[0034] This utility model provides a packaging device for water for injection, comprising a conveyor belt 1, a pressing tray 2, a bottle pressing section 3, and a robotic arm 4. Multiple workstations 5 are arranged on the conveyor belt 1 at intervals along its surface. Each workstation 5 contains a fixed packaging box 6. The pressing tray 2 is positioned opposite to the packaging box 6 and is used to place and press a tray 13 into the packaging box 6. The robotic arm 4 is detachably connected to multiple ampoules 7, and carries the ampoules 7 into the tray 13. The bottle pressing section 3 is positioned opposite to the ampoules 7 and is used to press the ampoules 7 firmly onto the tray 13. By driving the multiple workstations 5 via the conveyor belt 1, with each packaging box 6 at each workstation 5 containing a tray 13, and placing the ampoules 7 into the tray 13 via the robotic arm 4, the device achieves rapid ampoule installation. This solves the technical problems of high labor intensity and low work efficiency in the prior art, achieving the technical effect of low labor intensity and high work efficiency.

[0035] In an optional embodiment, the working end of the robotic arm 4 is provided with multiple grippers 8, which are arranged on the same plane, and each gripper 8 is used to grip an ampoule 7.

[0036] In the above embodiment, the robotic arm 4 can be equipped with 100 grippers 8, each gripper 8 can be made of rubber, and each gripper 8 can be opened and closed by air pressure control, so that 100 ampoules 7 can be gripped at the same time by 100 grippers 8 and placed in the tray 13.

The multiple trays 13 are stacked vertically along the surface of the conveyor belt 1. The tray placement part 9 can be detachably connected to the trays 13. The tray placement part 9 can put the bottom tray 13 into the packaging box 6, thereby completing the laying of the trays 13. Each time the tray placement part 9 places a tray 13 into the packaging box 6, the multiple trays 13 fall automatically under the action of gravity, so that the trays 13 can be put into the empty packaging box 6 one by one. After the trays 13 are put in, the packaging box 6 and the trays 13 can be pressed into the packaging box 6 by the pressure plate 202 and the first cylinder 201, so that the trays 13 and the packaging box 6 are firmly connected.

[0041] In an optional embodiment, the tray 9 includes studs 901, connecting rods 902, and a drive unit 903. Multiple studs 901 can be provided, and the multiple studs 901 are spaced apart along the circumference of the tray 13. The end face of each stud 901 abuts against the edge of the tray 13. The multiple studs 901 rotate synchronously, so that the edge of the tray 13 enters the thread of the stud 901 and separates from the stud 901. One end of each stud 901 is connected to a connecting rod 902. The drive unit 903 is connected to the multiple connecting rods 902 respectively. The drive unit 903 is used to drive the multiple studs 901 to rotate synchronously through the multiple connecting rods 902.

[0042] In the above embodiment, four studs 901 and four connecting rods 902 can be provided.

The four studs 901 are all arranged on the same plane and are located below multiple trays 13. The four studs 901 are connected to the edge of the tray 13 through side threads, so that the tray 13 can be fixed by the studs 901. At the same time, the rotation of the studs 901 can cause the tray 13 to fall horizontally and into the packaging box 6. Furthermore, the four connecting rods 902 are rectangularly arranged at the four corners of the tray 13, so that multiple trays 13 can be fixed. The outer sides of the four connecting rods 902 can be connected to the chain at the same time. The drive unit 903 can be a stepper motor. The drive unit 903 can drive the four studs 901 to rotate synchronously through the chain and the four connecting rods 902, so that the trays 13 below can fall into the packaging box 6 one by one.

The bottle pressing plate 302 is connected to the output end of the second cylinder 301, and the second cylinder 301 can drive the bottle pressing plate 302 to press against multiple ampoules 7.

[0044] In the above embodiment, the second cylinder 301 is arranged parallel to the first cylinder 201, and the second cylinder 301 is arranged perpendicular to the surface of the conveyor belt 1. The output end of the second cylinder 301 is provided with a bottle pressing plate 302. The bottle pressing plate 302 extends horizontally into the packaging box 6 and presses against the upper end of multiple ampoules 7. Thus, the second cylinder 301 can drive the bottle pressing plate 302 to press against the multiple ampoules 7, so that the multiple ampoules 7 are firmly connected to the tray 13.

[0045] In an optional embodiment, a sponge layer 303 is provided at one end of the pressure plate 302 away from the second cylinder 301. The sponge layer 303 extends along the surface of the pressure plate 302 and is used to press the multiple ampoules 7 together with the pressure plate 302.

[0046] In the above embodiment, the sponge layer 303 is disposed at one end of the pressure plate 302 near the conveyor belt 1. The pressure plate 302 is connected to 100 ampoules 7. The pressure plate 302 can drive the sponge layer 303 to press firmly on the 100 ampoules 7, so that multiple ampoules 7 can be tightly connected to the tray 13, thereby making the connection between the ampoules 7 and the tray 13 firm.

[0047] In an optional embodiment, a feeding unit 10 is also included. The feeding unit 10 is located near the robotic arm 4 and is provided with a feeding channel. Multiple ampoules 7 move along the feeding channel so that the multiple ampoules 7 are arranged in a matrix within the feeding channel. The robotic arm 4 grabs multiple ampoules 7 at the end of the feeding channel.

[0048] In the above embodiment, the feeding part 10 can be set on the tray 13. The feeding part 10 can be provided with a feeding channel. The feeding channel is set horizontally and has an opening at one end. Ampoules 7 are put in through the opening. Then, multiple ampoules 7 move along the feeding channel and are arranged at the end of the feeding channel, so that multiple ampoules 7 are stacked. Thus, multiple ampoules 7 can be arranged in a ten-row, ten-column manner, so that the robotic arm 4 and the gripper 8 can more smoothly grip the ten-row, ten-column ampoules 7 and the gripping is more accurate.

[0049] In an optional embodiment, the feeding unit 10 includes a conveyor belt 1001, a partition 1002, a gate 1003, and a baffle 1004. Multiple ampoules 7 are mounted on the conveyor belt 1001, and the conveyor belt 1001 carries the multiple ampoules 7 synchronously. The baffle 1004 is mounted on the conveyor belt 1001 and positioned close to the ampoules 7. The baffle 1004 is fixedly mounted and used to restrict the movement direction of the ampoules 7. The gate 1003 is slidably connected to the baffle 1004 and is positioned perpendicular to the movement direction of the ampoules 7. 1003 can move along the direction of approaching and moving away from the ampoule 7, so that the gate 1003 and the baffle 1004 form a material picking space, so that the robotic arm 4 can take away all the ampoules 7 in the material picking space through multiple grippers 8; the partition 1002 is set in the feeding channel, and multiple partitions 1002 are set. The multiple partitions 1002 are spaced apart and parallel along the width direction of the feeding channel. The partitions 1002 are set along the extension direction of the feeding channel.

[0051] The conveyor belt 1001 can be horizontally arranged, bringing the outer ampoules 7 closer to the conveyor belt 1. Multiple partitions 1002 can be arranged above the conveyor belt 1001, with parallel and evenly spaced partitions 1002. The length direction of the partitions 1002 can be parallel to the length direction of the conveyor belt 1001, and only one ampoule 7 can pass between two adjacent partitions 1002, thus arranging the ampoules 7. Furthermore, the baffle 1004 can be U-shaped, and the width of the opening of the baffle 1004 can be... With a width smaller than the bottom, the ampoules 7 can be arranged and conveyed to the bottom of the baffle 1004. The output end of the conveyor belt 1001 can be provided with a platform. The conveyor belt 1001 can transport multiple ampoules 7 to the platform, where they are arranged in ten rows and ten columns with the baffle 1004. Then, the gate 1003 can extend into and out of the feeding channel. After the ampoules 7 are arranged in ten rows and ten columns with the baffle 1004 on the platform, the gate 1003 can extend into the feeding channel to prevent subsequent ampoules 7 from squeezing the ampoules 7 arranged in ten rows and ten columns with the baffle 1004 on the platform.

[0052] The baffle 1004 can be placed on one side of the platform to fix the ampoule 7 in the material picking space. A baffle can be set on both sides of the conveyor belt 1001 along the direction of movement. The width between the two baffles can be set to decrease along the transport direction of the conveyor belt 1001, thereby limiting the movement direction of the ampoule 7 and allowing the ampoule 7 to be better arranged.
