The invention provides a lens looseness testing device and method. The lens looseness testing device comprises a rack, a testing module fixedly arranged on the rack, and a testing graph card fixedly arranged on the rack and adjacent to the testing module. The test module comprises a base fixedly arranged on the rack, a rotary driving part fixedly arranged on the base, a rotary bracket which is connected with the rotary driving part and is driven by the rotary driving part to rotate, a knocking assembly fixedly arranged on the rotary bracket, an imaging assembly fixedly arranged on the rotary bracket and a fixing assembly fixedly arranged on the rotary bracket; the knocking assembly and the fixing assembly are arranged adjacent to the imaging assembly; the fixing assembly is used for fixing a to-be-tested lens to enable the to-be-tested lens to be located at the top of the imaging assembly, the knocking assembly is used for knocking the to-be-tested lens, and the imaging assembly is used for collecting an image of a test graphic card through the to-be-tested lens and judging whether the to-be-tested lens is loosened based on the image. Whether the lens is loosened or not can be accurately detected.

    本发明提供了镜头松动测试装置及方法。其中镜头松动测试装置包括机架、固定设于机架的测试模块、以及固定设于机架且邻近测试模块的测试图卡,测试模块包括固定设于机架的底座、固定设于底座的旋转驱动件、与旋转驱动件连接并由旋转驱动件驱动进行旋转运动的旋转支架、固定设于旋转支架的敲击组件、固定设于旋转支架的成像组件以及固定设于旋转支架的固定组件,敲击组件以及固定组件邻近成像组件设置;固定组件用于固定待测镜头使待测镜头位于成像组件的顶部,敲击组件用于敲击待测镜头,成像组件用于通过待测镜头采集测试图卡的图像并判断基于图像判断待测镜头是否松动。本发明可以准确地检测镜头是否松动。
