Description

Technical Field

[0001] The utility model relates to the technical field of battery anode roller electroplating tanks, in particular to an electroplating tank used for electroplating battery anode rollers. Background Art

[0002] In the cell electroplating process, the anode roller serves as the conductive anode in the electroplating circuit, and its surface electroplating is of great significance for improving electroplating efficiency and coating quality.

[0003] Electroplating can form a metal coating with good conductivity on the surface of the anode roller, which helps to reduce the resistance of the anode roller during the electrolysis process, improve the current transmission efficiency, and thus enhance the overall performance of the battery.

[0004] However, in order to optimize the electroplating effect, the surface of the battery anode roller may be specially treated, such as grooving or adding a spoiler structure.

[0005] However, in the electroplating tank of the prior art, when pushing the plating solution to flow, the plating workpiece cannot be rotated, which can easily cause the turbulent flow structure on the surface of the anode roller or the flow rate of the plating solution inside the groove to be different from that on the surface of the battery anode roller. The different flow rates of the plating solution can easily cause different electrodeposition rates on the surface of the battery anode roller, resulting in uneven thickness of the surface coating, which in turn leads to reduced performance of the battery anode roller. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an electroplating tank for electroplating battery anode rollers, so as to solve the technical problems mentioned in the above background technology.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A plating tank for electroplating battery anode rollers, comprising a plating cylinder, a first insert tube rotatably provided at the inner bottom end of the plating cylinder, a plug-in provided at the upper end of the first insert tube, a guide vane provided on the outer surface of the first insert tube, a driving pump provided at the outer bottom end of the outer surface of the plating cylinder, a water inlet pipe and a drain pipe of the driving pump both inserted into the interior of the plating cylinder, an upwardly extending guide pipe provided at one end of the drain pipe inserted into the interior of the plating cylinder, and a plurality of diversion holes provided on the side wall of the guide pipe.

[0009] Furthermore, the guide pipe is rotatably connected to the drain pipe.

[0010] Furthermore, there is an intersection between the straight line direction of the water discharge from the drainage pipe and the side wall of the guide vane.

[0011] Furthermore, the water inlet pipe is arc-shaped, and the arc center of the water inlet pipe is on the same straight line as the axis of the electroplating cylinder.

[0012] Furthermore, a barrel cover is slidably provided at the upper end of the interior of the electroplating barrel, and a limiting tube is provided at a position corresponding to the barrel cover and the guide tube.

[0013] Furthermore, a second insert tube is rotatably provided at the bottom of the barrel cover.

[0014] In summary, the present invention has at least one of the following beneficial technical effects:

[0015] 1. A plating tank for electroplating a battery anode roller. A pump is driven to draw the plating solution through an inlet pipe and discharge it through a drain pipe, causing the plating solution inside the plating cylinder to flow. The guide vane is then pushed to rotate the first insert. At this time, the battery anode roller connected to the first insert via the plug-in unit rotates. The flowing plating solution and the rotating battery anode roller balance the flow rate on the surface of the battery anode roller, making the flow rate on the surface of the battery anode roller more uniform, thereby avoiding the problem of uneven plating thickness caused by excessively different flow rates on the anode roller surface.

[0016] 2. This electroplating tank for electroplating battery anode rollers has a rotatable connection between the guide pipe and the drain pipe, and a damping ring is provided at the connection. Therefore, the guide pipe can be rotated to any angle, thereby achieving the effect of adjusting the angle of the diversion hole. During use, the drainage line direction of the diversion hole is tangent to the outer peripheral wall of the anode roller, so that the electroplating solution can be evenly sprayed on the surface of the anode roller, further improving the uniformity of the electroplating solution flow on the surface of the battery anode roller.

[0017] 3. The electroplating tank for electroplating a battery anode roller is used to position the top of the battery anode roller through the arrangement of the barrel cover and the second insert, and cooperates with the first insert and the plug to improve the stability of the battery anode roller during rotation. Damping rings are provided at the connection between the first insert and the electroplating barrel and at the connection between the second insert and the barrel cover to reduce the rotation speed of the battery anode roller to avoid the problem of the plating layer burning due to the battery anode roller rotating too fast.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1-Figure 5 The utility model discloses an electroplating tank for electroplating battery anode rollers, comprising an electroplating cylinder 1, a first inserting tube 2 being rotatably provided at the bottom end of the inner portion of the electroplating cylinder 1, a damping ring 1 being provided at the connection between the first inserting tube 2 and the electroplating cylinder 1 for reducing the rotation speed of the battery anode roller, a plug-in 3 being provided at the upper end of the first inserting tube 2, a guide vane 4 being provided on the outer surface of the first inserting tube 2, a driving pump 5 being provided at the bottom end of the outer surface of the electroplating cylinder 1, a water inlet pipe 6 and a drain pipe 7 of the driving pump 5 being both inserted into the interior of the electroplating cylinder 1, an end of the drain pipe 7 inserted into the interior of the electroplating cylinder 1 being provided with an upwardly extending guide pipe 8, a plurality of diversion holes 9 being provided on the side wall of the guide pipe 8.

[0028] In this embodiment, when electroplating the battery anode roller, the battery anode roller is inserted into the insertion hole to achieve the effect of rotatably installing the battery anode roller inside the electroplating cylinder 1, and making the axis of the battery anode roller and the axis of the electroplating cylinder 1 aligned in a straight line. Then, after the electroplating solution is poured into the electroplating cylinder 1, it can contact the side wall of the battery anode roller, which can effectively prevent the battery anode roller from contacting the side wall of the electroplating cylinder 1 inward, resulting in uneven electroplating at the contact position.

[0029] After the battery anode roller is installed, the electroplating solution is sucked in through the water inlet pipe 6 by driving the pump 5, and then discharged through the drain pipe 7, so that the electroplating solution inside the electroplating cylinder 1 flows, thereby achieving the purpose of increasing the electrodeposition rate, thereby achieving the purpose of improving the electroplating efficiency of the outer surface of the battery anode roller;

[0030] When the electroplating liquid is discharged through the drain pipe 7, it pushes the guide vane 4. When the guide vane 4 is subjected to force, the first inserting tube 2 is rotated, so that the battery anode roller connected to the first inserting tube 2 through the plug 3 is rotated, so that the turbulent structure on the surface of the anode roller constantly changes its relative position in the electroplating cylinder 1, thereby achieving the purpose of increasing the relative flow rate of the anode roller and the electroplating liquid, and preventing the relative flow rate difference between the electroplating liquid and the battery anode roller surface between the turbulent structure and the grooved position and the smooth surface position is too large, which leads to the problem of excessive difference in plating thickness;

[0031] And through the setting of the guide tube 8, when the pump 5 is driven to discharge the electroplating liquid through the drain pipe 7, part of the electroplating liquid will be discharged through the guide tube 8 and the diversion hole 9 to produce an electroplating liquid with a certain pressure and flow. This part of the electroplating liquid will flow through the surface of the anode roller to further balance the flow rate of the electroplating liquid on the surface of the anode roller.

[0032] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the guide pipe 8 is rotatably connected to the drain pipe 7.

[0033] In this embodiment, since the guide tube 8 is rotatably connected to the drain pipe 7 and a damping ring is provided at the connection, the guide tube 8 can be rotated to any angle, thereby achieving the effect of adjusting the angle of the diversion hole 9. When in use, the straight line direction of the drainage of the diversion hole 9 is tangent to the outer peripheral wall of the anode roller, so that the electroplating liquid can be evenly sprayed on the surface of the anode roller.

[0034] In a further preferred embodiment of the present invention, Figure 1-5 As shown, there is an intersection between the straight line direction of water discharge from the drain pipe 7 and the side wall of the guide vane 4.

[0035] In this embodiment, since the straight direction of the water flow discharged from the drain pipe 7 intersects with the guide vane 4, when the electroplating liquid is discharged, it will contact the guide vane 4, thereby pushing the guide vane 4 to rotate and causing the electroplating cylinder 1 to rotate.

[0036] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the water inlet pipe 6 is arc-shaped, and the arc center of the water inlet pipe 6 is on the same straight line as the axis of the electroplating cylinder 1.

[0037] In this embodiment, since the water inlet pipe 6 is arc-shaped and the center of the arc is on the axis of the electroplating cylinder 1, at the same time, Figure 5 As shown, the water inlet pipe 6 and the drain pipe 7 are respectively located on both sides of the driving pump 5. When the driving pump 5 pushes the electroplating liquid inside the electroplating cylinder 1 to rotate, the direction of the electroplating liquid flow will pass through the pipe mouth of the water inlet pipe 6, so that the electroplating liquid can directly flow into the interior of the water inlet pipe 6, thereby achieving the purpose of reducing the power consumption of the driving motor.

[0038] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a barrel cover 10 is slidably provided at the upper end of the electroplating barrel 1 , and a limiting tube 11 is provided at a position corresponding to the barrel cover 10 and the guide tube 8 .

[0039] In this embodiment, the barrel cover 10 is provided to lower the height of the internal cavity of the electroplating cylinder 1, thereby reducing the amount of electroplating solution used when electroplating a shorter battery anode roller, and the limiting tube 11 is provided to locate the installation position of the barrel cover 10. When the barrel cover 10 is installed at the inner bottom end of the electroplating cylinder 1, the limiting tube 11 will be sleeved on the outer surface of the guide tube 8, and the guide tube 8 will be sealed by the inner wall of the limiting tube 11.

[0040] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a second insert tube 12 is rotatably provided at the bottom of the barrel cover 10, and a damping ring 2 is provided at the connection between the second insert tube 12 and the barrel cover 10 for reducing the rotation speed of the battery anode roller.

[0041] In this embodiment, the second inserting tube 12 is provided to position the top end of the battery anode roller, and cooperates with the first inserting tube 2 and the plug 3 to improve the stability of the battery anode roller during rotation.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
