[0004] The purpose of this utility model is achieved as follows: a cotton swab grasping and placing mechanism includes a cotton swab picking and placing component and a swinging component; the cotton swab picking and placing component is provided with a gripper opening and closing cylinder, a gripper, and a gripper mounting seat; the output shaft of the gripper opening and closing cylinder is connected to the gripper and can drive the gripper to open and close to pick up and place cotton swabs; a connecting rod is fixed to the gripper mounting seat; the swinging component includes a swinging rod, a traction rod, a guide rod, and a swinging rod; the swinging rod is hinged to a first bearing that is laterally perpendicular to the mounting plate through its hinged end; the swinging rod is rotatably mounted on the mounting plate through the first bearing; the traction rod has two hinged ends, one of which is connected to a... A first pin, perpendicular to the swing arm, is hinged to the swing arm. The other hinged end is hinged to the swing arm via a second pin, also perpendicular to the swing arm. The hinged end of the guide rod is hinged to the free end of the swing arm via a third pin, perpendicular to the swing arm. The guide rod body is slidably inserted into the longitudinal sliding hole of the connecting rod. The connecting rod is rotatably connected to the free end of the swing arm via a shaft perpendicular to the swing arm. The driving end of the swing arm is driven by a reciprocating cylinder mounted on the mounting plate, causing the swing arm to swing 180° around the pivot, which in turn drives the cotton swab picking and placing assembly to pick up the cotton swabs at the picking station and place them at the packaging station.

[0005] In this invention, the left and right claws of the gripper are respectively connected to a swing base. The gripper is swayably mounted on the gripper mounting base via a pin on the swing base. The swing base is provided with a hook. The output shaft of the gripper opening and closing cylinder is connected to a push-pull block. The push-pull block is provided with a pin that is hinged to the hook. When the gripper opening and closing cylinder pushes the push-pull block, the left and right claws of the gripper swing around the pin through the hinge of the pin and the hook, thereby driving the gripper to open and close.

[0006] In this invention, the first bearing is a deep groove ball bearing.

[0007] In this invention, a second bearing is installed at the free end of the swing rod, and a connecting rod is rotatably mounted on the free end of the swing rod via the second bearing, which is a deep groove ball bearing.

[0008] In this invention, fisheye bearings are provided at both hinged ends of the traction rod and the hinged end of the guide rod.

[0009] The free end is rotatably connected; one traction end of the traction rod is rotatably connected to the swing arm around the Y-axis, and the other traction end of the traction rod is rotatably connected to the rocker arm around the Y-axis; the rocker arm is hinged to the mounting plate through the hinge end, and the rocker arm is allowed to pivot around the Y-axis to swing by the hinge end; the drive end of the swing arm is driven by a reciprocating cylinder mounted on the mounting plate to make the swing arm rotate around the Y-axis and swing 180°, which drives the cotton swab picking and placing assembly to place the cotton swabs at the clamping station from one end of the X-axis to the other end of the X-axis packaging station.

[0010] In this invention, the left and right grippers are respectively connected to a swing base, which is mounted on the gripper mounting base by a pin. The swing base is provided with a hook. The piston rod of the gripper opening and closing cylinder is connected to a push-pull block, which is provided with a pin. The pin is inserted into the hook of the swing base. The piston rod moves back and forth to pull the push-pull block, causing the swing base to swing left and right, thereby controlling the opening and closing actions of the left and right grippers.

[0011] The advantages of this invention are: it only requires a reciprocating cylinder and a gripper opening and closing cylinder for driving; it utilizes a swing guide rod mechanism and a swing traction mechanism, eliminating the need for a sliding lateral movement driving cylinder; and it utilizes its own weight, eliminating the need for a material pressing and moving driving cylinder; therefore, the structure is simpler.

[0018] Reference Figures 1 to 4 This embodiment is a cotton swab grasping and placing mechanism, including a cotton swab picking and placing assembly and a swinging assembly. The cotton swab picking and placing assembly is provided with a gripper opening and closing cylinder 1, a gripper 2, and a gripper mounting base 3. The output shaft of the gripper opening and closing cylinder is connected to the gripper and can drive the gripper to open and close to pick up and place cotton swabs. A connecting rod 4 is fixed on the gripper mounting base. The swinging assembly includes a swing rod 5, a traction rod 6, a guide rod 7, and a swinging rod 8. The swing rod is hinged to a first bearing 9, which is laterally perpendicular to the mounting plate, through its hinged end. The first bearing is a deep groove ball bearing. The swing rod is rotatably mounted on the mounting plate 10 through the first bearing. The traction rod has two hinged ends. One hinged end is hinged to the swing rod through a first pin 11, which is laterally perpendicular to the swing rod, and the other hinged end is hinged to a second pin, which is laterally perpendicular to the swing rod. 12 is hinged to the swing rod, and both hinge ends of the traction rod are provided with fisheye bearings 24; the hinge end of the guide rod is hinged to the free end of the swing rod through a third pin 13 that is transversely perpendicular to the swing rod, and the hinge end of the guide rod is provided with a fisheye bearing. The rod body 14 of the guide rod is slidably inserted into the longitudinal sliding hole of the connecting rod; the connecting rod is rotatably connected to the free end of the swing rod through a rod shaft 15 that is transversely perpendicular to the swing rod, and the free end of the swing rod is equipped with a second bearing 23. The connecting rod is rotatably mounted on the free end of the swing rod through the second bearing, and the second bearing is a deep groove ball bearing; the driving end of the swing rod is driven by a reciprocating cylinder 16 mounted on the mounting plate, which causes the swing rod to swing 180° around the rotating shaft 17, driving the cotton swab picking and placing assembly to pick up the cotton swabs at the picking station and place them at the packaging station.

[0019] In this invention, the left and right claws of the gripper are respectively connected to a swing base 18. The gripper is swayably mounted on the gripper mounting base via a pin 19 of the swing base. The swing base is provided with a hook 20. The output shaft of the gripper opening and closing cylinder is connected to a push-pull block 21. The push-pull block is provided with a pin 22 that is hinged to the hook. When the gripper opening and closing cylinder pushes the push-pull block, the left and right claws of the gripper swing around the pin 22 through the hinge of the pin 22, thereby opening and closing the gripper.

[0020] In this invention, the retraction of the gripper opening and closing cylinder 1 causes the left and right claws of the gripper to clamp the rectangular cotton swab set 25, transforming it into a cylindrical cotton swab set 26. The reciprocating cylinder 16 rotates 180° clockwise, bringing the cylindrical cotton swab set above the bottom-sealing cylinder 27. The extension of the gripper opening and closing cylinder causes the left and right claws to open, allowing the cylindrical cotton swab set to fall into the bottom-sealing cylinder under gravity.
