For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] like Figures 1 to 4As shown, an angle-controlled and reset code disk includes a code disk body 10, wherein a through hole 13 is provided in the middle of the code disk body 10, and the through hole is circular. N (N≥2) groups of arc edges 1 and arc grooves are evenly arranged on the outside of the code disk body 10, wherein the arc edges 1 and arc grooves are evenly spaced, and the center angles of the arc edges and arc grooves are 360 / N, and the angle through which a group of arc edges and arc grooves rotate is the center angle. The radius of the arc edge 1 is R1, and the arc grooves include a first arc groove 11 and a second arc groove 12, wherein one second arc groove 12 is provided, and the rest are first arc grooves 11. The radius of the first arc groove 11 is R2, and the radius of the second arc groove 12 is R3, and R1, R2 and R3 are concentric circles, and R1 is greater than R2, and R2 is greater than R3. The arcuate groove is lower than the arcuate edge, and the outer peripheral edge of the code disk is evenly divided into N arcuate edges and N arcuate grooves, wherein the arcuate groove is lower than the arcuate edge and is concave. The arcuate groove includes a first arcuate groove and a second arcuate groove, wherein one second arcuate groove is provided, and the rest are first arcuate grooves, and the second arcuate groove is more concave than the first arcuate groove. The through hole 13, the arcuate edge 1 and the arcuate groove are at the same center of a circle, wherein the radius of the circle formed by the second arcuate groove, the first arcuate groove and the arcuate edge gradually increases. The arcuate edge is located at the outermost periphery, the first arcuate groove is located in the middle, and the second arcuate groove is located in the innermost layer. In this embodiment, the angle is controlled to be 45 degrees, and the corresponding N value is 8.
[0028] When the code disk rotates, the arc edge appears periodically. The center angle between the arc edge and the arc groove is the rotation angle, which is the control rotation angle. The second arc groove appears only once for each rotation of the code disk. Through the control corresponding to the installation relationship, the target object driven by the second arc groove is at the origin position when it appears, which is the control reset.
[0029] like Figures 2 to 4 As shown, the utility model also discloses a signal acquisition device for angle control and reset, including the aforementioned code disk, a first optical coupler 2, a second optical coupler 3 and a controller, wherein the first optical coupler 2 and the second optical coupler 3 are electrically connected to the controller, and the controller adopts a conventional single-chip microcomputer or a conventional PLC. The first optical coupler 2 includes a first optical coupler opening 21, and the second optical coupler 3 includes a second optical coupler opening 31. The code disk is installed below the first optical coupler opening 21 and the second optical coupler opening 31. When the code disk rotates, the first optical coupler 2 is periodically blocked by the arc edge 1, and the second optical coupler 3 is periodically blocked by the arc edge 1 and the first arc groove 11.
[0030] The code disk is installed below the first and second optocoupler openings, so that when the code disk rotates, it passes through the first and second optocoupler openings, and there is signal transmission between the optocouplers. When the code disk passes, the signal between the optocouplers is periodically blocked. When the code disk blocks the signal of the optocoupler opening, the signal transmission between the optocouplers is interrupted, and vice versa, the signal between the optocouplers is transmitted normally. By adjusting the installation position, when the code disk rotates, the first optocoupler is only blocked by the arc edge, and the second optocoupler is blocked by the arc edge and the first arc groove. Since the arc edge of the code disk is located in the outermost layer, the first arc groove is located in the middle, and the second arc groove is located in the innermost layer, the first arc groove and the second arc groove will not block the first optocoupler when passing through the first optocoupler, but will block the signal transmission on both sides of the second optocoupler opening. Only when the second arc groove passes through the second optocoupler opening will it not block the signal transmission between the two sides of the second optocoupler opening. When the signals on both sides of the first optocoupler opening and the second optocoupler opening are blocked, a high level is output, and when the signals on both sides of the first optocoupler opening and the second optocoupler opening can be transmitted, a low level is output. When the arc edge passes through the first optical coupler opening, the rotation of the code disk is collected. The rotation of the code disk corresponds to the rotation of the target object, and the second optical coupler is continuously blocked. Only when the second arc groove passes, the signals on both sides of the second optical coupler opening are transmitted normally. The second optical coupler collects the moment when the second arc groove passes. When the second arc groove passes, the target object driven to rotate is in a reset state (preferably directly above the surface of the target object in this embodiment).
[0031] The signal between the second optocouplers is at a low level during transmission. When the controller detects that the second optocoupler is at a low level, the motor is controlled to stop rotating, thereby achieving reset. When resetting, the second arc groove of the code disk is inside the second optocoupler, and the arc edge is at the opening edge of the first optocoupler. From the time the controller detects that the first optocoupler is at a high level after reset to the time it is at a high level next time, the motor stops rotating, that is, the controlled rotation angle is 45 degrees.
[0032] like Figures 1 to 5 As shown, the utility model also discloses a processing device for angle control and resetting, including the aforementioned signal acquisition device, and also including a rotating motor and a rotating shaft. Figure 5 Only the electrical connection relationship of the processing device is described without drawing the specific mechanical structure.
[0033] The specific structure of the processing device is:
[0034] The rotating shaft is installed in the through hole 13 of the code disk, the first optical coupler 2 and the second optical coupler 3 are connected to the controller, the controller is connected to the rotating motor, and the rotating motor is transmission-connected to the rotating shaft; the relative position relationship between the rotating shaft and the code disk is such that when the second arc-shaped groove 12 is located in the second optical coupler 3, the object driven on the rotating shaft is directly above.
[0035] When the signal between the first optocoupler 2 and the second optocoupler 3 is blocked, it is at a high level. When the signal between the first optocoupler 2 and the second optocoupler 3 is conducted, it is at a low level.
[0036] In actual use, a target object is installed on one side of the shaft, such as a clamping device for installing the detected equipment. When the processing device is started, it is driven to rotate by the rotating motor, and the rotating motor drives the code disk and the clamping device on the shaft to rotate. When the second arc groove of the code disk rotates into the opening of the second optocoupler, the second optocoupler outputs a low level, and the controller controls the motor to stop rotating, and the clamping device is reset. After resetting, the motor is controlled by the controller to rotate. From the first input of the high level to the next input of the high level by the first optocoupler, the rotation angle is a set of arc edges and arc grooves corresponding to the center angle of the circle. The start and stop of the motor are controlled by different level signals input by the first optocoupler. The angle corresponding to each rotation is the center angle of the arc edge and arc groove corresponding to the pre-divided arc edge and arc groove. The controlled rotation angle is a set of arc edge and arc groove corresponding to the center angle and its multiples.
[0037] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
