Description

TECHNICAL FIELD

[0001] The utility model relates to SMT pick and place machine technical field, specifically related to a kind of SMT pick and place machine clamping device. BACKGROUND

[0002] SMT pick and place machine is the special equipment of surface assembly technology (Surface Mounted Technology, for short SMT), also called "mounting machine" or "surface mounting system". It is a kind of high-tech automatic equipment, mainly used to accurately place electronic components (such as chip, capacitor, inductor etc.) on printed circuit board (PCB). SMT pick and place machine greatly improves the production efficiency and product quality of electronic products through its high-precision, high-speed mounting capacity, and is the indispensable key equipment in modern electronic manufacturing industry. In the use process of SMT pick and place machine, clamping device as one of key components plays a crucial role in ensuring the stability and precision of printed circuit board (PCB) in the process of patching.

[0003] Some existing SMT pick and place machine clamping devices excessively rely on manual operation when in use, which limits its degree of automation to some extent and is not conducive to improving production efficiency.

[0004] For example, the SMT pick and place machine clamping device disclosed in the patent with announcement number CN217721653U aligns the circuit board with the fixing groove in the fixed plate, then presses the circuit board, the two ends of the circuit board respectively extrude the inclined surface, so as to drive the clamping block to move to both sides, then the circuit board can continue to move downward until the two ends of the circuit board align with the clamping groove, at this time the spring in the movable groove pushes the movable column to reset, the movable column drives the clamping block to reset and move, so as to drive the clamping groove to clamp the circuit board, thereby completing the fixation of the circuit board. When the circuit board needs to be disassembled, first pull the push piece, the push piece moves in the groove, at the same time drives the connecting rod to move along the connecting hole, the connecting rod drives the clamping block to move away from the circuit board, so that the clamping groove no longer clamps the circuit board, then the circuit board can be taken out.

[0005] Although the above-mentioned SMT pick and place machine clamping device only needs to align the circuit board with the inclined surface in the fixing groove, and press the circuit board into the fixing groove to complete clamping and fixation. But the SMT pick and place machine clamping device excessively relies on manual operation in the operation process, from the alignment of the circuit board, pressing fixation to disassembly and release, all need manual intervention, which limits its degree of automation and production efficiency to some extent. In order to improve production efficiency, reduce labor cost and improve product quality stability, it is necessary to improve and optimize the device to reduce or eliminate the dependence on manual operation and introduce more advanced automatic control technology.
