[0002] In the production process of water guns, the various parts and the main body of the water gun are first prepared, and then the parts are assembled into the main body to form a complete product. Currently, water gun assembly mainly relies on manual operation by employees, using simple jigs to fit O-rings and press-fitting fixtures. The specific steps for manual assembly of a water gun include: manually removing the main body, manually fitting the first set of O-rings, manually installing the protective sleeve, manually placing the adjusting nut, and manually pressing in the second set of O-rings.

[0038] Example 2: This invention provides a method for using a fully automatic water gun assembly machine, employing the fully automatic water gun assembly machine of Example 1. The assembly method includes the following steps: The first step is that the feeding group starts to vibrate and feed the water gun body, two sets of O-rings, sheaths and adjusting nuts in sequence. The first vibrating feeding platform 2, the second vibrating feeding platform 3, the third vibrating feeding platform 4, the fourth vibrating feeding platform 5 and the fifth vibrating feeding platform 6 respectively vibrate and feed the water gun body, the first set of O-rings, the sheath, the adjusting nut and the second set of O-rings. In the second step, the water gun body is gripped and installed at the first rotating worktable 101 by the first assembly mechanism 7. The water gun body, which is fed along the first vibrating loading platform 2, is guided by the first guide box 702 to one end near the first placement platform 703. At this time, through the cooperation of the first horizontal push cylinder 705 and the first vertical push cylinder 707, the first gripper cylinder 709 is first positioned above the first guide box 702. After the first gripper cylinder 709 outputs and grips the water gun body, it is then moved to the first rotating worktable 101 by the cooperation of the first horizontal push cylinder 705 and the first vertical push cylinder 707, and the water gun body is clamped into the insertion hole of the first rotating worktable 101. In the third step, the first rotating worktable 101 rotates the worktable with the assembled water gun body to the second assembly mechanism 8. The second assembly mechanism 8 uses a ring fitting method to fit the first set of O-rings onto the water gun body. The first rotating worktable 101 rotates counterclockwise (from the top view of the whole machine) to rotate the insertion hole of the water gun body to above the docking seat 809. Before this, the first set of O-rings has been guided by the second guide box 803 and, under the obstruction of the first blocking cylinder 804, by the second horizontal pushing cylinder 805 and the second vertical pushing cylinder 807. With the cooperation of the material grabbing cylinder 806, the first set of O-rings blocked by the first blocking cylinder 804 is grabbed. Then, the material grabbing cylinder 806 transfers the grabbed first set of O-rings to the top of the docking seat 809. Under the output control of the third horizontal push cylinder 808, the docking seat 809 is transferred to the bottom of the first rotating station 101. Finally, the second vertical push cylinder 807 outputs upward to attach the first set of O-rings to the outer wall of the water gun body. In the fourth step, when the pistol body equipped with the first set of O-rings is transferred to the junction of the first rotating worktable 101 and the second rotating worktable 102, it is located at the third assembly mechanism 9. The third assembly mechanism 9 presses the sheath onto the outer wall of the pistol body. The water gun body equipped with the first set of O-rings continues to be transferred along with the rotation of the first rotating worktable 101. After that, it is transferred to the bottom of the fourth gripper cylinder 1206. With the cooperation of the eighth horizontal push cylinder 1203 and the sixth vertical push cylinder 1205, the water gun body equipped with the first set of O-rings is gripped and placed into the insertion hole of the second rotating worktable 102, and rotates clockwise with the second rotating worktable 102 (from the top view of the whole machine). The sheath, fed from the third vibrating feeding platform at point 4, is transferred along the third guide box 903 to one end near the second blocking cylinder 909 and blocked by the baffle 910. Then, with the cooperation of the fourth horizontal push cylinder 904 and the third vertical push cylinder 906, the second gripper cylinder 908 is driven to grab the sheath. Then, the fourth horizontal push cylinder 904 and the third vertical push cylinder 906 move the gripper cylinder 908 above the second rotating station 102. After the sheath is aligned with the water gun body, the third vertical push cylinder 906 outputs downward to press the sheath against the outer wall of the water gun body.

[0039] Fifth step: The water gun body with the sheath assembled is rotated and moved from the second rotating worktable 102 to the fourth assembly mechanism 10. The fourth assembly mechanism 10 screws the adjusting nut onto the outer wall of the water gun body. After the sheath is pressed, the water gun body is transferred to the top of the torsion sleeve 1015 by the transfer of the second rotating worktable 102. Before this, the adjusting nut fed by the fourth vibrating feeding table 5 is first guided by the fourth guide box 1002 to one end near the third gripper cylinder 1008, where it is gripped by the third gripper cylinder 1008. Then the fifth horizontal push cylinder 1005 is activated, and under the sliding support guidance of the guide plate 1006 and the rotating support 1007, the water gun body is moved to the top of the torsion sleeve 1015. After the third gripper cylinder 1008 rotates 90 degrees, it grips the adjusting nut vertically downwards. Then, with the cooperation of the fourth vertical push cylinder 1010 and the sixth horizontal push cylinder 1012, the adjusting nut is clamped on the top of the torsion sleeve 1015. Then, the output of the sixth horizontal push cylinder 1012 transfers the torsion sleeve 1015 with the adjusting nut to the bottom of the second rotating worktable 102. When the water gun body with the protective sleeve installed moves above the torsion sleeve 1015, the output of the fourth vertical push cylinder 1010 is started, and with the output of the torsion motor 1014, the torsion sleeve 1015 moves upward and rotates at the same time, thereby screwing and fitting the adjusting nut onto the outer wall of the water gun body. Step 6: The water gun body with the adjusting nut assembled continues to rotate and be conveyed along the second rotating worktable 102 to the fifth assembly mechanism 11. The fifth assembly mechanism 11 installs the second set of O-rings onto the water gun body. The water gun body with the assembled and adjusting nut continues to move along the second rotating worktable 102 to below the output of the downward push cylinder 1108. Before this, the second set of O-rings at the fifth vibrating loading table 6 is blocked by the alignment cylinder 1109. The seventh horizontal push cylinder 1104 and With the cooperation of the fifth vertical push cylinder 1106, the material-grabbing structure of the lower push cylinder 1108 grabs the second set of O-rings. Then, under the output of the seventh horizontal push cylinder 1104, the material-grabbing structure of the lower push cylinder 1108 that grabbed the second set of O-rings is transferred to the top of the second rotating worktable 102. After the water gun body is in place, the fifth vertical push cylinder 1106 cooperates with the lower push cylinder 1108 to press the second set of O-rings onto the outer wall of the water gun body. At this time, the assembly of all parts and the water gun body is completed. Afterwards, the assembled water gun continues to rotate with the second rotating worktable 102. With the cooperation of the ninth horizontal push cylinder 1304 and the seventh vertical push cylinder 1306, the fifth gripper cylinder 1307 grabs the assembled water gun, and then the ninth horizontal push cylinder 1304 and the seventh vertical push cylinder 1306 work together to transfer it out of the second rotating worktable 102. Afterwards, the assembled water gun falls to the unloading guide plate 1308 for guidance and discharge.
