Description

Technical Field

[0001] The present application relates to the technical field of infusion set production, and in particular to a conveying device for infusion set production. Background Art

[0002] As a core medical device for clinical intravenous drug delivery, the infusion set integrates precision components such as a puncture set, infusion hose, drip chamber, flow regulator, and intravenous needle. Leveraging gravity-driven principles and precise flow control technology, it creates a safe and stable drug delivery channel, precisely delivering therapeutic drugs to the human circulatory system. In modern medical device manufacturing, efficient and stable delivery of long infusion set tubing is a key node in maintaining continuous operation on automated production lines, directly impacting product quality and production efficiency.

[0003] In the infusion pump assembly and production process of the prior art, the long tubes of the infusion pump are manually arranged and stacked and placed on the left side inside the storage box. The lifting cylinder drives the suction nozzle to move vertically, adsorbing one end of the long tube of the infusion pump from the inside of the storage box and lifting it to the inside of the two clamps of the finger cylinder. The finger cylinder clamps the end of the long tube of the infusion pump and pulls it to the left through the electric guide rail module to transport the long tube of the infusion pump to the carrier of the assembly machine.

[0004] Regarding the aforementioned technologies, as the finger cylinder pulls the infusion tube along the electric guide rail module, the flexibility of the tube material and the friction between adjacent tubes can easily cause the surrounding tubes to bend and shift, disrupting the original neat stacking. When the suction nozzle contacts the deformed tube, the effective contact area between the tube surface and the suction surface is reduced, often resulting in vacuum failure. This unstable suction problem can directly lead to failures such as tube leakage and mid-line detachment, significantly reducing production line conveyance efficiency and becoming a technical bottleneck restricting automated assembly efficiency and production capacity. Summary of the Invention

[0005] In view of this, the present application provides a conveying device for infusion pump production, which aims to solve the problem of bending and deviation of other long tubes remaining during the conveyance of long tubes of infusion pumps.

[0006] To solve the above technical problems, the present application provides a conveying device for infusion set production, comprising a stand, a storage box for storing long infusion set tubes, and a picking mechanism for transferring the long infusion set tubes;

[0007] The inner wall surface of the storage box is slidably connected to a lifting plate, and the bottom plate of the storage box is fixedly provided with a linear driver, and the execution end of the linear driver is fixedly connected to the lower surface of the lifting plate. The front and rear side walls of the storage box are provided with a driving component 1, and a mounting rod is provided between the two driving components 1. The linear array at the bottom end of the mounting rod is provided with combing teeth for straightening the long infusion tubes stacked inside the storage box. The two ends of the mounting rod are rotatably provided with connecting rings, and the two connecting rings are provided with connecting rods. A pressure rod is fixed between the two connecting rods for pressing one end of the long infusion tube during the combing process.

[0008] By adopting the above technical solution, during the transfer of the long infusion tube, the pressure rod presses the stacked long infusion tubes inside the storage box, thereby preventing the adjacent long infusion tubes inside the storage box from bending and deflecting due to friction during the transfer of the long infusion tube, and preventing the problem of loose adsorption due to insufficient contact area between the hose surface and the suction nozzle when the suction nozzle contacts the bent section. In addition, after the long infusion tube is moved out of the storage box, the driving assembly drives the mounting rod and the combing teeth to move to the right, and the combing teeth are inserted into the stacked long infusion tubes and move to the right to straighten the bent long infusion tubes inside the storage box, thereby avoiding the influence of the material characteristics of the long tubes and the friction between adjacent long tubes, which may cause the long infusion tubes to be messy or even stuck during transportation.

[0009] Optionally, a torsion spring is provided between the interior of the connecting ring and the outer arc surface of the mounting rod.

[0010] By adopting the above technical solution, the torsion spring makes the pressure rod elastically contact with the surface of the long tube of the infusion set, which can avoid deformation or surface scratches of the long tube of the infusion set due to excessive pressure during the combing process, thereby improving product quality.

[0011] Optionally, the outer arc surface of the pressure rod is rotatably connected to a sleeve.

[0012] By adopting the above technical solution, the sleeve rolls and rubs against the surface of the long tube of the infusion set during movement, thereby reducing the friction force on the long tube of the infusion set and reducing the probability of the long tube of the infusion set bending.

[0013] Optionally, a mounting plate is provided on the left side of the interior of the storage box, a partition is provided in a linear array on the upper surface of the mounting plate, and a through hole for avoiding the partition is provided on the lifting plate.

[0014] By adopting the above technical solution, the long tube of the infusion set is limited by the partition, the bending and deviation amplitude of the long tube of the infusion set is reduced, and it is convenient to sort it out.

[0015] Optionally, a slide rail is fixedly provided on the inner bottom surface of the storage box, the mounting plate is fixedly provided on the slider of the slide rail, the motor 2 is fixedly provided on the lower surface of the bottom plate of the storage box, a turntable is fixedly provided on the output shaft of the motor 2, a cam is eccentrically provided on the turntable, a groove plate is fixedly provided on the lower surface of the mounting plate, and the cam is in sliding contact with the inner wall of the groove plate.

[0016] By adopting the above technical solution, the partition is driven to swing back and forth, and the stacked long tubes of the infusion device are vibrated and leveled, ensuring that the suction nozzle can adsorb the long tubes of the infusion device in sequence from the upper layer to the lower layer, reducing clutter.

[0017] Optionally, a groove is provided inside the turntable, the convex shaft is slidably connected to the inside of the groove, the internal thread of the turntable is connected to a screw rod, and the screw rod is rotatably connected to a T-slot provided inside the convex shaft.

[0018] By adopting the above technical solution, the screw is rotated, and the screw drives the cam to move radially relative to the turntable, adjusting the distance between the turntable axis and the cam, thereby controlling the swing amplitude of the grooved plate during rotation.

[0019] Optionally, the drive component 1 includes an L-shaped mounting seat, a transmission wheel and a belt. There are four L-shaped mounting seats and they are respectively arranged on the front and rear side walls of the storage box. The vertical parts of the L-shaped mounting seats are rotatably connected to the transmission wheels via a rotating shaft. The two transmission wheels corresponding to the left and right directions are connected by belt transmission, and the two rotating shafts on the right are connected by a connecting rod transmission. A motor 1 is fixedly installed on the vertical part of the L-shaped mounting seat at the rear right end, and the output shaft of the motor 1 is fixedly connected to the rear end of the connecting rod through a coupling. The mounting rod is fixedly connected to the outer surfaces of the two belts respectively.

[0020] By adopting the above technical solution, the belt drives the mounting rod and the combing teeth to move to the right, and the combing teeth are inserted into the stacked long infusion tubes and move to the right to straighten the bent long infusion tubes inside the storage box.

[0021] Optionally, it also includes a limiting support plate, which has two limiting support plates and is fixedly connected between two L-shaped mounting seats corresponding to the left and right directions. A boss is provided in the middle of each limiting support plate, and the outer surface of the boss is in sliding contact with the inner surface of the belt on the same side.

[0022] By adopting the above technical solution, the boss is used to support the belt, thereby preventing excessive deformation during rotation from affecting the combing effect of the long tube of the infusion set.

[0023] Optionally, the picking mechanism includes an electric guide rail module, a finger cylinder and an adsorption assembly, the electric guide rail module is fixedly arranged at the left end of the stand, the finger cylinder linear array is arranged on the mover seat of the electric guide rail module, the electric guide rail module is used to drive the finger cylinder to move left and right to pull and transport the long tube of the infusion pump, and the adsorption assembly is fixedly connected to the right end of the electric guide rail module, and the adsorption assembly is used to adsorb the long tube of the infusion pump inside the receiving box and transfer it to the two clamps of the finger cylinder.

[0024] By adopting the above technical solution, the two clamping claws of the finger cylinder close to firmly clamp the long tube of the infusion set, and then transfer it through the electric guide rail module to prevent the long tube of the infusion set from falling off during the transfer process.

[0025] Optionally, the adsorption assembly includes a support plate, a lifting cylinder and a suction nozzle, the support plate is fixedly arranged at the right end of the electric guide rail module, the lifting cylinder is fixedly arranged at the middle of the support plate, a connecting plate is provided at the lower end of the push rod of the lifting cylinder, and a buffer plate is slidably connected to the bottom of the connecting plate through a guide rod, and the suction nozzle is linearly arrayed on the buffer plate.

[0026] By adopting the above technical solution, the long tube of the infusion device is taken out by suction through the suction nozzle, thereby avoiding taking out too much material at one time.

[0027] In summary, compared with the prior art, this application has at least one of the following beneficial technical effects:

[0028] 1. During the transfer of the long infusion tubes, the pressure rod presses the stacked long infusion tubes inside the storage box to prevent the adjacent long infusion tubes inside the storage box from bending or deflecting due to friction during the transfer process. This also prevents the problem of loose adsorption due to insufficient contact area between the hose surface and the suction nozzle when the suction nozzle contacts the bent section. After the long infusion tubes are moved out of the storage box, the drive assembly drives the mounting rod and combing teeth to move to the right. The combing teeth are inserted into the stacked long infusion tubes and move to the right to straighten the bent long infusion tubes inside the storage box. This prevents the long infusion tubes from becoming messy or even getting stuck during transportation due to the material characteristics of the long tubes and the friction between adjacent long tubes.

[0029] 2. As the conveying process continues, the leveling mechanism vibrates and levels the stacked infusion tubes, preventing the unabsorbed infusion tubes from tilting and bending toward the middle adsorption area due to gravity and friction between adjacent tubes, and preventing the overall loose and messy arrangement of the infusion tubes from affecting the conveying efficiency. This facilitates combing by the combing teeth and enables the suction nozzle to adsorb the infusion tubes from the upper layer to the lower layer in sequence, thereby improving the accuracy of material retrieval. Moreover, the partition can limit the infusion tubes, reduce the amplitude of bending and deviation of the infusion tubes, and improve the combing effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is a summary of the embodiments of this application. Figure 1-Figure 7 , clearly and completely describes the technical solutions of the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the described embodiments of this application, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of this application.

[0039] Reference Figure 1 、 Figure 2 and Figure 3 This embodiment provides a conveying device for infusion pump production, comprising a stand 1, a storage box 2, a picking mechanism 3, a combing mechanism 6, and a leveling mechanism 7. The combing mechanism 6 comprises two drive assemblies 61 and a mounting rod 63 disposed between the two drive assemblies 61. The mounting rod 63 has a linear array of combing teeth 64 disposed at the bottom end thereof for straightening the long infusion pump tubes stacked within the storage box 2. The leveling mechanism 7 is used to level the long infusion pump tubes within the storage box 2 that have not been transported.

[0040] Among them, reference Figure 1 The picking mechanism 3 includes an electric guide rail module 31, a finger cylinder 32 and an adsorption component 33. The electric guide rail module 31 is fixedly arranged at the left end of the platform 1. A fixed plate is provided on the movable seat 311 of the electric guide rail module 31 (the movable seat 311 is a movable component on the electric guide rail module 31, and linear motion is achieved through a ball screw). Finger cylinders 32 are provided in a linear array on the fixed plate. The adsorption component 33 is fixedly connected to the right end of the electric guide rail module 31. The adsorption component 33 is used to adsorb the long tube of the infusion pump inside the storage box 2 and transfer it to the two clamping claws of the finger cylinder 32. The movable seat 311 of the electric guide rail module 31 slides to the left to pull and transport the long tube of the infusion pump through the finger cylinder 32.

[0041] Among them, reference Figure 1 The suction component 33 includes a support plate 331, a lifting cylinder 332 and a suction nozzle 335. The support plate 331 is fixedly arranged at the right end of the electric guide rail module 31, and the lifting cylinder 332 is fixedly arranged in the middle of the support plate 331. The lower end of the push rod of the lifting cylinder 332 is provided with a connecting plate 333. The lower part of the connecting plate 333 is slidably connected to a buffer plate 334 through a guide rod. The outer arc surface of the lower end of the guide rod is sleeved with a spring, and the springs are all located between the connecting plate 333 and the buffer plate 334. The suction nozzle 335 is arranged in a linear array on the buffer plate 334. The suction nozzle 335 is connected to a negative pressure source independent of the present application through a catheter. After the suction nozzle 335 adsorbs the long tube of the infusion pump, the lifting cylinder 332 drives the suction nozzle 335 to lift the long tube of the infusion pump upward to transport the long tube of the infusion pump to the two clamps of the finger cylinder 32.

[0042] When the long tube of the infusion set is transported, the lifting cylinder 332 is controlled to work, and the push rod of the lifting cylinder 332 drives the suction nozzle 335 to move down through the connecting plate 333, the spring and the buffer plate 334 in sequence, until the suction nozzle 335 abuts against the long tube of the infusion set inside the storage box 2. When the reverse force of the infusion set long tube on the suction nozzle 335 is greater than the elastic force of the spring, the spring is compressed, causing the buffer plate 334 to move up relative to the connecting plate 333, avoiding the squeeze damage to the long tube of the infusion set caused by hard contact. Use an external negative pressure source to evacuate the suction nozzle 335, and the suction nozzle 335 adsorbs the surface of the long tube of the infusion pump, controlling the push rod of the lifting cylinder 332 to retract, and transporting the long tube of the infusion pump to the two claws of the finger cylinder 32. Control the two claws of the finger cylinder 32 to close to firmly clamp the long tube of the infusion pump, and then control the electric guide rail module 31 to work. The mover seat 311 of the electric guide rail module 31 drives the finger cylinder 32 to move to the left through the fixed plate, thereby pulling and transporting the long tube of the infusion pump.

[0043] Reference Figure 1 and Figure 2 The two ends of the mounting rod 63 are rotatably provided with connecting rings 65, and the two connecting rings 65 are provided with connecting rods 66. A pressure rod 67 is fixedly provided between the two connecting rods 66, which is used to press one end of the long tube of the infusion set during the combing process. The outer arc surface of the pressure rod 67 is rotatably connected with a sleeve 69. The sleeve 69 reduces the friction force on the long tube of the infusion set during movement. A torsion spring 68 is provided between the inside of the connecting ring 65 and the outer arc surface of the mounting rod 63. The pressure rod 67 is in elastic contact with the surface of the long tube of the infusion set through the torsion spring 68 rather than rigid extrusion, which can avoid deformation or surface scratches of the long tube of the infusion set due to excessive pressure during the combing process, thereby improving product quality.

[0044] When the finger cylinder 32 pulls the long tube of the infusion device to move to the left, the pressure rod 67 drives the sleeve 69 under the torsion of the torsion spring 68 to press the long tubes of the infusion device stacked inside the storage box 2, so as to avoid the bending and displacement of the adjacent long tubes of the infusion device due to friction, and prevent the neatness of the stacking of the ends of the infusion device from being damaged.

[0045] Reference Figure 1 and Figure 2The driving component 61 includes an L-shaped mounting base 611, a transmission wheel 612 and a belt 613. There are four L-shaped mounting bases 611 and they are respectively arranged on the front and rear side walls of the storage box 2. The vertical parts of the L-shaped mounting base 611 are rotatably connected to the transmission wheel 612 through a rotating shaft. The two transmission wheels 612 corresponding to the left and right directions are connected by a belt 613, and the two rotating shafts on the right are connected by a connecting rod 614. The vertical part of the L-shaped mounting base 611 at the rear right end is fixed with a motor 615. The output shaft of the motor 615 is fixedly connected to the rear end of the connecting rod 614 through a coupling. The mounting rod 63 is fixedly connected to the outer surface of the two belts 613 respectively. The bottom end of the mounting rod 63 is provided with a linear array of combing teeth 64 for straightening the long infusion tubes stacked inside the storage box 2.

[0046] The control motor 615 works, and the output shaft of the motor 615 drives the two transmission wheels 612 on the right to rotate through the connecting rod 614, and then drives the mounting rod 63 and the combing teeth 64 to move to the right through the belt 613. The combing teeth 64 are inserted into the stacked infusion tubes and move to the right to straighten the bent infusion tubes inside the storage box 2. During the combing process, the sleeve 69 presses the left side of the infusion tube in real time, effectively preventing the friction between the combing teeth 64 and the infusion tube from causing the combed part of the infusion tube to shift. After the combing is completed, the mounting rod 63 and the combing teeth 64 are driven by the belt 613 to move in the opposite direction from the top to the right side of the partition 72 to assist the suction nozzle 335 in taking the material.

[0047] Reference Figure 2 and Figure 3 A limit support plate 62 is fixedly arranged between the two L-shaped mounting seats 611 corresponding to the left and right directions. A boss 621 is provided in the middle of the limit support plate 62. The outer surface of the boss 621 is in sliding contact with the inner surface of the belt 613 on the same side. The boss 621 reduces the deformation of the belt 613 by supporting it, ensuring the transmission accuracy of the belt 613, thereby making the combing teeth 64 move along the preset trajectory to avoid misalignment of the long tube of the infusion pump.

[0048] Reference Figure 3 and Figure 5 The inner wall surface of the storage box 2 is slidably connected with a lifting plate 4, and the bottom plate of the storage box 2 is fixedly provided with a linear driver 5. The execution end of the linear driver 5 is fixedly connected to the lower surface of the lifting plate 4. The linear driver 5 is an electric push rod. During the continuous transfer of the long tube of the infusion device in the storage box 2, the push rod of the linear driver 5 extends to drive the lifting plate 4 to move upward, thereby lifting the long tube of the infusion device placed on the upper surface of the lifting plate 4.

[0049] Reference Figure 3 、 Figure 4 、 Figure 6 and Figure 7The leveling mechanism 7 includes a mounting plate 71, a partition 72 and a second driving component 73. A slide rail 74 is fixedly provided on the inner bottom surface of the storage box 2. The mounting plate 71 is fixedly provided on the slider of the slide rail 74. A linear array of partitions 72 is provided on the upper surface of the mounting plate 71. The partitions 72 are used to limit the stacked long tubes of the infusion pump and reduce the bending and offset amplitude of the long tubes of the infusion pump. A through hole 41 is provided on the lifting plate 4 for avoiding the partition 72. The second driving component 73 includes a second motor 731, a turntable 732, a convex shaft 733 and a groove plate 734. A second motor 731 is fixedly provided on the lower surface of the bottom plate of the storage box 2. A turntable 732 is fixedly provided on the output shaft of the second motor 731. A convex shaft 733 is eccentrically provided on the turntable 732. A groove plate 734 is fixedly provided on the lower surface of the mounting plate 71. The convex shaft 733 is in sliding contact with the inner wall of the groove plate 734.

[0050] During use, the suction nozzle 335 continuously absorbs the vertically corresponding long tube of the infusion device and transfers it through the finger cylinder 32. As the conveying process continues, the long tube of the infusion device vertically corresponding to the suction nozzle 335 gradually decreases, while the long tube of the infusion device that has not been adsorbed on both sides still remains and accumulates at the edge of the conveying area due to the lack of effective constraints. At this time, the control motor 2 731 works, and the output shaft of the motor 2 731 drives the turntable 732 to rotate. The convex shaft 733 is eccentrically installed on the turntable 732. When the turntable 732 rotates, the convex shaft 733 rotates. Sliding in the long groove of the groove plate 734, the mounting plate 71 is periodically swung back and forth in the front-to-back direction by the limit of the slide rail 74, thereby driving the partition 72 to swing back and forth through the mounting plate 71, and vibrating and leveling the stacked long tubes of the infusion pump, so as to prevent the remaining long tubes of the infusion pump from tilting and bending toward the middle adsorption area due to gravity and friction between adjacent long tubes, and prevent the overall arrangement of the long tubes of the infusion pump from being loose and disordered, while ensuring that the suction nozzle 335 can adsorb the long tubes of the infusion pump in sequence from the upper layer to the lower layer to reduce clutter.

[0051] Reference Figure 7 A groove 735 is provided inside the turntable 732, and the convex shaft 733 is slidably connected to the inside of the groove 735. The internal thread of the turntable 732 is connected to the screw rod 736, and the screw rod 736 is rotatably connected to the T-slot provided inside the convex shaft 733. When the screw rod 736 is rotated, the screw rod 736 drives the convex shaft 733 to move radially relative to the turntable 732, adjusting the distance between the axis of the turntable 732 and the convex shaft 733, thereby controlling the swing amplitude of the groove plate 734 during rotation.

[0052] The implementation principle of a delivery device for producing an infusion set according to an embodiment of the present application is as follows:

[0053] The long tube of the infusion pump is placed in the storage box 2 and abutted against the inner left wall of the storage box 2. The lifting cylinder 332 is controlled to work. The push rod of the lifting cylinder 332 drives the suction nozzle 335 to move down to the inside of the storage box 2. The external negative pressure source draws air from the suction nozzle 335. The suction nozzle 335 adsorbs the surface of the long tube of the infusion pump. The push rod of the lifting cylinder 332 is controlled to contract and the long tube of the infusion pump is transported to the two claws of the finger cylinder 32. The two claws of the finger cylinder 32 are closed to firmly clamp the long tube of the infusion pump. Then the electric guide rail module 31 is controlled to work. The mover seat 311 of the electric guide rail module 31 drives the finger cylinder 32 to move to the left through the fixed plate to pull and transport the long tube of the infusion pump.

[0054] During the transfer of the infusion tube to the left, the pressure rod 67, under the torsion force of the torsion spring 68, presses the upper layer of the infusion tubes inside the storage box 2 through the sleeve 69, preventing the transferred infusion tube from bending or deflecting adjacent infusion tubes due to friction. After the infusion tube is removed from the storage box 2, the second motor 731 is controlled to operate. The output shaft of the second motor 731 rotates the cam 733 via the turntable 732. The cam 733 slides within the groove plate 734, driving the groove plate 734 to swing back and forth. This, in turn, drives the partition plate 72 to swing back and forth through the mounting plate 71, vibrating and leveling the stacked infusion tubes. This prevents the infusion tubes vertically corresponding to the suction nozzle 335 from being continuously removed while a large number of adjacent infusion tubes remain, resulting in an uneven upper layer of the stacked infusion tubes.

[0055] After leveling is completed, the motor 1 615 is controlled to work, and the output shaft of the motor 1 615 drives the two transmission wheels 612 on the right to rotate through the connecting rod 614, and then drives the mounting rod 63 and the combing teeth 64 to move to the right through the belt 613. The combing teeth 64 are inserted into the stacked infusion tubes and move to the right to straighten the bent infusion tubes inside the storage box 2.

[0056] In addition, in the description of this application, the terms "install", "connect", "connect", and "set" should be understood in a broad sense, and those skilled in the art can understand the specific meanings of the above terms in this application according to the circumstances.
