[0012] (2) The handle box on the lifting slide table descends to the position for installing the handle, and the bottle and the handle rotate synchronously;

[0013] (3) After the upper and lower push rods on the handle box touch the upper and lower cams respectively and successively, the handle is installed on the bottle by simulating manual actions.

[0014] As a preferred solution, after step (3), the bottle with the handle installed is rotated to the handle detection station, and the handle detection mechanism is used to detect the stability of the handle installation.

[0015] As a preferred solution, when the handle touches the lever of the handle detection mechanism, if the handle is not installed properly, the handle will fall off, and if it is qualified, the handle will not fall off.

[0016] As a preferred solution, when the bottle reaches the conveyor through the bottle discharge star wheel, if the bottle with the handle fallen off is detected by the rejection mechanism, it will be rejected from the conveyor to separate it from the qualified products.

It should be understood that the specific embodiments described here are only for the purpose of illustrating and explaining the present invention and are not used to limit the present invention.

[0028] As Figures 1 to 5As shown in the figure, an upper handle mounting machine in this embodiment includes a bottle feeding screw 1, a bottle feeding star wheel 2, a main turntable 3, a bottom support 4, a bottle turning and positioning mechanism 5, a lifting slide 6, a handle box 7, an upper handle cam 8, and a handle detection mechanism 9. The bottle feeding screw 1 is arranged on one side of the bottle feeding star wheel 2. The main turntable 3 is arranged on the side of the bottle feeding star wheel 2. The bottom support 4 is arranged on the main turntable 3. The bottle turning and positioning mechanism 5 is arranged on the side of the bottle feeding star wheel 2. The lifting slide 6 is arranged above the main turntable 3. The handle box 7 is arranged below the lifting slide 6. The upper handle cam 6 and the handle detection mechanism 9 are arranged on the side of the main turntable 3. In the above technical solution, the bottle 10 is sent by the bottle feeding screw 1 and the bottle feeding star wheel 2 to the bottom support 4 of the main turntable 3, and then the bottle is positioned by the bottle turning and positioning mechanism 5. The handle box 7 on the lifting slide 6 descends to the position for installing the handle. The bottle 10 and the handle 11 rotate synchronously. When the upper and lower push rods on the handle box 7 touch the upper and lower cams respectively in sequence, the handle is installed on the bottle by simulating the manual operation. When the bottle with the handle installed rotates to the handle detection station, the handle is detected by the handle detection mechanism 9. Through the above technical solution, when installing the handle, the handle and the bottle move synchronously, which prolongs the positioning and installation time and improves the qualified rate.

[0029] In this embodiment, the detection mechanism 9 includes a lever 91, a rotating shaft 92, and a servo motor 93. The lever 91 is arranged on the rotating shaft 92. The rotating shaft 92 and the servo motor 93 are connected by a synchronous belt 94. Through the above technical solution, when the handle 11 touches the lever 91, if the handle is not installed qualifiedly, the handle will fall off; if it is qualified, the handle will not fall off. The servo motor and the lever can be adjusted to an appropriate torque according to requirements. There are multiple levers 91, and the multiple levers 91 are arranged at intervals, so that when the rotating shaft 92 rotates, the levers can contact the handle in sequence. The rotating shaft 92 is arranged on a base 95 and is supported by the base 95. The upper handle mounting machine includes a conveyor 12 and a bottle discharging star wheel 13. The conveyor 12 is arranged on the side of the bottle discharging star wheel 13. The bottle discharging star wheel 13 is arranged opposite to the bottle feeding star wheel 2. Through the above technical solution, the bottle enters from one end, rotates and then exits from the other end, and the input and output paths are in opposite directions.

[0030] A handle installation method includes the following steps: (1) The bottle 10 is sent by the bottle feeding screw 1 and the bottle feeding star wheel 2 to the bottom support 4 of the main turntable 3, and then the bottle is positioned by the bottle turning and positioning mechanism 5; (2) The handle box 7 on the lifting slide 6 descends to the position for installing the handle, and the bottle and the handle 11 rotate synchronously; (3) When the upper and lower push rods on the handle box 7 touch the upper and lower cams respectively in sequence, the handle 11 is installed on the bottle 10 by simulating the manual operation.

[0031] After step (3), the bottle 10 with the handle installed rotates to the handle detection station, and the handle installation stability is detected by the handle detection mechanism 9.

[0032] When the handle 11 touches the lever 91 of the handle detection mechanism 9, if the handle is not properly installed, the handle will fall off; if it is properly installed, the handle will not fall off.

[0033] When the bottle reaches the conveyor 12 via the bottle outlet star wheel 13, if the handle of the bottle has fallen off, the rejection mechanism will detect it and reject it from the conveyor 12, separating it from the qualified products.

[0034] An upper handle machine and an upper handle method according to this embodiment can make the handle move synchronously with the bottle when installing the handle, extend the positioning and installation time, and improve the qualification rate; at the same time, it can conveniently detect the installation effect of the handle and ensure the installation quality.
