[0029] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present disclosure and its application or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present disclosure thorough and complete and to fully express the scope of the present disclosure to those skilled in the art. It should be noted that unless otherwise specifically stated, the relative arrangement of the components and steps, the composition of the materials, the numerical expressions and the numerical values ​​set forth in these embodiments should be interpreted as being merely exemplary and not as limiting.

[0030] The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different parts. The words "include" or "comprise" and similar words mean that the elements before the word include the elements listed after the word, and do not exclude the possibility of including other elements. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0031] In the present disclosure, when a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other device without an intermediate device, or may not be directly connected to the other device but have an intermediate device.

[0032] All terms (including technical terms or scientific terms) used in the present disclosure have the same meanings as those understood by ordinary technicians in the field to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0034] In related technologies, the speed of manual measurement is increasingly unable to meet the growing measurement needs, resulting in low efficiency of fixture measurement. For example, the current average measurement speed is 5h / pallet (hours / pallet). However, facing the number of pallets of 100 sets / wire and the relatively small number of measurement personnel at each base, the measurement efficiency cannot meet the measurement needs, and it will also bring errors caused by different manual inspection methods.

[0035] In the measurement method of related technology, it is necessary to specially arrange to stop production and line, and use handheld three-coordinate tools to perform manual accuracy review. This solution requires professional personnel to perform the operation, which has high requirements, and the measurement personnel's techniques will also affect the error.

[0036] In view of this, an embodiment of the present disclosure provides a precision measurement device to improve the efficiency of precision measurement.

[0037] Figure 1 is a structural block diagram showing an accuracy measurement device according to some embodiments of the present disclosure.

[0038] like Figure 1As shown, the accuracy measurement device includes: a data detection device 110, a controller 120 and an alarm device 130. The controller 120 is electrically connected to the data detection device 110, and the alarm device 130 is electrically connected to the controller 120.

[0039] The data detection device 110 is configured to detect the detected object to obtain detection data and transmit the detection data to the controller 120. The data detection device 110 includes at least one of a position detection device and a distance detection device. Therefore, the detection data includes at least one of position data and distance data.

[0040] For example, the data detection device is a position detection device, which is configured to detect the position data of the detected object and transmit the position data to the controller. For example, the position detection device is configured to detect the position data (e.g., the coordinates of a certain point or certain points on the reference block) of the pallet (also referred to as a positioning pin), and transmit the position data to the controller. Here, the data detection device is a position detection device, and the detection data is position data.

[0041] For another example, the data detection device is a distance detection device, which is configured to detect the distance data from the distance detection device to the detected object, and transmit the distance data to the controller. For example, the distance detection device is configured to detect the distance data from the distance detection device to the support surface of the support block of the pallet (for example, the distance data from the distance detection device to a certain point or certain points on the support surface of the support block of the pallet), and transmit the distance data to the controller. Here, the data detection device is a distance detection device, and the detection data is distance data.

[0042] For another example, the data detection device includes a position detection device and a distance detection device, and the detection data includes position data and distance data.

[0043] The controller is configured to calculate an offset value between the detection data and the reference data, compare the offset value with a threshold value, and output alarm information when the offset value is greater than the threshold value.

[0044] The alarm device 130 is configured to give an alarm after receiving the alarm information. For example, the alarm device may include at least one of a sound alarm, an alarm indicator light, and a display. The alarm device may give an alarm by sound, light, or alarm information display.

[0045] So far, an accuracy measurement device according to some embodiments of the present disclosure is provided. The accuracy measurement device includes: a data detection device, the data detection device includes at least one of a position detection device and a distance detection device; a controller electrically connected to the data detection device; and an alarm device electrically connected to the controller. This can realize automatic detection of accuracy, thereby improving the efficiency of accuracy measurement.

[0046] In addition, in addition to improving measurement efficiency, the precision measurement device also improves measurement accuracy, saves manpower, and reduces the manpower requirements of measurement tasks.

[0047] Figure 2 is a structural block diagram showing an accuracy measurement device according to some other embodiments of the present disclosure.

[0048] like Figure 2 As shown, the accuracy measurement device includes: a data detection device 110, a controller 120 and an alarm device 130. The data detection device 110 includes a position detection device 111 and a distance detection device 112. The position detection device 111 and the distance detection device 112 are electrically connected to the controller 120 respectively.

[0049] The position detection device 111 is configured to detect position data of the detected object and transmit the position data to the controller 120. For example, the position detection device is configured to detect position data of a reference block of a pallet and transmit the position data to the controller.

[0050] For example, the position detection device includes a two-dimensional camera (2D camera). The 2D camera can fit the XY coordinates of the vertices of the reference block. By using the 2D camera as the position detection device, the accuracy measurement of the reference block of the pallet can be achieved, which can improve the efficiency of the accuracy measurement and reduce the error.

[0051] Figure 3 is a schematic diagram showing the accuracy measurement of a reference block according to some embodiments of the present disclosure. Figure 3 3 shows a pallet 300, which includes a reference block 310 and a support block 320. For example, the reference block is used as a detected object. Figure 3 , the coordinates (X0, Y0) of a certain point P0 of the reference block 310' at the reference position (as position reference data) and the coordinates (X1, Y1) of a point P1 of the reference block 310 at the actual position corresponding to the point P0 (as detected position data) are shown.

[0052] The controller 120 is configured to calculate a first offset value S1 between the detected position data and the position reference data, and compare the first offset value S1 with a first threshold value σ1, and output a first alarm message when the first offset value is greater than the first threshold value. The alarm device 130 is configured to give an alarm after receiving the first alarm message. The first threshold value can be set according to actual conditions.

[0053] In the above embodiment, P0 is the reference point of the reference block, and P1 is the measured point of the reference block. If the coordinates of the two points are known, the offset value of the two points can be obtained. The offset value is the offset accuracy of the reference block fixed point. A reasonable alarm threshold is set. When the offset value is greater than the threshold, the system alarms. In this way, automatic detection of accuracy is achieved, and the efficiency and accuracy of detection are improved.

[0054] The distance detection device 112 is configured to detect the distance data from the distance detection device to the detected object and transmit the distance data to the controller. For example, the distance detection device is configured to detect the distance data from the distance detection device to the support surface of the support block of the tray and transmit the distance data to the controller.

[0055] For example, the distance detection device includes a three-dimensional profiler (3D profiler) or a rangefinder. By using the three-dimensional profiler or the rangefinder as the distance detection device, the precision measurement of the support surface of the support block of the pallet can be achieved, which can improve the efficiency of the precision measurement and reduce the error.

[0056] Figure 4A is a schematic diagram illustrating support surface accuracy measurement according to some embodiments of the present disclosure. Figure 4B is a side view showing the support surface accuracy measurement according to some embodiments of the present disclosure. Figure 4A and Figure 4B 3 shows a pallet 300, which includes a reference block 310 and a support block 320. For example, the support block is used as an object to be detected. Figure 4A and Figure 4B The figure shows the reference value Z0 of multiple points on the supporting surface of the supporting block (i.e. the reference value of the distance data from the distance detection device to the supporting surface of the supporting block, used as the distance reference data), and the actual measured values ​​Z1, Z2, Z3, Z4... (i.e. the actual values ​​of the distance data from the distance detection device to the supporting surface of the supporting block, used as the detected distance data) of multiple points on the supporting surface of the supporting block.

[0057] The controller 120 is configured to calculate a second offset value S2 between the detected distance data and the distance reference data, and compare the second offset value S2 with a second threshold value σ2, and output a second alarm message when the second offset value is greater than the second threshold value. The alarm device 130 is configured to give an alarm after receiving the second alarm message. The second threshold value can be set according to actual conditions.

[0058] For example, a robot is provided on the equipment, and the robot can carry a three-dimensional profiler or a rangefinder for measurement, so as to obtain the Z value data of a specified point on the support block. Several points can be set on one surface of the support block to evaluate its accuracy. Z0 is the reference value of the reference point of the support surface, and Z1, Z2, Z3, Z4... are the measured values ​​of the actual points of the support surface. The Z values ​​of the reference point and the actual point corresponding to the reference point are known, and the offset value of the two points can be obtained. The offset value can evaluate the offset accuracy of the support surface, and a reasonable alarm threshold is set. When the offset value is greater than the threshold, the system alarms. In this way, automatic detection of accuracy is achieved, and the efficiency and accuracy of detection are improved.

[0059] The above-mentioned precision measuring device realizes the measurement of the precision of the pallet at the workstation and the testing and research in the digital factory environment, so as to achieve automatic and efficient online detection, which can reduce the downtime and downtime cost.

[0065] like FIG. 5A to FIG. 5D As shown, the precision measuring device may further include a second straight module 521. The second straight module 521 is connected to the first straight module 511. The second straight module 521 extends along a second direction Y. The second direction Y intersects with the first direction Z. The second straight module 521 may run in the second direction, so that the positions of the position detection device and the distance detection device in the second direction may be adjusted.

[0066] like FIG. 5A to FIG. 5D As shown, the precision measuring device may further include a second motor 522. The second motor 522 is connected to the second straight-moving module 521. The second motor 522 is configured to drive the second straight-moving module 521 to run in the second direction.

[0067] In the above embodiment, by providing the second straight-moving module and the second motor, it is possible to facilitate the movement of the data detection device (eg, the position detection device and the distance detection device) in the second direction, thereby facilitating the implementation of the accuracy detection.

[0068] In some embodiments, the second direction Y is perpendicular to the first direction Z. This facilitates the movement of the data detection device in mutually perpendicular directions, thereby facilitating the implementation of precision detection.

[0069] like FIG. 5A to FIG. 5DAs shown, the precision measuring device may further include a third straight module 531. The third straight module 531 is connected to the second straight module 521. The third straight module 531 extends along a third direction X. The third direction X intersects with the first direction Z, and the third direction X intersects with the second direction Y. The third straight module 531 may run in the third direction, so that the positions of the position detection device and the distance detection device in the third direction may be adjusted.

[0070] like FIG. 5A to FIG. 5D As shown, the precision measuring device may further include a third motor 532. The third motor 532 is connected to the third straight-moving module 531. The third motor 532 is configured to drive the third straight-moving module 531 to move in a third direction.

[0081] It should be noted that the cylinder 570 and the base 580 may not be provided in the precision measuring device of the embodiment of the present disclosure, and therefore, the scope of the present disclosure is not limited to FIG. 5A to FIG. 5D The structure of the accuracy measuring device shown.

[0082] The structure of the precision measuring device is described above. Based on the structure, an embodiment of the present disclosure can also provide a precision measuring method. The precision measuring method includes: a data detection device detects the detected object to obtain detection data, and transmits the detection data to a controller; the controller calculates the offset value between the detection data and the reference data, and compares the offset value with a threshold value, and outputs an alarm message when the offset value is greater than the threshold value; and the alarm device alarms after receiving the alarm message. This can realize automatic detection of accuracy, thereby improving the efficiency and measurement accuracy of precision measurement, saving manpower, and reducing the manpower requirements of measurement tasks.

[0083] In some embodiments, taking a position detection device as a data detection device as an example, the above-mentioned accuracy detection method includes: the position detection device detects the position data of the detected object, and transmits the position data to a controller; the controller calculates a first offset value between the detected position data and the position reference data, and compares the first offset value with a first threshold value, and outputs a first alarm message when the first offset value is greater than the first threshold value; and the alarm device sounds an alarm after receiving the first alarm message.

[0085] Figure 6 is a flow chart showing a method for measuring accuracy according to some embodiments of the present disclosure. Figure 6 As shown, the accuracy measurement method includes steps S602 to S614.

[0086] In step S602, the precision measurement process is scheduled. For example, the pallet precision measurement process is scheduled with one click through the HMI (Human Machine Interface).

[0087] In step S604, the precision measurement task is performed. For example, the position data of the detected object is detected by using a position detection device, and the position data is transmitted to a controller, and the controller calculates a first offset value between the detected position data and the position reference data. For another example, the distance detection device is used to detect the distance data from the distance detection device to the detected object, and the distance data is transmitted to the controller, and the controller calculates a second offset value between the detected distance data and the distance reference data. For example, the robot can carry a camera and / or a rangefinder to perform a photo-taking and distance-measuring task.

For example, the offset value includes the first offset value and the second offset value described above, and the threshold value includes a first threshold value corresponding to the first offset value and a second threshold value corresponding to the second offset value. For example, step S606 includes: determining whether the first offset value is greater than the first threshold value. For another example, step S606 includes: determining whether the second offset value is greater than the second threshold value. If the offset value is greater than the threshold value, the process proceeds to step S608; otherwise, the process proceeds to step S610.

[0089] In step S608, an alarm is executed, for example, an alarm is issued for abnormal data through the HMI.

[0090] In step S610, the data is uploaded to the EAP (Enterprise Application Platform) software. That is, when the offset value is less than or equal to the threshold, the detected position data and distance data and the calculated offset value are uploaded to the EAP software.

[0091] In step S612, the data is uploaded to the EAP software. That is, when the offset value is greater than the threshold, the detected position data and distance data and the calculated offset value are uploaded to the EAP software.

[0092] In step S614, manual processing is performed. For example, manual processing (such as repair) is performed on the pallets that do not meet the accuracy requirements.
