DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] like Figure 1-7As shown, a penholder tail plug insertion device 100 in one embodiment of the utility model comprises a main frame 10, an assembly mechanism 20 and a feeding mechanism 30. The feeding mechanism 30 is arranged on one side of the assembly mechanism 20, and is used to store the tail plug and transport the tail plug to the assembly mechanism 20. The assembly mechanism 20 is fixed on the main frame 10 and is used to insert the tail plug into the penholder to complete the assembly.

[0028] Specifically, the assembly mechanism 20 includes a driving assembly, a guide sleeve 22 and a push rod 23. The guide sleeve 22 is supported on the main frame 10, and one end of the guide sleeve 22 is an assembly portion 221. Figure 2 As shown, a plurality of axially extending flexible positioning claws 24 are fixed on the assembly portion 221, and each positioning claw 24 is provided with a guide portion 241 convex radially inwardly along the guide sleeve 22. The push rod 23 is inserted into the guide sleeve 22, and the driving assembly is connected to and drives the push rod 23 to move in the guide sleeve 22. The feeding mechanism 30 includes a barrel 31 for storing the tail plug, and a conveying pipe 32 connected to the barrel 31 and used to transfer the tail plug to the guide sleeve 22.

[0029] The tail plug is moved from the barrel 31 to the guide sleeve 22 through the feed pipe 32, and the driving assembly drives the push rod 23 to push the tail plug to the assembly part 221, and fix the pen body to the assembly part 221. Since a plurality of radially inwardly convex positioning claws 24 are fixed on the assembly part 221, the pen body presses the positioning claws 24 outward when inserted into the assembly part, and the positioning claws 24 produce a certain deformation to position and fix the pen body. The tail plug is also positioned twice when passing through the assembly part 221 and the positioning claws 24, so the tail plug can be inserted into the pen body in the correct posture to improve the assembly success rate and production efficiency.

[0030] Specifically, the guide part 241 forms a vertical retaining wall 2411 on the fixed side of the pen barrel, and the pen barrel is blocked by the retaining wall 2411 after being inserted. The retaining wall 2411 is used to determine the fixed position of the pen barrel to prevent the pen barrel from being inserted too deeply. At the same time, the guide part 241 forms an inclined guide wall 2412 on the side of the tail plug, and the guide wall 2412 extends from the side of the assembly part 221 to the side of the retaining wall 2411. The guide walls 2412 of all the positioning claws 24 form a funnel-shaped area. When the tail plug passes through this area, it is partially inserted into the pen barrel, and then it contacts and squeezes the guide wall 2412 when continuing to insert to open the positioning claw 24. In this process, the push rod 23 and the guide part 241 can continuously maintain the posture of the tail plug, ensuring that the tail plug is inserted into the pen barrel in the correct posture.

[0031] Preferably, a plurality of positioning claws 24 are equidistantly arranged on the assembly portion 221 along the circumference of the guide sleeve 22, so as to provide uniform fixing and positioning positions for the pen holder and the tail plug from all directions, and prevent the tail plug from deviating. Furthermore, a rubber ring (not shown) is wrapped around the assembly portion 221, and the rubber ring places all the positioning claws 24 on the assembly portion 221 to prevent the positioning claws 24 from being disengaged, and assists in resetting the positioning claws 24 after completing a single insertion operation.

[0032] The assembly part 221 is provided with a plurality of first slots 223 for holding the positioning claws 24 in an array, and the number of the first slots 223 is the same as the positioning claws 24, and is used to prevent the positioning claws 24 from shifting. At the same time, the assembly part 221 is also provided with an annular second slot 224, which is used to limit the rubber ring and prevent the rubber ring from shifting. Correspondingly, a fourth slot 243 is formed on the positioning claw 24, which has the same width as the second slot 224, and is used to hold the rubber ring.

[0033] It is conceivable that a plurality of fourth slots 243 may be provided on the positioning claw 24 for winding a plurality of rubber rings to further improve the limiting and fixing effects.

[0034] To further improve the fixing effect of the positioning claw 24 on the assembly part 221, a protrusion 242 is provided at the end of the positioning claw 24, and a corresponding annular third groove 225 is opened on the assembly part 221. The protrusion 242 is limited in the third groove 225 to prevent the positioning claw 224 from axial movement.

[0035] In order to further ensure the positioning effect of the tail plug in the assembly part and prevent it from deviation, the diameter of the assembly part 221 towards the tail plug side gradually decreases along the insertion direction of the tail plug, forming a funnel shape. After entering the assembly part 221, the tail plug is pre-positioned at this position, and then passed through the positioning claw 24 and inserted into the pen body.

[0036] It is easy to imagine that a groove 231 is provided at the end of the push rod 23 that contacts the tail plug. The groove 231 can accommodate the tail of the tail plug, and thus can also have a partial positioning effect on the tail plug.

[0037] like Figure 1 and 6 As shown, the main frame 10 includes a mounting plate 11, a guide groove 111 is provided on the mounting plate 11, and a guide sleeve 22 is movably arranged in the guide groove 111 and is driven to move by a second cylinder 12. In this embodiment, the second cylinder 12 is fixed to the main frame 10, and the movement direction of its output shaft is the same as the extension direction of the guide groove 111. The second cylinder 12 is connected through a push plate 13 and drives the guide sleeve 22 to move.

[0038] In one embodiment, the guide sleeve 22 is provided with a feed port 222 on the side wall, and the tail plug enters the guide sleeve 22 through the feed port 222. Preferably, a dislocation plate 33 and a first cylinder 34 connected and driving the dislocation plate 33 to move are also provided at the outlet of the feed pipe 32. The dislocation plate 33 is supported above the mounting plate 11, and a bayonet 331 for accommodating the tail plug is provided thereon. The first cylinder 34 drives the dislocation plate 33 to move back and forth between the outlet of the feed pipe 32 and the feed port 222. In the actual working process, the first cylinder 34 drives the dislocation plate 33 to move toward one side of the feed pipe 32, so that the bayonet 331 is aligned with the outlet of the feed pipe 32, and the tail plug falls into the bayonet 331 and is supported on the mounting plate 11. Then, the first cylinder 34 drives the dislocation plate 33 to move toward one side of the feed port 222, and the buckle 331 is aligned with the feed port 222, and the tail plug falls into the guide sleeve 22.

[0039] In order to match the above-mentioned setting, a convex strip 112 is provided on the surface of the mounting plate 11, and the dislocation plate 33 is supported on the convex strip 112 to reduce the contact area with the mounting plate 11 and reduce friction. At the same time, the convex strip 112 is also used to support the tail plug. In addition, in order to prevent the guide sleeve 22 from interfering with the dislocation plate 33, part of the side wall of the guide sleeve 22 is cut off, and the entire side wall cut is flush with the surface of the mounting plate 11. The part of the side wall of the guide sleeve 22 that is cut off is the feed port 222. Since the guide sleeve 22 needs to move in the guide groove 111, and one end also needs to be entered by the push rod 23, for the convenience of setting, the side wall of the guide sleeve 22 from the assembly part 221 to the other end is cut off as a whole to form a larger feed port 222. Therefore, the guide sleeve 22 will not interfere with the dislocation plate 33 when moving, and both can move freely.

[0040] like Figure 1 As shown, the driving assembly includes a track 211, a slider 212, a connecting plate 213, an eccentric wheel 214 and a pulley 215. The track 211 is parallel to the guide sleeve 22. The slider 212 is supported on the track 211 and can move along the track 211. The connecting plate 213 is fixed to the slider 212 and is provided with a slide groove 2131. One end of the pulley 215 is fixed to one end of the eccentric wheel 214, and the other end is limited in the slide groove 2131. The other end of the eccentric wheel 214 is used to connect to the driving motor (not shown), and the push rod 23 is fixed to the slider 212. When the driving motor drives the eccentric wheel 214 to rotate, the pulley 215 rotates around the rotation center of the eccentric wheel 214. Since it is limited in the slide groove 2131, it moves in the slide groove 2131 and drives the connecting plate 213 and the slider 212 to move along the track 211, thereby driving the push rod 23 to move in the guide sleeve 22.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0042] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
