Description

The present invention relates to a plating jig for buttons and a method for plating buttons. More specifically, it relates to a jig used when electroplating metal buttons, such as button bodies, snap buttons, and their components, and a method for electroplating buttons using this jig.

When electroplating a large number of metal buttons, etc., a plating jig is used, which has multiple horizontal bars with numerous hooks on the top and bottom. After the buttons to be plated are hooked onto each hook of the jig, the jig is immersed in the plating solution, and a voltage is applied from an external power source between each button and an electrode (anode) in the plating solution, causing a current to flow through the plating solution, thereby plating each button. With the above jig, it is necessary to hook each button onto the hook one by one, and then remove each button from the hook one by one after plating, which is time-consuming.

US Patent Application Publication No. 2014/0331924

One of the objects of the present invention is to provide a plating jig for buttons that reduces the effort required to attach and remove buttons.

U.S. Patent Application Publication No. 2014/0331924 discloses a holder capable of holding multiple workpieces to be electroplated in guide tracks formed by rods. In this holder, the workpieces are closely arranged in each guide track so that they are in contact with each other. As a result, the contact points between two adjacent workpieces and the contact points between each workpiece and the rod become fixed, which can result in plating defects at these contact points.

Another object of the present invention is to provide a plating jig for buttons and a method for plating buttons that are less likely to produce plating defects on buttons.

To solve the above problems, one aspect of the present invention provides a plating jig for buttons used when electroplating metal buttons, comprising: non-conductive top and bottom plates, each having a number of holes for passing a plating solution; and one or more button storage compartments defined in the space between the top and bottom plates, each capable of storing a row of buttons so that the peripheral edges of two adjacent buttons face each other. Each button storage compartment includes an electrically conductive bottom section that contacts the buttons stored therein to allow electricity to flow through it, and a button inlet port provided on at least one of both ends of each button storage compartment in the direction in which the buttons are lined up in a row. The jig further comprises an opening/closing member that can open and close the button inlet port, and an electrically conductive vertical frame that connects the electrically conductive bottom section of each button storage compartment to a power source.

In this invention, metal buttons, particularly button bodies, snap buttons, and their components, are suitable targets for plating.

In the button plating jig of the present invention, one or more button storage compartments are defined between the front and back plates. Each button storage compartment stores multiple buttons in a row, with the peripheral edges of adjacent buttons facing each other, i.e., with the peripheral edges of two adjacent buttons touching or adjacent to each other. Multiple buttons are introduced into each button storage compartment through a button inlet, which is then closed by an opening/closing member. The jig is then immersed in plating solution, and a voltage is applied between the jig and an anode in the plating solution using an external DC power source. The conductive bottom of each button storage compartment is connected to the negative pole of the external DC power source via a vertical conductive frame or similar. The buttons in each button storage compartment are supported by the conductive bottom and are in direct contact with the conductive bottom and with the plating solution flowing in through the numerous holes in the non-conductive front and back plates. This allows current to flow between the anode and each button via the plating solution or similar, plating each button.

In the button plating jig of the present invention, multiple buttons are fed into each button storage section through the button inlet, and the button inlet is closed with the opening/closing member to complete the setting of the buttons in the jig. After plating, the buttons can be removed from the jig by ejecting them from each button storage section through the button inlet. This reduces the effort required to install and remove buttons. Buttons can be inserted into and removed from each button storage section by tilting the jig as required so that the buttons roll or slide from their peripheral edges along the conductive bottom.

In the present invention, each button storage section can have a gap that allows each button to swing in the alignment direction when it contains the largest number of buttons and the opening/closing member closes the button introduction port. In this case, when each button storage section is packed with buttons at its densest and the button introduction port is closed by the opening/closing member, each button storage section is designed to leave a gap, or space, that allows each button to swing in one direction or the other in the alignment direction. This gap allows the buttons in each button storage section to swing in the alignment direction during plating, changing the contact point between each button and the conductive bottom in the alignment direction. This prevents the contact point from becoming fixed, making plating defects less likely to occur.

In one embodiment of the present invention, the jig includes a jig body including the front plate, the back plate, and the one or more button storage sections, and the vertical conductive frame includes an angled upper portion extending upward at an angle relative to the jig body. In this case, when placing the button plating jig in a plating tank, the angled upper portion of the vertical conductive frame is vertical. This allows the jig body to be tilted relative to the vertical, and the buttons can be positioned to minimize contact with the front plate during plating. Note that if the buttons come into contact with the front plate during plating, the surfaces of the buttons may be scraped or scratched. The angle of the angled upper portion relative to the jig body can be set, for example, to be greater than or equal to 15° and less than or equal to 45°.

According to another aspect of the present invention, a frame jig is provided that can use multiple plating jigs for buttons according to the present invention as described above, each tilted and arranged in parallel. By using such a frame jig, multiple plating jigs for buttons can be arranged in parallel in a plating tank, tilted from the vertical. This makes it possible to plate a large number of buttons at once while minimizing contact of the buttons with the top plate during plating.

In yet another aspect of the present invention, there is provided a method for electroplating metal buttons using a jig, comprising: a first step of arranging a plurality of buttons in a row in one or more button storage sections of the jig so that the peripheral edges of two adjacent buttons face each other; and a second step of immersing the jig in a plating solution and passing a current through the plating solution from an external power source, wherein in the second step, the plurality of buttons in each button storage section are swung in a direction in which the plurality of buttons are lined up in a row.

In the button plating method according to the present invention, the jig is immersed in the plating solution, and in the second step, an electric current is passed through the plating solution from an external power source. In this step, the buttons in each button storage compartment are swung in the direction of their arrangement. This prevents the electrical contacts of the buttons from becoming fixed, making plating defects less likely to occur.

In the button plating jig of the present invention, multiple buttons are fed into each button storage section through the button inlet, and the button inlet is closed with the opening/closing member, completing the setting of the buttons in the jig. After plating, the buttons can be removed from the jig by ejecting them from each button storage section through the button inlet. This reduces the effort required to attach and remove buttons.

In addition, in the button plating jig and button plating method according to the present invention, by allowing the buttons in each button storage section to swing in the line-up direction during plating, the electrical contacts of each button do not become fixed, making plating defects less likely to occur.

The following describes an embodiment of the present invention based on the drawings, but the present invention is not limited to such an embodiment and can be modified within the scope of the claims.

[First embodiment]
FIG. 1 is a plan view of a plating jig for buttons (hereinafter also simply referred to as "jig") 100 according to a first embodiment of the present invention, showing the empty state before buttons 10 (see FIGS. 2, 4, etc.) are accommodated. FIG. 2 is a plan view with a portion of the jig 100 cut away, showing the state in the middle of accommodating buttons 10. FIG. 3 is also a plan view with a portion of the jig 100 cut away, showing the state after buttons 10 have been accommodated. FIG. 4 is a cross-sectional view taken along line A-A in FIG. 3. In the following description, the up-down and left-right directions of the jig 100 are based on the plane of FIG. 1. Furthermore, the front and back sides of the jig 100 (and buttons 10) correspond to the left and right sides, respectively, on the plane of FIG. 4.

Figure 5 is a side view of button 10. Button 10 is an example of a metal button that can be electroplated using jig 100. Button 10 is, for example, the cap portion of a snap button, which includes a leg portion with a protrusion extending from the center of one main surface of a flat plate, and a cap portion covering the other main surface of the leg and the peripheral edge of one main surface of the leg. Button 10 includes a disk-shaped top plate 11 and a peripheral side plate 12 extending from the radially outer end of top plate 11 to the back side. In this embodiment, the surface 11a of top plate 11 is flat or curved, slightly convex toward the front side (upward in the plane of Figure 5). Hereinafter, based on Figure 5, the surface 11a of top plate 11 will be described as being curved, slightly convex toward the top side, but surface 11a may also be flat. In this embodiment, the center 11b of surface 11a protrudes furthest toward the front side. The inner and outer diameters of the peripheral plate 12 are approximately constant in the axial direction (front-to-back direction) of the button 10. In this embodiment, the main targets of electroplating on the button 10 are the front surface 11a of the top plate 11 and the outer surface 12a of the peripheral plate 12, but this is not limited to these; the back surface of the top plate 11 of the button 10 and the inner surface of the peripheral plate 12 may also be targets. In this embodiment, the thickness T of the button 10 is defined as the distance along the axial direction between the center 11b of the front surface 11a of the top plate 11 and the back edge of the peripheral plate 12. Reference number D in Figure 5 represents the diameter of the button 10. The diameter of the button 10 is, for example, Φ16 mm.

1 to 4, the button plating jig 100 comprises a substantially rectangular box-shaped jig body 101 and two conductive vertical frames 102a, 102b connected to the left and right sides of the jig body 101, respectively, and extending upward from the jig body 101. The jig body 101 comprises a front plate 120 and a back plate 130 each having a rectangular shape elongated in the left-right direction, five horizontal frames 140 that vertically divide the space between the front and back plates 120, 130 into, for example, four sections, a left-closing vertical frame 150 that closes the left end of the space between the front and back plates 120, 130, and a stopper 160 as an opening/closing member that can open and close the right end of the space between the front and back plates 120, 130. The jig body 101 includes four button storage sections 110 vertically divided by the five horizontal frames 140 between the front and back plates 120, 130. The left end of each button storage section 110 is closed by a left closing vertical frame 150. The right end of each button storage section 110 is open as a button introduction port 111 for introducing buttons 10 into each button storage section 110, and each button introduction port 111 is opened and closed by a stopper 160.

The lower portion of the conductive vertical frame 102a is connected to the jig body 101 so as to abut the left side of the left closed vertical frame 150. The left end of each button storage section 110 may be closed by the lower portion of the conductive vertical frame 102a rather than the left closed vertical frame 150. The area of the jig body 101 near the button introduction port 111 of each button storage section 110 is reinforced by the right vertical frame 170. The lower portion of the conductive vertical frame 102b is connected to the jig body 101 so as to abut the right side of the right vertical frame 170. The right vertical frame 170 and the conductive vertical frame 102b leave the button introduction port 111 of each button storage section 110 open. The conductive vertical frames 102a and 102b are connected to the negative pole of an external DC power supply (not shown) via an electric wire or the like during plating. The conductive vertical frames 102a and 102b are also driven by an actuator (not shown) to continuously swing left and right during plating.

1 and 3 show the stopper 160 closing the button introduction port 111 of each button storage section 110 (closed state), while FIG. 2 shows the stopper 160 opening each button introduction port 111. The stopper 160 comprises a base 161 that is long in the vertical direction, and four stopper portions 162 that protrude to the left from the base 161 in the vertical direction. The back plate 130 of the jig body 101 includes an extension portion 130a (see FIG. 2) that extends further to the right than the front plate 120. Screw-type fasteners 163 for fixing the stopper 160 in the closed state are disposed near the upper and lower ends of the front side of the extension portion 130a. Notches 164 for receiving the fasteners 163 are provided near the upper and lower ends of the base 161 of the stopper 160. The stopper 160 is placed in a closed state by positioning each fastener 163 so that it is received in each notch 164 and then tightening the fastener 163 screws. Each button introduction port 111 can be opened by loosening the fastener 163 screws and removing the stopper 160. Referring to Figure 3, when the stopper 160 is in the closed state, each plug portion 162 of the stopper 160 extends slightly from each button introduction port 111 toward each button storage section 110. Furthermore, in the closed state, the right edge of the base 161 of the stopper 160 coincides with the right edge of the extension portion 130a of the back plate 130.

The front plate 120 and back plate 130 are each made of a non-conductive material and have numerous holes 121, 131 (see Figure 4, etc.) for passing plating solution through the button storage section 110. In this embodiment, the front plate 120 is a mesh sheet made of, for example, polyvinyl chloride or polypropylene, and the back plate 130 is a polyvinyl chloride plate with numerous punched holes (131). As can be seen from Figure 4, the thickness of the back plate 130 is greater than the thickness of the front plate 120, but may be the same. The holes 121, 131 in the front plate 120 and back plate 130 are large enough to prevent buttons 10 from passing through. The distance between the front plate 120 and back plate 130, i.e., the length of the button storage section 110 in the front-to-back direction, is set to be slightly larger than the thickness T of the buttons 10 and less than twice the thickness T of the buttons 10.

Referring to Figure 3, the five horizontal frames 140 consist of, from top to bottom, a first horizontal frame 141, a second horizontal frame 142, a third horizontal frame 143, a fourth horizontal frame 144, and a fifth horizontal frame 145. Hereinafter, the four button storage sections 110 will also be referred to, from top to bottom, as the first storage section 110A, the second storage section 110B, the third storage section 110C, and the fourth storage section 110D. The first horizontal frame 141 closes the space between the upper ends of the front and back plates 120 and 130 and defines the top surface of the first storage section 110A. The second horizontal frame 142 defines the bottom surface of the first storage section 110A and the top surface of the second storage section 110B. The third horizontal frame 143 is located in the vertical middle of the front and back plates 120 and 130 and defines the bottom surface of the second storage section 110B and the top surface of the third storage section 110C. The fourth horizontal frame 144 defines the bottom surface of the third storage section 110C and the top surface of the fourth storage section 110D. The fifth horizontal frame 145 closes the space between the lower ends of the front and back plates 120 and 130 and defines the bottom surface of the fourth storage section 110D. In this embodiment, the thickness of the first, third, and fifth horizontal frames 141, 143, and 145 in the front-to-back direction is slightly greater than the distance between the front and back plates 120 and 130, and the front and back surfaces of the first, third, and fifth horizontal frames 141, 143, and 145 are exposed to the outside of the jig body 101. The thickness of the second and fourth horizontal frames 142 and 144 in the front-to-back direction is approximately the same as the distance between the front and back plates 120 and 130, and the second and fourth horizontal frames 142 and 144 fit between the front and back plates 120 and 130. The front and back surfaces of the left closed vertical frame 150 and right vertical frame 170 are flush with the front and back surfaces of the first, third, and fifth horizontal frames 141, 143, and 145.

The buttons 10 are introduced into each button storage section 110 through the corresponding button inlet 111. Each button storage section 110 is substantially the same size, and the spacing between each button storage section 110 in the front-to-back direction is set to be slightly greater than the thickness T of the buttons 10, but less than twice the thickness T, as described above. This prevents two buttons 10 from overlapping in the front-to-back direction of the button storage section 110. The vertical length of each button storage section 110 is also set to be slightly greater than the diameter D of the buttons 10. The vertical length of each button storage section 110 is less than twice the diameter D of the buttons 10. This prevents two buttons 10 from overlapping in the top-to-bottom direction of each button storage section 110. The multiple buttons 10 introduced into each button storage section 110 are lined up in a row so that the peripheral side plates 12 of two horizontally adjacent buttons 10 face each other. In this specification, the direction in which multiple buttons 10 are lined up in a row within each button storage section 110 is referred to as the "line-up direction."

The left-right length of each button storage compartment 110 is defined as the distance between the right side of the left closing vertical frame 150 that closes the left end of each button storage compartment 110 and the left end face of each stopper portion 162 of the stopper 160 in the closed state. The left-right length of this button storage compartment 110 is set so that when each button storage compartment 110 contains the maximum number of buttons 10, a distance M (see Figure 3) is created that allows the buttons 10 to swing in the alignment direction. This distance M is less than the diameter D of the buttons 10, and is preferably approximately half the diameter D.

The second to fifth horizontal frames 142, 143, 144, and 145 that define the bottom surfaces of the first to fourth storage sections 110A, 110B, 110C, and 110D, respectively, are conductive bottom sections that come into contact with the multiple buttons 10 stored in each button storage section 110, allowing electricity to flow through them. More specifically, the second to fifth horizontal frames 142, 143, 144, and 145 are made of a conductive material and support each of the multiple buttons 10 stored in each button storage section 110 so that they come into direct contact with the buttons 10. During plating, electricity flows between the buttons 10 and the second to fifth horizontal frames 142, 143, 144, and 145. The first horizontal frame 141 may also be made of a conductive material, but a non-conductive material is preferable in terms of the durability of the jig 100.

The second to fifth horizontal frames 142, 143, 144, and 145 are electrically connected to the current-carrying vertical frames 102a and 102b. In this embodiment, as shown in Figure 4, the current-carrying vertical frames 102a and 102b are tightened to the left and right ends of the second to fifth horizontal frames 142, 143, 144, and 145 with non-conductive screws 103, thereby bringing the current-carrying vertical frames 102a and 102b into contact with the second to fifth horizontal frames 142, 143, 144, and 145, thereby conducting electricity.

Next, we will explain the process (first process) of storing multiple buttons 10 in each button storage section 110 of the jig 100. First, multiple buttons 10 are fed into each button storage section 110 of the jig body 101 through the button inlet 111. During this process, as shown in Figures 2 and 3, the jig body 101 is tilted so that the left side is downward. This allows each button 10 to roll or slide from the button inlet 111 to the left end of each button storage section 110 on the second to fifth horizontal frames 142, 143, 144, and 145, facilitating the button storage process. As an example, the maximum number of buttons 10 can be placed in the lowest fourth storage section 110D, followed by the same number of buttons 10 in the third storage section 110C, the second storage section 110B, and the first storage section 110A. While each button storage section 110 stores the maximum number of buttons 10, this is not a limitation. The centers of the multiple buttons 10 in each button storage section 110 are aligned on a straight line in the arrangement direction. After the buttons 10 have been stored in each button storage section 110, the stopper 160 is closed. This completes the setting of the buttons 10 into the jig 100.

Next, the plating process (step 2) will be described. First, the jig body 101 of the jig 100 is immersed in a plating solution (not shown) in a plating tank (see reference number 1 in Figure 6). An anode (see reference number 2 in Figure 6) is placed in the plating solution and connected to the positive terminal of a DC power supply external to the plating solution. The vertical conductive frames 102a and 102b of the jig 100 are connected to the negative terminal of the DC power supply. As an example, a plate-shaped anode is placed vertically in the plating solution, and the distance between this anode and the jig 100 is preferably approximately 300 mm. Furthermore, although not shown, the upper ends of the vertical conductive frames 102a and 102b exposed to the outside of the plating solution are connected to the output terminal of an actuator that swings the jig body 101 left and right. In this state, a voltage is applied between the anode in the plating solution and the jig body 101 from an external power source, causing a current to flow through the plating solution. As a result, electricity flows through the second to fifth horizontal frames 142, 143, 144, and 145, which form the conductive bottom of each button storage section 110, to each button 10 housed in the jig body 101, and plating is applied to each button 10.

During the plating process, the jig body 101 is continuously oscillated back and forth by the actuator. Oscillation conditions include, for example, an oscillating speed of 50 reciprocations per minute and a lateral stroke of 94 mm. This causes each button 10 in each button storage section 110 to oscillate back and forth in the alignment direction during plating. That is, each button 10 rolls or slides on the second through fifth horizontal frames 142, 143, 144, and 145 in one direction, then rolls or slides to the other direction, repeating this movement back and forth. This changes the contact point between each button 10 and the conductive bottom (second through fifth horizontal frames 142, 143, 144, and 145) in the alignment direction, preventing plating defects such as plating burns. It also reduces uneven plating thickness.

Once the plating process and subsequent processing are completed, the stopper 160 is removed from the jig body 101, the jig body 101 is tilted so that the right side is facing downward, and the buttons 10 in each button storage section 110 can be easily ejected through the open button inlet 111.

Second Embodiment
FIG. 6 is a side view schematically illustrating a jig 100a according to a second embodiment of the present invention placed in a plating tank 1. The jig 100a of the second embodiment differs from the jig 100 of the first embodiment in that the portions of the conductive vertical frames 102a, 102b extending upward from the jig body 101 are angled and connected to the jig body 101 as angled upper portions 102c. The configuration of the jig 100a other than the angled upper portions 102c is substantially the same as that of the jig 100, and therefore in FIG. 6, the jig body is designated by the reference numeral 101 and the front plate is designated by the reference numeral 120. Referring to FIG. 6, when placing the jig 100a in the plating tank 1, the angled upper portions 102c are vertical. This allows the jig body 101 to be tilted at an angle θ relative to the vertical. The angle θ can be, for example, 15° to 45°, more preferably 20°. During plating, particularly when the jig 100a is oscillated, the surfaces 11a of the buttons 10 may come into contact with and rub against the front plate 120 of the jig body 101, scratching the surface 11a and resulting in poor appearance. By tilting the jig body 101 at an angle θ, it is possible to reduce contact between the surfaces 11a of the buttons 10 and the front plate 120 of the jig body 101 during oscillation, thereby suppressing poor appearance.

In addition, in Figure 6, as an example, a plate-shaped anode 2 is placed vertically in the plating tank 1. If the distance between this anode 2 and the jig body 101 is too short, plating burns may occur. Therefore, as an example, plating burns can be effectively prevented by setting the distance D1 between the anode 2 and the upper end of the jig body 101 to 300 mm or more, and the distance D2 between the anode 2 and the lower end of the jig body 101 to 260 mm or more.

[Third embodiment]
FIG. 7 is a side view showing four button plating jigs 100A arranged in a tilted parallel arrangement on a frame jig 200 according to the present invention, as an example. FIG. 8 is a front view of FIG. 7, but only one jig 100A is shown. FIGS. 7 and 8 show a third embodiment of the present invention. FIG. 9 is a partially cutaway plan view of the jig 100A shown in FIGS. 7 and 8. Referring to FIG. 9, the jig 100A according to the present invention differs from the jig 100 of the first embodiment mainly in the following respects: the left and right conductive vertical frames 102aA and 102bA of the jig 100A do not extend above the jig body 101A. Furthermore, the jig body 101A is longer in the left-right direction than the jig body 101, thereby increasing the number of buttons 10 that can be accommodated in each button accommodating section 110E. Other than these points, the configuration of jig 100A is substantially the same as jig 100, and jig 100A includes a front plate 120A, a back plate 130A, second to fifth horizontal frames 142A, 143A, 144A, 145A, a stopper 160A, etc. The second to fifth horizontal frames 142A, 143A, 144A, 145A serve as conductive bottom portions of the corresponding button storage compartments 110E.

7 and 8, multiple jigs 100A are connected to the frame jig 200 in parallel at an angle. Specifically, the jigs 100A are connected to the frame jig 200 at an angle of 15° to 45°, more preferably 20°, similar to the angle θ (see FIG. 6) described above in connection with the second embodiment. By setting such an angle, contact between the surface 11a of the buttons 10 and the front panel 120A of the jig 100A is reduced, thereby preventing poor appearance. The frame jig 200 is configured in a roughly rectangular box shape, consisting of left and right vertical frames 201 and multiple horizontal frames 202 arranged above and below. An extension member 203 extending further upward is added to the top horizontal frame 202. The vertical frame 201, horizontal frame 202, and extension member 203 are electrically conductive, and jig 100A is attached to frame jig 200 using conductive screws or the like so that they are electrically connected to the electrically conductive vertical frames 102aA and 102bA of jig 100A.
