Technical Field
[0001] This invention relates to the field of gold plating technology for small soft metal parts, specifically to gold plating equipment for small parts. Background Technology
[0002] Small parts are typically plated with gold using small barrel plating equipment. Before plating, conductive steel balls are placed in the plating cage. Then, the small parts to be plated are placed in. This type of plating has two major drawbacks: 1. The steel balls absorb a large amount of gold after plating, leading to a significant increase in plating costs; 2. The soft metals collide with each other during the rolling process, causing scratches, edge collapse, and other defects, resulting in low yield and significantly increased costs.
[0003] To address the aforementioned issues, a gold plating device for small parts has been designed. Summary of the Invention
[0004] The purpose of this invention is to provide a gold plating device for small parts to solve the problems mentioned in the background art.

The pitch circle diameter of the auxiliary gear connected to the output shaft of the barrel plating host is smaller than the pitch circle diameter of the other two auxiliary gears.
[0016] As a further embodiment of the present invention: the sealing cover, connecting shaft, rotating rod, sealing base, chuck fixing seat, rotating shaft, gear, grid cover plate and grid mesh plate are all made of Teflon material.

Detailed Implementation
[0028] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example 1
[0030] Please see Figure 1-7In this embodiment of the invention, the small parts gold plating equipment includes a barrel plating host 36, a conductive component, a connecting component, and a limiting component. The barrel plating host 36 is mounted on one side of the head of a mounting frame 35. The bottom of the mounting frame 35 is symmetrically provided with two support base rods 33 to improve the stability of the mounting frame 35 during use. The conductive component, used to continuously conduct electricity into the limiting component, includes a sealing base 28 and a sealing cover 32 detachably connected to the sealing base 28. A connecting shaft 22 is provided through the middle of the sealing base 28 and the sealing cover 32.

The inner cavity of the sealing base 28 is provided with a fixed conductive contact 30 connected to the movable conductive contact 26. The fixed conductive contact 30 is provided with a fixed wire 29 for connecting to the barrel plating host 36. Through the coordinated use of the conductive component, the connecting component, and the limiting component, the loss of gold plating material can be reduced, the defects caused by product collisions during the electroplating process can be reduced, the yield of electroplated products can be improved, and the electroplating cost can be reduced.
[0031] The connecting assembly, used to mount the limiting assembly on the mounting frame 35, includes a chuck fixing seat 20 and a gear 19. The chuck fixing seat 20 is fixedly connected to the gear 19 via a sealing base 28. The gear 19 is meshed with a gear set 34 located on the side wall of the mounting frame 35 away from the barrel plating host 36. After the barrel plating host 36 is started, the gear set 34 will drive the limiting assembly to rotate through the connecting assembly, ensuring that each product is electroplated evenly and will not collide with each other, thereby improving electroplating efficiency and yield.
[0032] The limiting component is used to fix the position of the soft metal part 13. It includes a grid plate 12 and a grid cover plate 11 detachably connected to the grid plate 12. Both the grid cover plate 11 and the grid plate 12 are provided with conductive copper wires 14 that have a conductive function. The grid plate 12 is provided with a plurality of placement grids 16 that limit the position of the soft metal part 13.
[0033] The bottom of the grid plate 12 is provided with a connecting rod 17 for connecting to the chuck fixing seat 20, and the chuck fixing seat 20 is provided with three slots 21 for connecting to the connecting rod 17 in a circular array along the upper edge of the chuck fixing seat 20.
[0034] A PU spring 27 is provided at the connection between the chuck fixing seat 20 and the inner wall of the sealing base 28.
[0035] The grid cover plate 11 and the grid mesh plate 12 are connected and fixed by multiple plastic screws 15. The grid mesh plate 12 is provided with connecting posts that connect to the plastic screws 15. The connecting posts are provided with screw holes. After multiple soft metal parts 13 are placed into the placement grids 16 on the grid mesh plate 12, the grid cover plate 11 and the grid mesh plate 12 are connected and fixed by the plastic screws 15, thus completing the fixation of the position of the soft metal parts 13. The conductive copper wires 14 on each grid mesh plate 12 and grid cover plate 11 directly conduct electricity to the soft metal parts 13. The installation is simple and the disassembly method is easy, which greatly improves work efficiency and user experience. The area of the conductive copper wires 14 is smaller than that of the steel balls, thus reducing the amount of gold lost.
[0036] The chuck mounting base 20, the rotating shaft 18, and the gear 19 are all provided with through holes to facilitate the passage of the rotating wire 31.
[0037] The limiting components are provided in three sets, and the ends of the three sets of limiting components away from the chuck fixing seat 20 are connected by a buckle cover 37.
[0038] The gear set 34 is connected to the output shaft end of the barrel plating host 36. The gear set 34 includes three meshing auxiliary gears. The pitch circle diameter of the auxiliary gear connected to the output shaft of the barrel plating host 36 is smaller than the pitch circle diameter of the other two auxiliary gears.
[0039] The sealing cover 32, connecting shaft 22, rotating rod 23, sealing base 28, chuck fixing seat 20, rotating shaft 18, gear 19, grid cover plate 11 and grid mesh plate 12 are all made of Teflon material, which effectively prevents electrolyte from corroding the moving conductive contacts.
[0040] Example 2

[0042] The working principle of this invention is as follows: In use, multiple soft metal parts 13 are placed into the placement grids 16 on the grid plate 12, and then the grid cover plate 11 and the grid plate 12 are connected and fixed by plastic screws 15, thus fixing the position of the soft metal parts 13. Conductive copper wires 14 on each grid plate 12 and grid cover plate 11 directly conduct electricity to the soft metal parts 13. The area of the conductive copper wires 14 is smaller than that of the steel balls, reducing the amount of gold lost. After starting the barrel plating host 36, the gear set 34 drives the limiting component to rotate through the connecting component, ensuring that each product is electroplated evenly and without collision, thereby improving electroplating efficiency and yield.
[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
