Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an automatic drug stripping system through visual recognition. Background Art

[0002] Tablets and capsules are commonly packaged in PTP (Preformed Plastic Packaging) sheets using heat-pressing and plastic sealing machines. This aluminum foil blister packaging structure offers numerous advantages for users, including convenience, hygiene, isolation from air and humidity that can affect drug stability, and optimized storage conditions. When needed, the PTP sheet can be gently squeezed from the back. Currently, in major hospitals and pharmacies, some medications often require removal of their packaging for larger quantities. However, manual stripping of drug packaging is time-consuming, labor-intensive, and inefficient, and it can damage the hands, making it unsuitable for current medical needs. Consequently, automated stripping machines have been developed.

[0003] However, the existing automatic pill stripping machine requires manual adjustment of the position of the positioning block when clamping the pill board, and manual adjustment of the number of the paddles to correspond to the number of rows of pills in the pill board, which cannot achieve a good automation effect.

[0013] Preferably, the paddle self-positioning mechanism includes a slider fixed to the second driving mechanism, a paddle is provided on one side of the slider for rotating in the vertical direction, and a servo steering engine is provided on the other side. The servo steering engine passes through the slider and is fixed to the paddle and controls the paddle to switch between the third position and the fourth position.

[0030] The present invention will be described in further detail below with reference to specific embodiments:

[0031] like Figure 1 、 Figure 2 and Figure 3As shown, an automated drug stripping system based on visual recognition includes a fixed main body 1, on which a loading platform 11 arranged in a horizontal direction is fixed, which is used to prevent the drug plate from moving. A feed port is provided at one end of the loading platform 11 along the first direction. A drug stripping rubber roller 4 is provided in the main body 1, which applies vertical pressure to the drug plate and drives the drug plate to enter the feed port along the first direction by its own rotation. The positioning block self-positioning mechanism 2 is used to limit the drug plate to a preset position. The paddle self-positioning mechanism 3 is used to break the seal of the drug plate and cooperate with the drug stripping rubber roller 4 to peel the tablets from the drug plate. The visual positioning mechanism 6 is provided directly above the loading platform 11, and is used to identify the width of the drug plate and the number of rows of tablets, and to control the movement of the positioning block self-positioning mechanism 2 and the paddle self-positioning mechanism 3 along the second direction so that they correspond to the width of the drug plate and the number of rows of tablets, respectively.

[0032] like Figure 4 As shown, the positioning block self-positioning mechanism 2 includes a positioning block arranged parallel to the stage 11, and the positioning block performs opening and closing movements along a second direction perpendicular to the first direction, including a first positioning block 21 fixed to the main body 1, and a second positioning block 22 cooperating with the first positioning block 21 and moving along the second direction under the action of the first driving mechanism 23. The first positioning block 21 and the second positioning block 22 are in the same horizontal plane. Among them, the first driving mechanism 23 includes a first screw assembly and a first motor 231 for driving the first screw assembly, the first screw assembly includes a first screw 232 and a first nut 233 arranged along the second direction, and the second positioning block 22 is fixed on the first nut 233. The positioning block self-positioning mechanism 2 includes two guide shafts 24 arranged parallel to the first screw, and both guide shafts 24 are arranged through the first nut 233, and both ends are fixed to the main body 1 respectively.

[0033] like Figure 5 As shown, the paddle self-positioning mechanism 3 includes a main shaft 31 arranged along the second direction, a plurality of paddles 32 are coaxially arranged on the main shaft 31, and a slider 33 fixed to the second driving mechanism. A paddle 34 is arranged on one side of the slider 33 for rotation in the vertical direction, and a servo servo 35 is arranged on the other side. The servo servo servo 35 passes through the slider 33 and the paddle 34 and controls the paddle 34 to switch between the third and fourth positions. When the paddle 34 is in the third position, it can hold and move several paddles 32 to slide along the main shaft 31 and switch between the first and second positions, so that the number of paddles 32 in the first position corresponds to the number of rows of tablets.

[0034] The paddles 32 are circular and include a cutting portion at the edge and a protruding boss at the center. The cutting portion is used to cut the seal of the medication. When adjacent paddles 32 abut against each other, the boss ensures that the cutting portions of the abutting paddles 32 maintain a predetermined gap that corresponds to the row spacing of the tablets in the medication board.

[0035] The main body 1 also houses a shelling roller 5, horizontally positioned forward of the stripping roller 4 relative to the first direction. Bristles are evenly distributed radially along the roller 5. The shelling roller 5 rotates about its axis to discharge the stripped tablets from the tablet sheet. The stripped tablets enter a discharge plate 7 below the loading platform 11 and are collected.

[0036] While working:

[0037] 1. Manually place the medicine plate on the loading platform 11 and make the left side of the medicine plate fit with the first positioning block 21.

[0038] 2. The visual positioning mechanism 6 identifies the width of the medicine plate, controls the first driving mechanism 23 to drive the second positioning block 22 to move, and self-positions to the right side of the medicine plate and cooperates with it.

[0039] 3. The visual positioning mechanism 6 identifies the number of rows of tablets in the medicine plate and controls the second driving mechanism to drive the shifting claws 34 to drive a corresponding number of shifting pieces 32 to enter the first station.

[0040] 4. The stripping roller 4 rotates around its own axis and cooperates with the paddle 32 to peel the tablets from the medicine board. Then the shelling roller 5 discharges the medicine board after the tablets are peeled. The tablets enter the discharge plate 7 below the loading platform 11 and are collected.

[0041] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
