Efficient UV curing equipment suitable for the production of miniature speakers－UV CONVEYOR 40

Micro speakers generally include sound film, voice coil, basin stand, magnetic pole, magnetic core, magnetic cylinder, etc. All these small parts are assembled with glue. A small micro-speaker sometimes uses glue as much as 8 places.

UV glue has been used in the high-end market for a long time since it is regarded as the most important bonding of micro-speakers-the bonding of sound film and voice coil. Due to the fast curing speed, high production efficiency, good product consistency, high bond strength and environmental friendliness of UV glue, it is gradually being used by more and more speaker manufacturers, especially those who want to enhance the strength of the enterprise and improve the quality of the product Optimistic about the manufacturers.

After choosing the UV glue, how to choose the appropriate UV light curing equipment for production is very important. Common problems at present, including high temperature of curing cabinet, long curing time, large volume, large power consumption, etc., cannot reflect the superiority of light curing, an efficient and environmentally friendly process. The following is a brief introduction to the considerations for the selection of conveyor belt UV systems:

UV light curing intensity should be sufficient: mass production requires high production efficiency. Higher UV light curing intensity and faster conveyor belt will greatly increase the capacity of a single device. UVITRON UV CONVEYOR 40 adopts a dual-lamp structure, many applications can meet the application with a single lamp, and there is a lot of room for productivity improvement. Many people will consider whether the 400W bulb is enough? UV CONVEYOR 40 with two sets of light sources, the energy density can reach 16J / cm2, compared with the curing needs of general UV glue 2J / cm2 to 3J / cm2, it can meet the requirements of energy consumption and speed.

Low temperature inside the curing cabinet: To increase the light intensity, it is necessary to increase the lamp power. Most UV conveyor belts use UV lamps ranging from 3KW to 10KW to produce relatively high UVA intensity. However, the production of micro-speakers also has strict temperature requirements. The power consumption of 3KW-10KW is converted into heat, which causes the temperature of the cabinet to rise rapidly, generally within 80-120 degrees, and many plastic parts can no longer bear. UVITRON's high-efficiency lamp and power design, 400W bulb, can produce 100mw / cm2 of UVA light intensity (under the parabolic reflector), and at the same time with the built-in thermal insulation filter, effectively control the problem inside the box Can be controlled below 60. If connected to the factory cooling air system, the temperature can be reduced a lot. You do not need to worry about component damage.

The conveyor belt is small in size and has little impact on other equipment: high-performance components are generally small in volume, but the production workshop environment is very high, such as temperature, humidity and cleanliness. UV CONVEYOR 40 The light source part and the power supply are all integrated together, and the conveyor belt does not have too many unnecessary devices. The entire device appears compact and simple. The volume is small and compact, and the required power is very low, which will basically not affect other devices. The usual UV conveyor belt requires a large distribution cabinet power supply and conveyor belt system. It needs to be adjusted to the factory hardware environment before it can be used. It also has a greater impact on noise and cleanliness. The UV CONVEYOR 40 with two sets of light sources weighs only 35KG, and the volume is very compact. Would you still choose those conveyor belt equipment over 100KG?

Ozone generation and safety protection: The main safety hazards of the conveyor belt UV curing machine are ozone generation and UV protection. Some high-power UV conveyor belts may also need to consider the safety of the power box. Ultraviolet light, especially short-wavelength ultraviolet light, such as 250nm, will excite oxygen to produce ozone. Lamps with higher power generally produce higher ozone. It is usually equipped with an exhaust port to connect to the factory exhaust system. UV CONVEYOR 40 has a 3-inch exhaust port. Another UV light protection problem, the UV CONVEYOR 40 light source part adopts a fully enclosed design, and the UV protection door curtain is arranged at the input and output ports, which is very safe for the operator.
