Before the production of automatic filling machine and dispensing machine, packaging equipment should be selected according to the actual requirements of packaging. Storage, defrosting, heating, stirring and drying of liquid materials are also factors requiring special attention.

　　在自动灌装机和分配器包装前，我们通常将物料放入一个特殊的压力桶中。在包装设备的驱动下，液体物料将被排出。为了起见，通常将液体物料储存在所有生锈钢的压力桶中。一般需要配备必要的气压计、搅拌系统、液位报警显示系统等设备。为了防止液体物质的泄漏，我们必须确保压力桶具有良好的气密性。市场上常用的压力桶是略小的2L、3L、5L、略大的10L、20L。

　　Before the automatic filler and distributor are packed, we usually put the material into a special pressure barrel. Driven by packaging equipment, liquid material will be discharged. For safety, liquid materials are usually stored in all pressure drums of rusty steel. In general, it is necessary to equip with barometer, mixing system, liquid level alarm display system and other equipment. In order to prevent the leakage of liquid substances, we must ensure that the pressure barrel has good air tightness. The commonly used pressure barrels on the market are slightly smaller 2L, 3L, 5L, slightly larger 10L, 20L.

　　在包装过程中，胶水中的气泡会对包装质量产生严重的影响。因此，自动点胶机、灌装机与常规UV胶、导电胶包装时，必须进行凝胶除霜处理。所谓除霜过程的目的是将凝胶内的气泡减少到接近0。外部真空泵通常用于去除气泡。随着真空泵设备技术的不断改进，无油真空泵已经能够帮助减少流体中的气泡，解决噪声问题。

　　In the packaging process, the bubbles in glue will have a serious impact on the packaging quality. Therefore, the automatic dispensing machine and the filling machine must be treated with gel defrosting when packing with conventional UV adhesive and conductive adhesive. The purpose of the so-called defrosting process is to reduce the bubbles in the gel to nearly 0. External vacuum pumps are usually used to remove bubbles. With the continuous improvement of vacuum pump equipment technology, oil-free vacuum pump has been able to help reduce bubbles in fluid and solve the problem of noise.

　　时间压力:这是目前应用广泛的技术。它是随着SMT技术的发展而引进的个技术，并被业界广泛接受。它也有较长的历史比其他配药技术。

　　Time Pressure: This is the most widely used technology at present. It is the first technology introduced with the development of SMT technology and widely accepted by the industry. It also has a longer history than other dispensing techniques.

　　其主要优点是:结构和原理简单，使用和维护成本低;更换桶针方便，通过更换零件可以滴下不同量的胶水;设备清洗保养方便;该系统具有灵活性，适用于不同粘度的胶液。

　　Its main advantages are: simple structure and principle, low cost of use and maintenance; convenient replacement of barrel needles, different amounts of glue can be dripped by changing parts; easy cleaning and maintenance of equipment; flexible system, applicable to different viscosity glue.

　　缺点:胶料由空气脉冲推动，分胶周期较长。因此，在高速点胶时，速度有限，一般可达每小时40000点，随着点胶速度的增加，很难保证点胶点的一致性:每次点胶时，物料桶内的点胶液全部被压缩;

　　Disadvantage: The rubber is driven by air pulse and has a long separating period. Therefore, when dispensing at high speed, the speed is limited, generally up to 40,000 points per hour. With the increase of dispensing speed, it is difficult to ensure the consistency of dispensing point: every dispensing time, the dispensing liquid in the material barrel is compressed;

　　料筒胶量的不同使其对空气脉冲的反应不同，胶点不一致;如0805或0603包装的胶点很难滴出，如果包装达到0402或更少，则该技术无法做任何事情。

　　The different amount of glue in the barrel makes its reaction to air pulse different and the glue points are different. If the glue points of 0805 or 0603 packaging are difficult to drip out, if the packaging reaches 0402 or less, the technology can not do anything.
