Detailed Description

In order to make the technical problems solved, the technical solutions adopted and the technical effects achieved by the present invention clearer, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.

It should be noted that, in the present embodiment, the term "cutting" may generally refer to changing the appearance, properties and/or morphology of a material. Cutting may include, for example, cutting through, engraving, burning, and the like. Engraving, when used in this embodiment, represents the process by which a three-dimensional automated device changes the appearance of a material without cutting through it. For example, for a laser cutter, it may mean removing some material from a surface, discoloring a material by applying electromagnetic radiation, and the like.

In the present embodiment, the term "laser" includes any source of electromagnetic radiation or focused or coherent energy (in the case of a cutting tool) that uses photons to cause some change or alteration in the surface substrate or material affected by the photons. The laser (whether a cutting tool or a diagnostic) may be of any desired wavelength, including, for example, microwave, laser, infrared laser, visible laser, UV laser, X-ray laser, gamma ray laser, and the like.

Example one

Referring to fig. 1, the present embodiment provides a laser module, which is applied to a laser engraving and cutting system, and emits laser as a laser emitting component to perform engraving and cutting on a workpiece.

Specifically, in the present embodiment, the laser module includes the laser 1 and a posture detection system of the laser. The attitude detection system of the laser is used for controlling the working state of the laser. Specifically, the posture detection system of the laser can control the working state of the laser 1, and avoid the laser 1 from emitting laser beams when the posture is improper (for example, emitting laser beams towards a human body) to cause injury to a user.

Specifically, the laser 1 is a laser module that emits a laser beam.

Specifically, the posture detection system of the laser includes a memory, a posture detection unit 2, and a controller.

Wherein the memory has stored therein a tilt threshold.

The attitude detection unit 2 is used for detecting and obtaining an attitude value of the laser, and the attitude detection unit 2 is in communication connection with the memory and can compare the attitude value with a tilt threshold value; specifically, the posture detecting unit 2 is mounted on the laser 1.

The controller is in communication connection with the attitude detection unit 2, the attitude detection unit 2 transmits a comparison result of the attitude value and the inclination threshold value to the controller, and the controller can control the working state of the laser according to the comparison result; the controller is configured to: when the attitude numerical value is greater than the inclination threshold value, controlling the working state of the laser to be a non-openable state; otherwise, controlling the working state of the laser to be in a selective starting state.

In the posture detection system of the laser provided by this embodiment, when the posture detection unit 2 compares the posture value with the tilt threshold, the comparison result is transmitted to the controller, and if the posture value is greater than the tilt threshold, it indicates that the posture of the laser 1 is incorrect, and the laser beam may cause injury to the human body, at this time, the controller controls the working state of the laser 1 to be the non-openable state, that is, if the laser is not opened at this time, the laser cannot be opened; and if the working state of the laser is the on state at the moment, the controller directly switches the laser to the off state. If the posture value is not greater than the inclination threshold, the posture of the laser is correct, the laser beam emitted by the laser cannot be irradiated on a human body, and at the moment, the user can turn on the laser 1 or turn off the laser 1 as required.

Further, in order to prompt the user, in this embodiment, the controller can be in communication with a display of the laser cutting engraving system.

When the attitude value is greater than the tilt threshold, the controller can transmit the comparison result of the attitude detection unit 2 to the display to warn the user that the laser 1 cannot be turned on. Alternatively, when the gesture value is not greater than the tilt threshold, the controller can transmit the comparison result of the gesture detection unit 2 to the display to indicate to the user that the laser 1 can be turned on.

Preferably, in the present embodiment, the posture detecting unit 2 is a gyroscope.

Example two

The present embodiment provides a method for controlling the on/off of a laser, which uses the posture detection system of the laser in the first embodiment to control the working state of the laser 1 of the laser cutting engraving system.

Specifically, in this embodiment, the method for controlling the switching of the laser includes:

s1, the attitude detection unit 2 detects and obtains the attitude value of the laser 1, and compares the attitude value with the inclination threshold value stored in the memory;

s2, the attitude detection unit 2 compares whether the attitude value is larger than the inclination threshold value, if so, the comparison result is sent to the controller, and the controller controls the working state of the laser 1 to be a non-openable state; otherwise, the comparison result is sent to the controller, and the controller controls the working state of the laser 1 to be in the selective starting state.

In the method for controlling the on/off of the laser device provided in this embodiment, the posture detection system of the laser device in the first embodiment is used to control the working state of the laser device 1 of the laser cutting engraving system. When the attitude detection unit 2 compares the attitude value with the inclination threshold value, the comparison result is transmitted to the controller, if the attitude value is greater than the inclination threshold value, the attitude of the laser 1 is incorrect, the laser beam may cause damage to a human body, and the controller controls the working state of the laser 1 to be a non-openable state, namely, if the laser is not opened at the moment, the laser cannot be opened; and if the working state of the laser is the on state at the moment, the controller directly switches the laser to the off state. If the posture value is not greater than the inclination threshold, the posture of the laser is correct, the laser beam emitted by the laser cannot be irradiated on a human body, and at the moment, the user can turn on the laser 1 or turn off the laser 1 as required.

Further, in order to prompt the user, in step S2, when the controller controls the operating state of the laser 1 to be the non-turn-on state, the controller transmits the comparison result to the display of the laser cutting engraving system, and the display can warn the user that the laser 1 is not turned on. Optionally, the display can pop up a pop-up window to alert the user that the laser 1 is not available to turn on.

Specifically, the laser cutting and engraving system has a starting state and a working state. In step S2, if the laser cutting and engraving system is in the on state, the gesture detection unit 2 compares that the gesture value is greater than the tilt threshold, and the laser 1 cannot be turned on. In step S2, if the gesture detection unit 2 compares that the gesture value is greater than the tilt threshold value when the laser cutting engraving system is engraving, the laser 1 is switched from the on state to the off state.

Specifically, when the laser cutting engraving system is in a power-on state, the posture detection unit 2 compares the obtained posture value with a tilt threshold value, which indicates that the laser 1 is not correctly installed, and the controller controls the laser 1 not to be turned on. The display of the laser cutting engraving system can pop up a popup window of 'incorrect installation of the execution head', and the popup window prompts that the laser is not correctly installed.

When the display of the laser cutting engraving system pops up a popup window of which the execution head is not correctly installed, if a user closes the popup window, the display displays a main page, the user can perform other screen operations without using laser, and when the user performs related operations requiring laser, the popup window pops up again to prompt that the laser is not correctly installed. If the user adjusts the posture of the laser to the correct position, the posture detection unit 2 detects that the laser 1 is correctly installed, and at this time, the laser-related operation can be started.

When the display of the laser cutting engraving system pops up the popup window of which the execution head is not correctly installed, if the user does not close the popup window and adjusts the posture of the laser to the correct position, the posture detection unit 2 detects that the laser 1 is correctly installed, the popup window disappears, and at the moment, the laser related operation can be started.

Specifically, when the laser cutting engraving system works normally, the laser 1 emits laser normally, if the posture of the laser 1 is incorrect due to careless touch on the laser 1, the posture detection unit 2 detects that the laser 1 is not installed correctly, the laser is turned off, the work of the laser cutting engraving system is suspended, and a suspension button on the display is automatically changed into a recovery button; at the same time, the display pops up a popup window that the execution head is not correctly installed.

When the display pops up the popup window of 'the execution head is not correctly installed', if the popup window is closed, the display returns to the working page. After the display returns to the work page, if the user clicks the recovery button, the display pops up the popup window of 'the execution head is not installed correctly'. After the display is returned to the work page, the user may perform other screen operations that do not require the use of a laser. If the user adjusts the posture of the laser to the correct position, the posture detection unit 2 detects that the laser 1 is correctly installed, and at this time, the laser-related operation can be started.

When the display pops up the popup window of which the execution head is not correctly installed, if a user does not close the popup window and adjusts the posture of the laser to the correct position, the posture detection unit 2 detects that the laser 1 is correctly installed, the popup window disappears, at the moment, a recovery button on the display is clicked, and the laser cutting engraving system recovers to work.

The foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but rather is susceptible to various changes and modifications without departing from the spirit and scope of the invention, which changes and modifications are within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
