Description

Technical Field

[0001] The invention relates to the technical field of electroplating of automobile parts, in particular to a continuous selective plating device for automobile parts based on coaxial displacement. Background Art

[0002] In the automotive manufacturing industry, electroplating of auto parts is a key process to ensure their corrosion resistance, wear resistance, and aesthetics. However, traditional electroplating equipment for auto parts has many drawbacks that are difficult to overcome during actual production, seriously restricting the efficient and high-quality development of auto parts electroplating production. From a production process perspective, most traditional equipment uses an intermittent loading, plating, and unloading method. This method requires the equipment to pause during each work cycle to load and unload, affecting the overall production schedule of the vehicle. In terms of equipment structure, traditional electroplating equipment has a complex design, often integrating multiple independent mechanical units and control systems. Daily operation processes are cumbersome, and the complex structure also leads to a high equipment failure rate, causing production interruptions and further reducing production efficiency. Specifically speaking of different types of traditional electroplating equipment, the common drum-type electroplating equipment can achieve batch processing of a certain number of parts. However, due to the limited internal space of the drum and the single movement mode, the parts collide and rub against each other, which can easily cause surface damage. In actual production, the parts treated by the drum-type electroplating equipment are prone to surface scratches and wear, affecting product quality. Moreover, due to the different contact time and degree between the parts at different positions in the drum and the electroplating solution, it is impossible to guarantee the consistent electroplating time and electroplating effect for each part, resulting in uneven product quality. Although rack plating equipment can better control the electroplating process of individual accessories, there are too many manual operation links in loading and unloading, which not only consumes a lot of manpower costs, but also easily leads to operational errors due to human factors, affecting production efficiency and product quality. During manual loading, if the hanging position of the accessories is not accurate, it will lead to uneven electroplating. During manual unloading, if the operation is not timely, the accessories will stay in the electroplating solution for too long or too short, which will also affect the electroplating effect. Summary of the Invention

[0003] The purpose of the present invention is to provide a continuous selective plating equipment for automobile parts based on coaxial displacement, so as to solve the problems proposed in the above background technology, such as insufficient production capacity caused by intermittent production, high procurement cost due to complex equipment structure, cumbersome operation, high failure rate, and efficiency and quality defects of traditional drum-type and rack plating equipment.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: a coaxial displacement-based continuous selective plating device for auto parts, comprising an electroplating tank, a conveyor belt provided on one side of the electroplating tank, and baffles provided on both sides of the conveyor belt, the baffles on both sides of the conveyor belt having different heights, and the baffle closer to the electroplating tank being lower than the other baffles, a continuous loading mechanism provided at the upper end of the electroplating tank, which simultaneously realizes the loading, electroplating, and unloading processes by coaxial rotation of the auto parts and rotation during revolution, and the continuous loading mechanism is designed with the upper end of the mechanism tilted toward the conveyor belt; The continuous feeding mechanism includes a feeding box, which is fixedly arranged on the upper surface of one end of the electroplating tank, and the upper end of the electroplating tank on one side of the feeding box is fixedly connected to a directional plate, and the lower end of the directional plate is fixedly connected to a feeding rod, a feeding motor is fixedly installed on the outer surface of the lower end of the feeding box, and a rotating pushing rod is installed inside the lower end of the feeding box, a center block is fixedly arranged on the outer surface of one side of the feeding box, and a center slip ring is fixedly arranged on the outer surface of the center slip ring, and a rotating swivel is installed on the outer surface of the center slip ring, a hanging bracket is fixedly arranged on the outer surface of the swivel, and one end of the hanging bracket is fixedly connected to the hanging rod; The continuous feeding mechanism also includes: a material resistance rod, which is fixedly arranged at the upper end of one side of the electroplating tank, and the upper end of the material resistance rod is opposite to the lower end of the discharge rod, and the upper end of the material resistance rod is fixedly provided with a material resistance plate, the outer surface of the discharge box is fixedly provided with a function plate, and one end of the function plate is fixedly connected with a repulsion magnet, the upper surface of the end of the function plate connected to the discharge box is fixedly provided with a switching motor, and one end of the output shaft of the switching motor is fixedly connected with a switching gear, a hanging jig is hung on the outer surface of the hanging rod, the lower end of the hanging jig is engaged with the workpiece, the upper end side surface of the hanging jig is provided with a give way groove, and the upper end side surface of the hanging jig is fixedly provided with a functional magnet, and a discharging rod is fixedly provided on the upper end surface of the electroplating tank facing the conveyor belt; The outer surfaces of the discharging rod and the lowering rod are hung with hanging jigs.

[0005] Preferably, the oriented plate is L-shaped, and one end side surface of the oriented plate is in contact with the outer surface of the blanking box, and the thickness of the oriented plate is the same as the width of the clearance groove.

[0006] The above technical solution enables the hanging jig to be accurately positioned when it is hung on the unloading rod through the cooperation of the directional plate and the clearance groove, ensuring the stability and accuracy of the hanging jig during subsequent movement, preventing it from shaking or shifting at will, and thus providing a guarantee for the smooth progress of the loading process.

[0007] Preferably, a spiral blade is fixedly provided on the outer surface of the push rod, and the rotating shaft of the push rod is fixedly connected to the output shaft of the blanking motor.

[0008] By adopting the above technical solution, when the unloading motor drives the push rod to rotate, the spiral blades can push the suspended jigs hanging on the unloading rod one by one and stably toward the resisting rod, realizing intermittent and orderly loading operation, improving the efficiency and accuracy of loading, and avoiding jamming or chaos caused by pushing multiple suspended jigs at the same time during the loading process.

[0009] Preferably, one end of the hanger is U-shaped, and the hanger is rotatably connected to the suspension jig through a hanging rod, and the diameter of the hanging rod is larger than the width of the makeshift groove, and the thickness of the hanger is the same as the width of the makeshift groove.

[0010] With the above technical solution, the U-shaped design facilitates the hanging jig to be hung by engaging with the hanging rod through the clearance groove, ensuring the reliability of the connection. The diameter of the hanging rod is larger than the width of the clearance groove to prevent the hanging jig from accidentally detaching from the hanging rod during rotation, thereby ensuring the stable progress of the electroplating process.

[0011] Preferably, the width of the end where the functional plate is connected to the repulsive magnet is smaller than the width of the U-shaped opening of the bracket, the width of the repulsive magnet is smaller than the width of the U-shaped groove of the bracket, and the magnetic poles of the end facing the repulsive magnet and the functional magnet are the same.

[0012] By adopting the above technical solution, the size design of the functional plate and the repulsive magnet allows them to be close to the hanging jig without interfering with each other without affecting the normal operation of the hanger. The repulsive force generated by the repulsive magnet and the functional magnet having the same magnetic pole can adjust the hanging jig to a vertical downward state after the hanging jig is connected to the hanger, ensuring that the surface of the workpiece can evenly contact the plating liquid during the electroplating process, thereby ensuring the quality of electroplating.

[0013] Preferably, the outer surface of the rotating ring facing the switching gear is evenly provided with tooth blocks, and the switching gear is meshed and connected with the rotating ring through the tooth blocks on the outer surface of the rotating ring.

[0014] By adopting the above technical solution, when the switching motor drives the switching gear to rotate, the rotation speed and angle of the swivel can be accurately controlled by meshing with the tooth block on the outer side of the swivel, thereby accurately controlling the time and position of the suspended jig and workpiece entering the electroplating tank, meeting the time and position accuracy requirements of different electroplating processes, and ensuring the accuracy and stability of the electroplating process.

[0015] Preferably, the upper end of the discharging rod is designed as a round rod with a plate-shaped protrusion on one side, and the thickness of the plate-shaped protrusion on one side of the upper end of the discharging rod is the same as the thickness of the give way groove, and the lower end of the discharging rod is located above the conveyor belt between the two baffles.

[0016] By adopting the above technical solution, the plate-shaped protrusion at the upper end of the discharge rod cooperates with the give way groove. When the suspended jig revolves to the position of the discharge rod with the swivel, the suspended jig is guided to slide smoothly down under the action of gravity. The lower end of the discharge rod is located above the conveyor belt, and the baffles on both sides of the conveyor belt are at different heights, which facilitates the suspended jig and workpiece to slide onto the conveyor belt, realizing automatic unloading and improving the degree of automation and production efficiency of production.

[0017] Preferably, the hanging jig hung on the outer surface of the blanking rod is inverted, and the hanging jig hung on the outer surface of the blanking rod is engaged with the spiral blades on the outer surface of the push rod, and the outer surface of the hanging jig hung on the outer surface of the blanking rod is in contact with the inner surface of the blanking box.

[0018] By adopting the above technical solution, the inverted hanging jig is convenient for the spiral blades of the push rod to push it to move. At the same time, the fit with the inner surface of the discharge box can prevent the hanging jig from shaking during movement. The locking installation with the spiral blades of the push rod ensures that the hanging jig can be pushed stably when the push rod rotates, providing a guarantee for continuous and efficient loading.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the continuous selective plating equipment for automobile parts based on coaxial displacement: 1. The unloading box and the intermittent rotation of the push rod enable the hanging jig and workpiece hung on the unloading rod to be pushed toward the push rod one by one. The push rod and the push plate position the hanging jig so that it can be connected to the hanger that revolves with the rotating ring. This allows the hanging jig and workpiece to enter the electroplating tank for electroplating during the rotation of the rotating ring. The loading process does not require complicated operations, thereby improving processing efficiency. 2. The repulsive magnet and the functional magnet are used to adjust the angle of the hanging jig after it slides into place, so that the workpiece can always remain in a vertical downward position under the push of the repulsive force and the action of gravity after loading is completed, thereby ensuring the stability of the electroplating quality of the workpiece surface during the subsequent electroplating process; Furthermore, the hanging jig is rotated relative to the hanging rod during the revolution of the rotating ring, so that when the hanging jig is displaced to the discharge rod, it can slide down through the discharge rod under the action of the neutral position, and the purpose of automatic unloading is achieved in conjunction with the setting of the conveyor belt. At the same time, the setting of the yield groove prevents the hanging jig from being disconnected from the hanging rod when it is rotated into place, thereby ensuring the stability of the electroplating process.

The diameter of the hanger rod 13 is larger than the width of the clearance groove 22, and the thickness of the hanger 12 is the same as the width of the clearance groove 22. Before starting the equipment, the auto parts to be electroplated are mounted on the hanging jig 20. The hanging jig 20 engages with the oriented plate 5 and the blanking rod 6 through the clearance groove 22 and is hung upside down on the blanking rod 6. As gravity drives the hanging jig 20 down along the blanking rod 6, the outer surface of the hanging jig 20 is in contact with the inner surface of the blanking box 4 and one end of the hanging jig 20 engages with the spiral blade of the push rod 8. The swivel 11 is mounted on the outer surface of the center slip ring 10 and can rotate around the center block 9. The hanger 12 fixed on the outer surface of the swivel 11 rotates synchronously with the swivel 11.

The spiral blades on the outer side of the push rod 8 push the hanging jigs 20 hung on the unloading rod 6 to move one by one toward the material-stopping rod 14. When the hanging jigs 20 are pushed to the material-stopping rod 14, the hanging jigs 20 are separated from the spiral blades of the push rod 8 and slide downward. At this time, the material-stopping plate 15 at the upper end of the material-stopping rod 14 supports and positions it to keep it stable, and the hanging jigs 20 are hung by passing through the hanger 12 and engaging with the hanging rod 13 through the clearance groove 22; After the hanging is completed, the rotating ring 11 continues to rotate, driving the connected hanging jig 20 and the workpiece 21 to enter the electroplating tank 1. During the revolution, the hanging jig 20 rotates relative to the hanging rod 13, so that the workpiece 21 is always vertically downward to ensure that the surface can evenly contact the electroplating solution, thereby ensuring the electroplating effect.

[0025] Embodiment 2: This embodiment is disclosed on the basis of embodiment 1: the continuous feeding mechanism also includes: a material resistance rod 14, which is fixedly arranged at the upper end of one side of the electroplating tank 1, and the upper end of the material resistance rod 14 is opposite to the lower end of the discharge rod 6, and the upper end of the material resistance rod 14 is fixedly provided with a material resistance plate 15, the outer surface of the discharge box 4 is fixedly provided with a functional plate 16, and one end of the functional plate 16 is fixedly connected with a repulsion magnet 17, the upper surface of the end of the functional plate 16 connected to the discharge box 4 is fixedly provided with a switching motor 18, and one end of the output shaft of the switching motor 18 is fixedly connected with a switching gear 19, the outer surface of the hanging rod 13 is hung with a hanging jig 20, the lower end of the hanging jig 20 is engaged with a workpiece 21, the upper end side surface of the hanging jig 20 is provided with a clearance groove 22, and the upper end side surface of the hanging jig 20 is fixedly provided with a functional magnet 23, and the upper end side surface of the hanging jig 20 is fixedly provided with a discharge rod 24; The outer surfaces of the discharge rod 24 and the lower rod 6 are hung with a hanging fixture 20; The width of the end where the functional plate 16 is connected to the repelling magnet 17 is smaller than the width of the U-shaped opening of the hanger 12, the width of the repelling magnet 17 is smaller than the width of the U-shaped slot of the hanger 12, and the magnetic poles of the end facing the repelling magnet 17 and the functional magnet 23 are the same; The outer surface of the rotating ring 11 facing the switching gear 19 is evenly provided with tooth blocks, and the switching gear 19 is meshed and connected with the rotating ring 11 through the tooth blocks on the outer surface of the rotating ring 11; The upper end of the discharge rod 24 is a round rod with a plate-shaped protrusion on one side. The thickness of the plate-shaped protrusion on one side of the upper end of the discharge rod 24 is the same as the thickness of the clearance groove 22.

Under the action of the repulsive force and gravity, the hanging jig 20 drives the workpiece 21 to adjust to a vertical downward state, ensuring stable electroplating quality on the surface of the workpiece 21 during subsequent electroplating. The switching motor 18 is started, and the switching gear 19 on its output shaft meshes with the gear block on the outer surface of the rotating ring 11, which can control the rotation speed and angle of the rotating ring 11, and further accurately control the time and position of the suspended jig 20 and the workpiece 21 entering the electroplating tank 1, ensuring the accuracy and stability of the electroplating process; The hanging jig 20 revolves with the rotating ring 11 and rotates relative to the hanging rod 13.

At this time, the hanging jig 20 slides downward under the action of gravity and slides onto the conveyor belt 2 through the discharge rod 24. The baffles 3 on both sides of the conveyor belt 2 are at different heights, and the side close to the electroplating tank 1 is lower, which facilitates the smooth sliding of the hanging jig 20 and the workpiece 21, realizing automatic unloading and completing the cycle of the entire electroplating process.
