Description

Technical Field

[0002] In the manufacturing process of laptops, due to the large number and variety of keyboard screws, robotic screw fastening is typically employed. Automatic screw fastening requires pre-extracting screw hole position information and storing it in a template file. This template file guides the robot to the screw hole positions during screw fastening. However, the robot's fastening positioning accuracy is affected by the offset distance between the screw hole and the center of the positioning camera's field of view. A larger offset results in a greater positioning error, leading to low accuracy when the robot uses the template file for screw hole fastening. Therefore, how to automatically correct the screw hole position template file and improve the fastening positioning accuracy has become a pressing technical problem. Summary of the Invention

[0040] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0041] Because the positioning accuracy of current robot screw fastening is affected by the offset distance between the screw hole and the center of the positioning camera's field of view, the positioning accuracy of the robot when using a template file for screw fastening is relatively low. Therefore, to automatically correct the template file for screw hole positions and improve the positioning accuracy, this application provides a data correction method, apparatus, electronic device, and storage medium. The electronic device provided in this application can be a mobile phone, computer, tablet computer, or similar device.

[0042] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings.

[0043] Figure 1 This illustration shows a schematic diagram of an implementation flow of the data correction method provided in an embodiment of this application, such as... Figure 1 As shown, the method includes:

[0044] S101, when an abnormality is detected in the locking device, a template file to be corrected is obtained, wherein the template file to be corrected includes the first position information of multiple screw holes of the target device.

[0045] In this disclosure, a screw-fastening device refers to a device that fastens screws into the screw holes of a target device. For example, a screw-fastening device may include a robot that fastens screws. Abnormalities in the screw-fastening device include collisions or misalignment of the device's mounting bracket. The target device may be an electronic device such as a laptop or mobile phone.

[0046] In this disclosure, the template file includes signals such as the type and location of the screw holes in the target device and the corresponding screw model. The template file to be corrected includes the first position information of multiple screw holes on the target device. The first position information includes the position coordinates of the screw holes.

[0047] In this disclosure, calibration function options can also be pre-set via calibration software. These options are used to initiate calibration operations on the template file. If the user enables the calibration function options in the calibration software, the template file to be calibrated can be obtained and calibrated when an anomaly is detected in the locking device. If the user does not enable the calibration function options in the calibration software, the template file to be calibrated may not be calibrated after an anomaly is detected in the locking device.

[0048] S102, based on the locking device, obtain the second position information of each screw hole of the target device.

[0049] In this disclosure, after detecting an abnormality in the fastening device, the fastening device can be controlled to mark the actual position coordinates of each screw hole on the target device as the second position information of the screw holes.

[0050] In one possible implementation, obtaining the second position information of each screw hole of the target device based on the locking device may include steps A1-A2:

[0051] Step A1: Control the fastening device to collect image information of each screw hole of the target device according to the fastening sequence.

[0052] In this disclosure, the operating trajectory of the locking device can be preset, for example, operating in a sequence from left to right and from top to bottom on the surface of the target device. The operating trajectory can be used as the locking sequence.

[0053] In this disclosure, the fastening device can be controlled to acquire images of each screw hole of the target device in the fastening sequence, or images of all screw holes of the target device can be acquired.

[0054] Step A2: Determine the second position information of each screw hole of the target device based on the image information.

[0055] In this disclosure, a contour detection algorithm can be used to extract the screw hole contours of each screw hole included in the image information. Then, the geometric center coordinates of the screw hole contours of each screw hole are calculated, and the geometric center coordinates of the screw hole contours are used as the second position information of the screw holes.

[0056] S103, determine the screw hole offset information based on the first position information and the second position information.

[0057] In this disclosure, the positional offset between the first position information and the second position information of each screw hole of the target device can be calculated as screw hole offset information.

[0058] In one possible implementation, determining the screw hole offset information based on the first position information and the second position information may include steps B1-B3:

[0059] Step B1: Obtain the second position information of the screw holes corresponding to a preset number of target devices, and obtain a preset number of sets of second position information.

[0060] In this disclosure, the preset quantity can be set to 4 or 5, etc.

[0061] Step B2: Determine the position offset between each group of second position information and the first position information.

[0062] In this disclosure, a fastening device can be used to fasten the screw holes of multiple target devices, thereby obtaining the positional offset between the actual position coordinates of each screw hole on each target device and the position coordinates recorded in the template file to be calibrated. The positional offset may include lateral offset and longitudinal offset.

[0063] For example, if the fastening device collects the second position information of the screw holes of 5 target devices, and determines the positional offset between each set of second position information and the first position information, the lateral offset and longitudinal offset corresponding to each target device can be obtained:

[0064] The offsets are (x1_offset, y1_offset), (x2_offset, y2_offset), (x3_offset, y3_offset), (x4_offset, y4_offset), and (x5_offset, y5_offset). Here, x1_offset, x2_offset, x3_offset, x4_offset, and x5_offset represent the lateral offsets of the screw hole positions corresponding to each target device, and y1_offset, y2_offset, y3_offset, y4_offset, and y5_offset represent the longitudinal offsets of the screw hole positions corresponding to each target device.

[0065] Step B3: Determine the variance corresponding to the position offset of each group, as the screw hole offset information.

[0066] In this disclosure, the variance corresponding to each group of position offsets can be determined using the following formula:

[0067]

[0068] Among them, S 2 Let x represent the variance corresponding to the position offset, n represent the number of target devices, m represent the average position offset of a preset number of groups, and x represent the variance.i This represents the position offset of the i-th group.

[0069] In this disclosure, the variances corresponding to the lateral offsets of each group and the longitudinal offsets of each group can also be calculated separately.

[0070] S104, Based on the screw hole offset information, correct the template file to be corrected.

[0071] In this disclosure, the position information of the corresponding screw holes in the template file to be corrected can be adjusted according to the screw hole offset information to achieve automatic correction of the template file.

[0072] The data correction method provided in this disclosure involves obtaining a template file to be corrected when an anomaly is detected in the fastening device. This template file includes first position information of multiple screw holes on the target device. Second position information of each screw hole on the target device is obtained based on the fastening device. Screw hole offset information is determined based on the first and second position information. The template file to be corrected is then corrected based on the screw hole offset information. When an anomaly occurs in the fastening device, the position information of each screw hole on the target device is determined using the fastening device. The screw hole offset information is then used to determine the screw hole offset information, thus achieving automatic correction of the template file. This automatic correction of the template file also improves the fastening positioning accuracy of using the template file for screw hole fastening.

[0073] In one possible implementation, correcting the template file to be corrected based on the screw hole offset information may include steps C1-C2:

[0074] Step C1: Determine whether the variance is less than a preset variance threshold.

[0075] In this disclosure, it is possible to determine whether the variances corresponding to each group of horizontal offsets and each group of vertical offsets are both less than a preset variance threshold. The preset variance threshold can be set according to actual application requirements.

[0076] Step C2, if yes, correct the template file to be corrected according to the variance.

[0077] If the variances corresponding to the lateral offsets of each group and the longitudinal offsets of each group are both less than the preset variance threshold, it indicates that the carrier position of the locking device is stable and suitable for correction, and the template file can be corrected.

[0078] Specifically, for each screw hole of the target device in the template file, the sum of the lateral position coordinate of the screw hole recorded in the template file and the corresponding lateral offset can be calculated as the new lateral position coordinate. Similarly, the sum of the longitudinal position coordinate of the screw hole recorded in the template file and the corresponding longitudinal offset can be calculated as the new longitudinal position coordinate. The new lateral and longitudinal position coordinates for each screw hole are then updated in the template file to obtain the corrected template file.

[0079] In this disclosure, if the variances corresponding to the lateral offsets of each group and the longitudinal offsets of each group are not less than a preset variance threshold, it indicates that the carrier position of the fastening device is unstable, which will affect the screw fastening operation and is not conducive to the correction of the template file.

[0080] Figure 2 This illustration shows a schematic diagram of screw hole position correction provided in an embodiment of this application, as shown below. Figure 2 As shown, the positional offset between the actual position of the screw hole and the screw hole position 210 recorded in the template file is collected by the fastening device. Based on the positional offset, the screw hole position 210 recorded in the template file is corrected to obtain the corrected screw hole position 220. The corrected screw hole position 220 is then updated to the template file, thus realizing the correction of the template file.

[0081] Using the data correction method provided in this disclosure, when the fastening device malfunctions, the position information of each screw hole of the target device is determined by the fastening device. The screw hole offset information is determined by using the position information and the position information in the template file to be corrected. The template file is automatically corrected by the screw hole offset information. The fastening positioning accuracy of the screw hole fastening using the template file is also improved by automatically correcting the template file.

[0082] Based on the same inventive concept, and according to the data correction method provided in the above embodiments of this disclosure, another embodiment of this disclosure also provides a data correction device, the structural schematic diagram of which is shown below. Figure 3 As shown, it specifically includes:

[0083] The first information acquisition module 301 is used to acquire a template file to be corrected when an abnormality is detected in the locking device. The template file to be corrected includes the first position information of multiple screw holes of the target device.

[0084] The second information acquisition module 302 is used to acquire the second position information of each screw hole of the target device based on the locking device;

[0085] The offset information determination module 303 is used to determine the screw hole offset information based on the first position information and the second position information;

[0086] The correction module 304 is used to correct the template file to be corrected based on the screw hole offset information.

[0087] Using the data correction device provided in this disclosure, when an anomaly is detected in the fastening device, a template file to be corrected is acquired. The template file includes first position information of multiple screw holes on the target device. Second position information of each screw hole on the target device is acquired based on the fastening device. Screw hole offset information is determined based on the first and second position information. The template file to be corrected is then corrected based on the screw hole offset information. When an anomaly occurs in the fastening device, the position information of each screw hole on the target device is determined using the fastening device. The screw hole offset information is then used to determine the screw hole offset information, thus achieving automatic correction of the template file. This automatic correction of the template file also improves the fastening positioning accuracy of using the template file for screw hole fastening.

[0088] In one embodiment, the second information acquisition module 302 is specifically used to control the fastening device to acquire image information of each screw hole of the target device in fastening sequence; and to determine the second position information of each screw hole of the target device based on the image information.

[0089] In one possible implementation, the offset information determination module 303 is specifically used to obtain the second position information of screw holes corresponding to a preset number of target devices, to obtain a preset number of sets of second position information; determine the position offset between each set of second position information and the first position information; and determine the variance corresponding to each set of position offsets as screw hole offset information.

[0090] In one possible implementation, the correction module 304 is specifically used to determine whether the variance is less than a preset variance threshold; if so, to correct the template file to be corrected based on the variance.

[0091] Using the data correction device provided in this disclosure, when the fastening device malfunctions, the position information of each screw hole of the target device is determined by the fastening device. The screw hole offset information is determined by using the position information and the position information in the template file to be corrected. The automatic correction of the template file is achieved by using the screw hole offset information. The automatic correction of the template file also improves the fastening positioning accuracy of using the template file for screw hole fastening.
