It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
The utility model provides a photoelectric sensing detecting system based on hold-in range 31 motion, it is shown in figure 1 to detect the schematic diagram, and this photoelectric sensing detecting system includes light source device and border position detection device, wherein, includes detection light source 11 in the light source device, and detection light source 11 sets firmly in the below of waiting to detect the slab band, towards waiting to detect the slab band direction light-emitting; as shown in fig. 2, the edge position detecting apparatus includes: the synchronous belt 31 is arranged above the plate belt to be detected and opposite to the detection light source 11; the photoelectric sensor 32 is fixed on the synchronous belt 31, and a sensor detection lens is arranged towards the direction of the plate belt to be detected; the motor driver 34 is connected with the signal processing chip and drives the motor 35 to move according to the control signal generated by the signal processing chip so as to drive the synchronous belt 31 to move; the motor 35 is in transmission connection with the synchronous belt 31; a displacement sensor (not shown in the figure) for detecting a displacement signal at the end of the motor 35 is disposed at the end of the motor 35 (the end of the motor specifically refers to the motor shaft, and the motor rotates to drive the encoder at the end of the motor to rotate during the operation process), and is connected to the photoelectric sensor. The photoelectric sensor 32 further includes: a signal processing chip 322 for processing the detection signal of the photoelectric sensor 32 to generate a control signal, wherein the signal processing chip 322 is respectively connected with the sensor detection lens 321 and the displacement sensor; and a communication module 323 for implementing communication with an external device, connected to the signal processing chip 322.
In this embodiment, in the detection process, the strip 20 to be detected continuously runs on the guide roll, and a photoelectric sensing detection system composed of a light source device and an edge position detection device and based on the movement of the synchronous belt 31 is configured to detect the edge of the strip in running. Specifically, the light source device is configured to provide a light source for the photoelectric sensor 32 in the edge position detection device, and the detection light source 11 is fixedly arranged below the to-be-detected strip 20 (in order to avoid the guide roll blocking the light source, the detection light source 11 is arranged in an area between the guide rolls), and emits light toward the to-be-detected strip 20. The edge of the plate strip 20 to be detected is detected by the photoelectric sensor 32 in the edge position detection device in real time based on light emitted by the light source device, the motor is driven by the motor driver 34 to drive the synchronous belt 31, the photoelectric sensor 32 is moved from the current detection position to a preset position of the edge of the opposite plate strip (the preset position is judged in a preset range by detecting a signal voltage value and a preset target value through the photoelectric sensor 32, specifically, when a difference value between the detected voltage signal and the preset target value is in the preset range, the judgment is made to reach the preset position), and then the actual position of the edge of the plate strip 20 to be detected is determined, so that the detection purpose is realized. For the fixing mode of the light source device and the edge position detecting device, the corresponding bracket is selected according to the actual situation, and the fixing mode is not limited specifically here. The motor drives the synchronous belt to run through the gear. The edge position of the plate strip to be detected is detected, and the detection is realized in a mode that a synchronous belt drives a photoelectric sensor to move, wherein the synchronous belt is arranged along the longitudinal direction of the plate strip to be detected (the running direction of the plate strip to be detected is assumed to be the transverse direction). The plate strip 20 to be detected can be a non-ferrous metal plate strip or other non-metal non-transparent plate strips.
In the detection process, the photoelectric sensor detects a high-frequency optical signal emitted by the detection light source 11 through the sensor detection lens 321, transmits the signal to the signal processing chip 322 after amplification, obtains a detection signal of the current sensor detection lens 321 after the high-speed digital signal processing chip 322 performs signal calculation, and generates a control signal according to a preset target value of the edge of the plate strip 20 to be detected and sends the control signal to the motor driver 34; the motor driver 34 drives the motor to move, so as to drive the synchronous belt 31 to run, and the photoelectric sensor is rapidly transmitted to a preset position at the edge of the opposite plate belt. In the process, the change of the edge position of the plate strip is tracked in real time, the movement distance of the motor can be obtained by sampling a signal of a displacement sensor at the tail end of the motor, and the movement distance is sent to a signal processing chip for processing, so that the actual position of the edge of the plate strip 20 to be detected is obtained; finally, the position signal is sent to an external device, such as a deviation correction controller of a production line, through the digital communication module 323. The detection principle of the actual position of the edge of the plate strip to be detected is as follows: assuming that the initial detection position of the photoelectric sensor 32 is a position corresponding to the edge of the strip 20 to be detected without deviation, after the photoelectric sensor 32 is driven to the preset position by the motor, the moving sensor detects the movement distance of the motor, and the movement distance of the photoelectric sensor 32 can be obtained (determined based on the correlation relationship between the motor movement distance and the movement distance of the photoelectric sensor 32 which are measured in advance), so as to determine the actual position of the edge of the strip 20 to be detected currently.
In an example, the detection voltage range of the photoelectric sensor is 0-10V, and the preset position is set to be the position of the edge of the corresponding plate strip when the detected voltage is 5V (the plate strip 20 to be detected shields half of the light of the sensor detection lens 321), if the preset position is less than 5V, the position of the plate strip 20 to be detected is deviated, and the light larger than half of the sensor detection lens 321 is shielded; when the voltage is more than 5V, the position of the plate strip 20 to be detected deviates, and light smaller than half of the detection lens 321 of the sensor is shielded. When the initial position is detected in one detection, the detection result is a 3V voltage signal, which indicates that the position of the plate strip 20 to be detected has a deviation and blocks light larger than half of the detection lens 321 of the sensor, the signal processing chip 322 generates a control signal according to the preset target value of 5V and sends the control signal to the motor driver 34, the motor is driven by the motor driver 34 to move to drive the synchronous belt 31 to operate, and the photoelectric sensor is quickly transmitted to the preset position (the position corresponding to the detected 5V voltage value) of the edge of the opposite plate strip. In the process, the movement distance of the motor is obtained by sampling the signal of the displacement sensor at the tail end of the motor, and the position of the edge of the plate strip 20 to be detected can be obtained.
In order to ensure that the photoelectric sensor can measure a stable and linear strip position signal, the stability of the detection light source 11 needs to be ensured, and thus, as shown in fig. 3, the light source device includes, in addition to the detection light source 11: a light intensity detection chip 12 for detecting the light intensity of the detection light source 11; a CPU 13 for processing the light intensity signal detected by the light intensity detecting chip 12 to generate a light source control signal, the CPU 13 being connected to the light intensity detecting chip 12; and an LED driving chip 14 for driving the light emission of the detection light source 11 according to the light source control signal generated by the CPU 13, wherein the LED driving chip 14 is respectively connected with the CPU 13 and the detection light source 11.
In the working process, the light intensity detection chip 12 detects the light intensity of the light source 11 according to a certain frequency, the CPU 13 compares the received light intensity signal with a preset light intensity, and if the difference between the received light intensity and the preset light intensity exceeds a preset range, a light source control signal is generated and sent to the LED driving chip 14, so that the LED driving chip 14 drives the light source 11 to emit light in a PWM manner, thereby obtaining the stable light source 11. In practical application, the detection light source 11 is a lamp strip including a plurality of LED chips, the length of the lamp strip and the light emitting area are determined by the area of the strip to be detected 20 and the detection area of the photoelectric sensor, and at least cover a position area to be detected in the strip to be detected 2020, for example, the size of the lamp strip is set to be 1 meter long and 20-30 mm wide. In addition, the distance between the detection light source and the detection lens of the sensor and the plate belt to be detected is not particularly limited, and can be adjusted and set according to actual detection requirements. In one example, the distance between the detection light source and the plate strip to be detected is larger than 10cm, and the distance between the detection lens of the sensor and the plate strip to be detected is set to be 80 cm-1.5 m.
In this embodiment, the photoelectric sensor 32 is disposed above the to-be-detected strip 20 and within the range covered by the emergent light of the detection light source 11, and the detection area covers the side edge position of the to-be-detected strip 20, so as to implement real-time detection on the edge position of the to-be-detected strip 20, and besides the detection result can help to judge whether the to-be-detected strip 20 deviates from the position, in the subsequent winding operation, the detection result can also send real-time position information to the controller of the winding machine through the communication module 323, so as to help the winding machine to implement the opposite-side winding operation.
The embodiment is obtained by improving the above embodiment, in this embodiment, two photoelectric sensors, two synchronous belts, two motor drivers and two motors are configured in the photoelectric sensing detection system, the two synchronous belts, the two motor drivers and the two motors are correspondingly arranged with one of the two photoelectric sensors, the two photoelectric sensors are all arranged above the plate strip to be detected and in the range covered by the emergent light of the detection light source, and the detection areas of the two photoelectric sensors respectively and correspondingly cover the edge position of one side of the plate strip to be detected.
In this embodiment, two photoelectric sensors are configured, and the positions of the two side edges of the strip to be detected can be detected simultaneously, so that the detection of the middle position of the strip to be detected is realized, and the centering and winding work in the subsequent application is realized. In addition, the plate strip deviation correcting device can be applied to a centering deviation correcting system of a production line, so that the plate strip which deviates from the center position of the production line is corrected to be at a zero position by the deviation correcting system. Moreover, by detecting the edge positions of two side edges of the plate strip to be detected, the width measurement of the non-ferrous metal plate strip and non-metal non-transparent industrial materials can be realized (the detection of the edge positions of one side plate strip is realized by two photoelectric sensors respectively).
It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for persons of ordinary skill in the art, a plurality of improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
