Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a powder filling device. Background Art

[0002] Phosphor filling is a process used in the manufacture of fluorescent lamps. During this process, phosphor is evenly applied to the inner wall of the tube. When the gas inside the tube is excited by an electric current, it produces ultraviolet light. This ultraviolet light hits the phosphor, causing it to emit visible light, thus achieving the lighting effect.

[0003] However, traditional phosphor filling tubes are filled manually, and the manual operation process is time-consuming and slow, which cannot be compared with automated production lines, resulting in higher production costs. Due to the manual operation, product quality between different batches may vary greatly, making it difficult to ensure the consistency and reliability of each product. During the manual processing, phosphors are easily contaminated by the external environment, such as dust and moisture, which may affect the performance and life of the final product. During the manual operation, operators may directly contact phosphors, especially phosphors containing heavy metal components, as long-term contact is harmful to health. Manual operation makes it difficult to achieve high-precision phosphor distribution control, which may be a major obstacle for applications requiring precision coatings. In addition, to ensure a certain product quality, operators need to undergo special training, which increases human resource costs.

[0004] In view of this, the inventor specially designed a powder filling device, which resulted in the present invention. Utility Model Content
