Description

Technical Field

[0001] The invention relates to the technical field of wound capacitor production equipment, and in particular to a wound capacitor vacuum automatic stirring and heating impregnation device. Background Art

[0002] In the existing production process of wound capacitors, winding, impregnation, formation, packaging and other steps are required in sequence. Each type of wound capacitor has different production processes and raw materials due to its different operating conditions and performance. Taking the impregnation of wound capacitors as an example, different impregnation materials require the use of relatively thick impregnation liquids to impregnate the capacitor core of the wound capacitor within a specific temperature range during the impregnation process of some wound capacitors. If ordinary impregnation methods are used, the relatively thick impregnation liquid will penetrate into the capacitor core very slowly, or even fail to penetrate into the capacitor core. Therefore, the impregnation environment is often vacuumed to extract the air inside the capacitor core. After the capacitor core is immersed in the impregnation liquid, the vacuum environment is released, so that the impregnation liquid on the surface of the capacitor core is pressed into the capacitor core under the action of atmospheric pressure, thereby increasing the impregnation speed and preventing the generation of bubbles in the capacitor core after impregnation.

[0003] In the existing vacuum impregnation process, the impregnation liquid needs to be heated first, and the heating environment needs to be evacuated before heating the impregnation liquid. After heating to a predetermined temperature, the cover is opened and the impregnation liquid is stirred using an external tool. After stirring evenly, the capacitor core row is placed in the impregnation device and evacuated again for impregnation. In this production method, because the concentration of the thick impregnation liquid is uneven after heating, it needs to be stirred evenly before impregnation. Multiple vacuuming is required during the working process, which is time-consuming, energy-consuming, and has low production efficiency.

DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below, and preferred embodiments of the present invention are provided. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] Example:

[0031] See also Figure 1-Figure 5 The present embodiment provides a wound capacitor vacuum automatic stirring and heating impregnation device, including a main body 1, a cover 2 and a first driving assembly 3. The main body 1 is provided with a vacuum chamber 11, the upper part of the vacuum chamber 11 is open, the cover 2 can be slidably covered on the main body 1 through the first driving assembly 3, and an exhaust pipe 12 is arranged on the main body 1, and the exhaust pipe 12 is connected to the vacuum chamber 11. The main body 1 also includes a liquid holding tray 4, a bearing platform 5, a lifting mechanism 6, a heating assembly 7 and a stirring mechanism 8 arranged in the vacuum chamber 11. The liquid holding tray 4 is placed on the bearing platform 5; the lifting mechanism 6 is used to drive the bearing platform 5 to move up and down in the vertical direction and position; the heating assembly 7 is arranged on the bearing platform 5; the stirring mechanism 8 includes a separately arranged stirring rod 81 and a stirring driving assembly 82, the stirring rod 81 is movably arranged in the liquid holding tray 4, the stirring driving assembly 82 is arranged on the main body 1 below the liquid holding tray 4, and the stirring driving assembly 82 drives the stirring rod 81 to move in the liquid holding tray 4 through magnetic interaction.

[0032] Specifically, the heating component 7 is an electric heating plate, a groove is arranged on the carrier 5, the electric heating plate is embedded in the groove, the liquid holding tray 4 is arranged on the carrier 5 and located above the electric heating plate, and the impregnation liquid in the liquid holding tray 4 is heated by the electric heating plate. Of course, in some embodiments, the heating component 7 is not limited to the electric heating plate, but can also be other heating structures and methods, such as by laying a pipeline in the carrier 5 and passing a heat medium into the pipeline, the liquid holding tray 4 can also be heated. It should be noted that the heat medium can be hot water, hot oil, hot steam, etc.

[0033] It can be understood that when the workpiece to be impregnated needs to be impregnated, the impregnation liquid is loaded into the liquid receiving tray 4, and the liquid receiving tray 4 is placed on the supporting platform 5, the workpiece to be impregnated is placed in the vacuum chamber 11, the cover 2 is driven to move by the first driving member, and the cover 2 is closed, and the vacuum chamber 11 is connected to an external vacuum device through the exhaust pipe 12, and the vacuum chamber 11 is evacuated to a vacuum, the impregnation liquid in the liquid receiving tray 4 is heated by the heating component 7, and the impregnation liquid in the liquid receiving tray 4 is stirred by the stirring driving component 82. The impregnation liquid in the liquid receiving tray 4 is fully stirred, and the impregnation liquid at various places in the liquid receiving tray 4 is fully stirred. The liquid is heated more evenly, and the viscosity of the impregnation liquid at various locations of the liquid holding tray 4 is consistent after stirring. After the impregnation liquid is heated to the set temperature, the lifting mechanism 6 drives the support platform 5 and the liquid holding tray 4 to move upward to perform the impregnation operation on the impregnated part. During the entire working process, there is no need to open the cover 2 to stir the impregnation liquid in the liquid holding tray 4, so that during a single impregnation process, there is no need to evacuate the vacuum chamber 11 for the second time, that is, only the vacuum chamber 11 needs to be evacuated once to complete the entire impregnation process of the impregnated part, which not only greatly saves working time, but also saves the energy consumed by the second vacuuming. In addition, by arranging the stirring rod 81 and the stirring drive device separately, it is convenient to stir the impregnation liquid in the liquid holding tray 4 when the liquid holding tray 4 is close to the stirring drive device, and it is convenient to perform the impregnation operation on the impregnated part when the liquid holding tray 4 is far away from the stirring drive device, and the operation process will not cause interference.

[0034] Further, the stirring drive assembly 82 includes a rotation drive module 821 and a linear drive module 822, the linear drive module 822 is arranged on the main body 1, and is used to drive the rotation drive module 821 to move back and forth along the length direction of the liquid receiving tray 4, the rotation drive module 821 is arranged on the linear drive module 822, and is used to drive the stirring rod 81 to rotate horizontally, and the linear drive module 822 and the rotation drive module 821 are both arranged below the carrier 5. Of course, in some embodiments, the linear drive module 822 can also be arranged along the width direction of the liquid receiving tray 4 to drive the rotation drive module 821 and the stirring rod 81 to move back and forth along the width direction of the liquid receiving tray 4 for stirring.

[0035] It can be understood that the stirring rod 81 is driven to rotate horizontally in the liquid receiving tray 4 by the rotary drive module 821, and the rotary module is driven to move back and forth along the length direction of the liquid receiving tray 4 by the linear drive module 822, and the stirring rod 81 is driven to move back and forth along the length direction of the liquid receiving tray 4 to stir, forming a compound motion stirring, so that the impregnation liquid in the liquid receiving tray 4 is fully stirred. Of course, the linear drive module 822 is best to drive the rotary module and the stirring rod 81 to move and stir along the length direction of the liquid receiving tray 4, and reciprocating along the width direction of the liquid receiving tray 4 is second.

[0036] Furthermore, it also includes a control component 9, which is used to control the start and stop of the linear drive module 822. The control component 9 includes a first contact 91 and a second contact 92. When the first contact 91 and the second contact 92 are disconnected, the linear drive module 822 stops, and when the first contact 91 and the second contact 92 are connected, the linear drive module 822 works; the first contact 91 is connected to the carrier 5, and the second contact 92 is connected to the main body 1. The carrier 5 has an impregnation station located at the upper part and a heating and stirring station located at the lower part. When the carrier 5 rises to the impregnation station at the upper part, the first contact 91 is disconnected from the second contact 92, and when the carrier 5 descends to the heating and stirring station at the lower part, the first contact 91 is connected to the second contact 92.

[0037] It can be understood that the control component 9 is equivalent to the switch of the linear drive module 822. When the liquid receiving tray 4 moves downward and the first contact 91 and the second contact 92 are in contact and connected, it is equivalent to the switch of the linear module being turned on. At this time, the linear module can work normally, driving the rotation drive module 821 and the stirring plate to move back and forth along the length direction of the liquid receiving tray 4, so that the stirring rod 81 moves back and forth in the liquid receiving tray 4 along the length direction of the liquid receiving tray 4 to stir. Of course, in some embodiments, the rotation drive module 821 can also be controlled by the first contact and the second contact. When the first contact and the second contact are in contact and connected, the rotation drive mechanism drives the stirring rod 81 to stir the impregnation liquid in the liquid receiving tray 4. It should be noted that the liquid level of the impregnation liquid must be above the stirring rod 81, and the length of the stirring plate is less than the width of the liquid receiving tray 4, so that the stirring rod 81 can be rotated and stirred in the liquid receiving tray 4.

[0038] Furthermore, the rotation driving module 821 includes an electromagnet 8211 and a first motor 8212, the first motor 8212 is detachably connected to the linear driving module 822, the electromagnet 8211 is detachably connected to the output shaft of the first motor 8212, and the stirring rod 81 is made of a material that can be adsorbed by a magnet.

[0039] It can be understood that when the electromagnet 8211 is energized, the stirring rod 81 is limited by magnetic attraction, and when the first motor 8212 drives the electromagnet 8211 to rotate horizontally, the stirring rod 81 can be driven to rotate horizontally in the liquid receiving tray 4 for stirring.

[0040] Furthermore, the stirring rod 81 is in the shape of a cylindrical rod, and is made of a permanent magnetic material or a steel material.

[0041] It should be noted that when the linear drive module 822 drives the rotational drive module 821 and the stirring rod 81 to move back and forth along the length direction of the liquid receiving tray 4, the stirring rod 81 moves along the length direction of the liquid receiving tray 4. During the movement, the stirring rod 81 moves by rolling and moving, thereby reducing friction resistance and making the stirring smoother.

[0042] Furthermore, the linear drive module 822 includes a driving screw 8221, a screw nut 8222, a guide rod 8223, a slide 8224 and a second motor 8225. The driving screw 8221 is horizontally rotatably connected to the main body 1, the guide rod 8223 is fixedly connected to the main body 1, the driving screw 8221 and the guide rod 8223 are arranged parallel to each other, the screw nut 8222 is threadedly connected to the driving screw 8221, one side of the slide 8224 is detachably connected to the screw nut 8222, and the other side of the slide 8224 is slidably connected to the guide rod 8223, the first motor 8212 is detachably connected to the slide 8224, the second motor 8225 is installed on the main body 1, and the output shaft of the second motor 8225 is coaxially connected to the driving screw 8221.

[0043] It can be understood that the second motor 8225 drives the screw rod 8221 to rotate, driving the screw nut 8222 and the slide 8224 to reciprocate along the axial direction of the screw rod. The reciprocating movement is achieved by controlling the forward and reverse rotation of the motor. The guide rod 8223 plays a guiding role and prevents the slide 8224 from rotating. Therefore, the second motor 8225 drives the screw rod 8221 to rotate, driving the screw nut 8222, the slide 8224 and the first motor 8212 to reciprocate along the axial direction of the screw rod.

[0044] Furthermore, the first driving assembly 3 includes a slide rail 31, a slider 32 and a cylinder 33. The slide rail 31 is arranged on the upper part of the main body 1. The slider 32 is slidably connected to the slide rail 31. The slide rail 31 and the slider 32 are arranged in two groups. The two groups of slide rails 31 and the slider 32 are respectively arranged on both sides of the main body 1. The two ends of the cover 2 are respectively connected to the two sliders 32 at both ends. The fixed end of the cylinder 33 is connected to the main body 1, and the driving end of the cylinder 33 is connected to the cover 2.

[0045] It can be understood that the cylinder 33 is extended and retracted to drive the slider 32 to reciprocate along the slide rail 31, and the slide rail 31 is fixed on the main body 1, and the slider 32 is fixed on the cover 2, so that the cylinder 33 drives the slider 32 and the cover 2 to move relative to the main body 1 and the slide rail 31, so that the cover 2 is opened or closed. Two sets of sliders 32 and slide rails 31 are respectively arranged on both sides of the main body 1 to improve the stability of the cover 2 sliding on the main body 1.

[0046] Furthermore, a sealing strip 13 is arranged on a surface of the main body 1 opposite to the cover 2 , and the sealing strip 13 is arranged around the opening of the vacuum chamber 11 .

[0047] It can be understood that an annular groove is provided on the upper surface of the main body 1, and the sealing strip 13 is embedded in the annular groove and fixedly arranged, and the upper surface of the sealing strip 13 protrudes from the upper surface of the main body 1, so that when the cover 2 covers the main body 1, the lower surface of the cover 2 abuts against the upper surface of the sealing strip 13 to achieve a seal between the main body 1 and the cover 2, preventing air from entering from the gap between the main body 1 and the cover 2 when the vacuum chamber 11 is evacuated, resulting in failure to meet the vacuum requirements.

[0048] Furthermore, a visual window 21 is arranged on the cover 2, and two visual windows 21 are arranged, and the two visual windows 21 are arranged toward the inside of the vacuum chamber 11 from different angles. It can be understood that the situation in the vacuum chamber 11 can be conveniently observed through the visual window 21. By arranging two visual windows 21 with different angles, when the vacuum chamber 11 is observed from one visual window 21, the other visual window 21 is used for light transmission, and external light is injected from the other visual window 21, which increases the light intensity in the vacuum chamber 11 and facilitates the observation of the situation in the vacuum chamber 11. In addition, the vacuum chamber 11 can be observed from two different angles, with a wider observation range, and the blind area can be reduced as much as possible.

[0049] Furthermore, a fill light 22 is arranged on the cover 2 . The fill light 22 is arranged at one of the visible windows 21 , and the fill light 22 is arranged toward the visible window 21 .

[0050] It is understandable that when the vacuum chamber 11 cannot be clearly observed through natural light, a fill light 22 is used to fill light into the vacuum chamber 11 through one of the visible windows 21 to increase the light intensity in the vacuum chamber 11 and facilitate observation of the situation in the vacuum chamber 11.

[0051] In some embodiments, a limit block 51 is arranged on the upper part of the support platform 5, and the limit block 51 is detachably connected to the support platform 5 by bolts. Specifically, the limit block 51 is in a right angle shape, and four limit blocks 51 are arranged. The four limit blocks 51 are arranged at the four corners of the support platform 5, respectively, and are arranged at right angles toward the inside of the support platform. The limit block 51 is used to limit the liquid tray 4 to prevent the liquid tray 4 from moving on the support platform under the interference of external forces.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
