Description

Technical Field

[0001] The present application relates to the technical field of production line equipment, and in particular to an assembly line and an assembly control method for a drainage connector for an air conditioner outdoor unit. Background Art

[0002] In the original production process, the drain joint of the air conditioner outdoor unit needs to be fed through a material frame and then manually assembled to the air conditioner outdoor unit. During this assembly process, due to the relatively small size of the drain joint, there may be assembly problems such as inadequate assembly, unreliable assembly, and missing assembly. In addition, specially arranging manual labor to assemble the drain joint wastes manpower and increases assembly costs. Moreover, in the case of batch assembly of drain joints, the assembly efficiency is limited, and the mass production assembly of the drain joints cannot be effectively realized. Summary of the invention

[0003] In view of this, the present application provides an assembly line and an assembly control method for a drain connector of an air conditioner outdoor unit, so as to achieve the purpose of automated assembly and assembly control of the drain connector of the air conditioner outdoor unit.

[0004] In the first aspect, the present application provides an assembly line for a drain joint of an air-conditioning outdoor unit, the assembly line comprising: a storage bin, the storage bin is arranged at the starting end of the assembly line, and is used to store the drain joint; a circular vibration plate, the circular vibration plate is arranged downstream of the storage bin, and is connected to the storage bin through a conveying mechanism; a linear vibration guide rail, the linear vibration guide rail is arranged downstream of the circular vibration plate, and is connected to the circular vibration plate; an air-conditioning outdoor unit conveyor line, the air-conditioning outdoor unit conveyor line is arranged at a position close to the linear vibration guide rail, and is used to convey the air-conditioning outdoor unit; a robot, the robot is arranged between the linear vibration guide rail and the air-conditioning outdoor unit conveyor line, and is used to grab the drain joint and assemble the drain joint to the air-conditioning outdoor unit.

[0005] Beneficial effect: The assembly line of the drain connector proposed in the present application can achieve the purpose of automatic sorting, automatic grabbing and automatic assembly of disorderly incoming drain connectors, thereby improving the assembly efficiency of the drain connector and the air conditioner outdoor unit.

[0006] Specifically, after the drainage joints are poured into the storage bin, the storage bin can store a rated amount of drainage joints, thereby avoiding frequent addition of materials to the storage bin, and the conveying mechanism starts to convey the drainage joints to the circular vibration plate, which sorts the disordered drainage joints by vibration, and then conveys the drainage joints to the linear vibration guide rail, which starts to send the drainage joints to the designated position, and the robot picks and assembles the drainage joints. The above equipment realizes automatic feeding control of the drainage joints and automatic assembly control of the drainage joints.

[0007] In an optional embodiment, the assembly line also includes a circular vibration detection sensor, which is arranged at the circular vibration plate, for detecting the drainage joint on the circular vibration plate; and / or, the assembly line also includes a linear vibration detection sensor, which is arranged at the linear vibration guide rail, for detecting the drainage joint on the linear vibration guide rail.

[0008] Beneficial effect: When the circular vibration detection sensor detects a signal that the circular vibration disk has no drainage joint, the controller of the assembly line controls the conveying mechanism to start conveying the drainage joint into the circular vibration disk until the circular vibration detection sensor detects a signal that the circular vibration disk has a drainage joint. The conveying mechanism stops conveying the drainage joint to the circular vibration disk, thereby realizing the incoming material control of the circular vibration disk.

[0009] When the direct vibration detection sensor detects the signal that there is no drainage joint on the linear vibration guide, the controller of the assembly line controls the circular vibration plate to start vibrating and transport the drainage joint to the linear vibration guide, until the direct vibration detection sensor detects the signal that there is a drainage joint on the linear vibration guide, and the circular vibration plate stops transporting the drainage joint to the linear vibration guide, thereby realizing the incoming material control of the linear vibration guide.

[0010] In an optional embodiment, the assembly line also includes an air conditioning detection sensor, which is arranged on the air conditioning outdoor unit conveyor line, for detecting the air conditioner on the air conditioning outdoor unit conveyor line; and / or, the assembly line also includes a material detection sensor, which is arranged on the air conditioning outdoor unit conveyor line, for detecting the drainage joint on the air conditioning outdoor unit conveyor line.

[0011] Beneficial effect: The air-conditioning outdoor unit is conveyed on the air-conditioning outdoor unit conveyor line. When the air-conditioning detection sensor detects that the air-conditioning outdoor unit has reached the specified position, the clamping mechanism of the air-conditioning outdoor unit conveyor line clamps the air-conditioning outdoor unit; when the material detection sensor detects that there is no signal at the material position of the air-conditioning outdoor unit conveyor line, it means that the placement position of the air-conditioning outdoor unit is normal. At this time, the air-conditioning outdoor unit has completed positioning, and the subsequent assembly of the drainage joint is ready. If the material detection sensor detects that there is a signal at the material position of the air-conditioning outdoor unit conveyor line, it means that there is a foreign object at the placement position of the air-conditioning outdoor unit. At this time, the assembly line will trigger an alarm to prompt manual processing.

[0012] In an optional embodiment, two baffles spaced at a preset distance are provided on the air-conditioning outdoor unit conveying line, and the two baffles are arranged to block the air-conditioning outdoor unit at two positions on the air-conditioning outdoor unit conveying line.

[0013] Beneficial effect: The air-conditioning outdoor unit is positioned twice at the starting position of the air-conditioning outdoor unit through two baffles, and the two material detection sensors at the two positioning positions detect whether the drain joint is in place. On the one hand, it can be detected whether the robot has completed the assembly of the drain joint, and on the other hand, it can be detected whether the drain joint of the air-conditioning outdoor unit falls off at the starting position, effectively improving the purpose of monitoring the assembly of the drain joint on the assembly line.

[0014] In an optional implementation, the two baffles include an upstream baffle and a downstream baffle, respectively. An upstream material detection sensor is disposed at the upstream baffle, and a downstream material detection sensor is disposed at the downstream baffle.

[0015] Beneficial effects: If the upstream material detection sensor detects the signal of the drain joint, it means that the drain joint is in place and the assembly is completed. If the upstream material detection sensor does not detect the signal of the drain joint, it means that the drain joint is not in place or the material is missed, and the programmable controller (PLC) will control the robot and the robot's fixture to continue to pick up the material and place it until the drain joint is in place; then the clamping mechanism on the air-conditioning outdoor unit conveyor line is released, and the upstream baffle on the air-conditioning outdoor unit conveyor line is lowered and released. When the upstream material detection sensor detects the signal of the drain joint, the upstream baffle on the air-conditioning outdoor unit conveyor line does not rise until the upstream material detection sensor does not detect the signal of the drain joint, and the upstream baffle on the air-conditioning outdoor unit conveyor line rises; when the downstream material detection sensor detects the signal of the drain joint, it means that the drain joint has not fallen off during the movement, and the downstream baffle is lowered and released. If the downstream material detection sensor does not detect the signal of the drain joint, it means that the drain joint has fallen off during the movement, and an alarm will be issued for manual processing.

[0016] In a second aspect, the present application provides an assembly control method for an assembly line, and the assembly control method is implemented through the assembly line for the drain joint of the air-conditioning outdoor unit of the first aspect of the present application, and the assembly control method includes: obtaining a first detection signal at a circular vibration disk and a second detection signal at a linear vibration guide rail; determining that a material storage bin is short of material or a material jam has occurred in a conveying mechanism based on an abnormality in the first detection signal; determining that a material jam has occurred in the circular vibration disk based on an abnormality in the second detection signal; and controlling the robot to grab the drain joint and assemble it to the air-conditioning outdoor unit based on the first detection signal and the second detection signal being normal.

[0017] Beneficial effect: After the drainage joints are poured into the storage bin, the storage bin can store a rated amount of drainage joints, thereby avoiding frequent addition of materials to the storage bin. The conveying mechanism starts to convey the drainage joints to the circular vibration plate. The circular vibration plate sorts the disordered drainage joints by vibration, and then conveys the drainage joints to the linear vibration guide rail. The linear vibration guide rail starts to send the drainage joints to the designated position, and the robot picks and assembles the drainage joints. The above equipment realizes automatic feeding control of the drainage joints and automatic assembly control of the drainage joints.

[0018] When the circular vibration detection sensor detects a signal that the circular vibration disk has no drainage joint, the controller of the assembly line controls the conveying mechanism to start conveying the drainage joint into the circular vibration disk, until the circular vibration detection sensor detects a signal that the circular vibration disk has a drainage joint, and the conveying mechanism stops conveying the drainage joint to the circular vibration disk, thereby realizing the incoming material control of the circular vibration disk.

[0019] When the direct vibration detection sensor detects the signal that there is no drainage joint on the linear vibration guide, the controller of the assembly line controls the circular vibration plate to start vibrating and transport the drainage joint to the linear vibration guide, until the direct vibration detection sensor detects the signal that there is a drainage joint on the linear vibration guide, and the circular vibration plate stops transporting the drainage joint to the linear vibration guide, thereby realizing the incoming material control of the linear vibration guide.

[0020] Furthermore, when the circular vibration detection sensor detects a signal that the circular vibration disk has no drainage joint and the set delay time is reached, it can be judged that the conveying mechanism is stuck or the storage bin is out of material. At this time, the assembly line will trigger an alarm to prompt manual processing; when the circular vibration detection sensor detects a signal of a drainage joint and the direct vibration detection sensor detects a signal without a drainage joint, and the set delay time is reached, it can be judged that the circular vibration disk is stuck. At this time, the assembly line will trigger an alarm and require manual processing; when the direct vibration detection sensor detects the signal of the drainage joint and the in-place detection sensor does not detect the signal of the drainage joint, and the set delay time is reached, it can be judged that the linear vibration guide is stuck. At this time, the assembly line will trigger an alarm and require manual processing.

[0021] In an optional embodiment, controlling the robot to grab the drain connector and assemble it to the air conditioner outdoor unit specifically includes: obtaining a third detection signal at the air conditioner on the air conditioner outdoor unit conveying line and a fourth detection signal at the drain connector; determining that the air conditioner has a conveying abnormality based on an abnormality in the third detection signal; determining that a foreign object is present at the drain connector based on an abnormality in the fourth detection signal; and controlling the robot to assemble the drain connector to the air conditioner outdoor unit based on both the third detection signal and the fourth detection signal being normal.

[0022] Beneficial effect: The air-conditioning outdoor unit is conveyed on the air-conditioning outdoor unit conveyor line. When the air-conditioning detection sensor detects that the air-conditioning outdoor unit has reached the specified position, the clamping mechanism of the air-conditioning outdoor unit conveyor line clamps the air-conditioning outdoor unit; when the material detection sensor detects that there is no signal at the material position of the air-conditioning outdoor unit conveyor line, it means that the placement position of the air-conditioning outdoor unit is normal. At this time, the air-conditioning outdoor unit has completed positioning, and the subsequent assembly of the drainage joint is ready. If the material detection sensor detects that there is a signal at the material position of the air-conditioning outdoor unit conveyor line, it means that there is a foreign object at the placement position of the air-conditioning outdoor unit. At this time, the assembly line will trigger an alarm to prompt manual processing.

[0023] In an optional embodiment, after controlling the robot to assemble the drain joint to the air conditioner outdoor unit, the process further includes: obtaining a fifth detection signal at the drain joint, and determining whether the drain joint is in place according to the fifth detection signal.

[0024] Beneficial effect: If the material detection sensor detects the signal of the drain joint, it means that the drain joint is in place and the assembly is completed. If the material detection sensor does not detect the signal of the drain joint, it means that the drain joint is not in place or the drain joint is missed. At this time, the controller of the assembly line will control the robot's clamp to continue to pick up and assemble materials until the drain joint is assembled in place.

[0025] In an optional embodiment, after determining whether the drain joint is in place according to the fifth detection signal, the method also includes: after driving the air conditioner outdoor unit delivery line to run a preset distance, obtaining a sixth detection signal at the drain joint, and determining whether the drain joint is detached according to the sixth detection signal.

[0026] Beneficial effect: The air-conditioning outdoor unit conveyor line runs a preset distance and positions the air-conditioning outdoor unit twice. The two material detection sensors at the two positions detect whether the drain joint is in place. On the one hand, it can detect whether the robot has completed the assembly of the drain joint. On the other hand, it can detect whether the drain joint of the air-conditioning outdoor unit falls off at the starting position, which effectively improves the purpose of monitoring the assembly of the drain joint on the assembly line.

[0027] In an optional embodiment, before driving the air conditioner outdoor unit conveyor line to run a preset distance, the method further includes: driving the robot to run to a position away from the linear vibration guide rail.

[0028] Beneficial effect: When the air conditioner outdoor unit is in place and ready, the robot is controlled to run to the placement point, and then the robot's clamp is controlled to release, and the robot and the clamp are controlled to a safe point, so as to reduce the collision between the robot's clamp and the air conditioner outdoor unit.

[0047] like Figures 1 to 3 As shown, according to an embodiment of the present application, on the one hand, the present application provides an assembly line 100 for a drain connector for an air-conditioning outdoor unit 60, and the assembly line 100 includes: a storage bin 10, the storage bin 10 is arranged at the starting end of the assembly line 100, and is used to store the drain connector; a circular vibration plate 20, the circular vibration plate 20 is arranged downstream of the storage bin 10, and is connected to the storage bin 10 through a conveying mechanism 11; a linear vibration guide rail 30, the linear vibration guide rail 30 is arranged downstream of the circular vibration plate 20, and is connected to the circular vibration plate 20; an air-conditioning outdoor unit conveyor line 40, the air-conditioning outdoor unit conveyor line 40 is arranged at a position close to the linear vibration guide rail 30, and is used to convey the air-conditioning outdoor unit 60; a robot 50, the robot 50 is arranged between the linear vibration guide rail 30 and the air-conditioning outdoor unit conveyor line 40, and is used to grab the drain connector and assemble the drain connector to the air-conditioning outdoor unit 60.

[0048] In this embodiment, the assembly line 100 of the drain connector proposed in this application can achieve the purpose of automatic sorting, automatic grabbing and automatic assembly of disorderly incoming drain connectors, thereby improving the assembly efficiency of the drain connector and the air conditioner outdoor unit 60.

[0049] Specifically, after the drainage joints are poured into the storage bin 10, the storage bin 10 can store a rated amount of drainage joints, thereby avoiding frequent addition of materials to the storage bin 10, and the conveying mechanism 11 is started to convey the drainage joints to the circular vibration plate 20, and the circular vibration plate 20 sorts the disordered drainage joints by vibration, and then conveys the drainage joints to the linear vibration guide rail 30, and the linear vibration guide rail 30 is started to convey the drainage joints to the designated position, and the robot 50 takes the material and assembles the drainage joints. The above-mentioned equipment realizes the automatic feeding control of the drainage joints and the automatic assembly control of the drainage joints.

[0050] like Figures 1 to 3 As shown, in some embodiments, the assembly line 100 also includes a circular vibration detection sensor 21, which is arranged at the circular vibration plate 20, for detecting the drainage joint on the circular vibration plate 20; and / or, the assembly line 100 also includes a linear vibration detection sensor 31, which is arranged at the linear vibration guide rail 30, for detecting the drainage joint on the linear vibration guide rail 30.

[0051] In the above embodiment, when the circular vibration detection sensor 21 detects a signal that the circular vibration disk 20 has no drainage connector, the controller of the assembly line 100 controls the conveying mechanism 11 to start conveying the drainage connector into the circular vibration disk 20 until the circular vibration detection sensor 21 detects a signal that the circular vibration disk 20 has a drainage connector. The conveying mechanism 11 stops conveying the drainage connector to the circular vibration disk 20, thereby realizing the incoming material control of the circular vibration disk 20.

[0052] When the direct vibration detection sensor 31 detects a signal that there is no drainage joint on the linear vibration guide rail 30, the controller of the assembly line 100 controls the circular vibration plate 20 to start vibrating and transport the drainage joint to the linear vibration guide rail 30, until the direct vibration detection sensor 31 detects a signal that there is a drainage joint on the linear vibration guide rail 30, and the circular vibration plate 20 stops transporting the drainage joint to the linear vibration guide rail 30, thereby realizing the incoming material control of the linear vibration guide rail 30.

[0053] like Figures 1 to 3 As shown, in some embodiments, the assembly line 100 also includes an air conditioning detection sensor 61, which is arranged on the air conditioning outdoor unit conveyor line 40, and is used to detect the air conditioner on the air conditioning outdoor unit conveyor line 40; and / or, the assembly line 100 also includes a material detection sensor, which is arranged on the air conditioning outdoor unit conveyor line 40, and is used to detect the drainage joint on the air conditioning outdoor unit conveyor line 40.

[0054] In this embodiment, the air-conditioning outdoor unit 60 is transported on the air-conditioning outdoor unit conveyor line 40. When the air-conditioning detection sensor 61 detects that the air-conditioning outdoor unit 60 has reached the specified position, the clamping mechanism 62 of the air-conditioning outdoor unit conveyor line 40 clamps the air-conditioning outdoor unit 60. When the material detection sensor detects that there is no signal at the material position of the air-conditioning outdoor unit conveyor line 40, it means that the placement position of the air-conditioning outdoor unit 60 is normal. At this time, the air-conditioning outdoor unit 60 has completed positioning, and the subsequent assembly work of the drainage joint is ready. If the material detection sensor detects that there is a signal at the material position of the air-conditioning outdoor unit conveyor line 40, it means that there is a foreign object at the placement position of the air-conditioning outdoor unit 60. At this time, the assembly line 100 will trigger an alarm to prompt manual processing.

[0055] like Figures 1 to 3 As shown, in some embodiments, two baffles spaced a preset distance apart are provided on the air-conditioning outdoor unit conveying line 40 , and the two baffles are arranged to block the air-conditioning outdoor unit 60 at two positions on the air-conditioning outdoor unit conveying line 40 .

[0056] In the above embodiment, the air-conditioning outdoor unit 60 is positioned twice at the starting position of the air-conditioning outdoor unit 60 by two baffles, and two material detection sensors at the two positioning positions detect whether the drain joint is assembled in place. On the one hand, it can be achieved to detect whether the robot 50 has completed the assembly of the drain joint, and on the other hand, it can be achieved to detect whether the drain joint of the air-conditioning outdoor unit 60 falls off at the starting position, thereby effectively improving the purpose of monitoring the assembly of the drain joint by the assembly line 100.

[0057] like Figures 1 to 3 As shown, in an optional embodiment, the two baffles include an upstream baffle 43 and a downstream baffle 44 , respectively. An upstream material detection sensor 41 is provided at the upstream baffle 43 , and a downstream material detection sensor 42 is provided at the downstream baffle 44 .

[0058] In this embodiment, if the upstream material detection sensor 41 detects the signal of the drainage joint, it means that the drainage joint is in place and the assembly is completed. If the upstream material detection sensor 41 does not detect the signal of the drainage joint, it means that the drainage joint is not in place or the material is missed, and the programmable controller (PLC) will control the robot 50 and the clamp 51 of the robot 50 to continue to pick up the material and place it again until the drainage joint is in place; then the clamping mechanism 62 on the air-conditioning outdoor unit conveying line 40 is released, and the upstream baffle 43 on the air-conditioning outdoor unit conveying line 40 is lowered and released. When the upstream material detection sensor 41 detects the signal of the drainage joint, the upstream baffle 43 on the air-conditioning outdoor unit conveying line 40 does not rise until the upstream material detection sensor 41 does not detect the signal of the drainage joint, and the upstream baffle 43 on the air-conditioning outdoor unit conveying line 40 rises; when the downstream material detection sensor 42 detects the signal of the drainage joint, it means that the drainage joint has not fallen during the movement, and the downstream baffle 44 is lowered and released. If the downstream material detection sensor 42 does not detect the signal of the drainage joint, it means that the drainage joint has fallen during the movement, and an alarm will be issued for manual processing.

[0059] like Figures 4 to 6 As shown, in the second aspect, the present application provides an assembly control method for an assembly line 100, and the assembly control method is implemented through the assembly line 100 for the drainage joint of the air-conditioning outdoor unit 60 of the first aspect of the present application, and the assembly control method includes: obtaining a first detection signal at the circular vibration plate 20 and a second detection signal at the linear vibration guide rail 30; determining that the material storage bin 10 is short of material or the conveying mechanism 11 is jammed based on the abnormality of the first detection signal; determining that the circular vibration plate 20 is jammed based on the abnormality of the second detection signal; and controlling the robot 50 to grab the drainage joint and assemble it to the air-conditioning outdoor unit 60 based on the fact that both the first detection signal and the second detection signal are normal.

[0060] In the above embodiment, after the drainage joints are poured into the storage bin 10, the storage bin 10 can store a rated amount of drainage joints, thereby avoiding frequent feeding into the storage bin 10, and the conveying mechanism 11 starts to convey the drainage joints to the circular vibration plate 20, and the circular vibration plate 20 sorts the disordered drainage joints by vibration, and then conveys the drainage joints to the linear vibration guide rail 30, and the linear vibration guide rail 30 starts to convey the drainage joints to the designated position, and the robot 50 picks and assembles the drainage joints. The above equipment realizes automatic feeding control of the drainage joints and automatic assembly control of the drainage joints.

[0061] When the circular vibration detection sensor 21 detects a signal that the circular vibration disk 20 has no drainage connector, the controller of the assembly line 100 controls the conveying mechanism 11 to start conveying the drainage connector into the circular vibration disk 20 until the circular vibration detection sensor 21 detects a signal that the circular vibration disk 20 has a drainage connector. The conveying mechanism 11 stops conveying the drainage connector to the circular vibration disk 20, thereby achieving incoming material control of the circular vibration disk 20.

[0062] When the direct vibration detection sensor 31 detects a signal that there is no drainage joint on the linear vibration guide rail 30, the controller of the assembly line 100 controls the circular vibration plate 20 to start vibrating and transport the drainage joint to the linear vibration guide rail 30, until the direct vibration detection sensor 31 detects a signal that there is a drainage joint on the linear vibration guide rail 30, and the circular vibration plate 20 stops transporting the drainage joint to the linear vibration guide rail 30, thereby realizing the incoming material control of the linear vibration guide rail 30.

[0063] like Figures 4 to 6 As shown, in some embodiments, controlling the robot 50 to grab the drain connector and assemble it to the air-conditioning outdoor unit 60 specifically includes: obtaining a third detection signal at the air conditioner on the air-conditioning outdoor unit conveying line 40 and a fourth detection signal at the drain connector; determining that an abnormal conveying phenomenon occurs in the air conditioner based on an abnormal third detection signal; determining that a foreign body occurs at the drain connector based on an abnormal fourth detection signal; and controlling the robot 50 to assemble the drain connector to the air-conditioning outdoor unit 60 based on both the third detection signal and the fourth detection signal being normal.

[0064] In this embodiment, the air-conditioning outdoor unit 60 is transported on the air-conditioning outdoor unit conveyor line 40. When the air-conditioning detection sensor 61 detects that the air-conditioning outdoor unit 60 has reached the specified position, the clamping mechanism 62 of the air-conditioning outdoor unit conveyor line 40 clamps the air-conditioning outdoor unit 60. When the material detection sensor detects that there is no signal at the material position of the air-conditioning outdoor unit conveyor line 40, it means that the placement position of the air-conditioning outdoor unit 60 is normal. At this time, the air-conditioning outdoor unit 60 has completed positioning, and the subsequent assembly work of the drainage joint is ready. If the material detection sensor detects that there is a signal at the material position of the air-conditioning outdoor unit conveyor line 40, it means that there is a foreign object at the placement position of the air-conditioning outdoor unit 60. At this time, the assembly line 100 will trigger an alarm to prompt manual processing.

[0065] like Figures 4 to 6 As shown, in some embodiments, after controlling the robot 50 to assemble the drain joint to the air conditioner outdoor unit 60, it also includes: obtaining a fifth detection signal at the drain joint, and determining whether the drain joint is assembled in place according to the fifth detection signal.

[0066] In this embodiment, if the material detection sensor detects the signal of the drain joint, it means that the drain joint is in place and the assembly is completed. If the material detection sensor cannot detect the signal of the drain joint, it means that the drain joint is not in place or the drain joint is missed. At this time, the controller of the assembly line 100 will control the clamp 51 of the robot 50 to continue to pick up and assemble materials until the drain joint is assembled in place.

[0067] like Figures 4 to 6 As shown, in some embodiments, after determining whether the drain joint is in place based on the fifth detection signal, it also includes: after driving the air conditioner outdoor unit delivery line 40 to run a preset distance, obtaining a sixth detection signal at the drain joint, and determining whether the drain joint is detached based on the sixth detection signal.

[0068] In this embodiment, the air-conditioning outdoor unit conveyor line 40 runs a preset distance and positions the air-conditioning outdoor unit 60 twice. Two material detection sensors at the two positions detect whether the drain joint is in place. On the one hand, it can detect whether the robot 50 has completed the assembly of the drain joint. On the other hand, it can detect whether the drain joint of the air-conditioning outdoor unit 60 falls off at the starting position, thereby effectively improving the purpose of monitoring the assembly of the drain joint by the assembly line 100.

[0069] like Figures 4 to 6 As shown, in an optional embodiment, driving the air conditioner outdoor unit conveyor line 40 to run a preset distance also includes: driving the robot 50 to run to a position away from the linear vibration guide rail 30.

[0070] In this embodiment, when the air conditioner outdoor unit 60 is in place and ready, the robot 50 is controlled to run to the placement point, and then the clamp 51 of the robot 50 is controlled to release, and the robot 50 and the clamp 51 are controlled to a safe point, so as to reduce the collision between the clamp 51 of the robot 50 and the air conditioner outdoor unit 60.

[0071] According to the assembly line 100 for the drainage connector of the air conditioner outdoor unit 60 provided in the embodiment of the present application, it is possible to achieve the effect of parallel execution of the automatic material feeding control process and the automatic material taking and assembly control process.

[0072] like Figures 1 to 6 As shown, the assembly line 100 for the drainage connector of the air conditioner outdoor unit 60 and the assembly control method of the assembly line 100 according to an embodiment of the present application are generally described below.

[0073] The automatic feeding control process includes: manually or automatically transporting equipment to pour the drainage joint into the storage bin 10, and the storage bin 10 can store the amount produced by the assembly line 100 in one day, so as to avoid frequent feeding to the storage bin 10; when the circular vibration detection sensor 21 detects a signal that there is no drainage joint on the circular vibration plate 20, the programmable controller (PLC) of the assembly line 100 controls the conveying mechanism 11 (climbing belt line) to start, and convey the drainage joint into the circular vibration plate 20, until the circular vibration detection sensor 21 detects a signal that there is a drainage joint, and the conveying mechanism 11 (climbing belt line) stops conveying the drainage joint;

[0074] When the circular vibration detection sensor 21 detects the signal of the drainage joint on the circular vibration plate 20, the programmable controller (PLC) of the assembly line 100 controls the circular vibration plate 20 to start vibration and transport the drainage joint to the linear vibration guide 30. When the linear vibration detection sensor 31 detects the signal of the drainage joint on the linear vibration guide 30, the circular vibration plate 20 stops vibrating; when the in-place detection sensor 32 on the linear vibration guide 30 does not detect the signal of the drainage joint, the programmable controller (PLC) controls the linear vibration guide 30 to start and send the drainage joint to the specified position until the in-place detection sensor 32 on the linear vibration guide 30 detects the signal of the drainage joint, and the linear vibration guide 30 stops running and waits for the robot 50 to pick up the material. Through the automatic feeding control process of the embodiment of the present application, the effect of disorderly incoming and orderly outgoing of drainage joints can be achieved.

[0075] Automatic feeding fool-proof control process: when the circular vibration detection sensor 21 detects the signal that the circular vibration disk 20 has no drainage joint, and the set delay time is reached, it can be judged that the conveying mechanism 11 is stuck or the storage bin 10 is out of material. At this time, the assembly line 100 will trigger an alarm to prompt manual processing; when the circular vibration detection sensor 21 detects the signal of a drainage joint and the direct vibration detection sensor 31 detects the signal without a drainage joint, and the set delay time is reached, it can be judged that the circular vibration disk 20 is stuck. At this time, the assembly line 100 will trigger an alarm and require manual processing; when the direct vibration detection sensor 31 detects the signal of the drainage joint and the in-place detection sensor 32 does not detect the signal of the drainage joint, and the set delay time is reached, it can be judged that the linear vibration guide 30 is stuck. At this time, the assembly line 100 will trigger an alarm and require manual processing.

[0076] The initial state of the automatic material picking and assembly process when it is started up: the robot 50 and the clamp 51 of the robot 50 are located at the initial safety point, the two baffles are in the rising blocking state on the air-conditioning outdoor unit conveyor line 40, and the clamping mechanism 62 on the air-conditioning outdoor unit conveyor line 40 is in the open state.

[0077] The initial posture of the air-conditioning outdoor unit conveyor line 40: the upstream baffle 43 on the air-conditioning outdoor unit conveyor line 40 is in an upward state, and the air-conditioning outdoor unit 60 is conveyed on the air-conditioning outdoor unit conveyor line 40. When the air-conditioning detection sensor 61 on the air-conditioning outdoor unit conveyor line 40 detects that the air-conditioning outdoor unit 60 is in place, the clamping mechanism 62 of the air-conditioning outdoor unit conveyor line 40 clamps the air-conditioning outdoor unit 60; if the upstream material detection sensor 41 at the upstream baffle 43 does not detect the signal of the drainage joint, it means that the placement position of the air-conditioning outdoor unit 60 is normal. At this time, the air-conditioning outdoor unit 60 has completed positioning and is ready; if the upstream material detection sensor 41 at the upstream baffle 43 detects the signal of the drainage joint, it means that there is a foreign object at the placement position of the air-conditioning outdoor unit 60, and an alarm will be issued and manual processing is required.

[0078] The automatic material picking and assembly process includes: the programmable controller (PLC) first controls the robot 50 and the clamp 51 of the robot 50 to reach the initial safety point, so as to prevent the robot 50 from directly going to the material picking position and colliding with the machine when it is started for the first time, and then drives the robot 50 to move to the waiting material picking point to pick up materials, the clamp 51 of the robot 50 clamps the drainage joint, and then controls the robot 50 and the clamp 51 of the robot 50 to reach the waiting placement position of the robot 50; if the air-conditioning outdoor unit 60 is in place but not ready, the PLC controls the robot 50 to continue waiting at the waiting placement point; if the air-conditioning outdoor unit 60 is in place and ready, controls the robot 50 to the placement point, and then controls the clamp 51 of the robot 50 to loosen the drainage joint, and controls the robot 50 and the clamp 51 of the robot 50 to the safety point, so as to reduce the phenomenon of the clamp 51 of the robot 50 colliding with the air-conditioning outdoor unit 60.

[0079] If the upstream material detection sensor 41 detects the signal of the drainage joint, it means that the drainage joint is in place and the assembly is completed. If the upstream material detection sensor 41 does not detect the signal of the drainage joint, it means that the drainage joint is not in place or the material is missed, and the programmable controller (PLC) will control the robot 50 and the clamp 51 of the robot 50 to continue to pick up the material and place it again until the drainage joint is in place; then the clamping mechanism 62 on the air-conditioning outdoor unit conveying line 40 is released, and the upstream baffle 43 on the air-conditioning outdoor unit conveying line 40 is lowered and released. When the upstream material detection sensor 41 detects the signal of the drainage joint, the upstream baffle 43 on the air-conditioning outdoor unit conveying line 40 does not rise until the upstream material detection sensor 41 does not detect the signal of the drainage joint, and the upstream baffle 43 on the air-conditioning outdoor unit conveying line 40 rises; when the downstream material detection sensor 42 detects the signal of the drainage joint, it means that the drainage joint has not fallen during the movement, and the downstream baffle 44 is lowered and released. If the downstream material detection sensor 42 does not detect the signal of the drainage joint, it means that the drainage joint has fallen during the movement, and an alarm will be issued for manual processing.

[0080] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations are all within the scope defined by the appended claims.
