[0028] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0030] This embodiment discloses a propellant loading mechanism for loading propellant column 100, such as... Figures 1-6As shown, it includes: a support 1, on which a medicine column filling assembly 3, a fall protection assembly 5 and a housing positioning assembly 4 are arranged sequentially in the vertical direction; the medicine column filling assembly 3 is driven by a linear module 2 to move linearly along a preset path.
[0031] The fall protection component 5 includes a fifth cylinder 51, a parallel third guide rail 54, and a fixed tray 56 mounted on the bracket 1. The fifth cylinder 51 is fixed to a movable tray 53 corresponding to the fixed tray 56 via a tray mounting plate 52. The tray mounting plate 52 slides with the third guide rail 54 via a fourth slider 55 to form a linear guide constraint.
[0032] The drug cartridge loading assembly 3 is used to hold the drug cartridge 100, and the housing positioning assembly 4 is used to limit the housing of the drug cartridge 100.
[0033] It should be noted that during the process of the fifth cylinder 51 driving the tray mounting plate 52 to move the moving tray 53, the third guide rail 54 can restrict the movement path of the moving tray 53 with the help of the fourth slider 55. When the medicine column filling assembly 3 clamps the medicine column 100 and moves it to the housing above the housing where the housing positioning assembly 4 is limited, after the medicine column filling assembly 3 corrects the position of the medicine column 100 according to the position of the housing, it pushes the medicine column 100 into the housing. After that, the fifth cylinder 51 drives the moving tray 53 to move to the fixed tray 56 and docks with it to form a protective layer at the bottom of the medicine column 100, which can be used to catch the medicine column 100 that is accidentally dropped and prevent it from falling to the ground from a high drop.
[0034] like Figure 5 As shown, the fixed tray 56 and the movable tray 53 are provided with anti-static rubber on the side of the cartridge filling assembly 3.
[0035] like Figure 1 and Figure 2 As shown, when the movable tray 53 and the fixed tray 56 are docked, their vertical projections completely cover the housing positioning component 4.
[0036] like Figures 1-6 As shown, the fifth cylinder 51 is a rodless cylinder, designed to save installation space.
[0037] like Figure 2 As shown, the linear module 2 includes a motor 21, a drive shaft 22, and a protective housing 23. The motor 21 drives the drive shaft 22 through a synchronous pulley and a synchronous belt. Both ends of the drive shaft 22 are provided with synchronous pulleys for mounting the synchronous belt that drives the drug cartridge filling assembly 3 to move. The bracket 1 is provided with a matching synchronous pulley on the other side opposite to the drive shaft 22. The protective housing 12 is used to cover the synchronous pulley and the synchronous belt.
[0038] It should be noted that the linear module 2 is driven by the motor 21, which drives the transmission shaft 22 to rotate, and the transmission shaft 22 forms synchronous motion at both ends. Then, the first slider 31 connected to the synchronous belt drives the drug cartridge filling assembly 3 to move.
[0039] like Figure 4 As shown, the drug loading assembly 3 includes a protective cover 32 with a first slider 31 for connecting the linear module 2. The cavity inside the protective cover 32 is provided with a fixing frame 33. A first cylinder 331 and a linear bearing 334 are mounted on the fixing frame 33. The output end of the first cylinder 331 is provided with a movable mounting plate 332. An extension rod 333 is provided inside the linear bearing 334. The extension rod 333 is used to limit the movable mounting plate 332. A second cylinder 34 is provided on the movable mounting plate 332.
[0040] It should be noted that when the first cylinder 331 drives the movable mounting plate 332 to move, the extension rod 333 can move along with the movable mounting plate 332 and play a role in restricting its movement path.
[0041] like Figure 3 As shown, a fixing plate 35 is fixedly connected to the output end of the second cylinder 34. A third cylinder 351 and a first guide rail 353 are installed at the bottom of the fixing plate 35. The third cylinder 351 is externally connected to a mounting bracket 352. The mounting bracket 352 slides with the first guide rail 353 through a second slider 354 to form a linear guiding constraint.
[0042] It should be noted that when the third cylinder 351 drives the mounting bracket 352 to move, the first guide rail 353 can restrict its movement path with the help of the second slider 354. Furthermore, the movement of the mounting bracket 352 can drive the robotic arm 37 to adjust its position, thereby adjusting the position of the dart cartridge 100 according to the position of the housing.
[0043] like Figure 3 As shown, the bottom of the mounting frame 352 is provided with a clamping cylinder 36 and a robot arm 37. The output end of the clamping cylinder 36 is fixedly connected to a connecting plate 361, and the tail end of the connecting plate 361 is fixedly connected to a pressure plate 362. The pressure plate 362 is used to press the medicine column 100 held by the robot arm 37.
[0044] It should be noted that the clamping cylinder 36 drives the pressure plate 362 to move and abut against the top of the drug column 100 held by the robotic arm 37. During the process of filling the drug column 100 into the housing, the drug column 100 can be further pushed into the housing.
[0045] like Figure 6As shown, the housing positioning assembly 4 includes a support frame 41 and a second guide rail 46 mounted on the bracket 1. A fourth cylinder 42 is provided in the cavity of the support frame 41. The fourth cylinder 42 is fixed to a mounting plate 44 by a mounting block 43. Positioning plates 45 are symmetrically provided on both sides of the mounting plate 44. The bottom of the mounting plate 44 slides with the second guide rail 46 through a third slider 47 to form a linear guiding constraint.
[0046] It should be noted that when the fourth cylinder 42 moves the mounting plate 44 and the positioning plate 45 via the mounting block 43, the second guide rail 46 limits its movement path with the help of the third slider 47.
[0047] like Figure 6 As shown, the housing positioning assembly 4 has two sets, which limit the position of the drug cartridge 100 by positioning plates 45. It should be noted that the positioning plates 45 of the two sets of housing positioning assemblies 4 are close to each other to clamp the housing of the drug cartridge 100.
[0048] Working principle: The housing is held by the housing positioning component 4, and the drug cartridge 100 is held by the drug cartridge filling component 3. Driven by the linear module 2, the drug cartridge filling component 3 moves to the top of the housing positioning component 4. With the help of the adjustment of the third cylinder 351, the drug cartridge 100 is aligned with the housing. Then, the pressing cylinder 36 drives the pressure plate 362 to push the drug cartridge 100 into the housing. After that, the second cylinder 34 drives the robot arm 37 to move up to the top of the fall protection component 5. The fifth cylinder 51 drives the moving tray 53 to dock with the fixed tray 56 to form a protective layer at the bottom of the drug cartridge 100, which can be used to catch the drug cartridge 100 that is accidentally dropped and prevent it from falling to the ground from a high drop.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
