Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, specifically to a printing mechanism for PCB board manufacturing. Background Technology

[0002] A PCB, also known as a printed circuit board, provides the electrical connections for electronic components. Its design primarily involves layout design; the main advantages of using PCBs are significantly reduced wiring and assembly errors, improved automation levels, and increased production efficiency. Based on the number of layers, PCBs can be classified as single-sided, double-sided, four-layer, six-layer, and other multi-layer circuit boards.

[0003] Chinese Patent No. CN217849797U discloses a solder paste printing device for PCB board manufacturing. The following solution is proposed: a printing mechanism and a limiting mechanism. The printing mechanism includes a printing box and a first electric telescopic rod bolted to the top outer wall of the printing box. A printer is bolted to the bottom outer wall of the first electric telescopic rod. The limiting mechanism includes a fixing plate and symmetrically distributed grooves on the bottom outer wall of the fixing plate. This invention, through its conveying component, can transport the PCB board during use. The second electric telescopic rod pushes a baffle to position the PCB board during use. A servo motor drives a transmission component to move the slider in relative or opposite directions during use, thereby limiting the position according to the width of the PCB board and preventing positional deviation during transport, which would affect printing quality.

[0004] However, the above technical solution has the following shortcomings: the limiting mechanism can only make simple adjustments to the position of the PCB board on the conveying component, and cannot effectively limit the PCB board. The limiting mechanism also cannot move with the PCB board, which causes positional deviation during circuit board transportation and affects the printing quality of the PCB board.

Compared with Embodiment 1, this embodiment also specifically discloses the structure of the conveying mechanism. The conveying mechanism includes a conveying motor 41, a driving roller 42, a driven roller 43, and a conveyor belt 44. The conveying motor 41 is fixedly connected to the mounting frame. The conveying motor 41 is a servo motor and is connected to the control system and power supply through wires. The driving roller 42 is rotatably disposed in the mounting frame 1. One end of the driving roller 42 is connected to the output end of the conveying motor 41. Multiple driven rollers 43 are provided and rotatably disposed in the mounting frame 1.

[0017] Example 3 like Figure 2-5 As shown, this utility model discloses a printing mechanism for PCB board production. Compared with Embodiment 2, this embodiment further discloses the structure of the adjustment component. The adjustment component includes a mounting cylinder 331, an adjusting screw 332, an adjusting sleeve 334, and a reset component. The mounting cylinder 331 passes through the fixing block 31 and is slidably connected to the fixing block 31. The adjusting sleeve 334 is rotatably connected to the mounting cylinder 331. The adjusting screw 332 is threadedly connected to the adjusting sleeve 334. One end of the adjusting screw 332 is fixedly connected to the limiting plate 32, and the other end of the adjusting screw 332 extends into the mounting cylinder 331. One end of the reset component is connected to... The fixed block 31 is connected, and the other end of the reset component is connected to the adjusting sleeve 334.
