Description

Technical Field

[0001] The present invention relates to the technical field of magnetic core processing, and in particular to a magnetic core cutting device capable of automatically loading and unloading materials. Background Art

[0002] In the field of modern electronic component manufacturing, magnetic cores are important magnetic material components and are widely used in electronic devices such as transformers and inductors. Toroidal cores are very common on the market. Sometimes, to meet specific usage requirements, a toroidal core needs to be cut into two equal-sized half-toroidal cores.

[0003] Chinese patent publication number CN114012168B discloses a magnetic core cutting device capable of positioning magnetic cores. Multiple annular magnetic cores can be placed and positioned by annular grooves in multiple fixed circular plates, and then multiple cutting rollers are moved downward to cut the annular magnetic cores.

[0004] However, the aforementioned devices, as well as most current core cutting equipment, still rely on manual loading, clamping, and installation of the cores during processing. After the cores are cut, they must also be manually removed. This manual operation has numerous drawbacks. Firstly, the manual loading and unloading process consumes significant time and labor costs, resulting in low production efficiency and difficulty meeting the needs of large-scale production. Secondly, manual operation presents significant safety risks, as operators come into close contact with the cutting equipment during operation, making accidental injuries more likely. Summary of the Invention

[0008] Furthermore, the guide structure includes a sliding pin and a guide plate. The two guide plates are respectively installed on both sides of the top of the chain conveyor and are located on both sides of the cutting blade. The two guide plates are close to each other and are respectively provided with a guide groove. The guide groove includes a sunken portion and an entrance portion connected to both ends of the sunken portion. The height of the sunken portion is lower than the height of the entrance portion. Side openings are respectively provided on both sides of the clamping seat. The sliding pin is installed on the driving rod and passes through the side opening. The first spring can lift the driving rod so that the height of the sliding pin is flush with the height of the entrance portion.

[0009] Furthermore, a circular arc abutting surface is provided on the top of the inner end of the positioning slider.

[0010] Furthermore, an arc clamp is provided at the outer end of the positioning slider.

[0011] Furthermore, the bottom of the receiving groove is provided with an avoidance groove on the path of the cutting blade. Furthermore, it also includes a cleaning mechanism, which includes a fan, a second rack and a second gear.

DETAILED DESCRIPTION

[0017] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0018] like Figure 1-5 As shown, the present embodiment provides a magnetic core cutting device that can automatically load and unload materials, including a chain conveyor 1, on which a chain belt 11 is arranged, and the chain belt 11 is connected by multiple chain strips 111. The chain conveyor 1 is a prior art equipment, so its specific structure will not be described in detail. The present invention also includes a side frame 2, a clamping seat 3, a positioning mechanism 4 and a unloading mechanism 5.

[0019] A cutter 21 is installed on the side frame 2. The cutter 21 is located above the conveying path of the chain plate belt 11 and is installed with a cutting blade 22. The cutter 21 is started to rotate the cutting blade 22 and can cut the magnetic core passing through the cutting blade 22.

[0020] There are multiple clamping seats 3 set along the path surface of the chain belt 11. Specifically, the clamping seat 3 is fixedly installed on the chain strip 111. A receiving groove 31 is provided on the top of the clamping seat 3 to accommodate the magnetic core. Cutting openings 32 for the cutting blade 22 to pass through are provided at both ends of the clamping seat 3. Positioning grooves 33 are provided on both sides of the receiving groove 31. When the clamping seat 3 is transported through the cutting blade 22 with the chain belt 11, the cutting blade 22 will pass through the cutting opening 32 to cut the magnetic core in the receiving groove 31 into half.

[0021] Preferably, an avoidance groove 311 is provided at the bottom of the accommodating groove 31 on the path of the cutting blade 22 , so that the cutting blade 22 can completely cut the magnetic core without causing damage to the bottom of the accommodating groove 31 .

[0022] The positioning mechanism 4 includes a positioning slider 41, a rotating shaft 42 and a driving assembly 43. The two positioning sliders 41 are slidably installed in the two positioning slots 33 along the direction close to or away from the center of the accommodating slot 31, and are used to clamp the magnetic core in the center. The two rotating shafts 42 are rotatably installed on both sides of the top of the clamping seat 3. A connecting rod 421 is provided on the rotating shaft 42, and a pressure block 422 is provided at the far end of the connecting rod 421. The pressure block 422 is used to press the top of the magnetic core to prevent the magnetic longitudinal shaking during cutting. The driving assembly 43 can drive the positioning slider 41 to move and drive the connecting rod 421 to rotate close to or away from the top of the accommodating slot 31.

[0023] Preferably, an arc clamping plate 413 is provided at the outer end of the positioning slider 41 , and the curvature of the arc clamping plate 413 is adapted to the curvature of the edge of the magnetic core, which is conducive to better centering and clamping the magnetic core.

[0024] Specifically, the driving assembly 43 includes a driving rod 431 and a guide structure. The top of the positioning groove 33 is provided with a driving groove 331 that passes through to the top of the clamping seat 3. The driving rod 431 is slidably installed in the driving groove 331. The side of the driving rod 431 close to the positioning slider 41 is provided with a push portion 432. The bottom of the push portion 432 is thinned. Figure 4 As shown, the push portion 432 forms a smooth transition with the thinned portion at its bottom. A second spring 411 is connected between the inner end of the positioning slider 41 and the inner wall of the positioning groove 33 to provide an elastic force to pull the positioning slider 41 into the positioning groove 33, causing the positioning slider 41 to abut against the push portion 432. A first gear 423 is provided on the rotating shaft 42, and a first rack 433 is provided on the driving rod 431 to mesh with the first gear 423. A first spring 434 is connected between the bottom end of the driving rod 431 and the bottom of the positioning groove 33. The first spring 434 can provide an elastic force to push the driving rod 431 out of the top of the driving groove 331, so that the positioning slider 41 abuts the thinned portion of the push portion 432 and drives the pressure block 422 to flip away from the top of the accommodating groove 31. The guide structure can drive the driving rod 431 to move into the driving groove 331.

[0025] Furthermore, the guiding structure includes a sliding pin 435 and a guide plate 436. The two guide plates 436 are respectively installed on both sides of the top of the chain conveyor 1 and are located on both sides of the cutting blade 22. The two guide plates 436 are close to each other on one side and a guide slot 437 is respectively provided. The guide slot 437 includes a sunken portion 4371 and an entrance portion 4372 connected to both ends of the sunken portion 4371. The height of the sunken portion 4371 is lower than the height of the entrance portion 4372, and the sunken portion 4371 is smoothly connected with the entrance portion 4372 at both ends. Side openings 34 are respectively provided on both sides of the clamping seat 3. The sliding pin 435 is installed on the driving rod 431 and passes through the side opening 34. The first spring 434 can lift the driving rod 431 so that the height of the sliding pin 435 is flush with the height of the entrance portion 4372.

[0026] The unloading mechanism 5 is used to transfer the cut magnetic core in the clamping seat 3.

[0027] Specifically, the unloading mechanism 5 includes a baffle 51 and a unloading conveyor 52. The baffle 51 is installed on the bracket. The baffle 51 is arc-shaped and surrounds the periphery of the conveying path at one end of the chain conveyor 1. The lower end of the baffle 51 extends to the bottom of the chain conveyor 1. The unloading conveyor 52 is located below the chain conveyor 1 and one side of its top surface is in contact with the lower end of the baffle 51.

[0028] When the equipment is working, the chain conveyor 1 drives the clamping seat 3 to circulate and transport. When the clamping seat 3 has not passed the guide plate 436, the first spring 434 pushes the driving rod 431 out of the driving groove 331, so that the positioning slider 41 abuts against the thinned bottom part of the push portion 432. The two positioning sliders 41 are in a state of being away from each other, and the driving rod 431 drives the rotating shaft 42 to rotate to a state where the pressure block 422 is away from the top of the receiving groove 31 through the first rack 433 and the first gear 423. This state is the initial state, and the staff can directly put the magnetic core to be cut into the receiving groove 31; when the clamping seat 3 passes the guide plate In the area 436, the sliding pin 435 will slide into the sunken portion 4371 through the entrance portion 4372 and thereby drive the driving rod 431 to move downward, thereby synchronously driving the positioning slider 41 to move and the rotating shaft 42 to rotate. First, the downward movement of the pushing portion 432 will cause the positioning slider 41 to immediately leave the thinning area of ​​the pushing portion 432, and then the pushing portion 432 will push the positioning slider 41 toward the magnetic core. The two positioning sliders 41 will move synchronously to push the magnetic core toward the middle of the accommodating groove 31, thereby achieving centering and clamping of the magnetic core. Subsequently, the rotating shaft 42 will continue to rotate to make the pressure block 422 approach the magnetic core that has been clamped in the center, thereby achieving compression of the magnetic core. As the clamping seat 3 moves, the clamped magnetic core will be cut in half by the cutting blade 22 and then transported to the end of the chain conveyor 1. When the clamping seat 3 leaves the area of ​​the guide plate 436, the sliding pin 435 leaves the guide slot 437, and under the action of the first spring 434, the positioning slider 41 and the pressure block 422 return to their initial state, canceling the clamping of the magnetic core; when the clamping seat 3 flips downward from the end of the chain conveyor 1 along with the chain belt 11, the baffle 51 will support the magnetic core in the accommodating groove 31 until the magnetic core moves away from the lower end of the baffle 51 along with the clamping seat 3 and is located above the unloading conveyor 52, and the magnetic core will fall onto the unloading conveyor 52 for transportation and transfer.

[0029] It should be noted that the stroke of the positioning slider 41 from the initial state to the centering and clamping of the magnetic core should be smaller than the stroke of the pressure block 422 pressing the top of the magnetic core, so that the positioning slider 41 can clamp the magnetic core before the pressure block 422, achieving the clamping effect of centering first and then pressing.

[0030] The present invention utilizes the chain conveyor 1 to drive the clamping seat 3 to circulate the magnetic core, which can continuously send each magnetic core to be cut into the cutting area of ​​the cutting blade 22 for cutting, which can greatly improve the efficiency of the magnetic core cutting process; the positioning mechanism 4 is utilized, so that when the clamping seat 3 passes through the guide plate 436 area, it can automatically drive the positioning slider 41 and the pressure block 422 through the driving component 43 to clamp the magnetic core in the center in succession, thereby realizing the center positioning and stable clamping of the magnetic core, ensuring the accurate cutting position, and no manual clamping is required, further improving the processing efficiency. The staff puts the magnetic core into the accommodating groove 31 before the clamping seat 3 enters the cutting area, which can leave a larger safety distance between the cutting blade 22 and the staff, reducing safety hazards.

[0031] Preferably, a circular arc abutment surface 412 is provided at the top of the inner end of the positioning slider 41. When the driving rod 431 moves downward, the positioning slider 41 can move and transition by contacting the push portion 432 through the circular arc abutment surface 412, thereby reducing the resistance of the positioning slider 41 leaving the thinned portion of the push portion 432.

[0032] In one embodiment, a cleaning mechanism 6 is further included, which includes a fan 61, a second rack 62 and a second gear 63. The two second racks 62 are respectively slidably installed at the two ends of the clamping seat 3, and the two second gears 63 are respectively coaxially connected to the rotating shaft 42 and meshed with the corresponding second racks 62. A fan 61 is installed on each second rack 62, and an air outlet 611 is provided on the fan 61. The end of the air outlet 611 is located outside the cutting opening 32. When the clamping seat 3 is not in the guide plate 436 area, the air outlet 611 will face the outside of the cutting port 32 to blow wind into the receiving groove 31, thereby removing the cutting debris in the receiving groove; when the clamping seat 3 enters the guide plate 436 area to prepare for cutting the magnetic core, the rotating shaft 42 is driven to rotate by the driving rod 431, and the fan 61 is driven to move through the engagement of the second gear 63 and the second rack 62, so that the end of the air outlet 611 can be moved laterally away from the cutting port 32 to avoid the cutting blade 22 that is about to pass by.

[0033] Preferably, an air discharge bin 64 is provided at the end of the air outlet 611, and a strip hole 641 is longitudinally opened on the side of the air discharge bin 64 facing the cutting opening 32. When the magnetic core is cut, the end of the air outlet 611 returns to the outside of the cutting opening 32 as the clamping seat 3 moves away from the guide plate 426. The strip hole 641 can blow air towards the gap after the magnetic core is cut, thereby blowing away the debris generated after cutting.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
