[0055] In a preferred embodiment, Figure 2 As shown, the posture adjustment unit includes a rotating motor 130 and a clamping cylinder 131 fixedly arranged on the rotating output end of the rotating motor 130 .

[0056] The clamping cylinder 131 can clamp the material block 120 at the adjustment station, and the rotating motor 130 can drive the clamping cylinder 131 to rotate to adjust the direction in which the clamping cylinder 131 clamps the material block 120 .

[0057] In a preferred embodiment, Figure 2 As shown, two groups of rotating motors 130 and clamping cylinders 131 are provided, and the two groups of rotating motors 130 and clamping cylinders 131 are symmetrically arranged about the adjustment station.

The second camera 141 is used to inspect the appearance and size of the material block 120 on the first rotating table 140.

[0060] In a preferred embodiment, Figure 2 As shown, the detection unit further includes a second rotating stage 150, a scanning sensor 151 and a detection transfer component.

[0061] Among them, the detection transfer component can transfer the material block 120 on the first rotating table 140 to the second rotating table 150, and the second rotating table 150 can drive the material block 120 at the corresponding position to rotate in the horizontal direction. The scanning sensor 151 is specifically configured as a three-dimensional line scanning laser sensor and is used to perform surface flatness inspection on the material block 120 on the second rotating table 150.

[0062] In a preferred embodiment, Figure 2 As shown, the detection unit further includes a weighing device 160 .

[0063] Among them, the detection transfer component can transfer the material block 120 on the second rotating table 150 to the weighing device 160, the weighing device 160 is used to weigh the material block 120 at the corresponding position, and the inkjet printer 161 can perform inkjet processing on the material block 120 at the corresponding position of the weighing device 160.

[0068] In a preferred embodiment, Figure 2As shown, a plurality of transfer clamps 172 are provided on the slide 171 .

[0069] It can be understood that since there are multiple transfer clamps 172, when the first turntable 140, the second turntable 150, and the weighing device 160 simultaneously perform inspections on different material blocks 120, the transfer clamps 172 at the corresponding positions can synchronously grab the material blocks 120 at the corresponding inspection stations, thereby further shortening the sorting cycle of the material blocks 120.

The stacking unit can sort the material blocks 120 that pass the inspection to the qualified product unloading station, and sort the material blocks 120 that fail the inspection to the unqualified product unloading station.

[0073] like Figure 3 As shown, the embodiment of the present application provides a method for sorting NdFeB magnet blocks, which is applicable to the sorting device 100 in the above embodiment, including:

[0074] Step S1, obtaining the posture state information, first appearance information and distribution information of the material block in the graphite box, and formulating the material taking order of the material block based on the distribution information;

[0075] Step S2, judging whether the first appearance information of the material block is qualified, taking the material block whose first appearance information is qualified, and unloading the material block whose first appearance information is unqualified;

[0076] Step S3, judging whether the posture state information of the material block is qualified, transferring the material block with qualified posture state information to the first inspection station, performing posture correction on the material block with unqualified posture state information, and transferring the material block after posture correction to the first inspection station;

[0077] Step S4, obtaining the second appearance information and size information of the material block at the first inspection station, transferring the material block with qualified second appearance information and size information to the second inspection station, and performing material removal for the material block with unqualified second appearance information and size information;

[0082] Among them, the first camera 112 mainly performs an appearance inspection on the top of the material block 120, that is, the first appearance information is specifically the appearance condition of the top of the material block 120. When the appearance condition of the top of the material block 120 is unqualified, material unloading is executed, and when the appearance condition of the top of the material block 120 is qualified, material removal is executed.

[0083] In a preferred embodiment, in step S3, the gripping robot 110 transfers the material block 120 with qualified posture state information to the inspection station (first inspection station) of the first rotating table 140 through the material picking clamp 111, and transfers the material block 120 with unqualified posture state information to the adjustment station of the posture adjustment unit. When performing posture adjustment, the material picking clamp 111 releases the material block 120, the clamping cylinder 131 clamps the material block 120, and the rotating motor 130 drives the clamping cylinder 131 to rotate, and the material block 120 at the corresponding position is straightened based on the posture state information. When the posture adjustment of the material block 120 is completed, the gripping robot 110 again transfers the material block 120 at the adjustment station to the inspection station (first inspection station) of the first rotating table 140 through the material picking clamp 111.

For the material blocks 120 with qualified circumferential appearance and size, they are transferred to the inspection station (second inspection station) of the second rotating table 150 through the detection transfer component, while the material blocks 120 with unqualified circumferential appearance and size are unloaded.

[0085] In a preferred embodiment, in step S5, the second rotating table 150 drives the material block 120 on the second inspection station to rotate on a horizontal plane, and the scanning sensor 151 checks the surface depressions and protrusions (surface flatness information) of the material block 120. For the material blocks 120 with qualified surface flatness, they are transferred to the weighing station of the weighing device 160 through the detection transfer component, while the material blocks 120 with unqualified surface flatness are unloaded.

[0086] In a preferred embodiment, in step S6, the weighing device 160 weighs the material block 120 at the weight station (weight information), inkjet codes the material block 120 with qualified weight through the inkjet printer 161, and discharges the material block 120 with unqualified weight.

[0087] In a preferred embodiment, in step S7, the stacking robot 180 clamps the coded material block 120 through the stacking claw 181, and moves the material block 120 to the corresponding position of the third camera 190. The third camera 190 performs a bottom appearance inspection on the material block 120. The stacking robot 180 places the material blocks 120 that are judged to be qualified in bottom appearance to the qualified product unloading station, and the unqualified or suspected unqualified material blocks 120 are placed to the unqualified product unloading station.
