Description
Technical Field
The utility model relates to the field of manufacturing of photomultiplier tubes, in particular to a tool for coating a conductive coating in a tube shell coating process.
Background
Vacuum evaporation coating is one of the most common methods for making thin films. In vacuum evaporation coating, a metal film is evaporated on the inner wall of a glass tube shell in a main form. Many of the glass envelopes require a conductive coating on the inside wall. In the field of industrial coating, conductive coating is the most important method for connecting a metal film and different metal electrodes. The conductive coating is generally coated on the inner wall of the glass tube shell, and can play a role in improving conductivity and protecting the metal film from being scratched by the metal electrode. When the conductive coating is coated, the conductive coating is coated on the inner wall of the glass tube shell according to the required shape and position accurately. Workers are required to manually apply the conductive coating and then clean the glass tube shell. In the process of coating the conductive coating, the phenomena of inaccurate coating position and irregular coating shape often occur. The method wastes time and materials and is easy to pollute the tube shell. Therefore, a tool for coating the conductive coating is needed, and the conductive coating can be coated quickly, efficiently and accurately.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1, a tool for applying a conductive coating includes: the glass tube shell positioning device comprises a stainless steel base 1, a universal joint 2, a glass tube shell positioning clamp 3, a conductive coating positioning tool 4 and a glass tube shell 5.
As shown in fig. 2, a stainless steel base 1 is used to stabilize the novel conductive coating application tool. One end of the universal joint 2 is fixed on the stainless steel base, and the other end is fixed on the glass tube shell positioning clamp 3. The direction and the position of the glass tube shell positioning fixture 3 can be adjusted at will according to different requirements of operators, so that the coating operation of the conductive coating is facilitated. The glass tube shell positioning fixture 3 is mainly used for bearing the glass tube shell 5 and fixing the conductive coating positioning tool 4. The conductive coating positioning tool 4 is typically made of a thin metal sheet in order to prevent the conductive coating positioning tool 4 from changing its position during use, which could affect the application of the final conductive coating. Two thin grooves are arranged on the glass tube shell positioning fixture 3 and used for fixing the conductive coating positioning tool 4. The glass envelope is placed on the conductive coating positioning means 4. The corresponding position of the conductive coating positioning tool 4 is provided with a pattern shape to be coated, after the glass tube shell 5 is placed, the sight line penetrates through the glass tube shell to coat the conductive coating according to the pattern shape on the conductive coating positioning tool 4 because the glass tube shell 5 is transparent.
As shown in fig. 3, the size and position of the glass tube positioning jig 3 and the conductive coating positioning tool 4 are changed according to the position and shape of the glass tube and the conductive coating.
Finally, it is noted that the disclosed embodiments are intended to aid in further understanding of the utility model, but will be understood by those skilled in the art; various substitutions and modifications are possible without departing from the spirit and scope of the utility model and the appended claims. Therefore, the present invention should not be limited to the disclosure of the embodiment.
