Problems solved by technology

[0003] However, due to the delay characteristics of mechanical movement, when the processing starts, after the control system outputs a high level, the machinery and its transmission parts will have a period of delay from receiving the start signal to starting to move (τ 1 ), during this delay period, the laser emitting device is always in working condition, and the laser will always act on the starting point of the processing component, causing a large amount of heat to accumulate at the starting point of component processing, resulting in over-processing phenomenon, which affects the processing accuracy of the component certain impact, and even damage the processing components; when the machine and its transmission parts move to the end of processing, the control system will output a low-level signal to stop the laser emitting device and end the movement of the machine and its transmission parts, but from There will also be a time delay between the movement of the machine and its transmission parts to the end of processing and the stop of the laser emitting device
During this period of time, the laser emitting device is still in working condition, and the machinery and its transmission parts are still in motion, which also causes over-processing

specific Embodiment 1

[0024] A switching light editable laser processing system of the present invention includes a laser emitting device, processing equipment, a monitoring module, and a control center, and the processing equipment is used to process components with laser light according to the start processing signal and the end processing signal of the control center ;Laser emitting device and processing equipment can be moved and fixedly installed. The monitoring module is used to monitor the processing equipment delay time and laser delay time, and transmit the delay time to the control center. The control center controls the laser emitting device to emit laser light or stop emitting light according to the delay time The time point to ensure that the processing time of the laser at each processing point of the component is the same.

[0025] The processing equipment delay time includes the start-up delay time, and the start-up delay time is used to record the time interval from the time when th...

specific Embodiment 2

[0037] A switching light editable laser processing system of the present invention includes a laser emitting device, processing equipment, a monitoring module, and a control center.

[0038] Before the processing equipment starts processing, the control center sends the start processing signal and the laser emission signal at the same time, and the monitoring module measures the duration of the laser emitted by the laser emission device at the start processing point, which is the opening duration delay time; after the processing is completed, the control center simultaneously Send the stop processing signal and the end laser emission signal, and measure the duration of the laser after the final processing point as the termination duration delay time.

[0039] Specifically, such as figure 2 As shown, the control signal sent by the control center is shown in the A signal line in the figure, the operation sequence of the processing equipment is shown in the B signal line in the ...

specific Embodiment 3

[0049] A switch light editable laser processing method of the present invention, such as figure 1 As shown, measure or calculate the start-up delay time τ1 of the laser at the starting point of the processing equipment, and the delay time τ3 of laser emission. After the start processing signal is sent, delay a start-up delay time (τ1-τ3), and control The laser is emitted, so that at time t2, the synchronization between the start of the processing equipment and the laser irradiation is realized.

[0050] Measure or calculate the termination delay time τ4 of the laser after the final processing point, and stop the delay time τ4 in advance before the t3 time before the stop processing signal is sent, that is, stop the laser emission at the t6 time, so that at the t3 time when the processing is stopped, Realize the end of laser irradiation.

[0051] The delay times in this application are all described as positive delay times, and similarly, this application is also applicable to...

Abstract

The invention discloses a switching light editable laser processing system and method. The system includes a laser emitting device, processing equipment, a monitoring module, and a control center. The processing equipment is used to adopt laser processing components, and the monitoring is used to measure the processing equipment Delay time, laser delay time, the control center controls the time point when the laser emitting device emits laser light or stops emitting light according to the delay time. This application calculates or measures the mechanical delay time of the processing equipment, according to the delay time, appropriately sets the light-emitting time and the end time of the laser equipment, reduces the duration of the laser after the starting point and the ending point, and ensures that no excessive Processing phenomenon, improve processing accuracy, reduce loss.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a switching light editable laser processing system and method. Background technique [0002] At present, as an advanced manufacturing technology, laser processing has been widely used in the processing fields of automobiles, electronics, electrical appliances, aviation, metallurgy, machinery manufacturing, etc., and it plays an increasingly important role in improving product quality, labor productivity, automation, pollution-free, and reducing material consumption. role.
