[0053] The position calibration method, position calibration device, electronic device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0054] The position calibration method can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0055] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets. It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer.

[0056] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0057] The position calibration method provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the position calibration method. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The position calibration method provided in this application embodiment is described below using an electronic device as the execution subject.

[0058] like Figure 1 As shown, the position calibration method includes steps 110, 120 and 130.

[0059] It should be noted that this position calibration method can be applied in production scenarios for position calibration.

[0060] The production scenarios include electronic equipment manufacturing, engineering machinery manufacturing, and general equipment manufacturing, and are especially suitable for manufacturing precision equipment such as mobile phones, headphones, and laptops for 3C products.

[0061] In precision equipment manufacturing scenarios, the screws used are all small-diameter screws. For tightening tiny screws, the position of the screw and the screw hole or the loading hole needs to be calibrated during the loading or tightening process.

[0062] Step 110: Attach the standard custom block 310 to the target hole. The standard custom block 310 has a center point on the surface away from the target hole, and the center point is located on the central axis of the target hole.

[0063] In this step, the standard custom block 310 may be a pre-configured auxiliary device for position calibration.

[0064] The X and Y directions of the standard custom block 310 are consistent with the machine tool when viewed from above.

[0065] The target hole can be a screw hole or a feeding hole on a feeding tray.

[0066] The center point can be a hollowed-out circular hole or a point marked at the center of the standard custom block 310.

[0067] For example, the diameter of the hollowed-out circular hole can be 0.01mm, 0.02mm or other smaller diameters, and this application does not limit it.

[0068] In some embodiments, the surface of the standard custom block 310 may be made based on a pressed color-changing material or a malleable material.

[0069] In this embodiment, the pressure-sensitive color-changing material can be a type of functional material whose color changes due to pressure variations.

[0070] Pressed color-changing materials can be a type of organic sensitive material.

[0071] Among them, the phenomenon of color change caused by various external or internal variables such as pressure in organic sensitive materials can be called pressure-induced color change.

[0072] Plastic materials are solid materials that can deform and retain their deformation under external force.

[0073] Plastic materials can be clay, modeling clay, and other materials that are malleable.

[0074] This application does not limit the specific type of malleable material used in actual implementation.

[0075] According to the position calibration method provided in the embodiments of this application, the position information can be effectively marked on the surface of the standard customized block 310 using pressed color-changing material or plastic material, providing data support for measuring offset and improving measurement accuracy.

[0076] The implementation of the standard custom block 310 will be explained from the perspectives of pressing color-changing materials and plastic materials.

[0077] Firstly, the surface of the standard custom block 310 is made based on pressed color-changing material.

[0078] like Figure 2 As shown, in some embodiments, the standard custom block 310 may include: a first component 210, a second component 220, and a cylinder 230.

[0079] In this embodiment, the first component 210 is a pressed color-changing material, and a center point is provided on the surface of the first component 210 away from the target hole.

[0080] The first component 210 can be a component whose surface is made of the pressed color-changing material.

[0081] In actual implementation, the pressed color-changing material can be sprayed alone or doped into the polymer and then sprayed onto the surface of the standard customization block 310.

[0082] The center point can be a circular dot marked on the surface of the pressed color-changing material or a hollow circular hole.

[0083] The cross section of the second component 220 is greater than that of the target hole, and the first component 210 is attached to the side of the second component 220 away from the target hole.

[0084] The second component 220 can be a cylinder or a cube.

[0085] The cross section of the second component 220 is greater than that of the target hole, which can better fix the standard customization block 310 and avoid the whole standard customization block 310 from falling into the target hole.

[0086] The cylinder 230 is arranged in the target hole, the diameter of the cylinder 230 matches the diameter of the target hole, and one side of the cylinder 230 is fixedly connected to the second component 220.

[0087] The cylinder 230 can be a component of the standard customization block 310.

[0088] The cylinder 230 can be a cylinder with external threads.

[0089] The cylinder 230 is arranged in the target hole, and the diameter of the cylinder 230 matches the diameter of the target hole.

[0090] The first component 210 is attached to the side of the second component 220 away from the target hole, the second component 220 is fixedly connected to one side of the cylinder 230, and the first component 210, the second component 220, the cylinder 230 and other connecting components can jointly constitute the standard customization block 310.

[0091] The central axes of the first component 210, the second component 220 and the cylinder 230 are coaxial.

[0092] According to the position calibration method provided in the embodiments of the present application, by setting the standard customization block 310 to include the first component 210, the second component 220 and the cylinder 230, using the first component 210 to collect the position information of the electric batch 240, and using the second component 220 and the cylinder 230 to stably place the standard customization block 310 in the target hole, a quantitative measuring device is provided for position calibration, manual probe measurement equipment is not needed, the operation is convenient, the data acquisition method is simple, and there is no spatial limitation.

[0093] Secondly, the surface of the standard custom block 310 is made from a malleable material.

[0094] like Figure 3 As shown, in some embodiments, the standard custom block 310 can be a columnar structure made of a malleable material. After attaching the standard custom block 310 to the target hole, the method may further include:

[0095] Press the standard custom block 310 in the direction of the target hole until an indentation 320 corresponding to the diameter of the target hole appears on the standard custom block 310;

[0096] The center of the 320mm indentation is determined as the center point.

[0097] In this embodiment, the standard custom block 310 can be a columnar structure made of a malleable material.

[0098] In actual implementation, the standard custom block 310 can also be a cube or cuboid made of malleable material.

[0099] The specific shape of the standard custom block 310 made of malleable material is not limited in this application.

[0100] The device used for the overall pressing standard custom block 310 can be a metal block.

[0101] The cross-sectional area of ​​the device used in the overall pressing standard custom block 310 can be greater than the cross-sectional surface area of ​​the aperture.

[0102] Understandably, during the pressing of the standard custom block 310, it is necessary to ensure that the surface of the standard custom block 310 is subjected to balanced force.

[0103] This application does not specifically limit the device used in the overall pressing standard custom block 310.

[0104] The aperture indentation 320 can be a mark produced by the deformation of a malleable material located inside the target hole when pressed.

[0105] It is understandable that the diameter of the 320mm indentation matches the diameter of the target hole.

[0106] The center point can be the center point determined by the center of the cross-section of the 320mm aperture indentation.

[0107] According to the position calibration method provided in the embodiments of the present application, the standard customization block 310 is made of plastic material, and the standard customization block 310 does not need to be set to the size of the target hole diameter in advance, and can be adapted to target holes of any size, and has wide application range and high flexibility; the standard customization block 310 is pressed as a whole by using the pressing device, so that the standard customization block 310 forms a hole diameter indentation 320 in the target hole, thereby determining the center point of the hole diameter indentation 320, and the position information of the measurement offset can be provided according to the obtained center point, and the measurement accuracy is improved.

[0108] In step 120, the bit head of the electric bit 240 is controlled to move to the surface of the standard customization block 310, and the bit head of the electric bit is controlled to extrude the surface, and the position point of the extrusion of the bit head and the surface is obtained; the central axis of the electric bit 240 is perpendicular to the plane where the surface is located;

[0109] In this step, the moving mode of the bit head of the electric bit 240 can be that the bit head of the electric bit 240 is controlled to move by a program in the automatic device.

[0110] The moving of the bit head of the electric bit 240 can be controlled so that the bit head of the electric bit 240 reaches above the adsorption position and the locking position.

[0111] The extrusion mode of the bit head can be that the bit head of the electric bit 240 is controlled to descend by a program.

[0112] The position point can be a point generated after the bit head of the electric bit 240 extrudes the surface of the standard customization block 310.

[0113] For example, in the case where the standard customization block 310 includes the first component 210, the second component 220 and the cylindrical body 230, the position point can be a point with color formed by extruding the color-changing material.

[0114] For another example, in the case where the standard customization block 310 is made of plastic material, the position point can be the midpoint of the indentation.

[0115] In the process of controlling the moving of the bit head of the electric bit 240, the central axis of the bit head of the electric bit 240 should be perpendicular to the plane where the standard customization block 310 is located.

[0116] In some embodiments, step 120 can further include:

[0117] The electric bit 240 is controlled to move to the bit head in contact with the surface;

[0118] In the case of contact, the electric bit 240 is controlled to press the surface in the direction of the target hole for a period of time, then the electric bit 240 is lifted, and the point corresponding to the indentation generated at the pressing position is determined as the position point.

[0119] In this embodiment, controlling the electric screwdriver 240 to move to the point where the bit contacts the surface can be done by adjusting the electric screwdriver 240 to descend after it reaches the adsorption position and the locking position, so that the bit of the electric screwdriver 240 contacts the pressed color-changing material on the surface of the standard custom block 310.

[0120] The target duration is the time taken for the bit of the electric screwdriver 240 to press against the surface of the standard custom block 310.

[0121] In actual execution, the target duration can be determined based on the specific duration for which the electric screwdriver 240 presses the surface of the standard custom block 310 to form a clear indentation. This application does not limit the specific time of the target duration.

[0122] The target duration can be determined based on user-defined values ​​or based on the surface material of the standard custom block 310. For example, the target duration can be set to 20 seconds or 30 seconds.

[0123] The location point can be the point where the indentation formed by the electric screwdriver 240 pressing the surface of the standard custom block 310 is located.

[0124] The following explanation uses the standard custom block 310 as an example of a malleable material to illustrate the execution process.

[0125] like Figure 4 As shown, a standard custom block 310 made of malleable material can be placed above the target hole. A metal object of a certain mass is used to press the standard custom block 310 so that the bottom of the standard custom block 310 can have an indentation of the hole diameter inside the target hole. The pressing object is removed, and the electric screwdriver 240 is adjusted to descend so that the electric screwdriver 240 presses the malleable material to form a position point on the surface of the malleable material.

[0126] According to the position calibration method provided in the embodiments of this application, by controlling the electric screwdriver 240 to descend, the screwdriver bit of the electric screwdriver 240 is moved to the surface of the standard customized block 310. When in contact, the electric screwdriver 240 is pressed towards the target hole for a target duration to form a position point. The determined position point can be used to determine the offset of the electric screwdriver 240 from the center point, providing data support for calibration, transforming qualitative judgment into quantitative measurement, and avoiding the differences in individual debugging.

[0127] Step 130: Based on the location point and center point, calibrate the position of the electric screwdriver 240.

[0128] In this step, the location point can be the point where the indentation formed by the electric screwdriver 240 pressing the surface of the standard custom block 310 is located.

[0129] The center point can be the center point set by the first component 210 of the standard custom block 310.

[0130] The center point can also be the center point of the aperture indentation 320 formed by pressing the plastic material.

[0131] The position of the electric wrench 240 can be adjusted to be within the range required by the target range requirement.

[0132] The inventor found in the research process that in the related art, after hand-eye calibration, the alignment degree of the electric wrench 240 and the loading position gap and the locking position screw hole is judged by naked eye observation at the adsorption position and the locking position, which has the problems of inaccurate judgment structure and different observation results by different detection personnel, in addition, the detection personnel needs to use a probe to observe during the observation process, which is dangerous and inconvenient to operate, and has spatial limitations.

[0133] In the present application, the standard customized block 310 is used to generate an indentation by contacting the electric wrench 240 with the surface of the standard customized block 310, and the position point and the center point are determined by the indentation, which effectively measures the offset information of the micro-size device, is simple to operate, and has high accuracy of measurement information.

[0134] According to the position calibration method provided in the embodiments of the present application, the standard customized block 310 with the center point is used to control the movement of the head of the electric wrench 240 to the surface of the standard customized block 310, and the head of the electric wrench 240 is pressed against the surface of the standard customized block 310 to generate a position point, and the information of the position point of the standard customized block 310 is obtained, which can convert the qualitative judgment offset information into quantitative measurement offset information; the detection personnel does not need to observe the offset information of the equipment by using a probe, which is simple and convenient to operate; by using the information of the position point and the center point, the position of the electric wrench 240 can be calibrated, the alignment degree of the electric wrench 240 and the target hole is improved, and the risk of locking failure is reduced.

[0135] In some embodiments, step 130 can further include:

[0136] determining the offset information of the position point relative to the center point;

[0137] in the case that the offset information is not within the target range, controlling the electric wrench 240 to move towards the center point and updating the position point;

[0138] in the case that the offset information is within the target range, stopping the calibration.

[0139] In this embodiment, the standard customized block 310 can be removed before determining the offset information of the position point relative to the center point, so as to measure the position information.

[0140] The offset information can be the offset amount of the position point relative to the center point in the X direction and the Y direction.

[0141] The target range can be a custom offset range based on actual needs (such as detection accuracy, installation accuracy, etc.).

[0142] This application does not limit the specific numerical values ​​of the target range.

[0143] The direction and magnitude of movement of the electric screwdriver 240 toward the center point can be determined based on the offset information.

[0144] Updating the position point can be achieved by re-measuring the position point after the electric screwdriver 240 has moved toward the center point, in order to update the position point information.

[0145] Understandably, the operation of measuring offset information can be performed repeatedly and calibration can be performed based on the offset information.

[0146] Calibration can be stopped if the measured offset information is within the target range.

[0147] The following describes the execution process using a standard custom block 310, which consists of a first component 210, a second component 220, a cylinder 230, and other connecting components, as an example.

[0148] like Figure 5 As shown, the standard customized block 310 is attached to the target hole. The electric screwdriver 240 is positioned above the adsorption and locking positions by the program. The electric screwdriver 240 is adjusted to descend vertically, so that the bit of the electric screwdriver 240 contacts the first component 210. With the bit of the electric screwdriver 240 in contact with the first component 210, the bit of the electric screwdriver 240 presses against the first component 210. After pressing for the target duration, a colored indentation, i.e., a position point, can be obtained on the first component 210. The standard customized block 310 is removed, and the offset information of the position point relative to the center point is measured. Then, based on the position information, the offset is manually or visually calibrated or applied. The adjusted electric screwdriver 240 is pressed down on the standard customized block 310 to obtain a new position point.
