Model: DH-JZ200W

Jewelry laser welding machine is a laser welding machine developed and designed for jewelry, pendants and ornaments. The special plane is dedicated, with strong pertinence and application, and is mainly used for welding and repairing materials such as gold, silver, copper, nickel, chromium and stainless steel. Laser welding is widely used in modern industrial production and manufacturing. Through the action of laser on the surface of materials, instantaneous high temperature generates heat, which makes the surface of materials melt and penetrate into the interior, and solidifies to form a molten pool. Laser welding has the advantages of reliable performance, beautiful appearance, safety, environmental protection and high efficiency, which can realize fine welding and precise welding and play an important role in improving jewelry technology.

The laser welding machine for jewelry includes an outer casing, a laser power supply, a cooling system, a software control system, an optical system, an optical structure, a microscope, a CCD imaging system, and an electrical control system.

This paper mainly introduces the manufacturing process of jewelry laser welding machine and the advantages of DH LASER jewelry laser welding machine, so that our customers and friends can better, more broadly and comprehensively understand and choose the appropriate jewelry laser welding machine and jewelry laser welding machine manufacturer.

1. According to the characteristics of jewelry welding process, combined with the needs of customers and market conditions, the laser welding machine for jewelry should be compact in appearance, not too large in volume, with good heat dissipation and strong durability. Microscope or CCD imaging system with magnifying observation has the characteristics of high optical conversion efficiency, high laser energy density and high peak energy. The color conforms to the customs and habits of some countries, the operation is convenient and comfortable, and it conforms to ergonomics.
2. 
   
3. It is not tired when operating the machine for a long time, and it is harmless to the operator and the environment, and there is no pollution such as waste gas, waste residue, waste water and noise.

1. The casing is generally made of 304 stainless steel with a thickness of 1.5mm, which is formed by laser cutting, numerical control bending, laser welding, polishing and industrial cleaning. Choose environmental protection paint, automatic line spraying, high-temperature sealed baking, etc. The whole casing is durable, stain-resistant and corrosion-resistant, and different colors can be customized according to customers' needs. The optical lens is made of Shi Ying, which has a good thermal effect. The transmittance of optical coating is 99.99%, the radius of curvature of the mirror is R=3M, and the lens error accuracy is 0.001mm.

3. The laser power supply adopts 18000UF capacitor imported from Japan, German high-frequency IGBT and controllable inverter circuit design, which has the functions of temperature, water pressure and undervoltage alarm, and improves the photoelectric conversion benefit to 6%. The software design has the functions of current, pulse width, frequency, optical beam diameter, language, parameter setting and password.

According to the design requirements of drawings, strictly control the quality and check the quality level by level. The appearance of incoming materials is free from trachoma, scratch, depression and deformation. The dimensional error is within the controllable range, and the incoming materials have original inspection reports and certificates. Those that need secondary inspection need to be rechecked by caliper, secondary element, thickness measuring instrument, power meter and other testing tools.

According to the principle of assembly, from the inside to the outside, 304 stainless steel screws are selected for assembly machine accessories, key switches, water tanks, radiators, electromagnetic valves, laser power supplies, etc. The length is appropriate, and spring pads and flat pads need to be installed, and the screws are firmly locked. Connect the finished wires to the devices, laser power supply, cooling system and control system in turn, and connect them according to the technical requirements. The terminals and forks need to be firm without looseness and virtual connection. Wire the power line and signal line separately, and fix them with tie straps to be uniform.

​​​​​​​ After the jewelry laser welding machine is assembled, it is necessary to pull the machine into a dust-free workshop, install, debug and test the optical devices, and test whether all functions are normal, and whether the laser light and software functions are normal. Use photo paper to check whether the optical shift is symmetrical and whether the laser energy meets the requirements after parameter setting. After everything is normal, it is necessary to test the light aging for 48 hours. The aging parameter is 200A 5MS 15HZ, and the changes of laser energy, water temperature, light output times and light class are monitored and recorded every hour.

After the aging test of the laser welding machine for jewelry is completed, it meets the delivery requirements. The quality inspection personnel will check all data of the laser welding machine according to the technical requirements and customer contract requirements, and issue the inspection report. The person in charge of logistics shall pack the jewelry laser welding machine and related accessories according to the requirements of the contract, do a good job in safety protection and fixation, seal the jewelry laser welding machine with international standard wooden cases, and stick the marks and logistics documents outside the wooden cases for logistics transshipment.

1. Jewelry laser welding machine has passed strict quality inspection, appearance, various functions, performance testing and instrument testing, and jewelry laser welding machine has begun to enter the packaging and delivery procedure. Drain the water tank of the machine first, and then move it to the bottom plate of the wooden box.

Adjust the position of the laser welding machine for jewelry, and keep the distance from left to right to back consistent. Spread a layer of foam cotton on the laser welding machine for jewelry, tighten it with a special packing belt, and lock it with a packing buckle. Note that the two packing belts are symmetrical and firm.

Check whether the nameplate and LOGO of the jewelry laser welding machine are properly attached, arrange the accessories of the jewelry laser welding machine, pack them in special accessories cartons, and fix the power cord on the rear door panel of the jewelry laser welding machine with tie straps.

Wrap the laser welding machine for jewelry with packaging film. The packaging film should be layered from bottom to top. The packaging film must be tightened to ensure a seamless seam. Every part should be wrapped in place, with at least three layers.

Nail the surrounding boards in turn with a nail gun. Pay attention to the proper location of the nails, and the distance is basically the same. The interior is filled with foam cotton for protection, and the jewelry welding machine is tightly wrapped, and then self-tapping screws are used at the bottom.

After the wooden box is fixed, it should be carefully checked to ensure safety and firmness. Paste the shipping mark and invoice information, and wrap the whole surface of the shipping mark with transparent tape.
Photographs should be taken at every link of packaging and delivery, and the logistics department should upload them to the company system for later inquiry. The business department shall send all the information and photos of packaging and delivery to customers in time, and explain the delivery information to customers so as to prepare for receiving goods in advance.
