Description

Technical Field

[0001] The invention relates to the field of circuit board processing, and in particular to a circuit board pressing device. Background Art

[0002] In the manufacturing process of circuit boards, a key step is to pressurize and fix a layer of the circuit board structure on the base structure. Patent application number: CN202210767846.2 discloses an automated pressing device for processing circuit boards, including an operating platform, a lower mold, an L-shaped connecting plate, a hydraulic cylinder, a control panel, two screws and an upper mold. A card slot is provided on the inner side walls on both sides of the operating platform, and a fixed plate is slidably connected to the inner surface of the operating platform card slot. An L-shaped connecting plate is welded on the upper surface of the fixed plate. A card slot is provided on the inner side walls on both sides of the lower mold. The staff pushes the fixed plate to move upward, so that the L-shaped connecting plate pushes the movable baffle to move, and at the same time, the movable baffle pushes the circuit board after pressing inside the lower mold to move out of the lower mold, thereby facilitating the staff to remove the circuit board from the lower mold to a certain extent. However, this type of pressing device needs to wait for the pressing of the previous circuit board to be completed before the pressing operation of the next circuit board can be performed, resulting in low production efficiency of circuit boards.

[0003] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a circuit board pressing device.

The circuit board to be pressed is transported forward through the first conveyor belt. After the circuit board is transported to the specified position, the material picking cylinder is started, the piston rod on the material picking cylinder is extended, and the material picking plate descends. After the suction cup contacts the circuit board, the vacuum pump is used to suck the vacuum at the suction cup position, and a negative pressure is formed at the suction cup position. The circuit board is adsorbed on the suction cup, and the material picking cylinder is started. The piston rod on the material picking cylinder is shortened, and the circuit board rises with the material picking plate. The material picking motor drives the material picking plate to rotate, and the circuit board rotates with the turntable. After the circuit board reaches the top of one of the bottom plates, the material picking cylinder is started again, the material picking plate descends, and the circuit board is placed on the bottom plate After being positioned in the groove, the vacuum pump stops sucking air, the circuit board is separated from the suction cup, and after the circuit board is separated from the suction cup, the material picking plate rises, the two-way cylinder is started, and the two piston rods on the two-way cylinder move, and the two lifting rings approach each other.

The fixed rod is inserted into the lifting ring again, and the limit cylinder starts. The piston rod on the limit cylinder extends, and the bottom plate is pulled out of the fixed groove. Due to the action of the torsion spring, when the bottom plate slides out of the fixed groove, the torsion spring drives the pressure plate to rotate around the support rod, and the pressure plate and The circuit boards are separated, the picking cylinder is started, the picking plate descends, and after the suction cup absorbs the pressed circuit boards, the picking cylinder is started, the picking plate rises, the picking motor is driven, and the picking motor drives the picking plate to rotate, and the circuit boards rotate with the picking plate. After the circuit boards rotate to above the second conveyor belt, the suction cup stops sucking air, and the pressed circuit boards are placed on the second conveyor belt and collected as the second conveyor belt runs, and the operation is cyclic. This device realizes the pressing operation of the circuit boards, and inserts the circuit boards into the fixed grooves one by one for pressing and pressure-maintaining operations. There is no need to wait for the previous circuit board to be pressed before continuing the next pressing, which greatly improves the production efficiency of the circuit boards.
