Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic welding, and in particular to welding equipment for PP material one-piece formed flat lamps. Background Art

[0002] The existing ultrasonic welding equipment has a large die, and the sound waves are dispersed, so the energy acting on the product welding position is small, which can easily cause uneven welding or desoldering, a high scrap rate for production defects, and it is difficult to debug the die level on the equipment. The debugging cycle is long, the production process is uncontrollable, and high requirements are placed on the professional and technical level of the personnel. In addition, under the existing equipment conditions, in order to meet the welding effect, increasing the welding time and equipment power can easily cause the die on the equipment to be scrapped, the cost of equipment spare parts is high, and production costs are increased.
