Description

Technical Field

[0001] The utility model relates to the technical field of PCBA board processing, in particular to a tunnel type oven used for PCBA board processing. Background Art

[0002] The design and production of printed circuit boards mainly involves removing excess copper from copper-clad boards and forming circuits. Multilayer printed circuit boards also require connecting and conducting each layer. As circuit boards become increasingly fine and small, the processing accuracy is increasing, making the production of printed circuit boards more and more complicated. Now there is a tunnel oven used for PCB processing that is widely used.

[0003] According to a Chinese patent with the announcement number "CN210980705U", a tunnel oven for PCB board processing is disclosed, including a drying chamber, a conveyor belt, an outer frame, a cooling chamber and a third mounting groove, a fifth mounting groove is arranged at the bottom end of the inner part of the outer frame, and a conveyor belt is arranged inside the outer frame above the fifth mounting groove, a first heating tube is horizontally arranged inside the outer frame at one end of the inner wall of the conveyor belt, and a drying chamber is arranged on one side of the inner part of the outer frame above the conveyor belt, a cooling chamber is arranged inside the outer frame on one side of the drying chamber, and an alarm light is arranged at the upper end of one side of the outer frame. The utility model has a baffle plate arranged above the end of the conveyor belt. When the PCB circuit board is conveyed to the end of the conveyor belt, the baffle plate is forced to move forward due to friction resistance, squeezing the spring so that the metal sheets contact each other to form a closed circuit, so that the alarm light is turned on to remind people to collect the materials. When in use, the plates are placed on the conveyor belt. Since the number of plates that can be dried in the drying box at one time is limited, it is necessary to carry out intermittent conveying to avoid conveying too many plates at one time and being unable to dry them. Therefore, a tunnel oven for PCBA board processing is proposed to solve the above-mentioned problems. Utility Model Content
