However, the provision of the flattening rollers excessively increases the overall volume of the plating apparatus, making the plating apparatus excessively expensive to manufacture.

Referring to fig. 1 to 3, according to an embodiment of the present utility model, there is provided an electroplating apparatus including a binder device.

The clamping device comprises a clamping mechanism 30, the clamping mechanism 30 comprises a fixed seat 31, a rotating seat 32, a first clamping wheel 33 and a second clamping wheel 34, the rotating seat 32 is rotatably arranged on the fixed seat 31, the first clamping wheel 33 and the second clamping wheel 34 are arranged on the rotating seat 32 at intervals, a gap for a preset film to pass through is formed between the first clamping wheel 33 and the second clamping wheel 34, and at least one of the first clamping wheel 33 and the second clamping wheel 34 is a conductive wheel.

Specifically, when the electroplating device is used for electroplating the film, the edge of the film is arranged between the gaps of the first clamping wheel 33 and the second clamping wheel 34 in a penetrating way, at least one of the first clamping wheel 33 and the second clamping wheel 34 is a conductive wheel, and the film is used as the cathode for electroplating. Meanwhile, by adjusting the rotation of the rotating seat 32, the first clamping wheel 33 and the second clamping wheel 34 have a certain angle relative to the width direction of the film, namely, the first clamping wheel 33 and the second clamping wheel 34 can flatten the film, so that the film is prevented from collapsing towards the middle area of the film.

Compared with the prior art, the edge clamping device of the embodiment has the edge clamping conductive effect, can flatten the film, and integrates the existing edge clamping conductive wheel and the flattening roller, so that the problems that the size of electroplating equipment is increased, and the manufacturing cost of the electroplating equipment is too high are avoided.

Further, one of the first clamping wheel 33 and the second clamping wheel 34 is a conductive wheel, and the other is an insulating wheel.

In this embodiment, the first clamping wheel 33 or the second clamping wheel 34 can be used as a cathode in electroplating when being a conductive wheel, and both the first clamping wheel 33 and the second clamping wheel 34 are partially immersed in the electroplating solution during electroplating. Therefore, when the film is coated, a coating is generated on the conductive wheel, and if the first clamping wheel 33 and the second clamping wheel 34 are both conductive wheels, the first clamping wheel 33 and the second clamping wheel 34 are both coated, so that the gap is too small, the film is easily stressed too much, and the film is damaged.

In order to coat the plating layers on the surfaces of the upper side and the lower side of the film, and the plating layers on the two sides are relatively uniform. In the present embodiment, the clamping mechanisms 30 include a plurality of clamping mechanisms 30 arranged at intervals along the first direction (X direction in fig. 3); the first clamping wheels 33 of two adjacent clamping mechanisms 30 are conductive wheels and insulating wheels in sequence along the first direction, and the second clamping wheels 34 of two adjacent clamping mechanisms 30 are conductive wheels and insulating wheels in sequence.

Specifically, along the first direction, the first clamping wheels 33 in the plurality of clamping mechanisms 30 are sequentially conductive wheels and insulating wheels for circulation, and the second clamping wheels 34 in the plurality of clamping mechanisms 30 are sequentially insulating wheels and clamping wheels for circulation, so that the current density of the upper layer and the lower layer of the film is uniform, and the thickness of the coating is uniform.

In addition, a rotating assembly is provided on the rotating base 32, and the rotating assembly is used for adjusting the rotation angle of the first clamping wheel 33 and/or the second clamping wheel 34.

In this embodiment, the flattening of the edge clamping device is achieved by applying a force to the film away from the middle region of the film, and if too little force is applied, the film will still collapse toward the middle region, resulting in wrinkling of the film. If the applied external force is too large, the film is pulled and deformed and the film is torn and broken. Therefore, in the present embodiment, the magnitude of the flattening force to which the film is subjected is adjusted by adjusting the angle between the first or second sandwiching wheel 33 or 34 and the film. Specifically, when the film is clamped between the first clamping wheel 33 and the second clamping wheel 34 and forms a certain angle, the clamping device rotates to apply a force in the radial direction of the first clamping wheel 33 or the second clamping wheel 34 to the film, the component force of the force in the width direction of the film is a flattening force, and the angle between the clamping device and the film is adjusted, so that the flattening force is adjusted, and the film is not pulled to deform or tear to break the film, and is not collapsed towards the middle area of the film.

Further, the rotating assembly comprises a rotating main shaft 35, a first connecting shaft 36 and a second connecting shaft 37. The rotating main shaft 35 is fixedly arranged on the rotating base 32 and is rotatably connected to the fixed base 31. One end of the first connecting shaft 36 is connected to the rotating main shaft 35 and is perpendicular to the rotating main shaft 35, and the first clamping wheel 33 is rotatably sleeved on the first connecting shaft 36. One end of the second connecting shaft 37 is connected to the rotating main shaft 35 and is perpendicular to the rotating main shaft 35, the second connecting shaft 37 and the first connecting shaft 36 are arranged at intervals along the length direction of the rotating main shaft 35, and the second clamping wheel 34 is rotatably sleeved on the second connecting shaft 37.

In a specific embodiment, the rotating main shaft 35 extends in the height direction (Z direction in fig. 1), the rotating shaft is disposed on top of the fixing base 31, and the first clamping wheel 33 is disposed on top of the second clamping wheel 34. When the rotating main shaft 35 rotates, the rotating main shaft 35 drives the rotating seat 32 to rotate, and simultaneously the rotating main shaft 35 also drives the first connecting shaft 36 and the second connecting shaft 37 to rotate, so as to drive the first clamping wheel 33 and the second clamping wheel 34 to synchronously rotate, and finally, the rotation angle of the first clamping wheel 33 and the second clamping wheel 34 is adjusted.

Of course, in some embodiments, the rotating assembly is coupled to either the first pinch wheel 33 or the second pinch wheel 34 to control the relative rotation angle of either the first pinch wheel 33 or the second pinch wheel 34 for applying a flattening force to the film.

Further, the rotating assembly further includes a locking part (not shown in the drawings) including a locking hole provided on the fixed seat 31 and a locking member penetrating the locking hole and having a locking position against the rotating spindle 35 and an adjusting position releasing the rotating spindle 35.

Specifically, the locking member in this embodiment includes a bolt, and the extending direction of the locking hole is perpendicular to the axial direction of the rotation main shaft 35. When it is necessary to adjust the rotation angle of the first and second chuck wheels 34, the bolts are loosened and the rotating main shaft 35 is released. Then, after rotating the rotary spindle 35 to a proper position, the bolt is tightened to a locking position, thereby preventing the rotary spindle 35 from rotating.

Further, the rotating base 32 includes a support section 322 and a flange section 321, the support section 322 is disposed perpendicular to the flange section 321, the rotating main shaft 35 is disposed perpendicular to the flange section 321, and the first connecting shaft 36 and the second connecting shaft 37 penetrate through the support section 322.

Specifically, the flange section 321 is disposed at the bottom of the support section 322, and the flange section 321 and the support section 322 are disposed in an L-shape, and the first and second pinch wheels 33 and 34 are disposed at a side of the support section 322 away from the flange section 321. The support section 322 can provide support to the first and second connection shafts 36 and 37, preventing the first and second connection shafts 36 and 37 from moving in a vertical direction under the force of gravity.

Further, a first elongated through hole 323 is disposed on the rotating base 32, the length direction of the first elongated through hole 323 is consistent with the length direction of the rotating main shaft 35, the first connecting shaft 36 is disposed in the first elongated through hole 323 in a penetrating manner, a first limiting hole 324 and a first limiting member 325 are disposed on the rotating base 32, the first limiting hole 324 is communicated with the first elongated through hole 323, and the first limiting member 325 is disposed in the first limiting hole 324 in a penetrating manner and is connected with the first connecting shaft 36 to limit the first connecting shaft 36 in the first elongated through hole 323.

Specifically, the first limiting hole 324 of the present embodiment includes a bolt, which is loosened before the coating is performed. The film is then placed between the gaps of the first and second pinch wheels 33, 34, after which the bolts are tightened, causing the first and second pinch wheels 33, 34 to apply a preload force to the film, thereby clamping the film between the first and second pinch wheels 33, 34. In a specific embodiment, the first connecting shaft 36 is provided with a through hole adapted to the first limiting member 325, so as to connect the first limiting member 325, and when the first limiting member 325 is unscrewed, the first connecting shaft 36 can be driven to move along the height direction.

In addition, an angle scale assembly (not shown) is provided on the rotary spindle 35 in some embodiments for specifying the current rotation angle of the first and second pinch wheels 33 and 34.

Meanwhile, in the plating apparatus of the present embodiment, the plating apparatus includes a plating tank 10, a stripping tank 20. Wherein the plating tank 10 is used for plating a thin film. The stripping tank 20 is disposed at two sides of the plating tank 10, and is used for stripping the metal adhered on the edge clamping device, and the edge clamping device is disposed in the stripping tank 20.

Specifically, the film is electroplated with a metal layer by the electroplating solution in the electroplating tank 10, and the edge clamping device is also affected by the electroplating solution, so that the edge clamping device is electroplated with metal. However, the stripping solution in the stripping tank 20 can cause the metal electroplated on the edge clamping device to be stripped, so that the influence of the metal deposited on the edge clamping device on the film coating quality is avoided to a certain extent.

In one embodiment of the present embodiment, the stripping solution stored in the stripping tank 20 can strip the metal attached to the edge clamping device. Specifically, the thin film is a conductive thin film, and the plating solution is a liquid that flows into the plating solution tank 20 after the plating of the plating solution. In operation of the plating apparatus of this embodiment, the thin film is immersed in the plating solution and electrically connected to the anode portion 11 in the plating tank 10, and the edge nipping device is brought into contact with the thin film as a cathode, so that metal ions in the plating solution are reduced to metal and deposited on the thin film, thereby forming a metal layer. Meanwhile, in this embodiment, there are two stripping tanks 20, and edge clamping devices are respectively disposed in the two stripping tanks 20, the edge clamping devices conduct electricity to two ends of the film, and the edge clamping devices are immersed in the stripping solution. When the film is electroplated, the edge clamping device is used as a cathode of the electroplating tank 10 under the action of the stripping solution, so that the edge clamping device is attached with metal. However, since the edge clamping device serves as an anode in the plating stripping tank 20, the metal deposited on the edge clamping device is re-plated into ions, thereby avoiding the metal deposited on the edge clamping device to have an influence on the film coating quality to some extent.

Further, an anode portion 11 is provided in the plating vessel 10. The plating bath 20 is provided with an auxiliary cathode portion 21. The plating tank 10 is provided with a first power source (not shown) and a second power source (not shown), and the anode of the first power source is connected to the anode portion 11, and the cathode of the first power source is connected to the edge clamping device. The positive electrode of the second power supply is connected to the edge clamping device, and the negative electrode of the second power supply is connected to the auxiliary cathode portion 21.

Specifically, in the plating tank 10, the edge clamping device serves as a cathode, so that metal is plated on the edge clamping device, and in the electroless plating tank 20, the edge clamping device serves as an anode, so that metal deposited on the edge clamping device is electroless plated. Meanwhile, the relative speed of electroplating and deplating on the edge clamping device can be changed by controlling the current of the first power supply and the second power supply, so that metal can not be deposited on the edge clamping device.

Further, referring to fig. 5, a first thin film passage 12 through which a thin film passes is provided between the plating tank 10 and the plating tank 20, two anode portions 11 are included in this embodiment, and the two anode portions 11 are disposed in order on the upper side and the lower side of the first thin film passage 12 in the height direction of the plating tank 20. This indicates that both sides of the film can be plated with a metal layer during film plating. The first film passage 12 in this embodiment allows the film edge to pass through the plating tank 10 and enter the stripping tank 20, so that the edge clamping device can supply power to the edges of the two ends of the film, and the first film passage 12 can also supply the electrolyte in the plating tank 10 to enter the stripping tank 20.

Further, the anode portion 11 includes an anode plate including a plurality of anode sub-plates, and the plurality of anode sub-plates are connected to the positive electrode of the first power supply.

Specifically, the anode plate is a structural member formed by splicing a plurality of anode sub-plates on the same horizontal plane, and the anode sub-plates are connected with the positive electrode of the power supply, so that the current density distribution of the film is more uniform at all positions when the film is coated. In one embodiment, the anode plate is a titanium plate. When the titanium plate is used as an electroplating anode, the titanium plate is insoluble in electrolyte, and the service life is long. In this embodiment, the auxiliary cathode portion 21 is also a titanium plate, and the titanium plate is stable in chemical properties when used as a cathode, and therefore can be used for a long period of time. It should be noted that, since the auxiliary cathode portion 21 is continuously electroplated with metal, the stripping effect of the edge clamping device in the stripping tank 20 is affected, and therefore, when the electroplating apparatus is actually operated, the auxiliary cathode portion 21 needs to be replaced after a certain period of use. Meanwhile, in the present embodiment, the metal ions may be provided by an electrolyte, for example, a copper sulfate solution may be used as the plating solution in the case of plating the copper layer. Alternatively, in the present embodiment, the titanium plate of the anode portion 11 may be replaced with titanium blue and a metal ball.

As shown in fig. 8, an overflow tank 40 is provided on the side of the plating tank 20 away from the plating tank 10, and an overflow passage 41 is provided at the bottom of the side of the plating tank 20 close to the overflow tank 40. Specifically, the plating solution in the plating bath 20 can flow into the overflow vessel 40 through the overflow channel 41 and out of the plating apparatus in the overflow vessel 40, avoiding excessive plating solution in the plating bath 20. In the present embodiment, a mounting passage is provided on the side wall between the overflow tank 40 and the plating tank 20 for mounting the auxiliary cathode portion 21, and the mounting passage is provided between the driving member and the overflow passage 41. Further, in order to prevent the driving member from coming into contact with the deplating solution, the driving member is provided in the overflow vessel 40 with a predetermined distance from the bottom surface of the overflow vessel 40 in the height direction of the plating apparatus. It should be noted that the predetermined distance in this embodiment is a distance higher than the highest level of the plating solution in the overflow trough. In addition, the overflow path 41 is provided at the bottom of the side of the plating bath 20 near the overflow bath 40, preventing the plating bath from overflowing from the upper end of the side wall of the plating bath 20, thereby affecting the driving part.

Further, the bottom of the overflow tank 40 is communicated with the bottom of the plating tank 10 through a return passage (not shown), and a control member (not shown) for controlling the on-off of the return passage is provided on the return passage.

Specifically, the solution outlet 42 of the overflow tank 40 is communicated with the return channel, the total inlet 13 of the plating tank 10 is communicated with the return channel, and as shown in fig. 3 to 6, a plurality of shunt ports 15 extending along a direction perpendicular to the film conveying direction are further provided in the plating tank 10 at intervals, and the shunt ports 15 are communicated with the total inlet 13, so that the plating solution entering the plating tank 10 is uniformly mixed throughout the plating tank 10. Meanwhile, a plating solution outlet 14 is formed in the bottom of the plating tank 10 for controlling the level of the plating solution in the plating tank 10. Still further, in operation of the plating apparatus of the present utility model, the plating solution is continuously replenished from the total solution inlet 13 at the bottom of the plating tank 10, and the replenished plating solution moves upward from the bottom of the plating tank 10 and is fully mixed with the plating solution in the plating tank 10, and when reaching the position of the thin film passage, plating with the thin film occurs, and then part of the plating solution overflows into the plating solution tank 20 through the first thin film passage 12. At this time, the concentration of the liquid in the stripping tank 20 is lower than that of the liquid in the electroplating tank 10, which is more favorable for stripping by the edge clamping device. When the edge clamping device is used for deplating, part of the deplating solution flows into the overflow groove 40 through the overflow channel 41, finally flows into the reflux channel through the deplating solution outlet 42 and is refluxed into the electroplating tank 10 under the control of the control component, thereby realizing the circulation of the plating solution and reducing the consumption of the plating solution.

Further, along the working direction of the electroplating apparatus, both sides of the electroplating tank 10 are provided with a transition tank 50, the transition tank 50 is provided with a second film channel 51 for passing a film, the second film channel 51 is communicated with the first film channel 12, and a transmission component 52 for transmitting the film is arranged in the transition tank 50.

Specifically, the film enters one transition tank 50 through the second film passage 51, is transferred into the plating tank 10 for plating under the action of the transfer assembly 52 of the transition tank 50, and then enters the transition tank 50 at the other end after the plating is completed, and leaves the plating apparatus through the second film passage 51 under the action of the transfer assembly. Wherein the working direction refers to the transport direction of the film. The transport assemblies 52 on both sides of the transition tank 50 serve to transport and support the film in the operating direction of the plating apparatus. Meanwhile, the transfer assembly 52 may be provided as a tension roller for adjusting the tension of the film. Similarly, a tension detecting device may be further disposed in the transition groove 50 to detect the tension of the film so as to adjust the tension of the film. Alternatively, the conveyor assembly may be a idler.

On the other hand, a plurality of electroplating devices of the embodiment can be connected in series for electroplating, and metal layers with different thicknesses can be electroplated on the film according to different numbers of electroplating devices.

Spatially relative terms, such as "above … …," "above … …," "upper surface on … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In addition, the terms "first", "second", etc. are used to define the components, and are only for convenience of distinguishing the corresponding components, and the terms have no special meaning unless otherwise stated, and therefore should not be construed as limiting the scope of the present utility model.

The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
