A touch screen test fixture

Abstract

The invention discloses a testing jig for a touch screen. The testing jig comprises a texting box with an opening on the top and a testing circuit board in the testing box, wherein a lower template is arranged in the opening of the testing box, a machine frame is arranged outside the testing box, an upper template is connected onto the machine frame through a guide rod, an inverted air cylinder is further arranged on the machine frame, an output shaft of the air cylinder is connected with the upper template, and a control panel and a switch handle are arranged in front of the testing box; and according to the circuit board in the testing box independently, a base material plate printed with a circuit, a circuit board hotpressed with an IC (integrated circuit), and a touch screen semi-finished product compressed with a glass panel are subjected to a test, testing can be carried out after each procedure, defective products can be found and removed as early as possible, so that loss caused by flow of defective products into the next procedure is prevented, the production cost is greatly saved, when the test is carried out, a to-be-tested product is placed on the lower template, the upper template is driven to downward moving by starting the air cylinder after the operation of the switch handle, and the to-be-tested product is fixed to carry out the test.

Description

technical field [0001] The invention relates to a special jig for testing the touch screen on the capacitive touch screen production line for mobile phones. Background technique [0002] Touch screen is widely used in various electronic products such as mobile phones, notebook computers, MP3 and MP4, etc. As an input medium, it is currently the simplest, most convenient and natural way of human-computer interaction. At present, the common touch screens on the market can be divided into resistive screens and capacitive screens according to the working principle. Among them, the capacitive screen is called the current mainstream touch screen due to its long life and high light transmittance. [0003] In the production of capacitive touch screens, the base material needs to be connected with the driver IC after printing the circuit, and then hot-pressed onto the circuit board to obtain the FPC with IC, and then pressed on the glass panel to obtain the finished touch screen. In ...

Problems solved by technology

[0003] In the production of capacitive touch screens, the base material needs to be connected with the driver IC after printing the circuit, and then hot-pressed onto the circuit board to obtain the FPC with IC, and then pressed on the glass panel to obtain the finished touch screen. In the above production, the base material Before connecting with the IC and after hot pressing, failures are prone to occur. However, the current touch screen production line is often tested after the finished touch screen is obtained. It is impossible to test the semi-finished product after printing the circuit and after hot pressing the IC. Defective products are found, so production costs are lower
