Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0063] In order to achieve the size measurement of large-size thin plates 1000, the present application relates to a large-size thin plate size measurement device, which uses a camera to take pictures of large-size thin plates 1000 to obtain data with high accuracy. The device does not require human intervention, avoiding deviations introduced by human participation.

[0064] See also Figures 1 to 8 The large-size thin plate measuring device includes a first motion platform 100, a fixture assembly 500, a measuring assembly 300, a second motion platform 200 and a light source assembly 600.

[0065] In some embodiments of the present application, the measuring assembly 300 is placed on the first motion platform 100 via the sliding frame 400. When the first motion platform 100 is working, the sliding frame 400 and the measuring assembly 300 thereon are driven to slide.

[0066] See also Figure 2 The first motion platform 100 includes a lead screw module 110, a third guide rail 120 and a fourth guide rail 130 arranged in parallel.

[0067] The third guide rail 120 is provided with a third slider (not shown) sliding along it, and the number of the third slider can be set as needed; the fourth guide rail 130 is provided with a fourth slider (not shown) sliding along it, and the number of the fourth slider can be set as needed.

[0068] The nut on the lead screw in the lead screw module 110 is connected to the third slider or the fourth slider, and the sliding frame 400 is connected to the third slider and the fourth slider respectively.

[0069] In some embodiments of this application, see Figure 4 The sliding frame 400 includes a transverse beam 410 and a first longitudinal side beam 420 and a second longitudinal side beam 430 connected to both ends of the transverse beam 410 .

[0070] The first longitudinal side beam 420 is connected to the third slider, the second longitudinal side beam 430 is connected to the fourth slider, and the third slider or the fourth slider is connected to the nut of the screw in the screw module 110, so that the sliding frame 400 slides along the length direction of the screw when the screw is working.

[0071] See also Figure 1 and Figure 2 , the fixture assembly 500 is used to carry the large-size thin plate 1000. In some embodiments of the present application, see Figure 2 The clamp assembly 500 is disposed below the transverse beam 410 and between the first longitudinal side beam 420 and the second longitudinal side beam 430 .

[0072] See also Figure 4 The measuring assembly 300 includes a plurality of cameras (eg, a first camera 311) arranged in parallel, the lenses of which are all directed toward the large-size thin plate 1000 (see Figure 2 ), the measuring assembly 300 is mounted on the sliding frame 400 and the large-sized thin plate 1000 is moved along the length direction of the third guide rail 120 (see Figure 2 The length of the large-size thin plate 1000 (in the direction of the solid arrow) is shorter than the length of the third guide rail 120. Therefore, when the sliding frame 400 slides along the third guide rail 120 and the fourth guide rail 130 and drives the multiple cameras to slide, the multiple cameras can fully acquire the data of the large-size thin plate 1000.

[0073] Measuring the dimensions of thin plates (such as length and width) based on these data is a commonly used algorithm in the measurement industry, and the technical solution of this application does not involve any changes to this algorithm.

[0074] Therefore, multiple cameras acquire data, which improves data acquisition efficiency, and the large amount of data acquired at the same time facilitates the measurement of multiple elements of the thin plate.

[0075] In the field of measurement technology, the light source assembly 600 is provided in conjunction with a camera to improve the accuracy of data collection and dimension measurement.

[0076] In some embodiments of this application, see Figure 3 The light source assembly 600 is set on the second motion platform 200, and the second motion platform 200 is linked with the first motion platform 100, so that the light source assembly 600 moves with the camera to provide backlight for the camera.

[0077] See also Figure 3 The second motion platform 200 may include a power output portion, a first guide rail 230 and a second guide rail 240 arranged in parallel, and the directions of the first guide rail 230, the second guide rail 240, the third guide rail 120 and the fourth guide rail 130 are parallel to each other.

[0078] In some embodiments of the present application, the power output unit includes a drive motor 210 and a power transmission mechanism, which may be a conveyor belt, a gear rack, or the like.

[0079] In some embodiments of the present application, the power transmission mechanism is a conveyor belt 220 , and the transmission direction of the conveyor belt 220 is along the length direction of the first guide rail 230 .

[0080] The first guide rail 230 is provided with a first slider (not shown) sliding along it, and the number of the first sliders can be set as needed; the second guide rail 240 is provided with a second slider (not shown) sliding along it, and the number of the second sliders can be set as needed.

[0081] The first slider or the second slider is connected to the conveyor belt 220 through a first connecting seat (not shown), and the light source assembly 600 is connected to the first slider and the second slider respectively through a second connecting seat (not shown). In this way, when the driving motor 210 is working, the power output by the driving motor 210 is transmitted to the conveyor belt 220, and then transmitted to the first connecting seat and the first slider or the second slider, so that the light source assembly 600 can slide along the first guide rail 230 and the second guide rail 240 under the drive of the first slider and the second slider.

[0082] In some embodiments of this application, see Figure 2 and Figure 3 The measuring component 300 is located on one side of the large-size thin plate 1000 and is used to take pictures of the surface of one side of the large-size thin plate 1000 (after taking pictures of the surface of one side, it is turned over to take pictures of the other opposite side surface), and the light source component 600 is located on the other side of the large-size thin plate 1000. Therefore, in some embodiments of the present application, the first guide rail 230 and the second guide rail 240 are both located on the inner side of the third guide rail 120 and the fourth guide rail 130.

[0083] In some embodiments of the present application, in order to achieve the placement of the large-sized thin plate 1000, see Figures 5 to 8The clamp assembly 500 includes a supporting plate 510 and two rows of supporting legs (denoted as a first row of supporting legs 520 and a second row of supporting legs 530), wherein the top surface of the supporting plate 510 is used to support the large-size thin plate 1000, and each supporting leg is used to support the supporting plate 510.

[0084] The length direction of the supporting plate 510 , the length direction of the large-size thin plate 1000 , the length direction of the third guide rail 120 , and the arrangement direction of each column of support legs are all consistent.

[0085] In some embodiments of the present application, refer back to Figure 2 The first guide rail 230 and the second guide rail 240 are both located between the first column of support legs 520 and the second column of support legs 530 and extend through the bottom of the carrier plate 510 . The light source assembly 600 is also located under the carrier plate 510 .

[0086] As described above, the third guide rail 120 and the fourth guide rail 130 are both located on the outside of the first column of support legs 520 and the second column of support legs 530, the supporting plate 510 is located between the first longitudinal side beam 420 and the second longitudinal side beam 430, and the measuring component 300 is located above the supporting plate 510, so that when the measuring component 300 slides along the first guide rail 230 and the second guide rail 240 driven by the sliding frame 400, the camera in the measuring component 300 scans and photographs the large-size thin plate 1000 carried on the top surface of the supporting plate 510.

[0087] As described above, the light source assembly 600 is located below the carrier plate 510 and the measuring assembly 300 is located above the carrier plate 510. Therefore, in order for the light source assembly 600 to provide backlight for the camera in the measuring assembly 300, see Figure 5 A number of through-holes (the through-holes 511 are marked in the example) are provided on the carrier plate 510. The backlight emitted by the light source assembly 600 passes through the through-holes 511 to provide backlight for the camera when taking pictures of the large-size thin plate 1000, thereby improving the accuracy of data collection.

[0088] In some embodiments of the present application, in order to better position the large-size thin plate 1000, the clamp assembly 500 also includes a first positioning portion, a second positioning portion and an adsorption portion. The first positioning portion and the second positioning portion position the thin plate 1000 in different directions of the plane where the top surface of the supporting plate 510 is located. The adsorption portion is used to adsorb the thin plate 1000 from a direction perpendicular to the supporting plate 510 to ensure that the thin plate 1000 is positioned reliably and accurately.

[0089] For the convenience of description, the width direction of the thin plate 1000 (ie, the vertical length direction of the first guide rail 230 ) is defined as the Y direction, and the length direction of the thin plate 1000 is defined as the X direction.

[0090] The first positioning part includes multiple first positioning cylinders 540, all of which are located on the supporting plate 510 and are used to position the large-size thin plate 1000 in the Y direction. The second positioning part includes multiple second positioning cylinders 550, all of which are located on the supporting plate 510 and are used to position the large-size thin plate 1000 in the X direction.

[0091] The first positioning cylinder 540 and the second positioning cylinder 550 are respectively implemented by telescopic cylinders.

[0092] A positioning plate (not shown) is provided at the free end of the telescopic rod of the telescopic cylinder. When the telescopic rod is extended, the positioning plate applies a force to the corresponding side wall of the thin plate 1000, and when the telescopic rod is retracted, the positioning plate withdraws the force on the corresponding side wall.

[0093] In some embodiments of the present application, a portion of the plurality of first positioning cylinders 540 may be disposed on one side of the top surface of the carrier plate 510 in the Y direction, and another portion may be disposed on the other side of the top surface of the carrier plate 510 in the Y direction.

[0094] In some embodiments of the present application, a portion of the plurality of second positioning cylinders 550 may be disposed on one side of the top surface of the carrier plate 510 in the X direction, and another portion may be disposed on the other side of the top surface of the carrier plate 510 in the X direction.

[0095] In order to avoid damage to the sheet 1000 caused by different forces applied by different numbers of positioning cylinders on different sides, in some embodiments of the present application, see Figure 6 The first positioning portion also includes a plurality of first positioning blocks 570, and the second positioning portion also includes a plurality of second positioning blocks 580. The plurality of first positioning blocks 570 are fixed on one side of the top surface of the carrier plate 510 in the Y direction, and the plurality of second positioning blocks 580 are fixed on one side of the top surface of the carrier plate 510 in the X direction.

[0096] Multiple first positioning cylinders 540 are arranged on the other side of the top surface of the carrier plate 510 in the Y direction, and multiple second positioning cylinders 550 are arranged on the other side of the top surface of the carrier plate 510 in the X direction. In this way, when the thin plate 1000 is placed on the top surface of the carrier plate 510, one side of the thin plate 1000 in the Y direction is first abutted against each first positioning block 570 and one side of the thin plate 1000 in the X direction is abutted against each second positioning block 580, and then the telescopic rods of the first positioning cylinders 540 are controlled to extend so that the positioning plate at their end abuts against the other side of the thin plate 1000 in the Y direction, and the telescopic rods of the second positioning cylinders 550 are extended so that the positioning plate at their end abuts against the other side of the thin plate 1000 in the X direction, thereby realizing the X- and Y-direction positioning of the thin plate 1000.

[0097] In some embodiments of the present application, the adsorption portion may be a vacuum suction cup 560 component.

[0098] See also Figure 7 and Figure 8 A plurality of placement areas 512 that penetrate the thickness of the top surface are opened at different positions on the top surface of the carrier plate 510, and a suction cup beam (not shown) is installed in the placement area 512. One end of the suction cup beam passes through the opening on the bottom surface of the carrier plate 510 and is connected to an external air pump (not shown). A vacuum suction cup 560 is provided at the other end of the suction cup beam close to the opening on the top surface of the carrier plate 510. The air pump is connected to the vacuum suction cup 560 through the air channel in the suction cup beam. Through the action of the air pump, the vacuum suction cup 560 can adsorb or detach the thin plate 1000 on the top surface of the carrier plate 510.

[0099] In some embodiments of the present application, the adsorption portion may also be a negative pressure chamber (not shown), and multiple negative pressure chambers are opened at different positions on the top surface of the supporting plate 510. The negative pressure chamber can be connected to a negative pressure production component (not shown) through a negative pressure pipeline (not shown).

[0100] When the negative pressure production component is turned on, the negative pressure production component extracts the air in the negative pressure chamber to form a vacuum negative pressure. At this time, since the thin plate 1000 is placed on the top surface of the carrier plate 510, the thin plate 1000 is firmly adsorbed and fixed on the top surface of the carrier plate 510 under the adsorption effect of the super strong vacuum negative pressure in the negative pressure chamber, thereby ensuring the stability of the thin plate 1000.

[0101] The thin plate 1000 is stabilized by an adsorption action, which is a soft contact on the thin plate 1000 and does not cause hard contact damage to the thin plate 1000.

[0102] In some embodiments of the present application, refer back to Figure 4 The measuring component 300 includes a camera mounting portion and a light source mounting portion.

[0103] The camera mounting portion is used to mount the corresponding camera on the sliding frame 400 , and the light source mounting portion is used to mount the corresponding light source for providing illumination for the lens of the corresponding camera when taking pictures on the sliding frame 400 .

[0104] As described above, the sliding frame 400 includes a transverse beam 410, a first longitudinal side beam 420 and a second longitudinal side beam 430. Therefore, in some embodiments of the present application, in order to facilitate the arrangement of multiple cameras, the multiple cameras are arranged in two rows (recorded as the first row of cameras 310 and the second row of cameras 320). The first row of cameras 310 and the second row of cameras 320 are respectively installed on opposite sides of the transverse beam 410 and the arrangement direction of each row of cameras is along the width direction of the thin plate 1000, and the number of the first row of cameras 310 and the number of the second row of cameras 320 are the same.

[0105] For the first row of cameras 310 and the second row of cameras 320 , the camera mounting portion includes a first camera mounting portion for mounting the first row of cameras 310 and a second camera mounting portion for mounting the second row of cameras 320 , and the first camera mounting portion and the second camera mounting portion have the same structure.

[0106] The light source mounting portion includes a first light source mounting portion for mounting the light sources of the first row of cameras 310 and a second light source mounting portion for mounting the light sources of the second row of cameras 320 , and the structures of the first light source mounting portion and the second light source mounting portion are the same.

[0107] The following description takes the first camera mounting portion and the first light source mounting portion as examples.

[0108] See also Figure 4 The first camera mounting portion includes a first camera mounting seat 330 and multiple first camera mounting mechanisms 340. The first camera mounting seat 330 is mounted on the sliding frame 400, specifically on one side of the transverse beam 410, and multiple first camera mounting mechanisms 340 are all mounted on the first camera mounting seat 330.

[0109] The length direction of the first camera mounting seat 330 is along the arrangement direction of the first row of cameras 310 .

[0110] A first camera mounting mechanism 340 includes a first camera main clamping block (not labeled) and a first camera auxiliary clamping block (not labeled) connected to each other, wherein the first camera main clamping block is fixed to the first camera mounting base 330 .

[0111] In some embodiments of the present application, in order to adjust the position of the camera, a long strip hole (not shown) can be opened on the first camera main clamp, and a plurality of assembly holes (not shown) corresponding to the long strip hole are opened on the first camera mounting seat 330. The arrangement direction of the plurality of assembly holes corresponds to the length direction of the long strip hole and is perpendicular to the length direction of the third guide rail 120. Thus, the distance between the camera lens and the thin plate 1000 can be adjusted.

[0112] The first light source mounting part includes a first light source mounting seat 350 and multiple first light source mounting mechanisms 360. The first light source mounting seat 350 is installed on the sliding frame 400. Specifically, the first light source mounting seat 350 is U-shaped and installed on one side of the transverse beam 410. Multiple first light source mounting mechanisms 360 are all installed on the first light source mounting seat 350.

[0113] A first light source mounting mechanism 360 is used to fix a corresponding light source that provides illumination for the first lens 312 of the first camera 311 in the first row of cameras 310 .

[0114] In order to provide sufficient illumination for the camera lens and improve the photographic effect, in some embodiments of the present application, a ring light source 380 and a coaxial light source 370 are configured for a camera. Therefore, in order to install the ring light source 380 and the coaxial light source 370, see Figure 4 The first light source mounting mechanism 360 includes a first light source mounting plate 361 and a second light source mounting plate 362 .

[0115] The first light source mounting plate 361 is installed on the first light source mounting seat 350, and is used to fix the coaxial light source 370 that provides coaxial light to the first lens 312; the second light source mounting plate 362 is installed on the first light source mounting plate 361, and is used to fix the annular light source 380 that provides annular light to the first lens 312. The annular light source 380 is closer to the large-size thin plate 1000 than the coaxial light source 370.

[0116] In order to protect the measurement component 300, in some embodiments of the present application, see Figure 1 The measuring device further includes a cover 700 fixed to the sliding frame 400 for covering the measuring component 300 without shielding the camera lens.

[0117] The usage process of the above-mentioned measuring device is described as follows.

[0118] (1) A large-sized thin plate 1000 is fed from the assembly line. A person or a robot takes the thin plate 1000 from the assembly line and places the thin plate 1000 with its A side facing upward on the top surface of the carrier plate 510.

[0119] (2) The telescopic rod of the Y-axis positioning cylinder in the fixture assembly 500 extends to clamp the thin plate 1000 in the Y-axis, and the telescopic rod of the X-axis positioning cylinder extends to clamp the thin plate 1000 in the X-axis. The vacuum pump in the fixture assembly 500 works, and the vacuum suction cup 560 sucks the thin plate 1000, and the thin plate 1000 is positioned.

[0120] (3) Control the first motion platform 100 and the second motion platform 200 to operate, so that the measuring assembly 300 and the light source assembly 600 move simultaneously. The multiple cameras in the measuring assembly 300 take flying photos of the thin plate 1000. After the photos are taken, the measuring assembly 300 and the light source assembly 600 return to the origin.

[0121] (4) The telescopic rod of the Y-axis positioning cylinder is retracted, the telescopic rod of the X-axis positioning cylinder is retracted, and the vacuum suction cup 560 is disconnected from the thin plate 1000.

[0122] (5) The thin plate 1000 is taken out manually or by a robot, turned over, and then placed on the top surface of the carrier plate 510 with the B side facing upward.

[0123] (6) Repeat the above process (2) to (4) to complete the data acquisition of the thin plate 1000.

[0124] Afterwards, the dimensions of the thin plate 1000 may be measured using existing algorithms.

[0125] In some embodiments of the present application, refer back to Figure 1 and Figure 2 The measuring device further includes a base 800 and a peripheral frame 900 .

[0126] The base 800 can be a marble base 800 , on which the first motion platform 100 (and the measuring assembly 300 and the sliding frame 400 thereon), the fixture assembly 500 and the second motion platform 200 (and the light source assembly 600 thereon) are all placed.

[0127] The first motion platform 100 , the fixture assembly 500 and the second motion platform 200 are all located within the outer frame 900 , thereby improving the aesthetics of the measuring device.
