s2, then, a worker needs to detect the size of the object of the label according to actual needs, placing a smaller object of the label to be detected between the embedding groove (32) and the groove (33), or embedding the groove (33) and the inner side of the embedding groove (32), then fixing the L plate (42) to fixedly mount the adjusting seat (37), placing a larger object of the label to be detected between two elastic cottons (38), extruding the positioned object of the elastic cottons (38) by self-resilience, or rotating the threaded rod (45) to move in a direction away from the stay (39), so that the retracted threaded rod (45) can be unfolded for being used for sleeving the cylindrical object of the label to be detected, and the placed object and the object need to ensure that the label is exposed;

s3, a worker needs to operate a switch (6) to start a motor (12) to enable a transmission belt (15) to rotate, so that placed material objects needing to detect labels can move from left to right, the material objects pass through a laser detection camera (11), the plurality of laser detection cameras (11) shoot label conditions on the material objects in an omnibearing manner under the support of a bracket (10), a shooting picture is transmitted to a host (3) to process and analyze received picture data, the picture data is transmitted to a display screen (7) to be displayed, and the display screen (7) displays the picture for people to reference and is matched with the host (3) to detect the labels;

S4, simultaneously, a worker needs to start a motor (24) to enable a cam (25) to rotate, periodically push a push plate (21), enable a push rod (22) to penetrate through a through hole (20) to move a pressing spring (23) to the right side, push an L rod (28), enable the inner side of an L rod (28) inserted into a groove (33) to push a material object placed on the inner side of the groove (33), enable the material object which is qualified to be detected to push down to the inner side of a guide cover (50) from the inner side of the groove (33), and simultaneously, when the cam (25) is separated from the push plate (21), enable the spring (23) to push the push plate (21) to move to the left side along a supporting rod (19) by utilizing rebound force, and enable the L rod (28) to move to the left side to wait for the next insertion into the groove (33);

s5, when the threaded rod (45) is used for sleeving the material articles and the elastic cotton (38) is used for extruding and clamping the material articles, the material articles qualified in detection of the labels touch the shifting block (49) when the material articles move along with the rotation of the conveying belt (15), the shifting block (49) shifts the material articles, the material articles slide off the outer side of the threaded rod (45), or the elastic cotton (38) is extruded to enable the material articles to move out from between the two elastic cotton (38) to the outside, meanwhile, the spring II (48) and the splayed sleeves (47) deform and store energy, and rebound upwards by utilizing the elastic force when the external force disappears, so that the material articles are better forced to separate from the threaded rod (45) and the elastic cotton (38) and fall to the inner side of the guide cover (50);

S6, workers can manually take out unqualified material articles from the top of the inner plate (9) to be voided, after the work is completed, the workers can operate the processing unit to stop the motor (12) and the motor (24) to run, and then the driving machine (62) is started to drive the winding wheel (63) to rotate the winding pull rope (61) clockwise, so that the pull rope (61) is wound to the outer side of the winding wheel (63), the pull rope (61) can be gradually straightened in the winding process, the pull rope (61) is gradually straightened along with gradually pushing the storage box (56) to the front side, the storage box (56) is moved to the outside from the inner side of the frame (1), and the workers can conveniently take out the material articles of qualified labels which are collected by transferring the storage box (56).

9. The method of claim 8, wherein the step of using the machine vision-based label detection device comprises: in the step S5, the method further includes the following steps:

s51, the arc block (54) is contacted with a material object which is not moved out of the shifting block (49) to the outside accidentally, the reed (55) and the spring III (52) are pushed to deform by the connecting block (53) through the reaction force, meanwhile, the arc block (54) is pushed to swing left and right by the repulsive force of the reed (55) and the spring III (52), and the material object is forced to separate from the threaded rod (45) and the elastic cotton (38) from the position of the arc block (54) and fall between the cover plate (51) and the guide cover (50).
