Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electroplating component processing equipment, specifically a pretreatment device for electroplating components. Background Technology
[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation such as rust, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics.
[0003] Before electroplating, the parts to be plated need to undergo activation treatment. This is done by etching with acid or alkaline solutions, dissolving the oxide film on the surface of the parts and exposing a reactive metal interface to ensure the adhesion between the electroplated layer and the substrate. However, existing pretreatment equipment uses immersion or stirring methods for activation. Immersion has poor activation effect and takes a long time, while stirring, although effective and quick, can cause impurities generated during the activation process to flow, leading to adhesion or damage to the activated parts. Therefore, we propose a pretreatment device for electroplated components. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4 A pretreatment device for electroplating components includes an activation tank 1, which consists of a tank body 11 and a platform 12. The tank body 11 is used for storing the activation solution and carrying out the activation process. A filter screen 3 is installed inside the tank body 11 to facilitate the placement and activation of the workpiece and to prevent impurities in the activation solution from affecting the workpiece. Simultaneously, the filter screen 3 is made of a flexible material, such as a polymer, which can both prevent corrosion from the activation solution and allow for flexible rotation.
[0027] A vibration mechanism 2 is provided between the activation tank 1 and the filter screen 3 to vibrate the filter screen 3, so that the filter screen can be continuously raised and lowered and stay in the tank 11 for a longer time, which promotes the renewal and mixing of the activation liquid, makes the composition of the activation liquid more uniform, and thus improves the activation effect of the workpiece.
[0028] A rotating mechanism 4 is also provided between the activation tank 1 and the filter screen 3, so that the filter screen 3 can rotate, thereby removing the impurities generated during the activation of the workpiece in the filter screen 3, and driving the workpiece to rotate, effectively avoiding the problem that impurities in the activation liquid adhere to the workpiece or cause wear to the workpiece during stirring, which ultimately affects the electroplating effect of the workpiece.
[0029] Please see Figures 1-3The vibration mechanism 2 includes two rotating frames 21, symmetrically mounted on the top of the platform 12 near both ends. A drive rod 22 is rotatably mounted through both rotating frames 21, and a motor is fixedly connected to the drive rod 22 for driving it. A vibration frame 23 is rotatably mounted on the surface of each rotating frame 21. The vibration frame 23 consists of a horizontal bar and a semi-circular arc-shaped rod. One end of the horizontal bar is connected to the rotating frame 21, and a groove 231 with a "T"-shaped cross-section is formed on the surface of the arc-shaped rod. A slider 27 is slidably mounted within the groove 231. The slider 27 consists of two cylinders and is adapted to the groove 231, allowing it to slide and rotate along the groove 231 without detaching from it.
[0030] Rotary seats 24 are fixedly installed at the center positions on both sides of the trough 11. Rotary rods 25 are rotatably mounted on the rotating seats 24. The rotating rods 25 and the drive rods 22 are connected by a transmission belt 26, so that the drive rods 22 can drive the rotating rods 25 to rotate synchronously when they work. The rotating rods 25 are rotatably connected to the sliders 27. The rotation of the rotating rods 25 drives the sliders 27 to move synchronously. The sliders 27 move along the slide grooves 231 until one end of the sliders 27 abuts against the slide grooves 231. The sliders 27 drive the vibrating frame 23 to rotate along the rotating frame 21. Since the rotation diameter of the vibrating frame 23 is larger than the rotation diameter of the rotating rods 25, the vibrating frame 23 will return to its original position after rotating a certain angle.
[0031] Simultaneously, during one full rotation of the rotating rod 25, the vibrating frame 23 spends half a rotation inside the tank 11, and the other half completes its rotational reset. This causes the filter screen 3 to continuously detach and re-enter the tank 11, promoting the renewal and mixing of the activation solution, making its composition more uniform, and thus improving the activation effect on the workpiece. Furthermore, when the vibrating frame 23 detaches from the tank 11, workpieces can be added and removed more conveniently.
[0032] A pad 28 is fixedly installed at the top of the tank 11. The pad 28 is made of a material with good shock resistance, such as rubber. The pad 28 is in contact with the vibration frame 23 to avoid rigid contact between the vibration frame 23 and the tank 11, which would affect the service life of the vibration frame 23.
[0033] Please see Figures 2-4 The rotating mechanism 4 includes multiple mounting rods 41, which are fixedly installed between two vibrating frames 23. A conveying rod 42 is rotatably mounted through the vibrating frame 23, and the conveying rod 42 is located at the connection between the crossbar and the semi-circular arc rod of the vibrating frame 23. The filter screen 3 is sleeved on the surface of all the conveying rods 42 and the mounting rods 41 and is rotatably connected to the conveying rods 42. The filter screen 3 rotates synchronously with the conveying rods 42.
[0034] The conveyor rod 42 and the drive rod 22 are connected by a transmission belt 43, allowing the drive rod 22 to drive the conveyor rod 42 to rotate synchronously, thereby causing the filter screen 3 to rotate. A brush 44 is fixedly connected between the lowest ends of the two vibrating frames 23, and the brush 44 is in contact with the surface of the filter screen 3, thereby removing impurities remaining on the surface of the filter screen 3 to prevent impurities from affecting the activation effect of the workpiece.
[0035] A pretreatment device for electroplating components operates as follows: The workpiece to be activated is added into the filter screen 3. The motor is started, driving the drive rod 22 to rotate. The drive rod 22, via a transmission belt 26, drives the rotating rod 25 to rotate along the rotating seat 24. The rotating rod 25 drives the slider 27 to rotate along the slide groove 231 until one end of the slider 27 abuts against the slide groove 231. The slider 27 then drives the vibrating frame 23 to rotate along the rotating frame 21. Because the rotation diameter of the vibrating frame 23 is larger than that of the rotating rod 25, the vibrating frame 23 returns to its original position after rotating a certain angle. This causes the filter screen 3 and the workpiece within it to continuously reciprocate, thus agitating the activation solution in the tank 11, promoting the renewal and mixing of the activation solution, making the composition of the activation solution more uniform, and thereby improving the activation effect on the workpiece.
[0036] Simultaneously, the drive rod 22 can drive the conveyor rod 42 to rotate via the transmission belt 43. The rotation of the conveyor rod 42 can cause the filter screen 3 to rotate along the mounting rod 41 and the conveyor rod 42. The filter screen 3 plays a role in isolating impurities in the activation solution, preventing impurities from affecting the activation of the workpiece. Furthermore, the filter screen 3 can also drive the workpiece to move until the workpiece flips over under the action of gravity and falls back to the bottom of the filter screen 3, which can vibrate and remove impurities generated by the activation reaction. At the same time, when the filter screen 3 rotates to the brush 44, the brush 44 can remove impurities on the surface of the filter screen 3, preventing impurities from affecting the activation reaction.
[0037] After the activation reaction is complete, the vibrating frame 23 can lift the filter screen 3 and remove it from the tank 11, making it easier to remove the workpiece.
