Description
一種訊號傳輸裝置，尤指使用於多軸運動系統，以串列壓縮訊號，用以傳輸訊號至接收及顯示裝置之訊號傳輸裝置。 A signal transmission device, especially for a multi-axis motion system, for serially compressing signals for transmitting signals to a signal transmission device of a receiving and display device.
按，一般多軸運動系統需要利用傳動方式移行作動機件或物件，以進一步對工件進行處理。然而，多軸運動系統因受磨擦力或機械力之影響，而無法控制作動機件或物件精準地傳動至預定位置，如此多軸運動系統即會產生加工不準確等問題。因此，為克服多軸運動系統無法精確運動至預定位置進行加工而導致加工不準確的問題，習知解決方式為利用量測位置之線性光學尺或旋轉編碼器等量測器而取得各軸向之移行尺寸，以進一步補正傳動上之誤差值，因此習知多軸運動系統常將量測器設置於傳動軸向，然而，多軸運動系統的傳動軸運轉常造成大量雜訊，使量測器量測位置之訊號受干擾而無法精準傳輸至接收及顯示裝置上，並需要利用多條配線來傳輸訊號，造成多軸運動系統之空間浪費。 Press, the general multi-axis motion system needs to use the transmission method to move the moving parts or objects to further process the workpiece. However, the multi-axis motion system cannot be controlled by the friction force or the mechanical force to control the actuator or the object to be accurately driven to a predetermined position, and thus the multi-axis motion system may cause problems such as inaccurate machining. Therefore, in order to overcome the problem that the multi-axis motion system cannot be accurately moved to a predetermined position for processing, the processing is inaccurate, and the conventional solution is to obtain each axial direction by using a linear optical scale or a rotary encoder such as a measuring position. The moving dimension is used to further correct the error value on the transmission. Therefore, the conventional multi-axis motion system often sets the measuring device in the transmission axial direction. However, the transmission shaft of the multi-axis motion system often causes a large amount of noise, so that the measuring device The signal at the measurement position is disturbed and cannot be accurately transmitted to the receiving and display device, and multiple wires are needed to transmit signals, resulting in wasted space for the multi-axis motion system.
