Two drive cylinders are mounted on the device body, located below the bending platform. A bending plate is mounted on the bending platform, horizontally positioned and hinged to the bending platform via a rotary shaft. An L-shaped connecting plate is also connected to the bending plate; the horizontal section of the connecting plate is fixed to the bending plate, and the vertical section of the connecting plate is hinged to one end of a connecting rod, while the other end of the connecting rod is hinged to the output shaft of the drive cylinder.
[0006] In the aforementioned automatic bending device for the front frame of a laptop computer, two drive cylinders are located on both sides of two rotary cylinders, and the output shafts of the drive cylinders are horizontally set.
[0007] In the aforementioned automatic bending device for the front frame of a laptop computer, two arc-shaped grooves are installed between two bending plates, with the openings of the arc-shaped grooves facing upwards. One arc-shaped groove is located on one side of a rotary cylinder, and the other arc-shaped groove is located on one side of another rotary cylinder.
[0008] In the aforementioned automatic bending device for the front frame of a laptop computer, a control panel is installed on the device body. The control panel and the controller are electrically connected, and the solenoid valves of the rotary cylinder and the drive cylinder are both electrically connected to the controller.
[0009] In the aforementioned automatic bending device for the front frame of a laptop computer, a limiting plate is provided on the bending plate, and the front frame of the laptop computer abuts against the limiting plate.
[0010] Compared with existing technologies, this invention can stably bend the front frame of a laptop computer, thereby testing the bending resistance of the laptop computer's front frame. Attached Figure Description
