A kind of baking equipment of pcb board

Abstract

The invention relates to PCB baking equipment. The baking equipment comprises a baking mechanism, and a feeding mechanism and a discharging mechanism, which are arranged at the two sides of the bakingmechanism respectively. The baking mechanism is divided into two layers, wherein the upper layer is a baking device, which comprises a baking conveying device matched with a material loading frame and a baking part; and the lower layer is a circulating conveying device opposite to the conveying direction of the baking conveying device. The baking conveying device is matched with the feeding mechanism and the discharging mechanism through feeding manipulators at the two sides; the circulating conveying device is in butt joint with the feeding mechanism and the discharging mechanism through a circulating transferring device; and the material loading frame is a frame body with at least two layers. The invention is to provide the PCB baking equipment, which adopts the multi-layer material loading frame as a carrier for PCBs moving in the baking equipment, and makes the baking equipment designed into two layers and matched with the two layers of conveying structures, so that cyclic operation of the material loading frame can be realized, the baking efficiency is improved, the baking equipment can be matched with printing equipment and exposure equipment to finish line connection, and operation efficiency of the printing and exposure equipment is not reduced.

Description

technical field [0001] The invention relates to the field of PCB board processing equipment, in particular to a PCB board baking equipment. Background technique [0002] In the process of processing the yellow light of the PCB board, the surface needs to be cleaned through the horizontal line first, and then the photosensitive material is put on the printing equipment, and then the photosensitive material needs to be pre-dried by the baking equipment (oven), and then sent to the exposure machine Expose in the middle, and finally wash through the horizontal line, so as to complete the whole process of image transfer. [0003] Most of the existing baking equipment includes a conveying part and a baking part. The conveying part uses clips to clamp the edge of the PCB board (after printing, there is no photosensitive material only on the edge of tens of microns) and then cooperates with the conveyor chain through the clips, etc. Realize that the PCB passes through the baking eq...

Problems solved by technology

[0003] Most of the existing baking equipment includes a conveying part and a baking part. The conveying part uses clips to clamp the edge of the PCB board (after printing, there is no photosensitive material only on the edge of tens of microns) and then cooperates with the conveyor chain through the clips, etc. Realize that the PCB passes through the baking equipment, and then complete the drying of the PCB board. However, the baking efficiency of the existing baking equipment is not high. When connecting with the printing and exposure equipment, the operating efficiency of the printing and exposure equipment needs to be reduced In order to achieve the effect of on-line operation, or need to be equipped with multiple ovens and one printing equipment to ensure processing efficiency
