Description

Technical Field

[0001] The present application relates to the field of electroplating technology, and in particular to an electroplating device. Background Art

[0002] Electroplating is a processing method that uses the principle of electrolysis to form a dense metal or alloy layer on the surface of the workpiece to improve the strength, wear resistance and corrosion resistance of the workpiece. There are two main ways of electroplating: rack plating and barrel plating. Rack plating is to hang large parts on a hanger by clamping, and then immerse the hanger in a processing tank to electroplate large parts, while barrel plating is suitable for electroplating small parts. The small parts are loaded into a drum, and then the drum is immersed in the processing tank. At the same time, the drum is rotated so that the small parts in the drum can be turned over, so that the small parts can be fully electroplated.

[0003] A Chinese patent with announcement number CN113957514A discloses a lifting mechanism for a nickel plating production line, including a lifting end, a connecting structure is arranged on the bottom end of the lifting end, a storage basket is installed outside the connecting structure, the connecting structure includes two vertical plates, a connecting plate is fixedly installed on the top of the two vertical plates, a baffle and a bending angle are installed on the lower end of the vertical plates, the storage basket abuts against the bending angle and the baffle, and rotating disks are rotatably installed on the opposite surfaces of the two vertical plates, and the baffle and the bending angle are fixedly connected to the rotating disk.

[0004] During the use of the above technology, when the storage basket is lifted from one electroplating pool, some of the electroplating liquid of the pool will adhere to the storage basket.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] An embodiment of the present application discloses an electroplating device.

[0033] Reference Figure 1 A plating device includes a frame 1, on which a vertical gantry 2 is horizontally slidably arranged, and a sliding member 3 driving the sliding of the gantry 2 is arranged, and the sliding member 3 includes a sliding motor 31 bolted to the gantry 2 and electrically connected to a control system, and a roller 32 is coaxially welded to the output shaft of the sliding motor 31, and a wheel rail 33 is bolted to the frame 1, and the roller 32 rolls on the wheel rail 33, and a plurality of electroplating pools 4 are bolted to the frame 1, and the plurality of electroplating pools 4 are evenly arranged along the sliding direction of the gantry 2.

A driving member 6 for driving the hanging bracket 5 to move is arranged on the gantry 2. The driving member 6 includes a lifting motor 61 bolted to the top of the gantry 2 and electrically connected to the control system. The lifting motor 61 adopts a forward and reverse motor in the prior art.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A transmission shaft 62 is coaxially welded to the output shaft of the lifting motor 61, and two wire wheels 15 are coaxially bolted to the transmission shaft 62. A pull rope 63 is wound on the wire wheel 15. The pull rope 63 adopts a steel wire rope in the prior art. An avoidance slot 16 for the pull rope 63 to pass through is opened on the gantry 2. A bearing plate 14 is fastened to the end of the pull rope 63 facing away from the transmission shaft 62, and a hanger 5 is bolted to the bearing plate 14 on the side of the pull rope 63 facing away from the gantry 2.

[0036] The worker starts the sliding motor 31 through the control system, and the sliding motor 31 drives the roller 32 to rotate in the forward direction. The reaction force between the roller 32 and the wheel rail 33 causes the gantry 2 to slide along the length direction of the wheel rail 33 until the gantry 2 slides to just above the electroplating pool 4. At this time, the control system stops supplying power to the sliding motor 31, and then the control system starts the lifting motor 61. The output shaft of the lifting motor 61 rotates in the reverse direction. The output shaft of the lifting motor 61 drives the transmission shaft 62 to rotate in the reverse direction. The transmission shaft 62 unwinds the pull rope 63, and the hanger 5 is gradually lowered into the electroplating pool 4.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A liquid removal component 7 for removing electrolyte attached to the rack 5 is arranged on the gantry 2. The liquid removal component 7 includes a liquid removal part 71 for removing electrolyte on the rack 5 and a liquid collecting part 72 for collecting electrolyte detached from the rack 5. The liquid removal part 71 includes a fan 711 bolted to the gantry 2 and electrically connected to the control system, and the air outlet of the fan 711 faces the rack 5.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The liquid collecting part 72 includes a vertical corrugated sleeve 721 bolted to the gantry 2, the corrugated sleeve 721 is made of flexible material, the air outlet of the fan 711 faces the inner side of the corrugated sleeve 721, the corrugated sleeve 721 is used to be sleeved on the bracket 5, and a liquid collecting ring 722 is bonded to the end of the corrugated sleeve 721 facing away from the gantry 2, and a drainage pipe 723 is connected to the liquid collecting ring 722. The drainage pipe 723 is made of flexible material, and a drainage groove 724 is opened on the frame 1 along the sliding direction of the gantry 2, and the liquid outlet end of the drainage pipe 723 points to the drainage groove 724.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A guide plate 13 is obliquely bonded inside the corrugated sleeve 721, and the guide plate 13 is obliquely arranged toward the hanger 5 along the direction from the corrugated sleeve 721 to the hanger 5. An end ring 8 is bolted to the end of the corrugated sleeve 721 facing away from the gantry 2, and a slider 9 is welded on the end ring 8. A slide groove 10 for the slider 9 to slide is opened on the gantry 2 along the direction from the corrugated sleeve 721 to the hanger 5.

[0040] Reference Figure 1 , Figure 2 and Figure 3 A vertical lifting screw 11 is rotatably arranged on the gantry 2, the slider 9 is threadedly connected to the lifting screw 11, a driving motor 12 electrically connected to the control system is bolted to the gantry 2, and the lifting screw 11 is coaxially welded to the output shaft of the driving motor 12.

[0041] When the electroplating of the workpiece on the hanger 5 is completed, the worker starts the lifting motor 61 through the control system. The output shaft of the lifting motor 61 drives the transmission shaft 62 to rotate forward. The transmission shaft 62 reels the pull rope 63. The hanger 5 is gradually pulled up and separated from the electroplating pool 4. After the hanger 5 rises to a certain height position, the control system starts the drive motor 12.

[0042] The output shaft of the driving motor 12 rotates forward, and the driving motor 12 drives the lifting screw 11 to rotate forward, so that the lifting screw 11 drives the slider 9 to slide vertically downward, the slider 9 drives the end ring 8 to descend, and the end ring 8 drives the corrugated sleeve 721 to gradually expand downward and be sleeved outside the bracket 5.

[0043] At this time, the control system starts the fan 711, and the fan 711 blows away the plating liquid attached to the hanger 5 and the workpiece. A part of the blown plating liquid adheres to the inner wall of the corrugated sleeve 721, and the other part will fall back into the electroplating pool 4 below it. As the fan 711 blows the hanger 5 for a longer time, the plating liquid attached to the inner wall of the corrugated sleeve 721 gradually gathers in the liquid collecting ring 722, and is discharged from the drain pipe 723 to the drain trough 724 on the frame 1, and is discharged from the drain trough 724 to the collection box.

[0044] The implementation principle of an electroplating equipment in an embodiment of the present application is as follows: a worker starts the sliding motor 31 through the control system, and the sliding motor 31 drives the roller 32 to rotate in the forward direction. The reaction force between the roller 32 and the wheel rail 33 causes the gantry 2 to slide along the length direction of the wheel rail 33 until the gantry 2 slides to just above the electroplating pool 4. At this time, the control system stops supplying power to the sliding motor 31, and then the control system starts the lifting motor 61. The output shaft of the lifting motor 61 rotates in the reverse direction. The output shaft of the lifting motor 61 drives the transmission shaft 62 to rotate in the reverse direction. The transmission shaft 62 unwinds the pull rope 63, and the hanger 5 is gradually lowered into the electroplating pool 4.

[0045] When the electroplating of the workpiece on the hanger 5 is completed, the worker starts the lifting motor 61 through the control system. The output shaft of the lifting motor 61 drives the transmission shaft 62 to rotate forward. The transmission shaft 62 reels the pull rope 63. The hanger 5 is gradually pulled up and separated from the electroplating pool 4. After the hanger 5 rises to a certain height position, the control system starts the drive motor 12.

[0046] The output shaft of the driving motor 12 rotates forward, and the driving motor 12 drives the lifting screw 11 to rotate forward, so that the lifting screw 11 drives the slider 9 to slide vertically downward, the slider 9 drives the end ring 8 to descend, and the end ring 8 drives the corrugated sleeve 721 to gradually expand downward and be sleeved outside the bracket 5.

[0047] At this time, the control system starts the fan 711, and the fan 711 blows away the plating liquid attached to the hanger 5 and the workpiece. A part of the blown plating liquid adheres to the inner wall of the corrugated sleeve 721, and the other part will fall back into the electroplating pool 4 below it. As the fan 711 blows the hanger 5 for a longer time, the plating liquid attached to the inner wall of the corrugated sleeve 721 gradually gathers in the liquid collecting ring 722, and is discharged from the drain pipe 723 to the drain trough 724 on the frame 1, and is discharged from the drain trough 724 to the collection box.
