Description

The present invention relates to a partial plating technique for partially plating a surface to be treated while transporting a strip-shaped member.

Patent Documents 1 and 2 provide a partial plating apparatus for partially plating a surface to be processed of a band-shaped member while transporting a band-shaped member such as a hoop material forming an electronic component or a film carrier tape for mounting the electronic component. Are listed.

The continuous partial plating apparatus described in Patent Document 1 has a drum of an electrode structure having a cylindrical side plate attached between a disk-shaped upper lid and a lower lid, and between the drum side plates. A cylindrical masking material is rotatably arranged on the outer side of the drum in the radial direction through a gap.

In the conventional partial plating apparatus, one side of the strip-shaped member is brought into contact with the outer peripheral surface of the cylindrical rotating body, and the portion of the one side of the strip-shaped member that does not require plating is masked by the outer peripheral surface of the rotating body. There is a limit to increasing the pressing force of the strip-shaped member against the outer peripheral surface of the rotating body, and the plating solution leaks from between the strip-shaped member and the masking surface of the rotating body, and the plating adheres to the surface opposite to the strip-shaped member. Sometimes. Therefore, unnecessary plating must be removed in a post-process, and high-quality plating cannot be efficiently performed.

It is difficult to obtain processing accuracy in order to process the masking pattern, which is the boundary between the plating-required portion and the plating-unnecessary portion, into the cylindrical surface of the masking material as in the conventional case. For this reason, the plating solution may leak to the masked portion, and the manufacturing yield of the partially plated parts could not be increased.

Further, if the strip-shaped member is brought into contact with the outer peripheral surface of the drum or the cylindrical member to mask the portion that does not require plating, only one side of the strip-shaped member that is in contact with the outer peripheral surface can be plated. For this reason, when plating on both sides continuously, at least two partial plating devices are required, and after plating one side of the strip-shaped member with the first plating device, the second device is used. It is necessary to plate the opposite side, that is, the other side with a plating device. Therefore, it was not possible to efficiently plate both sides of the strip-shaped member.

An object of the present invention is to enable high-precision partial plating to be efficiently performed on a surface to be plated of a strip-shaped member.

The partial plating apparatus of the present invention has a transport mechanism for transporting a strip-shaped member by forming a straight portion extending straight to the strip-shaped member, and moving forward in synchronization with the strip-shaped member in the transport direction of the straight portion of the strip-shaped member. A moving table that moves backward from the forward limit position to the initial position, and a first masking jig that is mounted on the moving table so as to move away from and away from the band-shaped member and presses against one surface of the band-shaped member. A liquid chamber that has a second masking jig that is mounted on a moving table so that it can move closer to and away from the strip-shaped member and presses against the other surface of the strip-shaped member, and communicates with an opening that opens to the surface to be processed. Is provided in the first masking jig, and a masking plate having a shape corresponding to the area requiring plating applied to the surface to be treated is provided in the opening of the first masking jig. The first masking jig and the second masking jig are pressed against the band-shaped member to sandwich the band-shaped member, and the moving table is moved forward while transporting the band-shaped member to obtain a plating-required area of the surface to be processed. Plating process.

The partial plating method of the present invention is a partial plating method in which only a necessary region of a surface to be treated of a strip-shaped member is plated by using the partial plating apparatus, and the first masking jig and the second masking are performed. In the sandwiching process in which the jig is pressed against the band-shaped member to sandwich the band-shaped member, and in the state where the band-shaped member is sandwiched by the two masking jigs, the band-shaped member is conveyed and the moving table is moved forward. However, in the processing step of plating the required area for plating on the surface to be processed, and when the moving table reaches the advancing limit position, the transportation of the strip-shaped member is stopped, and the first masking jig and the second masking treatment are performed. It has a separation step of separating the tool from the band-shaped member, and a retreat step of retreating the moving table from the advancing limit position to the initial position to retreat the masking jig.

Two masking jigs are arranged on the moving table that moves forward and backward in synchronization with the straight portion of the strip-shaped member so that they can move closer to each other toward the strip-shaped member. , A masking plate is provided in which communication holes having a shape corresponding to the area requiring plating applied to the surface to be treated are formed. Since both sides of the strip-shaped member are pressed and sandwiched, the plating solution is prevented from leaking from between the strip-shaped member and the masking plate, a high-quality plating product can be manufactured, and unnecessary plating is performed later. The plating process can be performed efficiently without removing it in the process.

Since the masking material is pressed against the straight portion of the strip-shaped member, it can be made into a flat shape without being curved into a cylindrical shape. As a result, the masking pattern, which is the boundary between the parts requiring plating and the parts not requiring plating, can be processed into a flat masking plate, so that the processing accuracy of the masking pattern can be improved and the yield of high-quality partially plated parts can be improved. Can be manufactured.

Since the two masking jigs arranged on both sides of the strip-shaped member in the transport direction can simultaneously perform partial plating on both sides of the strip-shaped member, the partial plating process can be efficiently performed.

As described above, in the strip-shaped member 12, both surfaces to be processed are pressed by both masking jigs 41 and 42 and sandwiched, that is, supported in a sandwiched state. Therefore, even if the strip-shaped member 12 is strongly pressed, the strip-shaped member 12 is deformed. There is nothing to do.

An air cylinder 61a with a slide table is attached to the moving table 24 adjacent to the side plate 33b, and two drive rods 64a are attached to the drive block 63a attached to the slide table 62a of the air cylinder 61a. The drive rod 64a penetrates the side plate 33b and is connected to the masking jig 41. The air cylinder 61a drives the masking jig 41 in a direction of approaching and moving toward the band-shaped member 12 and in a direction away from the band-shaped member 12, and exerts a pressing force on the band-shaped member 12 of the masking plate 51a.

The second masking jig 42 has the same structure as the first masking jig 41, and the member constituting the masking jig 42 has a reference numeral b instead of the reference numeral a in the member constituting the masking jig 41. Is attached, and detailed description is omitted.

A liquid chamber 48b into which the plating solution is injected is provided inside the masking jig 42, and the surface to be processed is provided on the inner side surface of the masking jig 42, that is, the side surface of the strip-shaped member 12 facing the surface to be processed T2.

FIG. 5 is a diagram showing an example of a partial plating pattern applied to the strip-shaped member 12, and shows a part of a long strip-shaped member.

Feed holes 65 are provided on both sides of the strip-shaped member 12 at regular intervals. By detecting the position of the feed hole 65 with the position detection sensor 40, it is possible to detect the reference position of the masking plates 51a and 51b with respect to the strip-shaped member 12 in the transport direction. However, instead of using the position of the feed hole 65 as the reference position, another portion may be used as the reference position.

In FIG. 5, the hatched circular portion 66 and the rectangular portion 67 are partially plated, and the other portions are not plated. In this case, the region corresponding to the circular portion 66 and the rectangular portion 67 is set as a plating required region, and a communication hole having a shape corresponding to the plating required region is formed in the flat masking plate.

FIG. 5 shows a portion of partial plating applied to the surface to be treated on one side, and when both sides are to be treated, communication holes having a shape corresponding to the required area for plating are formed on both masking plates. Will be done.

The flat masking plates 51a and 51b on which the plating required region is formed are formed of highly elastic members and are pressed by the straight strip-shaped member 12 which extends straight, so that the masking member has a cylinder as in the conventional case. The masking pattern can be formed with higher processing accuracy than when the masking pattern is formed on the surface. As a result, the plating process can be performed with a high-precision pattern, leakage of the plating solution from the masking plate can be prevented, and the manufacturing yield of the partially plated product can be solidified.

The above-mentioned partial plating apparatus 10 includes a first masking jig 41 and a second masking jig 42, and the hoop material, that is, both sides of the strip-shaped member 12 are used as surfaces to be processed, and these are simultaneously plated. Can be done. However, by supplying the plating solution to only one of the two masking jigs 41 and 42, the plating process can be performed using only one surface, that is, one surface of the strip-shaped member 12 as the surface to be processed. In that case, as the masking plate of the other masking jig, a flat plate having elasticity is used in which the communication holes having a shape corresponding to the plating-required region are not formed and the entire region is the plating-unnecessary region. To. Since the elastic plate is pressed against the surface to be plated, it is possible to prevent the plating solution from leaking from the surface to be plated. As a result, it is possible to prevent the plating from adhering to the surface of the strip-shaped member 12 that is not plated, and it is not necessary to remove unnecessary plating in the subsequent process, so that the high-quality plating treatment can be carried out with good yield and efficiency. It becomes possible to do it.

Next, with reference to FIGS. 6 and 7, a plating method for partially plating both surfaces of the strip-shaped member 12 as surfaces to be processed T1 and T2 by the partial plating apparatus 10 will be described.

The partial plating apparatus 10 can be used to perform gold plating on the hatched portions of the strip-shaped member 12 to be processed, T1 and T2 in FIG. 5. The surface to be treated of the strip-shaped member 12 is pre-plated with nickel or the like.

In order to perform the plating process, as shown in FIGS. 1 and 2, the masking jigs 41 and 42 are separated from the strip-shaped member 12, and the drive roller 15 is driven by the drive source to perform the strip-shaped member. 12 transport is started. When it is detected by the signal from the position detection sensor 40 that the strip-shaped member 12 has been conveyed to the reference position, the moving table 24 is driven by the drive mechanism 26 to move the plating processing tank 30 to the initial position shown in FIG. 1, that is, to retract. From the limited position, move forward as shown in FIG. 6 (A). The forward moving speed at that time is the same as the transport speed of the strip-shaped member 12, and the plating treatment tank 30 is driven forward in synchronization with the transport of the strip-shaped member 12.

Under the state where the plating treatment tank 30 and the strip-shaped member 12 are synchronized, as shown in FIG. 6B, the first masking jig 41 is moved closer to the strip-shaped member 12 by the air cylinder 61a. At the same time, the second masking jig 42 is moved closer to the band-shaped member 12 by the air cylinder 61b. As a result, the masking plate 51a of the masking jig 41 is pressed against the surface T1 to be processed of the band-shaped member 12, the masking plate 51b of the masking jig 42 is pressed against the surface T2 to be processed of the band-shaped member 12, and the band-shaped member 12 is masked. It is sandwiched by jigs 41 and 42. FIG. 6B shows a state in which the pinching process is completed.

In this way, under the state where the band-shaped member 12 is sandwiched between the two masking jigs 41 and 42, the plating process is performed while the band-shaped member 12 is conveyed and the moving table 24 is moved forward. In this processing step, the plating solutions filled in the liquid chambers 48a and 48b are sprayed onto the surfaces T1 and T2 to be processed, and the power supply unit is turned on. FIG. 7A shows a state in which the plating treatment tank 30 reaches the forward limit position by the moving table 24 and the forward movement of the plating treatment tank 30 is stopped while performing the plating treatment.

When the moving table 24 reaches the forward limit position and the plating process is completed, the transport of the strip-shaped member 12 is stopped, and the two masking jigs 41 and 42 are attached to the strip-shaped member 12 as shown in FIG. 7 (B). Separate from. When the separation step is completed, the moving table 24 moves the plating treatment tank 30 backward from the forward limit position shown in FIG. 7 (B) to the initial position shown in FIG. When this retreat step is completed, the plating treatment step described above is repeated.

As in the past, when performing partial plating on both sides, at least two partial plating devices were required, but this partial plating device 10 is provided with two masking jigs 41 and 42. Since both sides of the strip-shaped member 12 can be partially plated at the same time, the plating can be efficiently performed even when the partial plating is performed on both sides. The partial plating apparatus 10 is suitable for partial plating of expensive metals such as palladium, rhodium, and ruthenium in addition to gold as the type of metal to be plated on the strip-shaped member 12. After the plating treatment, the strip-shaped member including the partially plated portion is cut out, and a final product is manufactured by processing such as bending.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist thereof. For example, as the strip-shaped member 12, as shown in FIG. 5, a member that is flat as a whole is shown, but a member that has been partially punched before the plating process is also plated. It can be performed.
