What I introduced here is synchronous laser welding equipment, which uses a high-power semiconductor laser as its welding light source, which has the advantages of fast welding time, low thermal effect, and low welding thermal stress, effectively improving production and welding quality.
- Use semiconductor laser units with high power;
- including several sets of synchrotron radiation light sources;
- power and light emission of each welding area can be adjusted according to the needs to save installation space;
- Integrated water cooling structure: Equipment has the function of automatic changing, and locking, and identifies the serial number and version of nesting automatically.
- Support 1,4-meter through-type taillights and fixed-side taillights for one set of laser welding tool with two cavities.
Plastic synchrotron laser transmission welding presses the plastic parts of the upper layer through a near-infrared band and the plastic parts of the lower absorption layer together, through the laser beam energy melting of the lower side material, under the action of pressure and quickly solidified with the upper material; Plastic synchronous laser welding has the advantages of fast welding speed, small thermal stress, small welding deformation, no vibration, dust and high temperature in the welding process, suitable for automobile,3C electronics and medical industries.
in the design, the outgoing beam is homogenized, and the spot has an obvious flat-top distribution and good uniformity, which is suitable for laser welding plastics.
Used to support the welding are used for optical structure design of optical fiber orientation and the wedge of light guide plate structure, which is strictly by our size the positioning of the optical fiber welding efficiency and the uniformity of the energies of the beams test results perform the design, structure design of guide plate to a great extent improve the efficiency of welding, using the characteristics of synchronous welding way is as follows:
1. The design of the uniform distribution of each fiber combined with the light guide plate gives the flexibility of 3D welding. The fiber can be freely distributed according to the copy surface of the product to be welded, and the welding stability can guaranteed.
2. The design of the light guide plate greatly improves the welding efficiency. Under the condition of ensuring good transmittance, the welding duration is generally about 3-6 seconds;
3. The energy concentrated on the welding line can instantaneously melt the underside materials, which can greatly reduce the thermal deformation and internal stress of the welded products when compared with traditional welding;
4. Each light source is separately controlled, and the power and light time can be separately controlled according to debugging requirements.
