[0037] Compared with the prior art, the present invention has at least the following beneficial effects:

[0038] 1. This invention provides an automatic painting system for the inner cavity of a transformer finned radiator, which requires no manual intervention and has a high degree of automation. Multiple transformer finned radiators are placed side by side on a shelf. A painting cart travels close to the shelf, and a moving chassis drives a paint tank and a lifting frame along the shelf. The paint tank contains paint. After the lifting frame reaches a transformer finned radiator, two automatic docking devices, one above the other, move and dock with the two docking ports of the transformer finned radiator. The two docking devices work in two ways: one automatically docking device delivers paint from the paint tank into the transformer finned radiator, while the other automatically docking device returns the paint to the paint tank, thus completing the painting of the inner cavity of the transformer finned radiator.

[0039] 2. The present invention provides an automatic paint filling system for the inner cavity of a transformer plate radiator. After the paint filling is completed, during the separation process between the paint filling pipeline and the filling port, the paint filling pipeline gradually moves away from the filling port clamping plate. To prevent residual paint dripping from the paint filling pipeline, the actuating component operates, thereby driving the rotating disk seat to rotate on the damping shaft. At this time, the opening of the upper liquid collecting hood increases while the height of the upper liquid collecting hood decreases, thereby collecting as much paint as possible from the paint filling pipeline. After the paint filling pipeline stops moving, the actuating component operates, thereby driving the rotating disk seat to rotate in the opposite direction on the damping shaft. At this time, the opening of the upper liquid collecting hood decreases while the height of the upper liquid collecting hood increases. The upper liquid collecting hood is located directly below the paint filling pipeline and is clamped below the flange. At this time, the upper liquid collecting hood swings left and right multiple times to fling out as much residual paint as possible from the paint filling pipeline. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example 1:

[0057] Please refer to the following: Figures 1 to 3 This embodiment provides an automatic paint filling system for the inner cavity of a transformer plate radiator, comprising:

[0058] Shelf 10 is used to support multiple sets of transformer plate radiators;

[0059] The accompanying paint filling cart 11 is located on one side of the shelf 10. The accompanying paint filling cart 11 includes a mobile chassis 12, a paint tank 13 and a lifting frame 14. The paint tank 13 and the lifting frame 14 are installed on the mobile chassis 12.

[0060] The two automatic filling port docking devices 15 are arranged one above the other and slidably connected to the lifting frame 14. The two automatic filling port docking devices 15 are respectively connected to the paint tank 13 through a pump pipeline to form a paint filling circuit that communicates with the inner cavity of the transformer plate radiator.

[0061] The working principle and beneficial effects of the above technical solution are as follows:

[0062] This invention discloses an automatic painting system for the inner cavity of a transformer finned radiator. Multiple transformer finned radiators are arranged side-by-side on a shelf 10. A painting cart 11 travels close to the shelf 10. Specifically, a movable chassis 12 drives a paint tank 13 and a lifting frame 14 along the shelf. The paint tank 13 contains paint. Each time the lifting frame 14 reaches a transformer finned radiator, two automatic inlet docking devices 15, positioned one above the other, move and dock with the two inlets of the transformer finned radiator. One of the automatic inlet docking devices 15 delivers paint from the paint tank 13 into the transformer finned radiator, while the other automatic inlet docking device 15 returns the paint to the paint tank 13, thus completing the painting of the inner cavity of the transformer finned radiator. This automatic painting system for the inner cavity of a transformer finned radiator provided by this invention requires no manual intervention and has a high degree of automation.

[0063] In this embodiment, the mobile chassis 12 adopts a steel frame, the linear motion wheel set 16 is installed at the bottom of the mobile chassis 12, the downward channel is set on one side of the shelf 10, the downward track is laid in the downward channel, the mobile chassis 12 travels on the downward track through the linear motion wheel set 16, and is positioned sequentially at the painting station of each transformer plate heat sink. The mobile chassis 12 is equipped with a sensor for detecting the position of the transformer plate heat sink.

[0064] The working principle and beneficial effects of the above technical solution are as follows:

[0065] The descending trough is buried underground to reduce the use of ground space. The linear motion wheel set 16 works to drive the mobile chassis 12 to move along the descending track. The mobile chassis 12 is equipped with sensors for detecting the position of the transformer plate heat sink, so that the lifting frame 14 can accurately stop at the location of each transformer plate heat sink.

[0066] In this embodiment, a side lifting rail 17 is installed on the lifting frame 14, a side lifting seat 18 is slidably connected to the side lifting rail 17, an automatic docking device 15 for filling is installed on the side lifting seat 18, a lifting rack 19 is installed on one side of the side lifting rail 17, a lifting motor 20 is installed on the side lifting seat 18, and a rotating gear 21 that meshes with the lifting rack 19 is installed at the output end of the lifting motor 20.

[0067] The working principle and beneficial effects of the above technical solution are as follows:

[0068] The lifting motor 20 installed on the side lifting seat 18 works, thereby driving the rotating gear 21 installed on the output end of the lifting motor 20 to rotate. With the cooperation of the rotating gear 21 and the lifting rack 19, the automatic filling port docking device 15 installed on the side lifting seat 18 moves up and down along the side lifting track 17 to complete the docking of the two filling ports of the transformer plate radiator.

[0069] Example 2:

[0070] Please refer to the following: Figures 4 to 7 Based on the above embodiment 1, the automatic filling port docking device 15 includes:

[0071] A transverse platform 22 is mounted on a side lifting seat 18, and a side transverse track 23 is mounted on the transverse platform 22.

[0072] Side transverse sliding seat 24 is slidably connected to side transverse sliding track 23;

[0073] The propulsion cylinder 25 is mounted on the side lifting seat 18, and the output end of the propulsion cylinder 25 is connected to the side transverse moving seat 24.

[0074] Paint filling line 26 is connected to the side transverse sliding seat 24 via mounting block 27. Paint filling line 26 is used to connect to the flange face of the filling port. Paint filling line 26 is connected to the pump line 1.

[0075] The clamping assembly 28 is installed on the transverse platform 22. The paint filling pipeline 26 and the clamping assembly 28 press the flange face of the filling port together.

[0076] The working principle and beneficial effects of the above technical solution are as follows:

[0077] After the side lifting seat 18 is raised to the preset position, the clamping plate tightening assembly 28 is engaged on the filling port. Then, the propulsion cylinder 25 installed on the side lifting seat 18 operates, thereby driving the side transverse moving seat 24 and the paint filling pipe 26 installed on the side transverse moving seat 24 via the mounting block 27 to slide along the side transverse moving track 23. After the paint filling pipe 26 is connected to the flange surface of the filling port, the clamping plate tightening assembly 28 operates. The paint filling pipe 26 and the clamping plate tightening assembly 28 exert force against each other, so that the paint filling pipe 26 can be tightly connected to the filling port. Then, with the pump pipeline operating, either the paint in the paint tank 13 is sent into the transformer finned radiator, or the paint is returned to the paint tank 13.

[0078] In this embodiment, the card plate tightening assembly 28 includes:

[0079] A fixing plate 29 is installed on the end of the transverse platform 22 away from the propulsion cylinder 25. A central opening is provided on the fixing plate 29 to facilitate the protrusion of the paint filling pipe 26.

[0080] The filling port clamping plate 30 is parallel to the fixing plate 29. The filling port clamping plate 30 has a flared mouth 31 that is easy to be clamped onto the flange surface of the filling port. Four guide rods 32 are arranged in an array on the filling port clamping plate 30. A guide sleeve 33 is installed on the fixing plate 29 and sleeved on the guide rods 32.

[0081] Tightening cylinder 34 is mounted on fixed plate 29, and the output end of tightening cylinder 34 is connected to filling port clamping plate 30.

[0082] The working principle and beneficial effects of the above technical solution are as follows:

[0083] After the side lifting seat 18 is raised to the preset position, it drives the filling port clamping plate 30 and the flared mouth 31 located on the filling port clamping plate 30 to engage with the filling port. The push cylinder 25 works, thereby driving the side transverse moving seat 24 and the paint filling pipe 26 installed on the side transverse moving seat 24 via the mounting block 27 to slide along the side transverse moving track 23, and after protruding from the central opening through the fixing plate 29, it connects with the flange surface of the filling port. Then the tightening cylinder 34 works, thereby driving the filling port clamping plate 30 and the guide rod 32 installed on the filling port clamping plate 30 to slide along the guide sleeve 33. In this way, the filling port clamping plate 30 and the paint filling pipe 26 can exert force on each other, so that the paint filling pipe 26 can be tightly connected to the filling port.

[0084] Example 3:

[0085] Please refer to the following: Figure 4 Based on the above embodiment 1, two sets of positioning brackets 35 are set on the lifting frame 14, one above the other, to correspond to the two automatic docking devices 15 of the filling port respectively. Five position switches 36 are distributed on the positioning brackets 35 from top to bottom. The automatic docking device 15 of the filling port is equipped with a detection switch plate 37 adapted to the position switches 36.

[0086] The working principle and beneficial effects of the above technical solution are as follows:

[0087] Five position switches 36 are distributed from top to bottom on the positioning bracket 35, thereby realizing the adjustment and positioning of the lifting position of the automatic docking device 15.

[0088] Example 4:

[0089] Please refer to the following: Figures 8 to 13 Based on Embodiment 2 above, in this embodiment, a liquid collection assembly 38 is installed at the bottom end of the fixing plate 29. The liquid collection assembly 38 is used to collect the paint falling from the paint filling pipe 26. The liquid collection assembly 38 includes:

[0090] The upper liquid collection hood 39 is made of elastic material. The telescopic ring is installed at the opening end of the upper liquid collection hood 39. The opening end of the upper liquid collection hood 39 is set upward. The upper liquid collection hood 39 is connected to the paint tank 13 through the pump pipeline 43.

[0091] Rotating disc base 40 is located below the upper liquid collection hood 39. The actuating component is installed between the upper liquid collection hood 39 and the rotating disc base 40 to adjust the size and height of the hood opening of the upper liquid collection hood 39.

[0092] The damping shaft 41 and the rotating disk seat 40 are rotatably mounted on the damping shaft 41. The two shaft ends of the damping shaft 41 are mounted on the bottom end of the fixing plate 29 through the side mounting bracket 42.

[0093] The working principle and beneficial effects of the above technical solution are as follows:

[0094] After the painting process is completed, during the separation of the painting pipeline 26 from the filling port, the painting pipeline 26 gradually moves away from the filling port clamping plate 30. To prevent residual paint in the painting pipeline 26 from dripping, the actuating component operates, thereby driving the rotating disk seat 40 to rotate on the damping shaft 41. At this time, the opening of the upper liquid collecting hood 39 increases while the height of the upper liquid collecting hood 39 decreases, thus collecting as much paint as possible from the painting pipeline 26. After the painting pipeline 26 stops moving, the actuating component operates, thereby driving the rotating disk seat 40 to rotate in the opposite direction on the damping shaft 41. At this time, the opening of the upper liquid collecting hood 39 decreases while the height of the upper liquid collecting hood 39 increases. The upper liquid collecting hood 39 is located directly below the painting pipeline 26 and is clamped below the flange. At this time, the upper liquid collecting hood 39 swings left and right multiple times to fling out as much residual paint as possible from the painting pipeline 26.

[0095] It should be noted that the telescopic ring at the opening end of the upper liquid collection hood 39 is designed with a square structure. Each side of the telescopic ring can elastically extend and retract, and the initial state of the telescopic ring is an extended state to adapt to the state where the opening of the upper liquid collection hood 39 becomes larger. When the opening of the upper liquid collection hood 39 becomes smaller, the telescopic ring retracts accordingly.

[0096] In this embodiment, the action component includes:

[0097] Upper oscillating block 44 is installed at the bottom of the upper liquid collection hood 39;

[0098] The lower fixed block 45 and the upper oscillating block 44 slide at the top of the lower fixed block 45 away from the upper liquid collection hood 39;

[0099] The fixing frame 46 has one end connected to the bottom end of the lower fixing block 45, and the other end of the fixing frame 46 extends into the rotating disk seat 40 and is connected to the damping shaft 41.

[0100] A gathering ring 47 is sleeved outside the upper liquid collection cover 39, and limit sliding rods 48 are distributed oppositely on the gathering ring 47.

[0101] The lifting rod 49 has one end sleeved on the limiting slide rod 48, and the other end of the lifting rod 49 passes through the lower fixing block 45 and is equipped with a side slider. The arc-shaped lifting groove 50 is opened on the rotating disk seat 40, and the side slider is slidably connected in the arc-shaped lifting groove 50.

[0102] The working principle and beneficial effects of the above technical solution are as follows:

[0103] The actuation component operates, causing the rotating disk seat 40 to rotate on the damping shaft 41. With the cooperation of the arc-shaped lifting groove 50 and the side slider, the lifting rod 49 is lifted on the lower fixed block 45, which in turn causes the gathering ring 47 mounted on the lifting rod 49 to lift. During the lifting process of the gathering ring 47, as... Figure 11 As shown, the opening of the upper liquid collecting hood 39 becomes smaller, and the height of the upper liquid collecting hood 39 increases.

[0104] It should be noted that the rotating disk base 40 has a cavity to facilitate the insertion of the fixing frame 46 and the installation of the damping shaft 41. When the rotating disk base 40 rotates, it has a side opening that prevents it from interfering with the movement of the fixing frame 46.

[0105] In this embodiment, the action component further includes:

[0106] Guide groove 51 is arc-shaped and opened on the rotating disk seat 40; guide slider 52 is slidably connected in the guide groove 51.

[0107] The rotating rod 53 has an external gear 54 installed at one end. An external rack 55 adapted to the external gear 54 is installed on the guide slider 52. The other end of the rotating rod 53 is fitted with a lower fixing block 45 and an eccentric rotating block 56 is installed thereon. The upper oscillating block 44 has a transmission groove adapted to the eccentric rotating block 56 at the end away from the upper liquid collection cover 39.

[0108] The working principle and beneficial effects of the above technical solution are as follows:

[0109] As the opening of the upper liquid collecting hood 39 decreases and its height increases, the telescopic ring at the opening of the upper liquid collecting hood 39 is engaged below the flange. At this time, the external gear 54 meshes with the external rack 55. The actuation components switch operation, thereby driving the guide slider 52 to slide within the guide groove 51. The external rack 55, mounted on the guide slider 52, drives the rotating rod 53 to rotate through its engagement with the external gear 54. The rotating rod 53 drives the eccentric block 56 to rotate within the transmission groove. With the engagement of the eccentric block 56 and the transmission groove, the upper oscillating block 44 is driven to swing left and right repeatedly on the lower fixed block 45. During the left and right swinging of the upper liquid collecting hood 39 mounted on the upper oscillating block 44, the telescopic ring causes the flange and the paint filling pipe 26 connected to the flange to swing slightly, so as to fling out as much residual paint as possible from the paint filling pipe 26.

[0110] In this embodiment, the action component further includes:

[0111] An inclined rotating shaft 57 is provided, with a drive motor 58 installed at one end and the other end of the inclined rotating shaft 57 extending into the rotating disk seat 40 and equipped with a helical gear 59. A helical gear 60 adapted to the helical gear 59 is installed on the damping shaft 41.

[0112] Friction turntable 61 is mounted on inclined rotating shaft 57, and guide slider 52 is provided with friction surface adapted to friction turntable 61;

[0113] The electric telescopic rod 62 is mounted on the side mounting bracket 42 via a connecting bracket. The drive motor 58 is mounted on the electric telescopic rod 62 and is used to switch the transmission connection between helical gear 1 59 and helical gear 2 60, as well as between friction turntable 61 and guide slider 52.

[0114] The working principle and beneficial effects of the above technical solution are as follows:

[0115] The drive motor 58 operates, thereby driving the inclined shaft 57 installed at its output end, the friction disk 61 installed on the inclined shaft 57, and the first helical gear 59 to rotate synchronously. Meanwhile, the electric telescopic rod 62 operates, realizing the switching of the transmission connection between the first helical gear 59 and the second helical gear 60, as well as between the friction disk 61 and the guide slider 52.

[0116] When it is necessary for the rotating disk seat 40 to rotate on the damping shaft 41, the electric telescopic rod 62 extends, and the first helical gear 59 meshes with the second helical gear 60. At this time, the inclined rotating shaft 57 drives the damping shaft 41 and the rotating disk seat 40 connected to the damping shaft 41 to rotate, thereby realizing the adjustment of the size and height of the cover end of the upper liquid collection cover 39.

[0117] When it is necessary for the guide slider 52 to slide within the guide groove 51, the electric telescopic rod 62 retracts, the helical gear 1 59 and the helical gear 2 60 disengage, and the friction turntable 61 contacts the friction surface on the guide slider 52. At this time, the inclined rotating shaft 57 drives the friction turntable 61 to rotate, thereby realizing the sliding of the guide slider 52 within the guide groove 51. The external rack 55 installed on the guide slider 52, through its cooperation with the external gear 54, drives the rotating rod 53 to rotate. The rotating rod 53 drives the eccentric rotating block 56 to rotate within the transmission groove. With the cooperation of the eccentric rotating block 56 and the transmission groove, the upper oscillating block 44 is driven to swing left and right multiple times on the lower fixed block 45. During the left and right swinging process of the upper liquid collection cover 39 installed on the upper oscillating block 44, the expansion ring drives the flange and the paint filling pipe 26 connected to the flange to swing slightly, so as to throw out the paint remaining in the paint filling pipe 26 as much as possible.
