Description

Conductive device and horizontal electroplating equipment
Technical Field
The application belongs to the technical field of electroplating and electric conduction, and particularly relates to an electric conduction device and horizontal electroplating equipment.
Background
The horizontal plating technique is a plating method in which a workpiece to be plated is placed parallel to the surface of a plating solution. The basic principle of horizontal electroplating is approximately the same as that of ordinary electroplating, and the horizontal electroplating comprises a cathode and an anode, wherein the cathode is generally used for contacting a workpiece to be plated, and the anode is used for introducing electricity into electroplating liquid; in this way, electrode reaction can occur in the electroplating solution after the power is on, and under the action of an electric field, metal ions in the electroplating solution migrate to the vicinity of the cathode, so that a plating layer is formed on a workpiece to be plated. The horizontal electroplating has the characteristics of convenient operation, wide range of adapting to the size of the workpiece, convenient large-scale automatic operation, closed operation and the like, and has rapid development in recent years and gradually develops towards the mature technology direction with higher quality and higher reliability.
In some existing electroplating equipment, a workpiece to be plated is clamped by a clamp and runs horizontally in an electroplating bath, and the workpiece to be plated is connected with a cathode of an external power supply through the clamp so as to be in contact with the workpiece to be plated for conduction; anode materials are respectively arranged at the upper side and the lower side of the workpiece to be plated at intervals, the anode materials are connected with the positive electrode of the rectifier to lead the positive electrode into the electroplating solution, so that an electric field is formed between the anode materials and the positive electrode, the electroplating solution in the electroplating tank performs electroplating reaction on the surface of the workpiece to be plated, various film layers are generated, and the electroplating effect is realized. The method has the defects of low efficiency, generally only a small amount of workpieces can be mounted, and the mounting and mounting process is time-consuming and labor-consuming.
In addition, in other conventional electroplating devices, a workpiece to be plated can be horizontally conveyed through a transmission mechanism, and the transmission mechanism generally comprises a roll shaft, wherein the workpiece to be plated is clamped between an upper roll shaft and a lower roll shaft; the roll shaft can be provided with a certain number of conductive rollers which are connected with cathodes at two ends of the roll shaft and are directly contacted with a workpiece to be plated so as to realize the connection of negative electrode electricity. Similarly, anode materials are respectively arranged at the upper side and the lower side of the workpiece to be plated at intervals, the anode materials are connected with the anode to lead the anode into the electroplating liquid, so that an electric field is formed between the anode materials and the anode, the electroplating liquid in the electroplating tank performs electroplating reaction on the surface of the workpiece to be plated, various film layers are generated, and the electroplating effect is realized. The disadvantage of this method is that, because the workpiece to be plated is sandwiched between the two rollers, and the conductive roller is conductive to contact with the workpiece, a certain pressure is applied, so that the gap between the rollers needs to be strictly controlled to be consistent, otherwise, the workpiece is extremely fragile to be damaged or deformed. In addition, during the electroplating process, the cathode or the related conductive parts immersed in the electroplating solution can be plated with a coating layer along with the electroplating, and the coating layer on the cathode or the related conductive parts can cause cracking, damage or other flaws of a workpiece to be plated, damage to equipment and effective components of the electroplating solution. In order to avoid the above phenomenon, most of the current horizontal electroplating equipment needs to stop electroplating frequently so as to independently unhook the cathode to finish periodic maintenance, thus the operation is complicated, and the electroplating efficiency is affected.

Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1 to 12, in some embodiments of the present application, a conductive device is provided, which may be applied in the field of electroplating, such as in a horizontal electroplating apparatus, for implementing conductivity, such as implementing conductivity of a cathode, and may be used in other apparatuses, where the specific use scenario and working condition of the conductive device are not particularly limited.
As shown in fig. 1 to 10, in some embodiments, the conductive device includes a plurality of conductive rollers 10, and the number of conductive rollers 10 may be one or more, preferably a plurality, and the number of conductive rollers 10 is preferably an even number, and each conductive roller 10 includes: a roller assembly, a conductive assembly 120, and an electrode assembly 130. The roller assembly includes a roller 100 adapted to rotate, the roller 100 being capable of being driven by a driving mechanism, the roller 100 being capable of being mounted and supported, for example, by mounting the conductive assembly 120 and the electrode assembly 130 to one end of the roller 100. The roller assembly further comprises a plurality of groups of roller brushes 101 arranged on the roller 100, and optionally, a plurality of groups of roller brushes 110 are arranged on the roller 100 along the axial direction of the roller 100; for example, a plurality of sets of roller brushes 110 are provided on the outer circumference of the roller 100, and each set of roller brushes 110 (may also be referred to as each row of roller brushes) is uniformly distributed at intervals along the axial direction of the roller 100. The electrode assembly 130 is configured to electrically connect to a power source and to conduct electricity to the conductive assembly 120, and the conductive assembly 120 is configured to conduct electricity to the roller brush 110 on the roller 100, wherein the roller brush 110 is configured to contact the workpiece 40 to be plated so as to apply the conducted electricity (particularly, negative electricity) to the workpiece 40 to be plated.
Specifically, the conductive assembly 120 is located at one end of the roller 100, and the conductive assembly 120 includes a plurality of conductive contacts 121, each conductive contact 121 is electrically connected to each set of roller brushes 110, and the plurality of conductive contacts 121 are adapted to rotate along with the rotation of the roller 100. In this embodiment, a plurality of conductive contacts 121 independent of each other are provided, and each conductive contact 121 is matched with the corresponding roller brush 110, so that each set of roller brushes 110 is independent of each other, and each set of roller brushes 110 can be respectively electrically contacted with the workpiece 40 to be plated. When the roller 100 rotates, the plurality of conductive joints 121 can rotate along with the rotation of the roller 100, and the roller brushes 110 arranged on the roller 100 can also rotate along with the rotation of the roller, so that a plurality of groups of roller brushes 110 can be sequentially and electrically contacted with the workpiece 40 to be plated. The number of the conductive contacts 121 needs to correspond to the number of the groups of the roller brushes 110, and the number of the conductive contacts 121 or the number of the groups of the roller brushes 110 can be selected and set according to actual requirements, which is not limited in this embodiment; illustratively, the number of conductive contacts 121 may be 2-20, or 4-16, or 6-12, etc.
Alternatively, each conductive contact 121 may be electrically connected to each set of roller brushes 110 by a wire. Of course, in order to electrically connect the conductive contact 121 and the roller brush 110, other manners may be adopted, which is not limited in this embodiment.
One end of the conductive member 120 may be connected to the roll 100, and one end of the conductive member 120 facing away from the roll 100 may be provided with an electrode assembly 130. The electrode assembly 130 includes first and second electrodes 131 and 132 having opposite polarities, that is, one of the first and second electrodes 131 and 132 is used to be connected to a negative electrode of a power source and the other is used to be connected to a positive electrode of the power source. For example, the first electrode 131 is connected to a negative electrode of a power source, and the second electrode 132 is connected to a positive electrode of the power source; or the first electrode 131 is connected to the positive electrode of the power supply, and the second electrode 132 is connected to the negative electrode of the power supply. For simplicity, the first electrode 131 is mainly connected to the negative electrode of the power supply, and the second electrode 132 is connected to the positive electrode of the power supply. The first electrode 131 and the second electrode 132 may be used to make electrical contact with the respective conductive contacts 121 of the conductive assembly 120, respectively, so as to achieve the effect of simultaneously stripping the plating film on the roller brush 110 during the electroplating process of the workpiece 40 to be plated.
Alternatively, the power source includes a rectifier, which may also be referred to as a plating power source. In general, a rectifier, when used for a process such as electrolysis or plating, can function as a power supply device, which is mainly a device for adjusting the current, voltage, or the like of a standard input power supply. Thus, one of the first electrode 131 and the second electrode 132 may be electrically connected to the negative electrode of the rectifier, and the other may be electrically connected to the positive electrode of the rectifier.
Alternatively, the relative positions of the first electrode 131 and the second electrode 132 may be maintained as the drum 100 rotates. That is, in the present embodiment, the conductive assembly 120 may rotate with the rotation of the drum 100, and the electrode assembly 130 may remain stationary while the drum 100 rotates.
During operation of the conductive device, the roller 100 is driven by the driving mechanism to rotate, and as the roller 100 rotates, the plurality of conductive contacts 121 may rotate and sequentially electrically contact the first electrode 131 and the second electrode 132, i.e., the conductive contacts 121 may be switched between being electrically connected to the first electrode 131 and being electrically connected to the second electrode 132, and at any one time, the polarities of at least one set of roller brushes 110 and at least one other set of roller brushes 110 are opposite. For example, at any one time, at least one conductive tab 121 is electrically connected to the first electrode 131, so that at least one set of the roller brushes 110 correspondingly connected to the conductive tab 121 becomes a cathode roller brush, while at least another conductive tab 121 is electrically connected to the second electrode 132, so that at least one set of the roller brushes 110 correspondingly connected to the conductive tab 121 becomes an anode roller brush. In this embodiment, the roller brush 110, which is a cathode roller brush, is in contact with the workpiece 40 to be plated, and the cathode roller brush may be used to be matched with an anode in the device, and the workpiece 40 to be plated is electroplated under the action of an electric field, so as to form a coating layer, such as various metal film layers, on the workpiece 40 to be plated. It will be appreciated that, typically, during electroplating, the roller brush 110 will be immersed in the electroplating solution, and therefore, during electroplating of the workpiece 40 to be plated, the roller brush 110 will also be plated with metal, i.e., will be plated with a coating. In this embodiment, at least one other set of roller brushes 110 is an anode roller brush while the workpiece 40 to be plated is being plated, and the anode roller brush and the cathode roller brush also interact, so that a coating layer (such as various metals) attached to the anode roller brush can be dissolved in the plating solution, that is, the effect of stripping or hanging the coating layer on the anode roller brush can be achieved; as the drum 100 rotates continuously, the coating layer attached to each set of the roller brushes 110 can be unhooked.
Thus, based on the above arrangement, in this embodiment, through the mutual matching of the first electrode 131, the second electrode 132, the plurality of conductive joints 121 that are arranged independently of each other, and the plurality of sets of roller brushes 110 that are arranged independently of each other, one of the electrodes is mainly used to be electrically connected with the roller brush 110 through the conductive joint 121, so that the roller brush 110 becomes a cathode roller brush, and the cathode roller brush contacts with the workpiece 40 to be plated and interacts with the anode in the device, so as to realize the electroplating of the workpiece 40 to be plated; meanwhile, in order to reduce or avoid the puncture or damage of the workpiece 40 to be plated or the waste of the plating solution caused by the metal deposition generated on the roller brush 110 of the conductive roller 10 during the plating process, the other electrode is electrically connected with the other roller brush 110 through the other conductive connector 121, so that the roller brush 110 becomes an anode roller brush, and the metal adhered to the anode roller brush can be dissolved in the plating solution, namely, the automatic stripping can be realized. Therefore, the damage to the workpiece or equipment to be plated by the coating layer on the conductive roller 10 can be reduced or avoided, the waste of the electroplating liquid can be reduced, the metal attached to the roller brush 110 of the conductive roller does not need to be independently unhooked when electroplating is stopped, the operation is simple, the time and the labor are saved, the electroplating quality is improved, and the electroplating efficiency and the production yield are also improved. In addition, the whole electroplating and deplating process can be realized in the electroplating bath without additionally arranging a deplating bath or a deplating device, so that the structure of the whole horizontal electroplating device is simplified, the occupied space of the device is reduced, the cost is reduced, the manpower is saved, and the maintenance is convenient.
According to the present embodiment, the roller 100 of the conductive roller 10 can rotate, so that the workpiece 40 to be plated in the plating tank 20 can be guided to run, that is, the conductive roller 10 can serve as a horizontal transmission mechanism and a cathode conductive mechanism simultaneously, which plays a role in both transmission of the workpiece 40 to be plated and cathode conduction of the workpiece 40 to be plated.
The roller brush 110 on the conductive roller 10 can rotate along with the rotation of the roller 100, so that the roller brush 110 can switch between positive and negative electrodes, that is, the roller brush 110 connected with the negative electrode can be a cathode roller brush, and the roller brush 110 connected with the positive electrode can be a part of an anode roller brush which can be used as an anode, thereby realizing the effect of plating a workpiece to be plated and simultaneously stripping a plating film layer attached on the conductive roller.
As shown in fig. 2 to 4, in some embodiments, the conductive assembly 120 further includes a conductive mounting frame 122, the conductive mounting frame 122 is connected to one end of the roller 100, the conductive joints 121 are uniformly arranged on the conductive mounting frame 122, and the conductive mounting frame 122 is adapted to be driven to rotate along with the rotation of the roller 100, so as to drive the conductive joints 121 disposed on the conductive mounting frame 122 to rotate, so that the conductive joints 121 are electrically connected to the first electrode 131 and electrically connected to the second electrode 132. The conductive assembly 120 includes a conductive mounting frame 122 and a plurality of conductive contacts 121, where the conductive mounting frame 122 can provide mounting positions for the plurality of conductive contacts 121, and perform functions such as mounting and supporting.
In order to realize that the plurality of conductive joints 121 rotate along with the rotation of the roller 100, the embodiment is further provided with a conductive mounting frame 122, and the conductive mounting frame 122 is connected to one shaft end of the roller 100 by arranging the conductive joints 121 on the conductive mounting frame 122, and the conductive mounting frame 122 and the roller 100 synchronously rotate to realize the rotation of the plurality of conductive joints 121; that is, the conductive mounting frame 122 can be driven to rotate along with the rotation of the roller 100, and thus the conductive joints 121 on the conductive mounting frame 122 can be driven to rotate.
The diameter of the side end of the conductive mounting frame 122 for connection with the roll 100 needs to be adapted to the diameter of the roll 100 so that the side end of the conductive mounting frame 122 is cooperatively connected with the roll 100.

In this embodiment, each pair of conductive rollers 10 may share a driving motor to drive, and the two conductive rollers 10 in each pair of conductive rollers 10 may be linked by the transmission mechanism 140 to act together to horizontally transmit the workpiece 40 to be plated.
As shown in fig. 2, in some embodiments, a shaft sleeve 150 is sleeved on the rotating shaft 101, and the rotating shaft 101 is in transmission connection with the conductive mounting frame 122 in the conductive assembly 120 through the shaft sleeve 150. Alternatively, the conductive mounting frame 122 may be provided with a rotation shaft hole through which the rotation shaft 101 in the drum 100 may be connected to the conductive mounting frame 122.
In order to realize synchronous rotation of the conductive mounting frame 122 and the conductive connectors 121 arranged in the conductive mounting frame 122 with the roller 100, the rotating shaft 101 arranged in the roller 100 is connected with the conductive mounting frame 122 through the shaft sleeve 150, and the rotating shaft 101 is driven to rotate by the driving mechanism, so that the conductive mounting frame 122 and the conductive connectors 121 arranged in the conductive mounting frame 122 can be driven.

In some embodiments, the roller brush 110 is made of a flexible material. The flexible roller brushes on the roller 100 may be evenly staggered around the surface of the roller 100.
A certain number of roller brushes 110 are distributed on the peripheral surface of the roller 100, and the roller brushes 110 are flexible roller brushes, so that the roller brushes 110 can be in flexible contact with the workpiece 40 to be plated when in contact with the workpiece 40 to be plated, and damage to the workpiece 40 to be plated is reduced or avoided. The material for manufacturing the roller brush 110 may be a material which is flexible and can recover the original state after no stress, for example, may be metal fiber, carbon fiber, or other materials with similar properties, and the specific manufacturing material of the roller brush 110 is not limited in this embodiment.
Alternatively, as shown in fig. 1-3 or fig. 10, in some cases, the roller brushes 110 are in rolling friction contact with the workpiece 40 to be plated, for example, each set of roller brushes 110 may rotate along with the rotation of the roller 100, and the roller brushes 110 serving as cathode roller brushes may be in rolling friction contact with the workpiece 40 to be plated, for example, by adjusting the rotation speed of the roller 100 and/or the running condition of the workpiece 40 to be plated, so that the two sets of roller brushes are in rolling friction contact with each other while maintaining a relative movement trend.

As shown in fig. 11 to 12, in some embodiments, the present application further provides a horizontal plating apparatus, which includes a plating tank 20 and the aforementioned conductive device disposed in the plating tank 20.
The horizontal electroplating apparatus of the present embodiment includes the above-mentioned conductive device, and thus has at least all the features and advantages of the conductive device, which are not described herein.
In the horizontal electroplating apparatus, the electroplating tank 20 may include a tank body, in which a conductive device is disposed, and an electroplating solution is further disposed. Alternatively, other structures such as a driving device may be disposed in the plating tank 20, and the driving device may be used to drive the workpiece 40 to be plated to horizontally run in the plating tank 20. The specific arrangement and operation principle of the other parts such as the driving device in the plating tank 20 can be referred to in the prior art, and this embodiment is not limited thereto.
As shown in fig. 11 or 12, in some embodiments, the conductive device includes a plurality of pairs of conductive rollers 10 arranged horizontally, each pair of conductive rollers 10 includes two conductive rollers 10 arranged at intervals in a vertical direction to form a through-piece passage through which the workpiece 40 to be plated horizontally passes, that is, the two conductive rollers 10 are configured such that the workpiece 40 to be plated passes between the two conductive rollers 10, and at least one set of roller brushes 110 in the conductive rollers 10 corresponding to the workpiece 40 to be plated is in contact with the workpiece 40 to be plated; in operation of the horizontal plating apparatus, the plating bath 20 is provided with a plating solution, and at least a portion of each pair of conductive rollers 10 is immersed in the plating solution, such as the roller brush 110 on the conductive roller 10. Optionally, an anode assembly is disposed in the electroplating solution, the anode assembly includes a first anode 210 and a second anode 220 disposed at intervals, the first anode 210 and the second anode 220 are respectively located above and below each pair of conductive rollers 10, and the first anode 210 and the second anode 220 are connected to the positive electrode of the power supply. Alternatively, the power supply includes a rectifier, and the first anode 210 and the second anode 220 may be connected to the positive poles of the rectifier.
The plating tank 20 is provided with a plating solution, and a first anode 210 and a second anode 220 are disposed in the plating solution, wherein the first anode 210 may be located above each conductive roller 10 in the vertical direction of the conductive rollers 10, the second anode 220 may be located below each conductive roller 10, and the first anode 210 and the second anode 220 may sandwich each conductive roller 10 and other transmission mechanisms such as the transmission roller 30.
During electroplating, the first anode 210 and the second anode 220 are connected with the positive electrode of an electroplating power supply, one of the first electrode 131 and the second electrode 132 in the electrode assembly 130 is connected with the negative electrode of the power supply as an electroplating anode, the roller brush 110 connected with the anode is used as an electroplating cathode, the electroplating liquid is used as an electroplating medium to form an electroplating loop, and the workpiece 40 to be electroplated is electroplated under the action of the generated electric field, namely, a coating film is formed on the surface of the workpiece 40 to be electroplated. Also, at the time of plating, at least a portion of the conductive roller 10 is immersed in the plating solution, for example, the roller 100 and the roller brush 110 of the conductive roller 10 may be immersed in the plating solution, and the electrode assembly 130 and the conductive contacts 121 of the conductive roller 10 may not contact the plating solution.
Further, according to the present embodiment, since at any one time, at least one conductive tab 121 is connected to one of the electrodes in contact with the positive electrode, while at least one conductive tab 121 is connected to the other electrode in contact with the negative electrode. On the other hand, when a certain conductive connector 121 is electrically contacted with the electrode connected with the negative electrode, the conductive connector becomes the negative electrode, so that the roller brush 110 correspondingly connected with the conductive connector becomes a cathode roller brush, and the cathode roller brush contacts with the workpiece 40 to be plated and is matched with the first anode 210 and/or the second anode 220 in the electroplating solution to form a current loop, thereby realizing the process of coating the surface (single-sided or double-sided) of the workpiece 40 to be plated. On the other hand, in the process of electroplating the workpiece 40 to be plated, the roller brush 110 is also electroplated with metal, and when some other conductive connector 121 is in electrical contact with the electrode connected with the positive electrode, a part of the positive electrode is formed, so that the roller brush 110 correspondingly connected with the conductive connector becomes an anode roller brush, and the anode roller brush is used as a part of the anode and interacts with the cathode roller brush to form a current loop, thereby realizing the process of stripping the metal attached on the surface of the anode roller brush. As the drum 100 rotates continuously, the metal film layer attached to each set of the roller brushes 110 can be unhooked. That is, from the viewpoint of the same set of the roller brushes 110, when they come into contact with the negative electrode to become the cathode roller brushes, the workpiece 40 to be plated is plated, itself is plated, and when the set of the roller brushes 110 comes into contact with the other electrode (electrode connected to the positive electrode) as the roller 100 rotates to become the anode roller brushes, the metal adhered thereto is dissolved in the plating solution.
Typically, the current of the electroplating process will be greater than the current of the deplating process, and therefore, the interaction of the anode and cathode brushes does not affect the cathode brushes to communicate with the first anode 210 or the second anode 220 in the electroplating solution and effect the electroplating process. That is, the present embodiment achieves the effect of deplating the metal attached to the roller brush 110 of the conductive roller 10 on the premise of achieving the electroplating of the workpiece 40 to be plated.
Alternatively, the first anode 210 and the second anode 220 may be an upper anode plate and a lower anode plate, respectively, which may be supported on the inner wall of the tank body of the electroplating tank 20. Optionally, the upper anode plate and the lower anode plate may be connected to the positive electrode of the rectifier through copper flat or wires, respectively.
Alternatively, in the horizontal plating apparatus, the cathode of the rectifier may be connected to the first electrode 131 or the second electrode 132 of one (one) conductive roller 10 of each pair of conductive rollers, or may be connected to the first electrode 131 or the second electrode 132 of both conductive rollers 10 of each pair of conductive rollers, thereby achieving single-sided or double-sided plating of the workpiece 40 to be plated; that is, one rectifier may be connected to one conductive roller, or one rectifier may be connected to both conductive rollers of a pair of conductive rollers. Of course, in order to achieve single-sided or double-sided plating of the workpiece 40 to be plated, other means may be adopted, for example, when cathodes of two rectifiers are connected to both conductive rollers 10 of each pair of conductive rollers, single-sided or double-sided plating may be achieved by controlling the switches of the rectifiers, so that flexibility of the plating operation process may be improved.
As shown in fig. 12, in some embodiments, a plurality of horizontally arranged driving rolls 30 are further disposed in the plating tank 20, each of the driving rolls 30 includes two driving rolls 30 disposed at intervals in a vertical direction, and the two driving rolls 30 are configured such that the workpiece 40 to be plated passes between the two driving rolls 30; at least one pair of driving rollers 30 is provided between two adjacent pairs of conductive rollers 10, for example, a pair of driving rollers 30 or two or more pairs of driving rollers 30 may be provided between two adjacent pairs of conductive rollers 10.
The electroplating tank 20 is internally provided with a plurality of pairs of conductive rollers 10 and a plurality of pairs of driving rollers 30, and the pairs of conductive rollers 10 and the pairs of driving rollers 30 can play a role in driving the workpiece 40 to be plated so as to enable the workpiece 40 to be plated to horizontally move in the electroplating tank 20. This further facilitates the operation of the workpiece 40 to be plated. Each pair of the driving rollers 30 and each pair of the conductive rollers 10 may be alternately arranged along the driving direction of the workpiece 40 to be plated. Since a certain distance exists between each driving roller 30 and the next driving roller 30, and each pair of conductive rollers 10 is arranged between the driving rollers 30 to play a role in driving the workpiece 40 to be plated, the workpiece 40 to be plated is prevented from being deviated due to too far distance between each driving roller 30, and the guiding and driving functions are played for the operation of the workpiece 40 to be plated.
It should be noted that the number of pairs of the conductive rollers 10 and the number of pairs of the driving rollers 30 disposed in the plating tank 20 may be set according to actual needs, which is not limited in this embodiment.

In particular, the metal adhered to the anode roller brush can be dissolved in the electroplating solution while the workpiece 40 to be plated is electroplated, so that the effect of stripping or hanging the metal coating on the anode roller brush can be realized; with the continuous rotation of the roller 100 in the conductive roller 10, the coating layer attached to each set of roller brushes 110 can be unhooked. That is, on the one hand, the conductive rollers 10 rotate, and the upper and lower conductive rollers 10 in each pair of conductive rollers 10 can help the workpiece 40 to be plated to drive; on the other hand, the conductive roller 10 may be rotated as power for switching the positive and negative electrodes by rotating the roller brushes 110 of each group, so that the roller brush 110 connected with the negative electrode and serving as the cathode roller brush changes polarity in a rotating manner to become the anode roller brush after completing the conduction of the workpiece 40 to be plated and the attachment of metal, the anode roller brush and the cathode roller brush interact to achieve the effect of stripping or hanging the coating layer on the anode roller brush, and the electroplating process can also be performed. Thus, when the electroplating is stopped, the metal attached to the roller brush 110 of the conductive roller 10 is not required to be independently unhooked, so that frequent unhooking actions are reduced, and the maintenance is convenient. The operation is simple, the time and the labor are saved, the electroplating quality is improved, and the electroplating efficiency and the production yield are also improved. In addition, the whole electroplating and deplating process can be realized in the electroplating tank 20 without additionally arranging a deplating tank or a deplating device, so that the structure of the whole horizontal electroplating device is simplified, the occupied space of the device is reduced, the cost is reduced, the manpower is saved, and the maintenance is convenient.
