Description

Technical Field

[0001] This utility model relates to the field of magnetic material cutting technology, and more specifically, to a magnetic material green blank cutting device. Background Technology

[0002] Ferrite magnet blanks refer to ferrite materials that have not yet been cut, finished, or magnetized. Currently, a 7mm thick ferrite blank is a relatively long plate, which is cut into multiple shorter blanks using a cutting device. Existing cutting devices typically use wire EDM, but wire EDM corrodes the metal gradually through electro-erosion, resulting in slow cutting speeds. Furthermore, each cut requires manual intervention to advance the ferrite blank a certain distance for further cutting. The entire process is inefficient and lacks automation, making it unsuitable for mass production. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides a magnetic material green blank cutting device, comprising a conveyor, a cutting table, and a laser cutting mechanism. The cutting table has two product track bars spaced apart on its top, each product track bar having a channel for the magnetic material green blank to pass through. The conveyor is adapted to simultaneously transport two magnetic material green blanks, so that the two green blanks are respectively inserted into the two channels. The laser cutting mechanism includes a linear module drive assembly and a laser cutting head mounted on the top of the cutting table. The linear module drive assembly is connected to the laser cutting head to drive the laser cutting head to move and cut the two magnetic material green blanks exiting from the channels. When the laser cutting head is cutting, the linear module drive assembly is adapted to drive the laser cutting head to move along the magnetic material green blank transport direction and remain relatively stationary with respect to the magnetic material green blank.

[0004] Optionally, the cutting table is provided with an inclined unloading guide plate, which is located at the end of the product track away from the conveyor and is arranged at intervals with the product track. The unloading guide plate is used to guide and transport the cut magnetic material blank.

[0005] Optionally, the feeding guide plate includes a support section and an inclined section. The support section is used to support the side of the magnetic material blank away from the product track, and the inclined section is used to allow the cut magnetic material blank to slide down automatically under gravity.

[0006] Optionally, the conveyor includes a conveyor belt with a plurality of partition plates spaced apart on the conveyor belt, and the magnetic material green blank is located between two adjacent partition plates, the partition plates being used to push the magnetic material green blank to move.

[0007] Optionally, baffles are provided on both sides of the top width of the conveyor, the conveyor belt is located between the two baffles, a square tube is provided at the middle position of the width direction of the conveyor belt, the square tube is located above the conveyor belt and is arranged at intervals with the conveyor belt, and two magnetic material blanks are respectively located on both sides of the square tube on the conveyor belt.

[0008] Optionally, the linear module drive assembly includes an X linear module and a Y linear module. The Y linear module is connected to the laser cutting head to drive the laser cutting head to reciprocate along the width direction of the conveyor to cut the magnetic material blank. The X linear module is connected to the Y linear module to drive the Y linear module to move or reset the laser cutting head along the conveying direction of the magnetic material blank.

[0009] Optionally, the top of the cutting table is provided with a motor drive assembly, which is used to apply a driving force to move the magnetic blank located in the channel.

[0010] Optionally, the top of the product track has a notch that communicates with the channel. The distance from the notch to the end of the product track near the laser cutting head is less than the distance from the notch to the end of the product track near the conveyor. The motor drive assembly includes a servo motor and a roller. One side of the roller is inserted into the notch and abuts against the magnetic blank in the channel. The servo motor is used to drive the roller to rotate, thereby driving the magnetic blank in the channel to move.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] 1. The laser cutting head uses continuous high-energy laser for thermal melting processing, which can achieve non-contact, high-precision cutting, thereby improving cutting efficiency. In addition, long strip-shaped magnetic material blanks can be placed on a conveyor by a robotic arm for continuous cutting, reducing manual intervention and improving automation and processing efficiency.

[0013] 2. The conveyor can form two conveying spaces through the partition of the square tube, so that the two magnetic material green blanks do not interfere with each other when they are conveyed. In addition, the two product track bars play a positioning role, which improves the stability of the magnetic material green blanks during the conveying process.

[0014] 3. When the laser cutting head is cutting the magnetic material blank, the conveyor will not stop conveying the magnetic material blank. The linear module drive component drives the laser cutting head to move, keeping the laser cutting head and the magnetic material blank relatively stationary, so that the cutting surface is relatively flat. The conveyor will not have its lifespan affected by intermittent conveying due to frequent start and stop.

[0015] 4. The motor drive assembly and the partition plate on the conveyor apply conveying power to both ends of the magnetic material blank, improving the stability of the magnetic material blank during the conveying process. In addition, when the last magnetic material blank is cut, if the conveyor cannot provide power to the magnetic material blank inserted in the channel, the motor drive assembly can also provide power to the magnetic material blank in the channel, reducing material waste.

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-4 This application will be described in further detail.

[0022] This utility model embodiment provides a magnetic material green blank cutting device, referring to... Figure 1The magnetic material blank cutting device includes a conveyor 1, a cutting table 2, and a laser cutting mechanism 3. The cutting table 2 is located at the output end of the conveyor 1. Two product track bars 21 are spaced apart on the top of the cutting table 2, each with a channel for the magnetic material blank to pass through. The conveyor 1 is suitable for simultaneously conveying two magnetic material blanks, which are arranged at intervals along the width of the conveyor 1 and inserted into the two channels respectively. The laser cutting mechanism 3 includes a linear module drive assembly 31 and a laser cutting head 32 mounted on the top of the cutting table 2. The linear module drive assembly 31 is connected to the laser cutting head 32 to drive the laser cutting head 32 to move and cut the two magnetic material blanks exiting from the two channels. When the laser cutting head 32 is cutting, the linear module drive assembly 31 is suitable for driving the laser cutting head 32 to move along the conveying direction of the magnetic material blank and maintaining relative stillness with the magnetic material blank, resulting in a relatively flat cutting surface. This prevents the conveyor 1 from experiencing intermittent conveying due to frequent starts and stops, thus extending its lifespan.

[0023] Reference Figure 2 and Figure 3 The conveyor 1 includes a conveyor belt 11, a frame 12, and a drive motor. Both the conveyor belt 11 and the drive motor are connected to the frame 12, and the drive motor works in conjunction with the conveyor belt 11 to drive its rotation. Robotic arms (not shown in the figure) are provided on both sides of the width of the frame 12. These robotic arms can pick up stacked magnetic material green strips and place them on the conveyor belt 11. In another embodiment, the magnetic material green strips can be placed on the conveyor belt 11 manually. Multiple partition plates 13 are spaced apart on the conveyor belt 11. The magnetic material green strips are located between adjacent partition plates 13, and during the operation of the conveyor belt 11, the partition plates 13 push the magnetic material green strips to move.

[0024] The conveyor belt 11 drives the magnetic material green strip to move along the length of the frame 12. Both sides of the top width of the frame 12 are fixed with baffles by bolts. The conveyor belt 11 is located between the two baffles. The baffles can limit the magnetic material green strip and prevent it from falling off the conveyor 1 during the conveying process.

[0025] Reference Figure 2 and Figure 3 A square tube 14 is positioned at the midpoint of the width of the conveyor belt 11. The square tube 14 is connected to a baffle, and its length is the same as the conveying distance of the conveyor belt 11, thus dividing the conveyor belt 11 into two conveying spaces. Each partition plate 13 is also divided into two. Two magnetic material green strips are located in the two conveying spaces respectively (i.e., the two magnetic material green strips are located on opposite sides of the square tube 14 on the conveyor belt 11), with their sides abutting against the square tube 14 and the corresponding baffle, thereby achieving stable directional movement. A gap exists between the square tube 14 and the top of the conveyor belt 11, preventing the square tube 14 from contacting the conveyor belt 11 and causing friction, which would affect the service life of the conveyor belt 11.

[0026] Multiple bolts are welded to the top of the square tube 14, and the bolts are spaced apart along the length of the square tube 14. Each bolt at the top of the square tube 14 is fitted with a connecting plate, and each bolt is threaded with a nut. The nuts and bolts cooperate to fix the connecting plate to the square tube 14. The two ends of the connecting plate are fixed to two baffles by bolts, thereby fixing the square tube 14 to the two baffles. The distance between two adjacent connecting plates is greater than the length between two adjacent partition plates 13, thus providing sufficient space for the placement of the magnetic material blank.

[0027] Reference Figure 2 and Figure 3 The product track 21 is fixedly connected to the cutting table 2 by bolts, which are located at the bottom of the cutting table 2 surface. A channel runs through the product track 21 along the conveying direction of the magnetic material blank. A motor drive assembly 15 is provided on the top of the cutting table 2, which applies a driving force to the magnetic material blank located within the channel. The motor drive assembly 15 and the partition plate 13 on the conveyor 1 apply conveying power to both ends of the magnetic material blank, improving the stability of the magnetic material blank during conveying.

[0028] Combination Figure 2 Reference Figure 3 and Figure 4 Each product track 21 has a notch at its top, which connects to the channel. The distance from the notch to the end of the product track 21 near the laser cutting head 32 is less than the distance from the notch to the end of the product track 21 near the conveyor 1. The motor drive assembly 15 includes a servo motor 16 and rollers 17. A motor plate is bolted to the top of the cutting table 2, and the servo motor 16 is bolted to the motor plate. A rotating shaft is connected to and rotates synchronously on the motor shaft of the servo motor 16. A bearing support is bolted to the top of the cutting table 2, and the end of the rotating shaft away from the motor is inserted into the bearing support and rotatably connected to it. Since there are two product tracks 21, there are also two rollers 17. The two rollers 17 are fitted onto the rotating shaft and rotate synchronously with it. Both rollers 17 are rubber wheels, and each roller 17 has a retaining spring (not shown in the figure) at both ends of its axial direction. The roller 17 shaft has a retaining spring groove for the retaining spring to engage, preventing the roller 17 from moving axially along the rotating shaft. One side of the roller 17 is inserted into the notch and pressed against the magnetic blank in the channel. After the servo motor 16 rotates, it drives the roller 17 to rotate, thereby moving the magnetic blank in the channel. The rubber roller 17 can increase the friction on the magnetic blank, drive the magnetic blank to move, and is less likely to cause scratches on the surface of the magnetic blank.

[0029] Combination Figure 2 Reference Figure 3 and Figure 4The linear module drive assembly 31 includes an X-line module 33 (prior art, with a movable sliding part) and a Y-line module 34 (prior art, with a movable sliding part). The X-line module 33 is fixedly connected to the cutting table 2 by bolts, and the movement direction of the sliding part on the X-line module 33 is consistent with the conveying direction of the conveyor 1; the movement direction of the sliding part on the Y-line module 34 is the width direction of the conveyor 1. A connecting frame is fixedly mounted on the sliding part of the Y-line module 34 by bolts, and the laser cutting head 32 is fixedly connected to the connecting frame by bolts, so that the laser cutting head 32 reciprocates along the width direction of the conveyor 1 to cut two magnetic material blanks. One side of the Y-line module 34 is fixedly connected to the sliding part of the X-line module 33 by bolts, driving the Y-line module 34 to move or reset the laser cutting head 32 along the conveying direction of the magnetic material blanks, thereby keeping the laser cutting head 32 and the magnetic material blanks relatively stationary during the movement.

[0030] A sliding support frame is bolted to the top of the cutting table 2. The sliding support frame is located at the end of the Y-linear module 34 furthest from the X-linear module 33. A linear guide rail is bolted to the sliding support frame, and a slider slides along the linear guide rail. The slider is fixedly connected to the Y-linear module 34 by bolts. This serves two purposes: firstly, it supports the other end of the Y-linear module 34; secondly, it improves the smoothness of the Y-linear module 34 during sliding.

[0031] A bracket (not shown in the figure) is fixed to the top of the cutting table 2 by bolts. A light sensor is installed on the bracket by bolts. When the magnetic blank moves to the light sensor, it will block the light, and then the control system controls the laser cutting head 32 to start cutting. The control system also controls the linear module drive component 31 to operate and controls the laser cutting head 32 to move.

[0032] Combination Figure 2 Reference Figure 3 and Figure 4 The top of the cutting table 2 has multiple support columns welded at intervals, and a material guide plate 18 is fixedly installed on the support columns. The material guide plate 18 is located at the end of the product track 21 away from the conveyor 1, and is arranged at intervals with the laser cutting head 32. After the laser cutting head 32 has cut the two magnetic blanks, it will not affect the material guide plate 18. The material guide plate 18 is used to guide and transport the cut magnetic blanks.

[0033] The unloading guide plate 18 includes a support section and an inclined section. The height of the inclined section near the laser cutting head 32 is higher than the height of the other end. The support section is located at the end of the inclined section near the laser cutting head 32. The support section is horizontal and is used to support the side of the magnetic material blank that protrudes from the channel and is away from the product track 21, thereby improving the stability of the magnetic material blank during cutting. A collection basket is provided at the bottom of the inclined section. The cut magnetic material blank will automatically slide into the collection basket under gravity through the inclined section.

[0034] The implementation principle of the magnetic material green blank cutting device in this application embodiment is as follows: The magnetic material green blank is conveyed to the channel of the product track 21 by the conveyor 1. After the magnetic material green blank passes through the channel and moves to the light sensor, it blocks the light. Then, the control system controls the laser cutting head 32 to start cutting, and the control system controls the linear module drive component 31 to operate, controlling the movement of the laser cutting head 32. When the laser cutting head 32 is cutting the magnetic material green blank, the conveyor 1 does not stop conveying the magnetic material green blank, while the linear module drive component 31 drives the laser cutting head 32 to move, so that the laser cutting head 32 and the magnetic material green blank remain relatively stationary, resulting in a relatively flat cutting surface and the ability to cut two magnetic material green blanks at a time. The cut magnetic material green blank will automatically slide into the collection basket under gravity through the inclined section.
