[0108] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.
[0109] Some embodiments of the present application are described in detail. The following embodiments and features of the embodiments can be combined with each other without conflict.
[0110] Referring to Figure 1 The present embodiment provides a measuring device 100. The measuring device 100 can be configured as a flash measuring imager. The flash measuring imager is used for detecting by quickly photographing a target object (such as a workpiece), and has the advantages of fast speed, high precision and simple operation. The flash measuring imager can be applied to the fields of 3C electronics, aerospace, automobile manufacturing, digital twin, etc. Through image information detection of the workpiece, the processing technology of the workpiece can be adjusted to improve the product quality of the workpiece.
[0111] In some embodiments, the flash measuring imager can be electrically connected to a computer 201, and the computer 201 is electrically connected to a keyboard 202, a mouse 203 and a display 204, so that an operator can perform data recording and measurement control operations through the keyboard 202, the mouse 203 and the display 204.
[0112] Referring to Figure 2 and Figure 3 The measuring device 100 includes a bearing assembly 10, an image acquisition module 20 and a first light source 31. The bearing assembly 10 has a mounting surface P1 and a bearing surface P2 arranged opposite to each other along a first direction Z, and the bearing surface P2 is used for bearing the target object. The image acquisition module 20 is movably arranged on one side of the bearing surface P2 along the first direction Z and faces the bearing surface P2, and the image acquisition module 20 is used for acquiring image information of the target object. The first direction Z is obliquely intersected with or perpendicular to the bearing surface P2. The first light source 31 is arranged on one side of the bearing surface P2 and faces the bearing surface P2, and is movable along the first direction Z.
[0113] According to the measuring device 100 of the present embodiment, in the actual measurement process, according to the actually acquired image information, when the imaging effect of the image information is not ideal, the interval between the image acquisition module 20 and the bearing surface P2 along the first direction Z is kept fixed, and the interval between the first light source 31 and the bearing surface P2 along the first direction Z is adjusted, so that the light emitted by the first light source 31 on the target object changes, and thus the light reflected by the target object to the image acquisition module 20 also changes, so that the image information acquired by the image acquisition module 20 changes, thereby improving the imaging quality of the target object and improving the detection precision of the image measurement.
[0114] In some embodiments, the measuring device 100 further includes a control module (not shown in the figure) and a calculation module (not shown in the figure).
[0115] The computing module can acquire image information and determine the definition of the image information, and then transmit a signal to the control module, which controls the first light source 31 to move closer to or farther away from the bearing surface P2 along the first direction Z, so that the image acquisition module 20 acquires more clear image information. The computing module can have a pre-set software algorithm, so that during the measurement process, control information is transmitted to the control module based on the real-time acquired image information, realizing accurate control of the measuring device 100, meeting the measurement requirements of automatic measurement, simplifying the image measurement steps of the target part, improving the measurement efficiency, reducing the professional level requirements for the operator, and improving the application range of the measuring device 100.
[0116] Alternatively, the operator can determine the definition of the image information by moving the first light source 31 relative to the image acquisition module 20.
[0117] In some embodiments, referring to Figure 2 , the image acquisition module 20 includes a lens assembly 21 and a camera assembly 22. The lens assembly 21 is movably arranged along the first direction Z relative to the bearing assembly 10. The camera assembly 22 is connected to one end of the lens assembly 21 away from the bearing assembly 10 and is located on the side of the lens assembly 21 close to the first displacement assembly 71 along the second direction X.
[0118] In some embodiments, referring to Figure 2 , the camera assembly 22 includes two CCD cameras 221. The two CCD cameras 221 are spaced apart along the third direction Y on the lens assembly 21, one of which can acquire large-format image information acquisition, and the other can acquire small field of view and high-precision image information acquisition, so that the detection efficiency of the image can be further improved.
[0119] The lens assembly 21 is a double-sided telecentric lens, which has two fields of view of a wide range of view and a high-precision view to meet different requirements of image information acquisition. Specifically, the double-sided telecentric lens can be a low-distortion double-sided telecentric lens. In the wide range of view, the measurement range of the image acquisition module 20 is large, and fast measurement of the target part can be realized; for example, the measurement field of view of the wide range of view is 100*100mm, the optical magnification is 0.016x, and the resolution is 5um. In the high-precision view, the measurement range of the image acquisition module 20 is relatively small compared to the measurement range of the wide range of view, but the resolution is higher, and high-precision measurement can be realized; for example, the measurement field of view of the high-precision view is 6*6mm, the optical magnification is 2x, and the resolution is 1um. In the actual measurement process, the wide-view lens can be used for fast measurement for relatively large features, and the high-precision view can be used for fine measurement for features with high accuracy requirements.
[0120] The lens assembly 21 further comprises a light path transmission part. The double-side telecentric lens shares one light path transmission part, which is a telecentric main light path and has the same focal length and different optical magnifications. The double-side telecentric lens can measure in a wide range of view and high-precision view in sequence, and can also measure at the same time to meet different measurement requirements.
[0121] In other embodiments, the camera assembly 22 can be provided with a single CCD camera 221, and the lens assembly 21 is correspondingly provided with a single-view optical lens. The number of cameras of the camera assembly 22 and the type of the lens assembly 21 can be adjusted according to actual detection requirements.
[0122] In some embodiments, referring to Figure 2 and Figure 3 , the measurement device 100 further comprises a base 60. The base 60 comprises a bottom 61 and a side 62. The bottom 61 extends along two directions. The carrying assembly 10 is arranged on the bottom 61. The side 62 is connected to one end of the bottom 61 along the second direction X and extends along the first direction Z.
[0123] In some embodiments, referring to Figure 2 and Figure 3 , the measurement device 100 further comprises a measurement button 63. The bottom 61 is provided with a mounting slope at one end away from the side 62 along the second direction X, and the measurement button 63 is arranged on the mounting slope. The measurement button 63 is configured to be electrically connected with the control module to control the operation of the measurement device 100.
[0124] In some embodiments, referring to Figure 2 to Figure 4 , the measurement device 100 further comprises a first displacement assembly 71 and a second displacement assembly 72. The first displacement assembly 71 is drivingly connected to the image acquisition module 20 and is used to drive the image acquisition module 20 to move along the first direction Z. The second displacement assembly 72 is drivingly connected to the first light source 31 and is used to drive the first light source 31 to move along the first direction Z.
[0125] In this way, during the measurement process, the first displacement assembly 71 can drive the image acquisition module 20 and the first light source 31 to move along the first direction Z relative to the carrying assembly 10 at the same time. After the image acquisition module 20 is in place, the second displacement assembly 72 is controlled to drive the first light source 31 to move according to the image information acquired by the image acquisition module 20 until the precision of the image information acquired by the image acquisition module 20 meets the requirements.
[0126] In some embodiments, referring to Figure 2 to Figure 4The second displacement assembly 72 is in transmission connection with the first displacement assembly 71 and can move along the first direction Z under the driving of the first displacement assembly 71. In this way, the first light source 31 can move with the image acquisition module 20, thereby improving the moving efficiency of the first light source 31, and the second displacement assembly 72 can adopt a higher-precision driving device, thereby improving the moving precision of the first light source 31.

In this way, the space on the side of the bottom portion 61 along the second direction X is not occupied by the first displacement assembly 71, thereby ensuring the space occupancy rate of the image acquisition module 20 and the bearing assembly 10 and improving the user experience.
[0128] In some embodiments, referring to Figure 4 The first displacement assembly 71 comprises a first driving member 711, a first lead screw 712 and a first movable pair 713.

The first sensing sheet 861 is connected to the first movable pair 713 and can be detected by the two sensors 862. When the sensor 862 detects the first sensing sheet 861, an electrical signal can be sent to the first driving member 711 to stop driving the first lead screw 712 to rotate, thereby limiting the movement of the first movable pair 713 along the first direction Z, to avoid the collision between the first light source 31 or the image detection module and the target piece, and to ensure the operation safety of the measuring device 100.
[0131] Specifically, the sensor 862 can be an optical sensor 862.
