hanger has a support member having both a support function that is suspended and supported by a cathode bar so as to be laterally movable, and a contact function that is conductively connected to the cathode bar, and is integrated with the support member at a lower portion of the support member. A horizontally long substrate that is configured in a fixed manner or is fixed in surface contact so as to be conductively connected to the lower portion of the support member, and extends along the direction of the horizontally long side of the substrate product, and the horizontally long substrate And a plurality of clamping clamps (clamping clips) that hold the upper part of the substrate product and support the substrate product in a suspended state. The substrate product is energized from the cathode bar via the work hanger.

  A rectangular substrate product suspended and supported by a number of the work hangers that are continuously transferred along the cathode bar by an appropriate conveyor means is a so-called vertical continuous conveyance plating method known from Japanese Patent No. 2943070. Thus, the plating process is carried out while being continuously conveyed in the plating solution in a side-by-side state. In this vertical continuous conveyance plating method, each work hanger is used to prevent the current from concentrating on the end of the product in the width direction and to increase the plating thickness and to make the plating thickness of the entire product uniform. Then, the plating process is carried out while continuously transporting the plating solution in a side-by-side serial state with a slight gap between the products in the transport direction of each substrate product supported by being suspended.

  In the case of this vertical continuous conveyance plating, in order to make the plating thickness uniform, a slight gap is provided between a large number of substrate products conveyed continuously as described above. For this reason, the horizontal size of the work hanger that supports the substrate product in a vertical state (in the above-described conventional example, the horizontal size of the horizontal substrate for mounting a plurality of clamping clamps) is supported in a vertical state by the hanger. The rectangular substrate product is configured to be smaller than the horizontally long size. In addition, these work hangers are generally used regardless of the size of the substrate product, and thus are configured for a substrate product having a small width. This is because when a substrate product with a relatively small width is suspended and supported using a work hanger matched to a substrate product with a large width size, the horizontally long substrates of large hangers collide with each other, and the width interval between products is desired. This is because a wide width gap cannot be set.

As described above, when the conventional work hanger is used for general purposes regardless of the size of the substrate product, the actual situation is that the conventional work hanger is configured in accordance with the substrate product having a small width. Therefore, when plating a substrate product having a relatively large width size, a wide unstable range that is not supported by the clamps for holding the hanger remains on both ends in the width direction of the substrate product having a large width size. Although there is not so much trouble with a relatively thick substrate product, recently, there is an increasing trend in the demand for plating a considerably thin substrate product, and this substrate product with a relatively large width is reduced with a conventional work hanger. Even if you try to suspend and support in the liquid leaving the unstable range that is not supported by the clamping clamps at both ends in the horizontal width direction of the thin substrate product that is not supported by the clamping clips, The desired posture could not be maintained due to liquid resistance, etc., and it was bent, and as a result, normal plating treatment was not possible. Such an adverse effect is remarkable on the top side of the substrate product.
Utility Model Registration No. 3085849 JP 2003-328193 A Japanese Patent No. 2943070

  In this invention, the work hanger in the electroplating apparatus which can solve the bad effect which concerns is provided. In other words, it is a work hanger that is used for a wide range of substrate products from relatively small width products to large width products, and ensures that the upper and lower ends in the width direction of these substrate products differ in size. A work hanger for an electroplating apparatus that can be supported is provided. In particular, when plating a thin substrate product while transporting it in liquid, it is possible to prevent the both ends in the width direction of the thin base product from being bent by liquid resistance, etc., and normal plating processing while maintaining the desired posture The object is to provide a work hanger that can be used.

  In order to solve the above-described problems, the present invention provides a support portion that is suspended and supported so as to be movable in a horizontal direction along a horizontal cathode bar, and connected to the lower portion of the support portion. A horizontally long board portion extending in a parallel horizontal direction and a rectangular board product such as a printed circuit board to be plated, which is attached to the horizontally long board portion at a predetermined interval in the horizontal direction and is detachably sandwiched. And a plurality of clamping clamps for supporting the substrate product sandwiched by the sandwiching contact portion in a horizontally oriented vertical posture in a horizontal direction. A workpiece hanger configured to energize the substrate product from the sandwiching contact portion of the sandwiching clamp through the support portion, the horizontally long substrate portion, and the sandwiching clamp from the cathode bar. A clamping clamp attached to one end side or both end sides of the horizontally long substrate portion is slid in a horizontal direction along a slide guide portion provided on the horizontally long substrate portion and A slide base that is vertically attached to a projecting proximal end portion of the slide rod fixed to the horizontally long substrate portion and is slid in a horizontal direction separated from the end portion of the horizontally long substrate portion along the horizontally long substrate portion and Provided is a work hanger in an electroplating apparatus, which is configured as a slide movable clamp fixed to the horizontally long substrate portion at a slide movement position.

  Furthermore, the present invention provides a bifurcated structure in which the slide movable clamp is slid horizontally in the horizontal direction along the slide guide portions provided on the front and back surfaces of the horizontally long substrate portion and fixed to the horizontally long substrate portion at the slide movement position. It is characterized in that it is attached in a suspended state to the projecting proximal end portion of the outer slide rod.

  Further, according to the present invention, a tightening bolt that is screwed into a screw hole formed at an inward bifurcated tip portion of the slide rod is penetrated through a horizontal long hole formed in the horizontally long substrate portion, and the long The slide bolt is fixed to the horizontally long substrate portion by tightening the tightening bolt that has been slid to a desired position along the hole.

  According to the work hanger of the present invention, since it is possible to reliably support both upper end sides in the width direction of substrate products having different width sizes, particularly when a thin substrate product is plated while being transported in liquid, It is possible to prevent the both ends in the width direction from being bent due to liquid resistance or the like, and normal plating can be performed while maintaining the desired posture.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. First, the work hanger shown in FIGS. 1 to 5 will be described. The work hanger 1 includes a support portion 2 having a suspension portion 2a having a substantially bowl-shaped cross section that is suspended and supported in a horizontally movable manner while being slidably contacted along a horizontally disposed cathode bar B having a rectangular cross section. A horizontally long rectangular substrate 3 that is connected to a lower portion of the support 2 via a vertical support 2b and extends in a horizontal direction parallel to the cathode bar B, and the horizontally long substrate 3 is disposed at a predetermined interval in the horizontal direction, and a holding contact portion 10 that can detachably hold an upper portion of a rectangular substrate product W such as a printed circuit board to be plated is disposed below the horizontally long substrate portion 3. The substrate product W sandwiched by the sandwiching contact portion 10 is composed of a plurality of (four in the illustrated embodiment) clamping clamps 4 that suspend and support the product in a horizontally long vertical orientation. ing. The work hanger 1 can be energized from the cathode bar B to the substrate product W from the clamping contact portion 10 of the clamping clamp 4 through the support portion 2, the horizontally long substrate portion 3, and the clamping clamp 4. In addition, these constituent parts are formed of a conductive material such as stainless steel or brass. A rectangular substrate product W suspended and supported on the work hanger 1 in a vertical position is placed between anodes (not shown) disposed in a plating treatment liquid A in a horizontally long plating treatment tank (not shown). It is transported continuously at a relatively slow speed in a vertical orientation in the horizontal direction, and in this transport process, the clamping bar passes from the cathode bar B through the support part 2, the horizontally long substrate part 3, and the clamping clamp 4. The plating process is performed while energizing from the sandwiching contact portion 10 of 4. In addition, an ejection nozzle (not shown) for jetting the plating solution from a position close to both surfaces of the substrate product W to be transported in the solution is installed in the plating treatment solution A in the plating treatment tank (not shown). In this case, the substrate product W is plated while passing through a narrow passage between the ejection nozzles. Conveyor means (not shown) for conveying the work hanger 1 in a horizontal direction while being in sliding contact with the cathode bar B is known, for example, in Japanese Patent No. 2943070 owned by the present applicant, An engagement claw (not shown) provided on the work hanger 1 is engaged with a toothed endless belt (not shown) that circulates in the horizontal direction, and the work hanger is conveyed along the cathode bar B in the horizontal direction. Can be used.

  Of the plurality (four in the illustrated embodiment) of the clamping clamps 4, two sliding clamps 4 attached to both end sides of the horizontally long substrate portion 3 are provided on the horizontally elongated substrate portion 3. The slidably moved along the portion 21 in the horizontal direction and attached to the protruding base end portion 22A in the outward direction of the slide rod 22 having a rectangular cross section fixed to the horizontally long substrate portion 3 at the slide movement position, It is configured as a slide movable clamp 20 that is slid in the horizontal direction separated from the end of the horizontally long substrate portion 3 along the horizontally long substrate portion 3 and fixed to the horizontally long substrate portion 3 at the slide movement position. The slide movable clamp 20 has a contracted position (solid line position in FIG. 1) in contact with the end of the horizontally long substrate portion 3 and an extended position (slidably moved in the horizontal direction separated from the end of the horizontally long substrate portion 3). 1 is moved in a sliding manner. The slide guide portion 21 and the slide rod 22 are formed of the same conductive material as that of the horizontally long substrate portion 3. Of the four clamping clamps 4 shown in the figure, the two clamping clamps 4 attached to the inner side of the horizontally long substrate portion 3 are the same as the conventional clamping clamp described in the background art. The substrate unit 3 is fixedly attached. Hereinafter, the two inner clamping clamps 4 fixedly attached to the horizontally long board portion 3 are referred to as fixed clamps 30.

  In the illustrated embodiment, the slide movable clamp 20 is slid horizontally in the horizontal direction along the slide guide portions 21 provided on both the front and back surfaces of the horizontally long substrate portion 3, and the horizontally long substrate is at the slide movement position. Screws formed on the bifurcated end portions 22a, 22a of the slide rod 22 in an inward bifurcated state, attached to the outward projecting proximal end portion 22A of the bifurcated slide rod 22 fixed to the portion 3 The tightening bolt 24 screwed into the hole 23 is passed through a horizontal long hole 25 formed in the horizontally long board portion 3, and the tightening bolt 24 slid and moved to a desired position along the long hole 25. The bifurcated portions 22 a and 22 a of the slide rod 22 are fastened to be fixed to the horizontally long substrate portion 3.

  When the slide movable clamp 20 is slid, the tightening bolt 24 is loosened and the loosened bolt 24 is slid along the elongated hole 25 while the slide rod 22 is moved along the slide guide portion 21. The slide bolt is horizontally moved to a desired mounting position, and the tightening bolt 24 is tightened at the desired position where the slide is moved to fix the bifurcated portions 22 a and 22 a of the slide rod 22 to the horizontally long substrate portion 3.

  In the embodiment shown in FIG. 1, of the plurality of clamping clamps 4, two clamping clamps 4 attached to both end sides of the horizontally long substrate portion 3 are configured as the slide movable clamp 20. This can be applied to a substrate product having a larger width size, and is desirable from the viewpoint of maintaining the right and left weight balance of the entire work hanger. However, in the present invention, among the plurality of clamping clamps 4, only the clamping clamp 4 attached to one end side (for example, the rear end side) of the horizontally long substrate portion 3 is configured as the slide movable clamp 20 described above. It does not exclude that. In the embodiment shown in FIG. 1, of the plural (four) clamping clamps 4, the two clamping clamps 4 attached to the inside of the horizontally long substrate portion 3 are configured as so-called fixed clamps 30. However, the fixed clamp 30 may be omitted, and only the two slide movable clamps 20 may be attached to both end sides of the horizontally long substrate portion 3.

  The structure itself of the clamping clamp 4 (the slide movable clamp 20 and the fixed clamp 30) is a known one disclosed in Japanese Utility Model Registration No. 3085849 or Japanese Patent Application Laid-Open No. 2003-328193. In the slide movable clamp 20 provided on both the left and right sides in FIG. 1, the clamping clamp 4 is fixed in a surface contact state so that the upper portion is electrically connected to the protruding proximal end portion 22A of the slide rod 22. In the two fixed clamps 30 fixed inside (not shown) and provided on the inner side of FIG. 1, the upper part is fixed in a surface contact state so as to be conductively connected to the back side of the horizontally long substrate part 3. A fixed-side clamping rod 5 fixed by a bolt (not shown) and provided with a fixed-side contact 5a at the bottom, and a bracket 7 fixed to an intermediate portion of the fixed-side clamping rod 5 via a shaft pin 8 The movable side holding rod 6 is pivotally mounted, and a movable side contact 6a facing the fixed side contact 5a is provided below the movable side holding rod 6. Further, an elastic member 9 comprising a coil spring is interposed between the upper side of the fixed side holding rod 5 and the upper side of the movable side holding rod 6, and the shaft pin 8 is moved by the elastic force of the elastic member (coil spring) 9. As a fulcrum, the movable contact 6a is urged in a closing direction with respect to the fixed contact 5a, and the substrate product W is in contact with the movable contact 6a closed with respect to the fixed contact 5a. The fixed contact 5a and the movable contact 6a are configured as the holding contact portion 10 so that the upper portion can be held vertically. The holding contact portion 10 resists the elasticity of the elastic member 9 (coil spring) and presses the upper side of the movable side holding rod 6 toward the upper side of the fixed side holding rod 5 to thereby fix the fixed side The movable contact 6a is separated from the contact 5a and opened. When the substrate product W is attached to or detached from the clamping clamp 4, the upper side of the movable clamping rod 6 of each clamping clamp 4 is simultaneously pressed against the elastic force of the elastic member 9 (coil spring). However, this pressing is performed using a mechanical forcing force (not shown). Each lower side of the fixed side holding rod 5 and the movable side holding rod 6 put in the plating solution A together with the substrate product W is an insulating cap 11 except for the fixed side contact 5a and the movable side contact 6a that are exposed. Each is detachably covered. The insulating cap 11 is formed of a rubber material (preferably silicon rubber) which is a nonconductive material having elasticity.

  In FIG. 1, reference numeral 12 denotes a conductive wire. In the two fixed clamps 30 provided on the inner side of FIG. 1, the upper portions of the movable side holding rods 6 of the clamping clamp 4 through the conductive wires 12. In the slide movable clamp 20 provided on the left and right sides of FIG. 1 in a conductive manner, each movable side sandwiching of the sandwiching clamp 4 via the conductive wire 12 is performed. The upper side of the flange 6 and the slide flange 22 are electrically connected to each other. As described above, the upper side of each fixed side holding rod 5 of the clamping clamp 4 is fixed in surface contact with the protruding base end portion 22A of the slide rod 22 (the horizontally long substrate portion 3 in the fixed clamp 30). However, the upper side of each movable side holding rod 6 of the clamping clamp 4 and the slide rod 22 (the horizontally long substrate portion 3 in the fixed clamp 30) are electrically connected to each other through the conductive wire 12. As a result, the substrate product W is efficiently energized from the holding contact portion 10 of both holding rods (fixed side holding rod 5 and movable side holding rod 6) of the clamping clamp 4 as a whole. The conductive efficiency from the clamping clamp 4 to the substrate product W can be increased, and the conductive efficiency from the cathode bar B to the substrate product W can be increased.

  In FIG. 1 and FIG. 5, reference numeral 40 denotes a fixed portion having a concave fixing groove portion 41 that is directed downward from a middle portion in the horizontally long direction of the horizontally long substrate portion 3, that is, horizontally, via a support member 42, and has a recessed portion directed downward. This fixed groove-shaped guide 40 has an upper side portion of the substrate product W supported by being suspended by the clamping clamp 4 in the horizontal width direction, that is, a substantially middle position in the horizontal direction in the concave fixed groove portion 41. It is loose enough to slide and can be guided from above. The fixed groove-shaped guide 40 put in the plating solution A is formed of a non-conductive material such as plastic.

  Next, another embodiment of the present invention will be described based on the drawings of FIGS. Similarly to the work hanger 1 of the previous embodiment, the work hanger 50 of this embodiment also has a support portion 2 that is suspended and supported in a horizontal direction along the horizontal cathode bar B, and a lower portion of the support portion. A horizontally long substrate portion 3 that is connected to the cathode bar B and extends in a horizontal direction parallel to the cathode bar B, and a printed circuit board that is attached to the horizontally long substrate portion 3 at a predetermined interval in the horizontal direction and plated. A sandwiching contact portion 10 capable of detachably sandwiching the upper portion of the rectangular substrate product W such as is disposed below the horizontally long substrate portion 3 and the substrate product W sandwiched by the sandwiching contact portion is directed in the horizontal direction. A plurality of clamping clamps 4 that are suspended and supported in a horizontally long vertical posture. The clamping clamps 4 pass from the cathode bar B through the support portion 2, the horizontally long substrate portion 3, and the clamping clamp 4. The clamping contact portion of It is configured to energized the substrate product W from 0.

  In the work hanger 50 shown in FIGS. 6 and 7, the plurality of clamping clamps 4 attached to the horizontally long substrate portion 3 are all the fixed clamps 30 described in the previous embodiment. In this embodiment, a slide movable groove-shaped guide 60 is provided in place of the slide movable clamp 20 of the previous embodiment. Other configurations are substantially the same as those of the previous embodiment. Therefore, in this embodiment, the detailed description of the structure shown with the same code | symbol as previous embodiment is abbreviate | omitted.

  The slide movable groove-shaped guide 60, which is a feature of the work hanger 50, is slid in the horizontal direction along the horizontally long substrate portion 3 and is fixed to the horizontally long substrate portion 3 at the slide movement position. Recessedly attached to the rear end of the protrusion, and supported in such a manner as to be slidable in the horizontal direction spaced apart from the rear end of the horizontally long substrate portion 3 along the horizontally long substrate portion 3. A concave slide groove portion 61 with the portion facing is provided. Then, the upper side portion of the substrate product W protruding backward from the suspension support position of the clamping clamp 4 attached to the rearmost portion of the horizontally long substrate portion 3 by the slide movable groove-shaped guide 60 is used as the concave slide groove portion 61. It is so loose that it can slide inside and is guided from above.

  The slide support member 62 is slidably fitted to the horizontally long board portion 3 and is slidably fitted to the horizontally long board portion 3 by a fastening bolt 64 at a slide movement position. The slide rod 65 extends rearward and has a rear end projecting from the rear end of the laterally long board portion 3. A support member 66 is attached to the projecting rear end of the front slide rod 65 of the slide support member 62. The slide movable groove-shaped guide 60 is attached in a suspended state. The slide movable groove-shaped guide 60 put in the plating solution A is formed of a non-conductive material such as plastic.

  As described in the background art, the work hanger is intended to carry out the plating process while transporting the liquid in the liquid while supporting it in a suspended manner leaving a wide unstable range that is not supported by the clamping clamps at both ends in the width direction of the thin substrate product. In this case, both ends in the width direction of a thin substrate product are bent without being able to maintain the desired posture due to liquid resistance, etc., and there is a problem that normal plating treatment cannot be performed. This is conspicuous on the front side of the substrate product and relatively small on the rear end side of the substrate product. In view of such a situation, in the work hanger of this embodiment, the upper part on the top side of the substrate product is supported by the fixed clamp 30, and the upper part on the rear end side of the substrate product is expected by the slide movable groove-shaped guide 60. It was guided so that the posture could be maintained, so that it could cope with the change in the width size of the substrate product. As a result, the projected rear portion of the substrate product W that protrudes rearward from the rear end portion of the horizontally long substrate portion and is not supported by the clamping clamp 4 has an intended posture by the slide movable groove-shaped guide 60. Can be maintained.

  Also in the embodiment of FIG. 6, a fixed groove-like guide 40 similar to that of the embodiment of FIG. 1 is provided. The concave fixed groove 41 of the fixed groove guide 40 and the concave slide groove 61 of the slide movable groove guide 60 are formed at the same horizontal position.

It is a front view of the present invention. It is a partially longitudinally enlarged side view along the line AA in FIG. It is a partial longitudinal cross-sectional enlarged side view of the slide movable clamp along a BB arrow line of FIG. It is a partial cross-sectional schematic plan view which follows the CC arrow line of FIG. It is an enlarged side view of a fixed groove-shaped guide. It is a front view which shows the other Example of this invention. FIG. 7 is an enlarged vertical side view of the clamping clamp taken along the line D-D in FIG. 6.
