Description

Technical Field

[0001] The invention relates to the technical field of electroplating processing devices, and in particular to a slotted conductive roller used for an electroplating transmission component and a slotting method thereof. Background Art

[0002] As an indispensable component in modern industrial production, electroplating equipment has been widely used in the automotive, electronics, aerospace and other fields. Electroplating transmission components are necessary components for the operation of electroplating equipment, so their quality and performance directly affect the operating efficiency and stability of the entire equipment.

[0003] Ordinary roll-to-roll electroplating transmission components often use the most common smooth rollers. During operation, the film will deviate left and right, resulting in wrinkles, which is easy to cause holes or burn the board when power is turned on, and further affects the uniformity of the board surface; during the film transmission process, traditional electroplating transmission components will bring electrolyte to the conductive roller to form liquid accumulation, resulting in copper on the conductive roller. The copper on the conductive roller will cause inconsistent electroplating current density, reduced electroplating effect, and product film holes. Therefore, there is a huge room for improvement in the production process; and when the electroplating speed is too fast, a water film will be generated between the roller and the film to form a double electrode effect, which will cause part of the current to act between the roller and the product film, which is easy to cause production defects such as copper on the roller and scratches on the product film.

[0033] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clear and explicit, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0035] Embodiment 1:

[0036] like Figure 1 As shown, a slotted conductive roller for electroplating transmission components includes a roller and a shaft head, and the length of the roller is set to 0.5M-5M. Among them, the shaft head includes a first shaft head and a second shaft head, and the first shaft head and the second shaft head are both arranged at both ends of the roller. A first shaft head surface is arranged between the first shaft head and the roller, and a second shaft head surface is arranged between the second shaft head and the roller. The first shaft head surface and the second shaft head surface need to be arranged in parallel. The shaft heads at both ends of the conductive roller can be designed according to the actual situation of the slot body, that is, the first shaft head and the second shaft head adopt a stepped connecting rod with a gradually smaller diameter or a connecting rod with a conical slope or a connecting rod with the same diameter as the roller, so as to better fix the roller and enhance the stability of the equipment during operation. A plurality of conductive roller wheel patterns are arranged on the outer surface of the roller, and the shape of the conductive roller wheel patterns is set to be a herringbone groove. Specifically, the groove width of the herringbone groove is 0.1mm-50mm, and the groove depth is 0.1mm-10mm; the chamfers on both sides of the herringbone groove are R0.01mm-R5mm; the connection angle of the two sides of the groove bodies of any two adjacent groups of herringbone grooves is 10°-160°, and the distance between the two groove bodies is 5mm-200mm; and the herringbone groove also needs to be treated with chamfered glue spraying or chamfered without glue coating. The thickness of the glue coating after chamfered glue spraying is 0.05-6mm, and the width is 0.1mm-30mm.

[0037] When the electroplating transmission component uses several conductive rollers of the present invention, since the conductive rollers are provided with herringbone patterns, during the operation of the equipment, they not only play the role of transmission and conduction, but also use the patterns on the rollers to remove residual copper powder through the grooves, thereby reducing the particulate impurities on the conductive rollers, ensuring the conductive stability of the conductive rollers, and eliminating the possibility of voltage instability and product pressure points caused by poor contact and pressure damage of the conductive rollers due to impurities, thereby reducing the maintenance frequency to a certain extent; in addition, the product film reduces the accumulation of liquid at the angle between the film surface and the roller wheel during the electroplating process, making the probability of puncture and the product film surface smoother and free of residue, and reducing the risk of copper on the conductive rollers, thereby reducing the breakage rate of the product; therefore, the current density of the film is more uniform, and during the working process, the metal ions in the bath liquid are electrolyzed and adsorbed on the product film, thereby completing the electroplating process and completing the single-sided or double-sided electroplating of the product film.

[0038] Subsequently, after the product film enters the tank body, it passes through the conductive roller, and the tank liquid adheres to the film. During the transmission process, the film brings the tank liquid to the space between the roller and the film to form an accumulated liquid layer. The tension of the film will always run against the roller, causing the accumulated liquid to flow into the herringbone groove of the conductive roller. During the rotation process, the accumulated liquid slowly flows out along the grooves on the conductive roller, and the accumulated liquid becomes less and less until there is no accumulated liquid, so that reverse electroplating will not occur, and the risk of copper on the conductive roller will be eliminated.

[0039] The herringbone grooves of the conductive roller are coated with rubber and sprayed, and are insulated accordingly to prevent scratches and coppering on the product and avoid damage to the product. The thickness and width of the rubber coating in the herringbone grooves can be adjusted in time according to different requirements of the electroplating process, or the rubber coating can be omitted. The prepared conductive roller is suitable for various types of electroplating tanks, such as horizontal electroplating tanks, V-shaped electroplating tanks, and square electroplating tanks.

[0040] Embodiment 2:

[0041] like Figures 2 to 3c As shown, a method for grooving a grooved conductive roller for electroplating transmission components, the process is as follows:

[0042] A plurality of herringbone grooves are evenly and equally spaced from the center of the roller surface to the first shaft head surface and the second shaft head surface; or a plurality of herringbone grooves are evenly and equally spaced from the first shaft head surface and the second shaft head surface to the center of the roller surface; or a plurality of herringbone grooves are evenly and equally spaced from 0-1000mm away from the first shaft head surface or the second shaft head surface to the center of the roller surface. The specific implementation of the above method is as follows:

[0043] The method of evenly dividing a plurality of herringbone grooves from the center of the surface of the roller to the first shaft head surface and the second shaft head surface is as follows: first, a section is taken at the center of the surface of the roller, and a plurality of equal division points are taken from the edge of the section. Any equal division point is then used as the starting point for grooving, and spiral grooving is performed along the surface of the roller to extend to the first shaft head surface and the second shaft head surface respectively, with the pitch set to 10-300mm, the end point of grooving is 0-1000mm away from the first shaft head surface and the second shaft head surface, and the size of the herringbone grooves is ensured to be consistent, and the end point of grooving is determined according to the width of the product to be prepared.

[0044] The method of evenly dividing and opening a plurality of herringbone grooves from the first shaft head surface and the second shaft head surface to the center of the surface of the roller is as follows: first, a plurality of equally divided points are selected from the edge of the first shaft head surface, and then a plurality of equally divided points are selected from the plurality of equally divided points of the first shaft head surface and the plurality of equally divided points of the second shaft head surface, and then an equally divided point is randomly selected from the plurality of equally divided points of the first shaft head surface and the plurality of equally divided points of the second shaft head surface, and is used as the first grooving starting point and the second grooving starting point, and spirally grooves are respectively grooved along the surface of the roller toward the center of the surface of the roller from the first grooving starting point and the second grooving starting point, until they are connected or intersected at the center of the surface of the roller, and the size of the herringbone grooves is ensured to be consistent.

[0045] The method of evenly and equally opening a plurality of herringbone grooves from 0-1000mm away from the first shaft head surface or the second shaft head surface to the center of the roller surface is as follows: firstly, a roller section at 0-1000mm away from the first shaft head surface or the second shaft head surface is taken, a plurality of equally divided points are taken from the edge of the section, and then the equally divided points are taken as the starting points for grooving, and spiral grooves are made along the surface of the roller toward the center of the roller surface until they are connected or intersected at the center of the surface, and the size of the herringbone grooves is ensured to be consistent.

[0046] The above-mentioned grooving method also includes the process of chamfering and spraying the several herringbone grooves or chamfering without rubber coating. The process of chamfering and spraying the herringbone grooves is: first spray the herringbone grooves opened on the surface of the roller with rubber, then use the same grooving method to groove again along the original grooving track of the roller, and then polish the entire conductive roller to complete the rubber coating in the groove; this step is to groove on the rubber layer, and the width and depth of the groove are smaller than the groove described in step S1, that is, the thickness of the rubber coating in the groove is 0.05-6mm; the process of chamfering the herringbone groove without rubber coating is: after grooving using the grooving method, along the edge of the herringbone groove opened on the roller, use a chamfering tool head of R0.01mm-R5mm to chamfer the edge along the original grooving track of the surface of the roller, and make the edge of the herringbone groove smooth, and finally polish with a grinding wheel polisher or a vibration polishing tank.

[0047] The width of the herringbone groove opened in the above manner is 0.1mm-50mm, and the depth of the groove is 0.1mm-10mm; the chamfers on both sides of the herringbone groove are R0.01mm-R5mm; the connection angle of the two sides of the groove bodies of any two adjacent groups of herringbone grooves is 10°-160°, and the distance between the two groove bodies is 5mm-200mm. The shape of the groove after the herringbone groove is opened can be T-shaped, V-shaped, arc-shaped, etc., and the shape of the groove after the groove is encapsulated with rubber and then grooved again is still T-shaped, V-shaped, arc-shaped, etc.

[0048] Embodiment 3:

[0051] Type 2: V-shaped electroplating tank. One is to use five conductive rollers as a group, and the conductive rollers are staggered.

The conductive rollers are placed in a V shape and the main shaft needs to be used for transmission.

[0052] The second method is to use four conductive rollers and one transmission roller as a group. The four conductive rollers are placed in parallel, two on each side. The product film goes from the bottom of the first conductive roller to the top of the second conductive roller, then passes from the bottom of the main transmission roller below to the top of the third conductive roller, and finally passes under the fourth conductive roller. One electroplating is completed, and the conductive rollers are placed in a V shape, which requires main shaft drive.

The product film is transferred from the top of the first conductive roller to the top of the second conductive roller, and then to the bottom of the first transmission roller. After passing through the second transmission roller, the first conductive roller and the second conductive roller are on the same horizontal plane, and then go up to the top of the third conductive roller, and finally pass under the fourth conductive roller.
