[0055] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0061] Figure 1 A flowchart of a method for confirming accuracy provided in an embodiment of the present invention is shown below. Figure 1 As shown, the method includes:

[0062] Step 101: The laser equipment laser-etches the first pattern on the calibration plate based on the acquired first laser information.

[0063] In this embodiment of the invention, the laser device acquires first laser information, which is typically information set by the operator. The first laser information includes at least one of the following: first shape graphic information, data code information, and target information. The first graphic includes at least one of multiple first shape graphics, multiple targets, and data codes. The data code includes a QR code. The first shape graphic includes shapes such as circles, crosses, or squares; however, since a circular first shape provides better gripping performance for the measuring device, the first shape graphic is usually circular. The first shape graphic information includes at least one of the following: the shape of the first shape graphic, the number of shapes, the spacing between shapes, and the first theoretical coordinates of the multiple first shape graphics.

[0064] The laser marking equipment includes a laser marking device, which comprises a galvanometer and an integrated circuit (IC) substrate laser marking device. The galvanometer emits light from its center. The IC substrate laser marking device performs targetless positioning laser marking on a calibration board based on first laser information, marking at least one of multiple first shape graphics, multiple targets, and data codes. The IC substrate laser marking device includes an X-out device, which is the marking process for NG units in the substrate processing steps. The operator uses trans software to convert the format of the first laser information from AutoCAD's DXF format to PRG format, and then imports the PRG format first laser information into the X-out device. To ensure the laser marks are clearly visible, the calibration board is typically a black calibration board.

[0065] Figure 2 A schematic diagram of a calibration plate after the first laser treatment is provided in an embodiment of the present invention, as shown below. Figure 2As shown, the dashed box represents the galvanometer area. The calibration plate includes one QR code, 5*8 ​​hollow circles with a diameter of 2 mm, and 4 solid circles with a diameter of 2 mm. In the 5*8 hollow circles with a diameter of 2 mm, the distance between two adjacent hollow circles is 40 mm, and the processing area is 320 mm * 200 mm. When filling the interior of the solid circles, line segments with a spacing of 40 micrometers (µm) can be filled.

[0066] like Figure 2 As shown, the first graphic includes multiple first shape graphics, a data code, and multiple targets. The multiple first shape graphics refer to 5*8 hollow circles with a diameter of 2mm, the data code refers to a QR code, and the multiple targets refer to 4 solid circles with a diameter of 2mm.

[0067] This application does not limit the shape of the first shape graphic, data code, or target.

[0068] Step 201: The measuring device acquires the first graphic information of the first graphic based on the first image of the first graphic, and generates the galvanometer laser accuracy according to the first graphic information and the first laser information.

[0069] In this embodiment of the invention, the operator imports the first laser information into the measuring device; the measuring device can scan the calibration plate to generate a first image, and generate first graphic information based on the first image. The first graphic information includes at least one of the following: graphic shape, number of graphics, graphic spacing, and first actual coordinates of multiple first-shape graphics. The measuring device includes a two-dimensional detection device.

[0070] Galvanometer laser precision can also be called machine installation precision. Currently, the required galvanometer laser precision is usually less than or equal to 20µm. After the equipment is installed, the galvanometer laser precision can be used to confirm whether the machine's precision meets the requirements. If the galvanometer laser precision is less than or equal to 20µm, it indicates that the machine installation precision meets the requirements.

[0071] Step 102: The laser equipment acquires the second laser information and laser-prints the second pattern on the calibration plate based on the acquired second laser information.

[0072] In this embodiment of the invention, the laser equipment acquires second laser information, which is typically set by the operator. The operator processes the first laser information, using trans software to set the Pce tool, scanning position, border position, target position, etc., to generate the second laser information. Here, the Pce tool refers to the second graphic to be laser-etched; the scanning position is the specific location of the data code on the calibration plate; the border position is the border of the calibration plate; during processing, a robotic arm automatically feeds the material, and a feeding rod aligns the calibration plate, with the alignment length and width determined by the border position; the target position refers to the target's coordinate information, allowing the camera to locate itself using the target position to ensure no laser misalignment. Figure 3 This is a schematic diagram of a graphics processing page provided in an embodiment of the present invention. Figure 3 The page shown is where the user sets the second laser information using the trans software, such as... Figure 3 As shown, users can set the position of the target, the laser pattern, the position of the outer contour of the calibration board, the position of the scanning position, the position of the clear code position, the position of the outer rectangle of a single unit, and the position of the gold dot, etc.

[0073] The second laser information includes at least one of the following: data code position information, third laser information, and sheet border position information. The data code position information includes the position range of the data code. The sheet border position information includes the position information of the entire sheet's outer contour. The third laser information includes target information and second shape graphic information. The target information includes the target position information of multiple targets. The second graphic includes multiple second shape graphics. The second shape graphics include shapes such as circles, crosses, or squares. The second shape graphic information includes at least one of the following: the shape of the second shape graphic, the number of shapes, the spacing between shapes, and the second theoretical coordinates of the multiple second shape graphics.

[0074] The laser marking equipment includes a camera and a laser marking device, which in turn includes a galvanometer and an IC substrate laser marking device. The camera includes a line scan camera. Depending on the model of the galvanometer, its deflection range varies; for example, the deflection range of the galvanometer is 140*140mm. In automatic processing, the galvanometer deflects, and the IC substrate laser marking device, using the camera, laser-marks multiple second-shape graphics on a calibration board based on the second laser information. The automatic processing method is the substrate laser marking method, where the laser equipment performs at least one of the following steps: barcode scanning and identification, target positioning, automatic loading and unloading, and material handling. During the laser marking process, the IC substrate laser marking device uses the camera to position the target on the calibration board to ensure the correct positioning of the multiple laser-marked second-shape graphics.

[0075] If the user settings are in Figure 2 The calibration plate shown has 4*8 second-shape patterns laser-etched on it. Figure 4This is a schematic diagram of a calibration plate image after a second laser treatment, provided in an embodiment of the present invention. Figure 4 The calibration plate image shown corresponds to the calibration plate and Figure 1 The calibration plates shown are the same calibration plate. For example... Figure 4 As shown, the calibration board includes a QR code, 5*8 ​​hollow circles with a diameter of 2mm, 5 solid circles with a diameter of 2mm, and 4*8 solid circles with a diameter of 1mm. The first row of 8 hollow circles with a diameter of 2mm does not include any solid circles with a diameter of 1mm. The three targets within the white box are the targets captured by the IC carrier board laser marking device through a camera. Among the 5*8 hollow circles with a diameter of 2mm, the theoretical center coordinates of the 4*8 hollow circles with a diameter of 2mm are the same as the theoretical center coordinates of the corresponding 4*8 solid circles with a diameter of 1mm. These hollow circles with a diameter of 2mm and solid circles with a diameter of 1mm are defined as a concentric circle group. Figure 5 A schematic diagram of concentric circles provided in an embodiment of the present invention, as shown below. Figure 5 As shown, Figure 5 The diagram shown is theoretically... Figure 4 The enlarged image of a set of concentric circles shown shows that the theoretical coordinates of the center of the hollow circle with a diameter of 2mm are the same as the theoretical coordinates of the center of the corresponding solid circle with a diameter of 1mm.

[0076] like Figure 4 As shown, the second graphic includes multiple second-shape graphics. The second-shape graphics refer to 4*8 solid circles with a diameter of 1mm each. The scanning range of the line scan camera is 345*250mm, and the processing range is 320mm*200mm. The scanning range is larger than the processing range, and the camera's accuracy confirmation range covers the entire table surface, avoiding the situation where only local accuracy can be confirmed during laser processing of the calibration board target. The IC carrier board laser marking equipment, through the camera, can laser-mark 1mm diameter solid circles concentric with each 2mm diameter hollow circle on the calibration board.

[0077] Step 202: The measuring device acquires the second graphic information of the second graphic based on the second image of the second graphic, and generates the target laser accuracy according to the second graphic information and the first graphic information.

[0078] In this embodiment of the invention, the measuring device can scan the calibration plate again to generate a second image, and generate second graphic information based on the second image.

[0079] If the user does not have measuring equipment, they can visually determine whether there is a deviation between the center of a 2mm diameter hollow circle and the center of a 1mm diameter solid circle within that hollow circle. Since the user's observation precision is typically 70µm, if the user can visually determine that there is a deviation between the center of the 2mm diameter hollow circle and the center of the 1mm diameter solid circle within that hollow circle, then the center deviation is greater than 70µm.

[0080] Laser target marking accuracy, also known as line scan accuracy, refers to the processing precision of the camera after the laser marking device uses a camera for target positioning. Currently, the required processing precision is typically less than or equal to 50µm. If, after visually inspecting the calibration plate following the second laser marking, the user finds a deviation between the center of a 2mm diameter hollow circle and the center of a 1mm diameter solid circle within that hollow circle, it indicates that the camera's laser target marking accuracy does not meet the requirements. After determining that the camera's laser target marking accuracy is insufficient, the camera needs to undergo a step to determine the overall deviation value to ensure that the camera's target target marking accuracy is less than or equal to 50µm.

[0081] In this embodiment of the invention, step 201 can be executed after step 101. Optionally, step 201 can be executed before step 102, after step 102, after step 202, or synchronously with step 202. In this embodiment of the invention, the execution order of step 201 is not limited.

[0082] This invention provides a method for confirming accuracy. A laser device laser-etches a first pattern on a calibration plate based on acquired first laser information. A measuring device acquires the first pattern information and generates galvanometer laser accuracy based on the first pattern information and the first laser information. The laser device acquires second laser information and laser-etches a second pattern on the calibration plate based on the second laser information. The measuring device acquires the second pattern information and generates target-grabbing laser accuracy based on the second pattern information and the first pattern information. The laser device includes a laser marking device or a laser marking device and a camera. The laser accuracy includes galvanometer laser accuracy and target-grabbing laser accuracy. The laser marking device can directly laser-etch patterns on the calibration plate; to ensure accurate positioning during laser-etching, the laser marking device can also use a camera to grasp and position the target before laser-etching. Thus, the measuring device confirms the galvanometer laser accuracy of the laser device based on the first pattern laser-etched by the laser marking device; and confirms the target-grabbing laser accuracy of the camera based on the second pattern laser-etched by the laser marking device using the camera, allowing the user to confirm the laser accuracy of the laser device.

[0083] In one possible implementation, the first graphic includes multiple first shape graphics, the first laser information includes the first theoretical coordinates of the multiple first shape graphics, and the first graphic information includes the first actual coordinates of the multiple first shape graphics; step 201 may specifically include: the measuring device calculates the galvanometer laser accuracy based on the first theoretical coordinates and the first actual coordinates of the multiple first shape graphics.

[0084] In this embodiment of the invention, after calculating the galvanometer laser accuracy, the measuring device can also generate a calculation page based on the first theoretical coordinates and first actual coordinates of multiple first shape graphics and the galvanometer laser accuracy. The calculation page includes the calculated galvanometer laser accuracy, multiple first shape theoretical graphics, and multiple first shape actual graphics.

[0085] Figure 6 This is a schematic diagram of a page provided in an embodiment of the present invention. Figure 6 The page shown is a portion of the calculation page, such as... Figure 6 As shown, the first shape is a circle. The white circle A is the theoretical first shape generated by the measuring device based on the first shape information. The diagonal circle B and the square circle C are the actual first shape generated by the measuring device based on the first shape information captured by the laser markings of multiple first shape patterns on the calibration plate. The square circle C is a special processing measure taken because the difference between the actual and theoretical coordinates is too large, so that the user can more clearly understand the difference between the actual and theoretical coordinates of the laser pattern on the calibration plate.

[0086] In one possible implementation, the first graphic includes a data code, the second laser information includes data code position information and third laser information; step 102 specifically includes:

[0087] Step 1021: The laser equipment identifies the data code on the calibration board based on the data code position information and generates identification information.

[0088] In this embodiment of the invention, the data code includes a QR code, and the QR code includes a Data Matrix (DM) code. The laser device includes a camera and a laser marking device. The laser marking device uses the camera to identify the data code on the calibration plate based on the data code position information, and generates identification information. The identification information may include at least one of numbers, letters, and symbols.

[0089] Figure 7 A schematic diagram of a DM code provided in an embodiment of the present invention, as shown below. Figure 7 As shown, the machine's recognition rate is lower for the outer contour compared to the solid part. Figure 7 The DM code shown is a DM code with internal line filling. The camera can capture it. Figure 2 The image shown is of the calibration plate after the first laser treatment. The calibration plate image includes... Figure 7 The DM code shown is sent to the laser marking device after the first laser correction plate image. The laser marking device identifies the DM code based on the first laser correction plate image and generates identification information.

[0090] Step 1022: The laser equipment determines whether the identification information is the same as the obtained part number input information. If yes, proceed to step 1023; otherwise, end the process.

[0091] In this embodiment of the invention, the laser marking device acquires the part number input information from the part number input box; and determines whether the identification information is the same as the part number input information. When determining whether the identification information is the same as the part number input information, if both the identification information and the part number input information include letters, the laser marking device does not distinguish between uppercase and lowercase letters.

[0092] Step 1023: The laser equipment laser-etches the second pattern on the calibration plate according to the third laser information.

[0093] In this embodiment of the invention, the first graphic includes multiple targets, and the third laser information includes target information and second shape graphic information; step 1023 includes: the laser device acquiring a calibration plate image of the calibration plate, the calibration plate image including multiple targets; the laser device associating the target information with the multiple targets; the laser device laser-etching the second graphic on the calibration plate according to the second shape graphic information through the multiple targets corresponding to the target information.

[0094] The laser marking equipment includes a laser marking device and a camera. The laser marking device includes an IC substrate laser marking device. The target information includes the target position information of multiple targets. The camera acquires images of the calibration board. Multiple target position information is mapped to multiple targets using the calibration board image. Each target corresponds to one target position information, and the number of targets corresponding to each target position information should be greater than or equal to a corresponding threshold. The corresponding threshold can be set by the user and is less than or equal to the total number of targets in the calibration board. Figure 4 As shown, the three targets within the white box correspond to the target position information. The camera can determine the theoretical coordinates of the second shape to be laser-etched on the calibration plate by associating multiple target position information with multiple targets, enabling the laser marking device to laser-etch the second shape according to the specific position determined by the camera.

[0095] In one possible implementation, the second laser information includes the third laser information, and step 102 specifically includes:

[0096] Step 1024: The laser device determines whether the number of targets acquired is greater than or equal to the target threshold. If yes, proceed to step 1025; otherwise, end the process.

[0097] In this embodiment of the invention, before step 1024, the method further includes: the laser marking device uses a camera to capture the target on the calibration plate and generates the number of captured targets.

[0098] The laser marking device acquires an image of the calibration plate using a camera; it then identifies targets based on the image; the number of identified targets is counted, generating a target count. The laser marking device can define the identified targets as the first target. The target threshold can be set by the user, and the target threshold can be less than or equal to the total number of targets on the calibration plate. Figure 4 As shown, the laser marking device is from Figure 4 The calibration plate image shown contains three targets. When the target threshold is 3, the laser marking device can determine that the number of targets captured is equal to the target threshold and proceed to step 1025.

[0099] Step 1025: The laser equipment laser-etches the second pattern on the calibration plate according to the third laser information.

[0100] In this embodiment of the invention, step 1025 can refer to step 1023 described above.
