Description

Technical Field

[0001] This invention relates to the field of motor stator processing technology, specifically a processing apparatus and method for a permanent magnet motor stator assembly. Background Technology

[0002] Compared with traditional motors, permanent magnet motors have the advantages of compact structure, high efficiency, high power density, fast response speed and energy saving and environmental protection. Therefore, permanent magnet motors are widely used in industrial automation, home appliances and aerospace fields. The performance of permanent magnet motors depends not only on the overall design of the motor, but also on the machining accuracy and assembly quality of its core components, the stator and rotor. Existing motor stator assembly processing equipment still has some shortcomings.

[0003] The invention patent with publication number CN116961333B discloses a motor stator processing device and method, including three rings arranged vertically. U-shaped blocks are fixedly connected to the corresponding sides of two adjacent rings. Swing plates are hinged to the inner cavities of two U-shaped blocks on the same side, and adjacent swing plates are hinged to each other. Four arc-shaped grooves are formed on the top of each ring. Through the cooperation of the rings, limiting plates, limiting rods, and swing plates, the distance between the rings can be adjusted when the device is not in operation. The swing plates drive the rings to move up and down, the M-shaped rods control the distance between the rings, and simultaneously move the limiting rods. The limiting rods provide auxiliary limiting for the motor stator and facilitate the disassembly of the limiting rods and other components. Although the above-mentioned device can achieve the auxiliary limiting function, it cannot adaptively adjust the support position of the device on the silicon steel sheet according to the winding position to avoid interference. Moreover, it cannot shake off the paint after the winding and impregnation are completed, and it cannot use small-amplitude vibration to help the paint adhere to the edge area of ​​adjacent silicon steel sheets, thus affecting the integrity of the stator.

[0004] Chinese patent application CN119787739A discloses a fixture, assembly system, and method for installing silicon steel sheets for motor stators. The system includes a limiting component adapted to contact the inner wall of the groove in the silicon steel sheet, restricting arbitrary movement of the silicon steel sheet. This solves the problem that misalignment of silicon steel sheets during installation can affect motor efficiency. While the aforementioned device can align the silicon steel sheets, it cannot axially compress them during use, nor can it ensure the stator remains intact while the edges of the silicon steel sheets are impregnated with paint. Summary of the Invention

[0005] The purpose of this invention is to provide a processing apparatus and method for a permanent magnet motor stator assembly, in order to solve the problems that existing stator assembly processing devices cannot adaptively adjust the support position of the device for the silicon steel sheet according to the winding position to avoid interference, and cannot shake off the paint after the winding and impregnation are completed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a processing device for a permanent magnet motor stator assembly, comprising a support base, on which a first motor, a support plate, and a collecting assembly are mounted. The support plate is provided with a first through hole, a first opening, a second through hole, a third through hole, and a second opening in a counter-clockwise direction.

[0009] As a further aspect of the present invention: the position of the first conveyor belt corresponds to the position of the second opening, and the position of the second conveyor belt corresponds to the position of the first through hole.

[0010] As a further embodiment of the present invention: the collecting component includes a second motor fixedly installed on the support base, a connecting plate fixedly connected to the output shaft of the second motor, a first mounting cylinder and a second mounting cylinder respectively installed on both sides of the bottom of the connecting plate, a fourth through hole opened at the bottom of the paint impregnation cylinder, and a fifth through hole opened at the bottom of the cleaning cylinder.

[0011] As a further embodiment of the present invention: the cleaning assembly includes a ball cover rotatably installed inside the cleaning cylinder, a connecting pipe fixedly connected to the ball cover, a first connecting ring fixedly connected to the outside of the connecting pipe, an mounting plate provided on the outside of the first connecting ring, spray holes opened on the ball cover, the first connecting ring is made of rubber, and the first connecting rings are evenly distributed on the mounting plate.

[0012] As a further embodiment of the present invention: the amplitude adjustment component includes a second electric push rod mounted on a connecting plate, a sliding sleeve connected to the second electric push rod, an installation shaft slidably mounted inside the sliding sleeve, a rotating plate fixedly connected to the installation shaft, a top block fixedly connected to the rotating plate, a protruding strip provided above the rotating plate, and the top block having a spherical structure and being rotatably mounted inside the rotating plate.

[0013] As a further embodiment of the present invention: the driving assembly includes a third motor installed in the connecting plate, a rotating wheel fixedly connected to the output shaft of the third motor, a rotating cylinder provided on the outer side of the rotating wheel, a second connecting ring fixedly connected to the connecting plate, the rotating cylinder and the second connecting ring being rotatably connected, a key rod connected to the middle key of the rotating cylinder, a top plate fixedly provided on the top of the key rod, the bottom of the key rod being connected to the outer shell, a protrusion fixedly connected to the top plate, the height of the bottom of the protrusion decreasing from the side closer to the center of the top plate to the side farther from the center of the top plate, a first spring fixedly provided between the outer shell and the rotating cylinder, and the rotating plate and the rotating wheel being rotatably connected.

[0014] As a further embodiment of the present invention: a baffle is installed on the slider, a corrugated tube is installed between the baffle and the outer shell, the corrugated tube is sleeved on the outside of the slider, and pressure blocks are installed on the baffles located on the uppermost and lowermost layers of the outer shell. A first oblique surface is provided on the opposite side of the upper and lower pressure blocks. The slider with the pressure blocks installed corresponds to the position of the first connecting rod. The diameter of the first connecting rod is smaller than the diameter of the second connecting rod.

[0015] As a further embodiment of the present invention: the ratchet assembly includes a second oblique surface and a third oblique surface formed on the slider, a spring hinge is mounted on the slider, a stop is mounted on the spring hinge, and the surface of the stop is flush with the second oblique surface.

[0016] A method for processing a permanent magnet motor stator assembly includes the following steps:

[0017] S1: Place the stator assembly to be processed into the first through hole. The first motor drives the turntable, the first electric push rod and the connecting plate to rotate. After rotating the housing to the position aligned with the first through hole, adjust the position of the stator assembly by the second conveyor belt. Then shorten the first electric push rod to move the housing to the inside of the stator assembly. Support the stator assembly by the support assembly.

[0018] S2: When supporting the stator assembly, the connecting frame is driven to rotate clockwise by the fourth motor. The first connecting rod and the second connecting rod abut against the slider, causing the slider to slide inside the housing. The second spring is stretched, supporting the stator assembly from the inside out. After the support is completed, the housing and the stator assembly are moved to the first opening for winding.

[0019] S3: The stator assembly after winding is impregnated with varnish through the impregnation tube in the second through hole. After impregnation, the varnish dripping from the stator assembly is recovered through the cleaning tube in the third through hole. The stator assembly is vibrated slightly by the amplitude adjustment component and the drive component. The varnish forms a local bond to the edge area of ​​the adjacent silicon steel sheets, enhancing its integrity.

[0020] S4: The second opening and the first conveyor belt discharge the stator assembly after it has been dipped in paint. The fourth motor drives the connecting frame to rotate counterclockwise, causing the slider to retract into the housing, thereby detaching the dipped stator assembly from the housing. After the discharge is completed, the housing is rotated back to the position of the third through hole, and the paint on the housing is cleaned by the cleaning component.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By using a support assembly and a pawl assembly, the device achieves the function of adjusting the support position. When the device is winding, the first connecting rod can be driven to rotate counterclockwise by the fourth motor, so that the first or second connecting rod abuts against the stop block. The stop block rotates clockwise on the slider through the spring hinge, so that the first and second connecting rods act on the slider at different positions. When the fourth motor drives the connecting frame to rotate, the connecting frame will abut against the second oblique surface, causing the slider to slide outward inside the housing, changing the support position of the device to adapt to different winding positions of the stator assembly. This device achieves the functions of supporting and adjusting the support position through a single drive structure, solving the problem that existing stator assembly processing devices cannot adaptively adjust the support position of the device for silicon steel sheets according to the winding position.

[0023] 2. By setting up amplitude adjustment and drive components, the function of shaking off excess paint after winding and impregnation is realized. After the device is wound and impregnated, the third motor drives the rotating wheel to rotate, which in turn drives the rotating drum to rotate. During the rotation of the drum, the top block can intermittently support the convex strip, thereby causing the top plate and key rod to intermittently raise and lower the outer shell. During the intermittent raising and lowering of the outer shell, the stator assembly supported on the outside of the outer shell will vibrate, thereby shaking off excess paint on the stator assembly. After the winding is completed, the weight of the stator assembly increases, which increases the downward tension on the spring on the outside of the key rod, thereby causing the convex strip to vibrate. With the top block firmly pressed against the wall, the device can change the initial position of the sliding sleeve by extending or shortening the second electric push rod, thereby adjusting the rotation angle of the rotating plate and thus changing the distance between the top block and the central axis of the top plate. The closer the distance between the top block and the central axis of the top plate, the smaller the amplitude generated when the outer shell rotates, and vice versa. When the device shakes off excess paint from the stator assembly, it reduces the amplitude, and the paint forms a local bond to the edge area of ​​the adjacent silicon steel sheets, enhancing their integrity and promoting uniform distribution of the paint, while avoiding the formation of paint nodules. After removing the stator assembly, when cleaning the paint on the outer shell, the amplitude can be increased to improve the cleaning effect.

[0024] 3. When supporting the stator from the inside out, this device utilizes a second connecting rod with a diameter smaller than the first connecting rod. This allows the device to first apply the second connecting rod to the slider in the corresponding area, and then apply the first connecting rod to the slider in that area. This allows the device to first tighten the middle part of the stator assembly. Then, the pressure blocks on the upper and lower rows of sliders act on the upper and lower sides of the stator assembly, axially pressing the stator assembly. This achieves the function of supporting first and then pressing, ensuring that the silicon steel sheets do not loosen during edge impregnation. This solves the problem that existing stator assembly processing devices cannot ensure that the stator as a whole does not loosen while impregnating the edges of the silicon steel sheets. The device is equipped with a bellows, and the support assembly, in conjunction with the bellows, allows the device to adapt to paint environments, ensuring that the gap between the slider and the outer shell remains sealed, thus improving the durability of the device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0039] Example 1: As Figures 1-11 As shown, this embodiment proposes a processing device for a permanent magnet motor stator assembly, including a support base 1. A first motor 2, a support plate 6, and a collecting assembly 16 are mounted on the support base 1. The support plate 6 has a first through hole 7, a first opening 8, a second through hole 9, a third through hole 10, and a second opening 11 arranged sequentially in a counterclockwise direction. A turntable 3 is fixedly connected to the output shaft of the first motor 2. A first electric push rod 4 is mounted on the turntable 3. A connecting plate 5 is connected to the top of the first electric push rod 4. A cleaning cylinder 14 is installed in the third through hole 10. A cleaning assembly 17 is mounted on the cleaning cylinder 14. A paint impregnation cylinder 15 is installed in the second through hole 9. An amplitude adjustment assembly 18 and a drive assembly 19 are mounted on the connecting plate 5. A housing 20 is provided below the drive assembly 19. A support assembly 21 is installed on the outer casing 20, and a pawl assembly 22 is installed on the support assembly 21. The support plate 6 is used to support the entire device. The first through hole 7 on the support plate 6 is used to place the stator assembly to be processed. The second conveyor belt 13 is used to adjust the initial position of the stator assembly. The first opening 8 is used to wind the stator assembly. The second through hole 9 is used to impregnate the wound stator assembly with paint. The third through hole 10 is used to slightly shake the impregnated stator, thereby using the paint to form a local bond on the edge area of ​​the adjacent silicon steel sheets, enhancing its integrity and ensuring the integrity of the stator. The second opening 11 and the first conveyor belt 12 are used to discharge the impregnated stator. After the discharge is completed, the outer casing 20 is rotated to the position of the third through hole 10 to clean the outer casing 20.

[0040] The support assembly 21 includes a fourth motor 2101 installed inside the housing 20. A connecting frame 2102 is fixedly connected to the output shaft of the fourth motor 2101. A slider 2105 is slidably installed inside the housing 20. A second spring 2106 is installed between the slider 2105 and the housing 20. Second connecting rods 2104 are provided around the inside of the housing 20. First connecting rods 2103 are installed on the upper and lower sides of the second connecting rods 2104. The top of the uppermost first connecting rod 2103 is connected to the connecting frame 2102. The fourth motor 2101 is used to drive the connecting frame 2102 to rotate. When the connecting frame 2102 rotates, it will drive the first connecting rod 2103 and the second connecting rod 2104 to abut against the slider 2105, so that the slider 2105 moves from the inside to the outside. The second spring 2106 facilitates the subsequent reset of the slider 2105, thereby realizing the function of supporting the stator assembly from the inside to the outside. After the support is completed, the first motor 2 can drive the turntable 3 to rotate, which will drive the first electric push rod 4 and the connecting plate 5 to rotate. When the connecting plate 5 rotates, it will switch the position of the stator assembly to realize the functions of winding, impregnation, removal of excess paint from the stator assembly, stator assembly discharge, and cleaning of paint on the surface of the outer shell 20.

[0041] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details:

[0042] like Figure 1 As shown, in a preferred embodiment, based on the above method, the turntable 3 and the support plate 6 are rotatably connected, and a first conveyor belt 12 and a second conveyor belt 13 are installed below the support plate 6. The first conveyor belt 12 and the second conveyor belt 13 are used to transport the stator assembly so as to transport the stator assembly to the corresponding position for winding and impregnation.

[0043] like Figure 1 As shown, in a preferred embodiment, based on the above method, the position of the first conveyor belt 12 corresponds to the position of the second opening 11, and the position of the second conveyor belt 13 corresponds to the position of the first through hole 7. The first conveyor belt 12 is used to transport the winding and impregnated stator assembly, and the second conveyor belt 13 is used to precisely adjust the initial position of the stator assembly.

[0044] like Figure 3 , Figure 7 and Figure 11As shown, in a preferred embodiment, based on the above method, the collection component 16 further includes a second motor 1601 fixedly installed on the support base 1. A connecting plate 1602 is fixedly connected to the output shaft of the second motor 1601. A first mounting cylinder 1603 and a second mounting cylinder 1604 are respectively installed on both sides of the bottom of the connecting plate 1602. A fourth through hole 1605 is opened at the bottom of the paint dipping cylinder 15, and a fifth through hole 1606 is opened at the bottom of the cleaning cylinder 14. The second motor 1601 is used to drive the connecting plate 1602 to rotate. When the connecting plate 1602 rotates, it can change the position of the first mounting cylinder 1603 and the second mounting cylinder 1604 so as to collect the paint dripping after dipping.

[0045] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the cleaning assembly 17 further includes a ball cover 1701 rotatably installed inside the cleaning cylinder 14. A connecting pipe 1702 is fixedly connected to the ball cover 1701, and a first connecting ring 1703 is fixedly connected to the outside of the connecting pipe 1702. A mounting plate 1704 is provided on the outside of the first connecting ring 1703. A spray hole 1705 is opened on the ball cover 1701. The first connecting ring 1703 is made of rubber and is evenly distributed on the mounting plate 1704. The device can be connected to a water pipe on the connecting pipe 1702, and then the mounting plate 1704 can be pulled to drive the ball cover 1701 to rotate inside the cleaning cylinder 14, thereby changing the cleaning angle of the device. When the ball cover 1701 rotates, the first connecting ring 1703 will be squeezed and deformed.

[0046] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the amplitude adjustment component 18 further includes a second electric push rod 1801 mounted on the connecting plate 5. A sliding sleeve 1802 is connected to the second electric push rod 1801. A mounting shaft 1803 is slidably mounted inside the sliding sleeve 1802. A rotating plate 1804 is fixedly connected to the mounting shaft 1803. A top block 1805 is fixedly connected to the rotating plate 1804. A protrusion 1806 is provided above the rotating plate 1804. The top block 1805 has a spherical structure. The top block 1805 is rotatably mounted inside the rotating plate 1804. The rotatably mounted top block 1805 can rotate within the rotating plate 1804, allowing the top block 1805 to rotate when passing the protrusion 1806, reducing the wear of the top block 1805. It will also intermittently push the protrusion 1806, thereby generating vibration. By extending or shortening the second electric push rod 1801, the position of the sliding sleeve 1802 is adjusted, which in turn pushes the mounting shaft 1803. While the mounting shaft 1803 rotates, it will slide within the sliding sleeve 1802 to allow for subsequent amplitude adjustment.

[0047] like Figure 5As shown, in a preferred embodiment, based on the above method, the drive assembly 19 further includes a third motor 1901 installed in the connecting plate 5. A rotating wheel 1902 is fixedly connected to the output shaft of the third motor 1901. A rotating cylinder 1903 is provided on the outer side of the rotating wheel 1902. A second connecting ring 1904 is fixedly connected to the connecting plate 5. The rotating cylinder 1903 and the second connecting ring 1904 are rotatably connected. A key rod 1905 is connected to the middle key of the rotating cylinder 1903. A top plate 1906 is fixedly provided on the top of the key rod 1905. The bottom of the key rod 1905 is connected to the outer casing 20. The outer casing 20 can be intermittently raised on the rotating cylinder 1903 by the key rod 1905 and the first spring 1907. The second connecting ring 1904 lowers the drum 1903 to rotate stably. The convex strip 1806 is fixedly connected to the top plate 1906. The height of the bottom of the convex strip 1806 decreases from the side closer to the center of the top plate 1906 to the side farther away from the center of the top plate 1906. The first spring 1907 is fixedly installed between the outer shell 20 and the drum 1903. The rotating plate 1804 is rotatably connected to the rotating wheel 1902 to ensure that the position of the top block 1805 on the convex strip 1806 changes when the rotating plate 1804 rotates. After adjusting the position of the top block 1805, the intermittent lifting height of the convex strip 1806 can be changed, thereby adjusting the amplitude of the device. The closer the top block 1805 is to the central axis of the top plate 1906, the smaller the amplitude, and vice versa.

[0048] like Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, a baffle 2107 is further installed on the slider 2105, and a corrugated tube 23 is installed between the baffle 2107 and the outer shell 20. The corrugated tube 23 is sleeved on the outside of the slider 2105, ensuring that paint does not enter between the slider 2105 and the outer shell 20, thus ensuring that the slider 2105 remains closed when moving. Pressure blocks 2108 are installed on both the uppermost and lowermost baffles 2107 of the outer shell 20, and a first oblique surface 2 is provided on the opposite side of both the upper and lower pressure blocks 2108. 109. The two sets of first oblique surfaces 2109 opposite each other ensure that the device can axially press the upper and lower sides of the stator assembly. The slider 2105 with the pressure block 2108 is positioned in a position corresponding to the first connecting rod 2103. The diameter of the first connecting rod 2103 is smaller than the diameter of the second connecting rod 2104. The smaller diameter of the first connecting rod 2103 allows the device to first use the second connecting rod 2104 to support the middle part of the slider 2105, and then act on the two sets of sliders 2105 on the upper and lower sides, realizing the function of supporting from the inside out first, and then axially pressing the stator assembly from the upper and lower sides.

[0049] like Figures 8-11As shown, in a preferred embodiment, based on the above method, the ratchet assembly 22 further includes a second oblique surface 2201 and a third oblique surface 2202 formed on the slider 2105. A spring hinge 2203 is mounted on the slider 2105, and a stop 2204 is mounted on the spring hinge 2203. The surface of the stop 2204 is flush with the second oblique surface 2201. Figure 10 As can be seen, when switching the support position, the device rotates the first connecting rod 2103 counterclockwise, so that the first connecting rod 2103 abuts against the third oblique surface 2202, and then against the right-angle surface of the stop block 2204, until the first connecting rod 2103 passes the stop block 2204. After the stop block 2204 rotates clockwise, it is reset by the spring hinge 2203. Then the first connecting rod 2103 rotates clockwise again, so that the first connecting rod 2103 abuts against the second oblique surface 2201 and the oblique surface of the stop block 2204, thereby realizing the function of switching the support position.

[0050] Example 3: The solutions in Examples 1 and 2 will be further described below with reference to their specific working methods. See the description below for details:

[0051] Specifically, the processing equipment and method for this permanent magnet motor stator assembly, when used, include: Figure 1 , Figure 3 and Figures 7-11 As shown, the stator assembly to be processed is placed in the first through hole 7. The first motor 2 drives the turntable 3, the first electric push rod 4, and the connecting plate 5 to rotate. After the outer shell 20 is rotated to a position aligned with the first through hole 7, the position of the stator assembly is adjusted by the second conveyor belt 13. Then, the first electric push rod 4 is shortened to move the outer shell 20 to the inside of the stator assembly. The stator assembly is supported from the inside out by the support assembly 21. The fourth motor 2101 drives the connecting frame 2102 to rotate clockwise. The first connecting rod 2103 and the second connecting rod 2104 abut against the second oblique surface 2201 of the slider 2105 and the oblique surface of the stop block 2204, so that the slider 2105... Sliding within the outer casing 20, the second spring 2106 is stretched, supporting the stator assembly from the inside out. During the support process, since the diameter of the first connecting rod 2103 is smaller than that of the second connecting rod 2104, the second connecting rod 2104 first supports the slider 2105 in the middle of the outer casing 20, and then the smaller diameter first connecting rod 2103 acts on the two sets of sliders 2105 on the upper and lower sides. The pressure blocks 2108 on the upper and lower baffles 2107 of the outer casing 20 move towards each other, and the first oblique surface 2109 gradually presses the upper and lower sides of the stator assembly, realizing the function of supporting from the inside out first, and then pressing the stator assembly axially from the upper and lower sides towards the middle. After the support and pressing steps are completed, the first motor 2 drives the turntable 3 to rotate, driving the first electric push rod 4, the connecting plate 5 and the outer casing 20 to rotate as a whole, moving the outer casing 20 and the stator assembly to the first opening 8 for winding.

[0052] like Figures 1-7 and Figure 11 As shown, the stator assembly after winding is impregnated with varnish through the impregnation tube 15 in the second through hole 9. After impregnation, the varnish dripping from the stator assembly is recovered through the cleaning tube 14 in the third through hole 10. The stator assembly is vibrated slightly by the amplitude adjustment component 18 and the drive component 19 to make the varnish adhere to the edge area of ​​adjacent silicon steel sheets. Figure 5 and Figure 6 As shown, the device can adjust the position of the sliding sleeve 1802 by extending or shortening the second electric push rod 1801, thereby pushing the mounting shaft 1803. While the mounting shaft 1803 rotates, it slides inside the sliding sleeve 1802, causing the rotating plate 1804 to rotate around the rotating wheel 1902. The position of the top block 1805 changes with the position of the convex strip 1806. Since the height of the bottom of the convex strip 1806 decreases from the side closer to the center of the top plate 1906 to the side farther away from the center of the top plate 1906, the intermittent lifting height of the convex strip 1806 can be changed after adjusting the position of the top block 1805, thereby adjusting the amplitude of the device. The closer the top block 1805 is to the central axis of the top plate 1906, the smaller the amplitude, and vice versa. The third motor 1901 drives the rotating wheel 1902 to rotate, which in turn drives the rotating drum 1903 to rotate outside the second connecting ring 1904. When the drum 1903 rotates, it causes the key rod 1905, top plate 1906, convex strip 1806, and outer casing 20 to rotate as a whole, using centrifugal force to clean excess paint from the outer casing 20. The top block 1805 rotates itself as it passes the rotating convex strip 1806, thus reducing wear on the top block 1805. The top block 1805 also intermittently pushes the convex strip 1806, causing the key rod 1905, top plate 1906, and outer casing 20 to rise and fall intermittently, causing the outer casing 20 to vibrate and shake off the paint from the stator assembly and the outer casing 20. This small-amplitude vibration of the stator assembly allows the paint to adhere to the gaps between adjacent silicon steel sheets on the stator assembly, enhancing the overall integrity of the stator. The second opening 11 and the first conveyor belt 12 discharge the dipped stator assembly. The fourth motor 2101 drives the connecting frame 2102 to rotate counterclockwise, causing the slider 2105 to retract into the outer shell 20, thereby detaching the dipped stator assembly from the outer shell 20. After discharge, the outer shell 20 is rotated back to the position of the third through hole 10, and the paint on the outer shell 20 is cleaned by the cleaning component 17. Before cleaning, the second motor 1601 drives the connecting plate 1602 to rotate. When the connecting plate 1602 rotates, it can change the position of the first mounting cylinder 1603 and the second mounting cylinder 1604. The first mounting cylinder 1603 collects the dripping paint after dipping. During cleaning, a water pipe is connected to the connecting pipe 1702, and the mounting plate 1704 is pulled, causing the ball cover 1701 to rotate inside the cleaning cylinder 14. When the ball cover 1701 rotates, the first connecting ring 1703 is squeezed and deformed, thereby changing the cleaning angle of the device.
