[0003] Chemical plating is a process of reducing metals on a metal surface without the application of an external current, using a reducing agent in the solution to provide the electrons needed for the reduction of metal ions. Compared to electroplating, chemical plating technology offers advantages such as uniform coating, suitability for various conductive and non-conductive materials with complex shapes, less environmental pollution, and lower cost. Due to its numerous advantages, it has replaced electroplating in many fields, becoming a new and environmentally friendly surface treatment process that has attracted much attention and is currently widely used in various sectors of the electronics, automotive, and aerospace industries.

[0004] Electroless plating has made great strides with the development of high technology. In electroless plating, polydopamine coatings can be customized as coatings for different functional applications. The surface of polydopamine has a large number of active functional groups, which gives it good adhesion properties, facilitates secondary reactions, and can also resist Ag. + Fe 3+ Cu 2+ The adsorption of metal ions is achieved. This method was demonstrated by depositing silver and copper metal films by impregnating objects coated with polydopamine in silver nitrate and copper chloride solutions, respectively.

[0005] The process of using polydopamine for electroless plating often involves complex procedures. The properties of polydopamine itself dictate that it must be prepared and used immediately.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed embodiments of the present invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 and Figure 2 The device for metallizing non-metallic parts shown includes an integral frame 10, an integrated reaction zone 20 disposed within the integral frame 10, a liquid dispensing platform 30 disposed on one side of the integral frame 10, and a transfer component 40 disposed between the integrated reaction zone 20 and the liquid dispensing platform 30 for transferring beakers or solutions on the liquid dispensing platform 30 to the integrated reaction zone 20.

[0026] A rotating tray assembly 50 is provided on the integrated reaction zone 20. The rotating tray assembly 50 includes a rotating tray 51 that can rotate along its central axis. The top of the rotating tray 51 is provided with a plurality of support holes along its circumference for supporting reaction beakers or drying barrels 55, and at least one support hole is used to place a drying barrel 55.

[0027] A support assembly 60 for placing and controlling the lifting and lowering of non-metallic parts is provided on the side of the rotating tray 51 away from the transfer assembly 40. The support assembly 60 includes a support container 61 for placing the non-metallic parts, and the support container 61 has a mesh-like structure. The mesh-like structure enables the support container 61 to carry non-metallic parts and also allows the non-metallic parts to fully contact the reaction solution and react.

[0028] A raw material beaker containing raw materials is placed on the solution preparation platform 30. The transfer component 40 sequentially transfers the raw materials to the corresponding reaction beakers on the rotating tray 51 for solution preparation. A reaction beaker containing the reaction solution is placed on the solution preparation platform. The transfer component 40 transfers the reaction solution and reaction beakers to the corresponding support holes on the rotating tray 51 for reaction. The rotating tray component 50 is also equipped with a drying tank. The rotating tray component 50 and the support component 60 cooperate with each other to allow non-metallic parts to undergo alcohol cleaning, drying, surface polydopamine treatment, deionized water cleaning, air cooling, adsorption of palladium nanoparticles, and metallization reaction in sequence. This technical solution integrates solution preparation, transfer, reaction, cleaning, drying, and cooling, improving space utilization, reducing personnel operation time, and reducing the difficulty of metallization reaction operation.

[0029] The rotating pallet assembly 50 also includes a rotating motor 52 and several support rollers 56.

[0030] The rotary motor 52 is fixedly installed at the bottom of the overall frame 10, and the output end of the rotary motor 52 is fixedly connected to the central axis of the rotary tray 51; the support rollers 56 are slidably installed in the integrated reaction zone 20, the fixed ends of several support rollers 56 are circumferentially installed at the bottom of the rotary tray 51, and the movable ends of several support rollers 56 are tangent to the bottom of the overall frame 10.

[0031] The stability of the rotating tray 51 is improved by the support roller 56, and the rotation accuracy of the rotating motor 52 is improved.

[0032] A support slide rail 561 is provided below the support roller 56 to restrict the movement direction of the support roller 56 in order to ensure the support stability of the support roller 56.

[0033] At the same time, the sensor provides feedback on the rotation angle of the rotating tray 51, so that the rotating tray 51 can rotate at a fixed angle, ensuring that the non-metallic parts in the support container 61 can be accurately positioned and fully contacted with the reaction solution.

[0034] like Figure 4 As shown, the top of the rotating tray 51 is provided with 6 support holes, namely the first support hole 531, the second support hole 532, the third support hole 533, the fourth support hole 534, the fifth support hole 535 and the sixth support hole 536. The support holes are distributed around the circumference, are cylindrical and have a bottom, and are used to support the beaker.

[0035] A first reaction beaker 541 is provided on the first support hole 531. The first reaction beaker 541 is used to hold alcohol to clean non-metallic parts, remove residual impurities such as resin from their surface, and prevent them from affecting the subsequent metallization process.

[0036] A matching second reaction beaker 542 is provided on the second support hole 532. The second reaction beaker 542 is used to hold the hydrochloric acid dopamine solution. After the non-metallic parts are cleaned and dried with alcohol, they are placed into the second reaction beaker 542 in the support container 61 to carry out the surface polydopamine growth process.

[0037] A matching third reaction beaker 543 is provided on the third support hole 533. The third reaction beaker 543 is used to hold the prepared palladium nanoparticle solution. Non-metallic parts that have been treated with polydopamine in the second reaction beaker 542 are immersed in the third reaction beaker 543, and the adsorption process of palladium nanoparticles can be carried out in an environment of 40 degrees.

[0038] A matching fourth reaction beaker 544 is provided on the fourth support hole 534. The fourth reaction beaker 544 is used to hold the metallization solution. Non-metallic parts that have been cleaned with deionized water and adsorbed with nano-target particles can be placed in this area for metallization treatment.

[0039] A fifth reaction beaker 545 is provided on the fifth support hole 535. The fifth reaction beaker 545 is used to hold deionized water for cleaning non-metallic parts.

[0040] Stirring bars are placed in the first reaction beaker 541 and the fourth reaction beaker 544, and magnetic stirrers are installed below them to achieve thorough cleaning of non-metallic parts; stirring bars are placed in the second reaction beaker 542, the third reaction beaker 543, and the fifth reaction beaker 545, and magnetic stirrers are installed below them. When preparing the reaction solution, the stir bar rotates to ensure that the raw material solution is fully mixed; during the reaction, the stir bar stirs the reaction solution and drives the non-metallic parts to fully contact the reaction solution to ensure the reaction effect.

[0041] A temperature thin-film sensor 555 is installed inside the third reaction beaker 543, and a heating tube 552 is installed at the bottom to meet the temperature requirements of the reaction.

[0042] like Figure 5 and Figure 6 As shown, a matching drying drum 55 is provided on the sixth support hole 536 for drying non-metallic parts.

[0043] A temperature film sensor 555 is installed on the inner wall of the drying drum 55, which can monitor the temperature inside the drying drum 55 in real time. Then, the temperature inside the drying drum 55 is precisely controlled by the heating tube 552 and the fan 553 to meet the requirements of constant temperature and drying.

[0044] An air inlet 551 is provided at the bottom of the drying drum 55. A heating element 552 and a fan 553 are arranged sequentially from bottom to top in the drying drum 55. When the fan 553 rotates, air is drawn in through the air inlet 551 at the bottom of the drying drum 55, and the resulting centrifugal airflow blows the air out from bottom to top. If the heating element 552 at the bottom is energized and heated, hot air is blown out to dry the non-metallic parts. If the selector switch prevents the heating element 552 from being energized and heated, cold air is blown out to dry the non-metallic parts. When the fan 553 is turned off, the non-metallic parts are cooled.

[0045] Meanwhile, a parts placement area 554 is designed above the fan 553 to store non-metallic parts, separating the fan 553 from the non-metallic parts.

[0046] To enhance heating efficiency, the drying drum 55 is made of heat-insulating material. A shutter 556 is installed at the outlet at the top of the drying drum 55. The shutter 556 can be controlled by sending an electrical signal through the control board. The shutter 556 is opened and closed by opening and closing, which can meet the needs of parts loading and unloading and cooling treatment while improving heating efficiency.

[0047] An opening 557, which is adapted to the size of the cantilever beam 62, is provided on the side wall of the drying drum 55 to ensure that the shutter 556 can open and close normally while maintaining the heat preservation effect of the drying drum 55.

[0048] Multiple functional components are installed in the drying drum 55. These components work together to achieve multiple functions such as drying, air drying, and cooling, thereby improving space utilization and avoiding redundant structures.

[0049] like Figure 1 and Figure 2 As shown, the support assembly 60 also includes a ball screw 63 with its axis perpendicular to the rotating tray 51, and one end of the ball screw 63 is connected to a reaction motor 64. The lifting slider 631 of the ball screw 63 is fixedly connected to the support container 61 through the cantilever beam 62, and the lifting direction of the support container 61 passes through the circumference where the support hole is located.

[0050] The separation and contact between non-metallic parts and solution are achieved by moving the support container 61 up and down. When the support container 61 rises, the rotating tray 51 rotates to a state where the support container 61 is opposite to the next reaction beaker, and then the support container 61 is lowered, thereby advancing the reaction process.

[0051] Because the replacement speed of non-metallic parts reacting with different solutions is required to be high, after the reaction in the beaker of the previous reaction is completed, the non-metallic parts need to be immediately transferred into the solution of the next reaction. In this embodiment of the invention, a ball screw 63 is selected. The ball screw 63 reduces the interval between taking out and immersing in the previous and subsequent reactions. At the same time, the rolling of the ball between the screw and the nut can reduce friction and wear, thereby improving the accuracy of motion control.

[0052] The cantilever beam 62 and the lifting slider 631 are bolted together, allowing the non-metallic parts to extend laterally into the reaction beaker for reaction. The ball screw 63 is mounted within the overall frame 10 using a double-end fixing method via bearings 632 and snap rings 633. One end of the ball screw 63 is connected to the output end of the reaction motor 64. By adopting a double-end fixing installation method, with both ends connected to the support base via bearings 632 and snap rings 633, this connection method can reduce friction and improve motion transmission efficiency while also providing a positioning and fastening function.

[0053] The reaction motor 64 is a 3508 motor. The 3508 brushless DC motor is fixed on the overall frame 10 by a support base. The output shaft of the 3508 motor is connected to a small synchronous pulley by a flat key. The end of the lead screw is also connected to a large synchronous pulley by a flat key. The motion is transmitted between the two synchronous pulleys by a synchronous belt.

[0054] This transmission mode ultimately transforms the rotational motion of the motor output shaft into the longitudinal translation of the lifting slider 631. Meanwhile, the 3508 motor has a relatively small torque, outputting only 2.8 N·m of continuous torque, and a relatively high speed, reaching 469 rpm. By using different toothed synchronous belt pulleys for connection, it can reduce speed and increase torque, thereby reducing transmission speed while increasing transmission torque.

[0055] To ensure the accuracy of motion transmission between the two pulleys, a small tensioning pulley is added between the pulleys to tension the synchronous belt and prevent step loss.

[0056] The overall frame 10 has several openings that connect the inside and outside of the overall frame 10, serving as inlets for the solution. A solution preparation platform 30 extends from the openings, which is used to place beakers or reaction beakers containing raw materials.

[0057] like Figure 3 and Figure 7 As shown, to achieve the transfer of beakers or solutions, the transfer assembly 40 includes a robotic arm 41 and a vertical slide rail 42, a longitudinal slide rail 43, and a transverse slide rail 44.

[0058] During reaction preparation, the operator places the reaction beakers containing the reaction solution onto the liquid preparation platform 30 in sequence, and controls the robotic arm 41 to pick up the reaction beakers and place them at the corresponding positions on the rotating tray 51.

[0059] As an alternative implementation method, when preparing the solution, the operator places the raw material beaker containing the raw materials on the solution preparation platform 30 in sequence, controls the robotic arm 41 to pick up the raw material beaker, and controls the tilt angle of the beaker to pour the raw materials into the reaction beaker on the rotating tray 51, thereby preparing the reaction solution.

[0060] A pair of parallel vertical slide rails 42 are provided inside the overall frame 10. The direction of both vertical slide rails 42 is perpendicular to the plane where the support hole is located, and a matching vertical slider 421 is provided. The vertical slide rails 42 and the vertical slider 421 enable the robotic arm 41 to move up and down along a path perpendicular to the rotating tray 51.

[0061] Two vertical sliders 421 are each fixedly connected to a longitudinal slide rail 43. The direction of the longitudinal slide rail 43 is perpendicular to the direction of the vertical slide rail 42. The two longitudinal slide rails 43 are parallel to each other and each is provided with a matching longitudinal slider 431. The two longitudinal sliders 431 are respectively fixedly connected to both ends of a transverse slide rail 44. The direction of the transverse slide rail 44 is perpendicular to both the direction of the vertical slide rail 42 and the direction of the longitudinal slide rail 43. A matching transverse slider 441 is provided on the transverse slide rail 44. The longitudinal slide rails 43 and longitudinal sliders 431, and the transverse slide rails 44 and transverse sliders 441 enable the robotic arm 41 to move along a plane parallel to the rotating tray 51.

[0062] When adding raw material solution, the positioning accuracy and stability of the robotic arm 41 are crucial factors in achieving quantitative addition of raw materials. To improve the positioning accuracy of the robotic arm 41, this embodiment of the invention uses a lead screw and a motor to control the movement of each slider. The vertical slider 421 is connected to the longitudinal slide rail 43 via a first connecting block 422. The first connecting block 422 is equipped with a vertical lead screw 423 whose axis is parallel to the direction of the vertical slide rail 42. A first motor 424 is installed at one end of the vertical lead screw 423 and is fixed within the overall frame 10.

[0063] A pair of longitudinal slide rails 43 are provided, and a transverse slide rail 44 is connected between the pair of longitudinal slide rails 43. A robotic arm 41 is provided on the transverse slider 441 on the transverse slide rail 44. Therefore, keeping the transverse slide rail 44 and the rotating tray 51 parallel is an important condition for improving the stability of the robotic arm 41. In this embodiment of the invention, two vertical lead screws 423 and a first motor 424 are provided. The two first motors 424 rotate synchronously, so that the transverse slide rail 44 and the rotating tray 51 remain parallel.

[0064] The longitudinal slider 431 and the transverse slide rail 44 are connected by a second connecting block 432. The second connecting block 432 is provided with a longitudinal lead screw 433 whose axis is parallel to the longitudinal slide rail 43.
