[0048] The following is combined with Figures 1 to 12 The utility model is described in further detail.

[0049] Reference Figures 1 to 12 As shown, the fully automatic detection and packaging equipment for shielding covers provided by the embodiment of the utility model includes a frame 100, a feeding device 200, a crack detection device 300, an appearance detection device 400, a flatness detection mechanism 500 and a packaging device 600. The feeding device 200 is arranged on one side of the frame 100. The feeding device 200 includes a vibration plate 210 and a CCD detection component 220. A pulse electromagnet is arranged below the vibration plate 210, which can make the vibration plate 210 hopper vibrate in a vertical direction, and the spring sheet in the vibration plate 210 drives the hopper to perform torsional pendulum vibration around its vertical axis. The parts in the hopper rise along the conveying track of the vibration plate 210 due to such vibration. During the rising process, after a series of track screening or posture changes, the shielding cover 800 can be automatically fed in a unified state according to the processing requirements, that is, the vibration plate 210 can automatically and orderly arrange the disorderly placed shielding covers 800 and accurately convey them to the next process. The CCD detection assembly 220 is installed above the vibration plate 210, and performs direction detection on the shielding cover 800 transported by the vibration plate 210, and feeds back the detected result to the vibration plate 210 in real time. The crack detection device 300 is located at the output end of the feeding device 200, and the crack detection device 300 is used to detect cracks on the outer surface of the shielding cover 800. The feeding device 200 can automatically feed the shielding cover 800, and the automatically fed shielding cover 800 can be arranged in a certain posture direction.

The entire feeding process does not require manual participation, and the whole process is automatic, which speeds up production efficiency.

[0050] It is understandable that, referring to Figure 1 , Figure 2 and Figure 6As shown, the appearance inspection device 400 is provided with a first turntable assembly 410 and a visual inspection assembly 420. The first turntable assembly 410 includes a rotary driver 411, a fixed seat 412, a mounting fixture 413 and a turntable 414.

The turntable 414 rotates intermittently under the drive of the rotary driver 411. The mounting fixture 413 can be installed with multiple shielding covers 800 to perform the next appearance inspection on the shielding covers 800. The mounting fixture 413 is fixed on the upper surface of the turntable 414 and is located at the edge. There are multiple mounting fixtures 413, and the multiple mounting fixtures 413 are arranged circumferentially along the turntable 414. The visual inspection assembly 420 includes a first inspection assembly 421, a second inspection assembly 422 and a third inspection assembly 423.

The annular light source 424 can provide different illumination angles and different color combinations for the shielding cover 800, highlight the three-dimensional information of the shielding cover 800, and facilitate the detection of surface damage of the shielding cover 800. The annular light source 424 and the detection camera 313 are divided into two groups, one group of annular light sources 424 and the detection camera 313 are located above the turntable 414 to perform appearance inspection on the upper surface of the shielding cover 800 in the installation fixture 413, and the other group of annular light sources 424 and the detection camera 313 are located below the turntable 414 to perform appearance inspection on the lower surface of the shielding cover 800 in the installation fixture 413. The second detection component 422 includes a coaxial light source 425 and a detection camera 313.
