Description

Technical Field

[0001] This application relates to the field of surface cleaning, and more particularly to an ultrasonic cleaning device. Background Technology

[0002] Ultrasonic cleaning technology is a precision cleaning method that utilizes high-frequency sound wave energy to generate physical effects in a liquid medium, efficiently removing contaminants from the surface of an object. In related technologies, when using an ultrasonic cleaner to clean the surface of a workpiece, a top-bottom cleaning method is typically employed. This involves setting up two ultrasonic cleaning devices arranged vertically opposite each other, and using a conveyor belt to transport the workpiece sequentially through the cleaning gap between the two ultrasonic cleaning devices along the conveyor belt's transport direction, thereby achieving the purpose of ultrasonic cleaning both the upper and lower surfaces of the workpiece.

[0003] Regarding the aforementioned technologies, the inventors believe that when the above-mentioned cleaning method is used to clean the surface of a workpiece, the track will interfere with the lower surface of the workpiece, which will result in incomplete cleaning of the lower surface. Utility Model Content

[0004] To address the issue of incomplete cleaning of the lower surface by the top and bottom cleaning modes, this application provides an ultrasonic cleaning device.

[0005] The ultrasonic cleaning equipment provided in this application adopts the following technical solution: An ultrasonic cleaning device includes a mounting frame, a support plate arranged parallel to the length of the mounting frame for abutting the lower end face of a workpiece, a first ultrasonic device arranged on one side of the support plate for ultrasonic cleaning one side surface of the workpiece, a second ultrasonic device arranged on the other side of the support plate for ultrasonic cleaning the other side surface of the workpiece, and a feeding mechanism arranged at one end of the support plate for conveying workpieces to the first and second ultrasonic devices; an ultrasonic channel for moving the workpiece is formed between the first and second ultrasonic devices; water baffle assemblies are respectively provided at the input and output ends of the ultrasonic channel; a drain outlet is provided at the bottom of the ultrasonic channel on the mounting frame, and a drain pipe for discharging cleaning fluid is provided at the drain outlet.

[0006] By adopting the above technical solution, when cleaning the surface of the workpiece, multiple workpieces are first placed sequentially at the input end of the support plate. Driven by the feeding mechanism, the ends of adjacent workpieces abut against each other and move along the length of the support plate into the ultrasonic channel. The first and second ultrasonic devices located on both sides of the workpiece perform ultrasonic cleaning on both sides of the workpiece. After cleaning, the workpiece moves at a constant speed in the ultrasonic channel under the abutment of the rear workpiece and is output from the output end of the support plate to the outside of the ultrasonic cleaning equipment. This achieves double-sided cleaning of the workpiece and improves the problem of incomplete cleaning of the lower surface in the top and bottom cleaning mode. Since the side walls of the first and second ultrasonic devices are in close contact with the left and right sides of the workpiece during the cleaning process, the water level of the cleaning fluid in the ultrasonic channel is stable at the height above the top of the workpiece. The baffle plate further reduces the rate of leakage of the cleaning fluid from both ends, which helps to improve the cleaning efficiency of the ultrasonic cleaning equipment on the surface of the workpiece.

[0007] Optionally, the first ultrasonic device includes a first outer cover and a first generator arranged on the side of the first outer cover away from the material support plate; the first outer cover forms a first water storage chamber, and the first outer cover has a first water inlet at the top for inputting cleaning fluid into the first water storage chamber; the first generator has a plurality of first vibration units spaced apart along the conveying direction of the workpiece, and the first outer cover has a plurality of first generating ports on the side facing the material support plate, penetrating the inner and outer surfaces and arranged directly opposite the first vibration units; the second ultrasonic device includes a second outer cover and a second generator arranged on the side of the second outer cover away from the material support plate; the second outer cover forms a second water storage chamber, and the second outer cover has a second water inlet at the top for inputting cleaning fluid into the second water storage chamber; the second generator has a plurality of second vibration units spaced apart along the conveying direction of the workpiece, and the second outer cover has a plurality of second generating ports on the side facing the material support plate, penetrating the inner and outer surfaces and arranged directly opposite the second vibration units.

[0008] By adopting the above technical solution, the specific structures of the first ultrasonic device and the second ultrasonic device are disclosed. When the first ultrasonic device is running, cleaning fluid is input into the first water storage chamber through the first water inlet, the first generator drives multiple first vibration units to vibrate, and the cleaning fluid is output to the surface of the workpiece through the first generating port, thereby realizing ultrasonic cleaning of one side of the workpiece surface. When the second ultrasonic device is running, cleaning fluid is input into the second water storage chamber through the second water inlet, the second generator drives multiple second vibration units to vibrate, and the cleaning fluid is output to the surface of the workpiece through the second generating port, thereby realizing ultrasonic cleaning of both sides of the workpiece surface.

[0009] Optionally, both the first ultrasonic device and the second ultrasonic device are slidably arranged along the length direction perpendicular to the material support plate. The mounting frame is provided with a first sliding assembly for driving the first ultrasonic device to slide and a second sliding assembly for driving the second ultrasonic device to slide. The first sliding assembly includes a first fixed base, a first sliding seat connected to the first ultrasonic device and slidably arranged on the first fixed base along the length direction perpendicular to the material support plate, and a first lead screw for driving the first sliding seat to move. The second sliding assembly includes a second fixed base, a second sliding seat connected to the second ultrasonic device and slidably arranged on the second fixed base along the length direction perpendicular to the material support plate, and a second lead screw for driving the second sliding seat to move.

[0010] By adopting the above technical solution, the first ultrasonic device is driven to slide along the length direction perpendicular to the support plate by the first sliding component, so that the outer end surface of the first outer cover and the side of the workpiece are always kept at a suitable distance; the second ultrasonic device is driven to slide along the length direction perpendicular to the support plate by the second sliding component, so that the outer end surface of the second outer cover and the side of the workpiece are always kept at a suitable distance; the first sliding component and the second sliding component respectively drive the first ultrasonic device and the second ultrasonic device to slide along the length direction perpendicular to the support plate, thereby realizing the adjustment of the ultrasonic channel width, which helps to improve the flexibility and applicability of ultrasonic cleaning of workpieces of different thicknesses.

[0011] Optionally, the baffle assembly includes a mounting bracket installed on the outer end of the second ultrasonic device, a first baffle that slides vertically on the mounting bracket, and a flexible extension baffle installed on the lower end of the first baffle; the mounting bracket has a strip-shaped hole extending in a vertical direction, the first baffle has a locking hole that mates with the strip-shaped hole, and a locking member for locking the first baffle to the mounting bracket is installed at the locking hole.

[0012] By adopting the above technical solution, the specific structure of the baffle assembly is disclosed. The baffle assembly reduces the overflow of cleaning fluid at the input and output ends of the ultrasonic channel. The first baffle can slide up and down along the mounting bracket and be locked by the locking device, which can flexibly adjust the relative height of the first baffle, thus helping to improve the adaptability to workpieces of different specifications. The setting of the extension baffle helps to further enhance the water blocking effect, while reducing the risk of wear caused by the collision between the upper end of the workpiece and the extension baffle.

[0013] Optionally, the feeding mechanism includes roller assemblies rotatably mounted on both sides of the material support plate, and a third sliding assembly that drives the roller assemblies to move along a length direction perpendicular to the material support plate; the roller assembly includes a vertically arranged rotating rod, a rotating wheel sleeved on the upper end of the rotating rod, and a drive motor connected to the lower end of the rotating rod and driving the rotating rod to rotate; the third sliding assembly includes a third fixed seat mounted on the mounting frame, a third sliding seat slidably arranged on the third fixed seat along a length direction perpendicular to the material support plate, and a third lead screw that drives the third sliding seat to move; the rotating rod is rotatably mounted on the third sliding seat.

[0014] By adopting the above technical solution, the rotating wheel of the roller assembly rotates under the drive of the rotating rod driven by the drive motor and pushes the workpiece to move, realizing the conveying of the workpiece to the first ultrasonic device and the second ultrasonic device. The third sliding component can drive the roller assembly to move along the direction perpendicular to the length of the support plate, which makes it easy to adjust the position of the roller assembly according to different workpiece sizes, and improve the applicability of the equipment and the flexibility of feeding.

[0015] Optionally, a limiting annular groove is formed on the outer side of the rotating wheel in the circumferential direction, and the mounting frame is provided with a limiting side plate for the rotating wheel to abut against the side facing the material support plate. The limiting side plate is provided with an arrangement through groove for the rotating wheel to rotate and an abutment part that cooperates with the limiting annular groove is provided in the middle of the arrangement through groove.

[0016] By adopting the above technical solution, the limiting ring groove on the outer side of the rotating wheel and the abutting part in the middle of the through groove of the limiting side plate can effectively reduce the risk of axial movement of the rotating wheel during rotation, which helps to improve the stability of the rotating wheel and thus ensures the smoothness of the feeding process.

[0017] Optionally, it also includes a filtration device for receiving the cleaning fluid output from the drainage pipe; the filtration device includes a filter housing, an extension plate arranged circumferentially on the top of the filter housing, and multiple filter components detachably installed on the top of the filter housing; a filter chamber is formed inside the filter housing; multiple filter ports are provided on the top of the filter housing for arranging the multiple filter components one by one; each filter component includes a mounting ring adapted to the filter port and a filter screen installed on the mounting ring; the filter housing has an output port at the lower end of the side wall for outputting the filtered cleaning fluid.

[0018] By adopting the above technical solution, the filtration device can receive the cleaning liquid output from the drainage pipe and filter the cleaning liquid using the filtration component. The filtered cleaning liquid is output from the output port, realizing the recycling of the cleaning liquid. When impurities in the filtration component clog the filter screen, the excess cleaning liquid will overflow from the filter port and flow to other filter ports and be filtered by the corresponding filtration component. The filtration component can be detached and installed on the top of the filter box, making it convenient to replace and clean the filtration component.

[0019] Optionally, the top of the filter housing is provided with an overflow port, the horizontal height of which is higher than the horizontal height of the filter port and lower than the upper edge height of the extension plate.

[0020] By adopting the above technical solution, when the water level of the cleaning liquid accumulated at the top of the filter box is higher than the upper edge of the overflow port, the excess cleaning liquid can be discharged from the overflow port, reducing the risk of cleaning liquid overflowing from the upper edge of the extension plate, while ensuring the normal operation of the filter assembly.

[0021] Optionally, it also includes a drying device arranged outside the output end of the material support plate for surface drying of the workpiece; the drying device includes a conveying base plate arranged at the output end of the material support plate and extending away from the material support plate, heating plates arranged vertically on both sides of the conveying base plate, and a limiting mechanism for limiting the workpiece to the left and right; the top surface height of the conveying base plate is the same as the top surface height of the material support plate; the limiting mechanism includes a limiting long plate arranged parallel to the length direction of the conveying base plate and a fourth sliding assembly for driving the limiting long plate to move in a direction perpendicular to the length direction of the conveying base plate; the fourth sliding assembly includes a fourth fixed seat arranged on the mounting frame, a fourth sliding seat connected to the limiting long plate and slidably arranged on the fourth fixed seat in a direction perpendicular to the length direction of the conveying base plate, and a fourth lead screw for driving the fourth sliding seat to move.

[0022] By adopting the above technical solution, after the workpiece is ultrasonically cleaned, the drying device can perform surface drying treatment on the workpiece. The workpiece moves smoothly to the drying area along the conveyor base plate under the drive of the feeding mechanism. The heating plates located on the left and right sides of the workpiece can effectively improve the drying efficiency. The fourth sliding component can flexibly adjust the position of the limiting plate to adapt to workpieces of different sizes, which helps to reduce the risk of the workpiece shifting left and right during the drying process.

[0023] Optionally, it also includes a drying mechanism arranged at the output end of the material support plate for drying the surface of the workpiece; the drying mechanism includes a first air knife, a second air knife arranged opposite to each other on both sides of the material support plate, a first air outlet pipe connected to the first air knife for outputting airflow, and a second air outlet pipe connected to the second air knife for outputting airflow; the first air knife has a vertically arranged first air duct on the side facing the material support plate; the second air knife has a vertically arranged second air duct on the side facing the material support plate.

[0024] By adopting the above technical solution, a drying mechanism is set at the output end of the material support plate. Airflow is output to the first air knife and the second air knife respectively through the first air outlet pipe connected to the first air knife and the second air outlet pipe connected to the first air knife. Air is blown to both sides of the workpiece through the vertically arranged first air channel and second air channel, which can dry the surface of the workpiece.
