A first visual inspection camera 10 for detecting the top of the folding LCD screen is fixed on the lower side of the first horizontal plate 9, and a second visual inspection camera 12 for detecting the bottom of the folding LCD screen is fixed on the upper side of the second horizontal plate 11. Through the installation and use of the first visual inspection camera 10 and the second visual inspection camera 12, the two visual inspection cameras are arranged one above and one below to detect the upper and lower surfaces of the folding LCD screen. The model of the visual inspection camera is MV-CA013-A0GM. At the same time, the visual inspection camera can be used to photograph the folding LCD screen and obtain image data for plane inspection so as to detect defects on the surface of the folding LCD screen. Lighting lamps 14 are installed at both ends of the first horizontal plate 9 and the second horizontal plate 11.

[0030] Four universal wheels 16 are installed on the lower side of the cart 15. The universal wheels 16 can be used to move the folding LCD screen on the cart 15 so that the folding LCD screen can be placed in or taken out, saving time and effort. There is no need to repeatedly move the folding LCD screen for photo inspection. A tooling seat 17 is fixedly installed on the upper side of the cart 15. The inside of the tooling seat 17 is installed with an array of folding LCD screen bodies 19. The bottom end of the tooling seat 17 is connected to a rubber round pad 18 for fixing the folding LCD screen body 19. The front side of the cart 15 is fixedly connected to a connecting armrest 22.

[0031] Two symmetrically arranged L-shaped support frames 20 are installed on the inner side of the detection device body 1. The L-shaped support frames 20 can be used to support and fix the entire detection device body 1 to ensure the stability of the detection device body 1. Two symmetrically arranged guide columns 28 are installed on the rear side of the cart 15. The guide columns 28 can be used to position the cart 15 on the detection device body 1 so that the cart 15 can be installed stably. A fixing plate 21 for fixing the guide columns 28 is connected between the two L-shaped support frames 20.

[0032] The inner sides of the two L-shaped support frames 20 are both installed with second U-shaped side panels 24, and the front side of the cart 15 is fixedly connected with two symmetrically arranged first U-shaped side panels 23.

[0035] The working principle of the folding LCD screen detection device provided by the utility model is as follows:

[0036] By utilizing the motor of the electric guide rail 5, the electric slider 6 can be moved on the electric guide rail 5, so that the detection height of the first visual inspection camera 10 at the first horizontal plate 9 and the second visual inspection camera 12 at the second horizontal plate 11 can be adjusted up and down, and then the output shaft of the servo motor 13 drives the double-headed screw rod 2 to rotate so that the two mounting blocks 4 on the double-headed screw rod 2 can move toward each other, so that the first visual inspection camera 10 and the second visual inspection camera 12 can synchronously enter the interior of the tooling seat 17, and at this time, both sides of the folding LCD screen main body 19 can be photographed and inspected, without repeatedly adjusting the position of the LCD screen, reducing labor intensity, and thus improving the inspection efficiency of the folding LCD screen inspection device, and then the electric push rod 8 can be used to further move and adjust the inspection position of the two visual inspection cameras, so as to comprehensively inspect the folding LCD screen and ensure the inspection effect, and at the same time, the lighting lamp 14 can be used to detect and provide a lighting source, so that the photo inspection work is clearer and more reliable;

[0037] The folding LCD screen body 19 is placed into the rubber round pad 18 of the work seat 17 to preliminarily fix the folding LCD screen. Then, the two fastening bolts 31 are rotated respectively to release the limit of the two rubber vertical plates 30 installed with the connecting springs 25. In this way, the two elastic rubber vertical plates 30 can elastically clamp folding LCD screens of different sizes, so that the folding LCD screen can be stably fixed on the cart 15. Then, the universal wheels 16 can be used to drive the two guide columns 28 at the cart 15 to be clamped into the fixed plate 21, and then the two limiting rotary plates 26 are rotated in turn to the two first U-shaped side plates 23, and the two vertical insertion rods 27 are inserted into the limiting rotary plates 26 and the first U-shaped side plates 23 to firmly position all the folding LCD screens on the cart 15, so that the detection work can be carried out safely and stably to prevent the folding LCD screen from shaking.
