Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to a chemical solution recovery device for electroplating equipment. Background Art

[0002] Electroplating is a process of obtaining a metal laminate on the surface of a solid through an electrochemical method. As a protective layer for preventing corrosion on the surface of workpieces and a decorative layer for decoration, or for changing the surface characteristics of basic materials to produce a metal or alloy coating with specific components and properties. High-standard products are represented by CPUs, precision terminal connectors, and electronic integrated circuit chip boards, which require electroplating with gold to meet the industry's needs. However, the electroplating solution for gold plating is expensive due to its high gold content. In practical applications, electroplating manufacturers will recover the electroplating solution remaining on the workpieces to save the usage of electroplating solution.

[0003] In electroplating equipment for long-term continuous use of flexible coils, absorbent cotton for wrapping the flexible coil is usually arranged at the discharge end of the electroplating tank. However, the wear resistance of the absorbent cotton is poor, and the absorbent cotton needs to be frequently replaced during the actual electroplating production process, seriously affecting the electroplating production efficiency. More importantly, when the absorbent cotton is saturated with the electroplating solution, it not only cannot absorb the electroplating solution remaining on the workpiece but also smears the electroplating solution on the workpiece, resulting in a waste of the electroplating solution, with obvious defects. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a chemical solution recovery device for electroplating equipment that does not require regular replacement of any components and will not smear the electroplating solution on the workpiece after the electroplating solution is saturated.

[0005] To solve the above technical problem, the utility model adopts the following technical scheme: A chemical solution recovery device for electroplating equipment includes a recovery tank, a mounting base arranged in the recovery tank, two support rollers fixed to the mounting base, and a conductive roller arranged on the mounting base. A vertical long hole is opened in the upper part of the mounting base. A lifting seat with adjustable height is arranged at the rear of the mounting base, and a horizontal shaft fixed to the lifting seat passes through the vertical long hole and is connected to the conductive roller. It also includes an air nozzle with a spray port facing the strip workpiece and an air pipe connected to the air nozzle through an air compressor. An exhaust hole is opened in the recovery tank.

[0006] Preferably, the included angle between the spray port of the air nozzle and the traveling direction of the strip workpiece is 20 degrees to 60 degrees.

[0007] Preferably, the number of the air nozzles is two, and the two air nozzles are respectively located on the upper and lower sides of the strip workpiece.

[0008] Preferably, the conductive roller is made of copper material, and the conductive roller is electrically connected to the electroplating positive electrode or the electroplating anode of the electroplating equipment through a horizontal axis and a wire.

[0009] Preferably, the recycling box includes a front baffle, a rear baffle, a bottom plate, and two side plates connecting the front baffle and the rear baffle. The height of the front baffle is lower than that of the rear baffle. A reflux groove with a lower front and a higher rear is provided on the inner sides of the two side plates, and a sealing strip is transversely arranged on the upper edge of the front baffle.

[0010] Preferably, the recycling box further includes a cover plate connected to the upper edges of the two side plates, and the lower edge of the cover plate abuts against the sealing strip.

[0011] The beneficial effects of the present utility model are as follows: The present utility model provides a chemical solution recycling device for electroplating equipment. During the production process of the electroplating equipment, the strip workpiece enters from the right end of the recycling box, passes through the gap between the support roller and the conductive roller after being constantly pulled by two pressure rollers, and then exits from the left end of the recycling box. Due to the supporting effect of the support roller and the pressing effect of the conductive roller, the contact reliability between the conductive roller and the strip workpiece is relatively high, ensuring the stable operation of the electroplating process. Since the air nozzle sprays high-speed air flow during operation, the electroplating solution remaining on the strip workpiece is blown into the recycling box, effectively avoiding the problems of wear between the washing cotton and the strip workpiece and incomplete recycling of the electroplating solution, with high recycling efficiency, solving the problem that the existing electroplating equipment needs to be frequently opened for maintenance, and significantly improving the electroplating efficiency.

[0015] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments. The content mentioned in the embodiments does not limit the present utility model.

[0016] Such as Figures 1 to 3As shown in the figure, a chemical solution recovery device for electroplating equipment includes a recovery tank 1, a mounting base 2 disposed inside the recovery tank 1, two support rollers 3 fixed to the mounting base 2, and a conductive roller 4 mounted on the mounting base 2. A vertical long hole 5 is provided in the upper part of the mounting base 2. A lifting seat 6 with adjustable height is installed at the rear side of the mounting base 2, and a horizontal shaft 7 fixed to the lifting seat 6. The horizontal shaft 7 passes through the vertical long hole 5 and is connected to the conductive roller 4. It also includes an air nozzle 8 with a nozzle opening facing the strip workpiece 11 and an air pipe connected to the air nozzle 8 through an air compressor. An exhaust hole 9 is provided on the recovery tank 1 and is connected to the gas-liquid separator in the electroplating solution recovery equipment.

[0017] During the production process of the electroplating equipment, the strip workpiece 11 enters from the right end of the recovery tank 1, passes through the gap between the support roller 3 and the conductive roller 4 after being driven at a constant speed by two pressure rollers, and then exits from the left end of the recovery tank 1. Due to the support of the support roller 3 and the downward pressure of the conductive roller 4, the contact reliability between the conductive roller 4 and the strip workpiece 11 is relatively high, ensuring the stable operation of the electroplating process. Since the air nozzle 8 sprays high-speed air flow during operation, the electroplating solution remaining on the strip workpiece 11 is blown into the recovery tank 1, effectively avoiding the problems of wear between the washing cotton and the strip workpiece 11 and incomplete recovery of the electroplating solution. The recovery efficiency is high, solving the problem that the existing electroplating equipment needs to be frequently opened for maintenance, and the electroplating efficiency is significantly improved.

[0018] In this embodiment, the included angle between the nozzle opening direction of the air nozzle 8 and the advancing direction of the strip workpiece 11 is 20 degrees to 60 degrees. After adopting this structural design, the high-pressure gas ejected from the air nozzle 8 is reverse to the advancing direction of the strip workpiece 11, increasing the relative speed between the high-pressure gas and the strip workpiece 11, and making the cleaning and recovery of the electroplating solution remaining on the strip workpiece 11 more thorough, with a higher recovery efficiency.

[0019] In this embodiment, the number of the air nozzles 8 is two, and the two air nozzles 8 are respectively located on the upper and lower sides of the strip workpiece 11, so as to supplement the blowing of the positions that cannot be blown by one air nozzle 8, and the cleaning and recovery efficiency of the electroplating solution is higher.

[0020] In this embodiment, the conductive roller 4 is made of copper material, and the conductive roller 4 is electrically connected to the electroplating positive electrode or electroplating anode of the electroplating equipment through the horizontal shaft 7 and a wire.

[0021] In this embodiment, the recovery tank 1 includes a front baffle, a rear baffle 12, a bottom plate, and two side plates 13 connecting the front baffle and the rear baffle 12. The height of the front baffle is lower than that of the rear baffle 12. A reflux groove 14 with a lower front and higher rear is provided on the inner sides of the two side plates 13. A sealing rubber strip 15 is transversely arranged along the upper edge of the front baffle. Specifically, the recovery tank 1 further includes a cover plate 16 connected to the upper edges of the two side plates 13, and the lower edge of the cover plate 16 abuts against the sealing rubber strip 15. When the electroplating solution is blown off by the air nozzle 8, it will fly in the recovery tank 1 and then stay on the inner wall of the recovery tank 1. The design of the reflux groove 14 allows the electroplating solution staying on the inner wall of the recovery tank 1 and the cover plate 16 to gather as soon as possible and then flow back to the bottom of the recovery tank 1 from the lowest point of the reflux groove 14. The design of the sealing rubber strip 15 helps to prevent the electroplating solution from being discharged with the high-pressure gas and polluting the environment or being wasted, and it has strong practicability.
