    Abstract: A lens module with enhanced absorption of stray light includes a sensor and a mounting bracket. The sensor includes a photosensitive area and a non-photosensitive area arranged surrounding the photosensitive area. The sensor is received in the mounting bracket and a window is defined in the mounting bracket. An annular flange extends from an inner wall of the window towards a center axis of the window. The annular flange includes a reflecting surface facing away from the inner wall of the window and tilted towards the sensor. The photosensitive area is exposed in a through hole of the annular flange. Diffusing reflection structures are formed on the reflecting surface and are configured to diffuse light incident on the non-photosensitive area away from the photosensitive area.

    Abstract: A 3D sensing device includes a base, an infrared emitting module, a first infrared receiver, a second infrared receiver, a color camera module, a first moving member, a second moving member, a first driving member, and a second driving member. The first moving member and the second moving member are slidably mounted on the base. The first driving member and the second riving member respectively drive the first moving member and the second moving member to slide along the base. The infrared emitting module is mounted on the first moving member. The color camera module is located between the first infrared receiver and the infrared emitter. The second infrared receiver is mounted on the second moving member. The first moving member and the second moving member respectively move the infrared emitting module and the second infrared receiver along the base relative to the first infrared receiver.

    Abstract: A lens module with physically stronger foundations and enhanced stability includes a circuit board, an image sensor thereon, a mounting bracket, an optical filter, and a lens unit. The mounting bracket is connected to the surface of the circuit board which has the image sensor. The optical filter is connected to mounting bracket and positioned above the image sensor. The lens unit is connected to the mounting bracket facing away from the circuit board through a frame of adhesive. The surface of the lens unit connected to the mounting bracket has protrusions which are positioned at inner edges of the adhesive layer. The protrusions are taller than the depth of the adhesive layer.

    Abstract: A precision cleaning device for cleaning and clearing a glue-dispensing needle includes a base, a supporting unit disposed on the base, a moving unit movably connected to the supporting unit, a clearing needle connected to the moving unit and facing the supporting unit, and an adjusting unit connected to the moving unit. The adjusting unit adjusts a movement of the moving unit to drive the clearing needle to move towards the glue-dispensing needle on the supporting unit, allowing the clearing needle to pass through the glue-dispensing needle to completely clean and clear the glue-dispensing needle. The cleaning device also prolongs the service life of the glue-dispensing needle.

    Abstract: An easily disassembled lens module in a terminal device includes a lens assembly, a circuit board, and a structural member. The circuit board includes a first portion, a second portion, and a third portion which are connected in sequence. The first portion is connected to the lens assembly, the second portion and the third portion protrude from the lens assembly. The structural member includes a connecting portion fixed on the third portion and at least one pulling portion protruding from the third portion. After installation in the terminal device, the lens assembly can be disassembled by using the at least one pulling portion to pull on the structural member so that the lens assembly can be disassembled without using tools and without causing damage.

    CPC classification number: B21D5/01 B21D5/002 B21D5/006

    Abstract: A structure to apply flexing to an object to test resilience to being bent has a first portion and a second portion. The structure includes a base, a rotating member, a pressing plate, and an adjusting assembly. The base defines first and second receiving grooves, and the second receiving groove receives the first portion. The rotating member on the base is partially received in the first receiving groove. An abutting surface of the rotating member is recessed to form a third receiving groove which receives the second portion. The pressing plate on the base presses against the first portion. The adjusting assembly controls the rotating member to rotate towards the base about a desired angle, thereby causing the second portion to be bent with respect to the first portion.
