The elements that should be paid attention to when choosing a fully automatic folding machine

The diameter of the glue dot of the automatic paper folding machine should be half of the pad spacing, and the glue dot diameter of the automatic paper folding machine should be 1.5 times the diameter of the glue dot after patching. In this way, it can ensure that there is sufficient glue to bond the components and avoid excessive glue soaking the pad. The amount of glue for the automatic paper folding machine is determined by the rotation time of the screw pump. In practice, the rotation time of the pump should be selected according to the production situation.


If the back pressure of the glue is too large, the glue will overflow and the amount of glue will be too much; if the pressure is too small, the glue dispensing of the automatic origami machine will be intermittent, leaking, and causing defects. The pressure should be selected according to the same quality glue and working environment temperature. A high ambient temperature will make the glue of the dispenser reduce its viscosity and improve its fluidity. At this time, it is necessary to lower the back pressure to ensure the supply of glue, and vice versa.

 In actual work, the inner diameter of the needle should be 1/2 of the diameter of the glue dot of the automatic origami machine. During the dispensing process, the glue needle should be selected according to the size of the pad on the PCB, such as the pad size of 0805 and 1206 The difference is not big, you can choose the same needle, but for the pads that are very different, you must choose different needles, which can not only ensure the quality of the glue dots of the automatic origami machine, but also improve the production efficiency.
