Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, specifically to an electroplating post-processing device. Background Technology

[0002] After electroplating, metal workpieces require post-processing steps such as cleaning to remove residual plating solution and heating to remove residual hydrogen gas from the workpiece. The dehydrogenation process involves continuous heating of the metal workpiece at high temperatures to allow the hydrogen gas to escape. Following dehydrogenation, subsequent passivation processes are performed. However, because the metal workpiece is heated to a high temperature during dehydrogenation, direct handling could cause burns to workers. Furthermore, the hot workpiece remains at a high temperature when moved to the passivation area, which could interfere with the passivation process. Therefore, cooling is necessary to lower the temperature of the metal workpiece.

[0003] However, most existing technologies directly cool metal workpieces using fans. Since the dehydrogenation equipment radiates a large amount of heat during heating, and the metal workpieces exposed to air after dehydrogenation also radiate heat, the air temperature around the dehydrogenation equipment is relatively high. Therefore, the air blown out by the fan is close to the surface temperature of the metal workpiece, resulting in low cooling efficiency. In view of this, we propose a post-electroplating treatment device. Utility Model Content

[0004] The purpose of this utility model is to provide an electroplating post-treatment device that solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An electroplating post-processing device, comprising a housing;

[0007] The bottom of the box is equipped with a cooling mechanism, and the top of the box is equipped with a hydrogen removal mechanism.

[0008] The cooling mechanism includes a cold water pipe, which is arranged around the inside of the housing. A guide plate is fixedly connected to the bottom of the housing, and the guide plate has a spiral structure.

[0009] Preferably, a circulation chamber is fixedly connected inside the box body. The circulation chamber has a ring structure, and the cold water pipe is arranged around the inside of the circulation chamber. The circulation chamber is opened on the inner wall of the box body, and a through hole is opened on the side of the circulation chamber.

[0010] Preferably, a support ring is rotatably connected inside the circulation chamber, a guide plate is fixedly connected to the support ring, and a toothed ring is fixedly connected to the outside of the support ring.

[0011] Preferably, a motor is fixedly connected to the bottom of the housing, the output shaft of the motor passes through the housing and is connected inside the housing, and a gear that meshes with a gear ring is fixedly connected to the end of the motor output shaft.

[0012] Preferably, the hydrogen removal mechanism includes a support rod, which is fixedly connected to the middle of the inside of the housing, and a support plate is fixedly connected to the outside of the support rod. The support plate has a spiral mesh structure.

[0013] Preferably, a heating rod is fixedly connected to the support rod, and a heat-conducting shell is fixedly connected to the outside of the heating rod, with the heat-conducting shell passing through the support plate.

[0014] Preferably, a feed hopper is fixedly connected to the top of the box, a collection frame is movably connected to the middle of the bottom of the box, the collection frame corresponds to the guide plate, and a support leg is fixedly connected to the bottom of the box.

[0015] By employing the above technical solution, this utility model provides an electroplating post-processing equipment that has at least the following beneficial effects:

[0016] (1) The present invention uses a cooling pipe in conjunction with a circulation chamber to cool the air inside the circulation chamber by using the wastewater generated during the cleaning process. This allows the air to flow along the guide plate and gradually cool the metal workpiece on the guide plate by gradually reducing the temperature of the air. This avoids the sudden cooling of the metal workpiece and can also quickly reduce the temperature of the metal workpiece to the set range, thereby improving the efficiency of subsequent post-processing.

[0017] (2) The present invention can form an air barrier at the bottom of the inside of the processing box by setting a circulating cooling mechanism, thereby preventing outside air from entering the inside and keeping the high temperature dehydrogenation processing space at the top of the inside within a high temperature range, thus reducing the heating power during the dehydrogenation process.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] An electroplating post-processing device, such as Figures 1-4 As shown, it includes a housing 1; the bottom of the housing 1 is equipped with a cooling mechanism 2, which can use the cleaning water in the post-processing to cool the residual heat of the workpiece after heating and dehydrogenation, thereby making full use of the cleaning wastewater and improving the cooling efficiency of the workpiece by utilizing the low temperature of the wastewater.

[0028] Specifically, the cooling mechanism 2 includes a cold water pipe 21, which is arranged around the inside of the housing 1. The outer wall of the cold water pipe 21 is made of a heat-conducting material, which can quickly transfer the high temperature inside the housing 1 to the wastewater inside the cold water pipe 21, thereby achieving rapid cooling inside the housing 1. A guide plate 22 is fixedly connected to the bottom of the inside of the housing 1. The guide plate 22 has a spiral structure, which can guide the workpiece, allowing the workpiece to slide along the guide plate 22 and be cooled down during the sliding process.

[0029] It is worth noting that a circulation chamber 23 is fixedly connected inside the housing 1. The circulation chamber 23 has a ring-shaped structure, and a cold water pipe 21 is arranged around it. The structure of the circulation chamber 23 can cooperate with the cold water pipe 21 to continuously cool the circulating air. The circulation chamber 23 is located on the inner wall of the housing 1, and a through hole 24 is provided on the side of the circulation chamber 23. The through hole 24 is located in the middle and bottom of the housing 1, so that the circulation chamber 23 is connected to the top and bottom of the guide plate 22, respectively. This allows air to flow from the bottom of the guide plate 22 to the top of the guide plate 22, and the airflow blows away the residual heat on the surface of the workpiece.

[0030] Based on this, a support ring 25 is rotatably connected inside the circulation chamber 23, and a guide plate 26 is fixedly connected to the support ring 25. The structure of the support ring 25 can support the guide plate 26, and the guide plate 26 can rotate with the support ring 25, driving the air inside the circulation chamber 23 to flow during the rotation. A toothed ring 27 is fixedly connected to the outside of the support ring 25. The structure of the toothed ring 27 can drive the support ring 25, so that the support ring 25 rotates continuously.

[0031] Furthermore, a motor 28 is fixedly connected to the bottom of the housing 1. The output shaft of the motor 28 passes through the housing 1 and is connected inside the housing 1. A gear 29 that meshes with the gear ring 27 is fixedly connected to the end of the output shaft of the motor 28. The structure of the motor 28 can drive the gear ring 27 through the gear 29.

[0032] Example 2

[0033] like Figures 1-5 As shown, based on Example 1, a hydrogen removal mechanism 3 is provided at the top of the inside of the box 1; the hydrogen removal mechanism 3 can continuously heat the workpiece entering the box 1, thereby using high temperature to dry the residual cleaning water on the surface of the workpiece and to remove hydrogen from the workpiece, thus facilitating subsequent collection and packaging operations.

[0034] In this embodiment, the hydrogen removal mechanism 3 includes a support rod 31, which is fixedly connected to the middle of the inside of the housing 1. A support plate 32 is fixedly connected to the outside of the support rod 31. The support plate 32 has a spiral mesh structure. The support rod 31 can support the support plate 32. At the same time, the mesh structure can facilitate the evaporation or dripping of residual cleaning water on the surface of the workpiece, thereby improving the drying effect on the workpiece. Meanwhile, the mesh structure hinders the sliding of the workpiece through the mesh holes on the surface, thereby reducing the sliding speed of the workpiece along the support plate 32 during the hydrogen removal process, and thus increasing the heating and hydrogen removal time of the workpiece.

[0035] In addition, a heating rod 33 is fixedly connected to the support rod 31, and a heat-conducting shell 34 is fixedly connected to the outside of the heating rod 33. The heat-conducting shell 34 passes through the support plate 32. The structure of the heating rod 33 can continuously heat the top of the inside of the box 1, and the structure of the heat-conducting shell 34 can evenly transfer the heat generated by the heating rod 33 during operation to the support plate 32.

[0036] Based on this, a feed hopper 4 is fixedly connected to the top of the box 1, and a collection frame 5 is movably connected to the middle of the bottom of the box 1. The collection frame 5 and the guide plate 22 are positioned corresponding to each other, and a support leg 6 is fixedly connected to the bottom of the box 1.

[0037] In use, the electroplating post-treatment equipment of this utility model first pours the cleaned workpiece into the box 1 through the feed inlet, and then closes the feed hopper 4 after the feeding operation is completed. The workpiece then falls onto the support plate 32 at the top of the box 1 and slides downward along the spiral support plate 32. During the sliding process, the heating rod 33 continuously runs and continuously heats the support plate 32 and the top of the box 1 through the heat-conducting shell 34. The top of the box 1 and the support plate 32 are at a high temperature, thereby heating the workpiece on the support plate 32, drying the water on the surface of the workpiece, and removing hydrogen from the workpiece. When the workpiece slides to the bottom of the support plate 32, it falls onto the guide plate 22 and slides downward along the guide plate 22. At the same time, the motor 28 starts and drives the gear ring 27 and the support ring 25 to rotate continuously through the gear 29. The guide plate 26 on the inner side of the support ring 25 rotates accordingly and drives the air inside the circulation chamber 23 to flow. Air is discharged from the through-hole 24 at the bottom of the circulation chamber 23, while air is simultaneously drawn into the circulation chamber 23 from the through-hole 24 at the top. Therefore, the air discharged from the bottom through-hole 24 flows upward along the guide plate 22, cooling the workpiece on the guide plate 22. After returning to the circulation chamber 23, the cooling air comes into contact with the cooling pipes, where it is further cooled by the wastewater inside the cooling pipes. As the cooling air flows from the bottom to the top, it continuously blows away heat from the workpiece surface, resulting in a gradual increase in temperature. This achieves a progressive cooling effect, with the temperature gradually decreasing from the top to the bottom of the guide plate 22. This prevents sudden cooling from causing defects in the workpiece surface coating.
