A push pen and its processing method

Abstract

The present invention discloses a push-button fountain pen and a processing method thereof, and relates to the field of fountain pen processing and conveying technology. The pen comprises a pen case, one end of which is plugged with a first movable sleeve. The assembled pen parts are conveyed to a packaging location via a conveying mechanism. The present invention provides a conveying mechanism, and when a telescopic cylinder is extended, a special-shaped guide rail moves toward a positioning column. At this time, a second movable pin first moves upward and then downward under the extrusion and guidance of the special-shaped guide rail. If the pen head faces the connecting shaft and the pen cannot fall into a U-shaped receiving trough, as the telescopic cylinder continues to extend, the worm gear drives the turntable to rotate 180 degrees. Then, the telescopic cylinder contracts, causing one side of the turntable to tilt, thereby causing the pen to fall into the inner side of the U-shaped receiving trough. Then, the motor drives the U-shaped receiving trough to rotate clockwise, causing the pen to fall onto a conveyor. In this way, the orientation of the pen can be uniformly processed during the conveying process.

The rotatable connection is provided with a positioning block 820, a turntable 808 is installed on the top of the positioning block 820, a placement slot 809 is provided on the top of the turntable 808, the pen is placed on the inner side of the placement slot 809, and blocking pins 812 are inserted at both ends of the top of the placement slot 809. A second telescopic spring 811 connected to the blocking pin 812 is provided on the top of the placement slot 809, and a guide roller 810 is installed on the inner side of the placement slot 809. The bottom of the turntable 808 is rotatably connected to the positioning ring 807 through a bearing, and a connecting guide rail 821 is installed on the bottom of the positioning ring 807. The inner side of the guide rail 821 is slidably connected with a first movable pin 822, and a plug rod 823 is provided on the first movable pin 822. A guide plate 813 connected to the positioning column 805 is provided on the outer side of the plug rod 823. A second movable pin 824 is installed at the bottom end of the plug rod 823. A side connecting frame 815 is installed on the side of the positioning column 805 away from the guide plate 813. A worm gear 819 is provided on the rotating column 806. The top of the side connecting frame 815 is rotatably connected to a worm 817 that meshes with the worm gear 819 through a rotating shaft. The two ends of the worm gear 817 are rotatably connected to the disc 828, a second transmission spur gear 827 is installed at one end of the disc 828 away from the worm 817, and ratchet wheels 826 are installed on the outer sides of both ends of the worm 817. A pawl 829 meshing with the ratchet wheel 826 is provided on one side of the disc 828 away from the second transmission spur gear 827, and a torsion spring is connected to the connection between the pawl 829 and the disc 828 through a slot. The output end of the telescopic cylinder 804 is connected to the special-shaped guide rail 814, and a support rod 816 is installed on the top of the special-shaped guide rail 814, and a shift rack 825 is provided on the top of the support rod 816.

[0045] In this embodiment, after the pen is assembled by the assembly machine, the assembled pen is transported to the inner side of the placement slot 809 by the conveyor belt, and then the telescopic cylinder 804 is controlled by the external controller to perform a telescopic operation. When the telescopic cylinder 804 is extended, the special-shaped guide rail 814 will move toward the positioning column 805. At this time, the second movable pin 824 will first move up under the extrusion guidance of the special-shaped guide rail 814, and then move down. When the second movable pin 824 moves up, it will be inserted into the rod 805. 23. The first movable pin 822 and the connecting guide rail 821 drive one side of the positioning ring 807 to tilt. At this time, the pen inside the placement slot 809 tilts, so that the pen slides down. If the pen tip 3 faces the connecting shaft 802, the pen is blocked by the bottom of the blocking pin 812 and cannot fall into the U-shaped receiving slot 803. At this time, the telescopic cylinder 804 continues to extend the shift rack 825 to contact the second transmission spur gear 827, so that the worm 817 moves along with the second transmission spur gear 827. 7 rotates synchronously, so that the worm 817 drives the turntable 808 to rotate 180 degrees through the worm wheel 819, and then the telescopic cylinder 804 shrinks. At this time, the second transmission spur gear 827 cannot drive the worm 817 to move under the action of the pawl 829 and the ratchet 826, so that the insertion rod 823 moves up and down during the shrinkage of the telescopic cylinder 804, so that one side of the turntable 808 can be tilted. At this time, since the pen shell 1 is facing the connecting shaft 802 , the pen shell 1 in the pen will move out of the placement slot 809 from under the blocking pin 812. When the pen tip 3 contacts the bottom of the blocking pin 812, the blocking pin 812 is guided by the inclined surface at one end of the pen tip 3 to move upward relative to the placement slot 809, so that the pen falls to the inner side of the U-shaped receiving trough 803. Then, the motor 801 drives the U-shaped receiving trough 803 to rotate clockwise to make the pen fall onto the conveyor 7. In this way, the orientation of the pen can be unified during the transportation process.

[0046] Please refer to Figure 7 、 Figure 8 、 Figure 9 The special-shaped guide rail 814 is divided into a first horizontal section 8141, a first inclined section 8142, a second inclined section 8143, and a second horizontal section 8144. The maximum distance from one end of the shift rack 825 to the second transmission spur gear 827 is equal to the maximum distance from the second inclined section 8143 to the first inclined section 8142.

[0047] In this embodiment, this structure is set up to make the insertion rod 823 remain stationary when the telescopic cylinder 804 continues to extend after the insertion rod 823 moves back and forth once. At the same time, when the telescopic cylinder 804 continues to extend, the shift rack 825 drives the second transmission spur gear 827 to rotate, thereby realizing the orderly movement of the insertion rod 823 and the rotation of the rotating column 806.

[0048] Please refer to Figure 1、 Figure 6 、 Figure 7 The distance from the bottom of the blocking pin 812 to the top of the guide roller 810 is less than the maximum diameter of one end of the pen tip 3.

[0049] In this embodiment, by setting this structure, the turntable 808 is tilted only when the pen housing 1 faces the U-shaped receiving trough 803, and the pens fall into the U-shaped receiving trough 803, thereby achieving the uniform orientation of the pens on the conveyor 7.

[0050] Please refer to Figure 1 、 Figure 7 The bottom of the blocking pin 812 is rotatably connected to a ball through a rotating shaft, and the end of the pen head 3 close to the first movable sleeve 2 has a conical inclined surface structure.

[0051] In this embodiment, this structure is provided to achieve unidirectional movement of the pen inside the placement slot 809, while also reducing the friction between the pen tip 3 and the bottom of the blocking pin 812 when moving out of the placement slot 809, further improving the smoothness of the pen when moving out of the placement slot 809.

[0052] Please refer to Figure 7 The center line of the positioning block 820 is coaxial with the center of the positioning ring 807 and the center of the turntable 808.

[0053] In this embodiment, this structure is provided to improve the stability of the swing of the turntable 808.

[0054] Please refer to Figure 8 Damping pads are provided at the connection points between the two ends of the worm 817 and the side connecting frame 815.

[0055] In this embodiment, by providing this structure, the second transmission spur gear 827 rotates relative to the worm 817 when the telescopic cylinder 804 contracts, while preventing the worm 817 from rotating along with the second transmission spur gear 827 during the contraction of the telescopic cylinder 804.

[0056] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
