[0044] The labeling mechanism 401 is used to stick the label to the blister box 90 in the second channel 71.

[0061] The output end of the arc channel 61 is connected to a second linear guide groove 67, the bottom of which extends obliquely downward from front to back, and the bottom of the second linear guide groove 67 has a third avoidance groove (not shown) for the movement of the material-shifting piece 652, and the angle between the bottom of the second linear guide groove 67 and the horizontal plane is ≤5 degrees; by setting the bottom of the second linear guide groove 67 to extend obliquely upward along the conveying direction of the blister box 90, when the material-shifting piece 652 pushes the blister box 90 to the second linear guide groove 67, the blister box 90 has a tendency to tilt and slide backward, so that the previous blister box 90 and the subsequent blister box 90 can be better stacked together, and the stacking effect is better. When the angle between the bottom of the second linear guide groove 67 and the horizontal plane is ≤5 degrees, it is beneficial for the material-shifting piece 652 to shift the stacked blister boxes 90 to creep forward, thereby freeing up stacking space for subsequent blister boxes 90.

[0062] A platform 80 is provided at the output end of the second linear guide groove 67, and a material moving component 68 is provided on one side of the platform 80. The material moving component 68 can intermittently push the blister boxes 90 stacked in the second linear guide groove 67 forward to the platform 80, and support the subsequent blister boxes 90 in the second linear guide groove 67 to prevent the blister boxes 90 from tipping forward; by setting the platform 80 and the material moving component 68, when moving materials, the material moving component 68 intermittently pushes the blister boxes 90 stacked in the second linear guide groove 67 to the platform 80, and at the same time supports the subsequent blister boxes 90 in the second linear guide groove 67 to prevent the plastic boxes from tipping forward, so that the subsequent blister boxes 90 can be stacked smoothly.

The driving end of the second driving unit 683 is connected to a material shifting rod 684 which can extend into or out of the second linear guide groove 67. The first driving unit 682 drives the material shifting seat 681 to move so that the material shifting rod 684 intermittently pushes the blister boxes 90 stacked in the second linear guide groove 67 forward to the platform 80, and supports the subsequent blister boxes 90 in the second linear guide groove 67 to prevent the blister boxes 90 from tipping forward. Specifically, the first driving unit 682 can adopt a driving mode selected from a linear motor, a synchronous belt + a stepping motor, and a screw rod + a stepping motor. The second driving unit 683 is arranged directly above the second linear guide groove 67. The second driving unit 683 can adopt a cylinder.

[0064] A third conveyor belt 81 is provided on one side of the platform 80 , and a third driving unit 82 is provided on the other side of the platform 80 . The third driving unit 82 can push the blister boxes 90 stacked on the platform 80 to the third conveyor belt 81 . Specifically, the third driving unit 82 can be a cylinder.

[0065] The flip stacking mechanism 60 also has a quantity detection component (not shown). When the quantity detection component detects that the blister boxes 90 in the second linear guide groove 67 are stacked to the target quantity, the material shifting component 68 pushes the stacked blister boxes 90 whose quantity has been counted in the second linear guide groove 67 forward to the platform 80. The quantity detection component has a sensor. The sensor can count the number of stacked blister boxes 90 by detecting the number of revolutions of the rotating frame 63, or can count the number of stacked blister boxes 90 by detecting the number of times the material shifting piece 652 shifts the blister boxes 90. By setting the quantity detection component, the number of stacked blister boxes 90 can be counted without stopping the machine, and the stacked blister boxes 90 whose quantity has been counted can be quickly pushed out to the platform 80 by using the material shifting component 68, so as to achieve high automation efficiency.

When the material shifting piece 652 rotates to the first linear channel, the material shifting piece 652 is in a horizontal state, and when the material shifting piece 652 rotates to the arc channel 61, the material shifting piece 652 is in an inclined state, and when the material shifting piece 652 rotates to the second linear guide groove 67, the material shifting piece 652 is in a vertical state, and the material shifting piece 652 shifts the blister box 90 in the first linear channel to pass through the arc channel 61 and the second linear guide groove 67 in sequence, and the blister box 90 is adjusted from a lying position to a standing position In this state, the front blister box 90 abuts against the material shifting rod 684, and the rear blister box 90 is stacked with the front blister box 90. During the stacking of the blister boxes 90, the first driving unit 682 drives the material shifting seat 681 to move forward intermittently, and the material shifting seat 681 drives the second driving unit 683 and the material shifting rod 684 to move forward synchronously and intermittently, so that the material shifting rod 684 pushes the stacked blister boxes 90 onto the platform 80. When the quantity detection component detects that the blister boxes 90 in the second linear guide groove 67 are stacked to the target quantity, the first driving unit 682 drives the material shifting seat 681 to move forward quickly, so that the material shifting rod 684 pushes the stacked blister boxes 90 whose quantity has been counted forward quickly onto the platform 80. Finally, the third driving unit 82 pushes the stacked blister boxes 90 on the platform 80 to the third conveyor belt 81, and the third conveyor belt 81 transports the stacked blister boxes 9090 to the next station.
