Before the pressing plate group 5512 presses on the material belt, the limiting pin 572 is inserted into the feeding hole to adjust and position the material belt, and the limiting pin 572 prevents the material belt from moving when the micro tact switch is cut off from the material belt.

Referring to fig. 1 and 7, a supporting block 581 fixed with the bracket 51 is arranged on one side of the discharging end of the lower die body 52, a through hole 582 for the material belt to pass through is arranged on the supporting block 581, and a cutting component is arranged on one side of the supporting block 581 back to the lower die body 52; the cutting component comprises a cutting block 583 which is embedded on the supporting block 581 and is positioned below the through hole 582, a cutter 584 which is connected to the chassis base in a sliding manner along the vertical direction, and a fourth air cylinder 585 which is fixedly connected to the supporting block 581 and drives the cutter 584 to reciprocate along the vertical direction; a scrap leading-out pipe 586 is installed on one side of the supporting block 581 back to the lower die body 52, one end of the scrap leading-out pipe 586 covers the cutting assembly, the other end extends downwards, and a scrap collecting box 587 is arranged at an outlet of the scrap leading-out pipe 586. After the material belt passes through the through opening 582, the cutter 584 moves downward under the action of the third cylinder 552, so that the material belt is cut off by the cutting block 583, and the cut waste material falls into the waste material collecting box 587 through the waste material outlet pipe 586 and is collected uniformly.

In use, the tape passes through the tape channel, between the two platens 563 on the lower mold body 52, and through the port 582 in that order, and is intermittently moved by the drive mechanism 3. When the base on the material belt is positioned at the positioning mechanism 6, the primary assembly mechanism 4 can clamp the upper cover with the button on the base, so that a complete micro tact switch is formed; when the micro tact switch moves between the upper mold 551 and the lower mold 52, the secondary pressing mechanism 5 presses the hook on the upper cover to ensure the stability of the clamping between the upper cover and the base, then the punching blade 564 cooperates with the punching hole 562 to cut the micro tact switch off from the material strip, and the cut micro tact switch is collected in the collecting bucket.
