Description

Technical Field

[0001] This invention belongs to the field of passivation technology and relates to a pre-treatment device for drying alloy workpieces. Background Technology

[0002] Passivation refers to the process of treating a metal with strong oxidizing agents or electrochemical methods, causing its surface to become inactive, i.e., passivated. It is a method of slowing down the corrosion rate of a metal by transforming its surface into a state that is less susceptible to oxidation. Additionally, passivation is also called the phenomenon where an active metal or alloy undergoes a significant reduction in chemical activity, becoming a noble metal.

[0003] Currently, many parts on the market require passivation treatment, such as some components in trains. Before passivation, the workpiece surface must first be deburred, then cleaned using ultrasonic cleaning (chemical cleaning to remove surface oil and other contaminants). After chemical cleaning, it is rinsed with clean water, then treated with a passivation solution, and finally dried to complete the passivation process. To improve drying efficiency, workers often manually blow water onto the workpiece using an air hose between passivation and drying to accelerate the drying process.

[0004] Since many parts are not simply plate-shaped or column-shaped, but rather have more complex shapes, it takes a long time to thoroughly blow paint using a spray nozzle. However, if you blow paint quickly, the water-blowing effect is poor and there is a lot of residue, resulting in poor performance. Summary of the Invention

[0052] The free end of the adjustment part 29 is provided with a cylindrical unlocking hole 31.

The middle part of the anti-rotation rod 35 is attached to the inner wall of the first anti-rotation hole 32 and the second anti-rotation hole 33.

[0054] This invention provides a pre-drying treatment device for alloy workpieces. After passivation and cleaning, the worker first places the cleaned workpiece onto a conveyor belt 3, or the workpiece is conveyed by another conveyor belt or moved onto the conveyor belt 3 by a robotic arm. Then, a first drive mechanism drives a first support roller 2 to rotate, simultaneously moving the workpiece forward on the conveyor belt 3. At the same time, a blower blows high-pressure air into a first air blowing pipe 4, and the high-pressure air is blown upward through a first air blowing head 5. Since the conveyor belt 3 is porous, the compressed air can pass through the conveyor belt 3 and act on the lower side of the workpiece, thus effectively blowing away residual water at the bottom of the workpiece. Multiple first air blowing pipes 4 are provided, so that water can be blown away when the workpiece passes through each first air blowing pipe 4, resulting in better water removal and more efficient subsequent drying, leading to better performance. Preferably, the shape of the workpiece to be dried is as follows: Figure 9 As shown, its top is flat, and the bottom has a more complex shape (specifically, parts from a train).

[0055] During transmission, the drive motor 16 drives the drive rod 17 to rotate. The drive rod 17 drives the driven gear 19 to rotate via the drive gear 18. Simultaneously, the driven gear 19 drives one first support roller 2 to rotate, which in turn drives the conveyor belt 3 and another first support roller 2 to rotate. Meanwhile, the drive wheel 25 on the side of the drive gear 18 drives the driven wheel 24 to rotate via the transmission belt 26 (such as a belt or chain). The driven wheel 24 drives one second support roller 9 to rotate via the linkage rod 23, which in turn drives the directional belt 10 and another second support roller 9 to rotate. Both first support rollers 2 and one of the second support rollers 9 have holes in their centers and are movably fitted onto the first bracket 1 and the second bracket 8, respectively. One end of the hole in the center of the other second support roller 9 is rotatably connected to the second support part 21, and the other end is fixedly connected to the linkage rod 23. That is, when the linkage rod 23 rotates, it drives the second support roller 9 to rotate. At the same time, the linkage rod 23 moves through one end of a fall arrestor plate 12, so that one end of the fall arrestor plate 12 is supported by the second bracket 8 and the other end is supported by the linkage rod 23, thus maintaining its stable position.

[0056] When the workpiece is placed on the conveyor belt 3, there is no obstruction from above by the directional belt 10. At the same time, when the workpiece is dried and removed, there is no obstruction from above by the directional belt 10, which makes the actual operation more effective.

[0057] After the workpiece is placed on the conveyor belt 3, it is conveyed forward by the conveyor belt 3 and guided by the guide part 13. It can stably enter between the two anti-fall plates 12 and can be limited by the anti-fall plates 12 during the movement without falling.

[0058] The first air blower 5 blows air upwards to dry the water on the bottom of the workpiece, while the second air blower 15 blows air downwards (the second air pipe 14 is also connected to an external air pump), thus also blowing air onto the upper surface of the workpiece. Therefore, this application can be applied to... Figure 9 The workpiece in the text can also be other workpieces.

[0059] Furthermore, the compressed air blown out by the first air blower 5 and the second air blower 15 only passes through one layer of conveyor belt 3 or directional belt 10, which allows the air to act on the workpiece better. Secondly, the anti-fall plate 12 and the support plate 7 can also block the air, allowing the air to pass through the conveyor belt 3 or directional belt 10 better, reducing the amount of air flowing away from the side, and ensuring the water blowing effect on the workpiece from the side.

[0060] Simultaneously, when the workpiece moves, the bottom of the adjusting belt 10 is higher than the workpiece, and the free end of the adjusting rod 11 does not act on the conveyor belt 3; however, the side of the adjusting rod 11 can act on the side of the workpiece. Thus, when the conveyor belt 3 carries the workpiece downstream, the adjusting rod 11 acts on the side of the workpiece from upstream. Under the combined action of the conveyor belt 3 and the adjusting rod 11, the workpiece can rotate at an angle. This causes the workpiece to misalign with the holes (for air passage) on the conveyor belt 3 and the adjusting belt 10, allowing a larger area of ​​the workpiece to be affected by the airflow, resulting in a better blowing effect. Since the adjusting rod 11 is relatively far from the center of the adjusting belt 10 and relatively close to the edge, it mainly acts on the edge or side of the workpiece. This results in a larger swing amplitude and a greater swing effect, while also preventing the adjusting rod 11 from applying excessive driving force to the workpiece, allowing for better separation of the adjusting rod 11 and facilitating the workpiece's normal downstream movement. Furthermore, the projections of the first air pipe 4 and the second air pipe 14 in the vertical direction are misaligned, which effectively prevents the upward and downward airflows from interfering with each other and ensures the water blowing effect.

[0061] Different workpieces have different thicknesses, which affects the required length of the aligning rod 11. For example, thinner workpieces require a longer aligning rod 11; however, thicker workpieces have greater mass, and using a longer aligning rod 11 in this case can easily generate excessive force between the workpiece and the aligning rod 11 (in reality, only slight adjustment of the workpiece angle is needed), resulting in excessive force between the connecting disc 27 and the aligning belt 10, leading to poor performance. Therefore, the length of the aligning rod 11 needs to be adjusted according to actual requirements.

[0062] During adjustment, first use pliers or other tools to insert into the unlocking hole 31 and clamp it onto the removal part 36. Then, remove the removal part 36 outwards. Next, rotate the adjusting part 29 to separate it from the fixing part 28. Then, select the desired length of the adjusting part 29 and thread the threaded part 30 of the adjusting part 29 into the threaded hole. Finally, insert the anti-rotation rod 35 into the first anti-rotation hole 32 and the second anti-rotation hole 33, ensuring that the end of the anti-rotation rod 35 is magnetically attracted to the anti-derailment magnet 34. This completes the adjustment of the length of the directional rod 11. During subsequent use, the anti-rotation rod 35 prevents the adjusting part 29 from rotating relative to the fixing part 28, thus ensuring the stability of their positions.

[0063] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
