Description

Plating device with smart control of plating jig {PLATING DEVICE WITH SMART CONTROL OF PLATING JIG}

The present invention relates to a plating device that deposits a plated body in a plating liquid and applies a current to allow the plating components on the plating liquid to be plated onto the plated body. Specifically, the plating conditions for various plated bodies can be implemented respectively, and the plated body This relates to technology that improves safety and problem detection in plating operations.

Plating is a process of coating a thin film of plating ingredients on the surface of a plated object. Plating is performed for protection such as decoration, rust prevention, and corrosion prevention by coating the plated body with a plating component of gold or conductive base metal.

Plating methods include electroplating, chemical plating, and hot dip plating. Among these, electroplating uses the principle of electrolysis to electrolytically deposit a thin film of another metal on the surface of the material by setting the plated object to be plated as the cathode and then applying a direct current to correspond to it.

Electroplating is used in various fields such as the automobile industry (automotive parts), audio equipment, aircraft, information and communication equipment, computer parts, accessories, and the construction industry. The plating components of electroplating mainly include gold, silver, copper, and nickel, and can be used in small to large amounts, and can express the texture of various metals.

When such electroplating is performed in large quantities, the plated body is deposited in a plating solution in which the above-mentioned plating components are electrolyzed, and plating is performed by applying a direct current to the plated body. The problem at this time is that the plating components are not evenly positioned in the plating bath. Alternatively, the plated body may not be plated evenly depending on its shape and the type of current application during plating in the plating bath.

To solve this problem, for example, in Korean Patent Application No. 10-2019-0168490, etc., a rotating jig is installed in the plating tank and the plated body is placed on it to perform plating, so that plating is evenly performed as the plated body rotates in the plating tank. We are publishing the technology that allows you to do this.

However, in the above prior art, since the jig is rotated while fixed in the plating tank, the plating solution must be removed from the plating tank to take out the plated body after completion of plating of the plated body seated in the jig, which makes the process very complicated and causes damage to the plated body. There is a problem in that it is difficult to perform plating on a plated body according to various conditions through diversification of rotation and power application.

Accordingly, the present invention was developed to solve the above problems, and in the electroplating method of immersing the plated body in the plating bath while seated in the jig, the desired electroplating is achieved through precise automatic control of the rotation of the jig and the applied current. The purpose is to provide technology that can ensure uniform plating quality on all plated bodies.

In addition, the present invention allows individual plating conditions to be set and controlled for multiple plating jigs, thereby enabling plating under various plating conditions at the same time, thereby improving productivity and improving convenience and stability during the plating process. There is another purpose in providing technology that can be used.

In order to achieve the above objectives, a plating device capable of smart control of a plating jig according to an embodiment of the present invention has a tip capable of hanging a plurality of plating bodies, which is formed in multiple layers radially with respect to a central axis and is supplied with current. A jig body composed of a conductor that supplies current to the plated body and plating the plated body when the plating liquid is deposited; A rotation motor having a drive shaft coupled to the central axis of the jig body and rotating the drive shaft in both directions to rotate the jig body in both directions about the central axis; a control box in which the rotation motor is installed, and controlling the rotation time, rotation direction, and rotation speed of the rotation motor, and the intensity and current supply time of the current applied to the jig body; And a plating tank that accommodates the jig body and accommodates a plating solution.

The control box controls the rectifier that supplies current to the jig body to control the intensity of the current applied to the jig body and the current supply time, and the drive shaft is configured to enable up and down reciprocating movement in the direction toward the plating bath. And when the drive shaft moves and the jig body is seated to be accommodated in the plating bath, it is possible to automatically control the current supply to supply current to the jig body through the rectifier.

A current sensor that senses the current of the jig body is included, and the control box controls the rectifier by detecting changes in the current value of the current sensor, so that the plating body settles in the plating solution in the plating tank and is plated on the plating body. In this case, it is possible to allow the current to be continuously applied.

The control box is installed in multiple numbers so that a control box is connected to each jig body so that multiple jig bodies can be installed in the plating bath, and the rotation time, rotation direction, and rotation of each jig body are controlled through individual control of each control box. It is possible for the speed, intensity of current applied to each jig body, and current supply time to be individually controlled.

A sealing slit is formed in each unit area of each plating bath to enable the installation of a blocking film between each area of the plating bath where each jig body is seated, so that when the blocking film is installed in the sealing slit, the plating solution is separated between the unit areas of each plating bath. It is possible to make supply available.

The control box may be configured so that a plurality of control boxes are connected to one control terminal so that the plurality of control boxes can be individually controlled through the one control terminal.

It is possible to further include a sensor unit including a load sensor for sensing the load of the jig body and a current sensor for sensing the current of the jig body.

The control box is information received from the sensor unit, and the load of the jig body changes by exceeding a preset first rate during rotation of the jig body, or the current of the jig body exceeds a preset second rate. If there is a change, it is possible to determine a work abnormality and control the rotation motor and the rectifier to stop the rotation of the jig body and the current supply, and output problem notification information through a notification means installed in the control box. do.

The uppermost side of the central axis of the jig body and the drive shaft of the rotation motor are configured to be engaged with each other, so that the jig body and the rotation motor can be attached and detached.

According to the present invention, a rotary jig is implemented by a jig coupled to the rotary motor in a control box where the rotary motor is installed, and the rotary motor and the jig body are implemented to be detachable, so that the installation of the plating body seated on the jig is possible. and separation has the effect of being implemented very easily.

In addition, by installing a rotation motor in each of the multiple control boxes, plating can be performed in one plating bath, and thus the rotation conditions of each of the multiple control boxes and the current application conditions for plating can be controlled. At the same time, it has the effect of improving productivity by enabling plating under various plating conditions.

In addition, in implementing precise plating quality uniformly on all plated bodies, the jig is driven only when it is accurately seated in the plating tank through current and load detection, which can greatly improve convenience and stability during the plating process. It works.

It would be natural to understand that the scope is not limited.

Additionally, in the following description, multiple drawings will be simultaneously referred to and described in order to explain components constituting one technical feature or invention.

When described with reference to the above drawings, a plating device capable of smart control of a plating jig according to an embodiment of the present invention includes a jig body 10, a rotation motor 20, a control box 30, and a plating tank 50. ) is characterized in that it includes.

In the present invention, the plating bath 50 has a barrel-shaped structure that accommodates the plating solution in which the plating body is deposited together as the jig body 10 settles and the plated body is hung and seated on the tip 11 of the jig body 10. refers to As described above, the plating tank 50 contains a plating solution in which the plating components to be plated are dissolved. When the plating material is deposited and an electric current is applied to the plating material, the plating components in the plating solution are transferred to the plated body by electrolytic action. to bind to the surface.

As described above, the jig body 10 has tips 11 on which a plurality of plated bodies can be hung, and is formed in multiple layers in a radial direction with respect to the central axis, and is composed of a conductor that supplies current, thereby supplying current to the plated bodies. It is configured to perform the function of plating the plated body when the plating liquid is deposited. That is, the jig body 10 is configured to rotate in the R direction about a central axis so as to be rotatable in both directions, as will be described later, and a plurality of tips 11 are formed radially about the central axis, forming a team ( 11) It is configured so that the plated body can be hung and seated.

As the jig body 10 is made of a conductor as described above, when current is applied to the jig body 10, the current is applied to the plating body by contact with the tip 11. That is, the jig body 10 is formed with a tip 11 so that the plated body can be mechanically hung, and a current can be electrically applied to the plated body.

In the present invention, the number and spacing of tips 11 can be configured in various ways depending on the plating body, and the length of the central axis of the jig body 10 can also be configured in various ways depending on the plating body and the depth of the plating tank 50. It can be. Additionally, the shape of the tip 11 may vary depending on the shape and size of the plated body placed on the tip 11.

In the present invention, the plating body is seated on the tip 11 as shown in the drawings to allow plating to be performed, and depending on the shape of the tip 11, it is draped over the top of the tip 11 or is placed on the tip 11. Depending on the configuration, it can be fixed to the tip 11 in various ways, such as being inserted into a binding site formed by the tip 11.

The plating bath 50 contains a plating solution, which contains metal components such as gold, silver, and nickel to be plated on the surface of the plated body. Accordingly, when current is applied to the jig body 10 and applied to the plated body, the plated body is attached to the surface of the plated body through electrolysis to perform plating.

The jig body 10 excludes the contact area or point between the tip 11 and the plating body and the external power supply area to allow current to be applied to the plating body for plating the plating body with the above-mentioned plating solution. May be covered with insulation.

The rotation motor 20 is configured to have a drive shaft 21 coupled to the central axis of the jig body 10, and rotate the drive shaft 21 in both directions to rotate the jig body 10 in both directions about the central axis. am. The rotation motor 20 is driven by receiving power from an external power source. At this time, the external power source will be understood as the same power source that applies current to the jig body 10 described above. The external power supply can apply power to the rotation motor 20 and at the same time rectify the power into direct current through the rectifier 40, thereby applying direct current for plating to the jig body 10.

The rotation motor is a motor for rotating the drive shaft 21 in both directions, and can be understood as an AC motor that is driven in the forward or reverse direction depending on the control input of the applied power. According to this two-way rotation, as described above, the jig body 10 can also be rotated in both directions (R) in the forward and reverse directions, thereby minimizing the occurrence of deviation in plating thickness during the plating process. At this time, the rotation speed, rotation direction, rotation time, etc. are matched to the identification information of the plated body according to a specific input from the outside through the control box 30, which will be described later, or an identification input for the plated body, and are stored in the plating processor in advance. It is automatically determined according to conditions such as automatic rotation speed, rotation direction, and rotation time, and the driving of the rotation motor 20 can be controlled accordingly.

Meanwhile, in the present invention, a sub-drive means such as a servomotor is installed to enable the rotation motor 20 itself or the drive shaft 21 to move up and down, thereby moving the rotation motor 20 or the drive shaft 21 up and down. The jig body 10 can be removed from the plating tank 50 or brought into a settled state.

In addition, as shown in Figures 1 to 3, etc., in another embodiment of the present invention, a hanging hook 12 is formed on the uppermost side of the central axis of the jig body 10, and the driving shaft 21 of the rotation motor 20 A locking groove 22 is formed on the bottom side, so that the drive shaft 21 of the rotation motor 20 and the central axis of the jig body 10 are locked with each other. According to this, the jig body 10 and the rotation motor 20 can be detached, so that there is no need to remove the plating body from the tip 11 after removing all the plating solution in the plating bath 50, and the jig body 10 After being separated from the plating tank 50, the plating body can be conveniently removed.

This effect can be further maximized through a configuration that allows the jig body 10 to move up and down as described above. That is, since the jig body 10 can be more easily separated from the drive shaft 21 according to the vertical movement of the rotation motor 20 or the drive shaft 21, plating can be performed after conveniently separating the jig body 10. By removing the sieve, convenience in the post-plating process can be maximized.

The control box 30 is a hardware and software configuration including a control unit 33, which will be described later. Specifically, as shown in the drawings, a rotation motor 20 is installed inside, and the rotation motor 20 operates. It performs the function of controlling the time, direction of rotation, rotation speed, intensity of current applied to the jig body 10, and current supply time through control of the rectifier 40.

At this time, the above-described vertical movement means of the rotation motor 20 and the drive shaft 21 are installed in the control box 30, or in another embodiment of the present invention, the sub-drive means moves the control box 30 itself up and down. It can be configured as follows.

The control box 30 can be connected to an external input means to control the operation of the rotation motor 20 and the rectifier 40. At this time, the external input means is an input means through a button or LED touch screen installed on the control box 30, or an interface and input such as an external terminal connected to the control unit 33 of the control box 30 through wired or wireless communication as described later. refers to means.

As shown in FIGS. 1 and 2, the control box 30 is installed on each jig body 10 to individually control the jig body 10. That is, it is possible to control the rotational speed, direction, and time of each jig body 10, and the voltage and current intensity and time of the DC power supply applied to the jig body 10.

Specifically, the control box 30 controls the rectifier 40 that supplies current to the jig body 10 to control the intensity of the current applied to the jig body 10 and the current supply time. Meanwhile, the drive shaft 21 is configured to enable up and down reciprocating movement in the direction toward the plating bath by the sub-drive means as described above. At this time, the control box 30 moves the drive shaft 21 to move the jig body 10. When seated to be accommodated in the plating tank 50, current supply can be automatically controlled to supply current to the jig body 10 through the rectifier 40.

As described above, there are various embodiments that automatically supply current to the jig body 10 through the rectifier 40 while the jig body 10 is accommodated in the plating tank 50 and the plating process can be performed. It can be implemented like this:

For example, a current sensor 32 may be installed on the jig body 10 or the drive shaft 21, as shown in FIG. 3. The current sensor 32 is configured as shown in FIG. 3 to sense the current applied to the drive shaft 21, for example, or senses the current applied to the jig body 10 through other configurations.

At this time, the control box 30 detects changes in the current value of the current sensor 32 and controls the rectifier 40, so that the plating body 200 settles in the plating solution 100 in the plating tank 50, forming the plating body ( When plating is performed on 200), the rectifier 40 can be controlled so that current is continuously applied. At this time, it is possible to control the interruption or continuation of the plating process by determining an abnormality in the plating according to the change in the current value of the current sensor 32.

For example, referring to Figure 6, when the plating body 200 is normally seated on the jig body 10, the plating solution 100 is applied through the plating body 200 to perform plating. Therefore, the measured current value and the current value measured when a part of the plated body 200 is not properly seated may vary depending on the number and seating state of the plated body 200 and the jig body 10.

Accordingly, the control box 30, that is, the control unit 33, when the current of the jig main body 10 fluctuates by exceeding the preset second ratio (for example, 10%), determines that the work is abnormal and controls the jig main body ( 10), the rotation motor 20 and the rectifier 40 can be controlled to stop rotation and current supply, and problem notification information can be output through the notification means 31 installed in the control box 30. At this time, the notification means 31 may be composed of a display device or a speaker, and may output notification information as visual or auditory information.

Meanwhile, such work abnormalities can be determined by sensing the current, but can also be determined by other methods that can sense the case where the plating body 200 is not properly seated on the jig body 10. In other words, monitoring the working status can be implemented in a manner other than the current sensing described above.

For example, in addition to the current sensor 32 (S1) in FIG. 6, a load sensor (S2) may be installed. That is, in another embodiment of the present invention, a sensor unit including a load sensor (S2) that senses the load of the jig body (10) and a current sensor (32, S1) that senses the current of the jig body (10) may be further included. You can.

At this time, the control box 30, that is, the control unit 33, is information received from the sensor unit, and the load of the jig main body 10 is adjusted to a preset first ratio (for example, 10%) during rotation of the jig main body 10. or, as described above, if the current of the jig body 10 changes more than the preset second ratio (for example, 10%), it is judged to be a work abnormality and the jig body 10 rotates and The rotation motor 20 and the rectifier 40 can be controlled to stop the current supply, and problem notification information can be output through the notification means 31 installed in the control box 30.

Meanwhile, as described above, the control box 30 detects changes in the current value of the current sensor 32 and controls the rectifier 40, so that the plating body 200 is in the plating solution 100 in the plating tank 50. When plating is deposited on the plated body 200, the rectifier 40 can be controlled so that the current is continuously applied. Through this, an operator may accidentally inadvertently deposit the plated body 200 on the jig body 10. By starting plating while mounting, it is possible to completely prevent safety accidents such as electric shock to workers through the plating body 200 or safety accidents due to rotation of the jig body 10.

Meanwhile, in one embodiment of the present invention, as shown in FIG. 2, the control boxes (30-1, 30-2, and 30-3) are connected to each jig body (10-1, 10-2, and 10-3). , a plurality of control boxes (30-1, 30-2, 30-3) can also be installed so that a plurality of jig bodies (10-1, 10-2, 10-3) can be installed in the plating bath (50). there is. In this case, the rotation time, rotation direction, and rotation speed of each jig body (10-1, 10-2, 10-3) are controlled through individual control of each control box (30-1, 30-2, 30-3). The intensity and current supply time of the current applied to each jig body (10-1, 10-2, and 10-3) can be individually controlled.

Through this, it is possible to control the rotation conditions of each of the multiple control boxes and the current application conditions for plating, thereby improving productivity by simultaneously enabling plating under various plating conditions.

At this time, when controlling each of the multiple control boxes (30-1, 30-2, 30-3), the driving conditions are controlled through the input means on the outside of the control box as described above, or the driving conditions are controlled through an external terminal connected to it. It can be. In order to enable more integrated control in control through an external terminal, as shown in FIG. 5, the control box includes a plurality of control boxes (30-1, 30-2, and 30-3). It may be configured to be connected to the control terminal 60 so that a plurality of control boxes 30-1, 30-2, and 30-3 can be individually controlled through one control terminal 60.

According to the above-mentioned, the rotation speed, rotation direction, rotation time, current intensity, current application time, etc. of each jig body 10 are controlled in the same plating tank 50, so that plating under various conditions is possible even with the same plating solution. It has a dissolving effect.

In addition, the plating solution itself can be configured in various ways. That is, in another embodiment of the present invention, as shown in FIG. 4, a sealing slit 51 is formed in each unit area of the plating bath 50, preferably in each area where each jig body 10 is accommodated. A blocking film 52 may be inserted into the sealing slit 51 to block the movement of the plating solution in each unit area of the plating tank 50 through the blocking film 52 and the sealing slit 51. In this case, when the blocking film 52 is installed in the sealing slit 51, it becomes possible to individually supply the plating solution between unit areas of each plating tank 50. According to this, there is an effect that more diverse plating conditions can be implemented in one plating device.

As described above, although the embodiments have been described with limited examples and drawings, those skilled in the art will understand that various modifications and variations can be made from the above description. Terms such as “include,” “comprise,” or “have” described above mean that components that are not specifically stated to the contrary may be included, and therefore do not exclude other components, but rather include other components. It should be interpreted to include more. In addition, the scope of protection of the present invention should be interpreted in accordance with the claims below, and all technical ideas within the equivalent scope should be construed as being included in the scope of rights of the present invention.
