The plating apparatus according to the embodiment of the present invention includes a plating cell 10 , a plating unit 20 , a washing unit and a transfer unit 40 .

The plating cell 10 is made such that the object to be plated is put into the space formed therein and can be moved. These plating cells are mounted on the plating unit 20 . The plating unit 20 performs a plating operation while the plating cell 10 is mounted and the plating cell 10 is filled with a plating solution and rotated.

On the other hand, the washing unit 20 is composed of a unit separate from the plating unit 10, the plating cell 20 is mounted, and the plating solution is filled with a washing solution and rotated to perform a washing operation.

The transfer unit 40 holds the plating cell 10 and moves it to the plating unit 10 and the washing unit 20 to perform a continuous operation.

The rotary plating device configured in this way can move the plating cell, and the plating cell can be mounted on a device that performs individual tasks such as plating or washing, so that the overall process can be automated, and the device for performing individual tasks can be used appropriately. There is an effect that the plating process can be performed quickly by arranging it at an appropriate position in number.

Hereinafter, the configuration of each part will be described in detail with reference to the drawings.

1 is a perspective view of a rotary plating apparatus according to an embodiment of the present invention, FIG. 4 is a perspective view of a plating cell employed in the rotary plating apparatus, and FIG. 6 is a cross-sectional view of the plating cell.

The plating cell 10 includes a body part 11 , a bottom part 12 and a cover part 13 as a configuration in which an object to be plated and a plating solution are put and a plating operation is performed.

The body portion 11 is formed in a cylindrical shape communicating in both directions and has an inclined surface 132 that is narrowed toward the bottom.

The body portion 11 becomes a main space in which the plated object is placed in the inner space, and the plating solution is filled in the inner space to perform the plating operation.

When described in detail with reference to the drawings, the body portion 11 is formed in a cylindrical shape, and flanges 111 are formed at both ends. A body portion 11 and a cover portion 13 are coupled to the flanges 111 of both ends, respectively. The body portion 11 and the cover portion 13 may be coupled by a fastening member.

Also, at least one pair of grip grooves 112 facing each other are formed on the outer periphery of the body 11 . In this embodiment, two pairs of grip grooves 112 are formed to form a total of four grip grooves 112 . The pair of grip grooves 112 are positioned to face each other. The gripper part 43 of the transfer unit 40 is coupled with the grip groove 112 to facilitate the movement of the plating cell 10 without slipping.

The grip groove 112 is formed by being depressed from the outer periphery of the body portion 11 , and the entrance of the grip groove 112 is formed to be inclined. Accordingly, the gripper part 43 may be coupled to the grip groove 112 while being guided along the inclined surface.

The body portion 11 has an inclined surface 113 whose interior becomes narrower toward the lower portion. The plating cell 10 is rotated to plated the object to be plated inside. During the plating operation, the object to be plated can be arranged in parallel along the inclined surface 113 by centrifugal force during the plating operation, so that the plating can be performed evenly.

The bottom part 12 is made to cover the lower part of the body part 11 to close the lower part, and a plurality of grooves for coupling are formed on the bottom surface. The bottom part 12 is coupled to the mounting part 26 on which the plating cell 10 is placed so that it can be mounted and detached without a separate binding member.

In detail, the bottom part 12 constitutes the lower part of the plating cell 10 . The bottom part 12 is coupled to a seating part 26 to be described later and is placed on the top of the seating part 26 .

A plurality of grooves are formed on the bottom surface of the bottom part 12 to enable mounting and detachment with the seating part 26, and the coupling between the bottom part 12 and the seating part 26 is performed by coupling and magnetic force between the pin and the pin groove. It can be made by bonding by

Specifically, the bottom part 12 includes a first plate 121 and a second plate 122 . The first plate 121 has a conical protrusion 128 formed in the center, and forms a space in which the object to be plated or the plating solution is put together with the body 11 .

If the object to be plated is located in the center during plating, it is not affected by centrifugal force and stays there, and the plating operation is not performed smoothly. The conical protrusion 128 makes it difficult for the object to be plated at the center of the bottom 12, and the plating operation can be smoothly performed while moving outward by centrifugal force.

The second plate 122 is disposed under the first plate 121 and includes a first groove 123 in which the magnetic body 127 is mounted and a second groove 124 coupled to the pin 262 of the seating portion 26 . ) is formed. In this case, a magnet may be mounted in the first groove 123 instead of a magnetic material, and a magnet or a magnetic material may be provided to correspond to the seating portion 26 .

Referring to the drawings, a plurality of first grooves 123 are formed around the center of the second plate 122 and magnetic bodies 127 are coupled thereto. At this time, the second plate 122 is preferably made of a non-magnetic material so that the magnetic force is concentrated on the magnetic material, while the magnetic force can be easily adjusted. In addition, the plating cell 10 is coupled to and detachably from the mounting unit 26 by the magnetic body 127 and the magnet 265 provided on the mounting unit 26 .

Meanwhile, by adjusting the magnetic force by adjusting the number of the first grooves 123 and the number of magnetic bodies 127 coupled to the first grooves 123 , the coupling force between the plating cell 10 and the seating part 26 can be adjusted.

Meanwhile, a plurality of second grooves 124 may be formed around the first groove 123 . A pin 262 provided in the seating portion 26 may be coupled to the second groove 124 . Accordingly, the pin coupling between the mounting portion 26 and the plating cell 10 is achieved. By coupling the second groove 124 and the pin 262 , the plating cell 10 can be placed at the correct position of the seating part 26 . In addition, the rotational driving of the seating portion 26 may be transmitted to the plating cell 10 by the coupling of the pins 262 , so that the plating cell 10 may rotate.

Meanwhile, as illustrated, in the second plate 122 , a third groove 125 and a fourth groove 126 may be formed in addition to the first groove 123 and the second groove 124 .

The third groove 125 is formed in a relatively large area in the center of the second plate 122 and the end of the shaft 271 of the actuator is coupled thereto. In this embodiment, although power transmission is not made by the coupling of the end of the shaft 271 of the actuator and the third groove 125, the end of the shaft 271 of the actuator and the third groove 125 are coupled to the plating cell. (10) is guided to be located in the center.

The fourth groove 126 is formed of a single groove connected in a circular shape to the outside of the second groove 124 . As the fourth groove 126 is formed, the overall weight of the plating cell 10 can be reduced and the plating cell 10 can be rotated quickly even with a small force.

The cover part 13 is made to cover the upper part of the body part 11, is formed in a cylindrical shape communicating in both directions, and has an inclined surface 132 whose outer periphery increases toward the lower part.

In detail, the cover part 13 constitutes the upper part of the body part 11 . Referring to the drawings, the cover part 13 includes an entrance surface 131 , an inclined surface 132 , and an edge surface 133 .

The inlet surface 131 is formed in a cylindrical shape and is a part into which the object to be plated is put. The inclined surface 132 has a shape extending from the entrance surface 131 and increasing toward the lower portion of the periphery. Also, the edge surface 133 extends from the inclined surface 132 , vertically from the end of the inclined surface 132 , and then horizontally to form a stepped groove 134 at the inclined surface 132 .

The step groove 134 prevents the object to be plated from escaping to the outside of the plating cell 10 along with the plating solution or the cleaning solution during plating or cleaning. That is, when there is no step groove 134, the plating solution or the washing solution can move upward along the inner wall surface of the plating cell 10 by centrifugal force, and the object to be plated can also move to the top of the plating cell 10. 134) interferes with this movement.

Meanwhile, as illustrated, a plurality of slit holes 135 may be formed on the entrance surface 131 of the cover part 13 at intervals in the circumferential direction. In addition, a mesh network may be provided in the slit hole 135 . As described above, according to the phenomenon that the plating liquid, the washing liquid, and the object to be plated move upward, some objects to be plated may even reach the entrance surface 131 , but the movement of the object to be plated is mediated through the mesh network of the slit hole 135 . As the plating solution or the washing solution is discharged, the object to be plated may fall to the lower part of the plating cell 10 .

Meanwhile, the cover part 13 may further include a reinforcing plate 136 stacked on the edge surface 133 as shown. The reinforcing plate 136 and the edge surface 133 are integrally coupled to the body 11 . The coupling state of the body portion 11 and the cover portion 13 may be more firmly maintained by the reinforcing plate 136 .

The plating cell 10 configured as described above can be moved by using the transfer unit 40 and can be used by being attached to an apparatus for performing an individual process. Accordingly, the entire process can be automated, and the plating process can be performed quickly.

The plating unit is a configuration in which a plating operation is performed, and the seating part 26, the shaft part 27, and the driving part 28 constituting the mounting unit and the first cover part 21 for performing the plating operation while preventing the liquid from scattering. ), a second cover portion 22, and a sealing portion 23. At this time, the sealing part 23 may have the form of the plating part 24 and the liquid recovery part 25 and may be configured to perform an actual plating operation. Each of these parts may be arranged to be coupled to the frame 60 constituting the skeleton.

The seating part 26 is a part on which the plating cell 10 of the rotary plating apparatus is mounted. Referring to the drawings, the seating part 26 includes a support plate 261 , a pin 262 , a coupling member 263 , and a magnet 265 .

The support plate 261 has a flat plate shape and the plating cell 10 is placed thereon. When the plating cell 10 is placed on the support plate 261 , the upper surface of the support plate 261 and the bottom surface of the plating cell 10 are in contact with each other. A plurality of pins 262 are disposed to protrude from the upper portion of the support plate 261 . These pins 262 are coupled to the plurality of second grooves 124 formed on the bottom surface of the plating cell 10 .

On the other hand, a plurality of magnets 265 are mounted around the center of the support plate 261 to correspond to the magnetic body 127 of the plating cell 10 . At this time, the support plate 261 is preferably made of a non-magnetic material so that the magnetic force is concentrated while the magnetic force is easily controlled.

In addition, one end of the coupling member 263 penetrates through the center of the support plate 261 , protrudes above the support plate 261 , and is coupled to the third groove 125 of the plating cell 10 . The coupling member 263 is coupled to be integral with the support plate 261 , and the other end of the coupling member 263 is coupled to a shaft 271 connected to the driving unit 28 . Accordingly, when the shaft 271 rotates, the support plate 261 also rotates, and the plating cell 10 coupled to the support plate 261 by the pin 262 and magnetic force is rotated.

Meanwhile, one end of the coupling member 263 has a relatively large area and may be formed to be spaced apart from the bottom of the third groove 125 without touching it. In addition, a recessed receiving groove 264 is formed at one end of the coupling member 263 . The coupling member 263 and the shaft 271 may be coupled using a coupling member (not shown) through the receiving groove 264 .

According to this configuration, the seating portion 26 has a shape in which the coupling member 263 protrudes from the center of the support plate 261 , and the pins 262 protrude around the coupling member 263 . Accordingly, the plating cell 10 is stably placed on the support plate 261 while being guided by the coupling member 263 and the pin 262 . At this time, since the support plate 261 and the plating cell 10 are coupled by magnetic force, the coupling is strong while the plating cell 10 can be moved.

On the other hand, since the coupling member 263 is coupled to one end of the shaft 271 to cover the shaft end, and has a shape protruding to the upper portion of the support plate 261 , the plating solution or washing solution dropped on the support plate 261 is applied to the shaft 271 . movement can be prevented.

The shaft portion 27 is coupled to the center of the seating portion 26 to rotate the seating portion 26 . Specifically, one end of the shaft 271 of the shaft portion 27 is coupled to the coupling member 263 of the seating portion 26 . Since the coupling member 263 is coupled to be integral with the support plate 261 , the rotation of the shaft 271 is transmitted to the plating cell 10 through the coupling member 263 and the support plate 261 , and the plating cell 10 rotates. let it do

On the other hand, the shaft portion 27 may be formed by connecting the divided shafts 271 . Referring to the drawings, the shaft portion 27 is composed of two divided shafts 271 , and the two divided shafts 271 are connected to each other by a coupling 272 . At this time, it is preferable to use the coupling 272 having an insulating function.

This is to protect the driving unit 28 . In detail, the cathode (corresponding to the negative electrode) is connected to the divided upper shaft, and the anode (corresponding to the positive electrode) is connected to the plating solution filled in the plating cell 10 to conduct electroplating. If the shaft 271 is divided with the ring 272 interposed therebetween, it is possible to prevent leakage of current used for plating to the driving unit 28, thereby preventing deterioration of plating quality and damage to the driving unit 28 at the same time. can prevent

Meanwhile, the driving unit 28 is connected to the shaft portion 27 and generates power so that the shaft portion 27 rotates. As the driving unit 28, a generally known geared motor may be used.

The first cover part 21 is configured to cover a certain area under the plating cell 10 and may include a receiver 211, a flange 212, and a protrusion 213 to effectively perform this. have.

Referring to FIGS. 3 and 8 , the receptor 211 has an inner cylinder 215 positioned below the plating cell 10 and an outer cylinder 216 that is formed to surround the outer circumference of the inner cylinder 215 , and is a connection surface. The plating solution scattering from the plating cell 10 is received from the bottom through the 217 .

Here, a discharge pipe 214 for discharging the received plating solution scattered from the plating cell 10 may be formed in the receptor 211 .

Referring to the drawings, the lower portions of the outer tube 216 and the inner tube 215 are inclined to have an oval shape, and the connection surface 215 connecting them is also inclined to one side. In addition, since the discharge pipe 214 is formed in the lower part of the inclined connection surface 215 , the plating solution contained in the receptor 211 is naturally discharged to the discharge pipe 214 by its own weight.

In this case, it is preferable that the inner diameter of the outer cylinder 216 be larger than the outer periphery of the plating cell 10 , and the inner diameter of the inner cylinder 215 is smaller than the outer circumference of the lower portion of the plating cell 10 . With this structure, the lower edge of the plating cell 10 is positioned between the outer tube 216 and the inner tube 215 , and the scattered plating solution is received in the container 211 as a whole.

A shaft 27 connected to the driving unit 28 passes through the center of the inner cylinder 215 and is coupled to the mounting unit 26 on which the plating cell 10 is placed.

The flange 212 protrudes from the end of the outer tube 215 of the receiver 211 in a direction perpendicular to the outer tube 215 and is placed on the work table 50 . As the flange 212 is placed on the workbench, the first cover part 21 may be mounted on the workbench 50 .

Meanwhile, the protrusion 213 protrudes from the flange 212 toward the opposite direction to the receptor 211 at a predetermined height and forms a closed curved surface. The upper portion of the protrusion 213 is in contact with the second cover portion 22 so that the periphery of the plating cell 10 is blocked from the outside. By making the upper portion of the protrusion 213 and the second cover portion 22 (the flange 222 of the second cover portion) in contact with each other, a stable space closure is possible.

On the other hand, the second cover part 22 is configured to cover the upper region where the plating cell 10 is disposed, and has a space in which both ends are open, the cover body 221 , the flange 222 and the assembly 223 . Including, as a whole, is made of a dome shape with an open top.

A connecting member 225 is coupled to the outside of the cover body 221 , and a certain point of the connecting member is axially rotatably coupled while an end of the connecting member 225 is rotatably connected by a cylinder rod. Accordingly, when the cylinder 226 is operated, the connecting member 225 is rotated about its axis while the end is raised or lowered, and the cover body 221 coupled to the connecting member also rotates to surround the upper periphery of the plating cell 10 . It is driven to cover or release the covered state.

Meanwhile, in the cover body 221 , a discharge pipe 224 for discharging gas generated from the plating cell 10 and filled in the cover body 221 during plating may be formed.

The flange 222 is formed to protrude from one side of the cover body 221 in a direction perpendicular to the cover body 221 , and when the cover body 221 covers the plating cell 10 , the bottom surface of the flange 222 is the first. 1 is brought into contact with the cover part 21 . At this time, the end of the cover body 221 is positioned between the inner tube 215 and the outer tube 216 of the first cover part 21 . On the other hand, a plurality of guide blocks 228 are provided on the upper portion of the flange 222 so that the cover body 221 is placed in an accurate position.

The coupling body 223 is formed to protrude from the other side of the cover body 221 , and a hole having an inclined surface 229 that becomes narrower in the direction of the cover body 221 is formed. The sealing part 23 is coupled to this hole so that the upper space of the plating cell 10 is completely sealed.

Meanwhile, the sealing part 23 is driven to seal the open hole in the upper part of the second cover part 22 and has a flow path through which the plating solution or the cleaning solution can move. The sealing part 23 includes a movable body 231 , a pressing body 232 , and an action body 233 , and can act as a plating part 24 , a liquid recovery part 25 , and a washing part 31 to be described later. have.

The movable body 231 can move in two or three dimensions, so that the action body 233 can be positioned above the hole of the second cover part 22 or the pressing body 232 can be moved to be coupled to the hole. The movable body 231 is capable of two-dimensional movement by a vertical actuator and a rotation actuator located under the work table 50 . Specifically, the movable body 231 can be moved to the upper part of the hole of the second cover part 22 by rotational driving, and can be moved to be coupled to the hole of the second cover part 22 by a vertical actuator.

The pressing body 232 is coupled to the movable body 231 with an elastic member 234 interposed therebetween, and when the second cover part 22 is covered to surround the upper periphery of the plating cell 10, the second cover part 22 ) is coupled to the open hole in the upper part and pressurized. When the sealing part 23 is moved downward a predetermined distance in a state coupled to the hole, the elastic member 234 is deformed so that the sealing part 23 is in close contact with the groove.

Meanwhile, the pressing body 232 may have an inclined surface, and a sealing member 235 may be provided on the inclined surface. The sealing member 235 may be mounted with a groove formed on the inclined surface. Since the inclined surface 229 corresponding to the open hole of the above-described second cover part 22 is also formed, the pressing body 232 and the second cover part 22 can be coupled to each other while the sealing member is in close contact between the inclined surfaces. .
