[0002] In the production and processing of network transformers, tin plating of the pins is a key process to ensure the product's conductivity and oxidation resistance.

[0003] The inventors have discovered that at least the following problems remain unsolved in the existing technology: the existing tin plating equipment lacks an effective heat insulation and protection design, and the high temperature generated during the tin plating operation is directly conducted to precision components such as cylinders and robots, accelerating component aging and reducing equipment lifespan; moreover, the tin plating liquid level detection is set up separately from the operation mechanism, resulting in poor process connection and uneven plating thickness due to liquid level height errors.

[0004] Secondly, the workpiece positioning and adjustment flexibility is poor, and the clamping mechanism has a limited range of adaptability. When dealing with network transformers of different specifications, tooling needs to be changed frequently, which increases the complexity of operation and production costs.

[0005] Therefore, we propose a device for tin plating network transformer pins, which can solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1 to 3 A tin plating device for network transformer pins includes a frame 1, a robotic tin plating mechanism 10, and a tin plating head 20. The robotic tin plating mechanism 10 is fixedly mounted on the upper surface of the frame 1. The tin plating head 20 is detachably connected to the end of the robotic tin plating mechanism 10 away from the frame 1, and the robotic tin plating mechanism 10 drives the tin plating head 20 to move in multiple directions. The frame 1 provides a stable support foundation for the device. The robotic tin plating mechanism 10 is fixed to the top of the frame 1 and serves as the power drive core. Through its multi-degree-of-freedom motion characteristics, it drives the detachably connected tin plating head 20 to achieve multi-directional movement in three-dimensional space, thereby meeting the tin plating requirements of network transformer pins at different positions and angles. The detachable design of the tin plating head 20 facilitates later maintenance and replacement, improving the versatility and service life of the device.

[0021] Furthermore, the robotic tin plating mechanism 10 includes a robotic arm 101 and a robotic mounting plate 102 for fixing the robotic arm 101. The bottom side of the robotic mounting plate 102 is fixedly connected to the upper surface of the large plate connecting plate 103 via four sets of vertical mounting side plates 104. The large plate connecting plate 103 is detachably mounted on the upper surface of the frame 1 by bolts. Through the vertical support of the mounting side plates 104 and the load-bearing distribution of the large plate connecting plate 103, the overall rigidity of the robotic tin plating mechanism 10 is improved, effectively preventing the swaying of the robotic arm 101 during movement. The bolt-detachable large plate connecting plate 103 facilitates the disassembly, assembly, and position adjustment of the robotic tin plating mechanism 10, adapting to the installation requirements of different specifications of the frame 1.

[0022] Furthermore, the tin plating head 20 includes a robot connecting plate 214 and a mounting base 212. The tin plating head 20 is fixedly connected to the free end of the robot arm 101 via the robot connecting plate 214, which is welded to the middle of the upper surface of the mounting base 212. The tin plating head 20 is rigidly connected to the free end of the robot arm 101 via the robot connecting plate 214, and the robot connecting plate 214 is welded to the middle of the upper surface of the mounting base 212, ensuring that the motion force of the robot arm 101 can be accurately transmitted to the mounting base 212, thereby driving the entire tin plating head 20 to move synchronously.

[0023] Furthermore, gripper cylinders 201 are fixedly connected to both sides of the lower surface of the mounting base 212. Product grippers 203 are horizontally arranged on the bottom side of each gripper cylinder 201. The two sets of gripper cylinders 201 on the bottom side of the mounting base 212 are fixedly connected to both sides of the product grippers 203 via a heat-insulating mounting plate 202. The heat-insulating mounting plate 202 is fixed to the outside of the robot connecting plate 214, serving both as the mounting carrier for the gripper cylinders 201 and preventing the high temperature during tin plating from being conducted to the robot connecting plate 214 and the robot arm 101 through the heat-insulating material. The gripper cylinders 201 drive the product grippers 203 to open and close to hold the network transformer workpiece. The heat-insulating mounting plate 202 effectively isolates the high temperature of tin plating from the thermal impact on the cylinders and robot components, extending the service life of precision components. The cooperative design of the product grippers 203 and the protective block 204 ensures the stability of workpiece clamping.

[0024] Furthermore, a multi-position fixing cylinder 213 is fixedly connected to the middle of the mounting base 212. The telescopic end of the multi-position fixing cylinder 213 is fixedly connected to the middle of the upper surface of the magnetic pressure strip 207. A high-temperature resistant magnetic groove 208 is provided between the two sets of product grippers 203. The magnetic pressure strip 207 is horizontally placed inside the high-temperature resistant magnetic groove 208. A protective block 204 is fixedly installed on one side of the lower surface of the mounting base 212. A flange linear bearing 205 and a guide shaft 206 are provided on one side of the protective block 204. The flange linear bearing 205 embedded inside the mounting base 212 provides vertical sliding support for the guide shaft 206, ensuring the smooth movement of the guide shaft 206. The multi-position fixing cylinder 213 drives the magnetic pressure strip 207 to extend and retract within the high-temperature resistant magnetic groove 208, realizing the position adjustment of the magnetic component.

[0025] Furthermore, a cylinder mounting plate 211 is fixedly connected to one end of the mounting base 212 where the protective block 204 is mounted. A three-axis cylinder 210 is fixedly connected to the bottom side of the cylinder mounting plate 211, and a tin surface probe 209 is fixedly connected to the telescopic end of the three-axis cylinder 210. The cylinder mounting plate 211 is fixed to the end of the mounting base 212, providing a stable mounting reference for the three-axis cylinder 210. The three-axis cylinder 210 drives the tin surface probe 209 to move vertically through its telescopic end, achieving precise detection of the height and position of the tin plating liquid, providing a basis for parameter adjustment in subsequent tin plating operations.
