Description

Technical Field

[0001] The present application relates to the field of electroplating, and particularly to a conductive clip conveying and opening / closing device and a coating machine. Background Art

[0002] At present, lithium-ion batteries have been widely used. Lithium-ion batteries have the advantages of large capacity, small volume, and light weight.

[0003] A current collector refers to a structure for collecting current. In a lithium-ion battery, it mainly refers to the matrix metal on the positive or negative electrode of the battery for attaching active substances, such as copper foil, aluminum foil, etc. Its main function is to collect the current generated by the battery active substances so as to form a larger current for external output. When manufacturing the current collector, a relatively thick metal coating is usually formed on a conductive base film by electroplating to ensure the conductivity of the current collector. Specifically, a coating machine can be used to electroplate the conductive base film.

[0004] When using a coating machine for coating, a conveyor belt can be used to drive a conductive clip to move. The conductive clip clamps the conductive base film to make the conductive base film enter and exit the plating solution tank. The general process of the conductive clip clamping and conveying the conductive base film is as follows: The conductive clip is in an open state before entering the plating solution tank, and then switches from the open state to the closed state to clamp the conductive base film; then the conductive clip is driven by the conveyor belt into the plating solution tank and moves in the plating solution tank. At this time, the conductive clip is always in the clamping state. When the conductive clip clamps the conductive base film and leaves the plating solution tank, the conductive clip switches from the clamping state to the open state to release the clamping of the conductive base film. Therefore, the conductive clip needs to frequently switch between the open state and the closed state during this process. If manually controlled, the operation is inconvenient, and the opening position and the closing position cannot be accurately controlled, and the labor cost will also increase. Summary of the Invention

[0005] In view of the above deficiencies in the prior art, the present invention provides a conductive clip conveying and opening / closing device and a coating machine, which can enable the conductive clip to automatically clamp or automatically release at a preset position, with convenient operation and labor cost savings.

[0006] To achieve the above object, in a first aspect, the present invention discloses a conductive clip conveying and opening / closing device, including: a conductive clip, the conductive clip includes a fixed clamping arm and a movable clamping arm, the fixed clamping arm is movably connected to the movable clamping arm, a guiding portion is provided on the movable clamping arm, and the movable clamping arm can move relative to the fixed clamping arm in the vertical direction to make the conductive clip in a clamping state or an open state; a conveying device for driving the conductive clip to move along a preset trajectory; a guide rail arranged along the moving path of the conductive clip. When the guiding portion cooperates with the guide rail, the movable clamping arm is lifted by the guide rail to open the conductive clip. When the guiding portion is disengaged from the guide rail, the movable clamping arm falls under the action of gravity to close the conductive clip.

[0007] The above-mentioned fixed clamping arm is movably connected to the movable clamping arm, and the movable clamping arm can move vertically relative to the fixed clamping arm. Therefore, under the action of gravity, the movable clamping arm can move downward relative to the fixed clamping arm, so that the conductive clip can be in a closed state. In addition, the conveying device can drive the conductive clip to move along a preset trajectory, and the guide rail is arranged along the moving path of the conductive clip. Thus, when the conductive clip moves along the preset trajectory and the guiding part arranged on the movable clamping arm cooperates with the guide rail, the guiding part will drive the movable clamping arm to lift, making the movable clamping arm move upward relative to the fixed clamping arm, so that the conductive clip is opened. When the conductive clip continues to move along the preset trajectory and the guiding part disengages from the guide rail, the movable clamping arm can move downward under the action of gravity, so that the conductive clip is closed again. Therefore, in actual use, only by arranging the guide rail at a preset position on the moving path of the conductive clip, the opening position and closing position of the conductive clip can be accurately controlled, that is, arranging the guide rail at the position where the conductive clip needs to be opened and not arranging the guide rail at the position where the conductive clip needs to be closed.

[0008] In a possible implementation manner of the first aspect, the fixed clamping arm includes a fixed rod arranged in the vertical direction and a first clamping part arranged at the lower end of the fixed rod and extending in the horizontal direction. The movable clamping arm includes a movable rod arranged in the vertical direction and a second clamping part arranged at the lower end of the movable rod and extending in the horizontal direction. The fixed rod is fixedly connected to the conveying device, the movable rod is movably connected to the fixed rod, the second clamping part is located above the first clamping part, and the guiding part is arranged on the movable rod. When the guiding part cooperates with the guide rail, the movable rod is lifted by the guide rail to drive the second clamping part to separate from the first clamping part. When the guiding part disengages from the guide rail, the movable rod and the second clamping part fall under the action of gravity, so that the second clamping part fits with the first clamping part. Thus, through the cooperation between the guiding part and the guide rail, the movable rod can be lifted or lowered, so that the conductive clip is opened or closed.

[0009] In a possible implementation manner of the first aspect, the guiding part is a guiding wheel, and the guiding wheel is in rolling cooperation with the guide rail. The rolling cooperation can make the guiding wheel and the guide rail in rolling contact, with less frictional resistance, thereby reducing the wear between the guiding wheel and the guide rail.

[0010] In a possible implementation manner of the first aspect, the movable rod is movably connected to the fixed rod through a rocker assembly. The rocker assembly includes a first rocker and a second rocker that are parallel to each other. One end of the first rocker is hinged to the fixed rod, and the other end is hinged to the movable rod. One end of the second rocker is hinged to the fixed rod, and the other end is hinged to the movable rod. The fixed rod, the movable rod, the first rocker, and the second rocker form a parallelogram planar linkage mechanism. In the above parallelogram planar linkage mechanism, the movable rod can swing reciprocally relative to the fixed rod, so that the conductive clip can be in a clamping state or an open state.

[0011] In a possible implementation of the first aspect, the upper surface of the guide rail is a guiding surface, which includes an ascending inclined surface and a descending inclined surface arranged in sequence along the moving track of the conductive clip. When the guiding part cooperates with the ascending inclined surface, the movable clamping arm is gradually lifted, causing the conductive clip to gradually open. When the guiding part cooperates with the descending inclined surface, the movable clamping arm gradually descends under the action of gravity, causing the conductive clip to gradually close. Thus, the arrangement of the ascending inclined surface and the descending inclined surface enables the conductive clip to gradually loosen the clamping of the conductive base film or gently clamp the conductive base film, avoiding sudden changes in the clamping force of the conductive clip, reducing the contact tension, and thereby preventing deformation of the conductive base film. Also, it avoids the large impact force generated by the rapid descent of the movable rod, thus preventing damage to the conductive base film caused thereby.

[0012] In a possible implementation of the first aspect, the guiding surface further includes a horizontal guiding surface connected between the ascending inclined surface and the descending inclined surface. When the guiding part cooperates with the horizontal guiding surface, the movable clamping arm is maintained in the open state. Thus, the conductive clip can be kept in the open state during the process of preparing for the next clamping after loosening the conductive base film, so that the conductive clip can directly switch to the clamping state when moving to the preset position where it needs to close, saving time.

[0013] In the second aspect, the present invention further provides a coating machine, including the conductive clip transmission opening and closing device of the first aspect.

[0014] In the coating machine provided by the present invention, due to the adoption of the conductive clip transmission opening and closing device of the first aspect, during the coating process, when the conductive clip moves along the preset track, it can realize the switching between the automatic clamping and loosening states of the conductive clip, with a simple and practical structure, cost saving, and improvement of the coating efficiency of the coating machine.

[0015] In a possible implementation of the second aspect, the conductive clip transmission opening and closing device includes: a first conveyor belt and a second conveyor belt, which are respectively arranged on both sides of the plating solution tank and both extend along the first direction; a first conductive clip and a second conductive clip, there are multiple first conductive clips, and the multiple first conductive clips are arranged along the first direction on the first conveyor belt, and multiple second conductive clips are arranged along the first direction on the second conveyor belt. The first conductive clip and the second conductive clip are respectively used to clamp the opposite two side edges of the horizontally placed conductive base film and drive the conductive base film to horizontally enter and exit the plating solution tank along the first direction; a first guide rail and a second guide rail, the first guide rail and the second guide rail are symmetrically arranged on both sides of the plating solution tank along the midline in the width direction of the plating solution tank. The first guide rail is used to cooperate with the first conductive clip to guide the opening or closing of the first conductive clip, and the second guide rail is used to cooperate with the second conductive clip to guide the opening or closing of the second conductive clip.

[0016] Thus, during electroplating operations, multiple conductive clips are driven by a conveyor belt to move in the Y direction. When the conductive base film needs to enter the plating bath for coating, the conveyor belt drives the conductive clips to move to a preset position, enabling the conductive clips to cooperate with the guide rails so that the conductive clips close, clamping the conductive base film from both sides and driving the conductive base film to move in the Y direction. At the same time, an electric current is applied to the conductive base film for electroplating. When the conductive base film completes coating and leaves the plating bath and moves to a preset position, the guide rails cooperate with the conductive clips again so that the conductive clips open and release the clamping of the conductive base film. Moreover, when coating in a coating machine with a horizontal film running mode, the entire conductive base film clamped by the first conductive clip and the second conductive clip is inside the plating bath, thereby avoiding the occurrence of electric breakdown due to the decrease in cooling effect when a part of the conductive base film is outside the plating bath.

[0017] In a possible implementation manner of the second aspect, the first guide rail includes a first guiding section and a second guiding section. The first guiding section corresponds to the inlet side of the plating bath, and the second guiding section corresponds to the outlet side of the plating bath. When the first conductive clip slides along the first guiding section, the first guiding section guides the first conductive clip to close. When the first conductive clip slides between the first guiding section and the second guiding section, the first conductive clip is in a normally closed state. When the first conductive clip slides along the second guiding section, the second guiding section guides the first conductive clip to open. Thus, the first guide rail can guide the first conductive clip to switch between the automatic closing and releasing states when moving to a preset position.

[0018] In a possible implementation manner of the second aspect, the first conveyor belt is an oval conveyor belt, and the first guide rail is an unclosed oval guide rail. The oval guide rail is arranged around the oval conveyor belt, and the oval guide rail has a disconnection part, and the disconnection part corresponds to the position of the plating bath. The setting of the oval conveyor belt enables the first conveyor belt to drive multiple first conductive clips to make an oval rotation, so that the first conductive clips can be continuously recycled. The unclosed oval guide rail enables the first conductive clips making an oval rotation to be in a closed state only at the position of the disconnection part, and the disconnection part corresponds to the position of the plating bath. Therefore, the first conductive clips can clamp the conductive base film to perform coating in the plating bath.

[0019] In a possible implementation manner of the second aspect, the length of the disconnection part in the first direction is greater than the length of the plating bath. Thus, the conductive clips are in a clamped state before entering the plating bath and can open only after leaving the plating bath, avoiding the contact between the clamping surface of the conductive clips and the plating solution, thereby preventing the clamping surface from being coated, ensuring that the conductive clips can be opened and closed smoothly, and preventing the conductive base film from being punctured by the coating on the clamping surface.

[0020] In a possible implementation of the second aspect, the upper surfaces of the ends of the waist-shaped guide rails near the disconnection part are all inclined planes. Thus, when the conductive clamp moves to the end of the guide rail near the disconnection part, the movable clamping arm can be gradually lifted or lowered, enabling the guide rail to smoothly guide the conductive clamp to gradually open or gradually close, thereby avoiding a large change in the clamping force of the conductive clamp in a short time and preventing the conductive base film from being deformed or damaged accordingly.

Detailed implementation mode

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0039] Electroplating is a process of plating a layer of other metals or alloys on the surface of certain workpieces by using the electrolysis principle. Specifically, a coating metal or other insoluble material is used as the anode, the workpiece to be plated is used as the cathode, and a liquid containing coating metal ions is used as the plating solution. For example, in the electroplating process of a conductive base film, the conductive base film serves as the cathode. Before electroplating, an electric current is applied to the anode and the cathode, and a circuit is formed among the anode, the plating solution, and the cathode. During the electroplating process, the cations of the coating metal are reduced on the surface of the workpiece to be plated to form a coating.

[0040] In the process of manufacturing the current collector of a lithium-ion battery, an electroplating process is usually used to form a relatively thick metal coating on a conductive base film to make the current collector. This electroplating process can be specifically completed by using a coating machine.

[0041] The coating machine includes a plating solution tank and a conductive base film conveying device. The plating solution tank is filled with a plating solution, and the conductive base film conveying device is used to convey the conductive base film into the plating solution tank. Specifically, the conductive base film conveying device includes a conveyor belt and a conductive clamp. The conductive clamp is used to hold the conductive base film and apply an electric current to the conductive base film, and the conveyor belt is used to drive the conductive clamp to move so that the conductive base film enters the plating solution tank.

[0042] The general process of the conductive clamp holding and conveying the conductive base film is as follows: The conductive clamp is in an open state before entering the plating solution tank, and then switches from the open state to the closed state to hold the conductive base film; then the conductive clamp is driven by the conveyor belt into the plating solution tank and moves in the plating solution tank, and at this time the conductive clamp is always in the holding state; when the conductive clamp holds the conductive base film and leaves the plating solution tank, the conductive clamp switches from the holding state to the open state to release the holding of the conductive base film. Therefore, the conductive clamp needs to frequently switch between the open state and the closed state during this process. If it is manually controlled, the operation is inconvenient, and the opening position and the closing position cannot be accurately controlled, and the labor cost will also increase.

[0043] In view of this, the embodiments of the present invention provide a conductive clip transfer opening and closing device and a coating machine, which can automatically clamp or release the conductive clip at a preset position, with convenient operation and labor cost savings.

[0044] The following specifically describes the conductive clip transfer opening and closing device and the coating machine through specific embodiments:

[0045] Embodiment 1

[0046] The embodiment of the present application provides a transfer opening and closing device for a conductive clip, as Figure 1 and Figure 2 shown, including: a conductive clip 1, a transfer device 2 and a guide rail 3. The conductive clip 1 includes a fixed clamping arm 11 and a movable clamping arm 12. The fixed clamping arm 11 is movably connected to the movable clamping arm 12. A guiding portion 13 is provided on the movable clamping arm 12. The movable clamping arm 12 can move relative to the fixed clamping arm 11 in the vertical direction (i.e., the X direction) so that the conductive clip 1 is in a clamped state or an open state; the transfer device 2 is used to drive the conductive clip 1 to move along a preset trajectory; the guide rail 3 is arranged along the moving path of the conductive clip 1. When the guiding portion 13 cooperates with the guide rail 3, the movable clamping arm 12 will be lifted by the guide rail 3 to open the conductive clip 1. When the guiding portion 13 is disengaged from the guide rail 3, the movable clamping arm 12 falls under the action of gravity to close the conductive clip 1.

[0047] In the above embodiment, the fixed clamping arm 11 is movably connected to the movable clamping arm 12, and the movable clamping arm 12 can move relative to the fixed clamping arm 11 in the X direction. Therefore, under the action of gravity, the movable clamping arm 12 can move downward relative to the fixed clamping arm 11, so that the conductive clip 1 can be in a closed state. In addition, the transfer device 2 can drive the conductive clip 1 to move along a preset trajectory, and the guide rail 3 is arranged along the moving path of the conductive clip 1. Thus, when the conductive clip 1 moves along the preset trajectory and the guiding portion 13 provided on the movable clamping arm 12 cooperates with the guide rail 3, the guiding portion 13 will drive the movable clamping arm 12 to lift, so that the movable clamping arm 12 moves upward relative to the fixed clamping arm 11, thereby opening the conductive clip 1. When the conductive clip 1 continues to move along the preset trajectory and the guiding portion 13 is disengaged from the guide rail 3, the movable clamping arm 12 can move downward under the action of gravity, so that the conductive clip 1 is closed again. Thus, in actual use, only by arranging the guide rail 3 at a preset position on the moving path of the conductive clip 1, the opening position and closing position of the conductive clip 1 can be accurately controlled, that is, the guide rail 3 is arranged at the position where the conductive clip 1 needs to be opened, and the guide rail 3 is not arranged at the position where the conductive clip 1 needs to be closed.

[0048] Specifically, as Figure 3As shown in the figure, the fixed clamping arm 11 includes a fixed rod 111 arranged in the vertical direction and a first clamping part 112 arranged at the lower end of the fixed rod 111 and extending in the horizontal direction. The movable clamping arm 12 includes a movable rod 121 arranged in the vertical direction and a second clamping part 122 arranged at the lower end of the movable rod 121 and extending in the horizontal direction. The fixed rod 111 is fixedly connected to the conveying device 2, enabling the conveying device 2 to drive the conductive clip 1 to move. The movable rod 121 is movably connected to the fixed rod 111, and the second clamping part 122 is located above the first clamping part 112. The guiding part 13 is arranged on the movable rod 121. Thus, when the guiding part 13 cooperates with the guide rail 3, the guiding part 13 can drive the movable rod 121 to be lifted by the guide rail 3, so that the second clamping part 122 is separated from the first clamping part 112, and the conductive clip 1 is opened; when the guiding part 13 is separated from the guide rail 3, under the action of gravity, the movable rod 121 and the second clamping part 122 fall, so that the second clamping part 122 fits with the first clamping part 112, and the conductive clip 1 is closed. Moreover, the first clamping part 112 and the second clamping part 122 extend in the horizontal direction, so that the clamping direction of the conductive clip 1 is in the horizontal direction to clamp the horizontally placed conductive base film.

[0049] The above-mentioned guiding part 13 can have various structural forms. For example, Figure 4 As shown in the figure, a guide wheel 131 can be used as the guiding part 13, and the guide wheel 131 is fixed on the movable rod 121. Therefore, when the guide wheel 131 slides on the guide rail 3, the movable rod 121 will be lifted, so that the conductive clip 1 is opened. When the guide wheel 131 is separated from the guide rail 3, the movable rod 121 will fall under the action of gravity, so that the conductive clip 1 is closed. Also, since there is a sliding contact between the guide wheel 131 and the guide rail 3, a sliding friction will be formed, and the frictional resistance is relatively large. Therefore, the guide wheel 131 can be set in a rotatable form. Specifically, the guide wheel 131 can include a cylindrical guide wheel 131 body and a fixed shaft connected to the guide wheel 131 body. One end of the fixed shaft is embedded at the position of the central axis of the guide wheel 131 body and can rotate within the guide wheel 131 body, and the other end is fixed to the upper end of the movable rod 121. Thus, the guide wheel 131 body can rotate around the fixed shaft. Thus, when the guide wheel 131 cooperates with the guide rail 3, the rotatable guide wheel 131 can change the sliding contact into a rolling contact, reduce the frictional resistance, and thus reduce the wear of the guide wheel 131 and the guide rail 3.

[0050] For example, Figure 5 and Figure 6As shown, the guiding portion 13 can also be configured to include a slider 132 and balls 133 connected to the bottom of the slider 132. The slider 132 can be in a cuboid structure. One side of the slider 132 is fixed to the movable rod 121. A groove is provided at the bottom of the slider 132, and several balls 133 are embedded in the groove. A small part of the balls 133 protrudes from the groove, and the balls 133 can rotate within the groove. Thus, the slider 132 can be in rolling cooperation with the guide rail 3 through the rotatable balls 133 at the bottom. Therefore, when the slider 132 moves on the guide rail 3, while being able to drive the movable rod 121 to lift and open the conductive clip 1, it also has a relatively small rolling friction resistance, which can effectively reduce the wear of the guide rail 3 and the slider 132.

[0051] As Figure 3 shown, for a conductive clip 1, the movable rod 121 and the fixed rod 111 can be movably connected through a rocker assembly. The rocker assembly includes a first rocker 14 and a second rocker 15 that are parallel to each other. One end of the first rocker 14 is hinged to the fixed rod 111, and the other end is hinged to the movable rod 121. Correspondingly, one end of the second rocker 15 is hinged to the fixed rod 111, and the other end is hinged to the movable rod 121. Thus, the fixed rod 111, the movable rod 121, the first rocker 14, and the second rocker 15 form a parallelogram planar link mechanism, enabling the movable rod 121 to swing reciprocally relative to the fixed rod 111, thereby making the conductive clip 1 in a clamping state or an open state. And the parallelogram planar link mechanism is the simplest planar link mechanism with mature manufacturing processes, simple structures, and easy to fabricate and implement.

[0052] The above-mentioned conductive clip 1 can cooperate with the guide rail 3 to enable the conductive clip 1 to be closed or loosened. Then, as Figure 7As shown in the figure, the upper surface of the guide rail 3 can be set as the guiding surface 31, and the guiding surface 31 is designed to include a rising inclined surface 311 and a falling inclined surface 313 arranged in sequence along the moving track of the conductive clip 1, so that the guiding part 13 can gradually rise or gradually fall, so that the movable rod 121 can be gradually lifted or gradually lowered. That is, when the guiding part 13 moves on the rising inclined surface 311, the guiding part 13 drives the movable rod 121 to be gradually lifted, so that the second clamping part 122 and the first clamping part 112 are gradually separated, so that the conductive clip 1 is gradually opened. When the guiding part 13 moves on the falling inclined surface 313, the movable rod 121 gradually descends under the action of gravity, so that the second clamping part 122 and the first clamping part 112 are gradually close to each other, so that the conductive clip 1 is gradually closed. Therefore, the inclined surface can smoothly guide the guiding part 13 to be gradually lifted or lowered, so that the movable rod 121 can slowly rise or move down, so that the conductive clip 1 can gradually loosen the clamping of the conductive base film or gently clamp the conductive base film, avoiding a sharp change in the clamping force of the conductive clip 1 on the conductive base film, reducing the contact tension, and thus preventing the conductive base film from being deformed. And it avoids a large impact force caused by the rapid descent of the movable rod 121, thus preventing damage to the conductive base film.

[0053] As Figure 7 shown, the guiding surface 31 is also provided with a horizontal guiding surface 312 connected between the rising inclined surface 311 and the falling inclined surface 313. Thus, when the guiding wheel 131 moves to the rising inclined surface 311 and drives the movable rod 121 on the conductive clip 1 to be lifted to a predetermined height and the conductive clip 1 is opened, the guiding wheel 131 will smoothly move to the horizontal guiding surface 312, and the lifting height of the movable rod 121 can be kept unchanged, so that the conductive clip 1 is stably maintained in the open state until the guiding wheel 131 moves to the preset position to be closed, that is, the falling inclined surface 313, and the conductive clip 1 is closed again. Therefore, after the conductive clip 1 completes the clamping movement of the conductive base film for the previous time and loosens it, during the preparation for the next clamping process, the conductive clip 1 is always in the open state. Therefore, when the conductive clip 1 moves to the falling inclined surface 313, it can be directly switched from the open state to the closed state, which can effectively save time.

[0054] Embodiment 2

[0055] The embodiment of the present application also provides a coating machine, including a plating solution tank 100 and the conductive clip transmission opening and closing device 200 of Embodiment 1.

[0056] For the coating machine provided in this embodiment, since the conductive clip transmission opening and closing device 200 of Embodiment 1 is adopted, during the coating process, when the conductive clip 1 moves along the preset track, the switching between the automatic clamping or loosening state of the conductive clip 1 can be realized, and the structure is simple and practical, improving the coating efficiency of the coating machine.

[0057] Specifically, as Figure 8 shown, the conductive clip transfer opening and closing device 200 includes: a first conveyor belt 201 and a second conveyor belt 202, a first conductive clip 203 and a second conductive clip 204, and a first guide rail 205 and a second guide rail 206. The first conveyor belt 201 and the second conveyor belt 202 are respectively arranged on both sides of the plating solution tank 100 and both extend along the first direction (i.e., the Y direction); there are multiple first conductive clips 203, and the multiple first conductive clips 203 are arranged on the first conveyor belt 201 along the Y direction. Correspondingly, multiple second conductive clips 204 are arranged on the second conveyor belt 202 along the Y direction. The first conductive clip 203 and the second conductive clip 204 are respectively used to clamp the opposite side edges of the horizontally placed conductive base film to drive the conductive base film to horizontally enter and exit the plating solution tank 100 along the Y direction; the first guide rail 205 and the second guide rail 206 are symmetrically arranged on both sides of the plating solution tank 100 along the midline in the width direction of the plating solution tank 100. The first guide rail 205 is used to cooperate with the first conductive clip 203 to guide the opening or closing of the first conductive clip 203, and the second guide rail 206 is used to cooperate with the second conductive clip 204 to guide the opening or closing of the second conductive clip 204.

[0058] Thus, during the electroplating operation, multiple conductive clips 1 are driven by the conveyor belt to move along the Y direction. When the conductive base film needs to enter the plating solution tank 100 for coating, the conveyor belt drives the conductive clip 1 to move to a preset position, so that the conductive clip 1 can cooperate with the guide rail 3 to close the conductive clip 1, clamp the conductive base film from both sides and drive the conductive base film to move along the Y direction, and at the same time energize the conductive base film for electroplating; when the conductive base film finishes coating and leaves the plating solution tank 100 and moves to a preset position, the guide rail 3 cooperates with the conductive clip 1 again to open the conductive clip 1 and release the clamping of the conductive base film.

[0059] It should be noted that this coating machine has a horizontal film running mode. During coating, the conductive base film clamped by the first conductive clip 203 and the second conductive clip 204 is entirely inside the plating solution tank 100, thereby avoiding the phenomenon of electric breakdown caused by the decrease in cooling effect when a part of the conductive base film is outside the plating solution tank 100.

[0060] In this embodiment, the guide rail 3 cooperates with the conductive clip 1 so that the conductive clip 1 can clamp the conductive base film and enter the plating solution tank 100 and move in the plating solution tank 100, and can release the clamping of the conductive clip 1 after the conductive base film finishes coating. Specifically, as Figure 9As shown, the first guide rail 205 can be set to include a first guiding section 2051 and a second guiding section 2052. The first guiding section 2051 corresponds to the inlet side of the plating solution tank 100, and a descending slope 313 is provided on the first guiding section 2051 to close the conductive clip 1. The second guiding section 2052 corresponds to the outlet side of the plating solution tank 100, and an ascending slope 311 is provided on the second guiding section 2052 to open the conductive clip 1. Specifically, when the first conductive clip 203 slides along the first guiding section 2051, the descending slope 313 on the first guiding section 2051 can cause the movable rod 121 of the first conductive clip 203 to drop, so as to guide the first conductive clip 203 to close, enabling the first conductive clip 203 to clamp the conductive base film and move it; when the first conductive clip 203 slides between the first guiding section 2051 and the second guiding section 2052, the first conductive clip 203 is in a closed state under the action of gravity; when the first conductive clip 203 slides along the second guiding section 2052, the ascending slope 311 on the second guiding section 2052 can cause the movable rod 121 of the first conductive clip 203 to be lifted, so as to guide the first conductive clip 203 to open and release the clamping of the conductive base film. Thus, the first guide rail 205 can guide the first conductive clip 203 to switch between the automatic closing and releasing states when moving to a preset position. Similarly, the second guide rail 206 can be set to the same structure to guide the second conductive clip 204 to switch between the automatic closing and releasing states, which will not be elaborated here.

[0061] As Figure 9 shown, the first conveyor belt 201 can adopt an oval conveyor belt, and the first guide rail 205 can adopt an unclosed oval guide rail. The oval guide rail is arranged around the oval conveyor belt, and the oval guide rail has a disconnection part, and the disconnection part corresponds to the position of the plating solution tank 100.

[0062] Specifically, as Figure 10 shown, the oval first conveyor belt 201 can be set to include a first horizontal section conveyor belt 2011, a second horizontal section conveyor belt 2012, a first arc section conveyor belt 2013, and a second arc section conveyor belt 2014. The first horizontal section conveyor belt 2011 and the second horizontal section conveyor belt 2012 are parallel to each other and extend along the Y direction. One end of the first horizontal section conveyor belt 2011 and the second horizontal section conveyor belt 2012 is connected by the first arc section conveyor belt 2013, and the other end is connected by the second arc section conveyor belt 2014, and the first horizontal section conveyor belt 2011 is arranged close to the plating solution tank 100. Similarly, the second conveyor belt 202 can also be set to an oval conveyor belt, and the structure is the same as that of the first conveyor belt 201, which will not be elaborated here. Thus, the first conveyor belt 201 can drive a plurality of first conductive clips 203 to rotate in an oval shape, and the second conveyor belt 202 can drive a plurality of second conductive clips 204 to rotate in an oval shape, so that the conductive clip 1 can be continuously recycled.

[0063] As Figure 10 shown, the first guide rail 205 can be arranged to include a first arc guide rail section 2053, a first linear guide rail section 2054, and a second arc guide rail section 2055 that are sequentially arranged around the first conveyor belt 201. The first arc guide rail section 2053 corresponds to the first arc section conveyor belt 2013 and has a rising inclined surface 311 on the upper surface of the end close to the disconnection part. The first linear guide rail section 2054 corresponds to the second horizontal section conveyor belt 2012, and a horizontal guiding surface 312 is provided on the upper surface of the first linear guide rail section 2054. The second arc guide rail section 2055 corresponds to the second arc section conveyor belt 2014, and a descending inclined surface 313 is provided on the upper surface of the end close to the disconnection part. Correspondingly, the second guide rail 206 can also adopt the same structural form to cooperate with the second conductive clip 204, which will not be elaborated here. Thus, the conveyor belt drives the conductive clip 1 to cooperate with the first arc guide rail section 2053, the first linear guide rail section 2054, and the second arc guide rail section 2055 in sequence. When cooperating with the first arc guide rail section 2053, the conductive clip 1 is gradually opened. When cooperating with the first linear guide rail section 2054, the conductive clip 1 is maintained in the open state. When cooperating with the second arc guide rail section 2055, the conductive clip 1 can be gradually closed. When the conveyor belt drives the conductive clip 1 to be at the position of the disconnection part of the guide rail, the conductive clip 1 is in the closed state.

[0064] Specifically, the length of the disconnection part of the guide rail in the Y direction is greater than the length of the plating solution tank 100, that is, both the first arc guide rail section 2053 and the second arc guide rail section 2055 are located outside the plating solution tank 100. The first arc guide rail section 2053 is located outside the out-tank side of the plating solution tank 100, and the second arc guide rail section 2055 is located outside the in-tank side of the plating solution tank 100. Thus, the conductive clip 1 can be in the clamped state before entering the plating solution and can release the clamping of the conductive base film and be in the open state only after leaving the plating solution, so as to avoid the contact between the clamping surface of the conductive clip 1 and the plating solution, prevent the clamping surface from being coated with a film, ensure that the conductive clip 1 can be smoothly opened and closed, and prevent the conductive base film from being punctured by the coating on the clamping surface.
