[0002] After the laptops are assembled on the assembly line, they need to be fully tested, during which a wear detection machine will be used to sample and test the laptops. The wear detection machine continuously controls the flipping of the laptop screen, allowing the laptop screen to open and close continuously, to detect the wear of the laptop hinges.

[0003] However, under the preset program, the existing opening and closing detection machine has the same opening and closing speed for the laptop screen each time. The opening and closing speed cannot be adjusted unless the program is controlled. In actual use, the speed at which a person opens the laptop screen is different each time. Therefore, the laptop opening and closing test machine lacks a mechanism that can change the speed to perform opening and closing detection on the laptop screen, and thus the test cannot be close to the actual usage, which reduces the accuracy of the test mechanism. Each time the opening and closing speed is adjusted, the drive parameters need to be adjusted, which makes the adjustment control too cumbersome. Summary of the invention

[0014] 1. A testing machine for detecting the opening and closing wear of a laptop computer is provided with a speed adjustment driving component group and an intermittent adjustment component group. It is necessary to detect the opening and closing of the notebook body in the main component group, mainly by driving the rotation of the movable clamping wall. The movable clamping wall can drive the notebook body to flip the cover. The side frame of the main body is connected to the bottom frame of the main body through a connecting rod. The movable clamping wall is connected to the connecting rod between the bottom frame of the main body and the side frame of the main body through a bearing. In this technology, by starting the servo motor in the speed adjustment driving component group, the servo motor starts the working end to drive the driving horizontal axis to rotate through the synchronous belt assembly. The synchronous belt assembly includes two synchronous gears and a synchronous belt. The synchronous belt is sleeved on the two synchronous gears and is used to connect the two synchronous gears. The two ends of the driving horizontal axis are installed on the bottom frame of the main body through end bracket 1 and end bracket 2. The rotation of the driving horizontal axis will drive the bolt part 1, the adjustment cylinder, the small cross bar, the moving sleeve, the connecting rod, the small gear and the ring frame to rotate. The rotation of the small gear is to rotate around the axis of the driving horizontal axis. The elastic synchronous belt is connected between the small gear and the gear 1.

The movable clamping wall 14 can drive the notebook body 11 to flip the cover. The main body side frame 13 is connected to the main body bottom frame 15 through a connecting rod. The movable clamping wall 14 is connected to the connecting rod between the main body bottom frame 15 and the main body side frame 13 through a bearing. In this technology, the servo motor 21 in the driving component group 02 is started by adjusting the speed. The servo motor 21 starts the working end and drives the driving horizontal axis 23 to rotate through the synchronous belt assembly 22. The synchronous belt assembly 22 includes two The synchronous belt is sleeved on the two synchronous gears to connect the two synchronous gears. The two ends of the driving transverse shaft 23 are installed on the bottom frame 15 of the main body through the end bracket 1 24 and the end bracket 25.

The rotation of the small gear 27 is around the axis of the driving transverse shaft 23. The elastic synchronous belt 210 is connected between the small gear 27 and the gear 1 211. The rotation of the small gear 27 is driven by the elastic synchronous belt 210.

When the opening and closing speed needs to be adjusted, the servo motor 21 is turned off, and the bolt 214 is removed from the driving horizontal shaft 23 and the adjustment cylinder 213. After removal, the position of the adjustment cylinder 213 on the driving horizontal shaft 23 is adjusted and moved. The adjustment cylinder 213 drives the small cross bar 212 and the moving sleeve 29 to move. The movement of the moving sleeve 29 drives the small gear 27 to move through the connecting rod 28, so that the small gear 27 and the driving horizontal shaft 23 can be moved.
