Description
Technical Field
[0001] This utility model belongs to the technical field of battery production and processing, and in particular relates to a plating solution circulation device for a battery steel shell barrel plating production line. Background Technology
[0002] The battery steel casing is a key metal component used to encapsulate battery cells. It requires a barrel plating process to form a uniform coating to improve corrosion resistance and conductivity. The plating solution circulation device in the barrel plating production line is the core system to ensure the quality of the coating. It is usually composed of a storage tank, filter pump, pipeline and nozzle, etc. It can realize the continuous circulation and filtration of the plating solution, which can not only prevent impurities from depositing and affecting the uniformity of the coating, but also ensure that the steel casing surface and the plating solution are in full contact through dynamic flow, thereby improving the adhesion and consistency of the coating and meeting the precision protection requirements of the battery steel casing.
[0003] However, it still has the following drawbacks in actual use: the existing battery steel shell barrel plating production line uses a rotating drum to circulate the plating solution, and then the battery steel shell moves in the drum by its own weight, so as to uniformly plate the whole body. However, the efficiency of the solution is relatively low and it is easy to have uneven plating solution. Utility Model Content
[0004] The purpose of this invention is to provide a plating solution circulation device for a battery steel shell barrel plating production line. The core of this invention is to enhance the contact effect between the plating solution and the steel shell by using a dual-power driven drum and agitator blades moving in opposite directions. At the same time, the invention is combined with a liftable drum structure and a convenient discharge component to improve production efficiency and solve problems such as low plating solution circulation efficiency and uneven plating of the steel shell during the battery steel shell barrel plating process.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a plating solution circulation device for a battery steel shell barrel plating production line, including a main component and a discharge component. The main component includes a plating solution tank and a drum. A hydraulic telescopic rod is set at the center of the upper part of the plating solution tank. A U-shaped frame is fixed at the telescopic end of the hydraulic telescopic rod. Connectors are fixed at both ends of the U-shaped frame. One of the connectors is horizontally rotatably connected to a central shaft. One end of the central shaft is fixedly connected to the center of one end of the drum. The other connector is horizontally connected to a hollow tube. One end of the hollow tube passes through the center of the drum end wall and extends into the inner cavity of the drum. The drum and the hollow tube are rotatably connected.
[0007] A drive wheel assembly is fixed at one end of the hollow tube that extends into the drum. An agitator is provided at the end of the drive wheel assembly away from the hollow tube. A second central shaft is rotatably connected to the inner cavity of the hollow tube. One end of the second central shaft is fixedly connected to the central shaft of one of the drive wheels in the drive wheel assembly.
[0008] A motor is fixed at both ends of the plating bath, and a gear is fixed on the power shaft of each motor. A gear is also fixed at the opposite ends of central shaft one and central shaft two.
[0009] Furthermore, a door panel is provided on the roller.
[0010] Furthermore, when the drum extends into the extreme position of the plating bath, the two gears located on the same side of the device mesh.
[0011] Furthermore, the motors are servo motors, and the two motor drive shafts rotate in opposite directions.
[0012] Furthermore, the discharge assembly includes a discharge hopper, with a support arm fixed on each side of the discharge hopper. The end of the support arm away from the discharge hopper is rotatably connected to the central shaft and the outer periphery of the hollow tube, respectively.
[0013] One of the support arms is fixed to a limiting component 1 on one side, and a housing is fixed to the other side of the U-shaped frame. A connecting rod is provided in the inner cavity of the housing. A limiting component 2 that matches the limiting component 1 is fixed to one end of the connecting rod. A spring is also provided on the outer periphery of the connecting rod. The two ends of the spring are fixed to the limiting component 1 and the inner wall of the housing, respectively. A handle 1 is fixed to one end of the connecting rod that protrudes from the housing.
[0014] Furthermore, a handle is fixed on each side of the discharge hopper.
[0015] This utility model has the following beneficial effects:
[0016] 1. The core of this utility model lies in the main components, which enhance the contact effect between the plating solution and the steel shell by using a dual-power driven drum and agitator blades moving in opposite directions. At the same time, the liftable drum structure and convenient discharge components improve production efficiency and solve problems such as low plating solution circulation efficiency and uneven plating of steel shells during the barrel plating process of battery steel shells.
[0017] 2. This utility model, through its designed discharge assembly, allows for the following operation: pulling handle one moves the connecting rod outward from the outer casing, at which point limiting part two separates from limiting part one. Holding handle two, the support arm rotates around the central axis one and the hollow tube, adjusting the discharge hopper to below the drum. Opening the door panel on the drum allows the steel shell inside the drum to fall into the discharge hopper under its own gravity, completing the unloading process. This solves the problem in existing solutions where the absence of a hopper makes it inconvenient to collect the battery steel shells. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0027] Please see Figures 1-5 As shown, this utility model is a plating solution circulation device for a battery steel shell barrel plating production line, including a main component 1 and a discharge component 2. The main component 1 includes a plating solution tank 11 and a drum 14. A hydraulic telescopic rod 12 is provided at the center of the upper part of the plating solution tank 11. A U-shaped frame 13 is fixed at the telescopic end of the hydraulic telescopic rod 12. Connecting parts 15 are fixed at both ends of the U-shaped frame 13. One of the connecting parts 15 is horizontally rotatably connected to a central shaft 151. One end of the central shaft 151 is fixedly connected to the center of one end of the drum 14. The other connecting part 15 is horizontally connected to a hollow tube 152. One end of the hollow tube 152 passes through the center of the end wall of the drum 14 and extends into the inner cavity of the drum 14. The drum 14 and the hollow tube 152 are rotatably connected.
[0028] The plating bath 11 in the main component 1 is used to store the plating solution. The U-shaped frame 13 is connected above it by a hydraulic telescopic rod 12. The extension and retraction of the hydraulic telescopic rod 12 can drive the U-shaped frame 13 and the roller 14 below to rise and fall as a whole. The hydraulic telescopic rod 12 is set on a large gantry linear module and is used to drive the movement of the related components of the entire roller 14. This is existing technology and will not be described in detail here.
[0029] A transmission wheel set 16 is fixed at one end of the hollow tube 152 that extends into the drum 14. A stirring blade 17 is provided at the end of the transmission wheel set 16 away from the hollow tube 152. A central shaft 153 is rotatably connected to the inner cavity of the hollow tube 152. One end of the central shaft 153 is fixedly connected to the central shaft of one of the transmission wheels in the transmission wheel set 16. A motor 18 is fixed at both ends of the plating bath 11. A gear 19 is fixed on the power shaft of each of the two motors 18. A gear 19 is fixed at the ends of the central shaft 151 and the central shaft 153 that are away from each other.
[0030] The central shaft 151 is fixed to one end of the drum 14. When the motor 18 on the left side of the plating bath 11 starts, its power shaft drives the central shaft 151 to rotate through the gear 19 (the gear 19 of the left motor 18 meshes with the gear 19 of the central shaft 151), thereby driving the drum 14 to rotate as a whole. The hollow tube 152 passes through the other end of the drum 14 and extends into the inner cavity. The central shaft 153 inside is connected to the stirring blade 17 through the transmission wheel set 16 (such as the gear 19 set or the pulley set). When the motor 18 on the right side of the plating bath 11 starts, its power shaft drives the central shaft 153 to rotate through the gear 19 (the gear 19 of the right motor 18 meshes with the gear 19 of the central shaft 153), and drives the stirring blade 17 to rotate through the transmission wheel set 16.
[0031] Furthermore, a door panel is provided on the roller 14, which is used to place the battery steel shell into the roller 14 and to remove the battery steel shell.
[0032] Furthermore, when the drum 14 extends into the extreme position of the plating bath 11, the two gears 19 located on the same side of the device mesh with each other, and the gears 19 play a transmission role, ultimately causing the motor 18 to drive the drum 14 and the stirring blade 17 to rotate.
[0033] Furthermore, the motor 18 is a servo motor, and the two motors 18 rotate in opposite directions, so that the drum 14 and the stirring blade 17 will move in opposite directions, which can significantly enhance the turbulence effect of the plating solution inside the drum 14, avoid steel shell accumulation, and improve the uniformity of the plating layer.
[0034] Furthermore, the discharge assembly 2 includes a discharge hopper 21, with a support arm 22 fixed on each side of the discharge hopper 21. The end of the support arm 22 away from the discharge hopper 21 is rotatably connected to the outer periphery of the central shaft 151 and the hollow tube 152, respectively. One side of one support arm 22 is fixed with a limiting member 23, and the U-shaped frame 13 is also fixed with a housing 25. A connecting rod 26 is provided in the inner cavity of the housing 25. One end of the connecting rod 26 is fixed with a limiting member 24 that is adapted to the limiting member 23. A spring 27 is also provided on the outer periphery of the connecting rod 26. The two ends of the spring 27 are fixed to the limiting member 23 and the inner wall of the housing 25, respectively. A handle 28 is fixed to the end of the connecting rod 26 that protrudes from the housing 25.
[0035] The discharge assembly 2 is used to quickly collect the plated battery steel shell. Pulling handle 28 causes the connecting rod 26 to move outward from the outer shell 25. At this time, the limiting member 24 separates from the limiting member 23, and the spring 27 is compressed. Holding handle 29, the support arm 22 is rotated around the central axis 151 and the hollow tube 152 to adjust the discharge hopper 21 to below the drum 14. Releasing handle 28 opens the door panel on the drum 14. The steel shell inside the drum 14 falls into the discharge hopper 21 under its own gravity, completing the unloading and greatly improving the convenience of unloading.
[0036] Furthermore, a handle 29 is fixed on both sides of the discharge hopper 21. The handle 29 is used to facilitate manual rotation of the discharge hopper 21.
[0037] The specific working principle of this utility model is as follows: When using this device, open the door panel on the drum 14, put the battery steel shell to be plated into the inner cavity of the drum 14, close the door panel and lock it to ensure that the steel shell will not fall out of the drum 14, control the extension of the hydraulic telescopic rod 12 to drive the U-shaped frame 13 and the drum 14 to descend until the drum 14 is completely immersed in the plating solution of the plating bath 11 (at this time, the drum 14 is at the limit position of being inserted into the plating bath 11). At this time, the gears 19 at the ends of the central shaft 151 and the central shaft 2 153 respectively mesh with the gears 19 of the motors 18 at both ends of the plating bath 11, providing power for the rotation of the drum 14 and the stirring blade 17.
[0038] During the barrel plating and circulation stage, two motors 18 are started. The left motor 18 drives the drum 14 to rotate clockwise, causing the internal steel shell to continuously turn over and rub against each other, reducing dead corners in the plating layer. The right motor 18 drives the central shaft 153 to rotate counterclockwise, which drives the stirring blade 17 to rotate counterclockwise through the transmission wheel set 16, stirring the plating solution inside the drum 14. Because the drum 14 and the stirring blade 17 move in opposite directions, the plating solution forms a strong circulation flow inside the drum 14, which not only ensures the uniform concentration of the plating solution, but also allows the surface of the steel shell to fully contact the plating solution, improving the quality of the plating layer.
[0039] During the unloading preparation stage, after the barrel plating is completed, the motor 18 is turned off, the hydraulic telescopic rod 12 is controlled to retract, and the roller 14 is driven to rise above the plating bath 11, so that the gear 19 is disengaged and the motor 18 is not subjected to unloaded force.
[0040] The discharge assembly 2 is used to quickly collect the plated battery steel shell. Pulling handle 28 causes the connecting rod 26 to move outward from the outer shell 25. At this time, the limiting member 24 separates from the limiting member 23, and the spring 27 is compressed. Holding handle 29, rotate the support arm 22 around the central axis 151 and the hollow tube 152 to adjust the discharge hopper 21 to below the drum 14. Release handle 28, the spring 27 resets and pushes the limiting member 24 to re-engage with the limiting member 23, fixing the position of the discharge hopper 21. Open the door panel on the drum 14, and the steel shell inside the drum 14 falls into the discharge hopper 21 under its own gravity, completing the unloading.
[0041] This utility model achieves lifting control of the drum 14 through the hydraulic telescopic rod 12. With the drum 14 driven by the dual motors 18 and the stirring blades 17 moving in opposite directions, it significantly improves the efficiency of plating solution circulation and the uniformity of the steel shell coating. At the same time, the rotatable design and limiting structure of the discharge component 2 simplify the unloading process and are suitable for mass production scenarios.
[0042] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
