Ultrasonic Car Charger Welding Machine

In ultrasonic industrial applications, the majority of equipment used is ultrasonic welding machines. One reason is that ultrasonic welding machines are professional and have rich functions, suitable for various fields. The second reason is that ultrasonic welding machines can be used well in conjunction with assembly lines. The principle of an ultrasonic welding machine is the same as that of an ultrasonic manual welding gun, where electrical energy is converted into mechanical energy through an ultrasonic generator (intelligent electrical box). The difference lies in the fact that the ultrasonic welding machine includes a body, a frame, a machine head, and an intelligent electrical box, and can be equipped with larger fixtures with more stable parameters, which can be well applied to different scene fields. Moreover, ultrasonic welding technology does not require the addition of any auxiliary materials, making it very friendly for dust-free workshops.

Five safety precautions to strictly follow when using Ultrasonic Car Charger Welding Machine

1. Do not disassemble or replace the transducer when the machine is powered on.
2. Select the corresponding welding mold according to the structural dimensions of the product that needs to be welded.
3. During work or testing, do not allow the welding mold to directly touch the machine's base or metal fixtures.
4. If abnormal noise is found during operation or the energy exchange system heats up to 50 ℃ or above, work should be stopped immediately and reported to on-site management personnel.
5. Ensure that the workbench is clean and free of small particles to avoid affecting welding quality.

Debugging steps for Ultrasonic Car Charger Welding Machine

• Step 1: Conduct a mock test first

Press the check button on the ultrasonic welding machine chassis to emit ultrasonic waves. After checking that the current is normal and the sound is clear without any problems, install a new mold. Tighten with a hook wrench! If the mold is not tightened, long-term ultrasonic operation will cause oscillation of the gap at the joint, energy cannot reach below, and there are a series of problems such as excessive current power, which will damage the welding head and equipment.

• Step 2: Upper mold test

After the mold is installed, press the check button on the chassis again to check if the ultrasonic current is normal and the sound is clear. After completing these two processes, there is no problem with the ultrasonic wave emitting sound waves, and then the mold adjustment is carried out.

• Step 3: Adjust the height of the machine welding head

Adjust the height of the frame. When the welding head is lowered to the lowest position, the welding surface of the mold is about 5 millimeters lower than the surface of the plastic part. Before adjusting the rack, loosen the two locking wrenches of the rack, otherwise the motor will burn out. After adjusting, lock it. Adjust the height of the frame to ensure that the cylinder can press against the product during the ultrasonic plastic welding process. Also, please note that this is the limit of the cylinder. There is a screw at the top of the cylinder. Try fixing the screw at the top so that the cylinder can operate in the buffer zone. Therefore, welding must be carried out in the buffer zone of the cylinder.

• Step 4: Mold adjustment

Adjust the balance of the mold and fix the bottom mold. When adjusting, send out the four positioning screws, set the air source to zero, naturally press the mold onto the product, and then press the red button. Apply 0.1 megapascals of pressure to compress the product, visually inspect for flatness and tightness, manually adjust it, and then investigate the pressure by adding 0.1 megapascals of air source compression. After confirmation, fix the pressure at 0.4 megapascals (usually 0.4 megapascals according to the product). Finally, secure the four fixing screws (it is recommended to tighten them by hand). Press the bottom of the product tightly. Press the welding head down button on the chassis, then press it a few more times to lift the welding head and check if the mold is closed.

• Step 5: Adjust device parameters

1. Time format: Depending on the material, process, etc., it is possible to adjust the pre-vibration/delayed vibration, and adjust the vibration timing. The delayed vibration time is the delay time after the start button because the pressure of the cylinder varies in length. If there is no delay time, ultrasound will be sent directly after startup, which will lead to energy loss and more noise.

2. The second welding time is based on the product's ultrasonic control time.

3. The holding time is the time when the product is pressed after ultrasonic welding. Due to the elasticity of some of the plastic in the product, the temperature rises after welding. If the product is not pressed, it will immediately produce problems such as warping and deformation, but there is almost no problem. It can be appropriately set to 0-10.

• Step 6: Conduct experimental welding.

There is no problem with adjusting the general mold, just adjust the air pressure and welding time at the same time. If there are burrs on one side after welding, please adjust the balance nut and push up (tighten) the horizontal adjustment nut appropriately in areas with more burrs. After adjustment, there may be situations where the mold does not fit properly. All you need to do is loosen the bottom mold, release the air source, and recalibrate it once
