Automatic dome tester for regulating the tension of metal dome

摘要

The sheet having the metal dome of each mobile phone of the present invention is mounted on the dome assembly, and the metal dome is pressed by detecting a load of the metal dome according to the tension value, and whether the dome and the PCB pattern are contacted or separated by the microcomputer. The present invention relates to a tension inspection apparatus for a metal dome having an acceptable tension of quality as a result of inspection and determination of good and defective products. The mobile phone testing apparatus according to the present invention, in the testing apparatus, includes a base frame 10 and a respective mobile phone. A test slide board 30 capable of placing the button sheet s on a PCB pattern, a dome assembly 40 capable of applying pressure to the metal dome d of the button sheet s, and the dome A drive interface 230 for interfacing the tension dome of the metal dome (d) exiting the assembly 40, an air tool kit 50 fixed at an upper position of the dome assembly 40, and the dome Control panel 20 for controlling the allowable pressure for the position of the assembly 40, the pressure sensor 250 for detecting the contact pressure of the metal dome (d), and the electrical connection with the control panel 20 In order to determine the allowable tension or elastic force by the microcomputer 210, the controller 260 adjusts the allowable pressure value through the contact or separation state of the metal dome d, and the control command of the microcomputer 210 is controlled. At least one first air cylinder which receives and provides a predetermined pressure for each position corresponding to the mobile phone metal dome (d) seated between the LCD monitor 60 indicating the driving state of the contact pressure and the air toolkit 50; 270 and the first air cylinder 270 is connected with the rated load on the end of the piston rod so as to be operated by pressing the metal dome (d) to check whether the dome is pressed, The metal dome (d) to the sheet (s) Site missing is provided with at least one second cylinder (270a) having an upside down state and a pin (270x) for the contact position for detecting the state of paste.;Dome Assembly, Air Cylinder, Metal Dome
