[0005] A detection device for keyboard production includes a detection machine, a placement plate, a lifting frame, a fixed plate, a mounting plate, a contact plate, a guide rod, a reset spring and a detection component. A placement plate is installed in the middle of the detection machine, and a lifting frame is slidably connected to the middle of the detection machine. The detection machine can control the lifting frame to move back and forth. The lifting frame is above the placement plate, and a detection component for pressing keyboard keys is installed on the bottom of the lifting frame. The top front and left sides of the placement plate are connected to the fixed plates by bolts, and the two fixed plates are perpendicular to each other. The top rear side of the placement plate is connected to the mounting plate, and four guide rods are slidably connected to the mounting plate. The front ends of the four guide rods are connected to the same contact plate. A reset spring is connected between the contact plate and the mounting plate, and the reset spring is wound around the outside of the guide rod.

[0006] Further explanation: the detection component includes a pressure plate, an airbag, an air intake pipe and a sealing cover. The bottom of the lifting frame is connected to a pressure plate, an airbag is provided on the bottom of the pressure plate, an air intake pipe is connected to the pressure plate, the air intake pipe is connected to the airbag, and a sealing cover is installed at the air inlet of the air intake pipe.

[0007] Further description also includes foam pads, which are provided on the fixing plate and the contact plate. The foam pads play a protective role and prevent wear and tear on the keyboard surface.

[0008] Further explanation: There is also a pressure display on the side of the airbag. The pressure display can display the air pressure inside the airbag, making it convenient for people to inflate the airbag accurately.

[0009] Further explanation: there is also a winding rack. There is a winding rack on the right side of the top of the placement board. The winding rack can wind and organize the data cable to facilitate people to test the keyboard.

[0010] Further explanation includes threaded holes, and the left side and front side of the top of the placement plate are both provided with threaded holes in a rectangular array.

[0011] The beneficial effects of the present invention are as follows: the present invention drives the lifting frame to move back and forth up and down through the detection machine, thereby driving the pressure plate and the airbag to move back and forth, thereby pressing the keyboard keys.
