[0016] 1.

Detailed implementation mode

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] As shown in Figures 1 - 11As shown, the present invention comprises a frame 1 and a gluing device 2, a lining moving device 6 and a lining rolling device 3 arranged on the upper side of the frame 1. A lining lifting mechanism 8 is arranged inside the frame 1, wherein the gluing device 2 is provided with a glue brush 202 having three degrees of freedom of movement of X, Y and Z. When the present invention is working, the flexible lining paper 7 (i.e., lining) to be assembled is first lifted to the lining loading station on the upper side of the frame 1 by the lining lifting mechanism 8, and then the flexible lining paper 7 is moved by the glue brush 202 to be glued on the upper surface, and then the glued flexible lining paper 7 is driven by the lining moving device 6 to be sent to the lining waiting rolling station on the upper side of the frame 1, as shown in Figures 1 - 5 As shown in , the roll lining device 3 includes a roll lining Y-axis driving assembly and a rotating shaft 303, and the rotating shaft 303 is driven by the roll lining Y-axis driving assembly to move along the Y direction, as shown in Figure 5 As shown in , a roller core 311 is provided at the front end of the rotating shaft 303, and the roller core 311 rotates synchronously with the rotating shaft 303, as shown in Figures 2 - 5 As shown in , the outer surface of the roller core 311 is provided with a suction cup 3082, the lining waiting to roll station is arranged on one side of the roller core 311, and the flexible lining paper 7 on the lining waiting to roll station extends to the lower side of the edge of the roller core 311, so that Figure 3 As shown in , when the roller core 311 rotates counterclockwise upward, the suction cup 3082 on the roller core 311 can absorb the lower surface of the flexible backing paper 7 without glue, and make the upper surface of the flexible backing paper 7 with glue face outward, and as shown in Figure 4 As shown in , the roller core 311 continues to rotate, which drives the flexible lining paper 7 to roll up. A fixed limiting plate 310 is provided on the side of the roller core 311 away from the lining waiting rolling station. Due to the special characteristics of the cartridge 4 with a small mouth and a large cavity, the flexible lining paper 7 must be rolled into one and a half circles to reduce the diameter before it can be put into the cartridge 4. Therefore, as shown in Figure 4 As shown in , the last half circle of the flexible backing paper 7 is realized by the limit plate 310, and the limit plate 310 abuts against the uncoated part of the flexible backing paper 7 to avoid adhesion with the flexible backing paper 7. In addition, as shown in Figure 4 As shown in , the limit plate 310 also ensures that there is enough space between the last half circle of flexible backing paper 7 and the inner layer of flexible backing paper 7 to prevent the flexible backing paper 7 from sticking to itself. As shown in Figure 1 As shown in FIG. 1 , a seat body 5 is provided on one side of the frame body 1, and a medicine cartridge 4 to be assembled is provided on the seat body 5, and the rotating shaft 303 is aligned with the opening of the medicine cartridge 4. When the flexible backing paper 7 is fully rolled up, the rotating shaft 303 together with the roller core 311 at the front end is driven by the roll lining Y-axis driving assembly to move forward along the Y direction, so that the flexible backing paper 7 rolled up on the roller core 311 is sent into the medicine cartridge 4. During this process, the limiting plate 310 does not move, so that when the flexible backing paper 7 completely enters the medicine cartridge 4, the flexible backing paper 7 is separated from the suction cup 3082 and adheres to the inner wall of the medicine cartridge 4 through its own rebound characteristics and the reverse blowing of the suction cup 3082.​

In this embodiment, the roll lining rotation driving device 302 includes a roll lining motor 3021 and a roll lining speed reducer 3022.

[0042] The working principle of the present invention is:

[0043] When the present invention works, the flexible backing paper 7 (i.e., the lining) to be assembled is first lifted to the lining loading station on the upper side of the frame body 1 by the lining lifting mechanism 8, and then the flexible backing paper 7 is moved by the glue brush 202 to apply glue on the upper surface. Then, the glued flexible backing paper 7 is driven by the lining moving device 6 to the lining waiting-to-be-rolled station on the upper side of the frame body 1. When the lining moving device 6 works, the moving plate 605 and the lifting slide cylinder 603 thereon are driven to move by the rodless cylinder 601. After moving in place, the moving plate 605 is then driven to descend by the lifting slide cylinder 603, and the moving suction cup 604 is used to pick up the flexible backing paper 7 on the lining lifting mechanism 8, and the moving suction cup 604 adsorbs the unglued edge of the flexible backing paper 7 to avoid adhesion.

[0044] After the flexible backing paper 7 is sent to the lining waiting-to-be-rolled station, the flexible backing paper 7 on the lining waiting-to-be-rolled station extends to the lower side of the edge of the drum core 311. Then, the rotating shaft 303 in the lining rolling device 3 starts and drives the drum core 311 to rotate to roll up the flexible backing paper 7 on the lining waiting-to-be-rolled station. As Figures 3 - 4 shown, when the drum core 311 rotates counterclockwise upward, the suction cup 3082 on the drum core 311 can adsorb the unglued lower surface of the flexible backing paper 7, so that the glued upper surface of the flexible backing paper 7 faces outward. A fixed limit plate 310 is provided on the side of the drum core 311 away from the lining waiting-to-be-rolled station. Due to the speciality of the small mouth and large cavity of the cartridge 4, the flexible backing paper 7 needs to be rolled into one and a half circles to reduce the diameter before it can be put into the cartridge 4. Therefore, as Figure 4 shown, the last half circle of the flexible backing paper 7 is realized by relying on the limit plate 310. The limit plate 310 abuts against the unglued part of the flexible backing paper 7 to avoid adhesion to the flexible backing paper 7. In addition, the limit plate 310 also needs to ensure that there is enough space between the last half circle of the flexible backing paper 7 and the inner layer of the flexible backing paper 7 to avoid self-adhesion of the flexible backing paper 7. At the same time, as Figure 5 shown, the limit plate 310 is fixed on the fixed rod 304 and does not move. And as Figure 1 shown, a guiding conical cylinder 306 is provided on the frame body 1 to guide the flexible backing paper 7 into the cartridge 4 to prevent the flexible backing paper 7 from opening and having a diameter larger than the opening of the cartridge 4 and thus being unable to enter.

[0045] When the flexible backing paper 7 is completely rolled up, the rotating shaft 303 together with the front drum core 311 is driven to move forward along the Y direction by the lining rolling Y-axis drive assembly, so that the flexible backing paper 7 rolled up on the drum core 311 is sent into the cartridge 4. During this process, the limit plate 310 does not move.
