Abstract: A roller assembly includes a workbench, a roller module located above the workbench, and a locking assembly coupled to the roller module and configured to position the roller module above the workbench. The roller module includes a driving device and a pressure roller. The driving device is coupled to the pressure roller through a crank assembly. The crank assembly drives the pressure roller to move along a track to roll on a work-piece positioned on the workbench.

Abstract: A pivoting clamping assembly includes a carrier, clamping arm pivotably coupled to the carrier and configured to clamp or release a workpiece on the carrier, a lock arranged on the carrier and configured to lock the clamping arm when the clamping arm is rotated toward the workpiece, and at least one clamping block coupled to the clamping arm by a shaft and at least one resilient member. The shaft pivotably couples a pivoting joint of the at least one clamping block to the clamping arm. The at least one resilient member is coupled between the clamping block and the clamping arm.

Abstract: A device with a processing unit and a storage device also has a base, a cover including a plurality of guiding holes, a plurality of receiving members, an installation member, a plurality of first sensing devices, and a plurality of second sensing devices. The processing unit determines by a specific one of the first sensing devices corresponding to a specific one of the receiving members that the installation member is to acquire a fastening element from the specific receiving member. Then, the processing unit determines by a specific one of the second sensing devices corresponding to a specific one of the guiding holes that the installation member is to move towards the specific guiding hole. The processing unit controls the installation member to fasten the fastening element to an electronic device through the specific guiding hole when the specific first sensing device corresponds to the specific second sensing device.

Abstract: A device for installing an elastic sealing ring on an electronic device includes a clamp module and a pressing module. The clamp module includes a sliding column defining two grooves, two linkage plates, and two pins secured on the bottom end of the linkage plates. The pressing module includes a bracket and a knockout plate. The linkage plates are rotatably installed on the bracket and the sliding column can slide relative to the bracket. The knockout plate can slide relative to the bracket, to install the sealing ring on an electronic device.

Abstract: An automatic installation device for automatic procuring and fixing an object to a product is mounted on a base. The automatic installation device comprises an elevating mechanism, a loading mechanism for procuring the object, and a flexing mechanism connected between the elevating mechanism and the loading mechanism. The flexing mechanism is capable of driving the loading mechanism moving between the object and the product for aligning the object with the product in a first orientation. The elevating mechanism is capable of driving the loading mechanism to move in a second orientation perpendicular to the first orientation to drive the loading mechanism moving adjacent to the product and fixing the object to the product.

Abstract: An ejecting device includes a housing and a pushing mechanism received in the housing. The pushing mechanism includes a pushing component. The pushing component is movably secured to the housing for pushing an object. When the pushing mechanism is in a resisting state, the pushing component protrudes out of the housing to push the object. When the pushing mechanism is in an unresisting state, the pushing component retracts into the housing and disengages from the object.
