Figure 1A ), The fiber bundle assembler 120 is disposed downstream of the ring assembler 110 and is used to assemble the fiber bundle unit 13 with the first pre-assembler 10a into a second pre-assembler 10b (the second pre-assembler 10b is shown in Figure 1B The fiber bundle unit 13 is located inside the dialyzer body 11, and the fiber bundle unit 13 includes at least one fiber bundle 13a. Figure 1B (For illustration only; in reality, there are multiple fiber bundles 13a) and a membrane 13b, which covers the fiber bundles 13a. A membrane puller 130 is positioned downstream of the fiber bundle assembler 120 and is used to pull the membrane 13b, located within the dialyzer body 11, out of the second pre-assembled member 10b. The second pre-assembled member 10b, after removing the membrane 13b, forms the hemodialysis machine 10 (hemodialysis machine 10 is shown in...). Figure 1C Compared to manual assembly, the present invention, through the assembly equipment 100, can assemble the hemodialysis machine 10 more quickly, increasing production efficiency.
[0032] like Figures 2A to 2CAs shown, the moving module 140 includes a first mover 140A, a second mover 140B, a third mover 140C, a fourth mover 140D, a first base 140E, and a second base 140F. The first mover 140A and the second mover 140B are disposed on the first base 140E, while the third mover 140C and the fourth mover 140D are disposed on the second base 140F. The first base 140E can be mounted on a set of slide rails and is driven to slide relative to that set of slide rails. The second base 140F can be mounted on another set of slide rails and is driven to slide relative to that other set of slide rails. The first mover 140A is disposed on a first positioner 160A (the first positioner 160A is shown in the diagram). Figure 2E Above the ring assembler 110. The second mover 140B is positioned above the ring assembler 110 (the ring assembler 110 is shown in the diagram). Figure 2E ) and the first positioner 160A (the first positioner 160A is shown in Figure 2E Above the third mover 140C. The third mover 140C is positioned above the third positioner 160C (the third positioner 160C is shown in...). Figure 2E Above the second loading platform 170B. The fourth mover 140D is positioned above the second loading platform 170B (the second loading platform 170B is shown in the diagram). Figure 2E Above the dialyzer body 11, the first mover 140A, the second mover 140B, the third mover 140C, and / or the fourth mover 140D of the moving module 140 can translate and / or rotate the dialyzer body 11, the first pre-assembled member 10a, and the second pre-assembled member 10b to the next assembly station. In summary, the movers can perform translational and / or rotational movements, wherein the translational movement is achieved, for example, by the aforementioned slide rail, and the rotational movement is achieved, for example, by a steering mechanism such as a rotary cylinder. Each mover may include at least one suction nozzle, which can draw the dialyzer body 11, the first pre-assembled member 10a, the second pre-assembled member 10b, and / or the hemodialysis machine 10 through vacuum (or negative pressure) suction.
[0033] like Figure 2E , Figure 2F and Figure 2F1 As shown, a first transport module 150A can transport the dialyzer body 11 to a first positioner 160A. The first positioner 160A is used to adjust the dialyzer body 11 to a first posture, for example, the long axis of the dialyzer body 11 extends substantially parallel to the X-axis. In one embodiment, the first positioner 160A includes a stop 161 and a pressure cylinder 162. The pressure cylinder 162 is disposed opposite to the stop 161 and includes a piston rod 1621, which is used to press the dialyzer body 11 against the stop 161 to adjust the dialyzer body 11 to the first posture. The transport module described herein includes, for example, a pulley assembly and a driver, which drives the pulley assembly to rotate to transport components located thereon.
[0034] like Figure 2E , Figure 2F and Figure 2F2 As shown, the first mover 140A (the first mover 140A is illustrated in...) Figure 2A The first mover 140A is located above the first locator 160A and the first loading platform 170A, and can move back and forth between the first locator 160A and the first loading platform 170A. The first mover 140A can change the dialyzer body 11 from a first posture to (or rotate it to) a second posture and move the dialyzer body 11 in the second posture to the ring assembler 110. The second posture is, for example, a posture in which the long axis of the dialyzer body 11 extends substantially parallel to the Y-axis. In one embodiment, the first mover 140A can first rotate the dialyzer body 11 to the second posture, and then move the dialyzer body 11 in the second posture to the ring assembler 110; or, the first mover 140A can simultaneously rotate and move the dialyzer body 11. In this embodiment, the dialyzer body 11 in the second posture is placed on the first loading platform 170A. The ring assembler 110 includes a first presser 111 and a second presser 112, with a first loading platform 170A located between the first presser 111 and the second presser 112. The first presser 111 includes a pressure cylinder 110A and a picking part 110B. The picking part 110B is connected to the piston rod 110A1 of the pressure cylinder 110A and moves with the piston rod 110A1. In one embodiment, the picking part 110B is, for example, a cylindrical mechanism that picks up the temporary ring 12 through a mechanical structure such as a positioning bead; or, the picking part 110B may also be a suction nozzle that can pick up the temporary ring 12 using vacuum suction. However, as long as the temporary ring 12 can be picked up, the specific structure / mechanism of the picking part 110B is not limited in this embodiment of the invention. The second presser 112 has a similar or identical structure to the first presser 111, and will not be described in detail here.
[0035] like Figure 2E , Figure 2F and Figure 2F2 As shown, two ring storage bins 180 are respectively located adjacent to the first presser 111 and the second presser 112. Each ring storage bin 180 is used to store multiple temporary rings 12 ( Figure 2F Temporary rings 12 are not shown in the ring storage 180. The ring assembler 110 is used to pick up the recipients of these temporary rings 12; it then attaches the recipients to the end of the dialyzer body 11 to form a first pre-assembled assembly 10a (the first pre-assembled assembly 10a is shown in...). Figure 1A The picking section 110B is used to: rotate to a first position; in the first position, pick up the subject; rotate to a second position, wherein the second position is different from the first position; and, in the second position, attach the subject to the end of the dialyzer body 11, as further illustrated below.
[0036] like Figure 2E and Figure 2F As shown, the ring reservoir 180 is rotatable to convey the temporary rings 12 to below the first presser 111 and the second presser 112, facilitating the retrieval unit 110B to retrieve the temporary rings 12. The first presser 111 is rotatable about the X-axis, so that the retrieval unit 110B faces the temporary ring 12 delivered from the ring reservoir 180 (first position) to retrieve the temporary ring 12 (recipient). After retrieving the temporary ring 12 (recipient), the first presser 111 is rotatable about the X-axis, so that the retrieval unit 110B faces the dialyzer body 11 (second position), and under the drive of the pressure cylinder 110A, presses the temporary ring 12 (recipient) onto the end of the dialyzer body 11. The first presser 111 and the second presser 112 can perform the same action simultaneously or synchronously to press the two temporary rings 12 to the opposite ends of the dialyzer body 11, thereby forming the first pre-assembled member 10a (the first pre-assembled member 10a is shown in the figure). Figure 1A ).
[0037] like Figure 2E and Figure 2F As shown, the second mover 140B (the second mover 140B is illustrated in...) Figure 2A The first pre-assembled member 10a is positioned above the ring assembler 110 (or the first loading platform 170A) and the third conveying module 150C, and can move back and forth between the ring assembler 110 (or the first loading platform 170A) and the third conveying module 150C. The second mover 140B can move the first pre-assembled member 10a to the third conveying module 150C in a translational but non-rotational manner. The first pre-assembled member 10a located on the third conveying module 150C also generally remains in the second posture.
[0038] In one embodiment, the first mover 140A and the second mover 140B can move synchronously. In other words, the process of the dialyzer body 11 moving from the first positioner 160A to the ring assembler 110 (or the first loading platform 170A) and the process of the first pre-assembled stand 10a moving from the ring assembler 110 (or the first loading platform 170A) to the third conveying module 150C can be performed simultaneously / synchronously.
[0039] like Figure 2E , Figure 2F and Figure 2F3As shown, the second conveying module 150B can convey the fiber bundle unit 13 to the second positioner 160B. The second positioner 160B is used to adjust the fiber bundle unit 13 to a first posture, for example, the long axis of the fiber bundle unit 13 extends substantially parallel to the X-axis. In embodiments, the second positioner 160B includes the same or similar structure as the first positioner 160A to achieve the same or similar functions, which will not be described again here. The second positioner 160B adjusts the fiber bundle unit 13 to the first posture in the same way as the first positioner 160A, which will also not be described again here. When the fiber bundle unit 13 is adjusted to the first posture, the second conveying module 150B can convey the fiber bundle unit 13 to the lifting platform 190. The lifting platform 190 is located downstream of the second positioner 160B and is used to raise the position of the fiber bundle unit 13 so that the fiber bundle unit 13 is substantially at the same height as the first pre-assembled member 10a, so as to facilitate the assembly of the fiber bundle unit 13 and the first pre-assembled member 10a.
[0040] like Figure 2E , Figure 2F and Figure 2F5 As shown, the third positioner 160C is used to adjust the first pre-assembled member 10a to the second posture. The third positioner 160C includes the same or similar structure as the first positioner 160A to achieve the same or similar functions, which will not be described in detail here. The difference between the third positioner 160C and the first positioner 160A is that the configuration orientation of the third positioner 160C differs from that of the first positioner 160A by 90 degrees. The third mover 140C is disposed above the third conveying module 150C and the second loading platform 170B, and can move back and forth between the third conveying module 150C and the second loading platform 170B. The third mover 140C can convert the first pre-assembled member 10a from the second posture to the first posture, and move the first pre-assembled member 10a in the first posture onto the second loading platform 170B. The first posture is, for example, the posture in which the long axis of the first pre-assembled member 10a extends approximately parallel to the X-axis, while the second posture is, for example, the posture in which the long axis of the first pre-assembled member 10a extends approximately parallel to the Y-axis.
[0041] like Figure 2E , Figure 2F and Figure 2F4 As shown in the figure, the fiber bundle assembler 120 includes a push rod 122. When the first pre-assembled member 10a is placed on the second loading platform 170B, the push rod 122 pushes the fiber bundle unit 13 into the interior of the first pre-assembled member 10a, and the fiber bundle unit 13 and the first pre-assembled member 10a are assembled into the second pre-assembled member 10b.
[0042] like Figure 2E , Figure 2F and Figure 2F4As shown, the stop bar 192 presses against the end face of the fiber bundle 13a. When the stop bar 192 presses against the end face of the fiber bundle 13a, the membrane puller 130 pulls the membrane 13b out from the second pre-assembled member 10b, so that the remaining fiber bundle 13a, temporary ring 12, and dialyzer body 11 form a hemodialysis machine 10. Because the stop bar 192 presses against the end face of the fiber bundle 13a, the fiber bundle 13b is stopped and held in place by the stop bar 192 during the process of the membrane 13b being pulled out from the second pre-assembled member 10b. In one embodiment, the membrane puller 130 may include a gripper 131, which can hold the membrane 13b (the membrane 13b is shown in the figure). Figure 1C ), so as to facilitate pulling the membrane 13b.
[0043] like Figure 2E , Figure 2F and Figure 2F4 As shown, the fourth transport module 150D is positioned downstream of the second loading platform 170B. The fourth mover 140D is positioned above the second loading platform 170B and the fourth transport module 150D, and can move back and forth between the second loading platform 170B and the fourth transport module 150D. The fourth mover 140D moves the hemodialysis machine 10 onto the fourth transport module 150D. The fourth transport module 150D transports the hemodialysis machine 10 to the next assembly station to continue the next assembly step. The hemodialysis machine 10 shown in the figure can be a pre-assembled component of the final hemodialysis product.
[0044] In one embodiment, the third mover 140C and the fourth mover 140D can move synchronously. In other words, the process of the first pre-assembled member 10a moving from the third transport module 150C to the second loading platform 170B and the process of the hemodialyzer 10 moving from the second loading platform 170B to the fourth transport module 150D can be performed simultaneously / synchronously.
[0045] In summary, the hemodialysis machine assembly equipment provided by the present invention includes a ring assembler, a fiber bundle assembler, and a membrane puller. The ring assembler is used to assemble a temporary ring and the dialyzer body into a first pre-assembled component. The fiber bundle assembler is located downstream of the ring assembler and is used to assemble a fiber bundle unit and the first pre-assembled component into a second pre-assembled component. The fiber bundle unit is located inside the dialyzer body and includes a fiber bundle and a membrane, with the membrane covering the fiber bundle. The membrane puller is located downstream of the fiber bundle assembler and is used to pull the membrane located inside the dialyzer body out of the second pre-assembled component. In this way, the assembly equipment automatically assembles the temporary ring, the dialyzer body, and the fiber bundle unit, and then pulls out the membrane of the fiber bundle unit for subsequent use. The hemodialysis machine assembly equipment can achieve automated assembly of hemodialysis machines to improve assembly efficiency.
