Description

Technical Field

[0001] The present invention relates to the technical field of medical device equipment, and particularly relates to an assembly device for a double-attached tube of a waste liquid bag. Background Art

[0002] The double-attached tube of the waste liquid bag is mainly applied to hemodialysis and is a consumable for hemodialysis, mainly used for blood purification of patients with kidney function problems and is a necessity for patients during hemodialysis, so it is widely used clinically. At present, in the production of the double-attached tube of the waste liquid bag, most production processes are completed by workers with the assistance of some simple tooling, with a low degree of full automation, a high degree of dependence on workers, and a great influence of human factors on product quality. Moreover, there are still many problems in the following several assembly processes: First, when the anti-bacterial cap assembly is tightened and assembled, it needs to be manually tightened by workers, and the force needs to be controlled; second, when the mother needle base and the tee joint assembly are adhesively assembled, workers need to manually apply cyclohexanone glue on the catheter first, and then the mother needle base or the tee joint assembly can be installed. In this method, the assembly of workers has a relatively large impact on the product appearance, with poor consistency, and cyclohexanone has an odor, which will harm the physical and mental health of workers.

[0003] The patent with the publication number of "CN206966990U" discloses an "assembly mechanism for a stop flow clamp and a catheter". However, this device can only perform the assembly of the stop flow clamp.

[0004] The patent with the publication number of "CN106041445A" discloses a "mother needle base cover assembly device", which can only perform the assembly of the mother needle base and has a low degree of automation.

[0027] The drawings are only for illustrative purposes and should not be construed as a limitation of this patent; for better illustration of this embodiment, some components in the drawings may be omitted, enlarged or reduced, and do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. Detailed implementation manners

[0028] The present invention will be further described below with reference to the drawings. Embodiment

[0029] As Figure 1 shown, it is a schematic diagram of the finished product structure of the waste liquid bag with double attached tubes produced in this embodiment. The attached tubes include two conduit tubes 1801, stop flow clamps 1802 are installed on both of the two conduit tubes 1801, the ends of the two conduit tubes 1801 are connected by a tee 1805, female needle bases 1803 are installed at the front ends of the two conduit tubes 1801, and an antibacterial cap 1804 is installed on one of the female needle bases 1803.

[0030] Its assembly process is mainly carried out in two steps, asFigure 2 and Figure 3 As shown in Figure 3 , the first step is as follows: Install a stop clamp 1802 on the catheter 1801, then install a female needle base 1803 at its front end, and screw on an anti-bacterial cap 1804 on the female needle base 1803 (for the female needle base 1803 without the anti-bacterial cap 1804 screwed on, during the process of screwing on the anti-bacterial cap 1804, there is no need to set up a screwing device for the anti-bacterial cap, or make the screwing device of the anti-bacterial cap run idly so that the anti-bacterial cap material box is an empty box); The second step is: Group the catheters 1801 without the anti-bacterial cap 1804 screwed on and the catheters 1801 with the anti-bacterial cap 1804 screwed on in pairs, and then install a tee 1805.

[0031] Before the submission of this application, an affiliated enterprise of the applicant submitted a prior application "Application No. 2024119099690, Name: An Assembly Device for an Accessory Tube of an Extracorporeal Circulation Blood Path", which has disclosed an assembly device for assembling an accessory tube of an extracorporeal circulation blood path by installing a stop clamp 1802, a female needle base 1803, and an anti-bacterial cap 1804 on the catheter 1801. The finished product of this accessory tube is the same as the product completed in the first step of this application. Therefore, in this embodiment, the assembly process of the second step will be mainly explained.

[0032] As Figure 15 、 Figure 16 and Figure 17 As shown in Figure 15 , Figure 16 , and Figure 17 , an assembly device for a double accessory tube of a waste liquid bag includes a desktop 17. A single-tube chain conveyor 16 and a double-tube chain conveyor 15 for conveying the catheter 1801 are arranged on the desktop 17. In the moving direction of the single-tube chain conveyor 16, a catheter loading device 1, a stop clamp loading and assembling device 2, a stop clamp detection device 3, a single-tube gluing device 4, a female needle base loading and assembling device 5, an anti-bacterial cap tightening device 6, a first vision detection device 7, and a defective product discharging device 8 are sequentially arranged. In the moving direction of the double-tube chain conveyor 15, a pitch-changing device 10, a double-tube gluing device 11, a tee loading and assembling device 12, a second vision detection device 13, and a finished product discharging device 14 are sequentially arranged; Among them, the movement of the catheter 1801 from the catheter loading device 1 to the anti-bacterial cap tightening device 6 is mainly the content of the aforementioned first step, which will not be elaborated in this embodiment. It will be described starting from the first vision detection device 7.

[0033] As Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , in this embodiment, the single-tube chain conveyor 16 conveys 8 catheters 1801 at a time. In contrast, the double-tube chain conveyor 15 conveys 4 groups of catheters 1801 at a time. In some embodiments, the number of catheters 1801 conveyed at a time can vary.

[0034] A transfer device 9 for moving the conduit 1801 from the single-tube chain conveyor 16 to the double-tube chain conveyor 15 is also provided on the desktop 17.

[0035] In this embodiment, for the convenience of description, in the horizontal direction, the conveying directions of the single-tube chain conveyor 16 and the double-tube chain conveyor 15 are defined as left and right, and the direction perpendicular to them is defined as front and back; the movement in the vertical direction is defined as up and down.

[0036] As Figure 4 shown, the first vision detection device 7 includes a first camera 707 for taking pictures, and the first camera 707 is connected to a first detection station servo motor 703 that controls its left and right movement.

[0037] The first vision detection device 7 further includes a first detection station pipe clamping fixture 714 for clamping the conduit 1801. The first detection station pipe clamping fixture 714 is connected to a first detection station pipe clamping telescopic rod 717 that controls its clamping action. The first detection station pipe clamping telescopic rod 717 is arranged on a first detection station first cross plate 715, and a first detection station material pulling telescopic rod 716 for driving its front and back movement is also arranged on the first detection station first cross plate 715; The first vision detection device 7 further includes a V-shaped plate 712 for restricting the displacement of the stop clamp 1802 and a first detection station lowering telescopic rod 706. A first detection station pressing block 710 for pressing the conduit 1801 is further arranged at the lower part of the first detection station lowering telescopic rod 706. The first detection station pipe clamping telescopic rod 717, the first detection station material pulling telescopic rod 716, and the first detection station lowering telescopic rod 706 are all air cylinders.

[0038] The first bottom plate 701 of the first detection station and the second bottom plate 718 of the first detection station are arranged on the table 17. A first detection station support plate 719 is arranged on the second bottom plate 718 of the first detection station. A first detection station intermediate connecting plate 721 is arranged on the first detection station support plate 719. A first detection station material pulling telescopic rod 716 is arranged on the first detection station intermediate connecting plate 721. The first cross plate 715 of the first detection station is fixed on the first detection station intermediate connecting plate 721 through a guide rail. The first detection station profile bracket 702 is fixed on the first bottom plate 701 of the first detection station. A first detection station single-axis driver 704 and a first detection station lifting cylinder 720 are installed on the first detection station profile bracket 702. A first detection station back plate 705 is installed on the first detection station single-axis driver 704. The first detection station single-axis driver 704 is connected to the first detection station servo motor 703 through a coupling. A first detection station descending telescopic rod 706 is installed on the first detection station back plate 705. The first vision detection device 7 further includes a first detection station light source structure 713 for supplementary lighting. A first detection station product support plate 711 and a V-shaped plate 712 are installed on the first detection station light source structure 713.

[0039] When the single-tube chain conveyor 16 brings the conduit 1801 to this station, the first detection station lifting cylinder 720 operates to drive the V-shaped plate 712 to move to the designated position to position the conduit 1801 and the stop clamp 1802. Then, the first detection station material pulling telescopic rod 716 pushes the first horizontal plate 715 of the first detection station forward, and the first detection station pipe clamping telescopic rod 717 operates to make the first detection station pipe clamping fixture 714 clamp the conduit 1801. Then, the first detection station lowering telescopic rod 706 moves downward to make the first detection station pressing block 710 press the conduit 1801 (press the end of the crimping female pin base 1803, and press the conduit 1801 to the position where it contacts the product support plate 711 of the first detection station. The force is controlled by the spring force, about 2N. The crimping is to control the height of the conduit 1801 at the same position for visual inspection and improve the detection pass rate). Then, the first detection station servo motor 703 drives the first camera 707 to move left (or right), sequentially photograph the conduit 1801, and then output the detection result to the PLC controller to facilitate removing the unqualified products in the unqualified material discharging device 8. Then, the first detection station material pulling telescopic rod 716 retracts backward, moving the first horizontal plate 715 of the first detection station and the conduit 1801 clamped by the first detection station pipe clamping fixture 714 backward to the designated position, pulling the conduit 1801 by a specified length to meet the process requirements of the subsequent stations (the elongation is for the subsequent sorting station. After the elongation standard exceeds the set distance, the products can be flush after sorting. That is, align the ends of the conduit 1801, and the stop clamps 1802 installed thereon are also aligned. After the stop clamp 1802 is blocked by the V-shaped plate 712, at this time the stop clamp 1802 is aligned, and then pull the conduit 1801 until the conduit 1801 is aligned. Since the first detection station pipe clamping fixture 714 does not clamp the conduit 1801 tightly, at the alignment position of the conduit 1801, the first detection station pipe clamping fixture 714 cannot continue to pull the conduit 1801 to move). Finally, all actions are reset to complete the detection function of this station.

[0040] As Figure 5 shown, the unqualified material discharging device 8 includes an unqualified fixture 804 for clamping the unqualified conduit 1801. The unqualified fixture 804 is connected to the unqualified material discharging station lowering telescopic rod 811 that controls its up and down movement and the unqualified material discharging station synchronous belt mechanism 808 that controls its front and back movement.

[0041] The first bottom plate 801 and the second bottom plate 802 of the unqualified blanking station are installed on the table 17, on which the profile bracket 803 of the unqualified blanking station is installed. The synchronous belt mechanism 808 of the unqualified blanking station is installed on the profile bracket 803 of the unqualified blanking station. The servo motor 813 of the unqualified blanking station is fixed on the reducer 814, and is connected to the synchronous belt mechanism 808 of the unqualified blanking station through the coupling 815 of the unqualified blanking station to form a mechanism for transporting products. The unqualified fixture 804 is fixed on the pneumatic gripper 805 of the unqualified blanking station. There are 8 sets of the unqualified fixture 804 and the pneumatic gripper 805 of the unqualified blanking station, respectively corresponding to the 8 ducts transported each time in this embodiment. The pneumatic gripper 805 of the unqualified blanking station is fixed on the first cross plate 806 of the unqualified blanking station. The first cross plate 806 of the unqualified blanking station is connected to the descending telescopic rod 811 of the unqualified blanking station and can move through the guide shaft 809 of the unqualified blanking station. The U-shaped fixing plate 810 of the unqualified blanking station connects 2 guide shafts 809 of the unqualified blanking station. The descending telescopic rod 811 of the unqualified blanking station is fixed on the second cross plate 812 of the unqualified blanking station. The second cross plate 812 of the unqualified blanking station is installed on the guide rail 807 of the unqualified blanking station and is connected to the synchronous belt mechanism 808 of the unqualified blanking station.

[0042] When the single-tube chain conveyor 16 brings the duct 1801 to this station, if the first vision inspection device 7 detects unqualified products in the previous step, the servo motor 813 of the unqualified blanking station drives the synchronous belt mechanism 808 of the unqualified blanking station to move, and then drives the second cross plate 812 of the unqualified blanking station, the descending telescopic rod 811 of the unqualified blanking station, the first cross plate 806 of the unqualified blanking station, the unqualified fixture 804, and the pneumatic gripper 805 of the unqualified blanking station to move to the material-taking position. After the descending telescopic rod 811 of the unqualified blanking station moves downward to the specified position, the pneumatic gripper 805 of the unqualified blanking station corresponding to the unqualified product acts to control the corresponding unqualified fixture 804 to clamp the unqualified product. Then, the descending telescopic rod 811 of the unqualified blanking station resets and returns. The servo motor 813 of the unqualified blanking station starts again, so that the unqualified fixture 804 and the pneumatic gripper 805 of the unqualified blanking station move to the unqualified area position, and the unqualified fixture 804 resets and releases the product, and places the product in the unqualified area, completing the unqualified blanking function of this station. If the first vision inspection device 7 does not detect unqualified products in the previous step, the components of this station do not move.

[0043] It should be noted that in this embodiment, for the 8 ducts 1801 transported each time, during the transportation process, along the transportation direction, they are numbered as: 1, 2, 3, 4, 5, 6, 7, 8 respectively. Such as Figure 2 and Figure 3As shown, after being moved from the single-tube chain conveyor 16 to the double-tube chain conveyor 15, the ducts 1801 numbered 1, 3, 5, and 7 (without the anti-bacterial caps 1804) need to be moved to the ducts 1801 numbered 2, 4, 6, and 8 (with the anti-bacterial caps 1804) respectively to form pairs. Then, at the first visual inspection device 7, once the duct 1801 numbered 1 is found to be unqualified, regardless of whether the duct 1801 numbered 2 that cooperates with it is qualified or not, it must also be marked as unqualified to ensure that at the unqualified blanking device 8, both ducts 1801 are placed in the unqualified area position.

[0044] As Figure 6 shown, the transfer device 9 includes a transfer mechanism 903 for temporarily storing the ducts 1801, a material-taking and clamping mechanism 907 for moving the ducts 1801 from the single-tube chain conveyor 16 to the transfer mechanism 903, and a material-releasing and clamping mechanism 905 for moving the ducts 1801 from the transfer mechanism 903 to the double-tube chain conveyor 15; Both the material-taking and clamping mechanism 907 and the material-releasing and clamping mechanism 905 are connected to a transfer station descending telescopic rod 910 that controls their up and down movement and a transfer station synchronous belt mechanism 909 that controls their front and back movement.

[0045] The first transfer station bottom plate 901, the second transfer station bottom plate 902, and the third transfer station bottom plate 904 are all fixed on the table 17, on which a transfer station profile bracket 908 is provided. The transfer mechanism 903 is installed on the second transfer station bottom plate 902. The transfer station moving cross plate 906 is connected to the transfer station synchronous belt mechanism 909 and is installed on the transfer station profile bracket 908 through a guide rail. The material-taking and clamping mechanism 907, the material-releasing and clamping mechanism 905, and the transfer station descending telescopic rod 910 are also installed on the transfer station moving cross plate 906. The transfer station synchronous belt mechanism 909 is connected to the transfer station servo motor 912 through a transfer station coupling 914.

[0046] When the single-tube chain conveyor 16 brings the product to this station, the transfer station servo motor 912 operates. After the transfer station synchronous belt mechanism 909 drives the transfer station moving cross plate 906 to the material-taking position, the transfer station descending telescopic rod 910 moves down. The material-taking and clamping mechanism 907 clamps the product of the single-tube chain conveyor 16, and the material-releasing and clamping mechanism 905 clamps the product stored on the transfer mechanism 903 (placed by the material-taking and clamping mechanism 907 during the previous operation). Then, the transfer station descending telescopic rod 910 moves up, the transfer station moving cross plate 906 moves to the material-releasing position, the transfer station descending telescopic rod 910 moves down, the material-taking and clamping mechanism 907 releases the clamped product and places it on the transfer mechanism 903, the material-releasing and clamping mechanism 905 releases the clamped product and places it on the double-tube chain conveyor 15. Finally, all actions are reset to transfer the product from the single-tube chain conveyor 16 to the double-tube chain conveyor 15.

[0047] As Figure 7 shown, the pitch-changing device 10 includes a pitch-changing station clamping mechanism for clamping the catheter 1801 and a material-pushing mechanism 1013 for pushing aside the catheter 1801. The pitch-changing station clamping mechanism is installed on a pitch-changing station lowering air cylinder 1009 that can move left and right.

[0048] The pitch-changing station bottom plate 1001 is fixed on the table 17, and the pitch-changing station cross plate 1006 is fixed on the pitch-changing station bottom plate 1001 through two pitch-changing station support plates 1002; a pitch-changing station servo motor 1008 and a pitch-changing station single-axis driver 1007 are arranged on the pitch-changing station cross plate 1006, and a pitch-changing station lowering air cylinder 1009 is installed on the pitch-changing station single-axis driver 1007. When the pitch-changing station servo motor 1008 rotates, the pitch-changing station lowering air cylinder 1009 can reciprocate on the single-axis driver 1007. The pitch-changing station lowering air cylinder 1009 is further connected to a pitch-changing station first intermediate connection plate 1010 driven by it. A pitch-changing station left clamping air cylinder 1011 and a pitch-changing station right clamping air cylinder 1005 are arranged on the pitch-changing station first intermediate connection plate 1010, and they are respectively connected to a pitch-changing station left clamping mechanism 1012 and a pitch-changing station right clamping mechanism 1004. The pitch-changing station left clamping mechanism 1012 and the pitch-changing station right clamping mechanism 1004 form the aforementioned pitch-changing station clamping mechanism. A pitch-changing station rising air cylinder 1016 is further arranged on the pitch-changing station support plate 1002. The pitch-changing station rising air cylinder 1016 is connected to a material-pushing air cylinder 1014 through a pitch-changing station second intermediate connection plate 1015, and a material-pushing mechanism 1013 is installed on the material-pushing air cylinder 1014.

[0049] When the double-tube chain conveyor 15 brings the product to this station, the variable pitch station lifting cylinder 1016 drives the material pushing cylinder 1014 and the material pushing mechanism 1013 to move down to the designated position. The material pushing cylinder 1014 drives the material pushing mechanism 1013 to move left to push aside the 4 conduits 1801 with the anti-bacterial caps 1804 installed (by default, no unqualified products are found in the previous process. If there are unqualified products, there may be 3 / 2 / 1 / 0. Since the unqualified rate is relatively low, if there are unqualified products, during the operation of the material pushing mechanism 1013, it is equivalent to idling, that is, there is no corresponding conduit 1801 at the material pushing mechanism 1013). The material pushing mechanism 1013 corresponds one-to-one with the 4 conduits 1801 with the anti-bacterial caps 1804 installed, and pushes them aside respectively to place them into the 4 conduits 1801 without the anti-bacterial caps 1804 installed. Then the variable pitch station servo motor 1008 rotates, causing the variable pitch station lowering cylinder 1009 to move right to the material taking position. After that, the variable pitch station lowering cylinder 1009 extends to drive the left clamping mechanism 1012 and the right clamping mechanism 1004 of the variable pitch station to move down and clamp the 4 conduits 1801 without the anti-bacterial caps 1804 installed. Then, the variable pitch station lowering cylinder 1009 retracts and resets, and moves left to the material discharging position. The variable pitch station lowering cylinder 1009 extends, and the left clamping mechanism 1012 and the right clamping mechanism 1004 of the variable pitch station place the 4 conduits 1801 without the anti-bacterial caps 1804 clamped on one side of the 4 conduits 1801 with the anti-bacterial caps 1804 installed, making them in pairs (it should be noted here that if the product spacing is small and the left clamping mechanism 1012 and the right clamping mechanism 1004 of the variable pitch station release the conduits 1801 at the same time, which may cause component interference, one clamping mechanism can be released first and then the other to avoid interference). Finally, all actions are reset to complete the variable pitch transfer of the product.

[0050] As Figure 8 and Figure 9 shown, the double-tube glue coating device 11 includes an upper V-shaped clamp 1107 and a lower V-shaped clamp 1108 for clamping the conduit 1801, a first glue box 1104 for containing glue, and a glue coating clamp 1111 for taking glue from the first glue box 1104 and coating the conduit 1801. The glue coating clamp 1111 is connected with a glue coating jaw cylinder 1112 for controlling its opening and closing, a glue taking telescopic rod 1116 for controlling its glue taking, and a glue coating telescopic rod 1118 for controlling its glue coating.

[0051] The glue coating station bottom plate 1101 is installed on the table 17. Two first vertical plates 1102 and two second vertical plates 1103 of the glue coating station are installed on the glue coating station bottom plate 1101. A first cross plate 1105 and a second cross plate 1110 of the glue coating station are installed on the two first vertical plates 1102 of the glue coating station. A third cross plate 1122 and the first glue box 1104 of the glue coating station are installed on the two second vertical plates 1103 of the glue coating station.

[0052] On the first horizontal plate 1105 of the glue application station, a clamping cylinder 1106 for the upper pipe at the glue application station is installed. On the clamping cylinder 1106 for the upper pipe at the glue application station, an upper V-shaped fixture 1107 is installed. On the second horizontal plate 1110 of the glue application station, a clamping cylinder 1109 for the lower pipe at the glue application station is installed. On the clamping cylinder 1109 for the lower pipe at the glue application station, a lower V-shaped fixture 1108 is installed.

[0053] On the third horizontal plate 1122 of the glue application station, a glue application telescopic rod 1118 and a guide shaft 1117 at the glue application station are installed. At the ends of both, a connecting block 1120 at the glue application station is installed. The connecting block 1120 at the glue application station is connected to the glue taking telescopic rod 1116 through two support columns 1115 at the glue application station. The connecting block 1120 at the glue application station is also connected to two support plates 1121 at the glue application station through a support shaft 1119 at the glue application station. The two support plates 1121 at the glue application station are connected to a back plate 1113 at the glue application station. On the back plate 1113 at the glue application station, a clamping jaw cylinder 1112 for the glue application is installed. The clamping jaw cylinder 1112 for the glue application is connected to a glue application fixture 1111. The back plate 1113 at the glue application station is also connected to the glue taking telescopic rod 1116 through a fixing block 1114 at the glue application station.

[0054] When the double-pipe chain conveying device 15 brings the product to this station, the clamping cylinder 1106 for the upper pipe at the glue application station and the clamping cylinder 1109 for the lower pipe at the glue application station move relatively, so that the upper V-shaped fixture 1107 and the lower V-shaped fixture 1108 clamp the conduit 1801. Then the glue taking telescopic rod 1116 extends downward, so that the glue application fixture 1111 dips downward into the first glue box 1104. Then the glue taking telescopic rod 1116 resets to make the glue application fixture 1111 after dipping in the glue break away from the first glue box 1104. (Among them, the clamping jaw cylinder 1112 for the glue application, the glue application fixture 1111, the back plate 1113 at the glue application station, the fixing block 1114 at the glue application station, and the two support plates 1121 at the glue application station act as a whole. There is a ball bearing between the glue taking telescopic rod 1116 and the fixing block 1114 at the glue application station, which can realize rotation. There is a ball bearing between the two support plates 1121 at the glue application station and the support shaft 1119 at the glue application station, which can realize rotation. When the glue taking telescopic rod 1116 extends, the aforementioned device swings downward as a whole, so that the glue application fixture 1111 can take the glue). Then the glue application fixture 1111 opens under the action of the clamping jaw cylinder 1112 for the glue application (to facilitate the insertion of the conduit 1801). The glue application telescopic rod 1118 extends to make the glue application fixture 1111 sleeved on the outside of the conduit 1801. Then the clamping jaw cylinder 1112 for the glue application controls the glue application fixture 1111 to close, and applies the glue it has dipped on the conduit 1801. Finally, the glue application telescopic rod 1118 retracts to reset, completing the double-pipe glue application function.

[0060] On the three-way station fixing plate 1235, a three-way station intermediate connecting plate 1229 and a three-way station synchronous belt mechanism 1216 are installed. On the three-way station intermediate connecting plate 1229, a three-way station assembly jaw 1228 is installed.

[0061] When the double-tube chain conveyor 15 brings the product to this station, the pipe clamping fixture 1218 at the three-way station and the pipe clamping fixture 1219 under the three-way station clamp the conduit 1801; the material taking cylinder 1212 at the three-way station moves downward to the specified position, and the material taking fixture 1207 at the three-way station clamps the three-way joint 1805 from within the material channel mechanism 1206 at the three-way station; then the material taking cylinder 1212 at the three-way station moves upward to reset, and the translation cylinder 1208 at the three-way station drives the second horizontal plate 1210 at the three-way station and the material taking cylinder 1212 at the three-way station to translate to the specified position. The material taking cylinder 1212 at the three-way station moves downward, and the material taking fixture 1207 at the three-way station places the three-way joint 1805 on the moving material channel 1233 at the three-way station; then the material moving cylinder 1234 operates to move the three-way joint 1805 to the specified position; at this time, the servo motor 1213 at the three-way station drives the fifth horizontal plate 1230 at the three-way station to move to the material taking position, and the lifting cylinder 1232 at the three-way station moves downward to the specified position. The assembly fixture 1227 at the three-way station clamps the three-way joint 1805 on the moving material channel 1233 at the three-way station, and then the lifting cylinder 1232 at the three-way station moves upward to reset; at the same time, the rotary cylinder 1226 rotates to the specified position to immerse the glue coating profiling structure 1225 into the second glue box 1222, and then the rotary cylinder 1226 resets. The glue ejecting cylinder 1223 moves upward to lift the glue coating profiling structure 1225. The servo motor 1213 at the three-way station drives the assembly fixture 1227 at the three-way station to move, so that the clamped three-way joint 1805 is inserted onto the glue coating profiling structure 1225 and stays for 0.2 seconds to coat the inner wall of the three-way joint 1805 with glue; then the servo motor 1213 at the three-way station drives the glue-coated three-way joint 1805 to retreat to the specified position, and the glue ejecting cylinder 1223 moves downward to reset; the servo motor 1213 at the three-way station drives the assembly fixture 1227 at the three-way station to move again to assemble the glue-coated three-way joint 1805 onto the clamped conduit 1801. Finally, all actions start to reset to the initial state, completing the feeding and assembly functions of the three-way joint 1805.

The second camera 1305 is arranged on the second inspection station single-axis driver 1304, and the second inspection station single-axis driver 1304 is connected to the second inspection station servo motor 1303.

[0064] When the double-tube chain conveying device 15 brings the product to this station, the second inspection station lifting cylinder 1306 moves upward to make the second inspection station V-shaped fixture 1307 move upward. During this process, the conduit 1801 on the double-tube chain conveying device 15 will fall into the second inspection station V-shaped fixture 1307 for fixation. Then the second inspection station servo motor 1303 drives the second camera 1305 to move to take pictures of the conduit 1801 in sequence, and then outputs the inspection result to the PLC controller. Finally, all actions are reset to complete the three-way vision inspection function of this station.
