[0002] A digital tube, also known as a glow tube, is an electronic device that can display numbers and other information. The glass tube includes an anode made of a metal wire mesh and multiple cathodes. The shape of most cathodes of the digital tube is a number. The tube is filled with a low-pressure gas, usually mostly neon plus some mercury and / or argon. When a certain cathode is charged, the digital tube will emit colored light, depending on the gas in the tube, usually orange or green.

[0077] An automatic film pasting device for digital tubes, its working principle: A whole roll of film is set on one side of the film pressing mechanism 1. The end of the whole roll of film enters between the rubber roller body 16 and the film pressing workbench 11. Under the action of the rubber roller body 16, the pre-tightening of the film and the base film is realized. By adjusting the first lifting mechanism 14 and the second lifting mechanism 15, the height of the rubber roller body 16 and the gap between the rubber roller body 16 and the film pressing workbench 11 can be controlled, and then the acting force between the rubber roller body 16 and the film pressing workbench 11 can be controlled. After the film pressing is completed, the film proceeds to the next process such as the film pressing workbench 11. The film pasted on the base film advances from the film pressing workbench 11 towards the film tearing workbench 22. When it reaches the workbench gap, the film and the base film are separated. The film is picked up by the manipulator and pasted onto the digital tube. The used base film passes under the workbench gap, and then passes above the film tearing tension roller 232 and between the film tearing driving roller 242 and the film tearing lifting roller 253 in sequence. By adjusting the third lifting mechanism 251 and the fourth lifting mechanism 252, the film tearing driving roller 242 and the film tearing lifting roller 253 generate frictional force on the base film. The film tearing driving roller 242 rotates under the drive of the film tearing motor 241, and then drives the base film to advance and enter the base film passing groove 255 for the recycling of the base film.

[0078] Two disk bodies with digital tubes are respectively placed on the first product seat 382 and the second product seat 394. The initial position of the first product seat 382 is position A, and the initial position of the second product seat 394 is position B. The robotic arm 5 picks up the film on the base film and then pastes the film onto the digital tubes on the first product seat 382 in sequence according to the arrangement order of the digital tubes. When all the digital tubes on the first product seat 382 are pasted, the second sliding table assembly 39 works. The second sliding table lifting cylinder 393 controls the second sliding sleeve lifting plate to descend, and then the second rodless cylinder 37 controls the second sliding table plate 391 to move forward. The first rodless cylinder 36 controls the first product seat 382 to move from position A to position B. After the first sliding table plate 381 moves to position B, the second sliding table lifting cylinder 393 controls the second product seat 394 to rise towards position A, and then the robotic arm 5 continues to paste the film onto the digital tubes on the second product seat 394. Such cyclic operation is carried out until the film pasting is completed.

[0079] Take out the digital tube with the diaphragm pasted from the loading and unloading slide table mechanism 3, and put it into the diaphragm pressing mechanism 4 through the feeding chute. After placing, control the pressing lifting cylinder 43 to work, lift the pressing lifting plate 44, and the disc support assembly 45 on the pressing lifting plate 44 lifts the disc, so that the disc is separated from the two pressing feeding plates 424, and the digital tube is in contact with the rubber pad 425 at the top for pressing. After pressing, the pressing lifting cylinder 43 retracts, and the disc returns to the feeding chute formed by the pressing feeding plates 424. Take out the disc, and the film pasting work of the entire digital tube is completed.

[0080] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
