The glue liquid in the glue storage chamber is squeezed and exerts an upward reaction force on the movable sleeve, causing the movable sleeve to move upward, resulting in failure of the seal between the movable sleeve and the protrusion on the connecting rod. The glue liquid enters the glue discharge chamber area from the gap between the movable sleeve and the protrusion, and then passes through the glue discharge hole and the glue discharge channel and is discharged out from the glue discharge port on the cylinder sleeve.

In this process, the movable sleeve moves upward under the action of the raised part on the connecting rod and maintains the seal with the raised part, and the volume of the glue storage chamber gradually increases until the piston rod of the cylinder switches to a contracted state. When the piston rod of the cylinder transforms from a contracted state to an extended state, the movable sleeve first moves downward with the upper connecting shaft and the connecting rod to reduce the volume of the glue storage chamber. The glue liquid in the glue storage chamber is squeezed and exerts an upward reaction force on the movable sleeve, causing the movable sleeve to move upward, resulting in failure of the seal between the movable sleeve and the protrusion on the connecting rod. The glue liquid enters the glue discharge chamber area from the gap between the movable sleeve and the protrusion, and then passes through the glue discharge hole and the glue discharge channel and is discharged out from the glue discharge port on the cylinder sleeve.

[0033] The above-mentioned large-flow pneumatic pressure plate glue supply pump is adopted, which drives the staggered connection between the glue inlet chamber, the glue storage chamber and the glue outlet chamber through the reciprocating movement of the upper and lower connecting shafts, so as to realize the continuous supply of glue at a large flow rate to ensure the demand for glue consumption on the photovoltaic production line, and also ensure the stability of the output glue pressure and flow, thereby ensuring the quality of the final glue dispensing.
