Description

Technical Field

[0001] This utility model relates to the field of nozzle assembly technology, specifically to a semi-automatic nozzle assembly machine. Background Technology

[0002] In modern spraying, cleaning, and liquid transfer processes, nozzles are core components, and their performance and stability directly affect the overall system's efficiency and effectiveness. One nozzle design integrates multiple parts, including a water distribution body, a cap, a connecting rod, an aerator, a retaining ring, an anti-siphon component, and a filter. These parts require precise alignment and positioning during assembly to ensure the nozzle's overall performance.

[0003] The water distributor body serves as the main structure of the nozzle, with two central bolts rotatably connected to it. During assembly, the cap must first be inserted into the central bolts to securely fasten it onto the water distributor body. Next, one end of the connecting rod is connected to the central bolt, and by rotating the central bolt, that end of the connecting rod is restrained on the bolt to ensure stable operation. The aerator is then fixed to the water distributor body via a screw connection. The outer casing is then fitted onto the water distributor body. Finally, the retaining ring, anti-siphon component, and filter screen are sequentially installed onto the water distributor body to form the complete nozzle structure.

[0004] However, the assembly process of this nozzle is highly dependent on manual operation. Given the large number and small size of the nozzle parts, manual assembly is prone to oversights or improper installation, which can lead to decreased nozzle performance or even malfunctions, severely impacting its effectiveness and stability. Furthermore, manual assembly is inefficient and cannot meet the requirements of large-scale production and rapid market response.

[0005] Given the many shortcomings of existing manual assembly methods, it is necessary to develop a semi-automatic nozzle assembly machine, which aims to replace manual labor in assembling most of the nozzle parts through mechanization and automation, especially for those small parts that are difficult to assemble. Utility Model Content

[0006] (1) Technical problems solved

[0007] This invention provides a semi-automatic nozzle assembly machine, which can at least solve the technical problem of how to improve the assembly quality and efficiency of nozzles.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a semi-automatic nozzle assembly machine, comprising:

[0010] frame;

[0011] The assembly conveyor line, located on the frame, is used to transport the water distribution body. Along the conveying direction, the assembly conveyor line is provided with the following stations in sequence: cover installation station, connecting rod plate installation station, aerator installation station, fixing ring installation station, anti-siphon component installation station, and filter screen installation station.

[0012] The first feeding mechanism and six second feeding mechanisms are all mounted on the frame. The first feeding mechanism is used to move the water distribution body to the cap installation station of the assembly conveyor line. The six second feeding mechanisms are respectively positioned opposite the cap installation station, connecting rod plate installation station, aerator installation station, fixing ring installation station, anti-siphon component installation station, and filter screen installation station, and are respectively used to move the cap, connecting rod plate, aerator, fixing ring, anti-siphon component, and filter screen to the water distribution body at the corresponding station.

[0013] Further configuration includes a water distribution loading station and a material storage station on the aforementioned frame; the first loading mechanism includes:

[0014] At least two material trays are stacked on the storage station of the frame and are provided with a limiting groove for placing and limiting the water distribution body;

[0015] The material tray drive assembly, located on the frame, is used to transfer the material tray located at the bottom layer from the storage station to the water distribution loading station;

[0016] The first robotic arm, mounted on the frame, is used to transfer the water distribution bodies one by one from the water distribution body loading station to the cover installation station.

[0017] Further configuration: the aforementioned material tray drive assembly includes a linear displacement drive and a telescopic drive. The linear displacement drive is mounted on the frame and is connected to the telescopic drive for driving the telescopic drive to move back and forth between the material feeding station and the material storage station. The telescopic drive is used to drive the material tray to rise or fall.

[0018] The frame includes a storage rack and at least three carrier blocks. The storage rack is located on the storage station, and the carrier blocks are rotatably mounted on the storage rack. Each carrier block includes a first end and a second end. The second end is located below the first end, and a guide surface is provided on the side of the second end facing the storage station. The guide surface is used to abut against the material tray to drive the first end to rotate in a direction closer to the storage station. This allows the first ends of the at least three carrier blocks to combine to form a bearing surface for supporting the material tray. The weight of the second end is greater than the weight of the first end, which is used to drive the first end to rotate in a direction away from the storage station.

[0019] Furthermore, the aforementioned second end is provided with a sliding groove, and the frame is also provided with a limiting post that slides in conjunction with the sliding groove.

[0020] Furthermore, the aforementioned semi-automatic nozzle assembly machine also includes:

[0021] Three arrival detection mechanisms are located above the assembly conveyor line. One arrival detection mechanism is located between the cap installation station and the connecting rod installation station to detect whether the cap is inserted into the central plug of the water distribution body. Another arrival detection mechanism is located between the connecting rod installation station and the aerator installation station to detect whether one end of the connecting rod is inserted into a central plug. A third arrival detection mechanism is located between the fixing ring installation station and the anti-siphon component installation station to detect whether the fixing ring is installed on the water distribution body.

[0022] Two depth detection mechanisms are located above the assembly conveyor line. One depth detection mechanism is located between the bubbler installation station and the fixing ring installation station to detect the screw-in depth of the bubbler. The other depth detection mechanism is located between the anti-siphon component installation station and the filter screen installation station to detect the installation depth of the anti-siphon component.

[0023] Furthermore, the aforementioned semi-automatic nozzle assembly machine also includes an airtightness testing mechanism. The airtightness testing mechanism is located above the assembly conveyor line and between the bubbler installation station and the fixing ring installation station, and is used to test the airtightness of the internal passage of the nozzle.

[0024] Furthermore, the aforementioned semi-automatic nozzle assembly machine also includes two pressing mechanisms. One pressing mechanism is located between the cap mounting station and the connecting rod mounting station, and the other pressing mechanism is located between the connecting rod mounting station and the bubbler mounting station. The pressing mechanism includes a pressing block and a pressing block drive component. The pressing block drive component is mounted on the frame and is connected to the pressing block in a transmission manner. The pressing block drive component is used to drive the pressing block to press down the cap or connecting rod.

[0025] Furthermore, the aforementioned semi-automatic nozzle assembly machine also includes two center bolt rotation mechanisms. One center bolt rotation mechanism is located between the cap mounting station and the connecting rod mounting station and is used to rotate the center bolt so that one end of the connecting rod can be connected. The other center bolt rotation mechanism is located between the connecting rod mounting station and the bubbler mounting station and is used to rotate the center bolt so that one end of the connecting rod can be restricted to the center bolt.

[0026] Further configuration: The aforementioned assembly conveyor line includes a first conveyor line, a turntable, a transfer mechanism, and a second conveyor line mounted on a frame. The cap installation station and the connecting rod plate installation station are located on the first conveyor line, the aerator installation station is located on the turntable, and the fixing ring installation station, the anti-siphon component installation station, and the filter screen installation station are located on the second conveyor line. The transfer mechanism is used to transfer the water distribution body from the first conveyor line to the aerator installation station on the turntable.

[0027] Further, the aforementioned turntable is provided with at least three clamping members, which are distributed in a ring at equal intervals for clamping or releasing the water distribution body.

[0028] (III) Beneficial Effects

[0029] Compared with the prior art, the semi-automatic nozzle assembly machine provided by this utility model has the following features:

[0030] Beneficial effects:

[0031] When using the semi-automatic nozzle assembly machine provided by this utility model, firstly, the first feeding mechanism moves the water distributor to the cap installation station of the assembly conveyor line. The second feeding mechanism corresponding to the cap installation station moves the cap to the water distributor at that station, so that the cap is inserted into the center bolt of the water distributor. Next, the assembly conveyor line sequentially conveys the water distributor to the connecting rod installation station and the aerator installation station. During the conveying process, the second feeding mechanisms corresponding to the two stations move the connecting rod and the aerator to the water distributor at the corresponding stations, respectively. Then, the assembly conveyor line moves the water distributor out of the aerator installation station, and the operator manually attaches the outer shell to the water distributor and places the water distributor on the fixing ring installation station of the assembly conveyor line. Finally, the above steps are repeated, with the second feeding mechanism and the assembly conveyor line cooperating to sequentially install the fixing ring, anti-siphon component, and filter screen onto the water distributor. It can be seen that the semi-automatic nozzle assembly machine, through the cooperation of the assembly conveyor line, the first feeding mechanism and six second feeding mechanisms, can replace manual labor to assemble small parts such as caps, connecting rods, aerators, fixing rings, anti-siphon parts and filters on the water distribution body, avoiding the situation of missing parts, thereby effectively improving the assembly quality and efficiency of the nozzle.

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] This invention provides a semi-automatic nozzle assembly machine to address the problem of how to improve the assembly quality and efficiency of nozzles.

[0052] See Figure 1 As shown, Figure 1 The image shows a perspective view of the semi-automatic nozzle assembly machine in the embodiment. The semi-automatic nozzle assembly machine includes a frame 101, an assembly conveyor line 102, a first feeding mechanism 103, and six second feeding mechanisms 104.

[0053] Assembly conveyor line 102 is installed on frame 101 and is used to convey water body 201. Assembly conveyor line 102 is provided with the following stations in sequence along the conveying direction: cover installation station 1021, connecting rod plate installation station 1022, aerator installation station 1023, fixing ring installation station 1024, anti-siphon component installation station 1025, and filter screen installation station 1026.

[0054] The first feeding mechanism 103 and six second feeding mechanisms 104 are all mounted on the frame 101. The first feeding mechanism 103 is used to move the water distribution body 201 to the cap installation station 1021 of the assembly conveyor line 102. The six second feeding mechanisms 104 are respectively positioned opposite the cap installation station 1021, the connecting rod plate installation station 1022, the aerator installation station 1023, the fixing ring installation station 1024, the anti-siphon component installation station 1025, and the filter screen installation station 1026, and are respectively used to move the cap 202, the connecting rod plate 203, the aerator 204, the fixing ring 205, the anti-siphon component 206, and the filter screen 207 to the water distribution body 201 at the corresponding station.

[0055] When using the semi-automatic nozzle assembly machine described above, firstly, the first feeding mechanism 103 moves the water distributor 201 to the cap mounting station 1021 of the assembly conveyor line 102; then, the second feeding mechanism 104 corresponding to the cap mounting station 1021 moves the cap 202 to the water distributor 201 at that station, so that the cap 202 is inserted into the center bolt 2011 of the water distributor 201; next, the assembly conveyor line 102 moves the water distributor 201 from the cap mounting station 1021 to the connecting rod mounting station 1022, and at the same time, the second feeding mechanism 104 corresponding to the connecting rod mounting station 1022 moves the connecting rod 203 to the water distributor 201 at that station, so that one end of the connecting rod 203 is connected to the center bolt 2011 of the water distributor 201. The center plug 2011 is connected; the assembly conveyor line 102 moves the water separator 201 to the aerator installation station 1023 again. The second feeding mechanism 104 corresponding to the aerator installation station 1023 moves the aerator 204 onto the water separator 201 at that station. Then, the assembly conveyor line 102 moves the water separator 201 out of the aerator installation station 1023. The worker then manually attaches the outer shell 208 to the water separator 201 and places the water separator 201 onto the fixing ring installation station 1024 of the assembly conveyor line 102. Finally, the above steps are repeated. The second feeding mechanism 104 and the assembly conveyor line 102 cooperate to install the fixing ring 205, the anti-siphon component 206, and the filter screen 207 onto the water separator 201 in sequence. As can be seen, the semi-automatic nozzle assembly machine, through the assembly conveyor line 102, the first feeding mechanism 103 and six second feeding mechanisms 104, can replace manual labor to assemble small parts such as the cover 202, connecting rod plate 203, aerator 204, fixing ring 205, anti-siphon component 206 and filter screen 207 onto the water distribution body 201, avoiding the situation of missing parts, thereby effectively improving the assembly quality and efficiency of the nozzle.

[0056] See Figure 1 and Figure 2 As shown, Figure 2The diagram illustrates the structure of the first feeding mechanism in one embodiment. In one implementation of the frame 101 and the first feeding mechanism 103, the frame 101 is provided with a water distribution body feeding station 1011 and a storage station 1012. The first feeding mechanism 103 includes a material tray 1031, a material tray drive assembly 1032, and a first robotic arm 1033. At least two material trays 1031 are stacked on the storage station 1012 of the frame 101. Each material tray 1031 has a limiting groove 10311 for placing and limiting the water distribution body 201. The material tray drive assembly 1032 is mounted on the frame 101 and is used to transfer the lowest material tray 1031 from the storage station 1012 to the water distribution body feeding station 1011. The first robotic arm 1033 is mounted on the frame 101 and is used to transfer the water separators 201 one by one from the water separator loading station 1011 to the cap mounting station 1021. In this way, the semi-automatic nozzle assembly machine can store water separators 201 to be assembled in batches through the material tray 1031. During assembly, the material tray drive component 1032 and the first robotic arm 1033 cooperate to realize the automatic loading of water separators 201, thereby improving the nozzle assembly efficiency.

[0057] The aforementioned tray 1031 may have multiple limiting grooves 10311 evenly distributed to store large quantities of water separators 201 to be assembled. The aforementioned first robotic arm 1033 may use an existing robotic arm.

[0058] See Figure 2As shown, in one embodiment of the material tray drive assembly 1032, the material tray drive assembly 1032 includes a linear displacement drive member 10321 and a telescopic drive member 10322. The linear displacement drive member 10321 is mounted on the frame 101 and is driveably connected to the telescopic drive member 10322, used to drive the telescopic drive member 10322 to reciprocate between the water distribution loading station 1011 and the storage station 1012. The telescopic drive member 10322 is used to drive the material tray 1031 to rise or fall. The frame 101 includes a storage rack 1014 and at least three carrier blocks 1013. The storage rack 1014 is located on the storage station 1012, and the carrier blocks 1013 are rotatably connected to the storage rack 1014. The carrier block 1013 includes a first end 10131 and a second end 10132. The second end 10132 is located below the first end 10131, and the side of the second end 10132 facing the storage station 1012 has a guide surface 10133. The guide surface 10133 is used to abut against the material tray 1031 to drive the first end 10131 to rotate in a direction closer to the storage station 1012, thereby combining the first ends 10131 of at least three carrier blocks 1013 to form a bearing surface 10134 for supporting the material tray 1031. The weight of the second end 10132 is greater than the weight of the first end 10131, which is used to drive the first end 10131 to rotate in a direction away from the storage station 1012. Thus, during the material feeding and water distribution process 201, firstly, the linear displacement drive 10321 drives the telescopic drive 10322 to move to the storage station 1012. Then, the telescopic drive 10322 drives the material tray 1031 located at the bottom of the storage station 1012 to rise away from the bearing surface 10134. At this time, under the gravity of the second end 10132, the first end 10131 rotates away from the storage station 1012. The telescopic drive 10322 then drives the material tray 1031 to descend, thus smoothly moving the material tray 1031 downwards out of the storage station 1012. During the process, it will abut against the guide surface 10133, overcome the gravity of the second end 10132, thereby driving the first end 10131 to rotate towards the storage station 1012, forming the bearing surface 10134 again, bearing the remaining material trays 1031 of the storage station 1012, preventing the remaining material trays 1031 from falling out of the storage station 1012 as the bottom material tray 1031 descends; finally, the linear displacement drive 10321 drives the telescopic drive 10322 and the bottom material tray 1031 to move together to the water distribution body loading station 1011, so that the first robot arm 1033 can grip the water distribution body 201.As can be seen, the first feeding mechanism 103 cooperates with the carrier block 1013 through the material tray drive component 1032, which can take out the water separator 201 of one material tray 1031 each time for the first robot arm 1033 to pick up and feed. The remaining material trays 1031 can continue to be stored in the storage rack 1014, which makes it convenient for the staff to place the water separator 201 to be assembled on the material tray 1031 and stack it on the storage rack 1014. This storage action and the action of the first robot arm 1033 feeding the water separator 201 can be carried out simultaneously without interfering with each other, further improving the assembly efficiency.

[0059] The linear displacement drive 10321 can use an existing linear motor module, and the telescopic drive 10322 can use an existing telescopic cylinder.

[0060] See Figure 2 and Figure 3 As shown, Figure 3 The diagram shows a cross-sectional view of the storage rack and tray in the embodiment. Based on the above embodiment, the second end 10132 has a sliding groove 10135, and a limiting post 1015 is welded or integrally connected to the frame 101. The limiting post 1015 slides in conjunction with the sliding groove 10135. This sliding engagement of the limiting post 1015 and the sliding groove 10135 restricts the two rotational limit positions of the first end 10131 and the second end 10132, allowing the first end 10131 to rotate towards the storage station 1012, forming a bearing surface 10134. Furthermore, when the first end 10131 rotates away from the storage station 1012, the guide surface 10133 of the second end 10132 can contact the descending tray 1031.

[0061] See Figure 1 As shown, in one embodiment of the second feeding mechanism 104, the second feeding mechanism 104 includes a vibratory feeder 1041 and a second robotic arm 1042. In this embodiment, the vibratory feeder 1041 of the aforementioned cover 202, connecting rod 203, and fixing ring 205 can be a flexible vibratory feeder. The flexible vibratory feeder can be used in conjunction with an existing CCD vision system to achieve positioning, making it convenient for the second robotic arm 1042 to grasp and feed materials. The vibratory feeder 1041 of the aforementioned bubbler 204, anti-siphon component 206, and filter 207 can be a high-precision vibratory feeder manufactured in Japan, continuously outputting parts one by one. The second robotic arm 1042 can use existing robotic arm equipment, and the second robotic arm 1042 corresponding to different workstations can use different robotic arm equipment.

[0062] like Figure 2 As shown, in this embodiment, the first robotic arm 1033 and the second robotic arm 1042 corresponding to the cover installation station 1021 can share one robotic arm, which can effectively save assembly equipment costs and space.

[0063] like Figure 4 As shown, Figure 4 This is a schematic diagram of the second feeding mechanism corresponding to the bubbler installation station in the embodiment. The second manipulator 1042 of the bubbler can be composed of a chuck 10421, a moving drive component 10422, and a spiral drive component 10423. Both the moving drive component 10422 and the spiral drive component 10423 are mounted on the frame 101. The chuck 10421 is mounted on the output end of the moving drive component 10422. The moving drive component 10422 is used to drive the chuck 10421 to reciprocate toward the bubbler installation station 1023. The chuck 10421 is used to clamp or release the bubbler 204. The spiral drive component 10423 is located on the bubbler installation station 1023 and is used to spirally rotate the bubbler 204. Thus, when assembling the aerator 204, firstly, the vibratory feeder 1041 outputs the aerators 204 one by one, and the chuck 10421 clamps the aerators 204 at the discharge end of the vibratory feeder 1041; then, the moving drive 10422 drives the chuck 10421 and the aerators 204 on it to move to the aerator installation station 1023, so that the aerators 204 are positioned opposite the water separator 201; next, the chuck 10421 releases the aerators 204, and at the same time, the screw drive 10423 screws the aerators 204 onto the corresponding water separator 201; finally, the moving drive 10422 drives the chuck 10421 back to its original position.

[0064] The aforementioned chuck 10421 can use an existing clamping cylinder, the moving drive 10422 can use an existing linear motor module, and the screw drive 10423 can use an existing screwdriver device.

[0065] See Figure 1 , Figure 4 and Figure 5 As shown, Figure 5The diagram shows the structure of the second feeding mechanism corresponding to the fixing ring installation station, the anti-siphon component installation station, and the filter screen installation station in the embodiment. The nozzle semi-automatic assembly machine also includes three positioning detection mechanisms 105 and two depth detection mechanisms 106. The three positioning detection mechanisms 105 and the two depth detection mechanisms 106 are all mounted on the frame 101 and located above the assembly conveyor line 102. One of the positioning detection mechanisms 105 is located between the cap installation station 1021 and the connecting rod installation station 1022, and is used to detect whether the cap 202 is inserted into the center bolt 2011 of the water distribution body 201; another positioning detection mechanism 105 is located between the connecting rod installation station 1022 and the aerator installation station 1023, and is used to detect whether one end of the connecting rod 203 is inserted into a center bolt 2011; a third positioning detection mechanism 105 is located between the fixing ring installation station 1024 and the anti-siphon component installation station 1025, and is used to detect whether the fixing ring 205 is installed on the water distribution body 201. A depth detection mechanism 106 is located between the aerator installation station 1023 and the fixing ring installation station 1024, and is used to detect the screw-in depth of the aerator 204. Another depth detection mechanism 106 is located between the anti-siphon component installation station 1025 and the filter screen installation station 1026, and is used to detect the installation depth of the anti-siphon component 206. Thus, this semi-automatic nozzle assembly machine, through three positioning detection mechanisms 105 and two depth detection mechanisms 106, can monitor the installation status of the cover 202, connecting rod 203, retaining ring 205, aerator 204, and anti-siphon component 206, ensuring that parts are accurately installed in designated positions. If the installation position is incorrect or parts are missing, the machine can promptly alert the operator, thereby significantly improving the nozzle assembly quality.

[0066] The aforementioned positioning detection mechanism can use optical sensors to visually detect whether the installation position of the parts on the water divider is correct, and the aforementioned depth detection mechanism can use displacement sensors.

[0067] See Figure 2 and Figure 4 As shown, the semi-automatic nozzle assembly machine also includes an airtightness testing mechanism 107. The airtightness testing mechanism 107 is installed on the frame 101 and located above the assembly conveyor line 102. The airtightness testing mechanism 107 is located between the bubbler installation station 1023 and the fixing ring installation station 1024. It is used to test the airtightness of the internal passage of the nozzle to ensure the quality of the nozzle leaving the factory.

[0068] The aforementioned airtightness testing mechanism 107 can use an airtightness leak detector. The airtightness testing mechanism 107 can be installed at the next conveying position after the depth testing mechanism 106. In this way, by first measuring the screw-in depth of the bubbler 204 and then measuring the airtightness of the nozzle, the possibility of nozzle leakage due to insufficient installation depth of the bubbler 204 can be ruled out. Furthermore, two or more airtightness testing mechanisms 107 can be provided. Since airtightness testing is time-consuming, having two or more airtightness testing mechanisms 107 simultaneously testing the airtightness can further improve the nozzle assembly efficiency.

[0069] See Figure 1 , Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of the pressing mechanism and the center bolt rotating mechanism located between the cover installation station and the connecting rod plate installation station in the embodiment. Figure 7 The schematic diagram shows the pressing mechanism and the center bolt rotation mechanism located between the connecting rod plate installation station and the bubbler installation station in the embodiment. The nozzle semi-automatic assembly machine also includes two pressing mechanisms 108. One pressing mechanism 108 is located between the cover installation station 1021 and the connecting rod plate installation station 1022, and the other pressing mechanism 108 is located between the connecting rod plate installation station 1022 and the bubbler installation station 1023. The pressing mechanism 108 includes a pressing block 1081 and a pressing block driving member 1082. The pressing block driving member 1082 is mounted on the frame 101 and is connected to the pressing block 1081 in a transmission manner. The pressing block driving member 1082 is used to drive the pressing block 1081 to press down the cover 202 or the connecting rod plate 203. Thus, the pressure block drive 1082 drives the pressure block 1081 to descend, which can press down the cover 202 or the connecting rod plate 203, further ensuring that the cover 202 and the connecting rod plate 203 are assembled in place on the water distribution body 201, and the downward stroke of the pressure block 1081 can be adjusted in advance to ensure the accuracy of the assembly position of the cover 202 and the connecting rod plate 203.

[0070] The pressing mechanism 108 for pressing down the cap 202 can be located at the next conveying position after the positioning detection mechanism 105. In this way, if the positioning detection mechanism 105 detects that the cap 202 is not properly installed, the pressing mechanism 108 will press down the cap 202 again, saving power in the semi-automatic nozzle assembly machine. Alternatively, the pressing mechanism 108 can be located at the previous conveying position of the positioning detection mechanism 105. In this way, the pressing mechanism 108 presses down the caps 202 one by one, and the positioning detection mechanism 105 checks whether the caps 202 are properly installed, ensuring the assembly quality of the nozzles by the semi-automatic nozzle assembly machine. The pressing block drive 1082 can use an existing telescopic cylinder.

[0071] See Figure 1 , Figure 6 and Figure 7As shown, the semi-automatic nozzle assembly machine also includes two center bolt rotation mechanisms 109. One center bolt rotation mechanism 109 is located between the cap mounting station 1021 and the connecting rod mounting station 1022, and is used to rotate the center bolt 2011 for connection of one end of the connecting rod 203. The other center bolt rotation mechanism 109 is located between the connecting rod mounting station 1022 and the aerator mounting station 1023, and is used to rotate the center bolt 2011 to restrain one end of the connecting rod 203 on the center bolt 2011. Thus, the positioning detection mechanism 105 can detect the position of the buckle 202 and the position of the center bolt 2011 at the same time. Both center bolt rotation mechanisms 109 can rotate to adjust the position of the center bolt 2011. The first center bolt rotation mechanism 109 cooperates with the positioning detection mechanism 105 to ensure that the subsequent connecting rod 203 can be connected to the center bolt 2011, while the second center bolt rotation mechanism 109 can restrict the connecting rod 203 to the center bolt 2011 to prevent the connecting rod 203 from falling off.

[0072] The aforementioned center bolt rotation mechanism 109 can be composed of a rotation drive 1091 and a clamping drive 1092. The rotation drive 1091 can use an existing rotation drive motor, and the clamping drive 1092 can use an existing clamping cylinder. Thus, after the clamping drive 1092 clamps the center bolt 2011, the rotation drive 1091 drives the clamping drive 1092 to rotate, thereby causing the center bolt 2011 to rotate.

[0073] See Figure 1 As shown, in one embodiment of the assembly conveyor line 102, the assembly conveyor line 102 includes a first conveyor line 1027, a turntable 1028, a transfer mechanism 110, and a second conveyor line 1029. The first conveyor line 1027, the turntable 1028, the transfer mechanism 110, and the second conveyor line 1029 are all mounted on the frame 101. The cover installation station 1021 and the connecting rod plate installation station 1022 are located on the first conveyor line 1027, the aerator installation station 1023 is located on the turntable 1028, and the fixing ring installation station 1024, the anti-siphon component installation station 1025, and the filter screen installation station 1026 are located on the second conveyor line 1029. The transfer mechanism 110 is used to transfer the water distribution body 201 of the first conveyor line 1027 to the aerator installation station 1023 of the turntable 1028. Thus, the assembly conveyor line 102 consists of a first conveyor line 1027, a turntable 1028, and a second conveyor line 1029, which can avoid excessive conveying length and thus shorten the overall length of the nozzle semi-automatic assembly machine.

[0074] The aforementioned turntable 1028 is driven by a drive mechanism such as a rotary drive motor, thereby rotating and conveying the water distribution body 201.

[0075] like Figure 1As shown, in this embodiment, the transfer mechanism 110 can use a robotic arm to transfer the water distribution body 201, and the transfer mechanism 110 and the second robotic arm 1042 corresponding to the connecting rod plate installation station 1022 can share a robotic arm, which can effectively save assembly equipment costs and space.

[0076] See Figure 4 As shown, at least three clamping members 10281 are welded or screwed onto the turntable 1028. The clamping members 10281 are distributed in a ring at equal intervals and are used to clamp or release the water distribution body 201. Thus, when one clamping member 10281 is positioned opposite the aerator installation station 1023, the other two can be positioned opposite the depth detection mechanism 106 and the airtightness detection mechanism 107, so that the three processes of aerator 204 installation, depth detection, and airtightness detection can be performed simultaneously, further improving the nozzle assembly efficiency.

[0077] The aforementioned clamping member 10281 can use an existing clamping cylinder. Another clamping member 10281 can be added to the aforementioned turntable 1028 to connect with the discharge slide. In this way, when the clamping member 10281 releases the water separator 201, the discharge slide can move the water separator 201 out of the assembly conveyor line 102 so that the staff can manually connect the outer shell 208 and the water separator 201.

[0078] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
