[0089] The assembly device also includes three sets of in-place detection mechanisms, namely, the flat joint and first conduit in-place detection mechanism 91, the K-joint and first conduit in-place detection mechanism 92, and the K-joint and second conduit in-place detection mechanism 93. The flat joint and first conduit in-place detection mechanism 91 is located between the flat joint feeding and assembly device 3 and the K-joint feeding and assembly device 4, the K-joint and first conduit in-place detection mechanism 92 is located between the K-joint feeding and assembly device 4 and the second conduit feeding device 7, and the K-joint and second conduit in-place detection mechanism 93 is located between the K-joint and second conduit assembly device 5 and the product feeding device 6. Meanwhile, the assembly device is also provided with a first conduit two-end dotting mechanism 94 and a second conduit one-end dotting mechanism 95.

[0090] Since the joint is opaque when assembled into the conduit, a dotting mechanism is arranged before the conduit is assembled to spray glue and form fluorescent dots at a fixed position on the surface of the conduit. When detecting whether the joint is assembled in place, the fluorescent dots are actually detected to determine whether the joint is assembled in place. When the assembled product is moved by the material moving assembly, the vision takes a photo at the corresponding position for detection. The ultraviolet light source irradiates the fluorescent dots on the conduit, and the camera judges whether the conduit is assembled in place by taking the distance from the center of the fluorescent dots to the edge of the joint. Through the cooperation of the dotting mechanism and the detection mechanism, the assembly of the conduit and the joint is automatically detected, which ensures that defective products can be effectively detected, guarantees the qualified rate of finished products, and the overall equipment has high automation degree.

[0091] As shown in Figure 2 , it is a structural schematic diagram of the second assembly body C2, including the first conduit A1, the K-joint A3, and the flat joint A4. The corresponding first assembly body C1, which is not shown, is assembled by the first conduit A1 + the flat joint A4, and the third assembly body C3 is connected with the second conduit A2 to form the second assembly body C2 (the first conduit A1 + the flat joint A4 + the K-joint A3).

[0092] As shown in Figure 3As shown, the K joint A3 includes a joint part A31, a straight pipe interface A32, and an inclined pipe interface A33, wherein the joint part A31 is coaxially communicated with the straight pipe interface A32, and the inclined pipe interface A33 is connected in the middle of the straight pipe interface A32 in a direction towards the joint part A31, and the two have a certain included angle (45 degrees), in this station, the inclined pipe interface A33 and the joint part A31 are both towards the second conduit jig B2. The outer diameter of the joint part A31 is larger than the outer diameter of the straight pipe interface A32, and the inclined pipe interface A33 is tangent to the joint part A31 or only the pipe wall is connected. The joint part A31 can be equipped with a nut. Wherein, the straight pipe interface A32 is assembled with the first conduit A1, and the inclined pipe interface A33 is assembled with the second conduit A2.

[0093] As shown in the figure, Figures 4-9 The conduit conveying line in the embodiment includes a first conduit conveying line 101 for conveying the first conduit A1, and a second conduit conveying line 102 for conveying the second conduit A2. The first conduit A1 is a short conduit, which is 20 cm long. The second conduit A2 is a long conduit, which is 140 cm long.

[0094] The first conduit conveying line 101 and the second conduit conveying line 102 are arranged side by side in front and back. The first conduit conveying line 101 is composed of one unit conveying line 10, and the second conduit conveying line 102 is composed of two unit conveying lines 10. The first conduit conveying line 101 carries the first conduit jig B1, and the second conduit conveying line 102 carries two groups of second conduit jigs B2, which are carried on the two unit conveying lines 10 respectively. The two groups of second conduit jigs B2 clamp the second conduit A2 together from the front and back ends respectively and convey them to the right. The first conduit and the second conduit are assembled with the assembly at the end of the conveying line and are taken down. The idle conduit jigs are recycled from each unit conveying line to the head of each unit conveying line for reloading, forming a conveying cycle.

[0095] As shown in the figure, Figure 5 The two ends of the unit conveying line 10 are marked as conveying starting point 11 and conveying ending point 12 respectively.

[0096] The unit conveying line 10 includes a rack 100 and two conveying tracks 13 fixed on the rack 100, which are an upper conveying track 131 and a lower conveying track 132. The conveying track 13 is composed of a track pad 133 and a jig track 134. The track pad 133 is installed on the rack 100, and the jig track 134 is located on the track pad 133, Figure 5 As shown in the figure, the unit conveying line 10 in the second conduit conveying line 102 is taken as an example. The jig track 134 is arranged with the second conduit jig B2, and the second conduit jig B2 slides along the jig track 134. The conveying track 13 is provided with a jig pushing mechanism 14 at both ends.

[0097] The second catheter jig B2 is conveyed by the conveying starting point 11 to the conveying ending point 12 on the upper conveying track 131, and is conveyed by the conveying ending point 12 to the conveying starting point 11 on the lower conveying track 132, and the second catheter jig B2 is transferred between the upper conveying track 131 and the lower conveying track 132 by the pushing jig mechanism 14 and is pushed, so as to realize feeding and recycling effect of the second catheter jig B2.

[0098] Specifically, as shown in the figure, Figures 6-8 The pushing jig mechanism 14 includes a jig lifting assembly 15, a jig flat pushing assembly 16 and a jig transition assembly 17. The jig lifting assembly 15 controls the lifting of the jig flat pushing assembly 16 and the jig transition assembly 17. The jig transition assembly 17 can be connected with the upper conveying track 131 or the lower conveying track 132 and receive the catheter jig B2. The jig flat pushing assembly 16 pushes the catheter jig B2 on the jig transition assembly 17 into the lower conveying track 132 or the upper conveying track 131.

[0099] The jig lifting assembly 15 includes a lifting bottom fixed plate 151, a jig lifting driving source 152 and a lifting bottom plate 153. The lifting bottom plate 153 is controlled by the lifting driving source 152 to move up and down. The lifting bottom fixed plate 151 is fixedly connected with the rack and is a fixed structure. The fixed end 1521 of the lifting driving source is connected with the lifting bottom fixed plate 151 through a cylinder pad block, and the movable end 1522 of the lifting driving source is connected with the lifting bottom plate 153 through the lifting bottom fixed plate 151. The lifting side plates 154 are fixed on both sides of the lifting bottom plate 153 and move up and down with the lifting bottom plate 153. The lifting back plate 155 is fixedly connected with the lifting bottom fixed plate 151 and located outside the lifting side plates 154. The lifting plate slide rail 156 is arranged outside the lifting side plates 154, and the lifting back plate 155 is fixedly provided with a sliding block on the side facing the lifting side plates 154. The lifting side plates 154 can slide up and down along the lifting back plate 155.

[0100] In the embodiment, the pushing jig mechanism 14 is further provided with a lifting sensing part 141, including the lifting sensing blocks 1411 installed on the upper and lower side ends of the lifting side plates 154 and the lifting sensor 1412 installed on the same side end of the lifting back plate 155. The lifting sensing part 141 can further limit the lifting stroke of the lifting bottom plate 153 and improve the lifting accuracy.

[0101] The lifting base 153 houses a jig pusher assembly 16 and a jig transition assembly 17, arranged side by side. The jig transition assembly 17 rises and falls with the lifting base 153, transferring and pushing the second conduit jig B2. The jig transition assembly 17 connects to the conveyor track 13 to receive the second conduit jig B2 arriving at the starting point 11 of the lower conveyor track 132 or the end point 12 of the upper conveyor track 131. The jig pusher assembly 16 pushes the second conduit jig B2 forward on the jig transition assembly 17, allowing it to move forward on the conveyor track 13.

[0102] The fixture transition assembly 17 includes a slide rail pad 171 and a transition guide rail 172. The slide rail pad 171 is fixed on the lifting base 153. The transition guide rail 172 is located on the slide rail pad 171 and can carry the second catheter fixture B2.

[0103] The jig push assembly 16 includes a jig push drive source 161 and a push plate connecting block 162 installed on the slide of the jig push drive source 161. The jig push drive source 161 drives the push plate connecting block 162 to move forward and backward along the direction of the transition guide rail 172. The front end of the push plate connecting block 162 is connected to a jig push block 163. The jig push block 163 is parallel to the direction of the transition guide rail 172 and can contact the second catheter jig B2 on the transition guide rail 172.

[0104] In this embodiment, the jig pushing mechanism 14 is further equipped with a horizontal push sensing component 142, comprising a horizontal push sensing plate 1421 mounted on the push plate connecting block 162, a horizontal push sensor 1422 mounted on the slide rail pad 171, and a zero return assembly 1423 mounted on the lifting base 153, with the zero return assembly 1423 located behind the horizontal push sensor 1422. The horizontal push sensing plate 1421 moves back and forth with the push plate connecting block 162 and slides past the zero return assembly 1423 and horizontal push sensor 1422, further limiting the horizontal push travel of the push plate connecting block 162 and the jig pushing block 163, accurately pushing the second catheter jig B2 out of the transition guide rail 172 and ensuring that the second catheter jig B2 advances a consistent distance on the conveyor track 13.

[0105] like Figure 9 As shown, the unit conveyor line 10 is further provided with a jig positioning assembly 18, which is placed at both ends of the conveying track 13, and is placed at both ends of the upper and lower conveying tracks 131 and 132. At the same time, a jig positioning assembly 18 is also placed on the end of the jig pushing mechanism 14 facing the conveying track 13. Each jig positioning assembly 18 is used to cooperate to position the second catheter jig B2 in place and limit its movement. The moving distance of the second catheter jig B2 is more accurate, and the front and rear squeezing of the catheter jig is avoided. The lifting space of the catheter jig in the jig pushing mechanism 14 is guaranteed to avoid jamming, thereby improving the success rate of the transfer of the catheter jig on the upper and lower conveying tracks 131 and 132.

[0106] The jig positioning assembly 18 comprises a jig positioning cylinder 181, the fixed end of the jig positioning cylinder 181 is fixedly connected with the slide rail pad 171 or the track pad 123, the movable end of the jig positioning cylinder 181 is upward and connected with a positioning pin 182, and the jig positioning cylinder 181 controls the lifting of the positioning pin 182. The second catheter jig B2 is correspondingly provided with a jig positioning hole B21, and the positioning pin 182 is inserted and pulled out in the jig positioning hole B21, so that the positioning effect of the second catheter jig B2 is achieved.

[0107] The conveying process of the unit conveying line 10 in the embodiment is as follows:

[0108] 1. The initial state of the push jig mechanism 14 at the conveying starting point 11 is that the jig pushing assembly 16 and the jig transition assembly 17 are in the raised state, the second catheter jig B2 is stored on the transition rail 172 of the jig transition assembly 17 and is connected with the conveying starting point 11 of the upper conveying rail 131, and the push jig block 163 is in contact with the end of the second catheter jig B2 on the transition rail 172. The initial state of the push jig mechanism 14 at the conveying ending point 12 is that the jig pushing assembly 16 and the jig transition assembly 17 are in the raised state, the transition rail 172 of the jig transition assembly 17 is empty and is connected with the conveying ending point 12 of the upper conveying rail 131. At the same time, the upper conveying rail 131 and the lower conveying rail 132 are both paved with the second catheter jig B2.

[0109] 2. The jig pushing assembly 16 on the push jig mechanism 14 at the conveying starting point 11 works, the jig pushing drive source 161 drives the push jig block 163 to push the second catheter jig B2 on the transition rail 172 to move towards the conveying ending point 12, the second catheter jig B2 on the upper conveying rail 131 is progressively moved forward, the second catheter jig B2 at the conveying ending point 12 of the upper conveying rail 131 enters the transition rail 172 of the push jig mechanism 14 at the conveying ending point 12, and the push jig block 163 is pushed to the position and then returns to the zero point controlled by the jig pushing drive source 161. At this time, the transition rail 172 of the push jig mechanism 14 at the conveying starting point 11 is in the empty state, and the second catheter jig B2 is placed on the transition rail 172 of the push jig mechanism 14 at the conveying ending point 12.

[0110] 3. The jig lifting assemblies 15 of the push jig mechanisms 14 at the conveying starting point 11 and the conveying ending point 12 work at the same time, the jig lifting drive source 152 controls the lifting bottom plate 153 to descend, drives the corresponding jig pushing assembly 16 and the jig transition assembly 17 to descend at the same time, and the transition rail 172 is connected with the lower conveying rail 132.

[0111] 4. The jig push assembly 16 on the jig pushing mechanism 14 at the conveying terminal 12 works, and the jig push driving source 161 drives the jig pushing block 163 to push the second catheter jig B2 on the transition guide rail 172 toward the conveying starting point 11. The second catheter jig B2 on the lower conveying track 132 moves forward progressively, and the second catheter jig B2 at the conveying starting point 11 of the lower conveying track 132 enters the transition guide rail 172 of the jig pushing mechanism 14 at the conveying starting point 11. After the jig pushing block 163 is pushed into place, it is controlled by the jig push driving source 161 to return to zero. At this time, the transition guide rail 172 on the jig pushing mechanism 14 at the conveying terminal 12 is in an empty state, and the second catheter jig B2 is placed on the transition guide rail 172 of the jig pushing mechanism 14 at the conveying starting point 11.

[0112] 5. The jig pushing mechanism 14 located at the conveying starting point 11 and the conveying end point 12, and its jig lifting assembly 15 work simultaneously, and the jig lifting drive source 152 controls the lifting base plate 153 to rise, driving the corresponding jig push assembly 16 and jig transition assembly 17 to rise simultaneously until the transition guide rail 172 is connected to the upper conveying track 131.

[0113] 6. Repeat steps 2-5 to realize the cyclic conveying of the second catheter fixture B2, thereby completing the conveying purpose of the second catheter.

[0114] The unit conveyor line 10 in this embodiment can be used to transport and assemble catheters of different lengths. It adopts an upper and lower stacking and pushing method for transportation, which makes more rational use of the upper and lower spaces, reduces the flat surface occupied, and is more compact in overall structure, effectively reducing production costs. Multiple unit conveyor lines can be combined to meet more and more complex catheter transportation and assembly needs, making the equipment products more competitive. At the same time, the jig pushing mechanism 14 is used to transfer and push the catheter jig between the upper conveyor track 131 and the lower conveyor track 132. It is particularly suitable for the transfer of wide multi-station catheter jigs (if a belt-type upper and lower conveyor is used, the catheter jig is not easy to turn, and the empty catheter jig will be transported partially downward, posing a risk of falling off). The catheter jig always moves progressively upward on the conveyor track, making the placement of the catheter jig more secure and the accuracy of catheter transportation higher.

[0115] like Figures 10-16 As shown, the second tube feeding device 7 provided in this embodiment includes a tube discharging mechanism 71 , a tube cutting mechanism 72 and a tube pulling and feeding mechanism 73 .

[0116] The conduit discharge mechanism 71 includes a conduit material rack 710 and a plurality of discharge components 711. Two sets of discharge components 711 are set on one side of the conduit material rack 710, one for backup and one for use, to ensure that the system can automatically switch to a new material tray after a roll of material is used up.

[0117] The feeding assembly 711 comprises a hopper 712, a roller sleeve assembly 713, a length counting assembly 714, a transition pulley 715, a feeding pulley assembly 716, a top pulley 717 and a limiting roller assembly 718. The catheter passes through the hopper 712, the roller sleeve assembly 713, the length counting assembly 714, the feeding pulley assembly 716, the top pulley 717 and the limiting roller assembly 718 in sequence to the cutting mechanism 72, and the transition pulley 715 is used to transition the guide when a turn is needed. The number of the transition pulleys 715 depends on the actual arrangement requirement, and the number of the transition pulleys 715 on the two feeding assemblies 711 does not need to be consistent.

[0118] The roller sleeve assembly 713 comprises a connecting frame 7131 fixed on the catheter rack 710 and a limiting roller sleeve 7132 rotatably arranged on the connecting frame 7131. The roller sleeve assembly 713 provides an additional pipe tightening effect between the hopper 712 and the length counting assembly 714.

[0119] The length counting assembly 714 comprises, from back to front, the limiting roller assembly 718, a tension sensor 7141 and a driven feeding assembly 7142, wherein the driven feeding assembly 7142 comprises a driven feeding wheel 7143 and a roller pressing assembly 7144. In the device, the tension sensor 7141 is arranged to monitor the catheter tension in real time when the catheter passes through the driven feeding assembly 7142, so as to ensure the uniform and stable transmission of the catheter, and the driven feeding assembly 7142 is used to monitor the output length of the catheter, so as to further ensure the fixed-length feeding and conveying of the catheter.

[0120] The transition pulley 715 is used to assist in conveying the catheter and ensure that the catheter is in a tensioned state during the feeding process.

[0121] The feeding pulley assembly 716 comprises fixed blocks 7161 fixed on the catheter rack 710, a slide rod 7162, a guide block 7163, a lifting pulley 7164 and a lifting pulley sensing assembly 7165. The slide rod 7162 is arranged between the upper and lower fixed blocks 7161, the guide block 7163 is arranged on the slide rod 7162 and can slide up and down along the slide rod 7162, the lifting pulley 7164 is rotatably connected to the guide block 7163, and the lifting pulley sensing assembly 7165 is arranged on the upper part of the slide rod 7162 to limit the maximum distance of the upward movement of the lifting pulley 7164.

[0122] One top pulley 717 is arranged on each of the left and right sides above the feeding pulley assembly 716, and cooperates with the lifting pulley 7164 to lift the lifting pulley 7164 from a high position.

[0123] In this embodiment, two sets of discharge assemblies 711 are set on a single side of the tube rack 710, wherein the two sets of discharge pulley assemblies 716 on the same side are staggered left and right, and the corresponding transition pulleys 715 are staggered up and down, so that the tube discharge routes of the two sets of discharge assemblies 711 are staggered and circuitous but do not cross each other, making full use of the rack space, with an ingenious design, while meeting the tube loading needs of multiple stations and improving the tube transportation efficiency. Specifically, for the convenience of description, in Figure 12 They are marked as discharge assembly 711-1 and discharge assembly 711-2 respectively, and the corresponding discharge assembly 711-1 is divided into a transition pulley 715-1, a discharge pulley assembly 716-1, and a top pulley 717-1; the discharge assembly 711-2 is divided into a transition pulley 715-2, a discharge pulley assembly 716-2, and a top pulley 717-2. The unloading pulley assembly 716-1 and the unloading pulley assembly 716-2 are arranged in a staggered manner in parallel on the left and right, and have a certain height difference. The corresponding top pulley 717-1 is also higher than the top pulley 717-2. The transition pulley 715-1 that cooperates with the unloading pulley assembly 716-1 is arranged above the top pulley 717-2 and connected flush with the top pulley 717-1. The transition pulley 715-2 that cooperates with the unloading pulley assembly 716-2 is arranged under the unloading pulley assembly 716-1. In this way, the unloading routes of the two groups of unloading assemblies 711 are staggered, the staggered arrangement effectively utilizes the space, and at the same time ensures that the conduit is in a tensioned state during the unloading process.

[0124] like Figure 13 As shown, the tube cutting mechanism 72 includes a tube guide assembly 721, a tube cutting assembly 722, and a tube cutting transverse movement drive 723 for driving the tube cutting assembly 722 to move transversely. The tube cutting assembly 722 is placed as a whole on the slide of the tube cutting transverse movement drive 723. After one set of tubes is cut and loaded, the tube cutting assembly 722 moves transversely to another set of tube drawing and loading stations, where it continues to draw and cut tubes without time intervals. The movable design of the tube cutting assembly 722 allows the subsequent tube drawing and loading mechanism 73 to grab the tubes at an offset position, without having to wait for the return stroke to retrieve the material. Instead, it can directly pull two tubes after pulling them. This is especially true for long tubes, which take a long time to pull. This design saves loading time for long tubes and improves the assembly efficiency of the overall equipment.

[0125] like Figures 14-16As shown, the pull tube feeding mechanism 73 includes two sets of pull tube feeding assemblies 731 arranged oppositely, the pull tube feeding assembly 731 includes a first feeding tube clamping assembly 732, a second feeding tube clamping assembly 733 and a pull tube assembly 734 from back to front, and a guide tube translation feeding drive 735 driving the first feeding tube clamping assembly 732, the second feeding tube clamping assembly 733 and the pull tube assembly 734 to move back and forth, wherein the second feeding tube clamping assembly 733 and the pull tube assembly 734 are fixedly connected through a pull tube connecting plate 736 to make the second feeding tube clamping assembly 733 and the pull tube assembly 734 move back and forth synchronously. The first feeding tube clamping assembly 732 includes a first feeding tube lifting drive source 7321 and two sets of first tube clamping fingers 7322, the second feeding tube clamping assembly 733 includes a second feeding tube lifting drive source 7331 and two sets of second tube clamping fingers 7332, the pull tube assembly 734 includes a pull tube translation drive source 7341 and two sets of pull tube clamping fingers 7342, and the pull tube clamping fingers 7342 are directed towards the pipe cutting mechanism 72 and are leveled with the pipe outlet height of the pipe cutting assembly 722.

[0126] When the pipe pulling feeding mechanism 73 works with the pipe cutting mechanism 72, the first feeding pipe clamping assembly 732, the second feeding pipe clamping assembly 733 and the pipe pulling assembly 734 on a set of pipe pulling feeding assemblies 731 are in the original state, that is, the first pipe clamping fingers 7322 and the second pipe clamping fingers 7332 are located above the pipe cutting mechanism 72, the pipe pulling fingers 7342 clamp the front end of the guide pipe at the discharge port of the pipe cutting assembly 722, the guide pipe translation feeding drive 735 drives the second feeding pipe clamping assembly 733 and the pipe pulling assembly 734 to move forward and pull out the guide pipe to a certain length, the first pipe clamping fingers 7322 and the second pipe clamping fingers 7332 simultaneously descend to clamp the second guide pipe A2 from the front and rear, the pipe cutting assembly 722 works to cut the long guide pipe, the pipe pulling fingers 7342 are loosened and move forward to vacate the feeding space, at the same time, the first pipe clamping fingers 7322 are driven by the guide pipe translation feeding drive 735 to move forward until the rear part of the guide pipe is located above the second guide pipe jig B2 on the rear side, the first pipe clamping fingers 7322 and the second pipe clamping fingers 7332 simultaneously continue to descend to place the front and rear parts of the long guide pipe in the front and rear second guide pipe jigs B2 respectively (the middle part of the long guide pipe naturally droops, and the two ends are carried and transported by the guide pipe jigs, so that the overall conveying space of the long guide pipe can be shortened, and the space for pulling and pulling the long guide pipe and other joint fittings in the subsequent assembly is provided), the first feeding pipe clamping assembly 732, the second feeding pipe clamping assembly 733 and the pipe pulling assembly 734 return to the original state to wait for pipe pulling feeding again. After the pipe cutting assembly 722 cuts the long guide pipe on the first set of pipe pulling feeding assemblies 731, the pipe cutting assembly 722 moves horizontally to the work position of another set of pipe pulling feeding assemblies 731 in the original state, after the pipe cutting assembly 722 is in place, another set of pipe pulling feeding assemblies 731 work like the first set of pipe pulling feeding assemblies 731 to pull out another set of guide pipes for feeding, that is, the first set of pipe pulling feeding assemblies 731 are in the discharging return process, and the second set of pipe pulling feeding assemblies 731 are in the pipe pulling. The pipe pulling feeding assembly 731 can pull and feed two long guide pipes at a time. After the two sets of pipe pulling feeding assemblies 731 work together, a total of four long guide pipes are fed to the guide pipe jigs, the guide pipe jigs move forward, and the subsequent empty guide pipe jigs wait for continuous feeding. The two sets of pipe pulling feeding assemblies 731 in the embodiment alternately pull and feed, which can save the return waiting time of the pipe pulling feeding assembly 731.

[0127] The second guide pipe feeding device 7 in the embodiment can reasonably arrange the feeding assemblies 711 on the guide pipe rack 710 to enable two sets of feeding assemblies 711 to be arranged on one side, and the pipe cutting assembly 722 is designed to be horizontally movable in the two sets of pipe pulling feeding assemblies 731, the pipe pulling assembly 734 and the second feeding pipe clamping assembly 733 are synchronously moved forward and backward, the two sets of pipe pulling feeding assemblies 731 alternately pull and feed, which can save the return waiting time of the pipe pulling feeding assembly 731, meet the long guide pipe feeding requirements of multiple workstations, and do not affect the long guide pipe feeding efficiency, and efficiently realize the long guide pipe feeding effect.

[0128] The first conduit feeding device 2 and the second conduit feeding device 7 are similar in structure, but different in that the first conduit A1 is shorter, so that no elongated tube is needed, the pipe cutting assembly does not need to move horizontally, and the conduit feeding needs to move horizontally multiple times to take the material, so that the space required is smaller, and the device structure is relatively simpler.

[0129] In this embodiment, the flat joint feeding assembly device 3 and the K joint feeding assembly device 4 are similar in structure, and the flat joint A4 and the K joint A3 are respectively bonded at both ends of the first conduit A1. In this embodiment, the conduit external glue feeding device 8 is arranged in the flat joint feeding assembly device 3, the K joint feeding assembly device 4, and the K joint and second conduit assembly device 5, so that the glue feeding and assembly operations are simultaneously completed in a single work station.

[0130] The feeding and assembly process of the flat joint A4 and the K joint A3 is briefly described as follows: the joint is conveyed to the front end through the vibration disc and the straight vibration, the first conduit jig is positioned, the conduit external glue feeding device 8 performs external glue feeding operation at one end of the first conduit, and then the joint clamping and grabbing device translates the joint to the conduit to assemble the joint with the conduit. The first assembly body C1 and the second assembly body C2 that are completed are placed back into the first conduit jig for continuous conveying.

[0131] As shown in Figure 17 A K joint and second conduit assembly device 5 is provided, specifically a K joint and second conduit assembly device for the inclined pipe interface of the K joint and the second conduit, which comprises a K joint positioning mechanism 51, a K joint lifting and taking-over and overturning mechanism 52, a first conduit clamping assembly 56, a K conduit clamping and docking assembly 57, a second conduit clamping mechanism 58, and a conduit external glue feeding device 8. The conduit external glue feeding device 8 is arranged with the first conduit jig B1 loaded with the second assembly body C2 and the second conduit jig B2 loaded with the second conduit A2 on the front and back sides.

[0132] The conduit external glue feeding device 8 comprises a glue feeding mechanism 81, a glue containing mechanism, and a glue feeding lifting source 82 for driving the glue feeding mechanism 81 to move up and down. The glue containing mechanism is connected with the glue feeding mechanism 81 and provides glue for the glue feeding mechanism 81.

[0133] The purpose of this work station is to connect the second assembly body C2 (the first conduit A1 + the flat joint A4 + the K joint A3) with the second conduit A2 to form a third assembly body C3 (the first conduit A1 + the flat joint A4 + the K joint A3 + the second conduit A2).

[0134] In the initial state of the second assembly body C2, the K joint A3 is in a natural inclined and vertical state, and is easy to shake with the first conduit jig B1 conveying and moving.

[0135] As shown in Figure 17As shown, the K-connector positioning mechanism 51 is located below the first catheter fixture B1 and faces the oblique tube interface A33 to position and clamp the K-connector A3. The K-connector lifting, picking, and flipping mechanism 52 is located above the first catheter fixture B1 to clamp and flip the K-connector A3 to unify the direction of the oblique tube interface A33. The second catheter clamping mechanism 58 is located above the second catheter fixture B2 to clamp the second catheter A2. The second catheter clamping mechanism 58 clamps the second catheter A2 and completes the catheter gluing operation in the catheter external gluing device 8. Then, the end of the second catheter A2 after gluing is assembled with the oblique tube interface A33 of the K-connector A3 on the K-connector lifting, picking, and flipping mechanism 52 to form a third assembly C3.

[0136] The second conduit clamping mechanism 58 includes a second conduit clamping assembly 581 for clamping and lifting the second conduit, and a second conduit horizontal movement assembly 582 for clamping and moving the front end of the second conduit A2 back and forth. The second conduit A2 is not clamped securely within the second conduit clamping assembly 581, and the conduit line can be pulled forward on the second conduit clamping assembly 581. This design ensures that the second conduit located above the second conduit jig B2 can be controlled by the second conduit clamping assembly 581 and returned to the second conduit jig B2 without affecting the gluing and assembly process at the front end of the second conduit. Furthermore, the second conduit horizontal movement assembly 582 cooperates to press-fit the front end of the second conduit A2 into the first conduit jig B1, allowing the first conduit jig B1 and the second conduit jig B2 to stably receive the third assembly C3 as a whole.

[0137] like Figures 18-20 As shown, the K-connector positioning mechanism 51 includes a positioning clamping finger assembly 511, a positioning lifting plate 512, a positioning lifting drive source 513, and a positioning translation drive source 514, wherein the positioning lifting drive source 513 is fixed on a frame (not shown in the figure), and the fixed end of the positioning translation drive source 514 is installed on the movable end of the positioning lifting drive source 513, and the movable end of the positioning translation drive source 514 faces the first catheter fixture B1 and is fixedly connected to the positioning lifting plate 512. The positioning clamping finger assembly 511 is installed on the positioning lifting plate 512, and the positioning clamping finger assembly 511 can be driven to move up and down and forward and backward. The positioning clamping finger assembly 511 includes a positioning clamping finger cylinder 5111, a positioning left clamping finger 5112 and a positioning right clamping finger 5113. The positioning left clamping finger 5112 and the positioning right clamping finger 5113 are respectively fixed on the left and right movable blocks of the positioning clamping finger cylinder 5111. The positioning clamping finger cylinder 5111 controls the positioning of the left clamping finger 5112 and the positioning of the right clamping finger 5113 to be apart or close.

[0138] The upper portions of the left and right positioning fingers 5112 and 5113 are oppositely defined with semicircular positioning grooves 5114 that accommodate the K-connector connector A31. The side of the right positioning finger 5113 facing away from the first catheter fixture B1 is provided with a horizontal lap 5115 extending toward the left positioning finger 5112. This lap 5115 is located below the semicircular positioning grooves 5114 and has a straight upper surface. A corresponding lap opening 5116 is provided on the back of the left positioning finger 5112, allowing the horizontal lap 5115 to pass through.

[0139] The present invention provides a K-joint positioning mechanism 51, which can provide preliminary positioning for K-joints that sag, dangle, or have inconsistent shapes. The crosspiece 5115 lifts the K-joint, aligning it horizontally and highlighting the oblique tube interface A33. This allows the K-joint to be positioned and clamped, improving the success rate and accuracy of the K-joint lifting, retrieving, and flipping mechanism 52, thereby enhancing overall assembly efficiency. Without the K-joint positioning mechanism 51, the K-joint lifting, retrieving, and flipping mechanism 52 can still grasp the K-joint, but the grasping result will be unstable, affecting the success rate of subsequent connection and assembly with the catheter.

[0140] The first catheter fixture B1 includes a translation base plate B11, a first clamping base plate B12, a second clamping base plate B13, a first catheter clamping block B14, a second catheter clamping block B15, and a third catheter clamping block B16. The front end of the second clamping base plate B13 is fixed below the rear end of the translation base plate B11, and the first clamping base plate B12 is fixed on the translation base plate B11. Multiple first clamping base plates B12 can be fixed on the translation base plate B11 to form a multi-station operation. The front and rear ends of the first clamping base plate B12 are respectively fixed with the first catheter clamping block B14 and the second catheter clamping block B15 for the placement of the front and rear pipe parts of the first catheter A1; the third catheter clamping block B16 is fixed on the rear end of the second clamping base plate B13 for the placement of the front part of the second catheter A2. A vertically extending positioning opening B17 is also provided in the middle of the second retaining base B13. This allows the K-connector A3 to freely hang and allows the positioning finger assembly 511 of the K-connector positioning mechanism 51 to pass through from bottom to top to position and clamp the K-connector A3. Positioning opening B17 can be a single opening or multiple openings corresponding in number to the first retaining base B12. The first, second, and third conduit clamping blocks B14, B15, and B16 are each equipped with an upward-facing conduit slot B18.

[0141] The third conduit clamping block B16 is below the first conduit clamping block B14 and the second conduit clamping block B15, has a certain height difference, and does not pursue being on the same plane, so that the K joint A3 can be in a relatively natural falling state, the inclined pipe interface A33 can be kept in a relatively flat state, the second conduit A2 can be flatly conveyed, and forcibly lifting the K joint A3 is avoided, and the weight of the K joint A3 itself is easy to pull the conduit, which causes peeling or corresponding detection point position.

[0142] The bottom of the translation base plate B11 can also be provided with a pulley B3 for promoting movement. The left and right ends of the translation base plate B11 can also be provided with jig limiting plates to be isolated from the adjacent first conduit jig.

[0143] In the present application, the first conduit jig B1 can carry the first conduit A1, the first assembly C1 and the second assembly C2, and cooperate with the second conduit jig B2 to carry the third assembly C3.

[0144] Since the second conduit A2 in the present embodiment is a long conduit, the second conduit jig B2 is divided into two parts, which clamp the front and rear parts of the second conduit A2 respectively, and the structure of the second conduit jig B2 is similar to that of the first conduit jig B1, but does not have a second clamping position base plate B13.

[0145] In the present embodiment, the K joint positioning process is as follows: the positioning finger cylinder 5111 first controls the positioning left finger 5112 and the positioning right finger 5113 to be in a separated open state, the left end of the crosspiece 5115 is located at the crosspiece gap 5116, the positioning translation driving source 514 drives the positioning finger assembly 511 to move forward so that the positioning finger assembly 511 is located directly below the K joint A3 of the first conduit jig B1, the positioning lifting driving source 513 drives the positioning finger assembly 511 to ascend, the joint part A31 of the K joint contacts the crosspiece 5115 and is lifted to make it flat (at this time, the straight pipe interface A32 and the inclined pipe interface A33 are located in front of the positioning finger assembly 511 and do not contact the positioning left finger 5112 and the positioning right finger 5113, and the inclined pipe interface A33 is inclined upward), then the positioning finger cylinder 5111 controls the positioning left finger 5112 and the positioning right finger 5113 to approach, the joint part A31 is always placed on the crosspiece 5115, until the positioning left finger 5112 and the positioning right finger 5113 are closed, the joint part A31 is placed between the two positioning semicircular grooves 5114, that is, the positioning process of the K joint A3 is completed, then the K joint lifting and taking mechanism 52 clamps the positioned K joint A3, the positioning left finger 5112 and the positioning right finger 5113 are opened again, the positioning finger assembly 511 is driven to move downward and retreat, and the next positioning work is waited.

[0146] As Figure 21As shown, the K joint lifting and picking turnover mechanism 52 is arranged opposite to the K joint positioning mechanism 51, and the first conduit jig B1 is located below the K joint lifting and picking turnover mechanism 52. The K joint lifting and picking turnover mechanism 52 comprises a K joint lifting assembly 53, a K joint turnover assembly 54, and a K joint clamping assembly 55. The K joint clamping assembly 55 is arranged in the K joint turnover assembly 54, the K joint turnover assembly 54 is installed at the lower part of the K joint lifting assembly 53, and the K joint clamping assembly 55 is driven to move up and down and to turn over by the K joint lifting assembly 53.

[0147] The K joint lifting assembly 53 comprises a lifting fixed plate 531 fixed on the rack by a lifting support. A clamping lifting driving source 532 is vertically arranged on the lifting fixed plate 531 and fixed on the lifting fixed plate 531. The movable end of the clamping lifting driving source 532 is downward and connected to a lifting top plate 533. A plurality of lifting guide columns 534 are arranged between the lifting fixed plate 531 and the lifting top plate 533 to improve the stability of the lifting top plate 533 moving up and down. The top part of the lifting guide column 534 is connected to a lifting limiting plate 535 to limit the descending height of the lifting top plate 533.

[0148] The K joint turnover assembly 54 is installed at the lower part of the lifting top plate 533, and the clamping lifting driving source 532 drives the lifting top plate 533 and the K joint turnover assembly 54 to move up and down. The K joint turnover assembly 54 comprises a turnover left support plate 541 and a turnover right support plate 542 fixedly installed at the left and right sides of the bottom of the lifting top plate 533, respectively. A turnover plate 543 is rotatably connected between the turnover left support plate 541 and the turnover right support plate 542. The turnover plate 543 is connected with the turnover right support plate 542 through a driving turnover shaft arranged on the turnover right support plate 542. The turnover plate 543 is connected with the turnover left support plate 541 through a driven turnover shaft arranged on the turnover left support plate 541. A cylindrical gear 544 is further connected to the outside of the driving turnover shaft. A rack 545 is engaged with the cylindrical gear 544. The rack 545 can slide back and forth along a guide rail 546 installed on the turnover right support plate 542. The K joint turnover assembly 54 further comprises a turnover driving source 547. The movable end of the turnover driving source 547 is fixedly connected to the rack 545 through a turnover connecting block 548. The fixed end of the turnover driving source 547 is fixedly connected to the turnover right support plate 542 through a support. The turnover driving source 547 drives the rack 545 to move back and forth, drives the cylindrical gear 544 to rotate, and further drives the driving turnover shaft and the turnover plate 543 to rotate, so as to realize the turnover effect of the turnover plate 543.

[0149] In combination Figures 22-24As shown, the K-connector clamping assembly 55 includes several groups of clamping assemblies 551, and the clamping assembly 551 includes a K-connector clamping drive source 552 and a left clamping finger 553 and a right clamping finger 554. The fixed end of the K-connector clamping drive source 552 is fixedly installed on the flip plate 543, and the K-connector clamping drive source 552 controls the opening and closing of the left clamping finger 553 and the right clamping finger 554. On the opposite side of the left clamping finger 553 and the right clamping finger 554, there are provided inwardly convex clamping finger protrusions 555, and the clamping finger protrusions 555 are provided with a clamping inclined groove 5551 and a clamping transverse groove 5552, wherein the clamping inclined groove 5551 can accommodate the oblique tube interface A33, and the clamping transverse groove 5552 can accommodate the straight tube interface A32, and the angle between the clamping inclined groove 5551 and the clamping transverse groove 5552 is 45 degrees (matching the K-connector), and the clamping transverse groove 5552 is a through groove with openings at the front and rear ends, and the clamping inclined groove 5551 and the clamping transverse groove 5552 are connected and intersected, and a clamping circular groove 5553 is provided at the intersection, and the intersection of the clamping inclined groove 5551 and the clamping transverse groove 5552 is processed into a circular groove, which can effectively expand the accommodating space of the K-connector and avoid material jamming at the intersection of the oblique tube interface A33 and the straight tube interface A32.

[0150] A left duct clamping plate 556 is installed in front of the clamping finger protrusion 555 on the left clamping finger 553 and on the inner side of the left clamping finger 553. The thickness of the left duct clamping plate 556 is less than the thickness of the clamping finger protrusion 555. The front end of the left duct clamping plate 556 extends to the right and is provided with a side T-shaped left clamping plate protrusion 5561, a long strip-type clamping plate horizontal bar 5562 and a left side protrusion 5563 below the clamping plate horizontal bar 5562. At the same time, the clamping horizontal groove 5552 is also located below the clamping plate horizontal bar 5562.

[0151] A right conduit clamping plate 557 is mounted in front of and inside the right material clamping finger 554, in front of the finger protrusion 555. The thickness of the right conduit clamping plate 557 is less than that of the finger protrusion 555, and a right conduit clamping plate protrusion 5571 extends leftward from the front end of the right conduit clamping plate 557. The right conduit clamping plate protrusion 5571 corresponds to the left side protrusion 5563 and is also located below the clamping plate cross bar 5562. The clamping plate cross bar 5562 can move left and right above the right conduit clamping plate protrusion 5571. The bottoms of both the left material clamping finger 553 and the right material clamping finger 554 are equipped with an inverted L-shaped connector slot 558. The connector slot 558 opens outward, with its vertical side perpendicular to the material clamping cross slot 5552. The connector slot 558 accommodates the side of the connector portion A31 of the K connector to prevent material from getting stuck.

[0152] by Figure 25 As shown, in order to conveniently illustrate the effect of the clamping assembly 551 clamping the second assembly C2, only the left clamping finger 553 and the K connector A3 equipped with the first conduit A1 are shown. The initial state of the clamping assembly 551 is that the clamping groove 5552 is in a horizontal state with the opening facing forward.Figure 23 、 24 , it can be seen that when the left clamping finger 553 and the right clamping finger 554 are closed, the straight tube interface A32 of the K connector is located between the clamping transverse grooves 5552 on both sides, and the front end of the straight tube interface A32 is located between the left clamping plate 556 and the right clamping plate 557 of the catheter; the oblique tube interface A33 is located between the clamping oblique grooves 5551 on both sides, and the outer end of the oblique tube interface A33 is exposed outside the left clamping finger 553 and the right clamping finger 554 for the K catheter clamping docking assembly 57 to clamp and assemble the second catheter A2, and the first catheter A1 is clamped under the clamping plate horizontal bar 5562, between the left protrusion 5563 and the right protrusion 5571 of the clamping plate. The clamping plate horizontal bar 5562 can press the first catheter A1 underneath it, ensuring that the left protrusion 5563 and the right protrusion 5571 of the clamping plate can clamp the first catheter A1 and position it in the left and right directions, so that it can be conveniently put back into the fixture later.

[0153] like Figure 26 As shown in FIG. 1 , it is a schematic diagram of the K-joint positioning, clamping and flipping process. FIG. (1) shows the original natural oblique state of the K-joint; FIG. (2) shows the positioning clamping finger assembly 511 of the K-joint positioning mechanism 51 flattens the K-joint, so that the straight tube interface A32 of the K-joint is in a straight state, which is convenient for the clamping transverse groove 5552 of the clamping assembly 551 to position and pick up materials in the front and rear horizontal directions; FIG. (3) shows that the clamping fingers of the clamping assembly 551 continue to correct and position the oblique tube interface A33 in the left and right directions during the clamping process, so as to regularize the K-joint into a unified state; FIG. (4) shows that the clamping assembly 551 is uniformly flipped 45 degrees, so that the oblique tube interface A33 is uniformly horizontally facing backwards, completing the entire positioning, clamping and flipping effect.

[0154] like Figure 28 、 29As shown, the first pipe clamping assembly 56 is mounted on the lifting top plate 533 and synchronously lifted with the lifting top plate 533 and the K joint clamping assembly 55. The first pipe clamping assembly 56 comprises a first pipe transverse driving source 561, a pipe clamping left fixed plate 562 and a pipe clamping right fixed plate 563. The fixed end of the first pipe transverse driving source 561 is fixedly connected with the lifting top plate 533. The pipe clamping left fixed plate 562 and the pipe clamping right fixed plate 563 are connected with the movable end of the first pipe transverse driving source 561 through the clamping plate connecting blocks respectively. The first pipe transverse driving source 561 controls the left and right transverse movement of the pipe clamping left fixed plate 562 and the pipe clamping right fixed plate 563. The pipe clamping left fixed plate 562 and the pipe clamping right fixed plate 563 are arranged in a staggered manner in front and back. A plurality of pipe clamping left clamping fingers 564 are arranged on the pipe clamping left fixed plate 562 in a spaced manner. The pipe clamping left clamping fingers 564 are arranged on the side facing the pipe clamping right fixed plate 563. A plurality of pipe clamping right clamping fingers 565 are arranged on the pipe clamping right fixed plate 563 in a spaced manner. The pipe clamping left clamping fingers 564 are provided with pipe clamping left protrusions 566 at the right end of the bottom. The pipe clamping right clamping fingers 565 are provided with pipe clamping right protrusions 567 at the left end of the bottom. The pipe clamping left clamping fingers 564 are provided with pipe limiting sheets 568 on the front and back sidewalls of the middle part in the right direction. The pipe clamping right clamping fingers 565 are provided with pipe limiting grooves 569 in the middle part in the front and back sidewalls in a corresponding recessed manner. The pipe limiting sheets 568 transversely move along the pipe limiting grooves 569, which ensures the uniform stability of the relative movement of the pipe clamping left and right clamping fingers, thereby improving the stability during pipe clamping.

[0155] The middle part of the pipe clamping left clamping fingers 564 and the pipe clamping right clamping fingers 565 is transversely hollowed out to form a downwardly open inverted U-shaped groove, which can accommodate the first pipe clamping block 5B14 on the first pipe jig 5B1.

[0156] The first pipe transverse driving source 561 drives and controls the opening and closing of the pipe clamping left clamping fingers 564 and the pipe clamping right clamping fingers 565. When the pipe clamping left protrusions 566 and the pipe clamping right protrusions 567 are in contact, the upper end of the pipe clamping left protrusions 566, the upper end of the pipe clamping right protrusions 567, the right sidewall of the pipe clamping left clamping fingers 564, the left sidewall of the pipe clamping right clamping fingers 565 and the lower end surface of the pipe limiting sheets 568 jointly form a pipe accommodating space (such as a thick line box shown in the middle part of the figure). Figure 29 The first pipe A1 is clamped.

[0157] The first catheter clamping assembly 56 cooperates with the K joint clamping assembly 55 to integrally pick and place the second assembly C2, avoiding damage to the first catheter body caused by pulling up and down in the first catheter jig B1. At the same time, the design of the first catheter clamping assembly 56 reduces the number of clamping finger driving sources. Through the staggered design of front and back and left and right, only one first catheter horizontal movement driving source 561 is needed to control the clamping of multiple catheters, which can save costs, ensure clamping stability, and at the same time improve production efficiency.

[0158] As shown in Figure 27 The K catheter clamping docking assembly 57 is located at the rear end of the K joint clamping assembly 55. The K catheter clamping docking assembly 57 includes a docking lifting driving source 571, a docking lifting connecting plate 572, a docking clamping driving source 573, a docking left clamping finger 574, and a docking right clamping finger 575. The fixed end of the docking lifting driving source 571 is fixedly connected with the lifting fixed plate 531 through a docking connecting block 578. A guide column can be further arranged between the docking connecting block 578 and the docking lifting connecting plate 572 to make the lifting process of the docking lifting connecting plate 572 more stable. The movable end of the docking lifting driving source 571 is connected with the docking lifting connecting plate 572. The bottom surface of the docking lifting connecting plate 572 is fixedly provided with a plurality of docking clamping driving sources 573. The docking clamping driving sources 573 drive the opening and closing of the docking left clamping finger 574 and the docking right clamping finger 575. The opposite surfaces of the docking left clamping finger 574 and the docking right clamping finger 575 are provided with semicircular inclined pipe clamping grooves 576. The rear end of the inclined pipe clamping groove 576 is provided with an outwardly expanded catheter guide groove 577.

[0159] The inclined pipe clamping grooves 576 of the docking left clamping finger 574 and the docking right clamping finger 575 form a complete circle to clamp the end of the inclined pipe interface A33. The outwardly expanded guide structure of the catheter guide groove 577 promotes the end of the second catheter A2 to extend into the catheter guide groove 577 and then insert into the inclined pipe interface A33. The arrangement of the K catheter clamping docking assembly 57 can guide the connection and assembly of the second catheter A2 and the K joint inclined pipe interface A33, improving the assembly success rate.

[0160] The working process of the station is as follows: the first conduit jig B1 carrying the second assembly C2 and the second conduit jig B2 carrying the second conduit A2 are positioned at the same time; the second conduit clamping assembly 581 and the second conduit horizontal moving assembly 582 of the second conduit clamping mechanism 58 clamp the front part of the second conduit A2 on the second conduit jig B2 close to the glue adding mechanism 81; the glue adding mechanism 81 is raised; the second conduit horizontal moving assembly 582 clamps the front end of the second conduit A2 and pulls it forward to extend into the glue adding mechanism 81; the glue adding mechanism 81 adds glue to the front end of the second conduit A2; after the glue adding is completed, the second conduit horizontal moving assembly 582 retreats; the glue adding mechanism 81 is lowered; and the second conduit A2 waits for assembly; while the second conduit clamping mechanism 58 is working, the positioning clamp finger assembly 511 of the K joint positioning mechanism 51 is raised; the positioning left clamp finger 5112 and the positioning right clamp finger 5113 pass through the positioning through hole B17 of the first conduit jig B1 from bottom to top to lift the K joint, so that the straight pipe interface A32 of the K joint is in a flat state; then the clamp assembly 551 of the K joint clamping assembly 55 clamps the front part of the K joint; the outer end of the inclined pipe interface A33 is exposed to the outside; the positioning clamp finger assembly 511 is lowered; the first conduit clamping assembly 56 clamps the front part of the first conduit A1 on the first conduit jig B1; the K joint lifting assembly 53 controls the K joint turnover assembly 54, the K joint clamping assembly 55 and the first conduit clamping assembly 56 to be raised at the same time; then the K joint turnover assembly 54 controls the turnover plate 543 to turn over to make the clamp assembly 551 turn over by 45 degrees as a whole, so that the inclined pipe interface A33 is uniformly horizontal and faces backward; the K conduit clamping docking assembly 57 controls the docking left clamp finger 574 and the docking right clamp finger 575 to be lowered and clamp the outer end of the inclined pipe interface A33 exposed to the outside of the clamp assembly 551; the second conduit horizontal moving assembly 582 controls the front end of the second conduit A2 to move forward; the front end of the second conduit A2 extends into the conduit guide groove 577 and then inserts into the inclined pipe interface A33 in the inclined pipe clamping groove 576; after the assembly of the second conduit A2 and the inclined pipe interface A33 of the K joint is completed to form the third assembly C3, the K conduit clamping docking assembly 57 controls the docking left clamp finger 574 and the docking right clamp finger 575 to be opened and raised; the second conduit clamping assembly 581, the second conduit horizontal moving assembly 582, the clamp assembly 551 and the first conduit clamping assembly 56 are controlled to be lowered at the same time; and the first conduit jig B1 and the second conduit jig B2 jointly carry the third assembly C3. Then the second conduit clamping assembly 581, the second conduit horizontal moving assembly 582, the clamp assembly 551 and the first conduit clamping assembly 56 are raised back to the original position to wait for the next assembly.

[0161] The device realizes the assembly of the medical joint with the inclined pipe interface and the catheter, through the setting of the K joint positioning mechanism 51 and the K joint lifting material taking and overturning mechanism 52, the K joint A3 on the first catheter jig B1 is positioned and clamped in turn, finally the inclined pipe interface A33 of the K joint is uniformly oriented, the uniform high-precision assembly of the K joint and the second catheter is realized, and the overall device structure is ingenious and high in assembly efficiency.

[0162] As shown in Figures 30-37 , the glue adding mechanism 81 in the embodiment is a backflow type catheter outer glue adding mechanism, which comprises a glue adding backflow box 811 and a box cover 812, and a glue head fixing block 813 is fixed in the glue adding backflow box 811. A glue head assembly 814 is arranged on the glue head fixing block 813.

[0163] As shown in Figure 30 , 31 , the glue adding backflow box 811 has a box body 8111, and the upper end of the box body 8111 is open. The box cover 812 is fixed on the box body 8111. Four glue adding windows 8112 are arranged on the front surface of the box body 8111, and the glue adding windows 8112 are opposite to the catheter workstations to be added with glue. A pipe placing opening 8113 is arranged on the back surface of the box body 8111, and the pipe placing opening 8113 is a groove with an opening upward. The pipe placing opening 8113 can be used to support a glue feeding pipeline (not shown in the figure), so that the joint of the glue feeding pipeline is flush with the channel feeding port 8133 of the glue head fixing block 813, and the smoothness of glue feeding is ensured. A glue adding base 8115 is further arranged in the box body 8111, and the glue adding base 8115 is fixed on the bottom surface of the box body 8111. The glue adding base 8115 is block-shaped, and the glue head fixing block 813 is positioned and installed on the glue adding base 8115 through positioning members. It should be noted that the positioning members are a general concept in the embodiment, and the fittings for installation, fixation and positioning are collectively referred to as positioning members, which are not subdivided here, and can actually be screw rods, screws, positioning columns and the like. The bottom of the box body 8111 is provided with a glue returning hole 8114 penetrating upward and downward, and a glue feeding joint (not shown in the figure) can be arranged to return the remaining glue in the box body 8111 to a glue containing mechanism (not shown in the figure) through the glue returning hole 8114. The glue containing mechanism comprises a circulating pump and a glue barrel, and is used to supply glue to the glue adding mechanism 81 in circulation.

[0164] As shown in Figures 32 , 33 , the glue head fixing block 813 is block-shaped, and the back portion thereof is outwardly convex to form a fixing convex portion 8131. An installation through hole 8138 penetrating upward and downward is arranged on the fixing convex portion 8131, and the positioning members pass through the installation through hole 8138 to reach the glue adding base 15, so that the glue head fixing block 813 is completely fixed on the glue adding base 8115.

[0165] A glue flow channel 8132 is provided transversely through the upper portion of the glue head fixing block 813. The end of the glue flow channel 8132 is a glue flow outlet 8139. The glue flow channel 8132 and the mounting hole 8138 are arranged in a front-to-back offset arrangement and are not connected. A rearward-facing glue inlet 8133 is also provided on the back of the glue head fixing block 813. The glue inlet 8133 is connected to the glue flow channel 8132. The glue inlet 8133 is used to connect to the glue inlet pipe to introduce glue into the glue head fixing block 813. The position of the glue inlet 8133 corresponds to the tube placement port 8113.

[0166] A glue adding through hole 8134 is further provided in the middle of the glue head fixing block 813 , which runs through the front and back, and the glue adding head assembly 814 is placed in the glue adding through hole 8134 .

[0167] A glue adding channel 8135 communicating with the glue flow channel 8132 is provided between the upper end of the glue adding hole 8134 , and a glue outlet channel 8136 opening downward is provided at the lower end of the glue adding hole 8134 . The glue adding channel 8135 and the glue outlet channel 8136 are coaxially arranged.

[0168] A downward-facing glue return channel 8137 is also provided on the side of the glue head fixing block 813. This channel 8137 communicates with the glue flow channel 8132. The purpose of the glue return channel 8137 and the glue flow outlet 8139 is to relieve pressure and prevent a large amount of glue from entering the glue filling through hole 8134 from the glue filling flow channel 8135 and then entering the glue filling annular gap 8143 of the glue filling head assembly 814, causing splashing glue. Excessive glue can also affect the effectiveness of glue filling outside the catheter, making it easy for it to overflow and enter the catheter tube. The provision of the glue return channel 8137 and the glue flow outlet 8139 can divert most of the glue to the side, effectively controlling the amount of glue entering the glue filling annular gap 8143 and creating a glue filling environment where circulation and no dripping occur.

[0169] In this embodiment, two glue adding head assemblies 814 can be installed on one glue head fixing block 813, and glue adding operations can be performed on two catheters at the same time. The glue in the glue flow channel 8132 supplies glue to the two glue adding head assemblies 814 at the same time, thereby improving the efficiency of catheter glue adding and assembly.

[0170] like Figures 34-37 As shown, the glue filling head assembly 814 includes a glue filling head 8141, a glue filling base 8142, a glue filling annular gap 8143, and a limiting rod 8144. The glue filling base 8142 is inserted into the glue filling head 8141, and the limiting rod 8144 is inserted into the rear portion of the glue filling base 8142. The glue filling annular gap 8143 is formed between the glue filling head 8141 and the glue filling base 8142 to allow glue to flow. The glue filling head 8141 of the glue filling head assembly 814 is fixed to the glue head fixing block 813 by a positioning member.

[0171] The glue feeding head 8141 is T-shaped, with a horizontal mounting portion 815 and a longitudinal, rearward-facing glue feeding portion 816. A pipe inlet 8151 is located in the middle of the mounting portion 815. The diameter of the pipe inlet 8151 is slightly larger than the outer diameter of the conduit, and the front end of the pipe inlet 8151 has a guide flare 8152. The glue feeding portion 816 is annular and cylindrical, with a receptacle 8161 that opens rearward and has the same diameter from front to back. The pipe inlet 8151 communicates with the receptacle 8161, and the inner diameter of the receptacle 8161 is larger than that of the pipe inlet 8151. The front end of the receptacle 8161 forms a glue flow bottom wall 8162. Two through-flow openings 8163 are provided on the periphery of the glue inlet 816: an upstream glue inlet 8163-1 and a downstream glue inlet 8163-2. These openings 8163-1 and 8163-2 are coaxially arranged vertically. When the glue filling head 8141 is installed, the upstream glue inlet 8163-1 interfaces with the glue filling channel 8135, while the downstream glue inlet 8163-2 interfaces with the glue outlet channel 8136. The outer diameter of the glue inlet 816 matches the inner diameter of the glue filling hole 8134.

[0172] A glue head mounting hole 8153 is provided on the mounting portion 815 of the glue adding head 8141. The glue adding head 8141 is fixed to the glue head fixing block 813 by a positioning piece passing through the glue head mounting hole 5153. Positioning installation is required here to ensure that the upstream glue port 8163-1 is aligned with the glue adding channel 8135 so that glue can enter the glue adding head assembly 814.

[0173] The glue filling base 8142 is annular and cylindrical, with a longitudinal hollow in the middle portion having a conduit cavity 817. The inner diameter of the conduit cavity 817 corresponds to the pipe inlet 8151, and the rear portion of the conduit cavity 817 is expanded outward to form an anti-sticking cavity 8171. Figure 11 As shown, in this embodiment, the end of the second conduit A2 is accommodated in the anti-sticking cavity 8171, and the excess glue in the conduit cavity 817 can flow out along the anti-sticking cavity 8171, preventing glue from accumulating at the end of the conduit and entering the tube. The outer wall of the glue-filling base 8142 gradually decreases in diameter from back to front, including a supporting portion 818, a transition portion 819 and a glue flow portion 8110, that is, the outer diameters of the supporting portion 818, the transition portion 819 and the glue flow portion 8110 gradually decrease, wherein the outer diameter of the transition portion 819 is adapted to the inner diameter of the receptacle cavity 8161, that is, the outer diameter of the glue flow portion 8110 is smaller than the inner diameter of the receptacle cavity 8161, and in addition, the total front-to-back length of the transition portion 819 and the glue flow portion 8110 is less than the cavity depth of the receptacle cavity 8161. A front end surface of the abutting portion 818 forms an abutting step 8181 . The outer diameter of the abutting portion 818 is equivalent to the outer diameter of the glue feeding portion 816 and can also be accommodated in the glue filling through hole 8134 .

[0174] The cavity wall of the anti-sticking cavity 8171 is provided with two upper and lower radial through limiting sockets 8182 for inserting the limiting rod 8144. The limiting rod 8144 has the following functions: 1. limiting the depth of the inserted catheter and limiting the glue adding length; 2. touching and destroying the glue film possibly formed on the catheter port, so as to avoid the glue being blocked in the catheter port to form a defective product during subsequent assembly with other accessories. The limiting socket 8182 is in contact with the hole wall of the glue adding through hole 8134, so as to ensure that the limiting rod 8144 is installed within the hole cavity of the glue adding through hole 8134, and the limiting rod 8144 can be prevented from falling out of the glue adding base 8142. The glue adding through hole 8134 has a supporting and blocking effect.

[0175] When the glue adding base 8142 and the glue adding head 8141 are assembled, the transition part 819 and the glue flowing part 8110 are tightly inserted into the accommodating cavity 8161, the glue flowing part 8110 corresponds to the position of the glue flowing port 8163, and the tail end of the glue adding head 8141 is in contact with the abutting step 8181. Since the outer diameter of the glue flowing part 8110 is smaller than the inner diameter of the accommodating cavity 8161, and the total length of the transition part 819 and the glue flowing part 8110 is smaller than the cavity front and back depth of the accommodating cavity 8161, the gap between the glue flowing part 8110 and the peripheral wall and the glue flowing bottom wall 8162 of the accommodating cavity 8161 forms the glue adding annular gap 8143, and the glue adding annular gap 8143 close to the communication port of the catheter accommodating cavity 817 is the glue adding port 81431.

[0176] When the catheter is glued, the catheter end is inserted into the catheter accommodating cavity 817 of the glue adding base 8142 from the pipe inlet 8151, the front end of the catheter is located in the anti-sticking cavity 8171 and in contact with the limiting rod 8144, the glue flows into the upper glue flowing port 8163-1 of the glue adding head 8141 from the glue adding flow channel 8135, the glue circulates along the glue adding annular gap 8143, and a flowing glue liquid surface is formed at the glue adding port 81431. Since the amount of glue flowing along the glue adding annular gap 8143 is very small, it will not directly flow downward. During the forward or backward movement of the catheter, the catheter outer wall contacts the glue adding port 81431, and the glue liquid is guided to the catheter outer wall to form a glue adding effect.

[0177] In this embodiment, the installation process of the glue adding mechanism of the reflux type is as follows:

[0178] The glue adding base 8142 and the glue adding head 8141 are assembled together by a tight fit, then the limiting rod 8144 is inserted into the limiting insertion hole 8182 of the glue adding base 8142, as a whole glue adding head assembly 814, the glue adding part 816 is inserted into the glue adding through hole 8134 in the rear direction, the installation part 815 is abutted against the front wall of the glue head fixing block 813, the glue adding head 8141 and the glue head fixing block 813 are fixed on the glue head fixing block 813 by the positioning member; then the glue head fixing block 813 assembled with the glue adding head assembly 814 is positioned and fixed on the glue adding base 8115 in the box body 8111 by the positioning member, the glue adding head 8141 is opposite to the glue adding window 8112. The channel glue inlet 8133 on the glue head fixing block 813 is connected with the glue adding pipeline, the pipeline body of the glue adding pipeline can be placed in the pipe placing opening 8113, the bottom of the glue returning hole 8114 is connected with the glue flowing joint and the glue returning pipeline (not shown in the figure), the glue adding pipeline and the glue returning pipeline are respectively connected with the glue containing mechanism, the glue containing mechanism is internally provided with glue and a circulating pump. Then the box cover 812 is covered on the box body 8111, forming a relatively closed glue adding working environment.

[0179] The glue adding process of the glue adding mechanism in the embodiment is as follows:

[0180] The glue containing mechanism is opened, the glue flows into the glue flowing channel 8132 from the channel glue inlet 8133 of the glue adding pipeline, flows laterally along the glue flowing channel 8132, most of the glue flows out of the glue head fixing block 813 from the glue returning channel 8137 and the glue flowing outlet 8139, a small part of the glue flows into the glue adding through hole 8134 from the glue adding flow channel 8135, that is, into the glue adding head assembly 814. Specifically, the glue flows downward from the glue adding flow channel 8135 into the upper glue inlet 8163-1 of the glue adding head 8141, circulates along the glue adding annular gap 8143, and forms a flowing glue liquid surface at the glue adding port 81431. The glue flows downward along the glue adding annular gap 8143 and the lower glue inlet 8163-2, flows out of the glue adding head assembly 814, and finally flows out of the glue head fixing block 813 along the glue outlet flow channel 8136. The glue flowing out of the glue head fixing block 813 (including the glue overflowing from the glue adding head assembly 814) falls to the bottom of the box body 8111, and finally flows out of the glue returning box 811 along the glue returning pipeline to the glue containing mechanism;

[0181] When the catheter needs to be glued, the catheter end is inserted into the catheter containing cavity 817 of the glue adding base 8142 from the pipe inlet 8151, the catheter front end is located in the anti-sticking cavity 8171 and abuts against the limiting rod 8144. In the process of moving forward or backward, the catheter outer wall contacts the glue adding port 81431, the glue liquid is introduced to the catheter outer wall to form a glue adding effect; after reaching the predetermined glue adding time, the catheter is moved out of the glue returning box 811 by the mechanical hand, the glue adding process is completed, and the next batch of catheters is waiting for glue adding;

[0182] When the daily production task is completed, the glue circulating mechanism stops running.

[0183] In the embodiment, the glue adding mechanism 81 is connected to the glue adding lifting source 82 at the bottom in specific use, and is arranged between the second conduit conveying line and the K joint lifting and taking material and overturning mechanism 52. After the second conduit is in place, the glue adding mechanism 81 is driven to rise by the glue adding lifting source 82, the second conduit extends into the glue adding mechanism 81 to add glue, and after the glue adding is completed, the second conduit is withdrawn, the glue adding mechanism 81 is lowered to release the assembly space, and the second conduit with glue is directly assembled with the K joint, so that the glue adding and assembly work are simultaneously completed at the same station.

[0184] The conduit outer glue adding device 8 provided by the embodiment can automatically add glue to the outer wall of the conduit through the circulation and backflow of the glue, can stably provide the glue amount, and can make the glue adding action process simpler. The conduit in and out of the glue adding head assembly 4 can complete the conduit outer glue adding effect, the glue adding process does not need a mechanical hand, automatic operation, and the operation environment is relatively closed, so that the volatile odor of the glue is reduced as much as possible, and the working environment is greatly improved. In the application, the glue containing and glue adding are integrated, the structure is more compact, and there is no front and rear and upper shielding, so that the conduit outer glue adding device 8 can be arranged between the conduit conveying line and the joint discharge port to be assembled. The conduit completes the glue adding and assembly work at the same station, the whole device can reduce the original glue adding required station space, the whole assembly device structure is more simple and compact, and the cost is also reduced and controlled.

[0185] After the third assembly C3 is assembled, the first conduit jig B1 and the second conduit jig B2 on which the third assembly C3 is classified and taken down by the product discharging device 6, and according to the detection result, the products are respectively placed on the defective product conveying line and the finished product conveying line, the whole machine is completed, and the empty first conduit jig B1 and the second conduit jig B2 are lowered on the conveying line to circulate.

[0186] Embodiment two

[0187] Compared with embodiment one, as Figures 38-46As shown, the embodiment provides a rotary glue adding mechanism, which comprises a glue storage box 831, a glue adding box 832, a glue adding part 833, a rotating assembly 834, a rotating driving part 835, and a glue valve 836. The glue is pressed from the glue storage mechanism to the glue storage box 831 by the corrosion-resistant electromagnetic valve. The glue storage box 831 and the glue adding box 832 are connected through a communication joint 837 and are connected at the bottom through a connecting block. The communication joint 837 is an empty tubular structure, which ensures that the glue liquid level in the glue storage box 831 is level with the glue liquid level in the glue adding box 832. At the same time, it also ensures that the glue input of the glue adding box 832 is carried out in a relatively closed condition. The glue adding box 832 and the rotating assembly 834 are arranged and fixed on a fixed bottom plate 839. The glue adding lifting driving source can be connected with the fixed bottom plate 839 to drive the whole glue adding mechanism to lift. The glue adding part 833 is fixed at the front end of the rotating shaft 8341 of the rotating assembly 834 and is driven to rotate synchronously with the rotating shaft 8341 by the rotating driving part 835.

[0188] As shown, Figures 38-40 As shown, the glue storage box fixed bottom plate 831 comprises a glue storage box body 8311, a glue ball 8312, a glue liquid level sensor 8313, and a glue storage box cover plate 8314. The middle part of the glue storage box body 8311 is provided with a partition plate 83111, which divides the glue storage box body 8311 into a front and rear arranged glue inlet area 83112 and a ball stabilizing area 83113. The bottom of the partition plate 83111 is provided with a glue flow port 83114 for connecting the glue inlet area 83112 and the ball stabilizing area 83113. The side wall of the glue inlet area 83112 is provided with a glue storage box glue inlet port 83115, which is communicated with the “glue storage and pressure mechanism”. The side wall opposite to the glue tank 832 of the ball stabilizing area 83113 is provided with a glue storage box glue outlet port 83116. The ball stabilizing area 83113 is provided with a glue ball 8312. The bottom of the glue ball 8312 is fixed with a ball detection head 83131. The bottom of the glue storage box body 8311 is inserted with a glue liquid level sensor 8313. The ball detection head 83131 is located above the glue liquid level sensor 8313. In this way, a certain space is ensured between the bottom of the glue ball 8312 and the bottom surface of the glue storage box body 8311. The minimum amount of glue can ensure the supply amount of glue in the glue tank 832, and the amount of glue in the glue storage box 831 can be monitored. When the ball detection head 83131 at the bottom of the glue ball 8312 contacts the glue liquid level sensor 8313, the glue valve 835 is started to press the glue from the “glue storage mechanism” into the glue storage box 831. The four walls of the ball stabilizing area 83113 are provided with ball positioning protrusions 83117 for limiting the lifting track of the glue ball 8312, so that the ball detection head 83131 at the bottom of the glue ball 8312 can be aligned with the glue liquid level sensor 8313, and the sensing result is stable and accurate. The glue storage box body 8311 is also covered with a cover plate 8314. The glue flows in a relatively closed space, which effectively reduces the volatilization of the glue.

[0189] The glue storage box 831 has a glue floating ball 8312 and a liquid level sensor 8313, which monitors the amount of glue in the glue storage box 831 in real time. The glue storage box 831 is connected with the glue adding box 832 using a hollow joint to ensure that the liquid level of the glue in the glue storage box 831 is level with the liquid level of the glue in the glue adding box 832. The glue storage box 831 is provided and the amount of glue in the box is monitored in real time, so that automatic glue feeding of the glue storage box 831 can be realized, and the amount of glue in the glue adding box 832 is ensured to be automatic glue feeding, thereby improving the degree of automation of the overall mechanism.

[0190] As shown in FIGS. 41, Figure 38 , 39 The glue adding box 832 includes a glue tank 8321 and a glue tank cover plate 8322, and a plurality of glue adding members 833 are arranged side by side in the glue tank 8321.

[0191] Glue adding detection ports 83212 and glue adding feeding ports 83211 are respectively formed on the left and right side walls of the glue tank 8321, and the glue adding detection ports 83212 and the glue adding feeding ports 83211 are arranged at the same height to facilitate real-time monitoring of the amount of glue in the glue adding box 832 and the glue storage box 831, wherein the glue adding feeding ports 83211 are horizontally opposite to the glue storage box outlet 83116 of the glue storage box 831, and the two ports are connected through a communication joint 837. The front surface of the glue tank 8321 is provided with a plurality of glue adding ports 83213, and the glue adding ports 83213 are provided with guide flares outward; the back surface of the glue tank 8321 is provided with a plurality of rotary connection ports 83214, and the number of the rotary connection ports 83214, the glue adding ports 83213 and the glue adding members 833 are consistent. The side wall of the glue tank 8321 provided with the glue adding detection port 83212 is further provided with a glue adding observation port 83215, which is located obliquely above the glue adding detection port 83212, and the bottom point of the glue adding observation port 83215 is flush with the bottom point of the rotary connection port 83214. This can prevent the amount of glue from being higher than the bottom point of the rotary connection port 83214, and further prevent the glue from overflowing from the rotary connection port 83214. The glue adding observation port 83215 is an air outlet, and the glue tank 8321 cannot be completely sealed, which can simultaneously warn the maximum amount of glue, and if the amount exceeds, the glue will overflow from the port.

[0192] The glue adding detection port 83212 is connected with a glue tank detection joint 83217 to further monitor the amount of glue in the glue adding box 832, and the bottom of the glue tank detection joint 83217 is connected with a side right angle joint 83216. The side right angle joint 83216 is directly connected to the glue containing mechanism through a glue pipe, so that the glue in the glue storage box 831 and the glue adding box 832 reaches a balance of feeding and discharging. The bottom of the glue tank 8321 is further provided with a glue adding outlet, and the glue adding outlet is connected with a bottom right angle joint 83218 for guiding the residual glue during shutdown, and the right angle joint 83216 at this position can also block the glue adding outlet to prevent glue from leaking out during operation.

[0193] As shown in Figures 42-44 The glue adding head 833 includes a glue adding disc 83311 and a glue head connecting part 83312. The glue adding disc 83311 is in a disc shape and is provided with a front-to-back through pipe inlet 83313 in the middle part. A plurality of radial glue inlet channels 83314 are arranged between the outer wall of the glue adding disc 83311 and the peripheral wall of the pipe inlet 83313, and the glue inlet channels 83314 are uniformly arranged in a circumferential direction.

[0194] The glue adding head 833 includes a glue adding disc 83311 and a glue head connecting part 83312.
