Description

Technical Field

[0001] The present application belongs to the technical field of cleaning machines, and in particular, relates to an ultrasonic cleaning machine. Background Art

[0002] The working principle of the ultrasonic cleaning machine is that the high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated to the medium, i.e. the cleaning solvent. The ultrasonic wave radiates forward in the cleaning liquid in a sparse and dense manner, causing the liquid to flow and generate tens of thousands of tiny bubbles with a diameter of 50-500μm. The tiny bubbles in the liquid vibrate under the action of the sound field.

[0003] The existing Chinese patent with publication number CN218191413U discloses an ultrasonic cleaning machine, including a main body, an opening on one side of the main body, a sealing door is installed on the left side of the opening, a buckle is installed on the right side of the sealing door, and an outer sealing frame is provided on the inner edge of the sealing door, an inner sealing frame is provided on the outer edge of the opening, a sealing connection groove is provided on the inner side of the outer sealing frame, mounting grooves are provided at both ends of the inner sealing frame, the sealing connection groove and the mounting groove are arranged correspondingly, an airbag ring is installed inside the mounting groove, one end of the airbag ring is connected to an air pump, and a clamping mechanism is installed on one edge of the main body.

[0004] Although the above-mentioned ultrasonic cleaning machine can take and place objects from the side, saving time and labor, and has good sealing performance and high practicality, it is necessary to pre-treat the workpiece before cleaning it to initially clean the dirt, and then manually transfer it to the cleaning machine for cleaning. Subsequent rinsing and drying also require manual transfer, which has high labor costs, low work efficiency, and single function. Utility Model Content

[0005] The purpose of this application is to provide an ultrasonic cleaning machine to address the above-mentioned technical problems, which can automatically pre-treat the workpiece to initially clean the dirt, and can automatically rinse and dry the workpiece after cleaning to reduce labor costs, improve work efficiency, and have more functions.

[0006] The present application provides an ultrasonic cleaning machine, including a cleaning machine body, wherein the cleaning machine body includes:

[0007] A pre-treatment mechanism, including a cleaning roller, a loading platform and a conveyor belt;

[0008] A cleaning tank, including a water inlet, a drain hole and a transport device;

[0009] Spray drying mechanism, including a spray nozzle and a hot air gun;

[0010] Activity door, including air bag ring;

[0011] An ultrasonic cleaning component is placed on the lower side of the top wall of the cleaning tank;

[0012] Sealing frame;

[0013] The movable door cooperates with the cleaning machine body, the movable door cooperates with the sealing frame through the airbag ring, and the loading platform cooperates with the conveyor belt.

[0014] In the present technical solution, the workpiece is preliminarily cleaned by a pretreatment mechanism, and the workpiece is placed on a stage. The workpiece is moved to a cleaning tank through the cooperation between the stage and the conveyor belt. During the movement, the cleaning rollers on both sides of the conveyor belt rotate continuously, thereby preliminarily removing dirt on the workpiece to facilitate subsequent cleaning by an ultrasonic cleaning component. After the stage moves to the movable door, the movable door is triggered to move, and the workpiece is pushed from the stage to a transport device in the cleaning tank. After that, the movable door and the stage are reset, and the movable door is sealed with the airbag ring and the sealing frame to prevent water in the cleaning tank from overflowing. At this time, water begins to flow into the water inlet hole in the cleaning tank, and the ultrasonic wave is triggered at the same time. The cleaning component works to complete the cleaning of the workpiece. After cleaning, the workpiece is moved to the spray drying mechanism through the transportation device. The spray drying mechanism is provided with a nozzle and a hot air gun. The nozzle first flushes away the residual dirt on the workpiece, and then the hot air gun is started to dry the outer surface of the workpiece. When the transportation device starts to move, the drainage holes in the cleaning tank also start to drain. Combined with the above-mentioned technical features, the cleaning machine body can automatically clean the dirt on the workpiece preliminarily, and can automatically rinse and dry the workpiece after cleaning. This process does not require manual operation, which greatly reduces labor costs and improves work efficiency. The cleaning machine body has more functions and broadens the scope of application.

[0015] Furthermore, the pre-processing mechanism comprises:

[0016] Support frame;

[0017] A sponge connected to the cleaning roller;

[0018] A first motor connected to the cleaning roller;

[0019] A material pushing device, which is installed on the loading platform;

[0020] Wherein, the first motor is installed on the support frame, and the cleaning roller is rotationally connected to the support frame.

[0021] In the present technical solution, a support frame is arranged in the pretreatment mechanism, a first motor is installed on the support frame, and the cleaning roller is rotatably connected to the support frame. The cleaning roller is rotated on the support frame by the first motor. A sponge is installed on the cleaning roller. The sponge has a strong dirt removal ability and a soft material, which is convenient for cleaning irregularly shaped workpieces to enhance the cleaning ability of the cleaning roller. A pushing device is installed on the loading platform. The pushing device is started after the movable door is displaced, thereby pushing the workpiece to the transport device of the cleaning tank to complete subsequent processing. After that, the conveyor belt drives the empty loading platform to reset.

[0022] Furthermore, the pushing device comprises:

[0023] A sliding block including a second motor;

[0024] A push plate, which is rotatably connected to the sliding block via a second motor;

[0025] A first hydraulic cylinder, a movable end of which is connected to the sliding block, and a fixed end of which is connected to the loading platform;

[0026] Wherein, the sliding block cooperates with the loading platform.

[0027] In the present technical solution, a sliding block and a push plate are arranged on the pushing device, and the push plate is rotatably connected to the sliding block through the second motor. When the pushing device is working, the second motor is started to rotate the push plate, so that the push plate is rotated from a horizontal position to a vertical position to facilitate pushing the workpiece. At the same time, the first hydraulic cylinder works. Since the movable end of the first hydraulic cylinder is connected to the sliding block, the fixed end is connected to the loading platform, and the sliding block cooperates with the loading platform, the movable end of the first hydraulic cylinder drives the sliding block to move on the loading platform. During the displacement process, the push plate pushes the workpiece to the transportation device of the cleaning tank, and then the sliding block and the push plate are reset.

[0028] Furthermore, the transport device comprises:

[0029] Lifting platform;

[0030] A second hydraulic cylinder, whose movable end is rotatably connected to the lifting platform, and whose fixed end is rotatably connected to the side wall of the cleaning tank;

[0031] Waterproof motor, including lead screw;

[0032] The lifting platform cooperates with the screw rod, and the waterproof motor cooperates with the side wall of the cleaning tank.

[0033] In the present technical scheme, a lifting platform is arranged in the transport device, and the workpiece is pushed onto the lifting platform by the push plate. After the workpiece is cleaned by the ultrasonic cleaning component, the waterproof motor is triggered to rotate, and the waterproof motor is fixed to the side wall of the cleaning tank when powered on, and the waterproof motor then drives the lifting platform to move horizontally through the cooperation between the lifting platform and the screw rod. After the lifting platform moves to the end of the cleaning machine body, the waterproof motor is powered off, so that it can move at the side wall of the cleaning tank, and at the same time triggers the second hydraulic cylinder to work, and the movable end of the second hydraulic cylinder is rotationally connected to the lifting platform, and the fixed end is rotationally connected to the side wall of the cleaning tank, so as to facilitate the second hydraulic cylinder to move with the lifting platform. When the second hydraulic cylinder drives the lifting platform to rise, the waterproof motor can also rise with the lifting platform. After the lifting platform rises to the spray drying mechanism, the workpiece is rinsed and dried by the spray drying mechanism. After the processed workpiece is taken away by the staff, the lifting platform is reset through the second hydraulic cylinder and the waterproof motor.

[0034] Furthermore, the spray drying mechanism comprises:

[0035] First contact point;

[0036] Water tank, including water pump;

[0037] Wherein, the lifting platform is provided with a second contact, and the water pump is started after the second contact contacts the first contact, and the nozzle is connected to the water tank through the water pump.

[0038] In the present technical solution, a water tank with a water pump is arranged on the spray drying mechanism, and the nozzle is connected to the water tank through the water pump. The first contact in the spray drying mechanism is placed at the top of the cleaning tank, and a second contact is arranged on the lifting platform. When the lifting platform drives the workpiece to the top of the cleaning tank, the workpiece is not affected by the liquid in the cleaning tank. At the same time, the second contact contacts the first contact, and the water pump is started to trigger the nozzle to work. The nozzle is evenly distributed above the workpiece, and the workpiece can be fully rinsed. After the nozzle is finished working, the hot air gun is triggered to work, and the hot air gun is evenly distributed on the side of the workpiece, and the workpiece can be fully dried.

[0039] Furthermore, the cleaning roller comprises:

[0040] Sand strips are seamed between the sand strips and the sponge.

[0041] In this technical solution, by sewing sand strips on the sponge, the sand strips have a better cleaning effect than the sponge, and after the sand strips are sewn on the surface of the sponge, the strength and toughness are improved, which can effectively reduce the probability of the sponge being damaged during the cleaning process, thereby extending the service life of the cleaning roller.

[0042] The beneficial effects of this application are:

[0043] 1. The pretreatment mechanism can perform preliminary cleaning on the workpiece to facilitate the subsequent ultrasonic cleaning component to clean it. After that, the workpiece is moved to the spray drying mechanism through the transportation device to rinse and dry the workpiece, so that the cleaning machine body can automatically clean the dirt on the workpiece preliminarily, and can automatically rinse and dry the workpiece after cleaning, reducing labor costs and improving work efficiency.

[0044] 2. The push plate in the pushing device pushes the workpiece from the loading platform to the transport device of the cleaning tank through the extension and retraction of the first hydraulic cylinder. Then the sliding block and the push plate are reset, and the conveyor belt drives the empty loading platform to reset, which is convenient for the cleaning machine body to clean the next part, thereby improving work efficiency.

[0045] 3. After the workpiece is cleaned, the waterproof motor rotates to drive the lifting platform to move horizontally. Then the lifting platform rises to the spray drying mechanism through the second hydraulic cylinder. At this time, the first contact at the top of the cleaning tank contacts the second contact of the lifting platform, triggering the nozzle and the hot air gun to complete the rinsing and drying of the workpiece.

[0062] The workpiece is preliminarily cleaned by the pretreatment mechanism 200, and the workpiece is placed on the stage 220. The workpiece is moved to the cleaning tank 300 through the cooperation between the stage 220 and the conveyor belt 230. During the movement, the cleaning rollers 210 on both sides of the conveyor belt 230 rotate continuously, thereby preliminarily removing the dirt on the workpiece, so as to facilitate the subsequent cleaning by the ultrasonic cleaning component 120. After the stage 220 moves to the movable door 110, the movable door 110 is triggered to move, and the workpiece is pushed from the stage 220 to the transportation device 330 of the cleaning tank 300. After that, the movable door 110 and the stage 220 are reset, and the movable door 110 is sealed by the airbag ring 111 and the sealing frame 130 to prevent the water in the cleaning tank 300 from overflowing. At this time, the water inlet hole 310 in the cleaning tank 300 begins to Water enters, and at the same time, the ultrasonic cleaning component 120 is triggered to work to complete the cleaning of the workpiece. After the cleaning is completed, the workpiece is moved to the spray drying mechanism 400 through the transportation device 330. The spray drying mechanism 400 is provided with a nozzle 410 and a hot air gun 420. The nozzle 410 first flushes away the dirt remaining on the workpiece, and then the hot air gun 420 is started to dry the outer surface of the workpiece. When the transportation device 330 starts to move, the drainage hole 320 in the cleaning tank 300 also starts to drain. Combined with the above-mentioned technical features, the cleaning machine body 100 can automatically clean the dirt on the workpiece preliminarily, and can automatically rinse and dry the workpiece after the cleaning is completed. No manual operation is required in this process, which greatly reduces labor costs and improves work efficiency. In addition, the cleaning machine body 100 has more functions and broadens the scope of application.

[0069] By setting a support frame 240 in the pretreatment mechanism 200, installing the first motor 260 on the support frame 240, and making the cleaning roller 210 rotatably connected to the support frame 240, the cleaning roller 210 rotates on the support frame 240 through the first motor 260, and a sponge 250 is installed on the cleaning roller 210. The sponge 250 has a strong ability to remove dirt and is made of a soft material, which is convenient for cleaning irregularly shaped workpieces to enhance the cleaning ability of the cleaning roller 210, and a pushing device 270 is installed on the stage 220. After the movable door 110 is displaced, the pushing device 270 is started to push the workpiece to the transportation device 330 of the cleaning tank 300 to complete subsequent processing, and then the conveyor belt 230 drives the empty stage 220 to reset.

[0070] Furthermore, the pushing device 270 includes:

[0071] The sliding block 271 includes a second motor 274;

[0072] A push plate 272, which is rotatably connected to the sliding block 271 via a second motor 274;

[0074] The sliding block 271 cooperates with the stage 220 .

[0075] By arranging a sliding block 271 and a push plate 272 on the pushing device 270, the push plate 272 is rotatably connected to the sliding block 271 through the second motor 274.

At the same time, the first hydraulic cylinder 273 works. Since the movable end of the first hydraulic cylinder 273 is connected to the sliding block 271, the fixed end is connected to the worktable 220, and the sliding block 271 cooperates with the worktable 220, the movable end of the first hydraulic cylinder 273 drives the sliding block 271 to move on the worktable 220, and the push plate 272 pushes the workpiece to the transportation device 330 of the cleaning tank 300 during the displacement process, and then the sliding block 271 and the push plate 272 are reset.

[0080] The lifting platform 331 cooperates with the screw rod 334 , and the waterproof motor 333 cooperates with the side wall of the cleaning tank 300 .

[0081] By setting a lifting platform 331 in the transport device 330, the workpiece is pushed onto the lifting platform 331 by the push plate 272. After the workpiece is cleaned by the ultrasonic cleaning component 120, the waterproof motor 333 is triggered to rotate, and the waterproof motor 333 is fixed to the side wall of the cleaning tank 300 when powered on. The waterproof motor 333 then drives the lifting platform 331 to move horizontally through the cooperation between the lifting platform 331 and the screw rod 334. After the lifting platform 331 moves to the end of the cleaning machine body 100, the waterproof motor 333 is powered off, so that it can move at the side wall of the cleaning tank 300, and at the same time the second hydraulic cylinder 3 is triggered. 32 works, the movable end of the second hydraulic cylinder 332 is rotatably connected to the lifting platform 331, and the fixed end is rotatably connected to the side wall of the cleaning tank 300, so that the second hydraulic cylinder 332 can move with the lifting platform 331. When the second hydraulic cylinder 332 drives the lifting platform 331 to rise, the waterproof motor 333 can also rise with the lifting platform 331. After the lifting platform 331 rises to the spray drying mechanism 400, the workpiece is rinsed and dried by the spray drying mechanism 400. After the processed workpiece is taken away by the staff, the lifting platform 331 is reset through the second hydraulic cylinder 332 and the waterproof motor 333.
