Specifically, the operation process of the full-automatic rubber sleeve positioning and mold entering system a is divided into two sections:
in the first stage, a front positioning mechanism a6 and a rear positioning mechanism a7 in a gum cover positioning mechanism a2 are driven by a driving motor, and are combined to a guide mechanism a5 until the gum cover positioning mechanism a5 is contacted with the guide mechanism, so that the gum cover positioning mechanism a2 is ready to be molded. At the moment, two door seal gum covers are simultaneously conveyed to a preset position from two belts a12 in the gum cover conveying mechanism a3, the preset position is set through a photoelectric switch, and after the gum covers reach the preset position, the gum cover conveying mechanism a3 stops. At this time, three material shifting cylinders a17 in the rubber sleeve mold-in mechanism a1 act simultaneously to pull the two rubber sleeves to the left and right respectively to the specified positions, and the specified positions are preset through the positioning strips a15 so as to be guided into the mold. Then, the material pushing module a21 pushes forwards to drive the material pushing connecting rod a19 and the material pushing block a20 to push forwards at a constant speed, and after the material pushing connecting rod a19 and the material pushing block a20 run for a certain distance, the material pushing connecting rod a contacts with the material poking cylinder a17 and is linked forwards together until the material pushing connecting rod contacts with the rubber sleeve. At this time, the servo motor controls the forward mold-entering distance to be equal to the total length of the combined front positioning mechanism a6, rear positioning mechanism a7 and guide mechanism a5, so that the rubber sleeve mold-entering is completed.
In the second stage, after the gum cover is completely inserted into the mold, a rear positioning material pressing cylinder a46 in the rear positioning mechanism a7 acts to drive a rear positioning material pressing sheet a47 to press the gum cover, then a rear positioning driving motor a49 drives a rear positioning gear a50 to be in transmission with the rack, and the rear positioning mechanism a7 is moved to a preset position, wherein the preset position is a distance which is half of the length of the current gum cover from the center of a positioning bottom plate a8, and then the rear positioning material pressing sheet a47 rises and releases. In this process, to prevent the front positioning mechanism a6 and the rear positioning mechanism a7 from colliding, the front positioning mechanism a6 lags the rear positioning mechanism a7 for two seconds and starts to move together in the same direction to a predetermined position, which is the total length distance from the rear positioning mechanism a7 rubber sleeve. At this time, the front positioning mechanism a6 and the rear positioning mechanism a7 respectively position the front end face and the rear end face of the rubber sleeve, and the front end face and the rear end face are symmetrical with the two central ends of the positioning bottom plate a8 to wait for the mechanical arm to grab. When the manipulator descends to a preset position which is specifically set according to the cross section height of the rubber sleeve, in the rear positioning mechanism a7, the two rear positioning opening and closing cylinders a42 move to open the rear positioning opening and closing cylinders a40, so that the rubber sleeve is conveniently grabbed and moved out by the manipulator. After the rubber sleeve is moved out, the front positioning mechanism a6 and the rear positioning mechanism a7 are merged to the guiding mechanism a5 again until the rubber sleeve contacts and enters a state to be molded, and then the rubber sleeve conveying mechanism a3 operates again to convey the rubber sleeve, and the mold entering and the positioning are repeated.
In the whole process, the front positioning anti-deviation cylinder a32 in the front positioning mechanism a6 drives the front positioning anti-deviation block a33, the left side and the right side of the front positioning mechanism are symmetrically closed, the situation that a rubber sleeve deviates and even falls off in the whole moving positioning process is avoided, the same parts in the rear positioning mechanism a7 have the same functions, and the details are omitted.
