Description

Technical Field

[0001] This application relates to the field of electroplating technology, specifically to an electroplating rack. Background Technology

[0002] Electroplating is a key process that uses the principle of electrolysis to deposit a metal film on the surface of metal or other materials. It is widely used in industries such as electronics, automobiles, and hardware. With the increasing demand for high-precision and high-efficiency production, electroplating racks, as core equipment that carries workpieces and conducts current, directly determine the electroplating quality and production efficiency.

[0003] Traditional electroplating fixtures rely on hooks to hold the workpiece at its edge or springs to clamp it in place. Hooks are simple and inexpensive, but the clamping force depends entirely on manual operation. They are prone to falling off due to hook wear or workpiece movement, especially for irregularly shaped or small workpieces. Springs provide better initial clamping, but after long-term use, the springs are prone to fatigue failure due to high-frequency opening and closing, resulting in a decrease in clamping force.

[0004] To address the aforementioned issues, this application provides an electroplating fixture that, through an innovative workpiece clamping mechanism design, achieves rapid loading, unloading, and stable fixation of workpieces while ensuring electrical conductivity reliability, effectively solving the technical shortcomings of existing fixtures in the clamping process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an electroplating fixture that offers the advantage of stable fixation and solves the problem of workpieces easily falling off.

[0006] To achieve the above objectives, this application provides the following technical solution: an electroplating hanger, comprising a frame, multiple sets of first hooks, multiple sets of second hooks and connecting plates, and multiple sets of connecting buckles. The multiple sets of connecting buckles are disposed on the top of the frame, and the connecting plates are disposed on the inner wall of the frame. Sliding buckles are slidably connected to both sides of the frame. A support frame is fixedly connected to the opposite faces of two sets of sliding buckles. A first rotating shaft is disposed on the opposite inner walls of the support frame. A lead screw is fixedly connected to the opposite ends of the two sets of first rotating shafts. Multiple threaded plates are threaded onto the surface of the lead screw. Multiple second hooks are respectively disposed on both sides of the multiple threaded plates. Multiple sets of first hooks are respectively disposed on both sides of the support frame. A worm gear is fixedly connected to the other end of the first rotating shaft. A damping bearing is fixedly inserted through the top of the support frame. A second rotating shaft is rotatably connected within the damping bearing. A worm is fixedly connected to the other end of the second rotating shaft, and the worm meshes with the worm gear. A knob is fixedly connected to the top of the second rotating shaft. With the above scheme, rotating the knob drives the second rotating shaft and worm gear to rotate. Through the meshing transmission of the worm gear, the first rotating shaft and lead screw are driven to rotate, causing the threaded plate to move along the axial direction of the lead screw. Adjusting the distance between the second hook and the first hook allows for clamping and fixing of workpieces of different sizes, improving the clamping stability of the workpiece. The sliding buckle is fixed to the screw holes on both sides of the frame through the first stud, and the position of the support frame can be adjusted along the frame to facilitate the adjustment of the workpiece height.

[0007] Furthermore, the top of each of the connecting buckles near both sides is movably connected to a movable frame via a hinge. Each movable frame is fixedly connected to one side of the connecting buckle with a mounting plate. The top of each of the two sets of mounting plates is provided with a connecting groove, and a second stud is threaded into the connecting groove. A nut is provided on the surface of the second stud. Multiple sets of movable frames are fixedly connected via guide plates.

[0008] The above solution allows the movable frame, which is hinged, to move. The movable frame and the connecting buckle can be fixedly installed with the help of the mounting plate, connecting groove, and second stud to prevent it from falling off when suspended.

[0009] Furthermore, multiple sets of screw holes are provided on both sides of the frame, and the two sets of sliding buckles are fixedly installed on the surface of the frame through the first stud and the screw holes.

[0010] With the above solution, by opening screw holes and setting the first stud, the sliding buckle can be fixed when it moves to a suitable height.

[0011] Furthermore, each of the support frames has a slot at its top, and a conductive arm is fixedly installed at the bottom of the inner wall of the frame by bolts. The conductive arm is slidably connected in the slot and is in contact with the support frame.

[0012] The above solution, with its combined design of the slot and conductive arm, ensures that the current is stably conducted through the conductive arm to the support frame and hook, facilitating electroplating.

[0013] Furthermore, multiple through slots are provided on both sides of the support frame, and multiple second hooks are slidably connected in the multiple through slots respectively.

[0014] The above scheme provides a sliding track for the second hook, which, in conjunction with the movement of the threaded plate along the screw, allows the second hook to move within the through groove, thus limiting the movement of the threaded plate and the second hook.

[0015] Furthermore, a base plate is fixedly connected to the bottom of the frame, and the top of the base plate is fixedly connected to the same reinforcing plate on one side of the frame.

[0016] The above solution, by setting up reinforcing plates and a base plate, allows the triangular support structure to prevent the frame from tilting due to gravity.

[0017] Furthermore, the bottom of the support frame has an opening, the surfaces of the support frame, the sliding buckle and the frame are coated with a corrosion-resistant coating, the contact surface of the conductive arm and the slot is plated with a copper conductive layer, and the surfaces of the first hook and the second hook are plated with a nickel-phosphorus alloy coating.

[0018] Through the above scheme, the corrosion-resistant coating can resist the chemical corrosion of the electroplating solution, the copper conductive layer has high conductivity and anti-oxidation properties, and by setting an opening, the electrolyte can be discharged from the opening when the frame is removed from the electrolyte pool.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects: This electroplating fixture, when the knob is turned, drives the second rotating shaft and worm gear to rotate. Through the meshing transmission of the worm gear and worm wheel, it drives the first rotating shaft and lead screw to rotate, causing the threaded plate to move along the axial direction of the lead screw. Adjusting the distance between the second hook and the first hook allows for clamping and fixing of workpieces of different sizes, improving the clamping stability of the workpiece. The sliding buckle is fixed to the screw holes on both sides of the frame through the first stud, and the position of the support frame can be adjusted along the frame to facilitate the adjustment of the workpiece height.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of an electroplating fixture includes a frame 1, multiple sets of first hooks 13, multiple sets of second hooks 15, a connecting plate 42, and multiple sets of connecting buckles 3. The multiple sets of connecting buckles 3 are disposed on the top of the frame 1, and the connecting plate 42 is disposed on the inner wall of the frame 1. Sliding buckles 7 are slidably connected to both sides of the frame 1. The opposite faces of two sets of sliding buckles 7 are fixedly connected to the same support frame 8. The opposite inner walls of the support frame 8 are each provided with a first rotating shaft 22. The opposite ends of the two sets of first rotating shafts 22 are fixedly connected to the same lead screw 21. Multiple threaded plates 20 are threaded onto the surface of the lead screw 21. Multiple second hooks 15 are respectively disposed on both sides of the multiple threaded plates 20. Multiple sets of first hooks 13 are respectively disposed on both sides of the support frame 8. A worm gear 23 is fixedly connected to the other end of the first rotating shaft 22. A damping bearing 11 is fixedly installed at the top of the support frame 8. A second rotating shaft 10 is rotatably connected inside the damping bearing 11. A worm 24 is fixedly connected to the other end of the second rotating shaft 10. The worm 24 meshes with a worm wheel 23. A knob 9 is fixedly connected to the top of the second rotating shaft 10. Rotating the knob 9 drives the second rotating shaft 10 and the worm 24 to rotate. Through the meshing transmission of the worm wheel 23 and the worm 24, the first rotating shaft 22 and the lead screw 21 are driven to rotate, causing the threaded plate 20 to move axially along the lead screw 21. Adjusting the distance between the second hook 15 and the first hook 13 allows for clamping and fixing of workpieces of different sizes, improving the clamping stability of the workpiece. The sliding buckle 7 is fixed to the screw holes 5 on both sides of the frame 1 through the first stud 6. It can slide along the frame 1 to adjust the position of the support frame 8, making it easy to adjust the height of the workpiece.

[0024] Please see Figure 1 , Figure 2 and Figure 3Near the two sides, the top of the connecting buckle 3 is movably connected to the movable frame 25 via hinges. The movable frame 25 and one side of the connecting buckle 3 are fixedly connected to the mounting plate 26. The top of both mounting plates 26 has a connecting groove 28, with a second stud 27 threaded into the connecting groove 28. A nut is provided on the surface of the second stud 27. Multiple movable frames 25 are fixedly connected via guide plates. Multiple screw holes 5 are provided on both sides of the frame 1. Two sets of sliding buckles 7 are fixedly installed on the surface of the frame 1 via the first stud 6 and the screw holes 5. The top of the support frame 8 has a slot 17. The bottom of the inner wall of the frame 1 is fixed with bolts. Equipped with a conductive arm 16, which is slidably connected in a slot 17, the conductive arm 16 contacts the support frame 8. The movable frame 25, which is hinged, can be moved. The movable frame 25 and the connecting buckle 3 can be fixedly installed with the help of the mounting plate 26, the connecting groove 28, and the second stud 27 to prevent them from falling off when suspended. By opening the screw hole 5 and setting the first stud 6, the sliding buckle 7 can be fixed when it moves to a suitable height. The combined design of the slot 17 and the conductive arm 16 ensures that the current is stably conducted through the conductive arm 16 to the support frame 8 and the hook, which facilitates the electroplating process.

[0025] Please see Figure 2 and Figure 3 The support frame 8 has multiple through slots 14 on both sides, and multiple second hooks 15 are slidably connected in the multiple through slots 14. The bottom of the frame 1 is fixedly connected to a base plate 19, and the top of the base plate 19 is fixedly connected to one side of the frame 1 with the same reinforcing plate 18. The bottom of the support frame 8 has an opening. The surfaces of the support frame 8, the sliding buckle 7, and the frame 1 are coated with a corrosion-resistant coating. The contact surface between the conductive arm 16 and the slot 17 is plated with a copper conductive layer. The surfaces of the first hook 13 and the second hook 15 are plated with a nickel-phosphorus alloy coating. The groove 14 provides a sliding track for the second hook 15. With the movement of the threaded plate 20 along the screw 21, the second hook 15 can move within the groove 14. The threaded plate 20 and the second hook 15 can be limited. By setting the reinforcing plate 18 and the base plate 19, the triangular support structure can prevent the frame 1 from tilting due to gravity. The corrosion-resistant coating can resist the chemical corrosion of the electroplating solution. The copper conductive layer has high conductivity and anti-oxidation properties. By setting the opening, when the frame 1 is removed from the electrolyte pool, the electrolyte can be discharged from the opening.

[0026] The working principle of the above embodiment is as follows: When using the electroplating hanger, the hanger is first suspended by the connecting buckle 3 at the top of the frame 1. Then, the movable frame 25 is closed and the two mounting plates 26 are fixed by the second stud 27 and the nut to prevent them from falling off during suspension. Next, the sliding buckle 7 is slid along both sides of the frame 1 to adjust the position of the support frame 8. After adjusting to a suitable height, the sliding buckle 7 is fixed by the first stud 6 and the screw holes 5 on both sides of the frame 1 to complete the position fixation of the support frame 8. Then, the knob 9 is turned, which drives the second rotating shaft 10 and the worm gear 24 to rotate. The worm gear 24 meshes with the worm wheel 23 to drive the first rotating shaft 22 and the lead screw 21 to rotate, so that the threaded plate 20 moves along the axial direction of the lead screw 21, driving the sliding connection on both sides of the support frame 8. The second hook 15 in the side channel 14 moves to adjust the distance between the second hook 15 and the first hooks 13 on both sides of the connecting frame to adapt to the clamping requirements of workpieces of different sizes. The workpiece is placed outside the first hook 13 and the second hook 15 to expand and fix the workpiece. The conductive arm 16 is slidably connected in the slot 17 at the top of the support frame 8 and contacts the support frame 8. The fit design of the slot 17 and the conductive arm 16 can ensure that the current is stably conducted through the conductive arm 16 to the support frame 8 and the hook. Then the hanger is immersed in the electroplating solution for electroplating. The corrosion-resistant coating on the surface of the support frame 8, the sliding buckle 7 and the frame 1 can resist the chemical corrosion of the electroplating solution. The nickel-phosphorus alloy plating on the surface of the first hook 13 and the second hook 15 can reduce hook wear.
