Description

Technical Field

[0001] This utility model belongs to the technical field of degreasing devices, and particularly relates to a degreasing device for electroplating pretreatment. Background Technology

[0002] Electroplating for hardware products involves applying a layer of metal to a conductive material using electrolysis. A common problem is coating peeling, primarily caused by oil or foreign matter on the surface of the hardware substrate that cannot be completely removed during electroplating, preventing the formation of a plating layer. Traditional processes often use acid to pretreat the workpiece, but the biggest drawback is that residual acid after pickling and rust removal is difficult to rinse off from complex parts. This can lead to rust along the seams after electroplating, damaging the surface of the plating layer.

[0003] Chinese utility model patent CN220999846U discloses an oil removal device for electroplating, comprising: a base, with support plates fixedly mounted on both sides of the upper surface of the base, and a rotating shaft rotatably mounted above each support plate; this utility model, by incorporating a cleaning cylinder, gears, and incomplete gears, allows for the cleaning of electroplated parts. Water and cleaning solution are added to the cleaning cylinder, and the electroplated parts are placed inside. A first motor is then activated, driving the incomplete gears to rotate. When the locking teeth on the incomplete gears engage with the gears, the incomplete gears drive the gears to rotate, causing the rotating shaft to rotate the cleaning cylinder. A torsion spring is in a torsional state, achieving the effect of rotating the cleaning cylinder. The electroplated parts inside the cleaning cylinder tumble and roll, passing through the vertical rods and bristles on the cleaning components. The bristles clean the oil stains on the outer surface of the electroplated parts, resulting in excellent cleaning performance.

[0004] However, the above-mentioned device has the following technical problems in actual use:

[0005] 1. The above-mentioned device can cause the workpiece inside to shake by swinging the cleaning cylinder left and right, thereby cleaning the surface of the workpiece with the help of the brush bristles. However, since the cleaning cylinder contains degreasing liquid and the cleaning cylinder has a semi-open structure, the degreasing liquid inside shakes along with the cleaning cylinder when it shakes left and right. When the swing amplitude of the cleaning cylinder is too large, the degreasing liquid may overflow from the top of the cleaning cylinder. The above-mentioned device lacks a collection device for the overflowing degreasing liquid, which leads to the spillage and waste of the degreasing liquid.

[0006] Second, the above-mentioned device cannot guarantee that the workpiece is turned over in the cleaning drum, so the brush bristles cannot be used to brush the oil film adhering to each surface of the workpiece, which affects the actual brushing effect of the above-mentioned device. Utility Model Content

[0007] This utility model provides an oil removal device for electroplating pretreatment, aiming to solve the problems mentioned in the background art. In the above-mentioned devices, the cleaning cylinder has a semi-open structure, and when the cleaning cylinder shakes from side to side, some of the degreasing liquid may overflow from its top. The above-mentioned devices lack a collection device for the overflowing degreasing liquid, which easily leads to waste of degreasing liquid. At the same time, the above-mentioned devices cannot ensure that the workpiece is turned over in the cleaning cylinder, and cannot use the brush bristles to brush the oil film adhering to the various surfaces of the workpiece.

[0008] This utility model is implemented as follows: an oil removal device for electroplating pretreatment includes: a base plate on which two vertical plates are symmetrically and vertically fixed; a cleaning tank is fixedly installed between the two vertical plates; a cleaning chamber is formed in the top wall of the cleaning tank; a rotating shaft is rotatably connected between the two vertical plates and located above the cleaning tank; a driving assembly is fixedly connected to the side wall of one of the vertical plates to control the rotation of the rotating shaft; a brushing assembly extending into the cleaning chamber is provided on the outer wall of the rotating shaft between the two vertical plates; and collection boxes are fixedly connected to both side walls of the cleaning tank, with an opening at the top of the collection box. The device includes a collection port connecting to its interior, which is used to collect the degreasing liquid that overflows from the cleaning chamber. In this design, collection boxes are fixedly installed on both side walls of the cleaning chamber, and the top of the collection box with a collection port extends to the top wall of the collection box and is located on one side of the collection chamber. When the drive assembly controls the rotating shaft to rotate, the rotating shaft drives the brushing assembly fixed on it to swing in the cleaning chamber, thereby brushing the workpiece. The degreasing liquid driven by the brushing assembly swings in the cleaning chamber. When the amplitude is too large, the degreasing liquid overflows from the top of the cleaning chamber and enters the collection box through the collection port, thus using the collection box to collect the degreasing liquid again and avoid waste of the degreasing liquid.

[0009] Furthermore, each of the collection boxes is equipped with multiple return pipes on its side wall, and each return pipe is connected to a storage box at its end. The storage box is located above the cleaning gun. When the pump is turned on, the degreasing liquid in the collection box will be discharged back into the cleaning chamber through the return pipe, realizing the secondary use of the degreasing liquid.

[0010] In addition, the device has multiple protrusions evenly spaced along the arc surface of the inner wall of the cleaning chamber. When the fixed rod collides with the workpiece, it will work with the brush bristles to agitate the workpiece. The agitated workpiece will then come into contact with the protrusions, thus turning the workpiece over. This achieves the purpose of brushing the various surfaces of the workpiece by the reciprocating oscillation of the brush bristles.

[0011] Preferably, the drive assembly includes: a motor fixedly mounted on one side wall of the upright plate, a drive gear fixedly mounted on the output end of the motor, and a driven gear fixedly connected to the outer wall of one end of the rotating shaft, with the drive gear and the driven gear meshing together; in this scheme, when the output end of the motor rotates, it drives the drive gear to rotate, and the drive gear then transmits the rotational kinetic energy to the driven gear meshing with it. Since the driven gear and the end of the rotating shaft are fixedly connected, the driven gear then drives the rotating shaft to rotate at multiple angles. By utilizing the forward and reverse rotation of the motor output end, the reciprocating oscillation of the brushing assembly on the rotating shaft is driven.

[0012] Preferably, the brushing assembly includes: a plurality of fixed rods fixedly installed on the outer wall of the rotating shaft between the two upright plates; the plurality of fixed rods are equally spaced along the length of the rotating shaft; a gap is formed between each pair of adjacent fixed rods for the workpiece to pass through; and a brush plate is fixedly installed on the side wall of each pair of adjacent fixed rods, and the brush plate is provided with bristles. In this scheme, when the rotating shaft rotates, it will drive the plurality of fixed rods on its outer wall to swing in its rotation direction. After the fixed rods contact the workpiece in the cleaning chamber, they will drive the workpiece to move in the cleaning chamber. At the same time, the workpiece will also pass through the gap between two adjacent fixed rods, and the brush bristles will brush at least two surfaces of the workpiece passing through the gap.

[0013] Preferably, the inner wall of the cleaning chamber is provided with multiple protrusions at equal intervals, and the length of each protrusion is consistent with the inner length of the cleaning chamber. In this scheme, the multiple protrusions are arranged at equal intervals along the arc-shaped inner wall of the cleaning chamber. When the fixing rod contacts the workpiece and moves it along the inner wall of the cleaning chamber, the workpiece will contact the protrusions. The cooperation between the protrusions and the fixing rod drives the workpiece to flip over, so that the subsequent brush bristles can be used to brush the various surfaces of the workpiece.

[0014] Preferably, each collection box is L-shaped, with its top extending to the top wall of the cleaning box and located on one side of the cleaning chamber. The collection port is opened on the top side wall of the collection box, and an isolation screen is detachably embedded in the collection port. In this scheme, the top of the collection box is located on the top wall of the cleaning box, and a collection port is opened on its side wall facing the cleaning chamber. The length of the collection box is the same as the length of the cleaning box. The collection box can intercept the overflowing degreasing liquid to prevent it from splashing, and can also collect part of the degreasing liquid, so that the overflowing degreasing liquid enters the collection box through the collection port, thus completing the collection of the overflowing degreasing liquid, preventing it from polluting the working environment, and reducing the amount of manual cleaning required later.

[0015] It should be explained that the isolation screen set inside the collection port can intercept the workpiece, preventing it from being carried by the degreasing liquid into the collection box.

[0016] Preferably, the top of the cleaning tank is further fixed with two mounting brackets, which are symmetrically arranged on both sides of the rotating shaft. Each mounting bracket has: a column vertically fixed to the top wall of the cleaning tank; two columns symmetrically arranged on both sides of the cleaning chamber; a horizontal plate fixed between the tops of the two columns; and multiple storage tanks fixedly installed at equal intervals along the length of the bottom wall of the horizontal plate. Each storage tank is connected to the corresponding collection tank through a return pipe. A nozzle is fixedly installed on the bottom wall of each storage tank, and a pump body is fixedly installed on each return pipe. In this scheme, when the overflowing degreasing liquid reaches a certain amount, the pump body can be turned on to pump the degreasing liquid in the collection tank into the top storage tank through the return pipe. Then, it flows into the nozzle through the storage tank and is returned to the cleaning chamber by the nozzle, thus completing the secondary use of the degreasing liquid and avoiding waste.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a degreasing device for electroplating pretreatment.

[0018] 1. This device has collection boxes fixedly installed on both side walls of the cleaning chamber. The top of the collection box has a collection port that extends to the top wall of the collection box and is located on one side of the collection chamber. When the drive component controls the rotating shaft to rotate, the rotating shaft drives the brushing component fixed on it to swing in the cleaning chamber to brush the workpiece. The degreasing liquid driven by the brushing component swings in the cleaning chamber. When the amplitude is too large, the degreasing liquid overflows from the top of the cleaning chamber and enters the collection box through the collection port. The collection box is used to collect the degreasing liquid again to avoid waste of the degreasing liquid.

[0019] 2. In this device, multiple protrusions are evenly spaced along the arc-shaped surface of the inner wall of the cleaning chamber. When the fixed rod collides with the workpiece, it will work with the brush bristles to agitate the workpiece. The agitated workpiece will then come into contact with the protrusions, thus turning the workpiece over. This achieves the purpose of brushing the various surfaces of the workpiece by the reciprocating oscillation of the brush bristles. Attached Figure Description
