Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] Such as Figure 1-3 shown.
[0016] A mobile phone display FPC automatic lighting detection device after reflexion, which includes product vacuum positioning platform 1, CCD positioning camera 2 and XYθ adjustment platform 3, such as figure 1 As shown, the XYθ adjustment platform 3 is a standard part, which can be purchased from the market. The CCD positioning camera 2 is also a commercially available product. Its main function is to capture the position of the test point on the FPC connection and adjust the XYθ adjustment platform 3. Provide a basis to ensure that the crimping unit 13 (the same as the existing crimping unit for side testing) contacts the test point correctly, and ensure that each normal detection point can be powered on and lighted up, and displayed correctly on the display 16. The XYθ adjustment platform 3 is installed On the...

The invention discloses an automatic lightening detection device for a mobile phone display screen after FPC reverse folding. The device is characterized by comprising a product vacuumizing positioning platform, a CCD positioning camera and an XYtheta adjusting platform, the X-Y-theta adjusting platform is installed on the bottom plate, the product vacuumizing positioning platform is installed onthe movable support, the movable support is installed on the X-Y-theta adjusting platform, the CCD positioning camera is installed on the fixed support, and the fixed support is fixedly installed on the bottom plate. Two vertical guide rails are installed on the fixing support, and guide rail sliding blocks are installed at the lower ends of the vertical guide rails and installed on horizontal guide rails. A vertical guide rail sliding block on the vertical guide rail is driven by a crimping cylinder; the crimping cross beam is erected on the two vertical guide rail sliding blocks on the two sides, the crimping unit is installed on the crimping cross beam, an adsorption head used for conducting vacuum adsorption on a product and long and short edge positioning blocks are installed on the product vacuum adsorption positioning platform, and the adsorption head is communicated with a vacuum generator. The structure is ingenious, the test is stable, and the test success rate can be greatlyimproved.
Description
technical field [0001] The invention relates to a light-on crimping technology after FPC is folded back, in particular to an electrical connection detection technology of a display screen, in particular to a lighting detection device for a mobile phone display screen after FPC is folded back. Background technique [0002] At present, the electrical connection detection of the mobile phone display screen is to detect the extension of the folded FPC terminal by transferring the FPC. damage, causing display defects, and ultimately affecting the quality of the product. Therefore, if the FPC can be directly crimped and lit after folding, the above defects can be overcome, the waste of consumables can be reduced, the corresponding manpower can be saved, and the yield rate of the product can be improved. The detection equipment for crimping and lighting detection can well overcome the problems existing in the existing FPC detection after reflexion. Contents of the invention [...
