Description

Technical Field

[0001] This utility model relates to the field of electroplating tool technology, specifically to a structure for a water-wetting conductive base. Background Technology

[0002] Electronic products play an important role in our daily lives and work, and heat spreaders are used in almost every industry, serving as the main functional center for most electronic products in the modern world.

[0003] In the production of vapor chambers, electroplating is one of the important processes. It is a process that uses electrolysis to deposit metal or alloy onto the surface of the workpiece to form a uniform, dense, and well-bonded metal layer.

[0004] Current conductive solutions for horizontal electroplating lines are primarily based on bottom friction conduction or top clamping conduction. However, as the industry develops and the products plated on horizontal electroplating lines become larger, the carrier tape has changed to a circulating flow mode. Consequently, bottom friction conduction is no longer suitable, and top clamping conduction is no longer adequate for field applications due to friction issues. Even after replacing the top clamping conduction mode with rolling friction conduction, frequent arcing can occur during the process due to the smaller contact area and the carrier tape not being a standard straight line.

[0005] A prior art patent with publication number CN213357794U discloses a solution comprising a clamping assembly, a reset assembly, a limiting assembly, and a sliding limiting plate. The clamping assembly includes an upper clamp and a lower clamp that are slidably connected, each with a horizontal clamping portion forming a clamping opening. The reset assembly includes elastic members fixed at both ends to the upper and lower clamps respectively. The limiting assembly includes a locking plate disposed on the lower clamp. When the locking plate is away from the lower clamp and receives the upper clamp, the clamp opens; when the locking plate is near the lower clamp and away from the upper clamp, the elastic member resets the clamp, closing it. The sliding limiting plate is disposed on the side of the lower clamp away from the upper clamp, and is used to achieve stable translation of the lower clamp. Automatic opening and closing of the horizontal electroplating clamp are achieved through an automatic opening assembly and an automatic closing assembly.

[0006] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0007] First, because the carrier tape used in the horizontal electroplating line for large-size products needs to be circulated online, the current bottom / top friction conductive mechanism will cause excessive frictional resistance due to the weight of the carrier tape and the product, making the material pulling mechanism unable to be used effectively, and will also cause wear on the bottom of the carrier tape, which cannot meet the requirements of on-site use.

[0008] Secondly, the top rolling friction mechanism has a sparking problem because the rollers are in line contact with the carrier belt, and the contact area is too small.

[0009] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a drip-wetting conductive seat structure to solve the problems of excessive frictional resistance caused by the weight of the carrier belt and product in traditional bottom / top friction conductive mechanisms, which renders the material pulling mechanism ineffective and causes wear on the bottom of the carrier belt; and the problem of arcing caused by the small contact area of ​​the roller relative to the carrier belt in the top rolling friction mechanism.

[0011] To achieve the above objectives, the present invention provides the following technical solution.

[0012] The drip-wetting conductive base structure includes a main conductive wheel and a secondary conductive wheel that are rotatably mounted side-by-side on a mounting body. The distance between the secondary conductive wheel and the main conductive wheel is adaptively adjusted by an elastic component. A carrier belt passage area is formed between the outer rings of the main conductive wheel and the outer rings of the secondary conductive wheel.

[0013] The upper surfaces of the main conductive wheel and the auxiliary conductive wheel are respectively provided with annular grooves on the same axis. The peripheral walls of the main conductive wheel and the auxiliary conductive wheel are provided with a number of water passage holes that connect the inner cavity of the annular groove to the outer ring of the main conductive wheel or the auxiliary conductive wheel.

[0014] As an optimized solution, the mounting body is hinged with a horizontally swingable mounting block by a pin, and the auxiliary conductive wheel is rotatably mounted on the mounting block.

[0015] As an optimized solution, the elastic component includes a horizontally arranged tension spring, one end of which is connected to the mounting block via a mounting post, and the other end of which is connected to the mounting body via a mounting post.

[0016] As an optimized solution, a secondary dripping needle tube is vertically fixed to the mounting block, and the outlet end of the secondary dripping needle tube is located above the annular groove of the secondary conductive wheel.

[0017] As an optimized solution, a main dripping needle tube is also fixedly connected to the mounting block, and the outlet end of the main dripping needle tube extends above the annular groove of the main conductive wheel.

[0018] As an optimized solution, the mounting body is vertically raised and lowered onto the mounting base plate via an adjustable structure.

[0019] As an optimized solution, the adjustment structure includes a height adjustment rod that is vertically threaded onto the mounting base plate, and the lower end of the height adjustment rod is rotatably mounted on the mounting body.

[0020] As an optimized solution, two guide posts are fixedly connected side by side on the mounting base plate, and the mounting body is provided with guide holes that match the guide posts.

[0021] As an optimized solution, the upper ends of the main conductive wheel and the secondary conductive wheel are respectively connected to conductive slip ring assemblies.

[0022] As an optimized solution, the mounting body is rotatably mounted with a top guide wheel for the carrier belt in the straight direction of the area through which the carrier belt passes.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This mechanism enables large-size continuous electroplating carrier tapes to operate without sliding friction, reducing precision loss due to tape wear caused by friction and slippage caused by excessive resistance.

[0025] This mechanism enables rolling conductivity on both sides while increasing the wetting of the carrier tape. After wetting, it effectively avoids arcing problems caused by the small contact area between the carrier tape and the conductive mechanism.

[0026] Fix the mounting base plate in the plating tank of the electroplating line, and adjust the overall position of the mechanism up and down by the height adjustment rod. Adjust the top guide wheel of the carrier belt to the top of the carrier belt. At this time, the main conductive wheel is in contact with one side of the carrier belt, and the auxiliary conductive wheel is pulled by the tension spring to drive the mounting block to drive the auxiliary conductive wheel to be in contact with the other side of the carrier belt, so as to realize the conductive function.

[0027] Both the main and auxiliary conductive wheels are machined with annular grooves, and water-permeable holes are evenly distributed at the bottom of the grooves. The dripping needle is fixed by the needle fixing hole opened on the mounting block. The inlet end of the needle is connected to the water inlet pipe, and the other side drips water onto the annular grooves of the main and auxiliary conductive wheels. The dripping water flows out through the water-permeable holes to the carrier belt to wet the carrier belt and prevent sparking. Attached Figure Description

Detailed Implementation

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0032] like Figure 1 As shown, the water-wetting conductive base structure includes a main conductive wheel 2 and a secondary conductive wheel 3 mounted side-by-side and rotatably on the mounting body 1. The secondary conductive wheel 3 adaptively adjusts its distance from the main conductive wheel 2 via an elastic component. A carrier belt passage area is formed between the outer ring of the main conductive wheel 2 and the outer ring of the secondary conductive wheel 3.

[0033] The upper surfaces of the main conductive wheel 2 and the auxiliary conductive wheel 3 are respectively provided with annular grooves 11 on the same axis. The peripheral walls of the main conductive wheel 2 and the auxiliary conductive wheel 3 are provided with a number of water passage holes 12 that connect the inner cavity of the annular grooves 11 to the outer ring of the main conductive wheel 2 or the auxiliary conductive wheel 3.

[0034] Mounting block 5, which is horizontally swingable, is hinged to mounting body 1 by pin 9, and auxiliary conductive wheel 3 is rotatably mounted on mounting block 5.

[0035] The elastic component includes a horizontally arranged tension spring 7, one end of which is connected to the mounting block 5 via a mounting post 8, and the other end of which is connected to the mounting body 1 via a mounting post 8.

[0036] A secondary dripping needle tube 6 is vertically fixed to the mounting block 5, and the outlet end of the secondary dripping needle tube 6 is located above the annular groove 11 of the secondary conductive wheel 3.

[0037] The mounting block 5 is also fixed with a main dripping needle tube 16. The outlet end of the main dripping needle tube 16 extends above the annular groove 11 of the main conductive wheel 2. Since the carrier belt is thin and the radial width of the reversing groove is greater than the swing distance of the auxiliary conductive wheel 3, the outlet end of the main dripping needle tube 16 will always be located above the annular groove 11.

[0038] The mounting body 1 is installed on the mounting base plate 13 by adjusting the structure to move vertically.

[0039] The adjustment structure includes a height adjustment rod 14 that is vertically threaded onto the mounting base plate 13, and the lower end of the height adjustment rod 14 is rotatably mounted on the mounting body 1.

[0040] Two guide posts 15 are fixedly connected side by side on the mounting base plate 13, and guide holes matching the guide posts 15 are opened on the mounting body 1.

[0041] The upper ends of the main conductive wheel 2 and the auxiliary conductive wheel 3 are respectively connected to conductive slip ring assemblies 10. The structure of the conductive slip ring assembly 10 is based on the basic principle of electroplating, which is well known, so it will not be elaborated here.

[0042] The mounting body 1 is rotatably mounted with a top guide wheel 4 for the carrier belt in the straight direction of the area through which the carrier belt passes.

[0043] The working principle of this device is as follows:

[0044] Fix the mounting base plate 13 in the plating tank of the electroplating line, and adjust the overall position of the mechanism up and down by the height adjustment rod 14. Adjust the top guide wheel 4 of the carrier belt to the top of the carrier belt. At this time, the main conductive wheel 2 is attached to one side of the carrier belt, and the auxiliary conductive wheel 3 is pulled by the tension spring 7 to the mounting block 5 to drive the auxiliary conductive wheel 3 to be attached to the other side of the carrier belt, so as to realize the conductive function.

[0045] Both the main conductive wheel 2 and the auxiliary conductive wheel 3 are machined with annular grooves 11. Water-permeable holes are evenly distributed at the bottom of the grooves. A dripping needle is fixed by a needle fixing hole on the mounting block 5. The inlet end of the needle is connected to the water inlet pipe, and the other side drips water onto the annular grooves 11 of the main conductive wheel 2 and the auxiliary conductive wheel 3. The dripping water flows out through the water-permeable holes onto the carrier belt to wet the carrier belt and prevent sparking.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
