In the production process of the power supply, the use of plastic welding can make the performance of the power supply easier and make the product stronger and more durable. Today, the power supply defense will share with you how to perform plastic welding.
Preparation before homework:
1. Wear earplugs;
2. Notify ME technicians to connect the equipment, assemble the corresponding parameter mold, and try to install the equipment to work 22-5PCS. After the drop test is done by IPQC and the appearance is confirmed, it can be mass-produced;
3. Instruct the operator to operate the equipment
work procedure:
1. Reclaiming inspection: take the product, check the surface of the product, the color is uniform, there is no bad defects such as color difference, and it is highly opaque, highlighting the PCB board raw materials;
2. Homework:
① Check that the power supply and pipe of the nozzle machine are connected correctly, the mold parameters are correct, and the vivid working parameters are adjusted correspondingly (ME technicians can set the parameters according to the actual situation);
②Take the last processed product from the PCB, check that the upper and lower shells of the product are not vacuumed, do not pretend, or sign, sign a statement, close the product hardware mold pins and contact the live broadcast lower slot, confirm that it is still, press at the same time Press the two green buttons to perform welding;
③Standardize safe operation to ensure that the product welding has no major problems, no injuries, no glue overflow, no pressure PE bag, no misalignment and other appearance defects. If the defects are picked out, isolate and notify the ME technician for fate;
3. Visual welding inspection line: After inspecting the product information after welding, there is no big, no injury, no misalignment and other adverse events, and then follow the flow direction, and broadcast the next visit on the spot.
Precautions:
1. The operator’s job certificate is used for multi-person operation with one-handed operation, holding crushed hands;
2. When installing the product, you must ensure that the upper and lower shells of the product are qualified, and the hardware pins rise into the fixed mold to keep it stable and not loose;
3. The upper mold that must be drawn must be filled with a transparent film, and a verification is required after the 10PCS product is transmitted, and the IPQC needs to check the effect of the error (5PCS/H);
4. Work, handle with care, receive the notice, and do the 7S work in the work area.
