Description

Technical Field

[0001] This invention relates to the field of NdFeB trapezoidal product material processing technology, specifically a NdFeB trapezoidal product material processing machine with simple structure, good material processing effect, high material processing efficiency, and labor saving. Background Technology

[0002] As is well known, neodymium iron boron (NdFeB) is a rare-earth permanent magnet material with extremely high magnetic energy product and coercivity. At the same time, its high energy density has enabled NdFeB permanent magnet materials to be widely used in modern industry and electronic technology, making it possible to miniaturize, lighten, and thin the instruments, electroacoustic motors, magnetic separation and magnetization equipment.

[0003] Currently, NdFeB trapezoidal products are used in precision equipment such as mobile phone earpieces. In the manufacturing process of NdFeB trapezoidal products, the magnetized trapezoidal products need to be combined into parallel plates. However, because the height of the trapezoidal products is 1.5mm, the thickness is 1.2mm, and the bottom is 3.41mm (most commonly 2.3mm), due to their very small structure, the magnetized trapezoidal products are randomly attracted and arranged due to the magnetic effect. Therefore, workers are required to straighten the materials afterward. Since manual straightening of the magnetized trapezoidal products is very troublesome and inefficient, it is very difficult. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a neodymium iron boron trapezoidal product winding machine with simple structure, good winding effect, high winding efficiency, and labor saving.

[0051] In the above scheme, the inlet position of the feeding conveyor 2 corresponds to the outlet position of the vibrating feeding plate. Small, trapezoidal products arranged in the same direction exiting the vibrating feeding plate enter the feeding conveyor belt 201 of the feeding conveyor 2. The rotational speed of the feeding conveyor belt 201 is greater than the discharge speed of the vibrating feeding plate. Therefore, the trapezoidal products enter the feeding conveyor belt 201 in a spaced-apart parallel manner. The trapezoidal products enter between the magnetic positioning conveyor belt 301 and the feeding conveyor belt 201. The trapezoidal products are squeezed and positioned by the magnetic positioning conveyor belt 301 and the feeding conveyor belt 201. The trapezoidal products are driven by the magnetic positioning conveyor belt 301 and the feeding conveyor belt 201 to the positions of the upper magnet 303 and the lower magnet 304. The upper magnet 303 is set as N. The upper magnet 303 and the lower magnet 304 are both weakly magnetic. When the trapezoidal product passes between the upper magnet 303 and the lower magnet 304, it is magnetized, thus acquiring a weak magnetic charge. The magnetized trapezoidal product then enters the laser detection mechanism 4. Within the material passage gap between adjacent detection guide plates, the magnetized trapezoidal product is moved by the feeding conveyor belt. It passes between the two trumpet-shaped detection guide plates and enters the material passage gap. The magnetized trapezoidal product is detected by the laser detector 404 near the material outlet. When the trapezoidal product is detected by the laser detector 404 away from the material outlet, it indicates that the trapezoidal products between the two laser detectors 404 are mutually attracted and trapezoidal. The product has entered the transition table 5 and is stationary at the end of the material outlet of the transition table 5. The detection frequency of the laser detector 404, which is far from the material outlet, is not sensitive. It can only be detected when a trapezoidal product stops at the position of the laser detector 404. Therefore, a trapezoidal product splicing segment is formed at this time. After the laser detector 404, which is far from the material outlet, detects the formation of a trapezoidal product splicing segment, the drive mechanism of the drive pull wheel 602 in the pulling conveyor mechanism 6 is started. This drive mechanism is a stepper motor. The stepper motor drives the pulling conveyor belt 601 to move, and at the same time moves the product that has formed the trapezoidal product splicing segment to the position of the horizontal rubbing and extrusion mechanism 7. One side of the trapezoidal product splicing segment contacts the side of the side pressure plate 610. The horizontal rubbing and extrusion mechanism 7... The extrusion cylinder 704 in the middle is activated, driving the extrusion plate 702 to extrude the side of the trapezoidal product splice section. At the same time, the pressure-rubbing cylinder 703 drives the pressure-rubbing plate 701 to move downward and rub in the direction of material movement, thereby achieving flatness of its side and top surfaces. The rubbed trapezoidal product splice section is moved by the stepper motor-driven material pulling conveyor belt 601 to below the leveling mechanism 8. The length of the trapezoidal product splice section is exactly the diameter of the leveling pressure table 802 of the leveling mechanism 8. The leveling motor 801 drives the leveling pressure table 802 to rotate, thereby rotating and leveling the twisted trapezoidal product splice section. After leveling is completed, the stepper motor continues to drive the material pulling conveyor belt 601 to move, thereby moving the trapezoidal product splice section out of the material pulling conveyor belt 601 and into the longitudinal rubbing and flattening machine.In the longitudinal rubbing and flattening mechanism 9, the downward pressing cylinder 904 drives the downward pressing contact plate 902 to move downward. The side of the downward pressing contact plate 902 contacts the side of the trapezoidal product splicing section. Simultaneously, the longitudinal rubbing downward moving cylinder 905 and the longitudinal rubbing side moving cylinder 906 act, and the longitudinal rubbing pressing plate 903 rubs and smooths the trapezoidal product splicing section.

[0052] Before the stepper motor starts working, the pressure plate cylinder 611 drives the side pressure plate 610 to move downward, compacting the gap between the material conveyor belt 601 and the side pressure plate 610. This prevents the trapezoidal product splicing section from being squeezed into the gap between the material conveyor belt 601 and the side pressure plate 610 when the horizontal rubbing and extrusion mechanism 7 and the leveling mechanism 8 are working. When the stepper motor starts working, the pressure plate drives the side pressure plate 610 to move upward, opening the gap between the material conveyor belt 601 and the side pressure plate 610, facilitating the movement of the material conveyor belt 601. To increase working efficiency, two sets of NdFeB trapezoidal product straightening machines are generally installed in parallel on the machine base 1. Due to the above structure, this invention has the advantages of simple structure, good straightening effect, high straightening efficiency, and saving manpower.
