[0042] like Figure 4 As shown, the cutting mechanism includes a cutting installation chamber 92, in which a cutting pressing cylinder 91 is installed. An integral cutting frame blade 93, composed of individual cutting frame blades 78, is mounted on the cutting pressing cylinder 91. The worktable 1 is also provided with a cutting frame body 94 corresponding to the position of the integral cutting frame blade 93. The cutting frame body 94 is provided with a cutting area 904 corresponding to the position of each individual cutting frame blade 78. When the cutting pressing cylinder 91 moves down, each individual cutting frame blade 78 extends into the cutting area 904 to cut the packaged medicine in the whole plate. A hopper 905 is also provided below the cutting frame body 94, and a finished product receiving frame 906 is also provided below the hopper 905.

[0043] like Figure 5 and Figure 6 As shown, the workbench 1 is also equipped with a cutting frame 94 corresponding to the position of the empty package installation chamber 71. The cutting frame 94 is equipped with a cutting area 904. The individual cutting frame blade 78 is adjusted according to the position of the lead screw motor 72 to select the cutting position of the empty package. After the individual cutting frame blade 78 moves down, it cuts off the plate of medicine from the empty package.

The two dispensing claws realize the feeding of the tablet, and the two vision sensors realize the detection of the tablet feeding. The processor 43 is connected to the vision sensors.

[0045] like Figure 8 As shown, the hot pressing forming mechanism 3 for medicine tank includes a forming installation chamber 32, in which a forming pressing cylinder 31 is installed. The forming pressing cylinder 31 is equipped with a hot pressing upper mold 33 for medicine tank, while the worktable 1 below is equipped with a hot pressing lower mold 34 for medicine tank corresponding to the position of the hot pressing upper mold 33.

[0046] like Figure 9 As shown, the film coating mechanism 5 includes a film coating bracket 52, with an aluminum film feeding roller 51 at the upper end and a guide roller 53 at the lower end. The aluminum film fed out by the guide roller 53 is correspondingly bonded to the PVC board 21.

[0047] like Figure 10 As shown, the aluminum sealing hot pressing mechanism 6 includes a hot pressing mounting chamber 62, in which a hot pressing pressing cylinder 61 is installed. A hot pressing coating upper mold 63 is installed on the hot pressing pressing cylinder 61, and a hot pressing coating lower mold 64 corresponding to the position of the hot pressing coating upper mold 63 is provided on the worktable 1.

[0048] like Figure 10 and Figure 11 As shown, an auxiliary moving mechanism 8 is also provided between the empty package cutting mechanism 7 and the straightening mechanism 9. The moving mechanism includes a moving cylinder 86, a sliding sleeve 84 is installed at the end of the moving cylinder 86, a sliding rod 85 is fitted inside the sliding sleeve 84, the sliding rod 85 is fixed on the worktable 1, a concave plate 83 is installed at the upper end of the sliding sleeve 84, a pressing cylinder 81 is installed on the concave plate 83, and a clamping plate 82 is installed at the lower end of the pressing cylinder 81.

[0049] The concave plates 83 are set on both sides of the PVC plate 21. After the pressing cylinder 81 presses down, the PVC plate 21 is pressed into the concave plates 83 by the clamping plate 82, and can move accordingly with the moving cylinder 86.

[0050] The overall working process of this invention is as follows: First, the PVC sheet is released through the PVC feeding roller. When it passes through the hot pressing forming mechanism of the medicine tank, the upper pressing cylinder drives the upper mold of the medicine tank to press down in conjunction with the lower mold of the medicine tank to press out the medicine tank, thus completing the medicine tank pressing work. Specifically, as follows... Figure 12 As shown.

[0051] Next, the tablets enter the tablet filling and identification mechanism. The first dispensing motor drives the first dispensing claw to rotate, dispensing the tablets into the medicine slot. The first vision sensor detects whether there is an unfilled medicine slot. Then, the second motor drives the second dispensing claw to rotate and fill the slot. The second vision sensor then detects whether there is an empty package. The design of the dispensing motor and the dispensing claw in the above process is based on existing dispensing and feeding technology, which can achieve feeding.

[0052] Next, the aluminum film enters the laminating mechanism. The aluminum film is released by the aluminum film feeding roller and overlaps with the PVC board via the guide roller. It then enters the aluminum sealing hot-pressing mechanism. The pressing cylinder drives the hot-pressing laminating upper mold to press down, fusing the PVC board and aluminum film together, thus completing the aluminum film heat-sealing step. Specifically... Figure 13 As shown.

[0053] Afterwards, if there are no empty packages, the empty package cutting mechanism is used directly. If there are still empty slots, the processor adjusts the individual cutting frame blades in the empty package cutting mechanism according to the pre-detected empty package position. Specifically, the position adjustment is achieved through the cooperation of the lead screw motor, the spiral lead screw, and the nut. According to the position of the medicine slot on the PVC board, there are multiple individual cutting frame blades arranged side by side, and there is a corresponding whole cutting frame on the worktable below. The whole cutting frame has a cutting area corresponding to the position of the individual cutting frame blade. So, as long as the position of the individual cutting frame blade is adjusted, after moving downward, the board with empty medicine slots in the corresponding cutting area can be cut off and fall into the waste collection box through the hopper.

[0054] In the above process, instead of directly cutting off a single empty medicine trough, the entire trough containing the empty medicine trough is cut off, such as... Figure 13 and Figure 14 As shown, there are six blister packs of medicine. If a blank blister pack is detected, the medicine in that blister pack can be cut off. The cutting area of ​​the individual cutting frame blade is adapted to the size of each PVC blister pack, thus completing the removal of the empty package.

[0055] Next, it will enter the cutting mechanism. The cutting mechanism is similar to the empty package cutting mechanism, but the upper cutting mechanism is set as an integral cutting frame composed of six individual cutting frame blades. The structure of the lower cutting frame is the same, with a cutting area inside. After the upper integral cutting frame blade moves down, it can cut off all the partitioned medicine plates and enter the finished product receiving frame below from the hopper to complete the cutting.

[0056] Furthermore, after the cutting is completed, there are still many adhesive parts on the PVC board besides the cut part, so it can be directly collected and wound along with the receiving roller. In addition, because the PVC board's ability to move with the PVC feeding roller and receiving roller is reduced after cutting, it may break in the middle due to the cutting. Therefore, this device is also specifically equipped with an auxiliary moving mechanism to assist in the movement of the PVC board.

[0057] In practical use, the transmission method of this invention needs to be designed as a stepping structure. Not only the moving distance and the dwell time, but also the other aspects must conform to the working process of each station, and can be designed according to the actual usage. The auxiliary moving mechanism also utilizes the stepping movement method to assist in the movement of the PVC substrate.

[0058] The clamping cylinder can press the edge of the PVC sheet into the concave plate. The concave plate can be moved by the cooperation of the collar and the sleeve rod and by the movement cylinder. Therefore, the clamped PVC sheet can be moved by the movement cylinder.

[0059] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the implementation of the present invention or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of patent protection of the present invention should be included within the scope of the present invention patent application.
