Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a curing device for circuit board coating. Background Art

[0002] Circuit board coating refers to coating a layer of protective material (generally three-proof glue) on the surface of a printed circuit board to improve its environmental resistance and reliability. The main purpose of coating is to protect the circuit board from factors such as moisture, dust, chemicals, and temperature changes, thereby extending the service life of the device. Currently, many enterprises carry out coating manually, that is, by manual spraying or brushing, coating on one side or both sides of the circuit board.

[0003] After manual coating is completed, the circuit board with the uncured coating needs to be transported into a curing device for curing. Most current curing devices use a conveyor belt for transportation, and the circuit board needs to be placed flat on the conveyor belt. In this process, if a double-sided coated circuit board is transported, it is easy to damage the coating layer, resulting in poor coating effect. Therefore, the current circuit board coating curing device is not suitable for double-sided coated circuit boards. At the same time, using a conveyor belt for transportation cannot fix the circuit board, so it is impossible to ensure the position of the circuit board after it enters the curing device, which may lead to the problem of reduced drying effect.

[0004] In the utility model with the application number: CN202321113124.1 and the publication number: CN220072290U, a circuit board coating curing furnace is disclosed, which includes a machine body, a circulation component, and a high-temperature channel. The circulation component includes an air delivery component fixedly installed outside the machine body and a gas collection component arranged around the transmission port for heat recovery. For the circuit board coating curing furnace provided by this utility model, the circuit board is sent into the machine body through a conveyor belt, and it still has the problem that when using a conveyor belt for transportation, it is easy to damage the coating layer when transporting a double-sided coated circuit board, resulting in poor coating effect.
