Description

Technical Field

[0001] The present invention relates to a metal oxidation treatment device, in particular to a metal surface oxidation treatment device. Background Art

[0002] Metal oxide refers to a binary compound composed of oxygen and another metal chemical element. An oxide layer is formed on the surface of a metal when it is exposed to the air for a long time. As time goes by, the metal gradually rusts, which affects the stability of the metal's use. Copper has the advantages of low resistivity, high output, and low price, and is widely used in the field of conductor materials. It is made into cables, wires, contact terminals, circuit boards, and pins of various microelectronic components. However, since copper is a relatively active non-ferrous metal, it easily reacts with oxygen in the air when stored in the air to form copper oxide. Copper oxide can conduct electricity, but copper oxide has poor conductivity. It will hinder conductivity when attached to the surface of copper, causing the copper's resistance value to be too high. Due to oxidation, some copper workpieces become insensitive to contact conductivity and suffer serious power loss, reducing their use effect. As time goes by, the oxide gradually increases, and after forming a certain thickness, it begins to lose its conductive function.

[0003] At present, the anti-oxidation treatment of some copper workpieces generally adopts the methods of outer covering and spraying rust inhibitors to isolate the outside air to prevent oxidation. This method is highly targeted and is commonly used in some fixed facilities. The copper workpiece does not need to be moved when in use. For some conductive workpieces that need to be repeatedly contacted, the position will be displaced when in use and must be in the air, such as switches, terminal blocks and buttons, they all need to be exposed to the air to work, so the oxidation process is inevitable. At present, for such copper workpieces, they are basically disassembled and the surface oxidation is removed by pickling. The copper parts need to be immersed in an acidic cleaning agent specially designed to remove copper oxides to dissolve the oxides. The existing pickling method is to directly immerse the copper parts in the solution, let the acidic cleaning agent and the oxides react by standing and waiting, and finally use a brush to brush off the oxidized residues on the copper parts. However, for some oxide layers with a certain thickness, although the oxides on the surface of the copper parts can be dissolved by immersion, the residues after dissolution still adhere to the surface of the copper parts, forming a protective effect on the deeper oxides, making it impossible for the acidic cleaning agent to dissolve the deeper oxides. Finally, polishing is required to remove the oxides that have not been cleaned. Summary of the Invention

[0026] Example 1

[0027] A metal surface oxidation treatment device, such as Figures 1-8As shown, it includes a liquid storage box body 1, a sealed cover plate 2, a handle 3, an arc-shaped lock hook 4, an arc-shaped limit block 5, a power supply module 6, a conical fixing block 7, a fixed support tube 8, a first micro servo motor 8001, a fan-shaped protrusion 8002, a cross placement rack 9, a copper piece placement screen 10 and a three-state switch 11. The top rear edge of the liquid storage box body 1 is hinged to the sealed cover plate 2. The liquid storage box body 1 is made of non-metal. The handle 3 is fixed to the sealed cover plate 2 by bolts. The front side of the sealed cover plate 2 is hinged to the arc The arc-shaped locking hook 4 is located on the side opposite to the hinge point of the closed cover 2. The arc-shaped limit block 5 is welded on the liquid storage box 1. The arc-shaped limit block 5 and the arc-shaped locking hook 4 cooperate with each other to lock the closed cover 2 and the liquid storage box 1. The power supply module 6 is fixed inside the closed cover 2. The power supply module 6 is a detachable rechargeable module. The conical fixing block 7 is welded at the bottom of the liquid storage box 1. The top of the conical fixing block 7 is rotatably connected to the fixed support tube 8 through a hinge. The first fixing block 7 is installed in the fixed support tube 8. A micro servo motor 8001, the first micro servo motor 8001 is electrically connected to the power supply module 6, the output shaft of the first micro servo motor 8001 is keyed to the fan-shaped protrusion 8002, and the top of the fixed support tube 8 is fixed to the cross placement frame 9 by bolts. The connection is treated to prevent water leakage. A copper piece placement screen 10 is placed on the cross placement frame 9. The top of the cross placement frame 9 is designed to be arc-shaped. The copper piece placement screen 10 can be moved down along the arc surface and placed on the cross placement frame 9 conveniently and quickly. A three-state switch 11 is installed on the outer wall of the liquid storage box 1. The three-state switch 11 has three different states: a first state, a second state, and a third state. A single press switches to the second state, two consecutive presses switch to the second state, and three consecutive presses switch to the third state. The first state and the second state both have the function of connecting the circuit, and the second state has the function of closing the circuit. The first state of the three-state switch 11 is electrically connected to the first micro servo motor 8001. Under normal conditions, the three-state switch 11 is in the second state.

[0028] When in use, separate the arc-shaped lock hook 4 and the arc-shaped limit block 5, open the sealed cover 2, and then pour the acid cleaning agent into the liquid storage box 1. The acid cleaning agent needs to submerge the copper piece placement screen 10, and then place the oxidized copper piece on the copper piece placement screen 10. Then close the sealed cover 2, press the three-state switch 11 to the first state, and the power supply module 6 supplies power to the first micro servo motor 8001. The rotor of the first micro servo motor 8001 rotates to drive the fan-shaped protrusion 8002 to rotate. The centrifugal force of the high-speed rotation of the fan-shaped protrusion 8002 obtains a lateral excitation force, which promotes the cross-placement. The rack 9 vibrates in the direction of the exciting force, thereby realizing repeated vibration of the cross-placing rack 9, so that the oxidized copper parts placed on the copper part placement screen 10 follow the vibration, and accelerate the dissolution rate of the surface oxide layer under the immersion of the acidic cleaning agent, and disperse the oxide layer remaining dissolved on the surface, so that the deeper oxides can effectively react with the acidic cleaning agent. In this way, the oxidized copper parts can quickly separate from the dissolved oxides under the immersion of the acidic cleaning agent, so that the deeper oxides that are difficult to reach can react with the acidic cleaning agent, thereby achieving a complete cleaning effect.

A through hole is opened on the side wall near the bottom of the liquid storage box 1, and the guide metal short tube 12001 is welded in the through hole. The diameter of the guide metal short tube 12001 is adapted to the diameter of the through hole. 1 adsorbs the disc magnetic block 12002 to form a closed pipeline. The disc magnetic block 12002 has a built-in annular magnetic block, which can be adsorbed with the pipe mouth of the guide metal short tube 12001. The inner wall of the liquid storage tank body 1 is welded with a protruding fixing block 12003. The protruding fixing block 12003 is located above the guide metal short tube 12001 and near the liquid storage tank mouth 1. One end of the pull rope 12004 is connected to the protruding fixing block 12003, and the other end of the pull rope 12004 is fixedly connected to the disc magnetic block 12002.

[0031] When the acidic cleaning agent in the liquid storage tank body 1 needs to be discharged, the pull rope 12004 can be directly pulled up to pull up the disc magnetic block 12002, the pipe mouth of the guide metal short tube 12001 is opened, and the acidic cleaning agent in the liquid storage tank body 1 is discharged along the guide metal short tube 12001. After discharge, the disc magnetic block 12002 is put down and re-adsorbed and closed with the pipe mouth of the guide metal short tube 12001.

The first supporting and fixing plates 13002 are rotatably connected to the two transmission shafts 13003 together, and the two transmission shafts 13003 are away from each other. 03, multiple layers of felt wipes 13004 are wound together, the second supporting fixing plate 13005 is welded to the side of the first supporting fixing plate 13002, the second micro servo motor 13006 is fixed to the second supporting fixing plate 13005 by bolts, the power supply module 6 is connected to the second micro servo motor 13006 through a wire, the output shaft of the second micro servo motor 13006 is keyed to the input shaft of the micro gear box 13007, the output shaft of the micro gear box 13007 and one of the transmission shafts 13003 are connected by gear meshing, the second micro servo motor 13006 is electrically connected to the third state of the three-state switch 11, and the micro gear box 13007 consists of a box body with multiple gears meshing in sequence.

[0033] After the acidic cleaning agent in the liquid storage box 1 is discharged, the elastic hook plate 13001 can be pushed aside to remove the wiping structure and place it on the copper workpiece. The multi-layer felt cloth 13004 contacts the copper workpiece, and the three-state switch 11 is adjusted to the third state. The second micro servo motor 13006 starts working, and the transmission shaft 13003 rotates through the meshing transmission of the micro gear box 13007. The multi-layer felt cloth 13004 follows the rotation of the transmission shaft 13003 and contacts the copper workpiece to wipe off the residual oxides and acidic cleaning agent.

[0034] like Figure 2 As shown, it also includes a support hanging plate 16. The three adjacent sides of the copper piece where the screen 10 is placed are hinged to the support hanging plate 16, and the support hanging plate 16 is in the shape of a barb.

[0035] If the acidic cleaning agent needs to be reused, the support hanging plate 16 can be pulled up so that the support hanging plate 16 is hung on the edge of the box opening of the liquid storage box 1, so that the copper part placement screen 10 is suspended above the acidic cleaning agent liquid level. At this time, the electric wiping assembly 13 can be placed on the copper part placement screen 10 for wiping without contacting the acidic cleaning agent below.

[0036] like Figure 1 、 Figure 7As shown, it also includes an ascending limit assembly 14, and an ascending limit assembly 14 is provided on the side of the first supporting fixed plate 13002; the ascending limit assembly 14 includes a circular fixed block 14001, a fixed connecting rod 14002 and a limit hanging plate 14003, one side of the first supporting fixed plate 13002 is symmetrically connected to the circular fixed block 14001 in a rotational manner, the circular fixed block 14001 is rotatably connected to the fixed connecting rod 14002, the limit hanging plate 14003 is welded on the top of the fixed connecting rod 14002, and the limit hanging plate 14003 is matched with the box opening of the liquid storage box body 1.

[0037] When the electric wiping assembly 13 is placed on the copper piece placement screen 10 for operation, the multi-layer felt cloth 13004 may rotate, causing the electric wiping assembly 13 as a whole to jump on the copper piece placement screen 10. At this time, the fixed connecting rod 14002 can be moved with the circular fixed block 14001 as the center until it is perpendicular to the first supporting fixed plate 13002, and then the limiting hanging plate 14003 can be rotated with the fixed connecting rod 14002 as the center until it can be hung on the edge of the liquid storage box 1.

[0038] like Figure 1 As shown, a folding pull plate 15 is also included, and the inner side of the liquid storage box body 1 and the inner side of the sealed cover plate 2 are hinged together to form the folding pull plate 15.

[0039] After the sealed cover 2 is opened to the limit position, the folding pull plate 15 is unfolded to open the sealed cover 2 within a fixed range, so as to prevent the sealed cover 2 from overturning at the hinge point and damaging the hinge structure.

[0040] like Figure 1 、 Figure 8 As shown, a hollow rubber strip 17 is also included, and the contact surface of the sealing cover 2 and the liquid storage box body 1 is fixedly connected to the hollow rubber strip 17.

[0041] When the limiting hanging plate 14003 and the supporting hanging plate 16 are hung on the edge of the liquid storage box 1, the hollow rubber strip 17 itself is deformed so that the closing process of the sealed cover plate 2 is not affected.
