[0023] Please refer to Figures 1-5 , in the present utility model, an LCM module detection device includes a detection support table 1 and a vision detection mechanism 6. A square bottom box 3 is fixedly connected to the upper surface of the detection support table 1. A dual-axis motor 11 is fixedly connected to the inner bottom wall of the square bottom box 3. Threaded lead screws 12 are fixedly connected to both output ends of the dual-axis motor 11. A screw sleeve ring 13 is threadedly connected to the outer surface of each threaded lead screw 12. A transmission member 17 is fixedly connected to the outer surface of each screw sleeve ring 13. The front end of each transmission member 17 penetrates through the square bottom box 3 and extends to the front of the square bottom box 3. A moving clamping member 18 is fixedly connected to the outer surface of each transmission member 17. A support plate 20 is fixedly connected to the upper surface of each moving clamping member 18. A telescopic cylinder 21 is fixedly connected to the upper surface of each support plate 20. A connecting square rod 22 is fixedly connected to the output end of each telescopic cylinder 21. One end of each connecting square rod 22 penetrates through the moving clamping member 18 and is fixedly connected to a pressing member 23. The operation of the dual-axis motor 11 can drive the threaded lead screw 12 to rotate, so that the threaded lead screw 12 can drive the screw sleeve ring 13 and the transmission member 17 to move closer to each other. Furthermore, the movement of the two moving clamping members 18 can be used to position both sides of the placed LCM module, preventing left and right offsets. By using the telescopic cylinder 21, the connecting square rod 22, and the pressing member 23, the telescopic cylinder 21 can be operated to push the connecting square rod 22 and the pressing member 23 to move up and down. Thus, the movement of the pressing member 23 can be used to limit the top of the LCM module, and the purpose of stably positioning the LCM module to be detected is achieved, ensuring the stability during detection and facilitating the detection.
[0024] A rubber pad 26 is fixedly connected to the outer surface of each moving clamping member 18 and the outer surface of the pressing member 23. A protective pad 2 is fixedly connected to the upper surface of the detection support table 1. The rubber pad 26 and the protective pad 2 provided can play a protective role for the LCM module to be detected, avoiding damage during detection. An L-shaped connecting plate 4 is fixedly connected to the upper surface of the square bottom box 3. An electric cylinder 5 is fixedly installed on the upper surface of the L-shaped connecting plate 4 through a bracket. The output end of the electric cylinder 5 is fixedly connected to the vision detection mechanism 6. The vision detection mechanism 6 is composed of a connecting plate 7, a supplementary light 8, an industrial camera 9, and a lens 10. It is convenient to use the vision detection mechanism 6 to detect the fixed LCM module. The industrial camera 9 is used to replace the human eye to complete functions such as detection, improving the accuracy of detection.
[0025] A guiding groove 19 is provided on the outer surface of each moving clamping member 18, and the connecting square rod 22 is slidably connected to the guiding groove 19. A through square opening 16 adapted to the transmission member 17 is provided on the front surface of the square bottom box 3.

A circular column 14 is fixedly connected to the inner wall of the square bottom box 3. Two square sliding plates 15 are slidably connected to the outer surface of the circular column 14. The outer surface of each square sliding plate 15 is fixedly connected to the upper surface of the screw sleeve ring 13, so that when the screw sleeve ring 13 moves, it drives the square sliding plate 15 to slide on the circular column 14, and at the same time plays a role in strengthening the screw sleeve ring 13, ensuring that the threaded lead screw 12 can drive the screw sleeve ring 13 to move, facilitating adjustment and use. Two guiding slideways 24 are provided on the outer surface of each moving clamping member 18. An auxiliary slide bar 25 is slidably connected to the inside of each guiding slideway 24. The outer surface of each auxiliary slide bar 25 is fixedly connected to the outer surface of the pressing member 23, and it can drive the auxiliary slide bar 25 to slide up and down in the guiding slideway 24 when adjusting the position of the pressing member 23, preventing the pressing member 23 from tilting.
[0026] The working principle of the present utility model is as follows:
[0027] During the use process, the device is firmly installed and powered on. The LCM module to be detected is placed on the protective pad 2. Then, the double-shaft motor 11 is started to operate, driving the two threaded lead screws 12 to rotate. Under the action of the thread, the screw sleeve ring 13 and the transmission member 17 are driven to move, and the transmission member 17 is used to drive the moving clamping member 18 to move, so that the two moving clamping members 18 move closer to each other to clamp both sides of the LCM module. Then, the two telescopic cylinders 21 are started to operate to push the connecting square rod 22 and the pressing member 23 downward. The movement of the pressing member 23 facilitates pressing the top of the LCM module, thereby realizing the fixation of the LCM module. Then, the electric cylinder 5 can be started to push the vision detection mechanism 6 downward to approach the fixed LCM module. The cooperation of the supplementary light 8, the industrial camera 9 and the lens 10 on the vision detection mechanism 6 can detect whether the surface coating is complete, sunken and scratched, etc., improving the detection accuracy and ensuring the stability during the detection process.
