In addition, when tablet pharmaceuticals are compressed by a tablet press, in order to determine that the packaged tablets have a complete appearance, the tablet inspection is mostly performed by imaging and graphic contrast inspection, and partially by manual visual inspection. In the latter case, the detection omission factor is large and is gradually replaced. The former can clearly judge whether the tablet exists, whether the tablet is damaged or not through imaging and graph comparison, and the like, and when the tablet is packaged, the tablet is placed on the bearing plate through the even distributor in an array, so that the tablet is easily damaged in the even distribution process, for example, microcracks are formed on the tablet, and in the subsequent conveying process, the microcracks are expanded and penetrate through the tablet, so that the tablet is split. These microcracks are not usually observed by the imaging device, and powder adhered to the tablets in the process of uniform distribution is easy to block the microcracks, so that the problem of missed detection finally occurs, for example, if the tablets are split in the packaging process, reworking is needed for packaging again or new tablets are needed for filling, and if the tablets enter a sales link, the quality of products is easy to be adversely affected.

In this embodiment, when the tablet is placed and transferred, the following method is adopted:

In the detection, tablets are placed on the placement table 58 in each vertical hole 55, and the tablets are restrained by the positioning arc grooves 59 so that the convex arc surfaces of the tablets are in contact with the positioning arc grooves 59, after placement, an operator transfers the carrier plate 50 and the tablets thereon to the position right below the detection head 7, and then performs the detection operation of the hardness and the like of the tablets, in the detection process, the position of the carrier plate 50 can be adjusted by means of the electric cylinders with the two movement directions being perpendicular to each other, and each tablet can be detected by adjustment, and in order to avoid movement of the tablet during transfer, a corresponding pressing plate can be provided on the carrier plate 50, and an upper positioning groove is provided on the pressing plate, each tablet is positioned by the positioning groove and the pressing plate under pressure, and in the detection, the pressing plate needs to be detached.

In this embodiment, the detection process is described by taking the detection of a single tablet as an example:

During the inspection process, the first motor 604 is started to rotate the eccentric 605, the rotation of the eccentric 605 causes the collar 607 to swing, the swinging of the collar 607 causes the spline shaft 619 to move vertically under the guide of the spline sleeve 620, and the movement of the spline shaft 619 drives the inspection tray 707 to move vertically up and down.

If there is no tablet directly under the detection plate 707, the angle between the first link 611 and the second link 613 is not changed by the second spring 616 because the detection plate 707 is not acted on by the upward force, and the photoelectric sensor provided on the middle block 614 detects that there is no change in the grating on the movable rod 615 or disturbance in a predetermined range because there is no relative movement between the middle block 614 and the movable rod 615, the state of missing tablet at this time can be known, and when detecting tablet on the carrier plate 50 is specifically reflected, it is possible to determine that tablet in a certain vertical hole 55 is missing by the above expression, and record the missing.

If there is a tablet directly under the detection disc 707, the lower end of the detection disc 707 will be brought into contact with the tablet when the detection disc 707 moves downward, and thus the detection disc 707 receives an upward reaction force, the presence of which will prevent the connection recess 618 from continuing to move downward, and after the connection recess 618 stops moving, when the collar 607 continues to swing downward, the collar 607 will be brought closer to the V-shaped plate 610, and thus the angle between the first link 611 and the second link 613 will be reduced, so that the middle block 614 moves outward in the axial direction of the movable rod 615, and the second spring 616 will be compressed during the movement, while the photoelectric sensor provided on the middle block 614 knows the number of movements of the grating on the movable rod 615, and thus eventually the hardness of the tablet, and when the detection disc 707 moves downward, downward pressure is applied to the tablet, if there is a tablet, the tablet will also be crushed at this time.

When detecting the presence or absence of micro cracks in a tablet, the detecting disc 707 moves downward under the swinging of the collar 607 while allowing the detecting disc 707 to exert a force on the tablet, and when the tablet is in contact with the lower end of the detecting disc 707, the positioning cylinder 713 drives the positioning sleeve 714 to move upward while canceling the restriction of the positioning sleeve 714 to the tapered column 712, at which time the tapered column 712 and the movable ring 711 can move in the radial direction thereof, and when a downward force is exerted, the tablet will be broken by the detecting disc 707 and part of the tablet will even be crushed, and when the tablet breaks, the detecting disc 707 will be tilted, and this tilting will allow the movable ring 711 to move in the annular groove 702, and the tablet will be broken and marked by moving the grating ring provided in the annular groove 702 and the photoelectric sensor provided on the movable ring 711.
