Description

Technical Field

[0001] This invention relates to the field of electroplating technology for automotive parts, specifically to a continuous selective plating device for automotive parts based on coaxial displacement. Background Technology

[0002] In the automotive manufacturing industry, electroplating of automotive parts is a key process to ensure their corrosion resistance, wear resistance and aesthetics. However, current traditional electroplating equipment for automotive parts has many insurmountable drawbacks in actual production, which seriously restricts the high efficiency and high quality development of automotive parts electroplating production.

[0003] From the perspective of production process, most traditional equipment adopts intermittent feeding, electroplating and unloading methods. In this way, the equipment needs to stop running in each work cycle to perform feeding and unloading operations, which affects the overall production progress of automobiles. In terms of equipment structure, traditional electroplating equipment has a complex structural design, often integrating multiple independent mechanical units and control systems. The daily operation process is cumbersome, and the complex structure also leads to a high equipment failure rate, causing production interruptions and further reducing production efficiency.

[0004] Specifically, regarding different types of traditional electroplating equipment, the common drum-type electroplating equipment, although capable of batch processing a certain number of parts, suffers from surface damage due to the limited internal space of the drum and its single movement mode, causing collisions and friction between parts. In actual production, parts processed by drum-type electroplating equipment are prone to surface scratches and wear, affecting product quality. Moreover, because the contact time and degree between parts at different positions inside the drum and the electroplating solution vary, it is impossible to guarantee that the electroplating time and electroplating effect of each part are consistent, resulting in inconsistent product quality.

[0005] While rack plating equipment can better control the electroplating process of individual parts, the excessive manual operation of loading and unloading not only consumes a lot of labor costs, but also makes it easy for human factors to cause operational errors, affecting production efficiency and product quality. If the parts are not hung in the correct position during manual loading, it will lead to uneven electroplating. If the operation is not timely during manual unloading, the parts will stay in the electroplating solution for too long or too short time, which will also affect the electroplating effect. Summary of the Invention

[0006] The purpose of this invention is to provide a continuous selective plating equipment for automotive parts based on coaxial displacement, in order to solve the problems mentioned in the background art, such as insufficient production capacity due to intermittent production, high procurement costs due to complex equipment structure, cumbersome operation, high failure rate, and the efficiency and quality defects of traditional drum-type and rack-type plating equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a continuous electroplating device for automotive parts based on coaxial displacement, comprising an electroplating tank, a conveyor belt on one side of the electroplating tank, and baffles on both sides of the conveyor belt. The baffles on both sides of the conveyor belt are at different heights, and the baffle closer to the electroplating tank is lower than the other baffle. A continuous feeding mechanism is provided at the upper end of the electroplating tank. The feeding, electroplating, and unloading processes are simultaneously realized by the coaxial rotation of the automotive parts and their rotation during the revolution. The continuous feeding mechanism is designed with its upper end tilted towards the conveyor belt.

[0008] The continuous feeding mechanism includes a feeding box, which is fixedly installed on the upper surface of one end of the electroplating tank. A guide plate is fixedly connected to the upper end of the electroplating tank on one side of the feeding box, and a feeding rod is fixedly connected to the lower end of the guide plate. A feeding motor is fixedly installed on the lower outer surface of the feeding box, and a rotating push rod is installed inside the lower end of the feeding box. A center block is fixedly installed on one outer surface of the feeding box, and a center slip ring is fixedly installed on the outer surface of the center block. A rotating ring is installed on the outer surface of the center slip ring, and a bracket is fixedly installed on the outer surface of the ring. A hanging rod is fixedly connected to one end of the bracket.

[0009] The continuous feeding mechanism further includes: a stop bar, which is fixedly installed on the upper side of the electroplating tank, with the upper end of the stop bar facing the lower end of the feeding bar, and a stop plate is fixedly installed on the upper end of the stop bar; a functional plate is fixedly installed on the outer surface of the feeding box, and a repulsive magnet is fixedly connected to one end of the functional plate; a switching motor is fixedly installed on the upper surface of the end of the functional plate connected to the feeding box, and a switching gear is fixedly connected to one end of the output shaft of the switching motor; a suspension fixture is hung on the outer surface of the hanging rod, and a workpiece is engaged at the lower end of the suspension fixture; a clearance groove is opened on the upper side surface of the suspension fixture, and a functional magnet is fixedly installed on the upper side surface of the suspension fixture; and a discharge bar is fixedly installed on the upper side of the electroplating tank facing the conveyor belt.

[0010] The outer surfaces of the discharge rod and the unloading rod are equipped with suspension fixtures.

[0011] Preferably, the directional plate is L-shaped, and one side surface of the directional plate is in contact with the outer surface of the feeding box, and the thickness of the directional plate is the same as the width of the relief groove.

[0012] By adopting the above technical solution, the suspended jig can be accurately positioned when it is hung on the unloading rod through the cooperation of the directional plate and the relief groove, which ensures the stability and accuracy of the suspended jig during subsequent movement and prevents it from shaking or deviating at will, thereby ensuring the smooth progress of the loading process.

[0013] Preferably, the outer surface of the push rod is fixedly provided with helical blades, and the rotating shaft of the push rod is fixedly connected to the output shaft of the feeding motor.

[0014] By adopting the above technical solution, when the feeding motor drives the push rod to rotate, the spiral blades can push the suspended jigs hanging on the feeding rod one by one and stably towards the abutment rod, realizing intermittent and orderly feeding operation, improving the efficiency and accuracy of feeding, and avoiding the chaotic situation of jamming or multiple suspended jigs being pushed at the same time during the feeding process.

[0015] Preferably, one end of the bracket is U-shaped, and the bracket is rotatably connected to the suspension fixture via a hanging rod. The diameter of the hanging rod is greater than the width of the relief groove, and the thickness of the bracket is the same as the width of the relief groove.

[0016] The above technical solution allows the U-shaped design to facilitate the hanging fixture to be engaged with the hanging rod through the relief groove, ensuring the reliability of the connection. The diameter of the hanging rod is larger than the width of the relief groove, which can prevent the hanging fixture from accidentally detaching from the hanging rod during its rotation, ensuring the stable progress of the electroplating process.

[0017] Preferably, the width of the end where the functional plate is connected to the repulsive magnet is less than the width of the U-shaped opening of the bracket, the width of the repulsive magnet is less than the width of the U-shaped groove of the bracket, and the magnetic poles of the repulsive magnet and the functional magnet are the same at opposite ends.

[0018] By adopting the above technical solution, the size design of the functional plate and the repulsive magnet allows them to be close to the suspension fixture without interfering with the normal operation of the bracket. The repulsive force generated by the repulsive magnet and the functional magnet having the same magnetic pole can adjust the suspension fixture to a vertically downward state after the suspension fixture is connected to the bracket, ensuring that the surface of the workpiece can be evenly contacted with the electroplating solution during the electroplating process and guaranteeing the electroplating quality.

[0019] Preferably, the outer surface of the rotating ring opposite the switching gear is uniformly provided with tooth blocks, and the switching gear is connected to the rotating ring through the tooth blocks on the outer surface of the rotating ring.

[0020] By adopting the above technical solution, when the switching gear driven by the switching motor rotates, the rotation speed and angle of the rotating ring can be precisely controlled by meshing with the outer tooth block of the rotating ring. This allows for precise control of 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.

[0021] Preferably, the upper end of the discharge rod is 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 discharge rod is the same as the thickness of the relief groove, and the lower end of the discharge rod is located above the conveyor belt between the two baffles.

[0022] Using the above technical solution, the plate-shaped protrusion at the upper end of the discharge rod cooperates with the relief groove. When the suspended jig rotates with the rotating ring to the position of the discharge rod, it guides the suspended jig 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 sliding of the suspended jig and the workpiece onto the conveyor belt, realizes automatic unloading, and improves the degree of automation and production efficiency.

[0023] Preferably, the suspension fixture hanging on the outer surface of the feeding rod is inverted, and the suspension fixture hanging on the outer surface of the feeding rod is engaged with the spiral blades on the outer surface of the push rod, and the outer surface of the suspension fixture hanging on the outer surface of the feeding rod is in contact with the inner surface of the feeding box.

[0024] By adopting the above technical solution, the inverted suspension fixture is easy 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 feeding box can prevent the suspension fixture from shaking during movement. The engaging installation with the spiral blades of the push rod ensures that the suspension fixture can be pushed stably when the push rod rotates, thus providing a guarantee for continuous and efficient feeding.

[0025] Compared with the prior art, the beneficial effects of the present invention are: the continuous selective plating equipment for automotive parts based on coaxial displacement:

[0026] 1. By intermittently rotating the feeding box in conjunction with the push rod, the suspended fixture and workpiece hanging on the feeding rod can be pushed one by one towards the abutment rod. The abutment rod and abutment plate are used to position the suspended fixture, so that the suspended fixture can be connected to the hanger that revolves with the rotating ring. This allows the suspended fixture and workpiece to enter the electroplating tank for electroplating during the rotation of the rotating ring. The feeding process does not require complicated operations, thus improving processing efficiency.

[0027] 2. By adjusting the angle of the suspension fixture after it slides into place using repulsive magnets and functional magnets, the workpiece can remain vertically downward under the push of repulsive force and gravity after loading, so as to ensure the stability of the electroplating quality of the workpiece surface during the subsequent electroplating process.

[0028] Furthermore, by utilizing the method of the suspended jig rotating relative to the hanging rod during the revolution of the rotating ring, the suspended jig can slide down autonomously through the discharge rod under neutral force when it is moved to the discharge rod. With the help of the conveyor belt, the purpose of automatic material unloading is achieved. At the same time, the setting of the clearance groove ensures that the suspended jig cannot detach from the hanging rod when it rotates to the position, thus ensuring the stability of the electroplating process.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-8 The present invention provides a technical solution: a continuous selective plating equipment for automotive parts based on coaxial displacement.

[0040] Example 1: This example discloses: an electroplating tank 1, a conveyor belt 2 on one side of the electroplating tank 1, and baffles 3 on both sides of the conveyor belt 2. The baffles 3 on both sides of the conveyor belt 2 are at different heights, and the baffle 3 on the side closer to the electroplating tank 1 is lower than the other baffle 3. A continuous feeding mechanism is provided at the upper end of the electroplating tank 1. The feeding, electroplating and unloading processes are realized simultaneously by the coaxial rotation of the automotive parts and their rotation during the revolution. The continuous feeding mechanism is designed with the upper end tilted towards the conveyor belt 2.

[0041] The continuous feeding mechanism includes a feeding box 4, which is fixedly installed on the upper surface of one end of the electroplating tank 1. A guide plate 5 is fixedly connected to the upper end of the electroplating tank 1 on one side of the feeding box 4, and a feeding rod 6 is fixedly connected to the lower end of the guide plate 5. A feeding motor 7 is fixedly installed on the lower outer surface of the feeding box 4, and a rotating push rod 8 is installed inside the lower end of the feeding box 4. A center block 9 is fixedly installed on one outer surface of the feeding box 4, and a center slip ring 10 is fixedly installed on the outer surface of the center block 9. A rotating ring 11 is installed on the outer surface of the center slip ring 10, and a bracket 12 is fixedly installed on the outer surface of the ring 11. A hanging rod 13 is fixedly connected to one end of the bracket 12.

[0042] The directional plate 5 is L-shaped, and one side surface of the directional plate 5 is in contact with the outer surface of the feeding box 4. The thickness of the directional plate 5 is the same as the width of the relief groove 22.

[0043] Spiral blades are fixedly provided on the outer surface of the push rod 8, and the rotating shaft of the push rod 8 is fixedly connected to the output shaft of the feeding motor 7.

[0044] One end of the bracket 12 is designed in a U-shape, and the bracket 12 is rotatably connected to the suspension fixture 20 through the hanging rod 13. The diameter of the hanging rod 13 is greater than the width of the relief groove 22, and the thickness of the bracket 12 is the same as the width of the relief groove 22.

[0045] Before starting the equipment, install the automotive parts to be electroplated on the suspension fixture 20. The suspension fixture 20 is engaged with the directional plate 5 and the feeding rod 6 through the relief groove 22 and hung upside down on the feeding rod 6. As gravity drives the suspension fixture 20 to slide down the feeding rod 6 until the outer surface of the suspension fixture 20 is in contact with the inner surface of the feeding box 4 and one end of the suspension fixture 20 is engaged with the spiral blade of the push rod 8.

[0046] The rotating ring 11 is installed on the outer surface of the central slip ring 10 and can rotate around the central block 9. The bracket 12 fixed on the outer surface of the rotating ring 11 rotates synchronously with the rotating ring 11. When the rotating ring 11 rotates, the bracket 12 moves to the docking position with the suspension fixture 20, that is, the two ends of the bracket 12 are respectively facing the unloading rod 6 and the abutment rod 14.

[0047] When the feeding motor 7 is started, its output shaft drives the push rod 8 to rotate. The spiral blades on the outside of the push rod 8 push the suspension fixtures 20 hanging on the feeding rod 6 to move one by one toward the abutment rod 14. When the suspension fixtures 20 are pushed to the abutment rod 14, the suspension fixtures 20 disengage from the spiral blades of the push rod 8 and slide downward. At this time, the abutment plate 15 at the upper end of the abutment rod 14 supports and positions it to keep it stable, while the suspension fixtures 20 pass through the relief groove 22 to engage with the hanging rod 13 and hang.

[0048] After the installation is completed, the rotating ring 11 continues to rotate, driving the connected suspension fixture 20 and workpiece 21 into the electroplating tank 1. During the revolution, the suspension fixture 20 rotates relative to the hanging rod 13, so that the workpiece 21 is always vertically downward to ensure that the surface can be evenly contacted with the electroplating solution and to ensure the electroplating effect.

[0049] Example 2: This example discloses the continuous feeding mechanism based on Example 1: The continuous feeding mechanism further includes: a stop rod 14, which is fixedly installed on the upper side of the electroplating tank 1, with the upper end of the stop rod 14 facing the lower end of the feeding rod 6, and a stop plate 15 is fixedly installed on the upper end of the stop rod 14; a functional plate 16 is fixedly installed on the outer surface of the feeding box 4, and a repulsive magnet 17 is fixedly connected to one end of the functional plate 16; a switching motor 18 is fixedly installed on the upper surface of the end of the functional plate 16 connected to the feeding box 4, and a switching gear 19 is fixedly connected to one end of the output shaft of the switching motor 18; a suspension fixture 20 is hung on the outer surface of the hanging rod 13; a workpiece 21 is engaged at the lower end of the suspension fixture 20; a clearance groove 22 is opened on the upper side surface of the suspension fixture 20, and a functional magnet 23 is fixedly installed on the upper side surface of the suspension fixture 20; and a discharge rod 24 is fixedly installed on the upper side of the electroplating tank 1 facing the conveyor belt 2.

[0050] Suspension fixtures 20 are mounted on the outer surfaces of the discharge rod 24 and the unloading rod 6;

[0051] The width of the end where the functional plate 16 is connected to the repulsive magnet 17 is less than the width of the U-shaped opening of the bracket 12, the width of the repulsive magnet 17 is less than the width of the U-shaped groove of the bracket 12, and the magnetic poles of the repulsive magnet 17 and the functional magnet 23 are the same at the opposite ends.

[0052] The outer surface of the rotating ring 11 opposite the switching gear 19 is evenly provided with tooth blocks, and the switching gear 19 is meshed with the rotating ring 11 through the tooth blocks on the outer surface of the rotating ring 11.

[0053] The upper end of the discharge rod 24 is 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 discharge rod 24 is the same as the thickness of the relief groove 22. The lower end of the discharge rod 24 is located above the conveyor belt 2 between the two baffles 3.

[0054] The suspension fixture 20 hanging on the outer surface of the feeding rod 6 is inverted, and the suspension fixture 20 hanging on the outer surface of the feeding rod 6 is engaged with the spiral blade on the outer surface of the push rod 8. The outer surface of the suspension fixture 20 hanging on the outer surface of the feeding rod 6 is in contact with the inner surface of the feeding box 4.

[0055] When the suspension fixture 20 is pushed to the abutment rod 14 and connected to the hanger 12, the repulsion magnet 17 on the functional plate 16 and the functional magnet 23 on the suspension fixture 20 play their roles. Since the magnetic poles of the two are the same at opposite ends, a repulsive force is generated, which causes the suspension fixture 20 to drive the workpiece 21 to adjust to a vertically downward state under the action of the repulsive force and gravity, so as to ensure the stability of the electroplating quality of the workpiece 21 surface during subsequent electroplating.

[0056] When the switching motor 18 starts, the switching gear 19 on its output shaft meshes with the tooth 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 precisely control the time and position of the suspended jig 20 and the workpiece 21 entering the electroplating tank 1, so as to ensure the accuracy and stability of the electroplating process.

[0057] The suspended fixture 20 revolves around the rotating ring 11 and rotates relative to the hanging rod 13. When it moves to the position of the discharge rod 24, the plate-shaped protrusion on one side of the upper end of the discharge rod 24 cooperates with the relief groove 22 of the suspended fixture 20. At this time, the suspended fixture 20 slides down under the action of gravity and slides down 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, with the side closer to the electroplating tank 1 being lower, which facilitates the smooth sliding of the suspended fixture 20 and the workpiece 21, realizing automatic unloading and completing the cycle of the entire electroplating process.

[0058] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the protection scope of the present invention.
