The linear driving module can drive the flexible tube 2 to move forward, thereby driving the movement of the dispensing head 3. Since the dispensing environment is the inner wall of the special-shaped product 100, the dispensing head 3 may need to change directions and positions multiple times. Therefore, the flexible tube 2 is set as a pushing tool, and the flexible tube 2 can be bent to adapt to and pass through different inner cavity structures. The dispensing head 3 is used for dispensing glue on the inner cavity of the special-shaped product, and includes a glue inlet 31 and a glue outlet 32 located on different sides. One end of the flexible tube 2 is connected to the glue inlet 31. The glue inlet 31 is used to receive the glue output by the external glue conveying device, and then the glue flows out from the glue outlet 32. The glue outlet 32 is opposite to the inner wall of the special-shaped product 100. Specifically, it is opposite to the preset inner wall of the special-shaped product 100 where glue is to be dispensed. The glue conveying device is also connected to the glue inlet 31 and is used to convey glue to the dispensing head 3.

[0029] When the dispensing head 3 is located in the inner cavity of the special-shaped product 100, the glue outlet 32 is opposite to the inner wall of the special-shaped product 100. The driving servo platform 11 and the glue conveying device start the linear driving module to push the flexible tube 2. The flexible tube 2 drives the dispensing head 3 to move along the inner cavity of the special-shaped product 100. The glue flows from the glue conveying device into the glue inlet 31 and then flows to the inner wall of the special-shaped product 100 through the glue outlet 32, thereby realizing glue dispensing on the inner wall of the special-shaped product 100.

[0030] In one embodiment, the special-shaped product 100 is a double-lumen laryngeal mask, and tracheal wire is arranged inside. The tracheal wire needs to be pasted on the inner wall of the double-lumen laryngeal mask. There are grooves on the inner wall of the double-lumen laryngeal mask for accommodating the tracheal wire. To facilitate the automation and high efficiency of the dispensing work, the dispensing device for the inner cavity of the special-shaped product of the present application can be used. Align the dispensing head 3 with the inner wall opening of the double-lumen laryngeal mask, and the glue outlet 32 corresponds to the groove position of the double-lumen laryngeal mask. The driving servo platform 11 drives the dispensing head 3 to move along the inner wall of the double-lumen laryngeal mask, and at the same time applies glue to the grooves on the inner wall to facilitate the subsequent pasting and assembly of the tracheal wire. By using the dispensing device for the inner cavity of the special-shaped product, the automation of glue dispensing in the inner cavity of the special-shaped product is realized, the production efficiency is improved, and the dispensing effect is good.

[0031] In the present application, the dispensing head 3 is a profiling dispensing head. The shape of the dispensing head 3 is the same as the shape of the inner cavity of the special-shaped product 100. The movement trajectory of the dispensing head 3 is limited to prevent the dispensing head 3 from rotating inside the special-shaped product 100, so that the position of the glue outlet 32 remains constant, thereby realizing stable glue dispensing.

[0032] Please refer to Figure 4 , in the dispensing head 3 of the present application, it includes a main body 10 and a connecting portion 20. The main body 10 is a hollow shell, and the glue outlet 32 is provided on the main body 10. The connecting portion 20 protrudes from the outside of the main body 10. The connecting portion 20 includes a pipe body connecting portion 21 and a glue inlet pipe 22. Both the pipe body connecting portion 21 and the glue inlet pipe 22 are hollow cylinders. The glue inlet pipe 22, the pipe body connecting portion 21 and the main body 10 are connected in sequence and internally communicate in sequence. One end of the glue inlet pipe 22 away from the pipe body connecting portion 21 forms a glue inlet 31, and the glue inlet 31 is connected to a glue conveying device. The end of the flexible pipe 2 is sleeved on the pipe body connecting portion 21. When the flexible pipe 2 is pushed by the lead screw module, it can drive the dispensing head 3 to move together. Glue enters the dispensing head 3 from the glue inlet 31 and then overflows to the inner wall of the special-shaped product 100 through the glue outlet 32, thereby completing the dispensing.

[0033] The dispensing head 3 in the present application further includes a process hole 33. The setting of the process hole 33 facilitates the processing of the connecting portion 20 and the glue outlet 32 on the main body 10, and at the same time facilitates the cleaning of the inner cavity of the main body 10 of the dispensing head 3.
