Step 1: Reasons affecting the ultrasonic product processing of plastic parts
1 ）焊头的振幅（ 2 ）接触面的设计（ 3 ）焊接压力、时间参数的选择（ 4 ）校模的准确性（ 5 ）焊接面与焊头之间距离（ 6 ）塑料材质（ 7 ）焊接线的设计（ 8 ）塑料件外形和尺寸（ 9 ）焊头的设计 ( 1 ) The amplitude of the welding head ( 2 ) The design of the contact surface ( 3 ) The selection of welding pressure and time parameters ( 4 ) The accuracy of the calibration ( 5 ) The distance between the welding surface and the welding head ( 6 ) Plastic material ( 7) ) Welding line design ( 8 ) Plastic parts shape and size ( 9 ) Welding head design
Step 2: Precautions for installing the mold of ultrasonic plastic welding machine
In order to achieve high production efficiency, the distance between the welding head and the plastic parts should be shortened as much as possible, but there should still be enough space for easy access to the plastic parts. In order to make the best use of the ultrasonic plastic welding machine, maintain the performance and safe production of the welding machine, every time the machine is used or the welding mold is changed, the vibration level of the vibration system and vibration system of the ultrasonic plastic welding machine must be adjusted The sonic detection procedure is very important.
Step 3: Install the ultrasonic plastic welding machine mold
The ultrasonic plastic welding machine installs the mold corresponding to the plastic part and its supporting parts. During the installation, it is installed according to the welding requirements of the plastic part. During the installation, leave some adjustment space for the next debugging of the mold, such as the fastening screws of the mold and the air pipe Connectors, etc. In this installation process, it should be noted that the installation of the mold must be prepared for future debugging welding.
5 大步骤 Step 4: 5 steps to install ultrasonic plastic welding machine mold
、将塑料件放在底座中调整气压在 2Kg 左右，利用焊头升降开关来使上下摸对准。 1. Place the plastic parts in the base to adjust the air pressure to about 2Kg , and use the welding head lift switch to align the top and bottom.
、调整限位螺栓使焊头下降压紧塑料件之后仍有 0.2mm 左右的空间。 2. After adjusting the limit bolt to make the welding head lower and press the plastic parts, there is still about 0.2mm space. (For plastic parts with higher welding depth requirements, this space is correspondingly increased).
、调整焊接、保压时间、气压、试焊样件。 3. Adjust welding, holding time, air pressure, and test welding samples.
、选择适合的焊头与塑料件之间的距离锁紧机架固定把手。 4. Select a suitable distance between the welding head and the plastic part to lock the frame fixing handle.
、观察样件 , 如发现焊接不均匀 , 则需要细调底座的平衡 , 一般原则为焊接部位熔接越厉害 , 则应调低，在底座相反位置垫上纸片等抬高底座对应位置，使塑料件与焊头吻合良好。 5 , observe the sample , if you find that the welding is uneven , you need to fine-tune the balance of the base . The general principle is that the more welded the welding part , the lower it should be. The parts fit well with the welding head.
Step 5: Before testing the ultrasonic plastic welding machine mold
、上焊模与超声振头两者必须密合锁紧，检验时上焊模切勿接触工件。 1. Both the upper welding die and the ultrasonic vibrating head must be tightly locked. Do not contact the workpiece with the upper welding die during inspection.
、合上电源开关，此时电源指示灯亮 . 2. Close the power switch, and the power indicator is on .
、打开侧盖板之门页。 3. Open the door of the side cover. 3 秒。 Press the selection switch to the position of the sound wave detection position and observe the value indicated by the amplitude meter. Each time the sound wave detection switch cannot be pressed continuously for more than 3 seconds.
、顺逆旋转音波检测螺丝使振幅表指针在最低刻度值位置。 4. Rotate the sonic detection screw forward and backward so that the pointer of the amplitude meter is at the lowest scale value. 1.2 （或 100 ）刻度值以下，且确保为最低刻度位置，焊机的发振系统与振动系统谱振最好。 Note: The pointer of the amplitude meter can be adjusted below the 1.2 (or 100 ) scale value and ensure the lowest scale position. The vibration system of the welding machine and the vibration system have the best spectral vibration.
