[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Directional terms used herein, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," and "side," refer only to directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention. Furthermore, in the accompanying drawings, similar or identical structures are denoted by the same reference numerals.

[0036] See also Figure 1 , Figure 1 This is a schematic diagram of a paired packaging device for air conditioner connecting pipes and drain pipes, according to one embodiment of the present invention. This paired packaging device is used for packaging drain pipes and connecting pipes for air conditioners. The paired packaging device includes a connecting pipe conveying mechanism 4, a connecting pipe storage mechanism 3, a drain pipe storage mechanism 1, a drain pipe conveying mechanism 2, a drain pipe grabbing mechanism 5, a detection mechanism 6, and a packaging mechanism 7. The structure and operating principle of this paired packaging device are described in detail below, with reference to the accompanying drawings.

[0037] In order to make the embodiment clear and complete, the following description is made by separating the drainage pipe side and the connecting pipe side. First, the structure and working principle of the drainage pipe side are described in detail below with reference to the accompanying drawings.

[0038] Reference Figure 2 First, the structure of the drain pipe storage mechanism 1 of this embodiment is described. The drain pipe storage mechanism 1 includes a first belt 11, two first side baffles 12, two push plates 13 and two first driving members 14 that respectively drive the two push plates 13. The two first side baffles 12 are respectively arranged on both sides of the first belt 11. The two first side baffles 12 and the ends of the first belt 11 define a drain pipe discharge port 19, and the two push plates 13 are respectively rotatably connected to the two first side baffles 12; wherein, the two first driving members 14 respectively push the two push plates 13 toward the first belt 11 to rotate to narrow the drain pipe discharge port 19.

[0039] Specifically, the first belt 11 comprises two sections: a flat section and a sloped section. The flat section forms the starting point of the first belt 11, while the sloped section forms the end point. The sloped section ends at the drain pipe outlet 19. The first belt 11 transports the drain pipe upward from the flat section to the sloped section, where it is discharged from the drain pipe outlet 19. Two first side baffles 12 are installed on either side of the entire first belt 11. A baffle is also installed on one side of the flat section. This baffle is connected to the two first side baffles 12 and, together with the two first side baffles 12, forms a silo structure into which the drain pipe is manually coiled and stacked. The purpose of designing the first belt 11 into a two-section structure, consisting of a flat section and a sloped section, is to increase the depth of the silo to accommodate more drain pipes. The push plate 13 is in the shape of a right triangle as a whole. The hypotenuse of the push plate 13 is inclined along the slope section. One right-angled side of the push plate 13 is flush with the upper edge of the first side baffle 12. The other right-angled side of the push plate 13 is connected to the inner side of the first side baffle 12 via a folded edge, and the folded edge is perpendicular to the flat section. The push plate 13 is connected to the inner side of the first side baffle 12 via a connecting buckle 131, so that the push plate 13 can rotate. The first driving member 14 is a cylinder. Both cylinders are installed on the outside of the first side baffle 12. The push rods of the two cylinders pass through the first side baffles 12 on both sides and are connected to the two push plates on the inside. When the cylinders on both sides are in action, the push rods push the two push plates 13 to rotate, and the two push plates 13 move relative to each other, thereby reducing the discharge port 19 of the drain pipe, thereby reducing the amount of drainage pipe conveying. That is, when the number of drain pipes conveyed is too large, the number of drain pipes conveyed is reduced by controlling the first driving member 14 to push the pushing plate 13 to shrink the drain pipe outlet 19 .

[0040] Furthermore, the drainage pipe storage mechanism 1 also includes two support rods, a material limiting baffle 16, a baffle bracket 17 and a material pushing detection switch 18. The two support rods are respectively connected to the two first side baffles 12, and the two support rods are horizontally spaced apart. The material limiting baffle 16 is rotatably connected to one of the support rods. The baffle bracket 17 includes a support section 171 and an extension section 172. The support section 171 is overlapped on the two support rods, and one end of the extension section 172 is connected to the support section 171, and the other end of the extension section 172 extends toward the direction of the first belt 11 and is connected to the material limiting baffle 16; wherein, the material pushing detection switch 18 is installed on the baffle bracket 17 to trigger and control the first driving member 14 when the material limiting baffle 16 rotates.

[0041] Specifically, the two support rods are a first support rod 151 and a second support rod 152. Both ends of the first support rod 151 and the second support rod 152 are connected to the two first side baffles 12. That is, the first support rod 151 and the second support rod 152 are horizontal between the two first side baffles 12. The first support rod 151 and the second support rod 152 are both arranged above the slope section. The first support rod 151 and the second support rod 152 are on the same horizontal plane and are spaced apart. The second support rod 152 is closer to the drain pipe outlet 19 than the first support rod 151. The material limit baffle 16 is connected to the rotating shaft of the first support rod 151 so that the material limit baffle 16 can rotate around the first support rod 151 as the axis. The length of the material limit baffle 16 is greater than the distance between the first support rod 151 and the second support rod 152. Therefore, when the material limit baffle 16 rotates upward, it is stopped by the second support rod 152 and cannot continue to rotate upward. The baffle bracket 17 is specifically a bracket made of aluminum profile, which has a segmented structure. One end is a support section 171, and the other end is an extension section 172. The support section 171 is perpendicular to the first support rod 151 and the second support rod 152 (that is, the axial direction of the support section 171 is the same as the conveying direction of the first belt 11). The support section 171 rests on the first support rod 151 and the second support rod 152. The end of the support section 171 near the drain pipe outlet 19 passes over the second support rod 152 and is connected to the extension section 172. The extension section 172 specifically extends a short distance toward the slope section of the first belt 11. Then, by connecting the extension section 172 to the material limit baffle 16, the material limit baffle 16 can be pulled up and supported. Due to the existence of the extension section 172, there is a certain height difference between the material limit baffle 16 and the second support rod 152. In this way, the material limit baffle 16 can continue to rotate upward for a certain distance, but will not exceed this height difference because it will be stopped by the second support rod 152. The lower edge of the limiting baffle 16 is at a certain height from the sloped section, allowing drainage pipes to pass through. A push detection switch 18 is mounted on the baffle bracket 17, specifically located on the extension section 172. It detects the upward rotation of the limiting baffle. During operation, because a large number of drainage pipes are manually placed into the silo in a disorganized manner, the pipes overlap and intertwine during transportation. When the pipes are stacked too high, the limiting baffle 16 is lifted during transportation, causing it to rotate upward, thereby triggering the push detection switch 18. In other words, when the number of drain pipes being transported is too large, the pipes will stack too high, pushing up the limiting baffle 16 and triggering the push detection switch 18. This in turn controls the first drive member 14 to rotate the push plate 13, narrowing the drain pipe outlet 19 and thereby reducing the number of drain pipes being transported. In other words, the cooperation between the limiting baffle 16 and the push plate 13 automatically adjusts the size of the drain pipe outlet 19, achieving flow control and effective, stable transportation of the drain pipes.

[0042] Reference Figure 3Next, the structure of the drainage pipe conveying mechanism 2 of this embodiment is described. The drainage pipe conveying mechanism 2 includes a second belt 21, two second side baffles 22, and at least one diverter baffle 23. The two second side baffles 22 are respectively arranged on both sides of the second belt 21. The diverter baffle 23 is connected to the second side baffles 22 and is suspended relative to the second belt 21; wherein the height of the lower edge of the diverter baffle 23 from the second belt 21 is the same as the height of one of the drainage pipes.

[0043] First, it should be noted that in this embodiment, two drain pipe conveying mechanisms 2 are provided: a sloped section drain pipe conveying mechanism 2 and a flat section drain pipe conveying mechanism 2. The sloped section drain pipe conveying mechanism 2 and the flat section drain pipe conveying mechanism 2 have identical structures, differing in that the second belt 21 of the sloped section drain pipe conveying mechanism 2 is inclined, while the second belt 21 of the flat section drain pipe conveying mechanism 2 is horizontal. The sloped section drain pipe conveying mechanism 2 is connected to the drain pipe storage mechanism 1, while one end of the flat section drain pipe conveying mechanism 2 is connected to the sloped section drain pipe conveying mechanism 2 and the other end is connected to the connecting pipe conveying mechanism 4.

[0044] For the sloped section drainage pipe conveying mechanism 2, the inclination gradient of the second belt 21 is the same as the inclination gradient of the sloped section of the first belt 11, so that the two can be seamlessly connected. Two second side baffles 22 are also installed on both sides of the second belt 21. There are multiple diverter baffles 23. The diverter baffles 23 can be set only on the second side baffle 22 on one side, or on the second side baffles 22 on both sides. For example, multiple diverter baffles 23 are alternately set on the second side baffles 22 on both sides. Among them, the diverter baffle 23 is in the shape of a rectangle, with the short side of one side connected to the inner side of the second side baffle 22, and the short side of the other side offset toward the second belt 21. It should be noted that the lower long side of the rectangle is at a certain distance from the surface of the second belt 21, so that the diverter baffle 23 is suspended relative to the second belt 21. As can be seen, the entire main body of the diverter baffle 23 is offset above the second belt 21, with the lower edge of the diverter baffle 23 spaced a certain distance from the surface of the second belt 21. This distance is exactly equal to or slightly greater than the height of a drain pipe behind the coil, allowing only one drain pipe to pass through. In this way, when overlapping drain pipes are transported, the upper pipe will be stopped by the diverter baffle 23, while the lower pipe will pass smoothly. This effectively limits the overlapping drain pipes and ensures smooth transportation of the drain pipe close to the belt.

[0045] Due to the plasticity of the drain pipe, there may still be overlap when the water is transported through the diversion baffle 23 by squeezing the drain pipe. Therefore, in order to further improve the blocking effect, an anti-blocking device is provided to ensure the final single transport.

[0046] Reference Figure 4 In this embodiment, the drainage pipe conveying mechanism 2 also includes an anti-blocking component 24, which includes a bracket column 241, a bracket plate 242, a spring 244 fixing plate 243, a spring 244 and a material limiting movable rod 245. The bracket column 241 is connected to the two second side baffles 22, the bracket plate 242 is installed on the bracket column 241, the spring 244 fixing plate 243 is installed on the bracket plate 242, one end of the material limiting movable rod 245 is rotatably connected to the bracket column 241, and the other end of the material limiting movable rod 245 extends toward the direction of the second belt 21, one end of the spring 244 is connected to the material limiting movable rod 245, and the other end of the spring 244 is connected to the spring 244 fixing plate 243.

[0047] Specifically, the ends of the support column 241 are mounted on the two second side baffles 22 via two side plate brackets 221. The side plate brackets 221 protrude from the second side baffles 22 to increase the installation height of the support column 241. One end of the material limiting movable rod 245 is sleeved on the support column 241, allowing the material limiting movable rod 245 to rotate about the support column 241 as the axis. The support plate 242 is shaped like a "concave" rectangular plate. One side with a notch is connected to the support column 241. The middle notch corresponds to the position where the material limiting movable rod 245 and the support column 241 are connected to form a gap. The spring 244 fixing plate 243 is also installed through the notch. The spring 244 fixing plate 243 passes through the notch and is installed against the surface of the spring 244 fixing plate 243. One end of the spring 244 is connected to the material limiting movable rod 245, and the other end of the spring 244 is fixed to the spring 244 fixing plate 243. The other end of the material limiting movable rod 245, that is, the end away from the support column 241, is spaced a certain distance from the surface of the second belt 21. This distance is exactly equal to or slightly greater than the height of a drain pipe behind the coil, allowing only one drain pipe to pass through. Thus, when overlapping drain pipes are conveyed, the upper drain pipe is stopped by the material limiting movable rod 245, while the lower drain pipe passes smoothly, thereby limiting the position of the overlapping drain pipes and ensuring smooth conveyance of the drain pipes that are close to the belt. The drain pipe conveying mechanism 2 utilizes a coordinated design of multiple diverter baffles 23 and anti-blocking components 24 to achieve individual conveyance of overlapping and staggered drain pipes.

[0048] In addition, a first detection photoelectric sensor 81 and a second detection photoelectric sensor 82 are also provided on the second side baffle 22. The first detection photoelectric sensor 81 is provided on the second side baffle 22 corresponding to the connection between the second belt 21 and the first belt 11. The first detection photoelectric sensor 81 is used to detect whether the drain pipe is successfully transported to the second belt 21; the second detection photoelectric sensor 82 is provided on the second side baffle 22 corresponding to the connection with the belt of the flat section drain pipe conveying mechanism 2. The second detection photoelectric sensor 82 is used to detect whether the drain pipe is successfully transported to the belt of the flat section drain pipe conveying mechanism 2.

[0049] The flat section drainage pipe conveying mechanism 2 has the same specific structure as the slope section drainage pipe conveying mechanism 2, both of which use a combination of multiple diversion baffles 23 and anti-blocking components 24. For the sake of brevity, this description will not be repeated here. It should be noted that, as for the sensor part, the second side baffle 22 of the flat section drainage pipe conveying mechanism 2 is equipped with a third detection photoelectric sensor 83 and a fourth detection photoelectric sensor 84. The third detection photoelectric sensor 83 is set on the second side baffle 22 at the connection point with the belt of the slope section drainage pipe conveying mechanism 2. The third detection photoelectric sensor 83 is used to detect whether the drainage pipe has been successfully conveyed to the belt of the flat section drainage pipe conveying mechanism 2; the fourth detection photoelectric sensor 84 is set on the second side baffle 22 at the connection point with the third belt 41 of the connecting pipe conveying mechanism 4. The fourth detection photoelectric sensor 84 is used to stop the conveyance of the second belt 21, so that the drainage pipe stays at the connection point, which facilitates the drainage pipe grasping mechanism 5 to grasp the drainage pipe.

[0050] Next, after a clear and complete description of the structure on the drain pipe side, the structure on the connecting pipe side will be described below.

[0051] First, the entire connecting pipe side is arranged based on the connecting pipe conveying mechanism 4, and the connecting pipe storage mechanism 3, the drainage pipe grabbing mechanism 5, the detection mechanism 6 and the packaging mechanism 7 are all installed in sequence along the conveying direction of the third belt 41 of the connecting pipe conveying mechanism 4.

[0052] As for the connecting pipe storage mechanism 3, the connecting pipe storage mechanism 3 includes a storage box, the connecting pipes are manually neatly stacked and placed in the storage mechanism, a connecting pipe discharge port and a limiting structure for the connecting pipe discharge port are provided below the storage box, and the lowest connecting pipe is in direct contact with the third belt 41. After the third belt 41 is started, the connecting pipe can only be transported out of the storage box one at a time through the limiting structure of the storage box discharge port under the drive of the third belt 41, thereby realizing the individual and one-by-one transportation of the connecting pipes. The design of the coordination between the storage box and the third belt 41 is adopted, and the individual and one-by-one transportation of the connecting pipes is realized through the drive of the third belt 41.

[0053] Reference Figure 5 In this embodiment, the connecting tube conveying mechanism 4 includes a third belt 41, a crossbeam support 42, a stopper mounting plate 43, and a stopper 44. The crossbeam support 42 straddles the third belt 41, the stopper mounting plate 43 is mounted on the crossbeam support 42, and the stopper 44 is mounted on the stopper mounting plate 43. The stopper 44 is configured to extend and retract toward the third belt 41. Specifically, the connecting tube storage mechanism 3 is located at the beginning of the third belt 41, and the connecting tubes discharged by the connecting tube storage mechanism 3 are conveyed by the third belt 41. However, because the discharge port of the storage box is designed to be larger than the outer shape of the connecting tubes, it is sometimes possible for the discharge port to discharge two stacked connecting tubes at once. To address this issue, in this embodiment, the crossbeam support 42 straddles the third belt 41, and a stopper mounting plate 43 is fixed in the middle of the crossbeam support 42 to accommodate the stopper 44. The stopper 44 can be a cylinder or other component with a telescopic function. The cylinder is suspended above the third belt 41, with its output shaft facing the belt. When extended, the cylinder's output shaft's height relative to the third belt 41 is precisely equal to the height of a connecting pipe, stopping any stacked connecting pipes. When the cylinder extends, if the connecting pipes are stacked, the cylinder restricts the passage of the upper connecting pipe while allowing the lower connecting pipe to pass freely, ensuring that the connecting pipes are transported individually.

[0054] It should be noted that in this embodiment, two sets of stops are provided on the third belt 41 to ensure that the connecting tubes are conveyed one by one. A fifth detection photoelectric sensor 85 is also provided on one side of the third belt 41. This fifth detection photoelectric sensor 85 is located in front of the crossbeam support 42. The fifth detection photoelectric sensor 85 is used to control the extension of the cylinder when it detects the conveyance of the connecting tube.

[0055] Reference Figure 6In this embodiment, the drain pipe grabbing mechanism 5 includes a mounting bracket 51, a transverse movement assembly 52, a lifting assembly 53, and a grabbing assembly 54. The mounting bracket 51 is mounted on the connecting pipe conveying mechanism 4 and the drain pipe conveying mechanism 2, the transverse movement assembly 52 is mounted on the mounting bracket 51, the lifting assembly 53 is mounted on the transverse movement assembly 52, and the grabbing assembly 54 is mounted on the lifting assembly 53. The grabbing assembly 54 grabs the drain pipe from the drain pipe conveying mechanism 2 and transfers it to the connecting pipe conveying mechanism 4 via the transverse movement assembly 52 and the lifting assembly 53. Specifically, the mounting bracket 51 is a rectangular frame with four legs, two of which are mounted on one side of the third belt 41 of the connecting pipe conveying mechanism 4, and the other two are mounted on both sides of the second belt 21 of the flat-section drain pipe conveying mechanism 2. The transverse movement component 52 is specifically a slide cylinder, and the lifting component 53 is a lifting cylinder. The slide rail of the slide cylinder spans the third belt 41 and the second belt 21 and is set at the top of the frame. The lifting cylinder is installed on the slide of the slide cylinder. In this way, the slide can drive the lifting cylinder to move between the third belt 41 and the second belt 21. The grabbing component 54 is installed at the output end of the lifting cylinder. When the lifting cylinder is extended, the grabbing component 54 descends to grab or place. When the lifting cylinder is retracted, the grabbing component 54 rises. The specific grabbing action is: the slide cylinder moves to the top of the second belt 21, the lifting cylinder extends, the grabbing component 54 descends to grab the drain pipe, the lifting cylinder retracts, the slide cylinder moves to the top of the third belt 41, the lifting cylinder extends again, and the drain pipe is placed in the inner ring of the connecting pipe. The lifting cylinder retracts, thereby completing the action of grabbing and placing the drain pipe. Through the cooperation of the transverse moving component 52, the lifting component 53 and the grabbing component 54, the connecting pipes of the drainage pipe are automatically matched, thereby avoiding the problem of missing installation caused by manual matching and improving the matching efficiency.

[0056] It should be noted that a sixth detection photoelectric sensor 86 is provided on one side of the third belt 41 below the mounting bracket 51. The sixth detection photoelectric sensor 86 is used to control the third belt 41 to stop conveying when it detects that the connecting pipe is being conveyed, so that the connecting pipe stays below the mounting bracket 51, which is convenient for pairing with the drain pipe.

[0057] Reference Figure 7 and Figure 8In a specific implementation, the grab assembly 54 includes a clamping claw mounting plate 543, a second driving member 544, a rotating shaft 547, a rotating block 548, a plurality of sliding assemblies 549 and a clamping claw 550. The clamping claw mounting plate 543 includes a first side surface and a second side surface opposite to each other; the first side surface is connected to the lifting assembly 53, the second driving member 544 is installed on the first side surface, the rotating shaft 547 is rotatably provided on the clamping claw mounting plate 543, and the second driving member 544 is connected to the rotating shaft 547 to drive the The rotating shaft 547 rotates; the rotating block 548 is arranged on the second side surface and is fixedly connected to the rotating shaft 547, and a plurality of sliding assemblies 549 are arranged on the second side surface around the rotating block 548, and the sliding assembly 549 includes a sliding end, and the clamping claw 550 is arranged on the sliding end, and the sliding end is transmission-connected to the rotating block 548; wherein, the rotating shaft 547 rotates through the rotating block 548 to drive the sliding end to slide so that the clamping claw 550 expands outward to clamp the inner ring of the drain pipe or contracts to loosen the drain pipe.

[0058] Specifically, the gripping assembly 54 also includes a disc mounting plate 541 and a connecting shaft 542. One side of the disc mounting plate 541 is fixed to the output end of the lifting cylinder, and the other side of the disc mounting plate 541 is connected to the clamping claw mounting plate 543 via the connecting shaft 542. As a result, due to the presence of the connecting shaft 542, an installation space is formed between the disc mounting plate 541 and the clamping claw mounting plate 543, so that the second driving member 544 can be arranged in this installation space. The side of the clamping claw mounting plate 543 facing the disc mounting plate 541 is a first side surface, and the other side of the clamping claw mounting plate 543 facing away from the disc mounting plate 541 is a second side surface. A through hole is defined in the middle of the disc mounting plate 541, which passes through the first side surface and the second side surface, and a rotating shaft 547 is rotatably disposed in this through hole. On the first side, the second driving member 544 is a cylinder, which is rotatably connected to one end of the rotating shaft 547 via a connecting rod 545 and a pin 546. Specifically, one end of the connecting rod 545 is mounted on the cylinder, and the other end is assembled on the rotating shaft 547 via the pin 546. When the cylinder is extended or retracted, the connecting rod 545 drives the rotating shaft 547 to rotate clockwise or counterclockwise. On the second side, the rotating block 548 is a triangular block. Three sliding assemblies 549 are arranged around the triangular block. The sliding assembly 549 includes a slide rail 5491 and a connecting plate 5492. The connecting plate 5492 can slide along the slide rail 5491 and the connecting plate 5492 is a sliding end. The clamping jaws 550 are connected to the connecting plate 5492. The three clamping jaws 550 are respectively connected to the three connecting plates 5492. The clamping jaws 550 are specifically short rods, which are maintained in a vertical position. Connecting plate 5492 is also rotatably connected to the triangular block via connecting rods 545, with the ends of the three connecting rods 545 connected to the three acute angles of the triangular block. Thus, when rotating shaft 547 rotates clockwise, connecting rods 545 push connecting plate 5492 away from rotating block 548, causing the three clamping jaws 550 to move away from each other, expanding them outward and thus clamping the inner ring of the drain pipe. When rotating shaft 547 rotates counterclockwise, connecting rods 545 pull connecting plate 5492 toward rotating block 548, causing the three clamping jaws 550 to move closer together and contract, thereby releasing the drain pipe and placing it within the inner ring of the connecting pipe, completing the automatic pairing.

[0059] Reference Figure 9As for the detection mechanism 6, the detection mechanism 6 is located after the drain pipe grasping mechanism 5. The detection mechanism 6 includes a detection camera 63, a camera mounting base 62 and a camera bracket 61. The camera is mounted on the camera mounting base 62, and the camera mounting base 62 is mounted on the camera bracket 61. The camera bracket 61 has four legs, and the four legs are respectively mounted on both sides of the third belt 41 in pairs. The camera is located above the third belt 41 and takes pictures of the paired drain pipe and connecting pipe in the direction of the third belt 41. The detection principle of the detection mechanism 6 is that the drain pipe and the connecting pipe are different colors, the drain pipe is white, and the connecting pipe is black. The color comparison of the image is used to determine whether there is a drain pipe in the connecting pipe. After the detection is completed, if the photo comparison does not match, the equipment will issue an alarm prompt. If the comparison matches, the paired connecting pipe will continue to be transported to the packaging mechanism 7 for the bagging and packaging process. The use of a camera to take pictures and compare the paired connecting pipe and drain pipe can achieve accurate and efficient detection of whether there are any deficiencies in the material.

[0060] As for the packaging mechanism 7, the packaging mechanism 7 is installed at the end of the third belt 41. It is the last process to seal and pack the matched connecting pipes and drainage pipes, thereby realizing full automation of the operation, automatic matching and packaging.

[0061] An embodiment of the present invention further provides a method for pairing and packaging an air conditioner connecting pipe and a drain pipe, which is applicable to the pairing and packaging device for the air conditioner connecting pipe and drain pipe described in the above embodiment. Since the pairing and packaging device has been described in detail above, it will not be repeated here for the sake of brevity. The method includes steps S1-S4.

[0062] S1, control the drainage pipe discharging mechanism to discharge the drainage pipe to the drainage pipe conveying mechanism 2, and control the connecting pipe storage mechanism 3 to discharge the connecting pipe to the connecting pipe conveying mechanism 4;

[0063] S2, controlling the drain pipe conveying mechanism 2 to convey the drain pipe to the drain pipe grabbing device, and controlling the connecting pipe conveying mechanism 4 to convey the connecting pipe to the drain pipe grabbing device;

[0064] S3, controlling the drainage pipe grabbing device to grab the drainage pipe and place it into the inner ring of the connecting pipe for pairing;

[0065] S4. Control the connecting pipe conveying mechanism 4 to convey the paired connecting pipe and the drain pipe to the packaging mechanism 7 for packaging.

[0066] For ease of understanding, the pairing packaging method of this embodiment is described below in conjunction with the entire process flow of pairing and packaging the connecting pipe and the drain pipe.

[0067] Before starting the machine, the drain pipe and connecting pipe are manually loaded into the drain pipe storage mechanism 1 and the connecting pipe storage mechanism 3, respectively. The connecting pipes are manually stacked and placed neatly in the storage box before being loaded. After loading is complete, the worker starts the machine. It should be noted that after starting the machine, the drain pipe and connecting pipe conveying operations are performed simultaneously. Ultimately, the two materials are paired at the drain pipe grabbing mechanism 5. The following process description will describe the conveying of the two materials separately.

[0068] Drain pipe side: First, for the sake of convenience, the second belt 21 of the sloped section drain pipe conveying mechanism 2 and the second belt 21 of the flat section drain pipe conveying mechanism 2 are distinguished, wherein the second belt 21 of the sloped section drain pipe conveying mechanism 2 is referred to as the second belt A21, and the second belt 21 of the flat section drain pipe conveying mechanism 2 is referred to as the second belt B21. The first belt 11 starts to operate to convey the drain pipe to the second belt A21. Since manually placing a large number of drain pipes into the drain pipe storage mechanism 1 is disorganized, the drain pipes will overlap and stagger when being conveyed in the storage mechanism. When the drain pipes are stacked too high, the material limit baffle 16 will be lifted during the conveying process, thereby triggering the push detection switch 18. At this time, the first drive member 14 will operate to push the push plate 13 out, thereby reducing the size of the drain pipe outlet 19, thereby reducing the number of drain pipes conveyed. When the drain pipe is transported to the second belt A21 and the first detection photoelectric sensor 81 detects a valid detection, the first belt 11 stops transporting. When the first detection photoelectric sensor 81 detects an invalid detection, the first belt 11 continues transporting. The drain pipe then continues to be transported by the second belt A21 to the second belt B21. When both the second detection photoelectric sensor 82 and the third detection photoelectric sensor 83 detect the presence of material, the second belt A21 stops transporting. Transporting continues until the third detection photoelectric sensor 83 detects no material, at which point the second belt A21 continues transporting. Finally, the drain pipe is transported by the second belt B21 to the fourth detection photoelectric sensor 84, where it stops. While the drain pipes are ultimately transported to the fourth detection photoelectric sensor 84, two or more drain pipes may overlap when transported from the first belt 11 to the second belt A21. Therefore, during transport, the drain pipes pass through multiple diversion baffles 23 and anti-blocking components 24 to ensure that a single drain pipe is transported to the fourth detection photoelectric sensor 84. The specific principle of the diverter baffle 23 here is: when the drain pipe is placed in the drain pipe storage mechanism 1, the shape of the circle is a circle, the diameter of the circle is almost the same as the width of the second belt A21 and the second belt B21, the width of the belt line is slightly larger than the diameter of the circle, and the height of the lower edge of the diverter baffle 23 from the belt line is just enough for the conveying distance of a drain pipe, thereby realizing the limitation of the overlapping drain pipes and ensuring the smooth conveyance of the drain pipes close to the belt line.

[0069] Connecting pipe side: The third belt 41 starts to convey, and the connecting pipes in the connecting pipe storage mechanism 3 are conveyed one by one onto the third belt 41. Specifically, the principle of conveying the connecting pipes one by one is that the connecting pipes are neatly stacked and placed in the storage box by hand, and the bottom connecting pipe is in direct contact with the third belt 41. After the third belt 41 is started, the connecting pipe can only be conveyed out of the storage box one at a time through the limit of the discharge port of the storage box driven by the third belt 41. Since the discharge port is designed to be larger than the outer shape of the connecting pipe, sometimes the discharge port still conveys two stacked connecting pipes at a time. When the connecting pipe is conveyed to the fifth detection photoelectric sensor 85, the stopper 44, that is, the cylinder, extends. If the connecting pipes are stacked at this time, the cylinder will limit the passage of the upper connecting pipe to ensure that the connecting pipes are conveyed one by one.

[0070] Grabbing side: When the drain pipe is transported to the fourth detection photoelectric sensor 84, the slide cylinder starts to move, driving the grabbing assembly 54 to move to the fourth detection photoelectric sensor 84, and then the lifting cylinder extends to move the clamping claw 550 to the inner circle of the drain pipe. After moving into place, the second driving member 544 is actuated, that is, the cylinder extends, so that the connecting rod 545 drives the rotating shaft 547 to rotate, and the rotating shaft 547 drives the triangular block to rotate, so that the slide of the sliding assembly 549 slides, thereby driving the clamping claw 550 to move outward to clamp the drain pipe. After the grabbing is completed, the lifting cylinder retracts, and then the slide cylinder moves to drive the grabbing assembly 54 to move above the third belt 41 line, waiting for the connecting pipe to be in place. The connecting pipe is transported by the third belt 41 to the sixth detection photoelectric sensor 86 and stops. Then the lifting cylinder extends to move the drainage pipe on the grabbing assembly 54 into the inner circle of the connecting pipe. Then the second driving member 544, that is, the cylinder retracts to drive the clamping claw 550 to move inward, thereby placing the drainage pipe into the inner circle of the connecting pipe. After the discharge is completed, the lifting cylinder retracts to complete the pairing and continue the next grabbing.

[0071] Once the connecting pipe and drain pipe are paired, they are conveyed to the underside of the detection mechanism 6. This mechanism then activates, and the detection camera 63 takes a photo of the paired drain pipe and connecting pipe. The photo is then compared with the template photo to detect whether the drain pipe is within the inner circle of the connecting pipe. The detection principle is to determine whether the drain pipe and connecting pipe are different colors (the drain pipe is white, and the connecting pipe is black). The color comparison of the images determines whether the drain pipe is within the connecting pipe. If the photos do not match after the test, the device will issue an alarm. If they do, the paired connecting pipe will continue to the packaging mechanism 7 for bagging and packaging. After bagging and packaging, the paired connecting pipe is transported to a tooling vehicle for storage, repeating the cycle.

[0072] Through the pairing packaging method of this embodiment, the entire process is automated, eliminating potential quality risks and process problems caused by human operation, and improving product quality; automation replaces manual labor, achieving efficiency improvement and staff control, and solving the problem of high labor costs in enterprises.

[0073] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
