Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 2 As shown, the embodiment of the present invention proposes a rotation positioning and picking mechanism for the production of ready-to-use caps, comprising a base 1, a lifting cylinder 2, a rotating device 3, a swing arm 4 and a plurality of picking devices 5, wherein:

[0033] The lifting cylinder 2 is mounted on the base 1, and its output shaft is connected to the rotating device 3;

[0034] The rotating device 3 is connected to the swing arm 4 and is used to drive the swing arm 4 to rotate;

[0035] A plurality of the picking devices 5 are installed on the swing arm 4 at intervals;

[0036] The swing arm 4 drives the picking device 5 to switch between the first state and the second state under the drive of the rotating device 3:

[0037] In the first state, the picking device 5 is aligned with a first placement hole for placing the ready-to-match cap on a workstation of the assembly line;

[0038] In the second state, the picking device 5 is aligned with a second placement hole for placing the ready-to-match caps on the workstation of the conveyor line.

[0039] It should be noted that the first state is the initial state. The picking device 5 picks up the ready-to-match cap from the workstation on the assembly line, and the rotating device 3 drives the swing arm 4 to rotate forward at a fixed angle (90 degrees in this embodiment, and the angle can be set according to actual conditions), so that the picking device 5 is in the second state. After the picking device 5 places the ready-to-match cap on the workstation on the conveyor line, the rotating device 3 drives the swing arm 4 to return to the first state.

[0040] The rotating positioning pickup mechanism for on-demand cap production provided in this embodiment, in the first state, the pickup device 5 is aligned with the first placement hole on the work station of the assembly line for placing the on-demand cap, the lifting cylinder 2 drives the rotating device 3 and the swing arm 4 to descend, the pickup device 5 picks up the on-demand cap, the lifting cylinder 2 drives the rotating device 3 to ascend, the rotating device 3 drives the pickup device 5 to rotate to the second state, the lifting cylinder 2 drives the rotating device 3 to descend, the pickup device 5 releases the on-demand cap, and the on-demand cap reaches the second placement hole on the work station of the conveying line for placing the on-demand cap; through the joint action of the lifting cylinder 2 and the rotating device 3, the swing arm 4 can simultaneously make precise lifting and rotating actions, cooperate with the pickup of the pickup device 5, realize the pickup and transfer of the on-demand cap, and one time can pick up multiple on-demand caps, which can ensure accuracy and improve efficiency.

[0041] In some embodiments, the rotating positioning pickup mechanism further comprises a rotating shaft 6, which is connected with the rotating device 3 and the swing arm 4 respectively, the rotating shaft 6 is coaxial with the output shaft of the rotating device 3, and the swing arm 4 is perpendicular to the axis of the rotating shaft 6. Through the connection of the rotating shaft 6 with the rotating device 3 and the swing arm 4 respectively, the rotating shaft 6 is coaxial with the output shaft of the rotating device 3, and the swing arm 4 is perpendicular to the axis of the rotating shaft 6; the rotating shaft 6 can pull apart the distance between the swing arm 4 and the rotating device 3, so that there is enough space below the swing arm 4 to install the pickup device 5, which is convenient for the placement of the pickup device 5, so that the swing arm 4 will not be disturbed when swinging, and the reliability of the device is improved.

[0042] In some embodiments, the rotating positioning pickup mechanism further comprises a connecting plate 7 and at least two guide columns 8; the connecting plate 7 is connected with the top of the lifting cylinder 2, and at least two mounting holes are arranged on the connecting plate 7; one end of the guide column 8 is slidingly installed in the mounting hole, and the other end is connected with the rotating cylinder. Two mounting holes can be arranged at opposite corners of the connecting plate 7, which can reduce the space occupation, so that the size of the connecting plate 7 can be smaller. Through the connection of the connecting plate 7 with the top of the lifting cylinder 2, at least two mounting holes are arranged on the connecting plate 7; one end of the guide column 8 is slidingly installed in the mounting hole, and the other end is connected with the rotating cylinder; the guide column 8 guides the lifting of the rotating cylinder, improves the stability of the lifting, and avoids that the upper parts are too heavy to cause the output shaft of the lifting cylinder 2 to be subjected to too large bending moment, which affects the lifting of the output shaft of the lifting cylinder 2, and improves the reliability of the device.

[0043] In some embodiments, the rotation positioning pickup mechanism further includes at least two sliding bearings 9, the sliding bearings 9 being installed in the mounting holes, and the guide column 8 being installed in the sliding bearings 9. With the sliding bearings 9 installed in the mounting holes and the guide column 8 installed in the sliding bearings 9, the guide column 8 can be more stable and have better guidance when sliding in the sliding bearings 9, thereby improving the reliability and stability of the device.

[0044] In some embodiments, the rotation positioning and picking mechanism further includes a limit post 10, which is mounted on the connecting plate 7 and parallel to the guide post 8. The height of the limit post 10 exposed above the connecting plate 7 is greater than the height of the sliding bearing 9 exposed above the connecting plate 7. By mounting the limit post 10 on the connecting plate 7 and being parallel to the guide post 8, and the height of the limit post 10 exposed above the connecting plate 7 being greater than the height of the sliding bearing 9 exposed above the connecting plate 7, the lifting cylinder 2 can be prevented from driving the rotating device 3 to descend beyond a limit and contacting the sliding bearing 9, thereby preventing the rotating device 3 from being damaged by the force exerted by the contact with the sliding bearing 9 and thereby improving the service life of the device.

[0045] In some embodiments, the rotation positioning and picking mechanism further includes a buffer pad 11, which is mounted on the top of the limiting post 10. By providing the buffer pad 11 on the top of the limiting post 10, the rotating device 3 can be cushioned when it contacts the limiting post 10, thereby preventing the limiting post 10 from applying excessive force to the rotating device 3 locally and damaging the rotating device 3, thereby increasing the service life of the rotating device 3.

[0046] In some embodiments, the rotating device 3 utilizes a rotary cylinder. A rotary cylinder is a pneumatic actuator that oscillates back and forth within an angular range of less than 360°. It utilizes compressed air to drive an output shaft to reciprocate within a certain angular range. In this embodiment, the rotating device 3 utilizes a rotary cylinder to drive the rotating shaft 6 to reciprocate.

[0047] In some embodiments, the rotating device 3 is a motor. The rotating device 3 can be a motor, which is a servo motor. By controlling the forward rotation, reverse rotation and speed of the motor, the rotating shaft 6 is rotated at a certain angle and reset, thereby realizing the switching between the first state and the second state.

[0048] In some embodiments, the output shaft of the rotating device 3 is coaxial with the output shaft of the lifting cylinder 2. By arranging the output shaft of the rotating device 3 coaxial with the output shaft of the lifting cylinder 2, the rotation of the rotating shaft 6 can be prevented from generating torque on the output shaft of the lifting cylinder 2, thereby making the lifting and lowering of the output shaft of the lifting cylinder 2 smoother and improving reliability.

[0049] In some embodiments, the pickup device 5 adopts a vacuum chuck. The vacuum chuck is connected with an air pump through an air pipe. The pickup device 5 adopts the vacuum chuck, so that the adsorption performance can be improved. After contacting with the top of the ready-to-use cap, the air pump is used to pump air, and the vacuum chuck forms a negative pressure to adsorb the ready-to-use cap. When the ready-to-use cap needs to be released, the air pump is used to inflate, the negative pressure of the vacuum chuck disappears, and the cap can be automatically released under the action of gravity.

[0050] The working principle of the rotating positioning pickup mechanism for the ready-to-use cap production of the embodiment is as follows: in the initial state, the two vacuum chucks are opposite to the first placing holes of the two ready-to-use caps on the lower assembly line, the lifting cylinder 2 drives the rotating device 3 and the swing arm 4 to move downward, the vacuum chucks contact the top of the ready-to-use cap to generate a negative pressure, the vacuum chucks adsorb the ready-to-use cap, then the lifting cylinder 2 drives the rotating device 3 and the swing arm 4 to move upward, the rotating cylinder drives the swing arm 4 to rotate by 90 degrees, then the lifting cylinder 2 drives the rotating device 3 and the swing arm 4 to move downward, the vacuum chucks lose the negative pressure, the ready-to-use cap is separated from the vacuum chucks and falls into the second placing holes of the two ready-to-use caps on the conveying line, then the lifting cylinder 2 drives the rotating device 3 and the swing arm 4 to move upward, the rotating cylinder drives the swing arm 4 to rotate by 90 degrees in the opposite direction, and the swing arm 4 is reset to the initial state, so that the automatic grabbing and transferring of the ready-to-use cap from the assembly line to the conveying line are realized.

[0051] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
