The invention discloses an automatic sand tank device for barbell plates, which relates to the technical field of barbell plate production, a workbench, a clamping mechanism, a shaking mechanism and a sand tank mechanism. The clamping mechanism is arranged in the middle of the workbench and includes a hinged joint bar, positioning plate, connecting bar, hydraulic cylinder 1 and lifting rod, the clamping mechanism is used for automatic clamping of the barbell plate shell, the shaking mechanism is arranged on the side of the clamping mechanism and includes a rectangular frame, a mounting shaft, a transmission shaft, Hydraulic cylinder 2, lifting plate and lifting bar, the shaking mechanism is used to automatically shake the shell of the barbell plate, and the sand tank mechanism is set above the clamping mechanism and includes a support pipe, a sand storage bucket, a driving motor, a conveying shaft and a conveying pipe. The tank sand mechanism is used for automatic tank sand to the barbell plate shell. To sum up, the automatic sand tank device of the barbell plate of the present invention has the characteristics of ingenious design, reasonable structure, convenient use, labor saving and high sand tank efficiency.

The invention provides a DMA-based SPI communication method, comprising steps: after the processor is powered on, the SPI interface is initialized; the processor initializes the receiving and sending configuration of the DMA; When the data to be sent is reached, the DMA is started to send the data to be sent in parallel. When the data to be sent is sent, the DMA generates a transmission completion interrupt; the main program of the processor loops to detect the SPI interface. When the main program of the processor detects the data to be received, Start the DMA to receive the data to be received in parallel, and when the data to be received has been received, the DMA generates a receive completion interrupt. The invention relates to electronic equipment and a readable storage medium for executing the above method; the invention also relates to a DMA-based SPI communication device. The invention adopts the DMA technology and the interrupt generated by the DMA, so that the main program of the processor can quickly take and process the data in the interrupt service program, and obviously reduce the time resources occupied by the single-chip microcomputer.

The invention provides an ultrasonic vibration rotary drawing-out device, and relates to a drawing-out device for machined parts. The middle of a transmission shaft (21) is fixedly sleeved with a collecting ring (22); the collecting ring (22) is slidably connected with a carbon brush (2); the carbon brush is externally connected with an ultrasonic generator (5); a power wheel (27) is externally connected with a power mechanism (3); a flange at the lower end of the transmission shaft (21) is connected to the upper end of an internal rotary sleeve (17); the upper end of an amplitude-change pole (9) is fixed at the lower end of the internal rotary sleeve; the lower end of the amplitude-change pole (9) is provided with a tubular drawing-out drill (10); a cooling water jetting mechanism is arranged on the lower part of the drawing-out drill; a transducer (16) is arranged in the internal rotary sleeve (17); and a ceramic plate (8) arranged in the middle of the transducer is connected with the collecting ring (22) through an electrode (7) and a wire (4). On the basis of an ultrasonic vibration principle, the accuracy of drawn-out silicon sticks or sapphire bars is high, and the machining cost of the ultrasonic vibration rotary drawing-out device is lower than that of a drawing-out device in the prior art.

The invention belongs to the technical field of edge trimming of lithium batteries, in particular to an edge trimming device for lithium battery production and a method thereof. The operation of the existing edge trimmer is complicated, and the lithium battery needs to be held by hand during operation, and the distance between the hand and the edge of the cutter is too close , there are potential safety hazards, and it is not convenient to fix the lithium battery. The following scheme is proposed, which includes the console. There are two knives, a vacuum cleaner is installed under the operating table, a cutting table is installed on the top of the operating table, and a lithium battery is placed on the cutting table. On both sides, the top of the cutting table is provided with a vertical plate, and a pressure plate is slidingly installed on one side of the vertical plate. The invention is easy to operate, convenient to fix the lithium battery, avoids stabilizing the lithium battery by hand, and can stay away from the cutter to avoid potential safety hazards.

The invention relates to a quick assembly type tent. The quick assembly type tent is provided with a canopy cloth, an inner tent body and a support used for supporting the inner tent body, wherein the inner tent body is covered with the canopy cloth, the support comprises an automatic support body and telescopic support bodies, the automatic support body is in the shape of an umbrella and is composed of frames, a connecting block and a connecting rod, the upper end of the connecting rod is riveted to the lower side of the connecting block, the lower end of the connecting rod is connected to the center of the inner tent body through braid, the four frames rotating in the vertical direction extend from the periphery of the connecting block, the inner tent body is connected with the frames in a sleeving mode through frame sleeve rings sewn onto the inner tent body, the telescopic support bodies are detachably installed at the outer ends of the frames through V-shaped installation bases fixed at the upper ends of the telescopic support bodies, and rod bodies of the telescopic support bodies penetrate through telescopic support body sleeve rings sewn onto the inner tent body. According to the quick assembly type tent, quick disassembly and assembly of the tent are achieved through the automatic support body and the telescopic support bodies installed on the inner tent body, detachment of the automatic support body is not needed, and time spend on assembly and disassembly is shortened greatly and can be saved by more than half compared with ordinary tents.

The invention discloses a printer security enhancement system, method and electronic equipment. The system includes: a terminal installed with a target application program, a server and a printer, and the target application program communicates privately with the server; wherein, the terminal receives the After the print instruction for the target electronic resource, the identification information of the target electronic resource and the target application is sent to the server; the server associates and stores the identification information of the target electronic resource and the target application, and returns a print confirmation signal; the printer displays the identification information of the printer. Two-dimensional code, after the terminal scans the two-dimensional code through the target application program, it sends the scanned code information to the server, and establishes a communication connection between the printer and the server based on the code information; the server sends the target electronic resource to the printer through the communication connection. The system enhances printer security and reduces the risk of compromise of targeted electronic resources.
