Description

Technical Field

[0001] This utility model relates to the field of circuit board processing and conveying technology, and in particular to a conveying mechanism for circuit board processing. Background Technology

[0002] FPC stands for Flexible Printed Circuit, also known as a flexible printed circuit board, or flexographic circuit board. It is mainly used in many products such as mobile phones, laptops, PDAs, digital cameras, and LCMs. FPC boards can be freely bent, folded, and rolled, enabling lightweighting, miniaturization, and thinning, thus achieving integration of components and wiring connections. However, because flexible boards are primarily used in applications requiring bending, improper design or manufacturing processes can easily lead to defects such as micro-cracks and solder joint defects.

[0003] During the process of conveying circuit boards, the lack of clamping and positioning of the circuit boards results in a lack of precision when laser drilling. Existing devices only transport circuit boards via conveyor belts, causing only one side of the circuit board to face the processing component, resulting in a small processing range. Therefore, we propose a conveying mechanism for circuit board processing. Utility Model Content

[0004] The purpose of this invention is to provide a conveying mechanism for circuit board processing, which solves the existing problems.

A movable shaft is rotatably installed on one side of the first mounting frame, and an adjusting frame is fixedly installed on the outer side of the movable shaft. Vacuum nozzles are fixedly installed at the four corners of one side of the adjusting frame.

[0007] As a further improvement to the above solution, a mounting base is fixedly installed on the top of the turntable, an electric telescopic rod is fixedly installed around the outer perimeter of the mounting base, a first motor is fixedly installed at the output end of the electric telescopic rod, a first drive shaft is fixedly installed at the output end of the first motor, and the first mounting bracket is fixedly installed on one side of the first drive shaft.

[0008] As a further improvement to the above solution, a second motor is fixedly installed on one side of the first mounting bracket, and the movable shaft is fixedly installed at the output end of the second motor.

[0009] As a further improvement to the above solution, a vacuum pump is fixedly installed on one side of the adjustment frame, and a negative pressure extraction pipe is fixedly installed at the output end of the vacuum pump, which is connected to the vacuum nozzle.

[0010] As a further improvement to the above solution, a storage battery is fixedly installed on one side of the adjustment frame, and the storage battery is electrically connected to the vacuum pump.

[0011] As a further improvement to the above solution, a second mounting bracket is fixedly installed on both the right and rear sides of the fixed frame, and a conveyor belt is rotatably installed on the inner side of the second mounting bracket.

Transmission gears are fixedly installed on the outer sides of both the second drive shaft and the rotating shaft, and adjacent transmission gears mesh with each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) A conveying mechanism for processing circuit boards of this utility model places the circuit board to be processed on the right side of the conveyor belt and controls the second motor to drive the adjustment frame to rotate and adjust the angle so that the vacuum nozzle on the adjustment frame is above the circuit board. The vacuum pump is controlled to start to extract negative pressure from the negative pressure extraction pipe.
