Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, and in particular to a silver plating device for silver contacts. Background Technology

[0002] Silver plating equipment for silver contacts is a specialized device for plating silver layers onto the surfaces of electrical contact components such as relays, switches, and connectors. Through electrochemical deposition or chemical plating processes, a uniform and dense silver plating layer is formed on the surface of the metal substrate to improve the conductivity, oxidation resistance, and wear life of the contacts. Plating silver on the metal contact surfaces of electronic components such as relays, switches, and connectors improves the conductivity, wear resistance, and corrosion resistance of the contacts, ensuring the stability and reliability of electrical connections.

[0003] Silver plating equipment is a specialized device that deposits a silver layer on the surface of metal contacts using electrochemical or chemical methods. The core function of this equipment is to significantly improve the electrical, mechanical, and environmental performance of the contacts by depositing a silver layer. In high-frequency communication relays, silver-plated contacts can reduce signal transmission attenuation and ensure signal integrity. Utilizing the principle of electrolysis, silver ions are reduced from the plating solution to metallic silver and deposited on the surface of the silver contacts. In the electrolytic cell, the silver contacts act as the cathode, while the anode is typically a pure silver electrode or an insoluble anode. When current is applied, silver ions in the plating solution gain electrons at the cathode and are reduced to silver atoms, thus forming a silver plating layer on the surface of the silver contacts.

[0004] In existing technologies, a fixed height can lead to an unreasonable distance between the electrode and the workpiece for a long time. For example, if the anode and cathode are too close in electroplating, the high current density will accelerate the dissolution of the anode, shorten the life of the electrode, and increase the cost of replacing consumables. If the distance is too far, it will lead to increased energy consumption and waste of energy. When the equipment is processing large workpieces or when there are clamping errors, the non-adjustable height will cause mechanical collisions between the workpiece and the electrode, plating tank and other components, damaging the equipment. In electroplating, an unreasonable distance can also cause abnormal discharge and generate electric sparks, posing a safety hazard. Therefore, a silver contact silver plating equipment is proposed to solve the above problems. Utility Model Content

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the operation of a motor drives gear one to rotate. Gear one rotates through meshing with two of the gears two, and a fixed rod drives two other gears two to rotate. Through the meshing of gear two with a rack, a lifting function is achieved. Different sizes and shapes of silver contacts, such as small relay contacts and large contactor contacts, have different requirements for the silver plating process. The lifting function can flexibly adjust the equipment height to adapt to the loading and processing of various specifications of contacts, eliminating the need for frequent equipment changes or production line adjustments, reducing downtime, and improving production efficiency. In batch production, the equipment can load or unload multiple sets of contacts at once through lifting, shortening loading and unloading time.

[0024] 2. In this utility model, the cylinder operates to move the transmission plate, which in turn moves the connecting rod to move the fixing plate to achieve a fixed position. When the cylinder retracts, the spring resets the fixing plate. When producing different batches of contacts, the number of hooks on the hanger can be flexibly increased or decreased using quick-release hooks. For example, in small-batch precision contact production, some hooks can be removed to increase the spacing and prevent contact collisions; in large-batch production, the system can be fully loaded to improve equipment utilization and increase the flexibility of capacity adjustment. The quick-release hook design allows operators to avoid putting their hands deep into the plating tank when loading and unloading contacts, preventing direct contact with corrosive plating solutions.

A fixing block 2 10 is fixedly connected inside the square box 2 9, providing installation air and stability for the fixing block 2 10, ensuring stability during operation. A cylinder 11 is fixedly connected inside the fixing block 2 10, providing stability for the cylinder 11, preventing transmission shaking and deviation during operation, and ensuring the stability of power transmission. A transmission plate 12 is fixedly connected to the drive end of the cylinder 11. When the cylinder 11 operates, it drives the transmission plate 12 to move, transmitting power to the subsequent components through the transmission plate 12.

[0035] Inside each of the square boxes 2 and 9, two fixing plates 13 are fixedly connected. Square box 2 and 9 provide installation space for fixing plates 13, ensuring stability during the operation of subsequent components.

A mounting plate 20 is fixedly connected to the bottom end of the connecting plate 19, providing a fixed connection with the mounting plate 20. When moving, the connecting plate 19 drives the mounting plate 20 to move. Multiple hooks 21 are connected to the bottom end of the mounting plate 20, and the hooks 21 move when the mounting plate 20 moves. A solution tank 23 is fixedly connected to the front end of the support plate 22. The solution tank 23 is used to store solutions for silver plating silver-plated items.

[0037] The outer walls of the two fixed plates 18 are fixedly connected to the adjacent sides of the two connecting rods 14. When the connecting rods 14 move, they drive the fixed plates 18 to move synchronously, thus fixing and releasing the component.

The outer walls of the two connecting rods 14 are in contact with the inner wall of the transmission plate 12. When the transmission plate 12 moves, its inner wall contacts the outer wall of the connecting rods 14, causing the connecting rods 14 to move. The inner wall of the transmission plate 12 is at an angle, and the outer wall of the connecting rods 14 is at an angle. The outer wall of the transmission plate 12 is slidably connected to the inner wall of the square box 9. The square box 9 serves as a guide for the transmission plate 12 to prevent it from shifting during movement. The adjacent sides of the two fixing plates 18 are in contact with the outer wall of the connecting plate 19. The fixing plates 18 fix or loosen the connecting plate 19 through the operation of the components. The bottom of the square box 9 has a hole, which serves as a guide for the connecting plate 19.

[0038] Working principle: When the mounting plate 20 needs to be raised or lowered, the motor 3 on the inner wall of the square box 1 starts, driving the gear 4 on the drive end to rotate. When the gear 4 rotates, it drives two gears 6 fixed on the outer wall of the fixing rod 5 to rotate through their external teeth. When the gears 6 rotate, they drive the fixing rod 5 to rotate. The fixing rod 5 drives the other two gears 6 to rotate. The rotation of the other two gears 6 drives the rack 7 that meshes with them to rotate, converting the rotational motion into linear motion, which drives the connecting plate 8 fixed at the front end of the square box 1 to rise or fall. When it is necessary to switch between different product models, only the lifting height and process parameters need to be adjusted to quickly adapt to new production needs and enhance the flexibility of the production line.

[0039] When connecting plate 2 19 needs to be fixed, the cylinder 11 inside the square box 2 9 is activated, driving the transmission plate 12 at the drive end to slide inside the square box 2 9. When the transmission plate 12 moves, it pushes the connecting rod 14 sliding inside the fixing plate 1 13 to move. When the connecting rod 14 moves, it pushes the fixing plate 3 18 to move and fix the connecting plate 2 19, achieving the effect of fixation. When connecting plate 2 19 needs to be disassembled or replaced, the cylinder 11 drives the transmission plate 12 to retract, and the fixing plate 3 18 is reset through the connection of the spring 17 on the left side, achieving the effect of disassembly.
