[0002] The hemodialyzer is an important component of blood purification therapy. It uses solute exchange to remove impurities and toxins in the blood. It is mainly used to treat chronic renal failure, acute renal failure, drug poisoning and other diseases. The production process of the hemodialyzer is mainly as follows: first, the sealing ring is installed on both ends of the cylindrical dialyzer shell by snapping, and then the fiber bundle is placed in the shell. The open end of the sealing ring is connected to the aluminum foil paper for sealing it by hot pressing. Then, the glue injection machine injects glue into the interior of the shell through the glue injection port of the sealing ring. Finally, the glue-injected shell is centrifuged and dried. After the process, the sealing rings at both ends of the shell are removed, and then the end faces of the colloid formed at both ends of the shell are cut, so that the inner holes of the fiber bundle are exposed from the end faces of the colloid; however, in the prior art, the removal of the sealing rings at both ends of the dialyzer shell and the cutting of the colloid end faces still cannot be automated, and are currently mainly completed by manual combined with semi-automatic devices.

DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0018] Embodiment 1, refer to Figures 1 to 23 As shown, a cutting device for producing dialyzers comprises a first sealing rubber ring removal device 1000, a second sealing rubber ring removal device 2000 and an end surface precision cutting device 3000 which are arranged in sequence;

[0019] The first sealing rubber ring removal device 1000 includes a first conveyor line 1002, all of which are installed on the first chassis 1001, a centering mechanism 1003, a direction adjustment mechanism 1004, a first initial cutting mechanism 1005 and a first removal mechanism 1006, which are distributed in sequence along the conveying direction of the first conveyor line 1002. The first conveyor line 1002 is used to convey the dialyzer shell 4000 to be cut to the workstations where the first initial cutting mechanism 1005 and the first removal mechanism 1006 are located in sequence. The first initial cutting mechanism 1005 is used to cut off the aluminum foil at one end of the dialyzer shell 4000, and the first removal mechanism 1006 is used to remove the sealing rubber ring 4001 at the end of the aluminum foil cut off in the dialyzer shell 4000.

[0020] Since the aluminum foil is connected to the end of the corresponding sealing ring by heat sealing, it is used to seal the port of the sealing ring, which is convenient for the subsequent glue injection process. After the glue injection process is completed, there is a strong bonding force between the end face of the solidified colloid and the aluminum foil. If the aluminum foil is not cut off from the end face of the sealing ring and the colloid first, and the sealing ring is directly removed, on the one hand, due to the strong bonding force between the aluminum foil and the colloid during the glue injection process, it will cause a lot of resistance to the removal of the sealing ring, and the mechanical strength of the mechanism for removing the sealing ring is very high, and it is easy to cause irreversible damage to related mechanisms and products; on the other hand, there is a strong bonding force between the aluminum foil and the end face of the colloid. If the sealing ring is directly removed, the sealing ring will pull the aluminum foil, and the aluminum foil will generate tension on the filament bundle in the colloid, which is easy to damage the filament bundle and will directly affect the quality of the product; therefore, before removing the sealing ring, cutting the aluminum foil by the primary cutting mechanism is a crucial step, which is directly related to product quality and production efficiency.

[0021] The second sealing ring removal device 2000 comprises a first transport mechanism 2002, a second conveying line 2003, a centering mechanism 1003, a direction adjustment mechanism 1004, a second initial cutting mechanism 2004 and a second removal mechanism 2005, all of which are installed on the second chassis 2001. The first transport mechanism 2002 is used to transport the dialyzer housing 4000 in the first conveying line 1002 to the second conveying line 2003. The second conveying line 2003 is used to convey the dialyzer housing 4000 to the workstations where the second initial cutting mechanism 2004 and the second removal mechanism 2005 are located in sequence. The second initial cutting mechanism 2004 is used to cut off the aluminum foil at the other end of the dialyzer housing 4000, and the second removal mechanism 2005 is used to remove the sealing ring 4001 on the corresponding end of the dialyzer housing 4000; therefore, the sealing rings 4001 at both ends of the dialyzer housing 4000 are removed respectively by two sealing ring 4001 removal devices. The second initial cutting mechanism 2004 has the same structure and function as the first initial cutting mechanism 1005, and the second removal mechanism 2005 has the same structure and function as the first removal mechanism 1006; specifically, the overall structure of the first sealing ring removal device 1000 and the second sealing ring removal device 2000 is basically the same, except that the position and direction of the second initial cutting mechanism 2004 and the second removal mechanism 2005 are adjusted to facilitate the removal of the sealing ring 4001 at the other end of the dialyzer housing 4000, such as Figure 1 and Figure 2 shown.

[0022] The end face precision cutting device 3000 comprises a second transport mechanism 3002, a third conveying line 3003, a centering mechanism 1003, a first precision cutting mechanism 3004 and a second precision cutting mechanism 3005, all of which are installed on a third chassis 3001. The second transport mechanism 3002 is used to transport the dialyzer housing 4000 in the second conveying line 2003 to the third conveying line 3003. The third conveying line 3003 is used to transport the dialyzer housing 4000 after the sealing rings 4001 at both ends are removed. The shell 4000 is transported to the workstations where the first fine-cutting mechanism 3004 and the second fine-cutting mechanism 3005 are located in sequence. The first fine-cutting mechanism 3004 and the second fine-cutting mechanism 3005 are respectively used for fine-cutting the end faces of the colloid at both ends of the dialyzer shell 4000; wherein the first fine-cutting mechanism 3004 and the second fine-cutting mechanism 3005 have the same structure and function as the first primary cutting mechanism 1005, except that the parameters of the cutter 521 in the first fine-cutting mechanism 3004 and the second fine-cutting mechanism 3005 are adjusted accordingly to meet the needs of fine cutting.

[0023] The present invention uses the centering mechanism 1003 to center the dialyzer housing 4000 to ensure the position requirements of subsequent operations and facilitate operation control; then the dialyzer housing 4000 is rotated by the direction adjustment mechanism 1004 to determine the position of the glue injection port 4002 on the sealing rubber ring 4001, so that the directions of all the glue injection ports 4002 are consistent, so that when the dialyzer housing 4000 is clamped and positioned later, the glue injection port 4002 can be accurately placed in the preset clearance groove 5231; then the aluminum foil paper at the end of the sealing rubber ring 4001 is cut off by the initial cutting mechanism, so that the sealing rubber ring 4001 can be removed from the dialyzer later. The dialyzer housing 4000 can be easily removed; the sealing rubber ring 4001 is then removed from the end of the dialyzer housing 4000 by the removal mechanism, so that the colloid at the end of the dialyzer housing 4000 is exposed, and finally the end face of the colloid is finely cut by the fine cutting mechanism, so that the inner hole of the fiber bundle is exposed from the outer end face of the colloid, and other production process requirements can be met at the same time; therefore, the present invention can realize the automatic removal of the sealing rubber ring 4001 and the automatic cutting of the end face of the colloid, greatly improve the production efficiency, reduce the labor input, make the product quality easy to control, and provide the possibility for the entire dialyzer production line to realize fully automated production.

Specifically, the cylinder body of the clamping cylinder 302 is fixed to the corresponding connecting seat 303, the clamping plate 301 is fixed to the piston rod of the clamping cylinder 302, and a plurality of fourth guide rods 304 parallel to the piston rod of the clamping cylinder 302 are fixed to the clamping plate 301, and the fourth guide rods 304 are slidably installed on the corresponding ; it is worth mentioning that, due to the need to make avoidance design for other mechanisms, the centering mechanism 1003 is not distributed in a completely symmetrical form on both sides of the first conveyor line 1002; when the centering mechanism 1003 is working, the dialyzer shells 4000 to be processed are transported to the first conveyor line 1002 through the third transport mechanism 1007. In this embodiment, the number of dialyzer shells 4000 transported at a time is four. Of course, other numbers of dialyzer shells 4000 can be set for single transport according to actual production needs. The four dialyzer shells 4000 are respectively placed on four consecutive carriers 203 on the first conveyor line 1002, and the four dialyzer shells 4000 are just located between the two clamping plates 301, such as Figure 4 As shown, the length direction of the dialyzer housing 4000 is perpendicular to the movement direction of the conveying chain 202, and then, the two clamping plates 301 move toward each other synchronously under the drive of the corresponding clamping cylinders 302, so as to clamp the four dialyzer housings 4000 synchronously and thus realize the centering positioning of the dialyzer housings 4000.

[0026] In a specific embodiment of the present invention, Figure 1 , Figure 2 and Figures 5 to 9As shown, the direction adjustment mechanism 1004 includes a first lifting component and an adjusting component used in conjunction with each other; the number of the first lifting components is two and they are symmetrically installed on both sides of the frame 201, the first lifting component includes a first lifting cylinder 402 and a plurality of follower wheel groups 406, the number of the follower wheel groups 406 in this embodiment is four, the first lifting cylinder 402 is vertically arranged upward and its cylinder body is fixed on a first fixed plate 404, the first fixed plate 404 is fixed on the corresponding side of the frame 201, a first lifting frame 403 is fixed on the piston rod of the first lifting cylinder 402, and the first lifting frame 403 is vertically slidably installed on a first guide rail 405 fixed to the first fixed plate 404, and the plurality of follower wheels The groups 406 are installed on the first lifting frame 403 at equal intervals horizontally along the moving direction of the conveyor chain 202, and the spacing between two adjacent follower wheel groups 406 is equal to the spacing between two adjacent carriers 203. The follower wheel group 406 includes a wheel frame 407 installed on the first lifting frame 403 and two follower wheels 408 rotatably installed on the wheel frame 407. A plurality of first guide rods 409 extending vertically downward and slidably installed on the first lifting frame 403 are fixed on the wheel frame 407. A first retaining ring 410 is fixed at the lower end of the first guide rod 409 to prevent it from slipping off the first lifting frame 403. A buffer spring 411 is also mounted on the outside of the first guide rod 409 at both ends, which respectively abuts against the first lifting frame 403 and the wheel frame 407. Figure 8 and Fig. 9 shown.

[0027] The adjustment component includes an extension frame 413 fixed on the first chassis 1001 and a plurality of drive rollers 414 rotatably mounted on the extension frame 413 at equal intervals. The drive rollers 414 are located directly above the conveyor chain 202 and correspond one-to-one to the follower wheel group 406. The axis of the drive roller 414 and the axis of the follower wheel 408 are both horizontally arranged and parallel to each other. One end of the drive roller 414 is connected to the output shaft of the adjustment motor 416 through the first synchronous belt 415 to form a belt drive.

[0028] When the direction adjustment mechanism 1004 is working;

[0029] First, after being centered and positioned by the centering mechanism 1003, the four dialyzer housings 4000 are driven by the conveying chain 202 to the position where the direction adjustment mechanism 1004 is located, that is, the four dialyzer housings 4000 are just located above the four follower wheel groups 406 in the first lifting assembly. The follower wheel groups 406 move vertically upward under the drive of the first lifting cylinder 402, and the follower wheel groups 406 lift the corresponding dialyzer housings 4000 to a set height through the corresponding two follower wheels 408.

When the optical fiber sensor 418 detects the glue injection port 4002, the driving roller 414 stops rotating, so that the glue injection port 4002 stays at the preset position. In this embodiment, the preset position of the glue injection port 4002 is vertically downward. After the position adjustment of the glue injection port 4002 is completed, the scanning module can just scan and read the information code on the dialyzer shell 4000 clamped by the corresponding driving roller 414, and enter the read information into the control system, and then the dialyzer shell 4000 is dropped onto the original carrier 203, and the next step is to enter the initial cutting station.

The makeshift groove 5231 is used to accommodate the glue injection port 4002 on the sealing rubber ring 4001.

[0036] When the first initial cutting mechanism 1005 is working;

[0037] First, the four dialyzer housings 4000 after direction adjustment are moved to the position where the first initial cutting mechanism 1005 is located under the drive of the conveyor chain 202, that is, the four dialyzer housings 4000 are located just above the four first supporting card plates 526 in the second lifting assembly 525, and the first supporting card plates 526 move vertically upward under the drive of the second lifting cylinder 528, and the first supporting card plates 526 lift the corresponding dialyzer housings 4000 to a set height through their card slots, so that the dialyzer housings 4000 are completely separated from the carrier 203 on the conveyor chain 202, and the dialyzer housings 4000 are just horizontally corresponding to the positioning holes 524 on the corresponding positioning blocks 523;

[0038] Then, the side pressure cylinder 503 drives the pressing block 504 to move toward the first conveying line 1002, and makes the four pressing blocks 504 press against the ends of the corresponding four dialyzer housings 4000 respectively, and the side pressure cylinder 503 continues to extend and gradually makes the other end of the dialyzer housing 4000 accurately inserted into the positioning hole 524 of the corresponding positioning block 523, and clamps the dialyzer housing 4000 between the positioning block 523 and the pressing block 504. At this time, the glue injection port 4002 on the sealing rubber ring 4001 inserted into the positioning hole 524 is just located in the yield groove 5231 provided on the corresponding positioning block 523, and the end of the dialyzer housing 4000 inserted into the positioning hole 524 is the end to be cut, and the end face of the end to be cut passes through the corresponding positioning hole 524;

The cut waste automatically falls into the collection cylinder provided in the first chassis 1001;

[0040] After the aluminum foil is cut, the side pressure cylinder 503 drives the pressing block 504 to return to the initial waiting position, so that the dialyzer housing 4000 is released from being clamped. After that, the pull-back cylinder 508 and the lifting cylinder 506 jointly drive the positioning card plate 512 to move, so that the card slot of the positioning card plate 512 is pressed on the dialyzer housing 4000 between the first supporting card plate 526 and the sealing rubber ring 4001, and the sealing rubber ring 4001 is located between the first supporting card plate 526 and the limiting plate 513. The sealing rubber ring referred to in this step 4001 is the sealing ring 4001 close to one end of the pressure block 504, and then the retracting cylinder 508 retracts to pull the corresponding end of the dialyzer shell 4000 out of the positioning hole 524 of the positioning block 523, and pull the dialyzer shell 4000 back to the set position, then the positioning card plate 512 returns to the initial waiting position, and finally, the first supporting card plate 526 returns to the initial waiting position, and the dialyzer shell 4000 is dropped onto the original carrier 203, and the next step is to enter the sealing ring 4001 removal station.

[0041] In a specific embodiment of the present invention, Figure 1 , Figure 2 and Figure 20 to Figure 22 As shown, the first removal mechanism 1006 includes a pressure plate 601 and a push column 605 respectively used to clamp on both ends of the dialyzer housing 4000, a paddle plate 611 used to remove the sealing ring 4001, and a third lifting component 618 used to lift the dialyzer housing 4000; the paddle plate 611, the push column 605 and the cutting component 514 are all located on the same side of the first conveying line 1002.

[0042] There are two third lifting assemblies 618, which are symmetrically installed on both sides of the frame 201. The third lifting assembly 618 includes a third lifting cylinder and multiple second supporting pallets. The third lifting cylinder is vertically upwardly arranged and its cylinder body is fixed on a third fixed plate. The third fixed plate is fixed on the corresponding side of the frame 201. A third lifting frame is fixed on the piston rod of the third lifting cylinder, and the third lifting frame is vertically slidably installed on a fifth guide rail fixed to the third fixed plate. Multiple second supporting pallets are horizontally fixed on the third lifting frame at equal intervals along the moving direction of the conveying chain 202. In this embodiment, there are four second supporting pallets, and the spacing between two adjacent second supporting pallets is equal to the spacing between two adjacent carriers 203. Each of the second supporting pallets is provided with a card slot with an opening facing upward and used to position and support the dialyzer shell 4000. The structure and function of the third lifting assembly 618 and the second lifting assembly 525 are the same, so their specific structures are no longer shown in separate drawings.

[0043] The pressure plate 601 is placed sideways and a plurality of third guide rods 602 extending horizontally outward are fixed on the side away from the first conveyor line 1002.

[0044] There are multiple top columns 605, which correspond to the second supporting card plates one by one. In this embodiment, there are four top columns 605, which are all cylindrical. Each top column 605 is connected to a first driving assembly that drives it to move. The first driving assembly includes a top pressure cylinder 608 and a translation seat 607. One end of the top column 605 is fixed on the translation seat 607, and the free end of the top column 605 extends along the movement direction of the vertical conveying chain 202 toward the direction of the first conveying line 1002. A metal sensor 606 for detecting aluminum foil is also embedded and installed at the free end of the top column 605. The metal sensor 606 is buried inside the top column 605, and the detection end of the metal sensor 606 is connected to the outside world through a through hole at the end of the top column 605. When the end of the push column 605 contacts the end of the dialyzer housing 4000 from which the sealing ring 4001 is to be removed, if the aluminum foil at the corresponding end is not cut off in the previous step, the metal sensor 606 will detect the presence of metal and form a feedback signal, indicating that the aluminum foil at this end has not been cut off, so that the lever does not perform the action of removing the sealing ring 4001 on the dialyzer housing 4000, and the translation seat 607 is slidably installed on the sixth guide rail 609 fixed to the seat plate 610, wherein the seat plate 610 is fixed on the first chassis 1001, and the cylinder body of the top pressure cylinder 608 is fixed on the seat plate 610, and the piston rod of the top pressure cylinder 608 is connected to the translation seat 607, and the top pressure cylinder 608 drives the translation seat 607 to slide along the sixth guide rail 609.

[0045] The number of the paddle plates 611 is multiple and corresponds to the second supporting card plates one by one. In this embodiment, the number of the paddle plates 611 is four, and each of the paddle plates 611 is connected to a second driving assembly that drives it to move; the second driving assembly includes a sliding frame 612, a push-pull cylinder 615 and a downward pressing cylinder 613. The paddle plate 611 is vertically arranged and has a downward opening at its lower end for removing the sealing rubber ring 4001. The paddle plate 611 is vertically slidably installed on the seventh guide rail 614 fixed to the sliding frame 612, and The upper end of the paddle plate 611 is connected to the piston rod of the downward-pressing cylinder 613, which is vertically arranged and has its cylinder body fixed on the sliding frame 612, and the sliding frame 612 is horizontally slidably installed on the eighth guide rail 616 fixed to the table 617, and the sliding frame 612 is also connected to the piston rod of the push-pull cylinder 615, which is arranged parallel to the eighth guide rail 616 and has its cylinder body fixed on the table 617, and the push-pull cylinder 615 drives the sliding frame 612 to slide horizontally along the eighth guide rail 616.

[0046] When the first removal mechanism 1006 is working;

[0047] First, the four dialyzer shells 4000 processed by the initial cutting station are moved to the station where the first dismantling mechanism 1006 is located under the drive of the conveyor chain 202, that is, the four dialyzer shells 4000 are located just above the four second supporting card plates in the third lifting assembly 618, and the second supporting card plates move vertically upward under the drive of the third lifting cylinder. The second supporting card plates lift the corresponding dialyzer shells 4000 to a set height through their card slots, so that the dialyzer shells 4000 are completely separated from the carrier 203 on the conveyor chain 202, and the dialyzer shells 4000 are coaxial with the top column 605;

[0048] Secondly, the pressure plate 601 and the top column 605 are driven by the corresponding cylinders to move synchronously towards each other, thereby clamping the dialyzer housing 4000 lifted by the second supporting card plate, that is, the pressure plate 601 pushes on one end of the four dialyzer housings 4000 lifted by the third lifting assembly 618 at the same time, and the four top columns 605 push on the other ends of the four dialyzer housings 4000 respectively, and the end of the dialyzer housing 4000 pushed by the top column 605 is also the end of the aluminum foil cut off in the previous process. At this time, the metal conductor in the top column 605 is The sensor 606 works to detect whether the aluminum foil at the end of the dialyzer housing 4000 is missed. If missed, the metal sensor 606 will detect the presence of metal and generate a feedback signal, indicating that the aluminum foil at this end is not cut off, so that the lever will not perform the action of removing the sealing rubber ring 4001 on the dialyzer housing 4000 in the next step. Because when the aluminum foil is not cut off, the force of the connection between the sealing rubber ring 4001 and the dialyzer housing 4000 is relatively large, and if the action of removing the sealing rubber ring 4001 is directly performed, the device is easily damaged;

[0049] Then, when the metal sensor 606 in the top column 605 does not show a feedback signal, the push-pull cylinder 615 and the pressing cylinder 613 jointly drive the paddle 611 corresponding to the metal sensor 606 to move, so that the card slot of the paddle 611 extends into between the second supporting card plate and the sealing rubber ring 4001, and the edge of the card slot on the paddle 611 corresponds to the inner end surface of the sealing rubber ring 4001. The sealing rubber ring 4001 referred to in this step is the sealing rubber ring 4001 at the end where the top column 605 is located. 1, and then the push-pull cylinder 615 retracts and drives the paddle plate 611 to move, and the moving paddle plate 611 pushes against the inner end surface of the corresponding sealing rubber ring 4001 through the edge of its card slot, and then gradually removes the corresponding sealing rubber ring 4001 from the dialyzer housing 4000, and the completely removed sealing rubber ring 4001 automatically falls into the collection box set inside the first chassis 1001, and then the pressure plate 601 and the top column 605 are both returned to the initial waiting position, and the removal of the sealing rubber ring 4001 is completed.

[0050] After the first rubber ring removal device 1000 removes the rubber ring 4001 at one end of the dialyzer housing 4000, the first transport mechanism 2002 transports the four dialyzer housings 4000 at the station where the first removal mechanism 1006 is located to the station where the centering mechanism 1003 in the second rubber ring removal device 2000 is located, and in this process, the unqualified dialyzer housings 4000 are placed in the first temporary storage box 1008 arranged between the first chassis 1001 and the second chassis 2001, and the second rubber ring removal device 2000 adopts the same method as the first rubber ring removal device 1000 to remove the rubber ring 4001 at the other end of the dialyzer housing 4000, and the dialyzer housing 4000 is After the sealing rings 4001 at both ends of the dialyzer shell 4000 are removed, the second transport mechanism 3002 transports the dialyzer shell 4000 in the second sealing ring removal device 2000 to the workstation where the centering mechanism 1003 in the end face precision cutting device 3000 is located, and in the process, the unqualified dialyzer shell 4000 is placed in the second temporary storage box 2006 arranged between the second chassis 2001 and the third chassis 3001, and finally the end faces of the colloid at both ends of the dialyzer shell 4000 are precision cut by the first precision cutting mechanism 3004 and the second precision cutting mechanism 3005 respectively. After the cutting is completed, the dialyzer shell 4000 is transported off the production line by the fourth transport mechanism 3006 arranged on the third chassis 3001.

[0051] like Fig.23 As shown, the first transport mechanism 2002 includes a manipulator 701 and a grabbing assembly installed on the working end of the manipulator 701, the grabbing assembly includes a mounting plate 702 and four gripping cylinders 703 distributed on the mounting plate 702 in a straight line and at equal intervals, the spacing between two adjacent gripping cylinders 703 is equal to the spacing between two adjacent carriers 203, the cylinder body of the gripping cylinder 703 is fixed on the mounting plate 702, and the two piston rods of the gripping cylinder 703 are fixed with symmetrically arranged gripping jaws 704, the two gripping jaws 704 are driven by the gripping cylinder 703 to move synchronously toward or in opposite directions, thereby realizing the gripping or placing down of the dialyzer housing 4000, and at the same time, the structures and functions of the second transport mechanism 3002, the third transport mechanism 1007 and the fourth transport mechanism 3006 are the same as those of the first transport mechanism 202.
