Description

Technical Field

[0001] This utility model relates to a rotatable and pressable conductive base that is scratch-resistant, belonging to the technical field of electroplating equipment. Background Technology

[0002] In the electroplating production field, vertical feeding equipment is widely used due to its high space utilization and strong process adaptability. In existing technologies, vertical feeding systems mostly employ a left-right clamping conveyor structure, where the conveying and electrical conductivity are achieved by fixing the edges of the conveyor belt through clamping mechanisms on both sides. However, this structure has the following significant drawbacks:

[0003] 1. Difficulty in adjusting belt tension: When the belt tension changes due to thermal expansion and contraction or speed fluctuations during the production process, it is impossible to adjust the tension, which can easily lead to the belt becoming loose and floating or being overstretched and deformed, seriously affecting product yield and equipment stability.

[0004] 2. High risk of surface scratches on the strip: The clamping mechanisms on both sides are in direct contact with the edge of the strip. During high-speed feeding, the metal clamps and the strip experience continuous friction and scraping, resulting in scratches, plating peeling, or indentations on the upper and lower surface edges of the strip. This problem is particularly prominent in thin, high-precision electronic electroplating products, causing a large number of defective products to be lost.

[0005] 3. Asynchronous movement of the conductive roller and the pressure roller: In existing designs, the conductive roller (responsible for current conduction) and the PP pressure roller (responsible for material strip positioning) are usually controlled by independent drive systems. Due to mechanical transmission errors or control timing deviations, the linear speeds of the two rollers often become inconsistent, causing the material strip to slip between the rollers or local stress concentration, which exacerbates surface damage and causes fluctuations in electroplating current, affecting the uniformity of the coating.

[0006] In summary, the existing clamp-type feeding structure has systematic deficiencies in terms of strip tension adjustment, surface protection, and motion synchronization. There is an urgent need for an innovative solution that can adjust strip tension, avoid surface contact damage, and ensure synchronous operation of the rollers in order to improve the quality and efficiency of electroplating production. Utility Model Content

[0007] The purpose of this invention is to provide a rotatable conductive seat that prevents material from being scratched and can be pressed. This conductive seat can adjust the tension of the material strip, avoid surface contact damage, and ensure synchronous operation of the rollers, thereby improving the quality and efficiency of electroplating production.

[0008] To achieve this objective, the present invention employs the following technical solution:

[0009] This utility model provides a rotatable and pressure-operated conductive base for preventing material scratches, including a base, a lower plate connected to the base, a rotatable rotating plate connected to the lower plate, a vertical plate fixedly connected to the rotating plate, a cover plate fixedly connected to the vertical plate, a rotatable pressure roller and a conductive roller disposed between the cover plate and the rotating plate, a material strip disposed between the pressure roller and the conductive roller, a mercury slip ring connected to the conductive roller, a first gear connected below the conductive roller, a second gear connected below the roller, the first gear and the second gear meshing and disposed in a receiving groove opened in the lower plate and the base.

[0010] In one embodiment of this utility model, the rotating plate has a plurality of arc-shaped holes, and a second bolt is provided in the arc-shaped holes. The rotating plate is connected to the lower plate by the second bolt.

[0011] In one embodiment of this utility model, the number of arc-shaped holes is four, and the four arc-shaped holes are disposed at the four corners of the rotating plate.

[0012] In one embodiment of this utility model, leveling holes are provided at the four corners of the rotating plate, and set screws are installed in the leveling holes.

[0013] In one embodiment of this utility model, the lower plate has a plurality of elongated holes, and a first bolt is disposed in each of the elongated holes; the base has a plurality of nut holes, each of the nut holes corresponding to one of the elongated holes, and a nut is installed in each of the nut holes, and the first bolt is threadedly connected to the nut.

[0014] In one embodiment of this utility model, the nut hole is hexagonal, and the nut is a hexagonal nut.

[0015] In one embodiment of this utility model, the pressure roller and the conductive roller are connected to the cover plate and the rotating plate through bearings.

[0016] In one embodiment of this utility model, the bearing is a ceramic bearing.

[0017] In one embodiment of this utility model, the first gear and the second gear are made of polyethylene.

[0018] In one embodiment of this utility model, the pressure roller is made of polypropylene.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model provides a rotatable, anti-scratch conductive seat, which has a mercury slip ring connected to the conductive roller. The mercury slip ring is a rotary connector used for conducting current or signals. When the conductive seat is working, the current flows from the power supply through the mercury slip ring and through the conductive roller. When the material strip passes through the conductive seat, it contacts the conductive roller, and the current is ultimately conducted to the material strip. During material feeding, the rotation angle of the rotating plate can be adjusted by adjusting the position of the second bolt in the arc-shaped hole, thereby easily adjusting the tension of the material strip and preventing the material strip from becoming loose and drifting or excessively stretched and deformed, which would seriously affect the product yield and equipment stability. Because a first gear is connected below the conductive roller and a second gear is connected below the pressure roller, an external drive device rotates one of the gears. With the meshing of the first and second gears and the cooperation of bearings, the conductive roller and pressure roller rotate synchronously relative to each other, ensuring they move at the same linear speed. This prevents the strip from slipping between the rollers or experiencing localized stress concentration, which could exacerbate surface damage. It also prevents fluctuations in the electroplating current that could affect the uniformity of the plating layer, allowing the strip to move smoothly and preventing scratches or abrasions on the strip surface. Furthermore, by adjusting the position of the first bolt within the elongated hole, the position of the lower plate on the base can be adjusted to match the strip's feeding position. A hexagonal nut is installed in the nut hole of the base, and the lower plate and the rotating plate connected to it are locked by the threaded connection between the first bolt and the hexagonal nut, eliminating the need for a separate tightening device and preventing stripping of the base. Therefore, this conductive base can adjust the strip tension, prevent surface contact damage, and ensure synchronous operation of the rollers, thereby improving the quality and efficiency of electroplating production.

[0029] like Figures 1-4 As shown, this utility model provides a rotatable and pressable conductive base for preventing material scratches, including a base 1, a lower plate 2 connected to the base 1, a rotatable rotating plate 3 connected to the lower plate 2, a vertical plate 7 fixedly connected to the rotating plate 3, a cover plate 5 fixedly connected to the vertical plate 7, a rotatable pressing roller 4 and a conductive roller 8 arranged between the cover plate 5 and the rotating plate 3, a material strip 9 arranged between the pressing roller 4 and the conductive roller 8, a mercury slip ring 6 connected to the conductive roller 8, a first gear 11 connected below the conductive roller 8, and a second gear 12 connected below the roller 4. The first gear 11 and the second gear 12 mesh and are arranged in a receiving groove 18 opened in the lower plate 2 and the base 1.

[0030] In some embodiments, the rotating plate 3 has a plurality of arc-shaped holes 17, and a second bolt 16 is provided in the arc-shaped holes 17. The rotating plate 3 is connected to the lower plate 2 by the second bolt 16.

[0031] Optionally, the number of arc-shaped holes 17 is four, and the four arc-shaped holes 17 are disposed at the four corners of the rotating plate 3.

[0032] In some embodiments, leveling holes 19 are provided at the four corners of the rotating plate 3, and set screws are installed in the leveling holes 19. In this embodiment, by installing set screws in the leveling holes 19 at the four corners of the rotating plate 3, the rotating plate 3 is leveled to ensure the horizontality of the rotating plate 3, thereby ensuring the perpendicularity of the conductive roller 8 and the pressure roller 4, and thus ensuring the smooth feeding of the material belt 9.

[0033] In some embodiments, the lower plate 2 has a plurality of elongated holes 14, and a first bolt 13 is disposed in the elongated holes 14; the base 1 has a plurality of nut holes 15, and the plurality of nut holes 15 correspond one-to-one with the plurality of elongated holes 14, and a nut is installed in the nut hole 15, and the first bolt 13 is threadedly connected to the nut.

[0034] Optionally, the nut hole 15 is hexagonal, and the nut is a hexagonal nut.

[0035] In some embodiments, the pressure roller 4 and the conductive roller 8 are connected to the cover plate 5 and the rotating plate 3 via bearings 10.

[0036] Optionally, the bearing 10 is a ceramic bearing. Ceramic bearings are high-performance bearings with excellent wear resistance, high temperature resistance, and corrosion resistance, enabling them to maintain good performance in many harsh environments.

[0037] Optionally, the first gear 11 and the second gear 12 are made of polyethylene (PE), which has the characteristics of being lightweight, wear-resistant, impact-resistant and self-lubricating.

[0038] Optionally, the pressure roller 4 is made of polypropylene (PP).

[0039] In summary, this utility model provides a rotatable, anti-scratch conductive seat with a mercury slip ring 6 connected to the conductive roller 8. The mercury slip ring 6 is a rotary connector used for conducting current or signals. When the conductive seat is working, the current flows from the power supply through the mercury slip ring 6 and then through the conductive roller 8. The material strip 9 contacts the conductive roller 8 when passing through the conductive seat, ultimately allowing the current to be conducted onto the material strip 9. During material feeding, the rotation angle of the rotating plate 3 can be adjusted by adjusting the position of the second bolt 16 within the arc-shaped hole 17, thereby conveniently adjusting the tension of the material strip 9 and preventing the material strip 9 from becoming loose and swaying or excessively stretched and deformed, which would seriously affect product yield and equipment stability. Because a first gear 11 is connected below the conductive roller 8 and a second gear 12 is connected below the pressure roller 4, an external drive device rotates one of the gears. Under the meshing of the first gear 11 and the second gear 12, and with the cooperation of the bearing 10, the conductive roller 8 and the pressure roller 4 rotate synchronously relative to each other, so that the conductive roller 8 and the pressure roller 4 move at the same linear speed. This avoids slippage or local stress concentration of the material strip 9 between the rollers, which would aggravate surface damage. It also avoids fluctuations in the electroplating current that would affect the uniformity of the plating layer, allowing the material strip 9 to move smoothly and preventing the surface of the material strip 9 from being scratched or abraded. In addition, by adjusting the position of the first bolt 13 in the elongated hole 14, the position of the lower plate 2 on the base 1 can be adjusted to match the feeding position of the material strip 9. Furthermore, a hexagonal nut is provided in the nut hole 15 of the base 1. The lower plate 2 and the rotating plate 3 connected to the lower plate 2 can be locked by the threaded connection between the first bolt 13 and the hexagonal nut, thus eliminating the need for an additional tightening device and preventing the base 1 from slipping. Therefore, the conductive base can adjust the tension of the strip, avoid surface contact damage, and ensure synchronous operation of the rollers, thereby improving the quality and efficiency of electroplating production.

[0040] The scope of protection of this utility model is not limited to the above embodiments. Any modifications, equivalent substitutions, and improvements that can be made by those skilled in the art within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
