In the use, can install feed bin 50 earlier, once tear 25 packet callus on the sole open, can hold 500 callus on the sole, adopt the robot (the clamp in this embodiment gets structure 30 can be the robot) and arrange visual system and carry out the accurate material of getting. The material taking machine is started by one key, can take pictures visually, can be clamped automatically, does not need manual participation, and can efficiently finish the material taking task. The feeding bin 50 for placing 25 foot pads can be manually placed at one time, the number of the foot pads is up to 500, and the foot pads are prevented from being frequently unpacked and taken manually. The robot is matched with the vision system to replace manual operation, so that the efficiency is high, the precision is high, and the beat of the product is fast.
There is a discharge port above the bin 50 and the vision system is mounted directly above the discharge belt. The human body can place 25 foot pads at one time, namely 500 foot pads. When the equipment is started to operate, the equipment can be started by pressing a start button by one key manually. When the robot runs to a waiting point, the vision system starts to shoot, and the foot pad with the set model is automatically captured within a certain vision range. When no foot pad exists in the visual range, the discharging belt rotates, the foot pad in the bin 50 falls onto the discharging belt, and the belt stops rotating until the foot pad enters the visual system range. When materials exist in the shooting range of the vision system, the postures of the foot pads are obtained through the vision through shooting, the templates set by the vision are compared, and the foot pads which accord with the grabbing operation postures of the robot are automatically screened out. And then sending the data to the robot through the Ethernet, assigning the data to a grabbing point, and moving the robot from the waiting point to the grabbing point for grabbing. After the grabbing action is finished, the robot judges whether the material is stored on the buffer belt or not. If the belt is full of materials, the robot runs to an excessive point to wait, and the vision is started again to take pictures (providing data coordinates for next grabbing and reducing station beats). If the belt is not full of material, then the robot moves to the point of placing, places the callus on the sole on the belt, transports the callus on the sole by the buffer memory belt and places the automatic grabbing point of equipment of callus on the sole. After the robot finishes placing, the robot moves to a waiting point, and the vision shooting finishes the cycle work.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: the efficiency of snatching of callus on the sole is improved.
