[0005] Among them, the first calibration component is a white sheet; the second calibration component includes a first boss and a second boss arranged in a staggered array; the third calibration component is a strip; and the fourth calibration component is a gray sheet.

[0006] Furthermore, the first calibration component is fixed on the placement table through a first pressing plate.

[0007] Furthermore, both the first and second bosses are provided with columnar protrusions extending outward; the top end faces of the columnar protrusions are painted with a color different from the first and second bosses connected thereto; and the height of the first boss is much greater than that of the second boss.

[0008] Furthermore, the third calibration component includes a base plate; the base plate is provided with a first height platform, a second height platform and a third height platform on the upper side along the vertical direction; the distance between adjacent first height platforms, second height platforms and third height platforms is 0.5 mm.

[0009] Furthermore, the thickness of the fourth calibration component is 3 mm.

[0010] Furthermore, a concave placement groove is provided on the top of the placement table; the placement groove is symmetrical front to back and a first pressing plate is detachably installed thereon.

[0011] Furthermore, the elastic member is a disc spring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1) This utility model is meticulously equipped with a first calibration component (a white sheet), a second calibration component (with raised platforms of varying heights and colored columnar protrusions), a third calibration component (a strip with raised platforms of varying heights), and a fourth calibration component (a gray sheet). These unique calibration components provide a rich and diverse reference standard for the visual inspection system, fully meeting different calibration requirements and significantly improving calibration accuracy.

[0015] 2) The height difference between the first and second bosses in the second calibration component of the utility model, and the precise 0.5mm spacing between the height platforms in the third calibration component, provide an extremely accurate reference for the visual inspection system in measuring height and size, greatly improving the accuracy of object height and size detection.

[0016] 3) The first calibration component of the utility model is fixed to the placement table by the first pressure plate. The placement slot on the top of the placement table and the detachable first pressure plate design enable the calibration component to be firmly fixed on the placement table, avoiding movement or shaking during the calibration process, and effectively ensuring the stability and accuracy of the calibration.

[0017] 4) The retractable placement table on the top of the calibration bracket of the utility model can flexibly adjust the height according to different usage requirements, perfectly adapting to different visual inspection equipment and inspection scenarios, greatly improving the versatility and flexibility of the system.

[0018] 5) The elastic member (disc spring) between the placement table and the calibration bracket of the utility model can buffer external forces to a certain extent, providing good protection for the calibration system and visual inspection equipment. At the same time, it can also adapt to different working environments and conditions, effectively improving the stability and reliability of the system.

[0019] 6) The concave positioning shoulder along the length of the placement table of the utility model helps to accurately position the calibration components when placing and adjusting them, greatly improving the convenience and accuracy of operation, and also facilitating the rapid and accurate arrangement of the calibration system in different usage scenarios.

[0020] 7) The visual inspection calibration system of this utility model integrates multiple calibration components into a retractable placement table, which is compact and easy to carry and use. When calibration is needed, it can be quickly deployed, greatly saving time and labor costs.

[0021] 8) The detachable design and fixing method of the calibration component of the utility model make it very convenient to maintain and replace the calibration component when it is damaged or needs to be replaced, ensuring the long-term stable operation of the system.

[0022] 9) The present invention is applicable to various visual inspection scenarios, whether it is quality inspection in industrial production, measurement experiments in scientific research, or visual inspection needs in other fields, the calibration system can be used for accurate calibration, effectively improving the performance and reliability of the visual inspection system.
