At present, most of the devices on the market adopt a mode of hooking or clamping the carrier plate by using a hook claw or a clamping claw and dragging the carrier plate to move on a certain plane for transportation of the carrier plate;
the defects of the structural mode are as follows:
1. the structural mode is difficult to ensure that the carrier plate, the tray on the carrier plate and the materials can be stably stopped to be in a static state when the carrier plate moves to a specific position point; because the requirement on equipment precision is higher in production, a camera CCD is positioned before the suction nozzle sucks materials, when the carrier plate moves to a specific position point, the carrier plate, a tray on the carrier plate and the materials can move, and at the moment, the materials shot by the camera CCD are dynamic, photographing can be inaccurate, so that the phenomenon of deviation suction or incapability of sucking materials when the suction nozzle sucks materials is caused;
2. because the UPH of the equipment is very high and reaches more than 4000PCS/h, the carrier plate needs to frequently move back and forth, when the structural mode is adopted, the friction between the carrier plate and a contact plane of the carrier plate is frequent, dust can be generated, and because a client production workshop is a high-grade dust-free workshop, a dirty product is caused, and the cleanliness of the equipment does not reach the standard;
3. the structure is in a shaking state when the carrier plate moves, so that when the carrier plate moves to a specific position point, the deflection angle of the carrier plate is larger, and the angle of each position possibly reached is random, so that the rotating shaft (R shaft) of the suction nozzle structure rotates by a larger angle each time when the suction is carried out, and the longer the time required for the rotating action is, the lower the UPH of the equipment is.
