Description
Technical Field
[0001] This utility model relates to the field of neodymium iron boron (NdFeB) preform production technology, and in particular to a NdFeB preform feeding device. Background Technology
[0002] In the production process of NdFeB permanent magnet materials, the blank feeding process is crucial. Traditional NdFeB blank feeding methods mostly rely on manual handling or simple mechanical assistance. Manual handling is not only labor-intensive, requiring workers to frequently travel between the storage and pressing areas, resulting in extremely high labor intensity, but also has very low feeding efficiency. During handling, due to the instability of manual operation, the pressed blanks are prone to displacement or falling. NdFeB pressed blanks are hard and brittle; once dropped or impacted, surface defects such as cracks and wear may occur, severely affecting their internal magnetic properties, leading to decreased product quality, increased scrap rate, and consequently increased production costs. In the clamping stage, previous equipment used coarse clamping actions lacking precise control. Inappropriate clamping force often resulted in either unstable clamping causing the pressed blank to fall during transportation, or excessive clamping damaging the surface of the pressed blank, affecting product quality. Because the clamping position and force could not be precisely controlled, it was difficult to ensure that the pressed blank accurately fell into the pressing groove of the lower mold, resulting in uneven force on the pressed blank during the pressing process, leading to quality problems such as dimensional deviations and inconsistent density, reducing the product qualification rate. Therefore, we propose a NdFeB pressed blank feeding device to solve this problem. Utility Model Content
[0003] The purpose of this invention is to provide a neodymium iron boron (NdFeB) preform feeding device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A neodymium iron boron (NdFeB) blank feeding device includes: a base, a movable component disposed inside the base, the movable component including: a threaded rod, a threaded plate threadedly connected to the outer side of the threaded rod, a connecting block fixedly mounted on the top of the threaded plate, a placement platform fixedly mounted on the top of the connecting block, an arc-shaped clamping block fixedly mounted on the top of the placement platform, a NdFeB blank movably abutting against one side of the arc-shaped clamping block, a short plate fixedly mounted on one side of the placement platform, an electric push rod fixedly mounted on one side of the short plate, a positioning clamping plate fixedly mounted on the output end of the electric push rod, and the positioning clamping plate and the NdFeB blank... The blank is movable and abuts against the base. A lead screw is provided on one side of the base, and a threaded block is provided on the outer side of the lead screw. A gripper assembly is provided on one side of the threaded block. The gripper assembly includes: a connecting plate, a fixing plate on one side of the connecting plate, a cylinder two fixedly installed on one side of the fixing plate, a moving block fixedly installed at the output end of the cylinder two, multiple sets of connecting rods hinged to both sides of the moving block, and the same set of clamping rods hinged between the multiple sets of connecting rods on the same side. An arc-shaped clamping plate is fixedly installed on the side of the two sets of clamping rods that are close to each other. A lower mold is provided on one side of the base, and an upper mold is provided on the top of the lower mold.
[0006] Preferably, the threaded rod is rotatably mounted on the inner walls of both sides of the base, and a second motor is fixedly mounted on one side of the base, with the output shaft of the second motor fixedly connected to the threaded rod.
[0007] Preferably, two sets of mounting brackets are provided on one side of the base, and the lead screw is rotatably installed inside the two sets of mounting brackets. A motor is fixedly installed on one side of the right mounting bracket, and the output shaft of the motor is fixedly connected to the lead screw.
[0008] Preferably, a bracket is fixedly installed on the top of the lower mold, and a cylinder is fixedly installed on the top of the bracket. The output end of the cylinder is fixedly connected to the upper mold. A pressure groove is opened inside the lower mold, and the upper mold is adapted to the pressure groove.
[0009] Preferably, two sets of electric push rods are fixedly installed on the top of the connecting plate, and the output ends of the two sets of electric push rods are fixedly connected to the fixed plate. Two sets of guide plates are fixedly installed on one side of the fixed plate, and the two sets of clamping rods are slidably installed on the outer side of the corresponding guide plates.
[0010] Preferably, a limiting rod is slidably installed inside the threaded block, and the two ends of the limiting rod are respectively fixedly connected to the corresponding mounting bracket. Two sets of guide rods are slidably installed inside the threaded plate, and the two ends of the two sets of guide rods are respectively fixedly connected to the inner walls of both sides of the base. A sliding groove is provided on the top of the base, and the connecting block is slidably installed inside the sliding groove.
[0011] In this invention, a neodymium iron boron (NdFeB) blank feeding device is provided, comprising a moving component, an electric push rod, and a positioning clamp. By activating the electric push rod on one side of the short plate, the output end of the electric push rod pushes the positioning clamp towards the NdFeB blank until the positioning clamp comes into contact with the blank, thus fixing the blank on the placement table. Then, a second motor is activated, and its output shaft drives a threaded rod to rotate. As the threaded rod rotates, a threaded plate moves along the axial direction of the threaded rod, and the connecting block fixedly installed on the top of the threaded plate moves accordingly. This causes the placement table to slide within a groove on the top of the base, allowing the NdFeB blank to be delivered to one side of the base. This enables the blank to be transported quickly and stably to a designated location, saving labor costs, improving overall production efficiency, and effectively preventing the blank from shifting or falling during transportation. This ensures the integrity and stability of the blank during movement, providing a guarantee for subsequent precise feeding.
[0012] In this invention, a neodymium iron boron (NdFeB) blank feeding device is provided, comprising a gripper assembly, a lead screw, a threaded block, an upper mold, a lower mold, and a cylinder 1. A second cylinder drives the output end of the second cylinder, which in turn moves a moving block. Multiple sets of connecting rods hinged on both sides of the moving block move accordingly. Due to the hinged relationship between the connecting rods, multiple sets of connecting rods on the same side drive the same set of clamping rods to move inwards, causing the arc-shaped clamping plate on one side of the two sets of clamping rods to clamp the NdFeB blank. The reverse movement of the second cylinder is then initiated, causing the moving block to move in the opposite direction. Through the connecting rods, the clamping rods open outwards, and the arc-shaped clamping plate releases the NdFeB blank, allowing it to fall into the pressing groove at the top of the lower mold. This device allows for precise control of the gripping action, preventing the blank from falling or shifting position due to unstable gripping. It ensures the stability of the blank during transportation, protects the quality of the blank from damage, and guarantees that the blank falls accurately into the pressing groove of the lower mold, providing a foundation for subsequent precise pressing. This achieves continuous and efficient feeding operations. Attached Figure Description

[0021] In this embodiment, a bracket 3 is fixedly installed on the top of the lower mold 2, and a cylinder 15 is fixedly installed on the top of the bracket 3. The output end of the cylinder 15 is fixedly connected to the upper mold 4.

[0022] In this embodiment, during use, the NdFeB blank 10 is placed on the placement platform 7, with one side of it movably abutting against the arc-shaped locking block. The electric push rod 9 on one side of the short plate is activated. The output end of the electric push rod 9 pushes the positioning clamp 8 towards the NdFeB blank 10 until the positioning clamp 8 movably abuts against the blank, thus fixing the blank on the placement platform 7 and preventing it from shifting or falling during transportation. The second motor 601 is then activated. The output shaft of the second motor 601 drives the threaded rod 602 to rotate. When the threaded rod 602 rotates, the threaded plate 60... 3 will move along the axial direction of the threaded rod 602, and the connecting block 604 fixedly installed on the top of the threaded plate 603 will move accordingly, thereby driving the placement platform 7 to slide in the groove on the top of the base 1, so that the NdFeB blank 10 can be sent to one side of the base 1.

The output end of the cylinder 504 pushes the moving block 506 to move. The multiple sets of connecting rods 507 hinged on both sides of the moving block 506 move accordingly. Due to the hinge relationship between the connecting rods 507, the multiple sets of connecting rods 507 on the same side drive the same set of clamping rods 505 to move inward, so that the arc-shaped clamping plate 508 on one side of the two sets of clamping rods 505 clamps the NdFeB blank 10. The motor 13 is activated again, so that the lead screw... 11 rotates, causing the gripper assembly 5, which has gripped the blank, to move above the lower mold 2.
