Technical Field
[0001] The present invention relates to the technical field of electroplating equipment, and particularly relates to a flattening roller, a conveying mechanism and a processing device. Background Art
[0002] In the conventional coil electroplating process, vertical electroplating is generally adopted.

The upper fixture is driven by a moving mechanism to move horizontally, and the lower fixture is driven passively by the plate to slide in the track on the base frame. During the movement of the upper fixture, the plate is driven to pass through the treatment tanks of different required processes in sequence. Since the plate moves, the upper fixture drives the top of the plate to move, and the bottom of the plate drives the lower fixture to move in the track, so that the bottom of the plate lags behind the top of the plate during the movement, which easily causes the surface of the plate to form wrinkles when moving in the solution of the treatment tanks of different processes, affecting the electroplating process and electroplating quality of the plate.

[0038] The technical solution of the present invention has the following advantages:
[0039] 1. A flattening roller provided by the present invention, along the circumferential direction of the flattening roller, in at least part of the flattening roller, the radial distance from the rotation axis of the flattening roller to its outer surface gradually decreases from the middle section of the flattening roller towards its two ends along the extension direction of the rotation axis, and the outer circumferential surface of the flattening roller is a curved surface. That is, the maximum circumference of the middle section of the flattening roller moving in a circular motion around the rotation axis is greater than the maximum circumference of the two ends of the flattening roller moving in a circular motion around the rotation axis. When the sheet moves horizontally and is locally relaxed, wrinkles are likely to occur. The relaxed sheet passes through the flattening roller. During the rotation of the flattening roller, it presses against the sheet in the direction perpendicular to the sliding path of the sheet, providing a wrapping surface for the sheet that is larger than that of a cylindrical driving roller, realizing the tensioning and flattening of the sheet.
[0040] 2. The present invention provides a flattening roller. Any cross-section shape of the flattening roller perpendicular to the rotation axis is circular, so that the flattening roller always acts on the surface of the sheet during rotation, ensuring continuous tensioning and flattening.
[0041] 3. The present invention provides a conveying mechanism, including a driving component for driving the sheet to slide from the first end of the base frame to the second end. The flattening roller is rotatably arranged on the sliding path of the sheet, and the rotation axis of the flattening roller is perpendicular to the sliding direction of the sheet. In actual production applications, the sheet is released from one end and wound at the other end. The release end is often sleeved on the passive shaft, and the winding end is the active shaft. During the process of the active shaft pulling and winding the sheet, the rotation speed of the passive shaft is sometimes greater than that of the active shaft, resulting in the relaxation of the sheet between the two ends. By arranging the flattening roller between the two ends, the sheet passing around the flattening roller can avoid wrinkles caused by relaxation of the sheet and improve the winding quality.
[0042] 4. The present invention provides a processing device. At least one set of driving rollers and flattening rollers are simultaneously arranged in the processing tank. The driving rollers and the flattening rollers are arranged axially parallel. Any set of driving rollers includes a driving roller and a driven roller. A sheet passing gap is formed between the driving roller and the driven roller. The sheet passes through the sheet passing gap and winds around the flattening roller. The driving roller and the driven roller clamp and drive the sheet to move from both sides, and through the joint pulling and flattening of the flattening roller and the driving roller, the flatness of the sheet during the sliding process is ensured.
[0043] 5. The present invention provides a processing device. The processing tank is an electroplating tank, and the over-board gap is horizontally arranged. At least one set of baskets for holding anode materials is arranged in the electroplating tank. Any set of baskets for holding anode materials includes an upper basket and a lower basket, and the upper basket and the lower basket are distributed on the upper and lower sides of the sliding path of the plate. The lower basket includes a basket body, a guiding frame, a conveying port and a conveying component. Mesh holes are arranged on the wall surface of the basket body. The guiding frame is arranged in the inner cavity of the basket body, dividing the inner cavity of the basket body into two upper and lower accommodating cavities arranged side by side. A conveying port is opened on the side wall of the basket body located in the upper accommodating cavity. The conveying component is arranged outside the tank body and connected to the conveying port. The guiding frame is arranged obliquely downward from the conveying port towards the other end of the basket body opposite to the conveying port. The top surface of the guiding frame forms a supporting position for placing anode materials. There is at least one communication hole on the guiding frame that communicates the upper and lower accommodating cavities of the basket body. The lower accommodating cavity is used to receive the anode materials that fall through the communication hole. During the process of loading the anode materials into the inner cavity of the basket body by the conveying component, the anode materials slide into the other end of the upper accommodating cavity of the basket body under the guidance of the inclined guiding frame. The anode materials are gradually dissolved and consumed in the solution, resulting in a decrease in size, and then fall into the lower accommodating cavity through the communication hole. At this time, anode materials can be continuously added to the upper accommodating cavity; or, when initially adding anode materials, the anode materials are guided by the guiding frame to the end far from the conveying port and directly fall into the lower accommodating cavity through the communication hole at this place. After a certain amount of anode materials in the lower accommodating cavity, the communication hole at this place is blocked, so that the subsequent anode materials put through the conveying port are sequentially stacked and stay on the supporting position of the guiding frame. The conveying component is arranged outside the basket, and the anode materials entering the inner cavity of the basket can be distributed in the basket body under the guidance of the guiding frame, without causing the accumulation of anode materials at the conveying port, and does not affect the addition of anode materials during the electroplating process. The feeding method is simple and efficient.
[0044] 6. The present invention provides a processing device. There are at least five processing tanks, and among them, five processing tanks are, in sequence along the sliding direction of the plate, an electroplating tank, a first water washing tank, an antioxidant tank, a second water washing tank and a blowing and drying tank. The processing tanks are arranged in sequence to form a horizontal electroplating line. At least one set of driving rollers and flattening rollers is arranged in any processing tank to ensure that the plate surface remains flat when the plate slides through each processing process in each processing tank, which is convenient for winding the plate without affecting the electroplating quality.

[0078] Embodiment 1
[0079] This embodiment provides a flattening roller. As Figure 3 shown, the flattening roller 1 includes a roller barrel base 11 and a rotating shaft 12. The rotating shaft 12 is coaxially arranged with the roller barrel base 11 and penetrates through both ends of the roller barrel base 11. Along the circumferential direction of the flattening roller 1, in at least part of the flattening roller 1, the radial distance from the rotation axis 121 of the flattening roller 1 to its outer surface gradually decreases from the middle section of the flattening roller 1 towards its two ends along the extension direction of the rotation axis 121, and the outer peripheral surface of the flattening roller 1 is a curved surface. That is, the maximum circumference of the middle section of the flattening roller 1 rotating around the rotation axis 121 is greater than the maximum circumference of the two ends of the flattening roller 1 rotating around the rotation axis 121. During the rotation of the flattening roller 1, it presses against the plate in the direction perpendicular to the sliding path of the plate, and when the surface of the roller barrel base 11 at the position with the maximum circumference contacts the plate, it can provide a wrapping surface for the plate that is larger than that of a cylindrical driving roller, realizing the tensioning and flattening of the plate.
[0080] Furthermore, any cross-sectional shape of the flattening roller 1 perpendicular to the rotation axis 121 is an axisymmetric figure. As Figure 4 shown, the cross-sectional shape of the flattening roller 1 is circular. As Figure 5As shown, the cross-sectional shape of the flattening roller 1 is elliptical. Of course, it can also be other shapes. In this embodiment, any cross-sectional shape of the flattening roller 1 perpendicular to the rotation axis 121 is circular. The diameter of the radial cross-section of the middle section of the flattening roller 1 gradually decreases towards both ends of the flattening roller 1. The outer surface of its roller body 11 is a smoothly transitioning curved surface. The circular cross-section enables the flattening roller 1 to always act on the surface of the sheet during rotation, ensuring continuous tensioning and flattening of the sheet.
[0081] As the first alternative embodiment of Embodiment 1, the flattening roller 1 can be integrally formed.
[0082] Embodiment 2
[0083] This embodiment provides a conveying mechanism, including a driving component and at least one flattening roller 1 in Embodiment 1. The driving component is used to drive the sheet to slide from the first end of the base frame 10 to the second end. The driving component includes a driving shaft 21 and a driven shaft 31. As Figure 1 shown, the driven shaft 31 is rotatably arranged at the first end, and the driving shaft 21 is rotatably arranged at the second end. The driven shaft 31 is sleeved with a coiled sheet, and the driving shaft 21 is wound around the extraction end of the coiled sheet from the driven shaft 31, that is, unwinding on the driven shaft 31 and winding on the driving shaft 21. The flattening roller 1 is rotatably arranged on the sliding path of the sheet between the first end and the second end. The rotation axis 121 of the flattening roller 1 is arranged perpendicular to the sheet sliding direction. In this embodiment, at least two flattening rollers 1 are provided, and adjacent flattening rollers 1 are arranged at intervals, and the sheet is wound around adjacent two flattening rollers 1 in a similar S-shaped winding manner.
[0084] In actual production applications, the sheet is released from one end and wound at the other end. The release end is sleeved on the driven shaft 31, and the winding end is the driving shaft 21. During the process of the driving shaft 21 pulling and winding the sheet, there is often a situation where the rotation speed of the driven shaft 31 is sometimes greater than that of the driving shaft 21, resulting in the sheet between the first end and the second end being slack. By arranging the flattening roller 1 between the two ends, the sheet passing through the flattening roller 1 can avoid wrinkles caused by slack, improving the winding quality.
[0085] Embodiment 3
[0086] This embodiment provides a processing device, including at least one processing tank and the conveying mechanism in Embodiment 2. The processing tank is arranged on the sliding path of the sheet. An over-sheet gap 101 is formed on the tank wall of the processing tank located on the sliding path of the sheet. In the conveying mechanism, the driving shaft 21 and the driven shaft 31 in the driving assembly are rotatably arranged at both ends of the processing tank along the sliding path of the sheet respectively. The flattening roller 1 in the conveying mechanism is rotatably arranged on the tank wall of the processing tank through a rotating shaft 12. At least one set of driving rollers 4 is arranged in any one of the processing tanks. The driving rollers 4 are arranged axially parallel to the flattening roller 1. Both ends of the driving rollers 4 are rotatably arranged on the side wall of the processing tank. Any one set of driving rollers 4 includes a driving roller 41 and a driven roller 42 arranged oppositely. An over-sheet gap 101 is formed between the driving roller 41 and the driven roller 42.
[0087] In this embodiment, the over-sheet gap 101 is arranged horizontally. The driving rollers 4 and the flattening roller 1 are both arranged horizontally and rotatably in the processing tank. The conveying mechanism drives the sheet to move horizontally through the over-sheet gap 101.
[0088] In this embodiment, there are at least five processing tanks. Among them, the five processing tanks are, in sequence along the sliding direction of the sheet, an electroplating tank A, a first water washing tank B1, an antioxidant tank C, a second water washing tank B2, and a blowing and drying tank D. All the processing tanks are arranged side by side to form a horizontal electroplating line. As Figure 1 Or Figure 2 shown, there are five electroplating tanks A. The five electroplating tanks A are arranged side by side along the sliding path of the sheet. The horizontal electroplating line is sequentially provided with a roll-type sheet feeding machine 3, an inlet detection device E1, five electroplating tanks A arranged side by side, a first water washing tank B1, an antioxidant tank C, a second water washing tank B2, a blowing and drying tank D, an outlet detection device E2, and a roll-type sheet collecting machine 2 from right to left. The inlet detection device E1 and the outlet detection device E2 are conventional electroplated sheet detection devices.
[0089] As Figure 6 shown, the electroplating tank A is erected on a base frame 10. The electroplating tank A includes a copper tank A1 and a conductive tank A2 arranged horizontally in sequence. A partition 100 is arranged between the copper tank A1 and the conductive tank A2. A horizontal over-sheet gap 101 is formed on the partition 100 corresponding to the sliding path of the sheet. Two flattening rollers 1 are arranged staggeredly in the conductive tank A2, and the rotating shaft 12 of the flattening roller 1 penetrates through the tank wall and extends out of the tank wall. In this embodiment, the flattening roller 1 can be connected to an external power source through a brush or a wire for energizing the sheet to be electroplated. A set of driving rollers 4 is respectively arranged at both sides of the partition 100 in the conductive tank A2. The driving rollers 4 are adapted to block the over-sheet gap 101 on the partition 100 to a certain extent, and the over-sheet gap 101 between the driving roller 41 and the driven roller 42 in the driving rollers 4 is located in the same plane as and is directly opposite to the over-sheet gap 101 of the partition 100. As Figure 8As shown in the figure, a spraying assembly is arranged in the conductive groove A2. The spraying assembly includes a first spraying pipe 60 arranged corresponding to the flattening roller 1 one by one. The conductive liquid (the composition is similar to the electroplating solution, so the solution overflow and mixing will not affect the electroplating effect) is continuously sprayed onto the flattening roller 1 through the first spraying pipe 60 to lubricate and clean the surface of the flattening roller 1.
[0090] As Figure 7 shown, in this embodiment, the electroplating solution is contained in the copper groove A1. A first bottom plate 70 is arranged at the bottom of the copper groove A1. The cross-section of the first bottom plate 70 is in a V-shaped structure with a larger opening. A basket for containing the anode material is arranged at the middle position of the copper groove A1. The basket is made of titanium material. Two sets of driving rollers 4 are respectively arranged on both sides of the basket and close to the two side partitions 100. A flow guide plate 71 is arranged between two adjacent sets of driving rollers 4. The flow guide plate 71 is fixed on the first bottom plate 70, and the bottom of the flow guide plate 71 is in a V-shaped structure matching the first bottom plate 70. A flow guide opening 72 is opened at the tip of the V-shaped structure of the flow guide plate 71. A plurality of liquid discharge holes 73 are distributed on the flow guide plate 71 above the flow guide opening 72. The settings of the liquid discharge holes 73, the flow guide opening 72 and the V-shaped structure facilitate the overflow liquid in the tank to quickly flow back into the solution circulation system. A second bottom plate 74 is horizontally arranged between two flow guide plates 71 in the same copper groove A1. The second bottom plate 74 is located above the liquid discharge holes 73. The basket for containing the anode material is arranged on the second bottom plate 74. In this embodiment, a group of baskets for containing the anode material is arranged in each copper groove A1. Any group of baskets for containing the anode material includes an upper basket a5 and a lower basket. The upper basket a5 and the lower basket are distributed on the upper and lower sides of the sliding path of the plate. As Figure 9 shown, the upper basket a5 has a cavity for containing the anode material. The upper basket a5 is located above the plate, and the upper basket a5 is open at the top, which is convenient for the input of the anode material. In this embodiment, one upper basket a5 corresponds to two lower baskets, and the two lower baskets are arranged in parallel below the upper basket a5.
[0091] As Figure 10 shown, the lower basket includes a basket body a1, a guiding frame and a conveying component. In this embodiment, the basket body a1 is integrally in a cuboid structure. At least one mesh hole (not shown in the figure) is arranged on the wall surface of the basket body a1, which can supply the solution in the electroplating tank to enter the inner cavity of the basket to dissolve the anode material. The mesh hole is also beneficial to the discharge of the anode mud remaining after the dissolution of the anode material. In this embodiment, the side walls and the top surface of the basket body a1 are all covered with mesh holes, and an anode mud filter bag (not shown in the figure) is covered outside all the mesh holes to filter and temporarily store the anode mud through the filter bag to avoid the anode mud being doped in the solution and affecting the electroplating.
[0092] As Figure 10 shown, fixing plate ribs a13 are evenly distributed on the inner walls of the two opposite sides of the basket body a1. The guiding frame is fixed on the two side fixing plate ribs a13. The fixing plate ribs a13 are beneficial to improving the overall stability of the titanium basket structure. AsFigure 13 As shown, the guiding frame divides the inner cavity of the basket body a1 into upper and lower accommodating cavities arranged side by side. A conveying port a11 is formed on the side wall of the basket body a1 in the upper accommodating cavity. The conveying component is arranged outside the groove body and is hermetically connected to the conveying port a11. In this embodiment, the conveying component is a conveying pipe a3, and the inlet of the conveying pipe a3 is arranged higher than the basket body a1. Since the basket body a1 is below the solution liquid level during the electroplating process, arranging the inlet higher than the basket body a1 can prevent the solution from overflowing when an anode material is put in during the electroplating process.
[0093] As Figure 11 shown, the guiding frame is arranged to slope downward from the conveying port a11 towards the other end of the basket body a1 opposite to the conveying port a11. The top surface of the guiding frame forms a supporting position for placing the anode material. There is at least one communication hole on the guiding frame that communicates the upper and lower accommodating cavities of the basket body a1. The lower accommodating cavity is used to receive the anode material that falls through the communication hole. In this embodiment, as Figure 12 shown, the guiding frame is two guiding strips a2, and the two guiding strips a2 are respectively fixed on two opposite side walls of the basket body a1. A communication hole that communicates the upper and lower accommodating cavities of the basket body a1 is formed between the two guiding strips a2.
[0094] In this embodiment, the distance between the two guiding strips a2 is equal and less than the straight-line distance between the two farthest points on the surface of the anode material. The anode material loaded from the conveying pipe a3 slides or rolls from the conveying port a11 to the other end of the upper accommodating cavity under the guidance of the inclined guiding strips a2. In this embodiment, the anode material is copper balls, and the straight-line distance between the two farthest points on the surface of the copper balls is the diameter of the copper balls. Since the diameter of the copper balls is greater than the distance between the two guiding strips a2, when the copper balls are initially added, the copper balls are arranged in sequence on the supporting position formed by the two guiding strips a2 and are located in the upper accommodating cavity. As the copper balls are dissolved and consumed, the diameter of the copper balls gradually decreases. When the diameter of the copper balls is less than the distance between the two guiding strips a2, the copper balls fall into the lower accommodating cavity. At this time, copper balls can be continuously added from the conveying pipe a3. The newly added copper balls are arranged in sequence on the supporting position formed by the two guiding strips a2 and are located in the upper accommodating cavity. The copper balls in the upper accommodating cavity and the copper balls in the lower accommodating cavity are dissolved and consumed simultaneously. The layer-by-layer consumption and addition of copper balls are beneficial to controlling the dosage of copper balls. At the same time, the more copper balls are added in excess, the more copper balls are dissolved, the more anode mud is generated, the worse the effect of filtering the anode mud by the filter bag, and the more anode mud is mixed in the solution, the more likely it is to affect the electroplating quality.
[0095] When the distance between two guiding bars a2 gradually increases from one end of the conveying port a11 of the basket body a1 towards the other end and the maximum distance is less than the straight-line distance between the two farthest points on the surface of the anode material, that is, the maximum distance is less than the diameter of the copper ball. In the normal state, under the action of gravity, an object always moves from a high point to a low point, that is, the center of gravity moves downward. When the copper ball is placed on the two guiding bars a2, the center of gravity of the copper ball is above the central axis of the track plane formed by the two guiding bars a2. Due to the action of gravity, the center of gravity of the copper ball will move downward. Since the distance between the two guiding bars a2 gradually increases, that is, the distance of the two guiding bars a2 deviating from the track central axis gradually increases, the distance between the center of gravity of the copper ball and the track plane gradually decreases. When the copper ball reaches the other end of the basket body a1, it abuts against the inner wall of the basket body a1 and stops moving. At this time, the center of gravity of the copper ball is closest to the track plane. Since the guiding bars a2 are inclined in the basket cavity, the copper ball has a tendency to roll downward only along the inclined surface. The gradually increasing distance between the two guiding bars a2 is conducive to accelerating the rolling of the copper ball. Especially in the solution, it is more convenient to overcome the resistance of the liquid to achieve the purpose of quickly adding copper balls.
[0096] When there are at least two communication holes on the guiding frame, all the communication holes are sequentially and spacedly distributed on the guiding frame along the inclined direction of the guiding frame. That is, when the distance between two guiding bars a2 gradually increases from one end of the conveying port a11 of the basket body a1 towards the other end and the maximum distance is greater than or equal to the straight-line distance between the two farthest points on the surface of the anode material, that is, the maximum distance is greater than or equal to the diameter of the copper ball. At this time, there are two communication holes formed between the two guiding bars a2. That is, from the starting end, the communication hole formed between the two guiding bars a2 with a distance less than the diameter of the copper ball is the first communication hole, and the communication hole formed between the two guiding bars a2 with a distance greater than or equal to the diameter of the copper ball is the second communication hole. The first communication hole and the second communication hole are sequentially distributed on the rolling path of the copper ball along the inclined direction of the guiding bar a2. After the copper ball is put in from the conveying port a11, it rolls along the guiding bar a2 to the second communication hole and rolls down from the second communication hole into the lower accommodating cavity. The copper balls are distributed on the bottom surface of the lower accommodating cavity. In this embodiment, the bottom surface of the basket body a1 is a horizontal plane. When the number of copper balls in the lower accommodating cavity reaches a certain amount, the copper balls located below the second communication hole gradually accumulate and block the second communication hole, so that the subsequent copper balls put in through the conveying port a11 are sequentially stacked and stay on the supporting positions of the guiding bars a2 in the upper accommodating cavity. Since the copper balls in the lower accommodating cavity only accumulate below the second communication hole and the guiding bars a2 are inclined, there is still a certain accommodating space left in the lower accommodating cavity below the first communication hole. As the copper balls are consumed, the copper balls in the upper accommodating cavity can still fall into this accommodating space.
[0097] Of course, to increase the initial amount of copper balls added, the bottom surface of the lower accommodating cavity can be inclined downward from the end far away from the conveying port a11 towards the end close to the conveying port a11, so that the copper balls enter the lower accommodating cavity through the second communication hole and roll along the inclined surface to quickly fill the lower accommodating cavity.
[0098] As Figure 10 or Figure 11 shown, a dredging port a31 is provided on the conveying pipe a3 avoiding the inlet position, and the dredging port a31 communicates with the upper accommodating cavity. When the anode material is blocked during the movement on the guiding frame, a dredging rod (not shown in the figure) or other rod components can be inserted into the dredging port a31 to push the anode material inward for dredging. A sealing cover is provided on the dredging port a31, and the sealing cover is in threaded fit with the outer edge of the dredging port a31. Under normal conditions, the sealing cover is tightened and sealed on the dredging port a31.
[0099] As Figure 10 shown, a cleaning port a12 is also provided at one end of the lower accommodating cavity, which is convenient for clearing the anode mud deposited on the bottom surface from the cleaning port a12 when cleaning the titanium basket. A sealing plate a4 is detachably covered on the cleaning port a12. In this embodiment, a slot (not shown in the figure) is provided on the inner wall surface of the basket body a1 on one side of the cleaning port a12, and the sealing plate a4 is inserted and fixed in the slot.
