Description

Technical Field

[0001] This invention belongs to the technical field of transformer production equipment, specifically relating to the production of transformer cores, and particularly to a core spraying device for transformer production. Background Technology

[0002] Three-phase transformers are designed to handle different input voltages. Multiple input windings can be used to accommodate different input voltages, and multiple windings can also be used to output different voltages. These three independent windings, connected in different ways, supply three-phase AC power. The core of a three-phase transformer forms the transformer's magnetic circuit and also acts as the transformer's framework. The core is typically made of silicon steel sheets, a type of steel containing silicon (silicon is also called silicide), with a silicon content ranging from 0.8% to 4.8%. Silicon steel is used for the transformer core because it is a highly permeable magnetic material. In a energized coil, it can generate a large magnetic induction intensity, allowing for a smaller transformer size. To reduce core losses, its surface needs to be coated. Currently, there are some problems with the impregnation coating process for the core: When applying coating to iron cores using existing equipment, it is impossible to apply coating to multiple iron cores, thus affecting production efficiency. After the iron core is dip-coated, there will be excess insulating varnish on the surface of the iron core. If the iron core is dried directly, the drying time will be long.

[0003] For example, a three-phase transformer core spraying processing equipment and method disclosed in CN112871554B includes a base plate, a rotating device, a drying device, and an immersion chamber. The rotating device is fixedly installed on the left side of the upper surface of the base plate, and the drying device is fixedly connected to the base plate on the right side of the rotating device. An immersion chamber is placed above the base plate at the lower part of the rotating device. This invention achieves continuous sequential immersion coating of cores in multiple working chambers by activating a drive motor, whose output drives a central rotating rod. The drive motor rotation moves a reciprocating frame to dry the cores in the working chambers that are transferred out of the immersion chamber. This allows the reciprocating frame movement to coordinate with the rotating disc, facilitating the drying of cores in each transferred-out working chamber. Pulling the contact rod to the right separates each core, preventing overlapping of unblocked cores during immersion and avoiding uneven coating of some cores.

[0004] The above technical solutions still have some problems in practical applications. The dip coating process of the iron core is relatively simple, and the insulating varnish is difficult to penetrate into the gaps of the iron core, so it is difficult to guarantee the coating effect. In order to solve these problems, an iron core spraying device for transformer production is proposed. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0006] To this end, the present invention proposes a core coating device for transformer production. This core coating device has the advantage of performing wave-like motion under the guidance of a sliding component to improve the contact effect between the core body and the insulating varnish, thereby improving the coating effect of the core body.

[0007] According to an embodiment of the present invention, a core coating device for transformer production includes: a coating box, a slide rail, a slide table assembly, a drive assembly, and a sliding assembly; the coating box contains insulating coating material; the slide rail is disposed inside the coating box; the slide table assembly is used to place the core body, the slide table assembly is slidably connected to the slide rail, and the slide rail guides the slide table assembly; the drive assembly is used to drive the slide table assembly to move intermittently; the sliding assembly is disposed between the slide table assembly and the slide rail, and the sliding assembly includes: multiple guide grooves, positioning grooves, and guide blocks; the multiple guide grooves are all disposed on the slide rail, and the multiple guide grooves are arranged along the moving direction of the slide table assembly; the positioning groove is disposed on the slide table assembly and overlaps the slide rail; the guide block is disposed in the positioning groove, and the guide block is slidably connected to the guide groove. During the process of the drive assembly driving the slide table assembly to move, the cooperation between the guide block and the guide groove enables the slide table assembly to complete curved sliding, thereby improving the contact effect between the core body and the insulating coating.

[0008] By intermittently driving the slide assembly with the drive component, the immersion time of the iron core in the insulating coating is increased, thus improving the coating effect. The sliding component enables the iron core to slide along a curved path, and when the slide assembly loses power, it slides in the opposite direction along the inclined inner wall of the guide groove, thereby enhancing the coating effect of the insulating varnish.

[0009] According to one embodiment of the present invention, both ends of the slide rail are provided with support plates, and the bottom of the support plate is provided with a lifting component, which can drive the support plate to move up and down reciprocally.

[0010] The lifting assembly is a linear actuator, such as a cylinder. When the lifting assembly is a cylinder, the cylinder is fixed below the slide rail, and the output end of the cylinder passes through the slide rail and is fixedly connected to the pallet. The lifting assembly drives the pallet to move up and down reciprocally, which is used to load and unload the iron core body.

[0011] According to one embodiment of the present invention, a groove is formed on the upper surface of the slide rail, the groove is located between two support plates, a plurality of guide grooves are arranged at the bottom of the groove, the guide grooves are "V" shaped, the bottom of the guide grooves are formed with rounded chamfers, and adjacent guide grooves are smoothly connected.

[0012] Multiple grooves form a wave-shaped surface to achieve a wave-shaped movement path during the process of the drive component pushing the slide assembly, thereby extending the movement path of the slide assembly within a limited space and improving the coating effect.

[0013] According to one embodiment of the present invention, the driving assembly includes: a connecting seat, a movable block, an extension seat, and a drive motor; the movable block is fixed to the upper surface of the connecting seat, and there are multiple movable blocks, which are spaced apart along the length direction of the slide assembly; the extension seat is fixed to the lower end of the connecting seat, and there are two extension seats, which are spaced apart along the length direction of the slide assembly; movable arms are rotatably connected to both sides of the extension seat, and an extension box is formed at the bottom of the coating box, with the other end of the movable arm rotatably connected to the side wall of the extension box; the drive motor is fixedly installed on the outside of the extension box, and the output end of the drive motor is fixedly connected to one of the movable arms.

[0014] Multiple active blocks can simultaneously drive multiple slide components.

[0015] According to one embodiment of the present invention, there are two transmission rods, two synchronous pulleys, and a synchronous belt; the two transmission rods are located on opposite sides of the drive motor, and the two transmission rods are respectively connected to two movable arms on the extension seats. One end of the movable arm is connected to the extension seat, and the other end is fixedly connected to one end of the transmission rod; the number of synchronous pulleys is [number missing], and the two synchronous pulleys are respectively fixedly connected to the other end of the transmission rod; the synchronous belt is drivenly connected to the two synchronous pulleys to ensure that the multiple movable arms rotate synchronously.

[0016] According to one embodiment of the present invention, the upper end of the contact surface between the movable block and the slide assembly is formed with an inclined surface, and the inclined structure of the inclined surface is provided to facilitate the movable block to push the base plate.

[0017] If a slight positional deviation occurs when the moving block contacts the slide assembly, the tilted surface allows the slide assembly to slide down along the tilted surface, thus achieving automatic alignment and reducing the requirement for high accuracy in the relative position of the moving block and the slide assembly.

[0018] According to one embodiment of the present invention, the slide assembly includes: a base plate, a top plate, and a movable seat; the base plate is slidably mounted above a slide rail; a positioning groove is formed on the lower surface of the base plate, and a guide block is fixedly mounted inside the positioning groove; the top plate is mounted above the base plate, and the top plate is configured as a mesh plate; the movable seat is fixedly mounted at the bottom end of the top plate.

[0019] According to one embodiment of the present invention, a flow guiding assembly is installed between the movable seat and the top plate. The flow guiding assembly includes a through groove and a flow guiding plate. The through groove is opened through the middle of the movable seat, and the flow guiding plate is fixedly installed at the groove of the movable seat. The flow guiding plate is configured as a "∧" shaped structure.

[0020] By setting a guide plate below the top plate, the inclined structure on both sides of the guide plate allows the insulating varnish to be guided through the top plate during sliding, thereby improving the coating effect of the iron core body.

[0021] According to one embodiment of the present invention, hangers are fixedly installed at both ends of the top plate.

[0022] The installation of the hanger facilitates the lifting of the top plate, thereby facilitating the batch loading and unloading of multiple iron core bodies.

[0023] According to one embodiment of the present invention, supports are fixedly installed at both ends of the upper surface of the base plate, and insert rods are fixedly installed at both ends of the upper surface of the supports; connecting sleeves are fixedly connected to the outer side of the top plate, the number of connecting sleeves is the same as the number of insert rods and they correspond one-to-one, and the connecting sleeves can be fitted onto the insert rods; a positioning seat for assisting in positioning the top plate is fixedly installed at the top of the outer side wall of the support.

[0024] The connection between the insert rod and the connecting sleeve improves the ease of assembly between the bottom plate and the top plate.

[0025] The beneficial effects of this invention are that it employs a slide rail and slide table assembly inside the coating box. The slide table assembly can slide above the slide rail to drive the iron core body to move. The iron core body can complete the coating of insulating varnish while sliding with the slide table assembly. By opening a slide groove and a guide groove above the slide rail, and setting the guide groove to a "V" shaped structure, and setting a positioning groove and a guide block at the bottom of the slide table assembly, the guide block can slide inside the slide groove and perform wave-shaped movement under the guidance of the "V" shaped structure of the guide groove, thereby improving the contact effect between the iron core body and the insulating varnish, and thus improving the coating effect of the iron core body. A movable block is installed on the inner side of the slide rail. The movable block can push the slide assembly to slide, so as to realize the movement of multiple iron core bodies inside the coating box, thereby facilitating the continuous coating of multiple iron core bodies. By setting a connecting seat, an extension seat, and a movable arm at the bottom of the movable block, the movable arm rotates under the drive of the drive motor, and drives the extension seat, the connecting seat, and the movable block to move. As the movable block follows the rotation of the movable arm, it can intermittently push the slide assembly to realize the power input to the slide assembly. Furthermore, the intermittent pushing method allows the slide assembly to slide in the opposite direction along the inclined inner wall of the guide groove after losing power, so as to improve the coating effect of insulating paint. A top plate is installed to support the iron core body. The top plate is designed as a mesh plate, which facilitates the insulating varnish to pass through the top plate from bottom to top to coat the bottom of the iron core body. By setting a guide plate below the top plate, the inclined structure on both sides of the guide plate can guide the insulating varnish through the top plate when sliding, thereby improving the coating effect of the iron core body.

[0032] The following is a reference appendix. Figure 1-10 A detailed description of a transformer core spraying apparatus according to an embodiment of the present invention.

[0033] Example 1: The spraying device includes a coating box 1 for holding insulating coating material, a slide rail 2 installed inside the coating box 1, a slide assembly 3 installed above the slide rail 2, and a drive assembly for moving the slide assembly 3 along the length of the coating box 1. An iron core body 4 is disposed above the slide assembly 3. A box cover 12 is hinged to the top of the coating box 1. There are two slide rails 2, spaced apart along the width of the coating box 1.

[0034] The slide rail 2 is fixedly installed inside the coating box 1. Both ends of the slide rail 2 are provided with support plates 21. The support plates 21 are used to drive the slide table assembly 3 to rise or fall. The upper surface of the slide rail 2 is provided with a groove 22 along the length of the coating box 1. The groove 22 is located between the two support plates 21. By providing the groove 22 above the slide rail 2, the slide table assembly 3 can slide inside the groove 22.

[0035] The drive assembly is used to intermittently push the slide assembly 3 to slide. The drive assembly includes a movable block 24, a connecting seat 241, an extension seat 242, and movable arms 243. The connecting seat 241 is located between two slide rails 2. The movable blocks 24 are fixed to the upper surface of the connecting seat 241. There are multiple movable blocks 24, which are spaced apart along the moving direction of the slide assembly 3. There are two extension seats 242, which are fixedly installed at both ends of the lower surface of the movable blocks 24. Movable arms 243 are rotatably connected to the lower ends of both sides of the extension seats 242, that is, there are four movable arms 243. An extension box 11 is fixedly installed at the bottom of the painting box 1. One end of the four movable arms 243 is rotatably connected to the extension seat 242, and the other end is rotatably connected to the side wall of the extension box 11.

[0036] The drive assembly also includes a drive motor 244, a transmission rod 245, a synchronous pulley 246, and a synchronous belt 247. The drive motor 244 is fixedly installed on the outside of the extension box 11, and the output shaft of the drive motor 244 is fixedly connected to the other end of a movable arm 243. There are two transmission rods 245, and each transmission rod 245 is fixedly connected to a synchronous pulley 246. The synchronous belt 247 is driven and connected to the two synchronous pulleys 246. The two transmission rods 245 are located on opposite sides of the drive motor 244, and the two transmission rods 245 are respectively fixedly connected to the two movable arms 243 on that side. The transmission rods 245 pass through the side wall of the extension box 11, so that the synchronous pulleys 246 are located on the outside of the extension box 11.

[0037] By setting movable blocks 24 on the inner side of the two slide rails 2, the movable blocks 24 can push the slide assembly 3 to slide, so as to realize the movement of multiple sets of iron core bodies 4 inside the coating box 1, thereby facilitating the continuous coating of multiple sets of iron core bodies 4.

[0038] Both ends of the upper surface of the slide rail 2 are provided with grooves 211 corresponding to the support plate 21. A hydraulic rod 212 is fixedly installed at the bottom of the groove 211, and the top end of the hydraulic rod 212 is fixedly connected to the bottom end of the support plate 21. The hydraulic rod 212 can lift the support plate 21 to facilitate the loading and unloading of materials by the slide assembly 3.

[0039] The slide assembly 3 is used to drive the iron core body 4 to slide above the slide rail 2. The slide assembly 3 includes a base plate 31, a top plate 32 and a movable seat 33. The base plate 31 is slidably installed above the slide rail 2, the top plate 32 is installed above the base plate 31 and the top plate 32 is set as a mesh plate, and the movable seat 33 is fixedly installed at the bottom end of the top plate 32.

[0040] Example 2: The difference from Embodiment 1 is that an inclined surface 248 is provided at the top of the side of the movable block 24 that contacts the slide assembly 3. The inclined structure of the inclined surface 248 is used to guide the contact between the movable block 24 and the base plate 31, thereby ensuring that the movable block 24 can automatically adapt when it is misaligned with the base plate 31.

[0041] Example 3: The difference from Embodiment 1 is that a sliding assembly is formed between the base plate 31 and the slide rail 2. The sliding assembly guides the sliding of the slide assembly 3. The sliding assembly includes a guide groove 23, a positioning groove 311, and a guide block 312. Multiple guide grooves 23 are formed at the bottom of the slide groove 22 along the length of the coating box 1. The multiple guide grooves 23 are set in a "V" shape, and the bottom of the guide groove 23 has a rounded chamfer. The upper end faces of two adjacent guide grooves 23 are connected by a rounded arc. There are two positioning grooves 311. The two positioning grooves 311 are formed on the lower surface of the base plate 31. The two positioning grooves 311 overlap the two slide rails 2. The adaptation of the two positioning grooves 311 and the two slide rails 2 is used to limit the base plate 31 in the width direction of the coating box 1, so that it can move along the length direction of the slide rail 2 when pushed. The guide block 312 is fixedly installed inside the positioning groove 311, and the guide block 312 is slidably connected to the guide groove 23. When the drive assembly drives the base plate 31 to move, the guide block 312 moves along the waveform surface formed by multiple guide grooves 23 to achieve the waveform sliding effect of the base plate 31.

[0042] Example 4: The difference from Embodiment 1 is that a flow guiding assembly is installed between the movable seat 33 and the top plate 32. The flow guiding assembly is used to guide the insulating coating through the top plate 32. The flow guiding assembly includes a through groove 331 and a flow guiding plate 332. The through groove 331 is opened through the middle of the movable seat 33, and the flow guiding plate 332 is fixedly installed at the groove of the movable seat 33. The flow guiding plate 332 is set with a "∧" shaped structure. The "∧" shaped structure design facilitates the guidance of the insulating paint.

[0043] The four corners of the lower surface of the movable seat 33 are all fixedly installed with traveling wheels 333, and the traveling wheels 333 are set as universal wheels. The setting of the traveling wheels 333 facilitates the movement and sliding of the top plate 32 after the device is taken out.

[0044] Supports 313 are fixedly installed at both ends of the upper surface of the base plate 31, and insert rods 314 are fixedly installed at both ends of the upper surface of the support 313. A connecting sleeve 315 is fixedly installed on the outer side of the top plate 32, and the connecting sleeve 315 is sleeved on the insert rod 314. A positioning seat 316 for assisting in positioning the top plate 32 is fixedly installed at the top of the outer wall of the support 313. The positioning seat 316 can play an auxiliary positioning role between the support 313 and the top plate 32, so as to facilitate the placement of the top plate 32.

[0045] Both ends of the upper surface of the top plate 32 are fixedly installed with hangers 321 for moving the slide assembly 3. The hangers 321 facilitate the lifting out of the top plate 32, thereby facilitating the loading and unloading of the iron core body 4.

[0046] In summary, when this device is used to coat the transformer core with insulating varnish, the core body 4 can be placed above the slide assembly 3, and the slide assembly 3 can slide above the slide rail 2 to drive the core body 4 to slide inside the coating box 1. During the sliding process, the core body 4 is in full contact with the insulating varnish inside the coating box 1 to ensure the coating effect of the core body 4.

[0047] During this process, the drive motor 244 can drive the movable arm 243 to rotate, the movable arm 243 drives the extension seat 242 and the connecting seat 241 to rotate, and the connecting seat 241 drives the movable block 24 to rotate, so that multiple movable blocks 24 make circular motion inside the coating box 1. During the rotation, the movable block 24 can push the base plate 31 to move, so that the base plate 31 moves up and down and forward above the slide rail 2, so as to realize the horizontal conveying of the slide assembly 3 and the iron core body 4.

[0048] During the movement of the iron core body 4, the slide assembly 3 drives the guide block 312 to slide in the slide groove 22. The guide block 312 moves along the guide groove 23 inside the slide groove 22. The "V" shaped structure design of the guide groove 23 allows the guide block 312 to perform wave-like motion, thereby improving the contact effect between the iron core body 4 and the insulating varnish. Furthermore, since the base plate 31 performs intermittent motion, when the base plate 31 is separated from the movable block 24, the base plate 31 can slide forward or backward along the inner wall of the guide groove 23 in a wave-like motion. By setting the wave-like path, the movement path of the iron core body 4 is increased, thereby improving the contact effect between the iron core body 4 and the insulating varnish. When the core body 4 is being unloaded, the hydraulic rod 212 can lift the support plate 21 at one end of the slide rail 2 upwards, and the core body 4 can be placed directly on the top plate 32. The top plate 32 and the movable seat 33 can be placed on the bottom plate 31, and the bottom plate 31 can be placed on the lifted support plate 21. Then the hydraulic rod 212 drives the support plate 21 to move down and return to its original position, so as to realize the unloading of the core body 4. After the core body 4 is coated, the support plate 21 can lift the bottom plate 31. At this time, the excess insulating paint slides off freely, which facilitates the subsequent processing of the transformer core. Then the core body 4 is taken out, and the unloading is completed.
