The invention relates to an intelligent production line for high-speed aluminum bar saw cutting. The intelligent production line comprises a machine body and an operation table used for controlling the machine body to run; the machine body comprises a feeding device used for conveying aluminum bars, a feeding sizing device used in cooperation with the feeding device, a main machine saw cutting device used in cooperation with the feeding sizing device and a discharging device used for discharging after saw cutting is completed. According to the intelligent production line for high-speed aluminum bar saw cutting, monomer project research and development and system organic sets of series functions including batch automatic feeding, numerical control sizing, saw cutting clamping, finished product numerical control stacking, weighing, coding and the like of workpieces are studied, overall process numerical control problems (controllable beat) of a series of motions such as feeding, positioning, clamping, hoisting, weighing and coding are solved, and the production line is worthy of popularization.

The invention discloses an indoor positioning system combined with a Bluetooth Beacon and a smartphone and a positioning method thereof. The system comprises a Bluetooth Beacon, a smartphone and a server, wherein the smartphone is integrated with an accelerometer module and a magnetometer module, has a network function, and can be connected with the server through 3G, 4G or WiFi to upload locationdata after obtaining user permissions; the server acquires the uploaded location data of a user, and then processes the data according to the requirements of a system designer. The method comprises the following steps: deploying the Bluetooth Beacon, and setting an initial location; enabling the user to open Bluetooth and execute client applications, and real-timely positioning and monitoring a Bluetooth Beacon signal; when the user monitors a predeployed Beacon signal, determining whether the distance is within a threshold, and if yes, executing a filtering algorithm; setting a Bluetooth module of the smartphone as a full duplex mode; and uploading a positioning result to the server after obtaining the user permissions. According to the method disclosed by the invention, the positioningaccuracy with an error within 5 meters can be ensured, and a low deployment cost can be achieved.

An elastic fastener has developed to be assembled and disassembled easily, even without the use of a separate tool, that can be firmly and repeatedly coupled, and an actuator module using the same. The elastic fastener includes a hollow socket adapted to be elastically inserted into insertion holes formed on joint members, and a fixing pin coupled to a hollow portion of the hollow socket. The actuator module includes a housing including a first lateral plate having at least one insertion hole for inserting an elastic fastener, a second lateral plate positioned to face the first lateral plate and provided with at least one insertion hole of an identical shape as the insertion hole of the first lateral plate, and two lateral surfaces positioned between both ends of the first and second lateral plates while facing each other; a first connection member coupled to a driving shaft of an actuator contained in the housing via the first lateral plate, the first connection member having at least one insertion hole of an identical shape as the insertion holes of the first and second lateral plates, the first connection member having a flat plate shape; and an elastic fastener including a hollow socket adapted to be elastically inserted into the insertion hole formed in the first connection member and a fixing pin coupled to the hollow portion of the hollow socket.
