Description

Technical Field

[0001] The utility model relates to the technical field of using ultrasonic waves to clean parts, in particular to an automatic ultrasonic cleaning device. Background Art

[0002] The ultrasonic cleaning device uses ultrasound to create local tensile stress in the liquid and form negative pressure. The reduction in pressure causes the gas originally dissolved in the liquid to become supersaturated and escape from the liquid as small bubbles. The strong tensile stress "teares" the liquid into a cavity, which is called cavitation. It can quickly remove attachments on the surface of the material and is widely used in the pharmaceutical, machinery, and service industries.

[0003] At present, ultrasonic cleaning machines have become commonly used equipment in industry for quickly and efficiently removing residual oil stains, oxides and other contaminants on the surface of metal parts and raw materials processed by machinery and pressure. However, the existing cleaning equipment has a relatively low degree of automation, which seriously affects the cleaning efficiency.

[0036] See also Figures 1 to 8In an embodiment of the utility model, an automated ultrasonic cleaning device includes a frame 90, and a feeding assembly 10, a handling robot 20, a lifting robot 40 and a cleaning tank 60 installed on the frame 90; the feeding assembly 10 transports a tray 92 containing parts to be washed into the cleaning device, the handling robot 20 is provided with a transverse movement portion 21 and a grasping portion 30, the transverse movement portion 21 is movably connected to the frame 90, the grasping portion 30 is movably connected to the transverse movement portion 21, the grasping finger 34 of the grasping portion 30 is used to grasp the tray 92, and the transverse movement portion 21 moves it to the top of the cleaning tank 60; the lifting robot 40 is provided with a lifting carrier 44, the grasping finger 34 puts the tray 92 into the lifting carrier 44, and the lifting robot 40 drives the lifting carrier 44 to move downward so that it is immersed in the liquid inside the cleaning tank 60; the cleaning tank 60 is provided with an ultrasonic transducer 63, so as to perform ultrasonic cleaning operation on the parts to be washed immersed in the liquid.

[0037] Specifically, ultrasonic cleaning equipment is usually provided with a cleaning tank 60 and an ultrasonic transducer 63, and the cleaning liquid in the cleaning tank 60 is cavitated by the ultrasonic transducer 63, so that it can quickly remove the attachments on the surface of the parts and realize the cleaning operation of the parts. However, the cleaning liquid is usually harmful to the human body, so it is not convenient to perform manual operation, and the manual operation is relatively slow. In order to improve the cleaning efficiency of the parts in the factory, it is preferred to set an automated cleaning device, and use the automated handling manipulator 20 and the lifting manipulator 40 to form a mutual cooperation, so that the tray 92 containing the parts to be washed, which is transported into the feeding assembly 10, can be grasped and placed in the cleaning tank 60, so that the ultrasonic transducer 63 in the cleaning tank 60 can perform corresponding ultrasonic cleaning on the parts in the cleaning liquid. After the cleaning is completed, the tray 92 is taken out by the lifting manipulator 40 and the handling manipulator 20, and transported to the next station. Then the automated cleaning of the parts is realized, and the cleaning efficiency is improved.

[0038] like Figure 1 and Figure 2 As shown, preferably, the feed assembly 10 is provided with a feed conveying part 11, a feed rising part 15 and a feed carrier 18. The tray 92 loaded with parts to be washed is transported to the position of the feed rising part 15 by the feed conveying part 11. The feed carrier 18 is fixedly connected to the driving end of the feed rising part 15. The feed rising part 15 drives the feed carrier 18 to move upward by a certain distance, so that the tray 92 falls into the feed carrier 18, and finally continues to rise by a certain distance, so that the tray 92 is raised to the grabbing position of the grabbing fingers 34, so that the grabbing fingers 34 grab the tray 92.

The feed riser 15 is provided with a feed cylinder 16 and a feed sensor 17 respectively fixed to the frame 90. The feed carrier 18 is fixed to the drive shaft of the feed cylinder 16, so that the feed cylinder 16 can drive the feed carrier 18 to move upward, thereby transporting the tray 92 to the gripping position of the gripping finger 34. The feed sensor 17 is used to sense whether there is a tray 92 being transported above the feed carrier 18, so as to feedback to the feed riser 15 so that it can move upward, thereby lifting the tray 92 upward. Preferably, the feed lifting part 15 is respectively provided with two groups of feed carriers 18, feed cylinders 16 and feed sensors 17, and only after there are trays 92 above the two groups of feed carriers 18 will they move upward at the same time, so that the two trays 92 are moved upward to the position of the grabbing fingers 34 at the same time, so that the grabbing fingers 34 can grab the two trays 92 at the same time, thereby improving the operating efficiency.

[0040] like Figure 2 and Figure 3 As shown, preferably, the transverse moving part 21 is provided with a transverse moving rack 22, a transverse moving motor 23, a transverse moving slide 24 and a transverse moving slot 25, the transverse moving rack 22 and the transverse moving slide 24 are respectively fixed to the frame 90, the transverse moving motor 23 and the transverse moving slot 25 are respectively fixed to the transverse moving part 21, the transverse moving slot 25 and the transverse moving slide 24 cooperate with each other to form a sliding connection, the transmission shaft of the transverse moving motor 23 forms a transmission connection with the transverse moving rack 22, so that the transverse moving motor 23 is operated to drive the transverse moving part 21 to move laterally along the transverse moving slide 24.

[0041] Specifically, the transverse slide rail 24 is preferably arranged on the upper part of a crossbeam of the frame 90, so that the transverse slide groove 25 can be mounted on the transverse slide rail 24 from above, so that the weight of the entire transverse portion 21 and the grabbing portion 30 can be transferred to the transverse slide rail 24, and the transverse movement of the entire transverse portion 21 and the grabbing portion 30 can be achieved. The transverse portion 21 can also be provided with a corresponding vertical bracket 26, so that the vertical bracket 26 extends downward and forms a fixed connection with the grabbing portion 30. The transverse portion 21 mainly moves the grabbing portion 30 laterally, so that the tray 92 grabbed by it can be transferred between the feeding assembly 10, the cleaning tank 60 and the next external station.

[0042] like Figure 3 and Figure 4As shown, preferably, the grabbing portion 30 is provided with a grabbing slide rail 31, a grabbing groove 32 and a grabbing cylinder 33, the grabbing cylinder 33 and the grabbing slide rail 31 are respectively fixedly connected to the grabbing portion 30, the grabbing groove 32 forms a fixed connection with the grabbing finger 34, the grabbing groove 32 and the grabbing slide rail 31 cooperate with each other to form a sliding connection, one end of the grabbing finger 34 is fixedly connected to the driving end of the grabbing cylinder 33, and the other end thereof is used to grab the tray 92.

[0043] Specifically, the gripping part 30 may also be provided with a transverse bracket 35, and the transverse bracket 35 is fixedly connected to the vertical bracket 26 of the transverse moving part 21, so as to move laterally synchronously with the vertical bracket 26 of the transverse moving part 21. The gripping slide rail 31 and the gripping cylinder 33 may be fixedly connected to the transverse bracket 35, and the gripping chute 32 and the gripping fingers 34 are movably connected to the transverse bracket 35, and under the drive of the gripping cylinder 33, the gripping fingers 34 can perform a gripping operation on the tray 92. Preferably, the gripping part 30 may be provided with three groups of gripping fingers 34, gripping cylinders 33 and gripping chute 32, respectively, so as to perform a gripping operation on three groups of trays 92 at the same time. The gripping part 30 adjacent to the feeding assembly 10 is set as the first gripping group, the middle gripping part 30 is set as the second gripping group, and the gripping part 30 away from the feeding assembly 10 is set as the third gripping group. The first grabbing group can grab the tray 92 from the position of the feeding assembly 10 and move it to the rough washing tank 61 for the first rough washing operation; the second grabbing group can grab the tray 92 from the position of the rough washing tank 61 and move it to the fine washing tank 62 for the second fine washing operation; then the third grabbing group can grab the tray 92 from the position of the fine washing tank 62 and move it to the next workstation outside for subsequent operations.

[0044] Secondly, since the tray 92 and the parts thereon grabbed from the cleaning tank 60 are prone to leave some cleaning liquid, which is inconvenient for the operation of the subsequent workstations, a wind knife assembly 80 can be set in the third grabbing group to blow and remove water from the tray 92 and the parts. For example, a first wind knife 81 and a wind knife cylinder 82 are set, the first wind knife 81 is fixedly connected to the driving end of the wind knife cylinder 82, and one end of the wind knife cylinder 82 is fixedly connected to the grabbing bracket of a grabbing finger 34 of the third grabbing group, and the other end can be movably connected to the grabbing bracket of another grabbing finger 34. The wind knife cylinder 82 is preferably set as a rodless cylinder, and its driving end can be used to move the first wind knife 81 to a certain distance left and right in the third grabbing group, so that the first wind knife 81 can blow and remove water from the liquid on the tray 92 and the parts.

[0045] like Figure 5 and Figure 6As shown, preferably, the lifting robot 40 is provided with a lifting screw 41, a lifting motor 42 and a lifting bracket 43, the lifting motor 42 is fixedly connected to the frame 90, the lifting screw 41 is movably connected to the frame 90 and forms a transmission connection with the lifting motor 42, one end of the lifting bracket 43 is sleeved on the lifting screw 41 and forms a transmission connection, and the other end thereof is fixedly connected to the lifting carrier 44, so that the lifting motor 42 drives the lifting screw 41 to rotate, thereby driving the lifting bracket 43 to move up and down synchronously, and then driving the lifting carrier 44 to move up and down.

[0046] Specifically, the lifting screw 41 and the lifting bracket 43 are preferably connected by a thread, so that the lifting bracket 43 can bear a certain weight, so that the tray 92 and the parts can be moved up and down. Secondly, since the lifting carriage 44 needs to move downward and penetrate into the liquid in the cleaning tank 60, the lifting bracket 43 needs to be set to have a certain length. In order to prevent the relatively long lifting bracket 43 from affecting the lifting screw 41, a lifting roller 45 can also be set at one end of the lifting bracket 43 where the lifting carriage 44 is installed, so that the lifting roller 45 can abut against the inner wall of the cleaning tank 60 and roll thereon, thereby balancing the pulling force formed by the lifting carriage 44 on the lifting bracket 43. Of course, in order to prevent the inner wall of the cleaning tank 60 from being affected, a rolling bar 46 can also be set on the inner wall of the cleaning tank 60, so that the lifting roller 45 abuts against the rolling bar 46 and rolls.

[0047] like Figure 5 and Figure 6 As shown, preferably, the lifting manipulator 40 is also provided with a tilting manipulator 50, and the tilting manipulator 50 is provided with a tilting cylinder 51, a tilting connecting rod 52 and a tilting carrier 53, the tilting cylinder 51 is fixedly connected to the lifting bracket 43, one end of the tilting connecting rod 52 is fixedly connected to the driving end of the tilting cylinder 51, and the other end thereof is rotatably connected to the tilting carrier 53, one end of the tilting carrier 53 is rotatably connected to the tilting connecting rod 52, and the other end thereof is rotatably connected to the lifting carrier 44, so that the tilting cylinder 51 is operated, and the tilting connecting rod 52 is driven to drive the tilting carrier 53 to rotate a certain angle around one end thereof, so that the tilting carrier 53 can be tilted a certain angle.

[0048] Specifically, in order to tilt the tray 92 and pour out the residual liquid inside the tray 92, the tilting cylinder 51 can be used to drive the tilting carrier 53 to tilt at a certain angle, so as to pour out the corresponding residual liquid. Preferably, one end of the tilting carrier 53 located on the diagonal line can be rotatably connected to the lifting carrier 44, and the other end can be rotatably connected to the tilting connecting rod 52. Figure 5 As shown, preferably, the connection between the tilting carrier 53 and the lifting carrier 44 can adopt a rotating shaft connection or a loose-leaf connection in the prior art.

[0049] In addition, combined with the cooperation between the lifting robot 40 and the tilting robot 50, the tray 92 can also be subjected to enhanced motion operations such as throwing motion or shaking motion, so that the parts inside the tray 92 can produce certain displacements, flipping and other movements, so that each angle or each surface or each gap can be cleaned by the liquid driven by the ultrasonic transducer 63, thereby improving the cleanliness of the cleaning.

[0050] like Figure 6 and Figure 7 As shown, preferably, the cleaning tank 60 is provided with a rough cleaning tank 61 and a fine cleaning tank 62, and cleaning liquid and an ultrasonic transducer 63 are respectively provided inside the rough cleaning tank 61 and the fine cleaning tank 62, the rough cleaning tank 61 is used to perform a first rough cleaning operation on the parts in the tray 92, and the fine cleaning tank 62 is used to perform a second fine cleaning operation on the parts in the tray 92.

The washing tank 60 is also provided with a water inlet pipe 94 and a waste water pipe 93, so that the washing liquid can be input and the used liquid can be discharged. At the position of the fine washing tank 62 near the next station, a second air knife 83 can also be provided, so that the tray 92 and the parts moving to the next station are blown and dehydrated again, so as to further reduce the influence of the liquid on the next station.

[0052] like Figure 7 As shown, preferably, a first transducer 64, a second transducer 65, a third transducer 66 and a liquid level sensor 67 are further provided in the cleaning tank 60, the first transducer 64 and the third transducer 66 are respectively installed at both ends of the cleaning tank 60, the second transducer 65 is installed at the bottom of the cleaning tank 60, and the liquid level sensor 67 is fixedly connected to the side of the cleaning tank 60 for sensing the height of the liquid level in the cleaning tank 60.

[0053] Specifically, in order to improve the cleaning effect, multiple ultrasonic transducers 63 can be arranged in the cleaning tank 60 to clean the parts from multiple angles or directions. The liquid level sensor 67 can sense the water level of the cleaning liquid in the cleaning tank 60, thereby ensuring that the cleaning liquid does not overflow due to excess or does not have a corresponding cleaning effect due to insufficient excess.

[0054] like Figure 7As shown, preferably, it also includes a water tank 70, in which a water pump, a filter assembly 75 and a water level sensor 78 are provided. The water pump is used to transport the cleaning liquid in the water tank 70 to the cleaning tank 60; the filter assembly 75 is used to filter the liquid entering the water tank 70 to improve its cleaning performance; the water level sensor 78 is used to sense the water level in the water tank 70.

[0055] Specifically, the water storage tank 70 may be provided with a first water tank 71 and a second water tank 73, and may also be provided with a first water pump 72 and a second water pump 74. Preferably, the used cleaning liquid in the cleaning tank 60 may also enter the second water tank 73 through the waste water pipe 93 at the bottom of the cleaning tank 60 for filtration, and then the second water pump 74 extracts the liquid in the second water tank 73 that has been filtered for the first time into the first water tank 71 for the second filtration, and then the first water pump 72 may extract the cleaning liquid in the first water tank 71 that has been filtered for the second time, and flow it into the cleaning tank 60 through the water inlet pipe 94 for reuse. It is understandable that a sewage pipe 95 may also be provided at the bottom of the water storage tank 70 to remove the sewage or impurities left in the water storage tank 70 after long-term operation. It is understandable that the filter assembly 75 may use a product of a corresponding filter material in the prior art that is specifically used for filtering cleaning liquid.

[0056] Secondly, the water level sensor 78 can sense the water level of the cleaning liquid in the water tank 70, so as to ensure that the cleaning liquid does not overflow due to excess, or affect the cleaning efficiency due to insufficient amount.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
