Description of the Invention: [Technical Field] The present invention relates to a touch panel rotary encoding device, and more particularly to an application for reading motor rotation data, which can be obtained by a simple digital signal = And the absolute angle, so that it is not affected by the magnetic interference, and does not need precise optical scale and photoelectric reading device, and can save its cost, and it has more practical value in its overall implementation. Innovative designer of the touch panel rotary coding device. [Prior Art] Press, the motor is one of the most commonly used motion drivers 'widely used in various industrial products'. When the device using the motor needs to be controlled, it is necessary to obtain the current state data of the motor, and the most basic one is the motor. Speed and position. In digital motor control systems, in order to obtain dynamic information such as motor position, speed, torque, or other motor systems, the motor's digital control system must use a feedback sensor' to utilize the feedback signal. Various dynamic data of the motor are measured, and the feedback sensor includes a Hall sensor in a magnetic form, a potentiometer in the form of an impedance, and a tachometer in an electromagnetic induction form. ], synchometer, resolver, and the most commonly used suspect encoder. The 'rotary encoder' is a wheel or turntable with many slits fixed on the motor shaft. When the motor rotates, the optical sensor on the device will infer the number of slits passing through and generate electrical signals. The controller uses this electrical signal to calculate and control the rotational speed of the motor; while the sensor used in the rotary encoder can be divided into mechanical contact type and non-contact type, and the contact type 200909785 sensor is relatively inexpensive, but Short service life, suitable for low-speed applications. In non-contact sensors, the magnetic form is less sophisticated and easy to detect other magnetic interference, so most of them use photoelectric method, and the rotary encoder The photoelectric mode of the non-contact sensor is divided into two types: incremental and absolute. The incremental optical encoder (5), please refer to the schematic diagram of the prior art incremental optical encoder shown in the fourth figure, which is mainly provided with a rotary disk (52) on the rotating shaft (51). (52) Stripes having a circle of equal divisions (521) 'The strips (521) corresponding to the revolving discs (52) are respectively provided with photodetectors (53) and grating fixing discs (54) on the gratings. The fixed plate (54) is provided with a plurality of gratings (541) ' at the same time, each of the gratings (541) is respectively provided with a light-emitting diode (55) 'to enable the light emitted by the light-emitting diode (55) to pass through the grating The grating (541) on the fixed disk (54) and the stripe (521) on the rotating disk (52) are sensed by the photo-sensing device (53), and a set of continuous pulse waves is output by the photo-inductor (53); However, the incremental optical encoder (5) can be converted into the angular displacement of the motor due to the progressive counting, and the angle of the current system cannot be known at the beginning of the power supply of the motor system, which results in some restrictions on its use. . In addition, the absolute value optical encoder (6), please refer to the schematic diagram of the existing absolute value optical encoder shown in the fifth figure, which is mainly provided with a rotary disk (62) on the rotating shaft (61). An angle-encoded engraving (6 21) is printed on the revolving disk (62) in an absolute position. Each angle has a unique code, and the two sides of the angle-encoded engraving (621) corresponding to the revolving disk (62) are respectively provided. There is a photodetector (63) and a grating fixing plate (64), and a plurality of gratings (641) are arranged on the grating fixing plate (64), and corresponding gratings (641) are respectively provided with light emitting diodes (6 5 'Let's let the light emitted by the light-emitting diode (6 5 ) pass through the grating (641) on the 200909785 grating fixed disk (64) and the angle on the rotating disk (62). The sensing side of the photo-sensing device (63) is outputted via the photo-electrical sensor (63); however, the absolute-value optical encoder (6) is used in practice because the precision of the angular position depends on the number of bits of the encoding. , a higher number of bits can get a more precise angle value 'but must also increase the number of photo-sensing devices Resulting in higher costs which settings to use. The reason is that the inventor has provided a touch panel rotary coding device in order to achieve a complete improvement of the existing structure, in view of the rich experience in design and development and actual production of the relevant industry for many years. The purpose of the person. According to the touch panel rotary coding device of the present invention, the touch panel is mainly used as a detector for rotating the position of the motor, and the device has a rotary table at one end of the motor shaft, and is disposed at the outer end of the rotary table. There is a sensing object, and at the same time, the sensing object is provided with a touch panel, so that the sensing object can be touched or capacitively sensed to allow the touch panel to detect the position of the contact point, and the touch panel can be touched out. The absolute position of the two axes of the X and γ planes, and then the absolute angle value can be obtained by a simple = angular function calculation; thereby, not only does it not affect the magnetic interference, and does not require precise optical scales. Compared with the photoelectric reading device, it can save its cost, and it is more practical and practical in its overall implementation. θ [Embodiment] For a more complete and clear disclosure of the technical content, the purpose of the invention and the effects achieved by the present invention, the following is a detailed description, and the drawings and figures are also referred to.
