[0030] like Figures 1 to 9 As shown, the visual inspection equipment for the light panel of this utility model includes: a feeding mechanism 1, an inspection mechanism 2, and a flipping mechanism 3.

[0031] The feeding mechanism 1 delivers the light panel to the flow line 4. The detection mechanism 2 detects the front side of the light panel. After the detection is completed, the flipping mechanism 3 flips the light panel. The detection mechanism 2 then detects the back side of the light panel. The system is highly automated and does not require manual intervention.

[0032] It should be noted that there are two detection mechanisms 2, one upstream of the flipping mechanism 3 and the other downstream of the flipping mechanism 3. They operate on the same principle and will not be described separately in this application.

[0033] The detection mechanism 2 includes: a bracket 5, a linear module 6 fixedly mounted on the bracket 5, a movable frame 7 mounted on the movable plate of the linear module 6, a camera 8 fixedly mounted on the movable frame 7, and a fill light 9; the linear module 6 moves the camera 8 through the movable frame 7 to take pictures of the light panel, and two fill lights 9 are provided to provide supplementary lighting to the light panel from both sides; the linear module 6 is a common lead screw linear module 6.

[0034] The flipping mechanism 3 includes a flipping motor, the output shaft of which is connected to a rotating shaft 10 via a coaxial reducer. A rotating plate 11 is fixedly installed on the rotating shaft 10. When the lamp panel moves onto the rotating plate 11, the flipping motor drives the rotating plate 11 to rotate, thereby flipping the lamp panel. A protective plate 12 is installed on the flow line 4 to prevent the lamp panel from falling during the flipping process.

[0035] The feeding mechanism 1 includes: a fixed frame 13, a production line 14 is installed on the lower layer of the fixed frame 13, and a pusher plate 15 is provided on the upper layer of the fixed frame 13; a lifting assembly is provided at the end of the production line 14, and a pushing assembly is provided on the side of the fixed frame 13; the light panel is installed in the material frame 16 and moves to the lifting assembly with the production line 14, the lifting assembly drives the material frame 16 to move upward, and the pushing assembly pushes the light panel out of the material frame 16.

[0036] The lifting assembly includes a lifting motor 17, a lead screw 18, a moving seat 19, and a material seat 20. The lifting motor 17 is connected to the lead screw 18, and the lead screw 18 is connected to the moving seat 19 via a slider, so that the lifting motor 17 can drive the moving seat 19 to move up and down through the lead screw 18. The material seat 20 is L-shaped, with its bottom supporting the material frame 16 and its sides abutting against the material frame 16.

[0037] The pushing assembly includes a pushing cylinder 21 and a pushing rod 22. The pushing rod 22 is connected to the piston rod of the pushing cylinder 21. The pushing cylinder 21 drives the pushing rod 22 to move and push out the light panel inside the material frame 16.

[0038] As a supplement, the material frame 16 is provided with multiple material slots inside, and the light panel is inserted into the material slots.

[0039] A fixing plate 23 is installed at the end of the lead screw 18, and the lead screw 18 fixing seat is fixedly installed on the fixing plate 23. A support rod is fixedly installed on the fixing plate 23, and a push cylinder 24 is fixedly installed on the fixing plate 23. A push rod 25 is fixedly installed on the piston rod of the push cylinder 24. When the push cylinder 24 drives the push rod 25 to move, it can push the material frame 16 into the return plate 15 to realize the return of the material frame 16.

[0040] A contact plate 26 is fixedly installed on one side of the fixing frame 13, and an adjusting rod 27 is connected to one side of the fixing frame 13. By adjusting the distance between the adjusting rod 27 and the contact plate 26, the material frame 16 can be made to contact the adjusting rod 27 and the contact plate 26, so that it is stabilized on the material seat 20.

[0041] Specifically: a guide rod 28 is fixedly connected to the end of the adjusting rod 27, and a clamp 29 is fixedly connected to the fixing frame 13. The guide rod 28 is inserted into the clamp 29, and the guide rod 28 is fixed by the clamp 29.

[0042] A mounting plate 30 is fixedly connected to the push plate 15, and a moving rod 31 is movably connected to the mounting plate 30. An elastic element, preferably a spring, is sleeved on the moving rod 31. A guide plate 32 is fixedly connected to the end of the moving rod 31, and a guide wheel 33 is rotatably connected to the guide plate 32. When the lifting assembly drives the material frame 16 to move upward, the guide wheel 33 will abut against the side wall of the material frame 16, so that the side wall of the material frame 16 contacts the side of the material seat 20, thereby providing stable support for the material frame 16.

[0043] Working principle:

[0044] The light panel is installed inside the material frame 16 and moves to the lifting assembly along the production line 14. The lifting assembly drives the material frame 16 to move upward. The pushing cylinder 21 drives the pushing rod 22 to move, pushing the light panel inside the material frame 16 out. At this time, the guide wheel 33 will abut against the side wall of the material frame 16, so that the side wall of the material frame 16 contacts the side of the material seat 20, thereby providing stable support for the material frame 16. When all the light panels are pushed out, the pushing cylinder 24 drives the pushing rod 25 to move, which can push the material frame 16 into the return plate 15, realizing the return of the material frame 16.
