Description

Technical Field

[0001] The invention relates to the technical field of pneumatic nailing, and in particular to a multi-station synchronous pneumatic nailing device for preparing a soft bed frame. Background Art

[0002] The preparation of a soft bed mainly involves nailing wooden strips through an air nail gun to form a bed frame, and then covering it with fabric, sponge, leather, etc. to form bed frame accessory modules, such as a headboard, and finally assembling them to form a complete bed. Currently, when companies prepare soft bed frames, they use robotic arms and molds for automated production. The wooden strips are first placed into the mold one by one, and then nailed through by an air nail gun mounted on the robotic arm to form a bed frame.

[0003] When preparing soft bed frames, this technology makes the air nailing operation highly automatic through a robotic arm, but it still nails one by one. Since the nailing position of each bed board is the same, in order to further improve production efficiency, we further propose a multi-station synchronous air nailing device for preparing soft bed frames, which can synchronously nail multiple nailing positions on multiple bed boards at the same time, further improving the preparation efficiency of the bed frame.

[0026] In order to realize accurate air supply from the air supply machine to the cylinder, the air supply machine is connected to a plurality of adapters through an air outlet pipe, a valve is provided on the adapter, and the adapter is connected to the cylinder through a connecting pipe.

[0027] In order to achieve hammering after nailing, the mounting frame can be movably arranged on the mechanical arm, and the moving distance of the mounting frame is equal to the distance between the gun head and the hammering block.

[0035] 3. In the present invention, after nailing, the striking block is moved to above the nail by moving the mounting frame, and the initial magnet is in contact with the striking block. The rotating shaft drives multiple winding shafts to wind up the pull rope, driving the magnet and the striking block to rise. After rising to a certain height, the suction force of the magnet is less than the elastic force of the spring and the pulling force of the pull rope, and the striking block is separated from the magnet and strikes the nail under the action of the reset spring, further striking the nail, thereby ensuring the stability of the bed frame connection and reducing the obstruction caused by the protrusion of the nail during transportation and use.

[0036] 4. Therefore, compared with the sequential nailing method in which a mechanical arm and a single nail gun are used in the prior art, the present invention uses multiple nailing mechanisms and adjusts the positions of the multiple nailing mechanisms through an adjustable nailing frame to adapt to the nailing processing of different bed frames.

At the same time, the movement of the mounting frame is used to move the striking block to the nail position, and the pull rope is wound up through the winding shaft to drive the magnet and the striking block to rise. After rising to a certain height, the striking block is struck on the nail under the action of the reset spring to ensure the integrity of the nailing and improve the connection quality of the bed frame.
