Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically a pretreatment device for electroplating. 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 and corrosion, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics.

[0003] Before electroplating, metal parts need to undergo a series of pretreatments, including polishing, degreasing, and etching, to make their surfaces smooth and clean, thereby achieving the best electroplating effect. However, traditional metal parts pretreatment devices are all independent, and each step must be transferred before proceeding to the next step, which greatly delays the electroplating efficiency.

[0018] 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.

[0019] This utility model provides a pretreatment device for electroplating, such as... Figure 1-4 As shown, the pretreatment device for electroplating includes a base 1, a bracket 2 fixedly mounted on the upper end of the base 1, a drive motor 3 mounted on the bracket 2, a drive component 4 mounted on the output shaft of the drive motor 3, two sets of driven wheels 5 mounted on the left and right sides of the upper end of the base 1, a conveyor chain 6 sleeved on the four sets of driven wheels 5, the lower end of the drive component 4 connected to the conveyor chain 6, a clamping component provided on the conveyor chain 6, and a pretreatment component provided on the base 1.

[0020] In actual operation, the drive motor 3 starts, driving the drive component 4 to rotate. The drive component 4 then drives the conveyor chain 6 to circulate on the four sets of driven wheels 5. The clamping component transfers the metal parts. When it moves to the appropriate position, it can clamp or release the metal parts. The protective pads glued to the opposite side of the grippers 12 can prevent the metal parts from being pinched. When the pretreatment component is working, it cleans the metal parts and removes the rust from the surface of the metal parts, and dries the metal parts quickly.

[0021] The clamping assembly includes a mounting component 7, which is fixedly mounted on the conveyor chain 6. Two sets of pulleys 8 are mounted on the upper end of the conveyor chain 6, and a slide rail 9 is mounted on the upper end of the bracket 2. The two sets of pulleys 8 are slidably mounted on the slide rail 9. An electric telescopic rod 10 is fixedly mounted on the lower end of the mounting component 7. A pneumatic clamp 11 is mounted on the telescopic end of the electric telescopic rod 10, and two sets of grippers 12 are mounted on the lower end of the pneumatic clamp 11.

[0022] When it is necessary to clamp a metal part, the electric telescopic rod 10 extends downward, driving the pneumatic clamp 11 and the jaws 12 to move downward to the appropriate position. The pneumatic clamp 11 is activated, controlling the relative movement of the two sets of jaws 12 to firmly clamp the metal part. Then the electric telescopic rod 10 retracts upward, driving the clamped metal part to rise. At the same time, the pulley 8 slides on the slide rail 9 to ensure that the clamping assembly can move smoothly and accurately along the preset path.

[0023] The pretreatment assembly includes a water pump 13, which is fixedly mounted on a base 1. A filter 14 is mounted on the upper side of the base 1 and connected to the water pump 13. A rust removal box 15 is mounted on the upper side of the base 1, and a vibration pump 16 is fixedly mounted on the rust removal box 15. A water supply pipe 17 is fixedly mounted on the lower end of the filter 14. A cleaning box 18 is mounted on the upper side of the base 1. A cleaning trough 19 is provided in the right end of the cleaning box 18. A nozzle 20 is installed in the cleaning trough 19 and connected to the left end of the water supply pipe 17.

[0024] When the metal part is conveyed to the top of the rust removal box 15 by the clamping assembly, the vibration pump 16 starts and the high-frequency vibration causes the rust removal liquid in the rust removal box 15 to fully contact the surface of the metal part, effectively removing stubborn rust. After rust removal, the metal part continues to move to the cleaning box 18 area with the conveyor chain 6. At this time, the water pump 13 starts to work and delivers the filtered cleaning water to the nozzle 20 through the water pipe 17. The nozzle 20 sprays water evenly on the surface of the metal part to thoroughly wash away the residual rust removal liquid and impurities.

[0025] A hot air blower 21 is fixedly installed on the upper side of the base 1. An air supply pipe 22 is installed at the air outlet of the hot air blower 21. A drying trough 23 is provided inside the left end of the cleaning box 18. Multiple sets of air knives 24 are fixedly installed inside the drying trough 23. The air knives 24 are fixedly connected to the air supply pipe 22.

[0026] The hot air generated by the hot air blower 21 is delivered to multiple sets of air knives 24 in the drying tank 23 through the air duct 22. The air knives 24 transform the hot air into a uniform and high-speed airflow curtain through a specially designed slit structure, which can quickly penetrate the water film on the surface of the metal parts, while avoiding physical impact on the metal parts, ensuring that the drying process is efficient and does not damage the workpiece.

[0027] The inner walls of both the washing tank 19 and the drying tank 23 are lined with polyurethane cushioning pads.

[0028] Polyurethane buffer pads have good elasticity and wear resistance. When the clamping assembly puts the metal parts into the cleaning tank 19 or drying tank 23, if a slight collision occurs, the buffer pads can effectively absorb the impact force, prevent the metal parts from directly contacting the tank wall and causing damage, and at the same time reduce the vibration and noise generated during equipment operation, thus extending the service life of the equipment.

[0029] The two sets of grippers 12 at the lower end of the pneumatic clamp 11 are each glued with a protective pad on one side of their opposite sides.

[0030] The protective pad is made of highly elastic and wear-resistant rubber material. The surface is specially treated to have anti-slip and anti-aging properties. During the clamping of metal parts, the protective pad can not only increase the friction between the gripper 12 and the metal parts to prevent the metal parts from slipping, but also prevent the gripper 12 from directly contacting the surface of the metal parts to prevent scratches or leaving clamp marks, ensuring that the metal parts remain intact during the pretreatment process.

[0031] Working principle: This pretreatment device for electroplating drives the conveyor chain 6 via the drive motor 3. The clamping components on the conveyor chain 6 move accordingly. When it reaches the metal part storage position, the electric telescopic rod 10 extends downward, allowing the pneumatic clamp 11 and gripper 12 to reach the appropriate height. The pneumatic clamp 11 controls the relative movement of the gripper 12 to clamp the metal part. Then, the electric telescopic rod 10 retracts upward, raising the metal part. The pulley 8 slides on the slide rail 9, smoothly conveying the metal part to the top of the rust removal box 15. At this time, the vibration pump 16 starts, and the rust removal liquid in the rust removal box 15 vibrates. Under the action of the cleaning agent, the metal parts are fully contacted to remove rust. Then the clamping assembly continues to move and send the metal parts into the cleaning tank 19. The water pump 13 delivers water purified by the filter 14 to the nozzle 20 through the water pipe 17. The nozzle 20 uses high-pressure water to rinse the metal parts and thoroughly remove residual rust remover and impurities. After cleaning, the clamping assembly moves again and sends the metal parts into the drying tank 23. The hot air generated by the hot air blower 21 is delivered to the air knife 24 through the air pipe 22. The air knife 24 converts the hot air into a uniform and high-speed airflow curtain to quickly dry the moisture on the surface of the metal parts.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
