However, this method can only limit the speed and acceleration of the initial point and the end point, and does not limit the speed and acceleration in the process. There may be a large speed and acceleration in the process, which may cause damage to the machine; 4) the existing electronic cam curve The generation method algorithm requires a lot of parameters for each point, such as the point position, speed, acceleration and deceleration interval time, and acceleration interval time, which is not convenient to use

Embodiment Construction
[0035] Such as figure 1 As shown in the system of the electronic cam control device, the electronic cam control device 201 receives the active shaft position feedback 105 and the electronic cam curve setting information 106, and after generating the electronic cam curve, sends a position command 107 to the driven shaft drive unit 102 The servo motor driver 103, the servo motor driver 103 converts the position command 107 into a current 108 and outputs it to the servo motor 104, and the servo motor 104 transmits the position feedback 109 to the servo motor driver 103 for action, so as to achieve the electronic cam control device 201 generated The trajectory of the electronic cam curve.
[0036] Such as figure 2As shown, the electronic cam control device 201 includes an information reading unit 202, which reads the specific point position and related parameters set by the user from the electronic cam curve setting file 210; an electronic cam curve generation unit 203, accordin...

The invention discloses an electronic cam control device and an electronic cam curve generation method thereof. The device comprises an information reading unit used for reading and analyzing a driven shaft position setting file; an electronic cam curve generation unit used for generating an electronic cam curve according to limiting conditions set by a user; an electronic cam curve memory unit used for storing the generated electronic cam curve; a position command generation unit used for referring to position feedback of a driving shaft and converting a stroke plan of the electronic cam curve into a position command; and a command output unit used for outputting the position command to a driven shaft driving unit which acts according to the received position command. In a stoke planning process, a solver meeting conditions is selected according to the limiting conditions and a solving result of the last time until a solution meeting the limiting conditions is found; and in the solving process, the speed, acceleration, accelerated acceleration and the like in the process are considered, and a machine bench protection function is achieved.
Description
technical field [0001] The invention relates to an electronic cam control device and an electronic cam curve generation method, in particular to an electronic cam control device and an electronic cam curve generation method for generating an electronic cam curve for stroke planning. Background technique [0002] The electronic cam control device can set an electronic cam curve, and then control the servo motor through the servo system, so that the position of the driven shaft corresponds to the position of the driving shaft to meet the corresponding relationship set by the electronic cam curve. Electronic cam curves are more flexible and convenient to use, and have been gradually used to replace traditional mechanical cams. Cams are often used in the automation industry. Electronic cam curves are more flexible than mechanical cams. It is not necessary to change the cam when the curve needs to be modified. It can be used by setting a new electronic cam curve through software....
