Abstract: A device for measuring a temperature of a heat pipe includes at least one measuring assembly, a block and at least one base. The measuring assembly includes a resilient member with one end thereof mounted on the base, a supporting member coupled to the other end of the resilient member, and a thermocouple arranged on the supporting member. The block defines a through hole configured for receiving the heat pipe inserted therein, and at least one opening in communication with the through hole. The at least one opening is configured for receiving the corresponding at least one measuring assembly. The device can improve the accuracy of temperature measuring of the outer surface of the heat pipe.

Abstract: A lens tray positioning apparatus includes a supporting member, at least three non-collinear positioning members and at least one guiding screw member. The supporting member includes a supporting surface and at least one slot defined in the support surface. The at least three non-collinear positioning members are arranged on the supporting surface and include at least one movable positioning member. The at least one movable positioning member is coupled to and threadedly movable relative to the at least one guiding screw member. The at least one guiding screw member is arranged in the at least one slot and is configured for driving the at least one movable positioning member to move. The at least three positioning members are configured for cooperatively retaining a lens tray in position.

Abstract: An apparatus for assembling lenses includes a lens tray, a support and a tray-securing member. The lens tray defines a plurality of lens-receiving holes configured for receiving lenses and a plurality of positioning holes defined therein. The support is configured for supporting the lens tray and defines a plurality of positioning pins thereon configured for extending through the corresponding positioning holes of the lens tray. The tray-securing member includes a pressing portion defining a through hole therein and a plurality of sleeves configured for receiving the positioning pins therein. The pressing portion is configured for downwardly pressing the lens tray to prevent the lens tray from shaking.

Abstract: An apparatus (50) for removing a plurality of optical elements includes a plurality of clamping device (52) and a connecting portion (54). Each clamping device includes two operating portions (56). Each operating portion has an end portion (58) bent outwardly. The connecting portion is attached to an end opposite to the end portion of each of the clamping devices.
