Description

Technical Field

[0001] This invention relates to the field of laser cutting and processing, and more particularly to the field of perforation methods. Specifically, it relates to a control method, device, processor, and computer-readable storage medium for improving perforation efficiency in laser processing. Background Technology

[0002] In existing laser processing piercing methods, the conventional approach is to set parameters such as piercing height, power, duty cycle, frequency, and focus before piercing. During piercing, the focus is adjusted and the device is moved to the piercing height. After piercing, the cutting parameters (power, duty cycle, frequency, etc.) are set, and the focus is readjusted and the device is moved to the cutting height before cutting begins.

[0003] This relatively precise perforation method works well for thick plates; however, it is somewhat inefficient for thin plates because they are easier to penetrate. The actual perforation process for thin plates can be further optimized.

[0004] Reference (1) invented a laser perforation method, a multi-stage perforation method, and a continuous perforation method. The next step is executed based on the measurement range of the obtained capacitance sensor, the current height of the laser head, and the target height. By increasing the tolerance value, the perforation action can be performed directly without adjusting the position of the laser head, provided that the difference between the current height and the target height is less than the tolerance, thus effectively improving the perforation efficiency.

[0005] Compared to this method, the other method focuses on improving the perforation efficiency of thick and extremely thick plates. Its solution also relies on comparing data from the capacitive sensor and set parameters to make different actions to optimize the perforation efficiency. In contrast, this method focuses on optimizing the perforation of plates that can be perforated in one step, thereby improving the perforation efficiency of thin plates.

[0006] Reference (2) invented a laser perforation method, which uses the frequency, duty cycle and focus to change during the perforation process, that is, the frequency is changed from high frequency to low frequency, the duty cycle is changed from high duty cycle to low duty cycle or from low duty cycle to high duty cycle, and the focus is changed from high defocus to low defocus, in order to solve the problems of hole bursting and overburning during the perforation process and achieve fast and stable perforation.

[0007] Compared to this method, the latter focuses on improving the quality of perforation by adding a parameter-changing process during perforation. In contrast, this method aims to improve the efficiency of perforating thin plates by optimizing and simplifying the perforation process and reducing the number and methods of issuing parameter-changing instructions, thereby achieving the goal of quickly and stably perforating thin plates.

[0008] The laser perforation methods disclosed in references (1) and (2) have different purposes and solutions than this method, and their focuses are also different. Combining them with the existing technology cannot achieve the goal of greatly improving the efficiency of perforation of thin plates. This method aims to improve the efficiency of perforation of thin plates from multiple dimensions, such as perforation method optimization, parameter distribution method optimization, and perforation process optimization.

[0045] (7) Proceed to the cutting process.

[0046] In a preferred embodiment of the present invention, step (1) further includes the following steps:

[0047] (1.1) Determine whether frog jump is enabled. If yes, set the follow height to the cutting height; otherwise, set the follow height to the perforation height.

[0048] In a preferred embodiment of the present invention, step (2) specifically includes the following steps:

[0049] (2.1) Set the blowing parameters to the parameters for cutting the blowing;

[0050] (2.2) Set the duty cycle of the piercing method to the preset duty cycle, and set the piercing power and piercing frequency to be the same as the cutting parameters;

[0051] (2.3) Set the perforation focus and the cutting focus to be the same.

[0052] In a preferred embodiment of the present invention, step (3) specifically includes the following steps:

[0053] (3.1) For operations that need to be performed synchronously, use addressing.

[0054] (3.2) Cache the addressing that needs to be checked repeatedly to local variables.

[0055] The apparatus of the present invention for controlling and improving the perforation efficiency in laser processing, wherein the apparatus comprises:

[0056] A processor is configured to execute computer-executable instructions;

[0057] The memory stores one or more computer-executable instructions, which, when executed by the processor, implement the steps of the control method, apparatus, processor, and computer-readable storage medium described above for improving perforation efficiency in laser processing.

[0058] The present invention discloses a processor for controlling improved perforation efficiency in laser processing, wherein the processor is configured to execute computer-executable instructions, which, when executed by the processor, implement the various steps of the aforementioned control method, apparatus, processor, and computer-readable storage medium for improving perforation efficiency in laser processing.

[0059] The computer-readable storage medium of the present invention stores a computer program thereon, which can be executed by a processor to implement the various steps of the control method, apparatus, processor and computer-readable storage medium thereof for improving perforation efficiency in laser processing described above.

[0060] In a specific embodiment of the present invention, a method for improving piercing efficiency is provided, which greatly reduces piercing time and improves piercing efficiency while ensuring piercing quality and consistency.

[0061] The present invention comprises the following steps:

[0062] S1: This perforation method is suitable for materials that can be perforated in one step, and for scenarios where perforation does not require changes to air pressure and focus.

[0063] S2.1: This perforation method will obtain the cutting height before perforation. If the frog jump is enabled, the follow height will be set to the cutting height. If the frog jump is not enabled, the follow height will be set to the perforation height.

[0064] S2.2: Set the blowing parameters to the parameters of the cutting blowing (including gas type and gas pressure);

[0065] S2.3: Set the duty cycle of this perforation method to the preset duty cycle, and set the perforation power and perforation frequency to be the same as the cutting parameters;

[0066] S2.4: Set the perforation focus and cutting focus to be the same.

[0067] S2.5: For operations that need to be performed synchronously (such as turning on the light or blowing air), use addressing to perform the operation, and use asynchronous addressing as much as possible;

[0068] S2.6: Cache addressing that needs to be checked repeatedly to local variables to save time;

[0069] S2.7: Use the greatest possible speed and acceleration to reduce frog jump planning time;

[0070] S2.8: Since the final stage of the frog jump is actually a follow-up action, the switch follow-up process is canceled when piercing after the frog jump to save time;

[0071] S2.9: Drill holes simultaneously during the time it takes for the device to descend to the cutting height.

[0072] S3.1: Avoid high-level following to prevent affecting speed;

[0073] S3.2: Due to the low time accuracy of the system, the light is turned on first and then the follower is turned on during the perforation process, sacrificing some efficiency to improve the perforation consistency.

[0074] S4: Utilize WaitPort time to perform multiple operations simultaneously.

[0075] In practical applications, the perforation process is as follows: Figure 1 As shown:

[0076] 1. After the frog jumps to the piercing point, the follow-up height will be set to be equal to the cutting height;

[0077] 2. Start blowing air and set the laser parameters (power, frequency, focus) to be the same as the cutting parameters;

[0078] 3. After the frog jumps into position, the consecration ceremony will begin and the perforation will commence;

[0079] 4. Continue drilling as the device descends to the cutting height;

[0080] 5. After waiting for the perforation to complete, turn on the follow-up mechanism and then proceed with the cutting process.
