[0034] Combination Figures 1 to 12The present embodiment provides an inflatable tube gluing device, comprising a base body 1 and a bottom mold 2, a positioning mechanism 3 and a gluing mechanism 4 arranged on the base body 1, wherein the bottom mold 2 is provided with a first limiting groove 21, the positioning mechanism 3 comprises a positioning block 31 located above the bottom mold 2 and provided with a second limiting groove 311, the positioning block 31 is driven by a positioning driving member 32 to abut against the bottom mold 2, and the corresponding second limiting groove 311 is aligned with the first limiting groove 21 to form a positioning channel for limiting the position of the inflatable tube 51; the gluing mechanism 4 is arranged toward the positioning channel side, and comprises a quantitative glue gun 41, a accommodating chamber 42, a flexible brush head 43 and a driving structure, the quantitative glue gun 41 is connected with the accommodating chamber 42 for quantitative glue supply, and the flexible brush head 43 is configured to be driven by the driving structure to extend into the accommodating chamber 42 for gluing, and to be pulled out of the accommodating chamber 42 after gluing, and flipped to a position facing the positioning channel, so as to extend into the inflatable tube 51 along the positioning channel for uniformly brushing glue.

[0035] For example, the bottom mold 2 is provided with a positioning groove 22 that is shaped like the airbag 5, and the first limiting groove 21 is connected to the positioning groove 22. The airbag 5 is placed on the bottom mold 2, the airbag body is limited by the positioning groove 22, and the inflation tube 51 is located in the first limiting groove 21. The gluing process is as follows:

[0036] 1. The positioning block 31 is driven by the positioning driving member 32 to move to abut against the bottom mold 2, so that the inflation tube 51 is clamped in the positioning channel to achieve the positioning of the inflation tube 51;

[0037] 2. The driving structure drives the flexible brush head 43 to extend into the accommodating chamber 42, and drives the quantitative glue gun 41 connected to the accommodating chamber 42 to supply glue quantitatively, so as to achieve quantitative gluing of the flexible brush head 43;

[0038] 3. After gluing, the driving structure drives the flexible brush head 43 to be pulled out from the accommodating cavity 42, and drives the flexible brush head 43 to flip to a position facing the positioning channel;

[0039] 4. The driving structure drives the flexible brush head 43 to enter along the positioning channel and extend into the inflation tube 51 to evenly apply glue.

[0040] After applying glue, the flexible brush head 43 is pulled out from the positioning channel and returns to the initial position under the drive structure, and the positioning block 31 returns to the initial position under the action of the positioning drive member 32, thereby preparing for the next application of glue.

[0041] It should be noted that, in this embodiment, a positioning channel is formed by the first limiting groove 21 on the bottom mold 2 and the second limiting groove 311 on the positioning block 31. The inflation tube 51 is limited by the positioning channel to avoid deviation and deformation of the inflation tube 51 during the gluing process, thereby ensuring uniform gluing and preventing glue overflow, thereby improving the quality and yield rate of the product. At the same time, the flexible brush head 43 made of flexible materials such as sponge can further prevent the deformation of the inflation tube 51 during the gluing process, and the quantitative glue gun 41 quantitatively supplies glue to the flexible brush head 43, which can also further prevent the problem of glue overflow.

[0042] In a preferred embodiment, an inlet for the quantitative glue gun 41 to enter is provided on the side of the accommodating chamber 42, and an outlet 421 for the flexible brush head 43 to enter and exit is provided on the top surface of the accommodating chamber 42. The inlet and outlet 421 of the accommodating chamber 42 are arranged on different surfaces, which can simultaneously drive the quantitative glue gun 41 to supply glue and the flexible brush head 43 to apply glue, thereby ensuring the stability of the glue amount. Preferably, a motor 431 is coaxially arranged on the flexible brush head 43 to drive it to rotate, and when the flexible brush head 43 is extended into the accommodating chamber 42 and into the inflation tube 51, the flexible brush head 43 is synchronously driven to rotate, so as to achieve uniform gluing and uniform brushing of the flexible brush head 43. The connection between the flexible brush head 43 and the motor 431 can be through a coupling or other connection structures, and is not limited to this and is not specifically limited.

[0043] On the basis of the above-mentioned embodiments, in an optional embodiment of the utility model, the positioning mechanism 3 includes a support frame, and support legs 33 for fixing to the base body 1 are arranged at both ends of the support frame, a cross beam 34 is arranged between the two support legs 33, a positioning drive member 32 is arranged on the cross beam 34, and a positioning block 31 is connected to the positioning drive member 32, and the positioning block 31 is driven by the positioning drive member 32 to move toward or away from the bottom mold 2.

Specifically, the flip assembly 45 includes a moving plate 451, a flip driving member 452, a rotating shaft 453 and a gear 454. The moving plate 451 is provided with a rack 4511. One end of the rotating shaft 453 is connected to the flexible brush head 43. The gear 454 is sleeved on the other end of the rotating shaft 453 and meshed with the rack 4511.

The moving assembly 44 includes a first driving member 441 and a second driving member 442. The first driving member 441 is fixed to the base 1 to drive the first moving block 443 to move in a direction close to or away from the positioning channel; the second driving member 442 is arranged on a fixed plate 444 vertically connected to the first moving block 443 to drive the second moving block 445 to move in a direction close to or away from the accommodating chamber 42. The flip driving member 452 is fixedly connected to the second moving block 445, and the moving plate 451 is movably arranged on the second moving block 445.

[0046] When applying glue:

[0047] 1. The second moving block 445 is driven to move by the second driving member 442 to move the bearing seat 455, so that the rotating shaft 453 connected to the flexible brush head 43 moves synchronously, thereby driving the flexible brush head 43 to extend into the accommodating cavity 42. At this time, the flexible brush head 43 is in a vertical state;

[0048] 2. Driving the motor 431 to drive the flexible brush head 43 to rotate, so as to achieve quantitative gluing of the flexible brush head 43 when the quantitative glue gun 41 supplies quantitative glue;

At this time, the bearing seat 455 connected to the second movable plate 451 is fixed, so that the gear 454 meshing with the rack 4511 drives the rotating shaft 453 to rotate, driving the flexible brush head 43 to flip to a position facing the positioning channel (i.e., a horizontal state);

[0051] 5. The first driving member 441 drives the first movable plate 451 to move toward the positioning channel, thereby driving the flexible brush head 43 to enter along the positioning channel and extend into the inflation tube 51. The flexible brush head 43 rotates at a constant speed under the action of the motor 431, thereby achieving quantitative and uniform glue brushing, preventing glue from overflowing, and ensuring product quality.
