Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a rust removal pretreatment mechanism for metal surface treatment before electroplating. Background Technology

[0002] In electroplating, the pretreatment of metal surfaces is crucial, especially the rust removal process, which directly affects the adhesion, uniformity, and corrosion resistance of the coating. Traditional pretreatment typically includes mechanical rust removal (such as sandblasting), chemical pickling, or electrolytic degreasing. Modern high-efficiency pretreatment systems tend to integrate ultrasonic cleaning, dynamic rinsing, and chemical synergy, achieving efficient and uniform rust removal through automated control while minimizing damage to the substrate, thus meeting the diverse needs of precision parts and mass production.

[0003] According to CN220635594U, a rust removal device for metal surface treatment is disclosed. This technology discloses "a rust removal device for metal surface treatment, including a workbench, an ultrasonic rust removal box fixedly installed on the top of the workbench, a circulating water tank fixedly connected to the left side of the ultrasonic rust removal box, a lifting mechanism provided on the top of the ultrasonic rust removal box, a rust removal basket provided at the bottom of the lifting mechanism, a crossbar fixedly connected to the top of the lifting mechanism, pulleys fixedly installed at both ends of the crossbar, the pulleys slidably connected in a slide rail, and a drying mechanism provided on the right side of the ultrasonic rust removal box." This device has the technical advantages of "using an ultrasonic rust removal box and a circulating water tank to filter and replace wastewater generated during rust removal, using a drying mechanism to quickly dry the surface of the workpiece after rust removal with the assistance of the lifting mechanism and pulleys, and using a drain trough to collect the rust remover dripping from the rust removal basket."

[0004] In the existing technology, during the rust removal pretreatment of metal workpieces before electroplating, the use of a fixed loading rack structure makes it impossible to flexibly adjust the loading spacing according to the size and shape of different workpieces. This results in the workpieces being stacked tightly and severely obscured during cleaning, making it difficult for ultrasonic energy to be applied evenly to all workpiece surfaces, leading to incomplete rust removal and inconsistent cleaning results. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rust removal pretreatment mechanism for metal surface treatment before electroplating. Through adjustable spacing design and optimized fluid channels, it achieves flexible adaptation of workpiece loading and efficient circulation of cleaning fluid, which not only improves the processing adaptability of workpieces of different sizes, but also ensures uniform and stable cleaning effect. It effectively solves the problems of traditional fixed loading and liquid retention, and significantly improves pretreatment efficiency and quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-treatment mechanism for rust removal before electroplating in metal surface treatment, comprising a machine body, wherein a loading mechanism is provided on the machine body for loading workpieces, and the loading mechanism includes:

[0007] The main components include a basket mounted on the machine body, with a base plate fixed to the lower end of the basket;

[0008] The support assembly includes a storage slot placed on the base plate, and the storage slot has several through holes arranged in an array inside;

[0009] The adjustment assembly includes cylindrical seats fixed at the four corners of the bottom of the storage compartment. A threaded knob is rotatably installed on the outer wall of the lower end of the cylindrical seat. A threaded rod is slidably installed through the inside of the cylindrical seat, and the outer wall of the threaded rod is threaded to the inner wall of the threaded knob. A plug is fixed at the bottom of the threaded rod.

[0010] Preferably, the adjusting assembly further includes a guide groove formed on the outer wall of the threaded rod, and a threaded hole is formed inside the cylinder seat, with an internal hexagon bolt threaded inside the threaded hole.

[0011] Preferably, the support assembly further includes elongated holes formed inside the four ends of the storage slot.

[0012] Preferably, a cleaning tank is fixed inside the machine body, and a storage tray is placed inside the cleaning tank. Several transducers are installed in an array at the bottom of the cleaning tank, and an ultrasonic generator is installed on the right side inside the machine body.

[0013] Preferably, an extension cavity is fixed at the left end of the cleaning tank, and an electric heating tube is installed inside the extension cavity.

[0014] Preferably, a cushioning pad is fixed to the top of the body and is made of a corrosion-resistant elastic material.

[0015] Beneficial effects

[0016] This invention provides a rust removal pretreatment mechanism for metal surface treatment before electroplating. Compared with the prior art, it has the following advantages:

[0017] 1. By rotating the threaded knob to adjust the length of the threaded rod extension, the spacing of each support component can be adjusted. This allows the loading mechanism to quickly adjust the loading spacing and layer distribution according to the size characteristics and process requirements of different workpieces, effectively solving the technical problem that traditional fixed loading racks cannot adapt to diverse workpieces. While ensuring loading stability, the overall mechanism greatly improves the convenience of workpiece loading and unloading, providing an efficient and reliable workpiece bearing solution for electroplating pretreatment processes.

[0018] 2. The elongated holes facilitate the movement of the storage tank and create a fluid channel that runs through the tank, allowing the cleaning fluid to circulate more smoothly under the action of ultrasound, effectively solving the problem of liquid retention caused by traditional closed storage tanks.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a rust removal pretreatment mechanism for metal surface treatment before electroplating, including a machine body 1, a loading mechanism 2 provided on the machine body 1 for loading workpieces, the loading mechanism 2 including:

[0028] The main component 21 includes a basket 211 mounted on the body 1, with a base plate 212 fixed to the lower end of the basket 211;

[0029] The support assembly 22 includes a storage slot 221 placed on the base plate 212, and the storage slot 221 has a plurality of through holes 222 arranged in an array inside.

[0030] The adjustment component 23 includes a cylindrical base 231 fixed at the four corners of the bottom of the storage slot 221. A threaded knob 232 is rotatably installed on the outer wall of the lower end of the cylindrical base 231. A threaded rod 233 is slidably installed inside the cylindrical base 231, and the outer wall of the threaded rod 233 is threadedly installed with the inner wall of the threaded knob 232. A plug 234 is fixed at the bottom of the threaded rod 233.

[0031] In this embodiment, the length of the threaded rod 233 is adjusted by rotating the threaded knob 232, thereby adjusting the spacing of each support component 22. This allows the loading mechanism 2 to quickly adjust the loading spacing and layer distribution according to the size characteristics and process requirements of different workpieces, effectively solving the technical problem that traditional fixed loading racks are difficult to adapt to diverse workpieces. While ensuring loading stability, the overall mechanism greatly improves the convenience of workpiece loading and unloading, providing an efficient and reliable workpiece bearing solution for the electroplating pretreatment process.

[0032] Specifically, the adjusting component 23 also includes a guide groove 235 on the outer wall of the threaded rod 233, and a threaded hole 236 is provided inside the cylinder seat 231. An internal hexagon bolt 237 is installed inside the threaded hole 236.

[0033] In this embodiment, the rotation of the threaded rod 233 is restricted by the internal hex bolt 237 and the guide groove 235, so that it can only move linearly along the axial direction.

[0034] Specifically, the support assembly 22 also includes elongated holes 223 formed inside the four ends of the storage slot 221.

[0035] In this embodiment, the elongated hole 223 facilitates the movement of the storage tank 221 and forms a fluid channel that runs through the tank, allowing the cleaning fluid to form a smoother convection circulation under the action of ultrasound, effectively solving the liquid retention problem caused by the traditional closed storage tank 221.

[0036] Specifically, a cleaning tank 3 is fixed inside the body 1, and a storage slot 221 is placed inside the cleaning tank 3. Several transducers 4 are arranged in an array at the bottom of the cleaning tank 3, and an ultrasonic generator 5 is installed on the right side inside the body 1.

[0037] In this embodiment, the array of transducers 4 at the bottom of the cleaning tank 3, together with the ultrasonic generator 5 integrated on the right side of the body 1, constitutes a multi-band ultrasonic generation system, which can generate a uniform and penetrating ultrasonic field.

[0038] Specifically, an extension cavity 6 is fixed to the left end of the cleaning tank 3, and an electric heating tube 7 is installed inside the extension cavity 6.

[0039] In this embodiment, the heating element 7 can uniformly heat the cleaning solution in the cleaning tank 3, avoiding localized excessively high or low temperatures and ensuring stable solution temperature. Through the layout of the extension cavity 6, the heating element 7 and the cleaning tank 3 form an integrated heating system, which not only improves heat transfer efficiency but also reduces heat loss, thereby significantly enhancing the activity of the cleaning solution, accelerating rust dissolution and oil removal, and ensuring the high efficiency and stability of the rust removal pretreatment process before electroplating.

[0040] Specifically, a buffer pad 8 is fixed to the top of the fuselage 1 and is made of corrosion-resistant elastic material.

[0041] In this embodiment, the vibration energy generated during the operation of the ultrasonic wave can be effectively absorbed to prevent the mechanical structure from loosening due to long-term vibration, and the direct collision damage between the storage slot 211 and the body 1 can be avoided.

[0042] The working principle and usage process of this utility model are as follows: First, by rotating the threaded knob 232 to adjust the length of the threaded rod 233, the spacing of each support component 22 is adjusted; this allows the loading mechanism 2 to quickly adjust the loading spacing and layer distribution according to the size characteristics and process requirements of different workpieces, effectively solving the technical problem that traditional fixed loading racks are difficult to adapt to diverse workpieces. While ensuring loading stability, the overall mechanism greatly improves the convenience of workpiece loading and unloading, providing an efficient and reliable workpiece bearing solution for the electroplating pretreatment process.

[0043] The array of transducers 4 at the bottom of the cleaning tank 3, combined with the ultrasonic generator 5 integrated on the right side of the main body 1, forms a multi-band ultrasonic generation system capable of generating a uniform and penetrating ultrasonic field. The heating element 7 evenly heats the cleaning solution within the cleaning tank 3, preventing localized overheating or underheating and ensuring stable solution temperature. Through the layout of the extension cavity 6, the heating element 7 and the cleaning tank 3 form an integrated heating system, which not only improves heat transfer efficiency but also reduces heat loss, thereby significantly enhancing the activity of the cleaning solution, accelerating rust dissolution and oil removal, and ensuring the high efficiency and stability of the rust removal pretreatment process before electroplating.

[0044] Furthermore, the elongated hole 223 facilitates the relocation of the storage tank 221 and forms a fluid channel that runs through the tank, allowing the cleaning fluid to form a smoother convection circulation under the action of ultrasound, effectively solving the problem of liquid retention caused by the traditional closed storage tank 221.
