[0002] In peritoneal dialysis treatment, the dialysate is filled into a drug bag. The drainage device includes a drainage bag and a drainage tube. The drainage bag is in a pre-emptive state. The two are separately manufactured components. The insertion tube of the drug bag must be precisely connected to the opening of the drainage device before use.

[0003] In existing technologies, some products are assembled by inserting the medicine bag tube and the drainage device into the tube before leaving the factory and then packaged. However, this assembly process relies heavily on manual operation, and operators need to apply a lot of external force to complete the insertion. Repeated forceful operation can easily cause work fatigue, indirectly leading to an increase in the defect rate. Another solution uses machine insertion, where the tube is mechanically clamped. After insertion, the medicine bag and drainage device are mostly in a loose state, requiring an additional sorting and sorting process before entering the subsequent packaging process. This not only prolongs the production cycle but also reduces the overall production efficiency. Summary of the Invention

Detailed Implementation

[0017] The technical solutions of the 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, and not all embodiments. It should be understood that this application is not limited to the exemplary embodiments disclosed herein. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0018] like Figure 1-32 As shown, a medical drug bag and drainage device assembly device includes a drug bag transport unit 1, a drug bag docking unit 2, a drainage device transport unit 3, a drainage device docking unit 4, and a conveyor belt 5; the drug bag transport unit 1 and the drug bag docking unit 2 are located on one side of the conveyor belt 5, the drainage device transport unit 3 is located on the other side of the conveyor belt 5, and the drainage device docking unit 4 is located above the conveyor belt 5; the drug bag transport unit 1 is located downstream of the conveyor belt 5, and the drug bag docking unit 2, the drainage device transport unit 3, and the drainage device docking unit 4 are located upstream of the conveyor belt 5.

[0019] The liquid medicine bag transfer unit 1 includes several liquid medicine bag transfer mechanisms 10. The liquid medicine bag 6 is placed on the conveyor belt 5. The liquid medicine bag transfer mechanism 10 clamps the liquid medicine bag insertion tube 62 and transfers the liquid medicine bag 6 to the liquid medicine bag docking unit 2. The liquid medicine bag insertion tube 62 faces upward.

[0020] The liquid medicine bag docking unit 2 includes several liquid medicine bag clamping mechanisms 20; when the liquid medicine bag 6 arrives at the liquid medicine bag docking unit 2, the liquid medicine bag clamping mechanism 20 clamps the liquid medicine bag insertion tube 62, and the liquid medicine bag handover mechanism 10 releases the liquid medicine bag insertion tube 62 and resets to return to the liquid medicine bag transmission unit 1.

[0021] The drainage device transmission unit 3 includes several drainage device worktables 30, and the drainage device 7 is placed on the drainage device worktables 30.

[0022] The drainage device docking unit 4 includes a rotating moving mechanism 40b and a drainage device clamping mechanism 40. The drainage device clamping mechanism 40 clamps the opening of the drainage tube 72. The rotating moving mechanism 40b rotates the drainage device clamping mechanism 40 by 90° so that the opening of the drainage tube 72 faces downward. The rotating moving mechanism 40b translates the drainage device clamping mechanism 40 to above the medicine bag docking unit 2. The rotating moving mechanism 40b descends, and the opening of the drainage tube 72 docks with the medicine bag insertion tube 62 in the vertical direction.

[0023] Specifically, such as Figure 2-12 As shown, the liquid medicine bag transfer unit 1 transfers the liquid medicine bag 6 to the liquid medicine bag docking unit 2, as follows: Figure 13-32 As shown, the drainage device docking unit 4 clamps the drainage device 7 from the drainage device transmission unit 3, rotates and moves it above the medicine bag docking unit 2, aligns the opening of the drainage tube 72 with the medicine bag insertion tube 62, and moves the drainage device docking unit 4 downward to realize the insertion and assembly of the opening of the drainage tube 72 and the medicine bag insertion tube 62.

[0024] A medical liquid bag and drainage device assembly device, in which the liquid bag transmission unit 1, the liquid bag docking unit 2 and the conveyor belt 5 cooperate to maintain the original spatial posture of the liquid bag 6 during the movement of the liquid bag insertion tube 62, avoiding the bag body distortion caused by traditional clamps; after the insertion is completed, the liquid bag 6 can move to the next station in its original state, eliminating the step of manual shaping and improving the continuity of the process.

[0025] The drainage device workbench 30 pre-fixes the positions of the drainage bag 71 and the drainage tube 72. The drainage device docking unit 4 clamps the drainage bag 71 and the drainage tube 72, maintaining their stable shape during movement. During the clamping of the medicine bag 6, the medicine bag insertion tube 62 always faces upward. After the drainage device docking unit 4 is flipped, the opening of the drainage tube 72 faces downward. The vertical state of the medicine bag insertion tube 62 and the vertical state of the opening of the drainage tube 72 form a natural docking angle, allowing for quick insertion without manual adjustment, greatly improving the ease of operation and docking success rate.

[0026] like Figure 2-11As shown, in this embodiment, the medicine bag transfer mechanism 10 includes a first cylinder 110, a first fixed clamp seat 120, a first fixed clamp 130, a first guide rail 140, a first movable clamp seat 150, a first cylinder clamp 160, and a first support 170; several first fixed clamps 130 are fixed on the first fixed clamp seat 120, the first cylinder 110 is connected to the first fixed clamp seat 120, and the first cylinder 110 is fixed on the first support 170; several first cylinder clamps 160 are fixed on the first movable clamp seat 150, the first movable clamp seat 150 moves on the first guide rail 140, the first guide rail 140 is located on one side of the conveyor belt 5 and fixed on the first support 170; when the first cylinder 110 extends, the position of the first fixed clamp 130 is aligned with the initial position of the first cylinder clamp 160.

[0027] Specifically, the first fixing clamp 130 is a fixing clamp that initially fixes the medicine bag insertion tube 62. The clamping part of the first fixing clamp 130 has a semi-circular groove structure, which holds the medicine bag insertion tube 62 in place. Three first fixing clamps 130 are mounted on a first fixing fixture seat 120. Each first fixing fixture seat 120 is connected to a first cylinder 110. The two first cylinders 110 move synchronously, driving the first fixing fixture seat 120 to move.

[0028] The first cylinder clamp 160 can be pneumatically controlled to open and close, and the first movable clamp seat 150 is equipped with six first cylinder clamps 160. The conveyor belt 5 is designed to be at the same height as the first guide rail 140 to ensure that the medicine bag body 61 remains undeformed when the first cylinder clamp 160 clamps the insertion tube. After the insertion of the medicine bag insertion tube 62 into the drain 7 is completed, the first cylinder clamp 160 moves in the return direction on the first guide rail 140, and the medicine bag 6 and the drain 7 continue to move forward to the next station.

[0029] The filled medicine bag 6 is placed flat on the conveyor belt 5, with the medicine bag tube 62 facing upwards and embedded in the first fixing clamp 130. This step can be achieved by an operator manually aligning the medicine bag tube 62 with the first fixing clamp 130 and embedding it; or by the robotic arm or special clamp of the filling machine grasping the medicine bag 6 and guiding the tube to precisely align with the first fixing clamp 130 using a visual positioning system.

[0030] The specific working principle of the medicine bag transfer mechanism 10 is as follows: The initial position of the first cylinder clamp 160 is aligned with the first fixed clamp 130. The first cylinder clamp 160 clamps the medicine bag tube 62. The first cylinder 110 drives the first fixed clamp 130 to retract, releasing the medicine bag tube 62. The first cylinder clamp 160 moves along the first guide rail 140 to the medicine bag docking unit 2. After the medicine bag clamping mechanism 20 clamps the medicine bag tube 62, the first cylinder clamp 160 releases and returns, aligning with the first fixed clamp 130 again. This process is repeated, and the first cylinder clamp 160 periodically removes the medicine bag tube 62 from the first fixed clamp 130 and transfers it to the medicine bag docking unit 2. During the transfer process, the medicine bag tube 62 always faces upward.

[0031] like Figure 2-4 As shown in Figures 9-13, in this embodiment, the liquid bag clamping mechanism 20 includes: a second cylinder clamp 210, a second guide rail 220, a translation bracket 230, and a second bracket 240. The second bracket 240 is provided with second guide rails 220 at both ends. The second guide rails 220 are arranged perpendicular to the conveyor belt 5. The translation bracket 230 moves on the second guide rails 220. Several second cylinder clamps 210 are fixed on the translation bracket 230. When the translation bracket 230 moves close to the conveyor belt 5, the position of the second cylinder clamp 210 is aligned with the end position of the first cylinder clamp 160.

[0032] Specifically, the second cylinder clamp 210 can be opened and closed pneumatically, and the translation bracket 230 is equipped with six second cylinder clamps 210. Since the insertion of the medicine bag insertion tube 62 and the drainage tube 72 is required at this workstation, the second cylinder clamp 210 will block the rotation of the drainage device 7. Therefore, after the insertion is completed, the second cylinder clamp 210 moves away from the conveyor belt 5 under the drive of the translation bracket 230.

[0033] The specific working principle of the medicine bag clamping mechanism 20 is as follows: The first cylinder clamp 160 clamps the medicine bag insertion tube 62 and aligns it with the second cylinder clamp 210. The second cylinder clamp 210 clamps the medicine bag insertion tube 62. The second clamping mechanism opens and moves away from the medicine bag insertion tube 62. After the medicine bag insertion tube 62 is connected to the opening of the drainage tube 72, the second cylinder clamp 210 opens. The medicine bag 6 and the drainage device 7 are transferred to the next station through the conveyor belt 5 for packaging.

[0034] like Figure 24 and 25As shown, in this embodiment, the drainage device workbench 30 includes a third frame 310, a tray 320, a positioning mechanism 330, and a limiting block 340. The tray 320 is located on the third frame 310. The upper part of the tray 320 is provided with the positioning mechanism 330, which fixes the opening of the drainage tube 72. Several limiting blocks 340 are connected to the circumferential surface of the tray 320. The tray 320 is located below the drainage device clamping mechanism 40.

[0035] Specifically, the drainage device 7 includes a drainage bag 71 and a drainage tube 72. The drainage device 7 is fed onto the drainage device workbench 30, the drainage bag 71 is placed flat on the tray 320, the drainage tube 72 is fixed by the positioning mechanism 330, and the drainage device clamping mechanism 40 clamps the drainage device 7 from the drainage device workbench 30.

[0036] like Figure 24 and 25 As shown, in this embodiment, the positioning mechanism 330 includes a drainage device mounting base 331, an air pipe connector 332, and an air nozzle 333. The air pipe connector 332 and the air nozzle 333 are disposed on the drainage device mounting base 331, which is located on the upper part of the support plate 320. The opening of the drainage tube 72 is connected to the air nozzle 333.

[0037] Specifically, the positioning mechanism 330 is used to fix the drainage tube 72. Since the drainage bag 71 is shipped in empty packaging, the plastic material of the bag may stick together during the subsequent high-temperature sterilization process, so a small amount of gas needs to be injected into the empty bag. In operation, the opening of the drainage tube 72 is inserted into the air nozzle 333. Simultaneously, the other end of the drainage device mounting base 331 is equipped with an air pipe connector 332, which can be connected to an air pump to inflate the bag. A limiting block 340 is provided on the circumference of the tray 320 to facilitate fixing the position of the drainage bag 71 when it is laid flat. Furthermore, a slot is provided at the lower end of the tray 320, allowing for easy observation of the shape of the drainage device 7 during the tray 320's rotation.

[0038] like Figure 29 and 30 As shown, in this embodiment, the drainage device workbench 30 is connected to a moving mechanism 30b; the moving mechanism 30b moves the drainage device workbench 30 below the drainage device clamping mechanism 40.

[0039] Specifically, the drainer 7 is fixed to the drainer worktable 30 at a location away from the drainer docking unit 4. After fixing, the moving mechanism 30b moves the drainer worktable 30 below the drainer clamping mechanism 40. The fixing can be done manually or automatically with the help of other mechanical equipment.

[0040] like Figure 29 and 30As shown, in this embodiment, the drainage device workbench 30 is provided with two sets, including a first set of drainage device workbench 30-1 and a second set of drainage device workbench 30-2; the moving mechanism 30b includes a first servo screw module 301, a second cylinder 302, a first synchronous pulley 303, a first synchronous belt 304, a third guide rail 305, a first transmission rod 306, a second transmission rod 307 and a third frame 310; the first servo screw module 301 moves along the Y-axis direction and the second cylinder 302 moves along the Z-axis direction.

[0041] The third frame 310 is provided with third guide rails 305 at both ends, and a first synchronous pulley 303 is provided on the outer side of the third guide rail 305. A first synchronous belt 304 is connected to the first synchronous pulley 303. The lower end of the first set of drainage device worktables 30-1 is connected to the second cylinder 302. The first transmission rod 306 connects the second cylinder 302 to the upward movement of the first synchronous belt 304. The first servo screw module 301 is connected to the lower part of the first set of drainage device worktables 30-1. The second transmission rod 307 connects the second set of drainage device worktables 30-2 to the downward movement of the first synchronous belt 304. The first set of drainage device worktables 30-1 slides on the third guide rail 305.

[0042] Specifically, the three drainer worktables 30 are arranged as a group, and the moving mechanism 30b alternately transports each group of drainer worktables 30 to the drainer clamping mechanism 40. Dual-station feeding improves production efficiency.

[0043] The first set of drainage device worktables 30-1 is connected to the first servo screw module 301, driving the first set of drainage device worktables 30-1 to move along the Y-axis. The first set of drainage device worktables 30-1 is connected to the second cylinder 302, which drives the first set of drainage device worktables 30-1 to move along the Z-axis. When the second cylinder 302 extends, the height of the first set of drainage device worktables 30-1 is the same as the height of the second set of drainage device worktables 30-2.

[0044] The first set of drainage device worktables 30-1 is connected to the upward movement of the first synchronous belt 304 via the first transmission rod 306, and the second set of drainage device worktables 30-2 is connected to the downward movement of the first synchronous belt 304 via the second transmission rod 307. Therefore, when the first set of drainage device worktables 30-1 moves in the positive Y-axis direction, the second set of drainage device worktables 30-2 moves in the negative Y-axis direction, realizing the alternation of the first set of drainage device worktables 30-1 and the second set of drainage device worktables 30-2. The second set of drainage device worktables 30-2 is connected to the third guide rail 305 for easy sliding.

[0045] The specific principle of the moving mechanism 30b is as follows: When the second cylinder 302 extends, the first set of drainer worktables 30-1 is located below the drainer clamping mechanism 40, and the drainer clamping mechanism 40 clamps the drainer 7; when the second cylinder 302 retracts, the first servo screw module 301 operates, the first set of drainer worktables 30-1 moves in the negative direction, the second set of drainer worktables 30-2 moves in the positive direction, the first set of drainer worktables 30-1 passes under the second set of drainer worktables 30-2, and the second set of drainer worktables 30-2 moves below the drainer clamping mechanism 40; the first servo screw module 301 operates again, the first set of drainer worktables 30-1 moves in the positive direction, the second set of drainer worktables 30-2 moves in the negative direction, and the first set of drainer worktables 30-1 returns to below the drainer clamping mechanism 40. This process is repeated to achieve the alternation of the first set of drainage device workbench 30-1 and the first set of drainage device workbench 30-1.

[0046] like Figure 26-28 As shown, in this embodiment, the drainage device clamping mechanism 40 includes a fixed plate 410, a third cylinder 420, a fourth cylinder 430, a first push plate 440, a second push plate 450, and a third cylinder clamp 460; the second push plate 450 is an L-shaped plate. The upper part of the fixed plate 410 is connected to the third cylinder clamp 460, which clamps the opening of the drainage tube 72. The lower end face of the fixed plate 410 is connected to the first push plate 440 through the third cylinder 420, and the first push plate 440 moves along the Y-axis. The lower side end face of the fixed plate 410 is connected to the second push plate 450 through the fourth cylinder 430, and the first push plate 440 moves along the Z-axis. The first push plate 440 extends and the second push plate 450 extends to clamp the drainage device 7 bag.

[0047] Specifically, the drainage device clamping mechanism 40 has six parts. The fixing plate 410 serves to install the third cylinder 420, the fourth cylinder 430, and the third cylinder clamp 460. Areas where assembly is not required are left unprotected. Based on this design consideration, the fixing plate 410 adopts an L-shaped structure, which not only saves materials but also facilitates observation of the drainage device 7's shape during the flipping process. Furthermore, the through slot 441 on the first push plate 440 is also designed to facilitate easier observation of the drainage device 7's shape during the flipping process.

[0048] like Figure 13-22As shown, the specific working principle of the drainage device docking unit 4 is as follows: Step S1: The drainage device clamping mechanism 40 matches the drainage device worktable 30. The drainage device clamping mechanism 40 is initially positioned above the drainage device worktable 30. After the drainage device clamping mechanism 40 descends to its position, the third cylinder 420 extends and pushes the first push plate 440 to hold the bottom of the drainage bag 71. Immediately afterwards, the fourth cylinder 430 extends and makes the second push plate 450 abut against the front of the drainage bag 71. At this time, the first push plate 440 and the second push plate 450 work together to form a stable clamp on the drainage bag 71. At the same time, the third cylinder clamp 460 clamps the drainage tube 72 fixed on the positioning mechanism 330. Step S2: The rotating moving mechanism 40b is started and moved, and the traction drainage tube 72 is smoothly dislodged from the positioning mechanism 330. The drainage device 7 flipping mechanism is activated, rotating the drainage device clamping mechanism 40 by 90° so that the opening of the drainage tube 72 faces downward. Finally, the entire drug bag docking unit 2 is moved.

[0049] Step S3: The rotating moving mechanism 40b continues to move downwards, and the opening of the drainage tube 72 connects with the drug bag insertion tube 62.

[0050] Step S4: The drainage device 7 flipping mechanism is activated, rotating the drainage device clamping mechanism 40 90° in the opposite direction, and placing the drainage device 7 stably above the medicine bag body 61. The third cylinder clamp 460 is released.

[0051] Step S5: The rotating moving mechanism 40b drives the drainage device clamping mechanism 40 back above the drainage device worktable 30, and the drainage device clamping mechanism 40 resets.

[0052] like Figure 31 and 32 As shown, in this embodiment, the rotary moving mechanism 40b includes a Y-axis assembly, a second servo screw module 402, a lifting motor 403, a lifting platform 404, a rotating shaft 405, a tilting drive motor 406, and a fourth frame 407.

[0053] The Y-axis assembly is located on the top of the fourth frame 407. The lifting platform 404 is located on the Y-axis assembly. The second servo screw module 402 and the lifting motor 403 are connected below the lifting platform 404. The rotating shaft 405 and the flip drive motor 406 are connected below the second servo screw module 402. The rotating shaft 405 is connected to the drain clamping mechanism 40. The Y-axis assembly drives the drainer clamping mechanism 40 to move along the Y-axis direction, the lifting motor 403 drives the drainer clamping mechanism 40 to move along the Z-axis direction through the lead screw module, and the flipping drive motor 406 drives the drainer clamping mechanism 40 to rotate through the rotating shaft 405.

[0054] Specifically, the rotary moving mechanism 40b drives the drainage device clamping mechanism 40 to move in the Y-axis direction, Z-axis direction, and flipping direction.

[0055] Working principle of the rotary moving mechanism 40b: The rotating shaft 405 is connected to the drainer clamping mechanism 40. The flip drive motor 406 drives the rotating shaft 405, thereby causing the drainer clamping mechanism 40 to flip. The second servo screw module 402 drives the rotating shaft 405 to move in the Z-axis direction, thereby causing the drainer clamping mechanism 40 to move in the Z-axis direction. There are two sets of rotating shafts 405 and flip drive motors 406, each set connecting three drainer clamping mechanisms 40. The second servo screw module 402 drives the two sets of rotating shafts 405 to move synchronously in the Z-axis direction through connecting rods. The Y-axis assembly drives the lifting platform 404 to move. The lifting platform 404 is connected to the rotating shaft 405 through the second servo screw module 402, thereby causing the drainer clamping mechanism 40 to move in the Y-axis direction.

[0056] like Figure 31 and 32 As shown, in this embodiment, the Y-axis assembly includes a second synchronous pulley 4011, a second synchronous belt 4012, a drive shaft 4013, a fourth guide rail 4014, a servo motor 4015, and a slider 4016. The fourth frame 407 has four guide rails 4014 at both ends, arranged in parallel. Each fourth guide rail 4014 has a second synchronous pulley 4011, and the second synchronous belt 4012 is connected to the second synchronous pulley 4011. The drive shaft 4013 is connected between the second synchronous pulleys 4011 on one side of the fourth guide rail 4014. The servo motor 4015 drives the second synchronous belt 4012 to rotate via the drive shaft 4013 and the second synchronous pulleys 4011. The lifting platform 404 is connected to the second synchronous belt 4012 via the slider 4016. The bottom of the slider 4016 is connected to the fourth guide rail 4014. When the second synchronous belt 4012 rotates, the slider 4016 slides on the fourth guide rail 4014.

[0057] Specifically, the Y-axis assembly drives the drainage device clamping mechanism 40 to move in the Y-axis direction.

[0058] The specific working principle of the Y-axis assembly is as follows: the servo motor 4015 drives the second synchronous belt 4012 to rotate, and the lifting platform 404 connected to the second synchronous belt 4012 slides on the fourth guide rail 4014, thereby realizing the movement of the Y-axis direction of the diverter worktable 30.
