Abstract:
A lens module testing device includes a base substrate, a supporting assembly, a bearing assembly, a receiving element, and an operation element. The supporting assembly is positioned on the base substrate and includes two supporting plates parallel with each other. One of the supporting plates defines an arc shaped slot. The bearing assembly is rotatably received between the two supporting plates. The receiving element is positioned on the bearing assembly and configured for receiving a lens module. The operation element penetrates the slot and connects to the bearing assembly; the bearing assembly is driven by the operation element to move along the slot and thereby adjusting the angle of the lens module which is presented to a light source.
Abstract:
A protection film includes a base film, a layer of adhesive, and a partition film. The base film includes a main portion and a handle portion extending from a periphery of the main portion. The main portion and the handle portion include a pair of opposite first surfaces. The adhesive is uniformly coated on one of the first surfaces. The adhesive is continuously coated on the main portion and the handle portion. The partition film includes a pair of opposite second surfaces. One of the second surfaces is adhered to a portion of the adhesive coated on the handle portion.
Abstract:
A testing device includes a testing platform, a testing light source, a cover plate, a control circuit board, a probe and an adapter circuit board. The testing platform defines a receiving portion. The testing light source is positioned on the testing platform and opposite to the receiving portion. The cover plate is rotatably connected to the testing platform. The control circuit board is positioned on the testing platform. The probe and the adapter circuit board are positioned on the cover plate. The adapter circuit board is electrically connecting the probe to the control circuit board.
