The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.
[0039] In order to be able to simulate the movement of the thin-film material on the production line and facilitate verifying the detection performance of the vision detection device for the moving thin film, this embodiment provides a calibration tooling and a calibration system. The following will be described in detail in combination with Figures 1 to 4 the specific content of this embodiment. It should be noted that the first direction mentioned in this embodiment is Figure 1 the X direction in Figure 1 the second direction mentioned in this embodiment is Figure 1 the Y direction in
[0040] As Figure 1 shown in combination with Figure 2 the calibration tooling 100 in this embodiment includes a mounting base 1 and a translation module 2. The translation module 2 includes a slide table 21, an adapter plate 22, and a sample carrier 23. The slide table 21 is disposed on the mounting base 1 and can reciprocate along the first direction. One end of the adapter plate 22 is connected to the slide table 21, and the other end of the adapter plate 22 is connected to the sample carrier 23. The sample carrier 23 is provided with a hollow structure 231, and the sample carrier 23 is used to place samples. The samples include thin films with typical defects such as pinholes, oil stains, black spots, scratches, etc. of different sizes and specifications or pinholes of different precisions.
[0041] In short, for the calibration tooling 100 provided in this embodiment, the sample carrier 23 is connected to the slide table 21 through the adapter plate 22. The slide table 21 is disposed on the mounting base 1, and the thin-film material to be detected is placed on the sample carrier 23. Since the sample carrier 23 is designed with a hollow structure 231, it is convenient for light to pass through the thin film. The movement of the sample carrier 23 is driven by the slide table 21 to simulate the movement of the thin-film material on the production line. The calibration tooling 100 is installed below the vision detection device 6. By replacing samples with different defects on the sample carrier 23, it is used to verify the defect detection performance of the vision detection device 6 for the thin-film material, without starting a large-scale surface defect detection device, reducing the verification cost and improving the calibration efficiency.
[0042] Furthermore, the adapter plate 22 in this embodiment includes a first folding plate 221, a second folding plate 222, and a third folding plate 223. The first folding plate 221 and the third folding plate 223 are parallel and spaced apart at both ends of the second folding plate 222. The first folding plate 221 is connected to the slide 21, and the sample stage 23 is detachably connected to the third folding plate 223. By bending the adapter plate 22, the sample stage 23 can be located at a side lower position of the slide 21, thereby avoiding structural interference of the sample stage 23 during movement.
[0043] Furthermore, a first connection hole 232 is provided on the sample stage 23, and a plurality of second connection holes 2231 are provided at intervals along the first direction on the third folding plate 223, and a fastener passes through the first connection hole 232 and is connected to one of the second connection holes 2231. By adding a plurality of second connection holes 2231, on the one hand, the installation position of the sample stage 23 on the third folding plate 223 can be adjusted, and on the other hand, a plurality of sample stages 23 can be installed on the third folding plate 223, thereby improving the detection efficiency.
[0044] Optionally, the sample stage 23 is provided with a plurality of third connection holes 233 at intervals around the hollow structure 231. The film can be connected to the third connection holes 233 by screws passing through the film to achieve a stable connection between the film and the sample stage 23, thereby preventing the film from falling during movement.
[0045] Furthermore, the inspection tool 100 also includes a speed detection module 3, which is arranged on the mounting base 1 and is used to detect the moving speed and moving direction of the slide 21. By adding the speed detection module 3, it is convenient to know the moving speed and moving direction of the film, and it is convenient to adjust the parameters of the visual inspection device 6 in a targeted manner.
[0046] Exemplarily, the speed detection module 3 includes a mounting bracket 31, an encoder 32 and a friction wheel 33. The mounting bracket 31 is arranged on the mounting base 1, the encoder 32 is arranged on the mounting bracket 31 and is coaxially connected with the friction wheel 33. A friction plate 28 is arranged on the side of the slide 21 away from the adapter plate 22, and the friction plate 28 is in transmission contact with the friction wheel 33. In the process of the slide 21 driving the friction plate 28 to move along the first direction, the friction wheel 33 can drive the encoder 32 to rotate through the transmission contact between the friction plate 28 and the friction wheel 33. There are three main methods for the encoder 32 to measure the speed, namely, the M method, the T method and the MT method. These methods are based on the working principle and signal output of the encoder 32, and the speed of the object is calculated by measuring the number of pulses of the encoder 32. Through the communication connection between the encoder 32 and the visual detection device 6, it can be ensured that the frequency of the visual detection device 6 taking pictures is synchronized with the sample movement speed, so that the pictures are not deformed or distorted.
[0047] Further, the translation module 2 further includes a rotation driving mechanism, a first transmission rod 24 and a second transmission rod 25. The rotation driving mechanism is arranged on the mounting base 1. The output shaft of the rotation driving mechanism is rotatably connected to the first transmission rod 24. One end of the second transmission rod 25 is hinged to the first transmission rod 24, and the other end of the second transmission rod 25 is hinged to the slide table 21. The rotation driving mechanism includes a speed-regulating motor 27 and a gearbox 26. The input shaft of the gearbox 26 is drivingly connected to the speed-regulating motor 27, and the output shaft of the gearbox 26 is coaxially connected to the first transmission rod 24. Among them, the first transmission rod 24, the second transmission rod 25 and the slide table 21 form a crank-slider mechanism. The slide table 21 can be moved along the first direction by the drive of the speed-regulating motor 27. The speed-regulating motor 27 serves as the power source for the reciprocating motion and, in cooperation with the speed-regulating function of the controller, enables the sample stage 23 to work at a set speed.
[0048] Furthermore, the translation module 2 further includes a guiding track 29. The guiding track 29 is arranged on the mounting base 1 and extends along the first direction. The slide table 21 is slidably arranged on the guiding track 29. By adding the guiding track 29, the slide table 21 can always be kept moving along the first direction. The translation module 2 converts the rotational motion into a front-back linear motion in terms of the motion form. In cooperation with the high-precision guiding track 29, the sample stage 23 can maintain low vibration during the high-speed front-back motion.
[0049] Optionally, in some application scenarios, the translation module 2 further includes a belt conveyor mechanism. The belt conveyor mechanism is arranged on the mounting base 1, and the slide table 21 is fixedly arranged on the conveyor belt of the belt conveyor mechanism.
[0050] Further, the calibration tooling 100 further includes a lifting module 4. The lifting module 4 and the translation module 2 are respectively located on both sides of the mounting base 1 along the second direction. One end of the lifting module 4 is connected to the mounting base 1, and the other end of the lifting module 4 can be connected to an external fixture. By adding the lifting module 4, it is convenient to move the mounting base 1 up and down along the third direction so that the film on the sample stage 23 is located at the focal point of the vision inspection device 6.
[0051] As Figure 3 Combined Figure 4 shown, this embodiment further provides a calibration system. The calibration system includes a support frame 5 and the above-mentioned calibration tooling 100. The support frame 5 includes a first cross beam 51 and a second cross beam 52 that are parallel and spaced apart along the third direction. In this embodiment, the first cross beam 51 is located above the second cross beam 52. A plurality of vision inspection devices 6 are used to be installed at intervals along the second direction on the first cross beam 51. An installation arm 53 that can move along the second direction is arranged on the second cross beam 52, and the calibration tooling 100 is arranged on the installation arm 53. It is possible to verify the defect detection performance of a plurality of vision inspection devices 6 without starting a large-scale surface defect detection device, reducing the verification cost.
[0052] Specifically, as Figure 2 shown in combination with Figure 4 Figure 6, the lifting module 4 includes a mounting plate 41, a lifting plate 43, and a cross-link assembly 42 disposed between the mounting plate 41 and the lifting plate 43. The mounting plate 41 is connected to the mounting arm 53, and the lifting plate 43 is connected to the mounting base 1. By deforming the cross-link assembly 42, the lifting plate 43 can drive the mounting base 1 to move up and down.
[0053] In summary, in this embodiment, by adopting the technical means of combining the translation module 2 and the speed detection module 3, the actual movement state of the thin film material on the production line is simulated and feedback is provided. Without starting the production line conveying device, the user can evaluate the dynamic detection ability of the vision detection device 6 at a specified speed, reducing energy consumption and manpower.
