Description

Technical Field

[0001] This utility model relates to the field of spray coating and curing technology, specifically to a PCB board spray coating and curing device with high efficiency. Background Technology

[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is made using electronic printing technology, it is called a "printed" circuit board. During the manufacturing process, PCBs undergo a spray coating process, followed by heating to accelerate the curing of the conformal coating. Existing spray coating and curing equipment typically uses two clamps to hold and fix the PCB, and then uses a rotary motor to drive the PCB to flip and achieve double-sided spray coating. The stress experienced by the clamps during the flipping process can easily cause the fragile PCB to deform and break, resulting in low safety of the equipment. Utility Model Content

The electric rotating base 25 is used to control the rotation of the PCB board to perform spraying and curing operations in sequence. The support 241 is used to install the first motor 243. The first motor 243 is used to drive the screw 242 to rotate. The screw 242 is used to engage the connecting clamp 24 to move. The clamp 24 is used to clamp and fix the PCB board. The heating box 26 is used to heat and cure the sprayed PCB board. The electric lifting horizontal moving column 27 is used to adjust the height position of the spraying equipment 23. The slide rail 22 is used to adjust the position of the spraying equipment 23 in conjunction with the slider 21. The second motor 28 is used to drive the gear 291 to rotate. The gear 291 is used to engage the transmission rack 29 to limit the movement of the slider 21 within the slide rail 22. The threads on the two ends of the screw 242 are in opposite directions, and the top of the clamping block 24 has an L-shaped structure; The bidirectional threaded screw 242 can engage with the clamping block 24 to control the two clamping blocks 24 to move towards each other to complete the installation and positioning of the PCB board, and is suitable for installing PCB boards of different sizes. Both the slide rail 22 and the rack 29 have a semi-circular ring structure, and the side of the gear 291 meshes with the rack 29.

The PCB board can be installed, removed, sprayed and cured at the same time. Working principle: The base 11 serves as the main load-bearing structure, providing overall structural stability through contact with the contact surface; The PCB board to be processed is placed between two clamping blocks 24.

The electric lifting horizontal moving column 27 can adjust the height position of the spraying equipment 23. Motor 28 drives gear 291 to rotate. Under the meshing transmission between gear 291 and rack 29, slider 21 can move within the slide rail 22. Slider 21 drives the spraying equipment 23 to the bottom of the PCB board to achieve double-sided spraying. Then, the electric rotating seat 25 rotates to move the sprayed PCB board to the heating box 26 for heating and curing. At the same time, the previously installed PCB board to be processed will be moved to the spraying equipment 23 for spraying. This step involves simultaneous spraying and curing operations, saving time and making the equipment more efficient.
