At the same time, the advantage of high energy density makes NdFeB permanent magnet material widely used in modern industry and electronic technology, making it possible to miniaturize, lighten and thin the equipment such as instruments, electroacoustic motors, magnetic separation and magnetization.

[0003] At present, NdFeB trapezoidal products are used in fine equipment such as mobile phone receivers. In the process of preparing NdFeB trapezoidal products, the magnetized trapezoidal products need to be combined into parallel plates. However, since the height of the trapezoidal product is 1.5mm, the thickness is 1.2mm, the bottom is 3.41mm, and the bottom is generally 2.3mm. Because its structure is very small, the magnetized trapezoidal products are adsorbed and arranged in a disorderly manner due to the effect of magnetism. Therefore, workers are required to smooth the materials afterwards. After the trapezoidal products are magnetized, manual smoothing is very troublesome and inefficient. Summary of the invention

The longitudinal rubbing platform 901 is fixed at the outlet of the material pulling conveying mechanism 6. The upper end of the longitudinal rubbing platform 901 is respectively provided with a downward pressing contact plate 902 and a longitudinal rubbing press plate 903. The downward pressing contact plate 902 is connected to the output end of the downward pressing cylinder 904, and the output end of the downward pressing cylinder 904 is fixed on the machine table 1 through the downward pressing bracket 908. The longitudinal rubbing press plate 903 is connected to the output end of the longitudinal rubbing side moving cylinder 906. The cylinder seat of the longitudinal rubbing side moving cylinder 906 is connected to the output end of the longitudinal rubbing downward moving cylinder 905. The cylinder seat of the longitudinal rubbing downward moving cylinder 905 is connected to the machine table 1 through the longitudinal rubbing bracket 907.

[0047] When the above-mentioned downward pressing cylinder 904 is started, the downward pressing cylinder 904 moves the downward pressing contact plate 902 onto the longitudinal rubbing platform 901. The longitudinal rubbing downward moving cylinder 905 and the longitudinal rubbing side moving cylinder 906 act, and finally the longitudinal rubbing press plate 903 is pushed towards the lower side for rubbing and leveling.

[0048] The feeding driving wheel 203 of the above-mentioned feeding conveying mechanism 2 and the magnetizing driving wheel 306 in the magnetizing mechanism 3 can be driven by the driving motor of the same driving mechanism.

[0049] When the above solution is in use, the inlet position of the feeding conveyor mechanism 2 corresponds to the outlet position of the vibrating feeding tray. Small trapezoidal products arranged in the same direction coming out of the outlet of the vibrating feeding tray enter the feeding conveyor belt 201 of the feeding conveyor mechanism 2. The rotation speed of the feeding conveyor belt 201 is greater than the discharging speed of the discharging port of the vibrating feeding tray. Therefore, the trapezoidal products enter the feeding conveyor belt 201 at intervals and in parallel. The trapezoidal products enter between the magnetizing and positioning conveyor belt 301 and the feeding conveyor belt 201, and the trapezoidal products are squeezed and positioned by the magnetizing and positioning conveyor belt 301 and the feeding conveyor belt 201. The trapezoidal products are driven by the magnetizing and positioning conveyor belt 301 and the feeding conveyor belt 201 to the positions of the upper magnetizing body 303 and the lower magnetizing body 304. The upper magnetizing body 303 is set as the N pole, and the lower magnetizing body 304 is set as the S pole. Both are weak magnetic magnets. When the trapezoidal products pass through between the upper magnetizing body 303 and the lower magnetizing body 304, they are magnetized, and then the trapezoidal products are weakly magnetic. The magnetized trapezoidal products enter the laser detection mechanism 4. The products in the material conduction gap between the adjacent detection guide plates of the magnetized trapezoidal products move under the drive of the feeding conveyor belt. The magnetized trapezoidal products enter the material conduction gap through between the two horn-shaped detection guide plates. The magnetized trapezoidal products are detected by the laser detector 404 near the material outlet position. When the trapezoidal products are detected by the laser detector 404 far from the material outlet, it means that the trapezoidal products between the two laser detectors 404 attract each other side by side and the trapezoidal products have entered the transition table 5 and stay at the end of the material outlet of the transition table 5. The detection frequency of the laser detector 404 far from the material outlet is not sensitive and can only be detected when there is a trapezoidal product stopping at the position of this laser detector 404. Therefore, at this time, a trapezoidal product splicing section is formed. After the laser detector 404 far from the material outlet detects and forms a trapezoidal product splicing section, the drive mechanism of the driving pulling main wheel 602 in the pulling conveyor mechanism 6 is started. This drive mechanism is a stepping motor, and the stepping motor drives the pulling conveyor belt 601 to move. At the same time, the products forming the trapezoidal product splicing section are moved to the position of the horizontal rubbing and squeezing mechanism 7. One side of the trapezoidal product splicing section contacts the side surface of the side pressing plate 610. The squeezing cylinder 704 in the horizontal rubbing and squeezing mechanism 7 acts to drive the squeezing plate 702 to squeeze the side surface of the trapezoidal product splicing section. At the same time, the pressing and rubbing cylinder 703 drives the pressing and rubbing plate 701 to move downwards and rubs in the direction of the material movement, so as to flatten its side surface and upper end surface. The rubbed trapezoidal product splicing section is driven by the stepping motor to move the pulling conveyor belt 601 to the lower part of the guiding and flattening mechanism 8. The length of the trapezoidal product splicing section is exactly the diameter of the guiding and flattening platform 802 of the guiding and flattening mechanism 8. The guiding motor 801 drives the guiding and flattening platform 802 to rotate, so as to rotate and guide the twisted trapezoidal product splicing section. After the guiding is completed, the stepping motor continues to drive the pulling conveyor belt 601 to move, so as to move the trapezoidal product splicing section out of the pulling conveyor belt 601 and enter the longitudinal rubbing and flattening machine at the same time.The lower pressing air cylinder 904 in the longitudinal rubbing and flattening mechanism 9 drives the lower pressing contact plate 902 to move downward. The side surface of the lower pressing contact plate 902 contacts the side surface of the trapezoidal product splicing section. The longitudinal rubbing downward air cylinder 905 and the longitudinal rubbing sideward air cylinder 906 act simultaneously, and the longitudinal rubbing flat plate 903 rubs and flattens the trapezoidal product splicing section.

[0050] Before the stepping motor is in the working state, the pressing plate air cylinder 611 drives the side pressing plate 610 to move downward, compacting the gap between the material pulling conveyor belt 601 and the side pressing plate 610, so as to prevent the trapezoidal product splicing section from being squeezed into the gap between the material pulling conveyor belt 601 and the side pressing plate 610 when the horizontal rubbing and squeezing mechanism 7 and the guiding and flattening mechanism 8 are working. When the stepping motor is working, the pressing plate drives the side pressing plate 610 to move upward, opening the gap between the material pulling conveyor belt 601 and the side pressing plate 610 to facilitate the movement of the material pulling conveyor belt 601. In order to improve the working efficiency, generally two sets of neodymium iron boron trapezoidal product feeding machines are arranged in parallel on the machine table 1. Due to the adoption of the above structure, the present invention has the advantages of simple structure, good feeding effect, high feeding efficiency, and manpower saving.
