Description

Technical Field

[0001] This utility model belongs to the technical field of electroplating equipment for automotive parts, and specifically relates to equipment for high corrosion-resistant bright tin plating of automotive parts. Background Technology

[0002] With the rapid development of the automotive industry, automotive parts face severe corrosion challenges in complex and ever-changing environments. Traditional plating technologies such as electroplating zinc and electroplating nickel have limited performance in terms of corrosion resistance and appearance. However, bright tin plating, due to its excellent corrosion resistance, good conductivity and beautiful appearance, has become an ideal choice for the surface treatment of automotive parts, meeting the modern automotive demand for high corrosion resistance and aesthetics.

[0003] Traditional equipment often uses simple stirring or manual proportioning for raw material mixing, making it difficult to accurately control the proportions of raw materials such as tin and cobalt. This results in large fluctuations in the composition of the electroplating solution, which directly causes instability in the content of various alloying elements in the coating. Consequently, it affects key properties such as the density and adhesion of the coating, leading to large fluctuations in the corrosion resistance of the coating. This makes it impossible to meet the requirements of automotive parts used in complex environments. Furthermore, since automotive parts are suspended and stationary in the electroplating tank, the uniformity of the coating is severely affected, resulting in poor electroplating effects and impacting the final molding quality of the automotive parts.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A high corrosion-resistant bright tin plating equipment for automotive parts includes an electroplating tank. Anode plates are fixedly connected to both sides of the interior of the electroplating tank. An adjustment assembly is located on one side of the electroplating tank, and a cathode clamp is located on the other side of the adjustment assembly.

[0021] refer to Figures 1 to 5The high corrosion-resistant automotive parts bright tin plating equipment described in this embodiment includes an electroplating tank 1. Anode plates 2 are fixedly connected to both sides of the interior of the electroplating tank 1. An adjustment component 4 is provided on one side of the electroplating tank 1, and a cathode clamp 3 is provided on the other side of the adjustment component 4. The anode plates 2 and the cathode clamp 3 form an electrolytic circuit, forming a tin-cobalt or tin-nickel alloy plating layer on the surface of the parts. The cathode clamp 3 is movably connected to the interior of the electroplating tank 1 via the adjustment component 4. A current density controller 6 is fixedly connected to one side of the front end of the electroplating tank 1. A pH sensor 7 and a temperature sensor 8 are fixedly connected to one side of the current density controller 6. The current density controller 6, pH sensor 7 and temperature sensor 8 on the electroplating tank 1 work together to monitor and adjust key parameters in the electroplating process in real time, ensuring a stable electroplating environment, providing a guarantee for the high-quality formation of the coating, and further improving the coating performance. A mixing component 11 is provided on one side of the electroplating tank 1. A feeding pipe 9 is fixedly connected to one side of the mixing component 11. A feeding pump 10 is fixedly connected to one side of the feeding pipe 9.

[0022] refer to Figure 1 A bracket 5 is fixedly connected to the back of the electroplating tank 1, and one side of the adjustment component 4 is fixedly connected to one side of the bracket 5. The bracket 5 is used to install the adjustment component 4 so that the adjustment component 4 can drive the cathode clamp 3 to work.

[0023] refer to Figure 3-5The cathode clamp 3 includes a fixed plate 31, which is movably connected to the lower side of the bracket 5 via an adjusting assembly 4. A first motor 32 is fixedly connected to one side of the fixed plate 31, and a lead screw 33 is fixedly connected to the output end of the first motor 32. The lead screw 33 is rotatably connected inside the fixed plate 31. Moving blocks 34 are threadedly connected to both sides of the lead screw 33. One side of the moving block 34 is slidably connected inside the fixed plate 31. A shock-absorbing spring 36 and a damper 37 are fixedly connected to both sides of one end of the moving block 34. The shock-absorbing spring 36 is sleeved on the outside of the damper 37. A clamping plate 35 is fixedly connected to the side of the shock-absorbing spring 36 and the damper 37 away from the moving block 34. A guide rod 38 is fixedly connected to the side of the clamping plate 35 near the moving block 34. A guide sleeve 39 is fixedly connected to one side of the moving block 34. One side of the guide rod 38 slides through the guide sleeve 39. The clamping plate 35 has an L-shaped structure. A fluororubber pad 351 is fixedly connected to one side of the plate 35. By setting the cathode clamp 3, when it is necessary to clamp the parts, the first motor 32 is started. The first motor 32 drives the lead screw 33 to rotate. Since the threads on both sides of the lead screw 33 are opposite and the moving block 34 is threadedly connected to the lead screw 33, when the lead screw 33 rotates, it will drive the moving blocks 34 on both sides to slide relative to each other inside the fixed plate 31 and move closer to each other. At the same time as the moving block 34 moves, it drives the clamping plate 35 fixedly connected to one side to move synchronously. The clamping plate 35 clamps and fixes the automotive parts to prevent the parts from loosening during the electroplating process. During this process, the shock-absorbing spring 36 and the damper 37 work together to play a shock-absorbing role, avoiding large clamping forces on the parts. The guide rod 38 slides in the guide sleeve 39 to stabilize the position of the clamping plate 35. The fluororubber pad 351 can closely fit the surface of the parts, disperse the pressure, effectively prevent the electroplating layer from falling off or being scratched due to excessive clamping force, and has strong corrosion resistance and long service life.

[0024] refer to Figure 2The mixing assembly 11 includes a mixer 111, which consists of a drive device, a stirring frame, etc., and can agitate the internal materials. The mixer 111 is fixedly connected to one side of the support 5, and one side of the mixer 111 is fixedly connected to one side of the feeding pipe 9. A feed pipe 113 is fixedly connected to the top of the mixer 111, and multiple feed pipes 113 are provided. A raw material storage tank 112 is fixedly connected to the upper side of the feed pipe 113, and a metering pump 114 is fixedly connected to one side of the feed pipe 113. A guide pipe 115 is fixedly connected to the top of the raw material storage tank 112. By setting the mixing assembly 11, the raw material storage tank 112 is fed through the top of the feed pipe 112... The feed pipe 115 adds the required raw materials such as tin and cobalt to the raw material storage tank 112. Different raw materials are stored in their respective raw material storage tanks 112. According to the required electroplating solution composition, the delivery volume of the metering pump 114 on each feed pipe 113 is set. The metering pump 114 draws the corresponding raw materials from the raw material storage tank 112 according to the set parameters and delivers them to the mixer 111 through the feed pipe 113. The mixer 111 fully mixes the various raw materials that enter to form a uniform electroplating solution. The feed pump 10 is started and delivers the mixed electroplating solution in the mixer 111 to the electroplating tank 1 through the feed pipe 9, providing a continuous and stable electroplating solution for the electroplating process.

[0025] refer to Figure 3-4 The adjustment component 4 includes a fixing block 41, which is fixedly connected to one side of the bracket 5. A cylinder 42 is fixedly connected to the top of the fixing block 41. A frame 43 is fixedly connected to the output end of the cylinder 42. A second motor 44 is fixedly connected to one side of the frame 43. The output end of the second motor 44 is fixedly connected to one side of the fixing plate 31. When it is necessary to send the automotive parts into the electroplating tank 1 for electroplating, the cylinder 42 is started. The cylinder 42 drives the frame 43 to move towards the electroplating tank 1 until the parts are completely immersed in the electroplating solution in the electroplating tank 1. During the electroplating process, the second motor 44 is started. The output end of the second motor 44 drives the fixing plate 31 to rotate. Specifically, the fixing plate 31 is connected to the output end of the second motor 44 through a conductive slip ring, so that the external power supply is stably transmitted to the fixing plate 31 and the clamping plate 35 of the cathode clamp 3, ensuring that the electrolytic circuit between the cathode clamp 3 and the anode plate 2 is always unobstructed. The rotation of the parts clamped by the cathode clamp 3 facilitates better reaction between the automotive parts and the active ions in the electroplating solution.

[0026] Operating principle and advantages: First, tin, cobalt, and other required raw materials are added to different raw material storage tanks 112 through the feed pipe 115 at the top of the raw material storage tank 112. Based on the required electroplating solution composition, the delivery volume of the metering pump 114 on each feed pipe 113 is set. The metering pump 114 extracts the corresponding raw materials from the raw material storage tank 112 according to the set parameters and delivers them to the mixer 111 through the feed pipe 113. The mixer 111, driven by the drive device, thoroughly agitates and mixes the raw materials to form a uniform electroplating solution. The feed pump 10 starts and delivers the mixed electroplating solution to the electroplating tank 1 through the feed pipe 9. Precise metering and thorough mixing ensure stable electroplating solution composition, avoiding errors and uneven mixing problems associated with traditional manual proportioning. Next, the automotive parts to be electroplated are placed on the cathode clamp 3. The first motor 32 is started, driving the lead screw 33 to rotate. Because the threads on both sides of the lead screw 33 are opposite, the moving blocks 34 on both sides slide relative to each other within the fixed plate 31 and move closer together, driving the clamp... The holding plate 35 moves synchronously, and the L-shaped clamping plate 35 firmly clamps the parts from different angles to prevent the parts from loosening during the electroplating process. This clamping method is flexible and adaptable to parts of different specifications, solving the problem of poor adaptability of traditional clamps. Then, the cylinder 42 drives the automotive parts to extend into the electroplating tank 1. The power is turned on so that the anode plate 2 and the cathode clamp 3 form an electrolytic circuit. The current flows out from the anode plate 2 and flows through the electroplating solution to the parts. Under the action of electrolysis, the metal ions in the electroplating solution are deposited on the surface of the parts to form a tin-cobalt or tin-nickel alloy plating layer. At the same time, the current density controller 6, pH sensor 7 and temperature sensor 8 at the front end of the electroplating tank 1 work together to monitor and adjust the current density, pH value and temperature in real time to ensure a stable electroplating environment, improve the density and adhesion of the plating layer, and avoid the instability of the plating performance caused by parameter fluctuations. During this period, the second motor 44 drives the automotive parts to rotate, so that the parts can better contact the electroplating solution, solving the problem of uneven plating caused by the static suspension of parts in traditional equipment.
