Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a laser embroidery device provided in the present application.

The laser embroidery device 10 includes a controller 110, a communication bus 120, and a laser device 130, and the laser device 130 includes a laser embroidery head 131. The controller 110 is in communication connection with the plurality of laser devices 130 through the communication bus 120 for sending control signals to the laser devices 130; the laser device 130 can control the laser embroidery head 131 to embroider according to the control signal.

In this embodiment, the controller 110 is a main control device of the laser embroidery device 10. Which can control the operation of the laser embroidering apparatus 10. It is understood that the laser device 130 includes a plurality.

The plurality of laser devices 130 in the laser embroidery device 10 can be directly connected to the controller 110 through the communication bus 120, so that the controller 110 can directly send a control signal to each laser device 130, thereby independently controlling each laser device 130. Furthermore, the plurality of laser devices 130 are directly connected to the controller 110 through the communication bus 120, so that the topology transmission of the control signal can be simplified and the anti-interference capability of the control signal can be enhanced. Meanwhile, the laser embroidery device 10 can independently control each laser device 130 based on the communication bus 120, so that the laser control is more flexible and the installation is simple.

In an alternative embodiment, the laser device 130 includes a plurality of laser devices 130, and each of the plurality of laser devices 130 is communicatively coupled to the controller 110 via the communication bus 120.

Wherein each laser device 130 includes only one laser embroidery head 131. Therefore, by directly connecting the laser device 130 with the controller 110 in a communication manner, the controller 110 can independently control each laser embroidery head 131 corresponding to the laser device 130, so that the power of the laser emitted from each laser embroidery head 131 is more accurate, and the quality of the embroidery product can be improved.

Further, in some embodiments, laser device 130 may include a laser controller 132 and a laser tube 133. Laser controller 132 may be communicatively coupled to controller 110 via communication bus 120, and laser controller 132 may be coupled to laser pipe 133, where laser pipe 133 may be coupled to laser embroidery head 131. Therefore, the controller 110 may send a control signal to the laser controller 132, and the laser controller 132 may control the laser pipe 133 to send corresponding laser from the position of the laser embroidery head 131 according to the control signal, so that the laser embroidery head 131 may perform a laser embroidery operation.

Specifically, the control signal sent by the controller 110 to the laser device 130 through the communication bus 120 may be a digital signal, wherein the laser controller 132 may generate a corresponding laser control signal according to the digital signal, and the laser pipe 133 may emit a laser beam with a corresponding power according to the laser control signal, and the laser beam passes through the laser embroidery head 131, so as to perform a laser embroidery operation.

In some embodiments, the laser controller 132 may be a control circuit board that is connected to the laser tube 133.

Referring to fig. 1 and 2, fig. 2 is a schematic diagram of a frame structure of an embodiment of a laser device in the laser embroidery device shown in fig. 1, and fig. 2 is a schematic diagram of a circuit structure of a laser controller 132 in the laser embroidery device shown in fig. 1. In some embodiments, referring to fig. 1 and 2, the laser controller 132 may include a decoding circuit (not shown), a signal latch circuit 1321, and a digital signal conversion circuit 1322.

Wherein, the input terminal of the decoding circuit can be connected to the communication bus 120, so as to receive the digital signal transmitted by the communication bus 120. The digital signal transmitted by the communication bus 120 is a serial digital signal having N bits. The decoding circuit can receive the serial digital signal of N bits, thereby converting the serial digital signal into a parallel digital signal.

For example, when the digital signal transmitted through the communication bus 120 is an N-bit digital signal, the decoding circuit can decode the N-bit serial digital signal when the N-bit digital signal is sequentially transmitted in series to the decoding circuit, so that the parallel N-bit digital signal can be formed. Alternatively, the decoding circuit may decode the serial digital signal of N bits to form two sub-parallel digital signals in series, each having a digital signal of N/2 bits in parallel. Or, four serial sub-parallel digital signals are formed, and each sub-parallel digital signal has an N/4 bit parallel digital signal.

Wherein the decoding circuit may determine the number of sub-parallel digital signals and the number of bits of each sub-parallel digital signal according to the number of bits of the parallel transmission line connected thereto.

When the decoding of the serial digital signal of N bits is completed, the formed parallel digital signal may be transmitted to the signal latch circuit 1321 to be latched.

In this embodiment, a scheme in which a serial digital signal of N bits is decoded by a decoding circuit to form two serial sub-parallel digital signals, and each sub-parallel digital signal has a digital signal of N/2 bits in parallel is taken as an example.

The latch circuit 1321 includes a parallel transmission line 141, two first-stage latches 142, two second-stage latches 143, a first latch trigger circuit 144, and a second latch trigger circuit 145.

The two first-stage latches 142 may be connected to the parallel transmission line 141, and the two second-stage latches 143 are connected to the two first-stage latches 142 in a one-to-one correspondence. The first latch trigger circuit 144 includes two sub-latch trigger circuits 1441, and the two sub-latch trigger circuits 1441 are respectively connected to the two first-stage latches 142; a second latch trigger circuit 145 may then be connected to both second stage latches 143.

Specifically, when the decoding circuit forms two serial sub-parallel digital signals, the two sub-parallel digital signals may be serially transmitted to the two first-stage latches 142 along the parallel transmission line 141. The two sub-parallel digital signals may correspond to a high-order digital signal and a low-order digital signal of the N-order serial digital signal, respectively.

When the first sub-parallel digital signal is transmitted to one of the first-stage latches 142, the first latch trigger circuit 144 connected thereto sends out a latch signal, so that the first-stage latch 142 latches the sub-parallel digital signal; when the second sub-parallel digital signal is transmitted to another first-stage latch 142, the first latch trigger circuit 144 connected thereto issues a latch signal, so that the first-stage latch 142 latches the second sub-parallel digital signal.

The two first-stage latches 142 may further transfer the sub-parallel digital signals respectively latched to the two second-stage latches 143 respectively connected thereto. Then, the second latch trigger circuit 145 may simultaneously send out a latch signal to the two second-stage latches 143, so that the two second-stage latches 143 respectively latch the sub-parallel digital signals received by them.

The two second-stage latches 143 may be connected to the input terminals of the digital signal converting circuit 1322, so that the two sub-parallel digital signals respectively latched by the two second-stage latches may be simultaneously transmitted to the digital signal converting circuit 1322, so that the digital signal converting circuit 1322 may receive the N-bit parallel digital signal.

The digital signal conversion circuit 1322 may further perform subsequent processing on the N-bit parallel digital signal received by the digital signal conversion circuit, so as to convert the N-bit parallel digital signal into a corresponding laser control signal, and further send the converted laser control signal to the laser tube 133. To enable control of the laser tube 133.

In this embodiment, the laser control signal may be a voltage signal for controlling the operation of the laser tube 133, so that the operating voltage of the laser tube 133 may be adjusted by the laser control signal, so that the laser tube 133 may emit laser with a power corresponding to the laser control signal. And by providing different digital signals, the laser tube 133 can be caused to emit laser light with corresponding power at different operating voltages.

In this embodiment, the two sub-parallel digital signals may respectively correspond to a high-bit digital signal and a low-bit digital signal of the N-bit serial digital signal. When the voltage signal of the laser tube 133 is adjusted, the high-order digital signal and the low-order digital signal are respectively latched in the two first-stage latches 142 in a sub-order, and then the second latch trigger circuit 145 sends out latch signals to the two second-stage latches 144 at the same time, so that the high-order digital signal and the low-order digital signal are latched to the two second-stage latches 144 at the same time, and thus the problem that the overall output of the digital signal fluctuates when the high-order or low-order data signal is latched only in one stage can be avoided, the accuracy of transmitting the digital signal to the digital signal conversion circuit 1322 can be improved, and the control accuracy of controlling the working voltage of the laser tube 133 can be improved.

Further, in some embodiments, the laser tube 133 includes a power supply module and a light emitting module, the power supply module is electrically connected to the light emitting module, and the power supply module can supply power to the light emitting module, so that the light emitting module emits laser light. The power supply module can be used for externally connecting an external power supply, converts the external power supply into corresponding working voltage, supplies the working voltage to the light-emitting module, and the light-emitting module can emit laser with power corresponding to the working voltage.

In this embodiment, the output terminal of the digital signal conversion circuit 1322 may be electrically connected to the power supply module of the laser tube 133. The digital signal conversion circuit 1322 may send the converted laser control signal to the power supply module of the laser tube 133, so that the power supply module of the laser tube 133 may adjust the operating voltage provided to the light emitting module according to the laser control signal.

Further, in some specific embodiments, the laser device 130 may further include an adjustment button 135, wherein the adjustment button 135 may be coupled to the laser controller 132, and a fine adjustment signal may be triggered by the adjustment button 135 and sent to the laser controller 132, and when the laser controller 132 receives the fine adjustment signal, the laser controller 132 performs fine adjustment on the laser control signal sent to the power supply module according to the fine adjustment signal.

For example, when the laser control signal is a voltage signal, the laser controller 132 may send a first voltage signal having a first voltage value to the power supply module of the laser tube 133 according to the control signal sent by the controller 110, and at this time, the power supply module may adjust the operating voltage provided by the power supply module to the light emitting module in response to the first voltage signal. If the operating voltage provided by the power supply module to the light emitting module still has a deviation, a fine tuning signal may be sent to the laser controller 132 through the adjustment button 135, and the laser controller 132 may perform fine tuning on the voltage value of the first voltage signal according to the fine tuning signal, so as to generate a second voltage signal having a second voltage value, and the power supply module may provide the operating voltage to the light emitting module in response to the second voltage signal.

The adjustment button 135 may be a coding switch, such as a knob-type coding switch or a dial switch.

In another aspect of the present application, a control method of a laser embroidering apparatus is also provided. Referring to fig. 3, fig. 3 is a flowchart illustrating a control method of a laser embroidery device according to an embodiment of the present application.

The control method of the laser embroidering device in the embodiment may be implemented based on the laser embroidering device described above, wherein the control method of the laser embroidering device includes the following steps:

s110: and establishing communication connection between the laser device and the controller through a communication bus.

In the step, the laser device and the controller can be in communication connection through the communication bus, so that the controller can send a control signal to the laser device through the communication bus, the topological transmission of the control signal is simplified, and meanwhile, the interference and attenuation of the control signal in the transmission process are reduced.

The number of the laser devices can be multiple, and the multiple laser devices can be connected with the communication bus, so that the communication bus is in communication connection with the controller.

Wherein each laser device only comprises one laser embroidery head.

S120: control signals are provided to the laser devices by the controllers, respectively.

In this step, the controller may send a control signal to the laser device through the communication bus. Wherein the controller may send a serial digital signal to the laser device over the communication bus. Different control signals can be respectively transmitted to the plurality of laser devices in a serial transmission mode, so that the laser embroidery heads in each laser device can be independently controlled.

S130: the laser device performs embroidery operation according to the control signal.

The laser device may specifically refer to the laser device 130 described above, and the laser device includes a laser controller and a laser tube, wherein the laser embroidery head is connected to the laser tube. The laser controller can receive the control signal sent by the controller, convert the control signal into a laser control signal, and send the laser control signal to the laser tube, so that the working voltage of the laser tube can be controlled, and the laser tube can send laser with the power corresponding to the laser control signal. And the laser device and the article to be embroidered move relatively according to a preset path under the control of the control signal, so that the embroidery is performed. It can be understood that the article to be embroidered is fixed, and the laser device drives the laser embroidery head to move according to a preset path under the control of the control signal; or the laser device is fixed, and the article to be embroidered moves according to a preset path under the control of the control signal.

In some embodiments, the laser control signal may be a voltage signal for controlling the operating voltage of the laser tube, so that the operating voltage of the laser tube may be adjusted by the laser control signal, thereby adjusting the power of the laser emitted by the laser embroidery head, and enabling the laser embroidery head to output the laser at a corresponding power according to the control signal to perform an embroidery operation.

Further, in some embodiments, S130: the laser device carries out embroidery operation according to the control signal, and the method specifically comprises the following steps: the laser device converts the control signal into a voltage signal by using a secondary latching mode; the laser device emits laser with corresponding power according to the voltage signal; the laser device performs embroidery according to a set path at the power.

The laser controller of the laser device may include a decoding circuit, a signal latch circuit, and a digital signal conversion circuit, as described above. Therefore, the second-stage latch of the control signal decoded by the decoding circuit can be implemented by the signal latch circuit, where the specific manner of the second-stage latch may refer to the related content of the signal latch circuit 1321, which is not described herein again.

In an optional embodiment, the emitting, by the laser device, laser light with corresponding power according to the voltage signal may specifically include: the laser device is preset with each voltage signal and the set power corresponding to each voltage signal; after receiving the voltage signal, the laser device can search the set power corresponding to the voltage signal, and then emit laser according to the searched set power. Through the scheme, the corresponding set power can be directly called out, the program is simple, and the reaction is quick. However, this method is not versatile and can be operated only in accordance with a set voltage signal. Once a new voltage signal appears, the adjustment cannot be performed in time.

Based on the above analysis, in another embodiment, the emitting the laser with the corresponding power by the laser device according to the voltage signal may specifically include: the laser device is provided with a preset voltage signal; the laser device can judge and analyze the preset voltage signal and the actual voltage signal after receiving the actual voltage signal, and adjust the actual voltage signal according to the preset voltage signal.

Specifically, in a specific embodiment, the laser device may have a plurality of preset voltage signals and set powers respectively corresponding to the plurality of preset voltage signals; when the laser device receives the actual voltage signal, the actual voltage signal can be matched with a plurality of preset voltage signals, and if the actual voltage signal is judged to be matched with one of the preset voltage signals, the laser tube can be enabled to emit laser at the set power corresponding to the preset voltage signal. If the actual voltage signal is not matched with the preset voltage signals, the preset voltage signal with the minimum deviation with the actual voltage signal can be selected, the actual voltage signal is adjusted to be consistent with the preset voltage signal with the minimum deviation, and the laser tube emits laser at the set power corresponding to the preset voltage signal. The working voltage of the laser tube when the laser tube operates according to the actual voltage signal is the working voltage of the laser tube; and the working voltage of the laser tube when the laser tube operates according to the preset voltage signal is the corresponding preset working voltage of the laser tube. The minimum deviation between the actual voltage signal and the preset voltage signal means that the voltage difference between the actual voltage signal of the laser tube and the preset working voltage is minimum.

Of course, in another specific embodiment, the laser device sets a preset voltage signal and a set power corresponding to the preset signal, and sets a relationship between a change in the voltage signal and a change in the set power. When the laser device receives an actual voltage signal, the actual voltage signal is matched with a preset voltage signal, the difference value of the actual voltage signal and the preset voltage signal is judged, and then the relative change is carried out on the basis of the set power according to the relation between the set voltage signal change and the set power change, so that the actual light-emitting power of the laser device for controlling the laser can be obtained.

The laser device described above adjusts and emits the laser with the corresponding power according to the voltage signal, and the actual voltage signal transmitted by the laser controller fluctuates to adjust the actual voltage signal, so that the laser tube can output the laser with the power corresponding to the actual voltage signal or with the minimum deviation, and the influence on the quality of the embroidery product caused by the overhigh or overlow laser energy is avoided.

Because a plurality of laser devices are in communication connection with the controller through a communication bus, identification is facilitated, or control signals of the controller are conveniently and accurately and quickly transmitted to the corresponding laser devices. In some embodiments, the identity mark of each laser device may be set, and the control signal sent by the controller includes only the identity mark of one laser device, so that the controller may send the control signal to the corresponding laser device according to the identity mark, so as to individually and precisely control each laser device.

In summary, in the embodiment of the present application, a plurality of laser devices in a laser embroidery device are directly connected to a controller through a communication bus, so that the controller can directly send a control signal to each laser device, and thus each laser device can be controlled independently. According to the scheme, the plurality of laser devices are directly in communication connection with the controller through the communication bus, so that topological transmission of control signals can be simplified, and the anti-interference capacity of the control signals is enhanced. Meanwhile, each laser device can be independently controlled based on the communication bus, so that the laser control is more flexible and the laser embroidery device is simple to install.
