Description

Technical Field

[0001] This utility model relates to the field of copper sheet processing technology, specifically to an automatic device for washing copper connecting sheets. Background Technology

[0002] The production process of copper-plated nickel connectors used in new energy vehicle batteries mainly includes copper cutting, surface pretreatment, nickel plating, and post-treatment. First, high-purity copper strips are precision stamped and cut into connector blanks of the designed size. Then, the surface treatment stage is carried out: alkaline degreasing agents are used to remove oil stains from the surface of the copper sheets. Next, an acid pickling process is carried out, usually using dilute sulfuric acid or mixed acid to dissolve the oxide layer and activate the metal surface.

[0003] Rinsing after pickling is a crucial step in determining product quality. If the residual acidic solution and reaction products on the surface of the copper sheet after acid etching are not thoroughly removed, it will directly affect the uniformity and adhesion of the subsequent nickel plating layer. Residual acid can cause pH imbalance in the nickel plating bath, leading to defects such as pinholes and blistering in the plating layer. Simultaneously, acidic substances may react with nickel ions, forming impurities trapped in the plating layer and reducing conductivity. Furthermore, unwashed acidic media can concentrate during the drying process, potentially corroding the copper substrate and forming dark spots, affecting the product's appearance and corrosion resistance. From an environmental perspective, thorough rinsing reduces the amount of acidic substances introduced into subsequent processes, lowers wastewater treatment pressure, and avoids cross-contamination. Therefore, repeated rinsing with clean water ensures that the pH value of the copper sheet surface is close to neutral, creating ideal substrate conditions for the nickel plating process.

[0004] The authorization announcement number CN222175119U discloses a tin-plated copper busbar processing device. According to its instruction manual and drawings, the device is designed with a frame plate, a mesh frame and a limiting strip, which allows copper busbars to be placed vertically for cleaning and rinsing, and multiple copper busbars to be placed separately without contacting each other.

[0005] However, this cleaning method still has certain limitations: 1. After cleaning, the equipment cannot automatically remove the copper busbars from the water, resulting in the need for manual removal of a large amount of excess water from the surface of the copper busbars; 2. The copper busbars have been acid-washed before water washing, and if they are manually transported to the water washing process, it will cause certain harm to the human body. Therefore, ensuring the degree of automation in the production process is also one of the issues that need to be considered. Summary of the Invention

[0006] This invention addresses the problems existing in the washing of copper connecting pieces or copper drains. It provides an automatic device for washing copper connecting pieces. After the nickel-plated copper connecting pieces inside the copper sheet placement plate are washed, the height of the entire washing chamber is adjusted by the angle adjustment mechanism, and the cleaning nozzle is stopped at the same time. At this time, the copper sheet placement plate is automatically removed from the water source, and the water remaining on the surface of the copper sheet placement plate drips into the water storage tank.

[0007] The objective of this invention is achieved through the following technical solution: an automatic device for washing copper connecting plates, comprising a conveying mechanism for conveying copper plates, a transmission mechanism for controlling the operation of the conveying mechanism on the side of the conveying mechanism, a lifting mechanism for changing the height of the conveying mechanism below the conveying mechanism, a copper plate placement plate that can slide inside the conveying mechanism, a washing mechanism for storing and washing the copper plate placement plate on one side of the conveying mechanism, the angle of the washing mechanism being changed by an angle adjustment mechanism connected to the top, and a water tank at the bottom of the washing mechanism.

[0008] Preferably, the conveying mechanism includes a conveying support frame, first rollers and roller assemblies. The conveying support frame has a plurality of first rollers rotatably disposed inside, and a plurality of first sliding guides are disposed on the inner side of the conveying support frame. Each first sliding guide is provided with a roller assembly inside, and the end of each roller assembly is connected to the surface of the copper sheet placement plate.

[0009] Preferably, the roller assembly includes a rolling support column, a metal bearing, and a rolling bushing. The surface of the rolling support column is provided with a plurality of metal bearings, and the surface of the metal bearings is fitted with a rolling bushing, which fits into the interior of the first sliding guide rail.

[0010] Preferably, the transmission mechanism includes a first transmission gear and a first drive motor. One end of each first roller shaft extends outward and is provided with a first drive connecting post. The surface of each first drive connecting post is provided with a first transmission gear. Adjacent first transmission gears are connected by chain transmission. At least one end of the first drive connecting post is also connected to a first drive motor.

[0011] Preferably, the lifting mechanism includes a lifting support frame, a guide rod support sleeve, a lifting cylinder, and a metal guide rod. The lifting support frame has several guide rod support sleeves and lifting cylinders inside. Each guide rod support sleeve has a metal guide rod that can slide inside. The top of each metal guide rod and the top of the piston rod of the lifting cylinder are connected to the bottom of the conveying support frame. This arrangement is for changing the height of the conveying mechanism.

[0012] Preferably, the washing mechanism includes a washing chamber, a second sliding guide rail, a second roller shaft, a second drive connecting column, a second transmission gear, and a second drive motor. The bottom of the washing chamber is rotatably connected to the top of the water storage tank. The interior of the washing chamber is provided with several second sliding guide rails and a second roller shaft. The end of the second roller shaft extends outward to provide a second drive connecting column. The surface of each second drive connecting column is provided with a second transmission gear. Adjacent second transmission gears are connected by chain drive. At least one end of the second drive connecting column is connected to a second drive motor. The angle adjustment mechanism can adjust the angle of the washing chamber so that the second sliding guide rail is aligned with the first sliding guide rail.

[0013] Preferably, the interior of the washing chamber is provided with several water passage holes, and the top of the washing chamber is provided with several cleaning nozzles. Each cleaning nozzle is connected to an external water pipe. This arrangement is to enable the cleaning of the copper-plated nickel connecting pieces inside the copper sheet placement plate inside the washing chamber.

The end of the metal suspension wire is connected to the top of the washing chamber through an adjusting connecting frame. A third drive motor is provided on one side of the wire winding reel. The rotation of the shaft of the third drive motor can drive the wire winding reel to rotate.

[0015] Compared with the prior art, this utility model has the following beneficial effects: 1. After the copper-plated nickel connecting pieces inside the copper sheet placement plate are washed with water, the height of the entire washing chamber is adjusted by the angle adjustment mechanism, and the cleaning nozzle is stopped at the same time. At this time, the copper sheet placement plate is automatically separated from the water source, and the water remaining on the surface of the copper sheet placement plate will drip into the water storage tank. This not only saves time for workers to wipe off excess water, but also effectively avoids workers from coming into contact with the mixture of water and pickling solution, thus improving production safety; 2. The height of the conveying mechanism can be changed by the lifting mechanism. There is a large gap between the end of the conveying mechanism and the end of the washing mechanism, which allows manual or robotic arms to grab the cleaned copper sheet placement plate, bringing convenience to the production process.

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0023] like Figures 1 to 5 As shown, an automatic water washing device for copper connecting pieces includes a conveying mechanism 1 for conveying copper pieces, a transmission mechanism 2 for controlling the operation of the conveying mechanism 1 on its side, and a copper piece placement plate 4 that can slide inside the conveying mechanism 1.

[0024] In this embodiment, the conveying mechanism 1 includes a conveying support frame 11, a first roller shaft 12, and a roller assembly 14. The conveying support frame 11 has a plurality of first roller shafts 12 rotatably arranged inside. The inner side of the conveying support frame 11 is provided with a plurality of first sliding guide rails 13. Each first sliding guide rail 13 has a roller assembly 14 inside. The end of each roller assembly 14 is connected to the surface of the copper sheet placement plate 4.

[0025] Before water washing, the copper sheet or copper plate needs to be acid-washed. The copper sheet placement plate 4 is made of glass. During the previous acid washing process, the copper sheet is already stuck inside the copper sheet placement plate 4. After acid washing is completed, the entire copper sheet placement plate 4 is placed inside the first sliding guide rail 13 by a robotic arm or a cylinder.

[0026] The transmission mechanism 2 includes a first transmission gear 21 and a first drive motor 22. One end of each first roller 12 extends outward and is provided with a first drive connecting post 121. The surface of each first drive connecting post 121 is provided with a first transmission gear 21. Adjacent first transmission gears 21 are connected by chain transmission. At least one end of the first drive connecting post 121 is also connected to the first drive motor 22.

[0027] The rotating shaft of the first drive motor 22 can drive the first drive motor 22 to rotate during rotation. The first drive motor 22 simultaneously drives the first roller shaft 12 to rotate. Several first roller shafts 12 rotate simultaneously through a chain, causing the copper sheet placement plate 4 on the surface of the first roller shaft 12 to slide inside the first sliding guide rail 13.

[0028] The roller assembly 14 includes a rolling support column 141, a metal bearing 142 and a rolling bushing 143. The surface of the rolling support column 141 is provided with a plurality of metal bearings 142, and the surface of the metal bearings 142 is fitted with a rolling bushing 143. The rolling bushing 143 fits into the interior of the first sliding guide rail 13.

[0029] During the sliding process of the copper sheet placement plate 4 inside the first sliding guide rail 13, the rolling bushing 143 is in contact with the inside of the first sliding guide rail 13 and rolls continuously. During the rolling process, the metal bearing 142 is used for support and guidance. The rolling bushing 143 drives the entire copper sheet placement plate 4 to move through the rolling support column 141.

[0030] In this embodiment, a water washing mechanism 5 for storing and washing copper busbar placement plates is provided on one side of the conveying mechanism 1. The angle of the water washing mechanism 5 is changed by the angle adjustment mechanism 6 connected to the top, and a water storage tank 7 is provided at the bottom of the water washing mechanism 5.

[0031] The washing mechanism 5 includes a washing chamber 51, a second sliding guide rail 52, a second roller shaft 53, a second drive connecting column 531, a second transmission gear 54, and a second drive motor 55. The bottom of the washing chamber 51 is rotatably connected to the top of the water storage tank 7. The interior of the washing chamber 51 is provided with several second sliding guide rails 52 and second roller shafts 53. The ends of the second roller shafts 53 extend outward to provide second drive connecting columns 531. The surface of each second drive connecting column 531 is provided with a second transmission gear 54. Adjacent second transmission gears 54 are connected by chain drive. At least one end of the second drive connecting column 531 is connected to a second drive motor 55. The angle adjustment mechanism 6 can adjust the angle of the washing chamber 51 so that the second sliding guide rail 52 is aligned with the first sliding guide rail 13. The interior of the washing chamber 51 is provided with several water passage holes 511, and the top of the washing chamber 51 is provided with several cleaning nozzles 56. Each cleaning nozzle 56 is connected to an external water pipe.

[0032] As the copper sheet placement plate 4 is continuously conveyed, the angle adjustment mechanism 6 first adjusts the angle of the washing chamber 51 so that the second sliding guide rail 52 is aligned with the first sliding guide rail 13. Then, the shaft of the second drive motor 55 drives a second roller 53 to rotate via the second drive connecting column 531. Adjacent second rollers 53 are connected by a chain drive on the second transmission gear 54, so that each second roller 53 rotates simultaneously.

[0033] Under the rotational engagement between the first roller 12 and the second roller 53, the copper sheet placement plate 4 can slide from the inside of the first sliding guide rail 13 to the inside of the second sliding guide rail 52. Then, the angle adjustment mechanism 6 gradually lowers the angle of the entire washing chamber 51. At this time, the copper sheet placement plate 4 slides to the innermost part of the washing chamber 51 under the guidance of gravity and the second sliding guide rail 52. After sliding to the designated position, the cleaning nozzle 56 begins to rinse the residual pickling solution on the surface of the copper sheet placement plate 4. The rinsed water flows into the water storage tank 7 through the water passage 511 and is centrally treated. At this time, due to...

[0034] The angle adjustment mechanism 6 includes a wire winding reel 61, a boom 62, wire guide rollers 63, a metal suspension wire 64, and a third drive motor 65. A metal support plate 71 is provided on the side of the water tank 7. The surface of the metal support plate 71 is provided with the wire winding reel 61 and the boom 62. The top of the boom 62 and the surface of the metal support plate 71 are provided with several wire guide rollers 63. The surface of the wire guide rollers 63 is provided with a metal suspension wire 64 wound around the wire winding reel 61. The end of the metal suspension wire 64 is connected to the top of the washing chamber 51 through an adjusting connecting frame. A third drive motor 65 is provided on one side of the wire winding reel 61. The rotating shaft of the third drive motor 65 can drive the wire winding reel 61 to rotate during rotation.

[0035] When the angle of the washing chamber 51 needs to be adjusted, the shaft of the third drive motor 65 drives the wire winding reel 61 to rotate. The change in the angle of the wire winding reel 61 enables the winding and unwinding of the metal hanging wire 64. During the winding and unwinding process of the metal hanging wire 64, the wire guide roller 63 plays a supporting and guiding role. The metal hanging wire 64 is suspended by the adjusting connecting frame, and the winding and unwinding of the metal hanging wire 64 causes the angle of the washing chamber 51 to change.

[0036] In this embodiment, a lifting mechanism 3 capable of changing the height of the conveying mechanism 1 is provided below the conveying mechanism 1.

[0037] The lifting mechanism 3 includes a lifting support frame 31, a guide rod support sleeve 32, a lifting cylinder 33, and a metal guide rod 34. The lifting support frame 31 is provided with a plurality of guide rod support sleeves 32 and lifting cylinders 33 inside. Each guide rod support sleeve 32 is slidably provided with a metal guide rod 34 inside. The top of each metal guide rod 34 and the top of the piston rod of the lifting cylinder 33 are connected to the bottom of the conveying support frame 11.

[0038] After the washing process is complete, the piston rod of the lifting cylinder 33 retracts, thereby lowering the height of the conveying mechanism 1 relative to the ground. Then, the metal suspension cable 64 readjusts the angle of the washing chamber 51, causing the copper sheet placement plate 4 inside the washing chamber 51 to slide downwards. At this time, there is a large gap between the end of the conveying mechanism 1 and the end of the washing mechanism 5, allowing manual or robotic arms to grab the cleaned copper sheet placement plate 4.

[0039] Working principle and usage of this utility model:

[0040] The entire copper sheet placement plate 4 is placed inside the first sliding guide rail 13. Then, the rotating shaft of the first drive motor 22 drives the first drive motor 22 to rotate during rotation. The first drive motor 22 simultaneously drives the first roller shaft 12 to rotate. Several first roller shafts 12 rotate simultaneously through a chain, causing the copper sheet placement plate 4 on the surface of the first roller shaft 12 to slide inside the first sliding guide rail 13.

[0041] As the copper sheet placement plate 4 is continuously conveyed, the angle adjustment mechanism 6 first adjusts the angle of the washing chamber 51 so that the second sliding guide rail 52 is aligned with the first sliding guide rail 13. Then, the shaft of the second drive motor 55 drives a second roller 53 to rotate via the second drive connecting column 531. Adjacent second rollers 53 are connected by a chain drive on the second transmission gear 54, so that each second roller 53 rotates simultaneously.

[0042] With the rotational engagement between the first roller 12 and the second roller 53, the copper sheet placement plate 4 can slide from the inside of the first sliding guide rail 13 to the inside of the second sliding guide rail 52. Then, the angle adjustment mechanism 6 gradually lowers the angle of the entire washing chamber 51. At this time, the copper sheet placement plate 4 slides to the innermost part of the washing chamber 51 under the guidance of gravity and the second sliding guide rail 52. After sliding to the designated position, the cleaning nozzle 56 begins to rinse the residual pickling solution on the surface of the copper sheet placement plate 4. The rinsed water flows into the water storage tank 7 through the water passage 511 for centralized treatment.

[0043] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
