[0026] In order to facilitate the understanding of the AOI multifunctional detection device of the embodiment one, the following is further explained:

[0027] S1, the bearing table 2 used for detecting the internal and deep defects of the detection object 8 is clamped on the transmission block 7;

[0028] S2, the detection object 8 is placed on the center position of the grid member 21;

[0029] S3, the Y-axis driving unit 4 drives the bearing table 2 to make the bearing table 2 located in the first-level detection area 12; the X-axis driving unit 3 drives the second-level detection camera 32 to make the detection object 8 and the second-level detection camera 32 located in the coaxial position,

[0030] S4, the fourth-level Z-axis driving unit 34 drives the second-level detection camera 32 to take samples from top to bottom for the internal and deep defects of the detection object 8;

[0031] S5, the operator judges by analyzing the related internal pattern transmitted by the sensor;

[0032] S6, if there is no internal and deep defect, the detection object 8 is qualified in this detection, and the detection object 8 is sent to the next detection item;

[0033] S7, if there is internal and deep defect, the detection object 8 is unqualified in this detection, and the related process is adjusted.

[0034] In the embodiment two, different from the embodiment one, there are the following aspects:

[0035] Referring to the drawings Figure 4 As shown in the embodiment two, when detecting the surface defects of the detection object 8, the light-transmitting member 22 is arranged on the center position of the bearing table 2, and the light-transmitting member 22 is made of transparent material, so as to ensure that the back defects of the detection object 8 can be detected, and improve the comprehensiveness of the detection.

[0036] In order to facilitate the understanding of the AOI multifunctional detection device of the embodiment two, the following is further explained under the premise that the use method is unchanged:

[0037] S1, the bearing table 2 used for detecting the surface defects of the detection object 8 is clamped on the transmission block 7;

[0038] S2 places the object to be tested 8 at the center of the light-transmitting element 22;

[0039] S3 instructs the Y-axis drive unit 4 to drive the support stage 2, positioning the support stage 2 within the primary detection area 12; and instructs the X-axis drive unit 3 to drive the primary detection camera 31, positioning the object to be detected 8 and the primary detection camera 31 coaxially.

[0040] S4 instructs the three-stage Z-axis drive unit 33 to drive the first-stage detection camera 31 to perform internal imaging and sampling of the detection object 8 from top to bottom.

[0041] The S5 operator makes a judgment by analyzing the relevant surface patterns transmitted by the sensors;

[0042] If no surface defects are found in S6, then the test item 8 is qualified for this test and will be sent to the next test item.

[0043] If surface defects are found in S7, the test item 8 will fail this test, and the relevant processes will be adjusted.

[0044] In this third embodiment, the differences from embodiments one and two are as follows:

[0045] See appendix Figure 5 As shown in this embodiment three, when performing thickness defect detection on the test object 8, the side end of the support platform 2 is provided with a snap-fit ​​groove 23 extending along the Y-axis. The snap-fit ​​groove 23 is used to snap into the test object 8. The outer dimensions of the snap-fit ​​groove 23 are slightly larger than the outer dimensions of the snap-fit ​​part of the test object 8, so that the test object 8 can be easily snapped into the snap-fit ​​groove 23. This avoids the situation where some test objects 8 cannot be snapped into the snap-fit ​​groove 23 due to size factors, thus improving the adaptability of the equipment. The two sides of the opening of the snap-fit ​​groove 23 are also provided with a part removal part 24, which makes it convenient for the operator to remove the test object 8 that is snapped into the snap-fit ​​groove 23. This avoids the test object 8 shrinking into the snap-fit ​​groove 23, making it impossible for the operator to remove it, thus improving practicality.

[0046] To facilitate understanding of the AOI multifunctional detection device in Embodiment 1, the following further explains the usage method 3, while keeping its usage method unchanged:

[0047] S1 attaches the support platform 2, used to detect thickness defects in the test object 8, to the transmission block 7;

[0048] S2 partially snaps the test object 8 into the snap-fit ​​slot 23;

[0049] S3 instructs the Y-axis drive unit 4 to drive the carrier stage 2, so that the carrier stage 2 is located in the secondary detection area 13;

[0050] S4 makes the movable end of the secondary Z-axis driving unit 6 extend along the Z-axis direction until the movable end is higher than the height position of the clamping groove 23;

[0051] S5 makes the tertiary detection camera 51 emit detection light downward along the Z-axis direction, and makes the Y-axis driving unit 4 drive the bearing table 2 to move along the Y-axis direction;

[0052] S6 moves the bearing table 2 along the Y-axis direction, so that the detection light moves to contact the surface of the detection object 8, and records relevant data;

[0053] S7 until the detection object 8 is stopped by the movable end of the secondary Z-axis driving unit 6, and is retracted into the clamping groove 23;

[0054] S8 the operator makes a judgment by analyzing the relevant data transmitted by the sensor;

[0055] S9 if there is no thickness defect, the detection object 8 passes the detection, and is sent to the next detection item;

[0056] S10 if there is a thickness defect, the detection object 8 fails the detection, and the relevant process is adjusted.
