5. The automatic device for coating the inner surface of a metal tube according to claim 4, characterized in that: A T-shaped transmission member is connected to the push block of the lower push cylinder, and the two ends of the T-shaped transmission member are respectively connected to two cross beams, and the front and rear ends of the two cross beams are connected to the upper support plate through guide columns, and the lower bending forming plate is installed on the upper support plate; The upper support plate is provided with a strip-shaped notch for the push rod to slide left and right; The lower support plate is provided with a guide hole to which the guide column is slidably connected.

6. The automatic device for coating the inner surface of a metal tube according to claim 1, characterized in that: The first glue spraying assembly includes a first support seat and a first linear slide mechanism installed on the first support seat and used for left and right linear motion. The first glue spraying nozzle is detachably connected to the slide of the first linear slide mechanism.

7. The automatic device for coating the inner surface of a metal tube according to claim 6, characterized in that: The second glue spraying assembly includes a second support seat and a second linear slide mechanism installed on the second support seat and used for left-right linear motion, a second support frame is detachably installed on the slide of the second linear slide mechanism, a second guide rod is installed on the second support frame, and an end of the second guide rod is detachably connected to the second glue spraying nozzle; A second sliding support frame is installed on the second support seat, and the second sliding support frame is slidably connected to the second guide rod.

8. The automatic device for coating the inner surface of a metal tube according to claim 1, characterized in that: The diaphragm comprises metal meshes arranged inside and outside and an insulating outer layer, the insulating outer layer is provided with the holes, and the insulating outer layer covers all meshes of the metal meshes.

9. The automatic device for coating the inner surface of a metal tube according to claim 1, characterized in that: The conveyor belt is provided with a mounting block, and the mounting block is used for detachably connecting with a metal pipe fixing seat, and the metal pipe fixing seat is provided with a bracket for longitudinally inserting the metal pipe.

10. The processing method of the automated device for coating the inner surface of a metal tube according to claim 1, characterized in that: The steps include: Step 1: The metal tube feeding mechanism feeds the metal tube onto the conveyor belt; Step 2: The glue spraying process and the film cutting process are carried out simultaneously; During the glue spraying process, the conveyor belt transfers the metal tube to between the first glue spraying assembly and the second glue spraying assembly. After the front and rear sliding mechanisms slide into place, the lifting cylinder is pressed down, the upper limit member presses down the metal tube, and the limit clamping claw clamps the metal tube bracket in the front and rear directions. The slide of the first linear slide mechanism moves to the right. After moving into place, the positioning clamping claw expands outward, and the glue spraying nozzle of the second glue spraying assembly extends into the metal tube for glue spraying, and the glue spraying nozzle of the second glue spraying assembly withdraws from the metal tube; the first glue spraying nozzle sprays glue, and after glue spraying, the first glue spraying nozzle withdraws from the metal tube; During the film cutting process, the film cutting component cuts the film; the film transfer component transfers the cut film to the bending and pushing component to bend the film; when the film transfer component transfers the film from the film cutting component to the bending and pushing component, the blowing mechanism blows the film chips; Step 3, the bending and pushing component pushes the bent membrane into the metal tube on the conveyor belt; Step 4: The plugging piece installation mechanism pushes the plugging piece into the end of the metal pipe.
