The cathode flybar for rack plating drives the movable bracket to move upward relative to the conductive rod during hoisting, so that the sub-hanger and the mother hanger on the electroplating hanger move relative to each other, thereby causing the workpiece to perform a certain degree of flipping movement in the process of leaving the electroplating solution, so that the residual electroplating solution on the workpiece can flow out smoothly, thereby achieving the design purpose in a simple manner and having a low manufacturing cost.

Description

Technical Field

[0001] The invention relates to the technical field of electroplating, and in particular to a cathode flybar for rack plating. Background Art

[0002] Rack plating is an electroplating process. Its basic principle is to hang the workpiece to be plated on a plating hanger with good conductivity, and then immerse it in the plating solution. The metal ions are reduced to metal on the surface of the workpiece through the action of electric current, forming a uniform and dense plating layer. Among them, metal anodes are placed on both sides of the plating tank, and the workpiece hung in the middle of the tank is used as the cathode. The cathode flybar is used to carry the plating hanger for hanging the workpiece.

[0003] After the workpiece is electroplated, it leaves the plating solution under the pulling action of the cathode flybar. Due to the effect of gravity, most of the plating solution on the workpiece will flow back to the plating tank, but there is still some plating solution in the blind holes that cannot flow out. At this time, the posture of the workpiece needs to be changed so that the residual plating solution can flow out to avoid contaminating the plating solution of the next process.

[0004] To change the posture of the workpiece, it is generally achieved by driving the workpiece through the electroplating hanger. A driving part needs to be set on the electroplating hanger, which increases the complexity of the structure and urgently needs further optimization. Summary of the invention

[0035] In addition, the terms "first", "second", etc. are merely used to distinguish in description and have no special meanings.

[0036] See also Figures 1 to 4 As shown, this embodiment provides a cathode flybar for hanging plating, especially for hanging Figure 1 The electroplating rack 4 includes a mother rack 41 and a child rack 42. The mother rack 41 is used to hang the workpiece, and the child rack 42 is used to push the workpiece to flip when moving relative to the mother rack 41.

[0037] The cathode flybar comprises a main support 1, a conductive rod 2 and a movable frame 3, wherein:

[0038] The top two ends of the main support 1 are crane hoisting parts 11;

[0039] The conductive rod 2 is installed at the bottom of the main bracket 1, and cathode conductive heads 21 are arranged at both ends of the conductive rod 2. The middle part of the conductive rod 2 is used to hang the female hanger 41;

[0040] The movable frame 3 is movably arranged on the main support 1 and is located above the conductive rod 2. Hanging rods 31 are arranged at both ends of the movable frame 3. The middle part of the movable frame 3 is used to hang the sub-hanger 42.

[0041] During hoisting, the suspension rod 31 is hoisted together with the traveling hoisting part 11 , and the suspension rod 31 abuts against the traveling hoisting part 11 , so that the movable frame 3 is away from the conductive rod 2 , and the mother hanger 41 and the child hanger 42 move relatively.

[0042] Therefore, by driving the movable frame 3 to move upward relative to the conductive rod 2 during hoisting, the sub-hanger 42 and the mother hanger 41 of the electroplating hanger 4 are moved relative to each other, so that the workpiece is flipped to a certain extent in the process of leaving the electroplating liquid, so that the residual electroplating liquid on the workpiece can flow out smoothly, thereby simply achieving the design purpose and low manufacturing cost.

[0043] Optionally, the main support 1 includes a cross beam 12 and columns 13 , the crane hoisting part 11 is located at both ends of the cross beam 12 , the two columns 13 are fixed to the lower surface of the cross beam 12 , and the conductive rod 2 is fixed to the bottom ends of the two columns 13 .

[0044] Optionally, the movable frame 3 includes two side rods 32, which are distributed on both sides of the main bracket 1. The two side rods 32 are fixedly connected by a connecting plate 33. Through holes 14 are respectively opened on the two columns 13. The suspension rod 31 passes through the through holes 14 and is fixedly connected to the connecting plate 33. The through holes 14 are used to limit the suspension rod 31 to limit the moving range of the movable frame 3.

[0045] Thus, the movable frame 3 is switched between the first state and the second state. When the cathode flybar is placed in the slot of the electroplating tank, the movable frame 3 is in the first state due to the gravity. Figure 2 When the cathode flying bar is hoisted, the suspension rod 31 of the movable frame 3 is lifted together, and the movable frame 3 is in the second state, see Figure 3 .

[0046] Furthermore, sliding blocks 15 are respectively provided on both side surfaces of the two upright posts 13 for sliding contact with the side rods 32 on the corresponding sides.

[0047] Thus, the two side rods 32 are slidably matched with the two upright posts 13 to ensure that the movable frame 3 can be lifted and lowered smoothly.

[0048] Optionally, stoppers 16 are respectively provided on both side surfaces of the two upright posts 13 , and stoppers 34 extending to below the stoppers 16 are provided on the side bars 32 .

[0049] Therefore, by cooperating between the stopper 16 and the side rod 32, the lower travel limit of the movable frame 3 is limited, thereby improving the support of the movable frame 3 for the electroplating rack 4 and the workpiece; by cooperating between the stopper 16 and the stop rod 34, the upper travel limit of the movable frame 3 is limited, thereby providing an additional layer of safety protection.

[0050] Optionally, the main support 1 further includes a plurality of auxiliary columns 17 located between the two upright columns 13 , the top ends of the auxiliary columns 17 are fixed to the lower surface of the cross beam 12 , and the bottom ends of the auxiliary columns 17 are fixed to the conductive rod 2 .

[0051] Furthermore, a baffle 35 is provided on the movable frame 3 and moves along one side or both sides of the auxiliary column 17 .

[0052] Therefore, the supporting performance of the conductive rod 2 is improved by the auxiliary column 17 , and the accurate lifting and lowering of the movable frame 3 is further ensured by the baffle plate 35 .

[0053] Optionally, a reinforcing plate 18 is respectively provided on the two upright posts 13 , and the reinforcing plate 18 extends along the upper surface of the conductive rod 2 to the top of the cathode conductive head 21 at the corresponding end.

[0054] Therefore, the structural strength of the cathode conductive head 21 on the conductive rod 2 is improved by the reinforcing plate 18 .

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
