Description

Technical Field

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

[0002] In the field of motor manufacturing and application, the motor housing, as the core component of the motor, not only carries various mechanical and electronic components inside the motor, but also bears the important responsibility of protecting these components from the external environment. The design of the motor housing often needs to take into account structural strength, heat dissipation performance and installation convenience.

[0003] The outer end face of the motor housing is often designed to be uneven. On the one hand, the uneven surface can increase the contact area between the motor housing and other components, improve the stability and reliability of the installation, and prevent loosening due to vibration or external force; on the other hand, the specific concave and convex structure can also be used as a positioning or guiding mark to help workers quickly and accurately find the installation position during the installation process, greatly improving assembly efficiency. In addition, for some special application scenarios, the uneven outer end face may also be designed with heat dissipation grooves or ventilation holes to enhance the heat dissipation performance of the motor and ensure that the motor can maintain a stable temperature when running under high load.

[0004] Due to the complex surface morphology, traditional cleaning methods often cannot effectively reach all recessed and raised areas, causing dust, oil and other pollutants to easily accumulate in these areas. The accumulated dust and oil will cover the heat dissipation structure (such as heat dissipation slots, ventilation holes), hindering the effective dissipation of heat, causing the internal temperature of the motor to rise, affecting the heat dissipation performance of the motor. The conductive substances in the dust and oil may penetrate into the electrical connections inside the motor, causing short circuits or reduced insulation performance, increasing the risk of motor failure.

[0021] like Figure 1 As shown, a cleaning machine includes a carrier 1 and a workbench 2. The carrier 1 has a chamber 11 therein. The workbench 2 is rotatably connected to the bottom of the chamber 11 of the carrier 1. The workbench 2 is used to support a motor housing 100. A lifting mechanism 3 is fixedly arranged on the top of the chamber 11 of the carrier 1. The lifting mechanism 3 moves in a vertical direction toward or away from the workbench 2. An upper cleaning assembly 4 is fixedly arranged at the end of the lifting mechanism 3. The lifting mechanism 3 drives the upper cleaning assembly 4 to approach the motor housing 100 located on the workbench 2 to clean the surface of the motor housing 100.

[0022] The bottom of the chamber 11 of the carrier 1 is configured as a plane. Preferably, the workbench 2 is a disc structure, and the workbench 2 is connected to the bottom of the chamber 11 of the carrier 1 through a motor. The carrier 1 is fixed with a protective ring 12, the central axis of the protective ring 12 is coaxial with the rotational central axis of the workbench 2, the inner wall of the protective ring 12 abuts against the outer wall of the workbench 2, and a gap is left between the bottom of the workbench 2 and the carrier 1 to avoid wear and tear between the bottom of the workbench 2 and the carrier 1.

[0023] like Figure 2 As shown, the workbench 2 is provided with a plurality of through holes 21, and the plurality of through holes 21 are distributed in a circular array with the rotation center of the workbench 2 as the center. In this embodiment, the workbench 2 is provided with six through holes 21, all of which are used to place the motor housing 100. The lifting mechanism 3 drives the upper cleaning assembly 4 to cooperate with the through holes 21 to form six stations on the carrier 1. The six stations are distributed around the rotation center of the workbench 2, including a loading station 91, a rough washing station 92, a fine washing station 93, a blowing station 94, a drying station 95 and a vacuum station 96 in sequence. In other variant embodiments, the workbench 2 can use eight or ten through holes 21 to perform multifunctional cleaning on the motor housing 100.

[0024] The six workstations mentioned above are all provided with a bearing mechanism 5 for bearing the motor housing 100. The bearing mechanism 5 includes a limit ring 51 and a bearing ring 52. The outer wall of the limit ring 51 abuts against the inner wall of the workbench 2 at the through hole 21. The limit ring 51 is constructed as a hollow cylindrical thin-walled part. The bottom of the limit ring 51 abuts against the bearing frame 1. The limit ring 51 partially extends out of the top of the workbench 2 and is fixedly connected to the bearing ring 52. The bearing ring 52 is movably connected to the workbench 2 in the vertical direction. The bearing ring 52 moves downward to control the bottom of the limit ring 51 to abut against the bearing frame 1.

[0025] A telescopic rod 53 that is telescopic in the vertical direction is fixedly provided on the outer peripheral side of the carrying ring 52. One end of the telescopic rod 53 is fixedly connected to the carrying ring 52, and the other end is fixedly connected to the workbench 2. A spring 54 is sleeved on the telescopic rod 53. One end of the spring 54 abuts against the bottom of the carrying ring 52, and the other end abuts against the top of the workbench 2. The outer wall of the limiting ring 51 always abuts against the inner wall of the carrying ring 52. A bracket 55 is fixedly provided on the inner wall of the limiting ring 51. The bracket 55 is constructed into a circular frame structure. A plurality of limiting members 56 are fixedly provided on the top of the bracket 55. The motor housing 100 is supported on the bracket 55. The limiting members 56 limit the outer peripheral side of the motor housing 100 to position the motor housing 100 to avoid interference between the motor housing 100 and the components of the present application.

[0026] like Figure 2As shown, the lifting mechanism 3 includes a lifting cylinder 31 and a protective cover 32. The cylinder body of the lifting cylinder 31 is fixedly connected to the top of the chamber 11 of the carrier 1. The piston rod of the lifting cylinder 31 moves in the vertical direction toward the limit ring 51. The protective cover 32 is fixed to the end of the piston rod. The protective cover 32 is formed into a thin-walled structure with a bottom opening. The upper cleaning component 4 is arranged in the protective cover 32. Specifically, the protective cover 32 is a cylinder, and the diameter of the protective cover 32 is approximately equal to the diameter of the bearing ring 52. After the protective cover 32 is lowered, it abuts against the bearing ring 52. The protective cover 32, the bearing ring 52, the limit ring 51 and the bottom end surface of the chamber 11 of the carrier 1 constitute a closed space. The closed space concentrates the cleaning airflow or medium to avoid diffusion, improve the cleaning efficiency, and reduce resource waste. The closed space prevents external foreign matter from entering, avoids interference with the motor housing 100 or other components, and is convenient for controlling internal air pressure, airflow and other parameters. A second conduit 63 communicating with the interior of the closed space is disposed at the bottom of the support frame 1. The second conduit 63 is connected to a water tank for collecting waste water and filtering and recycling the waste water.

[0027] like Figure 2 and Figure 3 As shown, in this embodiment, the lifting mechanism 3 corresponds to the carrying mechanism 5, but not one-to-one. Specifically, there are five lifting mechanisms 3, and the five lifting mechanisms 3 are distributed around the central axis of rotation of the workbench 2, but no lifting mechanism 3 is provided above the corresponding loading station 91 to avoid interference between the lifting mechanism 3 and the motor housing 100 during loading. The five lifting mechanisms 3 can correspond to the carrying mechanisms 5 on the other five stations, that is, the motor housing 100 needs to pass through the loading station 91, the rough washing station 92, the fine washing station 93, the blowing station 94, the drying station 95 and the vacuum station 96 in sequence, and except for the loading station 91, the lifting mechanism 3 of each station will clean the motor housing 100 located at the corresponding station.

[0028] Specifically, taking a motor casing 100 as an example, after the motor casing 100 is loaded onto the supporting mechanism 5 of the loading station 91, the workbench 2 rotates 60°, and the motor casing 100 moves to the rough washing station 92. After the rough washing is completed, it rotates 60° again, and the motor casing 100 moves to the fine washing station 93. And so on, the motor casing 100 is sent to the loading station 91 after completing the rough washing, fine washing, blowing, drying and vacuuming in sequence, and the cleaned motor casing 100 is removed.

[0029] like Figure 4As shown, the structures of the upper cleaning assembly 4 in the protective cover 32 above the three stations of rough washing, fine washing and blowing are approximately the same. Now take the upper cleaning assembly 4 above the rough washing station 92 as an example. The upper cleaning assembly 4 includes an upper cleaning motor 41, a spray suspension 42, and a first conduit 43. The shell of the upper cleaning motor 41 is fixedly connected to the protective cover 32, and the output shaft of the upper cleaning motor 41 extends toward the inside of the protective shell in the vertical direction. The output shaft of the upper cleaning motor 41 is connected to the spray suspension 42 in a transmission connection. Specifically, the upper cleaning motor 41 controls the rotation of the spray suspension 42 through a gear transmission, that is, the rotation center axis of the spray suspension 42 is not coaxial with the output shaft of the upper cleaning motor 41. The first conduit 43 is fixedly connected to the protective cover 32, and the first conduit is movably connected to the spray suspension 42 through a rotary joint. The upper cleaning motor 41 drives the spray suspension 42 to rotate relative to the first conduit.

[0030] The spray hanging member 42 is configured in an elongated strip shape, and a first spray rod 44 and a second spray rod 45 are fixedly provided on the side of the spray hanging member 42 facing the workbench 2, and the first spray rod 44 and the second spray rod 45 are both arranged vertically and in parallel. The first spray rod 44 is located at the bottom of the spray hanging member 42 near its rotation center, and preferably, the center axis of the first spray rod 44 is coaxial with the rotation center axis of the spray hanging member 42.

[0031] The second spray rod 45 is fixedly arranged at the bottom near the end of the spray suspension member 42, and the second spray rod 45, the spray suspension member 42 and the first spray rod 44 form a U-shaped spray structure. Preferably, there are two second spray rods 45, and the two second spray rods 45 are fixedly arranged at both ends of the spray suspension member 42 along the length direction of the spray suspension member 42, and the second spray rods 45 are symmetrically distributed with the first spray rod 44 as the central axis. The first spray rod 44 is used to extend into the motor housing 100 to clean the inner wall of the motor housing 100, and the second spray rod 45 is used to clean the outer wall of the motor housing 100. Specifically, the first spray rod 44 and the second spray rod 45 are both provided with a plurality of cleaning holes 46, and the cleaning holes 46 are interconnected, and the cleaning holes 46 are connected to the first conduit 43 through the first spray rod 44, the second spray rod 45, and the channels inside the spray suspension member 42. The first conduit 43 is connected to a water tank, and the water tank injects cleaning water into the cleaning hole 46 to clean the motor housing 100. Preferably, the cleaning holes 46 are evenly distributed along the vertical direction, and the cleaning holes 46 on the two spray rods are all arranged toward the first spray rod 44.

[0032] The spray hanger 42 is fixed with a plurality of first cleaning tubes 47 and a plurality of second cleaning tubes 48, both of which are hollow tubular structures, and the first cleaning tubes 47 and the second cleaning tubes 48 are connected inside the spray hanger 42. The first cleaning tubes 47 and the second cleaning tubes 48 both extend in a direction away from the spray hanger 42, and the first cleaning tubes 47 and the second cleaning tubes 48 are staggered in the vertical direction, that is, the output end of the first cleaning tube 47 and the output end of the second cleaning tube 48 are at different heights.

[0033] In this embodiment, the first cleaning tube 47 and the second cleaning tube 48 are both extended in the vertical direction, that is, the output end of the first cleaning tube 47 and the output end of the second cleaning tube 48 are perpendicular to the top end surface of the motor housing 100. In other embodiments, the first cleaning tube 47 and the second cleaning tube 48 are arranged at an angle with the vertical direction, that is, the first cleaning tube 47 and the second cleaning tube 48 are arranged at an angle, and the medium sprayed from the first cleaning tube 47 and the medium sprayed from the second cleaning tube 48 can clean the end surface outside the motor housing 100 at an inclined angle. During the cleaning process, the spraying angle is adjusted, and the medium can be more evenly distributed on the entire surface, avoiding the cleaning dead corner caused by the uneven end surface of the motor housing 100, ensuring that every corner of the end surface of the motor housing 100 can be cleaned, and improving the cleaning quality.

[0034] Preferably, a plurality of first cleaning tubes 47 are distributed in a circular array with the central axis of rotation of the spray suspension 42 as the central axis, and a plurality of second cleaning tubes 48 are distributed in a circular array with the central axis of rotation of the spray suspension 42 as the central axis, that is, a plurality of first cleaning tubes 47 and a plurality of second cleaning tubes 48 are distributed concentrically. Specifically, the second cleaning tube 48 is located at the periphery of the first cleaning tube 47. The vertical downward extension length of the second cleaning tube 48 is greater than the extension length of the first cleaning tube 47, that is, the output end of the second cleaning tube 48 is closer to the motor housing 100 than the output end of the second cleaning tube 48. Preferably, the end surface of the first cleaning tube 47 facing the motor housing 100 is located on the same horizontal plane, and the end surface of the second cleaning tube 48 facing the motor housing 100 is located on another horizontal plane.

[0035] like Figure 5 As shown, correspondingly, the three stations of rough washing, fine washing and blowing are all provided with a lower cleaning assembly 6 for cleaning the inner end surface of the motor housing 100 from below. The lower cleaning assembly 6 includes a lower cleaning motor and a lower cleaning plate 62, and the carrier frame 1 is concave to form a groove for accommodating the lower cleaning plate 62, and the lower cleaning plate 62 is rotatably connected in the groove.

The second conduit 63 is connected to the interior of the lower cleaning plate 62, and the central axis of the second conduit 63 is coaxial with the rotational central axis of the lower cleaning plate 62. The lower cleaning plate 62 is constructed as a horizontal plate-like structure, and the top end surface of the lower cleaning plate 62 is provided with a plurality of holes 64 connected to the second conduit 63 for cleaning the interior of the motor housing 100.

[0037] In this embodiment, the water tank passes water cleaning agent into the upper cleaning component 4 and the lower cleaning component 6 located in the rough cleaning station 92 to remove oil and particulate matter.

[0038] When the protective cover 32 at the drying station 95 forms a closed space with the corresponding carrying ring 52 and the limiting ring 51, hot air is introduced into the closed space to heat the motor housing 100 to dry out the moisture in the gap, thereby ensuring that the motor housing 100 is fully dry, reducing the risk of rust or corrosion on the metal parts of the motor housing 100, and providing better surface conditions for subsequent painting, coating or assembly.

[0039] After the protective cover 32 at the vacuum station 96 forms a closed space with the corresponding supporting ring 52 and limiting ring 51 in the vertical direction, the protective cover 32 is connected to the outside with a vacuum pump for vacuuming the closed space to further remove tiny particles and pollutants to ensure that the motor housing 100 is highly clean.
