The above arrangement can realize the pick-and-place operation of each part, and the operation is simple and easy to realize; wherein the arrangement of the fourth mechanical arm 440 enables the parts to be transferred between the two turntables, and the secondary assembly can be completed during the transfer process, greatly improving the assembly efficiency between each combined part and the cartridge 3000. Among them, after the second mechanical arm 420 places the piston 2000 on the cap 1000, the piston 2000 and the cap 1000 are inserted and form a combined part.

[0056] Regarding the structure of the first turntable 310, in some embodiments, the first turntable 310 comprises a first disc body 311 and a plurality of first fixed assemblies 312 arranged circumferentially on the first disc body 311, and during the rotation of the first disc body 311, the first fixed assemblies 312 pass through the cap receiving station, the piston receiving station and the first discharge station in turn. In use, the piston 2000 is transferred to the first turntable 310 by the second mechanical arm 420, and the assembly of the piston 2000 and the cap 1000 is completed during the placement process.

[0057] The first mechanical arm 410 comprises a first transverse driving member, a first longitudinal driving member and a first suction member. The first transverse driving member is arranged on the rack 100. The output end of the first transverse driving member is connected with the first longitudinal driving member and drives the first longitudinal driving member to move in the second direction.

In other embodiments, the first mechanical arm 410 and the second mechanical arm 420 can be arranged according to the prior art, which is not the important content of the present application, and thus is not described in detail herein.

[0058] In use, in order to improve the smoothness of the sliding between the needle cylinder and the piston 2000, the piston 2000 needs to be oiled. In order to achieve this purpose, the needle cylinder assembling device comprises an oiling assembly 317. During the rotation of the first disc body 311, the first fixed assembly 312 sequentially passes through the cover body receiving station, the piston receiving station, the oiling station and the first discharging station. When the piston 2000 passes through the oiling station, the oiling assembly 317 applies oil to the piston 2000. Specifically, the oiling assembly 317 comprises an oiling member 3171 and an oiling driving member 3172. The oiling driving member 3172 is arranged on the rack 100. The output end of the oiling driving member 3172 is connected with the oiling member 3171 and drives the oiling member 3171 to move close to or away from the axis of the first disc body 311. The oil nozzle of the oiling member 3171 can discharge oil. The oiling member 3171 comprises an automatic oiler or other oiling equipment in the prior art.

[0059] The first fixed assembly 312 comprises a first fixed seat 3121, a rotating shaft 3122 and a fixed disc 3123. The first fixed seat 3121 is fixed to the first disc body 311. The rotating shaft 3122 is rotatably arranged on the first fixed seat 3122 through a bearing 3125. The fixed disc 3123 is arranged on one end of the rotating shaft 3122. The needle cylinder assembling device comprises a rotating driving assembly. The power output end of the rotating driving assembly can drive the rotating shaft 3122 at the oiling station to rotate. The cover body 1000 can be placed on the fixed disc 3123. When the rotating driving assembly drives the rotating shaft 3122 to rotate, the cover body 1000 is driven to rotate, thereby driving the piston 2000 to rotate. During the rotation of the piston 2000, the oiling member 3171 discharges oil, thereby completing the 360° rotation of the piston 2000 and the oiling operation.

[0060] The bearing 3125 is installed in the stepped hole of the first fixing base 3121, and the upper end of the bearing 3125 is clamped and limited by the snap ring 3126.

[0061] Regarding the structure of the rotating driving component, in some embodiments, the rotating driving component comprises a rotating mounting base 313, a first rotating driving component 314 and a second rotating driving component 315. The rotating mounting base 313 is arranged on the rack 100. The first rotating driving component 314 is arranged on the rotating mounting base 313. The output end of the first rotating driving component 314 is connected with the second rotating driving component 315 and can drive the second rotating driving component 315 to move between the meshing position and the separation position. The output end of the second rotating driving component 315 is provided with a driving gear 316. The other end of the rotating shaft 3122 is provided with a driven gear 3124. When the second rotating driving component 315 is located at the meshing position, the driving gear 316 and the driven gear 3124 are meshed, and the second rotating driving component 315 drives the rotating shaft 3122 to rotate to drive the fixed disc 3123 to rotate. The above arrangement can selectively mesh the driving gear 316 and the driven gear 3124, so as to complete the driving of the rotating shaft 3122, and avoid blocking the first fixing component 312 when the second rotating driving component 315 is located at the separation position, so that the combined component on the first fixing component 312 can smoothly move to the next station.

[0062] The fourth mechanical arm 440 comprises a disc changing lifting driving component 441, a disc changing rotating driving component 442 and a disc changing clamping component 443. The disc changing lifting driving component 441 is arranged on the rack 100. The output end of the disc changing lifting driving component 441 is connected with the disc changing rotating driving component 442. The output end of the disc changing rotating driving component 442 is connected with the disc changing clamping component 443. The disc changing lifting driving component 441 and the disc changing rotating driving component 442 jointly drive the disc changing clamping component 443 to move between the first discharging station and the cylinder cover assembling station. In use, when the disc changing clamping component 443 is located at the first discharging station, the combined component is clamped, and then the combined component is pulled out from the fixed disc 3123 during the upward movement of the disc changing lifting driving component 441. After the disc changing clamping component 443 is turned over by 180° under the driving of the disc changing rotating driving component 442, the combined component is moved to the cylinder cover assembling station. During the downward movement of the disc changing lifting driving component 441, the combined component is assembled to the upper end opening of the barrel 3000. The above process not only completes the position transfer of the combined component, but also completes the turning over of the combined component and the assembling process of the combined component and the barrel 3000. One step operation achieves multiple effects, and the assembling efficiency is greatly improved.

[0063] The cover body 1000 is provided with a slot, and the fixed disc 3123 is provided with a plug which can be inserted into the slot.

[0064] In some embodiments, the second rotary table 320 comprises a second disc body 321 and a plurality of second fixing assemblies 322 arranged circumferentially on the second disc body 321, and the second fixing assemblies 322 pass through the cartridge receiving station, the cap assembling station and the second discharging station in sequence during rotation of the second disc body 321. The above arrangement realizes clamping and position transfer of the cartridge 3000, wherein the cap assembling station and the first discharging station are arranged along the first direction at intervals, and the above arrangement makes the action of the third mechanical arm 430 more concise and shortens the moving path of the assembly during movement between the two rotary tables, thereby improving the assembly efficiency.

[0065] In some embodiments, the second fixing assembly 322 comprises a second fixing base 3221, a clamping rod 3222 and an elastic member 3223, the second fixing base 3221 is provided with a receiving groove 3224 with an opening direction away from the axis direction of the second disc body 321, the clamping rod 3222 is provided with two, both of which are rotationally connected to the second fixing base 3221 and respectively located on both sides of the receiving groove 3224, and the two elastic members 3223 respectively apply elastic force to the corresponding clamping rods 3222 to make the ends of the two clamping rods 3222 away from the groove bottom of the receiving groove 3224 close to each other to block the slot opening of the receiving groove 3224. The above arrangement enables the two clamping rods 3222 to close to each other after clamping the cartridge 3000 in the receiving groove 3224 of the second fixing assembly 322, thereby avoiding the cartridge 3000 from being thrown out of the slot opening due to inertia during rotation.

[0066] The upper end opening of the cartridge 3000 is provided with an outwardly extending flange 3100, and in combination with the structure of the cartridge 3000, the structure of the second fixing assembly 322 is arranged, the opening size of the receiving groove 3224 is greater than the diameter of the cartridge 3000 and less than the outer diameter at the flange 3100, the clamping rod 3222 comprises a rod body and a blocking portion 32221 arranged on the rod body, and when the ends of the two clamping rods 3222 away from the groove bottom of the receiving groove 3224 close to each other, the distance between the two blocking portions 32221 is less than the diameter of the cartridge 3000. The above arrangement enables the cartridge 3000 to be hung in the receiving groove 3224 through the flange 3100, and the cartridge 3000 is fixed in the receiving groove 3224 due to clamping of the clamping rod 3222.

[0067] To further fix the barrel 3000, in some embodiments, the blocking part 32221 is provided with a first guide surface 32222 and a second guide surface 32223 at two ends in the radial direction of the second disc body 321, the inclination directions of the first guide surface 32222 and the second guide surface 32223 are opposite, and the first guide surface 32222 is located between the groove bottom of the accommodation groove 3224 and the second guide surface 32223. The above arrangement makes the distance between the two blocking parts 32221 first decrease and then increase along the direction close to the axis of the second disc body 321. This arrangement makes the barrel 3000 directly enter the accommodation groove 3224 by extruding the two second guide surfaces 32223 to make the two clamping rods 3222 separate from each other, and then the barrel 3000 is fixed in the accommodation groove 3224 under the action of the elastic member 3223 after the barrel 3000 enters the accommodation groove 3224. The barrel 3000 can also be directly pulled out by an external force, and in the pulling-out process, the two clamping rods 3222 are separated from each other by extruding the two first guide surfaces 32222, so that the distance between the two blocking parts 32221 is expanded and the barrel 3000 can be moved out. To avoid the barrel 3000 from shaking in the accommodation groove 3224, in some embodiments, when the barrel 3000 is located in the accommodation groove 3224, the side wall of the barrel 3000 abuts against the groove bottom and the second guide surface 32223 of the accommodation groove 3224, so as to clamp the barrel 3000 between the blocking part 32221 and the groove bottom of the accommodation groove 3224. The elastic member 3223 is a spring, the side of the clamping rod 3222 facing the groove wall of the accommodation groove 3224 is provided with a first limiting groove, both sides of the accommodation groove 3224 are provided with a second limiting groove, and the two springs are respectively arranged between the corresponding clamping rod 3222 and the groove wall of the accommodation groove 3224, and the two ends of the spring are respectively located in the corresponding first limiting groove and second limiting groove.

[0068] Specifically, the third mechanical arm 430 comprises a transfer driving member 431 and a transfer clamping member 432, the transfer driving member 431 is arranged on the rack 100, the output end of the transfer driving member 431 is connected with the transfer clamping member 432, and the transfer driving member 431 drives the transfer clamping member 432 to move between the receiving position and the placing position, and the transfer clamping member 432 can clamp the barrel 3000. The above arrangement makes the transfer clamping member 432 clamp the barrel 3000 at the discharge port of the third vibration distribution assembly 230, and then linearly moves the barrel 3000 into the accommodation groove 3224.

[0069] In some embodiments, the needle cylinder assembling device comprises the blocking assembly 500 and the fourth vibration distribution assembly 240 provided on the frame 100, the blocking piece 4000 flows out from the discharge port of the fourth vibration distribution assembly 240, and the blocking assembly 500 blocks the blocking piece 4000 at the lower end opening of the cylinder 3000. The above arrangement enables the blocking piece 4000 to be installed at the lower end opening of the cylinder 3000. In the present embodiment, the second disc body 321 rotates, and the second fixing assembly 322 sequentially passes through the cylinder receiving station, the cylinder cover assembling station, the blocking station and the second discharge station. The blocking piece 4000 is installed at the lower end opening of the cylinder 3000 located at the blocking station.

[0070] Specifically, the blocking assembly 500 comprises a first blocking lifting piece 510, a blocking mounting seat 520, a blocking driving piece 530 and a blocking clamping piece 540. The first blocking lifting piece 510 is provided on the frame 100, the output end of the first blocking lifting piece 510 is connected with the blocking mounting seat 520, and the blocking mounting seat 520 is driven to move between the mounting position and the jacking position. The blocking driving piece 530 is provided on the frame 100, the output end of the blocking driving piece 530 is connected with the blocking clamping piece 540, and the blocking clamping piece 540 is driven to move between the blocking outlet position and the feeding position. The blocking clamping piece 540 comprises a clamping cylinder and two clamping jaws provided on the two output ends of the clamping cylinder, and the clamping cylinder drives the two clamping jaws to approach or move away. The blocking mounting seat 520 located at the mounting position is below the blocking clamping piece 540 located at the feeding position. The above arrangement realizes the receiving and installing actions of the blocking piece 4000, and the operation is simple, only the blocking mounting seat 520 needs to be changed, without the need to change the position of the cylinder 3000, thereby improving the assembling efficiency. In use, the blocking clamping piece 540 clamps the blocking piece 4000 and then moves to the feeding position, and the blocking piece 4000 is placed on the blocking mounting seat 520 at the mounting position, and then the blocking clamping piece 540 moves away. The blocking mounting seat 520 is driven by the first blocking lifting piece 510 to move upward and block the lower end opening of the cylinder 3000 and the blocking piece 4000.

[0071] The two positions of the blocking mounting seat 520 realize the position transfer of the blocking piece 4000 on one hand, and on the other hand, the blocking mounting seat 520 at the mounting position cooperates with the blocking clamping piece 540 below to place the blocking piece 4000 above the blocking mounting seat 520, and then realizes the blocking cooperation between the blocking piece 4000 and the lower end opening of the cylinder 3000 during the upward movement of the blocking mounting seat 520. The movement path of the blocking piece 4000 is short during the whole process, and the ingenious cooperation between the components is realized, thereby improving the assembling efficiency of the blocking piece 4000 and the cylinder 3000.

[0072] The sealing mounting base 520 is equipped with a clamping cylinder. Each of the two output ends of the clamping cylinder is equipped with a gripper. The clamping cylinder drives the two grippers to approach and clamp the sealing component 4000 or to move away from and release the sealing component 4000.

[0073] In some embodiments, the sealing assembly 500 includes a second sealing lifting member 550 and a ballast member 560. The second sealing lifting member 550 is disposed on the frame 100, and its output end is convexly connected to the ballast member 560, driving the ballast member 560 to move between a ballast position and a clearance position. The ballast member 560 in the ballast position presses down on the cover 1000. This arrangement, on the one hand, prevents the sealing member 4000 from pushing the material cylinder 3000 upward during its rising process, thereby improving the installation effect; on the other hand, it also allows the assembly to be better pressed into the upper opening of the material cylinder 3000, that is, the sealing work of the upper and lower ports of the material cylinder 3000 is completed in one action. In addition, in this embodiment, due to the clamping effect of the ballast 560 and the sealing mounting base 520, the second disc body 321 is not subjected to force, thus improving the durability of the second disc body 321. Finally, when the assembly is placed at the upper opening of the material cylinder 3000 by the third robot 430, it does not need to be fully inserted; only the end of the assembly needs to be placed at the upper opening of the material cylinder 3000. This reduces the pressure applied to the material cylinder 3000, thereby preventing the second disc body 321 from being deformed due to excessive force and improving the durability of the second disc body 321.

[0074] In some embodiments, the syringe assembly apparatus further includes an unloading robot 450, which is used to transfer the syringe from the second dispensing position to the next station. It should be noted that the syringe is formed by combining the barrel 3000, the cap 1000, the piston 2000, and the sealing member 4000.

[0075] In some embodiments, each vibratory material distribution component is provided with a housing for protection.
