1,焊接工件的工艺误区

口罩机超声波能量是瞬间爆发的,焊接线应成点或许线条以及传递的间隔都要契合超声波焊接方法。口罩机有人以为只需是塑料资料,无论怎样结合面都能够杰出的焊接,这是错的认知,当瞬间能量发生时,接缝面积越大,能量涣散越严峻,焊接作用越差,乃至无法焊接,别的超声波是纵向传波的,能量丢失同间隔成正比,远间隔应控制在7.5厘米之内。焊接线应控制在0.3-0.8mm之间为最佳状况,工件的壁厚不能低于2mm,否则不能杰出焊接,特别是要求水气密的产品。

1, the technology mistake of welding work piece

Mask machine ultrasonic energy is instantaneous, the welding line should be a point, perhaps lines and transmission intervals are consistent with the Ultrasonic welding method. Mask machine some people think that as long as the plastic material, no matter how the joint surface can be outstanding welding, this is wrong perception, when the instant energy occurs, the larger the area of the joint, the more serious the energy lax, the worse the welding effect, and even unable to weld, other ultrasonic wave is longitudinal transmission, energy loss is proportional to the interval, the far interval should be controlled within 7.5 cm. Welding line should be controlled between 0.3-0.8 mm for the best condition, the workpiece wall thickness can not be less than 2mm, otherwise can not be outstanding welding, especially the product that requires water and gas tightness.

2,工件资料误区

   口罩机超声焊接机对焊接的工件原料是有要求的,不是一切资料都能焊接,有人以为任何资料都能够焊接,这是一大误解,不同原料之间有的能杰出焊接,有的基本能熔接,有的是不相熔的。同一资料之间熔点是相同的,从原理讲是能够焊接的。但是当焊接的工件的熔点大于350度的时候,就不在合适超声焊接了。口罩机因为超声是瞬间使工件分子熔化,判断根据是在1-3之内,不能杰出焊接,就应该挑选其他焊接工艺,如热板,旋熔,振动冲突等。一般来讲ABS料是最简单焊接,因为熔点低,硬度也硬,反之尼龙是最难熔接的。

2, the error area of workpiece data

   Mask machine ultrasonic welding machine on the welding of the workpiece material is required, not all data can be welded, some people think that any data can be welded, this is a big misunderstanding, between different materials can be outstanding welding, some basic welding, some are immiscible. The same melting point between the same data is the same, from the principle that can be welded. But when the melting point of the welded workpiece is greater than 350 degrees, it is no longer suitable for ultrasonic welding. Mask machine because ultrasound is instant to make the workpiece molecules melt, judging according to is in 1-3, can not outstanding welding, should choose other welding process, such as hot plate, rotating melting, vibration conflict. Generally speaking, ABS material is the simplest welding, because the melting point is low, hardness is also hard, whereas nylon is the most difficult to weld.

3,超声波挑选误区口罩机

  运用多大输出功率,振动频率,振幅规模,要根据工件的资料,焊线面积,工件内是否有电子元器件,是否要气密等因从来考虑。误以为功率越大越好。这也是一个误解。如果对超声波不是很了解。最好请教正规的超声波出产厂工程技术人员。有条件的话最好到厂家现场交流,不要盲目遵从一些非正规超声出售人员的误导口罩机。现在出产相关设备的公司特别杂乱,其间大部分为家庭式作坊,对电路进行生搬硬套拷贝,对作业原理似懂非懂。拷贝出的设备有一下丧命缺点。其一是购买的原资料质量无法确保,其二出产工艺的核心技术没有把握。

   口罩机设备在中功率和大功率作业中常常体现不稳定,产品合格率低。有时设备损坏。如换能器功率变压器,所运用的磁性资料参数无法丈量,磁饱满磁通密度(Bs),磁感应强度(Bm),有效磁导率(Ue),剩下磁通密度(Br),矫顽力(A/M)等,绕制工艺适当杂乱,这些家庭式作坊是无法做到的。所以购买超声波,最好先了解一下公司情况,不要盲目遵从出售员吹捧,也不要只需价格。只要这样才干日后削减不必要的费事。口罩机

3,Ultrasonic mask machine for mistaken area selection

 

   How much output power, vibration frequency, amplitude scale, according to the workpiece information, wire area, whether there are electronic components in the workpiece, whether to air-tight and so on has never been considered. That the more power, the better. This is also a misunderstanding. If you don't know much about ultrasound,. It is best to consult the regular ultrasonic production plant engineering and technical personnel. Conditional words had better come to the factory on-site Communication, do not blindly follow some informal ultrasonic sales personnel misdirect mask machine. Now the production of equipment-related companies in particular disorder, during which most of the family-style workshops, the circuit copy copy copy copy, the principle of the operation seems to understand. The copied device has one fatal flaw. One is the purchase of raw material quality can not be assured, the other production process core technology is not sure.

   Mask machine equipment in the middle-power and high-power operations often reflect instability, low product pass rate. Sometimes the equipment breaks down. Such as transducer power transformer, the magnetic data parameters used can not be measured, magnetic full flux density (BS) , magnetic magnetic induction, effective permeability (UE) , residual flux density (Br) , coercive force (A/m) , etc. , these family workshops are impossible to do. So to buy ultrasound, it is best to first understand the company, do not blindly follow the sales staff to flatter, but also do not just price. If that's what it takes to cut down on the unnecessary.

4,超声波输出功率误区

   超声波输出功率巨细,同压电陶瓷片的直径和厚度,原料,规划工艺决议,换能器定型,最大功率也就定型了,衡量输出能量巨细是个杂乱的进程。不是换能器越大,电路运用功率管越多,输出能量就越大,它必需要适当杂乱的振幅丈量仪,才干精确丈量其振幅,因为大多数运用者对超神波常识不太了解,加上出售人员的误导,给消费者一个过错的知道,耗费电能多少并不能反映输出超声功率的巨细口罩机,如发生纵向能量低,而耗费电流大,只能说明设备的功率底下,无功率大之说。口罩机

4, ultrasonic output power error

Ultrasonic output power size, the same piezoelectric ceramic chip diameter and thickness, raw materials, planning process decisions, transducer shaping, maximum power is also shaping, measuring the output energy size is a chaotic process. It is not that the bigger the transducer is, the more power tubes are used in the circuit, the greater the output energy is. It must be measured accurately by a suitably cluttered amplitude meter, because most users do not know much about the common sense of the super-wave, coupled with the misdirection of the sales staff, to give consumers a wrong idea, the amount of power consumption does not reflect the output ultrasonic power of the huge thin mask machine, such as the occurrence of Longitudinal energy is low, but the current consumption is large, can only show the equipment under the power, the theory of high reactive power.

5,焊接原理上了解误区

    适当一部分从事多年超声焊接方面的人员,对超声能量传递有一种误解,口罩机以为音波在接触面进行焊接,其实是一种误解,真实的焊接原理是,换能器把电能转换为机械能后,通过工件物质分子进行传导,声波在固体中传导声阻远小于在空气中的声阻,当声波通过工件接缝时,缝隙中的声阻大,发生的热能适当大,温度首先到达工件的熔点,再加上必定的压力,使接缝熔接,而工件的其他部分因为声阻小,温度低不会熔接。其原理同欧姆定律相似。

5, understanding the misunderstanding of welding principle

   For those who have been engaged in ultrasonic welding for many years, there is a misunderstanding about the transmission of ultrasonic energy. The mask machine thinks that sound waves are being welded on the contact surface. In fact, it is a misunderstanding. The real principle of welding is that, the transducer converts the Electrical Energy into Mechanical Energy and conducts it through the material molecules of the workpiece. The sound resistance in the solid is far less than that in the air. When the sound wave passes through the joint of the workpiece, the sound resistance in the joint is large, and the heat energy produced is appropriately large, the temperature first reaches the melting point of the workpiece, and the necessary pressure makes the seam weld, while the other parts of the workpiece because of low acoustic resistance, low temperature will not weld. The principle is similar to OHM's law.

6、焊接结构的误区

   超声模具(Horn)型式多样,工件的形状决议模具外形,但每部分的尺度和弧度,原料都要严厉核算的,有人过错以为只不过是一个金属块而已。口罩机规划是否合理直接影响着模具的功率,寿数,产品的合格率,严峻时直接烧坏发生器。模具的资料一般运用镁铝7075,而有些人为降低成本,运用残次资料。正规模具出产商进料都有一套严厉地查验程序,加工尺度都是通过核算机软件模仿和校验后加工出来的。质量才有确保。这些工序一般作坊是无法做到的,不通过合理规划,做出的模具,在焊接小工件时,反响问题还不显着,当大功率时就会呈现各种坏处。严峻时直接损坏元器件。

6. Mistakes in welding structures

   Ultrasonic Die (Horn) a variety of forms, the shape of the workpiece shape mold shape, but every part of the scale and Radian, raw materials have to be strictly accounted for, some people mistake that it is just a piece of metal. Whether the mask machine plan is reasonable or not directly affects the mold power, the life number, the product qualified rate, when severe direct burn generator. Mold materials generally use magnesium 7075 aluminium alloy, and some people to reduce costs, the use of defective materials. Normal mold manufacturers have a set of strict inspection procedures, processing standards are through the computer software simulation and verification processing out. Quality is guaranteed. These processes can not be done in general workshops, not through reasonable planning, made the mold, in the welding of small parts, the response problem is not significant, when high-power will present a variety of disadvantages. Direct damage to components in severe conditions.
