1.打胶机：针头和塞子的弯曲或磨损会对点胶质量产生重大影响。如果温度高或长时间不清洗，贴片胶也可能在针头内表面固化或半固化，造成堵塞。定期检查打胶机头，发现污染，及时清理。将针头浸泡在兼容的溶剂中是一种常见的方法，但单独浸泡的效率太低，无法去除所有未固化的材料。可以用兼容溶剂的高压喷雾将胶水从针头内孔吹出，然后用干燥的压缩空气将胶水吹出内孔，使针头干燥。

1. glue applicator: the bending or wear of the needle and plug will have a significant impact on the dispensing quality. If the temperature is high or it is not cleaned for a long time, the patch adhesive may also solidify or semi solidify on the inner surface of the needle, causing blockage. Regularly check the glue applicator head, and clean it up in time if any pollution is found. Soaking the needle in a compatible solvent is a common method, but soaking alone is too inefficient to remove all uncured material. The glue can be blown out of the inner hole of the needle with a high-pressure spray of compatible solvent, and then the glue can be blown out of the inner hole with dry compressed air to dry the needle.

2、金属模板：为了避免清洁剂侵蚀模板和丝网的粘合剂，使用预洗工艺，使用更强的清洁剂，手动操作，避免清洁剂和粘合剂接触，然后清洗模板用普通洗涤剂。

2. Metal formwork: in order to avoid the adhesive of formwork and wire mesh eroded by detergent, use pre washing process, use stronger detergent, operate manually to avoid the contact between detergent and adhesive, and then clean the formwork with common detergent.

3、塑料网板：清洗塑料网板时，可能会发生静电放电。因此，应使用特殊的抗静电清洁剂来避免这种现象。同时，不要用抹布用手清洁，因为塑料很容易划伤，长此以往可能会造成打印质量问题。点胶机的清洁是点胶机日常维护中的一项重要工作。用户对此非常重视，但清洁方法仍需改进。

3. Plastic screen: electrostatic discharge may occur when cleaning the plastic screen. Therefore, special antistatic cleaners should be used to avoid this phenomenon. At the same time, do not use a rag to clean by hand, because the plastic is easy to scratch, which may cause printing quality problems in the long run. The cleaning of dispensing machine is an important work in the daily maintenance of dispensing machine. Users attach great importance to this, but the cleaning method still needs to be improved.

4、双组份打胶机出胶时，应有一定成分，使新胶管中的胶水能顺利流出胶头。公认胶阀的压力和速度是按理想情况设定的。然后测量胶体流速，直到连续两次测量的误差在计划的正负2%范围内。

4. When the two-component glue applicator delivers glue, it should have certain ingredients to make the glue in the new hose flow out of the glue head smoothly. It is generally accepted that the pressure and speed of the rubber valve are set according to the ideal situation. Then measure the colloid flow rate until the error of two consecutive measurements is within the planned range of plus or minus 2%.

其余还应注意，如遇以下情况，建议不要使用粗略的纯胶管更换方法：胶管内的胶水在点胶机运行过程中已经用完。在这种情况下，分配阀很可能有大气。软管中的胶水已超过使用时间。在上述情况下，您需要彻底清洁刚性分配阀或分配泵，并按照设备程序进行操作。

It should also be noted that in the following cases, it is recommended not to use the rough replacement method of pure rubber hose: the glue in the hose has been used up during the operation of the dispenser. In this case, the distribution valve is likely to have atmosphere. The glue in the hose has expired. In the above cases, you need to thoroughly clean the rigid distribution valve or distribution pump and follow the equipment procedures.

5、快干胶（速干胶）堵在灌胶机胶阀的连接头和管路上：这种情况主要是体内水分过多或快干胶多次重复使用，应使用新鲜的速干胶。对于干胶，用体内不含水分的甲苯彻底清洗管道。应用的气体应彻底干燥，过滤装置应在出厂时在气压和阀门系统软件之间进行修改。

5. The quick drying glue (quick drying glue) is blocked on the connector and pipeline of the glue valve of the glue dispenser: This is mainly due to excessive water in the body or repeated use of the quick drying glue. Fresh quick drying glue should be used. For dry glue, thoroughly clean the pipe with toluene that does not contain water in the body. The applied gas shall be thoroughly dried, and the filtering device shall be modified between the air pressure and the valve system software at the factory.
