[0021] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] A backlight module detection device for display screen production includes a base 1, and a detection component 3 is fixed directly above the base 1 through a bracket 2:

[0023] A circular seat 4 driven by a motor 15 is provided above the base 1. Multiple groups of accommodating units 6 are provided circumferentially on the circular seat 4, one of which is located directly below the detection component 3. A driving mechanism 7 for driving the corresponding accommodating unit 6 to move up and down is provided on the base 1 directly below the detection component 3.

[0024] The accommodating unit 6 includes a rectangular groove 61 arranged at the top of the circular seat 4, a polygonal mounting hole 62 is provided at the bottom of the rectangular groove 61, a vertical tube 63 adapted thereto is provided in the mounting hole 62, a circular ring 64 is provided on the bottom of the vertical tube 63 and located below the circular seat 4, a spring 65 is provided on the vertical tube 63 above the circular ring 64, a convex seat 66 is provided below the circular ring 64, a square hole 67 is provided at the bottom of the convex seat 66, a rotating shaft 68 is provided on the top of the convex seat 66, which passes through the vertical tube 63 and is connected to the fixed seat 69 in the rectangular groove 61, the size of the fixed seat 69 is adapted to the size of the rectangular groove 61, and the top of the fixed seat 69 extends to the outside of the top of the rectangular groove 61;

[0025] The driving mechanism 7 includes a hydraulic rod 71 , a motor II 72 is provided on the top of the output shaft of the hydraulic rod 71 , and a driving block 73 that can be inserted into the corresponding square hole 67 is provided on the output shaft of the motor II 72 .

[0026] like Figure 2 、 3As shown, the size of the driving block 73 is adapted to the size of the square hole 67 , the top corners of the driving block 73 are provided with rounded corners, and a circle of support portions 8 is provided around the driving block 73 .

[0027] In this embodiment, a mounting seat 9 is provided on the top of the base 1, and a mounting cavity for accommodating the motor 15 is provided in the mounting seat 9.

[0028] The detection component 3 includes an electric push rod 31 horizontally arranged on one side of the frame 2, a slide 32 is provided on the output shaft of the electric push rod 31, a detection lens 33 is provided at the bottom of the slide 32 and is located directly above one group of fixed seats 69, and a slide rod 34 is also provided on the frame 2 and passes through the through hole on the slide 33.

[0029] The cross-section of the internal opening of the vertical tube 63 is circular, the top of the vertical tube 63 is located in the mounting hole 62, the bottom end of the vertical tube 63 is fixedly connected to the circular ring 64, and the top of the boss 66 is evenly provided with a receiving groove with a cross-section of a major arc. The receiving groove is provided with a ball 10 with one end extending to the outside thereof to abut against the bottom end surface of the corresponding circular ring 64.

[0030] When in use, the backlight module is fixed on the fixing seat 69, wherein the motor I5 drives the circular seat 4 to rotate, and then sequentially places the backlight module on multiple sets of fixing seats 69, wherein the rotating circular seat 4 drives the corresponding fixing seat 69 and the backlight module to move to the bottom of the detection component 3. At this time, Figure 2 、 3 As shown, the driving block 73 is aligned with the square hole 67 directly above it, so the hydraulic rod 71 drives the motor II72 to drive the driving block 73 to be well inserted into the square hole 67 directly above it, without the problem that the driving block 73 and the square hole 67 are misaligned and cannot slide into the square hole 67. Then, the protrusion 66 is lifted up to push the shaft 68 to drive the fixing seat 69 and the backlight module above it to move upward, thereby making the backlight module on the fixing seat 69 close to the detection lens 33, so that the detection lens 33 can more conveniently and better detect the backlight module. In the process of the protrusion 66 moving upward, the vertical tube 63 is driven to move upward through the ring 64 while squeezing the spring 65.

[0031] In the above process, the electric push rod 31 can drive the slide 32 to drive the detection lens 33 to move horizontally left and right to cover several areas on the straight line formed between the left and right ends of the backlight module on the fixed seat 69. At the same time, the motor II72 drives the corresponding backlight module to rotate through the driving block 73, the protruding seat 66, the rotating shaft 68 and the fixed seat 69. Finally, the motor II72 will drive the fixed seat 69 to reset to face the rectangular groove 61 through the above components, so that the fixed seat 69 can slide into the rectangular groove 61 when it moves down, so that the above method can be used to achieve The left-right displacement detection lens 33 can detect the backlight module in different directions and angles. When the boss 66 and the rotating shaft 68 rotate, they drive the ball 10 to rotate in the receiving groove. The rotating shaft 68 rotates in the vertical tube 63. The polygonal mounting hole 62 blocks the vertical tube 63 to prevent it from rotating with the rotating shaft 68, while not affecting the rotation of the rotating shaft 68. Ultimately, the vertical tube 63 and the spring 65 will not rotate with the rotating shaft 68. Therefore, the spring 65 will not be compressed and then rotated, causing it to twist violently.

[0032] When the inspection is completed, the hydraulic rod 71 drives the motor II72 and the drive block 73 to move downward and finally withdraw from the square hole 67. At this time, the spring 65 stretches the drive ring 64 to squeeze the convex seat 66 downward, and the convex seat 66 drives the fixed seat 69 to move down into the rectangular groove 61 through the rotating shaft 68. In this process, due to the way that the drive block 73 clamps the side wall of the square hole 67, the convex seat 66, the round rod 68 and the fixed seat 69 will not rotate during the downward movement, so that the fixed seat 69 can slide smoothly into the rectangular groove 61. At the same time, the circular seat 4 rotates to drive the backlight module to be inspected on the next group of fixed seats 69 to be moved to the bottom of the inspection component 3 for inspection. People remove the backlight module rotated out of the accommodating unit 6 from the inspection component 3 and put in a new product to be processed. The above steps can be repeated to realize streamlined production work, so that there is always a product for inspection directly below the inspection component 3, and the inspection component 3 will not be idle due to the removal and placement of the backlight module on the accommodating unit 6, thereby affecting the processing efficiency.

[0033] The present invention has been described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
