Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, specifically to a swing-type electroplating rack. Background Technology

[0002] Electroplating, a core technology in surface treatment, deposits metal or alloy coatings on substrate surfaces through electrolysis. It is widely used in industries such as automotive, electronics, and aerospace, offering multiple benefits including protection, decoration, and functional enhancement. Electroplating is based on Faraday's law of electrolysis. Under a direct current electric field, the anolyte metal dissolves to generate ions, which are then reduced on the cathode surface of the workpiece to form a coating. Based on function, coatings can be categorized as protective coatings (such as zinc and cadmium coatings for corrosion prevention), decorative coatings (such as copper-nickel-chromium three-layer coatings to enhance appearance), and functional coatings (such as hard chrome coatings to enhance wear resistance). Electroplating racks are indispensable tools in the electroplating process. Their core function is to ensure the workpiece maintains a stable position in the electroplating solution through mechanical fixation and current conduction, achieving uniform coating deposition. During electroplating, the workpiece is hung on hooks on the rack. To ensure uniform coating, the electroplating rack typically needs to reciprocate left and right movements within the electroplating bath.

[0003] However, when using existing electroplating racks to hang workpieces for electroplating, plating defects are prone to occur at the connection between the workpiece and the hook, affecting the electroplating quality of the workpiece. Utility Model Content

[0004] The purpose of this invention is to solve the problem that plating is easily missed at the connection between the workpiece and the hook during the electroplating process of existing electroplating racks.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A swing-type electroplating rack includes an outer frame. A pair of hooks are fixedly connected to the top two sides of the outer frame. Several rotating plates are horizontally rotatably connected to the inner side of the outer frame. Several sets of hooks are detachably attached to the top two sides of the rotating plates via copper buckles. A pair of horizontal bars are symmetrically fixedly connected to the top of the hooks. A swing frame is fixedly connected between the ends of adjacent horizontal bars. Several rotating rods are hinged parallel to each other between the swing frames. A swing mechanism is provided between the top of the swing frame and the top of the outer frame. The swing mechanism includes an automatic reset damping shaft. The automatic reset damping shaft is rotatably connected to the middle of the top side wall of the outer frame. A lever is vertically fixedly connected to one end of the automatic reset damping shaft. A cam is fixedly connected to the other end of the automatic reset damping shaft. A connecting shaft is rotatably connected to the protruding part of the side wall away from the automatic reset damping shaft. A slider is slidably connected to the connecting shaft. The bottom of the slider is slidably connected to the swing frame.

[0007] Furthermore, a sliding plate is horizontally fixed to the top of the swing frame facing the slider, and a sliding groove is horizontally opened on the side wall of the sliding plate, through which the slider is slidably connected to the sliding plate.

[0008] Furthermore, a blocking frame is horizontally provided between the bottoms of each of the rotating plates, and the two ends of the blocking frame are fixedly connected to the side wall of the outer frame.

[0009] Furthermore, a placement rack is horizontally fixedly connected to the bottom of the outer frame, and several protective plates are symmetrically fixedly connected to both sides of the outer frame.

[0010] Furthermore, an elastic plate is fixedly connected to the side wall of the hook, the top of the elastic plate is inclined in the direction of the hook opening, and a fixing rod is horizontally fixedly connected between a pair of hooks.

[0011] Furthermore, the hook, outer frame, rotating plate, and hook are all made of conductive material, while the swing mechanism, swing frame, blocking frame, and rotating rod are all made of insulating material.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4The oscillating electroplating rack of this embodiment includes an outer frame 1. A pair of hooks 2 are fixedly connected to the top two sides of the outer frame 1. Several rotating plates 5 are horizontally rotatably connected to the inner side of the outer frame 1. Several sets of hooks 6 are detachably connected to the top two sides of the rotating plates 5 via copper buckles 7. A pair of horizontal bars 8 are symmetrically fixedly connected to the top of the hooks 6. A swing frame 9 is fixedly connected between the ends of adjacent horizontal bars 8. Several rotating rods 10 are hinged in parallel between the swing frames 9. A swing mechanism 11 is provided between the top of the swing frame 9 and the top of the outer frame 1 to drive the hooks 6 and the workpiece to swing during electroplating. The swing mechanism 11 includes an automatic reset damping rotating shaft 1102. The automatic reset damping rotating shaft 1102 and the automatic reset damping rotating shaft 1102 are connected to the outer frame 1002 and the outer frame 1002 to ... The top side wall of the outer frame 1 is rotatably connected to the end of the automatic reset damping shaft 1102, which is vertically fixed to a lever 1101. The other end of the automatic reset damping shaft 1102 is fixedly connected to a cam 1103. The side wall protrusion of the cam 1103 away from the automatic reset damping shaft 1102 is rotatably connected to a connecting shaft 1104. A slider 1105 is slidably connected to the connecting shaft 1104. The bottom of the slider 1105 is slidably connected to the swing frame 9. A slide plate 1106 is horizontally fixedly connected to the top of the swing frame 9 facing the slider 1105. A groove 1107 is horizontally opened on the side wall of the slide plate 1106. The slider 1105 is slidably connected to the slide plate 1106 through the groove 1107.During electroplating, the workpiece is evenly hung on the hooks 6 on both sides of the outer frame 1. Then, the electroplating rack is hung on the bottom of the target using the hooks 2. The electroplating rack and workpiece are then immersed in the electroplating tank by the conveying mechanism, where a stop is provided at the top of the electroplating tank. During the electroplating process, the conveying mechanism drives the outer frame 1 to perform periodic reciprocating motion in the electroplating tank, making the electroplating of the workpiece surface more uniform. When the outer frame 1 moves, it drives the lever 1101 to move accordingly. During the movement of the lever 1101, it begins to swing due to the obstruction of the stop at the top of the electroplating tank, which drives the automatic reset damping shaft 1102 to start rotating. When the automatic reset damping shaft 1102 rotates, it drives the cam 1103 to start rotating, which causes the connecting shaft 1104 on the other side of the cam 1103 to start rotating. When the connecting shaft 1104 rotates, it drives the slider 1105 on its outer side to start rotating. When the slider 1105 rotates, it slides horizontally along the sliding surface. The tank 1107 begins to slide, simultaneously driving the slide rod 1106 to begin lifting and lowering in the vertical direction. As the slide rod 1106 moves, it drives the connected swing frame 9 to move vertically, causing the rotating rod 10, hinged to the swing frame 9, to rotate around the axis connecting the rotating plate 5 and the outer frame 1. This causes the rotating plate 5 and hook 6 to swing accordingly. When the hook 6 swings, the workpiece at its bottom remains vertically downward under gravity, causing the contact point between the workpiece and the hook 6 to shift. When the lever 1101 moves past the stop at the top of the electroplating tank, it resets at a constant speed under the action of the automatic reset damping shaft 1102, causing the hook 6 and workpiece to reset as well. This allows the hook 6 and workpiece to reciprocate during the periodic reciprocating motion of the electroplating rack, increasing the contact area between the workpiece and the electroplating solution, achieving uniform electroplating of the workpiece from all directions, and preventing missed plating.

[0021] Each rotating plate 5 has a horizontally arranged blocking frame 12 at its bottom, with both ends of the blocking frame 12 fixedly connected to the side wall of the outer frame 1. A placement frame 14 is horizontally fixedly connected to the bottom of the outer frame 1, and several protective plates 13 are symmetrically fixedly connected to both sides of the outer frame 1. During the swaying process of the workpiece, the blocking frame 12 can prevent the workpieces on both sides from contacting each other, thus improving the electroplating quality. The placement frame 14 can be used to counterweight the bottom of the outer frame 1, improving the stability of the outer frame 1 during movement. The protective plates 13 can protect the workpiece.

[0022] An elastic plate 3 is fixedly connected to the side wall of the hook 2. The top of the elastic plate 3 is inclined in the direction of the opening of the hook 2. A fixing rod 4 is horizontally fixedly connected between a pair of hooks 2. By setting the elastic plate 3, the hook 2 can be supported when the electroplating rack is hoisted, so that the hook 2 is always in close contact with the target and avoids the current fluctuation during electroplating.

[0023] The hook 2, outer frame 1, rotating plate 5 and hook 6 are all made of conductive material, while the swing mechanism 11, swing frame 9, blocking frame 12 and rotating rod 10 are all made of insulating material.

[0024] Working principle: During electroplating, the workpiece is evenly hung on the hooks 6 on both sides of the outer frame 1. Then, the electroplating rack is hung on the bottom of the target using the hooks 2. The electroplating rack and workpiece are then immersed in the electroplating tank by the conveying mechanism, where a stop is provided at the top of the electroplating tank. During the electroplating process, the conveying mechanism drives the outer frame 1 to perform periodic reciprocating motion in the electroplating tank, making the workpiece surface more evenly electroplated. When the outer frame 1 moves, it drives the lever 1101 to move accordingly. During the movement of the lever 1101, it begins to swing due to the obstruction of the stop at the top of the electroplating tank, driving the self-... When the automatic reset damping shaft 1102 starts to rotate, it drives the cam 1103 to rotate, causing the connecting shaft 1104 on the other side of the cam 1103 to rotate. When the connecting shaft 1104 rotates, it drives the slider 1105 on its outer side to rotate. When the slider 1105 rotates, it slides horizontally along the slide groove 1107, and at the same time, it drives the slide rod 1106 to start moving up and down in the vertical direction. When the slide rod 1106 moves, it drives the swing frame 9 connected to it to move in the vertical direction, so that the rotating rod 1105, which is hinged to the swing frame 9, moves vertically. The rotating plate 5 begins to rotate around the pivot at the connection point between the rotating plate 5 and the outer frame 1, causing the rotating plate 5 and hook 6 to swing accordingly. When hook 6 swings, the workpiece at its bottom remains vertically downward under the action of gravity, thus causing the contact point between the workpiece and hook 6 to shift. When the lever 1101 moves past the stop at the top of the electroplating tank, it returns to its original position at a constant speed under the action of the automatic reset damping shaft 1102, causing hook 6 and workpiece to return to their original positions. This allows hook 6 and workpiece to reciprocate during the periodic reciprocating motion of the electroplating rack, improving the contact between the workpiece and the electroplating solution. The contact area ensures uniform electroplating of the workpiece from all directions, preventing missed plating. During the workpiece's swaying process, the blocking frame 12 prevents contact between the workpieces on both sides, improving electroplating quality. The placement frame 14 provides counterweight to the bottom of the outer frame 1, improving its stability during movement. The protective plate 13 protects the workpiece. The elastic plate 3 supports the hook 2 during hoisting of the electroplating rack, ensuring the hook 2 remains in close contact with the target, preventing current fluctuations during electroplating.
