Die used for sticking film for nixie tube

Abstract

The invention discloses a die used for sticking a film for a nixie tube, comprising a square die plate, wherein a plurality of lugs matched with a nixie tube are uniformly distributed on the upper surface of the die plate, a clearance is formed between two lugs, a positioning groove and a positioning lug matched with the shape of the positioning groove are respectively arranged on two symmetricalside faces of the die plate, the positioning lug is set in a dovetail shape, the lugs are detachably connected with the die plate, positioning pillars are arranged at the bottoms of the lugs, and positioning holes matched with the positioning pillars are formed in the die plate. The die used for sticking a film for a nixie tube, disclosed by the invention, has the advantages of being steady in connection structure and high in film sticking efficiency and ensuring the film sticking quality.

Description

technical field [0001] The invention relates to an auxiliary device for sticking film of a digital tube, in particular to a mold for sticking a film of a digital tube. Background technique [0002] LED digital tubes (LED Segment Displays) are packaged together by multiple light-emitting diodes to form an "8"-shaped device. The leads have been connected internally, and it is only necessary to lead out their individual strokes and common electrodes. The digital tube is actually composed of seven light-emitting tubes in a figure-eight shape, and adding a decimal point is eight. These segments are represented by the letters a, b, c, d, e, f, g, dp, respectively. [0003] In the production process of digital tubes, the steps generally include: putting the pins on the circuit board, fixing the chip on the circuit board, baking, initial inspection, glue filling and general inspection. After the above steps are completed, the surface of the nixie tube will be pasted with a film. T...

Problems solved by technology

After completing the above steps, the surface of the digital tube will be pasted with a film. The traditional method of pasting the film is done individually. The disadvantage of doing it alone is that it is not only inefficient, but also difficult to operate, and dust and impurities are easy to enter

[0004] In the prior art, for example, Chinese patent (CN201420650320.7) discloses a nixie tube film sticking equipment and production equipment, which can arrange multiple nixie tube molds in sequence on a base plate, and apply films to multiple nixie tubes at one time. That is to say, the efficiency of film application is improved, and the entry of dirt such as dust and impurities is avoided during the process of film application, which improves the quality of digital tube film application. Multiple base plates can be arranged for film lamination, but since there is no connection structure between adjacent base plates, it is easy for adjacent base plates to move relative to each other during film lamination, which affects the quality and efficiency of film lamination, and although the nixie tube mold of this equipment can It is installed on the bottom plate in a detachable way, but it is connected magnetically. After a long time of use, the magnetism will weaken, which will cause the connection between the digital tube mold and the bottom plate to be unstable and easy to move.
