When the driving roller 19 rotates, the supporting rods 18 are driven to rotate. When the supporting rods 18 rotate, the lower rotating ring 13 is driven to rotate.

[0026] In a further embodiment, the lower conveying assembly includes an upper rotating ring 12 rotatably mounted in the top cover 4, a plurality of connecting rods are fixedly mounted on the driving roller 19, and one end of the plurality of connecting rods away from the driving roller 19 is fixedly mounted on the upper rotating ring 12, a plurality of mounting rods are fixedly mounted on the lower part of the upper rotating ring 12, and a plurality of upper positioning units are respectively arranged on the corresponding mounting rods; When the servo motor 11 is started, the driving roller 19 is driven to rotate. When the driving roller 19 rotates, the multiple connecting rods are driven to rotate. When the multiple connecting rods rotate, the upper rotating ring 12 is driven to rotate, thereby driving the multiple mounting rods to rotate. A control panel 6 is provided on the mounting base 1 , and the control panel 6 is used to control the rotation speed of the servo motor 11 , so as to adjust the installation speed of the fire extinguisher handle 32 according to actual production requirements.

[0027] Example 3: Reference Figure 2-Figure 4 as well as Figure 8-Figure 14 , the technical solution of this embodiment is different from that of the second embodiment in that: a rotating mechanism is installed between the lower rotating ring 13 and the mounting base 1, the rotating mechanism includes a plurality of rotating shafts 20 rotatably mounted on the upper part of the lower rotating ring 13, and each lower positioning unit is arranged on a corresponding rotating shaft 20, a positioning gear ring 14 is fixedly mounted on the mounting base 1 through a plurality of supporting columns 7, a driven gear 15 is fixedly mounted on each rotating shaft 20, and each driven gear 15 is meshed with the positioning gear ring 14; When the lower rotating ring 13 rotates, it will drive the multiple rotating shafts 20 thereon to rotate in a circle around the driving roller 19. When the rotating shaft 20 rotates, the driven gear 15 thereon is in contact and meshing with the positioning gear ring 14, so that the driven gear 15 will move outside the positioning gear ring 14 during the circular rotation, and will rotate on its own due to the meshing during the rotation and walking process, so that the rotating shaft 20 can rotate in a circle and at the same time rotate on its own.

[0028] In a further embodiment, each lower positioning unit includes a positioning assembly and a discharge assembly for fixing the outer cylinder 10 of the fire extinguisher, and the lower positioning unit includes a positioning sleeve 16, and the positioning sleeve 16 is fixedly mounted on the upper part of the rotating shaft 20; As can be seen from the above, the positioning sleeve 16 is fixed to the upper part of the rotating shaft 20, so that when the servo motor 11 is started, it will drive the positioning sleeve 16 to rotate in a circle, and rotate itself while rotating in a circle; The positioning assembly includes a fixed box 27 fixedly installed in the positioning sleeve 16, a lifting plate 29 is slidably installed in the fixed box 27, a plurality of lifting springs 30 are fixedly installed between the lifting plate 29 and the top wall of the fixed box 27, air is filled between the lower part of the lifting plate 29 and the fixed box 27, a lifting column 28 is slidably installed between the lifting plate 29 and the fixed box 27, and a bearing plate 26 matching the outer cylinder 10 of the fire extinguisher is fixedly installed on the upper part of the lifting column 28, a plurality of conduction tubes 25 are fixedly connected to the fixed box 27, and a piston rod is slidably installed in each conduction tube 25, and a positioning clamping plate 24 is fixedly installed on each piston rod; When installing the outer cylinder 10 of the fire extinguisher, the outer cylinder 10 of the fire extinguisher can be placed on the carrier plate 26 in the positioning sleeve 16, and the carrier plate 26 is pressed downward. When the carrier plate 26 moves downward, it will drive the lifting column 28 to move downward. When the lifting column 28 moves downward, it will drive the lifting plate 29 to move downward. When the lifting plate 29 moves downward, it will squeeze the air in the fixed box 27, so that the air in the fixed box 27 will be pressed into the multiple transmission tubes 25. When the air in the multiple transmission tubes 25 increases, the piston rod will be pushed to move. When the piston rod moves, it will drive the corresponding positioning clamping plate 24 to move. When the positioning clamping plate 24 moves, it will be pressed and fitted with the side of the outer cylinder 10 of the fire extinguisher. The multiple positioning clamping plates 24 cooperate with each other to squeeze and position the outer cylinder 10 of the fire extinguisher, and complete the automatic positioning of the outer cylinder 10 of the fire extinguisher. That is, the installation of the fire extinguisher outer cylinder 10 only requires placing it into the positioning sleeve 16 and pressing it down, and the fire extinguisher outer cylinder 10 can be automatically squeezed and positioned with the cooperation of the positioning component, and the positioning speed is faster, which can effectively improve the positioning stability of the fire extinguisher handle 32.

[0029] The unloading assembly includes a rotating card plate 22 rotatably mounted on a lifting column 28, a communication opening 21 is provided in the positioning sleeve 16, and the communication opening 21 cooperates with the rotating card plate 22, and a limit card plate 23 cooperating with the rotating card plate 22 is fixedly mounted on the outside of the positioning sleeve 16; When the fire extinguisher outer cylinder 10 is pressed down to drive the lifting column 28 to move downward, the rotating card plate 22 will be driven to move downward. When the fire extinguisher outer cylinder 10 is positioned, the rotating card plate 22 can be rotated to drive it to rotate in the connecting opening 21, and the rotating card plate 22 is rotated to the lower part of the limiting card plate 23. At this time, the limiting card plate 23 will block and limit the rotating card plate 22, so that the rotating card plate 22 cannot move up and reset. A trigger rod 17 matched with the rotating clamping plate 22 is fixedly mounted on the mounting base 1, and the triggering rod 17 is located at the front of the unloading work area 2. When the outer cylinder 10 of the fire extinguisher rotates to the triggering rod 17 along with the positioning sleeve 16, the positioning sleeve 16 will contact and squeeze the triggering rod 17. At this time, the rotating clamping plate 22 on the positioning sleeve 16 will rotate back to the communicating opening 21 under the squeezing of the triggering rod 17, thereby releasing the limiting blocking effect of the limiting clamping plate 23 on the rotating clamping plate 22. When the lifting plate 29 moves downward, the plurality of lifting springs 30 will be stretched to extend them, and when the rotating clamping plate 22 is released from the limit, the plurality of lifting springs 30 will be unobstructed and automatically shrink and reset, thereby driving the lifting plate 29 to move upward and reset. When the lifting plate 29 moves upward and reset, the air in the plurality of conduction tubes 25 will be drawn back into the fixed box 27. At this time, the positioning clamp 24 will automatically reset, thereby releasing the squeezing positioning of the fire extinguisher outer cylinder 10. At the same time, when the lifting plate 29 moves upward, it will drive the carrying plate 26 to move upward through the lifting column 28. When the carrying plate 26 moves upward, it will push the fire extinguisher outer cylinder 10 to move upward, that is, the fire extinguisher outer cylinder 10 will pop up, thereby completing the automatic pop-up unloading of the fire extinguisher outer cylinder 10, and the fire extinguisher outer cylinder 10 after unloading can be transported and unloaded through the unloading work area 2.

[0030] In a further embodiment, the upper positioning unit includes a fixed frame 31 fixedly mounted at the lower part of the mounting rod, a sliding plate 34 is slidably mounted in the fixed frame 31, and two extrusion springs 35 are fixedly mounted between the sliding plate 34 and the fixed frame 31, and a locking mechanism is provided at the lower part of the sliding plate 34; The clamping mechanism includes two clamping extrusion frames 33 slidably mounted on the lower part of the sliding plate 34, and an extrusion spring 35 is fixedly mounted between the two clamping extrusion frames 33. The fire extinguisher handle 32 is provided with two clamping grooves for installation, and the two clamping grooves are respectively matched with the two clamping extrusion frames 33. When the fire extinguisher outer cylinder 10 rotates to the loading area 2 3, the fire extinguisher handle 32 can be installed. First, the sliding plate 34 is pushed up to squeeze the squeezing spring 35, and then the two engaging grooves on the fire extinguisher handle 32 are engaged with the two engaging squeezing frames 33 to complete the positioning of the fire extinguisher handle 32. When the fire extinguisher outer cylinder 10 rotates to the position directly below the fire extinguisher handle 32, the sliding plate 34 is released to release the squeezing spring 35. At this time, the squeezing spring 35 automatically stretches and resets to push the two engaging squeezing frames 33 downward. The two engaging squeezing frames 33 drive the fire extinguisher handle 32 downward, so that the fire extinguisher handle 32 moves downward and is initially engaged with the rotating fire extinguisher outer cylinder 10. After the fire extinguisher handle 32 is installed, its upper part will rotate with the rotation of the upper rotating ring 12 and the fixed frame 31, and the fire extinguisher outer cylinder 10 will rotate with the rotation of the lower rotating ring 13. Since the upper rotating ring 12 and the lower rotating ring 13 are driven by the same servo motor 11, the fire extinguisher outer cylinder 10 and the fire extinguisher handle 32 will rotate synchronously. The fire extinguisher outer cylinder 10 will rotate while rotating in a circle, while the fire extinguisher handle 32 cannot rotate while rotating in a circle, and the compression spring 35 will apply downward pressure to the fire extinguisher handle 32 while rotating. Under the action of the rotation of the fire extinguisher outer cylinder 10 and the downward pressure of the fire extinguisher handle 32, the fire extinguisher handle 32 and the fire extinguisher outer cylinder 10 can be screwed and fixed, and the fire extinguisher handle 32 can be automatically installed.

After the fire extinguisher handle 32 is installed, a complete fire extinguisher is formed. When the fire extinguisher is transported to the unloading assembly, it will automatically pop out under the action of the unloading assembly to complete the unloading, and then be transported to the unloading work area 2. The fire extinguisher is taken out and placed in the unloading work area 2 for further transportation, completing the entire installation process; S6, after the first fire extinguisher outer cylinder 10 leaves the loading work area 9, the second lower positioning unit will be sequentially transported to the loading work area 9 to load and install the second fire extinguisher outer cylinder 10. When the second fire extinguisher outer cylinder 10 continues to be transported, steps S3-S5 are repeated to complete the automated installation of the second fire extinguisher handle 32; S7. Similarly, repeat step S6 to sequentially complete the automated installation of multiple fire extinguisher handles 32.
