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 the core medical device for clinical intravenous drug administration, the infusion set integrates precision components such as puncture sets, infusion hoses, drip buckets, flow rate regulators and intravenous needles. Relying on the gravity-driven principle and precise flow rate control technology, a safe and stable liquid drug transmission channel is constructed to accurately deliver therapeutic drugs to the human circulatory system. In the modern medical device manufacturing scenario, the efficient and stable transmission of the long tube of the infusion set is a key node to maintain the continuous operation of the automated production line, which directly affects product quality and production efficiency.

[0003] In the infusion set assembly production process of the prior art, the long infusion set tubes 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, adsorbs one end of the long infusion set tube from the inside of the storage box, and lifts it to the inside of the two clamping claws of the finger cylinder. The finger cylinder clamps the end of the long infusion set tube and is pulled and transported to the left by the electric guide rail module to transport the long infusion set tube to the carrier of the assembly machine.

[0004] Regarding the above-mentioned related technologies, when the finger cylinder pulls the long tube of the infusion pump along the electric guide module, due to the flexibility of the long tube material and the friction between adjacent long tubes, it is very easy to cause the bending and deviation of the surrounding long tubes, destroying the original regular stacking state. When the suction nozzle contacts the deformed long tube, the effective fitting area between the long tube surface and the adsorption surface is reduced, and vacuum adsorption failure often occurs. This type of unstable adsorption problem will directly lead to long tube leakage, mid-way detachment and other faults, significantly reducing the production line transportation efficiency, and becoming a technical bottleneck restricting the efficiency and production capacity of automated assembly. 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 process of the long tube of the infusion pump.

[0006] In order 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 a long tube of the infusion set, and a picking mechanism for transferring the long tube of the infusion set; A lifting plate is slidably connected to the inner wall surface of the accommodation box. A linear driver is fixedly arranged on the bottom plate of the accommodation box, and the execution end of the linear driver is fixedly connected to the lower surface of the lifting plate. Driving components I are arranged on the front and rear side walls of the accommodation box. An installation rod is arranged between the two driving components I. Comb teeth are linearly arranged at the bottom end of the installation rod for straightening the long infusion tubes stacked inside the accommodation box. Connecting rings are rotatably arranged at both ends of the installation rod. Connecting rods are arranged on both connecting rings, and a pressing rod is fixedly arranged between the two connecting rods for pressing one end of the infusion tube during the combing process of the long infusion tube.

[0007] By adopting the above technical solution, during the transfer process of the long infusion tubes, the pressing rod presses the long infusion tubes stacked inside the accommodation box, avoiding the bending and offset of adjacent long infusion tubes inside the accommodation box due to friction during the transfer process of the long infusion tubes, and preventing the problem of insecure adsorption when the suction nozzle contacts the bent section due to insufficient fitting area between the surface of the hose and the suction nozzle. In addition, after the long infusion tubes are removed from the accommodation box, the driving component I drives the installation rod and the comb teeth to move to the right, and the comb teeth are inserted into the stacked long infusion tubes and move to the right to straighten the bent long infusion tubes inside the accommodation box, avoiding the phenomenon of messy or jammed long infusion tubes during the conveying process due to the material characteristics of the long tubes and the friction between adjacent long tubes.

[0008] Optionally, torsion springs are arranged between the inside of the connecting ring and the outer arc surface of the installation rod.

[0009] By adopting the above technical solution, the torsion spring makes the pressing rod elastically contact with the surface of the long infusion tube, which can avoid the deformation or surface scratches of the long infusion tube caused by excessive pressure during the combing process and improve the product quality.

[0010] Optionally, a sleeve is rotatably connected to the outer arc surface of the pressing rod.

[0011] By adopting the above technical solution, the sleeve rolls on the surface of the long infusion tube during the movement, reducing the friction force on the long infusion tube and reducing the probability of the long infusion tube bending.

[0012] Optionally, an installation plate is arranged on the left side inside the accommodation box. Partition plates are linearly arranged on the upper surface of the installation plate, and through holes for avoiding the partition plates are arranged on the lifting plate.

[0013] By adopting the above technical solution, the long infusion tubes are limited by the partition plates, reducing the amplitude of bending and offset of the long infusion tubes and facilitating the combing of them.

[0014] Optionally, a slide rail is fixedly arranged on the inner bottom surface of the accommodation box, the mounting plate is fixedly arranged on the slider of the slide rail, a second motor is fixedly arranged on the lower surface of the bottom plate of the accommodation box, a turntable is fixedly arranged on the output shaft of the second motor, a convex shaft is eccentrically arranged on the turntable, a channel-shaped plate is fixedly arranged on the lower surface of the mounting plate, and the convex shaft is in sliding contact with the inner wall of the channel-shaped plate.

[0015] By adopting the above technical solution, the partition board is driven to swing reciprocally to vibrate and level the stacked long infusion tubes, ensuring that the suction nozzle can adsorb the long infusion tubes from the upper layer to the lower layer in sequence, and reducing messiness.

[0016] Optionally, a groove is arranged inside the turntable, the convex shaft is slidably connected inside the groove, a screw rod is threadedly connected inside the turntable, and the screw rod is rotationally connected with a T-shaped groove arranged inside the convex shaft.

[0017] By adopting the above technical solution, when the screw rod is rotated, the screw rod drives the convex shaft to move radially relative to the turntable, adjusting the distance between the axis of the turntable and the convex shaft, thereby controlling the swing amplitude of the channel-shaped plate during rotation.

[0018] Optionally, the first driving assembly includes an L-shaped mounting seat, a transmission wheel and a belt. There are four L-shaped mounting seats which are respectively arranged on the front and rear side walls of the accommodation box. Transmission wheels are rotatably connected to the vertical parts of the L-shaped mounting seats through rotating shafts. The two transmission wheels corresponding in the left-right direction are connected by a belt in transmission. A connecting rod is connected in transmission between the two rotating shafts on the right side. A first motor is fixedly arranged on the vertical part of the L-shaped mounting seat at the right rear end. The output shaft of the first motor 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.

[0019] By adopting the above technical solution, the mounting rod and the comb teeth are driven to move to the right by the belt, and the comb teeth are inserted into the stacked long infusion tubes and move to the right to straighten the bent long infusion tubes inside the accommodation box.

[0020] Optionally, it further includes a limiting support plate. There are two limiting support plates which are respectively fixedly connected between the two L-shaped mounting seats corresponding in the left-right direction. Convex platforms are arranged in the middle of the limiting support plates, and the outer surfaces of the convex platforms are respectively in sliding contact with the inner surfaces of the belts on the same side.

[0021] By adopting the above technical solution, the convex platforms are used to support the belts, avoiding excessive deformation during rotation and affecting the combing effect on the long infusion tubes.

[0022] Optionally, the picking mechanism includes an electric guide rail module, a finger cylinder, and an adsorption component. The electric guide rail module is fixedly arranged at the left end of the bench. The finger cylinders are arranged in a linear array on the moving seat of the electric guide rail module. The electric guide rail module is used to drive the finger cylinders to move left and right to traction and convey the long tube of the infusion set. The adsorption component is fixedly connected to the right end of the electric guide rail module, and the adsorption component is used to adsorb the long tube of the infusion set inside the accommodation box and transfer it into the two jaws of the finger cylinder.

[0023] By adopting the above technical solution, the two jaws of the finger cylinder are closed to firmly clamp the long tube of the infusion set, and then it is transferred through the electric guide rail module, avoiding the long tube of the infusion set falling off during the transfer process.

[0024] Optionally, the adsorption component 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 in the middle of the support plate. A connecting plate is arranged at the lower end of the push rod of the lifting cylinder. A buffer plate is slidably connected below the connecting plate through a guide rod. The suction nozzles are arranged in a linear array on the buffer plate.

[0025] By adopting the above technical solution, the long tube of the infusion set is taken out by adsorption of the suction nozzle, avoiding taking out too much material at one time.

[0026] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects: 1. During the transfer of the long tube of the infusion set, the pressing rod presses the stacked long tubes of the infusion set inside the accommodation box, avoiding the adjacent long tubes of the infusion set inside the accommodation box being bent and offset due to friction during the transfer of the long tube of the infusion set, preventing the problem of insufficient adsorption firmness due to the insufficient fitting area between the hose surface and the suction nozzle when the suction nozzle contacts the bent section. After the long tube of the infusion set is removed from the accommodation box, the first driving component drives the mounting rod and the comb teeth to move to the right, and the comb teeth are inserted into the stacked long tubes of the infusion set and move to the right to straighten the bent long tubes of the infusion set inside the accommodation box, avoiding the phenomenon of the long tubes of the infusion set being messy or even jammed during the conveying process due to the material characteristics of the long tubes and the friction between adjacent long tubes.

[0027] 2. As the conveying process continues, the leveling mechanism works to vibrate and level the stacked long tubes of the infusion set, avoiding the unadsorbed long tubes of the infusion set tilting and bending towards the middle adsorption area due to gravity and the friction between adjacent long tubes, preventing the overall arrangement of the long tubes of the infusion set from being loose and messy and affecting the conveying efficiency, facilitating the combing of the comb teeth, and enabling the suction nozzle to adsorb the long tubes of the infusion set sequentially from the upper layer to the lower layer, improving the accuracy of material taking; moreover, the partition plate can limit the long tubes of the infusion set, reducing the amplitude of bending and offset of the long tubes of the infusion set and improving the combing effect.

Detailed implementation manners

[0030] Next, in combination with the Figures 1-7 embodiments of this application, the technical solutions of the embodiments of this application will be clearly and completely described. Obviously, the described embodiments are part of the embodiments of this application, rather than all of the embodiments. Based on the described embodiments of this application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by this application.

[0031] Referring to Figure 1 , Figure 2 and Figure 3, this embodiment provides a conveying device for the production of infusion sets, including a bench 1, a storage box 2, a picking mechanism 3, a combing mechanism 6 and a leveling mechanism 7. Among them, the combing mechanism 6 includes two first driving components 61 and a mounting rod 63 arranged between the two first driving components 61. Comb teeth 64 are linearly arranged at the bottom end of the mounting rod 63, which are used to straighten the long infusion set tubes stacked inside the storage box 2; the leveling mechanism 7 is used to level the long infusion set tubes that have not been conveyed inside the storage box 2.

[0032] Among them, referring to 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 bench 1. A fixing plate is arranged on the moving seat 311 of the electric guide rail module 31 (the moving seat 311 is a movable part on the electric guide rail module 31, and linear motion is realized through a ball screw). Finger cylinders 32 are linearly arranged on the fixing 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 infusion set tubes inside the storage box 2 and transfer them into the two jaws of the finger cylinder 32. The moving seat 311 of the electric guide rail module 31 slides to the left to traction-convey the long infusion set tubes through the finger cylinder 32.

[0033] Among them, referring to Figure 1 , the adsorption 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. The lifting cylinder 332 is fixedly arranged in the middle of the support plate 331. A connecting plate 333 is arranged at the lower end of the push rod of the lifting cylinder 332. A buffer plate 334 is slidably connected below the connecting plate 333 through a guide rod. Springs are sleeved on the outer arc surfaces of the lower ends of the guide rods, and the springs are all located between the connecting plate 333 and the buffer plate 334. The suction nozzles 335 are linearly arranged on the buffer plate 334. The suction nozzles 335 are communicated with a negative pressure source independent of this application through a conduit. After the suction nozzles 335 adsorb the long infusion set tubes, the lifting cylinder 332 drives the suction nozzles 335 to lift upward to convey the long infusion set tubes into the two jaws of the finger cylinder 32.

[0034] When transporting the long tube of the infusion set, the lifting cylinder 332 is controlled to work. The push rod of the lifting cylinder 332 drives the suction nozzle 335 to move downward 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 accommodation box 2. When the reverse force of the long tube of the infusion set 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 upward relative to the connecting plate 333, avoiding extrusion damage to the long tube of the infusion set caused by hard contact. At this time, an external negative pressure source is enabled to extract air from the suction nozzle 335, and the suction nozzle 335 adsorbs the surface of the long tube of the infusion set. Then, the push rod of the lifting cylinder 332 is controlled to contract, transporting the long tube of the infusion set into the two clamping jaws of the finger cylinder 32. The two clamping jaws of the finger cylinder 32 are controlled to close to firmly clamp the long tube of the infusion set. Then, the electric guide rail module 31 is controlled to work, and the moving seat 311 of the electric guide rail module 31 drives the finger cylinder 32 to move to the left through the fixing plate, pulling and transporting the long tube of the infusion set.

[0035] Refer to Figure 1 and Figure 2 At both ends of the mounting rod 63, connecting rings 65 are rotatably arranged. On both connecting rings 65, connecting rods 66 are arranged. A pressing rod 67 is fixedly arranged 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 pressing 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 arranged between the inside of the connecting ring 65 and the outer arc surface of the mounting rod 63. The pressing rod 67 is elastically in contact with the surface of the long tube of the infusion set through the torsion spring 68 instead of rigid extrusion, which can avoid deformation or surface scratches of the long tube of the infusion set caused by excessive pressure during the combing process and improve product quality.

[0036] During the process of the finger cylinder 32 pulling the long tube of the infusion set and moving it to the left, the pressing rod 67 drives the sleeve 69 under the torque of the torsion spring 68 to press the stacked long tubes of the infusion set inside the accommodation box 2, avoiding bending and offset of adjacent long tubes of the infusion set due to friction force and preventing damage to the stacking neatness of the ends of the long tubes of the infusion set.

[0037] Refer to Figure 1 and Figure 2The driving component 61 includes an L-shaped mounting seat 611, a transmission wheel 612 and a belt 613. There are four L-shaped mounting seats 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 seats 611 are rotatably connected with the transmission wheels 612 through a rotating shaft. The two corresponding transmission wheels 612 in the left and right directions are transmission-connected by a belt 613, and the two rotating shafts on the right are transmission-connected by a connecting rod 614. A motor 615 is fixedly arranged on the vertical part of the L-shaped mounting seat 611 at the right end of the rear side, and the output shaft of the motor 615 is fixedly connected to the rear end of the connecting rod 614 through a coupling. The mounting rods 63 are respectively fixedly connected to the outer surfaces of the two belts 613, and the bottom end of the mounting rods 63 is linearly arrayed with combing teeth 64 for straightening the long tubes of the infusion sets stacked inside the storage box 2.

[0038] The control motor 615 works, and the output shaft of the motor 615 drives the two transmission wheels 612 on the right side 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 long tubes of the infusion pump and move to the right to straighten the bent long tubes of the infusion pump inside the storage box 2. During the combing process, the sleeve 69 presses the left side of the long tube of the infusion pump in real time, effectively preventing the friction between the combing teeth 64 and the long tube of the infusion pump from causing the combed part of the long tube of the infusion pump 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 materials.

[0039] 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, and a boss 621 is arranged in the middle of the limit support plate 62. The outer surfaces of the boss 621 are in sliding contact with the inner surfaces of the belt 613 on the same side respectively. The boss 621 reduces the deformation of the belt 613 by supporting it, thereby ensuring the transmission accuracy of the belt 613, and then the combing teeth 64 move along the preset trajectory to avoid the combing dislocation of the long tube of the infusion set.

[0040] 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 set in the storage box 2, the push rod of the linear driver 5 is extended to drive the lifting plate 4 to move upward, thereby lifting the long tube of the infusion set placed on the upper surface of the lifting plate 4.

[0041] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7, the leveling mechanism 7 includes a mounting plate 71, a partition plate 72 and a second driving assembly 73. A slide rail 74 is fixedly arranged on the inner bottom surface of the accommodating box 2. The mounting plate 71 is fixedly arranged on the slider of the slide rail 74. The partition plates 72 are linearly arranged in an array on the upper surface of the mounting plate 71. The partition plates 72 are used to limit the long tubes of the infusion sets in a stacked manner, reducing the amplitude of bending and offset of the long tubes of the infusion sets. A through hole 41 for avoiding the partition plate 72 is arranged on the lifting plate 4. The second driving assembly 73 includes a second motor 731, a turntable 732, a convex shaft 733 and a grooved plate 734. The second motor 731 is fixedly arranged on the lower surface of the bottom plate of the accommodating box 2. A turntable 732 is fixedly arranged on the output shaft of the second motor 731. A convex shaft 733 is eccentrically arranged on the turntable 732. A grooved plate 734 is fixedly arranged on the lower surface of the mounting plate 71. The convex shaft 733 is in sliding contact with the inner wall of the grooved plate 734.

[0042] During the use process, the suction nozzle 335 continuously sucks the long tubes of the infusion sets corresponding vertically and transfers them through the finger cylinder 32. As the conveying process continues, the long tubes of the infusion sets corresponding vertically to the suction nozzle 335 gradually decrease. However, the long tubes of the infusion sets not adsorbed on both sides lack effective restraint and still remain in large quantities and accumulate at the edge of the conveying area. At this time, control the second motor 731 to work. The output shaft of the second motor 731 drives the turntable 732 to rotate. The convex shaft 733 is eccentrically installed on the turntable 732 and slides in the long groove of the grooved plate 734 when rotating with the turntable 732. By using the limit of the slide rail 74, the mounting plate 71 makes a periodic reciprocating swing in the front-rear direction, so as to drive the partition plate 72 to reciprocate through the mounting plate 71, vibrating and leveling the stacked long tubes of the infusion sets, avoiding the remaining long tubes of the infusion sets from tilting and bending towards the middle adsorption area due to the action of gravity and the friction between adjacent long tubes, preventing the overall arrangement of the long tubes of the infusion sets from being loose and disorderly, and at the same time ensuring that the suction nozzle 335 can adsorb the long tubes of the infusion sets from the upper layer to the lower layer in sequence, reducing messiness.

[0043] Refer to Figure 7 , a groove 735 is arranged inside the turntable 732. The convex shaft 733 is slidably connected inside the groove 735. A screw 736 is threadedly connected inside the turntable 732. The screw 736 is rotationally connected with a T-shaped groove arranged inside the convex shaft 733. Rotate the screw 736, and the screw 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, so as to control the swing amplitude of the grooved plate 734 during rotation.

[0044] The implementation principle of a conveying device for the production of infusion sets in an embodiment of the present application is as follows: Place the long tube of the infusion set inside the accommodating box 2 and make it abut against the inner left wall surface of the accommodating box 2. Control the lifting air cylinder 332 to work. The push rod of the lifting air cylinder 332 drives the suction nozzle 335 to move downward into the interior of the accommodating box 2. The external negative pressure source sucks air from the suction nozzle 335, and the suction nozzle 335 adsorbs the surface of the long tube of the infusion set. Control the push rod of the lifting air cylinder 332 to contract, and convey the long tube of the infusion set into the two clamping jaws of the finger air cylinder 32. The two clamping jaws of the finger air cylinder 32 close to firmly clamp the long tube of the infusion set. Then control the electric guide rail module 31 to work. The moving seat 311 of the electric guide rail module 31 drives the finger air cylinder 32 to move to the left through the fixed plate, and tractionally conveys the long tube of the infusion set.

[0045] During the process of the long tube of the infusion set being moved to the left, the pressure rod 67 presses the upper layer of the long tube of the infusion set inside the accommodating box 2 through the sleeve 69 under the torsion of the torsion spring 68, so as to prevent the adjacent long tubes of the infusion set from bending and shifting due to friction during the transfer. After the long tube of the infusion set is moved out of the accommodating box 2, control the second motor 731 to work. The output shaft of the second motor 731 drives the camshaft 733 to rotate through the turntable 732. The camshaft 733 slides inside the grooved plate 734 to drive the grooved plate 734 to swing back and forth in the front-back direction, thereby driving the partition plate 72 to swing back and forth through the mounting plate 71, and vibrating and leveling the stacked long tubes of the infusion set, so as to prevent the long tubes of the infusion set corresponding vertically to the suction nozzle 335 from being continuously taken out, while there are still many long tubes of the infusion set remaining in the adjacent positions, resulting in unevenness on the upper layer of the stacked long tubes of the infusion set.

[0046] After leveling is completed, control the first motor 615 to work. The output shaft of the first motor 615 drives the two transmission wheels 612 on the right side to rotate through the connecting rod 614, and then drives the mounting rod 63 and the comb teeth 64 to move to the right through the belt 613. The comb teeth 64 are inserted into the stacked long tubes of the infusion set and move to the right to straighten the bent long tubes of the infusion set inside the accommodating box 2.

[0047] In addition, in the description of the present application, the terms "installation", "connection", "connection", and "setting" should be understood in a broad sense, and those skilled in the art can understand the specific meanings of the above terms in the present application according to the circumstances.
