Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a wheelchair frame surface corrosion-resistant processing device suitable for wheelchair processing. Background Art

[0002] As society improves its care for the disabled and the elderly, the market demand for wheelchairs, as an important auxiliary mobility tool, continues to grow. At the same time, the use environment of wheelchairs is complex and diverse, including indoor, outdoor, wet, dry and other different scenarios, which puts higher requirements on the surface corrosion resistance of wheelchair frames. Traditional wheelchair frame surface treatment processes often have many problems and are difficult to meet the modern market's expectations for high quality and long life of wheelchairs. There is an urgent need for an innovative and efficient surface corrosion resistance treatment equipment and process to improve the quality and durability of wheelchairs.

[0003] In the past, the surface treatment process of wheelchair frames was relatively scattered and inefficient. For example, surface polishing mostly uses manual grinding or simple mechanical polishing, which is not only labor-intensive and inefficient, but also difficult to ensure the uniformity and smoothness of polishing, and easily leaves scratches, pits and other defects on the surface of the frame, affecting the subsequent treatment effect and product appearance. During the activation treatment process, the use and control of chemical solvents are not precise enough to fully remove the surface oxide film and effectively improve the surface activity, resulting in insufficient bonding between the subsequent coating and the substrate. The electroplating process usually adopts a fixed electrode spacing method, which is difficult to adapt to the needs of wheelchair frames of different specifications, resulting in uneven thickness of the electroplating layer and frequent local corrosion problems, which seriously reduces the corrosion resistance and quality stability of the product. Air drying treatment also relies on natural drying or simple ventilation equipment, which has a slow drying speed and is easily contaminated by external dust and impurities, affecting the surface quality of the product. At the same time, it prolongs the production cycle, increases production costs, and limits the production efficiency and market competitiveness of the enterprise.

[0018] Compared with the prior art, it has the following beneficial effects:

[0019] 1. In the present invention, the bottom ends of four limit slide bars are respectively slidably connected inside four limit slide holes. This design greatly enhances the stability of the control frame during the lifting process. When the servo electric cylinder drives the control frame to move up and down, the cooperation between the limit slide bars and the limit slide holes effectively limits the shaking and deviation of the control frame, ensuring the accuracy and stability of its motion trajectory, which is not only crucial for the smooth operation of the control frame itself, but also directly affects the position accuracy of the wheelchair frame during the processing process, because the wheelchair frame is placed under the control frame for subsequent operations. A stable control frame can avoid unnecessary displacement of the wheelchair frame during the lifting process, thereby ensuring that each processing process can accurately act on the predetermined position of the wheelchair frame, reducing uneven processing effects or quality problems caused by position deviations, and improving the reliability of the entire processing process and the consistency of the product.

[0020] 2. When facing wheelchair frames of different specifications and sizes, the first electric slide can quickly adjust the distance between the two positioning frames to adapt to wheelchair frames of various widths, and the electric control rotator can flip the positioning frame to a suitable angle to facilitate accurate insertion of the wheelchair frame. This flexible adjustment method greatly improves the compatibility of the feeding unit with different wheelchair frames, reduces the time for equipment adjustment and changeover, and improves production efficiency. At the same time, it also ensures the stability of the wheelchair frame during feeding and processing, avoids displacement and shaking caused by loose clamping, and ensures the uniformity and quality stability of the surface corrosion resistance treatment;

[0021] When the two sides of the wheelchair frame are inserted into the positioning grooves, the positioning clamps can tightly clamp the wheelchair frame from both sides to ensure that it will not move in all directions. This precise positioning effect is crucial for the subsequent surface treatment process. During the surface polishing, activation, electroplating and other processes, the stable position of the wheelchair frame can ensure that the treatment process acts evenly on the surface of the frame, avoiding uneven treatment caused by frame shaking, improving the quality and effect of surface corrosion resistance treatment, ensuring that each wheelchair frame can meet the expected quality standards, and improving the product's qualification rate and reliability.

[0022] 3. By setting a polishing chamber on the far left side of the connecting groove and sending the wheelchair frame as a whole into the vibration polishing container, the polishing medium and polishing liquid inside the vibration polishing container are used to generate vibration in cooperation with the vibration polishing machine set at the bottom of the vibration polishing container, so that the polishing medium and polishing liquid can fully contact the surface of the wheelchair frame, thereby quickly completing the polishing process on the surface of the wheelchair frame. Compared with traditional manual or single mechanical polishing, the efficiency is greatly improved, surface defects and oxide layers can be quickly removed, a good basic surface state is provided for subsequent processing, and the overall processing effect and product quality are improved.

[0023] 4. When electroplating the surface of the wheelchair frame, the distance between the electrode plates on both sides is adjusted according to the specifications of the wheelchair frame. The second electric slides on both sides are used to control the two adjustment frames to adjust their positions inside the electroplating container. The spacing between the two electrode plates is accurately adjusted to ensure the stability of the plasma discharge intensity and the treatment effect, so that the electroplating layer can be evenly and densely deposited on the surface of the wheelchair frame. Compared with the electroplating method with a fixed electrode spacing, this adjustable design can better adapt to wheelchair frames of different shapes and sizes, improve the quality and consistency of electroplating, reduce problems such as uneven coating thickness and local corrosion caused by inappropriate electrode spacing, further improve the corrosion resistance of the wheelchair frame, ensure the quality stability of the product, reduce the scrap rate, and improve production efficiency, thereby improving the corrosion resistance treatment effect on the surface of the wheelchair frame.

[0024] Other features and advantages of the present invention will be set forth in the following description, and in part will become apparent from the description, or may be understood through implementation of the present invention.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] See also Figures 1 to 8 As shown, the wheelchair frame surface corrosion resistant treatment equipment suitable for wheelchair processing includes:

[0037] A processing rack 1, a material discharging rack 2 is fixedly arranged on the left and right sides of the processing rack 1 by a bolt group, a wheelchair frame to be processed is placed on the material discharging rack 2 on the left side, and the wheelchair frame is automatically fed with the feeding structure, and the surface corrosion resistance treatment is performed inside the processing rack 1, and finally the wheelchair frame after processing is placed on the top of the material discharging rack 2 on the right side;

[0038] Feeding unit 3, servo electric cylinders 5 are fixedly arranged around the inside of the processing frame 1, and the top ends of the driving shafts of the four servo electric cylinders 5 are fixedly arranged with feeding units 3, and the wheelchair frame is automatically fed and processed and regulated by the feeding unit 3, without manual operation, which reduces the labor intensity to a certain extent, and can also effectively improve the efficiency of corrosion-resistant treatment of the surface of the wheelchair frame;

[0039] The processing unit 4 is provided with a connecting groove 21 inside the processing frame 1, and the processing unit 4 is provided inside the connecting groove 21. Through the cooperation between the processing unit 4 and the feeding unit 3, the wheelchair frame is placed in a relatively closed space to complete continuous surface polishing, activation, electroplating and air-drying treatment, thereby greatly improving the corrosion resistance treatment effect on the surface of the wheelchair frame.

[0040] It should be noted that the discharge racks 2 fixed by bolt groups on both sides of the processing rack 1 in the present invention have constructed an efficient and convenient material flow system. In the production process, the operator only needs to place the wheelchair frame to be processed on the left discharge rack 2, and the subsequent feeding structure will be started, automatically and accurately feeding the wheelchair frame into the processing rack 1 for surface corrosion resistance treatment, and after the treatment is completed, it will be placed on the top of the right discharge rack 2. This automated process greatly reduces the links of direct manual contact with materials and reduces the labor intensity. At the same time, it avoids problems such as scratches and bumps on the surface of the wheelchair frame caused by improper manual handling, thereby ensuring the appearance quality of the product. Moreover, compared with the traditional manual feeding method, the efficiency of automated feeding is greatly improved, which can increase the production efficiency by about 30%-40%, saving a lot of time costs for the enterprise, improving the overall production efficiency, and enhancing the competitiveness of the enterprise in the market.

[0041] In addition, the servo electric cylinder 5 fixed around the inside of the processing frame 1 and the feeding unit 3 driven by it bring high precision and high stability to the processing process of the wheelchair frame. The servo electric cylinder 5 can accurately control the position and movement of the feeding unit 3 by virtue of its excellent positioning accuracy. When the wheelchair frame is automatically loaded, the feeding unit 3 can accurately place the wheelchair frame at the starting position of the processing unit 4, ensuring that each wheelchair frame is in the best state at the initial stage of entering the processing flow. During the entire processing process, the feeding unit 3 can also accurately adjust the position of the wheelchair frame according to the preset program, so that it can pass through each processing station in turn. This high-precision feeding and control mechanism effectively ensures that each wheelchair frame can obtain uniform and consistent surface corrosion-resistant treatment, avoids the situation where some areas are not properly processed or over-processed due to inaccurate feeding, greatly improves the quality stability and qualified rate of the product, reduces the generation of waste, thereby reducing production costs and improving the economic benefits of the enterprise;

[0042] Finally, the processing unit 4 set in the connecting groove 21 inside the processing frame 1 cooperates closely with the feeding unit 3 to jointly create a relatively closed processing space, which plays a key role in the surface corrosion resistance treatment effect of the wheelchair frame. In this closed space, the wheelchair frame can continuously complete a series of processes such as surface polishing, activation, electroplating and air-drying. First, the surface polishing is carried out in a stable environment to ensure the uniformity and smoothness of the polishing, remove minor surface defects and oxide layers, and provide a good foundation for subsequent activation and electroplating treatments. During the activation process, the precisely controlled chemical atmosphere can fully activate the surface of the wheelchair frame and enhance its bonding with the electroplating layer. During electroplating, the confined space helps to maintain the stability of the composition of the plating solution and the uniform distribution of current, so that the formed electroplating layer is denser and more uniform, which significantly improves the corrosion resistance. Finally, air drying is carried out in the same confined space to avoid the contamination of the treated surface by external dust, impurities, etc., thereby ensuring the surface quality of the product. Through this continuous and integrated treatment method, the surface corrosion resistance of the wheelchair frame can be improved by about 40%-50% compared with the traditional dispersed treatment process, which greatly extends the service life of the wheelchair and provides wheelchair users with more reliable products. At the same time, it also enhances the company's technical strength and brand image in the field of wheelchair manufacturing and enhances the market competitiveness of the product.

[0043] Embodiment 2:

[0044] Specifically, the feeding unit 3 includes a control frame 6, which is movably arranged directly above the processing frame 1, and the four sides of the bottom of the control frame 6 are respectively fixedly connected to the top of the driving shaft of the four servo electric cylinders 5. Four limit slide bars 7 are also fixedly arranged at the bottom of the control frame 6. Limit slide holes 8 are arranged inside the processing frame 1 and directly below the four limit slide bars 7, and the bottom ends of the four limit slide bars 7 are respectively slidably connected to the inside of the four limit slide holes 8; the bottom ends of the four limit slide bars 7 are respectively slidably connected to the inside of the four limit slide holes 8, thereby further ensuring the stability of the control frame 6 during the lifting control process, and also ensuring the stability of the wheelchair frame when adjusting its position at the bottom of the control frame 6.

[0045] Further, a first linear slide 9 is fixedly provided at the bottom of the control frame 6, and two first servo electric cylinders 10 are slidably provided at the bottom of the first linear slide 9, a lifting frame 11 is fixedly provided at the bottom ends of the driving shafts of the two first servo electric cylinders 10, and a second linear slide 12 is fixedly provided inside the lifting frame 11, a second servo electric cylinder 13 is slidably provided at the bottom of the second linear slide 12, and a connecting frame 14 is fixedly provided at the bottom end of the driving shaft of the second servo electric cylinder 13;

[0046] In addition, the driving end of the second servo electric cylinder 13 can also be fixedly provided with a rotating fixed frame 42, and the bottom of the rotating fixed frame 42 is rotatably provided with a connecting frame 14, wherein a rotating motor is fixedly provided inside the rotating fixed frame 42, and the bottom end of the output shaft of the rotating motor is fixedly connected to the inside of the connecting frame 14. When the surface of the wheelchair frame is subjected to corrosion-resistant treatment, the connecting frame 14 is controlled to rotate by the rotating fixed frame 42, thereby driving the wheelchair frame to rotate, which can further improve the corrosion-resistant treatment effect on the surface of the wheelchair frame.

[0047] First electric slides 15 are fixedly provided around the bottom of the connecting frame 14, and two opposite first electric slides 15 form a group, and electric-controlled rotators 16 are slidably provided on the opposite sides of the two first electric slides 15 in a group, and a rotating shaft 17 is rotatably provided between the opposite sides of the two electric-controlled rotators 16, a positioning frame 18 is fixedly provided on one side of the rotating shaft 17, and a plurality of positioning grooves 19 are provided on one side of the positioning frame 18, and positioning clamps 20 are slidably provided on both sides inside the positioning grooves 19, and the two positioning clamps 20 are slidingly driven by micro-electric cylinders arranged inside the positioning frame 18.

[0048] It should be noted that, in the process of performing corrosion-resistant treatment on the surface of the wheelchair frame, the lifting frame 11 is driven by the first linear slide 9 to slide to the leftmost side of the bottom of the control frame 6, and the second linear slide 12 is used to control the connecting frame 14 to slide to the top of the left unloading frame 2. At this time, the electric control rotator 16 inside the connecting frame 14 controls the rotating shaft 17 to flip 90 degrees, so that the positioning frames 18 on one side of the two rotating shafts 17 are in a vertical state. At this time, the driving end of the second servo electric cylinder 13 is used to control the connecting frame 14 to move downward. According to the specifications of the wheelchair frame, two sets of first electric slides 15 are used to control the two rotating shafts 17 to approach the two sides of the wheelchair frame. Then, the two sides of the wheelchair frame are inserted into the positioning grooves 19 inside the positioning frames 18 on both sides, and the wheelchair frame is clamped and positioned by the two positioning clamps 20 inside the positioning grooves 19. The clamping and positioning of the positioning frames 18 on both sides and the clamping and positioning of the upper and lower positioning clamps 20 can ensure the stability of the wheelchair frame during feeding and processing to the greatest extent.

[0049] The lifting frame 11 is driven to slide to the top of the connecting groove 21 by the first linear slide rail 9, and the lifting frame 11 is controlled to move downward by the two first servo electric cylinders 10 until the four sides of the lifting frame 11 and the four sides of the inner wall of the connecting groove 21 are sealed and connected. Sealing rings are sleeved around the lifting frame 11 to ensure the sealing of the connection between the lifting frame 11 and the connecting groove 21, so that the processing process of the wheelchair frame is all inside the connecting groove 21, effectively avoiding the adverse effects of external factors on the corrosion-resistant treatment of the wheelchair frame surface.

[0050] In a specific embodiment, the present invention utilizes the bottom ends of four limit slide bars 7 to be slidably connected inside four limit slide holes 8, respectively. This design greatly enhances the stability of the control frame 6 during the lifting process. When the servo electric cylinder 5 drives the control frame 6 to move up and down, the cooperation between the limit slide bars 7 and the limit slide holes 8 effectively limits the shaking and deviation of the control frame 6, ensuring the accuracy and stability of its motion trajectory, which is not only crucial for the smooth operation of the control frame 6 itself, but also directly affects the position accuracy of the wheelchair frame during the processing process, because the wheelchair frame is placed under the control frame 6 for subsequent operations. The stable control frame 6 can avoid unnecessary displacement of the wheelchair frame during the lifting process, thereby ensuring that each processing step can accurately act on the predetermined position of the wheelchair frame, reducing uneven processing effects or quality problems caused by position deviation, and improving the reliability of the entire processing process and the consistency of the product.

[0051] When it is necessary to grab the wheelchair frame from the left unloading rack 2, the first linear slide rail 9 can quickly and smoothly move the lifting frame 11 to the appropriate position, making the subsequent grabbing action more accurate and efficient. This flexible horizontal movement function, in conjunction with the coordinated work of other components, realizes the accurate grabbing of wheelchair frames at different positions, improves the versatility and adaptability of the feeding unit 3, reduces the strict requirements of the equipment on the placement of the wheelchair frame, provides convenience for the optimization of the production process, and improves the automation level and production efficiency of the entire production line; at the same time, in the process of grabbing the wheelchair frame, the second servo electric cylinder 13 can accurately control the descending height of the connecting frame 14 according to the height of the wheelchair frame, ensure that the positioning frame 18 can accurately align with the two sides of the wheelchair frame, and realize accurate grabbing action, while the second linear slide rail 12 ensures the stability of the connecting frame 14 during the vertical lifting process, avoiding grabbing failure or damage to the wheelchair frame due to shaking. This precise vertical positioning capability not only improves the working efficiency of the feeding unit 3, but also reduces the scrap rate and improves product quality, which is of great significance for the high-quality completion of the corrosion-resistant treatment on the surface of the wheelchair frame;

[0052] When facing wheelchair frames of different specifications and sizes, the first electric slide 15 can quickly adjust the distance between the two positioning frames 18 so that it can adapt to wheelchair frames of various widths, and the electric control rotator 16 can flip the positioning frame 18 to a suitable angle, which is convenient for accurate insertion of the wheelchair frame. This flexible adjustment method greatly improves the compatibility of the feeding unit 3 with different wheelchair frames, reduces the time for equipment adjustment and changeover, and improves production efficiency. At the same time, it also ensures the stability of the wheelchair frame during feeding and processing, avoids displacement and shaking caused by loose clamping, and ensures the uniformity and quality stability of the surface corrosion resistance treatment;

[0053] When the two sides of the wheelchair frame are inserted into the positioning grooves 19, the positioning clamps 20 can tightly clamp the wheelchair frame from both sides to ensure that it will not move in all directions. This precise positioning effect is crucial for the subsequent surface treatment process. During the surface polishing, activation, electroplating and other processes, the stable position of the wheelchair frame can ensure that the treatment process acts evenly on the surface of the frame, avoiding uneven treatment caused by frame shaking, improving the quality and effect of surface corrosion resistance treatment, ensuring that each wheelchair frame can meet the expected quality standards, and improving the product's qualification rate and reliability.

[0054] Embodiment 3:

[0055] Specifically, the processing unit 4 includes a polishing chamber 23, an activation chamber 24, an electroplating chamber 25 and an air-drying chamber 26. The interior of the connecting groove 21 is provided with three movable partitions 22 that can be moved up and down by an electric push rod, and the interior of the connecting groove 21 is divided into the polishing chamber 23, the activation chamber 24, the electroplating chamber 25 and the air-drying chamber 26 by the three movable partitions 22. A vibration polisher 28 is fixedly provided below the interior of the polishing chamber 23, and a vibration polishing container 27 is also movably provided inside the polishing chamber 23. The vibration polisher The driving end of 28 is fixedly connected to the bottom of the vibration polishing container 27, and a polishing medium feed port 29 and a polishing liquid feed port 30 are fixedly arranged at the upper part of the vibration polishing container 27, and a sorting discharge port 31 is also fixedly arranged at the lower part of the vibration polishing container 27, wherein one side of the polishing medium feed port 29, the polishing liquid feed port 30 and the sorting discharge port 31 are all extended to the outside of the processing frame 1, and a sorting filter is arranged inside the sorting discharge port 31, and a polishing medium outlet is arranged at the bottom of the sorting discharge port 31;

[0056] By setting a polishing chamber 23 at the leftmost side of the connecting groove 21, and by sending the entire wheelchair frame into the interior of the vibration polishing container 27, the polishing medium and polishing liquid in the vibration polishing container 27 are used to cooperate with the vibration polishing machine 28 set at the bottom of the vibration polishing container 27 to generate vibration, so that the polishing medium and polishing liquid can fully contact the surface of the wheelchair frame, and then the polishing treatment of the wheelchair frame surface is quickly completed. Compared with traditional manual or single mechanical polishing, the efficiency is greatly improved, and surface defects and oxide layers can be quickly removed, providing a good basic surface state for subsequent treatment, improving the overall treatment effect and product quality, and then the movable partition 22 on one side of the polishing chamber 23 is controlled to descend, and the wheelchair frame after the surface polishing treatment is immediately sent into the activation chamber 24 for the next treatment process.

[0057] An activation etch container 32 is fixedly disposed inside the activation chamber 24, and an activation solvent feed port and an activation solvent discharge port are disposed at the upper and lower parts of the activation etch container 32, respectively.

[0058] A chemical solvent is introduced into the interior of the activation etching container 32 through the activation solvent feed port, and the entire wheelchair frame is immersed in the chemical solvent to remove the oxide film on the surface of the wheelchair frame and increase the surface activity, thereby improving the bonding strength between the coating and the wheelchair frame surface during the subsequent electrode corrosion resistance treatment of the wheelchair frame surface.

[0059] An electroplating container 33 is fixedly installed inside the electroplating chamber 25, and adjustable electrode assemblies 34 are symmetrically arranged on both sides of the inside of the electroplating container 33; electroplating liquid feed ports and electroplating liquid discharge ports are also arranged at the upper and lower parts of the inside of the electroplating container 33.

[0060] Furthermore, the adjustable electrode assembly 34 includes an adjustment frame 36, and second electric slides 35 are fixedly arranged on both sides of the inner wall of the electroplating container 33, and an adjustment frame 36 is slidably arranged between the two opposite sides of the second electric slides 35, and a material clamping groove 37 is arranged inside the adjustment frame 36, and an electrode clamping plate 39 is movably arranged inside the material clamping groove 37, and two adjustment bolts 38 are threadedly arranged on one side of the material clamping groove 37, and one end of the two adjustment bolts 38 is rotatably connected to one side of the electrode clamping plate 39;

[0061] When the surface of the wheelchair frame is electroplated, the distance between the electrode plates on both sides is adjusted according to the specifications of the wheelchair frame. The second electric slides 35 on both sides are used to control the two adjustment frames 36 to adjust their positions inside the electroplating container 33. The spacing between the two electrode plates is precisely adjusted to ensure the stability of the plasma discharge intensity and the treatment effect, so that the electroplating layer can be evenly and densely deposited on the surface of the wheelchair frame. Compared with the electroplating method with a fixed electrode spacing, this adjustable design can better adapt to wheelchair frames of different shapes and sizes, improve the quality and consistency of electroplating, reduce problems such as uneven coating thickness and local corrosion caused by inappropriate electrode spacing, further improve the corrosion resistance of the wheelchair frame, ensure the quality stability of the product, reduce the scrap rate, and improve production efficiency, thereby improving the corrosion resistance treatment effect of the wheelchair frame surface.

[0063] Embodiment 4:

[0064] Specifically, this embodiment also discloses a treatment method for a wheelchair frame surface corrosion-resistant treatment device suitable for wheelchair processing, comprising the following steps:

[0065] Step 1: During the corrosion-resistant treatment of the wheelchair frame surface, the lifting frame 11 is driven by the first linear slide 9 to slide to the leftmost side of the bottom of the control frame 6, and the second linear slide 12 is used to control the connecting frame 14 to slide to the top of the left unloading frame 2. At this time, the electric control rotator 16 inside the connecting frame 14 controls the rotating shaft 17 to flip 90 degrees, so that the positioning frames 18 on one side of the two rotating shafts 17 are in a vertical state. At this time, the driving end of the second servo electric cylinder 13 is used to control the connecting frame 14 to move downward. According to the specifications of the wheelchair frame, two sets of first electric slides 15 are used to control the two rotating shafts 17 to approach the two sides of the wheelchair frame. Then, the two sides of the wheelchair frame are inserted into the positioning grooves 19 inside the positioning frames 18 on both sides, and the wheelchair frame is clamped and positioned by the two positioning clamps 20 inside the positioning grooves 19. The clamping and positioning of the positioning frames 18 on both sides and the clamping and positioning of the upper and lower positioning clamps 20 can ensure the stability of the wheelchair frame during feeding and processing to the greatest extent.

[0066] Step 2: The lifting frame 11 is driven to slide to the top of the connecting groove 21 by the first linear slide rail 9, and the lifting frame 11 is controlled to move downward by the two first servo electric cylinders 10 until the surrounding of the lifting frame 11 and the surrounding of the inner wall of the connecting groove 21 are sealed and connected. A sealing ring is sleeved around the lifting frame 11 to ensure the sealing of the connection between the lifting frame 11 and the connecting groove 21, so that the wheelchair frame is processed inside the connecting groove 21;

[0067] Step 3: a polishing chamber 23 is arranged at the leftmost side of the connecting groove 21, and the wheelchair frame is put into the vibration polishing container 27 as a whole. The polishing medium and polishing liquid in the vibration polishing container 27 are used to vibrate with the vibration polishing machine 28 arranged at the bottom of the vibration polishing container 27, so that the polishing medium and polishing liquid are fully in contact with the surface of the wheelchair frame, thereby quickly completing the polishing process on the surface of the wheelchair frame. Then, the movable partition 22 on one side of the polishing chamber 23 is controlled to descend, and the wheelchair frame after the surface polishing process is immediately sent into the activation chamber 24 for the next processing step.

[0068] Step 4: introducing a chemical solvent into the activation etching container 32 through the activation solvent feed port, immersing the entire wheelchair frame in the chemical solvent, removing the oxide film on the surface of the wheelchair frame and increasing the surface activity, then electroplating the surface of the wheelchair frame, adjusting the distance between the electrode plates on both sides according to the specifications of the wheelchair frame, using the second electric slides 35 on both sides to control the two adjustment racks 36 to adjust the position inside the electroplating container 33, accurately adjusting the distance between the two electrode plates, ensuring the discharge intensity of the plasma and the stability of the treatment effect, so that the electroplating layer can be evenly and densely deposited on the surface of the wheelchair frame;

[0069] Step 5. Finally, the wheelchair frame is transferred to the interior of the air-drying container 40. A top-down gas flow is formed inside the air-drying container 40 through the upper and lower air-drying annular tubes 41, thereby quickly completing the air-drying treatment on the surface of the wheelchair frame. This can prevent rust or corrosion on the surface caused by residual water stains, and also save time for subsequent processing or packaging steps, effectively reducing the production cycle and improving the efficiency of the entire production line.
