Description

Technical Field

[0001] This application relates to the field of rack galvanizing production technology, and in particular to an intelligent adaptive rack galvanizing rack and an automated rack galvanizing production line. Background Technology

[0002] With the rapid development of modern machinery manufacturing, the automotive industry, and the hardware accessories industry, the corrosion resistance and appearance quality of metal workpieces have become key indicators for measuring product quality. Electroplating, as a mature and efficient surface treatment method, is widely used in the processing of various metal products such as bolts, brackets, and connectors to impart excellent corrosion resistance and decorative properties. The intelligent adaptive plating rack and automated production line involved in this invention aim to provide a comprehensive solution for this process, capable of automatically and accurately transporting, firmly clamping, dynamically plating, and cyclically operating the workpiece, thereby meeting the urgent needs of modern industry for high-quality, high-efficiency, and intelligent production.

[0003] In existing technologies, common rack plating production equipment mostly uses standardized, specialized racks in conjunction with immersion plating tanks. This traditional method has a relatively simple structure and high technological maturity. For large-scale continuous production of standard parts with a single specification and simple structure, it can maintain a relatively stable production cycle, and the initial construction and maintenance costs are relatively low. By simply moving the cathode or mechanically agitating, the basic anti-corrosion coating requirements of ordinary workpieces can be met to a certain extent, playing a positive role in the traditional manufacturing model of few varieties and large batches.

[0004] However, facing the increasing demand for flexible manufacturing with diverse varieties and small batches, as well as the high-quality processing requirements for precision irregular parts, existing technologies have revealed significant shortcomings: First, traditional fixtures have poor versatility and cannot adaptively adjust the clamping distance when faced with workpieces of different sizes or shapes, causing companies to frequently stop to change fixtures or stock a large number of special jigs, which seriously restricts the efficiency of line changeover; Second, workpieces are mostly in a static or simple oscillating state in the plating tank. For complex workpieces with grooves or blind holes, the "electric line shielding" effect can easily cause dead corners or uneven thickness of the plating layer, and there is a lack of targeted spray assistance and angle adjustment mechanisms, resulting in insufficient contact of the plating solution; In addition, existing equipment generally lacks full-process automated integration of workpiece loading and unloading, and lacks targeted anti-corrosion protection design for key components such as motors and cables, resulting in high manual labor intensity, low plating solution utilization, and frequent equipment failures in harsh acid and alkaline environments, making it difficult to achieve long-term stable automated operation.

[0005] In response to the aforementioned technologies, an intelligent adaptive plating rack and an automated production line for rack-plating zinc are provided. Summary of the Invention

Wheel 15 is rotatably connected to driven wheel 17 via belt 16. A connecting frame 18 is fixedly connected to the lower side of driven wheel 17. A hydraulic rod 19 is fixedly connected inside the connecting frame 18. A connecting block 20 is fixedly connected to the output end of the hydraulic rod 19. First connecting plates 21 are rotatably connected to both sides of the connecting frame 18. Second connecting plates 22 are rotatably connected inside the two first connecting plates 21. Second connecting plates 22 are rotatably connected to both sides of the connecting block 20. A clamping plate 23 is fixedly connected to the side of the two first connecting plates 21 that are close to each other. The conveying assembly includes a trough 2. The trough 2 is fixedly connected to the upper middle side of the base plate 1. A controller 3 is fixedly connected to the front side of the trough 2. Conveying frames 4 are fixedly connected to both sides of the upper part of the base plate 1. Conveying frames 4 are fixedly connected to both sides of the upper part of the trough 2. Conveying rollers 5 are evenly distributed inside the conveying frames 4.

[0031] This intelligent adaptive plating rack and automated zinc plating production line uses controller 3 as the core control unit to coordinate the actions of various components, achieving fully automated operation of the workpiece from conveying, clamping, plating to unloading. The specific working process is as follows: First, the operator neatly places the workpiece to be plated on the conveyor roller 5 of the conveyor rack 4. After the controller 3 issues a start command, the conveyor roller 5 rotates synchronously under the drive mechanism. The friction between the roller and the bottom of the workpiece drives the workpiece to move smoothly, accurately conveying the workpiece to the preset clamping position directly above the tank 2. During the conveying process, the rotation speed of the conveyor roller 5 remains constant to ensure the continuity and positioning accuracy of the workpiece transfer. After the workpiece reaches the designated position, the conveying component sends a positioning signal to the controller 3, and the controller 3 then issues an instruction. The drive motor 7 on the upper side inside the support frame 6 starts, and the output shaft of the drive motor 7 drives the turntable 8 to rotate at a fixed speed. The first connecting frame 9 on the turntable 8 moves in a circular motion with the turntable 8, which in turn drives the first connecting rod 10 connected to it to swing eccentrically. The second connecting rod 11 at the top of the first connecting rod 10 then moves in a bending and stretching motion. Through the coordinated linkage of the two, the second connecting frame 12 and the carrier frame 13 connected to it are moved to be directly above the workpiece. At this time, the central axis of the carrier frame 13 is aligned with the center of the workpiece. Then, the controller 3 sends an angle adjustment signal to the rotating motor 14 on the lower side inside the carrier frame 13. The output end of the rotating motor 14 drives the drive wheel 15 to rotate. The drive wheel 15 transmits power to the driven wheel 17 through the belt 16, causing the driven wheel 17 to rotate. The connecting frame 18, which is fixedly connected to the driven wheel 17, rotates with the driven wheel 17, driving the clamping mechanism below to adjust its angle until the clamping surface of the clamping plate 23 is completely in contact with the outer surface of the workpiece, adapting to the shape and size of the workpiece. After the angle adjustment is completed, the hydraulic rod 19 inside the connecting frame 18 receives the clamping command from the controller 3. The piston rod of the hydraulic rod 19 extends downward, pushing the connecting block 20 at its output end to move vertically downward. The second connecting plate 22, which is rotatably connected to both sides of the connecting block 20, deflects at an angle as the connecting block 20 moves, thereby driving the first connecting plate 21, which is rotatably connected to it, to rotate inward around the connection point of the connecting frame 18. The clamping plate 23 on the side where the two first connecting plates 21 are close to each other moves towards the workpiece synchronously. When the clamping plate 23 contacts the surface of the workpiece... After contact, the hydraulic rod 19 continues to apply pressure to the preset pressure value. Once the controller 3 detects that the clamping force has reached the target value through the pressure sensor, it controls the hydraulic rod 19 to stop moving, thus completing the stable clamping of the workpiece. After the workpiece is fixed, the drive motor 7 starts again and runs in reverse. Through the linkage of the first connecting rod 10 and the second connecting rod 11, it drives the support frame 13 to move down, slowly sending the workpiece into the plating solution in the tank 2 until the workpiece is completely submerged in the plating solution. At this time, the controller 3 controls the drive motor 7 to stop running, maintaining the plating posture of the workpiece. During the plating process, the controller 3 intermittently sends rotation commands to the rotating motor 14. The rotating motor 14 drives the connecting frame 18 and the workpiece to rotate slowly at a low speed, so that all surfaces of the workpiece can be evenly contacted with the plating solution, avoiding uneven plating.Meanwhile, the plating solution in tank 2 maintains continuous circulation to ensure the stability of the plating solution composition on the workpiece surface. When the plating time reaches the preset value, controller 3 instructs drive motor 7 to rotate forward, which in turn moves the workpiece upward out of tank 2 via a linkage mechanism. After the workpiece is moved out, it stays for 10-20 seconds to allow excess plating solution to drip back into tank 2. Then, controller 3 instructs hydraulic rod 19 to retract, causing connecting block 20 to move upward and deflect second connecting plate 22, which in turn causes first connecting plate 21 to rotate outward. Clamping plate 23 separates from the workpiece, and the workpiece falls back onto conveyor roller 5 below after losing its clamping. Conveyor roller 5 rotates again to transport the plating completed workpiece to the unloading station, completing the plating process for a single workpiece.

[0032] refer to Figure 1 , Figure 2 and Figure 7 A liquid storage cylinder 37 is fixedly connected to the upper rear side of the base plate 1. A liquid extraction pipe 38 is fixedly connected to the upper side of the liquid storage cylinder 37. The liquid extraction pipe 38 is fixedly connected to the input end of the circulation pump 39. A liquid delivery pipe 40 is fixedly connected to the output end of the circulation pump 39. A diversion pipe 41 is fixedly connected to the top end of the liquid delivery pipe 40. A concentrator pipe 42 is fixedly connected to the top end of the diversion pipe 41. A circulation assembly is fixedly connected to the adjacent side of the two concentrator pipes 42. The circulation assembly is used to uniformly spray the plating solution onto the surface of the workpiece. The circulation assembly includes a nozzle 43. The nozzle 43 is fixedly connected to the adjacent side of the concentrator pipe 42. Fixing rings 44 are fixedly connected to both sides of the outer side of the two concentrator pipes 42. The fixing rings 44 are fixedly connected to both sides of the inner side of the tank body 2. A return pipe 45 is fixedly connected to the rear side of the tank body 2. The return pipe 45 is fixedly connected to the left side of the liquid storage cylinder 37.

[0033] Sufficient plating solution is stored in the reservoir 37 on the upper rear side of the base plate 1 to provide a stable source for the system and avoid frequent replenishment interruptions to production. The top suction pipe 38 introduces the plating solution into the input end of the circulation pump 39. After the circulation pump 39 starts, it acts as a power source to pressurize the plating solution, ensuring that sufficient plating solution reaches each nozzle 43. The plating solution is then delivered to the distribution pipe 41 via the output pipe 40. In scenarios where workpieces are processed simultaneously on both sides, the distribution pipe 41 evenly distributes the concentrated plating solution to the two concentrator pipes 42, avoiding imbalance in the supply to one side and ensuring consistent plating thickness on both sides. The concentrator pipes 42 are securely fixed inside the tank 2 by external fixing rings 44. The fixing rings 44 prevent plating solution impact from causing pipe displacement, ensuring the uniformity of the coating thickness of the nozzles 43. 3. The positioning is precise, and the central pipe 42 guides the plating solution to the connected nozzle 43. The nozzle 43 sprays the plating solution evenly onto the surface of the workpiece in the tank 2 in the form of atomization or columnar spray. Atomization spraying allows the plating solution to penetrate the gaps in the workpiece, while columnar spraying enhances the plating intensity in specific areas and increases the contact area to ensure that there are no dead corners in the plating. The plating solution dripping after spraying collects in the tank 2 and flows back to the storage tank 37 through the return pipe 45 on the back of the tank 2, forming a complete plating solution cycle. Recycling and reuse can reduce waste and lower production costs, while also reducing the environmental pressure of waste plating solution disposal. Through the closed-loop operation of "storage-transportation-spraying-return", the needs of continuous mass production and precision production are met, while taking into account cost control and environmental protection requirements.

[0034] refer to Figure 1 , Figure 2 and Figure 4 The driving wheel 15 and the driven wheel 17 are rotatably connected to the inside sides of the support frame 13; the circulating pump 39 is fixedly connected to the upper rear side of the base plate 1; the support frame 6 is set on the rear side of the conveyor frame 4, and the clamping assembly is set on the upper side of the conveyor roller 5; a wear-resistant conductive pad is fixedly connected to the inner side of the clamping plate 23, and the wear-resistant conductive pad is made of a composite material of copper alloy and polytetrafluoroethylene.

[0035] Both the driving pulley 15 and the driven pulley 17 are rotatably connected to the inner sides of the support frame 13 via bearings, allowing the two pulleys to rotate flexibly with stable coaxiality. This provides reliable support for the belt drive 16, reduces frictional resistance during pulley rotation, ensures efficient and stable power transmission, and prevents belt 16 slippage or wear due to pulley misalignment, thus extending the service life of the transmission components. The circulating pump 39 is firmly fixed to the upper rear side of the base plate 1 with bolts, arranged parallel to the liquid storage tank 37. This not only saves equipment space but also effectively reduces the vibration generated by the circulating pump 39 during operation thanks to the stable support of the base plate 1, preventing vibration from being transmitted to other components and affecting the overall operating accuracy of the equipment. It also facilitates daily inspection and maintenance of the circulating pump 39 by operators. The support frame 6 is vertically set on the rear side of the conveyor frame 4, and its bottom is welded to the base plate 1, serving as the drive motor for the upper part. The linkage mechanism 7 provides a solid installation foundation, while the clamping assembly is correspondingly set on the upper side of the conveying roller 5, maintaining precise alignment with the conveying path of the conveying roller 5. This ensures that after the conveying roller 5 delivers the workpiece to the designated station, the clamping assembly can quickly and accurately position and clamp the workpiece, achieving seamless connection between conveying and clamping actions. A wear-resistant conductive pad is fixedly connected to the inner side of the clamping plate 23 with high-strength adhesive. This wear-resistant conductive pad is made of a composite material of copper alloy and polytetrafluoroethylene. The copper alloy gives the pad excellent conductivity, ensuring that the current can be stably transmitted to the workpiece surface during the plating process, ensuring the uniformity and adhesion of the plating layer. The polytetrafluoroethylene provides excellent wear resistance and corrosion resistance, effectively resisting frictional wear and corrosion of the plating solution during workpiece clamping. At the same time, the fine texture of the pad surface can increase the friction with the workpiece, improve clamping stability, and prevent the workpiece from loosening or shifting during the plating process.

[0036] refer to Figure 1 , Figure 5 and Figure 6The tank 2 has a frame column 24 fixedly connected inside. A top suspension beam 25 is fixedly connected to the upper side of the frame column 24. Evenly distributed suspension hooks 26 are fixedly connected to the upper side of the top suspension beam 25. An adjustable clamp assembly 27 is fixedly connected inside the frame column 24. Evenly distributed motor cable interface fixing brackets 28 are provided on the upper side of the adjustable clamp assembly 27. A VK cover 29 is fixedly connected to the upper side of the motor cable interface fixing brackets 28. A base 30 is fixedly connected to the front side of the VK cover 29. The front side of the base 30... A connecting assembly is fixedly connected to facilitate the processing of the workpiece. The connecting assembly includes a lower wall side support 31, which is fixedly connected to the front side of the base 30. The lower wall side support 31 is rotatably connected to a first connecting rod 32, which is rotatably connected to a second connecting rod 33. The second connecting rod 33 is rotatably connected to a cable fixing bracket 34. A vertical plate 35 is fixedly connected to the lower side of the base 30. An electric push rod 36 is fixedly connected to the front side of the vertical plate 35. The output end of the electric push rod 36 is fixedly connected to the second connecting rod 33.

[0037] When using this device, the first step is to position the workpiece. For standardized workpieces produced in batches, they are directly suspended on the evenly distributed hanging hooks 26 below the top suspension beam 25. The frame column 24 and the top suspension beam 25 form a stable support structure, ensuring the stability of the workpiece position after being loaded. For irregularly shaped or non-standard sized workpieces, the clamping distance is adjusted using the adjustable clamp group 27 on the frame column 24 to clamp and fix the workpiece, eliminating the need for additional custom-made clamps. During equipment operation, protective measures are implemented simultaneously. The motor cables of the adjustable clamp group 27 are uniformly organized and fixed through the motor cable interface fixing bracket 28 to prevent tangled cables from affecting equipment operation. The VK cover 29 protects the interface area, effectively isolating dust and splashed plating solution in the workshop and preventing electrical interface damage. Corrosion or poor contact can cause damage, making it suitable for the humid and corrosive environment of the plating workshop. For the processing needs of precision parts or complex structure workpieces, the connecting component fixed on the base 30 on the front side of the VK cover 29 is activated. The electric push rod 36 fixed on the vertical plate 35 provides power to push the second link 33 to move. The second link 33 drives the first link 32 on the lower wall side support 31 to bend and extend, thereby driving the cable fixing bracket 34 and the clamped workpiece to adjust to the optimal plating angle. This ensures that all surfaces of the workpiece to be plated can fully contact the plating solution in the tank 2, eliminating dead corners in the plating solution. After the workpiece completes the plating operation, the hanging hook 26 or the adjustable clamp group 27 is released, and the workpiece falls back to the conveying system and is transferred to the next process. The whole process realizes the efficient connection of workpiece from positioning, plating to transfer, ensuring stable and orderly production.
