Description

Technical Field

[0001] The invention relates to the technical field of reactor varnish dipping, and in particular to automatic vacuum varnish dipping equipment for a reactor. Background Art

[0002] Reactor varnishing is a process of immersing the coil and core of the reactor in a special insulating varnish to form an insulating coating. This step plays an important role in the production process of the reactor. At present, the reactor varnishing process mainly relies on vacuum varnishing equipment.

[0003] For example, the authorization announcement number CN113451044B discloses a vacuum varnishing process for the production of reactors, and discloses vacuum varnishing equipment for reactors, including a varnishing container, in which a certain amount of insulating varnish is loaded, and then the reactor is placed in a hanging cage, and then the hanging cage is used to carry the reactor into the varnishing container through a matching hanging device, and then the container cover is closed, and the inside of the container is evacuated through a vacuum pump to complete the vacuum varnishing operation. After the varnishing is completed, the container is opened, and then the reactor is lifted out through the hanging device and transferred to the matching paint baking equipment, and then the paint is baked dry.

[0004] The shortcomings of the existing reactor vacuum dipping equipment are that after the paint dipping is completed, the existing reactor vacuum dipping equipment needs to rely on manual labor to transfer the painted reactor out of the container, and then send it to the paint baking equipment to dry the paint. This process is cumbersome and inconvenient, which affects the work efficiency. In addition, when transferring the reactor, it is necessary to open the container, which will cause the paint volatiles or harmful gases in the container to directly diffuse into the surrounding environment and cause harm. Although there are related prior arts that disclose a complete set of automatic paint dipping and paint baking equipment, the existing technical solution still needs to rely on transmission equipment to transfer the painted reactor to the paint baking station after the reactor is painted, and then rely on the paint baking assembly for drying. After drying, it is transported to the discharge end.

[0019] Beneficial effects of the present invention:

[0020] 1. The box cover of the present invention drives the reactor to descend through the bottom support plate and enter the paint dipping box for paint dipping. When the box cover descends and docks with the paint dipping box, the blocks distributed on the box cover are fixedly docked with the iron rods in the card slots on the closed lifting cover by means of magnetic suction parts. In this way, when the box cover drives the reactor to rise through the bottom support plate, the closed lifting cover will rise synchronously therewith, and the closed lifting cover, the bottom support plate and the box cover form a paint baking space. When the closed lifting cover is raised, the power connection component enables the electric baking mechanism distributed in the closed lifting cover to be energized and operated, which is convenient for directly baking the paint on the reactor raised after the paint dipping, and there is no need to transfer the reactor after the paint dipping separately for the paint baking operation, which makes the overall operation convenient and improves the overall paint dipping processing efficiency.

[0021] 2. When the box cover of the present invention drives the closed lifting cover to rise, the closed lifting cover cooperates with the box cover and the paint dipping box to form an independent paint baking space, so as to prevent harmful substances emitted by the paint from being directly released into the surrounding environment and causing harm. At the same time, during the paint baking process, the vacuum pump runs to extract the volatile substances. When the paint baking reaches the set time, the closed lifting cover is lowered and reset, and the inductor can be removed. When the box cover is in the raised state, the bottom support plate connected to the box cover by the suspension rod cooperates with the square frame to abut against the top port of the paint dipping box, effectively closing the port of the paint dipping box, preventing the volatile substances of the paint remaining in the paint dipping box from being released, and improving the safety of the working environment.

[0022] 3. After the closed lifting cover of the present invention relies on the electric baking mechanism to carry out the paint baking operation on the reactor for a set time, the timer will feedback a signal to the PLC controller, so that the PLC controller triggers the corresponding stepper motor to run. The stepper motor relies on the push rod to connect the convex handle of the iron rod, so that the convex handle drives the iron rod to slide back and reset, thereby achieving unlocking, making it convenient for the closed lifting cover to automatically fall and open, and for workers to take away the processed reactor.

[0023] 4. The reactor of the present invention is lowered into the paint dipping box for varnish dipping, and then raised to automatically bake the paint, without the need for long travel transfer and multi-step processing. The overall structure is compact, the volume is small, and the operation is fast and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-Figure 8As shown, an automatic vacuum paint dipping device for a reactor comprises a paint dipping box 1 and a closed box cover 2, the box cover 2 is cooperatively arranged above the paint dipping box 1, one side of the paint dipping box 1 is fixedly connected with a hydraulic telescopic rod 3 through a mounting seat, and the telescopic end of the hydraulic telescopic rod 3 is fixedly connected with the box cover 2, when it is necessary to close the box cover 2 on the top of the paint dipping box 1, the hydraulic telescopic rod 3 is controlled to retract, so that the box cover 2 is docked at the top of the paint dipping box 1; a paint injection assembly is arranged on the other side of the paint dipping box 1, and the paint injection assembly is used to inject insulating paint into the paint dipping box 1; a vacuum pump 5 is fixedly installed on the box cover 2, the air suction end of the vacuum pump 5 cooperates with the internal space of the paint dipping box 1, and the air outlet end is connected with a conveying pipe 6 for external processing equipment, when the box cover 2 is closed and docked to the top of the paint dipping box 1, the vacuum pump 5 is started to evacuate the inside of the paint dipping box 1 to a vacuum state, and then paint is injected for paint dipping;

[0036] The device also includes a reactor bearing mechanism and a closed lifting cover 34; the reactor bearing mechanism is arranged below the box cover 2, and the reactor bearing mechanism is matched with the inside of the paint dipping box 1, the closed lifting cover 34 is slidably sleeved on the outside of the paint dipping box 1, the closed lifting cover 34 is a box structure with openings at the top and bottom, and an electric baking mechanism is distributed on the inner wall of the closed lifting cover 34, and the top size of the closed lifting cover 34 matches the size of the box cover 2, and a magnetic locking mechanism is also provided between the closed lifting cover 34 and the box cover 2. When the box cover 2 is lowered and docked on the paint dipping box 1, the closed lifting cover 34 and the box cover 2 are fixedly docked through the magnetic locking mechanism. In this way, when the box cover 2 is raised, the closed lifting cover 34 can be driven to rise synchronously, and finally the closed lifting cover 34 encloses the space between the box cover 2 and the paint dipping box 1 to prevent the harmful gas volatilized by the paint after dipping from directly volatilizing into the surrounding environment when the box cover 2 is opened to cause harm;

[0037] The closed lifting cover 34 is provided with a timed reset unlocking mechanism cooperating with the magnetic locking mechanism;

[0038] The closed lifting cover 34 is also provided with a power connection component electrically connected to the electric baking mechanism. When the closed lifting cover 34 is raised synchronously with the box cover 2, the power connection component enables the electric baking mechanism to be energized and operated, so as to facilitate the drying of the reactor that has been immersed in paint, without the need to transfer the reactor after the paint is immersed to related equipment, and after a certain period of electric baking, the timed reset unlocking mechanism is started to unlock the magnetic locking mechanism, so that the closed lifting cover 34 can fall by gravity, so as to facilitate the removal of the baked reactor.

[0039] In some specific implementation schemes, since the paint-impregnated reactor is electrically baked in a closed environment to dry the paint, the closed lifting cover 34 will fall down, making it convenient for workers to take away the reactor. However, since the box cover 2 is separated from the paint impregnation box 1, the volatile paint substances or harmful gases in the paint impregnation box 1 are easily diffused to the outside. In order to avoid this situation, the reactor bearing mechanism is required to block the top of the paint impregnation box 1 when the box cover 2 is raised, and after the box cover 2 is lowered, it can ensure that the paint contacts the reactor. Therefore, the specific setting is: Figures 2 to 4 As shown, the reactor bearing mechanism includes a suspension rod 9, a bottom support plate 16 and an elastic stopper. A plurality of suspension rods 9 are provided and fixedly distributed at various corner positions at the bottom of the box cover 2. The bottom support plate 16 is fitted inside the paint dipping box 1. There is a gap between the edge of the bottom support plate 16 and the inner wall of the paint dipping box 1. The bottom support plate 16 is fixedly connected to the suspension rod 9. The bottom support plate 16 is used to place the reactor. The elastic stopper is slidably connected to the bottom end of the suspension rod 9, and the elastic stopper is fitted between the edge of the bottom support plate 16 and the inner wall of the paint dipping box 1. A limit stopper 23 matching the elastic stopper is fixedly connected to the inner wall of the paint dipping box 1 near the top. When the box cover is closed, When the bottom support plate 16 is lifted to the top port of the paint dipping box 1 by the bottom support plate 16, the elastic stopper is limited and blocked by the limit stopper 23, so that it fits together with the edge of the bottom support plate 16. In this way, the elastic stopper and the bottom support plate 16 as a whole block the top of the paint dipping box 1, and the elastic stopper generates a rebound force during this process. When the box cover 2 is lowered, the bottom support plate 16 is driven to lower through the suspension rod 9. At this time, the elastic stopper is separated from the limit stopper 23, and then resets and separates from the bottom support plate 16 by relying on the rebound force, so that a gap is generated between the bottom support plate 16 and the inner wall of the paint dipping box 1, so that the paint can easily cover the reactor on the bottom support plate 16.

[0040] Among them, the elastic stopper includes a square frame 15 and a connecting spring 22. The outer edge of the square frame 15 is in contact with the inner wall of the paint immersion box 1, and the inner edge of the inner ring is matched with the bottom support plate 16. The position of the square frame 15 is higher than the bottom support plate 16. The bottom end of the suspension rod 9 passes through the square frame 15, and the square frame 15 can slide relative to the suspension rod 9. There are multiple connecting springs 22, each of which is connected between the corresponding suspension rod 9 and the square frame 15, and the connecting spring 22 can be stretched. When the connecting spring 22 is in an initial state, the square frame 15 and the bottom support plate 16 are in a separated state. When the box cover 2 is lifted with the bottom support plate 16 and the square frame 15 through the suspension rod 9, the square frame 15 is first blocked by the limit baffle 23 and stops. At this time, the box cover 2 continues to drive the bottom support plate 16 to rise through the suspension rod 9, so that the bottom support plate 16 contacts the bottom of the square frame 15, and the two are spliced, thereby closing the top of the paint immersion box 1.

[0041] In some specific embodiments, in order to ensure that after the box cover 2 is lowered to contact the closed lifting cover 34, the magnetic locking mechanism automatically locks the box cover 2 and the closed lifting cover 34, such as Figure 5 and Figure 6 As shown, the magnetic locking mechanism includes a card slot 24 and a card block 8. There are two card slots 24, which are respectively opened on the front and rear sides of the top edge of the closed lifting cover 34. The inner walls of both sides of the card slot 24 are provided with cylindrical grooves 25, and an iron rod 26 is inserted into the cylindrical groove 25 for horizontal sliding. There are two card blocks 8, which are respectively fixedly connected to the two sides of the box cover 2, and the card blocks 8 are aligned with the card slots 24. A magnetic attraction piece that cooperates with the iron rod 26 is provided on the card block 8, and the iron rod 26 cooperates with the timing reset unlocking mechanism.

[0042] Among them, the magnetic attraction part includes a magnet block 28 and a locking groove 27. The magnet block 28 is embedded and fixedly connected to the center position inside the card block 8. There are two locking grooves 27, which are through-opened on both sides of the card block 8. The locking groove 27 cooperates with the iron rod 26, and the space where the magnet block 28 is located is connected to the position where the locking groove 27 is located.

[0043] When the box cover 2 is lowered and docked to the top of the paint dipping box 1, the block 8 is inserted into the corresponding inner side of the slot 24. At this time, the locking slots 27 on both sides of the block 8 are aligned with the iron rod 26. Then the iron rod 26 slides into the locking slot 27 under the magnetic attraction of the magnet block 28, so that the block 8 is fixedly docked with the slot 24. In this way, when the box cover 2 is raised, the box cover 2 can drive the closed lifting cover 34 to rise.

[0044] In some specific embodiments, in order to ensure that after the closed lifting cover 34 is lifted, the electric baking mechanism distributed on its inner wall starts to be powered on and operated, the power connection assembly includes a power socket 14, a power plug 13 and a fixed bracket 12, the fixed bracket 12 is fixedly connected to one side of the paint dipping box 1, the power plug 13 is fixedly installed on the top of the fixed bracket 12, and the power plug 13 is externally connected to an external power supply, the power socket 14 is embedded and installed on one side of the top of the closed lifting cover 34, and the power socket 14 is aligned with the power plug 13, the electric baking mechanism is electrically connected to the power socket 14, and a pressure sensing switch electrically connected to the vacuum pump 5 is also provided on the top of the fixed bracket 12, and the pressure sensing switch is aligned with the edge of the closed lifting cover 34.

[0045] When the box cover 2 drives the closed lifting cover 34 to rise, the power socket 14 on the closed lifting cover 34 is just connected to the power plug 13, so that the electric baking mechanism is powered on and operated, which is convenient for drying the reactor after internal paint dipping. At the same time, the pressure sensor on the top of the fixed bracket 12 is squeezed, so that the vacuum pump 5 is operated, and the vacuum pump 5 is convenient for extracting the water vapor or volatile substances evaporated during the paint drying process.

[0046] In some specific implementation schemes, in order to ensure that the reactor after being dipped in paint is heated in the space formed by the closed lifting cover 34, the box cover 2 and the bottom support plate 16 for a set time, the timing reset unlocking mechanism starts the reset iron rod 26, so that the closed lifting cover 34 automatically falls, such as Figures 6 to 8As shown, the timing reset unlocking mechanism includes a PLC controller 4, a timer 35, an installation cavity 29 and a stepper motor 30. The PLC controller 4 is installed on the box cover 2, and the timer 35 is installed on the closed lifting cover 34. The timer 35 is electrically connected to the power socket 14, and the timer 35 is also electrically connected to the PLC controller 4. The installation cavity 29 is opened in the side wall of the closed lifting cover 34. There are multiple installation cavities 29, and they are distributed corresponding to the cylindrical grooves 25. A strip-shaped opening 33 is opened on the side of the cylindrical groove 25 close to the corresponding installation cavity 29. The end of the iron rod 26 away from the slot 24 is fixedly connected with a convex handle 31, and the end of the convex handle 31 away from the iron rod 26 passes through the strip-shaped opening 33 and is in the installation cavity 29. The convex handle 31 is slidably matched with the strip-shaped opening 33. The stepper motor 30 is fixedly installed in the installation cavity 29, and the stepper motor 30 is electrically connected to the PLC controller 4. The spindle end of the stepper motor 30 is fixedly connected with a push rod 32 matched with the corresponding convex handle 31.

[0047] The push rod 32 is originally located at a side close to the strip opening 33. At this time, the push rod 32 is aligned with the lug 31, and before the iron rod 26 slides out of the cylindrical groove 25, the lug 31 is away from the push rod 32. When the iron rod 26 slides out of the cylindrical groove 25 under the action of magnetic attraction and is inserted into the locking groove 27, the iron rod 26 just slides with the lug 31 to fit the corresponding push rod 32. When the closed lifting cover 34 rises with the box cover 2, the power socket 14 on the closed lifting cover 34 is connected to the power plug 13. At this time, not only the electric grilling mechanism is powered on, but also the electric grilling mechanism is powered on. The timer 35 is powered on synchronously and starts timing. When the timer 35 reaches the set time, the PLC controller 4 receives the signal of the timer 35 and then sends a command to the stepper motor 30 to make the stepper motor 30 run. The stepper motor 30 drives the push rod 32 to rotate in the corresponding direction, so that the push rod 32 pushes the convex handle 31, so that the convex handle 31 slides along the strip-shaped opening 33, thereby driving the corresponding iron rod 26 to slide back and reset, that is, the iron rod 26 is separated from the lock groove 27 on the block 8, so that unlocking is achieved.

[0048] In some specific embodiments, in order to prevent the closed lifting cover 34 from falling directly and causing damage when it falls, Figure 1 and Figure 2 It can be seen that the two sides of the paint dipping box 1 are fixedly connected with the piston cylinder 18, the piston block 21 is slidably arranged in the piston cylinder 18, the piston block 21 is fixedly connected with the connecting guide rod 19, and the upper end of the connecting guide rod 19 is fixedly connected to the closed lifting cover 34, and the bottom of the piston cylinder 18 is provided with a small leakage hole 20.

[0049] When the closed lifting cover 34 rises, it drives the piston block 21 to slide and rise along the piston cylinder 18 through the connecting guide rod 19. During this process, the piston cylinder 18 inhales a certain amount of air through the air leakage hole 20. When the closed lifting cover 34 is unlocked and falls by gravity, the piston block 21 presses the piston cylinder 18 to slide down. During this process, the piston block 21 is subjected to friction resistance and at the same time, the air in the piston cylinder 18 is pressed out and reacted by the air pressure. In this way, a slow descent is achieved to prevent the closed lifting cover 34 from falling down quickly.

[0050] In some specific embodiments, the electric baking mechanism includes an embedding groove, an electric baking lamp 17 and a thermostat 7. There are multiple embedding grooves distributed on the inner wall of the closed lifting cover 34. There are multiple groups of electric baking lamps 17, which are respectively installed in the embedding grooves. The electric baking lamps 17 are electrically connected to the power socket 14. The thermostat 7 is installed on the closed lifting cover 34, and the thermostat 7 is electrically connected to the electric baking lamps 17. The electric baking lamps 17 here can also be replaced with other electric heating elements. The electric baking lamps 17 heat the space enclosed by the raised closed lifting cover 34, and the thermostat 7 monitors the temperature of the space where the reactor is located and controls the temperature to remain at a certain value.

[0051] In some specific embodiments, the paint injection assembly includes a paint bucket 11 and a delivery pump 10. The paint bucket 11 is arranged on one side of the paint dipping box 1, and the delivery pump 10 is installed at the bottom of the paint bucket 11. The feed end of the delivery pump 10 is connected to the inside of the paint bucket 11, and the discharge end is connected to the bottom of the paint dipping box 1. When paint dipping is required, the delivery pump 10 is started to pump the paint in the paint bucket 11 into the paint dipping box 1, and a valve control switch can be installed at the discharge end of the delivery pump 10.

[0052] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0053] First, place the reactor on the bottom support plate 16, then start the hydraulic telescopic rod 3 to retract, so that the box cover 2 drives the bottom support plate 16 to descend into the paint dipping box 1 through the suspension rod 9. When the box cover 2 is sealed and docked with the top of the paint dipping box 1, start the delivery pump 10 to allow the delivery pump 10 to deliver the insulating paint material in the paint bucket 11 to the paint dipping box 1. At this time, a gap is generated between the bottom support plate 16 and the inner wall of the paint dipping box 1, so that the paint can easily cover the reactor on the bottom support plate 16. At the same time, start the vacuum pump 5 to extract the vacuum state inside the paint dipping box 1 to facilitate paint dipping.

[0054] When the paint dipping is completed, the hydraulic telescopic rod 3 is controlled to drive the box cover 2 to rise. As the box cover 2 is lowered and docked to the top of the paint dipping box 1, the block 8 on the box cover 2 is inserted into the inner side of the corresponding slot 24. At this time, the locking slots 27 on both sides of the block 8 are aligned with the iron rod 26. Then, the iron rod 26 slides into the locking slot 27 under the magnetic attraction of the magnet block 28, so that the block 8 is fixedly docked with the slot 24. In this way, when the box cover 2 is raised, the box cover 2 can drive the closed lifting cover 34 to rise.

[0055] And when the box cover 2 drives the bottom support plate 16 to rise, the bottom support plate 16 and the square frame 15 are in a separated state, which can ensure that a gap is maintained between the bottom support plate 16 and the inner wall of the paint dipping box 1 to prevent the paint from being pushed up by the bottom support plate 16, and when the bottom support plate 16 and the square frame 15 are raised to the top port of the paint dipping box 1, the square frame 15 is first blocked by the limit baffle 23 and stops. At this time, the box cover 2 continues to drive the bottom support plate 16 to rise through the suspension rod 9, so that the bottom support plate 16 contacts the bottom of the square frame 15, and the two are spliced ​​together. At the same time, because the outer edge of the square frame 15 contacts the inner wall of the paint dipping box 1, the top of the paint dipping box 1 is closed.

[0056] And when the box cover 2 is raised, the closed lifting cover 34 is raised synchronously, and the closed lifting cover 34 encloses the space between the box cover 2 and the paint dipping box 1, forming a relatively closed space, which prevents harmful gases or volatiles inside the paint dipping box 1 from directly evaporating into the surrounding environment when the box cover 2 is opened, and can also prevent the volatiles of the undried paint on the surface of the reactor from emitting to the external space.

[0057] At the same time, when the box cover 2 drives the closed lifting cover 34 to rise, the power socket 14 on the closed lifting cover 34 is just connected to the power plug 13, so that the electric baking mechanism is powered on and operated, which is convenient for drying the reactor after internal paint dipping. At the same time, the pressure sensor on the top of the fixed bracket 12 is squeezed, so that the vacuum pump 5 is operated. The vacuum pump 5 is convenient for extracting the evaporated water vapor or volatile substances in the process of paint drying, and there is no need to transfer the reactor dipped in paint to the external space and then send it into the paint baking equipment.

[0058] When the power socket 14 is connected to the power plug 13, not only the electric grilling mechanism is powered on, but also the timer 35 is powered on and starts timing. When the timer 35 reaches the set time, the PLC controller 4 receives the signal from the timer 35 and then sends a command to the stepper motor 30 to make the stepper motor 30 run.

[0059] Since the push rod 32 is originally located at a side close to the strip opening 33 and is aligned with the lug 31, and before the iron rod 26 slides out of the cylindrical groove 25, the lug 31 is away from the push rod 32, when the iron rod 26 slides out of the cylindrical groove 25 under the action of magnetic attraction and is inserted into the locking groove 27, the iron rod 26 just slides with the lug 31 to fit the corresponding push rod 32, so that when the stepping motor 30 drives the push rod 32 to rotate in the corresponding direction, the push rod 32 pushes the lug 31, so that the lug 31 slides along the strip opening 33, thereby driving the corresponding iron rod 26 to slide back and reset, that is, the iron rod 26 is separated from the locking groove 27 on the block 8, so that unlocking is achieved;

[0060] Then the closed lifting cover 34 falls by gravity, exposing the painted reactor and allowing workers to take it away directly. At this time, the bottom support plate 16 and the square frame 15 combine to block the top of the paint dipping box 1 to prevent the paint volatiles inside the paint dipping box 1 from evaporating to the external space.

[0061] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
