Technical Field

[0001] This invention relates to the field of PGTVD vacuum coating technology, and more specifically to a PGTVD vacuum coating workpiece cleaning device. Background Technology

[0002] PGTVD is a gas-phase pressurized transport controllable directional deposition technology. After electroplating, the coated workpiece needs to be cleaned by a cleaning device. However, the existing cleaning method is generally water rinsing, but water rinsing has low efficiency and may leave electroplating solution residue on the surface of the coated workpiece, which will affect the next processing of the coated workpiece. Summary of the Invention

[0003] To address this issue, the present invention provides a PGTVD vacuum coated workpiece cleaning device. The user pulls a movable frame to open multiple clamping plates, places multiple coated workpieces inside multiple positioning sleeves, and then reverses the movable frame to clamp and position the workpieces. Simultaneously, a drive motor is activated to activate multiple cleaning brushes to clean the workpieces. This solves the problem that existing cleaning methods typically involve water rinsing, which is inefficient and may leave residual plating solution on the workpiece surface, affecting subsequent processing.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a PGTVD vacuum coating workpiece cleaning device, comprising two positioning frames, both of which are circular in structure, and two supports are fixedly connected to the bottom of each of the two positioning frames. A clamping mechanism is provided inside the positioning frame and is used to position and clamp the coated workpiece.

[0007] Preferably, a first sprocket is fixedly sleeved on the outer side of each of the two second rotating rods, and a second sprocket is fixedly sleeved on the outer end of each of the plurality of winding wheels. A chain is sleeved on the outer side of the first sprocket and the second sprocket, and the first sprocket and the second sprocket are connected by a chain drive.

[0008] Preferably, the clamping mechanism further includes a gear ring, which has multiple first gears inside. The multiple first gears are respectively fixedly sleeved on the outside of the first rotating rod, and the two gear rings are respectively disposed on the inside of the two positioning frames.

[0009] Preferably, each of the two gear rings is fixedly connected to a movable frame at its top, and each of the two movable frames is fixedly connected to a T-shaped slider at its outer end. Each of the two positioning frames has a T-shaped groove at its top, and the two T-shaped sliders are respectively embedded in the two T-shaped grooves.

[0010] Preferably, the brushing mechanism further includes a reciprocating lead screw, which is fixedly sleeved on the outside of the drive shaft. A sliding block is sleeved on the outside of the reciprocating lead screw, and the sliding block is connected to the reciprocating lead screw through a ball screw pair.

This addresses the problem of existing cleaning methods, which typically involve water rinsing, having low efficiency and leaving residual plating solution on the workpiece surface, thus affecting subsequent processing. This invention significantly improves the efficiency of scrubbing coated workpieces. Furthermore, the multiple clamping plate design allows for simultaneous cleaning of multiple workpieces, greatly reducing cleaning costs. In addition, the device adopts a second gear and toothed plate design, which makes the cleaning brush rotate automatically when it brushes the workpiece left and right, so that the cleaning brush can clean the coated workpiece more thoroughly and greatly avoid the residue of electroplating solution.
