Description

Technical Field

[0001] The utility model relates to the field of circuit boards, in particular to a feeding device for processing circuit boards. Background Art

[0002] PCBs use printed circuit board technology to create conductive paths on insulating substrates, allowing electrical connections between electronic components. They are widely used in various electronic devices, including communications equipment, computers, consumer electronics, medical equipment, industrial control equipment, and aerospace equipment.

[0003] The circuit board manufacturing process is relatively complicated, and each process requires multiple processing and production processes. Usually, the circuit boards need to be placed together after processing. In order to reduce space occupation, the unformed circuit boards are often stacked in multiple layers. Before the circuit boards proceed to the next processing step, the stacked circuit boards need to be loaded. During loading, the air between the stacked layers of the circuit boards will be squeezed out during lamination. Under atmospheric pressure, two or more circuit boards will stick together. When the stacked circuit boards are loaded by a robot, the multiple stuck circuit boards need to be separated, which will affect the normal loading work.

[0004] Therefore, the utility model provides a feeding device for circuit board processing, which can separate the adhered circuit boards during feeding, thereby avoiding the simultaneous feeding of multiple circuit boards. Utility Model Content

[0016] The utility model also provides a feeding device for circuit board processing, including the above

[0017] The working principle of this utility model is:

[0018] The beneficial effects of this utility model are as follows: when the second lifting device drives the hopper to slide up and down, the hopper drives the first transmission belt to rotate. Because the hopper and the support are connected to opposite surfaces of the first transmission belt, the hopper and the support move in opposite directions. When the hopper descends, the first transmission belt drives the panel separator upward; when the hopper ascends, the first transmission belt drives the panel separator downward, ensuring that the panel separator always faces the circuit board adhered to it.

[0019] The hopper is controlled to rise to a set height, and the separator descends to a set height, ensuring that the separator always faces the stuck circuit board. The top plate and manipulator are controlled to descend until the circuit board triggers the proximity switch, at which point the manipulator grasps the board with its vacuum cups and removes the material. As the top plate and manipulator ascend, the two separators release high-pressure airflow at each end of the circuit board, dislodging the stuck one. Simultaneously, the high-pressure airflow quickly enters the space between the two boards, accelerating their separation and preventing multiple boards from clumping.
