As shown in fig. 1 and 9, in addition to the above-mentioned embodiments, an oscillating mechanism 8 for oscillating the plastic ampoules 11 arranged in series to fill the heads with the liquid medicine is arranged upstream of the head and tail detection station.

The invention has the specific working principle that:

as shown in fig. 1, the plastic ampoules 11 in a row enter the bottle feeding mesh belt 1 through a connecting line or manual placement, the bottle feeding mesh belt 1 conveys the plastic ampoules 11 in a row forwards, the accelerating mesh belt 2 pulls the plastic ampoules 11 in a row apart by a distance (the accelerating mesh belt is very fast and is about 2 times of the detecting mesh belt), then the detecting mesh belt is waited for, and when the position of the detecting mesh belt is proper, the accelerating mesh belt conveys the plastic ampoules in a row to a station of the detecting mesh belt.

Pushing the plastic ampoules in the row to convey forwards by a push rod arranged on the detection mesh belt; then, the bottle body and the bottle body parting line are detected by the middle bottle body detection station 4 and the middle bottle body detection station 4, and the relative positions of the bottle body, the bottle body parting line and the detection electrode are shown in fig. 3.

As shown in fig. 3, in the same station of the body detection, a plurality of groups of detection electrodes are arranged, including a body detection emission probe 12 and a body detection receiving electrode 13, and the emission probes of the detection electrodes are all connected in an equipotential manner, and the receiving electrodes are also connected in an equipotential manner, and the distance between each group of detection electrodes is greater than the length of the plastic ampoules in the row. The plastic ampoules in the row can not be contacted with the two groups of detection electrodes one by one, and the aim of detecting a plurality of plastic ampoules in the row one by one high-voltage power supply is achieved.

Then, through the bottle body detection stations 5 at the two sides, the shapes and the relative positions of the detection electrodes of the bottle body detection stations 5 at the two sides are the same as those of the middle bottle body detection station 4, and the difference is that the middle bottle body detection station 4 detects the ampoules in the middle of the plastic ampoules in the row, and the bottle body detection stations 5 at the two sides detect the ampoules at the two sides of the plastic ampoules in the row.

Then, the lower surfaces of the plastic ampoules 11 in the row are turned over through a first turning mechanism 6; the blades of the turnover wheel of the first turnover mechanism 6 are parallel to each other, the plastic ampoules in the row are clamped in the middle, and when the plastic ampoules in the row are prevented from being turned over, the plastic ampoules in the row are shaken, so that unsmooth operation is caused. After overturning, the bottle body detection device sequentially passes through the next two-side bottle body detection station 5 and the middle bottle body detection station 4 for detection.

Then the plastic ampoules 11 in the row are pushed to a second detection mesh belt 18 by a bottle pushing mechanism 7; the second foraminous sensing belt 18 is disposed at 90 degrees to the first.

The structure of the bottle pushing mechanism 7 is shown in fig. 5-6, a servo motor 71 drives a synchronous belt 72 to move, and a push rod 73 is arranged on the synchronous belt 72 to move synchronously; the push rod 73 pushes the row of plastic ampoules 11 on the first inspection mesh belt 3 to the second inspection mesh belt 18.

After the plastic ampoules 11 enter the second detection mesh belt 18, the oscillating mechanism 8 on the second detection mesh belt 18 oscillates the plastic ampoules 11 to fill the head with the liquid medicine (the head has a small diameter, and the liquid medicine is difficult to enter when the head is horizontally placed).

The oscillating mechanism 8 is structurally shown in fig. 9, and comprises a synchronous belt 72 for conveying the plastic ampoules 11 in the row to move, a connecting rod 83 is arranged above the synchronous belt 72, one end of the connecting rod 83 is connected with a linear reciprocating mechanism, and a barrier frame capable of pushing the plastic ampoules 11 in the row to swing in a horizontal plane is arranged below the other end of the connecting rod 83; the fence frame consists of a first fence plate 81 and a second fence plate 82; the rows of plastic ampoules 11 are conveyed between a first fence 81 and a second fence 82.

The oscillating mechanism 8 is installed above a synchronous belt 72, push rods 73 are distributed on the synchronous belt 72, the synchronous belt 72 is arranged between second detection mesh belts 18, the plastic ampoules 11 in the row move on the second detection mesh belts 18, the synchronous belt 72 drives the plastic ampoules 11 in the row to move forwards through the push rods 73, a first fence plate 81 and a second fence plate 82 are arranged on two sides of the synchronous belt 72, and the first fence plate 81 and the second fence plate 82 form a fence frame; the linear reciprocating mechanism drives the connecting rod 83 to swing left and right to drive the fence frame to swing left and right, so that the row of plastic ampoules 11 also swing left and right in the forward moving process, liquid medicine oscillates in the row of plastic ampoules, and the liquid medicine can enter the heads of the row of plastic ampoules.

The linear reciprocating mechanism consists of a connecting rod 86, an eccentric shaft 87 and a motor 88; one end of the connecting rod 86 is hinged with the connecting rod 83, and the other end is hinged with the eccentric shaft 87; the eccentric shaft 87 is connected to a motor 88. As shown in fig. 1, the connecting rod 86 is hinged on a vertical hinge shaft of the connecting rod 83, and the other end is hinged on an eccentric shaft 87; when the motor 88 drives the eccentric shaft 87 to rotate, the connecting rod 86 is driven to perform a pushing and pulling motion, so that the connecting rod 83 is driven to swing.

A gap is left between the first grid plate 81 and the second grid plate 82; the gap width is greater than the outer diameter of the push rod 73 on the timing belt 72. Since the push rod 73 needs to push the plastic ampoules in the row to move, a gap for the push rod 73 to move needs to be left between the barrier frames.

In order to improve the pushing stability of the fence frame to the row of plastic ampoules, the first fence plate 81 and the second fence plate 82 are L-shaped in cross section.

In order to increase the stability of the movement of the connecting rod 83, the connecting rod 83 is arranged on a guide rail 84 via a slide 85.
