Description

Technical Field

[0001] This utility model relates to the field of nanocrystalline iron core production technology, specifically a nanocrystalline iron core heating, curing and packaging machine. Background Technology

[0002] Nanocrystalline iron cores are soft magnetic materials formed from iron-based alloys through rapid solidification and heat treatment. Their internal grain size is at the nanoscale, dispersed within an amorphous matrix. This material possesses excellent properties such as high saturation magnetic induction, high initial permeability, low high-frequency loss, and high Curie temperature. It can significantly improve the power density, efficiency, and temperature stability of power electronic devices such as transformers and inductors, and is widely used in fields such as inverters for new energy vehicles, charging piles, and electromagnetic compatibility devices. During the production process of nanocrystalline iron cores, to improve the mechanical strength, insulation performance, and heat dissipation efficiency of the core, ensuring its... Stable operation in high-frequency electromagnetic environments requires heat curing and encapsulation of nanocrystalline iron cores, necessitating the use of a nanocrystalline iron core heat curing and encapsulation machine. Existing nanocrystalline iron core heat curing and encapsulation machines typically consist of a curing mechanism and a scraping mechanism. The curing mechanism comprises a hydraulic cylinder, a curing plate, and a heating plate, while the scraping mechanism consists of a vertically movable annular scraper. The process involves two steps: first, the nanocrystalline iron core, already coated with adhesive and placed in an insulating encapsulation box, is moved above the lower curing plate. Simultaneously, the hydraulic cylinder moves downwards, causing the upper curing plate to move synchronously. At the same time, the heating plate dissipates heat, and the nanocrystalline iron core... Pressurization is applied between two curing plates, while a heating plate heats the encapsulation box and nanocrystalline core, causing the encapsulating adhesive to flow evenly across their surfaces. Combined with hydraulic cylinder pressure, excess adhesive overflows from the gaps in the center of the encapsulation box's outer surface. After a period of time, the encapsulation box and nanocrystalline core are heated to a suitable temperature, at which point the adhesive undergoes a cross-linking reaction and rapidly cures. The cured nanocrystalline core is then moved under a ring scraper, which removes the excess adhesive from the outer surface of the encapsulation box, completing the curing and encapsulation process for the nanocrystalline core. Traditional nanocrystalline iron core heat curing and packaging machines require two stations for heat curing and scraping off excess packaging adhesive. Different sizes of nanocrystalline iron cores require different sized annular scrapers for scraping off excess adhesive, resulting in low packaging efficiency. Scraping off excess adhesive with an up-and-down moving annular scraper only requires one up-and-down movement, leaving adhesive burrs that can easily remain below the seams on the outer surface of the packaging box, affecting the overall aesthetics of the iron core. Therefore, we propose a nanocrystalline iron core heat curing and packaging machine. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a nanocrystalline iron core heating and curing packaging machine. This machine can adjust the scraping of packaging adhesive on the surface of nanocrystalline iron core packaging boxes of different sizes. Heating and curing and scraping of overflowing adhesive are performed at one station. After the adhesive has cured, the scraping work can be carried out. The nanocrystalline iron core is rotated to scrape the packaging adhesive on the surface of the packaging box. The overflowing packaging adhesive can be scraped off multiple times, avoiding the existence of adhesive burrs and improving the packaging efficiency of nanocrystalline iron cores. This effectively solves the problems in the background art.

A groove is opened in the middle of the interior of the mounting beam. The rack plate is slidably connected to the inside of the groove. The rack plate and the gear mesh with each other, providing a basis for the linkage between the heating curing and scraping operations. The scraping assembly is respectively located on the left and right sides of the front end of the mounting beam. It can be adjusted to adapt to the scraping of the encapsulating adhesive on the surface of nanocrystalline iron core packaging boxes of different sizes. Heating curing and scraping of overflowing adhesive are located in one station. After the adhesive is cured, the scraping operation can be performed. The encapsulating adhesive on the surface of the packaging box is scraped by rotating the nanocrystalline iron core. The overflowing encapsulating adhesive can be scraped multiple times, avoiding the existence of adhesive burrs and improving the encapsulation efficiency of the nanocrystalline iron core.

[0007] Furthermore, the scraping assembly includes a mounting plate, a mounting bracket, pressure rollers, and scrapers. The mounting plate is slidably connected to the left and right ends of the front side of the mounting beam. The middle of the rear side of the mounting plate is threaded to the outer surface of the bidirectional lead screw. The mounting brackets are slidably connected to the middle of the front side of the mounting plate. The pressure rollers are rotatably connected to the upper and lower ends inside the mounting brackets. The scrapers are all located in the middle of the side of the mounting bracket near the middle of the encapsulation base. The pressure rollers and the vertically adjacent scrapers are installed together to provide a basis for scraping off the overflowing encapsulation adhesive.

[0008] Furthermore, the scraping assembly also includes a lead screw and a knob. The lead screw is rotatably connected to the middle of the inner front side of the mounting plate, and the outer surface of the lead screw is threaded to the middle of the inner side of the vertically adjacent mounting bracket. The knob is located on the side of the lead screw away from the middle of the packaging machine base, and can be adjusted by rotating the knob to accommodate nanocrystalline iron cores of different sizes.

[0009] Furthermore, both the first curing plate and the second curing plate are equipped with heating plates inside. The input end of the heating plate is electrically connected to the output end of the microcontroller, providing a basis for the heating and curing of the encapsulating adhesive.

[0010] Furthermore, it also includes a hydraulic cylinder, which is located in the middle of the upper front side inside the mounting beam. The hydraulic cylinder is connected to an external hydraulic pump station through an oil pipe. The lower end of the outer surface of the extension end of the hydraulic cylinder is rotatably connected to the upper inner end of the curing plate. The rack plate is fixedly connected to the middle of the outer surface of the extension end of the hydraulic cylinder through the connecting plate above, providing a pressurizing effect for the encapsulation of the nanocrystalline iron core.

[0011] Furthermore, it also includes a motor, which is located in the middle of the top wall of the packaging base. The input end of the motor is electrically connected to the output end of the microcontroller, and the upper end of the output shaft of the motor is fixedly connected to the lower end of the curing plate, providing a stable drive for the rotation of the nanocrystalline iron core.

[0012] Furthermore, it also includes a microcontroller, which is located on the upper right side of the front of the packaging base. The input terminal of the microcontroller is electrically connected to an external power supply to provide control for the heating, curing, and packaging of the nanocrystalline iron core.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This nanocrystalline iron core heating curing and packaging machine has the following advantages:

[0014] The meshing of the rack and pinion plates and gears causes the bidirectional lead screw to rotate synchronously as the curing plate moves downward, thereby driving the mounting bracket to move inward synchronously. With the adjustment of the lead screw, the pressure roller and scraper can simultaneously contact the left and right sides of the nanocrystalline iron core packaging box, adapting to nanocrystalline iron cores of different sizes. This achieves linkage between the heating and curing process and the adhesive scraping, allowing the adhesive to be scraped off immediately after curing, avoiding the presence of adhesive burrs and eliminating the need to move the nanocrystalline iron core to the next station for scraping, thus improving the packaging efficiency of the nanocrystalline iron core.

[0023] Adjustable curing mechanism 5: It includes a bidirectional lead screw 51, a gear 52, a rack plate 53, and a scraping assembly 54. The bidirectional lead screw 51 is rotatably connected to the middle of the rear side of the mounting beam 2. The gear 52 is located in the middle of the outer surface of the bidirectional lead screw 51. A groove is opened in the middle of the interior of the mounting beam 2. The rack plate 53 is slidably connected to the inside of the groove. The rack plate 53 and the gear 52 are meshed and connected, providing a basis for the linkage between the heating curing operation and the scraping operation. The scraping assembly 54 is respectively located on the left and right sides of the front end of the mounting beam 2. The scraping assembly 54 includes a mounting plate 541, a mounting frame 542, a pressure roller 543, and a scraper 544. The mounting plate 541 is slidably connected to the left and right ends of the front side of the mounting beam 2. The middle of the rear side of the mounting plate 541 is connected to the bidirectional lead screw 51. The outer surface of rod 51 is threaded. A corrugated tube is provided between the inner wall of mounting beam 2 and mounting plate 541. The corrugated tube is sleeved on the outer surface of the bidirectional screw 51. The corrugated tube can contract and expand as the mounting plate 541 moves left and right. Mounting brackets 542 are slidably connected to the middle of the front side inside the mounting plate 541. Pressure rollers 543 are rotatably connected to the upper and lower ends inside the mounting brackets 542. The pressure rollers 543 are made of high-wear-resistant polyurethane. Scrapers 544 are located in the middle of the mounting bracket 542 near the center of the encapsulation base 1. The pressure rollers 543 are installed in conjunction with the vertically adjacent scrapers 544. The outer edge of the pressure roller 543 and the blade of the vertically adjacent scraper 544 are tightly aligned on the same horizontal plane to remove overflowing encapsulation adhesive. The scraping assembly 54 provides a foundation and includes a lead screw 545 and a knob 546. The lead screw 545 is rotatably connected to the center of the front side of the mounting plate 541. The outer surface of the lead screw 545 is threadedly connected to the center of the vertically adjacent mounting bracket 542. A second corrugated tube is provided between the inner wall of the mounting plate 541 and the mounting bracket 542. The second corrugated tube is sleeved on the outer surface of the lead screw 545 and can contract and expand as the mounting bracket 542 moves left and right. The knob 546 is located on the side of the lead screw 545 away from the center of the encapsulation base 1 and can be adjusted by rotating the knob 546 to accommodate different sizes of nanocrystalline iron cores. Both the curing plate 1 3 and the curing plate 2 4 have heating plates 55 inside. The input end of the heating plate 55 is electrically connected to a single... The output end of the microcontroller 8, the outer surfaces of curing plate 3 and curing plate 4 are all equipped with conductive slip rings, the upper middle part of the packaging base 1 is equipped with contact head 1, and the lower front side of the outer surface of the telescopic end of the hydraulic cylinder 6 is equipped with contact head 2. Contact head 1 and contact head 2 are slidably connected to the outer surfaces of the longitudinally adjacent conductive slip rings. The input ends of contact head 1 and contact head 2 are electrically connected to the output end of the microcontroller 8. The input end of the heating plate 55 is electrically connected to the output end of the conductive slip ring for transmitting electrical signals. The outer surface of the heating plate 55 is made of ceramic material and contains uniformly distributed resistance wires. When the heating plate 55 is working, the resistance wires heat up and heat the outer ceramic plate, thereby heating the nanocrystalline iron core. The interior of curing plate 3 and curing plate 4 are equipped with external temperature sensor probes.The input ends of the temperature sensor probes are all electrically connected to the output ends of the conductive slip rings to detect the temperature of the heating plate 55, providing a basis for the heating and curing of the encapsulating adhesive. It also includes a hydraulic cylinder 6, which is located in the middle of the upper front side inside the mounting beam 2. The hydraulic cylinder 6 is connected to an external hydraulic pump station via oil pipes. The lower end of the outer surface of the telescopic end of the hydraulic cylinder 6 is rotatably connected to the upper inner end of the curing plate 4. The rack plate 53 is fixedly connected to the middle of the outer surface of the telescopic end of the hydraulic cylinder 6 via the connecting plate above, providing pressure for the encapsulation of the nanocrystalline iron core. It can be adjusted to adapt to the scraping of encapsulating adhesive on the surface of nanocrystalline iron core encapsulation boxes of different sizes. Heating and curing and scraping of overflowing adhesive are performed at one station. After the adhesive has cured, scraping can be performed. By rotating the nanocrystalline iron core, the encapsulating adhesive on the surface of the encapsulation box is scraped off. Overflowing encapsulating adhesive can be scraped off multiple times, avoiding the presence of adhesive burrs and improving the encapsulation efficiency of the nanocrystalline iron core.

[0024] The working principle of the nanocrystalline iron core heat curing and encapsulation machine provided by this utility model is as follows: When performing the nanocrystalline iron core heat curing and encapsulation operation, adjustments are first made according to the size of the nanocrystalline iron core. Rotating knob 546 drives the lead screw 545 to rotate. Because the outer surface of the lead screw 545 is connected to the internal central thread of the vertically adjacent mounting bracket 542, when the lead screw 545 rotates clockwise, the mounting bracket 542 moves inward, and the distance between the two scrapers 544 decreases, which can accommodate small-sized nanocrystalline iron cores. When the lead screw 545 rotates counterclockwise, the mounting bracket 542 moves outward, and the distance between the two scrapers 544 increases, which can accommodate large-sized nanocrystalline iron cores. The nanocrystalline iron core, already coated with adhesive and placed inside the insulating encapsulation box, is moved above the curing plate 3 below. An external hydraulic pump station operates, and the telescopic end of the hydraulic cylinder 6 moves the curing plate 4 downwards until its lower end is tightly pressed against the upper end of the nanocrystalline iron core encapsulation box, applying pressure to the nanocrystalline iron core. Simultaneously, the microcontroller 8 controls the heating plate 55, which dissipates heat, heating the nanocrystalline iron core and the encapsulation box. The encapsulation adhesive on the surface of the nanocrystalline iron core is also heated. Combined with the pressure from the hydraulic cylinder 6, excess encapsulation adhesive overflows from the gap in the middle of the outer surface of the nanocrystalline iron core encapsulation box. After a period of heating... After plate 55 is heated to a suitable temperature, the encapsulating adhesive undergoes a cross-linking reaction and cures rapidly. Simultaneously, as the telescopic end of hydraulic cylinder 6 moves downward, the connecting plate and rack plate 53 also move downward. Because rack plate 53 is meshed with gear 52, as rack plate 53 moves downward, gear 52 rotates, driving the bidirectional lead screw 51 to rotate. The two mounting plates 541 move inward synchronously, causing mounting bracket 542 to move as well. After the initial adjustment, when the lower end of curing plate 4 is tightly fitted with the upper end of the nanocrystalline iron core encapsulation box, pressure roller 543 and scraper 544 simultaneously contact the left and right sides of the nanocrystalline iron core encapsulation box. Scraper 544 is located at... At the seam of the nanocrystalline iron core packaging box, after the encapsulating adhesive undergoes a cross-linking reaction and cures, the microcontroller 8 controls the motor 7 to operate. The output shaft of the motor 7 drives the curing plate 3 to rotate. Since the nanocrystalline iron core is under pressure at this time, the nanocrystalline iron core is tightly attached to both the curing plate 3 and the curing plate 4. The lower end of the outer surface of the extension end of the hydraulic cylinder 6 is rotatably connected to the upper end of the interior of the curing plate 4. Therefore, as the curing plate 3 rotates, the nanocrystalline iron core and the curing plate 4 also rotate synchronously. At this time, as the nanocrystalline iron core rotates, the encapsulating adhesive overflowing from the seam of the nanocrystalline iron core packaging box will be scraped off by the scraper 544, realizing the heat curing and encapsulation of the nanocrystalline iron core.

[0025] It is worth noting that the microcontroller 8 disclosed in the above embodiments is an STM8S003F3P6TR microcontroller, the heating plate 55 is a YKJRB-210219 heating plate 55, and the motor 7 is a DKM motor. The microcontroller 8 controls the operation of the heating plate 55 and the motor 7 using methods commonly used in the prior art.
