The one-line wave mirror light beam shaping method specifically operates as follows:

[0062] Determine the incident angle of the one-line wave mirror;

[0063] According to the required range and the spot line length, the incident angle of the one-line wave mirror is calculated, assuming that the range is Y meters, the required spot line length is X meters, and the incident angle is A degrees, then:

[0064]

[0065] The required angle A is calculated through the mathematical relationship;

[0071] It should be further noted that the optical signals are converted into electrical signals and transmitted to the single-chip microcomputer after the laser receiver receives the planar area optical signals, and this process is to collect laser positioning information; specifically, the laser positioning information includes the blocked beam information of the receiver: whether it is blocked, and the blocked part.

[0072] S3: Collect laser positioning information, limit and set the motor speed through the laser positioning information, control the motor segmented motion in combination with the segmented distance, and obtain the motor parameters;

[0079] Furthermore, by limiting and setting the motor speed through laser positioning information, combining with the segmented distance control of the motor segmented motion, it also includes,

[0080] When descending within the first section of the downlink distance H1, if the receiving area of the receiver is blocked, the bending speed is directly reduced to 0 cm / s, and the detection continues until there is no shielding, and the bending speed continues to descend at the original speed;

[0081] Keep checking the downlink distance, if the downlink distance is less than the first section of the downlink distance H1, continue to descend, if the downlink distance reaches the first section of the downlink distance H1, reach the speed change point, at this time the bending speed is directly reduced to 1 cm / s.

[0082] Furthermore, if the downlink distance does not reach the second section of the downlink distance H2, the receiver's receiving area is blocked, the speed continues to be 0 cm / s, and the detection continues until no shielding is detected, and the downlink continues, if the distance reaches the second section of the downlink distance H2, then the shielding point is reached, at this time the receiver shielding function is turned on, and the downlink distance is continuously checked.

[0083] Furthermore, when the downlink distance reaches the first target point, the bending tool tip O and the bending bottom are closed to complete a bending process, the motor starts to reverse at the original speed V, and the bending tool tip O goes up;

[0084] The first target point is H3-D;

[0085] Check the uplink distance, if the uplink distance reaches the shielding point, turn off the shielding function, continue to go up, at this time if the receiving area detects that the light beam is blocked, the speed is reduced to 0 cm / s, if there is no shielding, continue to go up at the original speed V, until the uplink distance reaches H3-D, then the motor stops, the bending tool tip O returns to the initial position, and the next bending is continued, and the cycle is repeated;

[0101] Embodiment 2

[0102] Reference Figures 1-7 For an embodiment of the present application, an application scenario of a laser-triggered bending machine device control method is provided, and the feasibility and effect of the present application are described.

[0103] S1: After installing the device, the light beam is shaped to obtain a planar area;

[0104] The installation device includes a laser emitter, a laser receiver, a power supply, an electric governor, a communication module, a controller module, and a support. The laser emitter and the laser receiver are installed in parallel at a height on both sides of the bending machine through the support.

[0105] The specific schematic is shown in Figure 2 The laser emitter 4 and the laser receiver 5 are fixedly installed in parallel on both sides of the bending machine through the support 2 and stably move up and down with the bending blade tip; the external motor 1 is used to control the up and down movement of the bending blade tip 3; the controller module 8 adopts a single-chip microcomputer, which is used to power the laser receiver, receive and process the laser positioning information transmitted by the laser receiver 5, receive the motor running state information feedback by the electric governor 7, and adjust the motor running speed according to the laser positioning information. The power supply 6 is used to power the laser emitter 4, the controller module 8, the electric governor 7, and the communication module 9; the communication module 9 is used to realize wireless transmission between the electric governor 7 and the single-chip microcomputer and between the single-chip microcomputer and the external terminal.

[0106] The specific connection isFigure 3 As shown, the power supply is electrically connected to the controller module, laser transmitter, ESC, and communication module. The controller module's built-in 5V output port is electrically connected to the laser receiver module and its I / O port. The ESC is electrically connected to the external motor's CAN data line. The controller module is connected to the communication module, and the communication module is connected to the ESC via the CAN data line.

[0107] The laser beam is emitted by the laser emitter and then irradiated onto the receiving area of ​​the laser receiver using a line-shaped wavy mirror beam shaping method. At this time, the laser beam forms a planar area.

[0108] S2: Divide the planar region into three dividing planes;

[0109] Dividing a planar region as follows Figure 4 As shown, the planar region formed by the laser beam is defined as the front, middle, and rear of the laser beam, centered on the tip of the bending blade, according to a certain proportion.

[0110] S3: Collect laser positioning information, limit and set the motor speed using the laser positioning information, control the motor's segmented movement by combining the segmented distance, and obtain the motor parameters;

[0111] The photoelectric signal conversion and acquisition process involves receiving laser light signals from each part (front, middle, and rear) of the planar area via a laser receiver, converting the light signals into electrical signals, and transmitting them to the microcontroller. This process is called laser positioning information acquisition.

[0112] The laser positioning information is processed by a microcontroller, and the motor speed is set and limited based on the positioning information to control the motor movement.

[0113] The motor movement is controlled based on laser positioning information and segmented distances, as illustrated in the following diagram. Figure 6 As shown, the flowchart is as follows Figure 7 As shown, the specific implementation is as follows:

[0114] Initialize the parameters, set the initial speed of the motor to the original bending speed V, set the thickness of the material to D, set the downward distance of the bending tip O to H1 as the speed change point, set the downward distance of the bending tip O to H2 as the shielding point for laser reception, and set the distance from the initial bending position to the bottom bending position to H3, where H3>H2>H1, and V<the maximum speed of the motor;

[0115] Set and limit motor speed based on the distance and position of the bending blade tip and laser positioning information:

[0116] When the receiver's receiving area is blocked within the first downlink distance H1, the bending speed is directly reduced to 0 cm / s, and then the detection continues until no blockage is detected, the bending speed continues to downlink at the original speed, and the downlink distance is kept checking. If the downlink distance is less than H1, the downlink continues. If the downlink distance reaches H1, the speed change point is reached. At this time, the bending speed is directly reduced to 1 cm / s, and the downlink distance is kept checking. If the downlink distance does not reach H2: when the receiver's receiving area is blocked, the speed continues to be 0 cm / s, and then the detection continues until no blockage is detected, and the downlink continues. The downlink distance is kept checking. If the distance reaches H2, it means that the shielding point is reached at this time. At this time, the shielding function of the receiver is turned on. The downlink distance is kept checking. If the downlink distance reaches H3-D, it means that the bending knife tip and the bending bottom are closed. At this time, one bending process is completed. The motor starts to reverse at the original speed V. The bending knife tip goes up. The uplink distance is checked. If the uplink distance reaches the shielding point (H3-D-H2), the shielding function is turned off, and the uplink continues. At this time, if the receiving area detects that the light beam is blocked, the speed is reduced to 0 cm / s. If there is no blockage, the uplink continues at the original speed V. When the uplink distance reaches H3-D, the motor stops, indicating that the bending knife tip O returns to the initial position. Then the next bending is performed, and the cycle is repeated.

[0117] It should be noted that the positions of the components shown in Figure 2 Fig. 1, such as the motor 1, the support 2, the bending knife tip 3, the laser emitter 4, and the laser receiver 5, are fixed. Among them, the components 4 and 5 must be located on the same horizontal line and be parallel. The component 3 is located in the vertical direction of the midpoint of the horizontal line of the components 4 and 5. The positions of the remaining components are not limited to their actual positions, which can be adjusted according to actual needs.

[0118] S4: receiving motor parameters and motor running state information, and controlling motor movement according to the motor parameters and motor running state information to achieve speed closed-loop control.

[0119] The motor running state information is fed back through the electric adjustment CAN communication. The motor movement is controlled. The error between the current speed and the set speed is compensated by using the PID algorithm to adjust the speed of the motor, so as to achieve speed closed-loop control.

[0120] Finally, data transmission is performed. The current laser positioning information and motor running parameter information are transmitted to the external terminal in real time through the wireless WIFI module in the communication module, so as to realize the monitoring of the motor information of the bending machine equipment.
