[0044] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0045] See also Figure 1-Figure 24, an automated production line for a water outlet pipe, comprising a first assembly unit, a second assembly unit and a third assembly unit, which can be arranged adjacent to each other as independent units or combined into an integrated arrangement.

[0046] The first assembly unit includes a first frame 1 and a head shell conveying station 11, a hole position detection station 12, an angle rotation station 13, a plug assembly station 14, an inspection station 15, a defective product collection station 16, and a material unloading station 17 arranged on the first frame 1.

[0047] Among them, the above-mentioned workstations are evenly arranged on the first frame 1 in a circumferential direction, and an area for installing a turntable 18 is formed around it. The turntable 18 is rotatably set on the first frame 1 and is transmission-connected to a first drive unit set in the first frame 1. As one of the options, the first drive unit can be a motor, which is electrically connected to the controller. The controller controls it to drive the turntable 18 to stop after rotating a certain angle, and continue to rotate the set angle after the operation of the corresponding workstation is completed. Of course, when the turntable 18 stops, all workstations can perform corresponding processing actions to improve production efficiency.

[0048] In this embodiment, a plurality of workstations 181 are evenly arranged on the circumference of the turntable 18. The number of workstations 181 is determined according to the number of head shell assembly processes. Figure 2 As shown, there are eight workstations 181, surrounded by seven surrounding stations (including the unloading station), with a blank station reserved between unloading station 17 and the first station. The rotation angle of turntable 18 only needs to ensure that the workstations 181 on turntable 18 can be moved to the next process position after the previous process is completed. If there are eight workstations 181, the turntable 18 rotates 360 / 8 = 45 degrees each time.

[0049] For the head shell conveying station 11, it includes a first vibration plate 111 and a first manipulator 112, wherein the first vibration plate 111 can be placed on the first frame 1 or a bracket can be added to the side of the first frame 1, and the first vibration plate 111 is placed on the bracket. Furthermore, a support frame 113 can be fixed on the first frame 1 to support the discharge guide trough of the first vibration plate 111.

[0050] In this embodiment, a fixed frame 114 is fixed on the first frame 1, and the first manipulator 112 is assembled on the fixed frame 114. As one of the implementation methods, the fixed frame 114 has a linear module for controlling the lateral movement of the first manipulator 112 and a cylinder for controlling the longitudinal movement of the first manipulator 112. The cylinder is assembled on the movable part of the linear module so that the first manipulator 112 can grab the head shell on the discharge guide groove of the first vibration disk 111 to the corresponding work station 181 on the turntable 18.

[0051] For the hole position detection station 12, it includes a first bracket 121 fixed on the first frame 1, a first cylinder 122 fixed on the first bracket 121, a first connecting member 123 fixed on the output end of the first cylinder 122, and a plurality of first detection heads 124 installed on the first connecting member 123. The first detection head 124 is controlled by the first cylinder 122 to move longitudinally.

[0052] In this embodiment, the head shell 2 has a plurality of end corners 21, and the hole 22 of the head shell 2 is opened at one of the end corners 21. Figure 22 As shown, correspondingly, the setting position and setting number of the first detection heads 124 correspond to the number and position of the end angles 21, and all the first detection heads 124 are arranged longitudinally, so that when the first cylinder 122 drives the first detection heads 124 downward, the first detection heads 124 can detect the position of the hole position 22, and feed the signal back to the angle rotation station 13. The angle rotation station 13 relies on the signal to judge and correct the rotation of the head shell 2 to the required angle, that is, the position of the hole position, so as to facilitate the subsequent installation of the plug.

[0053] As for the angle rotation station 13, in this embodiment, it includes a second bracket 131, a second cylinder 132 fixed on the second bracket 131, a second connecting member 133 fixed on the output end of the second cylinder 132, a first rotating cylinder 134 fixed on the second connecting member 133, and a second manipulator 135 installed on the output shaft of the first rotating cylinder 134. The second manipulator 135 is used to rotate the head shell 2 whose angle does not meet the set requirements to the set angle. If the first detection head 124 detects that the angle of the head shell 2 is the same as the set angle, the second manipulator 135 does not move. The second manipulator 135 is specifically controlled by the second cylinder 132 to move up and down, and controlled by the first rotating cylinder 134 to rotate. Of course, it rotates after the second manipulator 135 clamps the head shell.

[0054] As for the plug assembly station 14, in this embodiment, it includes a second vibration plate 141, a third bracket 142, a third cylinder 143 fixed on the third bracket 142, a third connecting member 144 connected to the output end of the third cylinder 143 and driven by the third connecting member 144 for lateral movement, a fourth cylinder 145 fixed on the third bracket 142, and a pressure rod 146 installed on the output end of the fourth cylinder 145.

[0055] Specifically, the second vibration disk 141 can be installed on the first frame 1 or the third bracket 142. The third bracket 142 is fixed on the first frame 1. The third bracket 142 includes a support platform 147. The third connecting member 144 is placed on or slidably connected to the upper surface of the support platform 147. A first hole 148 is provided on the third connecting member 144. Correspondingly, a second hole is provided on the support platform 147. When the first hole 148 and the second hole correspond to each other in upper and lower positions, at least a part of the third connecting member 144 is located at the discharge port of the second vibration disk 141 and blocks the discharge port, so that the plug stays on the upper surface of the third connecting member 144.

[0056] When the third connecting member 144 is driven by the third cylinder 143 to move to the first hole 148 at the discharge port, the plug falls into the first hole 148, and then the third cylinder 143 drives the third connecting member 144 to the first hole 148 corresponding to the second hole above and below, and the plug can fall from the second hole.

[0057] Furthermore, a hollow tube 149 can be fixed on the bottom surface of the support platform 147. The hollow tube 149 corresponds to the second hole and can be concentrically arranged. After passing through the second hole, the plug enters the hollow tube 149 and is guided by the hollow tube 149 to the hole position 22 of the head shell 2. The length of the hollow tube 149 is based on the distance between the second hole and the opening of the hole position 22 of the head shell 2, and can be equal to or slightly less than.

[0058] The pressing rod 146 is located just above the second hole and is controlled by the fourth cylinder 145 to move longitudinally so as to install the plug into the hole 22 of the head shell 2 .

[0059] As for the detection station 15, it includes a fourth bracket 151, a fifth cylinder 152 fixed on the fourth bracket 151, and a second detection head 153 arranged on the output end of the fifth cylinder 152. The fourth bracket 151 is fixed on the first frame 1, and the second detection head 153 is controlled by the fifth cylinder 152 for longitudinal movement. The second detection head 153 is used to detect whether a plug is installed in the hole 22 of the head shell 2.

[0060] For the defective product collection station 16, it includes a fifth bracket 161, a first linear module 162 fixed on the fifth bracket 161, a sixth cylinder 163 installed on the first linear module 162, a third manipulator 164 installed on the output end of the sixth cylinder 163, and a collection tank 165, wherein the fifth bracket 161 is fixed on the first frame 1, the third manipulator 164 is controlled by the first linear module 162 for lateral movement, and by the sixth cylinder 163 for longitudinal movement, and is connected to the second detection head 153 by signal. When the second detection head 153 detects that no plug is installed at the hole 22 of the head shell 2, the controller controls the third manipulator 164 to move to grab the head shell 2 into the collection tank 165, and the collection tank 165 is used to store defective products.

[0061] The qualified head shell 2 is rotated by the turntable 18 and driven to the unloading station 17, which is the next station of the unqualified product collection station 16, and then the head shell 2 is grabbed and taken to the second assembly unit.

[0062] The second assembly unit includes a second frame 3 , on which a head shell grabbing unit 31 , an inner tube conveying unit 32 , a first pressing unit 33 and an outer tube conveying unit 34 are provided. The head shell located at the unloading station 17 is grabbed by the head shell grabbing unit 31 .

[0063] For the head shell grasping unit 31, in this embodiment, it includes a sixth bracket 311, a seventh cylinder 312 fixed on the sixth bracket 311, a second rotating cylinder 313 slidingly connected to the sixth bracket 311 and connected to the output end of the seventh cylinder 312, as well as a fourth manipulator 314, a first transport rail 315, and a fifth manipulator 316.

[0064] Specifically, the sixth bracket 311 is fixed on the second frame 3, and the fourth manipulator 314 is installed at the output end of the second rotary cylinder 313. Since the position of the head shell at the unloading station is relatively low, the fourth manipulator 313 needs to be driven by the seventh cylinder 312 to move longitudinally; and the head shell needs to be changed from longitudinal placement to horizontal placement for the next assembly process, so the fourth manipulator 314 also needs to be driven by the second rotary cylinder 313 to rotate to change the placement state of the head shell.

[0065] The first transport track 315 is provided on the second frame 3 , and a first support platform 317 is slidably connected thereto. The first support platform 317 includes a slot for placing the head shell. When the head shell is placed in the slot, it is in a horizontal arrangement state.

[0066] The first support platform 317 is controlled by a motor or a cylinder to reciprocate on the first transport track 315. After the fourth robot 314 places the head shell on the tank body, the first transport track 315 transports it to the assembly station.

[0067] Furthermore, a seventh bracket 318 is fixed to the second frame 3, a second linear module 319 is installed on the seventh bracket 318, an eighth cylinder 3110 is installed on the second linear module 319, and a fifth manipulator 316 is installed at the output end of the eighth cylinder 3110. The fifth manipulator 316 is controlled by the second linear module 319 for lateral movement and by the eighth cylinder 3110 for longitudinal movement. After the head shell is transported to the assembly station by the first transport rail 315, the fifth manipulator 316 moves to grab it to the assembly position. The assembly position is described in detail below.

[0068] As for the inner tube conveying unit 32 , in this embodiment, it includes a first storage rack 321 , a first push rod 322 for pushing the inner tube 4 out of the first storage rack 321 , a second transport track 323 and a first positioning unit 324 .

[0069] The first storage rack 321 includes an obliquely arranged guide bar 3211 to allow the inner tube 4 to slide down gradually, and at the lower end of the guide bar 3211 there is a accommodating cavity for arranging the inner tubes 4 one by one from bottom to top. The width of the accommodating cavity is adapted to the width of the inner tube 4, and the discharge port is located at the lower end of the accommodating cavity. Therefore, the inner tube 4 can only be pushed out one by one from the discharge port, and the first push rod 322 is used to push the inner tube 4 from the discharge port to the desired position.

[0070] In this embodiment, the first push rod 322 is connected to the ninth cylinder 325 fixed on the first storage rack 321, and is driven by the ninth cylinder 325 to move horizontally. The outer end of the first push rod 322 includes a first notch 3221 that is compatible with the inner tube 4, and the first storage rack 321 is provided with a discharge plate 326 at the discharge port, and the outer end of the discharge plate 326 is provided with a second notch 3261 that is compatible with the inner tube 4. When the first notch 3221 of the first push rod 322 does not correspond to the discharge port, the inner tube at the discharge port cannot fall and is blocked at the discharge port by other parts of the first push rod 322. When the first notch 3221 moves to the discharge port, the inner tube 4 falls into the first notch 3221, thereby leaving the discharge port, and is then brought to the second notch 3261 by the movement of the first push rod 322. When the ninth cylinder 325 pushes the first push rod 322 until the first notch 3221 is connected to the second notch 3261, the inner tube falls from the second notch 3261 onto the second transport track 323.

[0071] The second transport track 323 includes a conveyor belt that moves back and forth in a circular motion and several groups of second support platforms arranged on the conveyor belt. As one embodiment, the second support platforms are arranged on the left and right sides of the conveyor belt and include open grooves for accommodating the inner tube 4, thereby supporting and positioning the inner tube 4 and transporting it to the assembly position by the conveyor belt.

[0072] The first positioning unit 324 is located at the assembly position, which includes a tenth cylinder fixed on the second frame 3 and a first baffle arranged on the tenth cylinder. The first baffle is controlled by the tenth cylinder to move laterally. As mentioned above, when the fifth manipulator 316 grabs the head shell 2 to the assembly position, and the corresponding inner tube 4 is driven to the assembly position and stops (the conveyor belt is temporarily stopped by the controller, and the specific design can be referred to the existing design, such as setting sensors, etc.), the first baffle is driven to one end of the inner tube 4 to limit the inner tube 4.

[0073] Furthermore, the first clamping unit 33 includes an eleventh cylinder fixed on the second frame 3 and a first pushing head 331 installed at the output end of the eleventh cylinder. As described above, after the head shell 2 and the inner tube 4 are moved into place and the inner tube 4 is limited by the first baffle, the eleventh cylinder drives the first pushing head 331 to move horizontally to install the head shell 2 into one end of the inner tube 4. During the installation process, the inner tube 4 is supported by the first baffle to ensure that the head shell 2 and the inner tube 4 are reliably connected.

[0074] As for the outer tube conveying unit 34, in this embodiment, it includes a second storage rack 341, a discharge channel 342 arranged at the discharge port of the second storage rack 341, a second positioning unit 343 for limiting the inner tube 4, and a second pushing head 344 for fitting the outer tube 5 onto the inner tube 4.

[0075] The structure of the second storage rack 341 is the same as or similar to that of the first storage rack 321 , and for details, reference may be made to the above description of the first storage rack 321 .

[0076] After the outer tubes are arranged one by one from top to bottom in the second storage rack 341 , the lowest outer tube falls into the discharge channel 342 . The shape and width of the concave portion of the discharge channel 342 are adapted to the shape and size of the outer tubes.

[0077] The second pushing head 344 is connected to the third linear module 345 provided on the second frame 3 and is driven by the third linear module 345 to move linearly back and forth. The upper end of the second pushing head 344 is arranged at the discharge channel 342 to push the outer tube 5 to move horizontally. Figure 14 As shown, the discharge channel 342 is formed by two rods with a gap. The gap between the two rods forms an opening at the bottom of the discharge channel for the second pushing head 344 to enter and move back and forth to push the outer tube 5 forward and return to its original position. The upper ends of the two rods are fixedly mounted on the second storage rack 341.

[0078] The second positioning unit 343 includes an eighth bracket 346 fixed on the second frame 3, a fourth linear module 347 arranged on the eighth bracket 346, a fourth connecting member 348 arranged at the output end of the fourth linear module 347, and a plurality of eighth manipulators 349 arranged on the fourth connecting member 348.

[0079] In this embodiment, there are two eighth manipulators 349, which are respectively installed at the two ends of the fourth connecting member 348. When the semi-finished product after the head shell 2 and the inner tube 4 are assembled is transported to the second positioning unit 343 via the second transport track 323, the two eighth manipulators 349 respectively clamp the two ends of the semi-finished product, and the second pushing head 344 and other structures are located opposite the second positioning unit 343. After the semi-finished product is positioned, the second pushing head 344 pushes the outer tube 5 horizontally, and the outer tube 5 is mounted on the outside of the inner tube 4, and one end of the outer tube 5 extends to the head shell 2 to form a component assembled into one piece by the head shell 2, the inner tube 4 and the outer tube 5.

[0080] The third assembly unit includes a third frame 6 , on which a first insert conveying unit 61 , a second insert conveying unit 62 and a second pressing unit 63 are provided.

[0081] In this embodiment, a third transport track 64 is provided on the third frame 6. The third transport track 64 includes a conveyor belt that moves back and forth in a circular motion and several groups of third support platforms arranged on the conveyor belt. The third transport track 64 can have the same or similar structure as the second transport track 323, or the two themselves are the same component assembled into one. The relevant specific structure can refer to the structural description of the second transport track.

[0082] For the first insert conveying unit 61, it includes a second vibration plate 611, a sixth manipulator 612 for mounting the first insert 71 on the outer tube 5, and a first driving member installed on the third frame 6. The sixth manipulator 612 is driven by the first driving member. The first driving member can control the longitudinal and lateral movements of the sixth manipulator 612, such as a driving component composed of a linear module and a cylinder similar to the above.

[0083] As for the second insert conveying unit 62, it includes a third vibration plate 621, a seventh robot 622 for mounting the second insert 72 on the outer tube 5, and a second driving member installed on the third frame 6. The seventh robot 622 is driven by the second driving member. The second driving member can control the longitudinal and lateral movements of the seventh robot 622, such as a driving component composed of a linear module and a cylinder similar to the above.

[0084] When the semi-finished product composed of the head shell 2, the inner tube 4 and the outer tube 5 is assembled into one, it is driven by the conveyor belt to the first insert conveying unit 61, and the sixth robot 612 puts the first insert 71 at the discharge port of the second vibration disk 611 on the outer tube 5; and then the semi-finished product is driven by the conveyor belt to the second insert conveying unit 62, and the seventh robot 622 puts the second insert 72 at the discharge port of the third vibration disk 621 on the outer tube 5. For the conveyor belt to stop after reaching the corresponding workstation and continue the action after the operation is completed, you can refer to the existing design, such as setting sensors.

[0085] Because the outer tube 5 has a certain length, the robot arm cannot directly push the first insert 71 and the second insert 72 to the position of the head shell 2 at the other end. For this reason, it is necessary to operate by setting a second clamping unit 63. Specifically, the second clamping unit 63 includes a fifth linear module 631, a rod 632 driven by the fifth linear module 631 for horizontal movement, and a pressing plate 633 fixed to the outer end of the rod 632. The rod 632 is driven to move horizontally by the fifth linear module 631, and the pressing plate 633 moves horizontally accordingly. During the movement, the first insert 71 and the second insert 72 are pushed and pressed into the head shell 2.

[0086] The pressing piece 633 may include an opening 6331 that matches the shape of the outer tube 5. When the pressing piece 633 is working, the outer tube 5 is located in the opening 6331, so that the pressing piece 633 can smoothly push the first insert 71 and the second insert 72 mounted on the outer tube 5.

[0087] The process of assembling water outlet pipes on the automated production line includes the following steps: S1. Sort the head shells through the vibration disk and transfer them to the first workstation on the turntable; S2. Check the orientation of the holes on the head shell. If the orientation of the holes does not match the setting, adjust the orientation of the holes by rotating the head shell; S3. Insert the plug into the hole; S4. Check whether the plug is installed in place. If not, grab the head shell and put it into the unqualified product collection tank; S5. Adjust the head shell from a longitudinal arrangement to a transverse arrangement and transfer it to a suitable workstation; S6. Assemble the head shell and the inner tube into one; S7. Put the outer tube on the inner tube; S8. Put the first insert and the second insert on the outer tube; S9. Push the first insert and the second insert into the head shell.
