[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] A program can quickly replace the LCD module automatic test device, such as Figure 1-5 As shown, it includes an overall assembly 100, and the overall assembly 100 includes a fixing frame 110, a test transport assembly 200 is fixedly connected to one side of the fixing frame 110, and a jacking assembly 300 is fixedly connected inside the test transport assembly 200;

[0029] The test transport assembly 200 includes a fixed base 210 fixedly connected to one side of the fixed frame 110, fixed grooves 220 are fixedly connected to both sides of the upper end of the fixed base 210, threaded rods 230 are fixedly connected inside the fixed grooves 220, and two groups of moving blocks 240 are sleeved on the outer surface of the threaded rods 230, the upper end of the moving blocks 240 is fixedly connected to a moving frame 250, the upper end of the moving frame 250 is fixedly connected to an electric push rod 260, the lower end of the electric push rod 260 is fixedly connected to a piston plate 280, and the outer surface of the piston plate 280 is sleeved with a moving detection device 270.

[0030] The staff puts the material to be tested above the untested placement block 380, and then starts the motor 2920 to drive the hinge 2930 to rotate, drive the threaded rod 230 to rotate, and at the same time the moving block 240 moves, and at the same time the moving frame 250 moves together. When the moving frame 250 moves to the top of the untested placement block 380, the staff starts the electric push rod 260, and at the same time the piston plate 280 moves downward while squeezing the air inside the mobile detection device 270, so that the sliding rod 290 moves to both sides, and at the same time the clamping plate 2910 moves together, until the sliding rod 290 moves to the specified position, the mobile detection device 270 starts to move downward, and when the mobile detection device 270 moves to the specified position, The electric push rod 260 begins to retract, and the sliding rod 290 will also retract under the negative pressure state. At this time, the clamping plate 2910 clamps the material to the upper end of the test platform 120, and then begins to descend. After descending to the specified position, the test begins. When the test is completed, the material is clamped above the test completion placement block 360 and begins to descend. When the material is placed above the test completion placement block 360, the moving frame 250 begins to move to one side. At this time, the staff can take the material away. This will greatly increase the safety of the staff at work, and can effectively avoid the occurrence of work-related accidents among the staff. At the same time, it will also greatly improve the work efficiency of the equipment.

[0031] Please refer to Figure 3 and Figure 4 The lifting assembly 300 includes a connecting plate 310 fixedly connected to both sides of the moving frame 250, and telescopic cylinders 320 are fixedly connected to both sides of the lower end of the connecting plate 310, and a gas pipeline 330 is fixedly connected to one side of the telescopic cylinder 320. The end of the gas pipeline 330 away from the telescopic cylinder 320 is fixedly connected to a fixed block 331, and the upper end of the fixed base 210 is fixedly connected to the test platform 120. A motor 2920 is provided inside the fixed frame 110, and a hinge 2930 is fixedly connected to the output shaft of the motor 2920.

[0032] When the moving frame 250 moves toward the undetected placement block 380, the connecting plate 310 moves together, and the connecting plate 310 squeezes the telescopic cylinder 320 on one side. At this time, the air in the telescopic cylinder 320 is transmitted to the inside of the fixed block 331 through the air pipeline 330, and the sliding block 350 is lifted up. At this time, the staff can take away the materials that have been detected, which will greatly improve the working efficiency of the equipment.

[0033] Please refer to Figure 1 , Figure 2 and Figure 5The outer surface of the fixed block 331 is sleeved with a sliding block 350, the outer surface of the sliding block 350 is sleeved with a detection completion placement block 360, the other side of the telescopic cylinder 320 is fixedly connected to a connecting pipe 340, the end of the connecting pipe 340 away from the telescopic cylinder 320 is fixedly connected to a fixed cylinder 341, the outer surface of the fixed cylinder 341 is sleeved with a movable sleeve 370, and the outer surface of the movable sleeve 370 is sleeved with an undetected placement block 380.

[0034] When the connecting plate 310 moves to the other side, the air inside the telescopic cylinder 320 will enter the interior of the fixed cylinder 341 through the connecting pipe 340 and lift up the movable sleeve 370. At this time, the staff will place the material on the upper end of the movable sleeve 370, which will greatly improve the work efficiency of the staff.

[0036] The clamping plate 2910 can more conveniently transport materials, thereby greatly improving the working efficiency of the equipment.

[0037] When in use, the staff places the material to be detected above the undetected placement block 380, and then starts the motor 2920 to drive the hinge 2930 to rotate, drive the threaded rod 230 to rotate, and at the same time the moving block 240 moves, and at the same time the moving frame 250 moves together. When the moving frame 250 moves to the top of the undetected placement block 380, the staff starts the electric push rod 260, and at the same time the piston plate 280 moves downward while squeezing the air inside the mobile detection device 270, so that the sliding rod 290 moves to both sides, and at the same time the clamping plate 2910 moves together. After the sliding rod 290 moves to the specified position, the mobile detection device 270 starts to move downward.

After the detection is completed, the material is clamped above the detection completion placement block 360 and begins to descend. When the material is placed on the detection completion placement block 360 After the upper part, the moving frame 250 starts to move to one side, and the staff can take the material away at this time, which will greatly increase the safety of the staff at work, can effectively avoid the occurrence of work-related accidents of the staff, and will also greatly improve the working efficiency of the equipment. When the moving frame 250 moves to the undetected placement block 380, the connecting plate 310 moves together at the same time, and the connecting plate 310 squeezes the telescopic cylinder 320 on one side. At this time, the air in the telescopic cylinder 320 is transmitted to the inside of the fixed block 331 by the air transmission pipeline 330, and the sliding block 350 is lifted up. At this time, the staff can take away the material that has been detected, which will greatly improve the working efficiency of the equipment. When the connecting plate 310 moves to the other side, the air inside the telescopic cylinder 320 will enter the inside of the fixed cylinder 341 through the connecting pipeline 340 and lift the movable sleeve 370 at the same time. At this time, the staff will place the material on the upper end of the movable sleeve 370, which will greatly improve the working efficiency of the staff. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
