the second step is that: after the product is blocked by the blocking cylinder, the controller controls the jacking cylinder to drive the platform scale to ascend to a lifting position, and the product is lifted upwards by the platform scale and leaves the conveying line;
the third step: the controller controls the X-axis moving module, the Y-axis moving module and the Z-axis moving module to drive the synchronous glue pouring device to move to the position above a product, and controls the laser displacement sensor to detect whether the product is horizontal, if not, the alarm gives an alarm, and if so, the controller controls the moving assembly to drive the synchronous glue pouring device to move to the position above the product;
the fourth step: the platform scale initially weighs the product; after weighing, the controller controls the pushing cylinder to simultaneously press each piston rod, the glue is discharged from each dispensing head, and meanwhile, the controller controls the moving assembly to drive the synchronous glue pouring device to move along a glue pouring track so as to pour the glue into the product;
the platform scale weighs the product in real time in the glue pouring process, after the glue pouring is finished, whether the glue pouring meets the requirement is judged according to the difference between the final weight and the initial weight of the product, if the glue pouring does not meet the requirement, the glue pouring is continued, and if the glue pouring meets the requirement, the controller controls the jacking cylinder to drive the platform scale to descend, so that the product returns to the conveying line, meanwhile, the blocking cylinder is released, and the product is continuously conveyed;
wherein, the encapsulating process of synchronous encapsulating device is specifically as follows:
firstly, glue is fed into a glue feeding channel, in a glue filling unit, glue sucking air valves of all glue filling mechanisms are synchronously opened, piston rods synchronously ascend, and therefore glue is synchronously fed into accommodating cavities of all the glue filling mechanisms;
then, when the accommodating cavities of the glue filling mechanisms are filled with glue, the piston rods synchronously stop rising, and the glue suction air valves of the glue filling mechanisms are synchronously closed;
then, the glue discharging air valves of all the glue pouring mechanisms are synchronously opened, and the piston rods synchronously descend, so that all the glue pouring mechanisms synchronously discharge glue to the corresponding glue dispensing heads;
and finally, synchronously stopping descending of each piston rod, and synchronously closing the glue discharging air valves of each glue filling mechanism so as to synchronously stop discharging the glue to the corresponding glue dispensing heads in each glue filling unit.
