[0018] A fully automatic electroplating method for a metal surface, the electroplating method comprising:

[0019] S1: The metal part to be electroplated is connected to the hook in a hanging manner, and the first electric motor is controlled to operate. During the operation, the output shaft of the first electric motor will exert torque on the upstream threaded connection column. Since the telescopic linkage shaft is stuck in the first concave groove at this stage, the sliding drive seat is supported by the telescopic linkage shaft and retracts to the depth of the first concave groove and applies pressure to the second support spring to deform it. The sliding drive seat will also be associated with the protrusion and generate extrusion force during this process. Under the action of the extrusion force, the toothed panel uses the movable adapter seat with the fixed adapter seat as the transfer medium, and performs lever movement based on this, thereby realizing the chain effect between the toothed panel and the telescopic linkage shaft. Therefore, the upstream threaded connection column will transmit the torque to the downstream threaded connection column through the midstream threaded connection column during the rapid rotation action. Under the combined effect of torque and thread bite force, the U-shaped threaded barrel will be able to perform linear movement on the upstream threaded connection column, the midstream threaded connection column and the downstream threaded connection column, thereby realizing the electroplating process of the metal part;

[0020] S2: When the hook is sent to the top of the electroplating liner, the first electric motor is controlled to operate. During the operation, the output shaft of the first electric motor will drive the threaded connection shaft to rotate in the threaded connection cylinder. Under the combined effect of torque and thread bite force, the midstream bridge seat and the metal piece to be electroplated on the hook can be driven downward until the metal piece to be electroplated is completely immersed in the electroplating solution for electroplating.

[0021] S3: During the electroplating process of the metal parts to be electroplated, the hydraulic cylinder is controlled to operate. During the operation of the hydraulic cylinder, its output shaft will drive the corresponding piston seat to perform piston movement in the high-pressure tank. Since the two piston seats are connected by two second linkage tooth plates and two linkage gears as the connecting medium between the two piston seats, it is possible to ensure that the two piston seats always maintain synchronous displacement movement, and the U-shaped structure tube and the drainage branch on the U-shaped structure tube can be used to continuously extract the steam generated by the heating of the electroplating inner tank. Similarly, after the steam is introduced into the interior of the high-pressure tank, it is further compressed and heated and then re-injected into the interior of the diversion box, and acts on the corresponding hooks through the diversion branch and the spiral tube on the diversion branch. When the pressurized steam flows through the spiral tube, due to the particularity of the spiral tube structure, a vortex will be formed around the metal parts to be driven;

[0022] S4: After the electroplating process of the metal parts is completed, the first electric motor is controlled to operate again to make the midstream bridge seat move upward. Under the action of the elastic member, the lifting seat moves upward, and the electroplating liquid gradually flows to the bottom of the lifting seat. The spiral tube gradually floats out of the liquid surface. At this time, the metal parts that have completed the electroplating process are dried by the hot air flow ejected from the spiral tube.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. After the electroplating process of the metal parts is completed, the first electric motor is controlled to operate again to make the midstream bridge seat move upward. Under the action of the elastic member, the lifting seat moves upward, and the electroplating solution gradually flows to the bottom of the lifting seat. The spiral tube gradually floats out of the liquid surface. At this time, the hot air flow ejected by the spiral tube dries the metal parts that have completed the electroplating process. The mechanical structure is used for kinetic energy conversion to achieve the drying of the metal parts that have completed the electroplating process, and the kinetic energy utilization rate of the equipment is high.

[0025] 2. Connect the metal part to be electroplated to the hook in a hanging manner, and control the operation of the first electric motor. During the operation, the output shaft of the first electric motor will exert torque on the upstream threaded connection column. Since the telescopic linkage shaft is stuck in the first concave groove at this stage, the sliding drive seat is supported by the telescopic linkage shaft and retracts to the depth of the first concave groove and applies pressure to the second support spring to deform it. The sliding drive seat will also be associated with the protrusion and generate extrusion force in this process. Under the action of the extrusion force, the toothed panel uses the movable adapter to use the fixed adapter as the transfer medium, and uses this as a basis for lever movement, thereby realizing the toothed panel. Due to the chain effect between the telescopic linkage shaft, the upstream threaded connecting column will transmit the torque to the downstream threaded connecting column through the midstream threaded connecting column during the rapid rotation action. Under the combined effect of torque and thread bite force, the U-shaped threaded cylinder will be able to make linear motion on the upstream threaded connecting column, the midstream threaded connecting column and the downstream threaded connecting column, thereby enabling assembly line production on the basis of realizing the electroplating process of metal parts, avoiding direct contact between the workers' bodies and the electroplated metal. The equipment is safe and reliable, and the electroplating efficiency is improved. The various mechanisms of the equipment are simple to disassemble, maintenance is convenient, and the production cost of the equipment is low.

[0026] 3. During the electroplating process of the metal parts to be electroplated, the hydraulic cylinder is controlled to operate. During the operation of the hydraulic cylinder, its output shaft will drive the corresponding piston seat to perform piston movement in the high-pressure tank. Since the two piston seats are connected by two second linkage tooth plates and two linkage gears, the two piston seats can always maintain synchronous displacement movement, and the U-shaped structure pipe and the drainage branch pipe on the U-shaped structure pipe can continuously extract the steam generated by the heating of the electroplating inner tank. Similarly, it can be seen that the steam is introduced into the interior of the high-pressure tank and is further compressed. The compressed and heated steam is re-injected into the interior of the diversion box, and acts on the corresponding hooks through the diversion branch pipe and the spiral tube on the diversion branch pipe. When the pressurized steam flows through the spiral tube, due to the particularity of the spiral tube structure, an eddy current is formed around the metal parts to be driven, and the uniformity of the plating solution is effectively guaranteed by driving the bottom layer of the electroplating solution upstream, thereby ensuring that the metal parts to be electroplated can fully react in the electroplating solution, and under the action of the eddy current, the metal parts to be electroplated are in a floating state, thereby achieving a comprehensive electroplating effect on the metal parts and ensuring the electroplating quality of the metal parts.

The coupling mechanism 6 includes a sliding drive seat 601, which is slidably connected in the first concave groove, and the side end surface of the sliding drive seat 601 is fixedly connected to the end surface inside the first concave groove through a second supporting spring 602. A toothed panel 603 is provided on the outer side of the sliding drive seat 601, and a movable adapter seat 605 is fixedly connected to the side of the toothed panel 603 facing away from the sliding drive seat 601. The movable adapter seat 605 is fixedly connected to the side of the toothed panel 603 facing away from the sliding drive seat 601. A fixed adapter seat 604 is rotatably connected, and the side of the fixed adapter seat 604 facing away from the movable adapter seat 605 is fixedly connected to the inner wall of the first concave groove.

The various mechanisms of the equipment are simple to disassemble and maintain, and the equipment production cost is low.

[0044] Specifically, Figure 4 As shown, the energy return mechanism 7 includes a high-pressure tank 701, the front end face of the high-pressure tank 701 is mounted on the rear end face of the working cabinet 101, and the interior of the high-pressure tank 701 is slidably connected to two piston seats 702, and the top of the high-pressure tank 701 corresponds to the position of the two piston seats 702 away from each other. The same U-shaped structure pipe 703 is connected, and the U-shaped structure pipe 703 is also connected to the bottom of the midstream bridge seat 201 through the drainage branch pipe 704.

[0045] The specific implementation mode of the present invention is as follows: during the electroplating process of the metal part to be electroplated, the hydraulic cylinder 707 is controlled to operate. During the operation of the hydraulic cylinder 707, its output shaft will drive the corresponding piston seat 702 to perform piston movement in the high-pressure tank 701. Since the two piston seats 702 are connected by two second linkage tooth plates 706 and two linkage gears 708 as the connecting medium between the two piston seats 702, it is possible to ensure that the two piston seats 702 always maintain synchronous displacement movement, and the U-shaped structure tube 703 and the drainage branch pipe 704 on the U-shaped structure tube 703 can be used to continuously extract the steam generated by the heating of the electroplating liner 102. Similarly, it can be known that the steam is introduced into the high-pressure tank 701. 01 is further compressed and heated before being re-injected into the diversion box 301, and acts on the corresponding hook 208 through the diversion branch pipe 303 and the spiral tube 304 on the diversion branch pipe 303. When the pressurized steam flows through the spiral tube 304, due to the particularity of the structure of the spiral tube 304, an eddy current is formed around the metal part to be driven, and the uniformity of the plating solution is effectively guaranteed by driving the bottom layer of the plating solution upstream, thereby ensuring that the metal part to be plated can fully react in the plating solution, and under the action of the eddy current, the metal part to be plated is in a floating state, thereby achieving a comprehensive electroplating effect on the metal part, thereby ensuring the electroplating quality of the metal part.

[0047] S1: The metal part to be electroplated is connected to the hook 208 in a hanging manner, and the first electric motor 204 is controlled to operate. During the operation, the output shaft of the first electric motor 204 will exert torque on the upstream threaded connection column 502. Since the telescopic linkage shaft 206 is stuck in the first concave groove at this stage, the sliding drive seat 601 is supported by the telescopic linkage shaft 206 and retracts to the depth of the first concave groove and applies pressure to the second support spring 602 to deform it. In this process, the sliding drive seat 601 will also be associated with the protrusion 606 and generate extrusion force. Under the action of the extrusion force, the toothed panel 603 uses the movable The fixed adapter 605 uses the fixed adapter 604 as the adapter medium, and performs lever movement based on this, realizing the linkage effect between the toothed panel 603 and the telescopic linkage shaft 206. Therefore, the upstream threaded connection column 502 will transmit the torque to the downstream threaded connection column 505 through the midstream threaded connection column 207 during the rapid rotation. Under the combined effect of the torque and the thread bite force, the U-shaped threaded cylinder 210 will be able to perform linear movement on the upstream threaded connection column 502, the midstream threaded connection column 207 and the downstream threaded connection column 505, thereby realizing the electroplating process of the metal parts.

[0048] S2: When the hook 208 is sent to the top of the electroplating liner 102, the first electric motor 204 is controlled to operate. During the operation, the output shaft of the first electric motor 204 will drive the threaded connection shaft 202 to rotate in the threaded connection cylinder 203. Under the combined effect of the torque and the thread bite force, the midstream bridge seat 201 and the metal piece to be electroplated on the hook 208 can be driven downward until the metal piece to be electroplated is completely immersed in the electroplating solution for electroplating.

[0049] S3: During the electroplating process of the metal part to be electroplated, the hydraulic cylinder 707 is controlled to operate. During the operation of the hydraulic cylinder 707, its output shaft will drive the corresponding piston seat 702 to perform piston movement in the high-pressure tank 701. Since the two piston seats 702 are connected by two second linkage tooth plates 706 and two linkage gears 708 as the connecting medium between the two piston seats 702, it is possible to ensure that the two piston seats 702 always maintain synchronous displacement movement, and the U-shaped structure tube 703 and the drainage branch pipe 704 on the U-shaped structure tube 703 can be used to continuously extract the steam generated by the heating of the electroplating liner 102. Similarly, it can be known that after the steam is introduced into the interior of the high-pressure tank 701, it is further compressed and heated and then re-injected into the interior of the diversion box 301, and acts on the corresponding hook 208 through the diversion branch pipe 303 and the spiral tube 304 on the diversion branch pipe 303. When the pressurized steam flows through the spiral tube 304, due to the particularity of the structure of the spiral tube 304, a vortex will be formed around the metal part to be driven;

[0050] S4: After the electroplating process of the metal parts is completed, the first electric motor 204 is controlled to operate again to make the midstream bridge seat 201 move upward. Under the action of the elastic member, the lifting seat 305 moves upward, and the electroplating liquid gradually flows to the bottom of the lifting seat 305. The spiral tube 304 gradually floats out of the liquid surface. At this time, the hot air flow ejected from the spiral tube 304 acts on the metal parts that have completed the electroplating process to dry the metal parts.

[0051] Working principle:

[0052] The metal part to be electroplated is connected to the hook 208 in a hanging manner to control the operation of the first electric motor 204. During the operation, the output shaft of the first electric motor 204 will exert torque on the upstream threaded connection column 502. Since the telescopic linkage shaft 206 is stuck in the first concave groove at this stage, the sliding drive seat 601 is supported by the telescopic linkage shaft 206 and retracts to the depth of the first concave groove and applies pressure to the second support spring 602 to deform it. During this process, the sliding drive seat 601 will also be associated with the protrusion 606 and generate an extrusion force. Under the action of the extrusion force, the toothed panel 603 uses the movable adapter seat 605 to use the fixed adapter seat 604 as the transfer medium, and uses this as a basis for lever movement to achieve The chain effect between the toothed panel 603 and the telescopic linkage shaft 206 is realized, so that the upstream threaded connection column 502 will transmit the torque to the downstream threaded connection column 505 through the midstream threaded connection column 207 during the rapid rotation action. Under the combined effect of the torque and the thread bite force, the U-shaped threaded cylinder 210 will be able to perform linear motion on the upstream threaded connection column 502, the midstream threaded connection column 207 and the downstream threaded connection column 505, thereby being able to perform assembly line production on the basis of realizing the electroplating process of metal parts, avoiding direct contact between the body of the staff and the electroplated metal, the equipment is safe and reliable, and the electroplating efficiency is improved. The various mechanisms of the equipment are simple to disassemble, maintenance is convenient, and the equipment production cost is low;

[0053] When the hook 208 is sent to the top of the electroplating liner 102, the first electric motor 204 is controlled to operate. During the operation, the output shaft of the first electric motor 204 will drive the threaded connection shaft 202 to rotate in the threaded connection cylinder 203. Under the combined effect of the torque and the thread bite force, the midstream bridge seat 201 and the metal piece to be electroplated on the hook 208 can be driven downward until the metal piece to be electroplated is completely immersed in the electroplating solution for electroplating.

[0054] During the electroplating process of the metal part to be electroplated, the hydraulic cylinder 707 is controlled to operate. During the operation of the hydraulic cylinder 707, its output shaft will drive the corresponding piston seat 702 to perform piston movement in the high-pressure tank 701. Since the two piston seats 702 are connected by two second linkage tooth plates 706 and two linkage gears 708 as the connecting medium between the two piston seats 702, it is possible to ensure that the two piston seats 702 always maintain synchronous displacement movements, and the U-shaped structure tube 703 and the drainage branch pipe 704 on the U-shaped structure tube 703 can be used to continuously extract the steam generated by the heating of the electroplating liner 102. Similarly, it can be known that the steam is introduced into the high-pressure tank 701. After further compression and temperature increase, the steam is re-injected into the shunt box 301, and acts on the corresponding hooks 208 through the shunt branch pipe 303 and the spiral tube 304 on the shunt branch pipe 303. When the pressurized steam flows through the spiral tube 304, due to the particularity of the structure of the spiral tube 304, an eddy current is formed around the metal piece to be driven, and the uniformity of the plating solution is effectively guaranteed by driving the upstream of the bottom layer of the electroplating solution, thereby ensuring that the metal piece to be electroplated can fully react in the electroplating solution, and the metal piece to be electroplated is in a floating state under the action of the eddy current, thereby achieving a comprehensive electroplating effect on the metal piece, and ensuring the electroplating quality of the metal piece;

[0055] After the electroplating process of the metal parts is completed, the first electric motor 204 is controlled again to operate to make the midstream bridge seat 201 move upward. Under the action of the elastic member, the lifting seat 305 moves upward, and the plating liquid gradually flows to the bottom of the lifting seat 305. The spiral tube 304 gradually floats out of the liquid surface. At this time, the metal parts that have completed the electroplating process are dried under the action of the hot air flow ejected by the spiral tube 304. The mechanical structure is used to convert kinetic energy to achieve the drying of the metal parts that have completed the electroplating process, and the kinetic energy utilization rate of the equipment is high.
