Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and more specifically, to a surface cleaning structure for electroplating of copper fixtures. Background Art

[0002] In the electroplating industry, copper fixtures are widely used as hanging carriers for electroplating various workpieces due to their good electrical conductivity, strength, corrosion resistance and other characteristics. During long-term use, after each electroplating, a large amount of plating solution will remain on the surface of the copper fixtures. If the metal ions, additives and other components contained in the plating solution are not cleaned in time, they will crystallize and precipitate on the surface of the fixtures, which not only causes waste of the plating solution and increases production costs, but also changes the surface state and dimensional accuracy of the fixtures, affecting the subsequent adaptability with the workpieces. Therefore, it is necessary to clean the surface of the copper fixtures.

[0003] For example, the patent with the publication number CN211726628U discloses a device for cleaning the plating solution on the surface of an electroplating fixture. After electroplating is completed, the fixture is placed horizontally on the fixture placement rack, and the placement rack is pushed to move on the fixture cleaning rack. The waveform rod at the lower end of the fixture placement rack slides along the upper surface of the lower flap plate, driving the lower flap plate to swing around the fulcrum cross bar. The swing causes the two brush plates at the upper end of the lower flap plate to move up and down reciprocally, and the brush plates fit against the moving fixture to brush both sides of the fixture. However, the existing cleaning device only brushes the surface of the fixture with a simple brush, but for the solidified plating solution components on the fixture, the brushing efficiency of the brush is slow, and the cleaning and removal effect for stubborn residues is not ideal.

[0004] Therefore, a surface cleaning structure for electroplating of copper fixtures is introduced. Summary of the Invention

[0005] The purpose of the present invention is to provide a surface cleaning structure for electroplating of copper fixtures, aiming to solve the problem in the above background art that when the existing cleaning device brushes the fixture with a brush, the cleaning and removal effect of the brush on the solidified residual plating solution on the fixture is not ideal.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1 and Figure 2, A surface cleaning structure for electroplating a copper fixture, including a cleaning tank 1. Support legs are fixedly connected to the four corners of the bottom of the cleaning tank 1. A flip cover 2 is movably arranged on one outer wall of the top port of the cleaning tank 1 through a hinge. Positioning grooves 11 are respectively opened on both sides of the top port of the cleaning tank 1. A T-shaped cross frame 12 is movably connected in the positioning groove 11 on one side of the cleaning tank 1. A hanging hole is opened at the bottom of the middle section of the T-shaped cross frame 12. A fixture body 3 is suspended in the hanging hole. The fixture body 3 is pickled in the cleaning tank 1 to remove oxides or metals in the residual cured plating solution on the surface of the fixture body 3. The T-shaped cross frame 12 has a certain thickness, and the size of the hanging hole matches the size of the top hook of the fixture body 3, maintaining the stability of the suspension of the fixture body 3 to a certain extent and making it not easy to tilt. A PLC controller (model Siemens S7-1200) for controlling the operation of the equipment is installed on one outer wall of the cleaning tank 1. A drain valve pipe 13 is fixedly connected to the outer wall of the cleaning tank 1 near the bottom on the other side. An acid liquid inlet pipe 14 and a clear water inlet pipe 15 are successively arranged on the outer wall of the cleaning tank 1 above the drain valve pipe 13. The acid liquid inlet pipe 14 and the clear water inlet pipe 15 respectively introduce acid liquid and clear water into the cleaning tank 1 to pickle and soak and wash the fixture body 3 respectively.

[0030] In order to solve the problem that when the existing cleaning device relies on a brush to brush the fixture, the cleaning and removal effect of the cured residual plating solution on the fixture by the brush is not ideal, please refer to Figures 1-5 , the following preferred technical solutions are provided:

[0031] A rotating shaft 4 is movably connected to the bottom plate of the cleaning tank 1. The lower end of the rotating shaft 4 penetrates and extends outside the bottom plate of the cleaning tank 1. A motor is fixedly connected to the lower end of the bottom plate of the cleaning tank 1. The output end of the motor is fixedly connected to the lower end of the rotating shaft 4. An L-shaped frame 5 is fixedly connected to the top of the rotating shaft 4. A chute 51 is opened at the upper end of the bottom plate on one side of the vertical rod of the L-shaped frame 5. A first cleaning brush 52 and a second cleaning brush 53 are respectively movably clamped on both sides in the chute 51. Auxiliary parts 54 are respectively fixedly connected to the outer walls on both sides of the first cleaning brush 52;

[0032] The auxiliary part 54 includes fixing bars 541 fixedly connected to the outer walls on both sides of the first cleaning brush 52. The ends of the fixing bars 541 are fixedly connected with L-shaped plates 542. At the top end of the horizontal plate of the L-shaped plate 542, a roller 543 is movably connected. At the top of the vertical plate of the L-shaped plate 542, a U-shaped groove 544 is provided. Between the inner walls of the U-shaped groove 544, a vibrating rod 545 is movably connected. One end of the vibrating rod 545 is obliquely suspended above the top of the fixture body 3. On the outer walls on both sides of the lower inclined end of the vibrating rod 545, limiting grooves 546 are opened. In the limiting grooves 546, U-shaped rods 547 are movably engaged. In the middle of the lower end of the U-shaped rod 547, a moving rod 548 is fixedly connected. The other end of the moving rod 548 movably penetrates and extends to the other side of the vertical plate of the L-shaped plate 542, and the end of the moving rod 548 is movably connected with a movable connecting rod 549. The end of the movable connecting rod 549 is movably connected to the edge at one end of the top of the roller 543.

[0033] Between the inner walls at both ends of the chute 51, a bidirectional lead screw 511 is movably arranged. On the outer walls at both ends of the bidirectional lead screw 511, moving blocks 512 are respectively threadedly connected. On the tops of the moving blocks 512 on both sides of the chute 51, the first cleaning brush 52 and the second cleaning brush 53 are respectively fixedly connected. And the vertical rod of the L-shaped frame 5 is of a hollow structure. One end of the bidirectional lead screw 511 penetrates and extends into the inner cavity of the L-shaped frame 5 and then the end is fixedly connected with a bevel gear set 513. At the top of the bevel gear set 513, an adjusting rod 514 is fixedly connected. The top end of the adjusting rod 514 penetrates and extends to the outside of the top end of the vertical rod of the L-shaped frame 5.

[0034] The composition structure of the first cleaning brush 52 is the same as that of the second cleaning brush 53. When the fixture body 3 is suspended inside the cleaning tank 1, the side bristles of the first cleaning brush 52 and the second cleaning brush 53 are respectively arranged in contact with the inner and outer walls of the fixture body 3. By rotating the adjusting rod 514 at the top port of the cleaning tank 1, the adjusting rod 514 drives the bidirectional lead screw 511 to rotate in the chute 51 by means of the meshing of the bevel gear set 513. When the bidirectional lead screw 511 rotates, it drives the moving blocks 512 on both sides in the chute 51 to move left and right, so as to adjust the distance between the first cleaning brush 52 and the second cleaning brush 53, so as to simultaneously clean the inner and outer walls of the fixture body 3 of different sizes.

[0035] The U-shaped rod 547 and the moving rod 548 are arranged perpendicular to each other. When the top end of the U-shaped rod 547 is located at the inclined lower end end of the limiting groove 546, the spherical head at the upper inclined end of the vibrating rod 545 rests and fits on the top of the fixture body 3. At this time, the moving rod 548 and the movable connecting rod 549 are coaxial and parallel, and the moving rod 548 and the roller 543 maintain the maximum distance. The fixture body 3 is of a cylindrical frame structure. When the side of the roller 543 is in contact with the outer wall of the fixture body 3, the length of the roller 543 is greater than the distance length between adjacent rings on the fixture body 3.

[0036] Specifically, after hanging the fixture body 3 inside the cleaning tank 1 and immersing it in the acid solution, control the first cleaning brush 52 and the second cleaning brush 53 movably arranged on both sides of the L-shaped frame 5 to respectively clamp and fit the inner and outer walls of the fixture body 3. The motor drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the L-shaped frame 5 to drive the first cleaning brush 52 and the second cleaning brush 53 to rotate around the fixture body 3. The first cleaning brush 52 and the second cleaning brush 53 simultaneously brush the inner and outer walls of the first cleaning brush 52 and the second cleaning brush 53. While brushing, the acid solution is used to react with the oxides and metals remaining on the fixture body 3 and solidified by the plating solution. When the first cleaning brush 52 rotates along the outer wall of the fixture body 3, the rollers 543 on the top of the horizontal plates of the L-shaped plates 542 on both sides of the housing of the first cleaning brush 52 roll along the outer wall of the fixture body 3. When the rollers 543 roll, the movable connecting rod 549 drives the moving rod 548 to move left and right on the side wall of the vertical plate of the L-shaped plate 542. When the moving rod 548 moves, the U-shaped rod 547 slides along the limiting groove 546 on the side wall of the vibrating rod 545, thereby pushing the vibrating rod 545 to reciprocally deflect based on the pin shaft in the U-shaped groove 544 at the top of the vertical plate of the L-shaped plate 542. After the vibrating rod 545 reciprocally deflects, it repeatedly and automatically knocks the fixture body 3, causing the fixture body 3 to vibrate and accelerating the shaking off of the sundries treated by the acid solution reaction on its surface. At the same time, it prevents the sundries in the acid solution from adhering to the fixture body 3 again, effectively ensuring the rapid cleaning effect of the fixture body 3 and being convenient to use.

[0037] To further ensure the cleaning effect of the fixture body 3, as Figure 1 , Figure 2 and Figures 6-8 shown, the present embodiment provides the following preferred technical solutions:

[0038] A rotating circular plate 55 is fixedly connected to the outer wall of the rotating shaft 4 below the L-shaped frame 5. An arc-shaped collecting groove 56 is fixedly connected to one edge of the top end of the rotating circular plate 55. A collecting cylinder 6 is fixedly connected to the bottom plate of the cleaning tank 1 below the rotating circular plate 55. The rotating circular plate 55 movably covers the outer wall of the top port of the collecting cylinder 6. The through hole at the bottom of the end of the arc-shaped collecting groove 56 extends through to the bottom of the rotating circular plate 55, and one-way filtrating holes 551 are uniformly arranged on the top of the rotating circular plate 55 outside the rotating shaft 4.

[0039] An annular plate 61 is fixedly connected between the inner walls at the top port of the collecting cylinder 6. The top end of the annular plate 61 is arranged close to the bottom plate of the rotating circular plate 55, and magnetic blocks 62 are respectively and uniformly spaced and fixedly connected to the top end of the annular plate 61 and the bottom edge of the rotating circular plate 55. The magnetic blocks 62 corresponding to each other between the top end of the annular plate 61 and the rotating circular plate 55 are arranged with the same-named magnetic poles facing each other, using magnetic levitation to reduce the frictional resistance between the annular plate 61 and the rotating circular plate 55, thereby ensuring the smooth rotation of the rotating circular plate 55 along with the rotating shaft 4.

[0040] The lower end of the rotating shaft 4 passes through the bottom plate of the collecting cylinder 6 and extends to the outside of the bottom plate of the cleaning box 1. The lower end of the bottom plate of the cleaning box 1 is fixedly connected to a motor, and the output end of the motor is fixedly connected to the lower end of the rotating shaft 4. The inner cavity of the collecting cylinder 6 is a funnel-shaped structure. A drain valve pipe 63 is fixedly connected to the bottom of the collecting cylinder 6, and the lower end of the drain valve pipe 63 passes through and extends to the outside of the bottom plate of the cleaning box 1.

[0041] A sealing plate 561 is movably connected to the outer wall on one side of the inlet end of the arc-shaped collecting groove 56, and a driving connecting rod 562 is movably connected to the outer wall on the side of the sealing plate 561 close to the port of the arc-shaped collecting groove 56. A driving rod 563 is movably connected to the end of the driving connecting rod 562. The other end of the driving rod 563 extends through the outside of the side wall of the arc-shaped collecting groove 56, and a counterweight ball 564 is fixedly connected to the end of the driving rod 563. A telescopic isolation sleeve 565 is fixedly connected to the inner wall at the port of the arc-shaped collecting groove 56 outside the driving rod 563. The last section of the telescopic isolation sleeve 565 is fixedly sleeved on the outer wall of the driving rod 563, and a reset spring 566 is fixedly connected between the inner wall of the last section of the telescopic isolation sleeve 565 and the inner wall of the arc-shaped collecting groove 56.

[0042] The return spring 566 surrounds the outside of the driving rod 563 in the telescopic isolation sleeve 565. The driving rod 563 is arranged on the side wall of the arc-shaped collecting groove 56 at one end away from the center of the rotating circular plate 55. When the return spring 566 maintains a normal relaxation state, the sealing plate 561 seals the port of the arc-shaped collecting groove 56. At this time, the sealing plate 561, the driving connecting rod 562 and the driving rod 563 are folded and closed and parallel to each other.

[0043] Specifically, the sundries washed off from the fixture body 3 are deposited on the top of the rotating circular plate 55. When the rotating circular plate 55 rotates with the rotating shaft 4, due to the influence of the centrifugal force of rotation, the sundries deposited in the acid solution are concentrated at the outer edge of the rotating circular plate 55. The counterweight ball 564 suspended on the side wall at the port of the arc-shaped collecting groove 56 will pull the driving rod 563 outwards from the arc-shaped collecting groove 56. When the driving rod 563 is pulled outwards, it drives the telescopic isolation sleeve 565 to contract and compress the return spring 566. At the same time, the driving rod 563 drives the driving connecting rod 562 to deflect. Furthermore, the driving rod 563 uses the driving connecting rod 562 to push the sealing plate 561 away from the port of the arc-shaped collecting groove 56. After the port of the arc-shaped collecting groove 56 is opened, through the rotation of the rotating circular plate 55, the impurities deposited above the rotating circular plate 55 are scooped in and then enter the collecting cylinder 6 below the rotating circular plate 55 for deposition. When the arc-shaped collecting groove 56 rotates, due to the continuous influx of fluid, the impurities settled in the collecting cylinder 6 will not flow back into the acid solution above the rotating circular plate 55 again, thus ensuring the purity of the acid solution above the rotating circular plate 55, preventing the reaction cleaning of the solidified impurities of the residual plating solution on the fixture body 3 from being interfered by the impurities escaping from the acid solution, and preventing the impurities from reattaching to the fixture body 3. The impurities settled in the collecting cylinder 6 continuously accumulate, and the excess acid solution overflows back from the one-way filtrating hole 551 at the top of the rotating circular plate 55, filling the collecting cylinder 6 with impurity precipitation. After the cleaning is completed and the rotating circular plate 55 stops rotating, when the counterweight ball 564 loses the centrifugal influence, the return spring 566 pushes the driving rod 563 to reset. Furthermore, the driving rod 563 pulls the sealing plate 561 to re-close the port of the arc-shaped collecting groove 56. Just control the sewage valve pipe 63 at the bottom of the port of the arc-shaped collecting groove 56 to open, and the impurity dirt generated by cleaning the fixture body 3 can flow out, realizing the automatic cleaning of the equipment, avoiding the trouble of manual cleaning and subsequent separation treatment of the cleaning sundries accumulated in the cleaning tank 1, which is convenient and practical.
