Description

Technical Field

[0001] The invention relates to the technical field of automatic workpiece cleaning, and in particular to a rotary cleaning machine. Background Art

[0002] During the production process of the motor housing, when the housing is manufactured, some white debris often adheres to its surface. The sources of these debris are varied, and may include lubricant residues in the production process, metal particles in the cutting or grinding process, or even chemical reactions between dust particles in the air and the housing surface. The presence of these white debris not only affects the appearance quality of the motor housing, but more importantly, they may contain substances that are harmful to the performance of the motor, such as tiny metal particles. These particles may cause wear of the internal parts of the motor due to friction when the motor is running, thereby affecting the overall performance and life of the motor.

[0003] Traditional cleaning methods mainly rely on manual wiping or brushing, but this method has many shortcomings. First, manual cleaning is inefficient, especially in large-scale production environments where a large number of motor housings need to be cleaned. Manual operations are not only time-consuming and labor-intensive, but also costly. Second, manual cleaning can easily cause scratches on the surface of the motor housing, which not only affects the appearance, but may also become the source of noise and vibration when the motor is running, reducing the overall performance of the motor. In addition, scratches may also aggravate corrosion and aging of the motor housing surface, shortening the service life of the motor. Summary of the invention

[0007] Preferably, at least one of the cleaning rods is disposed at the rotation center of the cleaning rack, and the center axis of the first water outlet of the cleaning rod is disposed at an angle to the rotation center axis thereof, so as to clean the inside of the workpiece.

[0008] Preferably, the bottom cleaning assembly comprises a cleaning block, the cleaning block is rotatably connected to the supporting mechanism, the cleaning block is provided with a third water outlet hole connected to the circulating water tank, and the third water outlet hole is arranged toward the cleaning rack.

[0009] Preferably, the rotary cleaning machine is further provided with an air pump, and the cleaning mechanism is divided into two groups, wherein one group of the cleaning mechanisms is connected to the circulating water tank, and the other group of the cleaning mechanisms is connected to the air pump.

[0012] Preferably, the carrying mechanism also includes a carrying motor, the output shaft of the carrying motor is drivingly connected to the carrying plate, a plurality of positioning blocks are provided on the carrying plate, and the plurality of positioning blocks are spaced apart from the carrying assembly. The cleaning platform is provided with an identification module, the identification module is electrically connected to the carrying motor, and the identification module produces a moving path setting for the positioning block.

[0013] Preferably, the cleaning rack is provided with a plurality of second water outlet holes toward the bottom cleaning assembly, and the inner diameters of the first water outlet holes and the second water outlet holes are both in the range of 0.1 mm to 8 mm.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] (1) Through the coordinated work of the top cleaning component and the bottom cleaning component, the cleaning mechanism can clean the surface of the workpiece at different angles, thereby achieving comprehensive cleaning of the workpiece surface. This design can ensure that the cleaning liquid covers every corner of the workpiece, including hard-to-reach gaps and recesses. Compared with manual cleaning, there is less need for manual intervention, reducing the risk of incomplete cleaning or damage to the workpiece surface due to improper manual operation, and reducing the labor intensity of workers, which can significantly improve the efficiency and effect of cleaning;

[0016] (2) The cleaning rack and the cleaning rods can jointly construct a three-dimensional cleaning environment. When the cleaning rods rotate on the cleaning rack, since the central axis of the first water outlet is at an angle to the central axis of rotation, the water mist will be sprayed into the workpiece at a specific angle and path. For workpieces with complex internal structures, such as pipes, shells, etc., to adapt to different parts and shapes of the workpiece, this adaptability makes the solution more efficient and accurate in cleaning complex workpieces, ensuring that every corner and hard-to-reach area inside the workpiece can be fully cleaned, achieving a full range of cleaning effects;

[0017] (3) The cleaning mechanism rises, and the elastic force of the spring forces the cleaning jig to rise, so that the cleaning jig is separated from the receiving tank, and a gap is left between the cleaning jig and the cleaning platform, so that when the carrier plate rotates, the cleaning jig and the cleaning platform are prevented from interfering with each other. By avoiding interference and friction between the cleaning jig and the cleaning platform, this design reduces the risk of equipment failure, improves the reliability and stability of the equipment, and ensures the continuity and accuracy of the cleaning process;

[0018] (4) The electrical connection between the identification module and the carrier motor enables the cleaning process to be automatically controlled. When the identification module detects that the positioning block has reached the preset position, it sends a signal to the carrier motor to stop rotating or adjust the rotation speed, thereby ensuring that the workpiece can accurately enter the cleaning mechanism for cleaning. Through precise positioning and automatic control, the carrier plate can quickly move the workpiece from the initial position to the cleaning position, and then to the next station or recycling position. This efficient transmission method greatly shortens the cleaning cycle and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with specific embodiments:

[0029] refer to Figure 1As shown, a rotary cleaning machine includes a support frame 6, a cleaning platform 1, and a cleaning mechanism 2. The cleaning platform 1 is fixed on the support frame 6, and the carrying mechanism 4 is rotatably arranged on the cleaning platform 1 to carry the workpiece 100. The cleaning mechanism 2 includes a lifting assembly 21, a top cleaning assembly 22, and a bottom cleaning assembly 25. The lifting assembly 21 is fixedly connected to the cleaning platform 1 through the support frame 6, the telescopic end of the lifting assembly 21 is arranged toward the carrying mechanism 4, the top cleaning assembly 22 is fixed to the telescopic end of the lifting assembly 21, and the lifting assembly 21 is fixed to the protective cover 23. The bottom cleaning assembly 25 is rotatably connected to the cleaning platform 1, and the carrying mechanism 4 is located between the lifting assembly 21 and the bottom cleaning assembly 25 to carry the workpiece 100. When the lifting assembly 21 descends and the protective cover 23 abuts against the carrying mechanism 4, the protective cover 23 and the carrying mechanism 4 form a closed cleaning space 24, and the top cleaning assembly 22 and the bottom cleaning assembly 25 clean the workpiece 100 in the cleaning space 24.

[0030] refer to Figure 2 As shown, specifically, the lifting assembly 21 includes a lifting motor 211 and a support member. The lifting motor 211 is fixedly mounted on the support frame 6, and the output shaft of the lifting motor 211 is telescopically arranged in the vertical direction toward the bearing mechanism 4. The output shaft of the lifting motor 211 is fixedly connected to a bracket 212, and the bracket 212 is rotatably connected to a first coupling pipe 221, and the rotation center axis of the first coupling pipe 221 is vertically arranged. The rotary cleaning machine includes a water pump 8, a circulating water tank 3 and a water pipe. The water pump 8 is connected to the circulating water tank 3 to provide power. The water outlet of the circulating water tank 3 is connected to one end of the first coupling pipe 221 through the water pipe, and the water pipe is rotatably connected to the connection point of the first coupling pipe 221. More specifically, the end of the water pipe away from the circulating water tank 3 is fixedly connected to the bracket 212 to ensure that the first coupling pipe 221 can rotate.

[0031] The first coupling tube 221 is provided with an external tooth portion on its outer circumference, and the bracket 212 is fixed to the top cleaning motor 222. The top cleaning motor 222 is transmission-connected to the external tooth portion of the first coupling tube 221 through a gear rack to drive the first coupling tube 221 to rotate.

[0032] refer to Figure 3As shown, the top cleaning assembly 22 includes a cleaning rack 223 and a plurality of cleaning rods 224. The cleaning rack 223 is fixedly connected to an end of the first coupling pipe 221 away from the water pipe, and the cleaning rack 223 is communicated with the first coupling pipe 221. In this embodiment, the cleaning rack 223 is horizontally arranged, and the plurality of cleaning rods 224 are fixedly connected to the cleaning rack 223 in the vertical direction, and the cleaning rods 224 are communicated with the cleaning rack 223. The cleaning rods 224 are provided with a first water outlet 2241, and the cleaning rack 223 is provided with a second water outlet 2231. The first water outlet 2241 and the second water outlet 2231 are both communicated with the hole of the first coupling pipe 221, and the water of the circulating water tank 3 passes through the first water outlet 2241 and then the second water outlet 2231 to clean the workpiece 100.

[0033] In this embodiment, the cleaning rack 223 is a horizontal rod-shaped structure, and there are three cleaning rods 224. Specifically, one end of the three cleaning rods 224 is connected to the cleaning rack 223, and the other end extends toward the supporting mechanism 4. One of the cleaning rods 224 is arranged at the rotation center of the cleaning rack 223, that is, the rotation center axis of the cleaning rod 224 is coaxial with the rotation center axis of the cleaning rack 223. When the lifting assembly 21 drives the cleaning assembly 22 to descend, the cleaning rod 224 is inserted into the motor housing to clean the inner wall of the workpiece 100; the other two are respectively arranged at both ends of the cleaning rack 223, that is, the three cleaning rods 224 are distributed along the length direction of the cleaning rack 223.

[0034] In other variations, the cleaning rack 223 has a disc-shaped structure, wherein one cleaning rod 224 is disposed at the center of the cleaning rack 223 , and the other cleaning rods 224 are distributed in a circular array at the edge of the cleaning rack 223 .

[0035] Preferably, the central axis of the first water outlet 2241 on the cleaning rod 224 is set at an angle relative to the central axis of the cleaning rod 224, and more preferably, the angle is 45°. By cleaning the outer wall and inner wall of the workpiece 100 through the inclined first water outlet 2241, the water mist can be guided to be shot at the workpiece 100 at a specific angle, thereby ensuring that the water vapor can evenly cover the surface of the workpiece 100, reducing blind spots, optimizing the impact force and coverage of the water mist, and making the water mist more effective in removing dirt and residues on the surface of the workpiece 100, improving the cleaning efficiency, and improving the cleaning effect. The second water outlet 2231 on the cleaning rack 223 is vertically set. By cleaning the outer end face of the workpiece 100 through the vertically set second water outlet 2231, it can be ensured that the water mist is directly and accurately shot at the top of the workpiece 100, thereby providing a better cleaning effect and making the top of the workpiece 100 cleaner and tidier.

[0036] In this embodiment, the inner diameters of the first water outlet 2241 and the second water outlet 2231 are both in the range of 0.1mm-8mm. Specifically, taking the inner diameter of the first water outlet 2241 as 0.1mm as an example, the inner diameter is extremely small, so that the water flow can be highly concentrated to form a fine water column, which helps to accurately clean tiny stains and gaps on the motor housing, reduce the accumulation of scale in the first water outlet 2241, and maintain smooth water flow. Taking the inner diameter of the first water outlet 2241 as 8mm as an example, the increase in water flow can provide sufficient water pressure and flow for cleaning, significantly improve cleaning efficiency, and complete large-area cleaning work in a short time.

[0037] Specifically, the protective cover 23 is a hollow cylindrical structure, the top of the protective cover 23 is bolted to the bottom of the bracket 212, the cleaning frame 223 and the cleaning rod 224 are located in the protective cover 23, and the bottom end surface of the protective cover 23 is open.

[0038] refer to Figure 4 and Figure 5 As shown, the cleaning platform 1 is concave with a receiving tank 11, and the bottom cleaning assembly 25 is arranged in the receiving tank 11. The bottom cleaning assembly 25 includes a cleaning block 251 and a bottom cleaning motor 252. The cleaning block 251 is rotatably arranged in the receiving tank 11. Specifically, the cleaning platform 1 is rotatably connected with a second coupling pipe 253, which vertically passes through the cleaning platform 1. The second coupling pipe 253 is located at one end of the receiving tank 11 and is fixedly connected to the cleaning block 251. A section of the second coupling pipe 253 located outside the receiving tank 11 is connected to the water outlet of the circulating water tank 3 through a water pipe. The bottom cleaning motor 252 is fixedly arranged on the cleaning platform 1, and the bottom cleaning motor 252 is transmission-connected to the second coupling pipe 253 through a belt drive. The bottom cleaning motor 252 drives the second coupling pipe 253 to rotate, thereby driving the cleaning block 251 to rotate in the receiving tank 11.

[0039] A plurality of third water outlet holes 2511 are formed on the top end surface of the cleaning block 251 , and the third water outlet holes 2511 are connected to the water outlet of the circulating water tank 3 through the second coupling pipe 253 , that is, the circulating water tank 3 cleans the bottom inner wall of the workpiece 100 through the third water outlet holes 2511 .

[0040] A drain port 12 is provided at the bottom of the receiving tank 11, and the drain port 12 is connected to the water inlet of the circulating water tank 3 through a water pipe, and the waste water collected after cleaning is recycled into the circulating water tank 3. Specifically, a filter is provided in the circulating water tank 3, and the recycled water can be input to the top cleaning component 22 and the bottom cleaning component 25 again after filtering to clean the workpiece 100.

[0041] refer to Figure 1As shown, specifically, the bearing mechanism 4 is provided with a bearing plate 41 and a bearing motor 42, the bearing motor 42 is fixedly mounted on the support frame 6, the output shaft of the bearing motor 42 is fixedly connected to the rotation center of the bearing plate 41 through a rotating shaft, the bearing plate 41 is rotationally connected to the cleaning platform 1, and there is a spacing between the bearing plate 41 and the cleaning platform 1, so that the bearing plate 41 can rotate smoothly, avoiding the risk of interference of the cleaning platform 1 and the structure on the cleaning platform 1 with the bearing plate 41. In this embodiment, the bearing plate 41 is provided with a plurality of work holes 411, the work holes 411 are distributed in a circular array with the rotation center of the bearing plate 41 as the center, and the work holes 411 are through holes in the vertical direction. The cleaning platform 1 is provided with a receiving groove 11 corresponding to the work hole 411. Specifically, the number of the work holes 411 is three, and the number of the corresponding receiving grooves 11 is three, and the receiving grooves 11 correspond to the work holes 411 one by one.

[0042] refer to Figure 6 As shown, the supporting mechanism 4 also includes a supporting component 43, and the supporting component 43 includes a cleaning jig 431 and a plurality of springs 432. The cleaning jig 431 is slidably arranged in the working hole 411 along the vertical direction. The bottom edge of the cleaning jig 431 is extended outward to be provided with an extension, and the extension is supported on the supporting plate 41. A plurality of springs 432 are arranged between the extension and the supporting plate 41. One end of the spring 432 is fixedly connected to the cleaning jig 431, and the other end of the spring 432 is fixedly connected to the supporting plate 41.

[0043] The cleaning mechanism 2 descends, the protective cover 23 is plugged into the cleaning jig 431, and the protective cover 23 and the cleaning jig 431 are sealed and connected via a sealing ring, the cleaning mechanism 2 continues to descend, the cleaning jig 431 is plugged into the inner wall of the receiving tank 11, and the cleaning jig 431 is sealed and connected to the inside of the receiving tank 11 via a sealing ring. Thus, a sealed cleaning space 24 is formed to ensure the cleaning effect of the internal cleaning mechanism 2.

[0044] The cleaning mechanism 2 rises, and the elastic force of the spring 432 forces the cleaning jig 431 to rise, so that the cleaning jig 431 is separated from the receiving groove 11, and a gap is left between the cleaning jig 431 and the cleaning platform 1, so that when the supporting plate 41 rotates, the cleaning jig 431 and the cleaning platform 1 are prevented from interfering.

[0045] Specifically, the cleaning fixture 431 includes a support tube 4311 and a frame 4312. The support tube 4311 is hollow and round, and the outer circumference of the support tube 4311 is slidably arranged with the carrier plate 41, and the edge is arranged at the upper edge of the support tube 4311 protruding toward the outer circumference, and the spring 432 is arranged at the protruding part of the support tube 4311 to support the support tube 4311. The frame 4312 is fixed to the inner wall of the support tube 4311, the frame 4312 is parallel to the bearing platform, and the frame 4312 is a hollow structure to ensure that the medium can flow smoothly in the support tube 4311.

[0046] The frame 4312 is fixed with a plurality of positioning pins 433 , which are distributed in a central circumferential array of the frame 4312 . The positioning pins 433 limit the outer peripheral side of the workpiece 100 , and are used to limit and position the workpiece 100 to prevent the workpiece 100 from moving or shaking in the horizontal direction.

[0047] The supporting mechanism 4 also includes a positioning assembly 5, which includes an identification module 51 and a plurality of positioning blocks 52. The identification module 51 is fixed on the cleaning platform 1, and the plurality of positioning blocks 52 are fixed on the supporting plate 41 in a circular array, and the positioning blocks 52 are spaced apart from the supporting assembly 43. In the present embodiment, there are three positioning blocks 52, and the positioning blocks 52 are fixed between two adjacent working holes 411. The distances between the three positioning blocks 52 and the rotation center of the supporting plate 41 are the same. The identification end of the identification module 51 is arranged toward the supporting plate 41. More specifically, the identification module 51 is arranged toward the rotation path direction of the positioning block 52 to identify the positioning block 52, so as to achieve the effect of accurately positioning the workpiece 100. The identification module 51 is electrically connected to the carrying motor 42. Specifically, the carrying motor 42 drives the carrying plate 41 to rotate. When the identification module 51 identifies the positioning block 52, the identification module 51 sends a transmission signal to the carrying motor 42, and the carrying motor 42 forces the carrying plate 41 to stop rotating, so that the cleaning component 22 stops accurately between the bottom cleaning component 25 and the top cleaning component 22, so that the workpiece 100 can be cleaned in the next step.

[0048] In this embodiment, there are two groups of cleaning mechanisms 2, and the two groups of cleaning mechanisms 2 perform two cleaning processes on the workpiece 100. Specifically, the two groups of cleaning mechanisms 2 are fixed on the support frame 6, and one cleaning mechanism 2 corresponds to one receiving slot 11 in a one-to-one manner in the vertical direction. A rotary cleaning machine also includes an air pump 7 and an air pipe, the air pump 7 is connected to the top cleaning component 22 and the bottom cleaning component 25 of one group of cleaning mechanisms 2 through the air pipe, and the circulating water tank 3 is connected to the top cleaning component 22 and the bottom cleaning component 25 of the other group of cleaning mechanisms 2 through the water pipe. More specifically, the workpiece 100 is first cleaned by water mist and then dried by air washing.

[0049] Implementation principle: The operator places the workpiece 100 on the cleaning jig 431, the frame 4312 is supported at the bottom of the workpiece 100, and the positioning pin 433 limits the outer peripheral side of the workpiece 100, thereby limiting and positioning the workpiece 100. The carrying motor 42 drives the carrying plate 41 to rotate, thereby driving the workpiece 100 to rotate. When the recognition module 51 recognizes the positioning block 52, the carrying motor 42 forces the carrying plate 41 to stop, and the cleaning jig 431 carrying the workpiece 100 is located between the top cleaning component 22 and the bottom cleaning component 25. The lifting motor 211 drives the top cleaning component 22 and the protective cover 23 to descend. During this process, the protective cover 23 is sealed and connected to the top of the cleaning jig 431, and the cleaning jig 431 is pressed down and sealed and connected to the inner wall of the receiving tank 11, thereby forming a sealed cleaning space 24. Since the two groups of cleaning mechanisms 2 are carried out synchronously, that is, when one cleaning mechanism 2 washes the workpiece 100 with water, the next cleaning mechanism 2 dries the other workpiece 100 that has completed water washing. Taking the cleaning mechanism 2 for washing the workpiece 100 as an example, the cleaning rod 224 located in the middle is inserted into the workpiece 100 to clean the inside of the workpiece 100, the cleaning rod 224 located at the edge of the cleaning rack 223 cleans the outside of the workpiece 100, the cleaning rack 223 cleans the top end surface of the workpiece 100, and the cleaning block 251 cleans the inner top wall of the workpiece 100. The top cleaning motor 222 drives the cleaning rod 224 and the cleaning rack 223 to rotate, and the bottom cleaning motor 252 drives the cleaning block 251 to rotate, so as to clean every corner of the workpiece 100.
