Technical Field

[0001] The utility model relates to the technical field of PCB circuit board processing, in particular to a PCB circuit board spraying device. Background Art

[0002] PCB circuit board generally refers to printed circuit board, also known as printed circuit board. It is an important electronic component, the support body of electronic components, and the carrier of electrical connection of electronic components. To protect the circuit board from environmental corrosion, the parts on the PCB circuit board need to be sprayed with three-conformal paint. The three-conformal paint has excellent high and low temperature resistance. After curing, it will form a transparent protective film. The three-conformal paint is applied to the surface of the PCB circuit board to protect the PCB circuit board parts from mildew, moisture and salt spray.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model controls the motor, mounting structure plate, micro-cylinder structure, clamping plate, rubber protective pad, limiting rail, conveying platform component, driven gear structure, and driving motor component through the PLC control motor as the power source. The PLC control motor not only drives the PCB board to flip over through the rotation of its shaft, but also enables the PCB board to be quickly and accurately flipped over, thereby performing double-sided spraying, greatly improving the spraying efficiency. The mounting structure plate provides a stable installation foundation for the micro-cylinder structure, ensuring the stability of the micro-cylinder structure during operation. At the same time, the limiting rail on the mounting structure plate limits the movement trajectory of the clamping plate, further improving the accuracy and stability of the clamping action. The micro-cylinder structure drives the clamping plate close to or away from the PCB board through the extension and contraction of its shaft, thereby achieving clamping and releasing of the PCB board. This fast and precise clamping mechanism enables the PCB board to be quickly fixed and prepared for spraying, reducing manual intervention and waiting time. The clamping plate directly contacts and clamps the PCB, while the rubber protective pad provides increased cushioning and anti-slip properties during the clamping process, effectively protecting the PCB surface from damage. This improves clamping stability and ensures the safety of the PCB during the spraying process. The limiting track restricts the movement of the clamping plate, ensuring that the clamping action always follows the predetermined path. This improves the accuracy and stability of the clamping action, avoiding problems such as PCB damage or uneven spraying caused by offset of the clamping plate. The conveying platform component, driven gear structure, and drive motor component together constitute the PCB conveying system. The drive motor component drives the outer roller of the driven gear structure to rotate via a transmission belt, which in turn drives the transmission chain in the conveying platform component. This allows the PCB to be automatically and quickly transported to the spraying position for spraying, greatly improving spraying efficiency.

[0014] When the PCB is delivered to the spraying position, a micro-cylinder structure quickly pushes the clamping plate toward the PCB to clamp it. The PLC then activates the motor, driving the PCB to flip over for double-sided spraying. During the spraying process, the spray device precisely applies the coating according to preset parameters. Once the spraying is complete, the micro-cylinder structure releases the clamping plate, and the PCB continues to be transported to the next workstation or collection area.

[0028] Working Principle: During use, the PCB clamping member 8 is securely mounted on the transmission chain of the conveying platform member 2 via its connecting insert 87. The PCB clamping member 8 is secured using a limit insert 89 and a limit mounting bolt 891 to ensure stability during conveying. The micro-cylinder member 83 is in a standby state, ready to receive a signal to perform the clamping action. When the PCB is conveyed to the clamping position, the micro-cylinder member 83 receives a control signal and its shaft extends. This extension of the shaft pushes the clamping plate 84 along the limit rail 86 until the rubber protective pad 85 on the clamping plate 84 fits tightly against the PCB surface. The rubber protective pad 85 provides the necessary cushioning and anti-slip protection, ensuring the PCB is securely clamped. The drive motor member 10 is activated, and its shaft rotates the outer roller of the driven gear member 9 via a drive belt. This rotation drives the transmission chain in the conveying platform member 2, achieving horizontal conveyance of the PCB on the conveying platform. The PCB is then conveyed to a designated position below the spraying device 5, ready for spraying. The paint in the spray paint tank 6 is stably transported to the spraying device 5 via a telescopic tube member 7. The design of the telescopic tube member 7 ensures that the spraying device 5 maintains a continuous and stable connection with the paint source during the lifting process. The lifting device 4 adjusts the position of the H-shaped mounting bracket 51 according to the preset spraying height, providing a stable support platform for the sprayer 52. The sprayer 52 starts and controls the spray head 53 to spray paint. The position and angle of the spray head 53 are adjusted as needed to achieve precise spraying of different areas and angles of the PCB board. During the spraying process, the L-shaped fixing structure 54 ensures the stability of the sprayer 52, preventing it from shaking and thus ensuring spraying quality. Simultaneously, the PLC-controlled motor 81 inside the PCB board clamping member 8 is activated. The shaft rotates, driving the mounting structure plate 82 to rotate, allowing the PCB board to be flipped over for double-sided spraying. After the PCB board is double-sided sprayed, it continues to move forward along the conveyor platform to the next workstation or collection area. The micro cylinder structure 83 receives the release signal, the shaft retracts, and the clamping plate 84 releases the PCB board to complete the release of the PCB board. At the same time, a new PCB board is fed into the PCB board clamping member 8 for clamping, ready for the next round of spraying operation.
