Description

Technical Field

[0001] The utility model relates to the technical field of packaging and assembly, in particular to a thread precision alignment mechanism. Background Art

[0002] In the current thermos industry, the design of the logo and handle / drinking port of the thermos packaging cup considers that the logo and accessories need to have a fixed positional relationship to ensure that the accessories and the cup body maintain the vertical and angular deviation tolerance. During the manufacturing and assembly process, the thermos cup and the cup lid are marked after being adapted, and then the logo is printed and the handle accessories are assembled. There are repeated processes, which wastes a lot of manpower. The industry urgently needs to solve the bottleneck process of alignment and solid line marking. To this end, in response to the above problems, a thread precision alignment mechanism is designed to better meet the actual use needs. Utility Model Content

[0005] Preferably, a boss is fixed on the bottom plate, and an arc-shaped groove cooperating with the thermos cup is provided on the boss, so that the thermos cup can be lifted by the boss.

[0006] Preferably, the thermos cup and the ferrule are nested and a slot is provided on the side of the ferrule facing the fixed plate. The nesting of the thermos cup and the ferrule facilitates the assembly and disassembly of the ferrule.

[0007] Preferably, the fixing plate is fixed with a convex strip, and the convex strip is snap-fitted to the slot on the sleeve. The snap-fitting and limiting effect between the convex strip and the sleeve can provide basic protection for the rotation of the thermos cup.

[0009] Preferably, a positioning piece is nested and fixed on the double-head pressure plate, and the positioning piece contacts the thermos cup to achieve a limiting effect, and the positioning piece is elastic. Through the elastic effect of the positioning piece, the positioning piece can be easily adapted to the thermos cup, ensuring the stability of the thermos cup's compression.

[0010] Compared with the existing technology, the beneficial effects of the utility model are: the thread precision alignment mechanism adopts a clamping and rotating mechanism, which can thread-match the thermos cup and the cup cover, thereby ensuring the precise docking of the thermos cup and the cup cover, completely abolishing the manual marking and alignment production process in the industry, and in conjunction with the clamping and positioning mechanism, it can facilitate the fixation of the thermos cup and the welding of the handle, greatly improving the convenience of production.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0016] See also Figure 1-Figure 3 The utility model provides a technical solution: a thread precision alignment mechanism, including a base plate 1, a push cylinder 2 is fixed on the upper end surface of the base plate 1, a fixing bracket 3 is installed on the output end of the push cylinder 2, a rotating motor 4 is fixed on the fixing bracket 3, a three-claw cylinder 5 is fixed on the output end of the rotating motor 4, the three-claw cylinder 5 and the thermos cup 6 are clamped and fixed, a fixing plate 8 is also fixed on the right side of the upper end surface of the base plate 1, and a positioning cylinder 9 is also fixed on the base plate 1.

[0017] A boss 101 is also fixed to the bottom plate 1, and an arc-shaped groove is provided on the boss 101 to cooperate with the thermos cup 6; the thermos cup 6 and the ferrule 7 are nested and connected, and a slot is provided on the side of the ferrule 7 facing the fixed plate 8; a convex strip 801 is fixed to the fixed plate 8, and the convex strip 801 is snap-fitted to the slot on the ferrule 7; a downward-pressing cylinder 10 is also fixed to the output end of the positioning cylinder 9, and a double-headed pressing plate 11 is fixed to the output end of the downward-pressing cylinder 10; a positioning piece 1101 is nested and fixed on the double-headed pressing plate 11, and the positioning piece 1101 contacts the thermos cup 6 to achieve a limiting effect, and the positioning piece 1101 is elastic;

[0018] When using the thread precision alignment mechanism, Figure 1-Figure 3 As shown, first, the thermos cup 6 and the ferrule 7 are nested to achieve the installation of the ferrule 7, and then the thermos cup 6 is matched with the three-claw cylinder 5, and the three-claw cylinder 5 is started to realize the clamping effect of the lid of the thermos cup 6, and at this time the thermos cup 6 is in contact with the boss 101, and then the push cylinder 2 is controlled to drive the three-claw cylinder 5 to move horizontally, thereby driving the thermos cup 6 to move, until the ferrule 7 on the thermos cup 6 is engaged with the convex strip 801 to achieve positioning. After the positioning is completed, the three-claw cylinder 5 is driven to rotate 30° forward and reverse by starting the rotating motor 4. Since there is a large friction between the cup body of the thermos cup 6 and the ferrule 7 at this time, the cup body of the thermos cup 6 does not move, that is, the three-claw cylinder 5 drives the cup lid of the thermos cup 6 to rotate 30° forward and reverse to ensure the The cup body of the thermos cup 6 is precisely matched with the cup cover thread. Finally, by starting the positioning cylinder 9, the position of the downward pressure cylinder 10 and the double-headed pressure plate 11 can be driven to adjust the position of the positioning member 1101 to ensure that the positioning member 1101 is accurately matched with the thermos cup 6. Then the downward pressure cylinder 10 is started to drive the double-headed pressure plate 11 and the positioning member 1101 to move downward. When the positioning member 1101 contacts the thermos cup 6, the positioning member 1101 itself is elastic. The perfect match between the positioning member 1101 and the thermos cup 6 is achieved, thereby realizing the compression and limiting of the thermos cup 6. Subsequently, the handle is matched with the double-headed pressure plate 11 to achieve positioning. Finally, the handle can be welded by the welding mechanism. This is the working principle of the thread precision alignment mechanism.
