[0031] like Figure 1 and Figure 2 As shown, a normal grasping protection mechanism for an ampoule holder includes a support frame 21, a first cylinder 22 is mounted on the support frame 21, a grasping assembly 23 is mounted at the bottom of the first cylinder 22, and the grasping assembly 23 is used to grasp the ampoule holder and calibrate the position of the ampoule holder on the conveyor line.

[0032] In the embodiment disclosed in the present utility model, the grabbing assembly 23 includes a frame 231, a grabbing portion 235 is provided at the bottom of the frame 231, a second cylinder 232 is installed on the frame 231, and a first push plate 233 and a second push plate 234 are slidingly provided on both sides of the frame 231. The facing sides of the first push plate 233 and the second push plate 234 are elastically connected to the frame 231, and the active end of the second cylinder 232 is fixedly connected to a push rod 2321, which pushes the first push plate 233 and the second push plate 234 to move away from each other.

[0033] In the embodiment disclosed in the present utility model, a connecting block 2311 is fixedly provided on the top of the frame 231. The connecting block 2311 is located between the first push plate 233 and the second push plate 234. A threaded hole is opened in the center of the connecting block 2311. The connecting block 2311 is threadedly fixedly connected to the piston cylinder of the first cylinder 22.

[0034] A first spring 2332 is provided between the first push plate 233 and the connecting block 2311 , and a second spring 2342 is provided between the second push plate 234 and the connecting block 2311 . When the first spring 2332 and the second spring 2342 are in a natural state, the first push plate 233 and the second push plate 234 both remain in contact with the frame 231 .

[0035] In the embodiment disclosed in the present utility model, a first inclined block 2331 is fixedly provided on one side of the first push plate 233 close to the connecting block 2311 , and a second inclined block 2341 is fixedly provided on one side of the second push plate 234 close to the connecting block 2311 corresponding to the first inclined block 2331 ;

[0036] A slideway 2312 is further provided on the top of the frame 231 , and the push rod 2321 pushes the first inclined block 2331 and the second inclined block 2341 synchronously to push the first push plate 233 and the second push plate 234 to move away from each other along the slideway 2312 .

[0037] In the embodiment disclosed in the present utility model, the push rod 2321 is in the shape of "]", and pulleys 2322 are rotatably provided at both ends of the action part of the push rod 2321. When the push rod 2321 moves, the pulleys 2322 rotate on the surfaces of the first inclined block 2331 and the second inclined block 2341 respectively to push the first push plate 233 and the second push plate 234 to move away from each other.

[0038] Furthermore, the first inclined block 2331 and the second inclined block 2341 are both provided with an inclined portion and a straight portion.

[0039] like Figure 4 and Figure 5As shown, when the pulley 2322 rotates on the inclined portions of the first inclined block 2331 and the second inclined block 2341, the pulley 2322 generates a force on the inclined portions of the first inclined block 2331 and the second inclined block 2341 to move away from each other, and the push rod 2321 then pushes the first push plate 233 and the second push plate 234 to move away from each other;

[0040] like Figure 6 and Figure 7 As shown, when the pulley 2322 rotates on the straight parts of the first inclined block 2331 and the second inclined block 2341, the force exerted by the pulley 2322 on the straight parts of the first inclined block 2331 and the second inclined block 2341 is offset by the contraction force generated by the first spring 2332 and the second spring 2342, so that the first push plate 233 and the second push plate 234 remain stationary and the distance between them is maximized.

[0041] In the embodiment disclosed in the present utility model, a first gripping block 2333 is provided at the bottom of the first push plate 233, and a second gripping block 2343 is provided at the bottom of the second push plate 234. When the first push plate 233 and the second push plate 234 are both kept in contact with the frame 231, the first gripping block 2333 and the second gripping block 2343 synchronously lift the ampoule holder.

[0042] like Figure 3 As shown, the grabbing portion 235 includes a receiving groove 2351 , a first protective plate 2352 is elastically provided at the top of the receiving groove 2351 , a baffle 2354 is provided at the tail of the receiving groove 2351 , and a second protective plate 2353 is elastically provided on the baffle 2354 .

[0043] After the grabbing portion 235 descends to the preset position of the ampoule holder conveyor line, the ampoule holder enters the receiving groove 2351. The baffle 2354 at the tail of the receiving groove 2351 blocks the movement of the ampoule holder, thereby realizing the grabbing operation of the ampoule holder, and the elastically arranged second protective plate 2353 can buffer the impact force of the baffle 2354 on the side of the ampoule holder to prevent the ampoule from deforming.

[0044] When the gripping portion 235 presses down the ampoule holder, the elastically arranged first protective plate 2352 can effectively buffer the downward pressure on the ampoule holder, thereby preventing the ampoule holder from being deformed or even damaged by the pressure.

[0045] In the embodiment disclosed in the present invention, the cross-sectional shape of the first protective plate 2352 and the second protective plate 2353 can be circular or polygonal, which is not limited here.

[0046] like Figure 8As shown, a structural schematic diagram of an ampoule production tray conveyor line is shown, which includes an ampoule conveyor belt 1, a dial wheel 3, a downward inclined slope plate 4 and an ampoule tray conveyor line 7 arranged in sequence, an ampoule tray normal grasping protection mechanism 2 is arranged on the ampoule tray conveyor line 7, the dial wheel 3 is installed behind the dial wheel 3, an ampoule falling buffer device is installed above the slope plate 4, the ampoule tray conveyor line 7 is installed below the slope plate 4, and an ampoule leveling device 9 is installed on the ampoule tray conveyor line 7.

[0047] Among them, a guide strip 6 is provided at the tail of the ampoule falling buffer device, the ampoule falling buffer device can be a brush 5, the brush 5 is parallel to the slope plate 4, and the leveling device 8 can be a rotating sponge wheel, which is fixed above the ampoule holder conveyor line 7 through a bracket. The uneven ampoules entering the ampoule holder are leveled under the pressing action of the rotating sponge wheel.

[0048] The working principle of this utility model:

[0049] The ampoules are transported to the ampoule tray transported on the ampoule tray conveyor line 7 through the ampoule conveyor belt 1, the thumbwheel 3 and the inclined plate 4. In order to ensure that the ampoules fall into the ampoule tray, the conveying speed of the ampoule tray conveyor line 7 is slightly faster than the conveying speed of the ampoule conveyor belt 1. Therefore, the ampoule trays will gradually accumulate on the ampoule tray conveyor line 7, affecting the normal production progress.

[0050] In the initial state, the second cylinder 232 extends the piston rod to make the pulley 2322 contact the straight parts of the first inclined block 2331 and the second inclined block 2341, so that the first push plate 233 and the second push plate 234 remain stationary and the distance between them is maximized.

[0051] When ampoule trays are overstocked, the first cylinder 22 outputs the piston rod to drive the grab assembly 23 to drop to a preset position on the ampoule tray conveyor line 7. The ampoule trays enter the receiving groove 2351 and are blocked by the baffle 2354, thereby controlling the ampoule tray conveying speed.

[0052] The second cylinder 232 retracts the piston rod, and the first push plate 233 moves toward each other synchronously under the contraction force of the first spring 2332, and the second push plate 234 moves synchronously under the contraction force of the second spring 2342. The first grasping block 2333 and the second grasping block 2343 synchronously lift the ampoule holder and calibrate the position of the ampoule holder in the receiving groove 2351 to the middle of the ampoule holder conveying line 7.

[0053] When the backlog of ampoule trays is relieved, the second cylinder 232 extends the piston rod, so that the first push plate 233 and the second push plate 234 release the ampoule trays. Then, the first cylinder 22 retracts the piston rod and drives the grabbing assembly 23 to rise. The ampoule trays in the receiving groove 2351 continue to be transported to the next process via the ampoule tray conveyor line 7.

[0054] For ordinary technicians in this field, based on the teachings of this utility model, without departing from the principles and spirit of this utility model, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of this utility model.
