Description

Technical Field

[0001] This utility model relates to the field of automatic packaging technology for infusion sets, and more specifically, to a flow regulator position adjustment device for infusion set products. Background Technology

[0002] Disposable infusion sets are common medical consumables used for intravenous infusions. A typical disposable infusion set consists of an intravenous needle, needle holder, infusion tubing, medication filter, flow regulator, drip chamber, stopper inserter, endotracheal tube, and air filter. The overall length of a disposable infusion set is relatively long. The flow regulator consists of a housing and rollers; the rollers are connected to the housing, and the housing has channels for the tubing to pass through.

[0003] Regarding the production process of disposable infusion sets, the packaging process of the finished disposable infusion sets is completed by automatic packaging equipment. The basic operation sequence of the automatic packaging process is: (1) feeding, (2) making the infusion set in a straight line, (3) transferring the straight infusion set to the winding device, (4) the winding device winding the straight infusion set into a roll, and (5) placing the roll of infusion set into a packaging bag. For the specific structure of the existing automatic packaging equipment, please refer to the invention patent application with publication number CN111348279A, entitled "Automatic Material Picking, Winding and Bagging Device for Infusion Sets". Regarding operation step (4), it is required that the distance between the flow regulator on the straight infusion set and the intravenous needle seat be fixed (sometimes a position close to the intravenous needle seat is required).

[0004] Therefore, how to fix the distance between the flow regulator on the infusion set and the vein needle seat is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] This application aims to solve the technical problem of fixing the distance between the flow regulator on the infusion set and the intravenous needle seat in the automatic packaging process of infusion sets, and provides a flow regulator position adjustment device for infusion set products.

[0006] This disclosure provides a flow regulator position adjustment device for an infusion set product, including an X-axis linear module, a first Z-axis linear module, a second Z-axis linear module, a first clamping mechanism, a second clamping mechanism, and a third clamping mechanism. The third clamping mechanism is located to the right of the second clamping mechanism. The first Z-axis linear module enables the first clamping mechanism to move along the Z-axis, and the second Z-axis linear module enables the second clamping mechanism to move along the Z-axis. The X-axis linear module enables the first clamping mechanism to move along the X-axis, and the X-axis linear module enables the second clamping mechanism to move along the X-axis. The first clamping mechanism includes a first driving unit and at least one first gripper connected to the first driving unit. The first gripper includes a clamping part one and a clamping part two. The inner side of the clamping part one is provided with a recess, and the lower end of the clamping part one is provided with a lifting part. The inner side of the clamping part two is provided with a recess, and the lower end of the clamping part two is provided with a lifting part. When the clamping part one and the clamping part two are closed, the recess on the clamping part one and the recess on the clamping part two form a receiving space, and the lifting part at the lower end of the clamping part one and the lifting part at the lower end of the clamping part two are connected together. The second clamping mechanism includes a second drive unit and at least one second gripper connected to the second drive unit. The second gripper includes a first clamping part and a second clamping part. The first clamping part of the second gripper has a recess on its inner side and a lifting part at its lower end. The second clamping part of the second gripper also has a recess on its inner side and a lifting part at its lower end. When the first clamping part and the second clamping part of the second gripper are closed, the two recesses on the first clamping part and the second clamping part form an accommodating space, and the two lifting parts at the lower ends of the first clamping part and the second clamping part are joined together. The third clamping mechanism includes a third drive unit and at least one third gripper connected to the third drive unit. The third gripper includes a first clamping part and a second clamping part. The inner side of the first clamping part is provided with a recess, and the lower end of the first clamping part is provided with a lifting part. The inner side of the second clamping part is provided with a recess, and the lower end of the second clamping part is provided with a lifting part. When the first clamping part and the second clamping part are closed, the recess on the first clamping part and the recess on the second clamping part form a receiving space, and the lifting part at the lower end of the first clamping part and the lifting part at the lower end of the second clamping part are joined together. The process of adjusting the position of the flow regulator on an infusion set is as follows: Step (1): The first Z-axis linear module lowers the first clamping mechanism from its initial position along the Z-axis to the infusion set to be processed, and the second Z-axis linear module lowers the second clamping mechanism from its initial position along the Z-axis to the infusion set to be processed. The first and second grippers close to clamp the tubing of the infusion set to be processed. The tubing is located in the receiving space of the first gripper and the receiving space of the second gripper. Next, the first Z-axis linear module raises the first clamping mechanism to its initial position, and the second Z-axis linear module raises the second clamping mechanism to its initial position. Step (2): The X-axis linear module moves the first clamping mechanism to the left and the second clamping mechanism to the right. The first gripper moves to the left and the second gripper moves to the right. The first gripper moves to the left endpoint P and the second gripper moves to the right endpoint Q. The infusion set is straightened. The first gripper abuts against the drip chamber of the infusion set, and the second gripper abuts against the large end of the flow regulator of the infusion set. The small end of the flow regulator abuts against the vein needle seat. The distance between the left endpoint P and the right endpoint Q is L. Step (3): The third clamping mechanism moves to clamp the small end of the flow regulator with the third jaw. The small end of the flow regulator is located in the receiving space formed by the two recesses of the third jaw. Next, the second jaw opens, and then the second Z-axis linear module raises the second clamping mechanism to move the second jaw away from the tubing of the infusion set. Step (4): The X-axis linear module moves the second gripper to the right above the flow regulator, and the Z-axis linear module lowers the second gripper to the position of the flow regulator, so that the second gripper clamps the flow regulator. Step (5): The X-axis linear module moves the second clamping mechanism to the left, and the second gripper moves the flow regulator a certain distance to the left and then stops; next, the second gripper opens; next, the second Z-axis linear module raises the second gripper and moves the second gripper away from the flow regulator. Step (6): Open the first and third grippers to release the infusion set product.

[0007] Preferably, in step (2), the first gripper and the second gripper start moving simultaneously, and the second gripper reaches the right end point Q at the same time as the first gripper reaches the left end point P.

[0008] Preferably, in step (2), the first gripper and the second gripper start moving simultaneously, with the second gripper reaching the right endpoint Q first and the first gripper reaching the left endpoint P later.

[0009] Preferably, in step (2), the first gripper and the second gripper start moving simultaneously, with the first gripper reaching the left endpoint P first and the second gripper reaching the right endpoint Q later.

[0010] Preferably, after the first gripper and the second gripper start moving simultaneously, the second gripper moves to the right and stops at position point S, the first gripper first reaches the left endpoint P, and then the second gripper continues to move to the right, and then the second gripper reaches the right endpoint Q.

[0011] Preferably, the distance between position point S and the right endpoint Q is one-ninth of the distance L.

[0012] Preferably, the speed of the second gripper moving from position point S to the right end point Q is V2, and the speed of the first gripper moving from the starting point to the left end point P is V1, where V2 < V1.

[0013] Preferably, the flow regulator position adjustment device of the infusion set product further includes a Y-axis linear module, which is used to move the first clamping mechanism and the third clamping mechanism along the Y-axis direction.

[0014] Preferably, the flow regulator position adjustment device of the infusion set product further includes a third Z-axis linear module, which is used to move the third clamping mechanism along the Z-axis direction.

[0015] More preferably, the third clamping mechanism further includes a translation module, which is used to cause the third driving unit to translate along the X direction, thereby causing the third gripper to translate along the X direction.

[0016] The beneficial effect of this disclosure is that it automatically adjusts the position of the flow regulator on the infusion set product, thereby fixing the distance between the flow regulator on the infusion set product and the vein needle hub, and the specific distance can be set according to the actual situation.

[0017] The flow regulator is adjusted by moving away from the vein needle hub, with the larger end in front and the smaller end behind, as it moves along the tubing.

[0018] It can reliably adjust the position of the flow regulator to ensure the quality and efficiency of the operation.

[0019] When the rollers in the flow regulator compress the tubing, the flow regulator can be easily adjusted to the correct position for the infusion set product being processed.

[0020] Further features and aspects of this disclosure will be clearly described in the following detailed description with reference to the accompanying drawings. Attached Figure Description

[0024] The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] The specific embodiments described below are merely preferred embodiments of this application, and the scope of protection of this application is not limited thereto. Those skilled in the art can make modifications or variations based on the principles, concepts, and spirit of this application, and the resulting technical solutions should all be covered within the scope of protection of this application.

[0026] like Figure 1-7As shown, the flow regulator position adjustment device includes a feeding device 100, an X-axis linear module 200, a Y-axis linear module 300, a first Z-axis linear module 400, a second Z-axis linear module 500, a first clamping mechanism 600, a second clamping mechanism 700, a third clamping mechanism 800, and a third Z-axis linear module 900. The Y-axis linear module 300 is mounted on a frame. The X-axis linear module 200 is connected to the Y-axis linear module 300, and the first Z-axis linear module 400 is connected to the X-axis linear module 200. The second Z-axis linear module 500 is connected to the X-axis linear module 200, and the third Z-axis linear module 900 is connected to the X-axis linear module 200. The third Z-axis linear module 900 is located to the right of the second Z-axis linear module 500. The first clamping mechanism 600 is connected to the first Z-axis linear module 400, the second clamping mechanism 700 is connected to the second Z-axis linear module 500, and the third clamping mechanism 800 is connected to the third Z-axis linear module 900. The third clamping mechanism 800 is located to the right of the second clamping mechanism 700. The movement of the Y-axis linear module 300 drives the entire X-axis linear module 200 to move along the Y-axis, thereby causing the first clamping mechanism 600, the second clamping mechanism 700, and the third clamping mechanism 800 to move along the Y-axis. The movement of the X-axis linear module 200 causes the first Z-axis linear module 400, the second Z-axis linear module 500, and the third Z-axis linear module 900 to move along the X-axis, thereby causing the first clamping mechanism 600, the second clamping mechanism 700, and the third clamping mechanism 800 to move along the X-axis. The movement of the first Z-axis linear module 400 causes the first clamping mechanism 600 to move along the Z-axis, the movement of the second Z-axis linear module 500 causes the second clamping mechanism 700 to move along the Z-axis, and the movement of the third Z-axis linear module 900 causes the third clamping mechanism 800 to move along the Z-axis. The feeding device 100 is located below the X-axis linear module 200.

[0027] like Figure 1 , 2As shown in Figures 3, 8, and 9, the first clamping mechanism 600 includes a first support 601, a first drive unit 602, and a first gripper 603. The first drive unit 602 is mounted on the first support 601, and the first gripper 603 is connected to the first drive unit 602. The first drive unit 602 can cause the first gripper 603 to close or open. The first gripper 603 includes a gripping part 603-1 and a gripping part 603-2. The inner side of the gripping part 603-1 is provided with a recess 603-1-1, and the lower end of the gripping part 603-1 is provided with a lifting part 603-1-2. The inner side of the gripping part 603-2 is provided with a recess 603-2-1, and the lower end of the gripping part 603-2 is provided with a lifting part 603-2-2. When the gripping part 603-1 and the gripping part 603-2 are closed, the recesses 603-1-1 and 603-2-1 form a receiving space, in which the tubing of the infusion set can move. The lifting parts 603-1-2 and 603-2-2 work together to lift the tubing upward, thereby preventing the tubing from detaching from the gripper and falling. The number of first grippers 603 is at least one. The figure shows multiple first grippers 603 arranged in a straight line. When multiple first grippers are used, as shown in the figure, the first drive unit 602 specifically includes a first drive module, a rear sliding plate 602-1, a front sliding plate 602-2, and a guide rail assembly 602-3. The first drive module is typically a finger cylinder or an electric finger. The rear sliding plate 602-1 and the front sliding plate 602-2 are respectively connected to two fingers of the finger cylinder (or electric finger). The guide rail... Component 602-3 is connected between the rear sliding plate 602-1 and the front sliding plate 602-2. The first gripping part 603-1 of each first gripper 603 is connected to the front sliding plate 602-2, and the second gripping part 603-2 of each first gripper 603 is connected to the rear sliding plate 602-1. When the finger cylinder (or electric finger) is activated, the rear sliding plate 602-1 and the front sliding plate 602-2 can slide relative to each other, thereby causing the rear sliding plate 602-1 and the front sliding plate 602-2 to drive each gripper to close or open. Figure 9 This indicates that each first gripper is in the open state. One advantage of setting multiple first grippers 603 in the above manner is that the distance between two adjacent first grippers is smaller, which ensures that the distance between two adjacent infusion set products is small when operating multiple infusion set products.

[0028] If only one first gripper 603 is provided, then the rear sliding plate 602-1, the front sliding plate 602-2 and the guide rail assembly 602-3 can be omitted, and the gripping part 603-1 and the gripping part 603-2 of the first gripper 603 can be directly connected to the two fingers of the finger cylinder (or electric finger).

[0029] The first bracket 601 is mounted on the slider of the first Z-axis linear module 400.

[0030] like Figure 1 , 2 As shown in Figures 3, 8, and 10, the second clamping mechanism 700 includes a second support 701, a second drive unit 702, and a second gripper 703. The second drive unit 702 is mounted on the second support 701, and the second gripper 703 is connected to the second drive unit 702. The second drive unit 702 can cause the first gripper 603 to close or open. The second gripper 703 includes a first gripping part 703-1 and a second gripping part 703-2. The inner side of the first gripping part 703-1 is provided with a recess 703-1-1, and the lower end of the first gripping part 703-1 is provided with a lifting part 703-1-2. The inner side of the second gripping part 703-2 is provided with a recess 703-2-1, and the lower end of the second gripping part 703-2 is provided with a lifting part 703-2-2. When the first gripping part 703-1 and the second gripping part 703-2 are closed, the recess 703-1-1 and the recess 703-2-1 form a receiving space, in which the tubing of the infusion set can move. The lifting part 703-1-2 and the lifting part 703-2-2 work together to lift the tubing upward, thereby preventing the tubing from detaching from the gripper and falling. The number of second grippers 703 is at least one. The figure shows multiple second grippers 703 arranged in a straight line. When multiple second grippers are provided, the specific structure is basically the same as the structure of the first gripping mechanism 600 with multiple first grippers. That is, the second drive unit 702 includes a second drive module, a rear sliding plate, a front sliding plate, and a guide rail assembly. The second drive module is usually a finger cylinder or an electric finger. The rear sliding plate and the front sliding plate are respectively connected to two fingers of the finger cylinder (or electric finger). The guide rail assembly is connected between the rear sliding plate and the front sliding plate. The first gripping part of each second gripper is connected to the front sliding plate, and the second gripping part of each second gripper is connected to the rear sliding plate. Figure 10 The second gripper is shown to be in the open state. If only one second gripper 703 is provided, then the rear sliding plate, front sliding plate and guide rail assembly can be omitted, and the gripping part 1 703-1 and gripping part 2 703-2 of the second gripper 703 can be directly connected to the two fingers of the finger cylinder (or electric finger).

[0031] The second bracket 701 is mounted on the slider of the second Z-axis linear module 500.

[0032] like Figure 1 , 3As shown in Figures 7 and 11, the third clamping mechanism 800 includes a third support 801, a translation module 802, a third drive unit 803, and a third gripper 804. The translation module 802 is connected to the third support 801, the third drive unit 803 is connected to the third support 801, and the third gripper 804 is connected to the third drive unit 803. The third drive unit 803 is used to open or close the third gripper 804. The third gripper 804 includes a first gripping part 804-1 and a second gripping part 804-2. The inner side of the first gripping part 804-1 is provided with a recess 804-1-1, and the lower end of the first gripping part 804-1 is provided with a lifting part 804-1-2. The inner side of the second gripping part 804-2 is provided with a recess 804-2-1, and the lower end of the second gripping part 804-2 is provided with a lifting part 804-2-2. When the first gripping part 804-1 and the second gripping part 804-2 are closed, the recess 804-1-1 and the recess 804-2-1 form a receiving space, in which the tubing of the infusion set can move. The lifting part 804-1-2 and the lifting part 804-2-2 work together to lift the tubing upward, thereby preventing the tubing from detaching from the gripper and falling. The translation module 802 (which can be a cylinder) can cause the third drive unit 803 to translate in the X direction, thereby causing the third gripper 804 to translate in the X direction. The number of third grippers 804 is at least one. The figure shows multiple third grippers 804 arranged in a straight line. With multiple third grippers, as shown in the figure, the third drive unit 803 specifically includes a third drive module, a front slide plate 803-1, a rear slide plate 803-2, and a guide rail assembly. The third drive module is typically a finger cylinder or an electric finger. The front slide plate 803-1 and the rear slide plate 803-2 are respectively connected to two fingers of the finger cylinder (or electric finger). The guide rail assembly connects the front slide plate 803-1 and the rear slide plate 803-2. The first gripping part 804-1 of each third gripper 804 is connected to the rear slide plate 803-2, and the second gripping part 804-2 of each third gripper 804 is connected to the front slide plate 803-1. When the finger cylinder (or electric finger) is activated, the rear slide plate 803-2 and the front slide plate 803-1 slide relative to each other, thereby causing the rear slide plate 803-2 and the front slide plate 803-1 to close or open each third gripper. Figure 11 This indicates that each third gripper is in the open position. One advantage of setting multiple third grippers in this manner is that it allows for a smaller distance between adjacent third grippers, ensuring a smaller distance between adjacent infusion sets when operating multiple infusion sets.

[0033] If only one third gripper 804 is set, then the front slide plate 803-1, the rear slide plate 803-2, and the guide rail assembly can be omitted, and the first gripping part 804-1 and the second gripping part 804-2 of the third gripper 804 can be directly connected to the two fingers of the finger cylinder (or electric finger).

[0034] The third bracket 801 is installed on the slider of the third Z-axis linear module 900.

[0035] When multiple third grippers 804, multiple second grippers 703, and multiple first grippers 603 are provided, the number of third grippers 804, second grippers 703, and first grippers 603 are equal.

[0036] The following describes the operation process of the above-mentioned flow regulator position adjustment device: Step S1, refer to Figure 12 and 13 The top of the feeding device 100 is equipped with multiple support frames 100-1. Each support frame 100-1 has two grooves on its front side and two grooves on its rear side. The two grooves on the front side correspond to the two grooves on the rear side, meaning that two infusion sets can be suspended on one support frame 100-1. Figure 12 and 13 As can be seen, an infusion set is suspended on the grooves on the front and rear sides of the support frame 100-1, with the tubing portion between the front and rear grooves essentially horizontal (meaning the top of the tubing in the suspended state is essentially horizontal). The multiple support frames 100-1 of the feeding device 100 are located below the first clamping mechanism 600 and the second clamping mechanism 700, from... Figure 12 , 13 As can be seen, the distance between the flow regulators 1-6 and the intravenous needle holders 1-5 in the infusion set products is not fixed. In the eight infusion set products shown in the figure, the distance between the flow regulators 1-6 and the intravenous needle holders 1-5 is different in each of the thesis. Furthermore, because the suspension position of the infusion set on the support frame 100-1 is not fixed, the vertical positions of the eight flow regulators 1-6 are disordered. However, all eight flow regulators 1-6 are located on the right side of the support frame 100-1, and the drip chamber 1-2 is located on the left side of the support frame 100-1 (e.g., ...). Figure 12 (As shown).

[0037] In step S2, the initial state of the first gripper 603 on the first clamping mechanism 600 is open, and the initial state of the second gripper 703 on the second clamping mechanism 700 is open. The controller issues a command, and the first Z-axis linear module 400 and the second Z-axis linear module 500 actuate to cause the first clamping mechanism 600 and the second clamping mechanism 700 to descend along the Z-axis. The open first gripper 603 and the open second gripper 703 descend from their initial positions to the top of the infusion set tubing, as shown below. Figure 14 As shown, at this time, the top of the tubing is located between clamping part 603-1 and clamping part 603-2, and between clamping part 703-1 and clamping part 703-2. Next, the controller issues a command to simultaneously close the first gripper 603 and the second gripper 703, so the tubing is located in the receiving space formed by recesses 603-1-1 and 603-2-1, and in the receiving space formed by recesses 703-1-1 and 703-2-1. Next, the first Z-axis linear module 400 and the second Z-axis linear module 500 move to raise the first clamping mechanism 600 and the second clamping mechanism 700 to their initial positions, and the first gripper 603 and the second gripper 703 move the infusion set upwards (the lifting parts 603-1-2 and 603-2-2 of the first gripper 603 lift the tubing upwards), and the infusion set is released from the support frame 100-1, completing the material handling process. At this time, the entire infusion set is still in a naturally hanging position.

[0038] Step S3: Straighten the infusion set so that it is in a straight line.

[0039] The controller commands the X-axis linear module 200 to move, causing the first Z-axis linear module 400 and the second Z-axis linear module 500 to move away from each other in the X-axis direction. (Reference) Figure 3 This means moving the first clamping mechanism 600 to the left and the second clamping mechanism 700 to the right; that is, moving the first gripper 603 to the left and the second gripper 703 to the right. The left endpoint P (the stop position) of the first gripper 603's leftward movement and the right endpoint Q (the stop position) of the second gripper 703's rightward movement, along with the distance L between the left endpoint P and the right endpoint Q, are determined based on the length of the infusion set. (Refer to...) Figure 15 and 16 When the infusion set is in a straight line and the small end of the flow regulator 1-6 is against the vein needle seat 1-5, the distance between the drip chamber 1-2 and the large end of the flow regulator 1-6 is the distance L.

[0040] There are three ways to straighten it: (a) The first method: The first clamping mechanism 600 and the second clamping mechanism 700 start moving simultaneously. The first clamping mechanism 600 moves to the left, and the second clamping mechanism 700 moves to the right. After a period of time, the first gripper 603 reaches the left endpoint P and stops, while the second gripper 703 reaches the right endpoint Q and stops. In other words, the first gripper 603 and the second gripper 703 reach their respective endpoints at the same time. Figure 15 and 16 As shown, the first gripper 603 abuts against the drip chamber 1-2, the second gripper 703 abuts against the large end of the flow regulator 1-6, and the small end of the flow regulator 1-6 abuts against the intravenous needle seat 1-5.

[0041] (ii) The second method: The first clamping mechanism 600 and the second clamping mechanism 700 start moving simultaneously. The first clamping mechanism 600 moves to the left, and the second clamping mechanism 700 moves to the right. The second clamp 703 stops at the right endpoint Q first, and the first clamp 603 stops at the left endpoint P afterward. At this time, the infusion set is straightened. The first clamp 603 abuts against the drip chamber 1-2, and the second clamp 703 abuts against the large end of the flow regulator 1-6, while the small end of the flow regulator 1-6 abuts against the intravenous needle seat 1-5.

[0042] (iii) The third method: The first clamping mechanism 600 and the second clamping mechanism 700 start moving simultaneously. The first clamping mechanism 600 moves to the left, and the second clamping mechanism 700 moves to the right. The first clamp 603 stops at the left endpoint P first, and the second clamp 703 stops at the right endpoint Q afterward. At this time, the infusion set is straightened. The first clamp 603 abuts against the drip chamber 1-2, and the second clamp 703 abuts against the large end of the flow regulator 1-6, while the small end of the flow regulator 1-6 abuts against the intravenous needle seat 1-5.

[0043] In this method, the settings can be further optimized, namely: the first clamping mechanism 600 and the second clamping mechanism 700 start moving simultaneously, the first clamping mechanism 600 moves to the left and the second clamping mechanism 700 moves to the right; next, the second clamping mechanism 700 moves to the right a certain distance and then stops (that is, the second gripper 703 moves to the right to position point S and stops moving), the first gripper 603 first reaches the left endpoint P and stops, then the second gripper 703 continues to move to the right (that is, after the first gripper 603 reaches the left endpoint P, the second gripper 703 continues to move to the right), and then the second gripper 703 reaches the right endpoint Q and stops.

[0044] Further optimization settings: The distance between position point S and the right endpoint Q is one-ninth of the distance L. The advantage of this setting is that when processing multiple infusion sets arranged side-by-side, or when adjacent infusion sets are close together, the tubing at the vein needle seats 1-5 of adjacent infusion sets will not interfere with or become tangled during the movement of the second gripper 703 from position point S to the right endpoint Q, ensuring operational quality and efficiency. Further optimization settings: The speed of the second gripper 703 during its movement from position point S to the right endpoint Q is V2, and the speed of the first gripper 603 during its movement from the starting point to the left endpoint P is V1, where V2 < V1.

[0045] Step S4: Position the vein needle hub 1-5 using the third clamping mechanism 800.

[0046] In step S401, the third clamping mechanism 800 clamps the small end of the flow regulator 1-6. Specifically, the third gripper 804 is initially in an open state. The third Z-axis linear module 900 lowers the third clamping mechanism 800, and then the translation module 802 moves the third gripper 804 forward. The third gripper 804 then moves to the position of the flow regulator 1-6, with the small end of the flow regulator 1-6 located between the first clamping part 804-1 and the second clamping part 804-2. Next, the third drive unit 803 closes the third gripper 804. Figure 17 As shown, the small end of the flow regulator 1-6 is located in the receiving space formed by the recess 804-1-1 and the recess 804-2-1. At this time, the small end of the flow regulator 1-6 can move in the receiving space and is not locked.

[0047] It should be noted that the third Z-axis linear module 900 and the translation module 802 can simultaneously move the third gripper 804 to the position of the flow regulator 1-6.

[0048] It should be noted that, regarding the action of the third clamping mechanism 800, the third gripper 804 can be aligned with the flow regulator 1-6 in the horizontal direction in advance, thus eliminating the need for the process of "the third Z-axis linear module 900 moving to lower the third clamping mechanism 800".

[0049] It should be noted that, regarding the action of the third clamping mechanism 800, the third gripper 804 can be aligned with the flow regulators 1-6 in the horizontal direction in advance, and the third gripper can wait in the appropriate position. This eliminates the need for "the third Z-axis linear module 900 to lower the third clamping mechanism 800" and "the translation module 802 to move the third gripper 804 forward".

[0050] In step S402, the second gripper 703 opens, and then the second Z-axis linear module 500 moves to raise the second clamping mechanism 700 a certain distance, that is, to raise the second gripper 703 a certain distance, so that the second gripper 703 moves away from the tubing of the infusion set. At this time, the rightward pushing force of the second gripper 703 disappears, and the end face of the intravenous needle seat 1-5 abuts against the end faces of the first clamping part 804-1 and the second clamping part 804-2, as shown. Figure 18 As shown.

[0051] Step S5: Allow the second gripper 703 to clamp the flow regulator 1-6.

[0052] The X-axis linear module 200 moves to displace the second gripper 703 a short distance to the right, positioning the second gripper 703 above the flow regulator 1-6. Then, the Z-axis linear module 500 moves to lower the second gripper 703 to the position of the flow regulator 1-6. The first gripping part 703-1 and the second gripping part 703-2 of the second gripper 703 are located on both sides of the flow regulator 1-6. Next, the second gripper 703 is closed, and the second gripper 703 clamps the flow regulator 1-6, which is then tightened and cannot move relative to the second gripper 703.

[0053] In step S6, the X-axis linear module 200 actuates, causing the second Z-axis linear module 500 to move to the left in the X-axis direction. This means the second clamping mechanism 700 moves to the left, specifically the second gripper 703. The second gripper 703 then moves the flow regulator 1-6 a certain distance to the left before stopping. This distance is the distance between the flow regulator 1-6 and the intravenous needle hub 1-5. Figure 20 As shown. The tubing at the vein needle hub 1-5 is located in the receiving space formed by the recess 804-1-1 of the first clamping part 804-1 and the recess 804-2-1 of the second clamping part 804-2 of the third clamp 804.

[0054] Next, the second gripper 703 is opened; then, the second Z-axis linear module 500 moves to raise the second gripper 703, moving it away from the flow regulator 1-6. This completes the adjustment of the flow regulator 1-6 position.

[0055] As can be seen, the position adjustment method for flow regulators 1-6 is to adjust them away from the intravenous needle hub 1-5, using the hub as a reference. During the movement of flow regulators 1-6 along the tubing, the larger end is in front and the smaller end is behind. It should be noted that the specific distance between flow regulators 1-6 and the intravenous needle hub 1-5 after adjustment is determined according to actual needs; flow regulators 1-6 can be placed closer to or farther from the intravenous needle hub 1-5.

[0056] Step S6: Release the infusion set product whose flow regulator position has been adjusted.

[0057] The specific process can be as follows: The Y-axis linear module 300 moves synchronously, causing the first clamping mechanism 600 and the third clamping mechanism 800 to move synchronously along the Y-axis. This means the first gripper 603 and the third gripper 804 move synchronously along the Y-axis, carrying the infusion set with the flow regulator already adjusted. The infusion set will not fall during this movement. When it reaches the desired position, such as above the conveyor belt or platform, the first Z-axis linear module 400 and the third Z-axis linear module 900 move synchronously, causing the first clamping mechanism 600 and the third clamping mechanism 800 to descend. This causes the first gripper 603 and the third gripper 804 to descend with the infusion set. Once the infusion set is placed on the conveyor belt or platform, the first clamping mechanism 600 and the third clamping mechanism 800 stop moving. Next, the first gripper 603 and the third gripper 804 open. Next, the first clamping mechanism 600 and the third clamping mechanism 800 are raised, and the first jaw 603 and the third jaw 804 are moved away from the infusion set.

[0058] Step S7: Return the first clamping mechanism 600, the second clamping mechanism 700 and the third clamping mechanism 800 to their initial positions, in preparation for processing the next set of infusion sets on the feeding device 100.

[0059] It should be noted that, regarding such Figure 12 The suspended infusion set shown typically has the rollers in flow regulators 1-6 positioned at the larger end (where the rollers do not compress the tubing) or slightly compressing the tubing. It is possible that the rollers are located in the middle or near the smaller end of the flow regulator. In this case, the rollers in flow regulators 1-6 compress the tubing. Even in this situation, the process of straightening the infusion set to a straight position in step S3 can proceed smoothly. (Refer to...) Figure 21 When the second gripper 703 moves to the right, it pushes the flow regulator 1-6 to the right. After the flow regulator 1-6 moves a short distance to the right along the tubing, the roller 1-8 will move to the larger end of the flow regulator 1-6 (at this time, the roller 1-8 will not squeeze the tubing), ensuring that the roller 1-8 is located at the larger end of the flow regulator 1-6 when it finally abuts against the intravenous needle seat 1-5. During step 6, when the second gripper 703 moves the flow regulator 1-6 to the left, it ensures that the flow regulator 1-6 moves smoothly and without resistance, guaranteeing that the position of the flow regulator 1-6 is properly adjusted.

[0060] Regarding the control system, a PLC controller can be used.

[0061] about Figure 12 The loading station shown can be moved horizontally by a translation device, so that the multiple support frames 100-1 of the loading device 100 are located below the first clamping mechanism 600 and the second clamping mechanism 700.
