Description

Technical Field

[0001] The present invention relates to the field of circuit board processing equipment, and particularly to a circuit board processing and conveying mechanism. Background Art

[0002] During the processing of printed circuit boards (PCBs), multiple processes (such as drilling, soldering, and inspection) are required. Traditional conveying devices mostly adopt a conveyor belt structure with a fixed width, which has the following problems:

[0003] 1. Poor adaptability: It is impossible to flexibly adjust the conveying width, making it difficult to adapt to PCBs of different sizes.

[0004] 2. Low positioning accuracy: The PCB is prone to deviation during conveying, resulting in processing errors.

[0005] 3. Insufficient anti-damage ability: The surface components of the PCB are easily damaged due to friction or collision.

[0006] In the prior art, some devices improve positioning by adding guide bars or clamping mechanisms, but the structures are complex and the adjustment is inconvenient. Therefore, there is an urgent need for a conveying device with a simple structure, adjustable, and capable of precise positioning. Summary of the Invention

[0007] In view of the above problems, the present invention provides a circuit board processing and conveying mechanism, a conveying device with adjustable width, anti-offset function, and capable of protecting the surface of the circuit board, so as to improve the processing efficiency and product yield.

[0008] The technical solution of the present invention is as follows:

[0009] A circuit board processing and conveying mechanism includes a base, an adjustable conveying mechanism, a driving mechanism, and a positioning and anti-offset mechanism; the adjustable conveying mechanism is connected to the guide rail on the base through a sliding block, and a locking bolt is provided on the sliding block; the positioning and anti-offset mechanism includes guide bars and limit sensors arranged on both sides of the base, and an elastic buffer layer is provided on the guide bars; a flipping mechanism is provided at the end of the base, and the flipping mechanism includes a robotic arm and a vacuum chuck for grasping the circuit board and flipping it 180°.

[0010] In a further technical solution, a touch control panel is integrated on the side of the base, and the control panel is signal-connected to a PLC controller.

[0011] In a further technical solution, the guide rail has a T-shaped or dovetail-shaped cross-section, and the sliding block is embedded with a ball bearing to reduce the moving resistance.

[0012] In a further technical solution, the limit sensor is a photoelectric sensor or an infrared sensor, symmetrically installed on both sides of the front end of the base, and is used to detect the arrival signal of the circuit board and feedback it to the driving unit.

[0013] In a further technical solution, the elastic buffer layer is made of silica gel or polyurethane, and a V-shaped guiding groove is provided on the inner side of the elastic buffer layer.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. Through the adjustable conveying mechanism, it can meet the conveying requirements of circuit boards of various specifications;

[0016] 2. The combination of the elastic guiding strip and the anti-slip design can prevent the circuit board from shifting and surface damage;

[0017] 3. The integrated detection and flipping functions improve the degree of automation and reduce manual intervention. BRIEF DESCRIPTION OF THE DRAWINGS
