[0044] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0045] See also Figures 1 to 8 The catheter shaping mechanism provided in this embodiment includes a transfer assembly 100, and the transfer assembly 100 includes a single-tube transfer member 110, and the transfer end point of the single-tube transfer member 110 is the tube removal position. It also includes an adjustment assembly 200, a picking member 300 and a first driving member 400, and the picking member 300 has a picking portion, and a limiting portion is provided on the picking portion. The adjustment assembly 200 includes a first transmission member 210, and the driving end of the first driving member 400 is transmission-connected to the first transmission member 210. There are two picking members 300, and the two picking members 300 are respectively arranged on both sides of the tube removal position and are arranged opposite to each other, and are transmission-connected to the first transmission member 210. The first transmission member 210 drives the two picking members 300 to approach or move away from each other along the extension direction of the first transmission member 210.

[0046] Specifically, when shaping the catheter, the single-tube transfer member 110 transfers the single catheter to the tube removal location, and the first driving member 400 drives the first transmission member, so that the first transmission member drives the picking member 300 to move. The two picking members 300 move to both sides of the tube removal location and approach each other until the picking parts of the two picking members 300 can be connected with the catheter on the single-tube transfer member 110, and slide with the catheter, so that both ends of the catheter are placed on the two picking members 300.

[0047] After the two ends of the conduit are stably placed on the two picking members 300, the two picking members 300 move away from each other. The two ends of the conduit have curved pipes. When the two picking members 300 move away from each other to the curved pipes, the limiting parts cooperate with the curved pipes so that the curved pipes are stuck in the limiting parts. The two picking members 300 continue to move away from each other, so that the conduit is subjected to tension. The conduit is straightened under the moving away action of the picking members 300, and the straightening process of the conduit is realized. The conduit can be directly transferred to the next process. The whole process is an automated operation without manual participation, and the processing speed is fast, thereby improving the assembly efficiency of the conduit and reducing the cost.

[0048] In this embodiment, the adjustment component 200 also includes a second transmission member 220 and a second driving member 230. The extension direction of the second transmission member 220 forms an angle with the extension direction of the first transmission member 210. The second transmission member 220 is arranged on the first transmission member 210, and the picking member 300 is transmission-connected to the second transmission member 220.

[0049] The extension direction of the second transmission member 220 is different from that of the first transmission member 210, so that the picking member 300 can move in two different directions, thereby facilitating the adjustment component 200 to move the catheter to other positions after shaping and adjustment.

[0050] Specifically, the first transmission member 210 in this embodiment extends in the horizontal direction, and the second transmission member 220 extends in the vertical direction. When the single-tube transfer member 110 moves the catheter to the tube-taking position, the two picking members 300 move in the vertical direction under the action of the second transmission member 220, so that the two picking members 300 and the single-tube transfer member 110 are located in the same horizontal plane and are respectively located on both sides of the single-tube transfer member 110. Subsequently, the first transmission member 210 drives the two picking members 300 to move closer to each other, so that both picking members 300 move toward the single-tube transfer member 110. When the two picking members 300 move to the single-tube moving member, the catheter on the single-tube moving member is engaged with the picking members 300 on both sides. After the catheter is engaged with the picking members 300, the single-tube transfer member 110 is reset to take the tube again.

[0051] In this embodiment, a connecting portion 221 is provided at one end of the second transmission member 220 . The connecting portion 221 is connected to the first transmission member 210 , and the second transmission member 220 moves along the extending direction of the first transmission member 210 .

[0052] Specifically, the second transmission member 220 in this embodiment is connected to the first transmission member 210 through the connecting part 221, so that the second transmission member 220 can move along the extension direction of the first transmission member 210, and the picking member 300 in this embodiment is arranged on the second transmission member 220, that is, the second transmission member 220 drives the picking member 300 to move in the horizontal direction under the transmission of the first transmission member 210.

[0053] As an implementable method, the two picking members 300 can be arranged on two guide rails extending in the vertical direction, and the two guide rails are connected to the first transmission member 210 so that the two guide rails can move along the extension direction of the first transmission member 210, thereby realizing the horizontal movement of the two picking members 300. In addition, the two picking members 300 are transmission-connected with the second transmission member 220, and move along the extension direction of the guide rails under the transmission of the second transmission member 220. Among them, the second transmission member 220 can be a slider moving in the vertical direction, and the second driving member 230 can be a motor connected to a screw rod. The slider moves along the length direction of the screw rod under the rotation of the screw rod, and the slider is connected to the two picking members 300 through connecting members such as guide rods and connecting pipes, so that the two picking members 300 follow the slider to move in the vertical direction, thereby realizing the vertical movement of the two picking members 300. In this way, the vertical and horizontal movements of the two picking members 300 are realized.

[0054] In this embodiment, the first transmission member 210 includes a conveyor belt, which is an annular structure, and the two straight segments of the conveyor belt are respectively a first straight segment 211 and a second straight segment 212, and the first straight segment 211 and the second straight segment 212 are arranged in parallel and spaced apart. Two second transmission members 220 are provided, one of which is connected to the first straight segment 211, and the other is connected to the second straight segment 212, and the two picking members 300 are respectively arranged on the two second transmission members 220.

[0055] The first straight segment 211 and the second straight segment 212 of the conveyor belt move in opposite directions. The two second transmission members 220 are respectively arranged on the first straight segment 211 and the second straight segment 212. The first driving member 400 in this embodiment is a driving motor. The output end of the driving motor is a driving shaft. The outer wall of the driving shaft is provided with external teeth. The inner wall of the conveyor belt is provided with internal teeth meshing with the external teeth. Under the drive of the driving motor, the conveyor belt rotates together with the driving shaft. The first straight segment 211 and the second straight segment 212 move in the horizontal direction. The first straight segment 211 and the second straight segment 212 drive the two second transmission members 220 to move in opposite directions. The picking members 300 on the two second transmission members 220 move in opposite directions following the two second transmission members 220.

[0056] As an implementable method, the first transmission member 210 may use a rack. In this structure, the first straight segment 211 and the second straight segment 212 are arranged with the same rack interval, and the first straight segment 211 and the second straight segment 212 are arranged in opposite directions. The first driving member 400 uses a rotary motor and is arranged at the midpoint of the first straight segment 211 and the second straight segment 212. A gear meshing with the rack is sleeved on the rotating shaft of the rotary motor. The first straight segment 211 and the second straight segment 212 are meshed with the gear from the upper and lower sides of the gear respectively. When the gear rotates, the first straight segment 211 and the second straight segment 212 move in opposite directions. The two second transmission members 220 follow the first straight segment 211 and the second straight segment 212 to move respectively, so that the picking members 300 on the two second transmission members 220 can follow the two second transmission members 220 to move in opposite directions.

[0057] Furthermore, the second transmission member 220 in this embodiment is a cylinder, the moving direction of the moving end of the cylinder is the vertical direction, and the picking member 300 is installed on the moving end of the cylinder. Each cylinder is provided with a seat extending in the horizontal direction, and the two seats are respectively connected to the first straight segment 211 and the second straight segment 212, so that the two cylinders are connected to the first transmission member 210 through the seat, so that the cylinders can move in the horizontal direction under the drive of the first transmission member 210. Specifically, the specific process in this embodiment is that the single-tube transfer member 110 transfers the conduit to the tube-taking location, the picking member 300 moves to the top of the conduit under the drive of the cylinder, and the two picking members 300 follow the cylinder to move toward each other under the drive of the conveyor belt. After the positions of the two picking members 300 are close to the single-tube transfer member 110, the cylinder operates again so that the two picking members 300 can move down to take the tube. After both picking members 300 are connected to the catheter, the single-tube transfer member 110 moves away horizontally to pick up the tube again, and the two picking members 300 move away from each other to straighten the catheter to achieve shaping and adjustment of the catheter.

[0058] In this embodiment, the picking portion includes a picking clamp 310 , and the limiting portion includes a clamping slot 320 . The clamping slot 320 is disposed between two clamps of the picking clamp 310 and is adapted to the outer wall of the catheter.

[0059] The object-removing clamp 310 is a clamp body, and a clamping slot 320 is provided between the two clamp bodies. Before the picking member 300 takes the tube, the two clamp bodies are in an open state. When taking the tube, the two clamp bodies are on both sides of the tube and perform a closing action. The position of the clamping slot 320 is opposite to the position of the tube, so that after the two clamp bodies are closed, the tube is located in the clamping slot 320. In addition, the inner wall of the clamping slot 320 in this embodiment is slidably matched with the outer wall of the tube, so that when the two object-removing clamps 310 move away from each other, the inner wall of the clamping slot 320 slides relative to the outer wall of the tube.

[0060] Among them, both ends of the catheter are provided with a curved pipe structure or an adjusting valve. Therefore, when the two picking clamps 310 move away from each other until they abut against the curved pipe structure or the adjusting valve, the curved pipe structure and the adjusting valve will be stuck outside the slot 320 due to their large size. When the two picking clamps 310 continue to move away from each other, the catheter will be straightened by the curved pipe structure or the adjusting valve at both ends.

[0061] As an implementable method, the picking part can be a right-angle structure or a hook structure. Taking the hook structure as an example, when the picking part 300 takes the tube, the hook structure holds up the catheter on both sides of the short tube, and under this structure, the limit part is replaced by a guide plate, which extends outward at the opening of the hook body so that the catheter can smoothly fall into the hook body. The opening area in the hook body is smaller than the cross-sectional area of ​​the curved tube structure and the adjustment valve of the catheter. When the two picking clamps 310 move away from each other until they abut against the curved tube structure or the adjustment valve, the curved tube structure and the adjustment valve will be stuck outside the card slot 320 due to their oversized size. When the two picking clamps 310 continue to move away from each other, the catheter will be straightened by the curved tube structure or the adjustment valve at both ends.

[0062] It should be noted that there are multiple picking clamps 310 in this embodiment, and the multiple picking clamps 310 are symmetrically arranged on the two picking members 300. Correspondingly, there are also multiple single-tube transfer members 110. When the two picking members 300 pick up the tube, every two picking clamps 310 can clamp a single tube on the single-tube transfer member 110 to straighten it, and the two picking members 300 can clamp multiple tubes on multiple single-tube transfer members 110 at one time.

[0063] In this embodiment, the catheter shaping mechanism also includes a transfer assembly 500, which includes a guide member 510, a third driving member and a tube picking member 520. The tube picking member 520 is arranged on the guide member 510, and the tube picking member 520 is connected to the third driving member. There is a picking position on the moving path of the tube picking member 520. When the tube picking member 520 is at the picking position, the tube picking member 520 is located between the two picking members 300.

[0064] Specifically, the guide member 510 is a guide frame, and a guide groove is provided on the guide frame, and the extension direction of the guide groove is the same as the direction of the connection line between the two picking members 300. The end of the tube-taking member 520 is inserted into the guide groove and slidably cooperates with the guide groove, so that the tube-taking member 520 can move along the guide groove, thereby adjusting the horizontal position of the tube-taking member 520.

[0065] On the other hand, the third driving member in this embodiment is a driving cylinder, which is arranged above the guide frame. The moving direction of the moving end of the driving cylinder is a vertical direction. The guide frame is connected to the moving end of the driving cylinder, thereby realizing the vertical movement of the guide frame and the pipe taking member 520, facilitating the vertical movement of the pipe taking member 520 to take out the pipe or remove the catheter.

[0066] In this embodiment, there are two tube taking components 520. When located at the object taking position, the two tube taking components 520 are located at both sides of the tube taking position.

[0067] The two tube-taking members 520 can be connected and fixed to two positions of the catheter to achieve a stable connection to the catheter. The tube-taking member 520 in this embodiment is a clamping body. When taking the tube, the two tube-taking members 520 clamp the catheter at both sides of the tube-taking location. Specifically, the two tube-taking members 520 are respectively located at both sides of the tube-taking location and are both located between the tube-taking location and the object-taking clamp 310. The positions of the two tube-taking members 520 are both close to the end of the catheter, which can prevent the catheter from shrinking after taking the tube.

[0068] Furthermore, the positions of the two tube-taking components 520 in this embodiment can be adjusted by moving on the guide groove. The positions of the two tube-taking components 520 can be adjusted according to the lengths and specifications of different catheters. The adjustment is easy and the adaptability is strong.

[0069] It should be noted that the structure of the tube-taking member 520 in this embodiment is the same as that of the picking member 300, both of which are structures of multiple picking clamps 310. Furthermore, in this embodiment, multiple picking clamps 310 on each picking member 300 or tube-taking member 520 are arranged adjacent to each other, and each picking clamp 310 includes two clamp bodies, and the two clamp bodies are respectively a fixed plate and a movable plate. Among them, the fixed plate is fixed and stationary, and a cylinder is provided at one end of the picking clamp 310. Each movable plate is pushed by the cylinder to move closer to or away from the fixed plate, thereby realizing the opening and closing of the picking clamp 310. In addition, the slot 320 is a combined slot, and a through slot penetrating the clamp body is relatively provided on the fixed plate and the movable plate. When the fixed plate and the movable plate are closed, the two through slots merge into a combined through slot penetrating the clamp body.

[0070] In this embodiment, the transfer assembly 500 further includes a third transmission member 530 and a fourth driving member. The extension direction of the third transmission member 530 forms an angle with the extension direction of the guide member 510 , and the guide member 510 is transmission-connected to the third transmission member 530 .

[0071] Specifically, the fourth driving member in this embodiment is a driving motor, and the third transmission member 530 is a belt transmission member, and the driving motor is connected to the guide frame through the belt transmission member. Specifically, the driving cylinder in this embodiment is installed on the connecting plate, and a rotating wheel is provided on the top of the connecting plate, and the rotating wheel is connected with the belt transmission member. The belt transmission member rotates, contracts or extends under the drive of the driving motor, and the rotating wheel follows the belt transmission member to move forward or backward, so that the connecting plate, the driving cylinder and the guide frame can carry the pipe taking member 520 to move along the extension direction of the belt transmission member. The belt transmission member in this embodiment extends in the horizontal direction and is perpendicular to the extension direction of the guide groove, so as to realize the horizontal movement of the guide frame and the pipe taking member 520, so that the pipe taking member 520 can move the catheter in the horizontal direction after taking the pipe.

[0072] Also, see Figure 2 In this embodiment, guide rails are provided on both sides of the belt transmission member, and the guide rails extend in the horizontal direction and are perpendicular to the extension direction of the guide groove. A movable plate 531 is provided on the belt transmission member, and the movable plate 531 moves with the belt transmission member and the two ends of the movable plate 531 slide in cooperation with the guide rails, so that the moving direction of the belt transmission member can be kept the same as the extension direction of the two guide rails.

[0073] In this embodiment, the catheter shaping mechanism further includes a tube pressing member 600, which is disposed between the two tube taking members 520, and the tube pressing member 600 is located between the tube taking member 520 and the tube taking location.

[0074] The tube pressing member 600 can press down the middle part of the tube when the picking member 300 straightens the tube and the tube taking member 520 takes the tube, so as to assist the picking member 300 in straightening the tube or ensure that the tube remains straight when the tube taking member 520 takes the tube.

[0075] Specifically, the tube pressing member 600 in this embodiment is installed on the guide frame. Under this structure, the relative positions of the tube pressing member 600 and the tube taking member 520 remain fixed, so that the tube taking member 520 can keep the catheter in a straight state when moving the catheter after taking the tube.

[0076] The bottom of the tube pressing member 600 in this embodiment is provided with a plurality of dividing grooves, the number of which is the same as the number of the object taking clamp 310 and the positions are opposite, so that the position of the catheter can be fixed while pressing down.

[0077] In this embodiment, the shaping mechanism also includes a moving component, the moving end of the moving component is connected to the single-tube transfer component 110; the single-tube transfer component 110 has a negative pressure material intake port 111, the single-tube transfer component 110 is connected to the negative pressure generating device and the negative pressure material intake port 111 faces downward.

[0078] The single-tube transfer member 110 is displaced from the catheter placement position to the tube removal position by a displacement assembly. Specifically, the moving assembly can adopt a variety of transmission structures, such as a transmission structure of a motor and a screw rod, a cylinder transmission structure, or a transmission structure of a motor and a conveyor belt. A transmission method in which the above-mentioned multiple transmission structures are combined can also be adopted to realize the movement of the single-tube transfer member 110.

[0079] Moreover, the catheter placement location in this embodiment is located below the tube taking location, and multiple single-tube transfer components 110 are arranged on the same frame, and the frame is moved vertically by a cylinder, thereby realizing the vertical movement of the single-tube transfer component 110. The single-tube transfer component 110 can move down to the catheter placement location to take the tube, and carry the catheter upward to deliver the catheter to the tube taking location.

[0080] The single-tube transfer member 110 in this embodiment is a negative pressure material taking member, and a negative pressure generator is connected to the negative pressure material taking port 111. When taking the tube, the negative pressure generator operates to generate negative pressure at the negative pressure material taking port 111, and the catheter is adsorbed on the negative pressure material taking port 111 from above the tube taking place, and the catheter is moved upward and carried to the tube taking place. After the picking member 300 clamps the catheter, the negative pressure generator stops running, the negative pressure material taking port 111 loses negative pressure, and the catheter falls off.

[0081] The catheter feeding device provided in this embodiment includes a material distribution mechanism 700, which includes a material discharge portion and a catheter shaping mechanism. The initial point of the single-tube transfer member 110 of the catheter shaping mechanism is located at the material discharge portion.

[0082] Specifically, the material dividing mechanism 700 in this embodiment can disperse a large number of stacked catheters and transfer them to the discharge section so that the catheters can be in a dispersed state. The discharge section is where the above-mentioned catheters are placed. The catheters are dispersedly placed in the discharge section, which is very convenient for the single-tube transfer part 110 to move to the discharge section to take the tubes.

[0083] In this embodiment, the material dividing mechanism 700 includes a feeding assembly 710 and a dividing assembly 720. The feeding assembly 710 is used to move the conduit to the discharge portion. The dividing assembly 720 is disposed in the discharge portion and is used to vibrate to disperse the conduit.

[0084] Specifically, the medical catheters are stacked on the feeding assembly 710, and the feeding assembly 710 pushes the stacked medical catheters toward the distributing assembly 720. After the stacked medical catheters move to the distributing assembly 720, the components in the distributing assembly 720 reciprocate up and down or left and right, so that the catheters are vibrated and dispersed. Specifically, in this embodiment, the distributing assembly 720 includes a distributing member, which reciprocates in the vertical direction to push the stacked medical catheters. After being pushed, the stacked medical catheters gradually disperse, so that a large number of stacked medical catheters are spread out and dispersed on the discharge part, and the single-tube transfer member 110 can take out the medical catheters from above. The distributing assembly 720 can disperse a large number of stacked medical catheters to avoid a large number of catheters crossing and stacking, which may cause the medical catheters to be damaged due to excessive tension and pressure when they are taken out.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
