Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of electroplating tank technology, and more specifically, to screw electroplating tanks. Background Technology

[0002] Screws are a common type of fastener, typically consisting of a head and a shank. They can be used to fasten two or more components together via threaded connections. After screw production, to improve performance and extend service life, screws are usually placed in an electroplating tank for electroplating. During electroplating, several screws are placed on a rack, which then moves the rack along with the screws into the electroplating solution in the tank. After the power is connected, the screws are electroplated. Once electroplating is complete, the screws are removed from the rack.

[0003] After removing the rack, electrolyte may adhere to or be attached to the rack and screws. Therefore, in order to avoid wasting electrolyte, a "drainage" process is usually performed after removal, allowing the attached electrolyte to fall into the electroplating tank or collection box for later use and to prevent waste.

[0004] However, during liquid control, workers usually just hold the rack or use an automated device to move it above the electrolytic tank. Gravity usually causes the electrolyte to fall into the electroplating tank, but after most of the electrolyte falls, some electrolyte will still adhere to the rack or screws. The adhesion is strong, and gravity alone cannot make it fall completely. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a screw electroplating tank to solve the technical problem in the prior art that after the screws are electroplated and removed, it is difficult to remove most of the electrolyte adhering to the hanger and screws by gravity alone.

[0006] According to one aspect, at least one embodiment of this disclosure provides a screw electroplating tank, including a tank body and a hanger, and further including a centrifuge cylinder, a translation component, a lifting component, and a liquid-spraying component. The centrifuge cylinder is detachably mounted on the side of the tank body via two connecting rods. The translation component is disposed at the top of the connecting rods for moving the electroplated hanger into the centrifuge cylinder. The lifting component is disposed on the translation component for lifting and lowering the hanger. The liquid-spraying component is disposed on the lifting component, and the hanger is disposed on the liquid-spraying component via a mounting component for driving the hanger to rotate within the centrifuge cylinder.

[0007] Furthermore, the translation component includes a support cover, a reciprocating screw, a first motor, and a sliding component. The support cover is fixedly mounted on the connecting rod. The reciprocating screw is rotatably mounted inside one of the support covers, and a matching crescent-shaped slider is mounted on the reciprocating screw. The first motor is mounted on the side of the support cover, and the output end of the first motor is coaxially connected to the reciprocating screw. The sliding component is disposed inside the other support cover.

[0008] Furthermore, the sliding assembly includes a sliding rod, a sliding block, and a top frame. The sliding rod is fixedly installed inside another support cover, the sliding block is slidably installed on the sliding rod, and the top frame is fixedly installed on the top of both the sliding block and the crescent-shaped slider.

[0009] Furthermore, the lifting assembly includes electric push rods and connecting frames. The electric push rods are installed on the top frame, and the connecting frames are fixedly installed on the output ends of the two electric push rods.

[0010] Furthermore, the liquid-spinning assembly includes a second motor and a rotating shaft. The second motor is mounted on the connecting frame, and the rotating shaft is coaxially connected to the output end of the second motor.

[0011] Furthermore, the mounting assembly includes mounting blocks, mounting plates, and mounting bolts. Two mounting blocks are fixedly mounted on the side of the rotating shaft, and threaded holes are provided on the side of the mounting blocks. Two mounting plates are fixedly mounted on the top of the hanger, and threaded holes are provided on the mounting plates. The mounting bolts are threaded into the threaded holes.

[0012] In order to install the screws that need to be electroplated on the hanger, further, several hanging plates are fixedly installed on the hanger, and the hanging plates are provided with threaded holes.

[0013] In order to seal the centrifuge tube when the hanger rotates inside the centrifuge tube, the top of the centrifuge tube is further fitted with two semi-cylindrical caps by snap-fit, and the semi-cylindrical caps are provided with semi-circular through grooves.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, after the screw is electroplated, the hanger and the screw on the hanger can be raised by the lifting assembly and positioned above the electroplating tank. Under the action of gravity, most of the electrolyte on the hanger and the screw falls into the electroplating tank, thereby avoiding waste of electrolyte. 2. In this disclosure, after most of the electrolyte is dripped into the electroplating tank, the hanger and screw are moved into the centrifuge tube by the translation component, and placed into the centrifuge tube by the lifting component. Then, the electrolyte on the hanger and screw is spun into the centrifuge tube by the liquid-spinning component, thereby further collecting the electrolyte adhering to the hanger and screw. In summary, this electroplating tank, through the cooperation of the centrifuge cylinder, translation component, lifting component, and liquid-spraying component, can move and rotate the hangers and screws after electroplating, thereby collecting the electrolyte adhering to their surfaces more thoroughly.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-5As shown, a screw electroplating tank according to an embodiment of the present disclosure is illustrated, including a tank body 1 and a hanger 2, as well as a centrifuge cylinder 3, a translation component, a lifting component, and a liquid-spraying component. The centrifuge cylinder 3 is detachably mounted on the side of the tank body 1 via two connecting rods 4. The translation component is located at the top of the connecting rods 4 and is used to move the electroplated hanger 2 into the centrifuge cylinder 3. The lifting component is located on the translation component and is used to lift and lower the hanger 2. The liquid-spraying component is located on the lifting component, and the hanger 2 is mounted on the liquid-spraying component via a mounting component to drive the hanger 2 to rotate inside the centrifuge cylinder 3.

[0025] like Figure 2 and Figure 3 As shown, during electroplating, several mounting plates 20 are fixedly installed on the hanger 2, and the mounting plates 20 have threaded holes. The screws to be electroplated can be threaded onto the mounting plates 20 of the hanger 2. It should be noted that the threaded holes of the mounting plates 20 are compatible with the screws to be electroplated. After installation, the hanger 2 is installed on the rotating shaft 15 using an installation assembly. The installation assembly includes mounting blocks 16, mounting plates 17, and mounting bolts 18. Two mounting blocks 16 are fixedly installed on the side of the rotating shaft 15, and the side of the mounting blocks 16 has threaded holes. Two mounting plates 17 are fixedly installed on the top of the hanger 2, and the mounting plates 17 have threaded holes. The mounting bolts 18 are threaded into the threaded holes. Specifically, the two mounting plates 17 are respectively aligned with the threaded holes of the two mounting blocks 16, and the mounting bolts 18 are threaded into the mounting plates 17 and mounting blocks 16 to fix them.

[0026] like Figure 2 As shown, after fixing, the hanger 2 is placed into the electroplating tank by the lifting assembly. The lifting assembly includes an electric push rod 12 and a connecting frame 13. The top frame 11 is equipped with an electric push rod 12. The connecting frame 13 is fixedly installed on the output end of the two electric push rods 12. When the electric push rod 12 is started, the output end of the electric push rod 12 drives the connecting frame 13 to move down, thereby placing the hanger 2 along with the screw into the electrolyte in the tank 1 for subsequent electroplating.

[0027] like Figure 4As shown, after electroplating, the hanger 2 can be lifted up and left to stand for a period of time, allowing some of the electrolyte to fall into the tank 1 by gravity. Then, the hanger 2 and screw are moved into the centrifuge 3 by the translation component. The translation component includes a support cover 5, a reciprocating screw 6, a first motor 8, and a sliding component. The support cover 5 is fixedly installed on the connecting rod 4. The reciprocating screw 6 is rotatably installed in one of the support covers 5, and a matching crescent slider 7 is installed on the reciprocating screw 6. The first motor 8 is installed on the side of the support cover 5, and the output end of the first motor 8 is coaxially connected to the reciprocating screw 6. The sliding component is set in another support cover 5. The sliding component includes a sliding rod 9, a sliding block 10, and a top frame 11. The sliding rod 9 is fixedly installed in the other support cover 5, and the sliding block 10 is slidably installed on the sliding rod 9. The top of the sliding block 10 and the crescent slider 7 are both fixedly installed with the top frame 11.

[0028] like Figure 2 As shown, specifically, the first motor 8 is started, and the output end of the first motor 8 drives the reciprocating screw 6 to rotate inside the support cover 5. It should be noted that the crescent-shaped slider 7 is mounted on the reciprocating screw 6 via a reciprocating sleeve, which is a known technology. The crescent-shaped slider 7 then moves left and right on the reciprocating screw 6, driving the sliding block 10 at the other end to move synchronously on the sliding rod 9 under the connection of the top frame 11 and the connecting frame 13. This moves the hanger 2 and screw above the centrifuge cylinder 3. Then, the electric push rod 12 is started to place the hanger 2 and screw into the centrifuge cylinder 3. Finally, the electrolyte adhering to the hanger 2 is rotated inside the centrifuge cylinder 3 by the liquid-spinning assembly, causing the electrolyte to be thrown off the hanger 2. The liquid assembly includes a second motor 14 and a rotating shaft 15. The second motor 14 is mounted on the connecting frame 13, and the rotating shaft 15 is coaxially connected to the output end of the second motor 14. Specifically, by starting the second motor 14, the output end of the second motor 14 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the hanger 2 to rotate, thereby shaking off the electrolyte adhering to it. The top of the centrifuge cylinder 3 is fitted with two semi-cylindrical covers 19 by snap-fit, and the semi-cylindrical covers 19 are provided with semi-circular through grooves. The two semi-circular through grooves fit against the outer wall of the rotating shaft 15, thereby covering the top of the centrifuge cylinder 3 with the semi-cylindrical covers 19 to prevent the electrolyte from being thrown out of the centrifuge cylinder 3 during the liquid shaking process.

[0029] Working principle: When electroplating screws, the screws to be electroplated are first installed on the hanging plate 20 of the hanger 2. Then, the electric push rod 12 is started, and the output end of the electric push rod 12 drives the connecting frame 13 to move down, thereby placing the hanger 2 along with the screws into the electrolyte in the electroplating tank for electroplating. After electroplating is completed, the electric push rod 12 is started again to lift the hanger 2 up. After standing for a period of time, some of the electrolyte falls into the tank 1 by gravity. Then, the first motor 8 is started, and the output end of the first motor 8 drives the reciprocating screw 6 to rotate inside the support cover 5. The crescent-shaped slider 7 moves left and right on the reciprocating screw 6. Under the connection of the top frame 11 and the connecting frame 13, it drives the sliding block 10 at the other end to move synchronously on the sliding rod 9, thereby moving the hanger 2 and the screw above the centrifuge cylinder 3. Then, the electric push rod 12 is activated to place the hanger 2 and the screw into the centrifuge cylinder 3. Finally, the second motor 14 is activated, and the output end of the second motor 14 drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the hanger 2 to rotate, thereby throwing off the electrolyte adhering to it. Finally, the centrifuge cylinder 3 is disassembled for electrolyte collection.

[0030] like Figure 5 As shown, during electroplating, wires are connected to the side of the tank 1 to connect the screw to the negative terminal of the power supply. Then, the anode (such as a zinc plate for galvanizing or a copper plate for copper plating) inside the tank 1 is connected to the positive terminal of the power supply. The electrolyte provides an ion source for deposition and maintains a stable electrochemical environment, thereby electroplating the screw. During electroplating, the top of the tank 1 can be covered by a cover plate. All electronic devices in this device are powered by the power supply connected to the tank 1, and a protective sleeve is installed on the outside of the reciprocating screw 6.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
