Description

Technical Field

[0001] This utility model belongs to the field of neodymium iron boron sheet processing technology, and specifically relates to a clamping device for cutting neodymium iron boron sheets. Background Technology

[0002] When laser-cutting neodymium iron boron, due to the small size of the product, in order to prevent the product from falling after cutting and the material from breaking during the cutting process, a 1.5mm border needs to be left on the top, bottom, left, and right sides of the material to increase its strength.

[0003] To prevent displacement during product cutting and subsequent dimensional defects, the material sheet needs to be clamped. Existing technologies employ two clamping methods: one involves pressing the material sheet down from both sides. Once the material is in place, a pressure cylinder controls the movement of the pressure plates on both sides, causing them to clamp downwards and press against the left and right sides of the material sheet, thus fixing it in place.

[0004] Another method is left and right clamping. When the product reaches the corresponding cutting position, the left cylinder pushes the pressing device to the right, thereby clamping the product left and right. This method requires a high clamping force. If the force is too large when cutting thin slices, the slices will break in the middle. If the force is too small, the slices will not be clamped tightly and will slip, resulting in the product dimensions being unqualified.

[0005] In order to achieve clamping and prevent material loss during cutting, both of the above existing technologies require a border of about 1.5mm to be left before cutting, resulting in low material utilization. Utility Model Content

[0006] In view of this, the purpose of this utility model is to address the shortcomings of the prior art by providing a clamping device for cutting NdFeB sheets, which uses vacuum adsorption to fix the sheet, so that even if the frame width is reduced, the sheet will not fall off during processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A clamping device for cutting NdFeB thin sheets includes a drive assembly, a rotating shaft, and a suction cup fixture. The drive assembly drives the rotating shaft to rotate, the rotating shaft is connected to the suction cup fixture, and the drive assembly can drive the suction cup fixture to rotate around the rotating shaft. The suction cup fixture includes a housing connected to a negative pressure pipeline and multiple suction heads disposed on the housing, with the suction ports of the suction heads being on the same horizontal plane.

[0009] To better realize this utility model, the above structure is further optimized by setting two suction cup fixtures, which are symmetrical about the axis of rotation.

[0010] To better realize this utility model, the above structure is further optimized. One end of the rotating shaft is connected to the drive component, and the other end is connected to a bearing, which is mounted on a bearing seat.

[0011] To better realize this utility model, the above structure is further optimized, and the driving component is a motor.

[0012] To better realize this utility model, the above structure is further optimized, and the motor is a servo motor.

[0013] To better realize this utility model, the above structure is further optimized by setting the drive component on the fixed base.

[0014] To better realize this utility model, the above structure is further optimized, and the bearing seat is set on the fixed seat two.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This utility model provides a method for cutting NdFeB sheets that abandons mechanical clamping and uses vacuum adsorption. Multiple micro vacuum heads are used to first adsorb the sheet before cutting. During the adsorption process, the sheet does not move. Because vacuum adsorption uses multiple micro vacuum heads, there are more contact points and more support points, which indirectly increases the strength of the sheet. Even if the frame width is reduced, the product will not fall off during cutting. By using vacuum adsorption, the conventional left-right or top-bottom clamping positions of the product are avoided, thereby reducing the requirements for frame width. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Please refer to Figures 1-3The clamping device for cutting NdFeB sheets provided in this application includes a drive assembly 1, a rotating shaft 2, and a suction cup fixture 3. The drive assembly 1 drives the rotating shaft 2 to rotate. In this embodiment, the drive assembly 1 is preferably a servo motor, which can precisely control the rotation angle and improve control accuracy. The rotating shaft 2 is connected to the suction cup fixture 3, and the drive assembly 1 can drive the suction cup fixture 3 to rotate around the rotating shaft 2. The suction cup fixture 3 includes a housing 301 connected to a negative pressure pipeline and multiple suction heads 302 disposed on the housing 301. The suction ports of the suction heads 302 are on the same horizontal plane. By adopting a vacuum adsorption function, the conventional left-right or up-down clamping positions of the product are avoided, thereby achieving the effect of reducing the requirement for the width of the frame. The frame width can be reduced from 1.5mm to 0.2mm, improving material utilization and reducing processing costs. Moreover, the multiple suction heads 302 provide more support points, indirectly increasing the strength of the sheet. Even with the reduced frame width, the part 10 will not fall off during cutting.

[0027] In this embodiment, in order to better realize the present invention, the above structure is further optimized. Two suction cup fixtures 3 are provided and are symmetrical about the axis of the rotation shaft 2. When one of the suction cup fixtures 3 clamps the part 10 to be processed, the suction cup fixture 3 on the other side rotates 180°. By turning off the vacuum adsorption function on that side, the part 10 falls down smoothly. The two suction cup fixtures 3 process in cycles, which reduces the cutting waiting time and improves the work efficiency.

[0028] One end of the rotating shaft 2 is connected to the drive assembly 1, and the other end is connected to a bearing. The bearing is mounted on a bearing housing 4, ensuring reliable support at both ends of the rotating shaft 2 and reducing its circular runout. The drive assembly 1 is mounted on a fixed base 5. The bearing housing 4 is mounted on a fixed base 6. By fixing the machine body, the stability of the device during operation is improved.

[0029] Working principle:

[0030] First, the pusher mechanism pushes part 10 along the feeding track 11 to the cutting position on the suction cup fixture 3. The bottom of part 10 is attached to the suction port of suction head 302. Then, vacuum adsorption is started, and part 10 is tightly fixed on the suction cup fixture through the negative pressure pipeline. Then, laser processing is performed. After processing is completed, the motor is controlled to rotate 180° so that the cut piece reaches the unloading position (receiving port 12). Then, the vacuum adsorption function is turned off, and the product falls from the receiving port 12. Another part 10 can be processed at the same time, and so on.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
