Abstract: A spot gluing device includes a base for controlling the spot gluing device; a work plate movably mounted to the base in a first longitudinal direction; a support mounted to the base above the work plate; a first driving device movably mounted to the support frame; a second driving device mounted to the support and connected to the first driving device, the second driving device driving the first driving device to move relative to the work plate in a second longitudinal direction perpendicular to the first longitudinal direction; and a gluing assembly mounted to the first driving device facing the work plate. The first driving device drives the gluing assembly to move in a third longitudinal direction perpendicular to the first longitudinal direction and the second longitudinal direction.

Abstract: A host computer includes an enclosure, a motherboard mounted in the enclosure. The motherboard includes a battery, a reference voltage generating circuit, an electronic switch, an alarm unit mounted on the enclosure, and a comparator. The reference voltage generating circuit generates a reference voltage. The comparator is connected to the battery and the reference voltage generating circuit to receive the reference voltage and detect a voltage of the battery. The comparator compares the detected voltage of the battery with the reference voltage, and outputs a control signal to turn on the electronic switch to start the alarm unit when the voltage of the battery is less than the reference voltage.

Abstract: A carrier includes a main bracket. The main bracket includes a first mounting member and a second mounting member. The first mounting member includes a first sidewall and a first front wall. The second mounting member includes a second sidewall and a second front wall. The first front wall is telescopically extensible relative to the second front wall to adjust a retaining width between the first sidewall and the second sidewall in order to couple to various size data storage devices.

Abstract: A parallel robot includes a fixed platform, a movable platform, a plurality of control arms, a rotation arm, a plurality of first actuators, and a second actuator. The control arms are rotatably connected to the fixed platform and the movable platform, respectively. Opposite ends of the rotation arm are universally rotatably connected to the fixed platform and the movable platform, respectively. The first actuators are to respectively move the control arms. The second actuator is to drive the rotation arm to rotate around the center axis of the rotation arm. Each control arm includes a first transmission unit including a transmission member. Each first actuator includes a transmission gear to engage the transmission member of the control arm.

Abstract: An electronic device assembly includes a protective apparatus, a first electronic member, and a pivotal mechanism. The protective apparatus includes an upper housing and a lower housing. The first electronic member is housing in the upper housing. The pivotal mechanism received in the lower housing rotates the upper housing relative to the lower housing. When the upper housing is unlatched by the pivotal mechanism from the lower housing, the first electronic member leaves the protective apparatus, and when the upper housing is driven by the pivotal mechanism to latch to the lower housing, the first electronic member is shielded in the protective apparatus.

Abstract: An exemplary electronic device (30) includes a main body (40) and two supporting mechanisms (60). The supporting mechanisms are formed at two adjacent corners of the main body respectively. Each supporting mechanism includes a support leg (62) and a sliding member (63). The support leg is rotatably connected to the main body. The sliding member is slidably connected to the main body. The support leg is movably connected to the sliding member, in order to make the support leg disengage form the sliding member when the sliding member sliding relative to the main body.
