Description

Technical Field

[0001] The utility model relates to the technical field of circuit board transfer equipment, and more specifically, to a transfer frame for circuit boards. Background Art

[0002] Circuit boards are a crucial component of electronic products. Rigid-flex boards, which combine flexible and rigid circuit boards through lamination and other processes, are widely used, combining the characteristics of both FPCs and PCBs. Currently, due to the complex production processes, low yield rates, high production difficulty, and long production cycles, rigid-flex boards are crucial for ensuring the soldering quality between components on the boards.

[0003] Based on the above, the inventors found that the existing circuit board transfer mostly uses a dedicated transfer frame, which is set with different size specifications. Each transfer frame can only store circuit board products of the same size and specification. The application range of the transfer frame is relatively narrow. At the same time, when the circuit board is transferred through the transfer frame, a large amount of dust is easily attached to its surface due to static electricity, and the chemical substances in the dust may corrode the metal parts on the circuit board, causing oxidation and rust, causing damage to the circuit board, and affecting the service life of the circuit board. Therefore, in view of this, the existing structure is studied and improved, and a transfer frame for circuit boards is provided, in order to achieve the purpose of greater practical value.

At the same time, the addition of an anti-static chain can ground the static electricity on the circuit board to achieve an anti-static effect, and with the cooperation of the air supply mechanism and the air nozzle, the dust on the surface of the circuit board can be cleaned, solving the problem that the chemical substances in the dust may corrode the metal parts on the circuit board, causing oxidation and rust, and causing damage to the circuit board.
