Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a medical device production line. BACKGROUND

[0002] Dialyzers are vital medical devices for many kidney disease patients. In order to meet the use demand of dialyzers, dialyzers need to be produced automatically to improve production efficiency. How to realize the automatic production of dialyzers is a problem to be solved. SUMMARY

[0003] Therefore, it is necessary to provide a medical device production line. The medical device production line can realize the automatic production of dialyzers.

[0004] The present application provides a medical device production line, comprising a feeding device, an assembling device, a detecting device, a rejecting device and a transferring device. The feeding device is used to provide a first component, a second component and a third component. The third component is sleeved inside the first component. The assembling device is used to separate the third component from the first component and sleeve the third component inside the second component. The detecting device is used to detect whether the third component sleeved inside the second component is qualified. The rejecting device is used to reject the second component and the third component detected by the detecting device as unqualified. Under the transferring of the transferring device, the third component sequentially passes through the feeding device, the assembling device, the detecting device and the rejecting device.

[0005] By adopting the above technical solution, for the dialyzer, the third component is a hollow fiber and the number of the third component is multiple. The first component is a film wrapping multiple third components. The second component is a shell containing multiple third components. Multiple third components are constrained by the first component, and the end faces of multiple third components are also in an aligned state. The medical device production line can realize the automatic production of dialyzers.

[0006] In one of the embodiments, the assembling device comprises a material separating assembly and a material positioning assembly. When the first component and the third component are located inside the second component, the first component is sleeved inside the second component, and the third component is sleeved inside the first component. The material separating assembly acts on the first component to drive the first component to move relative to the second component to the first component leaving the inside of the second component. The material positioning assembly acts on the third component to limit the third component from moving with the first component.

[0007] By adopting the technical scheme, when the first component moves to be away from the inside of the second component under the action of the material distributing assembly, the third component is limited by the material positioning assembly and cannot move along with the first component. Therefore, the first component and the third component can move relatively. At this time, the third component is in the inside of the second component, and although the third component loses the constraint of the first component, the third component has completed the assembly with the second component after losing the constraint of the first component, so that the assembly of the third component and the second component does not need to be performed again after the third component loses the constraint. Therefore, the assembly device can realize the assembly of the third component and the second component.

[0008] In one of the embodiments, the material positioning assembly drives the first component to be close to one end of the material distributing assembly and the third component to be close to one end of the material distributing assembly to be axially misaligned, the first component is axially closer to the material distributing assembly than the third component, and the material distributing assembly drives the first component and the third component to move from the outside of the second component to the inside of the second component.

[0009] In one of the embodiments, the material positioning assembly comprises a material positioning part, a material positioning linkage and a material positioning drive part, the material positioning part, the material positioning linkage and the material positioning drive part are connected in sequence, the material positioning drive part drives the material positioning part to act on the third component through the material positioning linkage, the material distributing assembly comprises a clamping part and a limiting drive part connected with each other, the clamping part is used for clamping the first component, the limiting drive part drives the clamping part to move relative to the material positioning part, and the material positioning linkage is connected with the limiting drive part.

[0010] By adopting the technical scheme, the limiting drive part is connected with the clamping part through the limiting drive part and the clamping part, so that the clamping part can move along with the material positioning linkage. When the material positioning drive part drives the material positioning part to act on the third component through the material positioning linkage, the clamping part can also clamp the first component. Then, the limiting drive part drives the clamping part to move relative to the material positioning part, so that the first component moves relative to the material positioning part under the action of the clamping part, and the material positioning part acts on the third component to limit the third component from moving along with the first component, so as to realize the separation of the first component and the third component.

[0011] In one of the embodiments, the material distributing assembly further comprises a clamping linkage, a clamping drive part, a limiting linkage and a limiting part, the clamping part, the clamping linkage and the clamping drive part are connected in sequence, the clamping drive part drives the clamping part to rotate relative to the limiting part through the clamping linkage to realize that the clamping part and the limiting part clamp the first component together, the limiting part is connected with the limiting drive part through the limiting linkage, and the limiting drive part is connected with the clamping drive part.

[0012] In one of the embodiments, the clamping member comprises a driving part, a rotating part and a clamping part connected in sequence, the driving part is rotatably connected with the clamping linkage, the rotating part is rotatably connected with the limiting member, and the clamping part and the limiting member jointly clamp the first component.

[0013] In one of the embodiments, the limiting linkage is sleeved outside the clamping linkage, the positioning linkage is sleeved outside the limiting linkage, and the limiting member and the clamping member are located on the side of the positioning member away from the first component and the third component.

[0014] By adopting the above technical solution, the structure of the positioning assembly and the separating assembly is more compact, thereby further reducing the floor area of the separating assembly and the positioning assembly.

[0015] In one of the embodiments, the medical instrument production line further comprises a deforming device and an electrostatic elimination device, the deforming device is used for extruding the first component and the third component, the electrostatic elimination device is used for eliminating static electricity of the first component, the second component and the third component when passing through the deforming device and the assembling device, and the third component passes through the feeding device, the deforming device and the assembling device in sequence under the transferring of the transferring device.

[0016] By adopting the above technical solution, the first component and the third component provided by the feeding device may be deformed, thereby causing the matching degree of the shapes of the first component and the third component with the shape of the second component to be low, and thus the deforming device extrudes the first component and the third component to make the first component and the third component restore the original shapes, thereby facilitating the assembling of the assembling device. In the process of extruding the first component and the third component by the deforming device and the process of separating the first component and the third component by the assembling device, the first component and the third component will relatively move, thereby causing the first component and the third component to easily generate static electricity. The existence of the static electricity will cause the end faces of the plurality of third components separated from the first component to be misaligned, and will also affect the effect of sintering the end faces of the third component in the subsequent process. Therefore, the electrostatic elimination device is needed to eliminate the static electricity.

[0018] By adopting the technical scheme, the first component and the third component provided by the feeding device can be deformed, so that the outer shape of the first component and the third component is less matched with the outer shape of the second component, and the assembly device is difficult to assemble. When the first deforming roller, the second deforming roller and the pressing roller are distributed around the circumference of the first component, the first component is pressed by the first deforming roller, the second deforming roller and the pressing roller. Meanwhile, when at least one of the first deforming roller, the second deforming roller and the pressing roller is self-rotatable, the first deforming roller, the second deforming roller, the pressing roller and the first component can all rotate, so that the first component is pressed by the first deforming roller, the second deforming roller and the pressing roller during rotation, and the first component and the third component restore the original outer shape, facilitating the assembly of the assembly device.

[0019] In one of the embodiments, the deforming device further comprises a deforming driving member, the deforming driving member is connected with the first deforming roller, when the pressing roller moves to no longer contact the first component, the deforming driving member drives the first deforming roller to move so that the first component moves relative to the second deforming roller.

The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the related listed items.

[0040] Reference Figure 1 , the embodiment of the present application first provides an assembling device, which comprises a rack 100, a material positioning assembly 200, a material distributing assembly 300 and a material recycling assembly 400. The material positioning assembly 200 and the material distributing assembly 300 are installed on the rack 100, and the material recycling assembly 400 is located below the rack 100. The material comprises a first component, a second component and a third component. In the initial state, the third component is sleeved inside the first component, and the second component is located between the first component and the rack 100 along the axial direction of the third component. When the material is a dialyzer, the third component is a hollow fiber and the number of the third component is multiple, the first component is a film wrapping the multiple third components, and the second component is a shell containing the multiple third components. The multiple third components are constrained by the first component, and the end faces of the multiple third components are also in an aligned state. Therefore, the material positioning assembly 200, the material distributing assembly 300 and the material recycling assembly 400 are located on the same side of the axial direction of the third component. The first component and the third component can jointly enter the inside of the second component. Compared with the case that the material distributing assembly 300 and the material positioning assembly 200 are located on both sides of the axial direction of the first component and the third component, the material distributing assembly 300 and the material positioning assembly 200 are located on the same side of the axial direction of the first component and the third component, so that the floor area of the material distributing assembly 300 and the material positioning assembly 200 can be reduced.

[0041] With reference to Figure 2 and Figure 3 , the material positioning assembly 200 comprises a material positioning member 210, a material positioning linkage 220, a material positioning slide 230 and a material positioning drive 240. The material positioning linkage 220 comprises a wrapping portion 221 and a linkage portion 222, and the material positioning drive 240, the wrapping portion 221, the linkage portion 222, the material positioning slide 230 and the material positioning member 210 are sequentially connected. The linkage portion 222 is connected to the radially outer side of the material positioning member 210. The material positioning drive 240 drives the material positioning member 210 to move to abut against the third component through the material positioning slide 230, the wrapping portion 221 and the linkage portion 222, thereby playing a role in limiting the movement of the third component along with the first component.

[0042] With reference to Figure 2 , Figure 3 and Figure 4 , the material distributing assembly 300 comprises a limiting member 310, a limiting linkage 320, a limiting slide 330, a limiting drive 340, a clamping member 350, a switching member 360, a clamping linkage 370 and a clamping drive 380.

[0043] With reference to Figure 2 , Figure 3 and Figure 4 , the limiting member 310, the limiting linkage 320, the limiting slide 330 and the limiting drive 340 are sequentially connected. The limiting drive 340 drives the limiting member 310 to move through the limiting slide 330 and the limiting linkage 320. The limiting member 310 is located on the side of the material positioning member 210 connected to the linkage portion 222. The wrapping portion 221 surrounds the limiting linkage 320, and the linkage portion 222 is in an arc shape and surrounds the limiting linkage 320, so that the limiting linkage 320 is exposed to the outside from the linkage portion 222. The limiting member 310 and the linkage portion 222 are arranged in a spaced manner, so that an active space is formed between the limiting member 310 and the linkage portion 222. The limiting drive 340 is connected to the material positioning slide 230, so that the limiting drive 340 is connected to the material positioning member 210 through the material positioning slide 230, the wrapping portion 221 and the linkage portion 222.

[0044] With reference to Figure 2 , Figure 3 and Figure 4The clamping member 350, the adapter member 360, the clamping linkage 370 and the clamping driving member 380 are sequentially connected. The clamping member 350 and the adapter member 360 are each provided with two, and the two clamping members 350 and the two adapter members 360 are rotationally connected one by one, and the two adapter members 360 are rotationally connected with the clamping linkage 370 away from the end connected with the clamping driving member 380. The two clamping members 350 are located on the side of the material fixing member 210 connected with the linkage part 222. Each clamping member 350 comprises a driving part 351, a rotating part 352 and a clamping part 353 connected in sequence. The driving part 351 and the corresponding adapter member 360 are rotationally connected away from the end connected with the clamping linkage 370, the rotating part 352 and the limiting member 310 are rotationally connected, and the clamping part 353 and the limiting member 310 cooperate to clamp the first component. Therefore, the setting of the activity space allows the adapter member 360 and the clamping member 350 to rotate. The limiting member 310 is provided with a clamping groove 311, and the clamping part 353 can be clamped into the clamping groove 311, thereby enhancing the clamping effect. When the clamping driving member 380 drives the clamping linkage 370 to move towards the material fixing member 210, one end of the adapter member 360 moves with the clamping linkage 370, and simultaneously drives the driving part 351 to rotate towards the material fixing member 210, at this time the clamping part 353 rotates away from the limiting member 310 accordingly, and is in an open state. When the clamping driving member 380 drives the clamping linkage 370 to move away from the material fixing member 210, one end of the adapter member 360 moves with the clamping linkage 370, and simultaneously drives the driving part 351 to rotate away from the material fixing member 210, at this time the clamping part 353 rotates towards the limiting member 310 to clamp the clamping part 353 into the clamping groove 311, and is in a closed state. The clamping linkage 370 is sleeved in the limiting linkage 320. The structure of the material fixing assembly 200 and the material separating assembly 300 is more compact, thereby further reducing the floor area of the material separating assembly 300 and the material fixing assembly 200. The clamping driving member 380 is connected with the limiting sliding table 330, so that the clamping driving member 380 is connected with the material fixing member 210 through the limiting sliding table 330 and the limiting driving member 340. Therefore, when the clamping member 350 and the limiting member 310 clamp the first component, the limiting driving member 340 can simultaneously drive the clamping member 350 and the limiting member 310 to move relative to the material fixing member 210, so that the first component moves relative to the material fixing member 210 under the driving of the clamping member 350. The material fixing member 210 acts on the third component to limit the third component from moving with the first component, thereby realizing the separation of the first component and the third component.

[0045] Referring to Figure 1 The recovery assembly 400 is used for recovering the first component separated from the third component.

[0046] Referring to Figure 10 and Figure 11The embodiments of the present application additionally provide a medical instrument production line, comprising a feeding device, the deformation device 500, the above-mentioned assembling device 600, the detecting device 700, the rejecting device 800, the static electricity eliminating device 900 and the transferring device 1000. The feeding device is used to provide the first component, the second component and the third component. The deformation device 500 is used to extrude the first component and the third component. The detecting device 700 is used to detect whether the third component sleeved in the interior of the second component is qualified. The rejecting device 800 is used to reject the second component and the third component which are not qualified detected by the detecting device 700. In the process of extruding the first component and the third component by the deformation device 500 and the process of separating the first component and the third component by the assembling device 600, the first component and the third component will all relatively move, so that the first component and the third component are easy to generate static electricity. The existence of static electricity will on the one hand cause the end face misalignment of the third components separated from the first component, and on the other hand affect the result of sintering the end face of the third component. Therefore, the static electricity eliminating device 900 is used to eliminate the static electricity of the first component, the second component and the third component when passing through the deformation device 500 and the assembling device 600. Under the transferring of the transferring device 1000, the third component passes through the feeding device, the deformation device 500, the assembling device 600, the detecting device 700 and the rejecting device 800 in sequence, and the first component passes through the feeding device, the deformation device 500 and the assembling device 600 in sequence, and the second component passes through the assembling device 600, the detecting device 700 and the rejecting device 800 in sequence.

[0047] Reference Figure 7 and Figure 8The deforming device 500 comprises a first deforming roller 510, a second deforming roller 520, a pressing roller 530, a rotating driving member 540, a deforming driving member 550, and a force applying driving member 560. The rotating driving member 540 is connected with the first deforming roller 510, so that the rotating driving member 540 can drive the first deforming roller 510 to rotate around the axis of the first deforming roller 510. The deforming driving member 550 is connected with the second deforming roller 520, so that the deforming driving member 550 can drive the second deforming roller 520 to move close to or away from the first deforming roller 510. The force applying driving member 560 is connected with the pressing roller 530, so that the force applying driving member 560 can drive the pressing roller 530 to move close to or away from the first deforming roller 510. When the deforming driving member 550 drives the second deforming roller 520 to move close to the first deforming roller 510, the second deforming roller 520 can be moved to be flush with the first deforming roller 510. Then, the first component is placed above the first deforming roller 510 and the second deforming roller 520, and the first component is located between the first deforming roller 510 and the second deforming roller 520. The minimum distance between the first deforming roller 510 and the second deforming roller 520 is smaller than the outer diameter of the first component, so that the first deforming roller 510 and the second deforming roller 520 abut against the first component and limit the movement of the first component. Then, the force applying driving member 560 drives the pressing roller 530 to move to abut above the first component to cooperate with the first deforming roller 510 and the second deforming roller 520 to press the first component. At this time, the first deforming roller 510, the second deforming roller 520, and the pressing roller 530 are distributed around the circumference of the first component, and the minimum distance between any two of the first deforming roller 510, the second deforming roller 520, and the pressing roller 530 is smaller than the outer diameter of the first component. When the rotating driving member 540 starts to drive the first deforming roller 510 to rotate, the first component, the second deforming roller 520, and the pressing roller 530 all rotate correspondingly. When the rotating driving member 540 stops driving the first deforming roller 510 to rotate, the force applying driving member 560 starts to drive the pressing roller 530 to move away from the first component, so that the minimum distance between the pressing roller 530 and the first deforming roller 510 is greater than the outer diameter of the first component. At this time, the deforming driving member 550 drives the second deforming roller 520 to move, and the first component leaves the first deforming roller 510 under the action of the second deforming roller 520 and returns to the transferring device 1000. The first component and the third component provided by the feeding device can be deformed, so that the outer shape of the first component and the third component is less matched with the outer shape of the second component, and the assembly device 600 is difficult to assemble. When the first deforming roller 510, the second deforming roller 520, and the pressing roller 530 are distributed around the circumference of the first component, the first component is pressed by the first deforming roller 510, the second deforming roller 520, and the pressing roller 530.Meanwhile, when at least one of the first deformation roller 510, the second deformation roller 520, and the pressure roller 530 is self-rotated, the first deformation roller 510, the second deformation roller 520, the pressure roller 530, and the first member are all rotatable, so that the first member is simultaneously pressed by the first deformation roller 510, the second deformation roller 520, and the pressure roller 530 during rotation, so that the first member and the third member are restored to the original shape, facilitating assembly by the assembly device 600.

[0048] Referring to Figure 10 and Figure 11 , the detection assembly includes a signal emitter 710 and a signal receiver 720. The signal emitter 710 and the signal receiver 720 are respectively located below and above the second member. The connection lines of the signal emitter 710 and the signal receiver 720 are perpendicular to the moving direction of the third member. Therefore, when the end of the part of the third member located inside the second member exceeds the preset position, the signal emitted by the signal emitter 710 cannot be received by the signal receiver 720 when passing through the detection assembly due to obstruction, so that the unqualified product is detected by the detection assembly. When the third member and the first member move relatively, the movement of the plurality of third members cannot be consistent due to the influence of static electricity, so that the end of part of the third member exceeds the preset position. Therefore, detection by the detection assembly is required.

[0049] Referring to Figure 10 and Figure 11 , the rejection device 800 includes a rejection driving member 810 and a rejection clamping member 820. The rejection driving member 810 and the rejection clamping member 820 are connected, so that the rejection driving member 810 first drives the rejection clamping member 820 to clamp the unqualified product detected by the detection assembly, and then drives the rejection clamping member 820 to move the unqualified product away from the transfer device 1000.

[0050] Referring to Figure 1 , Figure 7 , Figure 8 and Figure 9The transferring device 1000 comprises a moving assembly 1100, a buffer assembly 1200, a releasing assembly 1300, a transferring assembly 1400 and a lifting assembly 1500. The moving assembly 1100 is used to move the medical device. The buffer assembly 1200 is used to receive the first part and the third part which are separated from the first deforming roller 510 under the action of the second deforming roller 520, and release the received first part and third part so as to return to the transferring device 1000. The releasing assembly 1300 comprises a guide 1310 and a positioning member 1320 which are connected. The guide 1310 and the positioning member 1320 are respectively located at two ends of the first part. The guide 1310 guides the first part to pass through the guide 1310. The positioning member 1320 comprises a first positioning part 1321 and a second positioning part 1322. The first positioning part 1321 sucks the first part by negative pressure, and the first positioning part 1321 and the second positioning part 1322 are close to each other to clamp the first part, so as to realize the positioning of the first part. The part of the second positioning part 1322 which is in contact with the first part is made of flexible material. The transferring assembly 1400 is used to position the second part. In order to improve the degree of automation, the lifting assembly 1500 is used to lift the first part and the third part to a position which is higher than the first deforming roller 510 and the second deforming roller 520, so that the first part and the third part fall between the first deforming roller 510 and the second deforming roller 520 under the action of gravity. In order to avoid that the first part and the third part cannot stay between the first deforming roller 510 and the second deforming roller 520 due to inertia during the falling process, the deforming device 500 further comprises a blocking member 570. The blocking member 570 is connected with the force applying driving member 560, so as to be able to move together with the pressure roller 530 under the driving of the force applying driving member 560. The lowest height of the blocking member 570 is lower than the lowest height of the pressure roller 530, so that when the minimum distance between the pressure roller 530 and the first deforming roller 510 is greater than the outer diameter of the first part, the lowest part of the blocking member 570 has already been lower than the highest point of the first part which is located between the first deforming roller 510 and the second deforming roller 520, so that the first part can both avoid the interference of the pressure roller 530 and fall between the first deforming roller 510 and the second deforming roller 520, and can also be blocked by the blocking member 570 and stay between the first deforming roller 510 and the second deforming roller 520. The medical device production line adopting the assembling device 600 can realize the automatic production of the medical device which comprises the third part and the second part which are easy to disperse after losing the constraint.

[0051] The embodiment of the present application further provides an assembling method, comprising the following steps:

[0052] Step 1: the first positioning part 1321 sucks the first part, and the second positioning part 1322 and the first positioning part 1321 clamp the first part, so that the first part and the third part are positioned by the releasing assembly 1300, and the second part is positioned by the transferring assembly 1400.

[0053] Step 2: The material positioning driving member 240 drives the material positioning member 210 to move through the second component and abut against the third component through the material positioning sliding table 230, the wrapping part 221 and the linkage part 222, and the material separating assembly 300 moves synchronously with the material positioning sliding table 230;

[0054] Step 3: The clamping driving member 380 drives the clamping member 350 to be in the open state through the clamping linkage member 370 and the adapter 360;

[0055] Step 4: The material positioning driving member 240 continues to drive the material positioning member 210 to move, and the third component moves relative to the first component under the action of the material positioning member 210, while the first component cannot move with the third component due to the action of the first positioning part 1321 and the second positioning part 1322, so that the end of the first component close to the material positioning member 210 and the end of the third component close to the material positioning member 210 are axially misaligned, and the first component is axially closer to the material separating assembly 300 than the third component, and the material separating assembly 300 moves synchronously with the material positioning sliding table 230;

[0056] Step 5: The clamping driving member 380 drives the clamping member 350 to be in the closed state to clamp the first component;

[0057] Step 6: The first positioning part 1321 no longer attracts the first component, and the second positioning part 1322 and the first positioning part 1321 move away from each other, at this time, the material releasing assembly 1300 no longer positions the first component and the third component, the material positioning driving member 240 drives the material positioning member 210 to move reversely, the material separating assembly 300 moves synchronously with the material positioning sliding table 230, thereby driving the first component to move, and the first component simultaneously drives the third component to move, so that the first component and the third component enter the inside of the second component from the outside of the second component;

[0058] Step 7: When the third component completely enters the inside of the second component, the material positioning driving member 240 no longer drives the material positioning member 210 to move, at this time, the limiting driving member 340 drives the clamping driving member 380, the clamping linkage member 370, the adapter 360 and the clamping member 350 to move away from the material positioning member 210 through the limiting sliding table 330, the limiting linkage member 320 and the limiting member 310, at this time, the first component is still clamped, and the third component cannot move with the first component due to the limitation of the material positioning member 210. Finally, the first component leaves the inside of the second component, and the limiting driving member 340 stops driving the clamping driving member 380, the clamping linkage member 370, the adapter 360 and the clamping member 350 to move;

[0059] Step 8: The material positioning driving member 240 continues to drive the material positioning member 210 to move reversely, and the material separating assembly 300 moves synchronously with the material positioning sliding table 230;

[0060] Step 9: After the material positioning member 210 is reset, the material positioning driving member 240 no longer drives the material positioning member 210 to move. The clamping driving member 380 drives the clamping member 350 to be in the open state, so that the first component is no longer clamped. The first component falls into the recycling assembly 400 under the action of its own gravity for recycling.

[0061] When the first component moves away from the inside of the second component under the action of the material distribution assembly 300, the third component cannot move with the first component due to the limitation of the material positioning assembly 200. Therefore, the first component and the third component can move relatively. At this time, the third component is in the inside of the second component, and although the third component loses the constraint of the first component, the third component has completed the assembly with the second component after losing the constraint of the first component, so that the assembly of the third component and the second component does not need to be performed again after the third component loses the constraint. Therefore, the assembly device 600 can realize the assembly of the third component and the second component.

[0062] The material distribution assembly 300 pulls the first component, and the material positioning assembly 200 pushes the third component. If the material distribution assembly 300 pushes the first component and the material positioning assembly 200 pulls the third component, and the first component and the third component are both in the inside of the second component, the material distribution assembly 300 needs to enter the inside of the second component. However, there is not enough space between the second component and the third component to allow the material distribution assembly 300 to move, so the material distribution assembly 300 cannot push the first component to move relative to the third component. In the mode that the material distribution assembly 300 pulls the first component and the material positioning assembly 200 pushes the third component, at this time, the material distribution assembly 300 and the material positioning assembly 200 do not need to enter the inside of the second component, so that the relative movement of the first component and the third component can be realized.

[0063] It can be understood that if the clamping effect formed by a single clamping part 353 and the limiting member 310 can meet the use requirement, the adapter 360 does not need to be arranged. At this time, the driving part 351 can be directly connected with the clamping linkage 370 in rotation at the end away from the clamping driving member 380.

[0064] It can be understood that if the clamping driving member 380, the clamping linkage 370 and the adapter 360 are cancelled, the matching member is arranged, and the clamping member 350 further comprises a following part connecting the rotating part 352 and the clamping part 353. The matching member is elastically connected with the limiting member 310, and the matching member is located between the limiting member 310 and the fixed material member 210. The clamping part 353 and the matching member are radially matched to realize clamping, and the following part and the matching member are axially abutted. Meanwhile, the reset member is arranged to connect the driving part 351 and the limiting member 310. At this time, when the limiting driving member 340 drives the limiting member 310 to move towards the fixed material member 210 through the limiting sliding table 330 and the limiting linkage 320, the matching member will first abut against the fixed material member 210 so as to be unable to continue to move, and the following part will continue to move, so that the following part rotates under the action of the matching member to overcome the action of the reset member, and the following part drives the clamping part 353 and the driving part 351 to rotate, so that the gap between the clamping part 353 and the matching member is increased and is in an open state, and the elastic deformation degree of the reset member is increased. When the limiting driving member 340 drives the limiting member 310 to move away from the fixed material member 210, at this time, the matching member will not start to move. The reset member acts on the driving part 351 to make the driving part 351 rotate, the elastic deformation degree of the reset member is reduced, and the driving part 351 drives the following part and the clamping part 353 to rotate, so that the following part keeps the abutting state with the axial edge of the matching member, and the gap between the clamping part 353 and the matching member is reduced and is in a closed state, realizing clamping. With the continuous movement of the limiting member 310 away from the fixed material member 210, the matching member starts to move with the limiting member 310, so that the matching member and the clamping part 353 keep the closed state.

[0065] It can be understood that the connection line of the signal transmitter 710 and the signal receiver 720 can also be not perpendicular to the moving direction of the third component, as long as the third component can move from one side of the connection line of the signal transmitter 710 and the signal receiver 720 to the other side during the movement of the transfer device 1000.

[0066] It can be understood that the medical instrument production line of the present application is not limited to the production of dialyzers, and can also be applied to the production of other medical instruments as long as the production requirements of the other medical instruments can be met.

[0067] The technical features of the above-described embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.

It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
