- Can’t boot normally
The measurement and control board and the charging circuit board have multiple faults. The side control board considers ventilation and heat dissipation issues.
Charging cannot be successful when the charging board is faulty and starts. There is a problem with the charging box, which causes a trip during startup. (Air switch jumps) The charging speed is slow when the device starts everything normally. The first pulse is very strong and the laser is continuously emitted and then becomes weaker. The above phenomenon can be repeated after a few seconds after stopping the pedaling. A single point is not easy to detect. There is a problem with the board quality. One hour after the power-on test, a “pre-combustion” error is displayed, the machine cannot work normally, and restarting is invalid.
- interference
After the startup of several machines, when the foot switch emits light, the screen automatically refreshes once and displays “water cooling error”, “charging error”, “pre-ignition error”, “module error”, and “start X”, that is, interference when stepping on the light After booting, “Start” cannot replace “√”, it needs to be restarted once. It may be that there is interference in the communication between the operation panel and the side control board. The machine shuts down automatically after running.
- Defocus failure
Defocus failure is a common and frequent failure.
After the machine is running, the defocus amount cannot automatically return to the zero position or the defocus amount is different from the spot effect produced by the original setting parameters. The defocus motor does not rotate and cannot automatically adjust the focus. The first startup is normal, the running program has different versions of the defocus motor control method, and the on-site service personnel cannot be notified in time, so that it mistakenly believes that there is a problem with the defocus amount, which is one of the reasons. When considering the alignment of the program, a written statement is issued to inform the service staff.
- Light spot
The main reason is that there is spatter when Jewelry laser welding machine, which causes losses to customers. There are burrs around the solder joints and is not smooth. When the defocus becomes larger, the spot has only a half circle. The lack of re-adjustment has been slightly improved, but users think it is different from other manufacturers (imported machines). User requirements:
The spot diameter changes with the defocus amount to have an obvious size indication, so that it will not cause damage to the jewelry.
- Charging voltage
The voltage is adjusted from a higher parameter to a lower voltage parameter. The output energy of the previous few times is still the output energy of the previous parameter, and then it is normal. This will cause the user to damage the jewelry when welding. Consider adding the first pulse suppression function where appropriate.
- flashlight. This problem is a longer problem reported by service personnel and customers
Insufficient light, severe fever. The brightness of the lighting lamp is not adjustable. The lighting increases the temperature in the operating room, causing serious deformation of the panel film. The installation position of the two spotlights is unreasonable, and it feels very dark when looking at the jewelry welding object during welding. The lighting is required to be white or yellow. Consider adding switch control for each lighting spotlight to appropriately reduce the heat generation of the lamp.
- Ventilation effect, users report expected problems
The setting of the ventilation position is unreasonable. The height of the ventilation hole and the welding surface should be the same. Now the ventilation hole is also located at the bottom of the welding surface, which affects the ventilation effect. The exhaust outlet is located at the bottom of the casing. When the user installs, the installation height is too low, which may also affect the exhaust effect, so you can consider exhausting from the side.
- programming
At present, the air blowing delay is controlled by the program. Each time the device is turned on, the program will restore the air blowing delay to the switch value set to 1S, that is, the light will be emitted after 1S of stepping on the foot switch. If the user is too slow to use, it must be modified each time the device is turned on. , Too much trouble. It can be considered: Not controlled by the program, use a double pole to connect the foot switch, blow air, and complete the foot switch once when the light is emitted. Consider replacing it directly: “Spot Diameter”.
- Joystick
It becomes loose after a few times of operation. This phenomenon is common, and the user wants to switch to a button or potentiometer to adjust.
- Beam expander. Two beam expanders are burnt out, and it is inconvenient to install and adjust the position.
- eyepiece
The vision range of the eyepiece is not large enough and unclear. There are often stains in the eyepieces, which are difficult to remove. Sometimes it is sent to the user and the user asks for replacement. inconvenient. The operators of some manufacturers work for a long time, which makes the eyes very swollen. It is recommended to install a protective cover on the eyepieces.
- refrigerating system
During the working process of the refrigeration system, the temperature setting is automatically converted to the factory setting (20 degrees). This phenomenon is more recurring. The refrigeration switch automatically turns off during the working process of the refrigeration system (it may be caused by the interference of the internal microcontroller). Some water tank compressors vibrate severely after starting. The pressure of the water pump of the refrigerator makes the water pipe easy to leak.
- Packing and shipping
The rear box of the machine is compressed and deformed when the goods are received. Consider adding a plastic bubble film to the space between the rear box and the charging and discharging box. To prevent deformation during transportation.
- other
Paste the film. There are gaps around the display screen, which feels very rough, and there are some parts where the panel buttons are hard and inflexible. The operating room is closed. In order to strengthen the sealing effect, we now use hot melt in the operating room and apply it in the gap. But it feels ugly when the small post is sent to the user (you can still see the situation in the production workshop). Two small bowls cannot be connected in series for the purpose of recovering gold. Try to ensure that the workbench is flat and seamless. The foot switch is not flexible enough and hard. The operator feels very uncomfortable to place the fulcrum on his hand, and the user requests that the welding focal length be longer. The customer suggested that the air valve control can control the size of the air pressure, that is, add a pressure regulator. The wiring of the lighting lamp should be specified in the chassis. The emergency stop button and key switch must have instructions. Do not expose the heat shrinkable tube at the junction of the observation window lamp. H, the machining gap is large and the capillary is fine. Some customers have replaced imported machines because they feel that the appearance is too poor.
About the daily maintenance of jewelry welding machine, maintenance knowledge
When the welding machine is used, the surrounding environment should be clean, there is more dust in the air, and the strong vibration should be kept away to avoid affecting the water and light path system. Use a separate air conditioner when possible. Room temperature has little effect on the welding machine, but it should be noted that pure water should be used when the water tank temperature cannot be set and used in the water phase, and the water quality should be checked every two weeks for odor, dirty, etc. In principle, the water should be changed every five weeks. According to the water quality, the surface of the welding machine can be cleaned, and there are dust and stains. At the same time, the upper cover of the welding machine should be opened to clean the outside of the laser cavity. One-time power-off requirement: the power can be turned off after the shutdown steps in the manual are completed. Try not to interrupt the power during the startup process, which will affect the life of the welding machine. To adjust the light path, the operator can use the photo paper to adjust the light path on request. In principle, the light path is adjusted once every six weeks. Clean the dust inside the vacuum cleaner. There should be a time interval of more than three minutes between each power-on and power-off. Ordinary power on and off will affect the life of the machine.
