Description

Technical Field

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

[0002] Circuit board can be called printed circuit board or printed circuit board, also known as flexible circuit board. Flexible circuit board is made of polyimide or polyester film as the base material. It is a highly reliable and excellently flexible printed circuit board with the characteristics of high wiring density, light weight, thin thickness and good bendability.

[0003] When processing circuit boards, a circuit board loading device is required to load the materials. Patent application number: CN202122872828.4 discloses a loading mechanism and processing machine for printed circuit boards, including: a conveying device, a silo, a support seat, a board separation device and a material taking device. The conveying device transports a tray carrying a printed circuit board; the silo has a storage space, and the first storage bin and the second storage bin both include a first positioning rod, a second positioning rod, a third positioning rod and a fourth positioning rod. The first positioning rod, the second positioning rod, the third positioning rod and the fourth positioning rod are arranged on the support seat in pairs; the first positioning rod, the second positioning rod, the third positioning rod and the fourth positioning rod surround the storage space. However, this type of loading device cannot adjust the size of the storage space, resulting in the inability to meet the processing needs of circuit boards of different sizes.

Nuts threadedly connected to the threaded columns are provided on the threaded columns. The positions of the two positioning plates are adjusted according to the width of the circuit board to be processed. After the positioning plates are adjusted to the appropriate position, the bolt is turned. When the bolt is turned, the bolt moves close to the positioning rod. After the bolt and the positioning rod are squeezed, the positioning rod is fixed, thereby fixing the two positioning plates, and adjusting the distance between the two limit plates according to the length of the circuit board. After the limit plate is adjusted to the appropriate position, the nut is turned. The nut is threadedly connected with the threaded column. When the nut is rotated, the nut squeezes the limit block to fix the limit block on the support plate, thereby adjusting the distance between the two limit plates. After the limit plate and the positioning plate are adjusted to the right position, the circuit board to be processed is neatly stacked on the push plate, and the circuit board is positioned by the positioning plate and the limit plate.

The device meets the feeding needs of circuit boards of different sizes by adjusting the positions of the positioning plate and the limit plate.

[0008] Preferably, the positioning plate is also fixed with a plurality of nozzles connected to an air pump. When the manipulator grabs a circuit board, the gas compressed by the air pump is ejected through the nozzle, and the airflow enters between two adjacent circuit boards to separate the circuit boards, thereby avoiding the adsorption force between the circuit boards causing multiple circuit boards to be grabbed.
