Description

Technical Field

[0001] This utility model relates to the field of circuit board production equipment technology, and in particular to an automatic circuit board punching and conveying device. Background Technology

[0002] Circuit boards are also known as ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, PCBs, aluminum-based boards, high-frequency boards, thick copper boards, impedance boards, ultra-thin circuit boards, and printed circuit boards (using copper etching technology). Circuit boards miniaturize and visualize circuits, playing a crucial role in the mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards can also be called printed circuit boards or printed circuit boards.

[0003] Utility model CN210527833U discloses an automatic conveying device for circuit board punching, including a worktable. The worktable is symmetrically equipped with electric hydraulic cylinders, each with a fixed block. A first electric telescopic rod is fixedly mounted on the feeding table, and a feeding plate is fixedly mounted on the first electric telescopic rod. A heat-conducting plate is fixedly mounted on the preheating box, and a punch press is fixedly mounted on the preheating box. A fixed seat is fixedly mounted on the rotating seat. A lifting plate is threadedly connected to the threaded rod, and lifting columns are symmetrically fixed on the lifting plate. Two second electric telescopic rods are fixedly equipped with vacuum pumps, and multiple vacuum suction cups are fixedly mounted on the connecting plate. This utility model, based on a conventional conveying device, incorporates preheating and transmission devices, improving work efficiency and production quality. It has broad market prospects and is suitable for widespread application. However, while the device incorporates preheating when conveying circuit boards, it only heats one side of the circuit board through the heat-conducting plate, resulting in uneven heating. Furthermore, after heating on the heat-conducting plate, the circuit board needs to move a certain distance to reach the punch press, causing a temperature drop during this movement.

[0004] Therefore, it is necessary to provide a new automatic conveying device for circuit board punching to solve the above-mentioned technical problems. Utility Model Content

[0015] Compared with related technologies, the automatic circuit board punching and conveying device provided by this utility model has the following advantages:

[0016] Beneficial effects:

[0017] 1. The first electric cylinder drives the push plate to move, thereby pushing the circuit board onto the heating plate. The fourth electric cylinder drives the upper heating plate to move down, so that the upper heating plate is in contact with the surface of the circuit board, thereby heating both sides of the circuit board and making the circuit board heat more evenly.

[0018] 2. After preheating for a period of time, the connecting frame is pushed by the second electric cylinder, causing the connecting frame to slide on the two sliding rods, thereby moving the circuit board. The circuit board is heated while moving. After the circuit board is heated, it can be directly moved to the punch press, making it less likely for the circuit board to cool down during the process.
