Description

Technical Field

[0001] This utility model belongs to the field of T-iron surface treatment technology, and more specifically, it relates to a T-iron pickling device for loudspeakers. Background Technology

[0002] In loudspeaker manufacturing, the T-iron is a key magnetic component, and its surface cleanliness directly affects its electroacoustic performance. Traditional acid pickling processes have the following technical drawbacks:

[0003] I. Significant Safety and Health Hazards: Existing pickling equipment is mostly open-type tanks, with a dispersion rate of over 30% for hydrofluoric acid mist (HF) released during the pickling process. Long-term exposure to corrosive gases can easily cause respiratory damage to operators. Manual handling of heavy-duty iron involves direct contact with the acid solution, posing a significant risk of workplace injury.

[0004] Second, low process efficiency: Traditional equipment relies on manual operation of individual components, and the process of handling, pickling, and draining is time-consuming. Furthermore, large fluctuations in acid concentration lead to uneven pickling and low batch pass rates. The bulky rack structure and frequent jamming during lifting further slow down the production line.

[0005] 3. Short equipment lifespan and frequent maintenance: Acid mist corrosion causes moving parts to rust and fail, resulting in long monthly downtime for maintenance.

[0006] Therefore, this utility model provides a T-iron pickling device for loudspeakers. Utility Model Content

[0007] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a T-iron acid washing device for horns, which realizes fully automatic T-iron handling through the combination of three-axis drive and electromagnetic adsorption, avoids pollution leakage through double-layer sealing structure and acid mist treatment system, and ensures long-term stable operation through titanium alloy bracket, achieving three core advantages: safety, environmental protection and durability.
