The X-axis movement motor drives the X-axis lead screw, which in turn drives the movement arm 7 along the crossbeam. Both ends of the Y-axis lead screw are mounted on a support base. A slider, threadedly engaged with the Y-axis lead screw, is connected to one end of the crossbeam. The other end of the crossbeam slides with the Y-axis guide rail. The Y-axis movement motor drives the Y-axis lead screw, which in turn drives the crossbeam and movement arm 7 along the Y-axis guide rail. Furthermore, a lifting and rotating mechanism is mounted within the movement arm 7. This mechanism includes a micromotor and a belt drive assembly. The two pulleys of the belt drive assembly are fixed within the movement arm. A vacuum suction cup is fixed to the belt via the micromotor, and the vacuum suction cup is fixed to the end of the micromotor's output shaft. When the detection unit detects that the product on the lower vibration plate is not facing forward or is not oriented correctly, the lifting and rotating mechanism and the vacuum suction cup can be used to align the product's orientation.

[0042] When designing specifically, Figure 1 、 4As shown, the detection unit includes a first detection camera 11, a second detection camera 12, a third detection camera 13, a fourth detection camera 14 and a fifth detection camera 15 connected with the controller, the first detection camera 11 is arranged above the vibrating disc 3 for detecting the front and back of the product and the taking direction; the second detection camera 12, the third detection camera 13 and the fourth detection camera 14 are sequentially arranged along the length direction of the conveying belt, the second detection camera 12 is used for detecting the flatness of the product, the third detection camera 13 and the fourth detection camera 14 are respectively used for detecting the appearance quality of the product; the fifth detection camera 15 is arranged above the packaging station 002 for detecting whether the product in the blister tray 00 is missed.

[0044] In the specific embodiment of the utility model, as shown in Figure 7 、 8As shown, the ends of the first and second conveyor belts 21, 22 are each equipped with a limiting optical fiber 46 that can be linked to the corresponding conveyor motors. When the shielding cover reaches the end, it promptly sends a stop signal to the conveyor motors. Furthermore, limiting baffles 47 are installed on both sides of the first and second conveyor belts 21, 22 to prevent the shielding cover from deviating from the first and second conveyor belts 21, 22 during operation.

[0045] In this embodiment, the electronic product is a shielding cover 01, and the specific installation and inspection process of the second inspection camera 12, the third inspection camera 13, and the fourth inspection camera 14 is as follows:

[0046] like Figure 10 As shown, a transparent storage table 48 for placing electronic products is provided above the second detection camera 12. A positioning cylinder 49 for positioning electronic products is provided on one side of the storage table 48. A detection optical fiber 50 is provided on the opposite side of the positioning cylinder 49. It can detect whether the electronic products on the storage table 48 have been sucked away by the vacuum suction cup at the lower end of the first PPU robot, ensuring that no stacking occurs when the next shielding cover is inspected. The second detection camera 12 is connected to the KK module 51, which is used to drive the second detection camera 12 to move back and forth below the storage table 48 to scan the electronic products on the storage table 48. In the figure, the second detection camera uses a line laser 3D camera, the storage table uses K9 optical glass (the specific size can be determined according to the number of shielding covers to be inspected), and the storage table is connected to the workbench 1 through a support seat 52. The two detection optical fibers 50 are respectively connected to the two ends of the storage table through support rods 54. The movable end of the positioning cylinder 49 is connected to the push plate 53, which fixes the shielding cover on the storage table. Two detection optical fibers are used on both sides of the shielding cover to achieve product positioning. The KK module drives the linear laser 3D camera to scan the upper shielding cover to achieve flatness detection.

[0047] like Figure 11 As shown, a transparent storage platform 48 for placing electronic products is also provided above the third detection camera 13. Four positioning fixtures 56 for positioning electronic products are provided around the storage platform 48. One side of the storage platform 48 is provided with a detection optical fiber 50 for detecting whether the electronic products are stacked. A box 55 is provided at the bottom of the storage platform 48, and the upper and lower openings of the box can be used for the third detection camera 13 to detect from bottom to top, and to detect the paint and appearance of the front of the electronic product. Among them, the positioning fixture adopts a four-jaw chuck commonly used in machine tools (with the same clamping principle as the chuck on the machine tool), which can fix the electronic product. The third detection camera can be installed in the lower cabinet under the workbench, and the workbench is provided with a through hole for the third detection camera to detect.

[0048] like Figure 12As shown, the fourth inspection camera 14 is connected to the workbench via a column 57.

Surrounding the positioning fixture 58 are multiple prisms 59 tilted toward the center bottom, enabling detection of leaks on the outer surface of the electronic products. A fiber optic inspection device 50 is mounted on one side of the platform 48 to detect stacked materials. A housing 55 and a light source 60 are located at the bottom of the fourth inspection camera 14. The fourth inspection camera 14 uses a CCD camera to inspect the front appearance of the product from top to bottom.

[0049] When designing specifically, Figure 1 、 13 As shown, the defective product sorting mechanism includes a push cylinder 23 and a defective product collection box 24. The defective product sorting station 18 is equipped with a positioning platform 25. The movable end of the push cylinder 23 is fixed with an upwardly extending vertical plate, the upper end of which is connected to the positioning platform 25. A guide slot 26 is provided below the positioning platform 25, which is arranged diagonally downward, with the discharge end of the guide slot 26 positioned above the defective product collection box 24. When a defective product is detected, the second PPU robot moves it above the positioning platform 25. The push cylinder 23 is activated to drive the positioning platform 25 backward. The second PPU robot releases the defective product, which falls into the guide slot and slides down into the defective product collection box 24 for collection. If the electronic product passes the test, the second PPU robot moves it onto the positioning platform 25 and positions it using a positioning jig 56. The detection optical fiber 50 verifies whether the electronic product is stacked. The second PPU robot then moves the product to the transfer jig 28 of the transfer mechanism.

[0050] Further optimize the above scheme, such as Figure 1 、 14 As shown, a transfer mechanism is provided between the packaging station 002 and the defective product sorting station 18.
