The invention relates to a novel anti-welding double-sided LED exposure machine, including the frame and conveyor rails, the conveying slide rail is fitted with a frame, characterized by, the machineframe is arranged at the upper and lower parts of the conveying slide rail and is provided with an LED lamp source, the frame includes a lower frame that cooperates with the conveyor rail, the lower frame is hinged with an upper frame, the lower frame is provided with a middle frame which bears the product, and the lower part of the middle frame is provided with a PIN positioning device which is matched with the alignment hole on the middle frame and the product, the lower frame is provided with an alignment device capable of making the middle frame movable, An object of the present inventionis to provide a novel anti-welding double-sided LED exposure machine, A 3-layer frame is adopt, that upper image of the PCB is aligned with the middle frame image through a PIN position device, the middle frame is moved through the aligning device, the low image of the PCB board is aligned with the upper frame image, two or two alignments of the four images are realized, and the welding-proof double-sided LED exposure can be realized, the processing efficiency is improved, and the cost is reduced.
Description
Technical field [0001] The invention relates to the technical field of exposure machines for PCB manufacturing boards, in particular to a new type of solder-resistant double-sided LED exposure machine. Background technique [0002] In the field of PCB manufacturing board manufacturing equipment, the image transfer process mainly includes inner layer, outer layer, and solder mask. At present, the inner layer and outer layer processes are mature for double-sided exposure, but the traditional solder mask process is still single-sided exposure or Use a fully automatic exposure machine to expose on both sides one after the other (also in the middle of the two exposure machines with a plate turning machine to turn 180 degrees), the technical difficulty of the double-sided exposure of the solder mask process is the alignment check. If double-sided exposure is used, a PCB board is required The images on the two sides are aligned with the upper and lower frames respectively. Most of the e...
