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.

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. The overall design is divided into up-and-down and left-and-right structures, with the laser power supply on the left side, the cooling system on the right side and the partition in the middle, which is convenient for installation and maintenance. The optical components are on it, which is convenient for installation, debugging and maintenance. The interior is sealed and dustproof, and the optical lens is not polluted by external flying dust and dust.

YAG laser adopts full cavity water cooling to facilitate good heat dissipation, and the cavity adopts quick connector to facilitate disassembly. The cavity is positioned by positioning pin, and the laser energy will not be affected if it is disassembled and put back.

the casing is made of 304 stainless steel and welded, with a thickness of 1.5mm, which can resist general external force strike or impact. It is made of corrugated paint, baked and shaped at high temperature, light gray, simple and elegant, noble and elegant, which makes the laser welding machine for jewelry more advanced.

it has the function of automatically adding water and stopping when the water is full, which is more convenient for daily use; Water pressure and water temperature alarm function to better protect the normal operation of the machine; Rocker parameter adjustment function, when our hands are working in the operation space, we can adjust the laser welding process parameters such as current, pulse width, frequency and light shift through the rocker.

Considering that some customers are not used to using a microscope, the imaging function of CCD is increased, and the magnification is 40 times to assist customers in fine welding. The CCD adopts a 1080P high-definition camera, which has high resolution and effectively reduces the fatigue of glasses. Microscope +CCD gives customers one more choice to observe welding.

According to customer feedback, the xenon lamp of DH LASER jewelry laser welding machine can be used for 24 months, the machine life is 6-10 years, and the failure rate is less than 2%.

DH LASER will continue to optimize and upgrade, accept the opinions of customers, improve the application environment of laser welding machine for jewelry, and create higher value for customers and friends.
