[0019] Specific Implementation Example 1: Please refer to Figures 1-4 An automatic bottle cap screwing device is used to screw the bottle cap 1 to the mouth of the bottle body 2, and includes a limiting turntable 3, a screwing component 4 and a positioning component 5.

[0020] The bottle cap 1 is placed on the mouth of the bottle body 2. It should be noted that in this embodiment, the method of clamping the bottle cap 1 to the mouth of the bottle is not limited. Using a robotic arm to clamp the bottle cap 1 is a conventional existing technical means. Its specific connection relationship and working principle will not be described here.

[0021] Several bottles 2 are sequentially snapped onto the outer edge of the limiting turntable 3, with the upper end of the bottle mouth extending above the limiting turntable 3, and the lower side of the bottle cap 1 being higher than the upper side of the limiting turntable 3. The limiting turntable 3 has the ability to rotate.

[0022] The limiting turntable 3 has several limiting grooves 31 evenly distributed around its circumference. The inner diameter of the limiting grooves 31 matches the outer diameter of the bottle mouth, and the bottle body 2 is snapped into the limiting grooves 31. The electric rotating shaft 32 is embedded in the center of the limiting turntable 3, and one end of the electric rotating shaft 32 is fixedly connected to the output end of an external motor to drive the limiting turntable 3 to rotate around its axis.

[0023] The positioning assembly 5 includes a positioning gripper 51, a positioning plate 53, and a translation cylinder. At least one positioning gripper 51 is disposed on the outer side of the limiting turntable 3, and the positioning gripper 51 moves in a directional manner to abut against the outer side of the bottle cap 1. The screwing assembly 4 is disposed after the positioning assembly 5 and is used to screw the bottle cap 1. The positioning plate 53 is fixedly connected to the positioning gripper 51, and the output end of the translation cylinder is fixedly connected to one end of the positioning plate 53 to drive the positioning gripper 51 to translate. The positioning gripper 51 has a positioning groove 52, the opening of which faces the bottle cap 1, and the positioning groove 52 includes an arc-shaped sidewall that matches the outer diameter of the bottle cap 1.

[0024] In another feasible embodiment, such as Figure 1 As shown, it includes two sets of positioning components 5. The two sets of positioning components 5 are arranged perpendicularly to each other, and the positioning claws 51 of the positioning components 5 are all facing the bottle cap 1, so that the arc-shaped sidewall can abut against the outside of the bottle cap 1.

[0025] In this embodiment, the tightening assembly 4 includes a tightening cap 41, a tightening shaft 44, and a lifting cylinder. The upper side of the tightening cap 41 is fixedly connected to the lower end of the tightening shaft 44, and the tightening shaft 44 is fixedly connected to the output end of an external rotating motor to drive the tightening cap 41 to apply torque. The lifting cylinder is disposed on the upper side of the tightening shaft 44 and is connected to the tightening shaft 44 to drive the tightening shaft 44 to move up and down. The lifting cylinder driving the tightening shaft 44 to move up and down is a conventional existing technology, and its specific connection relationship and working principle will not be described in detail here.

[0026] Preferably, when the bottle cap 1 is tightened, the tightening cap 41 and the bottle cap 1 are located on the same axis.

[0027] The tightening cap 41 has a tightening groove 42 inside, and the side wall of the tightening groove 42 is knurled. The inner diameter of the tightening groove 42 matches the outer diameter of the bottle cap 1. A guide ring 43 is fixedly installed on the upper side of the tightening groove 42, and the distance between the guide ring 43 and the lower side of the tightening groove 42 is equal to the height of the bottle cap 1.

[0028] Working principle:

[0029] When it is necessary to turn the bottle cap 1, the bottle body 2 with the bottle cap 1 is rotated to the positioning component 5. The positioning claw 51 moves directionally toward the bottle cap 1. The arc-shaped sidewall of the positioning groove 52 of the positioning claw 51 abuts against the outer side of the bottle cap 1, pushing the bottle cap 1 to adjust its direction. After the direction adjustment is completed, the bottle cap 1 rotates toward the screwing component 4. The lifting cylinder drives the tightening shaft 44 to move downward, and the bottle cap 1 is screwed through the tightening cap 41. This can realize the positioning adjustment of the bottle cap 1 placed on the bottle body at an angle, so that the bottle cap 1 is accurately placed at the center of the bottle mouth, thereby improving the accuracy and stability of the alignment of the bottle cap 1 and improving the quality of the screwing of the bottle cap 1.
