[0029] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings.

[0030] Please refer to Figure 1 which is a structural schematic diagram of the material circulation system 1 shown in the present application. Please refer to Figure 2which is a partial explosion schematic view of the material circulation system 1 shown in the present application. As shown in Figure 1 and Figure 2 The material circulation system 1 in the present application comprises a placing rack 10, a hopper module 20, a carrier 101, a feeding module, a driving module and a taking module 90; wherein the placing rack 10 is provided with a material placing station 11 and a material taking station 12; the hopper module 20 is arranged on the placing rack 10 and is used for placing materials; each carrier 101 is provided with a material cavity for placing materials; the feeding module is used for taking out the materials in the hopper module 20 and placing them in the material cavity of the carrier 101 located at the material placing station 11; the driving module is used for moving the carrier 101 at the material placing station 11 to the material taking station 12 according to a first path; the taking module 90 is used for taking out the materials in the carrier 101 located at the material taking station 12 and transmitting them to a subsequent station, and the subsequent station is used for processing and manufacturing medical catheter assemblies from the materials; the driving module is used for transmitting the carrier 101 located at the material taking station 12 to the material placing station 11 according to a second path after the materials are taken out by the taking module 90.

[0031] It can be seen that a certain number of carriers 101 are always moved between the material placing station 11 and the material taking station 12 on the placing rack 10 under the driving of the driving module. However, because there are multiple carriers 101 on the placing rack 10, when the carrier 101 without materials placed therein at the material placing station 11 is moved to the material taking station 12, it needs a certain time to be moved back to the material placing station 11 again, and when it is moved back to the material placing station 11 again, it can carry materials; this makes the carrier 101 not transport materials and experience a long waiting time, greatly affecting the material taking efficiency of the taking module 90 and further affecting the manufacturing efficiency of the medical catheter assemblies. To solve the above problem, in the present application, a detection module is arranged, when the feeding module takes out the materials in the hopper module 20 and places them in the material cavity of the carrier 101 located at the material placing station 11, the detection module detects whether the material cavity of each carrier 101 has materials placed therein, and the driving module keeps the carrier 101 without materials placed therein at the material placing station 11 according to the detection result of the detection module, and moves the carrier 101 with materials placed therein from the material placing station 11 to the material taking station 12. Through the above manner, the carrier 101 with materials placed therein is moved to the material taking station 12, which relieves the situation that the empty carrier 101 is moved empty, and improves the material taking efficiency of the taking module 90 and the manufacturing efficiency of the medical catheter assemblies.

[0032] Of course, it can be understood that the detection module can be located on one side of the material placing station 11, or the detection module can be located above the material placing station 11.

[0033] As shown in Figure 2As shown, a plurality of liftable limiting units 61 are arranged around the material placing station 11 on the rack 10, the limiting units 61 are in one-to-one alignment with the carriers 101 at the material placing station 11, the limiting units 61 are used to be lifted when there is no material placed in the material cavity of the aligned carrier 101, at this time, even if the driving module is actuated, the driving module cannot move the carrier 101 with no material placed in the material cavity to the material taking station 12 under the block of the limiting units 61, thereby realizing that the carrier 101 with no material placed in the material cavity is left in the material placing station 11; the limiting units 61 are used to be lowered when there is material placed in the material cavity of the aligned carrier 101, so that the driving module can move the carrier 101 with material placed in the material cavity to the material taking station 12 when actuated.

[0034] By arranging the limiting units 61, the carrier 101 with no material placed in the material cavity cannot be moved to the material taking station 12 when the driving module is actuated, which fully alleviates the occurrence of empty carrier 101 transmission, and guarantees the material taking efficiency of the material taking module 90 and the manufacturing efficiency of the medical catheter assembly.

[0035] As shown, Figure 1 The driving module includes a first driving module 41 and a second driving module 42, and first and second transmission links arranged at intervals; the transmission directions of the first and second transmission links are opposite; the conveying starting end of the first transmission link is the material taking station 12, and the conveying ending end of the first transmission link is the material placing station 11; the conveying starting end of the second transmission link is the first transfer station 13, and the conveying ending end of the second transmission link is the second transfer station 14; the first driving module 41 is used to move the carrier 101 with material placed in the material cavity from the material placing station 11 to the first transfer station 13 according to the detection result of the detection module, the second transmission link is used to move the carrier 101 at the first transfer station 13 to the second transfer station 14, the second driving module 42 is used to move the carrier 101 at the second transfer station 14 to the material taking station 12, and the second transmission link is used to transmit the carrier 101 at the material taking station 12 to the material placing station 11 after the material taking module 90 takes out the material.

[0036] The first driving module 41 can be a cylinder mechanism with a plurality of piston rods, the number of piston rods is equal to the maximum number of carriers 101 that can be placed in the material placing station 11, as shown in Figure 1As shown, in the embodiment, the piston rods are six; each piston rod is aligned with a carrier 101 on the feeding station 11, when the material cavity of the carrier 101 aligned with the piston rod is placed with material, the piston rod will transfer the carrier 101 aligned to the first transfer station 13. Because the second transmission link is a belt mechanism, the first transfer station 13 is located at the conveying starting end of the second transmission link, and the second transfer station 14 is located at the conveying end of the second transmission link, the second transmission link can transmit the carrier 101 located at the first transfer station 13 to the second transfer station 14 by the belt transmission, and stop after successful transmission; the second transfer station 14 is aligned with the second drive module 42, the second drive module 42 can be a cylinder mechanism, having a plurality of piston rods, each piston rod will transfer the carrier 101 aligned to the conveying starting end of the first transmission link; the conveying starting end of the first transmission link is the material taking station 12, the conveying end of the first transmission link is the feeding station 11, and the first transmission link is a belt mechanism, so at this time the second drive module 42 transmits the carrier 101 to the conveying starting end of the first transmission link, that is, the material taking station 12, the material taking module 90 can take out the material in the carrier 101 located at the material taking station 12; after taking out, the carrier 101 located at the material taking station 12 can be transmitted to the feeding station 11 by belt transmission.

[0037] In the above embodiment, the carrier 101 is moved between the material taking station 12 and the feeding station 11 by the combination of belt transmission and cylinder drive, the transmission mode is simple and easy to realize, and the mechanism is compact.

[0038] Among them, the arrangement positions of the feeding station 11, the material taking station 12, the first transfer station 13 and the second transfer station 14 on the placement rack 10 can be changed; for example, the position of the feeding station 11 is set to the position of the first transfer station 13 in the first transfer station 13, Figure 1 the position of the first transfer station 13 is set to the position of the feeding station 11 in the feeding station 11, Figure 1 the position of the second transfer station 14 is set to the position of the material taking station 12 in the material taking station 12, Figure 1 the position of the material taking station 12 is set to the position of the second transfer station 14 in the second transfer station 14, Figure 1 and the position of the second transfer station 14 is set to the position of the material taking station 12 in the material taking station 12.

[0039] Because the carrier 101 will cross two belt mechanisms when it is transmitted from the feeding station 11 to the first transfer station 13 and from the second transfer station 14 to the material taking station 12, the carrier 101 may rub the belt during transmission, and the belt will be worn after long-time and multiple rubbing; for example, Figure 2As shown, in the present application, the first lifting unit 51 is arranged on the feeding station 11, the second lifting unit 52 is arranged on the first transfer station 13, the third lifting unit 53 is arranged on the second transfer station 14, and the fourth lifting unit 54 is arranged on the taking station 12. When the carrier 101 is transferred from the feeding station 11 to the first transfer station 13, the first lifting unit 51 and the second lifting unit 52 can be lifted to transfer the carrier 101 from the feeding station 11 to the first transfer station 13 without contacting the belt, and then the first lifting unit 51 and the second lifting unit 52 are lowered after successful transfer. When the carrier 101 is transferred from the second transfer station 14 to the taking station 12, the third lifting unit 53 and the fourth lifting unit 54 can be lifted to transfer the carrier 101 from the second transfer station 14 to the taking station 12 without contacting the belt, and then the third lifting unit 53 and the fourth lifting unit 54 are lowered after successful transfer. By transferring the carrier 101 from the feeding station 11 to the first transfer station 13 without contacting the belt and transferring the carrier 101 from the second transfer station 14 to the taking station 12 without contacting the belt, the friction on the belt is reduced, the service life of the belt is prolonged, the production cost is saved, and certain economic benefits are achieved. The feeding station 11, the first transfer station 13, the second transfer station 14, and the taking station 12 can be provided with mounting grooves, and the first lifting unit 51, the second lifting unit 52, the third lifting unit 53, and the fourth lifting unit 54 can be arranged in the mounting grooves.

[0040] As shown in Figure 3 The bunker module 20 includes a storage bunker 210 with a taking port at the bottom, and the top of the storage bunker 210 is an open mechanism through which workers can place materials in the storage bunker 210. The storage bunker 210 has a target side plate 212 and a bottom plate 211, and the bottom of the target side plate 212 is a certain distance from the bottom plate 211 to form the taking port.

[0041] The feeding module can take out the materials in the storage bunker 210 through the taking port and place them in the material cavity of the carrier 101 located at the feeding station 11. After the feeding module takes materials from the taking port, the materials at the upper part of the storage bunker 210 can fall to the bottom under the action of gravity and align with the taking port, facilitating the feeding module to take materials next time. In the prior art, the feeding module takes materials from the open mechanism at the top of the storage bunker 210, and this feeding method is prone to material taking gaps. The method in the present embodiment solves the above problem.

[0042] As shown in Figure 1As shown, the hopper module 20 further comprises a third driving module 220 arranged on the placing rack 10, and the placing rack 10 is further provided with a guide rail 110, and the third driving module 220 is used to drive the storage hopper 210 to move along the guide rail 110. After the feeding module takes out the material from the material taking port, part of the material on the upper part of the storage hopper 210 may not fall to the bottom and align with the material taking port under the action of gravity, which causes the feeding module to easily appear material taking vacancy when taking out the material next time. In the embodiment, after the feeding module takes out the material, the third driving module 220 drives the storage hopper 210 to move along the guide rail 110, and the material in the storage hopper 210 is arranged, so that the material on the upper part of the storage hopper 210 can fall back to the bottom of the storage hopper 210 and align with the material taking port under the double actions of the movement of the storage hopper 210 and the gravity of the material itself, so that the feeding module does not easily appear material taking vacancy when taking out the material next time. Further, by moving the storage hopper 210 along the guide rail 110, the feeding module takes out the material at different positions before and after, which effectively alleviates the phenomenon of not being able to take out the material caused by continuously taking out the material at the same position.

[0043] As shown in Figure 1 and Figure 2 As shown, the feeding module is provided with a separation module 30 on the material taking path. After the feeding module takes out the material in the storage hopper 210, the separation module 30 is passed, and the separation module 30 separates the plurality of materials taken by the feeding module, so that each material can be placed in a material cavity of a carrier 101 located at a placing station.

[0044] The feeding module comprises a clamping and taking driving mechanism, a moving driving mechanism and a plurality of clamping and taking pieces, and the moving driving mechanism comprises a lifting driving mechanism and a transverse driving mechanism; each clamping and taking piece can be a clamping jaw; the clamping and taking driving mechanism is connected with the plurality of clamping and taking pieces and is used to drive the plurality of clamping and taking pieces to open and close, the lifting driving mechanism is used to drive the clamping and taking pieces to move up and down, and the transverse driving mechanism is used to drive the clamping and taking pieces to move between the material placing station 11 and the storage hopper 210; when taking out the material, the clamping and taking driving mechanism first opens the plurality of clamping and taking pieces, and the lifting driving mechanism and the transverse driving mechanism cooperate to move the plurality of clamping and taking pieces to a position aligned with the material of the material taking port, and each clamping and taking piece is provided with a material after being aligned with the material of the material taking port, and then the clamping and taking driving mechanism controls the clamping and taking pieces to close and clamp the material. After the material is clamped, the lifting driving mechanism and the transverse driving mechanism cooperate to drive the clamping and taking pieces to gradually move away from the storage hopper 210, and then the material is gradually taken out from the material taking port; after the material is taken out, the transverse driving mechanism drives the clamping and taking pieces to move towards the material placing station 11. Figure 2As shown, the separation module 30 is provided with comb tooth units 31, and the gap between two adjacent comb tooth units 31 is aligned with the material cavity of the carrier 101 at the material feeding station 11. The plurality of gripping members will pass through the separation module 30 during the movement towards the material feeding station 11. The gap of the separation module 30 separates the materials to align with the material cavity of the carrier 101 at the material feeding station 11. When the plurality of gripping members move to the material feeding station 11, each gripping member is also aligned with the material cavity of the carrier 101 at the material feeding station 11. At this time, the lifting driving mechanism drives the gripping members to descend, and the gripping driving mechanism drives each gripping member to release, so as to accurately place the materials in the material cavity of the carrier 101 at the material feeding station 11. After the material feeding is completed, the transverse driving mechanism drives the gripping members to move away from the material feeding station 11. During the movement of the gripping members away from the material feeding station 11, the gripping members gradually approach the storage bin 210. When the gripping members move to the vicinity of the storage bin 210, the above process is repeated to continue to take the materials from the storage bin 210.

[0045] The detection module on the above embodiment can be arranged on the separation module 30, that is, each gap of the separation module 30 is provided with a detection module, so as to determine whether the material cavity corresponding to the gap is provided with materials by detecting whether the gap of the separation module 30 has materials passing through.

[0046] It can be understood that, as Figure 4As shown, the feeding module can include a first feeding module and a second feeding module. The first feeding module includes a first clamping driving mechanism 83, a first transverse driving mechanism 81, a first lifting driving mechanism 82, and a plurality of first clamping pieces 84. The second feeding module includes a second clamping driving mechanism 73, a second transverse driving mechanism 71, a second lifting driving mechanism 72, and a plurality of second clamping pieces 74. Each first clamping piece 84 can be a clamping jaw. The first clamping driving mechanism 83 is connected with the plurality of first clamping pieces 84 and is used to drive the plurality of first clamping pieces 84 to open and close. The first lifting driving mechanism 82 is used to drive the first clamping pieces 84 to move up and down. The first transverse driving mechanism 81 is used to drive the first clamping pieces 84 to move towards or away from the storage bin 210. Each second clamping piece 74 is a clamping jaw. The second clamping driving mechanism 73 is connected with the plurality of second clamping pieces 74 and is used to drive the plurality of second clamping pieces 74 to open and close. The second lifting driving mechanism 72 is used to drive the second clamping pieces 74 to move up and down. The second transverse driving mechanism 71 is used to drive the second clamping pieces 74 to move between the storage bin 210 and the feeding station 11. When taking the material, the first clamping driving mechanism 83 first causes the plurality of first clamping pieces 84 to open. The first lifting driving mechanism 82 and the first transverse driving mechanism 81 cooperate to move the plurality of first clamping pieces 84 to a position aligned with the material in the material taking port. After alignment with the material in the material taking port, one material is placed in each first clamping piece 84. Then the first clamping driving mechanism 83 controls the first clamping pieces 84 to close to clamp the material. After the material is clamped, the first lifting driving mechanism 82 and the first transverse driving mechanism 81 cooperate to drive the plurality of first clamping pieces 84 to gradually move away from the storage bin 210, thereby gradually taking the material out of the material taking port. After the material is completely taken out, the second clamping pieces 74 are connected with the material clamped by the first clamping pieces 84. After successful connection, the second clamping driving mechanism 73 causes the second clamping pieces 74 to close to clamp the material. Then, after the material is clamped, the first clamping driving mechanism 83 causes the first clamping pieces 84 to open. The second transverse driving mechanism 71 drives the plurality of second clamping pieces 74 to move towards the feeding station 11. The plurality of second clamping pieces 74 will pass through the separation module 30 during movement towards the feeding station 11. The gap on the separation module 30 separates the material to align the material with the material cavities of the carriers 101 located in the feeding station 11. When the plurality of second clamping pieces 74 move to the feeding station 11, each second clamping piece 74 is aligned with a material cavity of a carrier 101 located in the feeding station 11. At this time, the second lifting driving mechanism 72 drives the second clamping pieces 74 to descend, and the second clamping driving mechanism 73 drives the second clamping pieces 74 to open, thereby accurately placing the material in the material cavity of the carrier 101 located in the feeding station 11.

[0047] In the above embodiment, the first feeding module is responsible for clamping the material from the material taking port, and the second feeding module is responsible for placing the material clamped by the first feeding module in the material cavity of the carrier 101, so that each feeding module performs its own function, thereby improving the material taking efficiency.

[0048] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made by those skilled in the art based on the present application.
