双组份打胶机必须遵循的几大流程
一、点胶量的大小是由全自动双组份打胶机在点胶过程中持续的时间长短来决定的,可以保证有足够的胶水来粘合部件,同时可以避免胶水过多而造成的资源浪费。
1、 The size of the dispensing amount is determined by the duration of the automatic two-component dispenser in the dispensing process, which can ensure that there is enough glue to bond the parts, and at the same time, it can avoid the waste of resources caused by excessive glue.
二、真空回吸阀必须要安装在全自动点胶机上,由于真空回吸功能是防止点胶机中的胶水在不点胶时还在滴漏。
2、 The vacuum suction valve must be installed on the automatic dispenser, because the vacuum suction function is to prevent the glue in the dispenser from dripping when not dispensing.
三、在全自动双组份打胶机行业中通常使用的胶水大概有硅胶、瞬间胶、厌氧胶、环氧树脂、UV胶。
3、 In the automatic two-component gluing machine industry, the commonly used glue is silica gel, instant glue, anaerobic adhesive, epoxy resin, UV glue.
四、固化因素:对于胶水的固化,一般生产厂家已给出温度曲线。一般在常温下都可以固化,在实际应尽可能采用较高温度来固化,使胶水固化后有足够强度和硬度。
4、 Curing factor: for the curing of glue, the general manufacturer has given the temperature curve. Generally, it can be cured at normal temperature. In practice, it should be cured at a higher temperature as much as possible, so that the glue has sufficient strength and hardness after curing.
五、针头的规格与类别:针头的规格会影响点胶机在点胶过程中出胶的大小和精密度,当气压在一定范围时,针头的咀越大,出胶率就越大,所以要根据点胶机在生产出来产品的大小来定位点胶针头的规格,一般针头内径长度保持在胶点直径的一半,效果才是更好。
5、 Size and type of needle: the specification of the needle will affect the size and precision of the dispensing machine in the dispensing process. When the air pressure is within a certain range, the larger the nozzle of the needle, the greater the glue yield. Therefore, the size of the dispensing needle should be positioned according to the size of the product produced by the dispenser. Generally, the effect is best when the inner diameter of the needle is kept at half of the diameter of the glue point.
六、压力的大小直接影响了供胶量和胶水流出的速度,胶水的流动性越差它就越稠,全自动双组份打胶机需要的压力就越大,所以我们应该根据全自动点胶机在生产过程中的环境温度以及点胶量的大小和胶水的特性来调节压力的大小,全自动点胶机的压力大小是通过它内部的调压阀来进行调节的。
6、 The pressure directly affects the amount of glue supplied and the speed of glue flowing out, The worse the fluidity of the glue is, the thicker it will be, and the greater the pressure required by the automatic two-component dispenser. Therefore, we should adjust the pressure according to the ambient temperature of the automatic dispenser in the production process, the size of the dispensing amount and the characteristics of the glue. The pressure of the automatic dispenser is regulated by its internal pressure regulating valve.
七、气泡对于全自动双组份打胶机在进行点胶过程中会影响产品质量,所以胶水放进去之前决对不能有气泡.如果有气泡就会造成点胶机生产出来的产品有许多次品,在使用中要排出胶水的空气,以防止出现全自动点胶机空打现象。
7、 Bubbles will affect the quality of the products in the dispensing process of the automatic two-component dispenser, so there must be no bubbles before the glue is put in. If there are bubbles, there will be many defective products produced by the dispenser. During the use, the air of glue should be discharged to prevent the phenomenon of empty tapping.
