[0057] The realization of the object of the present invention, functional features and advantages will be further described in conjunction with the embodiments with reference to the accompanying drawings. Detailed implementation manners

[0058] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0059] It should be noted that if all the directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture, if the specific posture changes, the directional indications will also change accordingly.

[0060] If the descriptions such as "first" and "second" in the present invention are only for the purpose of description, they cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. If the description "A and / or B" is involved in the present invention, it means including solution A or solution B, or including both solution A and solution B. In addition, the technical solutions between the embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0061] Currently, when using a laser processing device to process a screen frame, the position of the screen frame is displayed through software of other control devices such as a host computer or a terminal device communicatively connected to the laser processing device, which can assist the user in placing the processing pattern at the corresponding position of the processable area of the screen frame or other positions in the processing area of the laser processing device in the software, helping to process the processing pattern and the like in the processable area of the screen frame conveniently and efficiently.

[0062] Since some existing laser processing equipment is not equipped with a camera and requires users to assemble it themselves, and more or less structural errors will occur during the process of users assembling the equipment, and there are also inevitable tolerances in the production process of each screen frame, the processable area of the screen frame displayed in the software is not accurate.

[0063] To solve the problem that in the usage scenario of laser processing equipment with screen frame printing, due to assembly errors, structural errors occur, and due to the inaccurate position of the processable area of the screen frame relative to the processing area of the laser processing equipment, the position of the processable area of the screen frame displayed in the display interface is not accurate. Referring to Figures 1 to 8 This application proposes a method, device, system and storage medium for determining the processable area of a screen frame. Specifically, it provides a method for determining the processable area of a screen frame, a terminal device, a laser processing device, a laser processing system and a computer-readable storage medium, so as to accurately determine the processable area of the screen frame in the display interface, ensure that during laser processing, the processing pattern placed in the software of a control device such as a host computer can be accurately set to the corresponding position of the processable area of the screen frame, to accurately position the processing and ensure the aesthetics of the processing effect.

[0064] In the embodiment provided by this application, referring to Figure 3 The method for determining the processable area of the screen frame includes the following steps:

[0065] Step S100: In response to the received origin calibration instruction, obtain the processing origin of the processing area of the laser processing equipment and determine the origin of the screen frame;

[0066] Step S200: Obtain the size of the screen frame;

[0067] Step S300: Determine the processable area of the screen frame in the display interface according to the positional relationship between the processing origin of the processing area of the laser processing equipment and the origin of the screen frame, and the size of the screen frame.

[0068] The method for determining the processable area of the screen frame shown in this application is applied to laser processing equipment, laser processing systems, etc.

[0069] Position calibration is performed according to the positional relationship between the processing origin of the laser processing equipment and the origin of the screen frame, which can solve the position errors caused by equipment assembly errors and the relative position differences between the processing area of the laser processing equipment and the screen frame, and accurately determine the position of the processable area of the screen frame in the display interface of the host computer software, so that the processing pattern set in the display interface can be accurately mapped to the corresponding position of the processable area of the screen frame or the processing area of the laser processing equipment, ensuring the accuracy of the processing position and making the processing effect more beautiful.

[0070] In some embodiments of the present application, the laser processing device is provided with a camera device, an encoder, a laser head, etc. as positioning devices. After determining the processable area of the screen frame in the display interface through the positioning devices of the laser processing device, a processing pattern is set on the processable area of the screen frame in the display interface, and then the processing head can be further controlled to process the target processing pattern at the corresponding position during subsequent processing. In this way, the accuracy of the processing position and the aesthetics of the processing effect can be ensured.

[0071] When responding to the received origin calibration instruction in step S100, calibration preparation can be performed to respond to the received origin calibration instruction, obtain the processing origin of the processing area of the laser processing device, and determine the origin of the screen frame. The user can input the origin calibration instruction or other instructions for starting calibration by clicking an operation button or the like to output the origin calibration instruction, and the calibration is started by a control device such as a host computer. The operation button shown can be, but is not limited to, a mechanical button or a form of an operation button displayed on the operation interface. In addition, the start calibration signal shown can also be automatically generated after the laser processing device is started, and the control device such as the host computer and the terminal device executes step S100 according to the start calibration signal shown. Specifically, it can be set according to the actual situation and is not limited here.

[0072] In a specific embodiment of the present application, referring to Figure 4 , the obtaining of the processing origin of the processing area of the laser processing device in step S100 includes the following steps:

[0073] Step S110: Send a return-to-origin instruction to the laser processing device, and in response to the instruction fed back after the laser processing device returns to the origin, obtain the current coordinates of the laser processing device, and determine the current coordinates of the laser processing device as the processing origin of the processing area of the laser processing device.

[0074] Send a return-to-origin instruction to the laser processing device to drive the laser module of the laser processing device to return to the origin. After the laser module of the laser processing device returns to the origin, in response to the instruction fed back after the laser processing device returns to the origin, determine the current coordinates of the laser processing device as the processing origin of the processing area of the laser processing device.

[0075] The coordinates of the above laser processing equipment are absolute coordinates. After the laser processing equipment is started, it is not excluded that the coordinate position of the processing origin of the processing area of the laser processing equipment stored before the previous power-off is used as the processing origin. Since the positions where the lasers are emitted by laser modules with different wattages are different, and in the cases of replacing the screen frame, replacing the laser module, or powering on again, there are deviations, and the processing origin of the processing area of the original laser processing equipment and the processing origin of the current laser processing equipment may not be corresponding. By returning to the origin to re-determine the processing origin of the processing area of the laser processing equipment, it can be used to re-obtain the processing origin of the processing area of the laser processing equipment and re-determine the origin of the screen frame every time the equipment is adjusted, the screen frame is replaced, etc., which will affect the determination of the processable area of the screen frame.

[0076] In one embodiment, referring to Figure 4 , determining the origin of the screen frame in step S100 includes the following steps:

[0077] Step S120, in response to the instruction fed back after the light emitted by the laser processing equipment is aligned with the origin of the screen frame, obtain the current coordinates of the laser processing equipment according to the coordinate system corresponding to the processing origin of the processing area of the laser processing equipment, and determine the origin of the screen frame according to the current coordinates of the laser processing equipment;

[0078] Among them, the origin of the screen frame includes at least one of the boundary points of the screen frame, the center of the circle of the screen frame, the center point of the screen frame, and the key point of the screen frame.

[0079] When performing the above step S120, the user can input an instruction by clicking an operation button or the like to control the movement of the processing head of the laser processing equipment, so that the light emitted by the laser processing equipment is aligned with the origin of the screen frame. After the light emitted by the laser processing equipment is aligned with the origin of the screen frame, the laser processing equipment automatically generates an instruction for feeding back that the light emitted by the laser processing equipment is aligned with the origin of the screen frame; or, the user directly moves the processing head of the laser processing equipment to align the light emitted by the laser processing equipment with the origin of the screen frame and coincide with the origin of the screen frame, and after the light emitted by the laser processing equipment is aligned with the origin of the screen frame, input an instruction for determining that the light emitted by the laser processing equipment is aligned with the origin of the screen frame through a mechanical button provided on the laser processing equipment or an operation control on the display interface.

[0080] The coordinates of the laser processing equipment are absolute coordinates. By designating any one or more points of the screen frame as the origin of the processable area of the screen frame, obtaining the current coordinates of the laser processing equipment according to the coordinate system corresponding to the processing origin of the processing area of the laser processing equipment, and determining the origin of the screen frame with the current coordinates of the laser processing equipment, it is used to determine the origin of the screen frame according to the relative position between the origin of the screen frame and the processing origin of the laser processing equipment.

[0081] It should be noted that any one or more points of the specified screen frame are designated as the origin of the screen frame. The origin of the screen frame includes at least one of the boundary points of the screen frame, the center of the circle of the screen frame, the center point of the screen frame, and the key point of the screen frame. When the origin of the screen frame is the boundary point of the screen frame and the screen frame is a rectangular screen frame, it can be the upper left corner, upper right corner, lower left corner, lower right corner, etc. of the screen frame. The boundary point of the screen frame can be any point that can determine or infer the boundary of the screen frame, and is not uniquely limited here. The number of origins of the processable area of the screen frame can be one, or two, three, etc., and is not uniquely limited here.

[0082] In the embodiment of the present application, first drive the laser module of the laser processing equipment to return to the origin. After obtaining the processing origin of the processing area of the laser processing equipment, control the movement of the processing head of the laser processing equipment, so that the processing components or positioning components, etc. of the processing head (or laser module) that have the function of light output calibration emit light and align with the origin of the screen frame, and determine the current coordinates of the laser processing equipment as the origin of the screen frame according to the coordinate system corresponding to the processing origin of the processing area of the laser processing equipment and the direction and distance of the movement of the processing head. In order to simplify the user operation and ensure that the light output quickly and accurately aligns with the origin of the screen frame, the approximate direction of the origin of the processable area of the screen frame can be preset in advance through a control device such as a host computer. After obtaining the origin of the processing area of the laser processing equipment, the processing head is controlled to move a preset distance in the direction of the origin of the screen frame first. In this way, the user only needs to finely adjust the position of the processing components or positioning components, etc. of the processing head (or laser module), and then the light output of the laser processing equipment can be aligned with the origin of the screen frame, and further determine the origin of the processable area of the screen frame.

[0083] In addition, an auxiliary pattern or other auxiliary positioning structure can be pasted at the origin of the screen frame in advance to assist in positioning. Refer to Figure 1 , taking the screen frame as a rectangular screen frame as an example, specifically, the upper right corner of the screen frame 40 or one or more other points can be designated as the origin of the processable area 30 of the screen frame, so as to facilitate the light output of the laser processing equipment to align with the origin of the processable area 30 of the screen frame, help the user quickly align the light output point 10 of the laser processing equipment with the auxiliary pattern 20, and determine the origin of the screen frame according to the coordinates of the laser processing equipment when the light output point 10 aligns with the auxiliary pattern 20.

[0084] It should be noted that, according to the actual situation, optionally, the shown auxiliary graphics or other auxiliary positioning structures are set to signal emission components with radio frequency functions. When there is an auxiliary positioning structure with radio frequency functions at the origin of the screen printing frame, after the laser processing equipment aligns the light output with the origin of the processable area 30 of the screen printing frame, the position signal feedback by the auxiliary positioning structure is obtained, and in response to the position signal feedback by the auxiliary positioning structure, the origin of the screen printing frame is determined based on the current coordinates of the laser processing equipment, so as to determine the relative position between the origin of the screen printing frame and the origin of the processing area of the laser processing equipment.

[0085] In one embodiment, the laser processing equipment is provided with a processing component and a positioning component, and the processing component and the positioning component are used for light output calibration. Different processing components and positioning components can be configured in the processing head (or in the laser module). The processing component can be used for processing such as laser etching and can also be used for emitting weak light. The positioning component can emit a cross-shaped light spot and other light-emitting points to indicate the processable area of the screen printing frame.

[0086] Refer to Figure 5 , in step S120, obtaining the current coordinates of the laser processing equipment according to the coordinate system corresponding to the processing origin of the processing area of the laser processing equipment, and determining the origin of the screen printing frame according to the current coordinates of the laser processing equipment, includes:

[0087] Step S121, when the laser processing equipment emits light through the processing component and determines that the light output of the processing component is aligned with the origin of the screen printing frame, obtain the current coordinates of the processing component according to the coordinate system corresponding to the processing origin of the processing area of the laser processing equipment, and determine the current coordinates of the processing component as the origin coordinates of the screen printing frame;

[0088] Step S122, when the laser processing equipment emits light through the positioning component and determines that the light output of the positioning component is aligned with the origin of the screen printing frame, obtain the current coordinates of the positioning component according to the coordinate system corresponding to the processing origin of the processing area of the laser processing equipment, and calculate and determine the origin coordinates of the screen printing frame according to the current coordinates of the positioning component and the deviation distance between the positioning component and the processing component.

[0089] It can be understood that since the processing component and the positioning component are installed at different positions of the laser module, therefore, when using the processing component to align the light output with the origin of the screen printing frame, the coordinates of the laser module obtained by the host computer software at this time (the current coordinates of the processing component) can be directly used as the origin coordinates of the screen printing frame. When using the positioning component to align the light output with the origin of the processable area of the screen printing frame, the coordinates of the laser module obtained by the host computer software at this time (the current coordinates of the positioning component) need to be further converted, and can be used as the origin coordinates of the screen printing frame only after offsetting the deviation distance between the processing component and the positioning component or other actually set installation distances at the algorithm level.

[0090] In an embodiment of the present application, the processable area of the screen frame is not larger than the actual area of the screen frame.

[0091] As an embodiment of the present application, when the processable area of the screen frame is the actual area of the screen frame, referring to Figure 6 , step S300, determining the processable area of the screen frame in the display interface according to the positional relationship between the processing origin of the laser processing equipment processing area and the origin of the screen frame, and the size of the screen frame includes the following steps:

[0092] Step S311, determining the coordinates of multiple boundary points of the screen frame according to the positional relationship between the processing origin of the laser processing equipment processing area and the origin of the screen frame, and the size of the screen frame;

[0093] Step S312, associating the coordinates of the multiple boundary points to determine the processable area of the screen frame in the display interface.

[0094] It is used to directly take the format of the screen frame as the processable area of the screen frame. Specifically, according to the positional relationship between the processing origin of the processing area of the processing equipment and the origin of the screen frame, and the size of the screen frame, determine the positional relationship of multiple boundary points of the screen frame relative to the processing origin of the processing area of the laser processing equipment. After determining the coordinates of multiple boundary points of the screen frame, by associating the coordinates of the multiple boundary points, specifically, by connecting the coordinates corresponding to the multiple boundary points, the processable area of the screen frame can be determined in the display interface.

[0095] Optionally, determine the processing origin of the processing area of the laser processing equipment (assuming the coordinates are (0, 0)) by returning to the origin. Determine the origin of the screen frame (assuming it is (x, y)) based on the coordinate system created with the processing origin of the processing area of the laser processing equipment as (0, 0). According to the set size of the screen frame, determine the boundary point coordinates of the screen frame. When the screen frame is rectangular (the length of the screen frame is a and the width is b), the coordinates of each boundary point in the x direction are between x - a and x + a; the coordinates of each boundary point in the y direction are between y - b and y + b. Specifically, taking the screen frame as rectangular and taking the boundary point in the upper left corner of the screen frame as the origin of the screen frame, and determining the origin of the screen frame (x, y) based on the coordinate system created with the processing origin (0, 0) of the processing area of the laser processing equipment, according to the set size of the screen frame (the length of the screen frame is a and the width is b), the coordinates of the four boundary points of the processable area of the screen frame can be determined as (x, y), (x + a, y), (x, y - b), (x, y - b) respectively. Then connect the adjacent boundary points in sequence, and the position of the processable area of the screen frame on the processing area of the processing equipment can be determined, and further determine the processable area of the screen frame in the display interface.

[0096] As another embodiment of the present application, when the processable area of the screen frame is smaller than the actual area of the screen frame, referring to Figure 7 , before performing step S300, which is to determine the processable area of the screen frame on the display interface according to the positional relationship between the processing origin of the laser processing equipment processing area and the origin of the screen frame, and the screen frame size, the method further includes:

[0097] Step S301: Obtain the edge reserved size of the screen frame;

[0098] Step S300: Determining the processable area of the screen frame on the display interface according to the positional relationship between the processing origin of the laser processing equipment processing area and the origin of the screen frame, and the screen frame size includes the following steps:

[0099] Step S320: Determine the processable area of the screen frame on the display interface according to the positional relationship between the processing origin of the laser processing equipment processing area and the origin of the screen frame, the size of the screen frame, and the edge reserved size.

[0100] It can be understood that to achieve better processing effects such as engraving and printing, a certain space should be reserved between the processed pattern and the edge of the screen frame. In this way, it helps to reserve enough elasticity for the screen surface to achieve a better screen printing effect. The actual size of the screen frame is different, and the processable area of the screen frame will also be different. In the example of the present application, the preset edge reserved size can be, but is not limited to, pre-set by control device software such as a host computer or a terminal device. By setting the edge reserved size, it is used to optimize the processing effect.

[0101] Specifically, in one embodiment, when the screen frame is rectangular, the edge reserved size includes a length reserved size and a width reserved size. Referring to Figure 8 , step S320: Determine the processable area of the screen frame on the display interface according to the positional relationship between the processing origin of the laser processing equipment processing area and the origin of the screen frame, the size of the screen frame, and the edge reserved size includes the following steps:

[0102] Step S321: Determine the boundary point coordinates in the length direction and the boundary point coordinates in the width direction of the screen frame according to the positional relationship between the processing origin of the laser processing equipment processing area and the origin of the screen frame, and the size of the screen frame;

[0103] Step S322: Determine the first boundary point coordinates in the length direction of the processable area of the wire mesh frame according to the boundary point coordinates in the length direction of the wire mesh frame and the length reserved dimension, and determine the second boundary point coordinates in the width direction of the processable area of the wire mesh frame according to the boundary point coordinates in the width direction of the wire mesh frame and the width reserved dimension;

[0104] Step S323: Determine the processable area of the wire mesh frame in the display interface according to the first boundary point coordinates and the second boundary point coordinates.

[0105] Determine the processable area of the wire mesh frame by subtracting the edge reserved dimension. Specifically, according to the positional relationship between the processing origin of the processing area of the processing equipment and the origin of the wire mesh frame, and the size of the wire mesh frame, determine the two first boundary point coordinates after subtracting the length reserved dimension in the length direction of the wire mesh frame, and the two second boundary point coordinates after subtracting the reserved dimension in the width direction. By correlating the two first boundary point coordinates and the two second boundary point coordinates, specifically, by connecting the two first boundary point coordinates and the two second boundary point coordinates, the processable area of the wire mesh frame can be determined in the display interface.

[0106] Optionally, determine the processing origin (assuming the coordinates are (0, 0)) of the processing area of the laser processing equipment by returning to the origin. Determine the origin (assuming it is (x, y)) of the wire mesh frame according to the corresponding coordinate system created with the processing origin (assuming the coordinates are (0, 0)) of the processing area of the laser processing equipment. According to the set size of the wire mesh frame, determine the boundary point coordinates of the wire mesh frame. When the wire mesh frame is rectangular (the length of the wire mesh frame is a and the width is b), the coordinates of each boundary point in the x direction are between x - a and x + a; the coordinates of each boundary point in the y direction are between y - b and y + b.

[0107] The length reserved dimension c1 can be set from 0.3 inches to 0.5 inches along the length direction of the screen frame, with 0.4 inches being preferred. The width reserved dimension c2 can be set from 0.8 inches to 1.3 inches along the width direction of the screen frame, with 1.0 inches being preferred, etc. Specifically, taking the screen frame as a rectangle and using the boundary point at the upper left corner of the screen frame as the origin of the screen frame, the origin (x, y) of the screen frame is determined according to the corresponding coordinate system created with the processing origin (0, 0) of the processing area of the laser processing equipment. According to the set screen frame dimensions (the length of the screen frame is a and the width is b), the coordinates of the four boundary points of the machinable area of the screen frame can be determined as (x, y), (x + a, y), (x, y - b), and (x + a, y - b) respectively. According to the boundary point coordinates in the length direction of the screen frame and the length reserved dimension c1, and the boundary point coordinates in the width direction of the screen frame and the width reserved dimension c2, the boundary point coordinates of the machinable area of the screen frame are determined as (x + c1, y - c2), (x + a - c1, y - c2), (x + c1, y - b + c2), and (x + a - c1, y - b + c2). Taking two of them as the first boundary point coordinates and the other two as the second boundary point coordinates, and then connecting the adjacent boundary points in sequence, the position of the machinable area of the screen frame on the processing area of the processing equipment can be determined, and further the machinable area of the screen frame can be determined in the display interface.

[0108] In one embodiment, the screen frame dimensions obtained in step S200 can be set by the host computer software and selected by the host computer software from a preset set of screen frame dimensions, or can be set by the user according to actual needs and determined according to the coordinate positions of multiple target points specified after the processing equipment emits light.

[0109] Wherein:

[0110] When the screen frame dimensions can be set by itself, in one embodiment, step S200, obtaining the screen frame dimensions includes the following steps:

[0111] In response to the dimension setting instruction, obtain the screen frame dimensions from the dimension setting instruction. It is used to directly determine the screen frame dimensions according to the set dimension data such as length and width.

[0112] In another embodiment, the screen frame dimensions obtained in step S200 can be determined by means such as the laser processing equipment emitting light and aligning with the boundary points of the screen frame. Taking the screen frame as a rectangle as an example, step S200, obtaining the screen frame dimensions includes the following steps:

[0113] Step S210: Obtain the first coordinates when the laser module emits light and aligns with the first boundary point of the screen frame, and obtain the second coordinates when the laser module emits light and aligns with the second boundary point of the screen frame. The first boundary point and the second boundary point are the diagonals of the screen frame.

[0114] Step S220: Determine the length and width of the screen frame according to the relative distance between the first coordinates and the second coordinates, and obtain the size of the screen frame.

[0115] When the screen frame is rectangular, specify two diagonal points of the screen frame as the target points of the processable area of the screen frame. According to the coordinates of the two points on the diagonal of the screen frame obtained before and after (i.e., any two diagonal points of the screen frame, such as the upper left corner and the lower right corner, the upper right corner and the lower left corner), determine the length and width of the screen frame by the relative distance between the coordinates of the two points, and then the size of the screen frame can be further determined.

[0116] In addition, it should be noted that when the laser processing equipment is equipped with an encoder, a camera device or other positioning devices, the processing origin of the processing area of the laser processing equipment, the origin of the screen frame and the size of the screen frame can also be obtained according to the actually set positioning devices. Among them:

[0117] Taking the laser processing equipment equipped with an encoder as an example, it can be specifically realized through the following steps:

[0118] Obtain the detection signal fed back by the encoder. The detection signal includes the processing origin of the processing area of the laser processing equipment, the origin of the screen frame and the size of the screen frame.

[0119] Taking the laser processing equipment equipped with a camera device as an example, it can be specifically realized through the following steps:

[0120] Obtain the detection image fed back by the camera device, and determine the processing origin of the processing area of the laser processing equipment, the origin of the screen frame and the size of the screen frame according to the detection image.

[0121] It can be understood that after replacing the screen frame, since the placement position of the screen frame may change and the sizes of different screen frames may also be different, therefore, after replacing the screen frame, it is necessary to recalibrate the origin of the screen frame and re-determine the processable area of the screen frame.

[0122] Furthermore, a fixing structure for the screen frame can be provided in the processing area of the laser processing equipment. The processable areas of the same screen frames (the same screen frames can refer to screen frames with the same size, the same connection structure positions and sizes to the fixing structure, etc., the same hereinafter) are also relatively fixed in the processing width area of the laser processing equipment. Therefore, when replacing the same screen frames under the condition that the processing components, positioning components, encoders, camera devices and other positioning devices of the laser module of the laser processing equipment are the same and the fixing structure for the screen frame is the same, the origin calibration does not need to be carried out. In this way, it helps to simplify the processing procedures such as screen frame printing and optimize the user experience.

[0123] In one embodiment, determining the processable area of the screen frame in the display interface includes:

[0124] Displaying the boundary line of the processable area of the screen frame on the display interface; or, highlighting the processable area of the screen frame on the display interface.

[0125] For marking the connecting lines of the boundary points of the processable area in the form of line markings or the like after determining the processable area of the screen frame to display the boundary line of the processable area of the screen frame; or directly displaying the processable area of the screen frame in a highlighted manner. By displaying the processable area of the screen frame on the display interface, it is convenient to set the target processing pattern and subsequent processing in the processable area of the screen frame.

[0126] In some embodiments of the present application, the method for determining the processable area of the above screen frame further includes the following steps:

[0127] Obtaining a calibration reference point. The calibration reference point can be highlighted in the form of a cross mark, a dot, etc. in the processable area of the screen frame on the display interface. The reference point can be set at the center or other positions in the processable area of the screen frame. The corresponding position of the processable area of the screen frame is located through the calibration reference point to facilitate setting the target processing pattern and subsequent processing in the processable area of the screen frame.

[0128] In addition, a scale, grid lines and other marks can also be displayed on the display interface to facilitate the user to preview the processable area of the screen frame.

[0129] It should be noted that the method for determining the processable area of the screen frame provided in the present application is mainly applied to DIY assembly type laser processing equipment or other laser processing equipment that needs to be calibrated before processing a pattern, so as to solve the errors caused by manual assembly during the equipment installation process and the possible influence of the structural tolerances themselves on the position of the processable area of the screen frame, and further avoid affecting the determination of the position of the processing pattern and other processing procedures such as engraving.

[0130] In some embodiments of the present application, after performing the above method for determining the processable area of the screen frame, the following steps are further included:

[0131] Obtain the position of the target processing pattern on the processable area of the screen frame and control the processing. By moving one or more target processing patterns to the processable area of the screen frame on the host computer software to facilitate subsequent processing patterns.

[0132] The present application also proposes a laser processing device. The laser processing device can be, but is not limited to, laser engraving devices such as engraving machines, laser cutting devices, and knife-cut laser processing devices. The laser processing device includes a slide rail, a processing head, a communication component, and a controller. Among them, the processing head is used to move and process the surface of the processing material by emitting a processing light spot. The processing head includes a processing component and a positioning component. The processing component and the positioning component are used for light output calibration. The processing component can be used for laser etching and can also be used for emitting weak light. The positioning component can emit a cross light spot and other light output points. The processing head can also include, but is not limited to, a laser head, a knife head, a cutting head, a pen head, and a drill bit. The processing head is slidably arranged on the slide rail; the slide rail is used to drive the processing head to reciprocate in the X direction, Y direction, and other directions. The communication component is used to receive a signal containing the processable area of the screen frame in the display interface. The signal is determined according to the steps of the above method for determining the processable area of the screen frame. The controller controls the movement of the processing head on the slide rail based on the signal to perform processing.

[0133] The present application also provides a terminal device. The terminal device includes a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, it implements the method for determining the processable area of the screen frame as described above.

[0134] The specific implementation manner of the method for determining the processable area of the screen frame that the terminal device can implement is as follows:

[0135] In response to the received origin calibration instruction, the processor sends a return-to-origin instruction to the laser processing device, and in response to the instruction fed back after driving the laser processing device to return to the origin, obtains the current coordinates of the laser processing device, and determines the current coordinates of the laser processing device as the processing origin of the processing area of the laser processing device.

[0136] The processor, in response to the instruction fed back after the laser processing device emits light and aligns with the origin of the screen frame, obtains the current coordinates of the laser processing device according to the coordinate system corresponding to the processing origin in the processing area of the laser processing device, and determines the origin of the screen frame based on the current coordinates of the laser processing device. The processing head includes a processing component and a positioning component. After controlling the processing head to move towards the origin direction of the screen frame, by finely adjusting the positions of the processing component or the positioning component of the processing head, etc., the laser processing device emits light and aligns with the origin of the screen frame. Specifically, when the laser processing device emits light through the processing component and it is determined that the light emitted by the processing component aligns with the origin of the screen frame, the current coordinates of the processing component are obtained according to the coordinate system corresponding to the processing origin in the processing area of the laser processing device, and the current coordinates of the processing component are determined as the origin coordinates of the screen frame; when the laser processing device emits light through the positioning component and it is determined that the light emitted by the positioning component aligns with the origin of the screen frame, the current coordinates of the positioning component are obtained according to the coordinate system corresponding to the processing origin in the processing area of the laser processing device, and the origin coordinates of the screen frame are calculated and determined based on the current coordinates of the positioning component and the deviation distance between the positioning component and the processing component.

[0137] In addition, before determining the processable area of the screen frame, it is also necessary to obtain the size of the screen frame. Specifically, the processor, in response to the size setting instruction, obtains the size of the screen frame from the size setting instruction; or, obtains the first coordinate when the laser module emits light and aligns with the first boundary point of the screen frame and the second coordinate when the laser module emits light and aligns with the second boundary point of the screen frame, where the first boundary point and the second boundary point are the diagonals of the screen frame; determines the length and width of the screen frame based on the relative distance between the first coordinate and the second coordinate, and obtains the size of the screen frame.

[0138] To achieve better processing effects such as engraving and printing, taking the example that there should be a certain space reserved between the processed pattern and the edge of the screen frame and the screen frame is a rectangular screen frame, based on the positional relationship between the processing origin in the processing area of the laser processing device and the origin of the screen frame, and the size of the screen frame, the boundary point coordinates in the length direction of the screen frame and the boundary point coordinates in the width direction of the screen frame are determined; based on the boundary point coordinates in the length direction of the screen frame and the reserved length size, the first boundary point coordinates in the length direction of the processable area of the screen frame are determined, and based on the boundary point coordinates in the width direction of the screen frame and the reserved width size, the second boundary point coordinates in the width direction of the processable area of the screen frame are determined. Based on the first boundary point coordinates and the second boundary point coordinates, the boundary line of the processable area of the screen frame is displayed on the display interface.

[0139] The user moves one or more processed patterns to the processable area of the screen frame on the host computer software. The processor obtains the positions of the processed patterns in the processable area of the screen frame and controls the processing head to process the corresponding processed patterns at the corresponding positions.
