Description

Technical Field

[0001] The present application relates to the field of laser engraving, and in particular to a laser driving method, a laser, a computer storage medium and an electronic device. Background Art

[0002] At present, users have strong expectations for laser engraving machines to achieve stronger cutting capabilities. Low-power laser modules are only suitable for engraving scenarios but not for a wide range of cutting scenarios. They cannot meet user needs and are gradually being eliminated by the market.

[0003] In order to meet the user's demand for cutting capabilities, the current civilian laser engraving machines are designed with increasingly higher power LD light source modules. Since the power of a single semiconductor laser is limited, the incoherent spatial combination method is often used to accumulate the power of the LD light source to achieve the power required by the module. The laser modules currently on the market use a series design of LD light sources with the same power to achieve power superposition. Although the power meets the cutting requirements, due to its series drive design, the LD light source must work at the same time, and the light spot is the effect of the superposition of the light spots of several light sources. Therefore, its light spot is larger and affects the thickness of the engraving lines, which ultimately leads to poor engraving effects. Summary of the invention

[0038] To facilitate understanding, some illustrations of concepts related to the embodiments of the present application are given by way of example for reference.

[0039] Laser is a device that can emit laser light. According to the working medium, lasers can be divided into four categories: gas lasers, solid lasers, semiconductor lasers and dye lasers. The light source is LD (Laser Diode) light source. The physical structure of the laser diode is to place a layer of photoactive semiconductor between the junctions of the light-emitting diode. After polishing, the end face has a partial reflection function to form an optical resonant cavity.

[0040] Please refer to Figure 1 , is a flow chart of the working method of the laser provided in the embodiment of the present application. This embodiment is applied to the laser side, and the laser includes a plurality of light sources with different powers, such as Figure 1 As shown, the following steps are included:

[0041] Step S101: In response to the mode selection information, determine the operating mode of the laser.

[0042] In some embodiments, the working mode of the laser can be determined in the following manner: in response to key operation information of the user, the working mode corresponding to the key operation information is determined.

[0043] For ease of understanding, the following Figure 2 Explain how the user can switch the working mode of the laser through key operation:

[0044] like Figure 2 The figure shows the laser working mode switching diagram. The user selects the laser working mode through the button on the laser. The dedicated microcontroller equipped with the laser switches the laser working mode according to the user's button selection. Every time the microcontroller detects a 3-second long press of the button, it switches the current working mode of the laser; the switching order is 10W engraving mode -> 20W cutting mode -> 30W cutting mode; the LED mode indicator equipped with the laser indicates the current working mode.

[0045] It is understandable that how to switch the working mode of the laser is not limited to this. Multiple buttons can also be set, and different buttons correspond to different working modes. This embodiment does not specifically limit how to determine the working mode of the laser, and it can be set according to actual needs.

[0046] Step S102: determining the light output power corresponding to the working mode, and selecting a light source with the same light output power from a plurality of light sources with different powers as the working light source.

[0047] Step S103: driving the working light source to emit light.

[0048] In some embodiments, the working modes include: a low-power working mode, a high-power working mode and a maximum-power working mode; the determining of the light output power corresponding to the working mode includes: when the working mode is the low-power working mode, determining the light output power to be a first power; when the working mode is the high-power working mode, determining the light output power to be a second power; when the working mode is the maximum-power working mode, determining the light output power to be a third power, wherein the first power is less than the second power, and the third power is equal to the sum of the first power and the second power.

[0049] In some embodiments, a plurality of light sources of different powers include a first light source having the first power and a second light source having the second power; driving the working light source to emit light includes: when the working mode is the low-power working mode, driving the first light source to emit light; when the working mode is the high-power working mode, driving the second light source to emit light; when the working mode is the maximum-power working mode, driving the first light source and the second light source to emit light at the same time.

[0050] In some embodiments, the first power is 10 watts. At this power, the laser is suitable for picture engraving and printing scenarios. The laser selects the first light source from a plurality of light sources with different powers as the working light source to perform light emitting work, which can achieve the best engraving effect.

[0051] In some embodiments, the second power is 20 watts. At this power, the laser is suitable for fast cutting of thin plates and precision cutting of medium-thickness plates. The laser selects a second light source from a plurality of light sources of different powers as the working light source to perform light emitting work, thereby achieving the desired cutting effect.

[0052] In some embodiments, the third power is 30 watts. At this power, the laser is suitable for thick plate cutting scenarios. All light sources of the laser are working to emit light, and the desired cutting effect can be achieved.

[0053] It can be understood that the powers of the first light source and the second light source listed above are all feasible implementation methods. In actual applications, there is no limitation on the power of each light source and it can be set according to the actual needs of the working scene.

[0054] For ease of understanding, the following takes as an example a light source group in which the first light source is composed of two 5-watt laser diodes and a light source group in which the second light source is composed of four 5-watt laser diodes. Figure 3 For an explanation of the laser spot size in each operating mode: please refer to Figure 3 , is a schematic diagram of the working spot size of the laser in three working modes.

[0055] The first light source and the second light source are connected in parallel and can be driven independently. In the 10-watt engraving and cutting mode, since only the two laser diodes of the first light source emit light, the light spot is fine, the image engraving imaging effect is the best, the thin plate cutting slit is small, and the precision is high. In the 20-watt cutting mode, the four laser diodes of the second light source emit light, the light spot size is moderate, and the light output power meets the cutting of medium-thick materials and fast cutting of thin materials. The slit is moderate to ensure the precision of the finished cutting product; in the 30-watt cutting mode, the first light source and the second light source have a total of six laser diodes that emit light at the same time, and the laser outputs the maximum cutting power.

[0056] For ease of understanding, the following takes the example that the first light source includes light source a1 and light source a2; the second light source includes light source b1, light source b2, light source b3 and light source b4. Figure 4 The working mode of the laser machine in this embodiment is described in detail. Figure 4 , which is a schematic diagram of the spatial combination structure of the laser.

[0057] (1) The LD laser light source is screened and the beam shape is adjusted through a special lens group a1, a2, b1, b2, b3, and b4. Only the light of the specific wavelength required by the module can be reflected by the lens group into the vertical downward optical channel.

[0058] (2) After the laser passes through lens group c, it is focused onto the work material.

[0059] (3) Lens group d is a dustproof flat window to protect the lens, preventing dust from entering the light channel and contaminating the lens.

[0060] (4) The light source module (i.e., the first light source and the second light source) generates noticeable heat when in operation. To ensure sufficient heat dissipation capacity, the module light source bracket is designed to be made of metal material and is usually equipped with a heat dissipation fin structure and a heat dissipation fan to assist in heat dissipation.

[0061] (5) The maximum light output power of the laser is when light sources a1, a2, b1, b2, b3, and b4 are working simultaneously.

[0062] (6) a1, a2 and b1, b2, b3, b4 light sources can be driven to emit light individually.

[0063] (7) In the 10-watt engraving and cutting mode, the laser drives the 10-watt light source group composed of a1 and a2 to work. The light spot is small, which is suitable for fine line printing and engraving and thin plate cutting. The engraving effect is fine and the cutting seam is small.

[0064] (8) In the 20-watt cutting mode, the module drives the 20-watt light source group consisting of b1, b2, b3, and b4 to produce light. The light spot size is moderate, which is suitable for cutting medium-thickness plates with high cutting accuracy requirements and fast cutting of thin plates.

[0065] (9) In the 30-watt cutting mode, the a1, a2, b1, b2, b3, and b4 light sources are controlled to emit light simultaneously, outputting the maximum cutting capacity of the module.

[0066] Compared with the related art, the embodiments of the present application have at least the following advantages: the laser is formed by a combination of multiple light sources of different powers, and the working mode of the laser is determined to determine the light output power corresponding to the working mode, so that the laser machine can set different light output powers by switching different working modes, so that the laser can be suitable for different working scenes, such as engraving, cutting, etc., to achieve the best engraving and cutting effects in the working scene, thereby improving the practicality of the laser.

[0067] Please refer to Figure 5, which is a flow chart of a driving method of a laser provided in an embodiment of the present application. This embodiment is an explanation of the above-mentioned embodiment, and specifically explains how to drive different light sources to emit light. The laser also includes a first driving circuit and a second driving circuit. The first driving circuit drives the first light source to emit light when receiving a high-level light-emitting signal, and the second driving circuit drives the second light source to emit light when receiving a high-level light-emitting signal.

[0068] This embodiment is applied to the laser side, such as Figure 5 As shown, the following steps are included:

[0069] Step S201: In response to the mode selection information, determine the operating mode of the laser.

[0070] Step S202: When the working mode is the low-power working mode, a high-level optical output signal is sent to the first driving circuit and the second driving circuit, and the optical output signal sent to the second driving circuit is controlled to be converted from a high level to a low level.

[0071] In some embodiments, the high and low levels of the light output signal sent to the driving circuit can be controlled by controlling whether the transistor is turned on.

[0072] For ease of understanding, the following example uses a 10-watt light source group as the first light source and a 20-watt light source group as the second light source. Figure 6 How to implement the driving method in the low power working mode in this embodiment is described by example: Figure 6 As shown, it is a schematic diagram of the driving method of the laser in the low-power working mode.

[0073] (1) The laser engraving machine host sends a light-emitting instruction and a light-emitting signal to the laser module (i.e., the first light source and the second light source). The laser module will work only after receiving the light-emitting instruction, otherwise it will not work.

[0074] (2) The output light signal is a pulse width modulation (PWM) signal, and the duty cycle of the PWM signal is proportional to the output light power currently required by the laser.

[0075] (3) The transistor is of NPN type. After the module microcontroller raises its base voltage, the transistor is turned on, pulling down the optical output signal of the line.

[0076] (4) The constant current driving circuits a and b will only drive the corresponding light source group to emit light when they receive a high-level light-emitting signal.

[0077] (5) In the 10-watt engraving mode, the module microcontroller raises the base voltage of transistor b, transistor b is turned on, signal b is converted from high level to low level, and the 20-watt light source group does not work; the base of transistor a is pulled down and does not conduct, signal a is normally input into the constant current drive circuit a, driving the 10-watt light source group to emit light and work.

[0078] In some embodiments, it is not limited to triodes, and other structures can be used to control the high-low level conversion of the light output signal sent to the driving circuit, such as a switch, etc. This embodiment does not specifically limit the structure for controlling the high-low level conversion of the light output signal sent to the driving circuit.

[0079] Step S203: when the working mode is the high-power working mode, a high-level optical output signal is sent to the first driving circuit and the second driving circuit; and the optical output signal sent to the first driving circuit is controlled to be converted from a high level to a low level.

[0080] For ease of understanding, the following example uses a 10-watt light source group as the first light source and a 20-watt light source group as the second light source. Figure 7 How to implement the driving method in the high power working mode in this embodiment is described by example: Figure 7 As shown, it is a schematic diagram of the driving method of the laser in the high-power working mode.

[0081] In the 20-watt cutting mode, the module microcontroller raises the base voltage of transistor a, transistor a is turned on, signal a is converted from high level to low level, and the 10-watt light source group does not work; the base of transistor b is pulled down and not turned on, and signal b is normally input into the constant current drive circuit b, driving the 20-watt light source group to emit light and work.

[0082] Step S204: When the working mode is the maximum power working mode, a high-level light output signal is sent to the first driving circuit and the second driving circuit.

[0083] For ease of understanding, the following example uses a 10-watt light source group as the first light source and a 20-watt light source group as the second light source. Figure 8 How to implement the driving method in the maximum power working mode in this embodiment is described by example: Figure 8 As shown, it is a schematic diagram of the driving method of the laser in the maximum power working mode.

[0084] In 30W cutting mode, the module microcontroller pulls down the base voltage of transistors a and b, transistors a and b are not conducting, and signals a and b are normally input into constant current drive circuits a and b, driving the 10W light source group and the 20W light source group to work simultaneously.

[0085] Compared with the related art, the embodiments of the present application have at least the following advantages: the laser is formed by a combination of multiple light sources of different powers, and the working mode of the laser is determined to determine the light output power corresponding to the working mode, so that the laser machine can set different light output powers by switching different working modes, so that the laser can be suitable for different working scenes, such as engraving, cutting, etc., to achieve the best engraving and cutting effects in the working scene, thereby improving the practicality of the laser.
