[0015] Working principle: This device is used for surface treatment of fixtures during electroplating plate processing. The layered immersion mechanism installed inside the main working kettle is used to carry the copper metal liquid and coolant for the surface attachment treatment of the fixture. The main working kettle is elevated on a fixed base using a suspended frame fixed on the side. The electroplated plate fixture blank to be processed is installed on the metal liquid coating mechanism located inside the main working kettle through the elevated area between the main working kettle and the fixed base. The metal liquid coating mechanism can realize the rotation coating of the fixture blank in the coating metal liquid, and then the height position of the fixture blank can be adjusted through the solid material lifting mechanism installed in the same area as the metal liquid coating mechanism, so as to facilitate the blank to adjust different height positions according to different immersion structure heights. The layered immersion mechanism The annular liquid storage tank 1 and the annular liquid storage tank 2 included are both annular tank structures, which are installed in the main working kettle in the form of an up-and-down longitudinal distribution to maintain the coaxial arrangement between the annular liquid storage tank 1 and the annular liquid storage tank 2, and the annular liquid storage tank 1 and the annular liquid storage tank 2 located inside the main working kettle are provided with circular through holes through which circular through holes can pass. The annular liquid storage tank 1 is filled with a high-temperature copper solution through a set of high-temperature resistant infusion pumps and delivery pipes installed on the fixed base, and the annular liquid storage tank 2 is filled with cooling liquid after attachment through another set of high-temperature resistant infusion pumps and delivery pipes installed on the fixed base. At the same time, the annular liquid storage tank 1 and the annular liquid storage tank 2 can also discharge the internal liquid into the recovery tank for recovery through the discharge pipe installed at the output port, and the solid The small-diameter cylindrical limit frame included in the material lifting mechanism and the medium-diameter cylindrical limit frame and large-diameter cylindrical limit frame included in the metal liquid coating mechanism are mutually fitted and have arc-shaped wing arm structures opposite on both sides. The large-diameter cylindrical limit frame is sleeved on the outside of the medium-diameter cylindrical limit frame, and the medium-diameter cylindrical limit frame is sleeved on the outside of the small-diameter cylindrical limit frame. The large-diameter cylindrical limit frame is rotatably installed in the main working kettle through the top plate and suspension bearing included in the metal liquid coating mechanism, and the three also pass through the circular through holes in the center of the annular liquid storage tank 1 and the annular liquid storage tank 2 at the same time. The small-diameter cylindrical limit frame extends to the top wall of the main working kettle with the fixed port of the base frame installed on the fixed base, and the large-diameter cylindrical limit frame and the medium-diameter cylindrical limit frame are rotatably installed in the main working kettle with the suspension bearing and The top plate is installed on the top wall of the main working kettle as the installation port and extends to the top surface of the base frame. The small-diameter cylindrical limit frame is slidably installed with a group of externally threaded cylinders through the arc-shaped wing plate structures on both sides, so that the externally threaded cylinder is limited to the linear displacement of the small-diameter cylindrical limit frame, and the positioning screw installed on the base frame is synchronously installed inside the small-diameter cylindrical limit frame, and engages with the internal thread groove installed in the externally threaded cylinder. As the driving motor in the base frame generates a rotating torque to drive the positioning screw to rotate inside the small-diameter cylindrical limit frame, the externally threaded cylinder is driven to move up and down along the small-diameter cylindrical limit frame to locate its own height position at any time, and the linkage cylinder included in the metal liquid coating mechanism slides along the arc-shaped wing plate structure of the medium-diameter cylindrical limit frame inside the large-diameter cylindrical limit frame.The middle diameter cylinder limit frame can be driven to rotate by a reciprocating motor installed on the top frame, and the linkage cylinder can be driven to rotate at the same time, and the inlay ring installed on the inner side of the linkage cylinder is embedded in the linkage cylinder installed on the outer surface of the large diameter cylinder limit frame, so that the linkage cylinder can rotate with the middle diameter cylinder limit frame, and the inlay ring can be dragged by the large diameter cylinder limit frame to realize that the linkage cylinder can adjust different height positions synchronously with the large diameter cylinder limit frame when rotating, and the positioning plate installed on the linkage cylinder can also rotate with the linkage cylinder and adjust its own height position, and the linear slide seat installed in a circular distribution at the bottom of the positioning plate limits a group of extension arms of linear displacement respectively, and the extension arm is an L-shaped arm span structure, and the bottom end is installed The fixture fixings can be used to temporarily fix the electroplating plate fixture to be processed, and the arc-shaped wing plate structure of the large-diameter cylindrical limit frame is sleeved on the outside of the linkage cylinder and passes through two sets of limit grooves installed on the positioning plate. The arc angle of the limit groove is greater than the arc angle of the arc-shaped wing plate of the large-diameter cylindrical limit frame, so that the large-diameter cylindrical limit frame will not drive the positioning plate to rotate, and the driving plate installed on the positioning plate is installed on the arc-shaped wing plate structure of the large-diameter cylindrical limit frame, and will rotate with the traction of the large-diameter cylindrical limit frame, and the fine-tuning component included in the metal liquid coating mechanism is installed in the overhead area between the top frame and the main working kettle, the driving plate included in the fine-tuning component is installed on the top of the large-diameter cylindrical limit frame, and the linkage hydraulic component included in the fine-tuning component is fixed on the rotating shaft of the medium-diameter cylindrical limit frame, and the linkage The linkage rack installed at the telescopic end of the dynamic hydraulic component is meshed with the outer tooth key end of the fine-tuning toothed disc, and the mutual meshing of the tooth keys drives the fine-tuning toothed disc and the large-diameter cylindrical limit frame to be locked by the linkage hydraulic component and rotated at a small angle. When the reciprocating motor generates a reciprocating driving force to drive the medium-diameter cylindrical limit frame to rotate reciprocatingly, the fine-tuning component will drive the large-diameter cylindrical limit frame and the driving disc to reciprocate with the medium-diameter cylindrical limit frame and the linkage cylinder. The driving disc is equipped with arc displacement grooves corresponding to the number of linear slides, and each set of corresponding arc displacement grooves and linear slide slots are inlaid with a set of linkage clamping columns, and the set of linkage clamping columns are also installed on the corresponding extension arm of the linear slide limit. With the push of the linkage hydraulic component, the linkage rack is displaced and drives the fine-tuning The gear disc and the large-diameter cylindrical limiting frame that limits the driving disc rotate at a small angle, and the arc-shaped displacement groove on the driving disc, when following the rotation, uses the arc-shaped state characteristics to drive the linkage clamping columns on multiple sets of linear slides to carry the extension arms to move inward or outward at the same time, and also drive the fixture blank fixed by the fixture fixing parts to extend outward and shrink inward, without affecting the reciprocating rotation of the driving disc body following the positioning disc. When the small-diameter cylindrical limiting frame drives the positioning screw to rotate, it drives the external threaded cylinder, the linkage cylinder and the positioning disc to move to the overhead area between the main working kettle and the fixed base, the electroplating plate fixture to be processed can be installed in the equipment through the extension arm, and the reciprocating motor is turned on to drive the fixture blank to follow the reciprocating rotation of the positioning disc, and then by turning on the driving motor,The clamp is driven to pass through the central through holes of the annular liquid reservoir 2 and the annular liquid reservoir 1 in sequence to reach the top of the annular liquid reservoir 1 located inside the main working kettle. In the reciprocating rotation state, the fine-tuning component is opened to drive the extension arm fixed with the clamp blank to expand outward, so that the clamp simultaneously drives the annular liquid reservoir 1 with an annular structure above the liquid storage surface, and lowers the height of the clamp to drive the reciprocatingly rotating clamp to be immersed in the high-temperature copper solution contained in the annular liquid reservoir 1 at the same time. The reciprocating rotation state allows the copper solution to be fully adhered to the surface of the clamp. When the clamp blank follows the solid material lifting mechanism and the metal liquid coating mechanism to descend to the height of the annular liquid reservoir 2 in the reciprocating rotation state, the cooling and curing mechanism installed inside the main working kettle is opened. The exhaust frame included in the cooling and curing mechanism is installed on the top surface of the main working kettle, and the exhaust groove opened therein allows the inside of the main working kettle to be The gas can enter the exhaust frame, and then the air pump structure of the air collecting bucket at the bottom of the main working kettle is opened, so that the annular air supply pipe at the bottom of the air collecting bucket begins to blow air toward the central through-hole position of the annular liquid reservoir 1 and the annular liquid reservoir 2, and the fixture blank with the copper solution on the outer surface is air-cooled, so that the copper solution is initially solidified on the fixture surface, and then the fixture height is adjusted and the fixture position is contracted, and then the fixture is moved to the top of the annular liquid reservoir 2. The fixture with the copper solution attached is driven to immerse into the annular liquid reservoir 2 by the step of immersing in the annular liquid reservoir 1. The reciprocating rotation state of the fixture is used to drive the copper solution attached to the surface to fully cooperate with the fixture and contact the coolant in the annular liquid reservoir 2. The low temperature of the coolant is used to accelerate the thorough solidification of the copper solution on the fixture surface, providing the fixture with good conductivity and corrosion resistance. Finally, the material is collected and the processing is completed.

[0016] The present invention provides a surface treatment device for a plate clamp, which has the following beneficial effects: 1. The present invention has an efficient multi-stage processing flow: through the configuration of the annular liquid reservoir 1 and the annular liquid reservoir 2, the continuous processing flow of the coating is effectively realized, including the filling of the high-temperature copper solution and the application of the coolant. This setting not only optimizes the processing steps, but also improves the overall efficiency of the production process by reducing the processing time and improving the production efficiency.

The cyclic use of the annular liquid reservoir and the precise control of the positioning plate and the linkage cylinder can achieve uniform distribution of the coating on the workpiece, which is crucial to improving the quality and consistency of the product.

[0017] 2. The present invention has the ability to accurately control the position and coating: the position of the fixture and the thickness of the coating can be accurately controlled by using mechanisms such as linkage cylinders, positioning disks and fine-tuning components. These mechanisms ensure the uniformity and consistency of the coating. The annular liquid reservoir and the specially designed coating mechanism can ensure the uniform and accurate application of the coating material (such as copper solution). The cyclic use of the annular liquid reservoir and the precise control of the positioning disk and linkage cylinder can achieve uniform distribution of the coating on the workpiece. By using a drive motor, a reciprocating motor and a fine-tuning component, etc., the position of the workpiece and the coating thickness can be accurately controlled during the coating process. The automated control system reduces human operation errors and improves the accuracy and convenience of repeated operations.

[0018] 3. The present invention has a spatial utilization effect of a composite structure: the space inside the equipment is fully utilized through a composite design of multi-level, annular and nested structures. This design not only saves working space, but also improves the flexibility of operation and the overall functionality of the equipment through the precise coordination of various components. The automated control system and modular mechanism design improve the convenience of operation and the reliability of the equipment. The automated control system can reduce human operational errors and improve the continuity and stability of production.

[0019] 4. Comprehensive temperature and gas management of the present invention: The integration of the cooling and curing mechanism and the exhaust system effectively manages the temperature of the workpiece and the gas environment in the kettle, which is crucial to ensuring the safety and quality of the workpiece processing process. While processing the high-temperature copper solution, the equipment can also perform effective cooling treatment through another annular liquid storage tank. This rapid process from high-temperature coating to cooling and curing not only improves production efficiency, but also ensures the structural stability and durability of the coating.

The main working kettle 1 is elevated on the fixed base 3 using the suspended frame 4 fixed on the side. The electroplating plate fixture blank to be processed is installed on the metal liquid coating mechanism 9 located inside the main working kettle 1 through the elevated area between the main working kettle 1 and the fixed base 3. The metal liquid coating mechanism 9 can realize the rotation coating of the fixture blank in the coating metal liquid, and then the height position of the fixture blank can be adjusted by the solid material lifting mechanism 8 installed in the same area as the metal liquid coating mechanism 9, so as to facilitate the blank to adjust different height positions according to different immersion structure heights.

[0024] Please refer to the attached Figure 1 -Attached Figure 6The layered immersion mechanism 6 is located on the main working kettle 1, and is used to carry the high-temperature metal liquid to be attached to the surface and for the fixture to be immersed. The layered immersion mechanism 6 includes an annular liquid reservoir 1 61, an annular liquid reservoir 2 62 and a high-temperature resistant infusion pump 63. The annular liquid reservoir 1 61 and the annular liquid reservoir 2 62 are both annular structural tank structures with a circular through hole in the center. The annular liquid reservoir 1 61 and the annular liquid reservoir 2 62 are arranged in a new form of longitudinal arrangement inside the main working kettle 1. The high-temperature resistant infusion pump 63 is divided into two groups and distributed on the fixed base 3. The injection ports of the annular liquid reservoir 1 61 and the annular liquid reservoir 2 62 are connected to the output port of the high-temperature resistant infusion pump 63 through a delivery pipe 64. The discharge ports of the liquid reservoir 1 61 and the annular liquid reservoir 2 62 are connected to the recovery tank 5 through a discharge pipe 65. The annular liquid reservoir 1 61 and the annular liquid reservoir 2 62 included in the layered immersion mechanism 6 are both annular tank structures, which are installed in the main working kettle 1 in the form of vertical distribution to maintain the coaxial arrangement between the annular liquid reservoir 1 61 and the annular liquid reservoir 2 62. A circular through hole is provided in the center of the annular liquid reservoir 1 61 and the annular liquid reservoir 2 62 inside the main working kettle 1.

The fixture with the copper solution attached is driven to be immersed in the annular liquid reservoir 62 by utilizing the steps when immersing in the annular liquid reservoir 61. The reciprocating rotation of the fixture is used to drive the copper solution attached to the surface to fully cooperate with the fixture to contact the coolant in the annular liquid reservoir 62.

The annular air supply pipe 74 is provided with a circumferentially distributed discharge port on the side facing the top wall of the main working kettle 1. The input port 74 is connected to the output end of the air pump. When the fixture blank follows the solid material lifting mechanism 8 and the metal liquid coating mechanism 9 to descend to the height of the annular liquid storage tank 62 in a reciprocating rotation state, the cooling and solidifying mechanism 7 installed inside the main working kettle 1 is turned on. The exhaust frame 71 included in the cooling and solidifying mechanism 7 is installed on the top surface of the main working kettle 1. The exhaust groove 72 opened therein allows the gas inside the main working kettle 1 to enter the exhaust frame 71. Then the air pump structure of the air collecting hopper 73 at the bottom of the main working kettle 1 is turned on, so that the annular air supply pipe 74 at the bottom of the air collecting hopper 73 begins to blow air toward the central through holes of the annular liquid storage tank 1 61 and the annular liquid storage tank 2 62, and the fixture blank with the copper solution on the outer surface is air-cooled, so that the copper solution is initially solidified on the fixture surface.
