Detailed Description
Example (b): referring to fig. 1, the automatic cutter sharpening system provided by the invention comprises a knife sharpener and a manipulator communicated with the knife sharpener, wherein the knife sharpener comprises a sharpener body, a grinding wheel fixing device 1, a cutter fixing device and an air cylinder for pushing the cutter fixing device are arranged on the sharpener body, and a grinding wheel warehouse 2 is fixed on the grinding wheel fixing device.
The system also comprises a control system, wherein the control system comprises a control module, and a zero resetting module, a grinding wheel library module, a parameter modeling module, a speed setting module and a motion module which are connected with the control module, wherein the zero resetting module is a starting module in the system and is responsible for checking the safety condition of equipment, recovering and recording the position of a shaft, resetting an air cylinder and other functions. After the return-to-zero module operates, firstly checking whether the air pressure and the safety door are in a safe state, then checking the position of the air cylinder, and if the air cylinder is not at the starting position, operating the air cylinder; and finally, zeroing each axis according to the sequence, and recording the current position of each axis. If the cylinder acts and each axis is abnormal in the zero resetting process, the equipment can prompt, manual processing is needed, then the zero resetting module is continuously executed, and the next step of work can not be carried out until the zero resetting is successful, wherein the zero resetting module is shown in fig. 4.
And the grinding wheel library module. Because different cutters are polished, the shapes of the used grinding wheels are possibly different, and the grinding wheel library module can enable a customer to conveniently, quickly and correctly call the grinding wheels. The grinding wheel library module is realized by a method shown in 5, grinding wheels are classified, such as E4, DR, DL, OS and the like, and then the same grinding wheel is classified into materials: grinding high speed steel and grinding tungsten steel; meanwhile, each grinding wheel and the parameters are displayed by corresponding pictures, so that different grinding wheels are visually distinguished; and finally, the grinding wheel name and the use times of the grinding wheel can be modified, so that a user can distinguish different grinding wheels.
The parameter modeling module is a main module in the system, and performs geometric calculation by combining grinding wheel parameters, processing parameters, mechanical parameters and detection parameters to finally obtain an accurate detailed coping tool path. The parametric modeling module is actually a geometric computation module, which contains a number of mathematical algorithms. The module implementation method is as shown in fig. 6, after a result is obtained through a geometric algorithm, a path which a cutter travels is planned after a position of a grinding wheel is set for grinding, the path is decomposed step by step and then connected, and a whole grinding tool path is formed. When planning a path, attention needs to be paid to the selection direction of the grinding wheel, and attention needs to be paid to an avoidance area of the grinding wheel at the same time, so that cutter collision is avoided.
The speed setting module carries out speed planning on each grinding path after all paths of the grinding cutter are obtained. When the grinding is needed, the speed needs to be slowed down a little; when the grinding wheel grinds the cutter, the grinding speed is a little faster when the grinding wheel surface contacts with the cutter, and on the contrary, when the grinding wheel grinds the cutter, the grinding speed is a little slower when the grinding wheel line contacts with the cutter; the speed is the maximum speed when the walking is idle. Meanwhile, the speed of each step can be set and modified by a user, so that the grinding efficiency is improved.
The motion module is used for setting the speed when the path of the sharpening tool is planned. The module enables the motor to move to execute the planned action according to the planned cutter path. And meanwhile, displaying detailed information in the processing process of each step in the movement process, such as the processing position, the processing times, the processing time and the like.
Since the steps of sharpening the cutter are separated and then combined step by step, the efficiency is very low since the steps are performed step by step. In order to improve the efficiency, under the condition of no collision, the system adds a path optimization idea, carries out some steps at the same time, and greatly improves the grinding efficiency.
In this embodiment, an output and input device is further disposed on the knife sharpener, and the output and input device includes a keyboard and a display screen 3, which are connected to the control module, and the display screen is a touch display screen.
In this embodiment, the knife sharpener is further provided with a three-color lamp 4, and the working state of the knife sharpener is displayed through color conversion of the three-color lamp 4.
